It so happened that we have only one grandmother at home for a long time, more than 90 years old - my wife and I work, our adult children live separately and, of course, also work. It happens that grandma feels so unwell that it is very difficult for her to get up, go to the phone and call. A cell phone may also turn out to be useless, as it requires some attention and relatively precise manual actions. If you feel unwell, neither one nor the other may be enough. You should also take into account that you may not get through the first time, that your cell phone may not be at hand, that its battery may be dead, etc.

In this regard, I became concerned with finding a solution for immediately sending an alarm signal in the most accessible way for an elderly person with the maximum possible coverage of the alert.

The script is like this: the grandmother presses buttons that are noticeable to her, located in the most likely places of her presence, and a call and SMS from the “Panic Button” subscriber arrives on the cell phones of all relatives involved in the scenario. Everything should be as simple and reliable as possible and require a minimum of maintenance. On the Internet you can find devices and even tariff boards for such solutions, but, frankly, the prices are such that they discourage anyone from using them. So it would be nice to optimize costs. And then, what can compare with the joy of independent creativity in the field of electronics!

Materials used

For the material part, Master Kit modules were taken.

For buttons we will choose MP910 key fobs operating at a frequency of 433 MHz - I took 3 of them.

These transmitters require a corresponding receiver. Since only one channel is needed to respond to a button press, we use the MP911, a 433 MHz remote control receiver operating in “button” mode.

And to send messages and calls we use the MA3401 module - an autonomous GSM-SMS alarm system. This module is also good because it has a memory for 6 numbers, can report a power outage in the house and the temperature in it, and also has some other useful functions that we will not use for now, but will remember for the future!

Having purchased all these devices, I rummaged through my supplies and found a suitable case.

Making a panic button

Since the GSM module is powered by a lithium-ion battery, which is charged from 5V supplied to it via a mini-USB connector, I decided to modify the MP911 receiver module (it is designed to be powered from 12V) a little to power it from 5V. To do this, it is enough to replace the 12-volt relay installed on it with a 5-volt one and supply 5V from the MA3401 directly to the receiver decoder chip.

And we connect the normally closed (so that there is no interference) contacts of the receiver relay to the input of the Button MA3401. Then, when the relay contacts open, an event will occur to which the GSM module will react.

The following photo shows how to supply 5V power to the receiver with decoder.

To place the modules in the case, as well as to replace the standard buttons in the key fobs with more noticeable red and rough ones, I used best friend do-it-yourselfer - a 3D printer. I have a printer designer from Master Kit MC2 with my own modifications. I wrote about them in materials and. I drew and printed stands for the case and buttons. I received both pleasure and practical benefits!

This is the device I got when I assembled everything:

The remote control in the next photo in the center was deliberately left unmodified, as it was, so that the difference could be seen.

Grandma was strictly ordered to hang one remote control button around her neck and not remove it; the other two were glued to double-sided tape in the apartment.

System testing

Checking the functionality of the system:

p.s.: 1. The unit is powered from the USB connector of the computer (thin client with low power consumption), which is always turned on and itself, in turn, is connected to the UPS. The unit contains a lithium-ion battery, which is charged when external power is connected. This process is indicated by a flashing LED. In the device itself, you can enable SMS notification mode about loss of external power.

2. No problems were noticed with noise immunity. Between the key fob and the receiver there is a “friend or foe” poll. The receiver should not respond to third-party signals. But, if it suddenly works by accident, an extra call won’t hurt. The panic button system itself is not the only way of monitoring - there is video surveillance with a motion sensor, for which the Hikvision DS-2CD2412F-IW camera is used.

Panic button for the elderly

From this article you will learn:

What does a panic button look like for older people?

Who is entitled to a free alarm bracelet for an elderly person?

Where and how much to buy a panic button for an elderly person

How to make your own panic button

Russia has approximately 40 million elderly people and approximately 13 million people with disabilities. These are elderly people, often with disabilities and various serious illnesses. Elderly people definitely need to be able to call for emergency help. Such tasks are carried out thanks to panic buttons for the elderly or panic bracelets for the elderly.

Free panic button for the elderly and other “rescuer” gadgets

In Moscow, it is planned to equip elderly and disabled people with a simple “panic button” technical device. Prior to this, the “panic button” service was provided only to war veterans who were left without the care of relatives. Externally, the panic button device is no different from a regular mobile phone. Pressing one of the buttons on this device will immediately connect the elderly person with dispatchers at the capital's Veterans' Home. The dispatcher is responsible for accepting independent decision which service to call - fire brigade, ambulance, police squad, etc. Some of these devices produce a loud beep to attract people's attention.

Subsequently, the idea of ​​a “panic button” for older people was improved, transforming into a “panic bracelet” resembling wrist watch, but somewhat larger. The alarm bracelet has great capabilities. The dispatcher monitors the elderly person in real time. The use of the latest methods allows the signal from the alarm bracelet to be displayed on an electronic display, making it easy to calculate the exact location where the appropriate service should be sent in case of emergency.

The dispatch service screen can display names, addresses, diagnoses, and telephone numbers of neighbors or relatives. Alarm bracelets are equipped with sensors that transmit indicators of body temperature, blood pressure and pulse. If an elderly person falls, the fall sensor will be activated, and the dispatcher will know the exact location of the incident. The dispatcher must immediately contact the elderly person. If old man does not respond, the dispatcher must call emergency medical care. The alarm bracelet is also equipped with a sensor that will go off if the strap comes loose.

Similar ones are being introduced in the Moscow region innovative technologies on the installation of personal rapid response devices “Arkan”, providing protection for the elderly and disabled. Reutov, Istrinsky, Klinsky and Stupinsky municipal districts successfully use devices of this kind for older people.

The system monitors the health and protection of an elderly person around the clock, promptly calling emergency medical help if necessary. Please note that this device is provided to older people free of charge, thanks to funds allocated from the regional budget. The Arkan apparatus consists of a complex technical equipment placed in the home of an elderly or disabled person.

The system is equipped with electrical equipment, radio equipment, alarm and triggering security devices: control panels, an additional power battery, units that transmit information, sensors that respond to door openings, an “alarm bracelet” with an emergency button. This button gives an alarm signal to the operator at the district social service.

Panic button for an elderly person: where and how to get

In 2011, Moscow and St. Petersburg began to participate in the “Panic Button” social project. As part of this project, elderly residents of these cities who have benefits received the privilege of being served free of charge by the Panic Button system. Services are provided by district Integrated Social Centers. residential services for older people.

To receive an alarm bracelet with an emergency help button, an elderly person must call the center social services population at the place of residence, having prepared the documents listed below:

• health insurance policy;

  certificate of a participant or disabled person of the Second World War;

  pensioner's ID;

  certificate of disability (if available).

Sometimes you will need a medical certificate stating that the provision of the “panic button” service is not contraindicated for an elderly person.

In the case when an elderly person cannot collect all the necessary certificates himself, he will need to use the help of his legal representative by drawing up a power of attorney certified by a notary.

Elderly Muscovites with benefits are given an “alarm bracelet” free of charge thanks to budget funds. Others can connect to surveillance systems for a fee. The population often requests this service, as a result of which many organizations and firms have begun to provide older people with their own monitoring systems.

Panic button for older people: the price of a “life button”

In the West, cellular medical tracking services have been successfully operating for 30 years. Russian Federation I started promoting similar projects not so long ago, but these projects turned out to be in great demand. Thanks to the “Life Button” project, which turned out to be the first ambulance call system in Russia for the elderly and disabled, more than one life was saved.

The Life Button project was recognized as one of the 3 best startups of 2011 according to Forbes. In July, the RINTECH company, part of the IT Group, signed an investment agreement with the “Life Button” program. The project received investments in the amount of 35 million rubles. The creators of the “Life Button” project are planning to launch a new product on the market - a life button for children.

The Life Button device has two models. The first model is intended for active people. The model is similar to a telephone with large buttons and a clear menu, equipped with an SOS key. The device will be easy for any elderly person to understand. By pressing the “rescue button”, the alarm signal will immediately go to the Help Center, where a group of doctors and psychologists are on duty around the clock. Based on the alarm signal from the device, the coordinates of the elderly person are determined to send help.

The second model is intended for sedentary people. The model looks like a waterproof bracelet with a built-in SOS button and a fall sensor. Pressing the SOS panic button or an alarm signal from a fall sensor immediately goes to the Help Center. Automatic speakerphone allows the specialist on duty to determine the degree of risk and, if necessary, call the elderly person for help.

It is noteworthy that all the necessary data about the owner of the “panic button” is already contained in the system’s memory. Having received an alarm signal, the specialist will call relatives or neighbors whose telephone numbers the elderly person provided earlier, and will also notify the Emergency Doctor about important information by illness or allergic reaction for some medications.

Alas, not all Russian pensioners can purchase the “Life Button”. The “Life Button for Active” device costs 4,730 rubles, subscription service will cost 580 rubles. monthly. The “Life Button for the Inactive” device costs 9,990 rubles, subscription service will cost 990 rubles. monthly. You can buy the “Life Button” device, for example, in MTS stores.

If buying a panic button for the elderly is expensive for you...

In this case, the button can be made by yourself! You will need several Master Kit models. To make a panic button, stock up on three MP910 key fobs operating in the 433 MHz range.

Such transmitters need a corresponding receiver. To respond to a panic button, one channel is enough. We use MP911, a 433 MHz remote control receiver operating in “button” mode.

And in order to send a message and call, use the MA3401 module - an autonomous GSM-SMS alarm system. This module has the advantage that it stores 6 numbers. The device reports the loss of light in the room, calculates the air temperature in the room and has some other useful functions.

Once you have purchased all the necessary parts, find a suitable box for the case.

The GSM module is powered by a lithium-ion battery, which is recharged from 5V received from the mini-USB connector. Therefore, convert the MP911 receiver, designed to be powered from 12V, to power from 5V. To do this, you will need to replace the 12 Volt relay installed on the module with a 5 Volt relay and run 5V from the MA3401 directly to the receiver decoder chip.

To avoid interference, carefully short the relay contacts in the receiver and ensure a clean connection to the input port of the Button MA3401. When the relay contacts are disconnected, a reaction from the GSM module will be observed.

The following photos show the 5V power supply circuit to the receiver with decoder.

To place modules in a housing box (or to make the standard buttons on key fobs more noticeable red and rough), we recommend using one of the best friends of DIYers - a 3D printer. Let's take the designer printer from Master Kit MC2. Let's draw and print stands for the case box and buttons.

This is the device that will come out after assembly:

The remote control in the next photo (it is placed in the center) is intentionally left unfinished so that you can see the difference.

In the next video you can see how to make a panic button for the elderly at home:

What could be better than a panic button for the elderly?

In cases where panic buttons for elderly people are prohibitively expensive, the problem of the safety of an elderly person can be solved in other ways, which no less carefully monitor the movements of pensioners and immediately come to their aid in necessary cases.

The first of these methods is a GPS tracker developed by RusLink (WHERE ARE MY service). The mini-beacon helps determine the movements of older people with an accuracy of up to 5 m by tracking their location via GPS satellite signals.

GPS trackers immediately inform loved ones over the phone when older people leave home, deviate from the familiar route to home, go beyond the boundaries of their area of ​​residence, or call for help by pressing the SOS panic button on the beacon. These and other notification parameters are configured in your Personal Accounts on the website www.gdemoi.ru. In addition, the device reminds you to charge the battery in a timely manner and reports no feedback for a long time.

You can find out the location of elderly people and view their route of movement on a regular computer, smartphone using the mobile site gdemoi.mobi or through an SMS command with the word “where”. A detailed electronic map with indicated streets and house numbers will help in a matter of seconds to determine the location of a pensioner and, if necessary, come to the rescue.

The GPS tracker has one panic button. The moment you press it, the signal sign will be instantly sent to relatives in the form of an SMS or e-mail message. The text of the message will indicate the time and address from which the alarm signal came. You can specify any number of relatives for notification.

Basic monitoring services are free. An additional set of services will cost 7 rubles daily. A GPS tracker costs around 6,600 rubles. By the way, GPS trackers can be purchased or rented, which costs 200 rubles. per day. However, today such services are available only to residents of Moscow and Yekaterinburg.

A similar service is offered by some mobile operators. For example, MegaFon has developed its own model of the MegaFon C1 phone, which can operate in standby mode for more than 7 days without recharging. The model is equipped with an SOS panic button, by pressing which automatic SMS will be sent to the programmed numbers. This way, in an emergency, older people can urgently contact their relatives.

Some time ago, the Ministry of Emergency Situations introduced a free mobile program “Mobile Rescuer”, intended for smartphones on iOS and Android. The application automatically finds out where the elderly person is and determines the closest emergency services. The program is equipped with an alarm button, which, when pressed, calls the appropriate services and at the same time notifies relatives that their relative needs help.

After downloading the free application, you need to enter the phone numbers of relatives into the list of emergency contacts: pressing the emergency button “Send SOS” will give them an automatic signal in the form of SMS messages. In addition, the program includes a reference information section on how to act in emergencies, how to provide first aid to elderly people, what medical institutions and first responders (including their contacts) are closest.

Smartphone app stores offer several other similar programs for iOS and Android devices. For example, let's call the bSafe program, which allows older people to send an alarm signal to their relatives in two clicks, who, thanks to this program, have the opportunity to track the movements of their grandparents using GPS, as well as make an imitation of a “false call” immediately or after a few minutes. This application has a premium feature in the form of a loud siren and video recording in one click.

A similar SOS-SMS program makes it possible to immediately send SMS and e-mail alerts to pre-registered telephone numbers of loved ones or security service departments. The message texts indicate the location of the elderly pensioner and a dictaphone audio recording, which starts automatically when the program is activated. Thanks to this, relatives will be aware of what happened to their loved one and will be able to come to his aid.

To summarize: there are many ways to help older adults in emergency situations. All that remains is to choose the right solution in advance. The “mobile rescuer” in your pocket has provided assistance to elderly people more than once. These security measures will ensure the protection of your loved one, as a result of which both he and you will feel much calmer.

1.7.1. How to make a “panic button”

In the author’s version, a “panic button” is installed to effectively provide two important tasks: calling for help for elderly relatives and a pregnant wife, as well as prompt notification in the event of an unauthorized robbery entering an apartment. That is why it is important to choose a place to install a “panic button” (hereinafter referred to as TC).

In Figure 1.35. An illustration of the installation of a TC next to the front door is presented.

When choosing a location, it is important to take into account factors such as inaccessibility for children (to eliminate/minimize accidental presses, TCs are raised to a height of more than 1.2 m from the floor level) and, conversely, accessibility - for pressing during an emergency when the roads are bad that seconds, but also milliseconds are decisive (robbery and other unauthorized cases).

As the “panic button” itself, I use an industrial fire alarm device (button) - with a fixed position and with a locking key (see Fig. 1.36), which excludes unauthorized or false alarms during mechanical blocking.

Rice. 1.36. Appearance of a mechanical “panic button” with state fixation and blocker

This button allows you to control and record the click - to know that the click took place. The “panic button” itself can be installed on the door frame, on the wall, or generally in any suitable place indoors.

After opening the button housing, connect the flat cable to the special terminal block (Fig. 1.37-1.39) - and the “panic button” is ready.

Rice. 1.37. View of the inside of the “panic button” housing

Rice. 1.38. Appearance of another “panic button” housing

Rice. 1.39. View of the insides of another “panic button” housing

The contactor in the “panic button” is implemented using a microswitch of the MP3-1 type, which has three contacts and two positions. The conductors must be connected in accordance with the pinout: the designation on the TK board (Fig. 8) - to the COM contact - the main contact of the switch, the contact with the designation NC is constantly closed with COM in the depressed (main, nominal position of the button), and the contact with the designation NO is closed with COM when you press the TC (and remains in electrical contact until the button lock is mechanically unlocked by the key).

The other part of the two-wire cable is connected directly to the remote sensor circuit board of the MT9000 system described above, parallel to the reed switch contacts as shown in Figure 1.40.

Rice. 1.40. Connecting an alarm button to a universal sensor - to the reed switch contacts

Attention, important! The universal sensor has a reed switch with short-circuit contacts. Thus, its contacts are closed in the presence of a magnetic field near the reed switch, i.e., the magnet, and open when the reed switch moves away from the magnet. Based on this principle, the response system for opening/closing the front door was built. The improved “panic button” system will work on the same principle.

The total length of the cable - to localize possible interference - should be minimal, no more than 50 cm.

A view of the contactor (conductor connection diagram) is shown in Figure 1.41.

Rice. 1.41. Diagram for connecting conductors to the contactor terminal block

It is important to note that at the moment the reed switch (and TC) contacts are closed, the MT9000 system immediately sends an SMS to all numbers programmed in its memory. Moreover, sending SMS is not related to either the duration of contact closure or the condition of their opening.

That is, at the first moment of time, an sms will be sent regardless of how long the TC will be in a fixed position (closed state of the reed switch contacts in the universal remote sensor).

SMS will be sent once. It is also important that the system will send the next SMS at the moment when the TC is unlocked, that is, the reed switch contacts are open. Thus, it is convenient to control (remotely, via SMS) both the time of actual operation of the TC and the unlocking time.

Of course, the locking key for the TC system should be kept away from “casual” eyes.

For reliable and stable operation of the system, it is important to fulfill three conditions.

1. Ensure reliable communication between the sensor - a universal remote unit and the alarm base (no more than 10 meters - preferably in line of sight).

2. Periodically - once a month - monitor the battery voltage in the sensor by requesting an SMS command to the base unit and responding from it (specified in the instructions for the MT9000 alarm).

3. Regularly, once a month, forcefully check the serviceability of the system.
