Description

The invention relates to the field of informing a person of certain subjects about getting him into an emergency, life-threatening situation, sending these entities an alarm, a call for help and the location of a person in need of help.

Sports, environmental emergencies, construction, military and law enforcement and other potentially dangerous situations often carry a certain level of risk. In the event of an accident or emergency, it is extremely important to be able to communicate and ask for help, in particular, when the user is at rest, without the possibility of moving, for example, being in an avalanche, in a remote place. A clear assessment of the situation may be required for effective assistance and proper prioritization. Also, in the case of group actions, circumstances may arise that one or more members of the group who are disconnected from the rest of the group need help or simply are not able to reconnect.

In the prior art, technical solutions are known which are human-worn alarm devices, for example, GSM Panic Button (www.arsenal-sib.ru/support/documentation/trevozh_knopka_gsm_re.pdf, June 11, 2015 - Certificate of Conformity. ROSS RU .ML05.H01263. GSM panic button. Operation manual. SAPO.425619.006RE). The panic button is a case fixed by a carabiner on clothes or wearable items, onto which control buttons and a light indicator are displayed. Operational notification of an alarm situation is carried out by dialing and / or sending SMS messages to a notification mobile phone or by transmitting data via the CSD channel to the central monitoring console of the integrated security system. The device is equipped with a GSM-module, microcontroller, microSIM-card, battery. The disadvantage of this technical solution is the difficulty of use in case of a sudden change in the situation when a person in a dangerous situation does not have time to use this warning device. Also, the device does not provide information in the absence or disruption of cellular communications.

There is also known a device for alarming threats to personal safety (US 2008182547, July 31, 2008), the body of which is a ring worn on a finger in which a power source, processor unit, microphone, signal transmission unit to an external receiver (mobile phone) are mounted, which in relay mode is associated with a subject that provides security for the user, and a button for initiating the generation of an alarm. The layout of the device does not allow sending an alarm in one short action in case of limitation of hand movement, and the device is not provided in case of disruption of cellular communication.

The closest in technical essence is the personal accident reporting system (PERS) (US 2016307427, 10.20.2016), which includes a wearable device in the form of a bandage on the neck with a pendant, in which there is a microprocessor with a memory containing encoded information about the user, an RF transmitter with an antenna for transmitting alarms generated by the microprocessor to an external emergency message system, for example, the Internet or a private network, a GPS module, a power button and a power supply. To transmit an alarm signal in case it is not possible to use the button, an emergency switch-on of the device is provided when the connection unit for the bandage and pendant is opened. The wearable device of the system provides for its inclusion either with free hands, or in the case of a connection connector with a certain force, which also implies the freedom of movement of the user.

The present invention is aimed at achieving a technical result, which consists in providing the ability to send an alarm and information about a person’s location in one short action, in particular, when restricting the movement of hands, with the possibility of preventing false alarms, with increased efficiency, including in the case of lack of a signal of a cellular GSM network.

The specified technical result is achieved in that the emergency warning device for people who are in a life-threatening situation is made in the form of a housing consisting of a connected base equipped with a mounting unit and a cover configured to install checks on the activation unit and the limiter checks on it, a transmitter board is installed in the housing, on which the power button, microswitch, LED for indicating data transfer, LEDs for indicating discharge, charging and the end of charging are installed, a connector m USB, GPS module, GSM unit, local area network signal transmission unit, Bluetooth module with antenna and SIM card and a power supply connected to the microprocessor bus equipped with a memory unit, while the micro switch is made in the form of a foot pressed by the working part of the receipt with the formation of a shunt, and the limiter checks are made in the form of a tab, brought into the slot on the side surface of the base and spring-loaded in the housing by the working part of the check with an effort to prevent its false operation.

In addition, the check limiter is equipped with a spring.

The signal transmission unit on the local network is configured to communicate with the LPWAN wireless LAN via the open LoRaWAN protocol, which ensures the device’s operability even in the absence of a GSM cellular network.

The microprocessor provides the formation of a signal to cancel the erroneously sent signal when the checks are set back to the working position.

According to the present invention, a wearable emergency warning device is considered for people in a life-threatening situation. This device informs a certain group of subjects and structures that make decisions about getting a person into an emergency situation in which this person needs help.

In a preferred embodiment, the device is a housing 1 (Fig. 1, 2), consisting of a connected base 6 provided with a mounting unit 3, and a cover 7 configured to mount checks 11 of the activation unit 2 and the limiter 4 of the check on it.

The mounting unit 3 is structurally installed in the connectors of the base 6, is equipped with a spring (not shown in the figures) and provides reliable fastening of the entire device to the user's clothing or equipment worn by him (for example, sports equipment). Also on the side surface of the base 6 there is a slot (not shown) in which a tongue is withdrawn, which is a stopper of the check 4, interacting with the check 11 when it is installed in the housing with a certain force provided by the spring 5. The force on the spring and the stop is selected so that to prevent false triggering of checks when a person moves. A USB 22 connector is provided on the bottom surface of the base, equipped with a plug.

The check 11 of the activation unit 2 is installed on the cover 7 of the housing with its working part, the shape of which corresponds to the cover connector, into which the microswitch 17 is displayed in the form of a pressed tab of the tab. The activation unit also includes a strap 12 fixed on the pin 11 with a handle at the opposite end of the strap, consisting of upper and lower covers 13, 14.

In addition, data transfer indicators 9 and charging 10 and a power button 16 are displayed on the cover.

A transmitter board 8 is placed in the housing (Fig. 3), on which a power button 16, microswitch 17, data transfer indication 18 LED, discharging indication indicators, charging process and charging completion 19, 20, 21, USB 22 connector, GPS module are installed 25, a GSM unit 27, a signal transmission unit over a local area network 26, a Bluetooth module with an antenna and a SIM card 29, an accelerometer (not shown in the figures) and a power supply 23 connected to the bus of the microprocessor 24 equipped with a memory unit 28. Microswitch 17, tightened by the working part of the checks 11, forms a shunt with it until device activation when pulling checks. The microprocessor 24 generates a signal to cancel the erroneously sent signal when the checks are set back to the working position.

The data transfer indication LED 18 flashes to notify the user that the device has worked, and a signal for help is being transmitted. The LED radiation is displayed on the cover through the light guide 9.

The sound buzzer 30, when pulling out the checks and the device is triggering, starts to make a loud sound, notifying the user that the device has worked, and a signal is transmitted for help.

The LEDs for indicating the discharge 19, the charging process 20 and the end of the charging 21 notify the user about the state of the battery of the power supply, and their radiation is displayed on the cover through a three-layer optical fiber 10.

The GPS module 25 with a GPS antenna provides the determination of the user's coordinates and is connected with a microprocessor for transmitting location information in a packet of an alarm message about a security threat to a user.

The Bluetooth module with antenna and SIM card 29 organizes high-speed data transmission over the air (2.4 GHz) over short distances using the Bluetooth standard using an antenna to a connected mobile device (for example, a smartphone, Fig. 4).

The GSM 27 unit with an antenna transmits an alarm signal along with information about its location via the GSM / GNSS system.

In addition, the user's location information and the alarm message are transmitted through a local computerized communication tool located nearby and which is a repeater for the device, namely: the signal transmission unit on the local area network 26 is configured to communicate with the LPWAN wireless local area network via the LoRaWAN open protocol, which based on spread spectrum technique. Such a solution, in contrast to the direct spectrum expansion technologies listed above, makes the receiver resistant to frequency deviations from the nominal value, which increases the stability of communication over long distances and reduces energy consumption, which is extremely important in emergency situations.

The alarm transmitted by any of the communication protocols and generated by microprocessor 24 contains information about the user's location, encoded information about himself, which is previously entered into the memory unit and can be sent directly to a user-selected subject and / or group of certain subjects, including in the mode Relays, which may be considered proxies, the Ministry of Emergencies, etc.

The power supply 23 includes a battery, the charging of which is provided through a USB connector.

The operation of the device is as follows:

The device is fixed on the user or his inventory in such a way as to ensure unhindered interaction with the activation unit in a possible emergency.

The device is turned on by a long press on the power button 16. The confirmation of the inclusion is indicated by the data transfer LED 18 and the buzzer sound 30. The device’s location is determined via GPS / GLONASS module 25. When the device is turned on for the first time, global positioning is performed using AGPS to reduce GPS cold start time (GSM block 27). When determining the location in the absence of activity (data from the accelerometer), the interval of GPS requests increases. During activity, the GPS request interval is reduced. If the GPS signal is lost, AGPS is activated for a long time. Cyclical data recording is carried out in the memory unit 28. The accelerometer in the device is used to increase energy efficiency, since in this state of complete rest the device does not spend energy on receiving geo-coordinates and is in a state of reduced activity. At the same time, the microprocessor connects to the mobile phone through the BLUETOOTH 29 module.

In a life-threatening situation, the user pulls out a check of the activation unit, while the working part of the check stops compressing the switch foot and the shunt of the electric circuit opens. As a result of this action, the circuit connecting the microprocessor and the transmitting units is closed, and the alarm is transmitted to pre-selected addresses. When the alarm mode is activated (pulling out checks), an alarm message is transmitted, the GSM unit is activated and the CMC is sent with the last coordinates. At the same time, activation of the signal transmission unit 26 (LoRa transmitter) and the sending of a broadcast message with the last coordinates begins. A message is also being transmitted to the mobile phone (BLUETOOTH 29 module) and an audible indication (buzzer). Turning off the device is activated by a long press on the button.

During operation, to prevent unexpected movement of the checks and false triggering, the device uses a limiter, which prevents the checks from being pulled out completely from the case and is installed during assembly before installing the checks.
