Abstract

The utility model relates to road safety systems. Microcontroller 7 transmits navigation information about the location of the vehicle, its speed to the GSM / GPRS module with antenna 8, which, using the SIM card 5, authenticates the device in the GSM network. Information from the GLONASS / GPS / GALILEO / BEIDOU 12 satellite navigation receiver via the standard NMEA protocol enters the microcontroller 7, in which it is further converted, in the event of an accident with the vehicle (overturn or collision), in the form of position information (latitude, and longitude), this information is transmitted in the form of an emergency message to the transport security service ERA GLONASS or its foreign analogue eCall. If the vehicle hits the places where there is no reception of navigation signals from satellites, the information about the vehicle's location is determined by the data received by the inertial reckoning system. EFFECT: even in the absence of a satellite navigation signal, in case of an accident with the vehicle, for example, in a long transport tunnel, an alarm message about the accident will come with navigation parameters, which will allow a quick search for victims - it will provide them with the "Golden Hour" mode. In the case of transportation of dangerous goods, control over the condition of the cargo is provided by connecting additional sensors.

Description

ERA GLONASS devices ensure transport safety. The device installed in the vehicle (TC) determines the location of the vehicle, receiving navigation information from satellites of the GLONASS / GPS system, and in the event of an accident, establishes communication and transmits a message to the transport security system "ERA-GLONASS" or its foreign analogue "eCall ". The information about the location of the vehicle transmitted in this way provides emergency services with an accelerated search, and the victims in an accident are given the "golden hour" mode. The alarm signal has a priority status and will be promptly transmitted through any cellular operator.

The history of ERA GLONASS (published at http://EraGlonass.ru) / 1 / began after the introduction of the eCall system. ECall is a European project of an integrated automotive system designed to promptly inform emergency services about road accidents As a result of intensive negotiations, a full-fledged launch across the entire United Europe (plus Switzerland, Norway and Iceland) took place in 2015. To demonstrate the possibility of joint work of eCall and the domestic system "ERA-GLONASS", a joint successful project was carried out on the borders of Finland and the Leningrad region. The essence of the ERA GLONASS project is as follows - specialized modules integrated into automotive systems determine the exact coordinates by a signal from satellites, and, if necessary, in the event of an accident, send this information via cellular communication channels and notify emergency services. In the event of an accident, the system can be turned on either in manual mode or activated automatically by receiving a signal from the vehicle's internal sensors. ERA-GLONASS terminals in Russia are to be equipped with vehicles of all categories M (passenger vehicles) and N (heavy vehicles). In addition, in the Russian system, it is mandatory to use the navigation signals of the GLONASS system (in eCall - GPS and GALILEO). At the same time, in a key area, namely in the use of In-Band Modem (a tone modem that transmits data within an established voice connection) to transmit a minimum set of MSD data (coordinates, time, VIN, etc.), as well as establishing two-way voice communication in case of an emergency - both projects are identical.

Known device "Inertial-satellite module and complex inertial - satellite navigation system, communication, lighting, control and monitoring" (RU 2036432 C1, IPC G01C 21/24, G01C 23/00, publ. 27.05.1995) / 2 /. In this device, control and safety are achieved due to the fact that nine integral parameters are determined in the inertial-satellite module for each of the errors in three coordinates and three projections of linear velocity. By placing a number of inertial-satellite modules on the body of the object, it becomes possible to determine the linear and angular deformations of the object in blocks for determining linear deformations and blocks for determining angular deformations. Due to a technically complex solution, this device possesses redundant information that allows solving complex, applied and even scientific issues due to the use of a large volume of measuring equipment, which significantly increases the cost of the device. It is bulky and cannot be used in compact devices such as a vehicle.

For the prototype we take the closest in technical essence to the claimed utility model DEVICE / SYSTEM FOR CALLING EMERGENCY OPERATIONAL SERVICES EMG-1 (CSS) (published at http://eraglonass-msk.ru) / 3 /.

CSS is intended for installation in vehicles used for passenger transportation. CSS refers to the ERA GLONASS emergency response system.

The product can: transmit a message in case of road traffic and other incidents in manual and automatic mode;

Maintain two-way voice communication with emergency operational services over mobile radiotelephone networks.

The CSS provides reception of GLONASS and GPS navigation systems, and transmission via GSM networks to the ERA GLONASS emergency response system server, the following information:

own identification number;

navigation data (latitude, longitude, date and time of the incident);

sign of pressing the SOS button.

The product is connected to the on-board network, sensors and actuators of the vehicle using the main loop according to the electrical diagram.

The CSS contains a GLONASS / GPS module, which is designed to receive signals from navigation satellites, a GSM module, which provides information transfer to a dedicated server and establishes a connection with the infrastructure of the ERAGLONASS transport security system, all information arriving for processing flows into the microcontroller from the sensors, in the internal memory, intermediate results are accumulated, the accelerometer measures the level of accelerations (in order to determine the accident that has occurred), the gyroscope reacts to a vehicle overturn in an accident, the RS-485 and USB interface allow you to both connect additional equipment and download operational information, a microphone, a speaker and a call button SOS provide speakerphone and emergency calls, the tamper switch provides protection against unauthorized opening of the USB.

The disadvantages of the proposed prototype include:

1. When the vehicle enters the places of high-rise buildings due to the repeatedly reflected received navigation signal, an ambiguous determination of the vehicle's location occurs.

2. If the vehicle enters the zone of unsure reception of navigation signals (dense forest) or in an area where there is no reception of navigation signals (auto tunnels, as well as bridges with powerful metal structures), it is impossible to determine the location of the vehicle using GLONASS / GPS signals.

3. After a long stay of the vehicle in the area of poor reception or complete absence of a signal from GLONASS / GPS satellites, it is possible to increase the time spent on restoring the determination of the vehicle's position.

The list of shortcomings in the operation of CSS is taken from section 2 "Operation manual", page 13.

The problem solved by this utility model is to eliminate the above disadvantages by creating a duplicate coordinate system using the Dead-Reckoning technology. Dead Reckoning (DR published at http://macrogroup.ru) / 4 / - technology of inertial reckoning, calculating geographic coordinates, speed and direction of movement using inertial sensors (speed sensor and direction sensor). The technology is used in satellite navigation modules as an auxiliary one. It allows you not to interrupt the operation of the satellite navigation module and not to stop issuing information messages in the event of a sudden or prolonged loss of signals from satellites. Most often, this function turns out to be relevant when driving through long automobile tunnels, bridges with complex metal ceilings and when moving in settlements with dense buildings, a large number of high-rise buildings, which limits the visibility of the open sky.

The utility model relates to devices used for continuous vehicle monitoring even in conditions of blocking the signal from navigation satellites. To obtain the necessary information, a device with an integrated gyroscope and accelerometer and appropriate software is used, which creates conditions for uninterrupted positioning and obtaining continuous navigation information about the location of the vehicle.

These technical results are achieved due to the fact that a device containing a GLONASS / GPS satellite navigation receiver module, a GSM module providing both transmission and exchange of information, a microcontroller for processing digital information, an internal memory for storing digital information, an accelerometer and a gyroscope are sensors that in addition to the main functions, they additionally ensure the stable operation of the inertial number system, input / output ports (RS-485, USB2.0 interface), a headset with an amplifier and an SOS button, providing speakerphone and calling emergency services, according to the utility model, the GLONASS / GPS / module is introduced GALILEO / BEIDOU, which provides work with the navigation system, which is currently a source of stable information. An external antenna GLONASS / GPS / GALILEO / BEIDOU is being introduced, for reliable reception of signals from navigation satellites - which removes questions about limiting the location of the device in the vehicle cabin (possible signal shielding in the case of an internal antenna), an HF connector for connecting an external antenna. In this case, the output of the input supply voltage connector is connected to the input of the power supply with a built-in battery, the output of which is loaded on the supply inputs of the accelerometer and gyroscope, GSM / GPRS module, microcontroller, tamper sensor, internal memory, headset, GLONASS / GPS / GALILEO / BEIDOU receiver, through which and the HF connector, the supply voltage is supplied to the external GLONASS / GPS / GALILEO / BEIDOU antenna.

The drawing shows a functional diagram of the device.

The device contains a power supply unit with a battery 1, connected by the power input to the output of the power connection connector 2, as well as to the power inputs of the devices 3, 4, 5, 6, 7, 8, 9, 10. Power supply through the GLONASS / GPS / GALILEO / BEIDOU 12 and HF connector 13 are fed to an external GLONASS / GPS / GALILEO / BEIDOU 14 antenna, which selects and transmits signals from visible satellites of the GLONASS / GPS / GALILEO / BEIDOU constellation to the GLONASS / GPS / GALILEO / BEIDOU 12 receiver. The GLONASS / GPS / GALILEO / BEIDOU 12 receiver, according to the standard NMEA protocol, calculates the geographical coordinates of the object and transmits information about the location, speed and time to the microcontroller 7, in which the information is processed and the controller 7 is synchronized with the high-precision UTC time. Microcontroller 7 is connected to the GSM / GPRS module with antenna 8, which is connected to the SIM card 5, which is necessary for authenticating the device in the GSM network. Microcontroller 7 is connected to accelerometer and gyroscope 3, SOS button 4, tamper sensor 6, internal memory 10 and input / output ports 11. The navigation signal processed in microcontroller 7 is fed to the GSM / GPRS module 8, from where, through the internal antenna it enters GSM network, while SIM-card 5 identifies the operator of the GSM network. In the event of an accident with the vehicle (overturn or collision), this channel is used to transmit an emergency message to the ERA GLONASS transport security service. The joint use of GLONASS / GPS / GALILEO / BEIDOU navigation systems provides stable positioning, since the number of visible satellites increases many times over, and in addition, many satellites emit in the new L5, L6 bands, which increases the reception ability in dense urban areas. The development of technology allowed Skytraq to create a new generation satellite navigation receiver with support for L1 L2 L5 L6, GLONASS / GPS / GALILEO / BEIDOU with an accelerometer and gyroscope built into its case, sharpened for operation as part of an inertial system (published in http: // wireless -e) / 5 /. A headset with an amplifier is necessary for communication with the operator of the ERA GLONASS system - through it, it is possible to clarify both the circumstances of the accident that occurred and to obtain additional information.

The operation of the transport safety device begins with starting the vehicle's engine. In the operating mode, the navigation information is read out and at the same time the inertial number system is started. In the event of an accident, the accelerometer specifies the impact force, and the gyroscope, in the event of a vehicle overturning, specifies its value. If the limit values are exceeded, an alarm is generated automatically, but the SOS button can also be activated in manual mode. In case of loss of reception of signals from satellites, the information of the inertial number system is connected. The headset is necessary for the transmission of clarifying circumstances or for obtaining additional information, and the tamper switch guarantees against unauthorized entry into the transport security device. In addition, if the vehicle carries out the transportation of dangerous goods, then additional control over the condition of the cargo is provided by connecting digital sensors to the transport safety device through the input / output ports.
