The principle of the monitoring system of moving objects is to track and analyze the spatial and temporal coordinates of a moving object, for example, a vehicle. There are two monitoring options: online - with remote transmission of coordinate information and offline - information is read on arrival at the control room.

For example, a mobile module is installed on a moving object, such as a vehicle, consisting of the following parts: satellite signal receiver, coordinate data storage and transmission modules. The software of the mobile module receives the coordinate data from the signal receiver, writes it to the storage module and, if possible, transmits it via the transmission module.

The transmission module allows you to transfer data using the wireless networks of mobile operators. The received data is analyzed and issued to the dispatcher in text form or using cartographic information.

(utility model patent No. 94367, published June 20, 2010).

The disadvantages of the known automobile satellite navigation system are low sensitivity and noise immunity, as well as high energy consumption.

The objective of the claimed utility model is to eliminate the above disadvantages, namely, increasing the sensitivity and noise immunity of the device, reducing power consumption.

The problem is solved by a moving object monitoring device containing a GPS / GLONASS antenna, an accelerometer, a flash memory, a GPS / GLONASS receiver, a microcontroller, a battery, a GSM based transceiver, technological inputs / outputs, and a voltage regulator, which is additionally equipped with an intelligent battery controller and a power switch made on a BQ24070 chip, a disconnectable input voltage converter, a power supply and control unit GLONASS / GPS antenna, a switch for two SIM cards, a gyroscope and a hardware a capacitive step-up power converter of the 1 Wire bus devices as a voltage stabilizer, and as a battery contains a lithium-polymer battery, while the output of the disconnected input voltage converter is connected to the input of the smart battery and the power switch, to which the lithium-polymer battery is connected, is connected to the output of the power switch a GLONASS / GPS antenna power supply and control unit and a hardware capacitive boost converter for power supply of 1 Wire bus devices, and a switch for two SIM to art is connected to a GSM-based transceiver.

The difference of the claimed device for monitoring moving objects is the possibility of more flexible control of the power system, allowing you to enter several levels of energy saving depending on external conditions. This is achieved by the presence of an intelligent controller of a lithium polymer battery and a power switch 6, executed on a BQ24070 chip, a disconnectable input voltage converter 1. Also, the claimed device is distinguished by the presence of a power supply and control unit GLONASS / GPS antenna 17, a switch for two SIM cards 15 and a hardware capacitive boost power converter 1 Wire 3 bus devices.

The inventive device has increased sensitivity and noise immunity due to improved filtering of the supply voltage of the active GLONASS / GPS antenna and separation of the common wire of the device and antenna. The electrical circuit diagram for turning on the GLONASS / GPS receiver and antenna is shown in FIG. 2. Filtration is provided by a U-shaped filter, consisting of elements C69, L4, C78, C77, L7, C72. In addition, a diagnostic function for the GLONASS / OP8 antenna and detection of breakage conditions, normal operation and short circuit of the power cable are provided. In the event of a break, a low logic level signal is sent from the output of the DA7 comparator to the GPS ANT DET port of the microcontroller 7, during normal operation of the antenna and the current consumption within 5-30 mA, the comparator output goes to a high logical level. When the antenna cable is shorted, the current of the VT11 key with the help of the transistor VT10 and the current-measuring resistor R70 is limited to 55-60 mA and the voltage on the V GPS ANT port of the microcontroller 7 is close to zero. The microcontroller 7 periodically measures the voltage on the V GPS ANT port and, when it falls, turns the VT11 key off at the nGPS ANT OFF odr port. This eliminates the overheating of the VT11 key and the increase in current consumption. Next, the microcontroller 7 periodically turns on the UTI key and measures the voltage on the V GPS ANT port. In the case of eliminating the cable break and increasing this voltage to a value of more than 3.2 V, the unit goes to normal operation.

To power the devices of the 1 Wire bus, a voltage of 4.5-5.5 V with a current of up to 20 mA is required. For this, when using a lithium polymer battery, the use of a boost converter is required. To reduce the cost of the device, a capacitive step-up converter is implemented, powered directly from the port of the microcontroller 7. The node diagram is shown in Fig. 3. The supply voltage of the 1 Wire bus devices is removed from the smoothing capacitor C97 and limited by transistors VT14, VT19 at a level of about 5 V. Thus the need for implementing a PWM controller on the microcontroller 7 disappears, which made it possible to reduce the current consumed by the microcontroller and relieve its resources.

The monitoring device for moving objects is additionally equipped with the ability to turn off the input converter when the vehicle’s battery is exhausted in the parking lot and the device is powered by its own battery in sleep mode. This is achieved by introducing a VT4 transistor. The circuit of the input voltage converter 1 is shown in FIG. 4. The microcontroller 7 periodically measures the on-board voltage of the vehicle and when it drops to 10.8 V, it turns off the converter at a high level on the DC OFF port. As a result, the intelligent controller of the lithium polymer battery and the power switch 6 transfers the device to power from the internal lithium polymer battery 5.

To ensure more reliable delivery of GPRS packets from the claimed monitoring device to the server, a SIM card switch with two holders 15 is used. The circuit diagram of the switch is shown in FIG. 5. The node contains a 9 VA6 analog key chip and two SIM card holders X1 and X2. The default holder is X1. When a message is received from a GSM 14-based transceiver equipped with a GSM antenna 18 that a GSM signal has disappeared or has entered the roaming zone, microcontroller 7 disconnects holder X1 with a signal from the SIM SEL port and connects holder X2.

The inventive device for ensuring reliable uninterrupted operation is also equipped with a power supply stabilizer for the microcontroller 10, a power stabilizer for the GLONASS / GPS receiver 11 and a power supply stabilizer for the input and output signal conditioners 12. The presence of these stabilizers improves the degree of protection of the entire device from external interference and the stability of its operation.

A device for monitoring moving objects works as follows. The monitoring device is installed on civilian ground, water, airborne vehicles or stationary objects for real-time monitoring. The device contains a built-in GPS / GLONASS receiver and a GSM modem. The device determines the current location using the GPS / GLONASS receiver and transmits information to the monitoring server using the GPRS channel of the GSM cellular network. This device can be equipped with additional sensors to perform the analysis and notification functions through the pre-amplifier of the microphone and the final amplifier of the speaker 13 about the presence of fuel, temperature, etc., and can also receive object control commands from the server, for example, to block the engine in in case of excess of speed or sudden braking of the vehicle. When the vehicle is in the zone where the GPRS signal is absent, the device accumulates data on the traveled route in non-volatile memory and automatically issues them when the signal appears. Using the signals of the navigation satellites of the GLONASS / GPS system, the device periodically records satellite signals to calculate coordinates, time, instantaneous speed and distance, sensor readings and transmits them over the GPRS data network using the GSM cellular network. The network used is determined by the SIM card installed in the device. In the absence of a network signal, or if it is impossible to connect (network congestion, lack of funds in the personal account), the device does not transmit data, but stores them in the built-in memory. If it is not possible to transmit data over a cellular network, they can be read from the device with direct connection by removing the device from the car, or by connecting a computer to it in place.

The device can be powered from the on-board network of almost any vehicle or other DC source with a voltage of 6 to 40 volts. The device contains a built-in lithium polymer battery, which provides autonomous operation for more than 15 hours.

Thus, the inventive device for monitoring moving objects has high sensitivity and noise immunity, as well as low energy consumption due to the possibility of more flexible control of the power system, allowing you to enter several levels of energy saving, depending on external conditions. Also, the inventive device has an additional function of analysis and notification of fuel availability, temperature, etc., and can also receive object control commands from the server.
