Description

The invention relates to the field of navigation (determining the location of the vehicle) and can be used to monitor vehicles (TC) using GLONASS / GPS signals and to inform about the current location of the object via GSM networks.

Famous satellite beacon for monitoring freight and transport (US Pat. RF №173225, publ. 08/16/2017), which is a device made in a secure case and containing modules GLONASS / GPS and GSM. The device is designed to determine the coordinates of the location of a moving object anywhere in the world and process technological parameters with the subsequent transmission of data via satellite communication channel or GSM channel.

A device for monitoring mobile objects is known (US Pat. Of the Russian Federation No. 150328, publ. 10.02.2015) containing a GPS / Glonass antenna, an accelerometer, flash memory, a GPS / Glonass receiver, and a microcontroller.

The device is aimed at increasing the sensitivity and noise immunity, reducing power consumption.

A personal GSM communicator with a GLONASS / GPS receiver is known (US Pat. Of the Russian Federation No. 125423, published on 02/27/2013). The device includes a personal GSM communicator with a GLONASS / GPS receiver, a touch screen display, a microprocessor, a rechargeable battery, a power supply module, a speaker, Flash memory on an SD card, a built-in GSM antenna, a GSM modem, a Bluetooth module. The device is aimed at improving the accuracy of determining the location of a moving object.

The task is to develop a device for satellite monitoring of vehicles, allowing not only to record the coordinates of the vehicle, but also to memorize user coordinates, the current speed of the vehicle, altitude, the current date and time.

The technical result, which is aimed at achieving the claimed utility model, is to provide an additional function for memorizing user coordinates and other information.

To achieve the above technical result in a satellite vehicle monitoring device containing a microcontroller, display, GLONASS / GPS and GSM modules, a memory card placed in a housing, a button is added to the housing to memorize the coordinates of locations marked by the user and connect to the vehicle’s electrical network. ), while the current coordinates of the vehicle are recorded on the memory card every 4 seconds with a display.

Due to the presence of these signs, enhanced functionality is provided by means of a button located on the body for memorizing the coordinates of places marked by the user.

The proposed satellite vehicle monitoring device is illustrated by the drawings shown in FIG. 12.

FIG. 1 schematically shows a device in the form of modules; FIG. 2 - a general view of the device.

Presented in FIG. 1 the modules of the vehicle satellite monitoring device are as follows:

1 - power supply;

2 - microcontroller (MK);

3 - GLONASS / GPS module;

4 - GSM module;

5 - memory card;

6 - sign-synthesizing display.

As a power source, the device uses power from the vehicle’s electrical network (DC voltage + 12V .. + 14V). FIG. 2 (general view of the assembled device) are indicated:

7 - device case;

8 - plug connection to the electrical network of the vehicle;

9 - button for memorizing the coordinates of places marked by the user during the trip.

The device for satellite monitoring of transport is made in the housing 7. The connection to the vehicle electrical network is carried out using a plug 8 of the connection. On the housing 7 of the device handed a sign-synthesizing display 6 and a button 9 for storing the coordinates of the places marked by the user during the trip. The sign-synthesizing display 6 is selected on the basis of the following representations. Compared with touchscreen, graphic displays, the sign-based display is easy to use and use, has lower power consumption, high luminance brightness, maximum viewing angle without loss of display quality. The wide operating temperature range, which allows it to work even at (-40 ° C), makes it possible to use the developed device even in our northern winter (for graphic displays, the image will “freeze”, as is usually the case with mobile phones in severe frost).

The principle of operation of the device is as follows.

Before operation, the device is connected to the electrical network of the vehicle using a plug 8 connection. The power supply unit 1 normalizes the input voltage (+ 12V .. + 14V) to the levels necessary for the stable operation of the remaining modules that make up the device: + 5V to the microcontroller 2, GLONASS / GPS module 3, memory card 5, the sign-synthesis display 6, + 4V to GSM module 4.

Microcontroller 2 begins to work according to the laid algorithm, initializes interaction with the GLONASS / GPS module 3, GSM module 4, memory card 5.

After initialization has been completed, the corresponding information is displayed on the sign-synthesis display 6. Next, the microcontroller 2 goes into normal operation. In normal operation mode, the device using the GLONASS / GPS module 3 calculates the current coordinates of the vehicle and writes them to the memory card 5 with a period of 4 seconds, i.e. every 4 seconds, with an output to the sign-synthesizing display 6. Together with the current coordinates, the current speed of the vehicle movement, the height above sea level and the current date and time are recorded on memory card 5. A period of 4 seconds was chosen experimentally as the optimal time interval. Since the coordinates are recorded on a memory card, on the one hand, more frequent recording, for example, every second, will lead to its faster damage due to the limited number of recording cycles. On the other hand, a rarer recording of coordinates (with an interval of more than 4 seconds) leads to a distortion of the route of the vehicle when it is built using popular mapping systems. The route line is not smooth, but angular, thereby deteriorating the user's perception of the movement of the vehicle.

Using the GSM module 4 with the period set by the device user, is transmitted to the system server, or using an SMS message to a previously entered phone number, information about the current vehicle position in the form of coordinates with the possibility of further identifying the vehicle position in popular map systems.

Any actions performed by the microcontroller 2 are also visualized on the sign-synthesizing display 6.

The device has a button 9 for memorizing the coordinates of places, which is located on the housing 7 of the device. The user of the device can mark his places of interest, which he drives, for this he needs to press the button 9, and the coordinates of this place with the corresponding service information will be saved on memory card 5.

To complete the work, it is necessary to disconnect the device from the vehicle’s electrical network.

Upon completion of the work on information stored on memory card 5, you can build a route of the vehicle using popular mapping systems, determine the vehicle speed, altitude and its time of movement, view the user-marked places on the map.

In the proposed utility model, not only the coordinates, but also the current vehicle speed, altitude, current date and time, user information are recorded on the memory card.
