In addition, the system is equipped with additional service software installed on an external device with the ability to read code information from the second archive exclusively through a GPRS or CDMA modem and display information on the monitor screen of the external device in the form of a graph of the level or fuel consumption in the fuel tank and vehicle operating modes, moreover, the vehicle operating modes are displayed directly on the graph of changes in the level or volume of fuels and in the tank in the form of a sequence of colored sections, the color of each of which is pre-programmed and limited by the time of registration of the occurrence of the next or corresponding event.

As options, the registration unit can be equipped with a display panel and means for selecting an indication mode and connected in parallel to the said sensors, or the fuel level or volume sensor is connected to one of the inputs of the registration unit, and the pointer is connected to one of its outputs. The display panel and the means of selecting the display mode can be made in the form of a stand-alone device, which is connected to the said port for outputting information from the archive and entering parameters.

Comparison of the claimed technical solution with the prior art in scientific, technical and patent documentation as of the priority date in the main and related sections shows that the set of essential features of the claimed solution was not known, therefore, it meets the patentability condition of “novelty”. In addition, the proposed technical solution can be implemented and implemented industrially, efficiently, reproducibly and, therefore, meets the condition of patentability "industrial applicability".

The essence of the utility model is illustrated by drawings, which schematically depict one of the main options for implementing the system (figure 1) and display information (figure 2).

The system contains (Fig. 1) a registration unit 1, consisting of a microcontroller 2, made in the form of a single-chip microcomputer, an indication panel 3, an archive 4, an electronic clock 5 real-time, an autonomous power supply unit 6, matching amplifiers 7, connected through inputs / outputs 8 , 9, 10 and 11 of the registration unit with the outputs of the sensors of the level or volume of fuel, engine speed, travel speed and VK power switch, port 12 for outputting information from the archive and entering parameters, fuel gauge 13 and antenna 14. The registration unit is equipped with a second archive om 15 arranged in the single-chip microcomputer 2, an auxiliary input 16, the receiver 17 GPS-signals, GPRS or CDMA-modem means 18 and 19 select display mode. The antenna 14 is connected through an additional input 16 to the receiver 17 of the GPS signals, and the receiver 17 of the GPS signals, GPRS or CDMA modem 18 and the means 19 of the indication indication - to the ports of a single-chip microcomputer.

Alternatively, the display panel 3 and the means 19 for selecting the display mode can be made in the form of a stand-alone device connected to the mentioned port 12 for outputting information from the archive and entering parameters (not shown in the drawings). In this case, port 12 can be performed, for example, in the form of an RS-232 interface, ISO 9141, SAE J1708 (SAE J1587), etc.

As sensors or signals of sensors of engine speed (ICE), speed of movement and power-on, signals of devices of standard electric equipment of a vehicle can be used, namely, signals from terminals W of the generator, B7 of the tachograph or speedometer and terminal 15 of the lock

inclusion of ignition (starter and devices).

The system is also equipped with additional service software, one part of which is recorded in the non-volatile memory of a single-chip microcomputer, and the second is installed on an external device, for example, a computer (server) of an enterprise ACS (an external device is not shown in the drawings) and providing the ability to read code information from the second archive exclusively through a GPRS or CDMA modem with subsequent display on the monitor screen of an external device in the form of a graph of changes in the level or fuel consumption in the fuel m tank operating modes of the vehicle and the geographic coordinate. In this case, the vehicle operating modes are displayed directly on the graph of changes in the level or volume of fuel in the tank.

The system operates as follows.

In the initial state (when the VK switch or ignition switch is turned off), the device is powered by the battery (battery, in the drawing of the "+" and "-" terminals) of the vehicle, when the battery is disconnected - in micro consumption mode from the autonomous power supply unit 6. In this case, the microcomputer 2 provides periodic (through programmable time intervals) measurement of the signal of the level sensor or fuel consumption, encoding and parallel archiving of data in time coordinates in archives 4 and 15 with the formation and transmission of the corresponding signal of the current value of fuel consumption to pointer 13 and / or display panel 3. At the same time, the receiver 17 GPS signals are receiving navigation information received through the receiving antenna 14.

When you turn on the power or when receiving a special encoded request from an external device (determined by the microcomputer software 2), this information is read from archives 4 and 15 and transmitted via GPRS or CDMA modem 18 to the server of the external device.

If any of the events occurs, for example, “Starting the engine”, “Starting the movement”, “Turning off the power”, “Draining fuel”, etc., the microcomputer 2 additionally reads from the receiver 17, encodes and sends information to archives 4 and 15 about the geographical coordinates of the occurrence of the event.

The necessary information is selected for display on the display panel (for example, real time, fuel consumption, mileage, etc.) by means of the indication mode selection tool 19, and the reading of information from archives is provided by external devices with different degrees of access (via port 12 or modem 18 )

Information is displayed on the monitor screen of an external device in the form of a graph of changes in the level or fuel consumption in the fuel tank, vehicle operating modes and its geographical coordinates. Moreover, the vehicle operating modes are displayed on the graph of the change in the level or volume of fuel in the tank in the form of a sequence of colored sections, the color of each of which is pre-programmed and limited by the time of registration of the occurrence of the next or corresponding event.

So curve A (figure 2) displays a graph of fuel consumption or fuel level in the tank versus time, colored sections on the graph limited by the time of registration of the corresponding events (t1, t2, t3, t4, t5, t6, t7, t8, t9, t10, t11) - vehicle operating modes, where:

- t1 - time of registration (storage) of the event "Power on or the ignition switch":

- t2 - time of registration (memorization) of the event "Engine Start";

- t3 - time of registration (memorization) of the event "Start of movement";

- t4 - time of registration (memorization) of the "Stop" event;

- t5 - time of registration (storage) of the event "Fueling";

- t6 - time of recording (storing) the event "Start of the engine";

- t7 - time of registration (memorization) of the event "Start of movement";

- t8 - time of registration (storage) of the event "Stop";

- t9 - time of registration (storage) of the event "Turning off the power or ignition switch";

- t10 - time of registration (storage) of the event "Fuel Drain";

- t11 - time of registration (storage) of the event "Parking";

- a segment limited by time t1, for example black, characterizes the parking mode (of a stopped vehicle) with the power turned off or the lock.

- the segment limited by the time t1-t2, for example, yellow, characterizes the parking mode (of a stopped vehicle) with the power turned on or the lock.

- a segment limited by time t2-t3, for example, in violet, characterizes the engine starting and idling conditions (with the corresponding fuel consumption rate on graph A in idle mode).

- the segment limited by time t3-t4, for example, green, characterizes the driving mode (with the corresponding fuel consumption on graph A in the driving mode).

- a segment limited by the time t5 -t6, for example blue, characterizes the fueling mode (level rise on graph A) with the power on or the lock turned on.

- a period limited by time t10-t11, for example, red, characterizes the fuel drain mode (level reduction on graph A) with the power or lock turned off and on.

In this case, the modes (events) during time periods t5-t6 and t10-t11 when the power is turned off or the lock can be displayed with a line of the same, for example, black color.

As noted above, to determine the geographical coordinates of the vehicle during the registration of an event, the signals of the receiver 17 GPS signals associated with the antenna 14 are used.

Thus, the application of the above new technical solutions provides not only the storage and display of visual information on the fuel gauge or display panel, but also the ability to directly (via port 12), as well as remote (wireless) read and display information on an external device fuel consumption, vehicle operating modes and such parameters as fuel drain / refueling with registration of the vehicle location in real-time coordinates and, with accordingly, data transfer to the enterprise ACS for operational control, archiving and additional analysis.

In this case, the use of the second (parallel) archive and access to it using a special code exclusively through the computer (server) of the enterprise ACS,

provides increased system reliability in terms of obtaining and maintaining reliable information. Moreover, by presenting information about the operating modes of the vehicle in the form of a sequence of colored sections on the graph of the change in the level or volume of fuel in the tank, the color of each of which is pre-programmed and limited by the time of registration of the occurrence of the next or corresponding event, operational reading of the entire amount of information is provided when minimize visual load on the operator.

Thus, through the use of the totality of the technical solutions described above, a significant expansion of the system’s functionality is provided while simplifying the operational control of fuel consumption and vehicle operating modes.
