In addition, the control box contains a relay, a capacitor and a time relay, the first input of the control unit is connected via the serially connected break contacts of the first and second relays and the closing contact of the first time relay is connected to the first winding terminals of the turnips time, the second input of the control unit is connected to the first winding terminal of the first relay and to the first output of the control unit, the first input of which through the closing contact of the second relay is connected to the first terminals of the time relay windings, which through the opening contact of the second relay Time is connected to the second output of the control unit, the third input of which is connected to the first output winding of the second relay, the second outputs of the relay and the time relay are connected to the common power supply bus. FIG. t shows the functional diagram of the device; in fig. 2 is the electrical circuit of the control unit; The device comprises the battery 1, the engine generator 2, the switch of which is the vehicle ignition key, the control unit 4, the power supply unit 5, the first 6 and second 7 sensors, the first of which records the operation, the engine beneath transport load, and the second under p. load when the working body of the vehicle is in operation, the first 8 and second 9 AND elements, the OR-NOT 10 element, the third AND element. 11, pulse generator 12, second 13 third 14 and fourth 15 memory blocks, first 16, second 17 and third 18 counters, first 19 ,. the second 20 and third 21 decoders, the first 22, the second 23 and the third 24 indicators, the first trigger 25, the delay element 26, the first pulse generator 27, the first memory block 28, the fourth counter 29, the fourth decoder 30, the fourth indicator 31, the second the trigger 32, the key 33 and the second driver 34 pulses. In addition, the designated outputs 35-38. 11 6 The control unit 4 contains a primary relay with a winding 39, an opening contact 40 and a closing contact 41.1, a second relay with a winding 42, an opening contact 43 and a circuit, a contact 44, a first time relay with a winding 45 to the closing contact 46, the second time relay with winding 47 and opening contact 48, condenser 49. Sensor 6 is installed on the output shaft of the vehicle speed box, sensor 7-- on the shaft of the working body of the machine unit. . Indicators 22-24 and 31 are located in the same package, which is installed on the instrument panel of the machine device for the purpose of constant monitoring. The entire electrical system of the device is made in a closed version with sealing plug connectors. The device operates as follows. When the ignition switch 3 is set to position 1 (g. 2), the oj of the accumulator 1 of the entire electrical equipment of the machine device (output 35) is turned on, and when the ignition key 3 is moved the position of the engine 3 (exit 36) and supplying voltage to the second input of control unit 4, which triggers its relay with a winding 39 held in the actuated state for the time it takes for the ignition key 3 to return from position 2 to position 1 and help of the capacitor 49, after which the relay Wits on self-blocking through the closed contacts 40, as well as to powering the power supply unit 5. After starting the engine, the power supply to the electrical part of the machine device comes from generator 2. When the engine is operating in the payload mode of the wl drive in the payload mode, the workpieces of the machine device are closed at the sensor contacts 6 or 7 and at the first inputs of the elements And 8 wsh 9 are single potentials, which allows pulses from generator 12 to pass from their second inputs to their outputs. Then single prtenchles arrive at the inputs of memory blocks 13 and counters 16 or 17,

and, from the outputs of the latter, information in binary code is converted by decoder 19 or 20 to decimal code and is fed to the inputs of indicators 22 or 23.

When two sensors 6 and 7 are not working at the same time, the engine is idling, and there are zero potentials at the two inputs of the element OR-NE 10, which causes the presence of a single potential at its inverse output. This leads to the release of the element 11 on the first input for the passage of pulses from the second input to its output from the generator 12. Further passage of the pulses is similar to that considered. In addition, the single potential from the output of the And 11 element changes the state of the trigger 25, and the single potential that has appeared at its direct output enters the input of the comparison element and the delay element 26. When the allowed engine running time in idle mode, installed on the latching element 26, is reached, a single potential appears at its output, which enters the driver 27, and from the last output - a single pulse with parameters similar to those generated by the generator 12 Further passage of the pulse to the indicator 31, counting the number of times for the set idle time, is similar to that considered. In addition, the pulse changes the state of flip-flop 32 and at its inverse output a zero potential appears that goes to the first input of the switch 33. The voltage on the power supply sources of the machine device — accumulator 1 and generator 2, is applied to the second input of this switch. from the inverse output of the switch 33 is fed to the third input of the block A, causing its relay to operate with a dimming 42. This leads to de-energizing the relay with winding 39, and with it the power supply unit 5, which ultimately de-energizes the relay with winding 42 as well as ignition coils {engine carburetor audio output 37) and to stop the latter. To stop the diesel or gas turbine engines in block 4, two more peiie times are provided with windings 45 and 47. The voltage on these time relays comes as a

When the time relay with winding 45 is triggered immediately, and releases with a delay for reliably blocking it through its own contact 46 after the time required for releasing the second relay. Modes of operation of both time relays are identical. it

Q allows, through normally closed time relay contacts 47, to energize the solenoid valve (output 38), which acts on the fuel shutoff in the fuel line,

5 which causes it to stop. After a time for which the time relay with winding 47 is set, it triggers, opens its contacts 48, removes power from the solenoid valve Q and remains in this position until the engine starts and the relay operates with the coil 39.

In the absence of a working device in the machine device, it becomes a vehicle, and the block diagram of the electronic unit is changed by removing the following elements (Fig. 1): sensor 7, element 9,

block 14, counter 16, decoder 20 and indicator 23, and the element OR NOT 10 is replaced with the element NOT.

In addition to the visual removal of information about the engine operating time in various modes from the indicators 22-24, as well as about the number of violations from the indicator 31, the device has the ability to collect fixed information in the pulse counters by connecting to the device a portable removal unit, information, for which the specified unit its inputs must be connected to the outputs of the counters 16-18 and 29.

In order to protect its circuitry from external interference, it is made in a closed version with sealing of all plug-in connectors.

The use of the device will allow a constant objective recording of the engine operating time in all modes on an accrual basis, as well as provide fuel savings by actively objectively automatically influencing the forced stop of the engine in the event of its inaccuracy. 711282768
