control, which is connected to the sensors of the accounting of vehicles, and with the block of reception of information, connected to the blocks of transmission of information on the loading and unloading of vehicles 2.

The known device does not allow efficient use of the transport and cargo handling facilities of the complex.

The aim of the invention is to increase the efficiency of use of equipment excavator-automobile complex, that is, expanding the functionality of the device.

This goal is achieved by introducing a rhythm setting unit, a loading and unloading schedule control unit and a route shaping unit, inputs from the vehicle metering sensors of the distribution unit, and a second output of the information receiving unit,

The 20 outputs of which are connected to the second inputs of the loading and unloading schedule control unit and the vehicle control unit, the output of which is connected to the third input of the information input unit, the second output of the information receiving unit is connected to the first input of the loading and unloading schedule control unit, which output is connected with the fourth input of the information input unit and the second input of the deviation calculator, the output of which is connected to the first input of the route shaping unit connected by the second input to the output information input unit, the route forming unit output is connected to the second input unit and displaying information to the traffic lights.

The drawing shows a block diagram of the device. It contains information display unit 1, connected to information input unit 2, which is connected to control parameters calculation unit 3, information receiving unit 4, connected to units 5 and 6 for transferring information about loading and unloading of vehicles. The distribution unit 7 is connected to the information input unit 2 and the rhythm setting unit 8 connected to the information receiving unit 4, to the vehicle load and unloading schedule control unit 9, which is connected to the information input unit 2 and the information receiving unit 4. The vehicle traffic control unit 10 is connected to the information input unit 2, the rhythm setting unit 8 and the deviation calculation unit 11 connected to the vehicle load and unloading schedule control unit 9 and to the route generation unit 12, which is connected to the information display unit 1 , block 2 of information input and traffic lights 13. The sensors 14 and 15 of the accounting of vehicles are connected, to the block 8 of the rhythm setting and the block 10 of the monitoring of the movement schedule of the vehicles.

The device works as follows.

Before starting work, the initial Data of the excavator-vehicle complex is entered into the input unit 2: the quantitative composition of the equipment of the complex, the average movement times of empty and loaded dump trucks. the speed and number of unloading points, the amount of rock mass prepared for excavation in each face, the priority of the faces was determined according to the speed, According to the data entered in the control parameters calculation unit 3 of the information input unit 2, the optimal variant of the distribution of actually existing vehicles by specific junction branches is determined. This information through the information unit 2 enters the distribution unit 7, in which the given vehicle distribution

 The mean values of vehicle traffic and the planned loading and unloading capacity determine the required frequency of their movement and the frequency of loading and unloading for each of the controlled branches. The unit 8 for setting the rhythm generates pulses, the frequency of which corresponds to the frequency of the transport

0 means and frequency of loading and unloading. In route formation unit 12, the average values of the traffic intensity for each of the controlled

5 branches and their priority. This completes the preparation of the device for operation.

As the loading equipment is ready for operation, the vehicle information transfer unit 5 transfers readiness signals, which are perceived by the information receiving unit 4 and fed to the information input unit 2 and to the rhythm setting unit 8. At the same time, from block 8, set the rhythm to the subtractive inputs of the

5 reversible counters of a vehicle traffic control unit 10 at a given frequency receive impulses that simulate a planned vehicle schedule. As vehicles arrive in the controlled branches, the impulses generated by the sensors 14 arrive at the summing inputs of the corresponding reversing counters of the vehicle traffic control unit 10.

5 vehicle accounting. The number of these impulses corresponds to the number of dump trucks delivered to each of the controlled branches, and the frequency of their followings corresponds to the actual traffic

0 funds in the branch. The difference formed in the reversible counters of the vehicle traffic control unit 10 is characterized by the deviation of the actual traffic intensity in

Similarly, the block 9 controls the schedule of loading and unloading. When this is the beginning of the reference pulses of a given frequency, coming from the block 8 task

mi 5 transmission of information about the loading of vehicles and received by the block 4 receiving information. The same blocks 5 form pulses arriving at the summing inputs of the corresponding reversible counters of the pulses of block 9. Their frequency corresponds to the actual loading schedule. The difference formed in the reversible counters of block 9 characterizes the deviation of the actual schedule of loading from the planned one. The difference in the deviation from the vehicle supply schedule and the deviation from the loading schedule, determined by the deviation calculator 11, characterizes the actual level of vehicle deficit (the loading frequency exceeds the vehicle supply frequency) in the controlled branches. In route formation block 12, the relative values of the level of transport deficit in the controlled branches are calculated by dividing the absolute values of the actual deficit by the corresponding planned values of traffic intensity. The branch number, where the calculated value is at its maximum, determines the direction of movement of the next dump truck. In case of equality of the values calculated by the route formation unit 12 with respect to the level of vehicle deficit for two or more branches, the next dump truck is sent to the branch with the highest priority. In this case, only one of the traffic lights 13 indicates the permitted direction of travel (green), and that is all. the rest, corresponding to how the branches are filled with a lower deficit level, prohibit the movement of vehicles (red). The starting point of the vehicle unloading schedule is the first signals from the vehicle accounting sensors 15. The unloading schedule starts from the first unloading signals from the unloading information transfer units 6. Subsequent signals of the same sensors 15 form the actual schedules of vehicles for unloading and for their unloading schedules. The value of deviations of actual traffic schedules of vehicles, loading and unloading from planned ones, generated by blocks 9 and 10, also goes to information input unit 2, where total deviations are monitored. When the established limits are exceeded by block 4, the initial values of the control parameters are recalculated. The recalculation is also carried out at the exit from the loading and unloading equipment fixed by the signals transmitted by the respective loading and unloading information transfer units 5 and 6 and received by the information receiving unit 4. All control parameters selected by 2.6 are fixed by the information display unit 1. The economic efficiency of using this device is determined by its technical advantages indicated above.
