vani tvanspotnym spepptvam.

The following sequence is established.

Modes: automatic polling of objects, situation issue mode, optimal address issue mode. These modes form the cycle of the device. If necessary, after the end of the cycle, the remaining two modes can be formed. With the help of this device, sequential polling of information points is carried out, since information

obtained from objects equivalent, the formation of the operating modes of the device is carried out by the block 1 of the formation of modes, which is a combination of logic circuits.

In the register of 2 commands and numbers, information points are recorded under commands (mode) by a signal coming from block 1, and the number of the information point is formed by adding 2 units to the register, which enter automatically after polling the previous object from the output of pulse distributor 3 or from the control panel in the mode of individual interrogation or accounting through the block of formation of modes. The command code and the code number of the information point are read from register 2 through the switch 4 by the pulses of the distributor 3, controlled by the start-up and synphasing unit 5.

An information packet consisting of the command code, the code of the called object number and the strobe pulses through the OR 6 circuit and the receiving-transmitting unit 7 is transmitted via radio to the information.

6

Item points of 25 loading and unloading facilities. From the information points, operational or accounting information is read, which is transmitted via the communication channel to the transceiver unit 7 of the device.

Operational information refers to a message consisting of the situation code at the facility, the type of cargo and, for example, the number of the dump truck loaded or unloaded at the time of the inquiry of the information point. By accounting information is meant a message consisting of

numbers of dump trucks and the number of their loading or unloading at the relevant object. Each message consists of 10 information pulses with two overhead signals (strobe pulses) at the beginning and at the end of the message.

The code of the received operational or accounting information from the transmitting and receiving unit is fed to the input of the pulse selector 8 which allows to separate pulses of various durations by channels. Strobe pulses are fed to the input of control circuit 9 to start pulse distributor 10, and information signals through switch 11 are recorded using pulse distributor H to the corresponding bits of register 12, information from which is read by signal from pulse distributor 1O according to the types of messages into corresponding blocks: information about the situation at the facilities is read into block 13 of the situation at the facilities, information about the number of the dump truck - to the traffic control block 14, information about the type of cargo - to block 15 ects master account number transported rock mass (limestone, vskry .1sh).

After processing the information in the blot; 13-15, the result is displayed on the display unit 17 to monitor and record the operation of the mountain transport complex.

The device monitors the communication channel. For this, there is a transmission from each information point of two strobe pulses regardless of whether the message is received or not. From the first pulse, the distributor 10 is triggered and, from its first output, a signal is sent to the communication control unit 27, where a connection with this information point is signaled. Information from register 12 is also read into computational unit 16, intended for solving the problem of choosing op. the maximum route of dump trucks according to the criterion of the maximum profit of the pit. After polling the information points in the counter of the objects 19, the number corresponding to the number of objects polled in the system is recorded, the output from the decoder 20 receives a signal to the solution output in the decision output unit 18. After solving the problem of choosing the optimal route of the dump truck, the result is output from the computing unit 16 through a decision output block 18, an OR circuit 6, and a transceiver unit 7 to a pointer 26 of routes and situations. The device not only collects, stores and displays information, but also provides information on the situation to the operating personnel of loading and unloading objects, and outputting information about the situation at loading objects to unloading objects and information about the situation on unloading objects at loading objects. in the device using functional units 19-24. The state of the counter 19 of the polled objects, the output of which is received by the sigtal every time after the exit of the next object, is fixed by the decoder 20, the signals from the output buses of which are fed to the corresponding buses of the polling unit 24 and the logic circuit 21, the output of which signals go to the input of the control circuit 22 of the distributor pulses 23, intended for the distribution in time of the pulses arriving at the corresponding inputs of the logic circuits of the block 24. When the signals in time from the 2O decoder and pulse distributor At the respective inputs of the logic circuit of block 13, the situation is read in objects from block 13, and at the output of block 24, the code of the object number is generated on which it is transmitted. The issuance of object number codes and situation codes will occur when block 2 receives a pulse on mode formation block 1 and register situation 2 in the register 2, which will send the receive-transmitting block to information points 25 through the switch OR 6 and prepare them to receive the situation code for an object The object number code and the situation code are obtained through circuit 6 and the receiving and transmitting unit 7. to the route and situation indicator 26, as well as to information points 25. If a message about a temporary stop of loading (unloading) has come from the next polled object, then this message is urgently sent to unloading (loading) objects. In this case, the received message is recorded in the situation block at the facilities, and the signal of the received message from the output of the switch 11 enters the communication control block 27, where a pulse is generated that arrives at the mode generation block. The latter fills the counter 19 to the total number of simplified objects, the distributor 23 is started and the situation on the objects is output in the manner described. The considered interruption of the cycle of operation of the device allows the maintenance personnel of the mining equipment to accept radiation, based on the actual situation. In the next cycle, when the mode formation unit forms a command for automatic interrogation of objects, the device operates on a full cycle with the output of the optimal address for following dump trucks.
