The invention relates to devices for controlling rail transport at unloading points with several entrances and exits, and can be used in mining enterprises of the mining and coal industries, as well as railway transport.

A device is known for controlling the distribution of locomotive composition at discharge points, containing an analyzing unit, to one output of which the scoreboard for the train sending / and to one and the other inputs are connected, respectively, sensors of inquiry and the presence of trains installed before the discharge points 11.

A disadvantage of the known device is the inability to obtain information about the state of the unloading points (to which unloading point to send locomotive composition and what kind of unloading point to go to it), which is necessary for separate weight accounting of the productivity of the mining areas, which can be done only with effective management taking into account the weight load of the compositions.

The purpose of the invention is to increase the efficiency of control by taking into account the load of each composition.

The goal is achieved by the fact that the control unit of locomotive composition distribution at the unloading points, containing an analyzing unit, to one output of which are connected the scoreboard of the composition, and to one and the other inputs, respectively, the sensors of the request and the presence of trains, installed before the unloading points, are equipped with the first inputs to other outputs of the analyzing unit by the accumulation unit of information on the weight of the unloaded material, weighing termination sensors and the route number connected to its second and third inputs, respectively, by a weight determination unit and a shaper for determining the net weight connected to the fourth and fifth inputs of the weight information accumulator, the output of which is connected to one of the inputs of the shaper for determining the net weight, the other inputs of which are connected with the outputs of the sensors of the presence of the composition, and the outputs with the third inputs of the analyzing unit.

In addition, the accumulation unit of information about the weight of the unloaded material consists of a generator, blockade | encryption and indication connected to one of its inputs by a register of route numbers, a reversible counter, triggers and logic elements OR and AND, the output of the first AND element connected to the inputs of the first an OR element connected by an output to another input of the decryption and indication unit and to one input of the second OR element, the other inputs of which are connected to the outputs of the second AND element, and the outputs to one input of the reversing An electrical device connected by its outputs to the third element OR, the output of which is connected to one of the inputs of the first element AND, the other and third inputs of which are connected respectively to the generator and one of the triggers, and the fourth and fifth inputs of the indicated element are the fifth inputs the weight accumulation unit, while the other inputs of the reversible counter are connected to the outputs of the third element AND, the first, second and third inputs of which are respectively the first and fourth inputs of the specified block, and the output of the second The game, whose input is connected to the input of the first one and is the third input of the weight information accumulation unit, is connected to one of the inputs of the route number register, the other input of which is the second input of the weight information accumulation unit, the output of which is the output of the decryption unit and indications. Figure 1 shows the functional scheme of the proposed device; 2 is a schematic diagram of the device; Fig. 3 shows the functionality of the weight information accumulation block diagram. The device (Fig. 1) includes an analyzing unit 1, the first outputs of which are connected to the departure board 2, and the other outputs are connected with their first inputs to the unit 3 of accumulating information about the weight of the unloaded material, the second and third inputs of which are connected respectively to sensor 4 termination in-zhivan and sensor 5 route number. The fourth inputs of the block 3 are connected to the weight block 6, and to the fifth - the driver 7 to determine the net weight. The output of block 3 is connected to one of the inputs of the shaping unit 7, the other inputs of which are connected to the outputs of sensors 8 for the presence of the composition, and the other outputs t to one of the inputs of block 1, to the other input of which the sensor 9 is connected. Block 6 includes travel sensors 10 and 11 (FIG. 2), and block 3 — weight metering unit 12, trigger 13 and delay element 14, the inputs are connected to sensor 4 for weighing ends. Sensors 9 and 10 are installed before unloading points 15 and 16. The analyzing unit 1 includes sequentially connected chains of elements HE 17-20, Elements I 21-24 and triggers 25-28. The outputs of the triggers 25 and 28 are connected to the detectors 29 and 30, respectively, included in the board 2. The inputs of the elements HE 18 and 19 are connected to the outputs of the sensors 8. The former 7 is also built on the logical elements HE 31 and 32, the elements And 33-36 and the triggers 37 and 38. Block 12 (FIG. 3) contains a block 39 of decoding and indication, to one and the other inputs of which are connected respectively the register 40 of the route number and the first element OR 41, the inputs of which are connected to the outputs of the first element AND 42, connected to the inputs of the second the element OR 43, the inputs of which are connected to the output The second element is And 44, and the outputs with one input of the reversible counter 4, the other inputs of which are connected to the outputs of the third element And 46, and the outputs to the third element OR 47, the output of which is connected to another input of the And element 42, the third input of which is connected to the generator 48. The inputs of the element 46 are connected to the element 20, the triggers 26 and 27 of block 1. The other inputs of the element 42 are connected to the elements 33 and 35 of the driver 7. One of the inputs 3jrieMeHTa 44 is connected to the sensor 11, and one of the inputs of the register 40 is connected to sensor 5. The device is operated following blowing way. At the approach of a loaded locomotive composition to the zone of discharge points | at the output of sensor 9, a signal appears that goes to the first (INPUTS of elements AND 22 and 23. When there is a signal at the input of the element HE 18, coming from sensors 8 of the presence of locomotive structures at unloading points (at the first unloading station 15 there is a locomotive composition, trigger 26 is not set to one, its output - there is no signal arriving at the first input of the weight accounting unit 12 and the second input of the element 21. At the same time, the trigger 37 is set It is a single state 1 @. The signal arriving at the first input of block 12 from trigger 26 corresponds to the state - to drive the locomotive to the first unloading station 15, and the signal to the second input of block 12 trigger 27 corresponds to the state - to drive in locomotive composition second unloading point 16. If there is no locomotive composition at the second unloading point 16, Tna input element 19 does not receive a signal from sensors 8 of the presence of locomotive composition at unloading points. As a result of the coincidence of the signals at the inputs of the element 23, the trigger 27 is set to one. The signal from its output goes to the second input of the block 12 and to the second input of the element 24, where it coincides with the signals from the HE elements 19 and 20 and sets the trigger 28 to the one state. The light indicator illuminates the signal allowing the locomotive to enter the second unloading station 16. The loaded locomotive composition is then weighed, fixed by the sensor 10. Signal pulses, proportional to weight, are sent to one of the inputs of block 12. The pulses of weight coincide with the signals received at the second input of the block 12, they are fed to their input (addition bus) of the reversible counter 45, which is in the weight accounting block 3. The weight of the cargo delivered to the unloading points along with the tare weight (wagons) is summed up. The loaded locomotive component is then guided to the tipper of the trolleys where it is unloaded.

At the moment the locomotive composition arrives at the second unloading station 1B, the input of the element NOT 19 receives a signal from the sensors 8. At the same time, the trigger 38 is set to one state, and the trigger 28 is set to the zero state. On the signaling device 30, the signal disappears allowing the locomotive to enter the second unloading station.

The calculation of the net weight of the material and the recording of the weighing results are done when the locomotive is discharged with an empty light from the unloading station. If, for example, the locomotive composition is sent from the second discharge point-16, the signal disappears at the second output of the sensors 8, which leads to the coincidence of the signals at the inputs of the element 35 and the appearance of a signal at the second input of the element 36 and at the third input of the weight metering unit 3.

Then, the sensor 5 of the route number is triggered, at the output of which a signal arrives at the input of the weight counting unit 3. The second sensor 11, included in the 6 g block, carries out the weighing of the empty locomotive composition. The pulses of weight, coinciding with the signals arriving at the third input of block 3, are fed to their input (subtraction bus) of the reversible counter 45, in the same way as in block 3. The tare weight (trolleys) is subtracted from the previously recorded weight.

After the end of the weighing of the empty locomotive composition, the net weight of the material delivered to the place of unloading is recorded in the reversible counter 45 of the block 3. From the sensor 4, the end of the move., A trigger 13 operates, the signal from which is fed to the input of the weight counting unit 3. Permission is given to rewrite the number from the reversible counter 45, located in block 3, to the weight indicator corresponding to the route number.

The signal from sensor 4, in addition to trigger 13, also goes to delay element 14, which, after a period of time sufficient to display the true value of the accounting indicators in the weight indicator, generates a signal arriving at the first input of trigger 13 and one of the inputs of block 3, sets the corresponding cells to the initial (zero) state. Simultaneously, the signal from the output of the delay element 14 is fed to the first inputs of the AND 34 and 36 elements, resetting the output signal from the element 35 and setting the trigger 27 to the initial (zero) state.

If at the moment when there is no signal at the input of element 18, a signal is received from the request sensor 9, the trigger 26 is set to one and its output signal appears at the first input of block 3. The device operates for circuits corresponding to the signal at the first input of block 3 accounting for weight, occurs as described.

The operation of block 3 is carried out in the following manner.

Weight pulses from sensor 10 through the corresponding element. And 46 (depending on the presence of signals at the first or second input), arrive at their first input (folding bus) of one of the reversible counters 45. This counter summarizes the weight of the load delivered to handling points along with tare weight.

When the locomotive composition leaves the unloading zone from the route number sensor 5, the first input of the route number register 40 receives information about the number of the unloaded locomotive composition, which is sent to the block 39. The second sensor 11 weights the empty locomotive composition. A signal proportional to the weight through the corresponding element 44 (depending on the presence of signals at the first or third input) and through its second input of logic elements 43 is fed to the corresponding second input (subtraction bus) of reversible counters 45. The counter subtracts the tare weight ( trolleys) from the weight previously recorded in it.

The signal from the trigger 13 is fed to the corresponding logic element 42. Permission is given to overwrite the number from the corresponding counter 45 to the weight indicator of the decoding and display unit 39. Overwriting is effected by pulses from generator 48 in the presence of corresponding signals at the inputs of logic elements 42.

At the same time, signals from one of the outputs of the elements 42 are received at one of the first inputs of the element OR 43, by subtracting the number written in the corresponding reversible counter 45.

. At the moment when a zero number is written in one of the reversible counters, there is no signal at the corresponding output of the OR 47 logic elements, therefore, the rewriting operation from the reversing counter to the corresponding weight indicator of the decoding and display unit 39 is over.

The signal arriving with element 14 delay on the second% of its register 40

route numbers set the latter to the initial (zero) state.

jRnoK 3 is ready for further operation. - i

Thus, the device eliminates the loss of information technological operations on the discharge points.

Using accounting information, it is possible at certain intervals to reveal the reasons for deviations of the actual production indicators of the mining enterprise from the planned ones, to carry out a forecast of the situation that is not fulfilled, not the plan and, consequently, the possibility of making appropriate corrections in the mine production management system.
