Description

The invention relates to techniques for automating rail transport and is intended primarily for underground electric transport of coal mines.

A known method for automatically selecting the route of a mine train, which consists in fixing the volume of unloaded and arriving empty trolleys at loading points, comparing the latter with the amount of coal at loading points and distributing locomotives along routes.

The known method is carried out by a device containing sensors for monitoring the operation of the conveyor and working shift registers connected via a control unit with sensors for coal entering the hopper and the number of empty trolleys and with timers for stopping coal supply £ 1] ·

A disadvantage of the known method for automatically selecting the mine train route and device for its implementation is an excessive supply of empty trolleys at the loading point and significant time losses in anticipation of the destination of the mine train.

The aim of the invention is to reduce train downtime for each loading point.

The goal is achieved by the fact that for each loading point, the amount of coal in the bunker is measured and the amount of coal entering the bunker during the movement of the empty train to it, these volumes are summed, the volume of unloaded trolleys is subtracted from the received amount, the results obtained are compared for all loading points with each other and for the maximum result, choose the next route to the point.

The difference between the device for implementing the method is that it is equipped with an adder, a unit for selecting the maximum value and a route setting unit, the output of each of the coal intake sensors connected to the input of the corresponding shift register, and the output of each of the sensors for monitoring the operation of the conveyor connected to the input of the corresponding memory register, the paraphase outputs of the upper bits of the shift register are connected respectively to the inputs of the memory register, the output of which is connected to u which is connected to the input of the element input with Resp binary account snip, poslednego- output connected to one of the adder inputs, the other inputs of which. connected respectively to the output of the sensor for the number of empty trolleys and the output of the sensor for the supply of coal to the hopper of the loading point, and the output of the adder is connected to the corresponding input of the maximum value selection unit connected to the input of the route setting unit.

In FIG. 1 shows a block diagram of an automatic mine train route selection device; in FIG. 2, one of the embodiments of a device operation control unit.

The device contains information processing units 1, 2. and 3, one for each loading point, a common control side 4 connected to the inputs of the latter, the outputs of each of which are connected through the maximum value selection unit 5 to the installation unit 6. route a.

The hopper 7 of each loading point is combined with production lavas 8 and 9 conveyors 10-14, equipped with binary sensors 15 and 16, controlling the flow of lava 8 and 9. Conveyors 10-14 are also equipped with binary sensors 17-21 to control their work .. or stop .

Each conveyor line (for example, 10-11-12 or 10-13-14) connecting the hopper 7 of the loading point with the lava 8 or 9 corresponds to a shift register 22 | and a memory register 23. These shift and memory registers, one for each conveyor line, are located in the corresponding blocks 24-29. Each shift register corresponds to one of the pipelines, for example, p register 22 corresponds to the conveyor 12.

The outputs of the register 23 of the memory of blocks 24-26 are connected to the binary counter 30, and the outputs of the blocks 27-29 are connected to the binary counter 31, the outputs of which through the multipliers 32 and 33 are connected to the adder 34, the input of which is also connected to the coal volume sensor in the hopper 7 and a sensor for the number of empty trolleys.

Depicted in FIG. 2, the unit 4 for controlling the operation of the device contains a clock generator 37 connected via logic elements 38 and 39 AND to the delay element 40,

OR. In addition, the control unit 4 includes a one-shot 42 connected to a differentiator 43 and a second delay element 44, the output of which 15 is connected to a multiphase pulse series generator and to a third delay element 46.

The operation of the device according to the proposed method is carried out as follows about ₂₀ times.

The information processing blocks 1, 2, and 3 have the same structure and control the pulses from the control unit 4. The maximum value selection block 5 selects the following route — an empty train based on the information received from blocks 1, 2, and 3, and block 6 route setup implements teams ₃₀ to compose the route for the train with empty trolleys.

The hopper 7 of the loading point is connected to the lavas 8 and 9 by conveyors 1014. The cargo flow from the lavas 8 and 9 is controlled by binary sensors 15 and 16:

³⁵ freight traffic, not> the outputs of which signal 1 is formed if coal is supplied from the corresponding lava, and 0 otherwise. Such a representation of the cargo flow in this case ⁴⁰ is quite sufficient, since during periods of coal flow from the lava, the cargo flow can be considered constant (i.e., only the mathematical expectation is taken into account). Con ⁴⁵ fans 10-14 are equipped with sensors 17-21, at the outputs of which a signal 1 is formed if the corresponding conveyor is working, and 0 otherwise.

5 ° Each conveyor line connecting the hopper of the loading point with the lava (for example, 10-11-12 or 10-1314) has its own RAM - shift register 22 and memory register 55 23. So, the chain of conveyors

10-12 corresponds to a block 24 consisting of a shift register 22 and a memory register J23. Blocks 24-29 have the same structure. Each shift register corresponds to one of the conveyors of a given conveyor line (so, register 22 corresponds to conveyor 12). The capacity of each register is proportional to the time of transportation of coal by the corresponding conveyor. In each shift register, the paraphase outputs of the group of senior bits, the total length of which corresponds to the time of movement of the empty train from the near-barrel yard to this loading point, are connected to the inputs of the memory register 23 for each chain of conveyors 10-11-12 and 10-13-14.

The input of the shift register 22 is supplied with a signal from the sensors 15 and 16 of the cargo flows of the corresponding lavas. The shift clock pulses coming from the control unit 4 with a period equal to the time ₂₀ when the coal conveyor needed to fill one bit of the register is fed to the control inputs of all the shift registers, as a result of which the contents of the registers ₂₅ reflect the distribution in real time coal on conveyors 10-14, coming from the corresponding lavas 8 or 9. The bits of the memory register 23 at each moment in time are in the same state as the corresponding bits of the shift register 22.

In the case of a conveyor stopping from the sensor, for example, 19 Stop ₃₅ , the shift inhibit signal is sent to the corresponding input of the register 22. Thus, the distribution of coal is stored on a stopped conveyor 12.Od- _{4 {|} a time ban is imposed on reading information from the corresponding register 23 memory (the cessation of coal).

When a request is made for the route destination that appears at the end of the unloading of the train, a reset pulse is sent from the control unit 4 to the 0 binary counters 30 and 31 and the adder. Then, the control unit 4 receives the pulses shift the memory registers ⁵⁰ to the inputs on the series: the first shift pulse series reads information from the memory registers of blocks 25 and 26 in the respective binary counters 30 and 31, the second series ⁵⁵ reads Infor- mation from a memory register blocks 24 and 27 to these same binary counters, etc. At the end of reading from all the memory registers from the control unit 4, a pulse is sent to the control inputs of the multipliers 32 and 33, in which there is a conversion of the content 5 (of the press counters 30 and 31 into a code corresponding to the amount of coal on the conveyors 12 and 14 taking into account the productivity of lava 8 and 9, since the register discharge unit for lavas of different productivity has a different volume equivalent of coal. As a result, at the outputs of multipliers 32 and 33 there will be a code of the amount of coal that will come from the lavas' (8 and 9, respectively) into the loading bunker 7 points during the movement to this loading point of an empty train. These codes are submitted to the adder 34, in which the cargo flows from lavas 8 and 9 are summed up with the volume of coal in hopper 7 of the loading point coming from the coal sensor 35 in the hopper and subtracted trolleys located at the loading point and arriving at it, determined by the number of empty trolleys sensor 36. As a result, the adder code 34 receives the quantity of coal that will be in the bunker 7 of this loading point at the time of arrival at ozhnego composition, if it receives the traffic route to the loading point.

Similar codes are generated at the outputs of the adders of other loading points (blocks 2 and 3). All these codes are fed to the input of the maximum value selection block 5, which determines the number of the loading point with the maximum expected amount of coal in the bunker at the time the empty train arrives at it and transfers it to the route setting block 6.

The control unit 4 operates as follows (Fig. 2).

The clock generator 37 generates shear pulses, which through the protection device formed by the circuits AND 38 and 39, the first delay element 40 and the OR circuit 41, are fed to the input of the shift register 22 of all blocks 1, 2 and 3.

When asked for a route destination, the one-shot 42 generates a pulse of sufficient duration to implement the route selection procedure. The leading edge of this pulse by the differentiator 43 is converted into a reset pulse to 0 of the counters 30 and 31 and the adders 34. The pulse from the single-vibrator through the second delay element 44 is fed to the input of the multiphase generator 45 series of pulses, which sprinkles the shift pulses sequentially on each channel to the register input 23 memories of all blocks 24-29. After passing through the third delay element 46, the pulse from the single-shot 42 is fed to the control inputs of the multipliers 32 and 33. At this point in time, the multiphase pulse generator 45 ends its work.

Thus, the device continuously monitors the cargo flow from each lava 8 and 9 and remembers the amount of coal located on all conveyors 10-14 connecting the lava 8 and 9 with the loading points. When assigning a route to an empty train, not only the number of empty trolleys located at loading points and empty trains moving towards them is taken into account, but also the current coal volumes in the bunker 7 of the loading points and the amount of coal that enters the bunker 7 during the empty movement. ready to fly to these loading points. As a result, the number of the loading point is determined, in the bunker of which at the time of arrival of this empty train there will be the maximum amount of coal, and the empty train is immediately sent to this loading point.

Thus, the fleet of empty trolleys and ElectrovOzO'v is reduced, and the productivity of electric locomotive is also increased.

These shift registers and memory, one for each conveyor line, are located in the corresponding blocks 24-29. Each shift register corresponds to one of the conveyors, for example jp, the spin 22 corresponds to conveyor 12.

Depicted in FIG. 2, the device control unit 4 comprises a clock pulse generator 37 connected via logic elements 38 and 39 and to a delay element 40, which is connected to the input of the element 41 or. In addition, the control unit 4 comprises a single vibrator 42 connected to a differentiator 43 and a second delay element 44, the output of which is connected to a multiphase generator of a series of 45 pulses and to a third delay element 46. The operation of the device according to the proposed method is carried out as follows. The information processing units 1, 2 and 3 have the same structure and control the pulses 5 coming from the control unit 4, the Maximum value selection unit 5 selects the following route - the empty train based on information received from the blocks 1, 2 and 3, and the installation unit 6 the route is implemented by the teams for drawing up the route for the train with empty trolleys; the bunker 7 of the loading point is connected to the lanes 8 and 9 by the conveyors 1014. The traffic flow from lavas 8 and 9 is monitored by binary sensors 15 and 16: cargo traffic, the nS outputs of which signal I is generated if coal flows from the corresponding lava, and otherwise. Such a representation of the traffic flow in this case is quite sufficient, since during the periods of arrival of coal from the lavas, it is permissible to consider the cargo flow to be constant (i.e., only mathematical expectation is taken into consideration). Pipeline 30-14 is equipped with sensors 17-21, at the outputs of which a signal I is formed, if the corresponding conveyor is working, and O is otherwise. Each conveyor line connecting the bunker of the loading point to the lava (for example, 10-11-12 or 10-1314) has its own operational memory — shift register 22 and memory register 23. Thus, the chain of conveyors 10-12 corresponds to block 24, consisting of a shift register 22 and a memory register i23. Blocks 24-29 have the same new structure. Each shift register corresponds to one of the conveyor of this conveyor line (thus, register 22 corresponds to conveyor 12). The size of each register is proportional to the transportation time of the coal by the corresponding conveyor. In each shift register there are paraphase outputs of the group of senior bits, the total length of which corresponds to the time of movement of the empty train The near-barrel yard at this tipping point is connected to the inputs of memory register 23 for each chain of conveyors 10-11-12 and 10-13-14. To the input of the shift register 22 it supplies the signal of the sensors 15 and 16 of the traffic flows corresponding to the pressure. The clock pulses from the control unit A with a period equal to the transport time of the coal required for filling one register bit are fed to the control inputs of all the shift registers, S resulting in the contents of the registers reflecting the real time distribution of carbon pipelines 10-14, coming from the corresponding lavas 8 or 9. The bits of the memory register 23 are in the same state at each time as the corresponding bit of the shift register 22. In the case of stopping any co-fan from the sensor, for example, 19 Stop Control, a shift inhibit signal is sent to the corresponding IN. OOD register 22. Thus, the coal distribution on the stopped conveyor 12 is memorized. At the same time, the prohibition of reading information from the corresponding memory register 23 (termination of coal receipt) is imposed. When a request is made to assign a route appearing at the end of the unloading of the train, a reset pulse is sent from control unit 4 to O of binary counters 30 and 31 and the adder. Then, from the control unit 4, the shift pulses are fed to the inputs of the memory registers in series: the first series of shift pulses reads information from the memory registers of blocks 25 and 2b to the corresponding binary counters 30 and 31, the second series reads information from the memory registers of blocks 24 and 27 in the same binary counters, etc. Upon termination, the counters from all the memory registers from the control unit 4 receive a pulse to the control inputs of the multipliers 32 and 33, into which the content of the counters 30 and 31 is converted into a code corresponding to the coal volume on the conveyors 12 and 14 taking into account the capacity Lavas 8 and 9, since the register bit for lavas of different capacities has a different volume equivalent of coal. As a result, at the outputs of the multipliers 32 and 33 there will be a code for the volume of coal that will flow from the lavas (8 and 9, respectively) into the bunker 7 of the loading point during the movement of the empty composition to this loading point. These codes are fed to an adder 34, in which the cargo flows from lavas 8 and 9 to the volume of coal in the bunker 7 of the loading point, coming from the 35 carbon sensor in the bunker and subtracting the volume of empty carriages arriving on the black are summed up , determined by sensor 36, the number of empty trolleys. As a result, the adder 34 receives the code for the amount of coal that will be in the bunker 7 of this loading point at the time it enters the empty train, if it receives the route to this loading point. Similar codes are formed at the outputs of the adders of other loading points (blocks 2 and 3). All these codes are fed to the input of the maximum value selection unit 5, which determines the number of the loading point with the maximum expected amount of coal in the bunker at the time of arrival at the empty train and transfers it to the route set unit 6. The control unit 4 operates as follows (FIG. 2). The generator of clock impulses 37 generates shift pulses that, through the protection device formed by the AND 38 and 39 circuits, the first delay element 40 and the OR 41 circuit, arrive at the input of the shift register 22 of all blocks 1, 2 and 3. When requesting a route assignment, the single-shot 42 generates a pulse of sufficient duration to implement the route selection procedure. The front edge of this pulse is transformed by the differentiator 43 into a reset pulse into O counters 30 and 31 and adders 34. The pulse from the single vibrator 42 through the second delay element 44 is fed to the input of a multiphase generator 45 series of pulses sequentially through each channel. register pa 23 memory of all blocks 24-29. After passing through the third delay element 46, a pulse from the one-shot 42 arrives at the control of the inputs of the multipliers 32 and 33. By this Time, the multi-phase pulse generator 45 finishes its work. Thus, the device continuously monitors the traffic flow from each lava 8 and 9 and remembers the amount of coal located on all conveyors 10-14 connecting lava 8 and 9 to loading points. When assigning a route to an empty train, it is not only the number of empty trucks that are located at the loading points and empty trains moving towards them, but also the current volumes of coal in the bunker 7 of the loading points and the amount of coal that goes into the bunker 7 during the empty movement. ready to take off on these loading points. As a result, the measure of the loading point is determined, the maximum amount of coal will be in the bunker of that at the time of arrival of the front train, and the empty train is immediately sent to this load post. Thus, the park of empty trolleys and electrolysis cars is reduced, and also the productivity of electric locomotives is increased. Claim 1.
