  :; . ; ;

The invention relates to automation and computing and can be used in mining enterprises of mining chemistry, in enterprises of the mining and coal industries.

A known system for calculating the net weight of the fossil during its unloading from the mine trucks to the car dumpers, containing weight sensors, counters, an analog-to-number pulse converter code, automatic control unit and a digital typewriter ij. The lack of a device is the lack of possibility of separate weight accounting of performance by mining numbers. plots.

The known device gives a distorted estimate of the amount of material delivered by moving objects when accumulating several locomotive compositions in the zone of unloading points, which differ in the number of trolleys in the composition or in their carrying capacity. So, when passing through the loading station, installed before the loading points, the appropriate number of wagons will be recorded (their weight), and when passing through the receiving point, installed after unloading

. points of the next (other), Loco. the motives with a greater or smaller number of cars, in the composition, but in the vehicle there are failures in obtaining information (a different number of wahj rons will be recorded.). .

Of the known, the closest in technical essence to the invention is a device for measuring the productivity of mining sites,

15 contains the first and second weight sensors, the route sensor whose output is connected to the first register input, the OR element, the display unit, the first, second and third blocks of the AND elements, the weighing sensor, the output of which is connected to the first control trigger input, the output of which connected to the first input of the third block of elements And,

25 outputs of the second block of elements AND are connected to the first group of inputs of the first block of the OR elements and the second block of the OR elements, as well as containing the multiplication block, adders, de 30 Siphrator and encoder 2 J.

The disadvantage of the meteorological station is the lack of the possibility of a separate weight recording of productivity according to the numbers of mining sites, and in; Formation on the productivity of locomotive composition does not fully reflect the productivity of mining sites. In addition, trolleys are only weighed by reloading points with a constant tare weight (empty cars) being received without weighing the empty composition behind the unloading point. It does not take into account that in this near-barrel yard the number of unloading punches can be more than one, locomotive compositions can come with different numbers and types of trolleys, considerable sticking of minerals on the sides of the trolleys is possible (not all mountain mass is unloaded into the accumulator of the discharge point).

The operation of the device is based on the calculation of the net weight of the material delivered by the locomotive by subtracting the tare weight of the total weight.

At the approach of a loaded locomotive to the zone of unloading points at the output of the sensor. 1 shows the signal that goes to the first input of the state analysis unit 2. The second inputs of this block receive signals from the block of 3 sensors. Analyzing information from sensors of locomotive composition at unloading points, state analysis block 2 outputs 4 signals to one of the first inputs of the first block. The signals from the first outputs of block 2 determine which point (the left or right discharge point must be supplied with locomotive composition.

Then, the loaded locomotive train is loaded with the first weight sensor 5. Weight pulses through the corresponding element of the first block of 4 elements and arrive at the first input (addition tire) of one of the reversible counters of block 6. This counter summarizes the weight of the load delivered to the unloading points along with the weight of the container (trolley). Then the loaded locomotive is guided to one of the tippers 20 of the trolleys, where it is unloaded.

The calculation of the net weight of the material and the recording of the weighing results are performed when the locomotive composition leaves the emptying point. In this case, the state analysis unit 2, receiving information from the sensor unit nssichi, outputs to one of the corresponding inputs of the second unit 8 elements AND a signal. The signal coming from the second output of unit 2 corresponds to the state of the locomotive composition left from the left unloading station, and the signal received from the third output to the signal of the locomotive composition left the right unloading station.

Then, the sensor 19 of the route is triggered, at the output of which a signal appears that goes to the first input of the register 18, the output of which is connected to the second input of the display unit 17. The second weight sensor 10 is used to weigh the empty locomotive. Weight impulses

-through the corresponding element of the second block 8 elements AND, and through the first input of the first block 7 elements OR arrive at the corresponding Second input (subtraction bus) of the block 6 reversible counters. A reversible counter subtracts the tare weight (trolleys) from the weight previously recorded in it.

After the end of the weighing of the empty locomotive composition, the net weight delivered to the place of unloading of the material will be recorded in the corresponding reversible counter. From the sensor 14 of the end of the weighing triggers control 15,

5, the signal from which, will go to the fifth input of the third block of 9 elements I. Permission is given to overwrite the number c. the corresponding reversible counter on the weight indicator block 17.

0 Overwriting is effected by pulses from a generator of 12 pulses in the presence of corresponding signals at the inputs of the third block 9 elements I. At the same time, from one of the outputs of the elements of the block 9 elements I

5 signals are received at one of the second inputs of the elements OR of block 7 of the elements OR, by subtracting the number recorded in the corresponding reversible counter of block 6.

0

At the moment when in one of the reversible counters a zero number will be written, at the corresponding output of the block 11 elements OR there will be no signal, therefore

5, the rewriting operation of the reversible counter and the corresponding indicator of the weight of the indicator block 17 will be completed. As a result, it contains the recorded number corresponding to the net weight of the mineral.

The signal from the sensor 14 of the weighing end, in addition to the control trigger 15, also goes to the delay element 13, which, after

5, it is enough to display the true performance value of the mining areas in the display block 17, outputs a signal to the second inputs of the control trigger 15 and the register 18, setting them to the initial (zero) state. Simultaneously, the signal from the output of the delay element 13 is fed to the third input of the state analysis unit 2 5, resetting the output signal from the second or third output. The device is ready for further operation.

The state analysis unit 2 operates as follows. If there is a signal at the input of the element HE 21 and if there is a signal from the sensor 1 of the request to the first input of the element AND 33, the second trigger 24 will not be set to one, because its output will not have a signal from the first inputs of the first block of 4 elements I. At the same time, the first trigger 23 will be set to one.

When an unloaded locomotive departs from the unloading station, the signal arriving at the input of the element NOT disappears. The output signal of the element 26 on the cutout line is output. This output is the second output of the state analysis unit 2. When the signal from the Sergki element 13c1 arrives at the second and first inputs of the first AND 25 of the third element I-27, the signal for setting the first and second triggers 23, 24 is returned to the initial (zero) state at the output of the first element and 25.

At one of the first outputs, as well as at the second output of the state analysis unit 2, there are no signals.

If at the moment when there is no signal at the input of the element HE from the sensor 1 of the request 1 a signal is received, then the trigger 24 is set to one and its output signal is received at one of the first inputs of the block 4 elements I.

The operation of the state analysis block 2 for the circuits corresponding to the signal received on the other second input of the block is similar to that described above, with the only difference that the signal is at the corresponding first input of the first block. 4 elements And in accordance with only the presence of a signal at the third input of the second element And 32.

Thus, the proposed device can significantly improve the accuracy of accounting for the productivity of mining sites. Reliable information on the amount of mined or transported material is the main indicator of the performance of mining enterprises and a necessary element in regards to the automation of mining management systems. It is essential for preparing transportation, planning, analyzing, developing measures to improve organization, uncovering internal reserves for increasing the productivity of mining sites and other production processes. Improving the accuracy of accounting information about production indicators, it is possible to identify the causes of deviations of actual indicators of mining units from planned ones, forecast the possible situation with the plan and, therefore, ensure that operational decisions are made in the mining enterprise’s management system, the loss prevention production process.
