(5) DEVICE FOR CONTROL OF EQUIPMENT OPERATION

I

The invention relates to automation and computer technology, namely, to technical means for monitoring the condition and operation time of equipment, and can be used in the chemical, petrochemical, and other industries.

A device for recording time is a simple equipment that contains signal sensors, drivers that perform the functions of a data processing unit, counters that perform the functions of a random access memory, a pulse generator, a switch and a switch unit that performs the functions of a dial-in field.

The device automatically takes into account the time just for each equipment position and total. Accounting for time. Can be simply summed up for each reason only with human participation 11.

A disadvantage of the known device is that an air condition is provided.

the ability to record the time simply for any of the reasons only for the total for all equipment positions, does not take into account the time of just each equipment position for each reason; In addition, there is a high probability of a subjective error when taking into account simply because of the large amount of information (the amount of dial-up on the switch manually. These drawbacks reduce the accuracy of the known device. The closest in technical essence to the proposed device is sensors, outputs

15 of which are connected to the first inputs of the polling unit, the output of which is connected to the first input of the line unit, the first output of which is connected to the second input of the polling unit, the second

20, the output of the linear unit is connected to the first input of the information processing unit, the output of which is connected to the first input of the memory unit, the first output; 390 of which is connected to the second input of the information processing unit, the third input of which is connected to the first output of the synchronizer, the second output of which is connected to the second input of the memory unit, the third output of the synchronizer is connected to the second input of the linear unit, board, dial-up field switch 2. A disadvantage of the known devices is the high probability of introducing a subjective error and reducing the accuracy of the accounting due to the fact that the input of the reason is carried out by different people, mainly workers, terminological errors are possible when entering the cause; it may be difficult for the worker to determine the true cause of the shutdown; the input of the reason is carried out by personnel who may be occupied by more important operations, for example, during an emergency stop, due to which the time just before the input of the reason may be accounted for as the time just for another reason. In addition, the disadvantage is a large number of typesetting fields for inputting reasons (by the number of devices). The aim of the invention is to improve the accuracy of control and ease of use. The goal is achieved by the fact that the device for monitoring the operation of equipment j contains sensors whose outputs are connected to the first inputs of the interrogation unit, the output of which is connected to the first input of the line unit, the first output of which is connected to the second input of the interrogation unit, the second output of the linear unit is connected to the first the input of the information processing unit whose output is connected to the first input of the memory unit, the first output of which is connected to the second input of the information processing unit, the third input of which is connected to the first output ohm synchronizer, the second output of which is connected to the second input of the memory unit, the third output of the synchronizer is connected to the second input of the linear unit, the board, dial pad and switch, key, counter, delay element, 6inoK code comparison and pulse generator, the output of which is connected to the first inputs of the switch and the counter, the output of which through the code comparison unit is connected to the input of the pulse generator, which is connected to the fourth output of the synchronizer, the fifth output of which is connected to the key input and to the second inputs to mmutator and counter, the output of which is connected via a key to the input of the board and to the fourth input of the information processing unit, the output of the keypad is connected to the fifth input of the information processing unit, ation and to the input of the delay element whose outputs are connected to the inputs of the pulse generator and the key, the second the output of the memory unit is connected to the third input of the switch, the outputs of which are connected to the inputs of the pulse generator and the key. The drawing shows a block diagram of the device. Diagram of the device contains sensors. 1, polling unit 2, a dispatch console 3 "comprising a display board k and a dial pad 5 and a central unit 6 including a line unit 7, a synchronizer 8, an information processing unit 9, a memory unit 10, a pulse generator 11, a switch 12, a counter 13, key k, block 15 comparison codes, the delay element 16. The device operates as follows. Information about equipment operation is collected by sequential cyclic polling by polling unit 2 of sensors 1. Poll frequency is synchronized through line block 7 by synchronizer 8. In memory block 10, for each position of the monitored equipment, its zone consists of groups of cells. Zones are arranged in order of decreasing priority. Each group serves as an accumulator of time simply for a specific reason or equipment operating time. Synchronously polling sensors from memory block 10 sequentially selects information on a given position and enters information processing block 9, which receives signals about operation or simple equipment from the 7th block 7. When a work signal arrives, a unit is added to the selected number and the result is returned to memory unit 10 at the same place. If there is no signal, the number is returned to memory block 10 at the same place without a change. When a signal is received

a unit in the service cell is entered into the zone if the cells where the symptoms of the cause are stored are simply missing. In this case, a increment operation per unit is performed on the contents of the intermediate storage group. In the case of the presence of a unit in one of the cells of the signs of the cause, simply the increment operation by one is performed on the contents of the group corresponding to this reason. Cyclically, with a period that is a multiple of the sensor polling period, the synchronizer 8 issues a command pulse, through which the key Ti is closed, the counter 13 is reset to zero, the switch 12 is reset, and the pulse generator 11 is started. The pulses produced by the pulse generator 11 are summed up in the counter 13 and control the operation of the switch 12. The switch interrogates successively the service cells of all zones in the memory block 10. The presence of a unit in the service cell is perceived as a command pulse, which from the output of the switch 12 enters the control input of the key T and opens it, and also stops the generator 11 of pulses. At the same time, the number contained in the counter 13 and corresponding to the number of the equipment that received the idle signal, through the public key 1 is displayed on the display k and enters the information processing unit 9. If there is no unit detected in any service cell, the contents of counter 13 exceed the value of the number of monitored vehicles. This leads to the triggering of the code comparison unit 15, which stops the pulse generator 11. When a person acts on one of the elements of the dial field 5, each of which corresponds to a specific reason, the corresponding signal enters the information processing unit 9. According to this signal, the zone corresponding to the number received from counter 13 through the Tt key is selected from the memory block 10. Thus, the reason is achieved simply and the number of idle equipment. A zero is entered into the service cell of the selected zone, a unit is simply entered into the cell of the corresponding reason feature, and the intermediate group on the accumulator is added to the content of the group corresponding to the unit in the stopping cause cell. Thereafter, the intermediate storage group is zeroed out and the zone returns to the same place in the memory block 10. Further, after the element 16, which is necessary for performing the above-described actions, is triggered in the information processing unit 9, the key I is again closed and the pulse generator 11 is started. Further operation of the device occurs in the manner described above. As a result of the operation of the device. In block 10 of the memory, arrays of operating time are generated and simply for every reason for all positions of the monitored equipment that can be used for printing, on computer media or for other tasks.

The device can be implemented on standard elements of electronics and computing. The use of the device allows to increase the accuracy of control by centralizing the input of information for reasons simply in the hands of the most competent person, and the input of information is greatly facilitated by the automatic addressing of the cause. The increase in the accuracy of control of the operation; to eliminate the causes and facilitates the analysis of the equipment operation.
