Abstract

The invention relates to devices for automatically recording the state of the downhole equipment of coal mines and can be used in information gathering systems for analyzing emergency situations. The purpose of the invention is to improve the accuracy of monitoring the emergency modes of operation of the downhole equipment. The device, using a digital ammeter containing an analog current meter 1 and an analog-to-digital converter 6, changes the current in phase 3 of the feeder 4 of the power supply drive 3 of the bottomhole machine. Then, using a controllable key.7, the obtained digital code is written into block 15 of registers 18. By inserting elements 8 and 11 and pulse-shifting circuit 16 of clock generator 9, the recorded code is shifted in block 15 of registers 18 from upper register 18 to the right. In the event of an accident, the contact of the alarm element 10 is opened and the filling of the information in block 15 is stopped. In the registers 18, the stored codes on the values of the currents preceding the alarms remain. 2 Il. i (L

The output of the current meter 1 is fed to the input 25 of the log in FIG. 2. The youngest, extreme analog-to-digital converter 6, whose information output is fed to the information input of the control key 7. The control input of the key 7 is outputted through the AND 8 element of the clock generator 9. The other input of the AND 8 element is supplied with the contact of the alarm element 10 opened in case of an accident on the downhole machine (it is manually returned). . The output element 8 is also wound on the element 11 of the delay, the output of which is fed to the pin 12 of the connector 13. Information multi-bit outputs of the key 7 through the contacts 14 of the connector 13 are fed to the information input of the block 15 of registers. Shift circuit 16 is brought out of lag element 11 through pin 12 of connector 13, and a code shift reversal signal can be sent via pin 17 (in the absence of this signal, codes between memory registers 18 are shifted from left to right, and if there is a signal from right to left) Unit 15 registers receives power from a source (not shown), 0 connected to the mains in the presence of electricity in it. In the event of a power outage, the unit 15 receives power from the power supply element 19 (the microaccumulator).

on the right, register 18 loses the code that it has to shift to the right, since it has nowhere to shift. Before the occurrence of the accident of the downhole machine, information about the instantaneous values of the codes consumed by the actuator 5 is accumulated in the memory B. At the time of the occurrence of the accident, the contact of the alarm element 10 opens, signaling the accident. From this moment on, the filling with information of block 15 is stopped. It contains the codes of instantaneous current values, which corresponds to the section D of the waveform that precedes the accident. Waveform plot E is lost, but it is not of interest for the analysis of the emergency mode.

After the accident, the module with block 15 is removed from the counterpart of the connector, 13. In this case, the block 15 is powered from element 19. The readout information of the preliminary section D of the oscillogram is produced in a computer on the surface of the mine (in the information processing center), where the module with the block 15 is inserted into the return part of the connector 13 of the computer interface and from it the reverse signal is sent to the contacts 17, and the contacts 12 receive pulses that shift information from the register to the register from right to left. computer

When writing data to block 15, each word is entered into high register 18 (from left to right through contacts 14

removes information from the older, leftmost, register 18.

Based on this information, the dynamic modes of the equipment are defined, which characterize the parameters and reliability resources of the bottomhole equipment.

In place of the removed module, another similar module can be inserted into slot 13, which is used as the previous one.
