The related equipment and facilities are the important guarantee to ensure the orderly production of the work, so it is necessary to do a good job in the protection of the relevant industrial equipment and facilities. If we want to do a good job in the protection of related equipment and facilities, we need to analyze and sort out the parameters of the equipment and facilities in the actual operation process in detail. In the industrial production equipment and facilities, the depth indicator plays an important role in it. If the depth indicator fails, most protective devices will not be able to protect. Therefore, in order to solve the above problems, it is necessary to set up the corresponding failure protection device or mode in the process of developing and designing the depth indicator, which can ensure the depth. The normal operation of the degree indicator.

In this process, it is necessary to use frequency conversion speed regulation technology, in the normal operation of the motor, the number of pulse signals collected by the encoder should be accumulated. If the data does not change, then the depth indicator does not work properly at this time, then the protection effectiveness will not be guaranteed. Once it is clear that the depth indicator does not protect, check the corresponding equipment facilities and check whether the corresponding equipment facilities have entered the crawling area. If you have entered the crawling area, the depth indicator will signal and process accordingly. If you do not enter the crawling area, the brake will be carried out in time, and then an alarm will be issued No.
