Remote controller fault positioning system and mining intrinsic safety type remote controller

Abstract

The embodiment of the invention provides a remote controller fault positioning system and a mining intrinsic safety type remote controller, the system comprises at least three mining intrinsic safetytype remote controllers and controllers respectively corresponding to the mining intrinsic safety type remote controllers and used for controlling a hydraulic support, and each mining intrinsic safetytype remote controller comprises at least two communication modules and a UWB positioning label; the mining intrinsic safety type remote controller is used for enabling the corresponding UWB positioning tags to start to send UWB pulse signals when one or more communication modules fail; each controller is used for receiving the UWB pulse signal through the correspondingly connected UWB positioning base station and calculating the distance between the corresponding UWB positioning base station and the UWB positioning label; and the corresponding controller is used for calculating the positioninformation of the mining intrinsic safety type remote controller with the communication fault according to the calculated and received distances. According to the invention, the communication reliability and robustness of the system can be improved, and the accurate positioning of the faulted mining intrinsic safety type remote controller can be realized, thereby guaranteeing the safety of an operator and the like.

Description

technical field [0001] The invention relates to the technical field of mine communication, in particular to a remote controller fault location system and a mine intrinsically safe remote controller. Background technique [0002] For the current control methods of hydraulic supports, most of them are controlled by wires through the electro-hydraulic controller of the hydraulic support. Since the length of the cable is fixed and the controller can only be placed in certain fixed positions, the control distance is also fixed. , the control distance cannot be flexibly changed, and its control method is relatively simple. In addition, due to the short distance between the operator and the hydraulic support system when operating, the safety of downhole operation is poor. Of course, there are also a small number of wireless methods for control, but usually a single communication method such as WIFI or Bluetooth is used, which has poor stability and cannot track the operator in rea...

Problems solved by technology

[0002] For the current control methods of hydraulic supports, most of them are controlled by wires through the electro-hydraulic controller of the hydraulic support. Since the length of the cable is fixed and the controller can only be placed in certain fixed positions, the control distance is also fixed. , the control distance cannot be flexibly changed, and its control method is relatively simple

In addition, due to the short distance between the operator and the hydraulic support system when operating, the safety of downhole operations is poor

Of course, there are also a small number of wireless methods for control, but usually a single communication method such as WIFI or Bluetooth is used, which has poor stability and cannot track the operator in real time; Communication failure, and it is impossible to timely and accurately locate it, etc.
