The invention relates to a locating system and a locating method of an infrared wide-angle communication synchronous integral type coal cutter which is used to determine the position of each hydraulic support inside the opposite working faces of the coal cutter inside a mechanized longwall face in the coal mine fully mechanized mining field. The coal cutter locating system comprises an infrared wide-angle transmitter and receivers, which are in communication connection. The locating method comprises the following steps: firstly, signal is sent out through the infrared wide-angle transmitter; secondly, each receiver obtains the received signal intensity value detected at the same moment by each receiver arranged on an adjacent support; finally, analysis is carried out according to the received signal intensity value to obtain the position of the infrared wide-angle transmitter relative to the receivers, thereby realizing coal cutter location. The locating system, which has a simple structure, has high interference immunity and accurate location during locating a coal cutter.
Description
technical field [0001] The invention relates to an infrared wide-angle communication synchronous integral type shearer positioning system and a positioning method for determining the position of each hydraulic support in the relative working face of the shearer in the mechanized longwall working face of the coal mine field. Background technique [0002] At present, most high-yield and high-efficiency mines adopt longwall coal mining. How to judge the position of the shearer on the working face is one of the necessary conditions for realizing automatic coal mining. In the existing infrared-based shearer positioning technology, an infrared emitting device is installed on the shearer, and a receiving device is installed on each hydraulic support of the working face. When the receiving device on the corresponding support receives the pulse signal, it is determined that the shearer has moved to the position of the support. [0003] In the current technology, since the infrared e...
