Embodiment Construction

[0032] Specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0033] Such as figure 1 As shown, an embodiment of a coal mining machine monitoring system is disclosed. The coal mining machine monitoring system includes: a coal mining machine wireless controller 101 , a bracket wireless transceiver 102 , a downhole control host 103 , and an uphole computer 104 .

[0034] The coal machine wireless controller 101 is installed on the side of the coal shearer 105 and communicates with the coal shearer 105 . The wireless controller 101 of the coal mining machine can detect the coal mine through the bus communication mode (such as CAN bus, RS485 bus, etc.), or through the digital input port (normally open / normally closed), or through the analog input (voltage / current). The shearer operating parameters of the coal machine 105 (such as operation-related information parameters and specific sensor data). The operati...

Abstract

The invention discloses a coal mining machine monitoring system which comprises a coal machine wireless controller, support wireless transceivers and an underground control host. The coal machine wireless controller is connected with a coal mining machine in a communicating mode. The support wireless transceivers are connected with the coal machine wireless controller in a wireless communicating mode and receive coal mining machine operation parameters output by the coal machine wireless controller. The underground control host receives coal mining machine operation parameters output by the support wireless transceivers and directly issues a coal mining machine control instruction or uploads coal mining machine operation parameters to the ground. The support wireless transceivers are distributed in a support of a coal mine shaft, by means of radio frequency transmission, the coal mining machine moves in the operation process, a power cable also acts in a bent mode, by means of radio frequency transmission, the problem of communication interruption caused by moving of the coal mining machine can be avoided, and the problem of data transmission of the coal mining machine is solved.

Description

technical field [0001] The invention relates to a communication technology of a coal shearer, in particular to a coal shearer monitoring system and a monitoring method thereof. Background technique [0002] During the operation of the shearer, we need to know the relevant parameters of the shearer in time, but during the operation of the shearer, it is unrealistic, very dangerous, and not allowed to check the specific parameters closely. At present, there are mainly two types of data remote display and monitoring of coal mining machines: [0003] 1) The communication cable is laid separately, and the communication cable and the shearer power cable are laid in parallel. However, the communication cables are usually relatively thin, and together with the power cables, they need to move and bend along with the shearer, and they are easily broken, causing communication failure and inconvenient inspection. [0004] 2) Carry out power carrier communication through power cables. ...
