Example Embodiment
[0022] The invention discloses an online monitoring device for comprehensive state parameters of a rocker arm of a drum coal shearer, such as figure 1 As shown, it includes an intrinsically safe rocker arm vibration monitoring module, an intrinsically safe oil health monitoring module and an intrinsically safe pre-diagnostic center module.
[0023] The rocker arm vibration monitoring module and the oil health monitoring module are respectively used for online monitoring of the rocker arm vibration and the lubricant condition of the rocker transmission system, and they each communicate with the pre-diagnosis center module through wired communication and / or wireless communication. To communicate ( figure 1 In the illustrated embodiment, a wireless WIFI communication method is used) to transmit the collected rocker arm vibration and oil state monitoring data information to the pre-diagnosis center module. The pre-diagnosis center module receives these monitoring data information, and...
