[0036] The monitoring module is connected to the electro-hydraulic control system of the full-face support and is used to send commands to a single or all electro-hydraulic controls. The real-time data of each single electro-hydraulic control is fed back to the monitoring module. The monitoring module is used to collect the connection status of the support controller, the connection status of the sensor, the connection status of the driver, and device data such as the pressure, stroke, and inclination of the electro-hydraulic control of the support. Each electro-hydraulic control feeds each data back to the monitoring module in the form of a tcp message;

Select the electro-hydraulic control of a single support or the electro-hydraulic control of the entire working face, send a self-check command message. After the electro-hydraulic control receives the message, each electro-hydraulic control hardware that receives it starts to execute the embedded self-check program and returns the inspection result to the monitoring module in the form of a message.

Each electro-hydraulic control returns each data to the monitoring module in the maintenance platform in the form of a TCP message, and the display module in the maintenance platform displays it in a digital graphical interface;

[0045] 3) Select the electro-hydraulic control of a single support or the electro-hydraulic control of the entire working face, send a self-check command message. After the electro-hydraulic control receives the message, each electro-hydraulic control hardware that receives it starts to execute the embedded self-check program and returns the inspection result to the monitoring module of the maintenance platform; the inspection contents are as follows:

[0046] Check for controller hardware failures, including over-limit of voltage and current, etc.;
