Abstract
A system and method for remotely locating a communication error support for hydraulic supports. The system includes a control panel, a support controller, a data converter, and two support drivers of the same type. Each support driver has two bus interfaces. The control panel transmits a control command to the data converter in a form of a WiFi signal. The data converter converts the WiFi signal into a message signal and transmits the message signal to the support controller. The support controller transmits the control command to the two support drivers, respectively. The support drivers transmit the command through CANH twisted pairs and CANL twisted pairs. When a bus for transmitting the command of a certain node has an error, the support controller calculates the fault node according to a formula and feeds back the fault node onto the control panel.
