In the remote teaching numerical control system, if the detected video and audio signals do not meet the transmission standard requirements, the time control module causes the main control system to display the prompt and alarm to activate the standby device; if the detection meets the standard, the previous transmission device is closed, and the system Start running the continuous transmission transmission device to realize automatic switching of the propagation signal.
The teaching information data is accessed, modified, deleted, and automatically sorted and adjusted in a predetermined time sequence.
The fault handling module is mainly used to process and monitor the fault data information transmitted by the transmitting equipment due to the fault interrupt. In the patrol monitoring of the transmission equipment carried out by the automatic monitoring system, if an abnormal phenomenon is found, the automatic monitoring system immediately starts the fault processing module and performs corresponding display processing, that is, prompting or alarming; meanwhile, when the signal quality of the signal vibration is not When the system standard requirements or signal interruption are met, the module starts the fault processing module by interrupting.
The automatic monitoring module can automatically monitor and detect the working status of each device of each transmitting system, including the working power, current, voltage, power and signal source, excitation power amplifier, standing wave ratio and other parameter data of the device. If any of the above data does not meet the operating standards of the device, the module automatically enters the fault detection state.
The module has the function of proofreading and correcting the parameter data; controlling various working states such as automatic opening/closing of the transmitting device, and realizing automatic conversion of the standby transmitting device when the standing wave ratio parameter is greater than 1.2. Whether the various parameter data detected meets the standard status requirements of the system needs to be determined according to the specific quantity standard of the parameter data and the specific working state and standard of the transmission device.
