置。[Claims for Utility Model Registration] 1. Comprising a monitoring monitor device and a control unit, the control unit transmits a control signal to one or more display boards based on information from a higher-level station, and responds to this control signal. A display board control device that controls the display of each display board and controls the lighting of a monitoring monitor device based on a monitoring signal sent back from each display board. 2. The control unit compares the control signal sent to the display board with the monitoring signal sent back from the display board, and when the two match, displays on the monitoring monitor device and controls the display of the display board. The display board control device according to claim 1, which continues the monitoring control and outputs a failure alarm when the two do not match. 3. When the monitoring signal returned from the display board indicates at least one of the following conditions: on-site work, power outage, and failure of the display board, the control unit controls at least the display control and the monitoring control of the display board. A display panel control device according to claim 1, which separates one control operation. 4 The control unit sends a control signal to the display board, and then
A display board control device according to claim 1, which is a utility model and which determines that a circuit system including the display board is in failure if a monitoring signal is not returned within a predetermined time.
