Wherein the control instruction may be generated by a direct operation of an image projected on the in-situ debug host 200 by a worker, such as a click operation, an edit operation, etc.

In one embodiment, as shown in fig. 2, the wireless communication module 103 includes a power cat master cat and a power cat slave cat, wherein the power cat master cat is connected to the switch 102 and is disposed in a master control room in which the monitoring backend 100 is disposed; the power modem cat is connected to the power modem cat main cat and the in-situ debug host 200, respectively, and is disposed between devices in which the in-situ debug host 200 is disposed.
Specifically, the remote control module 101 and the switch 102 are both disposed in a main control room where the monitoring background 100 is disposed, and the local debug host 200 is disposed between devices, so that when the distance between the main control room and the devices is considered to be relatively long, the wireless communication module 103 performs receiving and sending of the image display signal and the control command, the signal transmission effect is poor, and therefore, the network coverage of a specific area can be realized by adopting the matched main cat and the sub cat of the power cat, so that the remote transmission of the signal is achieved.

Specifically, the monitoring background 100 may include a monitoring host 1001, and the remote control module 101 may include a KVM switch 1011, where the image display signal includes a sub-image signal, and the sub-image signal includes display information of a display screen of the monitoring host 1001. The first interface module of the KVM switch 1011 is connected to the monitoring host 1001, and the second interface module is connected to one terminal of the switch 102, so that the KVM switch 1011 receives the sub-image signal through the first interface module and transmits the sub-image signal to the switch 102 through the second interface module to transmit the sub-image signal to the wireless communication module 103 through the switch 102.

After receiving each sub-image signal through the wireless communication module 103, the local debugging host 200 can restore the display information on the display screen of each monitoring host 1001 according to each sub-image signal, so as to realize remote projection of the display screen of each monitoring host 1001. Specifically, the display screen of the in-situ debug host 200 may include a plurality of display areas for displaying display information on the display screen of each monitor host 1001, respectively, so as to realize remote projection of a plurality of monitor live displays.
