Monitoring system enabling post-obstacle-encounter monitoring area automatic filling

The invention discloses a monitoring system enabling post-obstacle-encounter monitoring area automatic filling. The monitoring system includes a monitoring module which includes a plurality of monitoring probes, a transmission module, a fault alarm module, a central controller which controls the monitoring module through the transmission module and controls adjacent monitoring probes to switch directions to monitor an obstacle-encounter area after receiving alarm information transmitted by the fault alarm module, and a terminal display which is used for receiving video data and displaying monitoring information. The plurality of monitoring probes are arranged in the monitoring system, and once a certain monitoring probe is destroyed or malfunctions, one of adjacent monitoring probes rapidly reacts and adjusts its position, and performs monitoring photographing on a preset monitoring area of the damaged probe at once, and records whether the monitoring probe is damaged artificially or the monitoring area changes or not at a highest speed.
