The major activity assurance command control system according to claim 1, wherein the communication-allowed signal class is a signal class which has been entered into the management scheduling unit before the start of signal detection and issued by the terminal authenticated by the management scheduling unit, and the communication-allowed signal frequency is a signal frequency set by the management scheduling unit according to the signal class;
the signal type and the signal frequency of the communication permission are not changeable in the signal detection period;
the sensing data transmitted from each type of sensing terminal that has been authenticated with the sensing data detecting unit is not modifiable within the signal detecting period.
7. The major activity guard command control system according to claim 1, wherein the sensing data transmitted from each type of sensing terminal authenticated with the sensing data detection unit is stored in the form of a sensing data list;
when the sensing data received by the sensing data detection unit is not in the data sensing list, the sensing data detection unit sends third notification information to the management scheduling unit.
8. The major activity assurance command control system according to claim 1, wherein the management scheduling unit constructs signal detection links for each type of movable signal detection unit based on real-time signal detection, specifically:
the movable signal detection unit which performs position updating first is used as a signal detection intermediate node, and second notification information sent by the movable signal detection unit for signal detection is sent to the signal detection intermediate node and is forwarded to the management scheduling unit;
if the movable signal detection units do not send the second notification information, selecting the movable signal detection unit closest to the fixed signal detection point in the movable signal detection units, taking the movable signal detection unit as a signal detection intermediate node, sending the second notification information sent by the movable signal detection unit for signal detection to the signal detection intermediate node, and forwarding the second notification information to the management scheduling unit.
