Unit disaster control method and system

The invention relates to a unit disaster control method and a system. The disaster control system adopts an analog-disaster automatic alarm system, and the system comprises a processor, an acquisition module, an execution module and an early warning module, wherein the processor is respectively connected with the acquisition module, the execution module and the early warning module; and the processor carries out processing according to data acquired by the acquisition module, and judges whether an anomaly occurs and an abnormal type occurs, when the environment change value exceeds a certain range, the processor raises an alarm, if the environment change value is not developed, the processor stops raising the alarm, and if the change velocity continues to be accelerated, the processor controls an executing mechanism to take measures and controls the early warning module to make an alarm. According to the invention, the interferences of factors such as environmental temperature and humidity and the like can be significantly reduced, thereby greatly improving the reliability and stability of disaster control, and reducing the rate of false alarm; and the system is easy to use and low in maintenance cost.
