Specific embodiment
With reference to the accompanying drawings and examples, further description of the specific embodiments of the present invention.Following embodiment is only
For clearly illustrating technical solution of the present invention, and not intended to limit the protection scope of the present invention.
As shown in Figure 1, the present invention is a kind of hazardous area fan safe working method, comprising:
S1: when sensor module 1 and controller module detect the variation of temperature, the variation and time change of gas concentration
When, steady and sustained electric signal is issued to main control module 3；
S2: the electric signal that the signal processing module 31 of main control module 3 receives sensor module 1 is sent to after being handled
CPU 32, CPU 32 carries out analysis comparison according to preset condition；
S3: if reach preset temperature value, gas concentration value or time, starting is issued to blower 6 by drive module 5 and is referred to
It enables, blower 6 starts, and starts to work；
S4: it if CPU 32 detects that temperature is more than early warning temperature, controls blower 6 and stops working.
Further, sensor module 1 includes temperature sensor 11 and gas concentration sensor 12, controller in step S1
Module includes time controller 2.
A kind of hazardous area blower activation system, comprising: sensor module 1, controller module, drive module 5, power supply mould
