Back board environment monitoring system

The backplane environment monitoring system, the environmental monitoring unit, a control unit and a connector constituting the alarm circuit; environment monitoring unit and a temperature sensor, respectively, and a fan connected to a voltage signal; temperature signal for acquiring the backplane, fan speed and fan voltage signal ; and all the collected signals transmitted to the control unit; and a control unit connected to environmental monitoring units, various signal transmission receiving environment monitoring unit, and the fan control voltage signal and / or alarm signal based on the output signal of the analysis results ; alarm circuit receiving the alarm signal from the control unit, the corresponding alarm actions. Using only an environmental monitoring circuit, so that the result of unified environmental monitoring, alarm solve the problem of inconsistency; under all conditions, may be controlled on the closed-loop control means; and, combinations alarm according to user needs can be flexibly transformed , easier to use.
