Abstract
The invention relates to a wireless data receiver for outdoor environment monitoring and introduces a smart fan adjustment type temperature control power-down mechanism. Based on an acquired temperature detection result in a receiver housing, the on/off control of a circuit between a power acquiring end in a data output interface and a power acquiring end in a data output terminal is controlled through electrically controlling a circuit breaker. In the off state, the speed adjustment of a miniature fan is controlled through specifically designing an electrode-less fan speed adjustment circuit based on a hollow structure on the surface of the receiver housing. In this way, when the power supply is cut off in the high-temperature condition, the active heat dissipation is realized through the intelligent controlling process of the miniature fan. Therefore, even in the high-temperature condition, the circuit board of the wireless data receiver is not damaged at all. As a result, the service life of the wireless data receiver for outdoor environment monitoring is effectively ensured.
