The invention provides a temperature detection module, a drive control module and a vehicle-mounted air conditioner. The temperature detection module comprises a circuit substrate and a temperature detection circuit, and the temperature detection circuit is arranged on the circuit substrate. The temperature detection circuit comprises: a temperature sensor interface, wherein the temperature sensorinterface comprises a first group of interfaces and a second group of interfaces, and the first group of interfaces is suitable for being connected with a plurality of external temperature sensors; aplurality of paths of first magnetic beads which are arranged in parallel, wherein one ends of the first magnetic beads of any path are suitable for being connected with the second group of interfaces; and a plurality of current-limiting resistors which are arranged in parallel, wherein one end of any current-limiting resistor is suitable for being connected with the other ends of the corresponding first magnetic beads, and the other ends of the current-limiting resistors are suitable for outputting temperature signals detected by the temperature sensors. Interference signals can be preventedfrom being transmitted to the outside along the temperature sensors.
本发明提供了一种温度检测模块、驱动控制模块和车载空调器,其中,温度检测模块包括:电路基板与温度检测电路,温度检测电路设置于电路基板上,温度检测电路包括:温度传感器接口,包括第一组接口与第二组接口,第一组接口适于与外部的多个温度传感器连接;多路并行设置的第一磁珠,任一路的第一磁珠的一端适于与第二组接口相连;多路并行设置的限流电阻,任一路的限流电阻的一端适于与对应的第一磁珠的另一端连接,限流电阻的另一端适于输出温度传感器检测到的温度信号。通过本发明的技术方案,能够防止干扰信号沿着温度传感器传输到外界。
