The embodiment of the invention discloses an on-off state detection circuit, a control method and a spacecraft. The on-off state detection circuit comprises at least two detection branches, an output port, a current-limiting resistor and a controller. The to-be-detected switches are connected with one ends of the detection branches in a one-to-one correspondence manner; the other end of each detection branch is grounded through a current-limiting resistor; the other end of each detection branch is electrically connected with the controller through an output port; each detection branch comprises an anti-backflow device and a load device, the anti-backflow device and the load device are sequentially connected between the switch to be detected and the output port, and the internal resistance of the load device of each detection branch is different; the controller obtains the port voltage of the output port, and determines the on-off state of each to-be-detected switch through the port voltage. The technical problems that in the prior art, due to the fact that a state judgment and function telemetering path is set for each single machine, the occupied space is large, the cost is high, and resource waste is caused are solved.

    本发明实施例公开了一种开关状态检测电路、控制方法和航天器,开关状态检测电路包括至少两条检测支路、输出端口、限流电阻以及控制器;各待检开关一一对应与检测支路的一端相连接;各检测支路的另一端通过限流电阻接地;各检测支路的另一端还通过输出端口与控制器电连接;检测支路包括防倒灌装置和负载装置,防倒灌装置和负载装置顺次连接在待检开关和输出端口之间,其中,各检测支路的负载装置的内电阻的大小均不相同;控制器获取输出端口处的端口电压,并通过端口电压确定各待检开关的开关状态。本申请解决了现有技术中对每一路单机均设置一条状态判断以及功能遥测的路径所存在的占用空间较大、成本较高且造成资源浪费的技术问题。
