Rwater≤Rminif so, the central processing module judges the information output logic of the condensation monitoring sensor to be '1', otherwise, the central processing module judges the information output logic to be '0'; wherein R iswaterRepresenting the resistance value of an inductive probe of a condensation monitoring sensor in the box body; rminIndicating the set minimum resistance value.
9. The substation cabinet monitoring system of claim 8, wherein the sensing portion further comprises: the displacement sensor is used for sensing the opening or closing information of the cabinet door of the box body; the transformer substation box body is characterized in that a first contactor A matched with the displacement sensor is arranged at the upper end of a cabinet door of the transformer substation box body, a second contactor B matched with the displacement sensor is arranged at the lower end of the cabinet door, when the cabinet door is closed, the output logics of the first contactor A and the second contactor B are 1, the central processing module judges the information output logics of the displacement sensor to be 1, when the cabinet door is opened, the output logics of the first contactor A and the second contactor B are 0, and the central processing module judges the information output logics of the displacement sensor to be 0.
10. The substation box monitoring system according to claim 9, wherein the central processing module performs logical judgment on the information of the small animal monitoring sensor, the wind speed monitor, the acousto-optic sensor, the smoke sensor and the condensation monitoring sensor transmitted by the signal concentrator by adopting an or logical judgment mode, when any one of the logical judgment output of the small animal monitoring sensor, the wind speed monitor, the acousto-optic sensor, the smoke sensor and the condensation monitoring sensor is 1, the central processing module analyzes and processes the received information and transmits the information to the operation and maintenance terminal and the alarm, otherwise, the central processing module discards the received information; when the central processing module judges the logic of the displacement sensor information transmitted by the signal concentrator to be 1, the central processing module issues an allowable information transmission instruction to the allowable execution module, and the allowable execution module is allowed to execute the allowable information transmission instruction; otherwise, the central processing module issues the locking information transmission instruction to the locking execution module, and the locking execution module executes the locking information transmission instruction.
