Single-wire non-contact series-connection fixed inclinometry sensor system

Abstract

The invention discloses a single-line non-contact series fixed inclination measurement sensor system which comprises a driving acquisition unit, a current loop circuit connected with the driving acquisition unit, a plurality of magnetic rings arranged on the current loop circuit in a sleeving manner, and a sensor circuit for connecting the magnetic rings and an inclination measurement sensor, the driving acquisition unit is used for outputting a control signal and acquiring sensor data, the current loop circuit is used for transmitting the control signal of the driving acquisition unit and taking out a signal for sensing the sensor data in the magnetic ring, and the magnetic ring is used for sensing the control signal of the current loop circuit and transmitting the control signal to the sensor circuit; the sensor circuit controls the inclination measuring sensor to measure and is further used for collecting data measured by the inclination measuring sensor and transmitting the data back. The inclination measuring sensors are connected in series in a non-contact mode through a current loop circuit in a penetrating mode, the non-contact connection does not have the waterproof sealing problem of cable joints, the distribution distance between the sensors can be adjusted at random at the non-fixed position, and the flexibility and reliability of field application are achieved.
