A tunneling convergence monitoring sensor

A tunneling convergence monitoring sensor belongs measurement. The present invention includes a tunnel convergence logger and microwave detection target of two parts, the tunnel convergence collection device comprises a microwave transmitter, microwave receiver. Microwave transmitter used to customize the target emission frequency of the microwave, including microwave signal transmission module (1), microwave frequency and bandwidth customization module (2), the angle measuring module (3); the microwave receiver for receiving customized frequency microwave signal, recording speed and time to go, converge computing, storage and data transfer, including microwave signal receiving module (4), microwave frequency customization module (5), time and speed measurement module (6), data processing and display module (7 ), data storage and transmission module (8). High data precision of the present invention, the convergence error of less than ± 1mm; from environmental constraints, real-time tracking can detect, measure the distance and data processing; improve efficiency, and ensure monitoring and construction safety.
