This invention discloses a three-dimensional electrical resistivity tomography (EDT) method for detecting cavities based on T-shaped electrode survey lines. A two-dimensional T-shaped electrode survey line advance detection observation system is constructed by deploying two mutually perpendicular survey lines (line 1 and line 2) behind the tunnel face. Electrode electrical resistivity data are collected for both vertical and parallel tunnels, and resistivity depth imaging maps are then established for each. The vertical imaging map determines whether the cavity is located to the left or right of the tunnel face, while the parallel imaging map determines whether it is located in front of or behind the tunnel face. This achieves preliminary two-dimensional planar positioning of the cavity. The detection space around the tunnel face is divided into target units, and through resistivity forward modeling and correlation calculation, correlation imaging results of each target unit are obtained. Ranges exceeding a threshold are delineated in the map, and combined with the preliminary positioning, the three-dimensional spatial location of the cavity is accurately determined, ensuring safe tunnel excavation.

The application discloses a kind of redundant methods, systems, readable storage medium and electronic equipment of entrance signal machine active transponder message, which contains: TCC sends route number information, route number corresponding head signal lighting state information and station equipment number information to TSRS;TSRS receives the information sent by TCC and sends it and temporary speed limit information to train on-board equipment;Train on-board equipment generates wireless train control curve in real time based on the route number information, route number corresponding head signal lighting state information, station equipment number information and temporary speed limit information sent by TSRS, combined with the route information called, and stores;When train runs to target transponder, if target transponder message is abnormal, and train on-board equipment successfully generates wireless train control curve in real time, train uses wireless train control curve in real time to enter route.Its advantages are: the method can effectively solve the problem of low operating efficiency caused by active transponder message sending exception.
