The present invention provides a fixed crossing electron police shoot device, including a wide-angle camera, a vidicon, an embedded industrial personal computer, a floor sensing coil and a topomorph floor sensing detector; the wide-angle camera and the vidicon are accessed in the embedded industrial personal computer via interface, the embedded industrial personal computer has a control management module; the floor sensing coil outputs the signal to the topomorph floor sensing detector, the topomorph floor sensing detector analyses the coil sensing signal changes, and informing vehicle passing signal to the embedded industrial personal computer; the traffic signal is also accessed in the embedded industrial personal computer via a converter; when the red signal and the vehicle passing signal are present at the same time, the control management module of the embedded industrial personal computer controls the wide-angle camera and the vidicon collect digital pictures and video fram, and processing treatment after being packet. The invention improves the detecting ratio of the overspeed, running a red light, processing real-time offending detection, real-time shoot for the crossing vehicle, no laborer required.
