The invention discloses a safety detection device for vehicle axle counting and speed measurement. The safety detection device comprises a sensor A, a sensor B, a signal adapter and a track clamp. The sensor A and the sensor B are electrical vortex sensors, the sensor A and the sensor B are installed in the length direction of a track and connected to the signal adapter, the signal adapter is connected to a data processing unit of the system, the signal adapter is installed on the track clamp, and the track clamp is connected to the bottom of the track in a clamping way. Compared with the prior art, the safety detection device for vehicle axle counting and speed measurement is simple in structure, convenient to install, multi-functional, and low in price, and the safety detection device for vehicle axle counting and speed measurement has the following five functions: 1, system trigger starting; 2, train axle counting; 3, axle speed measurement; 4, judging the signal which shows that a vehicle is parked at the to-be-detected section and the like; and 5, two-way detection.
Description
technical field [0001] The invention relates to the field of axle detection, in particular to a safety detection device for automobile axle counting and speed measurement. Background technique [0002] In the existing railway safety detection equipment, it is necessary to use a series of signals such as trigger device, speed measurement, axle counting and whether to stop to monitor the status of passing cars, so as to use these signals to judge the start and stop status of safety detection equipment, axle speed and The number of vehicle axles is an essential process parameter in the state of railway safety inspection. However, in the existing measuring devices, the functions are not complete. To realize the measurement of the above parameters, one or more devices are usually required, which is costly, and the installation of multiple devices is complicated, and it is difficult to be uniformly compatible with the testing devices. Such as the patent application number 0382700...
