Description
Technical field
The utility model relates to a kind of ground induction coil knotmeter calibrating installation.
Background technology
Furious driving is the first cause of traffic hazard in recent years, and over-speed vehicles is because inertia is big, and required stopping is long between the stopping time, but time of driver's reaction is slow, in a single day so have an accident, loss that causes and injures and deaths are very serious.Drive over the speed limit in order to limit, law enforcement agency adopts various speed-measuring methods to punish severely the hypervelocity behavior.
The motor vehicle velocity-measuring system of China's use at present, its principle has the radar velocity measurement principle, the ground induction coil measuring principle, laser velocimeter principle etc., wherein the automobile overspeed monitoring system based on the ground induction coil measuring principle has obtained widespread usage, mainly is because ground induction coil knotmeter antijamming capability is strong, the rate accuracy height, good reproducibility, cost is low.But the ground induction coil knotmeter also has a lot of shortcomings, for example: drift misalignment, wrong bat, calibration difficulties, wiring complexity etc.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: providing a kind of can test car speed, motor vehicle length, coil width, coil-span, and can finish at a distance the ground induction coil knotmeter calibrating installation of high-precision test.
Ground induction coil knotmeter calibrating installation provided by the utility model, comprise CPU (central processing unit), serial port networked unit, information display unit, keyboard, wireless transmission unit and ground induction coil tester, the ground induction coil tester is by wireless transport module and CPU (central processing unit) wireless connections, CPU (central processing unit) external connection keyboard, information display unit and serial port networked unit.Described CPU (central processing unit) adopts arm processor.Arm processor is connected with external keyboard, information display unit, serial port networked unit communication by its supporting external circuit and wireless transport module.The preferred LCD of information display unit.
Described ground induction coil tester is two ground induction coil testers independently mutually, and the ground induction coil tester contains the low noise relay of high frequency.The signal that tester is sent according to CPU (central processing unit) is finished corresponding action.
CPU (central processing unit) also connects electronics dot matrix large-size screen monitors by wireless transport module.Wireless telecommunications between electronics dot matrix large-size screen monitors and the CPU (central processing unit) can be known test speed and the time of demonstrating intuitively.
The beneficial effect that the utility model had is: 1, owing to used wireless transmission unit, realized the wireless transmission between CPU (central processing unit) and ground induction coil tester and the electronics dot matrix large-size screen monitors, avoided long complicacy and limitation apart from line.
2, owing to be provided with serial port networked unit, expanded the range of application of ground induction coil knotmeter calibrating installation, can make the test result of ground induction coil knotmeter calibrating installation and data upload in the computer of networking, carry out secondary treating or data analysis.
3, selecting keyboard for use is that CPU (central processing unit) is set test parameter, has made things convenient for the user to carry out real-time artificial parameter setting according to test case, has increased the application flexibility of ground induction coil knotmeter calibrating installation.
4, owing to used electronics dot matrix large-size screen monitors, can make the tester clear, observe test speed intuitively, made things convenient for electronics to take pictures and data recording.。
