The data storage module comprises a data memory and a data calling interface; the data storage is a mass storage system made up of numerous mechanical hard disks or other storable hardware. The data calling interface is connected with the data memory and the terminal equipment. And the law enforcement personnel call data through the terminal equipment to enforce law.
The method for locating an overspeed vehicle of the invention comprises the following steps:
(1) setting a vehicle speed limiting interval by law enforcement personnel;
(2) when the vehicle passes through the pressure sensor, the vehicle mass and the feature code lambda are obtained;
(3) calculating the speed of the vehicle when the vehicle passes through the induction coil group;
(4) judging whether the vehicle speed is within a vehicle speed limit interval or not;
(5) if the judgment result is yes, the next operation is not carried out;
(6) if not, the vehicle is judged as an illegal vehicle and recorded.
The vehicle speed measuring system firstly records the time of current transmission of different induction coils under the same characteristic code according to the characteristic code, and then obtains the vehicle speed according to the distance of each induction coil. The vehicle speed judging system compares the vehicle speed obtained by the vehicle speed measuring system with a vehicle speed interval preset by law enforcement personnel, and if the vehicle speed is not in the interval, a signal is sent to the signal receiving module; if the vehicle speed is within the interval, no signal is generated.
The specific method for positioning the overspeed vehicle of the invention is analyzed as follows: when the vehicle speed is measured, the induction coil group is started, when the vehicle drives through different induction coils with the same characteristic code, the time difference of generated current is utilized to obtain the time when the vehicle drives through the induction coil group, then the speed is obtained through the time and the distance, so that the judgment module is started after the vehicle speed is calculated, whether the vehicle speed is in a limited interval is judged by the judgment module, if the vehicle speed is not in the limited interval, a signal is sent to the signal receiving module, the signal receiving module preprocesses the received signal, the preprocessed signal is sent to the processing module after the signal is in the sensitivity of the processing module and cannot damage the processing module, the processing module processes the signal, converts the signal into data which can be identified by the photographing module, integrates the time and place data, and sends the integrated data to the photographing module; the camera module shoots the photo information, the time and the place information are sent to the compression module, the compression module classifies and compresses the photo, the time and the place information to generate compressed data, and the compressed data are finally sent to the data storage module.
As shown in fig. 2, wherein the second induction coil 2, the third induction coil 3, the fourth induction coil 4 and the fifth induction coil 5 are equidistant with a distance D. When the vehicle passes through the fifth induction coil 5, the fourth induction coil 4, the third induction coil 3 and the second induction coil 2 in sequence, the time is recorded as t5，t4，t3，t2. At this time, the corresponding average vehicle speed
Is composed of
Wherein the content of the first and second substances,
to avoid inaccurate speed measurement due to forced speed change of the vehicle during speed measurement, the speed v can be set1，v2，v3And when the absolute value A of each speed difference does not exceed the value x set by law enforcement personnel, v is taken as the average speed
V is the speed v of the induction coil measured for the first time when the value x set by law enforcement personnel is exceeded1I.e. by
A＝|va-vb|(a,b∈{1,2,3},a≠b) (2)
The induction coil group sends v to the judgment module, and judges whether to continue sending signals to the signal receiving module or not by comparing v with the value of the vehicle speed limit interval C, wherein the judgment condition is 0-1 logical judgment, and the judgment process is as follows:
wherein logic represents a judgment statement, and C represents a numerical value (km/h) of the vehicle speed limit section.
Wherein the vehicle speed limit interval is set by law enforcement personnel. For example, when the maximum speed per hour of a road segment is 80km/h, law enforcement officers can set the speed limit interval as [0,80], and when the vehicle passes through the speed measurement interval at 0-80km/h, the vehicle speed is in the speed limit interval, and the sentence logic is judged to be 0; and if the vehicle passes through the speed measuring interval at the speed of more than 80km/h, the vehicle speed is not in the speed limiting interval, the judgment statement logic is 1, and the vehicle is judged to be the illegal vehicle.
If the statement logic is judged to be 0, the signal is not sent to the signal receiving module, and if the statement logic is judged to be 1, the signal is sent to the signal receiving module continuously.
When the signal is continuously sent to the signal receiving module, the signal receiving module sends the signal to the processing module, the processing module sends the signal to the photographing module, the photographing module photographs the vehicle photo information, the photo information is sent to the compression module to be compressed, the compressed information is sent to the data storage module, and the data storage module stores the photo data.
