Velocity measuring device 2 comprises the formations such as antenna 21, signal processing unit 22, CPU23 and storage unit 24; Antenna 21 can receive the restricting signal that GPS and/or Big Dipper navigation signal, sender unit 1 send; In the time that entering into the signal cover of sender unit 1, vehicle can receive the signal that sender unit 1 sends; And can, in the place that has GPS navigation signal, receive at any time navigation signal.Signal processing unit 22 amplifies, is input to CPU23 after the processing such as frequency conversion navigation signal, and the processing such as restricting signal amplification are input to CPU23; CPU23 calculates the travel speed of vehicle according to the navigation signal of input, and the vehicle writing according to treating apparatus 3 filters out the corresponding speed limit numerical value of this vehicle; Travel speed is compared with speed limit numerical value, the speed of a motor vehicle, geographic position, the time that exceed speed limit numerical value are stored in to storage element.The concrete speed of operation measuring method of CPU23 is: according to the time interval of front and back two navigation signals that receive, the changing value of longitude and latitude, calculate the travel speed of vehicle.This kind of velocity vehicle device can be independent of vehicle; Realize loose combination with vehicle.In which, velocity measuring device 2 can carry out combination with existing Fare Collection System; Utilize existing rfid system.Cost is lower.Can realize contact to velocity measuring device 2 at expressway tol lcollection place connects; Can wipe processing to all information such as storage elements by treating apparatus 3; So that recycle.
As shown in Figure 3, treating apparatus 3 writes vehicle, speed limit numerical value to velocity measuring device 2, and then velocity measuring device 2 receives signal, judges whether signal is vehicle coherent signal; To select the speed limit numerical value conforming to vehicle to treat and speed of a motor vehicle comparison; Otherwise further determine whether positioning signal; Positioning signal in this way, carries out speed of a motor vehicle calculating according to the positioning signal of front and back input; The speed of a motor vehicle calculating compares with speed limit numerical value again; As hypervelocity, the information such as the speed of a motor vehicle, geographic position, time are written to storage unit 24.
In addition,, as another kind of structure, velocity measuring device 2 comprises the formations such as antenna 21, signal processing unit 22, CPU23 and storage unit 24; Antenna 21 can receive the restricting signal that GPS and/or Big Dipper navigation signal, sender unit 1 send; Described signal processing unit 22 amplifies, is input to CPU23 after the processing such as frequency conversion navigation signal, and the processing such as restricting signal amplification are input to CPU23; Whether the geographic position that CPU23 calculates vehicle according to the navigation signal of input changes, in the time that changing, geographic position reads the speed numerical value of vehicle itself, and the vehicle writing according to treating apparatus 3 selects corresponding speed limit numerical value to compare with speed numerical value, the speed of a motor vehicle, geographic position, the time that exceed speed limit numerical value are stored in to storage element.This kind of structure, requires velocity measuring device 2 to realize and being electrically connected with vehicle, obtains the speed of vehicle.This kind of mode, the concrete speed of operation measuring method of CPU23 is: the latitude and longitude value of front and back two navigation signals of CPU23 basis, judges that vehicle is in transport condition or slipping state; Read the speed numerical value of the velocity vehicle device of vehicle own during in transport condition at vehicle.When this this kind of structure, velocity measuring device 2 is generally realized wireless information transfer with treating apparatus 3; Can be by the car plate of vehicle, vehicle information hardness in velocity measuring device 2; Remaining hypervelocity information etc. can be wiped processing by treating apparatus 3, to discharge storage space.
As shown in Figure 4, treating apparatus 3 writes vehicle, speed limit numerical value to velocity measuring device 2, and then velocity measuring device 2 receives signal, judges whether signal is vehicle coherent signal; To select the speed limit numerical value conforming to vehicle to treat and speed of a motor vehicle comparison; Otherwise further determine whether positioning signal; Positioning signal in this way, judges according to the positioning signal of front and back input; Determine whether vehicle location moves, if in mobile status, read the speed of a motor vehicle of vehicle; The speed of a motor vehicle is compared with speed limit numerical value again; As hypervelocity, the information such as the speed of a motor vehicle, geographic position, time are written to storage unit 24.
Treating apparatus 3, in the time that velocity measuring device 2 passes through expressway access, the information such as the speed limit in vehicle license plate relevant information and entrance section (entrance section speed limit also can not write, and communicates acquisition with it by the speed limit cue emitter of porch) can be written to velocity measuring device 2; In the time that vehicle rolls cash desk away from, the information storing in reading speed measurement mechanism 2 storage unit 24, calculates respectively toll amount and the highway toll of this vehicle of hypervelocity information notification and the punishment situation that exceeds the speed limit according to this information by expressway tol lcollection unit, the hypervelocity punishment unit for the treatment of apparatus 3.The information for the treatment of apparatus 3 porch writing speed measurement mechanisms 2 comprises car plate, vehicle toll vehicle information, speed limit vehicle information and the entrance section speed limit numerical value corresponding with this vehicle.This treating apparatus 3 is essentially the computing machine that is arranged on expressway tol lcollection place, and this computing machine is provided with expressway tol lcollection unit, hypervelocity punishment unit two system units, respectively vehicle is carried out toll calculating, is collected, and hypervelocity is punished.
Concrete example is as follows:
Vehicle, in the time entering highway, is got velocity measuring device 2 (or being carried by vehicle itself) from cash desk, the treating apparatus 3 of porch by with charge, test the speed information writing speed measurement mechanism 2 relevant; The information writing can comprise car plate, vehicle toll vehicle information, speed limit vehicle information and the entrance section speed limit numerical value corresponding with this vehicle.Also can adopt car plate, the vehicle toll vehicle information hardness mode at velocity measuring device 2.
When vehicle is during at running on expressway, velocity measuring device 2, according to gps signal, is measured the travel speed of vehicle; Or, determine that according to gps signal vehicle is whether in travelling, read the speed of a motor vehicle from vehicle at vehicle during in transport condition; The speed of a motor vehicle and speed limit numerical value are compared; If the speed of a motor vehicle and speed limit numerical value are greater than speed limit numerical value, by information storage such as this speed of a motor vehicle and corresponding time, geographic position (longitudes and latitudes) in storage element.
If along with travelling of vehicle, vehicle enters into the interval of different speed limits; The signal that velocity measuring device 2 sends according to the sender unit 1 receiving, replaces speed limit numerical value; So that the comparison of the speed of a motor vehicle and speed limit numerical value.
In the time that vehicle sails out of highway, treating apparatus 3 is by the information of contact or cordless reading cells 24; Thereby calculate the punishment situation that toll is used, hypervelocity should receive that should collect.
Be more than that specific description of embodiments of the present invention, but the present invention is not limited to foregoing description; In every case answer the equivalent transformation of aforementioned description gained; All should belong to protection category of the present invention.
