Embodiment
As shown in accompanying drawing 1 to 3, system involved in the present invention is by being arranged on restricting signal emitter 1 on highway, being placed in the velocity measuring device 2 on vehicle and being arranged on cash desk, highway gateway the data such as speed are read with the treating apparatus 3 of relevant treatment and formed.
Sender unit 1 is arranged at the speed limit prompting of expressway access and the prompting position that road speed limit changes; This device can continuously or be interrupted extremely short time certain limit transmission towards periphery speed limit signal; The speed limit signal sending comprises vehicle and corresponding speed limit numerical value.According to the unidirectional of highway, have a lot of social connections; The signal covering radius of sender unit 1 is set in 30-50 rice, guarantees to cover all tracks; But can not produce too much signal to other facilities around disturbs.
As shown in Figure 3,3 pairs of velocity measuring devices 2 for the treatment of apparatus write vehicle, speed limit numerical value, 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, carries out speed of a motor vehicle calculating according to the positioning signal of front and back input in this way; 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; After the processing such as described 22 pairs of navigation signals of signal processing unit amplify, frequency conversion, be input to CPU23, 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, when 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 to 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, judgement vehicle is in transport condition or slipping state; At vehicle, read the speed numerical value of the velocity vehicle device of vehicle own during in transport condition.During 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 4,3 pairs of velocity measuring devices 2 for the treatment of apparatus write vehicle, speed limit numerical value, 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, judges according to the positioning signal of front and back input in this way; 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, when 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 can not write yet, and communicates acquisition with it by the speed limit cue emitter of porch) can be written to velocity measuring device 2; When vehicle rolls cash desk away from, the information storing in reading speed measurement mechanism 2 storage unit 24, is calculated respectively highway toll and the hypervelocity punishment situation of toll amount and this vehicle of hypervelocity information notification by expressway tol lcollection unit, the hypervelocity punishment unit for the treatment of apparatus 3 according to this information.The information for the treatment of apparatus 3 porch writing speed measurement mechanisms 2 comprises the speed limit numerical value that car plate, vehicle toll vehicle information, speed limit vehicle information and entrance section are 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, when entering highway, is got velocity measuring device 2 (or being carried by vehicle itself) from cash desk, the treating apparatus 3 of porch is by the information writing speed measurement mechanism 2 with charging, testing the speed relevant; The information writing can comprise the speed limit numerical value that car plate, vehicle toll vehicle information, speed limit vehicle information and entrance section are corresponding with this vehicle.Also can adopt car plate, vehicle toll vehicle information hardness in the mode of 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, according to gps signal, determine that vehicle is whether in travelling, at vehicle, from vehicle, read the speed of a motor 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.
When 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.
Certainly, above method of the present invention also can be applicable to common highway hypervelocity monitoring; Main difference is that treating apparatus 3 is not arranged on source, gateway; The data that exceed the speed limit in the time of can certain enters to locate highway at this vehicle read, or, when carrying out the situations such as vehicle annual test, read; Thereby obtain the hypervelocity information of this vehicle.
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.
