Abstract
The utility model discloses an automobile mileage pricing system comprising a brake system module and a pricing meter. The brake system module is connected with the pricing meter by a drive meter. Vehicle speed digital signals received from the brake system module are converted to pulse signals by the drive meter, and then transmitted to the pricing meter. The utility model adopting the structure has the advantages that the vehicle speed digital signals are acquired by the brake system module of a CAN-Bus system without arranging a vehicle speed sensor, so the cost is reduced; the close arranging positions of the drive meter and the pricing meter are convenient for wiring; the pricing system is convenient in use and has excellent effect.
Description
Technical field
The utility model relates to automobile technical field, particularly a kind of speedometer for automobile pricing system.
Background technology
Along with developing of automobile industry, increasing ECU (Electrical Control Unit) is used on car load.For the stability and the saving wire harness cost that improve car load, a lot of vehicles have all been introduced CAN-BUS (controller local area network) system.In the electrical equipment node of CAN, the brake system module possesses the acquisition function of vehicle speed signal on each, and the vehicle speed signal on the physical significance is converted to digital signal broadcasts in the CAN network.At present, vehicle speed sensor is housed usually on the taxi, the mileage fee register adopts the output of the simulating signal speed of a motor vehicle to carry out work, vehicle speed sensor is installed causes cost to improve, and increases operation.
The utility model content
Technical problem to be solved in the utility model is at the deficiencies in the prior art, to provide a kind of and avoid installing vehicle speed sensor to reduce the speedometer for automobile pricing system of integral vehicle cost.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of speedometer for automobile pricing system, comprise brake system module and fee register, described brake system module is connected with fee register by driving instrument, and described driving instrument will be transferred to fee register after will being converted to pulse signal from the speed of a motor vehicle digital signal that the brake system module receives.
Described driving instrument comprises signal transmitting and receiving module, main control module and impulse output circuit, the output terminal of described brake system module is connected with the input end of signal transmitting and receiving module, the output terminal of signal transmitting and receiving module is connected with the main control module, described main control module is connected with the input end of impulse output circuit, and the output terminal of impulse output circuit is connected with fee register.
Described signal transmitting and receiving module is made of chip U1 and peripheral circuit thereof, and the model of chip U1 is TJA1040.
Described main control module adopts chip U2, and its model is NEC0828.
The utility model adopts said structure, and have the following advantages: 1, speed of a motor vehicle digital signal is obtained by the brake system module of CAN-BUS system, and does not need to install vehicle speed sensor, has reduced cost; 2, the position and the fee register position of the installation of driving instrument are approaching, convenient wiring; 3, easy to use, respond well.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is a theory diagram of the present utility model;
Fig. 2 is the circuit structure diagram that drives instrument in the utility model;
In Fig. 1~Fig. 2,1, the brake system module; 2, fee register; 3, drive instrument; 4, signal transmitting and receiving module; 5, main control module; 6, impulse output circuit.
Embodiment
As Fig. 1~a kind of speedometer for automobile pricing system shown in Figure 2, comprise brake system module 1 and fee register 2, brake system module 1 is connected with fee register 2 by driving instrument 3, drives to be transferred to fee register 2 after instrument 3 will be converted to pulse signal from the speed of a motor vehicle digital signal that brake system module 1 receives.
Signal transmitting and receiving module 4 is made of chip U1 and peripheral circuit thereof, and the model of chip U1 is TJA1040.Main control module 5 adopts chip U2, and its model is NEC0828.5 pin of chip U1 insert the signal output part of brake system module 1, be connected to resistance R 1 between 5 pin of chip U1 and 6 pin, be connected to resistance R 2 between 5 pin of U1 and 7 pin, 4 pin of chip U1 are connected with 9 pin of chip U2 by resistance R 4,1 pin of chip U1 is connected with 10 pin of U2 by resistance R 5,8 pin of chip U1 are connected with 11 pin of U2, and 8 pin of chip U1 insert resistance R 3 back ground connection.3 pin of chip U1 insert 5V power supply, the 2 pin ground connection of U1.12 pin of chip U2 are connected with the base stage of the triode T2 of impulse output circuit 6 by resistance R 6, and the base stage of triode T2 inserts resistance R 7 back ground connection, and the two ends of resistance R 7 also are connected to capacitor C 1.The emitter of triode T2 inserts resistance R 8 back ground connection, and the two ends of resistance R 8 also are connected to capacitor C 2, and the emitter of triode T2 is connected with the base stage of triode T1, and the base stage of triode T2 is connected with the collector of triode T1, the grounded emitter of triode T1.The collector of triode T2 inserts the signal input part of fee register 2, and the collector of triode T2 inserts resistance R 9 backs and is connected with KL15a line (igniting meter lamp line).The brake system module 1 of CAN-BUS system possesses the acquisition function of vehicle speed signal, and the vehicle speed signal on the physical significance is converted to digital signal in the CAN network, broadcast, after signal transmitting and receiving module 4 receives speed of a motor vehicle digital signal by CAN_H line and CAN_L line from brake system module 1, handle that by main control module 5 digital signal is converted to pulse signal, by impulse output circuit 6 pulse signal is outputed to fee register then.This system converts thereof into mileage number behind the vehicle speed data of handling the CAN signal, guarantee that the pulse data that sends in the certain hour is corresponding with actual distance travelled number, and mileage number is presented on the fee register.This system has saved the installation of vehicle speed sensor, has reduced integral vehicle cost.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
