Abstract
The utility model discloses a magnetoelectric sensor with encoding and encrypting functions for a price-marking instrument of a taxi. The utility model is composed of a main body which is provided with a rotating shaft, a transmitting circuit module which is arranged on the main body, and a receiving circuit module which is arranged in an instrument of an automobile. The transmitting circuit module is composed of a magnetoelectric converting circuit and an encoding transmitting circuit. The receiving circuit module is composed of a digital decoder and a drive circuit. The rotation pulse is encoded by the transmitting circuit module, and the rotation pulse is sent to the receiving circuit module by a cable; after an encoding signal is decoded by the receiving circuit module, the encoding signal can be output. The utility model has the advantages that the cheating phenomenon which is caused by the man-made reason can be effectively prevented, and the accuracy of the price-marking instrument can be improved.
Description
The utility model relate to automobile have the records of distance by the log the valuation usefulness magnetoelectric sensor, be a kind of automotive meter magnetoelectric sensor specifically with coding encrypting function.
The sensor that general taximeter uses is to utilize the magnet steel in the automobile kilometer flexible axle driving sensor to rotate the power variation that changes magnetic field, tongue tube or Hall element in the sensor are directly sent and the identical revolution pulse signal of flexible axle rotation, supplied with fee register and reach the purpose of having the records of distance by the log, valuating.Because the sort signal frequency is low, single, can be superimposed with other pulse signal easily, the artificial cheating because of the driver makes fee register produce wrong valuation, infringement consumer's interests easily.In order to prevent driver's artificial cheating, once the circuit in the sensor was done to improve, but effect is not satisfactory.
The purpose of this utility model be to provide a kind of can effectively prevent artificial cheating go out to hinder the sensor that the automobile fee register is used.
To achieve these goals, the utility model adopts following technical scheme: a kind of automotive meter magnetoelectric sensor with coding encrypting function, comprise the body and the automobile instrument that are provided with rotating shaft, it is characterized in that: it also has a control circuit, this control circuit is connected to form through cable by the receiving circuit module of being located at the transtation mission circuit module on the body and be located in the automobile instrument: the transtation mission circuit module is by the magnetoelectricity change-over circuit, the coding transtation mission circuit is formed, the magnetoelectricity change-over circuit is made up of magnetic induction part and the magnetic element that is installed in the rotating shaft, the coding transtation mission circuit is made up of digital encoder and transmitter driving circuit, magnetic induction part exports digital encoder to, digital encoder exports transmitter driving circuit to, and transmitter driving circuit exports the digital decoder in the receiving circuit module to; Receiving circuit module by digital decoder, driving circuit form, driving circuit connects to form through lead by transistor, resistance, digital decoder exports the transistor base stage to.
Good effect of the present utility model is: owing to take technique scheme, have only when number that the numerical coding circuit presets and digital decoding circuit in receiving decoding circuit preset digital identical the time, the digital decoding circuit just has output, so any abnormal signal that adds between coding circuit and decoding circuit, the capital makes the decoding circuit no-output, thereby has stopped the generation of people for cheating.Because the numerical coding circuit can be measured up to ten thousand numbers in advance, therefore, even identical cheating sensor in parallel, its probability of having an effect is also almost nil again.
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is the appearance structure synoptic diagram of a preferred embodiment body of the utility model;
Fig. 2 is the circuit theory diagrams of a preferred embodiment of the utility model.
See also Fig. 1, shown in Figure 2, the utility model is made up of the body 1 and the control circuit that are provided with rotating shaft 2.Control circuit is formed by being located at transtation mission circuit module 3 on the body 1 and the receiving circuit module of being located in the automobile instrument 4.Magnetic element P is housed in the rotating shaft, and rotating shaft is installed in the sensor body housing.Transtation mission circuit module 3 is tightened to one with sensor body 1 after sealing, transtation mission circuit module 3 links to each other with receiving circuit module 4 in being installed in automobile instrument by cable.
Sensor transtation mission circuit module 3 is made up of magnetoelectricity change-over circuit 31, coding transtation mission circuit 32.Receiving circuit module 4 is made up of reception decoding circuit 41, output driving circuit 42.By the magnetoelectricity change-over circuit 31 that magnetic element P and magnetic induction part IC1 (UGS3120) form, make magnetic induction part IC1 output revolutions pulse signal to digital encoder IC2 (VD5026).Coding transtation mission circuit 32 is made up of digital encoder IC2 (VD5026) and transmitter driving circuit IC3 (CD4011).The revolution pulse signal of 2 pairs of magnetoelectricity change-over circuit outputs of numerical coding IC circuit carries out encoding process, make it to change into a specific serial code signal, through transmitter driving circuit IC3 shaping, after the driving, transfer to receiving circuit module 4 interior forming by cable and receive decoding circuit by digital decoder IC4 (VD5028), when presetting in number that digital encoder IC2 (VD5026) presets and the Rcv decoder IC4 (VD5028) digital when identical, digital decoder IC4 (VD5028) is about to coding and solves, thereby recover original revolution pulse signal, via transistor T, output driving circuit 42 outputs that resistance R is formed." opening Lou " mode is adopted in output, can adapt to the connection requirement of various different automobile instruments.
The utility model adopts the automobile storage battery power supply.
