The beneficial effects of the utility model are: advantages such as the utlity model has and detect the accuracy rate height, response speed is fast, shock resistance is strong, failure rate is low, compact conformation, power consumption are little.
Description of drawings
Fig. 1 is the structural representation of the utility model motorcycle electric digital displaying meter;
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
See also Fig. 1, there is shown the structure of motorcycle electric digital displaying meter of the present utility model, comprise vehicle speed sensor 1, signal capture module 2, the speed of a motor vehicle and mileage display 3, PIC single-chip microcomputer 4, timer 5, fuel level sensor 6, voltage sensor 7, date time module 8.
During the work of motorcycle electric digital displaying meter, PIC single-chip microcomputer 4 sends control signal respectively and gives vehicle speed sensor 1, signal capture module 2, timer 5, the speed of a motor vehicle and mileage display 3; After vehicle speed sensor 1 receives the control signal of PIC single-chip microcomputer 4, gather the rotating signal of motor vehicle wheel, and utilize infrared mode to be converted into pulse signal and export to signal capture module 2; Timer 5 adopts the timer that is had in the PIC single-chip microcomputers 4, and length is 16, can define 0~65535 microsecond, after it receives the control signal of PIC single-chip microcomputer 4, and the recording timing time, and the result exported to described signal capture module 2; Signal capture module 2 adopts the signal capture CCP module of PIC16F877 single-chip microcomputer, after it receives the control signal of PIC single-chip microcomputer 4, catch the rising edge or the negative edge of the pulse signal of vehicle speed sensor 1 output in real time, receive timer 5 outputs with the corresponding timing signal of accumulative total pulse signal number, can calculate the speed of a motor vehicle and mileage by accumulative total pulse signal number and timing signal corresponding with it, signal capture module 2 is exported to the speed of a motor vehicle and mileage display 3 with the result.The speed of a motor vehicle and mileage display 3 adopt static multidigit eight hop count sign indicating number displays, and displacement realizes that data synchronization drives through 74LS164 by the SPI serial communication, after it receives the control signal of PIC single-chip microcomputer 4, will show from the signal output of signal capture module 2.
PIC single-chip microcomputer 4 also links to each other with fuel level sensor 6, voltage sensor 7, date time module 8, can show oil level, voltage, Time of Day information.Wherein, date time module 8 adopts the DS1302 real-time timepiece chip.
Above embodiment is only for the usefulness of explanation the utility model, but not to the restriction of the utility model protection domain.Relevant those skilled in the art; under the situation that does not break away from spirit and scope of the present utility model; can also make various conversion or modification, and the technical scheme that all are equal to should belong to also within the category of the utility model protection, is limited by each claim.
