Embodiment Construction

[0019] in figure 1 Among them, the taxi meter based on the 430 single-chip computer consists of a single-chip circuit module, a power-down protection circuit module, a liquid crystal display circuit module and a photoelectric sensor speed measurement circuit module.

[0020] in figure 2 Among them, the 16-bit ultra-low power MSP430F149 microcontroller includes a clock module, timer A, timer B, serial communication interface, comparator, and multiple I / O ports. The timer of the single-chip microcomputer has a compare 3 capture mode. The working clock can be obtained by dividing the internal clock or an external clock. The timer works in the capture mode and set to rising edge capture to obtain the count difference of the main counter within the pulse period interval. value. In order to improve the anti-cheating ability of the system, pulse signals can be obtained from the input gear and output gear of the gearbox, and the program written according to the inherent gear ratio can c...

Abstract

The taxi meter based on 430 single-chip microcomputer is composed of single-chip microcomputer circuit module, power-down protection circuit module, liquid crystal display circuit module and photoelectric sensor speed measurement circuit module. The main body of the taxi meter based on 430 single-chip microcomputer uses a touch-type liquid crystal display instead of mechanical buttons, and uses MSP430F149 single-chip microcomputer as the core to realize parameter setting, state selection and multiple information display. It has the advantages of easy system update, anti-cheating measures, comprehensive billing by mode, stable and streamlined system, and low power consumption. The system is practical and reliable, can accurately display the information of the simulated car, and can be put into practical application.

Description

Technical field [0001] The invention relates to a taxi meter based on 430 single chip microcomputer. Background technique [0002] With the acceleration of urbanization, the demand for taxis continues to increase, and the types of taxis are gradually diversified; as drivers demand their own rights and interests, charging by mode is an inevitable trend for night departures and congestion waiting; rising prices and additional charges Changes in fuel costs have caused adjustments in taxi fares, but the taximeter calculation algorithm cannot be updated in time. The charging method and accuracy of the taxi meter are closely related to the interests of the driver and passengers. [0003] The design of the traditional taxi meter is to use ordinary LCD display and mechanical button control # mechanical keys are prone to failure after frequent use; the meter relies on hardware and is tampered with, and the pricing page information is single, which is not conducive to passenger supervision ...
