Takeaway:
In China, the taxi industry is an emerging industry in the early eighties, with the emergence of taxi, meter also emerged. But at that time, no company in the country could produce, so the meter was introduced from Taiwan. Taiwan is the main manufacturing site for meters, which now make 90 percent of the world’s meters. At present, there are hundreds of enterprises producing meters in China, mainly concentrated in Beijing. Shanghai, Shenyang and Guangzhou. In China, the economy is still in the stage of development. Due to the limitation of people’s living standard and road traffic, the ownership rate of private cars will not be greatly improved in the short term. Therefore, taxi plays an important role. The taxi meter is an essential instrument for the taxi. It is a special intelligent instrument for taxi transportation and charging. China’s first production meter enterprise is chongqing crane factory, the earliest meter all use mechanical gear structure, can only complete the simple meter function, can say that the early meter is a odometer. With the development of science and technology, the second generation of meter came into being. It adopts the combination of hand computer and mechanical structure to realize semi – mechanical and semi – electronic. At this point, it can also complete the work of valuation at the same time. The development of large-scale integrated circuits gave rise to the third generation of meters, which are all electronic meters. Its functions are constantly improving. When the single chip microcomputer appeared and applied to the meter, the model of the modern taxi meter is basically available, it can complete the meter, pricing, display and other basic work.
In the taxi is an important part of urban traffic, the health and development of the industry also get more and more attention. Car meter is the transaction criterion of both passengers and drivers. It is an important symbol of the development of taxi industry and the most important tool in taxi. It concerns the interests of both parties. The meter with good performance is very necessary for the majority of taxi drivers and passengers. Therefore, the study of automobile meter is also of great application value. Taxi meter can not only solve the problems of electronic system miniaturization, low power consumption, high reliability and so on, but also its development cycle is short, development software investment is less, especially for small batch, multi-variety products demand. Through the design of this topic, I can comprehensively use the learned digital system, C# language and other knowledge to learn the use of MyEclipse software editor and JDK software editor. Research content: Charging function can be realized according to charging standard. The meter is a tool used for fair trade settlement between taxi operators and consumers, so the accuracy of the meter valuation is directly related to the economic interests of both operators and consumers. According to the relevant laws and regulations of the state, taxi meter is included in the first batch of national compulsory verification of the work of measuring instruments, but also in recent years, the national quality and technical supervision department to strengthen the management of the six key measuring instruments. In the taxi is an important part of urban traffic, the health and development of the industry also get more and more attention. Car meter is the transaction criterion of both passengers and drivers. It is an important symbol of the development of taxi industry and the most important tool in taxi. It concerns the interests of both parties.

Conclusion:
With the development of economy, taxi has become one of the important means of transportation convenient for citizens, and it is closely related to our life. The development of taxi industry will certainly affect the development of the global economy and traffic, so we should pay more attention to the development of taxi industry and give innovation.
