摘要
 在繁華的城市中，隨處可見擁擠的汽車在馬路上行駛。而那些公交車經常會出現這樣的現象，比如說前壓后攆，這樣既不能安全行車，又不能準時正點的到達站點，無形中影響了乘客的安全和時間性。而當人們為治理此問題靠人工來傳送信息，不僅浪費了人力，物力，還大大浪費了時間。為此，本次設計了一種產品，名為無線搖控打卡器。
 它是以單片機AT89C51為核心，此微控制器將對整個系統發出控制信號。在本次設計中，選擇了臺灣生產的PT2262和PT2272系列芯片做為發射接收裝置的芯片。此裝置的功能是：當車載發射端發出信號時，在主機一端收到此信號，并做相應的處理，把數據顯示并打印出來。
 用本裝置，可以顯示出公交車到達的時間和車次，用以控制公交車前壓后攆，保證公交車的正常行駛。既保障了安全，又保證了正點到達站點的時間。對乘客而言，不僅提高了安全系數，而且保證了一個準時準確的短途行程。

 Summary
In prosperous city, everywhere it is thus clear that the crowded automobile ups north route to drive in the street.But those buses usually will appear such phenomenon, for example , thus buses can't drive in the street safely,and can't arrive to the station on time , affected the passenger's  safety and time invisibly.But when people wonder to manage this problem that depending on the deliver by artificial information, not only wasted the manpower, material resources, but also wasted time consumedly.Hence, I designed a kind of product, named the lead-in control device.
It is to take a machine AT89C51 as the core, this MicroController Unit will control the signal which is sent out from the whole system.In this design, PT2262 and PT2272 series chips that made in Taiwan are used as to shoot the chip of receive the device.The function of the equip is:When the car send out the signal, the host receives this signal, and do the homologous processing, make the data printed out also.
Using this device, it displays time and the NO. of the bus , in order to control the buses, guaranteeing that the bus drives normally.Since guaranteed the safety, and then guaranteed arrive to the station on time.To the passenger, not only raised the safe coefficient, but also guaranteed an on time accurate and short way route of travel on time .
 
 
The key words:     AT89C51    MicroController Unit    lead-in control device.
