The Vehicle's Overload Recorder Of Road Passenger Transportation And Management System Software Research And Development

As our country's economy developping, the road passenger transportation occupies more and more parts of market, and the year rate of passenger transportation increases higher year by year. Eenterprises operating system reformed, and the drivers are vehicled by benefit, so it is common that the passengers are picked up on the way, or more people are picked up than the vehicle can bear in safe , though it is contrary. It is a great danger to the traffic operation that the accidents happen frequently. How to prevent effectively and record timely the overload of the road passenger vehicle? It has a great practical significance to strengthen management to the road passenger transportation safety, and standard driver's action. It is also useful to avoid serious accidents that are caused by overload, and analyze the reason if traffic accidents would happen.To explore a feasible way that warn timely and supervision about road passenger vehicle overloading is a part of this paper. The vehicle traveling data recorder can not record overload, so people want to achieve to warn timely and supervision about road passenger vehicle overloading by designing a independ system. The main chip of this system is C8051F020.This system can check password, set parameters about the system, judge the number of passengers up and down, record time and passengers'number, display the date and passenger's number, and so on. After improve the system, it can develop more functions on this vehicle traveling data recorder.To design software of the road transportation business management is another part of this paper. This system is developped by the VB6.0, and it's database is used by Microsoft Access2000. Its characteristic is artistic, friendly and easy to operate. Beside manage the daily cases in transportation business, it collects the passengers'number by lower position machine and transmits them to the transportation enterprise's management software center by RS-232, which is used to be a part of the road transportation business management software. This software system has achieved successfully. Besides the function that data can be taked off,its basic function has been realized,so it can be used in common passenger transportation business.
