| At present, there is a fairly high rate of oil losses during the transportation due to some uncontrollable (e.g. natural losses) and controllable (e.g. equipment, manual operation) factors. In recent years, losses caused by controllable factors become more and more with the rise of the oil price. These situations not only bring huge economic losses to oil companies, but also increase the difficulty in the management of oil distribution, quantity and quality. How to take care of the management of oil quantity and quality is becoming a common problem.The project "R & D of Oil Logistics Information Management System" in Xiamen Opson Technology Company is adopted as background in this paper which mainly research on vehicle management.It puts emphasis on the R&D of the vehicle monitoring terminal-—vehicle data recorder(electronic seal),which is my primal work in this project.Firstly, some basic technical words and relevant information are introduced, such as the technology of GPRS communication, short-distance wireless communication, CAN bus, and contactless smart card.Secondly, the system structure is shown up after function analyzed according to the current situation, which includes the scheme of vehicle monitoring terminal and MIS related.Thirdly, the hardware design of the vehicle monitoring terminal is described, comparing with the management flow and the communication protocol, based on which the vehicle monitoring terminal software is designed.Fourthly, the function and usage of MIS is introduced.In the end, the advantages and the disadvantages of the application are discussed, then some improvement proposals are risen.This system has been used in some sub-coporation of China Petroleum & Chemical Corporation.step by step, which is now in the preoperation stage. The situation shows that the system has achieved anticipated goal: good performance, high reliability, operation simply, definite information and so on. It is worth to be popularizing. |
