Ems Backstage Maintenance Software Based On Delphi

In recent years, energy shortages and environment problems have attracted more attention by people all over the world. However, the use of electric vehicles is an effective means to solve these problems. At present, electric vehicles have been developed for it’s benefit of low energy consumption and low emission. The development of electric vehicles can be affected by the performance of the battery. In order to keep the battery being in good condition, it must be managed and controlled reasonably. A practical and effective energy management system (EMS) is designed in line with scientific concept to improve the quality and security of the battery pack. The achievement of the up-posting computer energy management system based on delphi is introduced in this paper. Due to the fact that delphi is easy to learn, powerful and widely used, delphi has become the best choice for many developers. Through analyzing serial communication method with the ActiveX SPComm in Delphi, it expatiates a way of serial communication software. This method is simple, reliable and easy to transplant, and it has higher application value.The main work of this paper:(1)The interface of the system has been designed which is one of the basic functions in this software. The system contains the data acquisition interface and the EMS settings interface. Additionally, the user login id-entity authentication function has been provided. Only after a successful login, the user can enter this system. In this way, the system data can be protected from losing.(2)The first thing is to solve the serial communication in the developing of data acquisition system. This paper takes data communication between PC and the microchop computers for example, introduces the serial communication method based SPComm.(3)The database system has been developed in this system, mainly used for data storage and data management. The data storage is mainly composed of the user data storage and the battery data storage.Experiment proved that the EMS can achieve good result.
