[Abstract]:A set of remote monitoring prototype system suitable for demonstration operation of new energy vehicle improves the function of the existing system, maintains its reliability and data integrity, and focuses on improving the real-time performance of the system's remote communication. It can provide data support for the demonstration and protection of new energy vehicles and related scientific research, and design an open on-board terminal architecture, which can form a sustainable development platform to provide support for related applications of vehicle networking. On the basis of tracking the development of remote monitoring system for new energy vehicles at home and abroad and briefly researching and defining the key technologies of Telematics, this paper first discusses the method of data acquisition and remote transmission. Then based on the local standards of Shanghai, the design requirements and architecture are put forward, and then the hardware and software implementation schemes of the vehicle terminal are designed and studied by using the structured design method. Finally, the performance of the prototype system is tested. In terms of the overall design of the system, a very open system architecture is proposed, and then the functional behavior and remote communication protocol (RCP) of the vehicle terminal are designed and described in detail. The high speed can based on SAE J1939 is adopted as the communication scheme with the vehicle control network, and the remote communication scheme based on CDMA 2000 EVDO mobile network is adopted. In the aspect of vehicle terminal design, the hardware implementation scheme based on MCU (STM32) is adopted, and the hardware circuit that meets the functional requirements of vehicle terminal is designed modularized. The software implementation scheme based on RTOS (渭 C / OS-II) is adopted. Firstly, the software architecture of vehicular terminal is presented, which has the characteristics of hierarchy and openness, and then the basic software component is designed and implemented by object-oriented method. Finally, the application software is designed in detail. The test shows that the prototype system has excellent data integrity and improves the real-time communication of the existing system.
