Description
Technical field
The present invention relates to electric vehicle engineering field, relate in particular to a kind of based on CAN fieldbus pure electric automobile intelligent instrument display terminal.
Background technology
Electronlmobil as a kind of transportation means of green in environmental protection, energy-conservation and driving performance aspect has advantages of that many internal-combustion engines vehicles are incomparable, along with the development of pure electric automobile technology and the raising of human oriented design, its electronic machine also constantly increases, if continue to adopt the mode of connection of point-to-point formula, to cause pure electric automobile electric wiring more and more longer, become increasingly complex, the weight of automobile constantly increases, thereby automobile energy consumption is improved, car load manufacturing cost increases, system operation reliability reduces, break down maintenance difficulty, in addition, it has higher requirement to information processing pure electric automobile, each electronic control unit will be processed a large amount of information and require information realtime interactive, therefore set up In-vehicle networking imperative.
Summary of the invention
The object of this invention is to provide a kind of pure electric automobile instrument display terminal based on CAN fieldbus, it has improved vehicle electric system reliability of operation, and the data interaction of operation Shi Ke real time information, has simplified automotive networking greatly, is easy to safeguard.
In order to solve existing problem in background technology, the present invention is by the following technical solutions: it comprises CAN module, process chip, serial ports, liquid crystal display, described CAN module is provided with CAN bus interface, CAN network interface, process chip interface, its process chip interface is connected with process chip, CAN bus interface connects CAN bus, CAN network interface connects automotive CAN network, and process chip is connected with liquid crystal display by serial ports.
The present invention is on the basis based on CAN bus application layer protocol SAE J1939, by CAN module, by CAN bus interface, read the real time data information of electronlmobil, via CAN module, be sent to process chip, process by analysis, from serial ports, send control command to liquid crystal display again, for showing the details such as the speed of a motor vehicle, rotating speed, electric weight, gear, bus current, bus voltage, failure code of pure electric automobile, and left and right turn signal, front according to country beam, front according to indicator lamp signals such as passing light, dangerous warning, braking during standstill, the system failures.
This equipment is owing to being directly articulated in CAN network, so, not changing original hardware design, only upgrade software in the situation that, can receive the information of transmitting in all CAN networks, and this is received, analyze, show, this has greatly reduced the structure design of pure electric automobile, in diagnostic procedure, do not need again the specific diagnostic tool of extra utilization, just can know any data of monitoring car load.
It can be articulated in the present invention in CAN bus as an independent node, and can the information on all CAN networks be analyzed, be understood, choose the needed amount of user, real-time is presented on LCDs, reliability and the real-time of instrumented data have been improved, and can be used as the car load diagnostic tool of pure electric automobile, and simplified greatly automotive networking, be easy to safeguard.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
