Description
Technical field
The utility model belongs to the bus digital control system of bus control field, particularly a kind of electronlmobil.
Background technology
Along with social development, the car owning amount of China is increasing, and environmental pollution, energy shortage problem are also day by day serious.But current electronlmobil is also in continuation conceptual phase, the electronlmobil integral structure that present stage exists is all undesirable, and its reason is: complex structure, chassis is overweight, cost is high, power consumption is too large.The pond energy storage of electronlmobil vehicle mounted electric very little, is unable to undergo that diff, change speed gear box etc. are overweight, the waste of the too many structure that consumes energy, thereby causes electronlmobil mileages of continuation too short.And the complex structure of electronlmobil, but there are the relatively independent parts of multiple interaction, and vehicle environment is more severe, has very strong interference, and not high with the control reliability of analog quantity.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of bus digital control system of electronlmobil, solved the data exchange between numerous control and test, by less signal wire (SW), the various electronic machines on electronlmobil are coupled together by network, and improve the reliability that data are transmitted in network.
To achieve these goals, the utility model is by the following technical solutions:
A bus digital control system for electronlmobil, wherein, comprises main frame, driving control system for electric machine, battery management system, information communication system, engine installation cooling system and LCD liquid crystal display systems; Described draw together main frame, driving control system for electric machine, battery management system, information communication system, engine installation cooling system and LCD liquid crystal display systems are all connected through CAN bus.
As preferably, described driving control system for electric machine is connected with sensor actuating unit.
As preferably, described engine installation cooling system is connected with sensor actuating unit.
The beneficial effects of the utility model are:
The utility model collection Based Intelligent Control, acquisition of signal, data processing and be in communication in one, realtime control is good, has realized the effective integration of electric automobile whole intelligent control and multi-sensor information.Solved the data exchange between numerous control and test, by less signal wire (SW), the various electronic machines on electronlmobil have been coupled together by network, and improve the reliability that data are transmitted in network.The utlity model has stronger error correcting capability, be applicable to high-noise environment.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating below, or can from practice of the present utility model, be instructed.Target of the present utility model and other advantages can be by below specification sheets or accompanying drawing in specifically noted structure realize and obtain.
Accompanying drawing explanation
Fig. 1 is control structure block diagram of the present utility model;
Fig. 2 is communication interface circuit schematic diagram of the present utility model.
The specific embodiment
Below by specific embodiment, and by reference to the accompanying drawings, preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, the utility model comprises main frame, driving control system for electric machine, battery management system, information communication system, engine installation cooling system and LCD liquid crystal display systems.Main frame, driving control system for electric machine, battery management system, information communication system, engine installation cooling system and LCD liquid crystal display systems are all connected through CAN bus.Driving control system for electric machine, battery management system, information communication system, engine installation cooling system are connected with corresponding sensor actuating unit respectively.
Engine installation cooling system is for detection of signals such as water temperatures, oil temperature, oil pressure, startup fault, water temperature over-high/low.Driving control system for electric machine is for detection of signals such as voltage, electric current moment of torsion, power, rotating speed, motor status, the speed of a motor vehicle, electrical fault, accelerator pedal position, brake pedal position, clutch state, key signal, gears.Battery management system is for detection of signals such as SOC, cell pressure, battery current, battery temperature, battery charging/discharging, battery failures.
The CAN bus transceiver PCA82C250 that selects Phliips company, PCA82C250 is the interface between CAN controller and Physical layer bus, meets CAN international standard 15011898, it can provide differential transmittability and the receiving capability of bus.By the object of PCA82C250, be in order to increase communication distance, improve the moment antijamming capability of system, protection bus, reduces radio-frequency (RF) interference, realizes thermal protection etc.The highest communication speed that PCA82C250 allows can reach lMbps, and nodes can reach 110 nodes at most.It can make system have good opening and alerting ability, even if this CAN bus, in the situation that not requiring that all nodes and application layer thereof change any software and hardware, can freely increase or reduce controller node.
As shown in Figure 2, the integrated CAN controller of supporting CAN2.0A and CAN2.0B completely in C805lF040, independently message RAM can process 32 message object, each message object can be carried out sending and receiving filtering, high workload speed reaches 1Mb/s, can complete all functions of CAN bus protocol data link layer and application layer.The characteristic of C805lF040 becomes the good selection of CAN bus node microcontroller, thereby system does not need special CAN controller.
82C250 is the interface between CAN controller and physical bus, and it is that special-purpose CAN drives chip, and the differential sending and receiving function to bus is provided.In order to strengthen the antijamming capability of CAN communication, between energy disperser and CAN driving, designed photoelectric isolating circuit.That adopt is high speed optoelectronic isolating chip 6N137, and input also all adopts 5V with the power supply voltage of output.The interference causing for fear of power supply, CAN communications portion adopts independent DC-DC power module power supply simultaneously.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of claim scope of the present utility model.
