Abstract

The utility model discloses an electric communication system of a pure electric bus based on a CAN (controller area network) bus, which comprises a whole bus controller, a data exchange unit, an information communication unit, and a monitoring unit. The data exchange unit comprises an oil pump power source, a gas pump power source, an air conditioner power source, and a direct current voltage converting module; the information communication unit comprises a battery management control module, a digital instrument, and a charger; the monitoring unit comprises a data collecting module, and a motor controller; and the whole bus controller is connected with the data exchange unit, the information communication unit, and the monitoring unit respectively through the communication cable of the CAN bus. The electric communication system of the pure electric bus based on the CAN bus has the advantages of respectively connecting the data exchange unit, the information communication unit and the monitoring unit with the whole bus controller through the communication cable of the CAN bus; three units are completely and physically separated; and the mutual data exchange of the three units is realized by the whole bus controller, thus greatly lightening the load factor of the controlling CAN bus, guaranteeing the instantaneity of controlling, and improving the driving safety of the electric bus.

Description

Pure electric coach electric telecommunication systems based on the CAN bus
Technical field
The utility model relates to pure electric coach, especially relates to the pure electric coach electric telecommunication systems based on the CAN bus.
Background technology
The eighties in 20th century, German BOSCH company has released serial data communications busses CAN in order to solve control system numerous on the automobile and the data communication between the detection system and resource-sharing problem.The CAN bus system is promoted in automobile industry rapidly, and in order to implement the standardization effort of bus protocol, AAEE (SAE) has formulated the J1939 agreement that is adapted to load-carrying vehicle and motor bus based on the CAN bus, is widely used.Because internal-combustion engines vehicle and electric automobile are in the difference of control structure, the CAN bus protocol of successful Application can not be indiscriminately imitated on the electric automobile on the traditional combustion engine automobile, and is stricter to the requirement of CAN bus communication system simultaneously.
Summary of the invention
The utility model purpose is to provide a kind of pure electric coach electric telecommunication systems based on the CAN bus of the CAN of reduction bus load rate.
For achieving the above object, the utility model can be taked following technical proposals:
Pure electric coach electric telecommunication systems based on the CAN bus described in the utility model, it comprises entire car controller, exchanges data unit, information communication unit, monitoring unit; Described exchanges data unit pack oil scraper pumping source, air pump power supply, air-conditioning power supply, direct voltage modular converter; Described information communication unit comprises battery management control modules, digital instrument, charger; Described monitoring unit comprises data acquisition module, electric machine controller; Described entire car controller communicates to connect by independent CAN bus communication cable and exchanges data unit, information communication unit, monitoring unit respectively.
Described CAN bus communication cable is a Shielded Twisted Pair.
Described CAN bus communication cable is provided with the 120W terminal resistance; The contact of CAN bus communication cable is all by light-coupled isolation.
The utility model advantage is described exchanges data unit, information communication unit, monitoring unit are communicated to connect by independent CAN bus communication cable and described entire car controller respectively, therefore three unit physically isolate fully, its mutual exchanges data must could realize by entire car controller, so just make the load factor of control CAN bus alleviate greatly, guarantee the real-time of control, improved the traffic safety of electric motor coach.
Description of drawings
Fig. 1 is the circuit principle structure block diagram of system described in the utility model.
Embodiment
As shown in Figure 1, the pure electric coach electric telecommunication systems based on the CAN bus described in the utility model, it comprises entire car controller, exchanges data unit, information communication unit, monitoring unit; It is characterized in that: described exchanges data unit pack oil scraper pumping source, air pump power supply, air-conditioning power supply, direct voltage modular converter; Described information communication unit comprises battery management control modules, digital instrument, charger; Described monitoring unit comprises data acquisition module, electric machine controller; Described entire car controller communicates to connect by independent CAN bus communication cable and exchanges data unit, information communication unit, monitoring unit respectively.Described three CAN bus communication cables adopt Shielded Twisted Pair, and are provided with the 120W terminal resistance; All contacts of three CAN bus communication cables are all by light-coupled isolation; The 82C250 chip of PHILIPS is elected in the driving of three CAN bus communication cables as.
