Abstract
The utility model discloses a controller area network (CAN) network router for an electric passenger car, and the CAN network router comprises an integrated circuit board, and a central processor, a power supply module, a global positioning system (GPS) module, a communication module and a plurality of CAN network interfaces, which are arranged on the integrated circuit board; and the GPS module, the communication module and the CAN network interfaces are respectively connected with the central processor. The CAN network router is a hub for the information exchange among multiple CAN buses, data which is interacted among different subnets is forwarded through the CAN network router, so that the load of the CAN bus can be greatly alleviated. By utilizing a traditional general packet radio service (GPRS) network resource, parameters to be monitored on the electric passenger car is uploaded in real time to a server to be stored so as to be convenient for users to inquire and analyze, so that the system operation and maintenance cost is greatly reduced, and technical guarantee is provided for the mass production of the electric passenger car.
Description
Technical field
The utility model relates to electric motor coach information of vehicles network and supervisory control system field, specifically a kind of electric motor coach CAN network router.
Background technology
Electric automobile relies on the advantages such as its energy-saving and environmental protection, noise are little in recent years, is progressively replacing traditional fuel-engined vehicle.Along with the development in pluralism of Hyundai Motor function, ECU (Electrical Control Unit) constantly increases in the car, and these ECU (Electrical Control Unit) all need then to be connected with the background monitoring center by the set of CAN bus, realizes the monitoring of information of vehicles.But the CAN bus is often more than one on the electric motor coach, and existing high-speed CAN bus has again low speed CAN bus.If all information are all merged into a CAN bus, can significantly increase the load capacity of CAN bus.
The utility model content
The technical problems to be solved in the utility model provides a kind of electric motor coach CAN network router, alleviates the problem of the load capacity of CAN bus.
The technical solution of the utility model is:
A kind of electric motor coach CAN network router comprises surface-mounted integrated circuit, is arranged at central processing unit, power module, GPS module, communication module and a plurality of CAN network interface on the surface-mounted integrated circuit; Described GPS module, communication module and the CAN network interface of being connected all are connected with central processing unit.
Be provided with two RS232 interfaces on the described surface-mounted integrated circuit, described GPS module is connected with central processing unit by a RS232 interface, and described communication module is connected with central processing unit by another RS232 interface.
Described CAN network router also includes display module and keyboard input module, and described display module and keyboard input module all are connected with central processing unit.
The number of described CAN network interface is three.
Described communication module is selected the GPRS module, is provided with the GPRS power module that is connected with the GPRS module on the described surface-mounted integrated circuit.
Advantage of the present utility model:
The utility model is the hinge of electric motor coach multichannel CAN messages between buses exchange, and mutual data communication device is crossed the CAN network router and transmitted between different sub-network, can significantly alleviate the load capacity of CAN bus.The utility model utilizes existing GPRS network resource; the real-time upload server of the parameter of required monitoring on the electric motor coach is preserved; make things convenient for user's query analysis, significantly reduced system's operation expense simultaneously, for scale, mass production electric motor coach provide technical guarantee.
