The beneficial effects of the utility model：Working power is divided into programmable power supply and industrial personal computer power, by channel selecting control
Device processed realizes that device working power is shown in switching in high pressure and low pressure, and high voltage power supply is powered to industrial computer, and low-tension supply is to CAN cards
Group, Bus analyzer（CANscope）, bus test interferometer（CANstress）, bus test module（CANoe）Power supply.Dress
Put by terminal adapter before the connection of BOB adapters, real stand real vehicle load is connected by EDAC backend connectors, work is carried
Control machine system, the upper computer software being provided with industrial computer needed for CAN cards, the software can realize real-time control to CAN cards, realize
Dummy load carries out digital switching with real channel.
Tested ECU1 ~ 3（If multiple ECU are then direct-connected downwards using order）By adapter and the front controller of device
It is connected, load end is direct-connected with the backend connector of device by stand adapter, the connect load of test-bed is the true of ECU controls
Actual loading, such as car light, lock, glass-frame riser, air conditioning system etc., all direct-connected lines are using the process of anti-interference sleeve pipe.Entirely
When device works, real-time control can be realized by test management platform software system, that is, realize truly switching with dummy load.Such as
When being experimental stand using true or dummy load, by gather the output end voltage electric current of single or multiple ECU Jing devices from
It is dynamic to judge that whether normally the ECU function operations, realize the automatic test of ECU allomeric functions with this.
