And test parameter, all testing can be automatically performed by testboard, automatically generated testing journal sheet and shown result, while there is process
Abnormal and overproof prompting, simple operation, intelligence degree is higher, greatly improves testing efficiency and quality.Further, since test
Process can be designed arbitrarily, can easily be set to various test modes, the need for adapting to subsystem test, and be test result
Automatic interpretation lays the first stone.
2nd, it is compact portable, Highgrade integration.Present invention collection control computer, CAN module, channel switching equipment, adopt
Integrate equipment, compact portable, easy to operate, integration degree is high.
3rd, modularized design, autgmentability is strong.The present invention connects design using CAN, and all units are that modularization is set
Meter, can conveniently be extended.By the communications protocol from difference in functionality, easily expanded mode it can draw up more confession distribution and set
It is standby；Modular design also makes the maintenance maintenance of equipment become abnormal convenient in addition.
