Then, it performs AC / DC conversion on the filtered 220V AC power supply using a 220V AC to 28V DC power supply module, obtaining a stable 28V power supply with an output load capacity of not less than 150W, which can meet the communication needs of most electric drive controllers. Finally, considering safety requirements, a reverse voltage protection diode is added at the 28V output interface to protect the electric drive controller from damage due to reverse voltage. The multi-bus transmission module 3 receives power from the power filtering and conversion module 2 and transmits data with the status monitoring and maintenance module 4. This module includes: CAN communication hardware device sub-module 31, CAN communication hardware device selection and setting module 32, 422 communication hardware device sub-module 33, 422 communication hardware device selection and setting module 34, 429 communication hardware device sub-module 35, and 429 communication hardware device selection and setting module 36.

It can realize rapid testing, visual monitoring, fault diagnosis, data storage, and upgrade maintenance of electric drive controllers, effectively reducing the time and cost of production, testing, inspection and repair.

[0035] In the specific implementation process, in order to achieve automatic selection of bus communication mode, a bus transmission autonomous selection module can be added to the device. When the controller is powered on, the bus transmission autonomous selection module automatically obtains the controller's communication mode, and activates the corresponding communication hardware device selection module in the multi-bus transmission module according to the obtained controller's communication mode. Then, the communication hardware device is activated, and data is automatically transmitted with the multi-bus transmission module, and the controller's working status is displayed in real time.

[0036] By adopting the self-selected bus communication method designed above, in application scenarios such as field equipment maintenance, fault diagnosis, and software upgrades, only power supply to the controller is needed to obtain all the controller's working status and data, without relying on complicated testing equipment and complex testing procedures, which can significantly improve maintenance efficiency.
