Problems solved by technology
The minimum system structure of rod control in the early stage is relatively simple, the operation interface and operation logic are quite different from the on-site working conditions.
[0004] The current rod control system board test is mostly temporary tooling or simulation tooling. The test process is complicated and requires the cooperation of 1 to 2 people to complete, and requires a variety of equipment such as switching power supply, voltage regulating power supply, multimeter, oscilloscope, graphic recorder, etc. , the operation is complicated and the efficiency is low
