Problems solved by technology
[0004] (1) The cross-mining board does not have the function of measuring the charging voltage and current of the supercapacitor, and cannot detect the working status of the supercapacitor in a timely manner, which brings hidden dangers to the safety and stability of the operation;
[0005] (2) There is no debugging module for the inter-acquisition board, and the overall debugging can only be carried out after connecting the inter-acquisition board of the intelligent platform terminal with the main control board, which increases the workload of debugging and disassembly, reduces the debugging efficiency, and is not convenient for early detection The problem of the exchange board;
[0006] (3) There is no debugging software for debugging the cross-mining board, so it is not easy to find and find the defects and problems of the cross-mining board
