Design of Test Automation System for a Decoding Output Drive Circuit
An automatic test system is designed for a certain type of dual redundant decoding output drive circuit.Based on the analysis of the test principle,the overall design of the automatic test system is determined.Using industrial computer,programmable equipment and control load board to complete the overall architecture design of the system,and then design the hardware circuit and software program,and introduce the main circuit chips.In the experiment,the automatic test system is used to test the product and compared with the manual test system.The results show that the automatic test system shows high efficiency and accuracy,and has the advantages of simple operation.
