Automatic Test Control System Design for Mobile Phone Charger

手机充电器自动测试系统,以GPIB通信卡、PCL720控制卡、PLC、光电传感器、磁感应器等为核心,整个过程由链条带动运输板完成充电器的传输,并自动进行安全规格测试和功能测试。安全规格测试包括输入电流、漏电流、耐压绝缘、温度抗燃、机壳接地、变压输出特性等。功能测试含输出电压、电源和负载调整率。

Mobile phone charger automatic test system takes the GPIB communications cards, the PCL720 control card, PLC, the electro-optical sensors, the magnetic sensors and so on as a core. The entire process completes through the charger＇s transmission by using the transportation board, which is driven by the chain link, and the automatic progress of the security specification test and the functional test. The security specification test includes the input current, leaks the electric current, the pressure resistance insulation, the temperature anti-burns, the cabinet earth, live pressure input level and so on. The function test contains the output voltage, the power source and the load regulation rate.
