基于数字电桥的CI-SR800黑体全自动控制方法

CI-SR800 Blackbody Full-automatic Control Method Based on Digital Bridge

提出了一种基于数字电桥的CI-SR800黑体全自动控制方法,在不影响黑体原有使用方法前提下,使黑体能够接入全自动测试流水线。根据CI-SR800黑体使用的4线电阻触摸屏和内部蜂鸣器,设计了数字电桥电路和蜂鸣器检测电路。在考虑施工的可操作性、美观性等要求的同时,有针对性的进行了一系列设计,通过黑体控制器预留的IO接口,采用并联的方式引出触摸屏的4芯导线和蜂鸣器的2芯导线。根据黑体人机接口的实际工作原理,设计出与该黑体配套的控制电路。实际应用表明,该设计方案便于安装、免维护、运行稳定。

A full automatic control method of CI-SR800blackbody based on digital bridge is proposed to allow the blackbody to access the full-automatic test line without affecting the original using method.According to the4wire resistance touch screen and an internal buzzer used in CI-SR800blackbody,the digital bridge circuit and the buzzer detection circuit are designed.A series of design are carried out,in consideration of the requirement of the construction operability and appearance at the same time.4wires of the touch screen and2wires of the buzzer through the IO interface reserved by the blackbody controller are led in parallel method.A control circuit for the blackbody is designed based on practical working principle of the blackbody man-machine interface.The practical applications show that the design is easy to install,maintenance free and stable in operation.
