为防止玻璃在储运过程中发霉，在玻璃之间需要撒一层防霉隔离粉。自动静电玻璃撒粉机实现了在线撒粉，可根据玻璃传输速度自动调整撒粉量，利用静电技术使撒粉均匀，附着力强。设计了以s7-200 PLC为基础的控制系统，重点介绍了控制系统的硬件配置、输入输出点分配和软件设计。测试表明：撒粉量为0.4～1.8 g/m2时,85%的粉附着于玻璃，满足玻璃的储运要求。

In order to prevent the glass from mildewing in storage and transportation, anti-mildew powder should be added between the glasses. The automatic electrostatic glass duster realized online powder spraying; the spraying rate varied depending on the transmission speed of glass. The homogeneity of powder and the adsorption force was improved by electrostatic technology. The control system based on s7-200 PLC was designed; the hardware configuration of the control system, distribution of input-output points and software design were discussed. The test results showed that the dusting amounts are between 0.4~1.6 grams per square meter; about 85% of powder can adsorb on glass; system function and accuracy can meet the needs of safe storage and transportation completely.
