一种具备总控功能的群控开关设计

Design of a Group Control Switch with the Master-Control Function

利用SNP2522单片机设计四路具备总控功能的群控开关,它包括触摸开关和多个与被控电器连接的开关电路组成。设计中采用光通管驱动电路获取控制输入信号,通过单片机软件设计实现单路、多路和总控功能,单片机控制输出通过双向可控硅构成的无极控制电路完成相关强电电路的控制。所设计的产品通过广东省质量监督局检验合格。

Uses the SNP2522 microchip, designs a four-channel group control switch with the master-control function, it composes a touch switch and several switch circuits connecting with the controlled equipments. The input signal is captured with the optical fiber driving circuit, implements the single-channel, multiple-channel and master control functions in the microchip software, and implements the control of the heavy current circuit through the endless control circuit which is composed by bi-direction thyristor. The proposed product passes the test of Guangdong Bureau of Quality and Technical Supervision.
