Design of Multiplex Power on_off Control Device Based on PT2262/2272

提出并设计了一种基于PT2262/2272的带状态返回的分布多路电源通断控制装置。该装置包括主控单元和受控单元两部分,两部分之间采用UHF无线通信交换信息,主控单元基于ATmegal6芯片完成对多路受控单元的控制和接收受控单元的返回信息,受控单元完成了控制指令的接收、执行,并提出了受控单元不用单片机返回状态信息的策略。实际运行表明,该装置不仅节约了布线成本,而且减少了故障点和故障率,可靠性得到提高,为开放实验室提供了基础数据。

Based on PT2262/2272,multiplex distributed power on_off control device with status return is presented and designed.The device is composed of two parts——active control part and passive control part,information exchange between which is based on UHF wireless communication.The active control part is centred upon Atmega16 to control multiplex passive control parts and receive their return information.The passive control part receives control command and execute,and a new status return method without a processor is given.The device is practically used,and a lot of wire is not only saved,but also fault places and fault ratio are decreased and reliability is improved.It provides experiment equipments work status data for the open laboratory.
