The invention relates to a GSM / CDMA-based network remote control intelligent switch system. A mobile phone sends a signal to a signal receiver through a GSM / CDMA network, a human-machine interface sets a parameter signal to be sent to the signal receiver, the signal receiver receives the signal and then sends the signal to an A / D converter and a D / A converter through a wire coiler for transformation processing, then the transformed signal is sent to a programmable logic controller through a signal wire, the programmable logic controller outputs a control signal to a power amplifier to drive a controlled switch to act, a solar cell supplies power to the signal receiver, and an alternating-current power supply is used as a standby power supply for supplying power to the power amplifier. The GSM / CDMA-based network remote control intelligent switch system has the characteristics of no limit to distance, higher intelligent degree, high safety and stability and low cost, is convenient for operation, can realize operation on a plurality of switches with different functions by using the mobile phone commonly used by people, and has higher social and economic values.
Description
technical field [0001] The invention relates to a control technology, in particular to a GSM / CDMA network-based remote control intelligent switch system. Background technique [0002] The degree of remoteness and intelligence of ordinary switches is low, and operators must operate the controlled switches on site or at close range remotely, which causes various inconveniences to industrial production and people's daily life in today's society, and cannot meet people's needs for production. , The needs of life. [0003] The existing patents disclosed at present can complete basic functions such as remote control and automatic switch, but the integration degree of each function is not high, and the market competitiveness is not strong. Published patents include: [0004] 1. Tang Xuezheng, No. 12, Dongting Road Fourth Avenue, Tianjin Economic and Technological Development Zone, Tianjin; Wang Bingqiang; Li Chengji invented the water level remote monitoring and early warning sys...
