The wireless long-distance control is a hot issue in the realm of automatic control. Along with development of the mobile communication, short message serve (SMS) is popular with most customers because of its characteristics of agility, convenience and low price. Making use of SMS to carry out the long-distance control technology has practical value.
On the basis of studying the technology of long-distance communication and automatic control, this text is about that how to design a holistic solution which uses SMS and mobile phone module to implement long-distance control. Also we have designed the hardware circuit of the long-distance control unit and the interface circuit of SMS module. As a result, the hardware circuit of the wireless long-distance control system is achieved.
