Abstract: Aiming that a number of objects in the same region were needed to control, the method that a message module controlled an object had large cost, complicated operation and other problems. In order to solve the problem, remote secondary control system based on GSM messages and RF modules was proposed. The system contained a base station and multiple nodes locating in the RF communication range of base station. Using the GSM messages, the users mobile phone achieved the first level control, the base stations remote control. Using the wireless RF, base station achieved the second level control, the multiple nodes regional control in the small region. Reseach results indicate that this system reduces system costs, simplifies system circuit. It can be applied to many control areas such as smart home, access control systems, and agricultural irrigation and has certain application value.
