For finding a way to guard against theft and operate irrigation and spray equipment automatically of remote orchard pump house, an intelligent monitoring system was developed and tested. The system can accomplish two functions, including telephone dialing alarm and remote control with micro controller unit as the core, with dual-tone multi-frequency remote data transmission technology. The system was tested in the given orchard and it proved that the successful rate of accomplishing the functions was 96.5%, the alarm average response time was 4.58 s, the remote controlling average response time was 23.27 s, and every time the cost of communication was the normal telephone fee. Experiments show that the system can accomplish its functions and satisfy the requirements of guarding against theft and remote controlling irrigation and spray equipment of orchard pump house. 
