Automatic control system for groundwater limited exploration based on low cost network

In the remote automatic control irrigation system, the cost of data communication, generally accounts for 50% of the total input of the project. According to the practice of the engineering, starting from the part of data transmission, low cost network, wireless half duplex high-rate data communication based on narrowing the transmission bandwidth of radio channel, database ADO technique, and the anti-interference technology such as shunting the water pump switching time with the time of the data collection and communication and were applied to the automatic control system for groundwater limited exploration. The engineering construction price was lowered, and the technique economy of the whole system was remarkably improved.
