I. Description of the status quo

Lack of rain and water is a major bottleneck for agricultural development. However, most of the farmland nowadays uses wired methods to transmit terminal data and control instructions. In this way, backward management methods are not only expensive in terms of system cost, but also cause troubles in cabling and maintenance. The cost is also high, and the networking mode is less flexible.

Second, demand analysis

At present, most domestic micro-irrigation systems use wired methods to collect and transmit public opinion information. This method not only makes it difficult to construct on-site wiring, but also is inconvenient for management and maintenance, and the networking mode is not flexible. In addition, if the area of the farmland is large, the cost of wiring costs is also more expensive than the wireless method.

Another proposed use of GSM / GPRS, CDMA, and other wireless communication module to transfer information, but GSM / GPRS wireless communication module prices are relatively high, the use of charges, and need to rely on public communications network, taking into account the farms are in remote areas, multiple It is not feasible to receive signals, and some point-to-point short-range wireless communication modules are proposed. The network performance is poor, and large-scale networking is not possible.

Sixin Communications uses ZigBee, a rapidly developing new communication technology, together with the original IP modem, to become a ZigBee wireless communication product with GPRS. With the support of the public communication network as the convergence point, the low-power consumption and wide distribution area are required. In the crop planting area, the networking is convenient, and the network construction cost is low. It is suitable for use in the micro-irrigation measurement and control system. It is used to complete the collection and transmission of public opinion information and to control the solenoid valve action, thereby completing the entire micro-irrigation control process.
