The total line technique of the spot is already to two metalcores carry an electric cable control 10 control technique that Km distances expansion stage, but on our country of the big field agriculture irrigate to control the system application, according to the total line method return very weak. Current and big field the auto that irrigate control many adoptions of systems to directly import, and the technique is advanced, function stability, but the cost is expensive, very rare expand application to the big area; Therefore, design that draw lessons from forerunner thought, the development have the right of independence knowledge property of according to the spot is total to line irrigate to control the system and with it the kit's central controller control the unit with terminal, and lower to throw in the cost, and increase the equipments's dependable, easy operability, can promote to higher grade the sex with standardize to wait the main technique index sign, and match the agriculture modernization to development automate technique need. the automatic control system is a development to irrigate controller, and irrigate the controller should have the dependable, easy operability, and can promote to higher grade the sex with internationalize to wait the characteristics supervise and control the system, and have to use the line little, solid hour good, flat-out quick etc. Advantage, and adoption the touch hold operation, safety dependable easily operate. This system is now and already at 111 regiment 1 connected to start experiment, obtain the anticipant result. The technique function is strong, and the cost is significant to lower, and is an agriculture to modernize the alignment the information the essential to have's step. can break the large unit the automation to irrigate to control the technique the main counting on the situation that import at the same time, and the demonstrate expand to have the large unit independence knowledge property the power's management software. Keywords:CAN bus RTU automatic control irrigation choke supervision 参考文献 [5]夏继红,严忠民,周明耀,等.农田灌溉决策支持与控制系统的设计与应用[J].河海大学学报,2001,29(6):6-10 |
