Water-fertilizer integrated intelligent irrigation systems based on 485 buses
Technical field
This utility model relates to water-fertilizer integral irrigation technique, specifically water-fertilizer integrals based on 485 buses Intelligent irrigation system.
Background technology
The Integration of Water into Fertilizer is new agricultural technology irrigation technique and fertilizer practice combined together.Water-fertilizer integral is By pipeline pressure irrigation system, solution soluble solids fertilizer or liquid fertilizer dissolved is together with irrigation water, all Even, be transported to crop root soil exactly.Use intelligent irrigation fertilizer practice, can carry out according to the demand of crop growth The time of infertility, Demand Design, moisture and nutrient quantitatively, regularly, was supplied directly to crop in proportion.
This technology is suitable for there are the fixing water sources such as well, reservoir, cistern, and water quality is good, meet irrigation requirement, and built If or the region popularization and application of construction irrigating facility of having ready conditions.It is primarily adapted for use in installment agriculture growth, orchard cultivation and Cotton Gossypii, cigarette The land for growing field crops industrial crops cultivations such as grass, and other crops of better economic benefit.
Currently for the Integration of Water into Fertilizer, being all manual intervention, the real needs for crops carry out manual detection Judge, and carry out real-time adjustment irrigation, the concrete growing environment of the reaction crop that so data of monitoring can not be in good time, and In good time feedback can not be accomplished, also waste manpower.
Summary of the invention
This utility model is water-fertilizer integrated intelligent irrigation systems based on 485 buses, and it is based on 485 communications, real Show multi-node communication and long haul communication balance transmission, the advantage of differential received in water-fertilizer integral irrigation system, had Preferable anti-common mode disturbances ability.
This utility model realizes above-mentioned purpose by the following technical solutions:
Water-fertilizer integrated intelligent irrigation systems based on 485 buses, it includes host module, controls to connect node module, execute Fertile node module and acquisition node module.
Described host module, control module, fertilising node module and acquisition node module be consecutively connected to 485 communicate total Line, described host module is connected to Internet Server by DTU；The described outfan controlling node is connected to accordingly Water pump, the outfan of described fertilising node is connected to described fertilizing pump；Described acquisition node connects has temperature detection to fill Put, moisture content detection device and pipeline flow detection device.
Preferably, the described outfan controlling node connects parasite killing signal controlled switch.
Preferably, described fertilising node connects and has water body salinity, PH detection device and pipeline pressure, flow detection dress Put.
Preferably, the outfan of described acquisition node is connected to electromagnetic valve.
This utility model uses technique scheme to have the advantages that
1, engineering construction is simple: the engineering construction of this system is simple, and all of project equipment has only to on-the-spot with one 485 The communications cable connects, it is not necessary to other operation；
2, system stability performance is strong: due to use 485 buses as the communication network of system, so this system than other is System has higher capacity of resisting disturbance, and especially in the area that electromagnetic environment is complicated, the data loss rate of 485 communications, communicate matter Amount, communication success rate are all good, demonstrate excellent communication performance；
3, cost performance is high: this system uses electric supply system, than solar electric power supply system, has low cost, fault The advantages such as rate is little, greatly reduce the cost of engineering construction；
4, communication distance is long: the standard traffic distance of 485 buses is 1200 meters, up to several public affairs after plus 485 repeaters In remote, meet far away the needs of field irrigation, so, communication distance length is also the important feature of 485 bus water-fertilizer integrals；
5, intelligentized control program: this system passes through the soil moisture, moisture transducer, and detection soil moisture contains in real time Amount, meanwhile, system has manually, automatically, and the period, the multiple-working mode such as flow, each mode of operation combines soil data, Water-fertilizer integrated intelligent can be implemented efficient, irrigate accurately；
6, water-saving fertilizer-saving, time saving and energy saving: this control system and water-fertilizer integral combine, it is possible to according to the relevant ginseng of soil Number, precisely, efficient fertilizer irrigation.Simultaneously as system is entirely intelligent management, therefore save substantial amounts of human cost. The more preferable growing environment of crops, increasing both production and income can be given.
