Problems solved by technology

[0006] In the technology of automatic irrigation calculation, the transmission method of the control signal is a relatively key link. In the known technology, there are two methods of wired and wireless transmission, among which the wireless transmission method is the first choice, and in the wireless transmission, methods such as setting a radio station or a wireless local area network All due to the high cost of construction seriously affects the research and development and promotion of the above technologies

Embodiment 1

[0015] Example 1: An automatic irrigation system for controlling 4300 mu of cotton fields by means of pressurized drip irrigation.

[0016] In different stages of cotton growth, the lack or excess of water and its degree have obvious effects on the yield of cotton. At different growth stages of cotton, there is a suitable range of soil moisture, and if it is less than this range, it will cause cotton production to decrease. At present, drip irrigation of cotton fields is realized by manually operating a large number of valves. The irrigation cycle is usually 5-6 days. However, according to research, in the high temperature period, the possibility of cotton being irrigated at intervals of 7 days is very high. The soil moisture content on the day of irrigation It tends to be saturated. With water leakage, transpiration and crop absorption, the soil water content tends to the crop wilting point after it is lower than about 15%. In order to maintain the effective water holding cap...

Embodiment 2

[0026] Embodiment 2: Use the system in Embodiment 1 to perform automatic irrigation according to expert decision-making. Comprehensive analysis and fuzzy control calculation based on the expert database based on various parameters such as automatically collected and manually entered plot information, irrigation system information, crop varieties, growth stages, soil properties, soil components, weather forecast, weather conditions, accumulated temperature, etc. , and automatically generate irrigation and fertilization plans. After each irrigation plan is generated, the system automatically sends a text message to the management personnel to request approval. The management personnel can directly approve the irrigation plan through the text message, adjust the plan or reject the plan. The plan approved by the management personnel is automatically executed by the system.

[0027] Managers can also forcibly suspend ongoing irrigation plans.

Embodiment 3

[0028] Embodiment 3: Use the system in Embodiment 1 to perform automatic irrigation with soil moisture as the main parameter. The system includes soil moisture sensors to continuously measure the soil moisture at typical points, and automatically irrigates based on multi-point soil moisture symptoms. The irrigation volume is evenly distributed to each wheel irrigation area according to the proportion of the plot area. perform tasks.

Abstract

The invention relates to a remote irrigation automatic method based on public communication network. Wherein, it has central control stage and field control stage; the central control stage is formed by central detecting station formed by central detector, public module and software; the field control stage is formed by several field irrigation controllers and several electromagnetic valves. The invention has the advantages that it can use irrigation software to complete automatic control and combine the parameter measurement and automatic irrigation, with automatic control, remote or hand control. And it can realize integrated management via communication network. The invention also can detect the condition, grow state of plants.

Description

1. Technical field [0001] The invention relates to an automatic irrigation of agricultural water conservancy, which belongs to the field of automatic control of water conservancy irrigation, in particular to a remote irrigation automatic system and control method based on a public communication network. 2. Background technology [0002] At present, the field irrigation technologies commonly used in the world include non-surface irrigation such as surface irrigation, sprinkler irrigation and underground drip irrigation. Among the known irrigation technologies, it is generally determined whether irrigation is needed based on the soil moisture data measured in advance and combined with planting crops, and Which type of control is used for irrigation, after measuring the water consumption and electricity consumption of irrigation, and then controlling various irrigation facilities, such as well motors, pipeline solenoid valves, open channel gates, etc., and measuring their meteri...
