Problems solved by technology

[0003] In recent years, some progress has been made in the research of correlation irrigation control technology and method. Among them, Chinese patent document CN102037888A discloses a "distributed network automatic irrigation control system and its irrigation application method". A two-level distributed control system composed of irrigation units. The patent patent "Remote Automatic Irrigation System and Application Method Based on Public Communication Network" with the publication number CN1951170A has constructed a two-level irrigation automation system composed of a central control level and a field control level. However, the lower-level control system in these technical methods only uses a single processor (CPU) to complete tasks such as...

Embodiment 1

[0046] This embodiment provides a three-level control system for large-area multi-field automatic water-saving irrigation, which is introduced with two fields. The three-level control system includes a remote monitoring platform, at least one monitoring station and multiple monitoring terminals; among them, the data communication between the remote monitoring platform and the monitoring station is carried out in the form of GPRS, and the data communication is carried out between the monitoring station and the monitoring terminal through the ZigBee network .

[0047] The remote monitoring platform 1 selects a server with monitoring software installed and a public network IP. Among them, the monitoring software is a management application program for automatic water-saving irrigation control compiled using technologies such as databases, tables, electronic maps, network clients, and network communications. The location and boundary of the field and the icons of the location of ...

Embodiment 2

[0059] This embodiment provides a method for using a three-level control system for automatic water-saving irrigation of multiple fields in a large area. To realize the automatic water-saving irrigation control of different types of crops in different growth stages in multiple fields in a large area, the steps are as follows:

[0060] (1) The monitoring software on the remote monitoring platform 1, according to the experience of experts, prepares the irrigation water consumption plan control table for crops in different growth stages in different fields for the soil properties, components and crop types on different fields. The essence of this control table is The corresponding table of the upper limit and lower limit threshold parameters that need to be controlled in different time periods for the humidity and temperature of soil in different fields.

[0061] When the irrigation control system is in operation, the monitoring program of the remote monitoring platform 1 automat...

Embodiment 3

[0065] This embodiment provides an implementation method for illustrating a three-level control system for automatic water-saving irrigation of large-area fields.

[0066] A relatively common situation is that there is only one source of irrigation water for a large-scale field or multiple fields (such as a motorized well or a pond), and there are particularly many branches that require irrigation water, so many monitoring terminals 3 are used. In view of this situation, using one monitoring station 2 to control the total number of monitoring terminals 3 for irrigation operations at the same time and implement sequential rotation irrigation can solve the irrigation control problem of large-scale or multi-field plots with relatively low-cost water supply equipment.

[0067] Calculate the water consumption per unit time of the irrigation operation based on the irrigation area and the minimum round irrigation interval time, so as to determine the power of the water pump motor and ...

Abstract

The invention relates to a large-area multi-field-piece automatic water-saving irrigation three-level control system and a use method thereof. The three-level control system comprises a remote monitoring platform, at least one monitoring station and a plurality of monitoring terminals; the remote monitoring platform and the monitoring stations conduct data communication in a GPRS mode, and the monitoring stations and the monitoring terminals conduct data communication through a ZigBee network. Temperature and humidity data of field pieces is collected through temperature and humidity sensors of the monitoring terminals and compared with temperature and humidity threshold values pre-stored in ZigBee modules of the monitoring terminals; when conditions are met, an irrigation request is sent to the monitoring stations, and meanwhile management personnel can modify the temperature and humidity threshold values through the remote monitoring platform and issue the modified temperature and humidity threshold values to the monitoring stations. The three-level control system can achieve control over automatic water-saving irrigation of multiple field pieces in a large area, manpower cost is saved, water resources are saved, manual intervention can be carried out, and the purpose of reasonable water-saving irrigation is achieved.

Description

technical field [0001] The invention relates to a three-level control system for automatic water-saving irrigation in large areas and multiple fields and a method for using the same, belonging to the technical field of automatic irrigation. Background technique [0002] The increasing scarcity of freshwater resources and the gradual increase in labor costs have made automatic water-saving irrigation technology an important direction for the development of modern agriculture, forestry, animal husbandry, and sideline water irrigation. At present, how to realize the automatic water-saving irrigation control of large-area and multi-field plots has become a prominent problem to be solved for the large-scale land transfer and cooperative management in my country's agriculture, especially the vast northeast, northwest and other agricultural, forestry, animal husbandry, and sideline bases. [0003] In recent years, some progress has been made in the research of related irrigation co...
