Embodiment 1
[0055] Such as figure 1 As shown, an irrigation control method, which includes an over-limit control mode,
[0056] In the overrun control mode:
[0057] The pre-set starting conditions include a maximum delay time. When the irrigation equipment is started, the timer counts the running time of the irrigation equipment. If the irrigation equipment is started again within the maximum delay time, the timer resets and starts counting down again. ;If the irrigation equipment is not started again within the maximum delay time, the irrigation equipment will be started automatically;
[0058] The preset start-up conditions include the daily maximum irrigation volume / time, and make statistics on the daily irrigation water volume / time of the irrigation equipment. Do not start.
[0059] In the over-limit control mode, the present invention introduces the maximum delay time for sensor failure or measurement error (measured value is too high) for a long time without starting irrigation,...
Embodiment 2
[0122] Such as figure 2 As shown, the embodiment of the present invention also provides an irrigation device:
[0123] Contains the following sections:
[0124] The sensor and status acquisition module is used for real-time acquisition of connected sensor signals and irrigation equipment operation status signals;
[0125] The controllable power supply output module cooperates with the sensor and state acquisition module to realize time-sharing data conversion for sensors connected to different channels;
[0126] Latch type solenoid valve control module, to realize the opening / closing operation function of specific valves;
[0127] An external clock to provide a clock reference for the entire device;
[0128] The data storage module is used to store the parameters set by the system and the sensor historical data saved regularly;
[0129] Buttons and LCD human-machine interface module are used to set different control logics, system parameters and equipment operating parame...

Abstract
The invention provides an irrigation control method and an irrigation device and relates to the technical field of agricultural irrigation. The method includes an over-limit control mode. According to the over-limit mode, preset starting conditions comprise maximum delay time, when the irrigation device is started, a timer perform timekeeping on running time of the irrigation device, and if the irrigation device is started again within the maximum delay time, the timer resets and starts to count down again; if the irrigation device is not started again within the maximum delay time, the irrigation device is started automatically; the preset starting conditions comprise daily maximum irrigation amount / time, statistics is performed on daily irrigation water amount / time of the irrigation device, and when the statistic irrigation water amount / time reaches the daily maximum irrigation amount / time, the irrigation device will be forbidden from being started again in the same day. Excessive irrigation or insufficient irrigation caused by sensor failures or unreasonable parameter setting is effectively reduced, and damage, possibly caused by the excessive irrigation or the insufficient irrigation, to crops is effectively reduced.
Description
technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to an irrigation control method and an irrigation device. Background technique [0002] The effective irrigated area of farmland in my country ranks first in the world. With the increasingly severe situation of water shortage and the low utilization rate of agricultural irrigation water in my country, water-saving technology and automatic irrigation control technology have been widely used and become the national agricultural development strategy. . [0003] The Chinese patent announcement number is CN102037888A, which discloses a distributed network automatic irrigation control system and its irrigation control method. By comparing the measured value of soil moisture with the threshold value, the opening and closing of the irrigation pipeline is controlled to realize automatic irrigation. It controls and realizes the ad hoc network data communication network throu...
