Description

A kind of automatic irrigation system

Technical field

The utility model relates to a kind of agricultural automation equipment, specifically a kind of automatic irrigation system.

Background technology

China's Water Consumption in Agriculture accounts for about 80% of total water amount, because agricultural irrigation efficient is generally low, the availability of water only is 45%, and the high country of water utilization rate has reached 70% ~ 80%.Traditional artificial Timing measurement not only expends a large amount of manpowers, and does not accomplish Real Time Monitoring, its Irrigation far can not adapt to the needs of agricultural sustainable development, if adopt wired TT﹠C system, then needs higher wiring cost, be not easy to expansion, and make troubles to farming operation.

The utility model content

The purpose of this utility model just provides a kind of automatic irrigation system, to solve the low problem of water utilization rate.

The utility model is achieved in that a kind of automatic irrigation system, comprising: single-chip microcomputer, soil humidity sensor, signal conversion module, digital temperature sensor, digital humidity sensor, key-press module, clock chip, display module, power module, driver module, magnetic valve and buzzer;

Described soil humidity sensor is connected with described signal conversion module, described signal conversion module is connected with described single-chip microcomputer, described digital temperature sensor, described digital humidity sensor, described clock chip, described display module, described power module and described driver module are connected with described single-chip microcomputer respectively, and described driver module is connected with described buzzer with described magnetic valve respectively.

The key information that the utility model collects by single-chip microcomputer is realized irrigation duration, the isoparametric setting of minimum Soil moisture under timing, each pattern.

The utility model can in time be controlled irrigation time and the water yield according to the on-line monitoring to soil information, thereby has avoided wired wiring inconvenience, relatively poor shortcoming of flexibility.The utility model can improve water utilization rate, alleviates the contradiction that China is becoming tight water resource day, thereby makes up high energy efficiency, low consumption, few input, multi-functional agricultural water-saving irrigation platform.

Fig. 1 is the utility model structural representation.

Embodiment

As shown in Figure 1, the utility model comprises: single-chip microcomputer 1, soil humidity sensor 2, signal conversion module 3, digital temperature sensor 4, digital humidity sensor 5, key-press module 6, clock chip 7, display module 8, power module 9, driver module 10, magnetic valve 11 and buzzer 12.

Described soil humidity sensor 2 is connected with described signal conversion module 3, described signal conversion module 3 is connected with described single-chip microcomputer 1, described digital temperature sensor 4, described digital humidity sensor 5, described clock chip 7, described display module 8, described power module 9 and described driver module 10 are connected with described single-chip microcomputer 1 respectively, and described driver module 10 is connected with described buzzer 12 with described magnetic valve 11 respectively.

The utility model comprises two kinds of working methods:

The first working method is that soil moisture content detects control model: the resistance value that is inserted in the resistance-type soil humidity sensor 2 in the soil can change because of the variation of soil moisture content, and soil moisture content is larger, and the resistance of sensor is less.The resistance signal of soil humidity sensor 2 converts voltage signal to by signal conversion module 3, signal conversion module 3 is sent to voltage signal in the A/D translation function I/O mouth of single-chip microcomputer 1, carry out analytical calculation by 1 pair of voltage signal that collects of single-chip microcomputer, draw corresponding soil moisture value, and compare judgement according to the minimum soil moisture value of user-selected pattern and setting, determine whether start irrigation, and show corresponding soil moisture value.Simultaneously, when single-chip microcomputer 1 can decide according to the irrigation duration that the user sets shut electromagnetic valve 11 and show and stop countdown.

The second working method is the timing irrigation pattern: the user can arrange as required every several days when irrigate, when timing mode is opened, system can compare according to user the interval fate that arranges and the fate that has experienced, at this moment, the time of real-time time and setting compares, when real-time time meets the time of user's setting, system starts irrigation automatically, simultaneously when single-chip microcomputer 1 can decide according to the irrigation duration that the user sets shut electromagnetic valve 11, can show that simultaneously corresponding irrigation starts countdown and stops countdown.
