103 coil losing electricities are closed, and keep the normally closed of manual normally close valve 302, are compared a wide range of water circulation, specific circulating path
For first circulation pipeline 902, direct-furnish pipeline 911, the common pall 912 of low tank supply channel 904 and first；Or magnetic valve 103
Open, magnetic valve 102, magnetic valve 104 close, carry out the water circulation of small range, circulating path is second circulation pipeline 903, the
Two common palls 914 and the first common pall 912；Or magnetic valve 102, magnetic valve 103 are closed, magnetic valve 104, magnetic valve
107 open progress drip irrigation.
It is big more than in order to show photovoltaic irrigation effect in the case where irrigating completion and illumination condition permission
Two circulating paths of scope water circulation and small range water circulation, carry out two kinds of water circulation displayings.
2nd, automatic water filling and draw water.After system starts, low level water storage is detected by liquid level sensor 503 and 504 first
Liquid level in tank 701, if in low liquid level, liquid level sensor 504 gives the feedback signal of single-chip microcomputer one, and single-chip microcomputer handles the feedback
Signal, control magnetic valve 101 opens toward in low level water tank 701 water filling (while keeping the normally opened of manual normally open valve 201, manually
Normally close valve 302 it is normally closed), when reaching high level, liquid level sensor 503 provides feedback signal, and single-chip microcomputer is required according to control
Sprayed, water circulation or toward water filling in high-position water-storage tank 601.Toward during 601 water filling of high-position water-storage tank, repeat above-mentioned past first
The process of the water filling of low level water tank 701, it is ensured that low level water tank 701 is on the premise of high level toward in high-position water-storage tank 601
Water filling.In the case where illumination condition allows (supply of electric power for ensureing photovoltaic module), single-chip microcomputer sends signal enabling immersible pump
801, magnetic valve 101,103,104,106 is closed, the water opened in magnetic valve 105, low level water tank 701 passes through the first share pipe
Road 912, the second common pall 914 and tall can inlet pipeline 905, into high-position water-storage tank 601.High-position water-storage tank 601 added water
Cheng Zhong, single-chip microcomputer detects the high level signal of liquid level sensor 501 all the time, when reaching high level, closes immersible pump 801 or carries out
Water circulation.
3rd, automatic irrigation.During daytime, after the photovoltaic time control automatic irrigation system of the embodiment of the present invention starts, in illumination condition
In the case of abundance, single-chip microcomputer is received after the high level signal of the liquid level sensor 503 of low level water tank 701, control electricity
Magnet valve 101,102,103,105,106,107 is closed, while keeping the normally opened of manual normally open valve 202,205, starts immersible pump 801
Sprayed, can be by the way of the sprinkling irrigation timesharing of 3 tunnels be opened when being sprayed, for example magnetic valve 108 is first opened half an hour, together
When magnetic valve 109,110 close；Similarly, when magnetic valve 109 is opened, magnetic valve 108,110 is closed；When electromagnetism 110 is opened, electromagnetism
Valve 108,109 is closed, and can be sprayed per road work half an hour, controlling switch is given after the completion of being repeated 4 times the process, sprinkling irrigation process daytime
Immersible pump 801 is powered off, and stops sprinkling irrigation (closing magnetic valve 108,109,110).
Drip irrigation is carried out, can be first from low level water tank 701 toward the inner note of high-position water-storage tank 601 when high-position water-storage tank 601 does not have water
Water, when detecting the high level signal of liquid level sensor 501, Single-chip Controlling immersible pump 801 is stalled, and opens magnetic valve
106th, 107, magnetic valve 102,104,108,109,110 is closed, while keeping manual normally close valve 302 to be in normally off, manually
Normally open valve 202,204 is in normally open, carries out drip irrigation；If the reclaimed water of high-position water-storage tank 601 reaches low liquid level during drip irrigation,
The process that adds water to high-position water-storage tank 601 is then again started up in the case where illumination condition allows.
During night, drip irrigation is only carried out, control process is similar with drip irrigation control process on daytime, simply until high-position water-storage tank
601 water when being finished can not moisturizing again, during whole irrigate, single-chip microcomputer constantly receives the soil from soil humidity sensor
Moisture signal, once detect soil moisture it is excessive when, the corresponding magnetic valve of Single-chip Controlling and immersible pump 801 stop irrigating simultaneously
Alarm.
4th, meet an urgent need and irrigate.When whole system breaks down, manual normally open valve 201 can be turned off, manual normally close valve is opened
302, while opening manual normally close valve 301, directly irrigated with running water.
The photovoltaic time control automatic irrigation system of the present invention, can effectively utilize solar energy, and realize automatic enclosed circulation central, and
And external power source is used as few as possible.Whole photovoltaic time control automatic irrigation system realizes the whole automation for irrigating process,
Soil humidity sensor and dropper road, the mutual cooperation of pipeline of sprinkling irrigation, reduce while Optimum Irrigation effect is ensured and use water
Amount, the demonstrating effect of system is added on the premise of practicality is greatly reinforced, photovoltaic can be intuitively experienced to irrigation
Influence.And the control system adds the stability of whole irrigation system operation, reduces the maintenance in later stage.
The pipeline connecting mode that sprinkling irrigation and drip irrigation are combined, unattended, self energizing, closing are realized by using solar energy
Circulation, automatic irrigation crops.
Urban landscaping can either be applied to, is suitable for gardens, the crop irrigation in outlying non-transformer area again.
