Description
Technical field
The present invention relates to a kind of method that is applied to the intelligent irrigation control of public lawn and soil moisturizing, specifically is the intelligent retaining rotational irrigation system at expressway greening band irrigation applications, belongs to the plumbing technical field.
Background technology
Under the situation that current water resource extremely lacks, using water wisely, raising water utilization rate have risen to important national development strategy, and popularization resource utilization height, reliability height, economical and practical watering equipment have become the task of top priority.
Especially passed through the great-leap-forward development of highway, the highway mileage of China leaps to the second in the world, how the greenbelt on the highway is irrigated just to have become a problem demanding prompt solution.What generally adopt at present is to irrigate with the sprinkling truck, people such as Wu Wenyong, Liu Honglu (2005) has analyzed the deficiency that the sprinkling truck draws water to irrigate, the running cost of pointing out this irrigation method be 3.57 ten thousand yuan/(a.km), be that more than 10 times of cost are irrigated in the other types greenery patches; Water application efficiency less than 50%; Annual roughly have time of 1/36 normally to pass through because the road occupying irrigation operation influence road.
Since 2000, some propose to carry out drip irrigation at central greenbelt, substitute the mode that the waterwheel that falls behind draws water to irrigate with this.The trial of this respect is mainly reflected in two aspects: the one, analyze the element of central greenbelt drip irrigation system, and preliminary design (Li Yu, 2000 are proposed; Yao Qingyun etc., 2005; Zhang Yanshuan, Zhou Liping, 2007; Wei Futing, 2007); The 2nd, on the basis of design, further carry out the test of on-the-spot drip irrigation, as (2008) such as Lan Bing on the Cheng Nan highway of Sichuan with sprinkling truck La Shui, be extracted in the cistern of eminence, carry out the drip irrigation test then; Liu Jianjun, Zheng Yong etc. (2008) carry out on-the-spot drip irrigation test, to understand the situation of change along aspect parameters such as journey hydraulic pressure, uniformity of irrigation water appilcation on hydrosphere expressway, Chongqing.In these researchs, source of irrigation water mainly utilizes highway reservoir along the line, river and motor-pumped well; The energy mainly relies on local electrical network.As a whole, because construction and the operating cost of drip irrigation system reality are higher, the situation of water dropper congestion affects drip irrigation system operate as normal takes place easily in addition, expressway central authorities greenbelt drip irrigation is still stagnated so far in the experimental study stage, is difficult to further deeply.
From the above, at present, the research work of highway rainwater catchment system aspect just just begins; Aspect central greenbelt irrigation, still do not find to substitute the effective ways that traditional sprinkling truck draws water to irrigate.
Summary of the invention
Irrigate situation of difficult at existing expressway greening band, the object of the present invention is to provide a kind of reliability height, applicability is strong, data validity is high, and the high intelligent rotation flow control method of water utilization rate.
The present invention is achieved in that
A kind of intelligent rotation flow control method comprises the steps:
Step 1, controller power on, and whether detect each several part voltage normal, if normally then forward step 2 to, if undesired, then shutdown system, maintenance detect;
Step 2, humidity sensor data acquisition, the transfer of data of collection are to controller, and controller judges that whether humidity is less than 50% of the relative moisture threshold values of setting, if then carry out step 3; If not, then continue this step;
Step 3, open total magnetic valve, judge then whether total water-supply-pipe is 1, if in 1 total water-supply-pipe of expression water is arranged, then opening a way solenoid valve in the downstream of water (flow) direction irrigates, if do not have water in 0 total water-supply-pipe of expression, then keep total magnetic valve to open 25 minutes, make in total water-supply-pipe to be full of water, and then a way solenoid valve of opening the downstream of water (flow) direction is irrigated;
Step 4, when opening a way solenoid valve and irrigate, controller receives the data that humidity sensor collects in real time, and judge that whether current humidity is greater than 55% of the relative moisture threshold values of setting, judge simultaneously whether current branch pipe(tube) reaches the irrigation time of setting, when the humidity value that collects greater than the relative moisture threshold values of setting 55% the time, close current way solenoid valve, close total magnetic valve again, total water-supply-pipe internal state is 1, opens discharging valve and discharges water; When the humidity value that collects less than the relative moisture threshold values of setting 55% the time, judge then whether current branch pipe(tube) reaches the irrigation time of setting, if reach, then close current way solenoid valve, judge whether again to irrigate and finish, judge that namely whether current way solenoid valve closing be a way solenoid valve of the upstream of total water-supply-pipe water (flow) direction, if, then irrigate and finish, close total magnetic valve, total water-supply-pipe internal state is 1, opens discharging valve and discharges water; If not, then do not irrigate and finish, open current the way solenoid valve that way solenoid valve water (flow) direction upstream is adjacent, proceed to irrigate;
Step 5, total water-supply-pipe internal state are 1, when the unlatching discharging valve discharges water, judge whether the discharging valve discharge time surpasses setting-up time, if do not have, then controller returns the collection of step 2 continuation humidity; If the discharging valve discharge time surpasses setting-up time, a way solenoid valve of then opening the downstream of total water-supply-pipe water (flow) direction carries out draining, judge whether to reach the water discharge time of setting then, the words that do not reach, then continue draining, if reach, then main road state puts 0, close this way solenoid valve, return step 2 and continue the humidity collection.
