Abstract
The utility model provides a long -range constant voltage irrigation system of greenhouse vegetable comprises humidity transducer, level sensor, cistern, moisturizing unit, water supply unit, PLC controller, converter, GPRS remote communications equipment and remote terminal. Its theory of operation: remote terminal monitors the PLC controller through GPRS remote communications equipment, and humidity transducer is gathered to the PLC controller, and the analog signal of level gauge controls opening and close of vegetable greenhouse valve and opening of moisturizing pump assembly is stopped, and the PLC controller is gathered pressure sensor's analog signal and is carried out the comparison with the pressure setting value, through the frequency of PID regulation control converter to the water supply pressure of control working shaft unit reaches the purpose that the constant voltage was irrigated. The utility model discloses an effective effect is even watering automatically to ability real time remote monitoring has increased the flexibility of system, can also carry out the pesticide through this irrigation system and irrigate, has saved the manpower and the time of spouting the pesticide.
Description
Technical field
This utility model relates to constant irrigation and the tele-control system of agricultural irrigation, be a kind of integrate intelligent with artificial two kinds of control modes convenient, save time, the long-range constant-pressure irrigation system in labour-saving.
Background technology
At present, it is all based on man-made irrigation that agricultural greenhouse is irrigated, and needs substantial amounts of labour force, and inefficiency, easily causes and irrigates the situations such as the most uneven, thus causes yield the highest, and income reduces.Additionally when multiple booths need to irrigate simultaneously, but because hydraulic pressure deficiency cannot realize at all, contrary in the case of then can be because of the excessive waste causing water resource and the energy of hydraulic pressure.
Summary of the invention
The deficiency existed in view of above-mentioned present technology, this utility model provides booth vegetable constant irrigation control system, energy automatic irrigation and water pressure invariableness when booth needs to irrigate, irrigate uniformly, and energy real-time remote monitoring, more can select manual mode by remote supervisory and control(ling) equipment, directly control water pump pouring, nimbly and freely.Pesticide irrigation can also be carried out by this irrigation system, save manpower and the time of pesticide.
nullIt is by small pump unit 1 that this utility model solves its technical problem long-range constant-pressure irrigation system of the technical scheme is that booth vegetable、Cistern、Defecator、Electromagnetic valve 1、Small pump unit 2、Medicine pond、Electromagnetic valve 2、Feed pump unit、Pressure transducer、Electromagnetic valve 3、Booth A、Electromagnetic valve 4、Booth B、Humidity sensor 1、Humidity sensor 2、Liquid level sensor、Liquidometer、Remote terminal、GPRS telecommunication device、PLC、PID regulation and converter form，It is characterized in that: PLC and pressure transducer、Humidity sensor、Liquid level sensor is connected with liquidometer and gathers its signal，PLC and small pump unit、Feed pump unit is connected with converter and controls it and runs，Remote terminal is connected with PLC by GPRS telecommunication device，Finally realize long-range constant irrigation.
Effective effect of the present utility model is, can irrigate the green house of vegetables needing to irrigate, and energy real-time remote monitoring by automatic uniform, add the motility of irrigation system, it is also possible to carry out pesticide irrigation by this irrigation system, save manpower and the time of pesticide.
