Two, technical background

In the prior art, comprise that the wireless remote control valve in the automatic irrigation system is actually a kind of valve that is driven by very narrow electric pulse, determined the action that opens or closes of valve by the both positive and negative polarity that changes electric pulse, the back is finished in action just no longer needs electric energy to keep current state.Control this class valve general valve positioner adopt signal cable, infrared ray, wireless station's control information transmission, its communication mostly is unidirectional, therefore can not gather out of Memory.And both-way communication also can make power consumption increase along with the increase of communication distance, and the power pack complexity increases cost and also increases greatly, thereby can not adapt to the needs of valve control in enormous quantities, low-cost.

Three, summary of the invention

Goal of the invention of the present utility model is, proposes a kind of valve positioner with double-direction radio data-transformation facility, and it utilizes the wireless telecommunications of little power consumption to carry out valve switch control and state, parameter are transmitted, i.e. micropower valve wireless controller.

Goal of the invention of the present utility model realizes by following measure, also fixedly valve position feedback interface, analog quantity are monitored interface, valve driving interface with the outside in the housing, fixing central processing unit also in the housing, voltage regulator circuit and battery and wireless communication line and antenna, wherein central processing unit is connected with battery, wireless communication line and antenna with control panel, valve position feedback interface, analog quantity monitoring interface, valve driving interface, voltage regulator circuit respectively.

The utility model is a kind of double-direction radio data-transformation facility (irrigating special-purpose) valve positioner that has, and it can accept the steering order that higher controller is sent through radio, can send information such as valve position state simultaneously by radio to higher controller.Whole device is controlled the following most of the time at the built-in timer of central processing unit and is in dormant state, only carries out service intermittent in little time, thereby has saved electric energy greatly, has prolonged battery serviceable life.This valve positioner is specially adapted to a large amount of valve controls that disperse, as irrigating control.

Five, embodiment

Embodiment 1: housing 3 surfaces are control panel 2 fixedly, also fixedly valve position feedback interface 5, analog quantity are monitored interface 8, valve driving interface 7 with the outside in the housing 3, fixing central processing unit 4 also in the housing 3, voltage regulator circuit and battery 6, wherein central processing unit 4 is connected with battery 6, wireless communication line and antenna 1 with control panel 2, valve position feedback interface 5, analog quantity monitoring interface 8, valve driving interface 7, voltage regulator circuit respectively.

The utility model embodiment realizes necessary function by the hardware and software acting in conjunction.Its principle of work is as follows: whole device is controlled the following most of the time at central processing unit 4 built-in timers and is in dormant state, only carries out service intermittent in little time, thereby has saved electric energy greatly, has prolonged battery serviceable life.The solenoid valve quantity of control is preferably one to four.

Central processing unit 4 is Once you begin worked and will be converted the actual opening valve off status to numerical information by valve position feedback interface 5, and converts controllers such as cell voltage self running parameter and other external parameter to digital signal and preserved by analog quantity monitoring interface 8.In a single day wireless communication line and antenna 1 receive the radio control instruction from the higher level, these instructions will be passed to central processing unit 4 with digitized electric signal, central processing unit 4 is separated the content that reads instruction, and according to the content control valve driving interface 7 of instruction, thereby the unlatching of by-pass valve control or close.Then the valve control action is finished information and the valve state that has monitored and inside and outside parameter and sent to higher controller by wireless communication line and antenna 1.

Because power unit of the present utility model adopted voltage regulator circuit, so can adopt the form that dry cell, rechargeable battery or solar cell are powered separately, also rechargeable battery and solar cell are united power supply, dry cell and solar cell combination power supply.
