What the deformation of greenhouse domes often occurred in vertical direction, therefore, set for the domes of greenhouse
Counted it is a kind of for monitoring the deformation monitoring device 1 of the deformation quantity occurred in 13 vertical direction of greenhouse arched framework, such as Fig. 2 institute
Show, which includes vertically disposed draw-wire displacement sensor 6 and horizontally disposed aluminium alloy lighter bar 7, and the aluminium alloy is light
The both ends of bar 7 are fixed on the side of greenhouse arched framework 13 by fitting repeatedly, preferably, as shown in figure 4, the company
Fitting uses clip 11, and one end of the clip 11 is fixed by screw and aluminium alloy lighter bar 7, while clip can be adjusted flexibly
11 are set on the outside of greenhouse arched framework 13 with 7 angle of aluminium alloy lighter bar, the other end of clip 11, and tight by tightening
The fixation of fixing bolt 12 realization aluminium alloy lighter bar 7 and greenhouse arched framework 13.The upper end of the draw-wire displacement sensor 6 is passed through
Not easily stretchable seizing wire 8 and the top for being fixed by screws in greenhouse arched framework 13, the lower end of draw-wire displacement sensor 6
By not easily stretchable seizing wire 8 and it is fixed by screws on aluminium alloy lighter bar 7.
When having a large amount of accumulated snow above greenhouse, will lead to greenhouse arched framework 13, deformation occurs in vertical direction, usually
Shape becomes skeleton since pressure is pressed downward bending deformation, when deformation occurs, shape on aluminium alloy lighter bar 7 and greenhouse arched framework 13
Become the distance of generation point and its vicinity in vertical direction to change, when the distance changes, as shown in figure 3, peace
The sliding of sliding block 10 of swept resistance 9 leads to resistance variations in the draw-wire displacement sensor 6 near DEFORMATION POINTS or DEFORMATION POINTS,
To which the deformation to greenhouse generates corresponding signal, realize to the deformation monitoring in 13 vertical direction of greenhouse arched framework.
When being installed to draw-wire displacement sensor 6, to be determined according to the specific structure of greenhouse arched framework 13, such as
Greenhouse arched framework 13 shown in Fig. 2, since the shed top radian of the type is smaller, when being not likely to produce accumulated snow, therefore installing
7 fixed point of aluminium alloy lighter bar be may be mounted at the 1/2 of 13 central point of greenhouse arched framework, also, collapsed by related greenhouse
The report of disaster is found in the news collapsed, the deformation in the greenhouse arched framework 13 of collapsing often at these locations is the tightest
Weight, therefore draw-wire displacement sensor is installed near 7 fixed point of aluminium alloy lighter bar is at 13 central point 1/2 of greenhouse arched framework
6 is more appropriate.Meanwhile the quantity of deformation monitoring device 1 uses two groups, the reason of being symmetrically mounted on two sides at frame center, exists
In often due to wind action, will lead to the snowpack of greenhouse two sides and different when encountering the heavy snow weather with wind
It causes, may be implemented more comprehensively to supervise 13 deformation of greenhouse arched framework using symmetrical structure installation draw-wire displacement sensor 6
It surveys.
The signal processor 2 connects one to one with deformation monitoring device 1, by 1 medium pulling rope formula position of deformation monitoring device
13 deformation signal of greenhouse arched framework detected by displacement sensor 6 carries out A/D transformation, converts analog signals into digital signal
It into CPU, is stored after CPU is handled, and tidal data recovering and transmission unit 3 is sent to by ZigBee wireless network.
The signal processor 2 uses the AD7799 chip of U.S. Analog Device company, which there is excellent performance to refer to
Mark fully meets the requirement of precision, and there are three input channels for each chip, are convenient for multiple displacement transducer signals
Acquisition.
The tidal data recovering and transmission unit 3 pass through the data of ZigBee wireless network timed collection signal processor 2, and
Cloud server 4 is sent to by GPRS network.The tidal data recovering and transmission unit 3 are using Microchip company
PIC24FJ64GA104-I/PT single-chip microcontroller.
The cloud server 4 receives the deformation data that tidal data recovering and transmission unit 3 are sent, and counts to data
It calculates, analyze and handles, the deformation data that each deformation monitoring device 1 measures is converted into deformation quantity storage in the database, it is real
Now to the real-time monitoring of greenhouse deformation situation.The cloud server 4 converts the data being collected into, due to what is be collected into
Data are not direct variable quantity, but the quantity of state at each monitoring moment, according to set after installation deformation monitoring device 1
Calculation of initial value go out it is each monitoring the moment the deformation quantity relative to initial value.The cloud server 4 selects Ali's cloud clothes
Be engaged in device ECS.
The client 5 shows the deformation data of different monitoring points in the form of a graph so that user for
Deformation quantity at different monitoring points can be got information about, and convenient for taking maintenance measure, the client 5 includes computer, mobile phone
Deng.
The deformation monitoring method realized based on one of the above greenhouse deformation monitoring system comprising the steps of:
Step S101 installs several groups deformation monitoring device according to the scale of greenhouse on greenhouse arched framework 13
1；
Step S102, several groups deformation monitoring device 1 are correspondingly connected with signal processor 2, are received by deformation monitoring device 1
Collect the deformation degree in vertical direction of greenhouse arched framework 13, signal processor 2 is by the deformation signal of greenhouse arched framework 13
Digital signal is converted into be stored；
Step S103, signal processor 2 are communicated by ZigBee-network and tidal data recovering with transmission unit 3, tidal data recovering
The monitoring data collected in a signal processor 2 with transmission unit 3 every 30~60 minutes, the data being collected into are passed through
GPRS network is transferred to cloud server 4；
Step S104, tidal data recovering are connect with transmission unit 3 and cloud server 4, and cloud server 4 is to the number sent
According to being calculated, being analyzed and being handled, obtains the deformation situation of greenhouse, i.e., monitor one after the installation of deformation monitoring device 1 is stablized
A basic value A monitors another value B when deformation occurs for greenhouse arched framework 13, and the deformation quantity for calculating generation at this time is B-
A。
When cloud server 4 handles the deformation data monitored, it is contemplated that expanding with heat and contract with cold for environment temperature is brought
PERIODIC INTERFERENCE, data are filtered；Simultaneously, it is contemplated that since the activity of people, birds and beasts etc. may be to monitoring
Deformation data generates interference, and this kind of interference is often nonlinear, uncertain, therefore carries out smooth disposal to monitoring data
After be supplied to user.
When tidal data recovering is communicated with transmission unit 3 and cloud server 4, sometimes due to communication failure will lead to some
The missing of monitoring node monitoring data, the integrality of the data of user is supplied to for guarantee, and local missing data needs to carry out
Fill up processing, common simple process method includes deleting missing data, with closing on the methods of data substitution, these complementing methods
Implement simply, but data useful information is easily caused to lose.The system uses support vector machine method when handling missing data
It is handled, support vector machines can be predicted according to data with existing, to obtain the data closer to true value, and then be adopted
Missing data is filled up with prediction data.
Step S105, cloud server 4 are connect with client 5, and client 5 is to the deformation situation of greenhouse with the shape of curve graph
Formula is intuitively shown.
Finally, it should be noted that embodiment described above, only specific embodiment of the present utility model, to illustrate this
The technical solution of utility model, rather than its limitations, the protection scope of the utility model is not limited thereto, although referring to aforementioned
