Description

A kind of agricultural irrigation sprinkler rate of utilization updating device

Technical field

The present invention relates to field of agricultural irrigation, particularly relate to the field that a kind of agricultural automation is irrigated.

Background technology

The networking of agricultural irrigation systems and informationization have become the objective requirement and inexorable trend that realize agricultural irrigation operation management modernization, the networking of agricultural irrigation systems is the basis of agricultural irrigation integrated dispatch commander, realize informationization on this basis, China's agricultural irrigation systems operation management will be made to enter centralization, the intelligentized New Times, the combination of computer technology, the communication technology and control techniques and developing rapidly, will promote this process jointly. Ethernet technology is guaranteeing its real-time transmitted, reliability and determinacy aspect obtain and develop on a large scale very much, it is in message capacity, the huge advantage of the communication aspect such as speed and configuration deployment, the communicating requirement of major part Industry Control system (such as agricultural irrigation Controlling System) can be met, in recent years, Ethernet technology combination technology (comprises agricultural irrigation Control System NetWork) in Control System NetWork and is widely used, have employed in a large number in network and compare proven technique, but how to go to identify the sprinkler highly used by high-tech means, thus carry out emphasis maintenance.

According to above problem, the present invention is compared to conventional traditional way, and safety boundary is more accurate, sprinkler maintenance no longer relies on the method that artificial hand strikes ear and listens, and consumes artificial resource less, starts with the time of response almost nil, therefore, the present invention has more advantage in agricultural irrigation.

Summary of the invention

The technical problem to be solved in the present invention is: under novel agricultural runs. The safety analysis accuracy of more complicated signalling set and even more sprinkler maintenance.

The present invention provides following technical scheme: comprise; Sprinkler maintenance responding device, sprinkler maintenance sends telltale; Wherein sprinkler safeguards formula:

$I_{ij}=\frac{\sqrt{a_i{b}_i}\×\sqrt{a_j{b}_j}}{R_{ij}^c}$

I in formula_ijRepresent the damage rate size between sprinkler, a_i,a_jRepresent plant growing rate between two sprinklers respectively; b_i,b_jRepresent the rate of utilization of sprinkler respectively;

Representing the damage possibility between sprinkler, wherein c is sprinkler wear rate, and this is generally drawn by model training;

Embodiment

In order to make technical problem to be solved by this invention, technical scheme and useful effect clearly understand, below in conjunction with drawings and Examples, the present invention will be described in detail. It should be noted that specific embodiment described herein is only in order to explain the present invention, being not intended to limit the present invention, the product that can realize said function belongs to equivalent replacement and improves, and is all included within protection scope of the present invention. Concrete grammar is as follows:

Embodiment 1: comprise; Sprinkler maintenance responding device, sprinkler maintenance sends telltale; The formula of sprinkler can be analyzed the average degree watered for agricultural and increase year by year, and quantity gets more and more, and it is more and more higher that agricultural sprinkler damages frequency. Within 2015, the average degree in the agricultural experiment field of Anqing is 279, and namely each agricultural sprinkler average and other agricultural sprinkler have 279 agriculture sprinklers to contact. The average path length of agricultural sprinkler network reduces to 2.78 in 2015 year by year from 5.99 in 2007, and any two agriculture sprinklers only need by less than once contacting, maintenance difficulties promotes. Improving and the kind of plant growing being increased along with agriculture network, in network, the connection of plant node is more and more higher, changes to convenient between plant. The angle value distribution of the agriculture sprinkler network in each year all meets power-law distribution, shows significantly " long-tail distribution " feature. This kind of network " long-tail distribution " feature shows that agricultural irrigation network is taking the big output plant of minority as core, and different plant experimental fields has the complex network of closely association feature, and the big plant experimental field of minority has more irrigates selection. Angle value spatially presents along agricultural main line distribution, is obviously collected in the Plains, the middle and lower reach of Yangtze River such as Beijing-Shanghai Kazakhstan, the North China Plain, Northeast plain. Along with the development of agricultural, angle value spatial distribution presents polarization trend, concentrates to the big plant hinge of minority gradually, and the development of the flora along with developed area, the plant variety that angle value is higher has occurred. Presenting equiblibrium mass distribution close to centrality, the agriculture sprinkler all having proximity values higher is in the differentiation of space. In the information age, agricultural sprinkler can cross use plant can also rely on artificial means, if Beijing, Zhengzhou, Wuhan etc. are with the plant in field near core. Along with the development of agricultural and the change of irrigation organizational form, the plant high close to centrality is concentrated to central and east provincial capital plant gradually; In the agricultural modernization epoch, the plant that agricultural sprinkler proximity values is high is mainly distributed in the city of the central and east. On national scale, the overall betweenness centrality of sprinkler is in rising trend, and the adjustment along with the perfect of agriculture network and out-of-season plant is described, the damage rate of sprinkler improves. Along with agricultural is in the development of the various transgenic plant of development, sprinkler betweenness centrality is relatively more outstanding, and after implementing new technology, the control action kou that sprinkler is used in agricultural irrigation is strengthened. Proximity values weighs elephant to the inverse of the shortest distance sum of all nodes with given node. So obtaining following sprinkler to safeguard formula:

$I_{ij}=\frac{\sqrt{a_i{b}_i}\×\sqrt{a_j{b}_j}}{R_{ij}^c}$

I in formula_ijRepresent the damage rate size between sprinkler, a_i,a_jRepresent plant growing rate between two sprinklers respectively; b_i,b_jRepresent the rate of utilization of sprinkler respectively;

Representing the damage possibility between sprinkler, wherein c is sprinkler wear rate, and this is generally drawn by model training;

Inventive design advantage mainly contains: with bursty state and communicates with the state of various equipment according to the state of agricultural irrigation according to actual operation, thus improves the reliability of agricultural irrigation.
