Technical field

The present invention relates to salt pan leak detection technical field, in particular to a kind of salt pan based on environment technology of Internet of things is seeped Leak method for early warning and device.

Background technique

Traditional Salt production is to pour into seawater or subsurface brine in salt pond, is precipitated after being crystallized by natural evaporation former Salt, the process be unable to do without the effect in crude salt crystallizing pond, that is, salt pond.The bottom of pond of traditional crude salt crystallizing pond is the bottom of pond by will dig out Portion carries out simple smooth and pours into brine after rolling compacting and evaporate brine, the salt pond bottom of pond that this mode makes during evaporating brine inevitably There are the drawbacks such as spiced meats, phenomena such as waste so as to cause the spiced meats in salt pond.

In Solar pond production, Bittern of Salt Pan leakage is to assess an important indicator of salt pan quality；Salt pan leakage causes halogen Water resource utility model is that many sodium salts, sylvite manufacture the technical problem that encounters of unit.According to practical production experience, China Qinghai The percolation ratio in salt lake salt pan and Salt Lake in Xinjiang salt pan is about 0.5~0.8mm/d, and the loss of the potassium resource as caused by leaking reaches 20~50%, the brine of salt pan leakage is dispersed after permeating the ground, is absorbed, and is difficult to exploit recycling again；Salt pan leaks not The costs substantial increases such as stock number, the human and material resources for only causing unit product to consume, and cause the massive losses of resource.

Therefore, for cost increase and resources loss caused by the leakage of salt pan, it is anti-that technical staff has carried out a large amount of salt pan It seeps and studies and develop a large amount of salt pan seepage control technique.Most commonly used at this stage is clay mechanical ramming antiseepage, and clay has Particle is thin, is combined, the features such as plasticity is strong, and mechanical ramming can make the gap in soil texture reduce, enhancing compactness, Leakage is effectively reduced；This method has the advantages that construction is simple at low cost；And another effective anti-seepage method is plastic film shop fixtures Antiseepage, i.e., in the soil of salt pan bottom or surface spreads one layer of plastic foil and forms barrier layer, to prevent spiced meats, film used Material have PVC canvas or a PE plastic foil, plastic film shop fixtures construction is simple, it, since its adaptability is extensive, is salt that anti-seepage effect is ideal The technology that field antiseepage can use on a large scale.

But while seepage control technique makes constant progress, stagnation is but in for salt pan leak detection technology State；Existing salt pan leakage test mainly has needle water level gauge method and bell jar surveys infiltration method, and so-called needle water level gauge method is to use Probe touches the water surface of tested water level, but probe touches the depth of the water surface will affect measuring accuracy, and bell jar surveys infiltration method and is Salt bottom of pond portion is buckled in a bell-type drum surveys its local penetration amount and calculate whole milliosmolarity, but the method also has the selection due to measuring point And the factors such as depth of slotting cover bucket and influence its and survey the contradiction for seeping precision, while above-mentioned two method exists complicated for operation, is not easy to slap The disadvantage held.Therefore existing salt pan leakage detection method precision is poor, and it is special cannot to find that leakage region has become salt pan in time The long-term scientific research task of industry worker.

Summary of the invention

It is poor to solve the salt pan leakage detection method precision referred in above-mentioned background technique, leakage cannot be found in time Problem, the present invention provide a kind of salt pan leakage method for early warning based on environment technology of Internet of things, comprising the following steps:

Step S1, several salt pans to be measured are selected, and corresponding salt pan position is encoded；

Step S2, test chamber below salt pan is being corresponded to by being preset in the conductivity sensor test setting in each salt pan The conductivity of interior aqueous solution, obtains test data；

Step S3, by the conductivity test data real-time Transmission of aqueous solution in test chamber below salt pan to data center；

Step S4, the test data that data center will acquire is compared with preset standard scale, is judged whether It leaks；

Step S5, when test data is in standard scale, it is not necessarily to early warning；When test data exceeds standard figures model When enclosing, data center passes through the salt pan of exact p-value data source and issues warning information.

On the basis of above scheme, it is preferable that the conductivity sensor is DFRobot conductivity sensor.

On the basis of above scheme, it is preferable that the conductivity sensor passes through the solar energy that salt pan periphery is arranged in Mechanism energy supply.

On the basis of above scheme, it is preferable that further include the following test data processing side when salt pan leaks Method:

Step SS1, data variation curve is obtained according to the test data of acquisition, and constructs electrical conductivity of solution variation function；

Step SS2, electrical conductivity of solution variation function is changed over time into letter with the standard aqueous solution conductivity being previously obtained Number is compared；

Step SS3, it according to comparison result carries out judging whether to occur to leak and leak magnitude, and makes early warning.

The present invention provides a kind of salt pan leakage prior-warning device based on environment technology of Internet of things, is included in below salt pan and is equipped with Test chamber, the test chamber are connected to by sense channel with outside, on the passway outside sense channel connection Equipped with the conductivity sensor for detecting the aqueous solution conductivity variations situation being full of in test chamber and sense channel.

On the basis of above structure, it is preferable that be provided with data transmission device in the conductivity sensor.

On the basis of above structure, it is preferable that there are two sense channel, the detection is logical for connection on the test chamber Road is equipped with conductivity sensor in external passway.

On the basis of above structure, it is preferable that described two sense channels are arranged at the diagonal position in salt pan.

A kind of salt pan leakage method for early warning and device based on environment technology of Internet of things provided by the invention, with the prior art It compares, has the advantage that the salt pan leakage method for early warning using provided by the invention based on environment technology of Internet of things, on the one hand Since there are biggish conductivity differences compared with salting liquid for aqueous solution, when brine leaks in salt pan, by detecting water Electrical conductivity of solution can fast and accurately judge the case where salt pan is with the presence or absence of leakage；On the other hand, when salt pan leaks, The presence of the test chamber can also avoid to a certain extent salting liquid from directly penetrating into soil, cause destruction and the brine of soil The loss of resource.
