This structure mainly contains three hierarchy of skills.Ground floor is bio-safety perception subsystem, this layer realizes detection boar growing environment and the correlation parameter of raising food, according to these parameter values and pig growth rule, regulate boar growing environment and conditioning equipment thereof, optimizing matching raises food, information-based monitoring and specification employee operation, form a complete Internet of Things management system, increase pig-breeding quality, fuzzy control and neural control combine by this subsystem, set up the FUZZY NERVE CONTROL MODEL of kind of piggery enviroment, solve the multivariate regulation and control problem of pig house environment; Introduce the FUZZY ALGORITHMS FOR CONTROL in Based Intelligent Control, the experience of feeding of keeper and existing expertise are combined together to form rule base of feeding, set up meticulous Controlling model of feeding; The second layer is boar growth conditions communication subsystem, thered is provided and quality assurance technology by the service flexibility of dynamic system environment, realize the intellectual monitoring of the condition indexs such as boar livestock on hand, all kinds of pig livestock on hand, public insemination of sows, and implement to prevent boar common disease; Third layer is boar pig information trace subsystem, adopt the scheduling of resource technology of procedure-oriented perception, realize boar to enter the population date, follow the tracks of at group's situation growth tracking control of full process and his father, mother and coefficient of inbreeding pedigree, realize the information of boar to boar growth overall process and carry out tracking storage, guarantee boar cultivation quality, improve boar cultivation efficiency, for food security and boar quality lay the foundation.
The present invention is starting point from the precise feeding realizing boar, target is turned to realize factory pig farm production management comprehensive information, with regard to plant pig farm produce involved by object and overall process carry out informationization and visual expression, design, monitor and managment, take modern information technologies as means, by infotech integrated pig farm information acquisition, information processing and Information application, make the breeding of modern information technologies and kind Pig Farm, breeding, feed and the effective integration such as nutrition, diseases monitoring, serve the structure of the thelematics platform of boar healthy aquaculture.From physics is disposed, as shown in Figure 2, according to actual boar cultivation distribution situation, boar bio-safety perception subsystem is arranged in pig house, Real-Time Monitoring environmental parameter and parameter of feeding, and the application server can networked by backstage is regulated and controled relevant device; The observing and controlling of boar health status is arranged on the believable third party's industrial computer of user, periodic detection boar health status, and carries out information interaction and renewal with backstage networking; Boar pig information tracking system is installed on boar pig ear, by sensing device, data message is passed to background server.
Bio-safety perception subsystem is architecturally divided into three modules: pig farm growing environment monitoring module, meticulous administration module and the turnover pig farm personnel tracking module of feeding in pig farm.Wherein, pig farm growing environment monitoring module detects the factor affecting environmental quality in pig house, and according to these factors, the concentrated messageization of index each in pig house is regulated and controled, the further environmental quality improving pig house, the comprehensive automation making it can realize poultry house environment controls, and can reach again the target of economize energy.Plant the information-based control methods of pig house environment, mainly utilize various sensor, comprise temperature, humidity, gas sensor or intelligent sensor etc. are as the pick device of information, host computer is transferred signals to by I/O interface and bus, there is the intelligent controller in host computer, by fuzzy calculation inference, each signal is carried out decoupling zero process, be about to main containing temperature, humidity, the variable such as ammonia and ventilation has the pig house environment system of coupling influence, dissolve into each non-coupling single-variable system, the environmental aspect in pig house is made to reach present situation needed for boar self, and show in LED display, and then make corresponding regulation measure, obtain best house environment.Temperature and ammonia concentration, the humidity etc. of pig house is regulated by heat generator and skylight, ventilating opening, wet curtain blower fan etc.Pig farm environment monitoring module as shown in Figure 3.
The meticulous administration module of feeding in pig farm can meet the supply of forage of whole pig house, by feeding self-actuated controller, feed in hopper is sent to each swinery automatically, avoids the personnel of feeding to introduce germ from the external world, thus reduce the probability of pig generation pestilence and disease.This module according to weight, age, the gestation of every boar, the concrete condition such as to breed, throw in corresponding forage volume, thus accomplish to carry out meticulous target of feeding according to individuality.First, computing machine is according to existing data, intelligent decision is carried out to each pig, according to fuzzy theory, show that today, this pig needed to eat how many feeds, then send signal to stepper motor, discharger is according to the signal drawn before, automatic input feed, by weight induction device, returns its actual gravimetric value.Its Based Intelligent Control principle as shown in Figure 4.
For guaranteeing that personnel will not carry germina infection to boar when passing in and out boar pig house, need to carry out tracing management to personnel in pig house.Turnover pig farm personnel tracking module adopts RFID radio-frequency (RF) identification location technology, detection personnel position.Computing machine is according to corresponding personnel positions, and whether make is that it enters the judgement of pig house.
The principle of RFID is that the electromagnetic wave utilizing frequency to be 50kHz ~ 5.8GHz carries out the communication of noncontact twocouese with unlimited RF-wise, to reach identifying purpose and to exchange data.The distance of radio-frequency (RF) identification can reach tens centimetres to several meters, and according to the mode of read-write, can the information of ship's speed multiple kilobytes, has high confidentiality simultaneously.RFID technique can work in various rugged surroundings, can identify high-speed moving object and can identify multiple label simultaneously.RFID technique has more outstanding advantage compared with bar codes technique: can identify single and concrete object, and can only identify a type objects unlike bar code; Owing to adopting less radio-frequency, data can be read through exterior material, and bar code can only be read one by one; In addition the RFID quantity of information that goes out to store also than bar code contain much information many, can be loaded with and close all kinds of relevant informations of object.The most basic rfid system forms primarily of two large divisions, as shown in Figure 5:
Electronic tag (Transponder also can be described as Tag): be installed on the object that is identified.The integrated circuit be generally made up of coil, antenna, storer and control element and chip.Each label has unique electronic code identified, and stores the information needing to identify transmission.Label is attached on object, under the effect of automatic or external force, the information stored can be sent.
Read write line (Reader): according to the difference of method for designing and operation technique, mainly can be divided into read-only (read), erasable (read/write) two kinds.It is primarily of compositions such as forwarder, receiver, control chip and induction installations.In addition, a lot of read write line can be equipped with extra interface, as RS232, RS485 etc., allows it by the data transmission that receives to another one system, as PC, control system etc.
In addition, system also should comprise some ancillary hardware facilities such as antenna, main frame.
After label enters magnetic field, if receive the special radiofrequency signal that read write line sends, the energy that just can induced electricity be relied on to obtain sends out storage product information in the chips (i.e. Passive tag, passive label or passive label or initiatively send signal (the i.e. Active tag of a certain frequency, active label or active tag), read write line reads to be believed and after decoding, then delivers to the process that information handling system carries out related data.
The operating scheme design of turnover pig farm personnel tracking module is as follows:
First, after personnel arrive pig house, be with label, by identification information the most basic for product write label, can be generally unique sequence number, also can be the code representing product related information field.After relevant product and label generate, by the record of correspondence stored in network shared data bank.
Then, by the label be embedded with in product, the real-time information of the personnel in pig house activity being gathered, then through extracting and conversion, being preserved into database by communication facilities.
Any stage of pig house is passed in and out personnel, the identification information stored in the electronic tag of interiors of products is read with rfid interrogator, just can obtain the various information of product in conjunction with network data base, realize the real-time follow-up to Product Status by relevant software systems.
Turnover pig farm personnel tracking module totality mentality of designing such as Fig. 6 shows.Electronic tag is the real data carrier of rfid system.Usually, electronic tag does not have oneself power supply pond, and only within the responding range of read write line, electronic tag is only active.Energy needed for electronic tag work is the same with data with time clock, is transferred to electronic tag by coupling unit.Electronic tag is normally made up of the microchip by memory function and the large-area coil as antenna.The basic task of read write line starts electronic tag exactly, communicates and transmit data with electronic tag between application software and electronic tag.Read write line has the function of read/write electronic tag.Communication interface is responsible for the communication of host computer (PC end) and slave computer (read write line).In general, communication interface has multiple feasible scheme, is employed herein RS-232 agreement, i.e. serial communication scheme.Have employed the application model of browser/server in system, computer terminal is used for the operation of employee, and is divided into application server and database server at server end, processes different software requirements respectively, provides efficient data processing.
Boar health status communication subsystem structure is according to the multiple health indicator factor of boar, the multiple technologies such as wireless technology, network technology and computing technique are merged, set up the dynamic measurement model based on interactive Markov chain, boar growth indexes is measured and monitored.This subsystem is architecturally divided into two modules: condition parameter monitoring module and boar disease forecasting module.Wherein, condition parameter monitoring module utilizes various sensor, comprises the pick device as information such as temperature, gravity sensor, monitors and record the pig self health status information such as body temperature, food of boar; The own health status information that these monitor by boar disease forecasting module is analyzed, and contrasts with known disease physiological status storehouse, thus realizes the prediction to boar health status, guarantees that boar is got timely medical treatment.
Boar disease forecasting module, as a kind of concurrent system analytical framework of capable of being combinedization, adopts orthogonal mode to combine classical interactive Markov chain (IMC) model---mark transition system (LTS) and performance model---Markov chain continuous time (CTMC).An IMC is defined as a five-tuple , wherein:
1) it is the state set of a non-NULL;
2) it is a set of actions;
3) it is action transfer relationship;
4) be that horse can husband's transfer relationship, meet ;
5) it is original state.
2 transfer relationships in definition are the action transfer in LTS and the stochastic distribution Branch-delay (Parametric Representation by exponential distribution) in CTMC respectively, and as shown in Figure 7, IMC model has following 2 features:
1) system can perform multiple possible action transfer in a state, as can in action between select.Because action transfer is separated with time delay, so the uncertainty that the selection between these actions transfer remains LTS is explained.
2) if transfer both can have been performed an action in a state, markov transfer can be performed again, as , then take maximum advance to suppose: the execution of internal actions (representing with τ) does not allow time delay, even has internal actions, then it performs is immediately, does not allow other Branch-delays to occur.External action (gather with represent, action wherein with a, b, c... represent) execution depend on environment, be likely delayed by, as if system does not perform an action (or carrying out interactive action with environment) within a certain period of time aor b, so system can be selected to perform markov transfer.
Credible dynamic measurement based on Markov chain comprises following 3 steps: describe the behavioral expectations of 1); 2) during system cloud gray model, evidence obtains; 3) behavior creditability checking;
1) describe behavioral expectations
IMC describes the feature of system from function and performance, therefore adopts the description realizing expection from function and performance perspective based on IMC, for credible dynamic measurement.Namely expectability will form expection to " how doing " on specific function behavior base, as complete specific behavior function time IMC in by the specific behavioral function of path representation, but introduce performance index in path, by path probability association expection, and by the path probability acquisition approach time, formed completing the expection of specific function behavior on temporal characteristics, as the module of performance index.Implementation method, namely by marking the state in IMC model, represents the credible execution route from this state.
2) when running, evidence obtains
The fundamental forming credible dynamic measurement platform evidence is behavior and attribute thereof, and behavior property should comprise time when behavior occurs here.By the describing mode portrayed in employing software action to a basic act, realize the acquisition to evidence when running.
3) behavior creditability checking
The core of Trusting eBusiness be by evidence during the operation obtained with behavioral expectations compare and provide asserting of behavior creditability.By extracting the behavior in evidence , and as the behavior time of origin of behavior property , at the given behavior metric base based on IMC under (i.e. behavioral expectations), behavior creditability is judged, if , then A is believable to behavior metric base BMIB.
Boar pig information trace subsystem adopts the scheduling of resource technical notes of procedure-oriented perception to follow the tracks of the data message such as birth record, breeding record, delivery log, pig house record, and traces to the source to boar pig pedigree.Whole boar pig information flow relates to numerous link, and each link comprises bulk information again, and all information is all recorded shortage feasibility.The information of tracing to the source is screened, the search request that the producer, regulator etc. are different can be met, optimization data storehouse, improve running efficiency of system.According to the method for " process analysis-key point controls ", adopt CCP decision tree in HACCP, is traced to the source a little as key in the crucial CCP reference mark in pig growth information.Trace to the source a little by key, according to enterprise need wait requirement, conclude and arrange out the security critical information in the stage of butchering.
Boar management process is introduced from boar and is started, and introduces to comprise inside and to select and remain or outside is bought, and what outside was bought also needs to quarantine, and herd boar enters " boar house " afterwards, and broad sow enters " breed and give up ".In the management of boar, every pig has unique overbit, and all management accounts all must associate with overbit.Existing boar growth management flow process such as Fig. 8 shows.And the present invention is on existing basis, adds intelligent boar and select.When breeding, by intelligent selection, select classic a collection of, then manually get essence.Then by there being the sow of pregnancy reaction to enter gestation house, if miscarriage, then breeding house is put back to.After childbirth, because all porklings differ, to establish a capital be boar, so fertility sow is sold or given over to sow after then growing, selects joining in boar troop of some stalwartnesses and go in boar son, and the just transaction eliminated is to raiser.
As shown in Figure 9, boar pig information trace subsystem is divided into three layers: client layer, operation layer and data Layer.Client layer provides the multiple inquiry mode of cell-phone customer terminal, browser and customized software.The system user such as the producer, regulator can apply the mode of query composition, query-related information, grasps the quality safety information of each link.Operation layer provides the major function of system, follows the tracks of review the large subsystem composition of subsystem seven primarily of pig growth information subsystem, pedigree information subsystem, RFID label subsystem and pork.Data Layer is divided into platform database and Service Database two parts, and platform database provides the service data of basic platform, and Service Database provides business datum.
Native system is traced to the source in Message Entry System database by each link of boar pig information flow, identifies, record management and tracking to the information of each link, forms a complete message sense.Pork operator and regulator can according to the grid platforms shared, and realize pork quality and follow the tracks of safely and review, meet the needs of safety in production.The life cycle of boar pig has: several processes such as piglet, one-tenth pig, pregnancy, lactation, commercialization, if the pig be eliminated in the ordinary course of things all can become market pig, also have certain dead probability.After childbirth, because all porklings differ, to establish a capital be boar, so fertility sow is sold or given over to sow after then growing, selects joining in boar troop of some stalwartnesses and go in boar son, and the just transaction eliminated is to raiser.
