Breeding link

Raw sheep breeding is divided into different stages such as breeding, pregnancy, young sheep, and finished sheep

One is that rams and ewes can be dynamically managed by wearing RFID electronic ear tags, including information on breeding, pregnancy, and baby-bearing information, etc.

Secondly, when the lambs are born 30 days later, they will receive the first vaccine and health care. At the same time, they will wear colored RFID electronic ear tags that distinguish males and females, and associate the lamb’s ewe and their parents with the electronic ear tags. In the process, the breeder uniformly writes the feed feeding information, epidemic prevention information, medication information, and environmental information of the young sheep and the finished sheep into the RFID electronic ear tags of the pigs, cattle and sheep through the information platform or PDA, and uploads the data to the enterprise cloud through the network Platform data center, and establish complete individual sheep breeding files in the data center

Third, when the lambs are 50 days old, they will come out of the ewe pen, and the lambs selected as breeding lambs will be raised permanently (self-retained and cultivated), and other lambs will be transferred to the breeding shed to continue feeding into finished mutton lambs.

Factory link

When the finished mutton is loaded into the car, the UHF reader installed above the entrance of the breeding factory can automatically read and count the RFID electronic ear tag information of the finished mutton, and automatically record the time of delivery and other information. (And the factory flow information is entered in the PDA or background input when loading the car, and the illegal or under-factory conditions will automatically alarm when the sheep passes the gate) and upload the data to the enterprise cloud platform data center through the network, and the system will automatically save the factory information In the corresponding finished sheep file database for follow-up traceability and to provide the initial basis for the financial accounts of the breeding stock improvement center.

Mobile handheld terminal PDA office

Develop application modules for breeding, feeding, quarantine, quarantine, and data query on the mobile handheld terminal PDA; feeders or quarantine personnel can directly use the handheld terminal to operate when they raise sheep every day or perform quarantine and quarantine, and the data can be wirelessly operated. The network connection is automatically synchronized and imported to the security traceability database center.

Data collection based on RFID

RFID radio frequency technology is a non-contact automatic identification technology, which automatically recognizes the target object and obtains related data through radio frequency signals. The identification work does not require manual intervention and can work in various harsh environments. Compared with barcode technology, RFID can save more time, manpower and material resources, reduce production costs, and improve work efficiency. The advantage is that it is not limited to the line of sight, the recognition distance is farther than the optical system, the radio frequency identification card has the ability to read and write, can store a large amount of data, and has a certain degree of intelligence, which is difficult to forge.

This system manages the birth, breeding, and delivery of pigs, cattle, and sheep through the use of UHF pig, cattle and sheep ear tags containing RFID chips. In each process, various information about the sheep is recorded through ear tags, and through the use of handheld or non-mobile devices. The card reader collects data, and finally realizes the information traceability of pigs, cattle and sheep.

Basic data management

Basic data management refers to the initialization of some basic data used in the business management process. These data run through the entire business process. After initialization, the data needs to be used in the business module to directly select it. Basic data management includes sheep house management, employee management, ear tag management, camera management, feed information management, drug information management, etc.

Sheep shed management

Sheep shed management is used to manage the shed information of all the breeding farms under the breeding stock improvement center. The parent of the shed is the building number. The breeding stock improvement center needs to create a building number for all the sheep sheds, as well as for each sheep building. All sheep sheds are compiled with a shed number. After editing, write the number on the wall of each sheep shed, and then enter the information in this module of the system. The administrator can add new information to the data. Modify, delete and other operations. The card of the building number is an ultra-high frequency hard card that prints the LOGO information of the breeding stock improvement center. The card stores the related information of the shed and sheep breeding in the sheep house of the building. It can also be used to manage the breeding and fighting of the entire sheep Vaccines and other tasks are also convenient for the leaders of the Breeding Animal Improvement Center to bring hand-held equipment for inspections from time to time.

Staff management

Employee management is used to manage the information of all employees in the breeding stock improvement center. The system administrator can add, modify, and delete member information.

Ear tag management

Ear tag management is used to manage the information of all ear tags purchased by the breeding stock improvement center. When ear tags are purchased, they are marked with numbers. The system operator needs to manually enter these numbers into the system through this module. Of course, the process of entering ear tags can be carried out at the same time as the process of using ear tags. When ear tags are used, only the ear tags to be used are entered, and the data is written into the ear tags through the tag reader. Once the ear tag is used, it is bound to a specific sheep. As long as the number on the ear tag (of course the number is also stored in the RFID chip in the ear tag), all information related to the sheep can be queried.

Feed information management

Enter the feeding information of various feeds into the system for management, and directly select the type of drink to be fed in the feeding management. System operators can add, modify, and delete member information.

Drug Information Management

Enter the information of various drugs that may be used in the growth process of the black sheep into the system for management, and directly select the type of drugs used in the epidemic prevention management. System operators can add, modify, and delete member information.

Breeding management

Breeding management is the most important functional module in the system. This module will manage all the affairs of sheep in the entire breeding process.

Ewe Management

Ewe management is to manage those ewes that are used to conceive and give birth to lambs. The system needs to record the corresponding ear tag numbers of these sheep, the number of the sheep house where they live, the food information fed during the breeding process, the medication information, and so on. The system operator can add, modify, delete and other operations on this information.

Breeding (ram) management

Sheep management is the management of high-quality rams used for breeding. Just like ewe management, the system needs to record the corresponding ear tag numbers of these sheep, the number of the sheep shed where they live, the food information used during the breeding process, the medication information, etc. .

Breeding management

Breeding management includes two parts: breeding plan management and breeding management.

Breeding plan management is a plan drawn by the laboratory through scientific calculation of which ram and which ewe mate best. The plan information is entered into the system and the staff will implement it according to the plan when it is to be bred.

Breeding management is to manage the actual breeding situation, the information includes ram number, ewe number, mating date, etc. The actual operation is that the staff read the ear tags of the rams and ewes through the handheld when the sheep are mated, and then confirm them through the client software interface of the handheld. After confirmation, the data will be sent wirelessly to the server, and the management can use Visit the web to query this information.

Sheep management

Lamb management refers to the lambs that have not been assigned to the shed not long after they were born, and these sheep are still in the mother’s shed. The source of this information is that the lamb of the mother sheep’s birth will be recorded here by the staff. By entering the number of the ewe and the total number of sheep born, the system will generate a string of new numbers for each lamb by default. . After 30 days, the lambs should be treated for the first epidemic prevention, and the sheep should be earmarked and classified by gender. At this time, the information of these lambs needs to be updated, such as the gender of the sheep, the ear tag number, and the epidemic prevention information. Wait.

Growing sheep management

Breeding sheep management is used to manage sheep that have been allocated sheep sheds. In this module, you can query all the sheep’s information, including parent number, sheep shed number, date of birth, weaning date, feeding status, epidemic prevention, etc. Wait. You can search based on the mother’s ID number, sheep house number, ear tag number, etc.

Feeding management

Record the feeding situation after each feeding of the sheep. When recording this information, you can operate in batches according to the building number. The operation can be operated through the computer or the handheld client.

Epidemic prevention management

Record the epidemic prevention situation after every epidemic prevention of sheep. When recording this information, you can operate in batches according to the building number. The operation can be performed through the computer or the handheld client. If the sheep in a sheep shed are not quarantined in one go, select the building number first and then check all the sheds downstairs that have been quarantined.

System Management

System management includes functional modules for system maintenance, and the main function is to complete the task of system maintenance at the bottom. Included functions are: user management, authority management, data management, system log, role management, data dictionary items.

System management plays a very important role in software development. Whether the software can run normally or not is decided here. If this part is not done, the software will not run normally; at the same time, this is the first pass for software security. Without this part of the software, there is no security to talk about. Due to the importance of status, this part has always been the focus of software development, and it is also the most stable and mature part of software development. The reason for saying this is that every set of software has this part from the beginning of software development. Some of the functions are basically the same and the maturity is basically the same.

User Management

The ultimate purpose of any software is to provide people to use, so the personnel organization is the foundation of any software. We are here to extract personnel and institutions separately as a system to maintain. A variety of personnel are involved in this module, each of which belongs to a different system. As the data of the system is open to the outside world, the browsing right is not open to the maintenance right, so certain permissions and terminals are required to maintain the data. In this plan, the Breeding Animal Improvement Center has the right to modify the collected data and all the farms under its jurisdiction have no right to modify, and only have the right to query and browse, to ensure the completeness and accuracy of the data.

Role management

Based on RABC’s three-level authority management, the most important link is role management. The establishment of different roles and the assignment of permissions based on the roles greatly improves the flexibility and work intensity of authority assignment, and also meets the three-level permissions of the system. manage.

authority management

Resource management is responsible for maintaining the various resources of the system that require authorization processing, including various operations such as addition, modification, deletion, and viewing, as well as the data filtering function based on row level and the data filtering function based on page components.

Module management

Dynamic management of all modules in the system.

Data Dictionary

Setting of some constant data used in the system

Operation log

Check the operation log in the system, and the system will record all operation logs after each user logs in to the system for tracking and querying and guaranteeing the operation safety of system data.

data backup

Data backup is a protection method adopted to ensure data security. It is a process of retaining data in a certain way so that it can be reused in the event of system damage or other specific circumstances.

Data backup is an important part of the storage field, and its status and role in the storage system cannot be ignored. For a complete IT system, backup work is an essential part of it. Its significance is not only to prevent the destruction of accidents, but also the best way to preserve and archive historical data. In other words, even if the system works normally without any data loss or damage, the backup work is still of great significance-it provides us with the possibility of historical data query, statistics and analysis, and important information archiving and preservation.

Mobile handheld PDA client system

Breeding module

When the staff is doing breeding work, they use the handheld PDA to scan the ear tags of the rams and ewes. The breeding confirmation message pops up in the client system. After the staff clicks on the confirmation, the breeding information is uploaded to the data center.

Feeding module

After feeding a sheep house each time, the staff scans the building label at the door of the sheep house through the handheld PDA, or directly selects the number of the sheep house on the interface, and clicks confirm after selecting the food information to be fed.

Epidemic prevention module

After every time the staff has done epidemic prevention on the sheep in a sheep shed, they scan the floor label at the entrance of the sheep shed through the handheld PDA, or directly manually select the number of the sheep shed on the interface, select the drug information used for epidemic prevention and click Confirm That’s it. If a complete sheep shed is not done for one epidemic prevention, then the user can check the number of the sheep stall that has been quarantined downstairs in the system interface.

Quarantine module

Pigs, cattle, and sheep need to be quarantined before processing, and the quarantine personnel will complete the quarantine process after scanning with the handheld device and clicking the confirm button.

Data query module

This module is used to query various information, by scanning ear tags or manually entering the number to query various information related to sheep, such as breeding information, feeding information, epidemic prevention information, and so on.
