1. Application requirements
With the development of social economy and technology, the pig industry will achieve intensive, large-scale and high-density development. In order to improve the efficiency and benefits of pig breeding, the pig breeding industry urgently needs to be combined with automated, high-precision control and detection technology. The goal of pig farm environmental monitoring is to maintain a good pig farm’s internal environment, so that the pig farm can maintain ventilation, appropriate temperature and humidity, and good air quality.
1. The monitoring status of environmental temperature and humidity in domestic pig farms
After the reform and opening up, my country’s pig production has become the world’s largest. However, as a large country of pig breeding, there is still a certain gap between my country’s breeding efficiency and benefits compared with advanced countries. We should learn and learn from the advanced pig raising models and technologies abroad, take precise raising and efficient raising as the direction of our future work, and focus on the introduction of Internet of Things technology and automatic control technology into pig breeding to realize the monitoring of the temperature and humidity of the pig house environment. Management automation has enabled us to gradually narrow the gap with developed countries in terms of pig raising efficiency and benefits.
2. Application of automatic monitoring system for temperature and humidity of Zhongda Baixun pig farm
In a large-scale pig farm, the environment of the pig house, such as temperature, humidity, light, harmful gases, etc., have an important impact on the growth and production performance of pigs. Zhongda Baixun designed a temperature and humidity automatic control system based on the Internet of Things RFID technology in response to the slow growth rate and low slaughter rate caused by excessively high or low temperature and humidity. Using RFID electronic temperature and humidity sensor tags, wireless RFID readers, environmental monitoring workstations, real-time temperature and humidity monitoring and management of the pig farm environment. Through the communication between the controller and the system, control the operation or stop of boilers, fans and other equipment, realize the automatic adjustment of temperature and humidity in the pig house, and keep it under the best microclimate conditions required for the growth of the pig herd.
3. Principles for the construction of an automated monitoring system for temperature and humidity in the environment of Zhongda Baixun pig farms
Stability and reliability: The necessary precautions for the entire system, through the use of backup, disaster tolerance, fault tolerance and other solutions, provide good stability, ensure the uninterrupted operation and service of the system, and ensure the stability and reliability of the system.
Security and confidentiality: High security of the system and information must be guaranteed. Take necessary precautions to ensure the software and hardware safety of the host and network system; ensure the safety of system applications; ensure the safety of system data.
Ease of use: Use the most commonly used information tools to reduce the workload of training as much as possible.
Convenience: The wireless transmission technology is adopted, and the installation is convenient and fast; the whole environment is still tidy after the installation is completed.
Advancement: The system adopts internationally advanced, mature and practical technology, which not only guarantees the functions realized by the system, but also ensures that the technology of the system can still meet the needs of application development in the next five years.
Practicability: Design the system in combination with specific applications and actual conditions to meet various functional requirements to the utmost extent.
Real-time: The constructed system is a real-time and reliable platform, which guarantees the real-time of data transmission.
Economics: The construction of the entire system should consider the economics of investment; on the one hand, adopt advanced technology and equipment; on the other hand, consider protecting the interests of investors. In the program design, resources must be fully utilized to ensure the economy of system construction.
Compatibility: The system should use advanced and mature technology and standardized products to realize the openness of the system on the basis of standardization.
Scalability: The design and construction of the entire system fully consider the expansion needs of the host and network hardware, the needs of secondary development of the application system, and the needs of supporting new businesses that may appear in the future.
Maintainability: The management, maintenance and repair of the system are simple and maneuverable. The network platform, system software, and application software of the system provide convenient and flexible maintenance methods to facilitate maintenance and management by application personnel.
4. Zhongda Baixun pig farm environment temperature and humidity automatic monitoring system achieves results
After the Zhongda Baixun pig farm environmental temperature and humidity automatic monitoring system helps companies establish a unified application platform, it can ensure that pig breeding companies can transparently view and supervise environmental changes in pig houses, strengthen pig control, improve disease control capabilities, and improve Product quality, increase the scientific and technological content of products, and at the same time provide more scientific technical support for the establishment of a pig-raising resource gene bank, selection of good breeds, and improvement of the breeding system of good breeds.
Second, the implementation process
1. The data collection workflow of the environmental temperature and humidity automatic monitoring system:
Temperature and humidity labelThrough the set state, actively send temperature and time data to the environmental monitoring workstation, or send a read instruction from the environmental monitoring workstation to read the tag data, and store the records in the environmental monitoring workstation. The application server adopts a timed and cyclic scanning method to send data collection instructions to each environmental monitoring workstation, collect the temperature, humidity and time information stored in the environmental monitoring workstation, and transmit the data to the application system or database. When the collected temperature and humidity exceed the standard, the environmental monitoring workstation actively sends out instructions to control the operation or stop of boilers, fans and other equipment, so as to realize the automatic adjustment of temperature and humidity in the pig house and keep it in the best climate required for the growth of pigs. condition.
