With the improvement of living standards, people's requirements for environmental monitoring of breeding plants are getting higher and higher, especially for the monitoring of temperature and humidity indicators. Relevant departments have even incorporated this content into the assessment indicators. Due to the large number of detection points, the traditional temperature and humidity monitoring equipment and technology have been unable to meet the needs of refinement and diversification, which requires us to develop a multi-point, remote and convenient intelligent monitoring system in combination with modern science and technology. 智能畜牧养殖温湿度监控系统 ，限度地保证鸡舍等养殖区域环境温湿度符合生产、科研及生活的需要。 Chengdu Xinxin Electronic Technology Co., Ltd. uses scientific technology and combined with the actual needs of users to launch a wireless intelligent livestock breeding temperature and humidity monitoring system that is suitable for monitoring various types of livestock and poultry breeding environments to ensure the environment temperature and humidity in chicken breeding areas to a limited extent. Meet the needs of production, research and life.
System design basis:
● "JB / T5243-91 Industrial Control Computer System Acceptance Outline"
● "GB50198-94 Computer System Safety Guidelines", "GBJ93-86 Automation Instrument Selection Regulations"
● "HG20507-92 Code for Construction and Acceptance of Industrial Automation Instrumentation Engineering"
● "GB 50194-93 Safety Code for Power Supply and Consumption at Construction Sites"
● "GB 50054-95 Design Specification for Low-Voltage Power Distribution", "JJG874-2007 Temperature Indication Controller"
Third, the system architecture:
After on-site environmental investigation, combined with the functional requirements of the use department, the following system solutions were made specifically for XX company.
● Wireless temperature and humidity probe:
Used to collect temperature and humidity data at each monitoring point. On-site power supply, wireless transmission visible distance of 5 kilometers, local display.
● Wireless carbon dioxide sensor :
It is used to collect carbon dioxide data at each monitoring point, power on-site, wireless transmission visible distance of 5 kilometers, and local display.
It is used to collect ammonia gas data at each monitoring point, power on site, wireless transmission with a visible distance of 5 kilometers, and local display. Electrochemical sensor , high performance.
● Wireless intelligent monitoring DTU:
Receive data from various wireless sensors , centralized display to avoid manual inspection, touch screen settings. The terminal has a built-in GPRS module, which can remotely send data to urban offices. You can call early warning when the limit is exceeded.
● Host computer:
Used to run "Wireless Environmental Monitoring System Software" and store historical data.
● Intelligent controller:
When the received data exceeds the set upper and lower limits, the system software sends commands to the controller for linkage with the local exhaust fan to work. Realize unattended.
When the temperature and humidity data exceeds the limit, send a warning message to the specified mobile phone number.
● System software:
Comprehensive management of each monitoring point of the system, including data reading display, historical data query, chart curve display, function parameter setting, filtering, exporting and printing.
用户手机App： ● User Mobile App:
Access the data center through the smartphone app to view the real-time data on the site, and also to control the switching of the field equipment.
● Data collection:
Automatic data collection, recording and storage 24 hours a day.
● Real-time display:
The historical data can be automatically generated into tables, curves and graphics, and the image is intuitive.
● History storage:
Historical data is stored and backed up securely, and can be queried at will according to customer needs and filtering conditions. The data is exported and printed in various forms, and supports multiple formats such as PDF and Excel.
● Over limit alarm:
You can set the upper and lower limits of temperature and humidity by yourself. When the temperature and humidity exceed the limit, the display terminal and software interface will automatically prompt an alarm and beep on the LCD screen.
● SMS alarm:
When the alarm signal appears, the system can send alarm instructions according to the preset alarm cell phone and alarm conditions.
Five, system advantages:
● Collecting data:
Temperature accuracy can reach ± 0.3 ℃, humidity accuracy ± 2%, carbon dioxide ± 30ppm. Ammonia gas ± 3%.
● Wireless transmission reliability
Adopt 779MHz channel communication, wireless transmission has strong AES encryption function, strong anti-interference, and there are abundant communication channels to choose from.
● On-site installation convenience:
Wall mounting. No wiring is required for wireless collection points. On-site power.
● Centralized data display:
The sensor data of each detection point is sent to the intelligent DTU for unified display and transmitted to the computer of the management center for centralized display, which is clear at a glance, avoiding manual inspection and recording at regular intervals.
