Automatic stereo library Introduction to Xueyi Refrigeration in Cold Storage
1、 Current situation and main problems of cold storage management
01. There are many temperature classifications in the cold storage, different working temperature ranges, strong professionalism and difficult management; 02. The switch of the cold storage system is manually operated, which brings great work intensity to the management of large areas and multiple warehouses; 03. Manual patrol is adopted for the management of the cold storage. It is often found that the patrol is not in place, the hidden trouble cannot be found, and the refrigeration system cannot be monitored for 24 hours; 04. The failure of refrigeration system equipment in the cold storage can not be found in time, resulting in increased consumption of food, drugs, etc; 05. The actual temperature of the cold storage and the data of equipment operation status cannot be collected in real time, the process temperature cannot be reflected in the production and storage process of goods, the food and drug storage environment cannot be guaranteed, the quality inspection cannot reach the standard, and high-quality goods are lack of persuasion and credibility.
2、 "Centralized monitoring, centralized maintenance and unified management"
01. It mainly monitors the temperature, humidity and carbon dioxide field of each cold storage, and transmits the data to the monitoring center through the wireless communication network in the form of GSMGPRS through the measurement and control terminal.
02. Through the remote measurement and control system, the maintenance personnel can query the operation status of the cold storage in real time, and realize the centralized management of the cold storage in multiple areas.
03. The monitoring center realizes the functions of real-time processing, analysis, storage, display and output of monitoring data, processes all alarm information, records alarm events, and sends control commands from background management personnel to each cold storage.
3、 System overview:
Value embodiment:
01. Reduce the work intensity of the cold storage manager
02. Start and stop the refrigeration system on demand, save energy, efficiently manage real-time monitoring, send fault alarms in multiple ways to report equipment status in real time, the refrigeration system is monitored 24 hours in real time, and potential faults are timely forewarned 03. Reduce the loss of food, medicine and other storage
04. The data of the actual temperature of the cold storage and the running status of the equipment are collected in real time to improve the persuasiveness and credibility of the commodity quality. The data is gathered to the measurement and control terminal through the temperature, humidity and carbon dioxide sensors in each cold storage room. The measurement and control terminal sends the data to the monitoring center through the GSMGPRS wireless network. The monitoring center realizes the centralized management of different cold storage. In case of equipment alarm, the alarm information will be transmitted to the mobile phones of system maintenance personnel and cold storage management personnel in real time through the measurement and control terminal or monitoring center.
System composition: the system consists of sensors, audible and visual alarms, measurement and control terminals, and monitoring center 01. Sensors and audible and visual alarms are installed in the cold storage to monitor various indicators of the cold storage environment and give on-site alarms in real time; 02. The remote measurement and control terminal is mainly used to monitor the temperature and carbon dioxide density of the cold storage workshop in real time. It can manage the temperature and carbon dioxide density through the monitoring center for 24 hours. When the temperature and carbon dioxide density reach the threshold, the remote measurement and control terminal can trigger the audible and visual alarm, At the same time, the remote measurement and control terminal will upload the real-time information of the cold storage workshop to the monitoring center through GPRS network and automatically send a short message alarm to the set mobile phone of the maintenance personnel.
03. The monitoring center is responsible for receiving, filtering, storing, processing, statistical analysis of data and providing real-time data query and other tasks, so as to know the environmental index of each cold storage workshop in real time. In case of emergency events such as too high or too low temperature and carbon dioxide density, maintenance personnel can directly see the alarm information of each cold storage workshop through the monitoring page.
4、 Software platform functions
01. Electronic map: visually display the operation status of cold storage equipment;
02. Management permission: set permissions in groups to ensure system security; 03. Cycle setting: The system administrator can flexibly set the cycle to ensure the real-time data of the monitoring center; 04. Alarm management: current alarm, historical alarm, alarm statistics; 05. Report statistics: alarm data statistics report, polling data statistics report; 06. Log management: user login and exit, parameter modification, alarm forwarding, etc; 07. Import and export: historical data is imported and exported in various forms (excel, txt, html).
