1、 Industry situation

In order to maintain the good quality of the stored goods and create a suitable storage environment, it is necessary to monitor the temperature and humidity of the storage environment. Once the temperature and humidity of the storage environment are not conducive to the storage of goods, effective measures should be taken to adjust the temperature and humidity in the warehouse. Therefore, the establishment of a real-time temperature and humidity monitoring and early warning system and the preservation of complete historical data become the key in the storage industry.

As a smart Internet of Things terminal solution service provider integrating R&D, intelligent manufacturing and sales in the Yangtze River Delta region, Mantu Technology focuses on the monitoring and early warning needs of the storage environment. The temperature and humidity monitoring and early warning system based on LoRa wireless communication technology is a storage oriented environment launched by Mantu Technology 7 × 24-hour, real-time and comprehensive monitoring system; It is widely used in laboratories, medical storage, cold chain freezers, museums and other fields.

3、 System principle

The temperature and humidity monitoring and early warning system of diffuse technology based on LoRa wireless technology uses diffuse LoRa collector and LoRa gateway to achieve full coverage in the monitoring area. At the same time, diffuse temperature and humidity sensors are installed at each data acquisition node in the storage area to achieve dynamic full collection of temperature and humidity data in the monitoring area, and monitor, collect, transmit and early warning temperature and humidity data according to the actual needs of the storage environment. After the data is transmitted to the MTIC 3.0 platform, it is analyzed and optimized, and then precisely promoted to the WEB service system or mobile APP to achieve real-time monitoring, scheduling control, etc.

4、 Scheme features

● Real time data collection: collect the data of each monitoring point in real time and transmit it to the diffuse "Industrial Cloud Brain" MTIC 3.0 cloud platform for data analysis and dynamic display through big data billboards.

● High security and reliability: the system can effectively prevent illegal access, illegal access, virus infection, hacker attack and other network attacks, and has high security and confidentiality; The system adopts mature, stable and universal technologies and equipment, which can ensure the long-term stable operation of the system, and has strong fault tolerance and system recovery capabilities.

● Early warning and intelligent analysis: the data collected in real time can be compared with the set threshold to give early warning, leaving enough time for relevant disposal personnel to eliminate potential safety hazards.

● Historical data statistics: the second, minute, hour and daily historical data of each monitoring point can be recorded in a separate file in the monitoring node, so that the historical curve can be viewed more quickly. The historical and real-time data of the point can be browsed in the data record curve at the same time. The small interval unit of the historical record is seconds, and the statistical classification and storage are carried out according to different display methods, so as to ensure that there is no need to recalculate when viewing the annual report, Increase display speed.
