Background

From the origin to the destination, different products need to be stored at different temperatures, so it is very important to control the temperature in the whole process. Cold chain is a protection system equips with special facilities and equipment to maintain low temperature environment for processing, transportation and storage of fresh agricultural and aquatic products. Meanwhile, cold chain logistics can also be applied in the field of medicine, for example, vaccine and precision medical instrument transportation.

WLINK Solution

Wlink uses the advanced IoT technology to provide an effective solution for cold chain monitoring: industrial grade wl-rt600 4G / 3G RTU, with a wide range of working temperature, - 40 ~ + 70 ℃, can work normally in the cold chain environment. This RTU provides RS-232 and RS-485 dual serial ports, and AI, DI ports, which are compatible with various temperature and humidity sensors, and sends real-time temperature and humidity data to the data center through 4G/3G network. In particular, WL-RT600 supports temperature and humidity threshold alarm. When the temperature of the cold chain vehicle exceeds the set value, the M2M platform of the management center will receive the alarm from WL-RT600, and the staff can immediately take corrective measures to ensure that the ambient temperature of the cold chain is maintained in the best range. The built-in GPS allows users to track the location of cold chain vehicles to ensure that they are driving on the scheduled route, so as to ensure the timeliness of goods distribution.
