The most important thing in cold chain transportation is temperature control during transportation. Temperature monitoring is controlled by a thermostat. Long-distance transportation is generally equipped with a GPS temperature monitoring system, and temperature changes can be seen in real time in the office.
Usually refrigerated trucks or freezers. However, during transportation, in order to save fuel, drivers often turn off refrigerated equipment, which leads to deterioration of goods, especially in refrigerated transportation of medicines, which is the most dangerous. The cold chain temperature control device can be widely used in real-time temperature monitoring business in cold chain logistics and transportation in various industries. In recent years, there have been serious problems in the cold chain transportation of vaccines in some parts of the country. Taking the cold chain transportation of vaccines as an example to illustrate the typical industrial application of the real-time temperature monitoring system for cold chain transportation.
Vaccines are a relatively special commodity. They have strict requirements on the ambient temperature for storage and transportation. The failure of many vaccines is difficult to identify directly from the senses, which is doomed to the concealment of the problem and the difficulty of identification. At this stage, my country still lacks effective cold chain logistics management methods. The original monitoring technology is lagging behind, manifested as manual measurement and paper records; no unified data system support; poor real-time performance, disconnected supervision; difficulty in obtaining evidence, inability to determine responsibility, and inability to carry out early warning. At present, China's laws and regulations related to cold chain technical specifications and regulatory standards for pharmaceuticals are in the process of formulating, and it is a general trend for vaccine cold chain to enter the field of supervision.
The content of cold chain data includes basic information of vaccines, basic information of cold chain equipment and its maintenance records, basic information and maintenance records of monitoring equipment, and basic information of cold chain managers. According to the running direction of the vaccine cold chain, the cold chain transportation control device is produced by the starting point manufacturer, moves to the inoculated population in a branched distribution form, and finally reaches the inoculated person. According to the current status and management characteristics of vaccine cold chain, continuous data of vaccine cold chain is very important, and continuous cold chain data is the source of information required for vaccine cold chain management. The temperature information in the vaccine cold chain is the core data, while other information is auxiliary data. The quality change of the vaccine is judged according to the core data, and the external environment and the responsible person when the temperature changes are judged according to other data. If the cold chain data of the vaccine is found to be incomplete or out of the cold chain during immunization at the end of the cold chain, there is a basis for judging whether the vaccine is damaged. And the responsibility can be determined according to the data such as the time, place, and responsible person, which provides a basic guarantee for the entire cold chain management.
According to the characteristics of vaccine cold chain management, the Internet of Things technology is used to monitor the entire link from production, transportation to terminal without dead ends. Once an abnormality is found, an alarm will be issued in time to notify the relevant personnel to take corresponding measures, thereby reducing the failure of the vaccine. When a vaccine cold chain accident occurs, it can be determined that the vaccine has deteriorated and it can be detected and destroyed, so as to avoid the occurrence of the accident. At the same time, the problem link can be defined through data facts, so as to identify the responsible party and pursue legal and economic responsibilities; even through data analysis , which can dig out the location of the accident, the frequency of the vehicle, and the operator's frequent problems.
This cold chain temperature monitoring device is a model design for remote monitoring of cold chain temperature, the temperature monitoring device can be easily installed without complicated installation process, you do not need to replace the battery frequently, the device has a 3-5 year standby life, can Reduce errors and avoid unnecessary losses.
