As one of the most important devices in cold chain logistics, cold chain trucks ensure that frozen foods maintain a stable low-temperature environment during transportation, so that foods are not affected by rising environmental temperatures during production, storage, transportation, and sales. Ensure food quality and reduce food loss.
For cold chain vehicles, if the refrigerated part changes due to temperature, it is difficult for the driver to detect it in the cockpit. Once the temperature changes, it may cause all the food in the car to be damaged. Therefore, how to monitor the temperature of the cold chain car has become an important matter.
The cold chain vehicle monitoring solution is based on the Internet of Things technology, which integrates GPS technology, wireless transmission technology, temperature detection technology, electronic map technology, etc., which can monitor the operating status of the cold chain vehicle throughout, all day, and wirelessly. Ensure the safety and stability of the cold chain operation of the cold chain truck.
System composition
The cold chain vehicle monitoring program consists of three parts: the front-end monitoring part, the wireless transmission part, and the cold chain management center.
Front-end monitoring part: The front-end monitoring part is composed of temperature monitoring module, GPS positioning module, fuel consumption monitoring module, door status monitoring module, video monitoring module, buzzer and other modules, which respectively monitor the temperature, location, abnormal fuel consumption, door, The food dynamics and other data in the car are monitored in real time. Once an abnormality occurs, the driver will be reminded to deal with the abnormality through the buzzer, and the abnormal data will be sent to the remote management center to facilitate the synchronization of the data.
Wireless transmission part: The wireless transmission is mainly based on the computer's industrial-grade router TR341, through the front-end temperature monitoring module, fuel consumption monitoring module, door status monitoring module, camera and other equipment connected to the computer's industrial-grade router, through major operators Provide 5G/4G/3G wireless network to transmit data to remote cold chain management center;
Cold chain management center: The cold chain management center receives and processes data from cold chain vehicles, and at the same time observes and judges the data through the large screen, mobile phone, and PC, and alarms for abnormalities.
System functions
1. It can monitor the temperature in the cold chain car in real time, and once the temperature is too high or too low, it will alarm in time to reduce the probability of food damage;
2. The cold chain vehicle running track can be drawn on the map to determine whether there is a long-term stay and drive away from the normal route;
3. Carry out real-time monitoring of the fuel tank, determine whether there is a leak or delay in refueling, and remind the driver to deal with it in time;
4. Observe whether the door of the cold chain car is closed tightly to prevent the cold air from flowing out and causing food damage;
5. Real-time monitoring of images in the cold chain car, problems can be tracked in time to determine the source of the problem.
The cold chain vehicle monitoring solution can ensure that the entire data of the cold chain vehicle is tracked, avoiding food damage caused by abnormal equipment during operation, and ensuring food safety. The source of the missing items can also be found in time.
