Intelligent refrigerated truck vehicle-mounted data acquisition terminal system based on Internet of Things technology

Abstract

The invention relates to the technical field of refrigerated trucks, and in particular relates to an intelligent refrigerated truck vehicle-mounted data acquisition terminal system based on the Internet of Things technology. The vehicle-mounted data acquisition terminal comprises expandable 12 paths of temperature and humidity sensors, one path of image sensor which is used for acquiring picture information in a carriage in real time, two Hall sensors which are used for detecting opening and closing information of the carriage door in real time, a GPS satellite positioning system which is usedfor positioning the position of the vehicle in the driving process in real time, an MPU6050 sensor which collects the acceleration of vehicle driving and the vehicle body angle information in the carriage driving process in real time, and a two-way relay control system which controls the refrigerating machine system and can print out data information in the running process of the refrigerated truck and store the data information in a USB flash disk; the 4G module enables the acquisition terminal to be connected into the Internet of Things cloud platform through an Internet of Things protocol,and data display, big data analysis and intelligent decision making are achieved on the cloud platform. According to the system, transparent management of cold-chain logistics is realized, and intelligent regulation and control of the temperature of the refrigerated truck are realized.

Description

technical field [0001] The invention belongs to the technical field of refrigerated vehicles, and in particular relates to an intelligent refrigerated vehicle vehicle-mounted data acquisition terminal system based on Internet of Things technology. Background technique [0002] With the improvement of people's living standards and the continuous development of society, the logistics industry has gradually become an indispensable industry to ensure people's normal life. As the main means of transportation for cold chain logistics, refrigerated trucks play a huge role in the entire cold chain. The performance of refrigerated trucks and the performance of the refrigeration system will directly affect the quality of refrigerated goods. Therefore, the status detection of refrigerated trucks during transportation and the control of refrigerated systems are particularly important. The status detection and control of refrigerated trucks can effectively solve the problem of blind spo...

AI Technical Summary

Problems solved by technology

However, the traditional refrigerated car monitoring system has many defects, the control is simple, and the actual state inside the car cannot be monitored in real time. It can only detect the temperature of a certain part inside the car to control the refrigeration system. The control strategy is not scientific and representative. In the case of uneven distribution of the temperature field inside the car, the strategy of feedback control cooling system is unreliable. Energy consumption is used, and it is easy to cause the temperature rise of items in areas where some cold air is not easy to reach and deteriorate

And when the temperature points inside the car are arranged, the traditional method is to arrange them in the cold machine part inside the car, and the number of sensors is not particular.

In addition, during the transportation process, transparent management cannot be realized, and the real-time status inside the refrigerated truck and the compartment cannot be provided to the transportation personnel, merchants, and customers. Problems cannot be solved in a timely manner and responsibilities cannot be clarified.
