Container GPS satellite positioning monitoring solution
1. Application background of smart container solutions
With the development of trade globalization, the development of the logistics industry is also closely following the pace of trade, and logistics companies have higher and higher requirements for safety and timeliness in the logistics process. Containers change the world. The importance of containers to the logistics industry is self-evident. Whether it is domestic or cross-border logistics, customers hope to know the location and status of goods in a timely manner through mobile phones or computers. Therefore, more and more container owners and Logistics companies deploy smart container solutions.
2. Intelligent container solution
2.1 System overview
The "smart container solution" developed by iLinkCon technology integrates GPS, Beidou positioning system, 4G/3G/2G/Nb-IOT communication system, environmental monitoring system, empty and heavy load detection system, door switch detection system and humidity detection system, etc. Technology, as well as background data processing systems such as GIS geographic information processing system, background data management system and client remote monitoring system, realize the intelligence and visualization of smart containers throughout the transportation process.
2.1.1 Overall plan
The smart container solution is composed of three parts: the GPS positioning tracker installed outside the container, the container monitoring sensor installed inside the container, and the container status monitoring platform deployed in the cloud. The terminal equipment collects various status data of the container, and regularly sends the status data to the container monitoring and management platform. The platform can also remotely operate and upgrade the equipment online.
2.1.2 System Composition
(1) GPS positioning tracker: the key and core part of the system terminal equipment, which integrates GPS, Beidou, 4G/3G/2G/NB-IOT data communication system, and the software includes data acquisition and communication parts.
(2) Sensors in the box: temperature detection sensors in the box, empty and heavy load detection sensors, humidity sensors, door switch detection, etc.
(3) Container monitoring and management platform
The system is characterized by a browser/server-based structural design, which can be monitored and controlled anytime and anywhere without installing a client.
Mobile network: Provide a dedicated communication link between the GPS location tracker and the network
SMS gateway: The GPS location tracker can communicate with the communication center through SMS. The communication center can also automatically send information to the manager's mobile phone according to the container warning situation.
Monitoring server: Receive GPS location tracker information, analyze the data according to the communication protocol, and write it into the database. It can also receive control commands from the web client and forward them to the container terminal equipment.
Database: store all data generated by the management system.
2.1.3 System functions
1. Temperature, empty and heavy load, door switch detection, motion monitoring
(1) Temperature detection: monitor the ambient temperature and the internal temperature of the container through the temperature detection module
(2) Empty and heavy load detection: Through the empty and heavy load detection sensor, it can detect whether the inside of the box is loaded with media.
(3) Door switch detection: By installing a door switch detection sensor inside the box door, the switch state of the box door is detected.
(4) Motion detection: Through the built-in acceleration sensor, monitor whether the container is in a moving state or a static state.
2. Battery power detection and low voltage alarm
The container GPS positioning tracker can regularly detect the battery power and battery voltage. When the battery voltage is lower than the threshold, the container GPS positioning tracker will remind the device that the battery needs to be replaced.
3. GPS positioning and remote data transmission
The system can regularly upload the location information of the container to the background system through the GPS/BDS positioning system and the A-GPS system with the help of the data transmission means of the mobile network, so as to realize the location of the container.
The positioning accuracy of GPS/BDS is less than 15 meters. When the GPS of the container cannot be located, the positioning data of the base station will be uploaded, and the position will be deviated.
The regular upload frequency of mobile network data can be set remotely through the monitoring and management platform, but the regular upload frequency of mobile network directly affects the service life of the battery.
4. Map application function
Map zoom in, zoom out, roaming Zoom in, zoom out, historical track playback and other functions.
