Technical Field
Modern logistics GPRS module is one of the foundations of the national economy and has been recognized as the third important source for companies to create profits.
In addition to reducing material consumption and increasing labor productivity. However, the current operational level of logistics and transportation is generally not high, which has brought great inconvenience to the development of industrial and commercial manufacturing enterprises. Events such as out-of-stock products, lost orders, and stolen goods often occur.
Logistics tracking technology as an implementation of logistics value-added services and an important means of visualizing logistics processes.
In terms of transporting goods and tracking vehicles, tracking technology began to be applied to multimodal transport to achieve full tracking of multimodal transport.
Logistics tracking technology is further extended to warehousing and production logistics, and bar code-based warehousing identification and cargo identification applications in production logistics have been further developed.
At the same time, RF-based logistics tracking technology began to demonstrate applications in the pharmaceutical, retail and other industries. Secondly, the application of logistics tracking technology has begun to penetrate into the logistics and supply chain, including warehousing, transportation, distribution and production logistics, showing the trend of tracking and visualization for the whole process.
Background Technique
1. A variety of tracking technology integration.GPRS module
Logistics tracking technology from the traditional GPS / GIS as the main technology, to GPS, GIS, GPS, Bluetooth technology, bar code technology, RF technology and other tracking related technology integration, while tracking technology and transportation management system, warehouse management system, distribution management information systems such as management systems and enterprise management information systems show further integration.
2. Tracking heterogeneous sharing of data.
Tracking data comes from multiple business links and multiple information systems. The format and content of the data are relatively heterogeneous. Currently, XL technology is mainly used to share heterogeneous data. ML technology converts heterogeneous data into a structured data format for information sharing.
3. Chain query of tracking data.
The chain query realizes the data level connection query between multiple databases in the whole process of the logistics process. The implementation methods are the same system non-heterogeneous chain query and different system cross-platform chain query. The application of logistics tracking technology will be further applied in the procurement, transportation and warehousing of the supply chain. At the same time, the logistics tracking technology represented by RF technology will be applied in the pharmaceutical, automotive, retail and other industries.
Technical Solutions
The processor uses OSD3358-512M-BAS, which is the platform for the MPU and software running of the logistics tracking system battery. The OSD3358-512M-BAS standard RISC embedded microprocessor operates at 1 GHz. Built-in 32 kB, 32 kB, 256 kB FLASH memory and 64 kB SRAM, memory supports CF card, SRAM, PSRAM, NOR and NAND memory, embedded serial single-wire JTAG debug interface, embedded tracking module (ETM), Provides clear instruction operation and data flow information when the chip is running. It has three low-power modes: sleep, stop, and standby mode. U-Blox’s SARA-R410M-02B high-performance GPRS chip, an RFID reader, and TI’s WL1835MODGBMOCT WiFi module are installed in the information collection terminal.
IoT circuit board Assembly Specification GPRS module:
75 different components are used in this PCBA board, including a main control chip, diodes, triodes, crystals, inductors, resistors, capacitors, and others. The board has six layers and does not have any blind buried holes.
Bluetooth Module
The Bluetooth module and the wifi module mainly function as a signal transmission box on the circuit board, which can perform tracking and positioning of the bound goods, and convert the serial port or TTL level into a Wi-Fi wireless network communication standard. Embedded module, built-in wireless network protocol IEEE802.11b.gn protocol stack and TCP/IP protocol stack. Of course, wifi has many application areas, such as WiFi monitoring, WiFi Internet radio, camera and so on.
WIFI Module
The main components of the IoT vehicle tracking circuit board are the GPRS receiving module and the server.
The GPRS module uploads the received logistics information to the server storage chip.
The control chip will call the signal in the storage chip for judgment and identification.
If the signal and the client request are consistent. The board will continue to track and monitor. If the signal does not match the client, the server will make a corresponding alarm indication after data analysis.
For the loss of valuable items and the inability to collect real-time logistics information in the current logistics process.
The system can monitor the valuables in real time during the logistics process. Once an abnormal situation occurs, the logistics personnel can be notified in time to reduce the loss of valuables.
The logistics supervision platform uploads logistics information to the platform in real-time and further enables information communication with the customers in the following research.
So that the client can understand and supervise the logistics process of their own items in real time, which is safer and more efficient in the logistics industry.
