the starting unit 1061 is configured to start and invoke the GPRS wireless communication module through an AT instruction, where the AT instruction is sent by the data terminal device DTE.
The AT is an Attention, and the AT instruction set is sent from a Terminal Equipment (TE) or a Data Terminal Equipment (DTE) to a Terminal Adapter (TA) or a data circuit terminal equipment (DCE), and the AT instruction is sent by the TA or the TE to control a function of a Mobile Station (MS), interact with a global system for mobile communications (GSM) network service, and a user can control a call, a short message, a phonebook, a data service, a fax, and the like through the AT instruction.
The generating unit 1062 is configured to establish a TCP/IP network connection, encapsulate the final information to generate a target data packet, and send the target data packet to the monitoring module.
A transmission control protocol/internet protocol (TCP/IP) specifies a standard and a method for communication in the internet, and is an important protocol for ensuring timely and complete transmission of network data information, and the generating unit 1062 encapsulates data based on the TCP/IP, generates a data packet, and sends the data packet to the monitoring module.
And the monitoring module 107 is configured to analyze the target data packet to generate analysis data, and store the analysis data in a preset SQL Server database according to preset categories, where the preset categories include vehicle history tracks and cargo history data.
The SQL Server database is a relational database management system, which is used for large-scale online transaction processing, data warehouse and electronic commerce application, and can also be used for data integration, analysis and report solution, the SQL Server architecture comprises 4 main components: a protocol layer, a relationship engine, a storage engine, and an application layer. The monitoring module completes information display based on a Qt tool, calls a preset API interface function and multithreading QThread processing data, displays an electronic map by using a QtWebkit component under the Qt tool, calls a preset SetUrl function to create a system main interface and display a main window of a program, and the Qt has the characteristics of multithreading, cross-platform, portability and the like, supports all important data driving, can seamlessly connect a database and a Qt application program, and is wide in application field.
The embodiment of the utility model provides an in, based on vehicle mounted terminal and remote monitoring center, realized the dynamic management of cold chain logistics transportation, improved cold chain logistics industry quality of service and operation service level, reduced the loss in transit of agricultural product.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
