Problems solved by technology

Taking a medium-sized city as an example, when more than 30,000 retail terminals are connected to the server of the tobacco company's sales management center through the GPRS / GSM wireless network, the stability and reliability of the network will become the bottleneck of the cigarette sales business. It will affect the sales data statistics of tobacco companies, and in severe cases, it will directly affect the normal operation of sales business

Embodiment Construction

[0022] A retail information terminal is provided with a main control module, the main control module includes a processor, a memory and an input and output interface, a display, a printer, a barcode scanner, a wireless communication module, a matrix keyboard, and an IP phone communicate with the main control module through the input and output interfaces connect.

[0023] Due to the large number of terminal devices, UDP / IP communication protocol and dynamic IP connection method without reliable connection are adopted. Due to the unreliable connection of UDP / IP, it may cause the loss of transmitted data, and because of the high error rate of GPRS wireless communication, unstable communication time, large delay, etc., on the basis of UDP / IP communication protocol, the finite state is added. Memory processing function and context-sensitive fault-tolerant processing technology, when the information cannot be reached or errors occur, the system can not only work normally, but also ...

Abstract

The invention discloses a retail information terminal which is provided with a main control module. The main control module comprises a processor, a storage and an input / output interface, and is connected with a display, a printer, a bar code scanner, a wireless communication module, a matrix keyboard and an IP telephone through the input / output interface; a UDP / IP communication protocol without a reliable connection and a dynamic IP connection mode are adopted; based on the UDP / IP communication protocol, a finite state memory processing technology and a context-sensitive error-tolerance processing technology are added; when the formation fails to reach or has a mistake, the system can not only normally work, but also correctly perform data statistics. The invention takes advantage of a mobile communication GPRS wireless communication public platform, is based on an embedded real-time operating system and an embedded database, adopts embedded integrated design concept, has the functions such as automatic information report, sales information classified management, software auto-update and so on, realizes the real-time error-free transmission of the information, and assures the timely and accurate report of the retail information.

Description

technical field [0001] The invention relates to an information management system in the sales field, in particular to a retail information terminal using GPRS / GSM wireless communication as a transmission platform. Background technique [0002] With the rapid development of GPRS / GSM technology, the application of GPRS / GSM wireless communication platform is becoming more and more mature, and it is widely used in remote data collection such as mobile commerce, remote monitoring and other fields. In the retail industry represented by cigarette retail, due to the characteristics of large number of retail outlets, wide area, and miscellaneous scale, GPRS / GSM wireless network has the characteristics of wide coverage, convenient installation, and low usage fee. Therefore, GPRS / GSM is widely used. The GSM wireless communication platform is used as an interconnection medium for data exchange. [0003] Compared with the wired network, the communication quality and bandwidth of the GPR...
