As shown in Figure 4, system software is made up of bsp driver, operating system, middleware.Embedded real-time operating system has safe and reliable, and application and development is convenient, and is convenient to operation, can handle multimedia messages, possesses powerful advantages such as network support.Adopt embedded real-time operating system and can shorten the construction cycle greatly based on the MicroWindows graphical development tool of this operating system.Bottom layer driving software is driven by keyboard drive, GPRS driving, USB driving, printer driver, display driver, serial port and power management routines is formed, and finishes the device hardware signaling interface.Middleware software is made up of embedded database, GPRS protocol stack, finishes the Data Format Transform of transmission, reception information.
As shown in Figure 5, the retail information terminal application software mainly is made up of input and output event processing module (main control module), input processing module, data processing module, display module, remote communication module etc.Application software is a main control module with the incoming event processing module, calls other modules according to the information that reads and specifically handles.
As shown in Figure 6, communication fault-tolerant processing technology of the present utility model adopts finite state memory and context correlation processing technique, realizes the fault-tolerant processing of message.The data that router will need to send deposit the transmission buffer zone in and start the transmission of GPRS/GSM module, when the transmission message obtains replying, this message of deletion in buffer zone, to the message that do not obtain receiving successful respond in fixed interval after the time (set time can be provided with as required) or receive the follow-up supervention of request message and send, till receiving the other side's response message.Even the UDP message is lost in process of transmitting or is made mistakes or delay time like this, but data finally can be successfully, correctly transmit, played fault-tolerant effect.Retail information terminal adopts the processing procedure of finite state memory technique to be: and application regular length M during the information terminal start (the transmission buffer zone of I * C), router reads in buffer zone with data and sends from send message file (storage need send data); After being sent completely, wait for replying of sales management central server; If then cleaning sends buffer zone and sends message file according to the response message numbering to receive response message; After waiting for preheating setting time T (the big I of T is provided with as required),, then finish to send if it is empty to send buffer zone; If buffer zone is not empty, then carries out the next round message and send, till all messages send successfully.
For correctness and the reliability that guarantees system works, information terminal adopts context dependent fault-tolerant processing technology when reporting marketing information, utilizes the context dependence of inventory information to add up marketing information.Suppose that retail information terminal first stock constantly is the stock
1, the stock in second moment is the stock
2, be carved into the second interior during this period of time constantly marketing information for selling from first o'clock
1, the rest may be inferred, and i stock constantly is the stock
i, be carved into i sales volume constantly during i-1 for selling i
-1So:
By formula as can be seen, stock
3Equal the stock
2Deduct sale
2, inventory information is always relevant with last inventory information next time, and therefore there is correlativity in twice inventory information up and down.
In the utility model, retail terminal adopts and reports stock's mode to add up marketing information, retail terminal T1 (T1 can be provided with as required) at set intervals reports the stock one time, the sales management center receive behind the stock with database in the stock subtract each other the data that obtain and be marketing information, upgrade inventory database with the stock who reports then.Because the correlativity of inventory information, though the inventory information that reports in transmission course, lose or delay time or make mistakes, but still correct to the statistics of marketing information.Suppose through transmission back stock
1, the stock
3Correctly, if the stock
2Become the stock '
2(suppose the stock '
2=stock
2+ V), so:
Draw:
Sell '
1+ sell '
2=sell
1+ sell
2
