[Detailed description of the invention]

[Summary] An ID number registration sequence that stores an end-unrecognized code added from the value-added communication network in the master POS terminal's internal memory, and adds this end-unrecognized code to the front of the call signal when starting transmission. and reception ID analysis means for checking whether an end unrecognized code is added before the response signal and whether the end unrecognized code is a regular one. [Industrial Application Field] The present invention relates to a transmission control system for a POS terminal using a value-added communication network. [Prior Art] FIG. 4 is a diagram showing an example of a communication method of a conventional POS terminal. In the diagram, 1 is the host computer, 2 is the master
POS terminals, 3 ₁ to 3 _o are slave POS terminals, 4 is a public line, and 5 is a slave line. Traditionally, specialty stores, etc., which are based on small-scale multi-store management, have installed one host computer at the head office location.
, a master POS terminal 2 is installed at each branch in each region, and a public line 4 is connected between them.
The POS terminal 2 is connected to a plurality of slave POS terminals 3 ₁ to 3 _o via a slave line 5. Transaction data that occurs during business hours at various branches is temporarily stored in the memory of the slave POS terminals ₃₁ to _3o , and the sales data is mastered after the branch is closed.
The data is transmitted via the POS terminal 2 to the host computer 1 at the head office location using the public line 4. FIG. 5a is a hardware configuration diagram of a conventional master POS terminal 2. As shown in FIG. FIG. 5b is a software configuration diagram of the master POS terminal 2. In the figure, 10 is a processor, 11 is a keyboard,

The conventional master POS terminal 2 has a hardware configuration as shown in FIG. 5a and a software configuration as shown in FIG. 5b. That is, the transmission control means 2 operates under the control of the task controller 20.
2. Tasks such as a reception control means 23 and a message editing means 25 are provided, and each of these means operates in sequence to exchange data between the host computer 1 and the master POS terminal 2 via the public line 4. conduct. [Problem to be solved by the invention] However, with this method, if there are many stores in remote areas, the charges for using public lines will be enormous, which will outweigh the benefits of improving the efficiency of office processing by introducing POS terminals. However, the disadvantages of high operating expenses were more noticeable, and the problem was that only large, financially stable specialty store chains could see the benefits of introducing them. Recently, large-scale value-added communication networks (hereinafter referred to as VANs) have expanded to include the Tokyo metropolitan area, Chukyo area, Kansai area,
Local cities now have bases (access points) for network connections, and POS terminals can connect to your own host computer by simply calling the access point instead of calling your own host computer in a remote location over a public line. communication has become possible. When using a large-scale VAN service network like this, communication charges are cheaper than conventional methods that use only public lines, so if there are many stores in remote areas, the disparity in communication charges will increase. For this reason, expectations are high for economical online services that utilize VAN services provided by the recent telecommunications liberalization. The purpose of the present invention is to add simple software to the conventional system so that it can be used not only for conventional public lines but also for VAN.
The purpose is to provide a transmission control method for a master POS terminal that can use services. [Means for solving the problem] As shown in _{the principle} diagram of FIG. ID number registration sequence means 21 for registering the end unrecognized code added in the value-added communication network 6 in the internal memory of the master POS terminal 2, which is sent to the host computer via the ID number registration sequence means 21; When starting, check whether an end unrecognized code is registered in the internal memory,
If it is registered, the terminal recognition code is added to the calling signal and sent to the added value communication network 6, and if it is not registered, the ID transmission control means 22a sends the calling signal to the public line, and the response signal is This problem is solved by a transmission control system for a POS terminal characterized by comprising a reception ID analysis means 24 that determines whether an unrecognized code is added and performs reception processing based on the result. [Operation] According to the present invention, by operating the ID number registration sequence means 21 in advance in the master POS terminal 2, the end unrecognized code given from the value-added communication network 6 is transferred to the master POS terminal 2.
It is stored in the internal memory of the device, and when transmission starts,
The ID transmission control means 22a checks whether the end unrecognized code is stored in the internal memory, and if it is registered, adds the end unrecognized code to the calling signal and sends it to the value-added communication network 6; If it is not registered, the calling signal is sent to the public line, the reception ID analysis means 24 determines whether or not the end unrecognized code is added to the response signal, and the reception processing is performed based on the result. I have to. Therefore, it is possible to use the VAN as long as the end-unrecognized code is registered, and to use the public line only when it is not registered, thereby saving costs. [Embodiment] The present invention provides a transmission control method that allows a conventional master POS terminal 2 connected to a host computer 1 via a public line 4 to be connected to a VAN. FIG. 2 is a diagram showing an embodiment of the present invention. Figure 3a shows the processing flow of the ID registration sequence.
FIG. 3b shows the transmission procedure flow. In the figure, 6 is a VAN, 21 is an ID number registration sequence means, 22a is an ID transmission control means, and 24 is a reception
It is a means of ID analysis. These are programs provided in the form of tasks in the internal memory 15, and the processor 10 executes the tasks to execute the corresponding functions. In order to connect the conventional system to VAN 6, ID number registration sequence means 21 and ID transmission control means 2 are added to the software configuration of master POS terminal 2.
2a, and a tank, which is the reception ID analysis means 24, are added. (1) ID number registration sequence means 21 When the master POS terminal 2 joins the VAN, it is given an unrecognized code (referred to as an ID number) by the VAN. This ID number is registered in the master POS terminal 2 according to the ID number registration sequence means 21. In this case, the ID number given by VAN is 8.
Suppose it is a digit number XXXXXXXXX. The ID number registration sequence 21 can be arbitrarily defined by the system, but for example, as shown in FIG. In other words, first enter 05, then enter the 8-digit number from the numeric keypad.
Enter XXXXXXXX and finally press the "Deposit/Total" key. When 05 is input, the ID number registration sequence means 21 operates, and when the "Deposit/Total" key is pressed, the input 8-digit number XXXXXXXX is registered as the ID number of the master POS terminal 2.
Terminal 2 internal memory 15 (DRAM or
Store and register in the specified area of CMOS). (2) Transmission procedure flow When master POS terminal 2 transmits, it performs the transmission operation according to the following procedure. ID transmission control means 2 which is a program task
Run 2a and check whether the IKD number is already registered. If not registered, send buffer 1
After that, the conventional transmission control means 22 operates to send a calling signal to the host computer 1 using the communication line 4. If the ID number is registered, the ID number is read from the internal memory 15, an ENQ character with the ID number is set in the transmission buffer 17, and the transmission control means 22 then operates to transmit data to the VAN using the communication line 4. Send a calling signal. In response to the sending of the above signal, a response signal is sent from the host computer 1 or the VAN. The received ID analysis means 24 operates and checks whether an IKD number is registered in the sent signal. If it is not registered, it is a response from the host computer 1, so the conventional reception control means 23 performs the reception process. If you are registered, your ID number will be your own.
Check whether it is an ID number. If it is not your own ID number, perform line disconnection processing. If it is the own ID number, the reception control means 23 performs reception processing. When the receiving process is completed, the process moves to a message sending process in which the messages created by the message editing means 25 are sequentially sent out in the same way as in the conventional system. [Effects of the Invention] As explained in detail above, according to the present invention, it is possible not only to perform conventional transmission using a public line but also to transmit to a VAN by adding very simple processing. effective.
