Abstract

PURPOSE:To ensure the smooth restoration of the faulty system control for a data processing system, by switching a switch only if a fault arises to the control of a file controller that controls a cash register. CONSTITUTION:File controllers 6 and 8 having main/sub changeover switches 5 and 7, and a data file are provided in a circuit of a system. A changeover switch 5 is set at the main side for the controller 6 to control cash registers 1 and 2. Then the register data are fetched from the registers 1 and 2 and stored in own data files. At the same time, a changeover switch 7 is set at the subside for the controller 8. Thus the controller 8 copies the contents of the data file of the controller 6 to its own data file.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] This generation II#B multiple electronic carriages and registers are serially connected to each other by a file controller having a data file in the mouth to output data sounds from each carriage and register. A data processing method in a product fraud processing system that stores data in a data file is provided.

[Technical background of the invention and electric point between them]

The conventional system for selling music products of this stock
＆, 1l111絵第中#c 1 file controller is used to control multiple electronic cash registers and the data from each cash register is stored in a data file. Therefore, if a connection failure between the file controller and the line or a circuit failure occurs in the file controller, the file controller becomes unable to control the cache and registers, causing the entire system to become erratic.

[Purpose of the invention]

This invention has been made to eliminate the above-mentioned drawbacks.
This product provides a data processing method in a sales system that can easily restore system J711+U Ht data processing with a simple operation.

[Value of the invention] ””” ””□This invention interposes multiple file controllers with data files and main/sub changeover switches in the system line, and one of the valley file controllers is installed in the main switch +1 to control each cap, switch, and reno star.
control, each carriage, imports 1 registered data from the register and stores it in its own data file, and leaves at least one of the remaining file controllers (0-1) without a changeover switch. Copy the contents of the data file of the main installation file control 0=un to its own data file by setting it up, and when the main file controller fails, switch the sub installation file controller with the switch.

A change flag CF, an aggregation work area AWA, and a file area FA as a data file are formed as the main memory.

The central processing unit 34 controls each Wj
When the main setting signal is input from the contact judgment foot circuit 44, it controls the storage of the data from the carriage island register 1 or 2 in the file area FAK, and when the sub-power setting signal is input. File area FAK of the installed file controller
Controls copying and storing of stored data in its own file area FA. In other words, as shown in the flow 21 in FIG.・Check the access memory 40, etc., that is, perform initial l6nt. If the input from the contact judgment foot circuit 44 is the main setting signal, the memory 40 work・
Clear areas OVA and AWA. After that episode 1
If there is data input from iIJ or 4 to the driver/receiver circuit 4JK, the data goes to the data.If the code is 09, it is determined that the data is input from the register, and the data The message is stored in the change buffer CBtfC, and the change flag CFvt
to When the header code is 09, the address occupies 3 bytes of the message.
A, G] number, l (data occupying i bytes P
It is determined that it is LU data, and the PLU data is stored by specifying the address using the PLU storage unit KPLU in the file area F. Also, when the header code is 11, it is judged as a request to send data from the file controller of the sub settings. 6th change flag CFt is checked, and if the flag CF is set, the data of change pa, fa CB is sent. is prepared as sending data, and the data is appended with ``da=13'' and sent from the driver/receiver circuit 43 to the file controller of the sub setting.

If the critical change flag CF is not set, 1 from the address visited by the address data in the message.
28-byte data is prepared as tfs output data, an address and a header 13 are attached to the data, and the data is sent to the sub-setting file controller.

If the input from the contact determination circuit 44 is a smooth setting signal, the work area OWA of the memory 40 is reached.

After that! 14 or 3 to driver/receiver circuit 4
It is determined that the data input to 1 is from the main setting file controller, and first it is determined whether the end of that data is 12 or 13. If the header is 12, the address is designated by the address in the data and stored in the 1g8-byte r-t file area Fm.

Then 128 pies to the current address)! Add that fr
If the new address is not the end address, use that address to send the next data to the main file controller, and if the new address is the end address (1 - 1), the address is Set the star address address again to Aream DR, and use that address as the address to be leaked to the next data transmission and file controller of the meeting main setting. Also, lesson 1.
.

If the number is 13, read the PLU number from the input data and store it in the PLU storage area of the 7 fill area Fm according to the LU number.

In addition, the central processing unit J4 turns on the light emitting diode when a connection failure occurs in circuits 1ii3 or 4 to the driver/receiver circuit 43, or when a failure occurs in each circuit 8.

The alarm circuit 31 is operated to notify the user.

Each changeover switch 27/, 28°2#t is set to the main contact M, and the valley changeover switch in the second file controller 8 switch character 115e is set to 21.28.
29 to the t contact S. By doing this, the first file controller 6 can transfer both electronic carriers from the Schrezoster 1.2 to the times Ii! 114 and 3, which are transmitted in a link manner, are sequentially fetched and stored in the file area F. - The file controller 8 of the blade group 2 sends the attached message to the first file controller 6 via the lines 4 and 3, and stores the file area FAK of the file controller 6 of that line. Normal data is 128 bytes each in 5i! :(I
NL and PLU data is received in 16-byte units and FAK-copied to its own file area. During such operations, if a problem occurs in the first 7-aisle controller 6 such as a defective line iI cable or an internal circuit failure, the light emitting diode lighting circuit SC operates and the light emitting diode lights up. And the alarm circuit J1 operates and an alarm sounds.

This allows the operator to immediately control the file control page of Collection 1.

Therefore, energization to each relay coil 41.46.4''l of the connector 5 of the silver file controller 6@ is stopped, and the input section to the HBso first 7-aisle controller 6 is short-circuited.- - Since the file controller 8 of the blade part 2 is set to the main setting, 9ik are both carriages, register 1.
2 is received and stored in the file area FA. In this case, all the data received by the first file controller 6 has already been copied and filed in the file area FA of the file controller 1 of the 18g2, so the file controller 6 of the IIEl will not malfunction. The 7-aisle area F A tllflr can be executed in exactly the same state as that in which data is continuously being received from the cash register 1.2.

In this way, even if the first file controller 6 goes down, the switch mechanism 300☆switch switch in the second file controller 6. □xs, zy
With a simple operation using only a pipe switching stone, one damage can be done without interfering with system control data processing.

In addition, in the 111I recording embodiment, the case was described in which two carriages and registers were connected, but any number of carriages and registers may be used as long as they are plural.

In the above embodiment, two file controllers are connected, but this is not always necessary; in this case, one should be connected as the main power source, at least one of the remaining ones should be connected with TTF, and the others should be set to off. By doing so, even if multiple p-file controllers go down, it can be handled satisfactorily.

〔Effect of the invention〕

As described above, according to the present invention, even if the file controller that controls the cache, register, and the like becomes uncontrollable, the system can be controlled by simply switching a switch.
- It is possible to provide a data processing method in a product processing system that has a high purchasing effect in one go without any problems in data processing.
