Abstract

PURPOSE:To grasp the connection status of POS terminals and to make a titled system deal with the generation of troubles by outputting a polling command from a processing device in every prescribed period, collecting polling data and reading out data in a control table provided in a memory to the other memory to compare the data with prescribed data. CONSTITUTION:POS terminals 1 are connected to a terminal controlling device 3 provided with a control part 4 connected to the 1st memory 5 respectively through addresses A1-An and a control part 2 is connected to the device 3. The 2nd memory 12 and a display part 15 are connected to a processing unit 7. The device 3 provided with a polling table 6 receives a polling command P from the unit 7 in every prescribed period, stores information relating to response/no response from each terminal 1 in the table 6 and transmits the information to an area 11 in the memory 12. A discrimination part 9 in the unit 7 compares and discriminates the polling data in the area 11 with/from the prescribed data in a table 13 to grasp the connection status of respective terminals 1 and quickly deal with the generation of troubles.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a terminal connection status management system for grasping the connection status of PO8 terminals.

The point-of-sale information management system has a configuration in which a plurality of POS terminals are connected to a control device, and this control device/device is connected to a processing device at a center.

In such a system, each PP0S is
When polling the terminal.

In the conventional method, processing is started with a POS terminal that has responded, and on the other hand, the status of a POS terminal that has not responded is not managed. The cause of the non-response may be a disconnection of the connection line or a disconnection of the device's power supply, but when such an abnormality occurs, the operator of the POS terminal should report the situation to the system administrator at the center. When I didn't.

Although there is a drawback that countermeasures against failure on the center side are delayed, the present invention has been made to solve the above drawback.
The purpose of this invention is to provide a terminal connection status management method that can easily grasp the connection status of terminals.

The present invention achieves this object in a system in which a terminal device, a terminal control device having a first memory, and a processing device having a second memory are connected.

a management table provided in the memory of said side 1;

Further, the terminal control device is provided with means for storing information related to a response/non-response from the terminal device to a polling command in the management table.

A means for comparing and determining the data in the management table and predetermined data is provided, the polling data is collected by issuing a polling command from the processing device at predetermined time intervals, and the data in the management table is stored in the second memory. The connection status of the terminal device is determined by extracting the information and comparing it with predetermined data.

The present invention will be explained below with reference to the drawings. The drawing is a block diagram illustrating an embodiment of the present invention.

lTrl is time data. Memory 12 in the drawing
Table 13 includes addresses A1 to A1 of each PO8 terminal 1.
An and data related to each PO8 terminal are stored. In the drawing, when a polling command P is issued from the processing device 7, a response is obtained from each PO8 terminal. For example, if there is a response from the PO8 terminal 1 of the address AI, the control unit 4r of the terminal control device @3! .

Write the signal “]” as the ll-specific code (Sl) to the address A1 item of the polling table 6 of the memory 5.
Write "0 minute" as time data (Tl). On the other hand, if there is no response from the PO8 terminal 1 at address A2, the control unit 4 writes the signal rOJ as the R-specific code (82) to the address A20 item of the polling table 6, and writes " Write "0 minutes". By issuing the polling command P in this way, each PO8
Information indicating the connection state of the terminal 1 is recorded in the polling table 6. Next, after a predetermined period of time (for example, 0.6 seconds),
When polling command P is issued again, if there is no response from PO8 terminal 1 at address A2.

The control unit 4 writes "o, s seconds" as the time data T2 in the address Ax item of the polling table 6.

The reason for the non-response is that the POS terminal 1 is powered off, or one line is disconnected. Therefore, as described above, if the polling command P is issued every 0.6 seconds, the polling table 6 will also record the elapsed time from when no response occurs.

In response to a read command (indicated by - in the figure) from the application program 14 in the memory 12, the boring data fi of the polling table 6 in the memory 5 is transferred to the area 11 in the memory 12. Determining unit 9 By comparing and determining the polling data in the Fi area 11 and the data in the table 13 (addresses A1 to An and other data) for each address, it determines which PO8 terminal is not responding, System @81.0 is.

The results are displayed on the display section 15. This display data allows the operator to know the existence of the unresponsive PO8 terminal and the elapsed time since the occurrence of the abnormality. By constantly displaying the data '1 of the polling table 6 on the display section 2, each P
This allows the status of the O8 terminal to be grasped.

As described above, the present invention makes it possible to grasp the connection status of PO8 terminals at the application program (user) level in the processing device of the center, and has the advantage of being able to quickly respond to irregularities that occur. have
