Abstract

PURPOSE:To easily set the time of each terminal equipment by securing such constitution where a controller transmits a time setting telegram to the corresponding terminal equipment and this equipment set the time after a certain terminal equipment transmitted the time setting request telegram to another terminal equipment. CONSTITUTION:A terminal equipment 2 accepts the input of the time data in a time setting mode and transmits this time data to a controller 1 after editing it into a telegram. The controller 1 receives the time setting request telegram from the equipment 2 and edits again this telegram into another telegram to be addressed to each equipment 2 written in a set range to transmits this telegram to each equipment. Each equipment 2 receives the time setting telegram from the controller 1 and reads the time data out of the telegram if the time data is addressed to its own station to update the data on a timepiece circuit. Thus the time points of all equipments 2 can be easily matched with each other.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION OF FAT This invention relates to a time setting method for a system comprising a plurality of terminal devices and a control device.

(bl Conventional Technology) In a system in which multiple terminal devices are connected via a control device, each terminal device operates based on a specific time (for example, an automatic transaction processing device operates at a specific time). (for example, when the operation ends or a fee is charged after a certain time), one method is to have each terminal device have a timekeeping function to judge the time, and the other is to have the control device have a timekeeping function and to judge the time. There is a method that determines the time by communicating with the control device when it is necessary.

(C) Problems to be solved by the invention However, in the former method, the time must be set for each terminal device, which requires a great deal of effort, and it is difficult to maintain consistency in time between terminal devices. However, when changing the data processing method or service handled as described above based on a specific time, variations occur between each terminal device, making it difficult to make all terminal devices operate in the same way.

In addition, in the latter method, the terminal device must communicate with the control device in order to judge the time, and this communication has the disadvantage that the communication ability and data processing ability of the terminal device and control device are reduced. was there.

In view of the current situation, it is an object of the present invention to provide a time setting method that makes it possible to set the same time on each terminal device through a single setting operation.

fd+ Means for Solving the Problems This invention provides a system in which a plurality of terminal devices having a timekeeping function are connected via a control device, in which each terminal device has a
a time setting request message sending means for transmitting a time setting request message requesting time setting of the timekeeping function of any other terminal device; A time setting message transmitting means for transmitting a setting message; and a time setting means for setting the time of a timekeeping function in accordance with the message when each terminal device receives the time setting message addressed to its own station. shall be.

(e) Effect In the time setting method of the present invention, when one terminal device sets the time of the timekeeping function and sends a time setting request message to other terminal devices to the effect that they should also set the time, the control The device receives this message and transmits a time setting message to the corresponding terminal device. The terminal device that receives this message sets the time of its timekeeping function according to the contents of the message. Thereby, it is possible to set the time of any other terminal device only by working on one terminal device, and it is possible to extremely efficiently set the time consistent with each terminal device.

ffl Embodiment FIG. 1 is a diagram showing the configuration of a data processing system in which a time setting method according to an embodiment of the present invention is used, and FIG. 2 (A)
, (B) is a block diagram of a control device and a terminal device of the data processing system.

A plurality of terminal bags M2 are connected to the control device 1 via lines. The control device 1 includes a CPU1. ROMII which is controlled by O and stores the system program, RAMI which stores the message received from the terminal device.2. HD
D (hard disk device) 13 and communication circuit 14 ~
There are 16 people.

A plurality of terminal devices 2 are connected to the communication circuits 14 to 16, respectively. The terminal bag N2 is controlled by the CPU 20,
ROM 21 in which basic programs etc. are stored. RAM 22 for storing key input data, etc. keyboard 2
35 Display 24. A card reader 252, a clock circuit 26, and a communication circuit 27 are connected.

FIGS. 3A and 3B are diagrams showing the structure of messages transmitted and received within the same data processing system. (A) in the figure is a time setting request message. This message is transmitted from the terminal device where the time has been set to the control device. It consists of data on the time to be set (year, month, day, day of the week, hour, minute, and second) and the terminal device (setting range: multiple may be used) to set this time. Further, (B) in the same figure is a time setting message.

This message is transmitted from the control device that received the time setting request message to the corresponding terminal device. Transmitting station (control device)
2 Edited as a telegram including the receiving station (terminal device) and the set time. This message is created for each receiving station (terminal device).

FIGS. 4(A) to 4(C) are flowcharts showing the operations of the terminal device and the control device.

FIG. 3A shows the operation of the terminal device in which time setting work is performed. When an input to set the time is made using nl, the time setting mode is entered (n2). The staff member enters the PIN number (n3), and if it is correct, enter the setting range (n4-+n5).
The number of the terminal device to be set is accepted. After that, input of time data is accepted (n6), and these are edited into the message shown in Fig. 3 (A) and sent to the control device (nl
) In the same figure (B), when the control device receives the message shown in FIG. 3 (A) from the terminal device (nlO), it sends this message to the message addressed to each terminal device described in the setting range (see FIG. 3 ( B
)) and sends it to each receiving station (terminal device) (n12) In (C) of the same figure, the terminal device that has received the time setting message from the control device (n13) Please judge whether it is addressed to your station or not.n14)
If it is addressed to your own station, read the time data in the message (n
15), Update the time data of the clock 1 circuit (016)
. If the message is not addressed to your station, ignore it.

The operation in FIG. 4(A) corresponds to the time setting request message transmitting means of the present invention, the operation in FIG. 4(B) corresponds to the time setting request message transmitting means of the present invention, and the operation in FIG. 4(C) corresponds to the time setting request message transmitting means of the present invention. The operation corresponds to the time setting means of the present invention.

(g1 Effect of the Invention As described above, according to the time setting method of the present invention, the time of all necessary terminal devices can be set by only setting the time of one terminal device.Thereby,
It is possible to easily synchronize the time of all terminal devices, realize uniform service, and eliminate wasteful use of communication functions, which is the case when the control device manages the time of all terminal devices. also occurs.
