Abstract

PURPOSE:To detect the abnormality in real time and to quickly cope with this abnormality by using an internal state signal returned from each terminal equipment in response to the request of an abnormality monitor equipment to detect the abnormality and informing a host device of the abnormality via a normal terminal equipment. CONSTITUTION:An abnormality monitor equipment 4 contains a reception part 4a which receives the instruction data from a host device 1, a transmission part 4b which transmits the request signals SR to the terminal equipments 2a - 2n for confirmation of the abnormality, and a reception part 4c which receives the internal state signals SA returned from the equipments 2a - 2n response to the signals SR. Then the equipment 4 checks the signals SA and sends the abnormality signals to the normal ones of equipments 2a - 2n when the abnormality is detected. The abnormality is reported to the device 1 via the normal ones of equipments 2a - 2n. Thus the integrated control is attained to detect the presence or absence of the abnormality of the terminal equipments.

Description

[Detailed Description of the Invention] [Summary] Regarding host centralized management of terminal devices, the purpose is to centrally manage the occurrence of abnormalities in terminal devices in a host device, and an abnormality monitoring device can monitor multiple terminal devices. 1, and each terminal device receives a signal indicating the internal state returned in response to the request signal, and when an abnormality in one of the terminal devices is detected based on the received signal, the abnormality in the terminal device is detected. By outputting an abnormal IM number indicating the occurrence of an abnormality to the terminal device and reporting the occurrence of an abnormality in the terminal device to the -F device via the normal terminal device, the host device can check the status of the entire terminal device installed in the system. Centrally manage J: Configure it as follows.

[Industrial Field of Application] The present invention relates to a method for centrally managing a terminal device host 1 in which a host device centrally manages whether or not there is an abnormality in a plurality of terminal devices connected to a host device.

In a combicoater system in which a plurality of terminal devices are connected around a host device such as a large-sized host computer, one host device can be effectively utilized through the plurality of terminal devices.

By the way, in recent years, these computer systems have become larger and more complex due to the use of communication lines, etc., and the distance between the host equipment and many terminal devices has become long, so that the host equipment can handle all the problems. It is desired to centrally manage abnormalities in terminal devices in real time to ensure normal operation of the entire system.

[Conventional technology] Conventionally, in banking business management systems, product inventory management systems, etc., multiple terminal devices are connected to a host device, and data input from each terminal device is centrally managed or managed by the host device. By reading the data stored in each terminal device, it is possible to effectively utilize the host device and perform real-time processing of the entire large-scale system.

[Problems to be Solved by the Invention] However, in conventional systems, when an abnormality occurs in a terminal device, the host device does not have a function to detect this. It discovered a certain terminal device and took measures such as notifying the host side. In this way, an abnormality in a terminal device cannot be detected unless it is discovered independently on the terminal device side, leading to problems such as a failure to respond quickly to an abnormality in the terminal device.

The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a host centralized management system for terminal devices that allows a host device to centrally manage the occurrence of an abnormality in a terminal device.

[Means to solve the problem] FIG. 1 is a diagram explaining the principle of the present invention.

A host device 1 has a plurality of terminal devices 2a, 2b, ..., 2
The present invention is directed to a host centralized management system that automatically reports an abnormality in each terminal device of a computer system connected via a line 3 to a host device 1.

In contrast to such a host centralized management system for terminal devices, the present invention includes a receiving section 4a that receives instruction data from the host device 1, and a link for abnormality confirmation to each terminal device 2a, 2b, ..., 2n. Transmitter 4b that transmits request signal SR
An abnormality monitoring device 4 is provided, which includes a receiving section 4C that receives an internal status signal 3A returned from each terminal device in response to the request signal SR, and a transmitting section 4b and a receiving section 4C.
and the terminal devices 2a, 2b, ..., 2n is the transmission line LR.
and is connected by a receiving line LA.

[Operation] In the host centralized management system of the present invention having such a configuration, the abnormality monitoring device checks the signal returned from the terminal device in response to the request signal transmitted to the terminal device, and When an abnormality is detected based on the returned signal, it sends an abnormal signal to other normal terminal devices indicating that an abnormality has occurred in one of the terminal devices, and causes the normal terminal device to notify the upper device of C. . By receiving the notification, the host device can centrally manage the abnormality of the terminal device.

[Example] An example of the present invention will be described below with reference to FIG. First, to explain the configuration, in the figure, 1 is a host computer, and a plurality of terminal devices 2a, 2b, . . .・.

2n is connected.

4 is an automatic power-on device, which connects each terminal device 2a, 2b, . . . , 2n according to instructions from the host computer 1.
Turn on the power to start it up, and turn it off to end the operation. Furthermore, the automatic power-on device 4 includes a receiving section 4a that receives instruction data from the host combination "J-Y1".
, a transmitter 4b that issues a request signal 3R for abnormality confirmation to each terminal device 2a, 2b, ..., 2n, and an internal status signal 3A returned from each terminal device in response to the request signal SR. An abnormality monitoring section consisting of a receiving section 4C that receives the information is provided, and a transmission line 1R is provided between the transmitting section 4b and the receiving section 4C and the terminal devices 2a, 2b, ..., 2n.
It is connected to the receiving line IA.

Ru.

The transmitter 4b of the automatic power-on device 4 is connected to each terminal device 2a,
Request signal 3 is periodically sent to 2b, ..., 2n.
When R is transmitted, each terminal device 2a.

2b, ..., 2n are internal state signals SA representing internal states.
is sent back to the transmitter 4b. The reply unit 4b receives the internal status signal S.
If ^ is different from the normal data content, it is determined that an abnormality has occurred, and an abnormality signal is transmitted from the transmitter 4b to each terminal device via the transmission line LR.

A normal terminal device among the terminal devices reports this abnormal signal to the host l-computer 1 via the line 3.

In this way, according to this embodiment, the host combicoater 1 can manage the status of all terminal devices, and
The existing system can be used effectively by installing the 8 power supply device and 1.7 abnormality monitoring section.

[Effects of the Invention] As described above, according to the present invention, an abnormality monitoring device is provided that monitors abnormalities in a plurality of terminal devices, and a response is received from each terminal device in response to a request from the abnormality monitoring device. When an abnormality is detected using the internal status signal, the abnormality is reported to the host device via the normal terminal device, so the abnormality can be detected in real time regardless of whether the terminal device is operating in a manned or unmanned state. , it becomes possible to respond more quickly than before.
