Abstract

PROBLEM TO BE SOLVED: To provide an automatic fault guidance display device for monitoring device, with which an observer can quickly deal with a fault when that fault occurs in a monitor object system. SOLUTION: In the automatic fault guidance display device for the dual monitoring device in the system utilized for various fields such as industry, traffic, building or public facilities, a controller for monitoring the system is doubled and when one controller is down, the other controller acquires the control of the system and the abnormal state of the system. Then, a monitor is connected to that controller and the operating conditions of the system can be monitored by this monitor. Therefore, since guidance is displayed on the monitor simultaneously with the fault that occurs, the observer can quickly deal with the fault.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a failure guidance automatic display device for a monitoring device for monitoring a system used in various fields such as industry, traffic, buildings, public facilities and the like.

[0002]

2. Description of the Related Art In a conventional monitoring apparatus for monitoring a system used in various fields such as industry, traffic, buildings, public facilities, etc., a duplicated monitor is used. Otherwise, the same display is always displayed. If a failure to be monitored occurs, the same screen is displayed on both monitors by automatic display or the like. Further, even if it is known that a failure has occurred, a mechanism for immediately recognizing a countermeasure has not been established.

[0003]

Further, in the conventional monitoring system, not every monitor can immediately know how to cope even if the monitor detects that a failure has occurred in a device of the monitored system. In some cases, urgent action is required. If you do not immediately know how to deal with it, the damage may spread. In addition, even inexperienced observers need to be able to quickly understand the coping method.

By the way, the two duplicated monitors are:
In many cases, it is not always necessary to display the same content. For example, both monitors not only function as duplicates, but also if one monitor displays a faulty item, the other monitor describes how to respond to the fault, to assist a watchman monitoring the system. It is desired that guidance be displayed and that as much information as possible be provided to the observer when an abnormal situation occurs.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a monitoring system that, when an abnormal state such as a failure occurs in a monitored system, displays the generated failure or the like and displays guidance at the same time. Is to provide a failure guidance automatic display device of a monitoring device capable of promptly coping with the failure or the like.

[0006]

In order to achieve the above object, the invention according to claim 1 is duplicated for monitoring systems used in various fields such as industry, transportation, buildings, public facilities and the like. In the failure guidance automatic display device of the monitoring device, a controller for monitoring the system is duplicated, and one of the controllers controls the system when the other controller goes down, and acquires an abnormal state of the system, The abnormal state and the guidance thereof are simultaneously displayed by a monitor connected to the controller.

According to the first aspect of the invention, when an abnormal state occurs in the monitored system, the abnormal state is displayed and the guidance is displayed at the same time, so that the monitor can promptly deal with the failure.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram of a monitoring device according to a first embodiment of the present invention. As shown in the figure, in the present embodiment, two sets of a controller 1 and a monitor 2 connected to the controller 1 are prepared, and the controllers 1 are connected to each other.

In a system used in various fields such as industry, transportation, buildings, public facilities, etc., when an abnormal state such as a failure occurs, the controller displays a failure item in the execution section of the controller. If you decide to display, and to display guidance,
Determine which guidance is appropriate to present.

The duplex system of the present invention has a concept of a master system and a slave system, and only a controller of the master system can output control to the system. If the main controller goes down for some reason, the subordinate controller immediately becomes the main system, and the monitoring of the system can be continued without interruption.

When both the controller and the monitor are operating normally, a function for automatically displaying a failure guidance is provided. Therefore, when an abnormal state such as a failure does not occur, a monitor can freely operate both the monitors and the monitor. Each screen can be viewed freely.

However, when an abnormal state such as a failure occurs in the system, the main controller displays a failure item, a location, and the like on a monitor connected to the own controller, and notifies a monitor staff with a sound of a buzzer. At the same time, the slave controller displays the guidance stored according to the failure item that has occurred, and informs the observer of the action to be taken promptly.

FIG. 2 is a functional block diagram of the controller of the present invention. The status of the monitored system,
The failure is received by the input unit 3 of the controller 1. The information is transferred to the execution unit 4 and passed to the output unit 5 and the display unit 6 according to the operation programmed in advance.

When a system failure occurs, the display is sent to the display unit 6. When the controller 1 is the main system, the display unit 6 sets the system to inform the monitor 2 that the failure has occurred. The information is transmitted from the execution unit 4 to the other controller 1 via the transmission unit 8. In the case of slaves,
An appropriate guidance for the fault that has occurred is selected from the storage unit 7 and set to be displayed on the monitor 2.

FIG. 3 is a flowchart showing the actual operation of the controller. It is constantly monitored whether there is a failure in the system to be monitored (step 101). If there is a failure, it is determined whether the own controller is a master system or a slave system (step 102). If it is the main system, an instruction is given to display a failure display screen showing the details of the failure on the monitor (step 10).
3) If it is a subordinate, an appropriate guidance for the occurred failure is selected and instructed to be displayed on the monitor (step 104). In addition, an input from the operator is received (step 105), and a screen display corresponding thereto and a system status signal received by the controller are displayed (step 106).

The above is an example in which both the controller and the monitor are operating normally. If one of the controllers or the monitor is abnormal, the system can be monitored by the normal controller and the monitor. When a system failure occurs, the failure details and guidance are displayed on the failure display screen of the monitor. However, since the display of the failure content must be given priority, the guidance is not automatically displayed, but is displayed by the operation of the operator.

[0017]

As described above, according to the present invention,
When a failure occurs in the monitored system, the failure is displayed and the guidance is displayed at the same time, so that the supervisor can quickly respond to the failure.
