Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a central supervisory control device for centrally supervising and controlling facilities to be supervised such as buildings and plants by computer processing.

[0002]

[Prior art]

 Conventionally, this type of central supervisory control device is constructed by connecting various input / output devices to each channel of the input / output interface of a computer. The various input / output devices include a console such as a keyboard and a monitor display such as a CRT. , Printers, floppy disk devices, hard disk devices, and communication devices for signal transmission used for exchanging supervisory control information and external communication.

Then, the facility to be monitored is centrally monitored and controlled by computer processing based on various kinds of analog and digital monitoring information and operation of the console. The contents of the supervisory control are displayed on the monitor display, printed by a printer by so-called logging processing, and supplied to the floppy disk device and hard disk device to be stored in the floppy disk and hard disk.

In addition, if an interface of any channel, a connection cable or an input / output device fails, or an input / output abnormality occurs due to an abnormality between the input / output interface and each input / output device for some reason, the conventional method is used. Detects the occurrence from the input / output interface port inspection and notifies it to the monitor display.

[0005]

[Problems to be solved by the device]

 In the case of the conventional central supervisory control device described above, when the above-mentioned input / output abnormality occurs, only the occurrence of the input / output abnormality is notified. Therefore, for each channel of the input / output interface, the interface board, connection cable, input It is necessary to repeatedly inspect and replace the output device to detect the location and cause of the abnormality, which requires a lot of labor and time for restoration work. The purpose of the present invention is to reduce the labor and time required for recovery work by quickly identifying the location and cause of an I / O error.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the central supervisory control device of the present invention, the self-diagnosis function of inspecting the state of each part in the device and the self-diagnosis function at the time of abnormality occurrence between the computer and each input / output device are provided. It is provided with a maintenance memory in which inspection results of each part in the device are written as maintenance information, and the maintenance information is read out to a required input / output device.

[0007]

[Action]

 In the case of the central supervisory control device of the present invention configured as described above, when an input / output error occurs, the inspection result of each part in the device at the time of the self-diagnosis function is written in the maintenance memory as maintenance information. The maintenance information written in is read to the required input / output device.

Therefore, when an input / output error occurs, the state of each part in the device is reported in detail on the screen display, etc. Moreover, maintenance information can be transferred to another device, etc. It is possible to quickly understand the cause and the cause and significantly reduce the labor and time required for the recovery work.

[0009]

【Example】

 One embodiment will be described with reference to FIG. As shown in FIG. 1, a computer 1 such as a microcomputer is formed by a central processing unit (hereinafter referred to as a CPU) 2, a memory unit 3 and an input / output interface 4 of a plurality of channels. A central supervisory control device is constructed by connecting various input / output devices such as a key board) 5, a monitor display 6, a printer 7, and a communication device (signal transmission device) 8 for signal transmission.

The memory unit 3 has a ROM holding a program for self-diagnosis together with various programs for supervisory control and a RAM in which various information for supervisory control is written. A part of this RAM is the result of the self-diagnosis. A maintenance memory 9 in which maintenance information is written is formed. The CPU 2 and the memory unit 3 form a self-diagnosis function.

Then, like the conventional apparatus, when the CPU 2 detects an input / output abnormality of any channel from the port inspection of each channel of the input / output interface 4, the CPU 2 executes the self-diagnosis program and executes the self-diagnosis program. The state of each part in the device of the channel where the input / output abnormality is detected is self-diagnosed and inspected, and the inspection result is written in the maintenance memory 9 as holding information.

Therefore, when an input abnormality occurs, detailed information indicating the state of each part in the apparatus at that time is automatically held in the apparatus. Then, the maintenance information written in the maintenance memory 9 is read out to a required input / output device that reports an abnormality by an automatic process based on a self-diagnosis program or an operation of the console 5.

At this time, if the required input / output device is the monitor display 6 and the printer 7, the state of each part in the device is notified in detail by screen display and printing, and the abnormal channel is immediately identified from this notification. It is possible to quickly grasp the abnormal place and the cause. If there is no specialist in the field, the required input / output device is the communication device 8, and the maintenance information is transferred to an external computer device etc. by computer communication via this device 8 and the remote specialized device is used. It enables quick investigation and detection by the house.

Instead of performing the computer communication described above, it is also possible to use a floppy disk device as a required input / output device and use a floppy disk in which maintenance information is written. Therefore, it is possible to reduce the labor and time required for restoration work by quickly grasping the location and cause of an abnormality and taking necessary measures without repeating the complicated inspection and replacement for each channel as in the past. it can.

[0015]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. Equipped with a self-diagnosis function and maintenance memory.When an I / O error occurs, the inspection result of each part of the device at the time of the self-diagnosis function is written to the maintenance memory as maintenance information, and the maintenance information written in this memory is required. Since it is read out to the input / output device of the device, when an input / output error occurs, the state of each part in the device can be informed in detail on the screen display and the maintenance information can be transferred to other devices. As a result, the location and cause of the abnormality can be quickly grasped, and the labor and time required for restoration work can be greatly reduced.
