DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for inspecting equipment in a substation or the like where a patrol inspector patrols and performs maintenance and inspection, and transmits it to a monitoring center.

[0002]

2. Description of the Related Art In a substation of a power company, it is necessary to safely transmit power transmitted from a power plant to a next substation or a customer. If a device installed in a substation breaks down, an accident such as unstable voltage fluctuation or power outage will be caused. In order to prevent this, it is necessary to perform maintenance and inspection of various equipment installed in the substation. Usually, a patrol inspector goes to the site and patrols each device for maintenance and inspection of the device. The patrol inspector and the integrated monitoring center are able to communicate with each other wirelessly so that a plurality of substation equipment can be maintained and inspected.

Conventionally, maintenance and inspection of such equipment are performed, for example, by using a portable input / output device (portable terminal device) capable of transmitting data and manually transmitting inspection result data to a comprehensive monitoring center. I have to. However, since the patrol inspector manually inputs all inspection results while looking at a predetermined menu, there is a disadvantage that erroneous input, inspection omission, or the like occurs.

In order to solve this problem, the inspection result of the equipment inspected by the patrol inspector is reported to the general monitoring center by voice, and the inspection result is recognized by the voice recognition device and stored in the storage device. Automatically sets the next inspection item from the center
There is also known an apparatus in which a patrol inspector is instructed by a voice communication device such as an HS (simplified mobile phone system) to sequentially perform inspections.

More specifically, a control device, a voice recognition device, and a PHS storing a voice dictionary and a voice check system (voice check program) are installed in the integrated monitoring center, and wirelessly communicate with a PHS of a patrol checker. And the inspection result of the patrol inspector is received by the voice recognition device. If the result is "good", it is confirmed by the voice inspection system. If there is no problem, the word "good" is extracted from the voice dictionary and the confirmation answer is notified to the patrol inspector by voice. After a predetermined time, the next inspection item is extracted from the program of the control device, and a voice, for example, "Is the pressure gauge indication good?" Is extracted from the voice dictionary and transmitted to the patrol inspector. Hereinafter, maintenance and inspection are performed by the same mutual communication as described above.

In the inspection of equipment, not only the inspection result of the equipment is “good” or “absent”, but also an item for reporting an indicated value (numerical value) of an indicating instrument. In the former case, the pronunciation is simple and can be accurately and easily recognized by the speech recognition device. However, the latter instrument indication value has an infinite number of combinations and digits.

[0007]

In the prior art, the indicating value (numerical value) of the indicating instrument is also reported by voice. The speech recognition device has a poor recognition rate of numerical values and it is difficult to recognize numerical values accurately.In particular, there is no problem when the number of digits is small, but it takes a long time even if the number of digits is large. become.

Therefore, it may take a long time before the next inspection command is issued from the integrated monitoring center, or the next inspection command may be temporarily stopped due to erroneous recognition or an erroneous determination may be made.
As a result, there is a problem that the maintenance and inspection of the equipment by the patrol inspector cannot be performed smoothly.

An object of the present invention is to provide an inspection apparatus for equipment that can smoothly perform maintenance and inspection of the equipment by a patrol inspector.

[0010]

A feature of the present invention is that a patrol inspector transmits the inspection result of equipment by voice and inputs an indicated value of an indicating instrument to a portable terminal device. Radio transmission.

According to the present invention, the indicated value of the indicating instrument is input to the portable terminal device and transmitted wirelessly, so that even if the indicated value has a large number of digits, it can be accurately recognized by the integrated monitoring center. Accordingly, maintenance and inspection of the equipment by the patrol inspector can be smoothly performed.

A voice recognition device 8, a supervisory control device (PC) 9, a LAN (local area network) 10, a voice dictionary and a voice inspection system stored in a storage device (not shown);
Another monitoring system 11 is provided.

In this configuration, a patrol inspector 3 goes to the substation 1 for periodic inspections and performs a patrol inspection of the equipment 2. The patrol inspector 3 performs a patrol inspection of the device 2 and transmits the inspection result to the voice communication device 7 of the general monitoring center 6 by voice communication using the voice communication device 4. The inspection information (voice information) received by the voice communication device 7 is recognized by the voice recognition device 8 and input to the monitoring control device 9.

When the inspection result is "good", the monitoring and control device 9 checks with the voice inspection system and if there is no problem, derives the word "good" from the voice dictionary and sends the confirmation answer to the patrol inspector 3 by the voice communication device. 4 via voice.
After a predetermined time, the monitoring control device 9 extracts the next check item from the program of the voice check system, extracts a voice such as "Is the pressure gauge indication good?" From the voice dictionary, and conveys it to the patrol checker 3. Hereinafter, a cyclic inspection of the device 2 is performed while performing the same mutual communication.

As described above, when the inspection result of the device 2 is communicated to the general monitoring center 6 by voice communication, the indication value of the indicating instrument is communicated to the general monitoring center 6 by the portable terminal device 5. The patrol inspector 3 has the portable terminal device 5, and when reporting the instrument indicated value, manually inputs the value to the portable terminal device 5. The patrol inspector 3 notifies the portable terminal device 5 of the fact by using the voice transmission device 4 before inputting the instrument instruction value to the portable terminal device 5. The general monitoring center 6 receives the input of the instrument indication value by the voice communication device 7 and recognizes that the instrument recognition value is reported by the speech recognition device 8.

When the voice recognition device 8 recognizes this, the voice check system of the monitoring control device 9 determines the address to which the instrument instruction value is to be input. The portable terminal device 5 has a function capable of wireless transmission.
Is transmitted to the portable terminal device 5 and displayed. After inspecting the address displayed on the portable terminal device 5, the patrol inspector 3 manually inputs an instrument instruction value to the portable terminal device 5.
