[0002]

2. Description of the Related Art Conventionally, a building or the like has been provided with a remote monitoring device for monitoring building equipment (for example, substation equipment, air conditioning equipment or security equipment, etc.). In some cases, it is not possible to detect an abnormality in the building equipment only from information notified from the monitoring device to the monitoring center, and improvement is desired.

A conventional remote monitoring device is installed in a building, and is connected to a monitoring center installed in a place other than the building via a public line or the like. The remote monitoring device has a function of detecting the operating state (run and stop, etc.) of a plurality of building equipment with sensors provided respectively, and transmitting a detection signal from the sensor to a monitoring center when an abnormality occurs, and is used in a building. It has a function of reading measurement data of an instrument for measuring the amount of electric power, room temperature, and the like at predetermined time intervals, for example, every hour, and transmitting the data to the monitoring center in the same manner as described above.

[0004] For example, in remote monitoring using a sensor, although the response to the state change of each building facility is quick, there are many false reports and false detections, and every time an abnormality occurs, it is necessary for a maintenance worker to go to the site and respond.

[0005] For example, when an abnormality is detected by a smoke sensor or the like installed in a building, a detection signal of the sensor that detects the smoke is reported from the remote monitoring device to the monitoring center. Even if maintenance personnel rush from the center to the site where the building is located, it may not be possible to detect abnormalities due to smoke. In addition, even if many other sensors and meters detect anomalies, not only smoke sensors, but recent building equipment is becoming more and more high-tech. In some cases, maintenance personnel cannot find the abnormal location.

Therefore, even if the technical skills of the maintenance personnel are improved, each of the maintenance personnel cannot be made a specialist capable of coping with the abnormality of all the building equipment. The ratio is limited to the assignment of highly skilled specialists.

[0007] In this case, a specialist cannot run in every time the building equipment becomes abnormal, and a maintenance person must take measures when an abnormality occurs.

[0008]

As described above, according to the conventional remote monitoring device, the abnormality of the building equipment is notified to the monitoring center only by the detection signal from the sensor or the measurement data. However, there is a problem that it is not possible to accurately cope with equipment abnormality because of the failure. Also, since the monitoring center and the remote monitoring device are connected by a public line or the like, and the communication fee greatly depends on the data amount of the measurement data and the communication time zone, if the measurement data is transmitted every predetermined time, the monitoring will not be performed. Costly.

The present invention has been made in order to solve such a problem, and it is possible to accurately and easily grasp the state of occurrence of an abnormality. It is an object of the present invention to provide a remote monitoring device that can cope with the problem and reduce the monitoring cost.

Next, the operation of the remote monitoring device 1 will be described.

In the case of the remote monitoring device 1, each building facility 6
A sensor signal from the sensor group 7 provided at
Input to the remote monitoring device 1 via the I / O device 2,
The building equipment 6 is constantly monitored by the remote monitoring device 1.

Here, among the input signals (sensor signals) input to the remote monitoring device 1, if there is a state change in the digital signal indicating the operation of the equipment, a stop signal, an abnormal signal, etc., the date and the occurrence time In addition to generating and storing history data with the addition of, for example, when the state change requires responsiveness, the history data is immediately reported to the monitoring center 3. Further, the maintenance staff uses the telephone 8 to notify the remote monitoring device 1 of the failure status of the building equipment 6, photograph the abnormal status with a digital camera, a video camera, or the like. When the user takes the camera back to a certain place and inputs the photographing data to the remote monitoring device 1, the photographing data is input to the image editing unit 16 via the image data processing unit 15. The image editing unit 16
It is determined which device the input photographing data is really necessary data, deletes unnecessary data, and transmits the data to the abnormality determination processing unit 17. In the abnormality determination processing unit 17,
A primary diagnosis of an abnormality is performed based on the input photographing data and the history data. By connecting a digital camera, a video camera, or the like to a portable terminal such as a PHS, for example, the portable terminal and the remote monitoring device 1 perform wireless communication, and input work to the remote monitoring device 1 can also be performed on site. .

Further, in the remote monitoring device 1, the voice editing unit 14 determines the content of the conversation service with the maintenance staff and notifies the abnormality determination processing unit 17. The abnormality determination processing unit 17 performs the primary diagnosis operation of the abnormality in consideration of the content of the determination. Conversation services include telephone services, primary diagnostic services,
There is a patrol service. For example, in the case of the primary diagnosis service, the device name and the status are put together by message exchange (dialogue) with the maintenance staff and stored in the data file processing unit 11.

The following is a specific example of a conversation service when an abnormality occurs in the air conditioner.

First, the maintenance person goes to the place where the equipment in which the abnormality has occurred is installed.

When the maintenance person arrives at the site, he picks up the telephone 8 and
Go to the front of the on-site monitoring panel indicating an abnormality. Then, in order to receive the conversation service, call # 0 using the button of the telephone 8. Then, the remote monitoring device 1 transmits a response message to # 0 to the telephone 8. The response message is, for example, "Conversation service. Enter "1" for conversation service, "2" for primary diagnosis service, and "3" for patrol service after the beep. ].

When the maintenance staff listens to the response message using the telephone receiver of the telephone 8 and inputs "2" of the primary diagnostic service with the button of the telephone 8, then the remote monitoring device 1 transmits "2 to the on-site monitoring panel air conditioner # 1". Are the red and yellow lights on? Is sent.

In response to this message, the maintenance staff answers the telephone 8 "The abnormal lamp is lit in yellow." Then, the remote monitoring device 1 asks the user, "Is the airflow larger than the set value?" ? Is sent, the maintenance worker answers "less" to the telephone 8.

By repeating the dialogue with the maintenance staff in this way, the remote monitoring device 1 makes a primary diagnosis, and the diagnosis result is "Cleaning of the filter is considered to be due to clogging of the filter." To maintenance personnel.

The maintenance staff listens to the result of the diagnosis with the receiver, removes the filter from the air conditioner, cleans it, attaches the filter to the air conditioner, confirms that the abnormal lamp on the monitoring panel has been turned off, and displays on the telephone 8 "The abnormal lamp has been turned off. "
When # 1 or the like is called using the button of the telephone 8, the remote monitoring device 1 recognizes the completion of the work and ends the conversation service. As a result, a series of operations can be completed by one maintenance person without special expertise. Further, the remote monitoring device 1 stores the contents of the above-described dialogue with the maintenance staff and the results of the diagnosis in the data file processing unit 11, and then, based on the device name, stores the device ledger in which the information about the device is input into a magnetic field. Since the data is read from the disk device or the MO device and displayed on the monitor of the remote monitoring device 1 itself, the maintenance staff can know the device specifications, the failure history, and the repair history from the device ledger displayed on the monitor.

Further, the device name is converted into a unique device number and transmitted to the abnormality determination processing unit 17 together with the voice data of the situation at the site.

The abnormality determination processing unit 17 generates data (abnormality data) indicating an abnormality in the building equipment based on the audio and image data sent from the audio editing unit 14 and the image editing unit 16, respectively. Data file processing unit 1
Save to 1. The result of the abnormality determination performed by the abnormality determination processing unit 17 is transmitted to the building facility 6 where the abnormality has occurred through the voice editing unit 14 and the voice processing unit 13 so that the maintenance staff can listen to the information using the telephone 8 of the building facility 6. Can be.

The abnormality determination processing unit 17 includes, for example, data stored in the data file processing unit 11 and data stored in the past, for example.
Compare with about 100 abnormal data and make a primary diagnosis of the same kind of abnormal failure. When the current abnormal data and the past abnormal data match according to the primary diagnosis, a response method and a repair status for the device are transmitted to the telephone 8 through the voice editing unit 14 and the Ise processing unit 13. If the data does not match, the current abnormal data is sent to the transmission data discrimination processing unit 18 and only necessary data is discriminated (sorted), and then the transmission processing unit 5 sends the data to the public line 20 or ISDN.
The abnormal data is transmitted to the monitoring center 3 via the line 21.

In the monitoring center 3, the transmitted abnormal data and the past data stored in the center, for example, 10
A search is performed to compare with about 00 abnormal data. If there is a similar case in the past as a result of the search, the monitoring center 3 transmits information on the response method and the repair status to the remote monitoring device 1.

When the remote monitoring device 1 receives information on the response method and the repair status from the monitoring center 3, the remote monitoring device 1 notifies the telephone 8 via the I / O device 2 of the information from the voice editing unit 14 and the voice processing unit 13, On-site maintenance staff can hear the response method and repair status.

The transmission data discrimination processing section 18 classifies the data sent from the data file processing section 11, the state change detection processing section 12, and the abnormality discrimination processing section 17 for each data type. Determine the transmission timing.

For example, the data type from the state change detection processing unit 12 is transmitted to the monitoring center 3 unconditionally. The transmission processing unit 5 takes out the transmission data written by the transmission data discrimination processing unit 18, and according to the data type, the public line 20.
Alternatively, of the ISDN lines 21, a line is selected from the one with a low cost or the one with a high speed, and the line is transmitted to the monitoring center 3 using the one that meets the situation.

On the other hand, analog signals such as the temperature and humidity of each room and the current of the pump, and sensor signals such as pulse input signals such as the amount of water and gas used, have a constant period (one minute, one minute) regardless of the presence or absence of abnormality. The data is taken into the remote monitoring device 1 every time) and stored in the data file processing unit 11 inside the device. The data stored in the data file processing unit 11 is transmitted to the monitoring center 3 at a predetermined time, for example, at a late-night time when the line usage fee is relatively low.

As described above, according to the remote monitoring apparatus of this embodiment, among the status signals, signals that require responsiveness such as an abnormal signal are immediately transmitted to the monitoring center 3 while the data file processing unit 11 Is transmitted to the monitoring center 3 at a time such as a late-night time when the line usage fee is relatively low. Urgency) can be determined accurately and easily, and monitoring work can be performed without confusion. In addition, since the data file is transmitted at a time when the line usage fee is relatively low, such as at midnight, the communication fee can be reduced and the monitoring cost can be reduced.

Also, the maintenance staff notifies the remote monitoring device 1 of the situation of the building equipment 6 in which the abnormality has occurred by using voice data using the telephone 8 and image data using a digital camera, a video camera or the like, and performs remote monitoring. The device 1 generates abnormal data based on the audio and image data and stores the data in the device or transmits the data to the monitoring center 3, so that the maintenance staff of the monitoring center 3 can accurately determine the abnormal situation. In addition, since the monitoring center 3 notifies the telephone 8 of a method of responding to the details of a failure that has occurred in the past, the maintenance staff who hears the notification can promptly deal with the building equipment and reduce the time to recover from the failure (failure). Can be shortened. In addition, this allows the maintenance staff to deal with the problem even if they are not experts in building equipment maintenance, and can reduce the burden of monitoring.

Since an abnormal situation can be accurately determined, for example, for a small-scale trouble, a maintenance person who has rushed to the site checks the history information of the building equipment stored in the remote monitoring device 1 to repair the trouble. Maintenance can be performed. Further, by storing a series of abnormal recovery status data from the occurrence of an abnormality to the repair, each time, the data can be used for maintenance of building equipment and prevention of failure in the future.

[0045]

As described above, according to the present invention, an abnormal state can be accurately and easily grasped. In addition, small-scale troubles can be dealt with without the maintenance staff having specialized skills. Further, monitoring costs can be reduced.
