As a method for transmitting data from the remote monitoring terminal 2 to the communication unit 3, wired communication via a signal cable may be used as described above, but wireless communication may be used. Good.

The remote monitoring terminal 2 detects an abnormality in a predetermined monitoring item with respect to the corresponding power equipment 1 and detects the abnormality and generates an abnormality such as when and what abnormality occurred in which monitoring item. The error information including the contents is output to communication cut 3. The remote monitoring terminal 2 also detects the occurrence of an abnormality when it has recovered, and outputs to the communication unit 3 abnormality information indicating when and how the monitoring item was recovered and how. Further, the remote monitoring terminal 2 stores the monitoring result of a predetermined monitoring item regardless of whether or not an abnormality occurs in the power equipment 1, and transmits the stored monitoring result to the communication unit at predetermined time intervals (for example, every day). Output to 3 Here, the items to be monitored by the remote monitoring terminal 2 can be arbitrarily set for each power equipment 1 with the monitoring items required for the maintenance of the power equipment 1. It may be set appropriately. For example, low-voltage power receiving equipment stipulated by the Electricity Business Act of Japan 保守 maintenance items for small-scale power generating equipment (disclosure of guidance information, parallel congestion, engine stall, engine acceleration, cooling water temperature information, lubricating oil pressure drop, Overcurrent, overload, reverse current, undervoltage, tracking error, generator power, generator power, bus voltage, additional power, inverter output voltage, engine speed, etc.) can be set as monitoring items. .

The communication unit 3 is connected to a packet communication network 4. The communication unit 3 can perform packet communication with another communication device connected to the packet communication network 4 via the base station 5 of the packet communication network 4. In addition, when the remote monitoring terminal 2 supplies abnormality information indicating the occurrence of an abnormality or the recovery of an abnormality for a predetermined monitoring item, the communication unit 3 monitors the monitoring item in which the abnormality has occurred or has been recovered, the time when the abnormality has occurred, or the recovery time.

Further, the communication unit 3 transmits monitoring result information supplied from the remote monitoring terminal 2 at predetermined intervals to the remote monitoring center 6 via the packet communication network 4 irrespective of the presence or absence of an abnormality. Here, when transmitting data from the communication unit 3 to the remote monitoring center 6, Packet communication via the packet communication network 4 is used. In this way, the remote monitoring center 6 can detect which power equipment has an abnormality, etc., based on the abnormality information transmitted from the communication unit 3. Therefore, the identification information included in the abnormality information only needs to be information that can identify which power equipment is used, and is not limited to simply converting the power equipment name into data, but is also numerically encoded. You may. When the power equipment 1 and the communication unit 3 are provided in a one-to-one correspondence, the remote monitoring center 6 does not include the power equipment name in the above-mentioned abnormality information, and the transmission source information of the abnormality information By specifying the communication unit 3, the power equipment corresponding to the communication unit 3 may be identified.

A large number (two shown) of such power facilities 1 and remote monitoring terminals 2 and communication packets 3 provided correspondingly in the area of the base station 5 of the packet communication network 4. If an abnormality occurs in a predetermined monitoring item of a certain power facility 1 among the power facilities 1 existing in the area of the base station 5, the communication corresponding to the power facility 1 is performed. The abnormal information is transmitted from the unit 3 to the remote monitoring center 6 via the bucket communication network 4. Therefore, in the present embodiment, the remote monitoring terminal 2 and the communication unit 3 constitute an information transmitting device as claimed, and the packet communication network 4 constitutes a first communication network. In the present embodiment, the remote monitoring terminal 2 and the communication unit 3 are separate devices, but they may be a single device.

Communication with devices connected to other networks It is possible to perform bidirectional bucket data communication between them.

Further, the mobile terminal 10 has a unique e-mail address, and has an e-mail reception function capable of receiving an e-mail transmitted to the e-mail address via the packet communication network 8, It has an e-mail transmission function of transmitting an e-mail to the remote monitoring center 6 connected to the packet communication network 8 via the router 7 and other portable terminals 10. Further, it is also possible to send an e-mail to another device connected to the Internet or the like via the packet communication network 8. Further, the mobile terminal 10 is connected to a mobile telephone network (not shown), and can receive general mobile telephone services.

B. Configuration of Remote Monitoring Center

Next, the remote monitoring center 6 comprises a single personal computer (PC) or a computer system such as a database server or a personal computer connected to a LAN (Local Area Network). The CPU (Central Processing Unit) mounted on the PC executes various programs to execute various functions.

Here, FIG. 2 is a block diagram showing the functional configuration of the remote monitoring center 6. The functional configuration of the remote monitoring center 6 will be described below with reference to FIG. As shown in the figure, the remote monitoring center 6 includes a transmission / reception unit 21, a notification processing unit 22, an abnormality detail information creation unit 23, a history information creation unit 24, and a security database 25. And a monitoring history 'abnormality detail database 26'.

The transmission / reception unit 21 is a communication interface for transmitting / receiving data to / from another device connected to the bucket communication network 4 or the packet communication network 8 via the router 7 shown in FIG. When abnormal information is transmitted from the communication unit 3 (see FIG. 1), the transmitting / receiving unit 21 receives the abnormal information I J and outputs it to the notification processing unit 22 and the abnormal detailed information creating unit 23. Further, the transmission / reception unit 21 receives monitoring history information transmitted from the communication unit 3 (see FIG. 1) at predetermined intervals, and outputs the received monitoring history information K to the history information creation unit 24.

Upon receiving the abnormality information IJ from the transmission / reception unit 21, the notification processing unit 22 refers to the security person database 25 to obtain the power indicated in the supplied abnormality information IJ. Select a security person to send an e-mail based on the equipment name. Then, the notification processing unit 22 generates an e-mail message for notifying the occurrence / recovery of the abnormality and transmits the generated e-mail message to the portable terminal 10 owned by the selected security guard. M is output to the transmission / reception unit 21. As a result, an e-mail containing a message for notifying the occurrence of an error from the transmission / reception unit 21 to the mobile terminal 10 owned by the security person identified via the router 7 and the packet communication network 8. Sent.

Here, the e-mail message for announcing the occurrence / recovery of the abnormality only needs to include at least the name of the power equipment and information indicating that the abnormality has occurred or has been recovered. In the present embodiment, the message created by the notification processing unit 22 includes the name of the power equipment in which the error occurred / recovered, the name of the monitoring item in which the error occurred / recovered, the date and time the error occurred / recovered, and the error described later. Monitoring history with detailed information posted · Address information (for example, URL (Uniform Resource Locators)) for accessing the contents of the abnormal detail database 26 is included. The display as shown in FIG. 3 is displayed on the display screen of the portable terminal 10 that has received the e-mail message. As shown in FIG. 3, the abnormality notification e-mail sent to the mobile terminal 10 includes a message such as “Please return the e-mail for confirmation of receipt”. In other words, a business operator that provides remote monitoring service using this remote monitoring system must be able to respond to the occurrence of the abnormality if the security person who has received the e-mail for notifying the occurrence of the abnormality can respond to the occurrence of the abnormality. An agreement is stipulated to return the receipt confirmation mail to the remote monitoring center 6. Therefore, if the security person who referred to the e-mail can go to the site where the abnormality occurred, etc., the mobile terminal 10 specifies a predetermined e-mail address addressed to the remote monitoring center 6 and returns a reception confirmation mail. .

As shown in Fig. 4, the security database 25 contains, for each power facility 1 that receives a remote monitoring service using this remote monitoring system, the name of the person in charge and the area in which the power facility is in charge. If you have the same area security information that indicates the name of the security person, the e-mail address information of the mobile device 10 owned by these security people, and the e-mail address other than the e-mail other than the mobile device 10 The e-mail address information and the like are stored. The notification processor 22 sends such information to each power setting. Refer to the security database 25 stored for each equipment 1 to select a security person.

When the abnormality information IJ is supplied from the transmission / reception unit 21, the abnormality detailed information creation unit 23 monitors the contents of the abnormality included in the received abnormality information IJ in the monitoring history and the abnormality details stored in the abnormality detail database 26. Add to detailed information. That is, the contents of the detailed abnormality information stored in the monitoring history / detailed abnormality database 26 are updated. Here, the monitoring history / abnormality database 26 contains the type information of all power facilities 1 that receive the monitoring service by the remote monitoring center 6 (information such as whether the facility is a power generation facility or a power receiving facility), Address and phone number information, detailed information on abnormalities including past abnormalities and their recovery, or the reason for the abnormality's recovery are in a format accessible from each mobile terminal 10 (for example, CHTML (Compact Hyper Text Text). Markup Language) and HDML (Handheld Device Markup Language)). In other words, the monitoring history / abnormality database 26 stores detailed information on the power equipment that is not included in the above-mentioned notification e-mail. Therefore, each security person operates the portable terminal 10 to access the monitoring detail / abnormality information stored in the abnormality detail database 26 via the bucket communication network 8 so as to obtain these information. This information can be received via the packet communication network 8 and the like, and can be displayed on the display unit of the mobile terminal 10. The abnormality detailed information creation unit 23 is configured to allow the detailed abnormality information to be referred to from a personal computer or the like connected to the Internet in addition to the data in a format accessible from the portable terminal 10 as described above. It may be stored as data in HTML (Hyper Text Markup Language) format.

When the monitoring result information K is supplied from the transmitting / receiving unit 21, the history information creating unit 24 accumulates the supplied monitoring result information K in the monitoring history / abnormality detail database 26. Here, the accumulated monitoring result information K is edited by a predetermined document creation application, and is stored in the monitoring history / abnormality detail database 26 as a document file in a predetermined format. This is stored as a document file of the monitoring history information KR that can be downloaded from other communication devices via the packet communication network 4. Here, the predetermined format can be appropriately set by the administrator of the remote monitoring center 6 as necessary. Wear. For example, the Electricity Business Act in Japan requires that documents of monitoring history information for high- and low-voltage power supply facilities be submitted. Therefore, it is only necessary to set so that a document file according to the monitoring items and format according to this rule is automatically created. By making such settings, if a document file of the monitoring history information is downloaded from the monitoring history / abnormality database 26 to a personal computer owned by a security person or the like via a network such as the Internet, the relevant Documents for submission can be created by printing without performing document editing work on a Sonal Computer or the like.

As described above, the transmission / reception unit 21 monitors the monitoring history by the abnormality detail information creating unit 23 and the history information creating unit 24. The abnormality detail information IS and the monitoring history information KR stored in the abnormality detail database 26 are transmitted to an external terminal. Send. More specifically, when the transmission / reception unit 21 receives an access request from a terminal device such as the mobile terminal 10 or a personal computer, the transmission / reception unit 21 transmits the detailed abnormality information IS and the monitoring history information KR specified in the access request. Monitoring history. Read from the abnormal detail database 26 and send it to the requested terminal.

C. Operation of remote monitoring center

Next, the operation of the remote monitoring center 6 having the above configuration will be described. As described above, the notification processing unit 22 in the remote monitoring center 6 performs a notification process at predetermined intervals to send an e-mail to the security person to notify the security person when an error occurs and Z is recovered. First, the notification process will be described with reference to FIG.

As shown in the figure, in the notification process, first, it is determined whether or not abnormal information has been received from any of the communication units 3 (step Sa1). Here, if no abnormal information has been received from any of the communication units 3, the notification processing ends.

On the other hand, if abnormality information is received from any of the communication units 3, the abnormality specified by the received abnormality information occurs or is recovered by referring to the monitoring history and abnormality detail database 26. The security officer in charge of the power equipment is selected. Then, an e-mail notifying of the occurrence / recovery of the abnormality is transmitted to the portable terminal 10 owned by the selected security officer (step Sa2). In this case, the security officer in charge is If the user has an e-mail address other than 0 and this e-mail address is registered in the security database 25, the same e-mail for notification is sent to this e-mail address.

After sending the e-mail to the mobile terminal 10 owned by the security officer in charge, it is determined whether or not the reception confirmation mail from the mobile terminal 10 has been received within a predetermined time (step Sa). 3). As described above, in this remote monitoring system, when a security person receives an electronic mail for notification on the portable terminal 10, there is an agreement that a security confirmation mail should be returned to the remote monitoring center 6. For this reason, if the acknowledgment mail from the mobile terminal 10 of the security officer in charge has not been received by the remote monitoring center 6, the security officer in charge has not noticed the e-mail for notification sent to the mobile terminal 10 However, if the security officer in charge is out of the communication area of the packet communication network 8, or has received an e-mail, but has not received the notification e-mail due to the inability of the security officer to respond to the occurrence of an abnormality, etc. Conceivable. Therefore, if the e-mail transmission does not receive the receipt confirmation e-mail from the security officer in charge after the elapse of the predetermined time (determination "NO" in step Sa3), the security officer moves to the site where the abnormality occurred. It is determined that it cannot be dealt with, and a security person in place of the security person in charge is selected based on the same area security information registered in the security database 25 (Step Sa 4). Specifically, a security officer who is in charge of the same area as the power equipment where the abnormality occurred / recovered is selected. If there is more than one person in charge in the same area, priorities should be set among these security officers in advance, and a security officer with a higher priority should be selected.

When the security person is selected in this way, an e-mail for notification is sent to the mobile terminal 10 owned by the selected security agent (step Sa5). Also when transmitting this e-mail, if an e-mail address other than the mobile terminal 10 is registered in the security database 25, the e-mail is sent to the e-mail address.

After sending the notification e-mail to the mobile terminal 10 possessed by the proxy security agent selected based on the same area security information as described above, the reception confirmation mail from the mobile terminal 10 within a predetermined time Is determined (step Sa6). At this point, if a specified time has not passed since the e-mail was sent, and the reception confirmation e-mail has not been received from the selected surrogate security officer, this fact is notified to the administrator of this remote monitoring system. Then (step Sa7), the notification process ends. If a confirmation email is not received from the surrogate security officer, and another security officer in charge of the same area of the power equipment where the abnormality has occurred is registered, It is only necessary to select the person as a security person and perform the processing from step Sa4. On the other hand, if a receipt confirmation e-mail is received from the security officer in charge (determination "YES" in step Sa3), the security officer in charge is notified of the occurrence / recovery of the abnormality, and the security officer in charge responds to the occurrence of the abnormality. It is determined that the notification is possible, that is, it is determined that the notification of the occurrence of the abnormality has been normally performed, and the notification process ends. Also, when a receipt confirmation e-mail is received from the selected surrogate security officer (determination “YES” in step Sa 6), the surrogate security officer is notified of the occurrence / recovery, and the surrogate security officer is notified of the occurrence of the abnormality. It is determined that it is possible to respond to the error, that is, it is determined that the notification of the occurrence of the abnormality has been normally performed, and the notification process is terminated.

The determination as to whether or not the reception confirmation mail has been received in step Sa3 and step Sa6 described above may be performed by the following method. If the e-mail is sent once to the security person and the reception confirmation e-mail is not received within the specified time, the e-mail is sent again to the mobile terminal 10 owned by the same security person, and then within the specified time It may be determined whether or not a receipt confirmation mail has been received. In addition, after such an e-mail resending process is repeated a predetermined number of times, if a receipt confirmation e-mail is not received, a process of selecting a substitute security officer (step Sa 4) and a process of notifying the administrator (step Sa It may be possible to shift to 7).

What has been described above is the details of the notification processing. If an abnormality occurs in any of the power equipment 1 due to such notification processing, the fact is automatically notified to the security person. As a result, the security person can immediately move to the power equipment 1 in which the abnormality has occurred, and can perform inspection work, restoration work, and the like. Therefore, if an abnormality occurs in a certain power equipment 1, it is possible to notify the security person of the occurrence of the abnormality in the power equipment 1 and perform quick inspection and recovery work, etc. Regardless of this, it is said that a security guard patrols each electric power facility 1 regularly, or a security guard is stationed at each electric power facility 1. There is no need to perform troublesome and time-consuming operations. Also, if the receipt confirmation mail from the security officer in charge is not received, that is, it cannot be confirmed whether or not the notification to the security officer in charge has been made, or if the security officer is deemed unable to respond to the occurrence of the abnormality. In the case of an anomaly, a security agent is selected and notified of the occurrence of anomalies. Therefore, when an anomaly occurs, the danger of not being notified to any one of the security officers is reduced. Therefore, more reliable maintenance work can be performed. In addition, since the security person selected as a proxy in this way is in charge of the same area as the power equipment 1 in which the abnormality has occurred, it is highly likely that the security person can quickly move to the power equipment 1 and the Inspection and recovery process are more likely to be performed.

Further, in the remote monitoring center 6, when the transmission / reception unit 21 receives the abnormality information from any of the communication units 3, an e-mail is sent to the portable terminal 10 owned by the security guard by the above-described notification processing. At the same time as the transmission, the detailed abnormality information creating unit 23 performs abnormal detailed information creation processing. The details of the abnormality information detail creation processing are as described above, and the abnormality detail information including various types of information on monitoring of power equipment and the like can be accessed from the mobile terminal 10 by the abnormality detail information creation processing. Created by formula. Therefore, the security person can access the detailed abnormality information using the mobile terminal 10. That is, the security person who is the holder of the portable terminal 10 can refer to these detailed and latest information using the portable terminal 10. For example, a security person other than the person in charge of the power equipment in which the abnormality occurred (the above-mentioned surrogate security officer) receives an e-mail for notification of the occurrence of the abnormality and performs work such as inspection and restoration of the power equipment. In doing so, if detailed information on the power equipment can be used, inspection and restoration work can be performed efficiently. In addition, if information such as the address of each electric power facility, traffic access method, and surrounding map is included in such anomaly detailed information content, security personnel other than the responsible security officer can refer to and use this information. It can assist in moving quickly to the power equipment where the abnormality has occurred.

Further, as described above, when the abnormality information is received from any of the communication units 3, the remote monitoring center 6 performs the notification processing and the abnormality detailed information creation processing, while the communication is performed at predetermined intervals. When the monitoring result information transmitted from the unit 3 is received, the processing for creating the monitoring history information is performed by the history information creating unit 24 described above. You. The content of the process of creating the monitoring history information is as described above. With this process, the monitoring history information is edited by a predetermined document creation application, and the monitoring history information is converted into a document file of a predetermined format. Stored in the abnormal detail database 26. If the specified format is made to conform to the format stipulated in the Electricity Business Act as described above, the editing work can be performed on a personal computer or the like from which this document file has been downloaded, Can prepare documents for submission as required by the provisions of the above.

Incidentally, in the present embodiment, as described above, the transmission of the abnormality information and the monitoring history information from the communication unit 3 to the remote monitoring center 6 is performed by packet communication via the packet communication network 4. I have. This is for the following reasons. The abnormality information is information indicating the occurrence / recovery of an abnormality for a predetermined monitoring item, and the monitoring history information is data indicating the history of abnormality of each monitoring item within a predetermined period, and the data of each information. In general, the volume is significantly smaller than when voice or video communication is performed. Therefore, by adopting packet communication, when transmitting abnormal information and monitoring history information, communication between each communication unit 3 and the remote monitoring center 6 is performed using the general telephone network or the mobile telephone network. Data transmission can be performed more efficiently than when data is transmitted by occupying the line. In addition, since data transmission and reception between the remote monitoring center 6 and the mobile terminal 10 of each security person is also performed by packet communication via the packet communication network 8, similarly efficient data communication can be performed. it can.

Also, in the method of transmitting data by occupying the line, if a remote monitoring service is provided in which one remote monitoring center 6 communicates with a communication unit 3 corresponding to a number of power facilities 1, Considering that a large number of power facilities 1 may malfunction at almost the same time, it is necessary to prepare many lines at the remote monitoring center 6 side. On the other hand, by employing packet communication as in the present embodiment, it is possible to cope with a case where an abnormality occurs in many power facilities 1 at almost the same time without preparing a large number of lines. You can.

D. Variations
