Description

  The present invention relates to a remote monitoring system and a data transfer setting service providing method that collectively monitor information by using a communication network for facilities at bases distributed over a wide area.

  Due to the recent development of social communication infrastructure and the development of communication technology, information is being transmitted smoothly between remote business locations. Among them, companies and administrative organizations that have bases throughout the country use a wide-area IP (Internet Protocol) communication network owned by a telecommunications carrier as if they were connecting remote networks with a LAN. There are an increasing number of cases where a service for constructing a virtual private network (VPN) that can be used is used.

  Here, with the improvement of convenience, the amount of communication data flowing through the network also tends to increase, which is a factor that further increases the communication cost. For this reason, in addition to a method of reducing communication data by information communication technology such as data compression, a method of coping by examining the contents of communication data and the necessity of communication is being studied.

Further, in remote monitoring of a large number of buildings, a remote equipment monitoring device having a function of not making communication calls more than necessary by verifying the history of scheduled reports has been proposed (see Patent Document 1).
Furthermore, a network monitoring device has been proposed that reduces the amount of communication by changing the time interval of traffic monitoring according to a change in the traffic amount of the network (see Patent Document 2).
JP-A-8-47053 JP 2003-345682 A

  Many proposals for reducing the amount of network traffic have been made, as in the techniques described in Patent Documents 1 and 2 described above. However, when a remote monitoring system that collectively monitors a backbone network between business bases and a power supply facility in each business place is introduced for a plurality of business bases, the following problems occur.

  In other words, when using a backbone network, for example, various information systems manufactured by different manufacturers such as an in-house e-mail network, business system, production line system, equipment management system, etc. are based on industry standard protocols such as IP. A communication mode connected to a line is becoming common.

  However, the manager of the backbone network does not understand or understand the operation details of each information system described above. In addition, it is difficult to actively control the transmission priority of data transmitted from each of the information systems described above with respect to network traffic management. There was no effective means for leveling traffic.

  In addition, the administrator who maintains and operates each system is in a position to determine the priority between information that is issued from the information system that she manages and information that is issued from other information systems that are managed by others. It is common in operational management that it is not. For this reason, there is a tendency that data is transmitted from the information system even when data transmission is not urgent in time. That is, the operation management of these information systems has not contributed to the reduction or leveling of network traffic, or there has been no means for contributing to these information systems.

  In general, a backbone network based on the IP system is a constantly connected network using a communication device such as a router, and contracts for the communication speed of a communication service based on a transmission amount in a time zone in which network traffic is maximum. For this reason, it is desirable that the network traffic is leveled with respect to time series if possible.

  Therefore, the present invention aims to reduce the load of network traffic in a remote monitoring system for a power supply facility when a backbone network is introduced at a plurality of locations.

  In order to achieve the above object, the present invention provides a power facility equipped with a facility remote monitoring center for remotely monitoring a plurality of power facilities via a network to which a plurality of establishments equipped with power facilities are connected. A remote monitoring system, wherein each of the offices includes means for measuring a state of a power supply facility of the office, measurement data measured by the measuring means, operation information of the office, and equipment management information. Means for transmitting to the remote monitoring center, the facility remote monitoring center based on the measurement data, operation information, and facility management information of the power supply equipment of the office transmitted from each office. Means for determining the importance level for remotely monitoring the power supply equipment to be monitored, and obtaining the network usage rate from the network management center connected to the network Means for determining a data transfer setting criterion for information transmitted from the establishment from the network usage rate and the importance level; and means for transmitting the determined data transfer setting criterion to each establishment; This is a remote monitoring system for power supply equipment.

  Here, in a remote monitoring system that remotely monitors power supply facilities, network usage rates are acquired from a network management center that manages the network, and the network usage rates are classified and stored in a database. The processing device sets an importance level as a reference for data transfer setting, and determines the data transfer setting based on the facility management information and the network usage rate. The determined data transfer setting result is classified and stored in the database. The processing device remotely installs the data transfer setting in the facility monitoring control device at each business site.

  The system that remotely monitors the power equipment acquires the usage rate of the backbone network and determines the importance of transmission of the power equipment measurement values. Collect. Therefore, it is possible to reduce the amount of data communication due to the network usage rate or to reduce the maximum value in the time series of the network usage rate, the communication speed in the communication service contract can be lowered, and the cost can be reduced.

  ADVANTAGE OF THE INVENTION According to this invention, when most or all of the power supply equipment of a business base is controlled by remote monitoring, the measurement value data of a power supply equipment can be collected in the quiet time zone of network traffic. In general, when business bases are connected by a backbone network, the load of network traffic is expected to increase during hours of daytime such as daytime on weekdays. For this reason, according to the present invention, it is possible to contribute to load distribution and leveling over time series of network traffic.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 shows a system configuration example according to the present embodiment. The facility remote monitoring center 100 is provided with a processing device 10 such as a server for remotely monitoring the power supply facility 7 and the private power generation facility 6 for each office. Further, the facility remote monitoring center 100 includes a location database 12 for storing location information and facility configurations of all offices such as the A office 300, the B office 400, the C office 500, the D office 600, and the like. A private power generation fuel remaining amount database 13 is provided for storing the type information of the private power generation facility 6 installed in the office, the remaining amount of fuel, the operable time, and the operation state.

  Further, the facility remote monitoring center 100 has a fuel supply capacity database 14 for storing information on companies supplying fuel to the private power generation facilities 6 installed at the respective business offices A to D, and installed at the respective business offices A to D. Electricity storage that stores information on the reliability of power supply such as the number of power outage accidents at each of the offices A to D A supply reliability database 16, a network traffic database 17 that stores network traffic information of the wide area network 1, and a data transfer setting result database 18 that stores data transfer setting criteria and data transfer setting results are provided.

  The processing device 10 is connected to a wide area network 1 such as a public line or a dedicated communication line network via a communication device 9 such as a router or a modem. The processing device 10 is connected to an input / output terminal 11 such as a personal computer or a workstation for inputting data to the data transfer setting result database 18 or the like.

  For the facility remote monitoring center 100, devices and databases other than the network traffic database 17 and the data transfer setting result database 18 are the same as those in a conventional facility remote monitoring system.

  The network management center 200 has a network traffic database 20 for storing network traffic information of the wide area network 1, and the network traffic database 20 is connected to the wide area network 1 via a communication device 19 such as a router or a modem. The processing device 10 of the facility remote monitoring center 100 is connected to the wide area network 1 through the communication device 9, acquires the traffic information of the wide area network 1 from the network traffic database 20 through the communication device 19 of the network management center 200, and It can be stored in the traffic database 17.

  For example, in the office A 300, an input / output terminal 5 such as a personal computer or a workstation for inputting and browsing information in facility management, an in-house power generation facility 6 and a power supply facility 7, an operation state signal, a failure signal, a measurement Equipment monitoring and control devices 4 such as programmable logic controllers (sequencers) that acquire value signals and the like and input control signals such as start and stop are aggregated by a local network relay device 3 such as a network hub, and communicated by routers, modems, etc. It is connected to the wide area network 1 via the device 2.

  In addition, other information systems 8 in the office such as an in-house e-mail network, business system, production line system, etc. are also aggregated by the local network relay device 3 and connected to the wide area network 1 via the communication device 2. Is done. The processing device 10 of the facility remote monitoring center 100 communicates with the facility monitoring control device 4 via the communication device 9, the wide area network 1, the communication device 2, and the local network relay device 3, and the private power generation facility 6 and the power supply facility 7. Signal information is acquired and control signals are input. Further, the processing device 10 of the facility remote monitoring center 100 stores the information input from the input / output terminal 5 in the location database 12 or the like, and conversely outputs the information such as the self-generated fuel remaining amount database 13 to the input / output terminal 5. To do.

  In addition, what is necessary is just to comprise about the equipment monitoring control apparatus 4 and the input / output terminal 5 which were demonstrated above similarly to the conventional equipment remote monitoring system. Similarly to the A office 300, the B office 400, the C office 500, and the D office 600 are also provided with the equipment monitoring control device 4, the input / output terminal 5, and other information systems 8 in the office. ing.

  In the case of a facility that requires high reliability for a power supply facility, the number of measurement value acquisition points of the power supply facility of the private power generation facility 6 and the power supply facility 7 monitored by the facility monitoring control device 4 depends on the scale of the power supply facility. It is necessary to monitor information such as current value, voltage value and temperature in each part of the power supply equipment. For this reason, the number of measurement value acquisition points of the power supply facility often becomes several tens to several hundreds per power supply facility. In the case of a government-affiliated system, it is not uncommon to have business bases nationwide, so the total number of measurement value acquisition points may reach tens of thousands when performing remote 24-hour collective monitoring.

  Here, if the total number of measurement value acquisition points is 50,000, and one measurement value is expressed with an accuracy of 4 bytes, 50,000 × 4 = 200,000 bytes = about 0.2 megabytes. However, since information such as the business office, power supply equipment, measurement value acquisition point, etc. and IP communication, etc., address information of the communication device is actually added by several tens of bytes for each data frame, every second When performing real-time display for acquiring and updating information on power supply equipment, information of several tens to several hundreds of megabytes flows. Furthermore, in order to acquire the characteristics at the time of starting and stopping of the power supply equipment, it is necessary to acquire measurement values in units of 0.1 seconds, so the amount of data increases significantly.

  In the case of Internet communication based on the ADSL (Asymmetric Digital Subscriber Line) method and the like that has become widespread in recent years, the communication speed is several tens of megabytes per second and the usage fee is about several thousand yen per month in urban areas, which is relatively inexpensive. However, the Internet line is basically a best-effort type with no guarantee of communication speed, and since many unspecified terminals are connected, it is important for important facilities and businesses that require high line reliability. Tend not to be adopted.

  For this reason, a dedicated line will be introduced in the remote monitoring system for power equipment, but the dedicated line is a service with a communication speed of several megabytes per second even in urban areas, and the usage fee is about several hundred thousand yen per month. It is in. Therefore, as a service user, there is always a need for cost reduction by reducing the communication speed to be contracted by reducing the data flowing through the network or leveling the time series. Yes.

  In the case of this example, there is data generated by another information system 8 in the office such as an electronic mail network, a business system, a production line system, etc. other than the remote monitoring system of the power supply facility. For this reason, according to the necessity in facility operation, communication is performed avoiding the time zone in which other information systems 8 frequently transmit data, thereby contributing to leveling of network traffic with respect to time series.

Next, a network traffic congestion reducing method according to this embodiment will be described.
In FIG. 1, the facility management information input from the input / output terminal 5 of the office A 300 and the facility operation information, failure information, and measurement value information acquired by the facility monitoring control device 4 are processed by the facility remote monitoring center 100. Sent to the device 10. Then, the processing apparatus 10 stores the received information in the location value database 12, the self-generated fuel remaining amount database 13, the fuel supply capability database 14, the maintenance company database 15, and the power supply reliability database 16. Further, the processing device 10 calculates the expected operation time based on the fuel remaining amount and the fuel consumption rate of the private power generation facility 6 stored in the private power generation fuel remaining amount database 13, and calculates the calculation result as the private power generation fuel remaining amount database 13. To store.

  Further, the processing device 10 of the facility remote monitoring center 100 periodically acquires the traffic information of the wide area network 1 stored in the network traffic database 20 of the network management center 200, and the network traffic database 17 of the facility remote monitoring center 100. To store.

  The input / output terminal 11 of the facility remote monitoring center 100 monitors the facilities of each office (A to D) monitored by the facility remote monitoring center 100 based on information collected from each office (A to D). The priority order of importance and the data transfer time interval according to the priority order are set. When the data transfer setting standard for the data transfer time interval is formulated in the input / output terminal 11, the processing device 10 stores the formulated data transfer setting standard in the data transfer result database 18.

  Further, the processing device 10 of the facility remote monitoring center 100 includes facility information stored in a location value database 12, a private power generation fuel remaining amount database 13, a fuel supply capability database 14, a maintenance company database 15, and a power supply reliability database 16. The data transfer time for each power supply facility is set based on the network utilization rate information stored in the network traffic database 17 and the data transfer setting criteria stored in the data transfer setting result database 18, and the set power supply The data transfer time for each facility is stored in the data transfer result database 18.

  When the facility monitoring control device 4 of each office (A to D) has a function of transmitting measurement data to the remote facility management center 100 according to a schedule set in advance, the processing device 10 of the facility remote monitoring center 100 Updates the data transfer time for each power supply facility stored in the data transfer result database 18 based on the measurement data sent from each office. Then, when the data transfer time is updated in the processing device 10 of the facility remote monitoring center 100, the processing device 10 changes the setting in the facility monitoring control device 4 and changes the transmission time of the measurement data.

  In addition, the facility monitoring control device 4 may have a function of transmitting measurement data accumulated by the facility monitoring control device 4 in response to a data transmission request from the processing device 10 of the remote facility management center 100. In such a case, as a matter of course, the processing device 10 makes a data transmission request to the facility monitoring control device 4 of each office based on the data transfer time for each power supply facility stored in the data transfer result database 18. I do.

  FIG. 2 is a diagram showing an example of items and contents of information stored in the location value database 12. These pieces of information are stored in the facility remote monitoring center when the facility (for example, the plant A 300) is monitored by the facility remote monitoring center 100 or when the facility configuration of the plant A 300 is changed. 100 input / output terminals 11 or the input / output terminal 5 of the office A 300. The accumulation of such information is relatively common in a system for remotely monitoring and managing equipment.

  FIG. 3 is a diagram showing an example of items and contents of information stored in the private power generation fuel remaining amount database 13. Among these pieces of information, the establishment name, the type of private power generation equipment, and the fuel tank capacity, for example, when the establishment A 300 is monitored by the equipment remote monitoring center 100 or in the equipment configuration of the establishment A 300. When there is a change, it is input from the input / output terminal 11 of the facility remote monitoring center 100 or the input / output terminal 5 of the office.

  Further, the remaining amount of fuel and the operating state of the power generation facility are information acquired from the facility monitoring control device 4 of the A office 300. Further, the average fuel consumption rate during operation and the operable time are information calculated by the processing device 10 based on the remaining amount of fuel and the duration of the operating state of the power generation facility. The accumulation of such information is relatively common in systems that remotely monitor and manage equipment.

  FIG. 4 is a diagram showing an example of items and contents of information stored in the fuel supply capacity database 14. This information is obtained when the establishment (for example, A establishment 300) is monitored by the facility remote monitoring center 100, when the equipment configuration of the A establishment is changed, or the contractor of the A establishment. Is input from the input / output terminal 11 of the facility remote monitoring center 100 or the input / output terminal 5 of the A office 300, for example. The accumulation of such information is relatively common in a system that remotely monitors and manages equipment.

  FIG. 5 is a diagram showing an example of information items and contents stored in the maintenance company database 15. This information is available when the establishment (for example, A establishment 300) is monitored by the facility remote monitoring center 100, when the equipment configuration of the A establishment is changed, or the contractor of the A establishment changes. Or the like from the input / output terminal 11 of the facility remote monitoring center 100 or the input / output terminal 5 of the A office 300. Note that the accumulation of such information is also relatively common in systems that remotely monitor and manage equipment.

  FIG. 6 is a diagram illustrating an example of items and contents of information stored in the power supply reliability database 16. These pieces of information are input from the input / output terminal 11 of the facility remote monitoring center 100 or the input / output terminal 5 of the office A 300. Such information is also generally stored in a system for remotely monitoring and managing equipment.

  FIG. 7 is a diagram showing an example of information and item contents stored in the network traffic database 17. These pieces of information are acquired by the processing device 10 from the network traffic database 20 of the network management center 200 via the communication device 19, the wide area network 1, and the communication device 9, and stored in the network traffic database 17.

  FIG. 8 is a diagram illustrating an example of items and contents of information related to data transfer setting criteria among the information stored in the data transfer setting result database 18. In general, data transmitted and received by the equipment monitoring and control device 4 includes operating statuses such as starting and stopping of power equipment, equipment failures, operation instructions for equipment, current values, voltage values, temperatures, and other equipment measurement values at any location of the equipment. are categorized.

  Of these, the operational status, failure, and operation commands require immediate responsiveness in practice, and the frequency of data transmission / reception is less than that of facility measurement data that requires regular monitoring. It is normal. For this reason, in this embodiment, these operating states, failures, and operation commands are transmitted and received at any time when conditions occur. Needless to say, the need for acquisition of the facility measurement value changes depending on the maintenance environment based on the location of the establishment (for example, the establishment A 300).

  Specifically, in the case of business establishments such as urban areas, the necessity for monitoring is low because of the high reliability of the power supplied from the power company. Conversely, in remote islands and mountainous areas, the power situation is not as good as in urban areas, and there is a high possibility of being unattended at all times or unattended only at night. In addition, in remote islands and mountainous areas, there are many cases where there is no maintenance company in the vicinity, so it is necessary to improve the accuracy of remote monitoring. Therefore, in the example of FIG. 8, the importance level is set to 4 levels, the importance level 4 is once every 10 minutes, the importance level 3 is once every 4 hours, the importance level 2 is once every 24 hours, At the importance level 1, once (only) at the start of facility operation, the importance level can be selected and set from the input terminal 11 of the facility remote monitoring center 100 according to the necessity of monitoring.

FIG. 9 shows processing between each facility such as the facility remote monitoring center 100, the network management center 200, the A office 300, the B office 400, the C office 500, and the D office 600 regarding the data transfer setting of the equipment measurement values. It is the figure which showed an example of the flow.
In FIG. 9, for example, when the equipment configuration or the maintenance company is changed at the establishment (any one of A to D), the establishment name and its name are input from the input / output terminal 5 of the establishment. Change data regarding the facility is transmitted to the facility remote monitoring center 100 (step S901).

  The facility remote monitoring center 100 determines a regular period in which the network management center 200 can grasp the fluctuation of the network traffic in the office. Then, the facility remote monitoring center 100 makes a network traffic data acquisition request for each period (for example, one week) (step S902). In response to this request, the network management center 200 transfers information in the network traffic database 20 to the facility remote monitoring center 100 (step S903).

The facility remote monitoring center 100 stores the information of the network traffic database 20 transmitted from the network management center 200 in step S903 in the network traffic database 17 of the facility remote monitoring center 100.
In the facility remote monitoring center 100, the various facilities described above stored in the location value database 12, the privately generated fuel remaining amount database 13, the fuel supply capability database 14, the maintenance company database 15, the power supply reliability database 16, and the like. Based on the information, the traffic information stored in the network traffic database 17, and the data transfer setting criteria stored in the data transfer setting result database 18, the processing device 10 determines the transfer setting of the equipment measurement value data (step) S904). Then, the determination result of step S904 is stored in the data transfer setting result database 18.

  Further, as described above, the facility monitoring control device 4 of the business office (any business office of A to D) has a function of transmitting measurement data to the remote equipment management center 100 according to a schedule set in advance. In this case, the processing device 10 of the facility remote monitoring center 100 updates the data transfer setting for each power supply facility stored in the data transfer setting result database 18. If there is a change in the contents of the data transfer setting, the facility remote monitoring center 100 issues a remote installation request for data transfer setting to the facility monitoring control device 4 of the office (step S905).

  Upon receiving a remote installation request for data transfer setting from the facility remote monitoring center 100, the facility remote monitoring and control device 4 of the business office transmits a response to the remote installation request to the remote facility monitoring center 100 in response to the request (Step S4). S906). In response to the transmission of this response, the facility remote monitoring center 100 performs remote installation of data transfer settings for the facility monitoring control device 4 of the business office (step S907). The facility monitoring control device 4 of the business office transfers facility measurement value data to the facility remote monitoring center 100 based on the data transfer setting remotely installed in step S907 (step S908).

FIG. 10 is a diagram illustrating an example of a data transfer setting determination processing flow performed by the processing device 10 in the data transfer setting of facility measurement values. The importance levels shown in FIG. 10 are the four levels of importance shown in FIG.
In FIG. 10, the processing device 10 sets the initial value of the importance level of the facility to be determined to 1, and determines the importance level of the facility to be determined based on a preset threshold at this time. (Step S1001).

  Specifically, it is determined that the processing apparatus 10 needs attention in facility management such as the expected operation time stored in the facility remote monitoring center 100, the time required for refueling, the number of times of power outage accidents, and the time required for emergency dispatch. It is determined whether or not the importance level of the facility to be determined is appropriate based on a threshold set in advance for the information.

First, the processing apparatus 10 determines that it is appropriate to increment the importance level by +1 with respect to the initial value when the estimated operable time is lower than a preset threshold value. Subsequently, when the required time for refueling is higher than a preset threshold value, it is determined that it is appropriate to increment the importance level by +1 with respect to the initial value. Moreover, the processing apparatus 10 determines that it is appropriate to increment the importance level by +1 with respect to the initial value when the number of power outage accidents is higher than a preset threshold value. Subsequently, when the emergency required time is higher than a preset threshold value, it is determined that it is appropriate to set the importance level to +1 with respect to the initial value. Based on the determination, the importance level is reset.
The threshold value used for the determination in step S1001 is set by the input / output terminal 11 of the facility remote monitoring center 100 or the input / output terminal 5 of each office (A to D).

  Next, the processor 10 collects the measurement value collection time interval assigned to the importance level (any one of 1 to 4) that is the data transfer setting reference stored in the data transfer setting result database 18, the server, etc. Based on the current date and time held by the processing device 10 and the network usage rate stored in the network traffic database 17, the measured value collection scheduled time is set in the time zone with the lowest network usage rate (step S1002).

  Further, the processing device 10 determines whether or not the prediction of the network usage rate for the measurement value collection scheduled time set in step S1002 is equal to or greater than a preset threshold (step S1003). If it is determined in the determination step S1003 that the estimated network usage rate of the measurement value collection scheduled time is greater than or equal to a preset threshold value, the processing apparatus 10 sets the importance level to the current value − The value is rounded down by 1 and the measurement value collection scheduled time is reset again (step S1004).

  In the present embodiment, when the importance level is 4, the equipment measurement value data is acquired once every 10 minutes, and the measurement value is obtained from the network traffic acquisition time interval for which statistics are performed every two hours. Since the acquisition time interval is small, that is, the number of acquired data increases, the processing apparatus 10 acquires the measurement value every 10 minutes regardless of network traffic.

  FIG. 11 is a diagram illustrating an example of the contents of the data transfer setting result for each power supply facility of each office (A to D) stored in the data transfer setting result database 18. These pieces of information are determined by the processing apparatus 10 based on the information stored in each database of the facility remote monitoring center 100 and the determination criteria, and the determination result is stored in the data transfer setting result database 18. Is.

  FIG. 12 is a diagram showing an example of a data transfer setting service providing method using the facility remote monitoring center 100. Note that the data transfer setting service providing method shown in FIG. 12 is an example in which the facility remote monitoring center 100 undertakes remote monitoring of the power supply facilities of each office, and the communication fee is borne by each office. This example shows a service providing method in which the facility remote monitoring center 100 reduces the load of network traffic by setting data transfer.

  In FIG. 12, when each business establishment wishes to update the equipment measurement value data transfer setting, each business establishment transmits a service contract application to the equipment remote monitoring center 100 (step S1201). The facility remote monitoring center 100 receives a contract application from each business office, and transmits a response of contract approval to the office (step S1202).

  Each office transmits data on the name of each business establishment and its power supply equipment to the equipment remote monitoring center 100 (step S1203). Note that if the facility remote monitoring center 100 has already acquired the information in step S1203 in performing the power facility remote monitoring operation, the processing in step S1203 is omitted.

The facility remote monitoring center 100 requests network traffic data from the network management center 200 (step S1204), and receives and acquires transfer of network traffic data from the network management center 200 (step S1205).
In addition, the facility remote monitoring center 100 performs remote installation of data transfer settings to the facility monitoring control device 4 of each office (step S1206). Each office pays the equipment remote monitoring center 100 for providing the data transfer setting service (step S1207).

As described above, in the present embodiment, when the facility remote monitoring center 100 is connected to a plurality of information systems in many offices (A to D, etc.) using a wide area network, a wide area The maximum value of traffic with respect to the time series of the network can be avoided. As a result, fluctuations in network traffic over time can be reduced, the communication speed of communication services contracted by each office can be kept low, and the cost of communication charges can be reduced.
Needless to say, the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the gist of the present invention.
