DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a building, a road,
The present invention relates to a facility monitoring system for monitoring the occurrence of a failure in a facility installed on a railway or the like, and particularly to a facility monitoring system having a function of extracting an affected facility related to the failure from various information at the time of the failure.

[0002]

2. Description of the Related Art Conventionally, operating status information and status change information of a plurality of facilities such as electric power facilities and communication facilities have been collected.
Equipment monitoring systems 10 that are centrally managed by a single monitoring center are used in various industries. Equipment monitoring system 1
In the case of 0, not only the notification of the failure of the equipment that occurred, but also the recovery of the failure at an early stage, based on the failure information, the information of the equipment considered to be faulty or related equipment considered to be affected We are extracting.

FIG. 9 is a schematic diagram showing the configuration of the equipment monitoring system 10. As shown in FIG. As shown, the equipment monitoring system 1
Numeral 0 denotes a monitoring target facility 11, which is a facility / apparatus to be monitored, a monitoring information collecting apparatus 12 for collecting data for each information type / system, and a facility monitoring central apparatus 13 for centrally managing the state of the monitoring facility. Be composed. The monitoring target facility 11 includes a plurality of subordinate facilities 14 and a monitoring slave station 15 that collects some information generated from the subordinate facilities 14. For example, in a road monitoring system, the subordinate equipment 14 disposed at a key point on the road includes a substation equipment and a communication equipment, and more specifically, a storage battery, a fuse, a detector, an emergency telephone, a guidance display board, and the like.

The information issued from the lower-level equipment 14 includes so-called alarm information such as power supply abnormality, fuse cut, voltage drop abnormality, display board data transmission abnormality, etc., other equipment state change information, and equipment information. There is information such as equipment information to be specified. The various information collected by the monitoring slave station 15 is classified for each information system and transmitted to the monitoring information collection device 12 located in a monitoring center or the like. Further, the monitoring information collection device 12 performs necessary processing on the transmitted various information, generates a code indicating the location, name, failure type, occurrence time, etc. of the generated equipment and transmits the generated code to the equipment monitoring central device 13. I do.

FIG. 10 shows the relationship between the configuration of the conventional equipment monitoring central unit 13 and the flow of processing. The equipment monitoring central unit 13 classifies and sorts the information transmitted from the monitoring target equipment 11 via the monitoring information collection unit 12 ("alarm collection" (S01)), and waits for a certain period of time (for example, “Consolidation of state change information” (S02), which continues monitoring for 30 seconds), and “failure / operation determination” that determines whether the transmitted alarm information is due to a failure.
(S03), and the respective processes of “determining the cause equipment / affected equipment” (S04) for determining the equipment or the affected equipment that caused the failure information in this order, and displaying necessary information on the monitor display. (S05). Here, the information collected by monitoring in the “state change information collection” (S02) is stored in the broadcast collection database 131. Also, "failure / driving judgment"
The address facility correspondence database 132 used in (S03) previously stores, for each alarm information, information for distinguishing whether the alarm information is failure information or operation information.

Here, "determination of cause / affected facilities" (S
When the processing of 04) is executed, usually, a search of the equipment system database 133 is performed. The equipment system database 133 stores each lower equipment 14 and alarm information or the like issued from the equipment in a one-to-one correspondence, and further stores a physical configuration of the equipment, that is, a connection relation between the equipments. Things. When actually constructing the equipment, such a database is created in advance because the physical configuration and connection relationship of the lower equipment 14 and alarm information generated from the lower equipment 14 are determined in advance. be able to.

For example, in the facility system database 133, for the "storage battery" which is one of the substation facilities, "load voltage drop", "up transmission error", "liquid level drop" are determined in advance.
Are stored in association with each other. Also,
The substation equipment includes a "detector", a "transmission cable", a "storage battery", a "fuse", and the like, and stores that there is a connection relationship between the "storage battery" and the "fuse". In the process of the above “determination of the cause equipment / affected equipment” (S04), based on the transmitted alarm information, the equipment associated with the information is searched for, and the searched equipment is also determined. At that time, a search was made for the equipment associated with the equipment. That is, by searching all the data included in the equipment system database 133, the cause equipment and the affected equipment related to the alarm information are extracted.

[0008]

However, it takes a lot of time to search the equipment system database 133 having such a structure and find out the cause equipment and the affected equipment. For example, in the above-described road monitoring system, the equipment monitoring central unit 13 uses tens of thousands of
And the alarm information thereof are stored in the equipment system database 133 in association with each other. Therefore, as the number of monitoring points increases, the equipment configuration becomes more complicated, and the search becomes more difficult.

[0009] In such a large number of monitoring facilities, if only one alarm information is generated, it is relatively easy to retrieve the information. A lot of alarm information is generated with an arbitrary time lag. When such a large amount of alarm information is generated, it takes a considerably long time from the viewpoint of safety and disaster prevention of several minutes to several tens of minutes for the search itself, the judgment of the causative equipment and the judgment of the affected equipment. Was. In the case of a serious failure, it is necessary to take measures such as stopping the operation of the related facilities and notifying the related persons of the occurrence of the failure accurately and promptly, and the facility monitoring system 1 which requires a quick response.
The use of the monitoring system as described above for 0 was inappropriate in terms of safety.

[0010] The present invention has been made in view of the above points, and by introducing a priority order and a list structure into the storage of alarm information and related equipment, a large number of alarm information that has occurred can be obtained. On the other hand, the present invention provides a facility monitoring system capable of determining a cause facility and an affected facility as quickly as possible. Further, there is provided an equipment monitoring system capable of detecting occurrence of a failure of a logical contact which is equipment which does not automatically generate an alarm.

[0011]

SUMMARY OF THE INVENTION According to the present invention, in a facility monitoring system for monitoring the occurrence of a fault in a plurality of facilities, a plurality of pieces of alarm information issued from each facility are hierarchically prioritized and stored in a tree structure. Alarm hierarchy storage unit
Using an alarm list storage unit that stores alarm information related to any alarm information A and each facility related to the alarm information A in a list structure for each alarm information A, and the generated alarm information, It is an object of the present invention to provide a facility monitoring system including a facility extracting section that extracts an affected facility related to alarm information generated by searching an alarm hierarchy storage section and an alarm list storage section.

Here, the alarm hierarchy storage unit stores arbitrary alarm information A as having a higher priority, and one or a plurality of alarm information A which may be generated simultaneously when the alarm information A is generated. It is preferable to store the pieces of alarm information as having the next level of priority to the alarm information A.

The contents of the alarm information related to the arbitrary alarm information A stored in the alarm list storage unit may include N which has the next highest priority to the alarm information A stored in the alarm hierarchy storage unit. The number of pieces of alarm information (N ≧ 1) may be the head address of a list structure in which N pieces of alarm information are stored.

[0014] Further, the equipment extracting unit selects the alarm information from the generated alarm information in descending order of priority stored in the alarm hierarchy storage unit, and the alarm information stored in the alarm list storage unit. A search unit for searching the list structure of the alarm information, and a reading unit for reading out monitoring equipment included in the searched list structure as affected equipment may be provided.

[0015] Further, the equipment extraction unit may include the affected equipment,
The cause equipment that directly caused the generated alarm information and the affected equipment that may be affected by the generated alarm information may be separately extracted.

It is preferable to use a large-capacity hard disk such as a magnetic disk or an optical disk for the alarm hierarchy storage unit and the alarm list storage unit. It is desirable that the alarm information stored in the alarm hierarchy storage unit be stored together with a number indicating a priority. For example, the alarm information having the highest priority has priority 1 and n
The alarm information located at the third level stores the priority as n.

The alarm list storage unit stores all alarm information included in the equipment monitoring system.
These pieces of alarm information are stored in association with each other in a list structure. A pointer, that is, a head address of an area in which alarm information is stored can be used as an element for associating with each other.

The contents of one piece of alarm information stored in the alarm list storage unit include, in addition to the identification information of the alarm information, the head of an area in which alarm information having a priority immediately below the alarm information is stored. The address and the information on the affected equipment related to the alarm information are included.
Here, the affected equipment can be classified into two, the causal equipment and the affected equipment, as described above. In the state where such classification has been performed in advance, the alarm information is stored in the list structure of each alarm information in the alarm list storage unit. It is preferable to memorize it.

The present invention also stores, for each logical contact, a logical contact extraction list in which logical contacts, which are facilities that do not autonomously generate alarms, are associated with facilities that are affected by the failure of the logical contact. The logical contact storage unit is searched using the generated logical contact storage unit and the generated alarm information, and the logical contact extraction list including the equipment that generated the alarm is selected, and the alarm of the logical contact included in the logical contact extraction list is selected. An equipment monitoring system further provided with a logical contact determination unit for creating information.

Here, the "logical contact" refers to a facility / equipment that does not autonomously generate an alarm, for example, a collective cable. On the other hand, equipment that can automatically generate an alarm is called a “physical contact”. Whether a logical contact has failed or not is determined by whether an alarm issued from a physical contact affected by the failure of the logical contact satisfies a certain condition. For example, for a logical contact to which multiple physical contacts are connected, if an alarm occurs from all these physical contacts,
It is logically determined that a failure has occurred in this logical contact.

As the logical contact storage unit, a hard disk or an optical disk is used similarly to the alarm list storage unit. The logical contact extraction list is data in which "logical contacts" are associated with "equipment affected by the failure of this logical contact". For example, a logical contact and a plurality of logical contacts physically connected to the logical contact This is data that is associated with physical contacts.

Specifically, when a collective cable connected to N vehicle detectors is treated as a logical contact, a logical issue (collective cable) and N physical contacts (vehicle detector)
Are stored in association with each other in a list structure. The logical contact determination unit performs search and selection of the stored list and creation of alarm information.
It can be realized by a microcomputer including an OM, a RAM, a timer, and the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings. Note that the present invention is not limited to this. In the present invention, based on the alarm information that has occurred, when determining the cause equipment and the affected equipment, when each alarm information hierarchically prioritized "alarm configuration diagram", for each alarm information, Use the "alarm list" stored in association with related equipment.

First Embodiment FIG. 1 is a diagram showing the relationship between the configuration of the equipment monitoring central unit 13 of the present invention and the flow of processing. The present invention searches for an "alarm configuration diagram" and an "alarm list" as shown below, instead of the conventional equipment system database 133 shown in FIG. 10, thereby determining the cause equipment and the affected equipment (S04). ') Speeding up. The equipment monitoring system according to the present invention may have the same configuration as the equipment monitoring system 10 shown in FIG. Hereinafter, specific examples of the configuration of the “alarm configuration diagram” and the “alarm list” will be described.

First, FIG. 2 shows a configuration example of equipment to be monitored as an embodiment of the present invention. Here, the equipment to be monitored corresponds to the lower-level equipment 14 shown in FIG. 9, and the collection devices 1 and 2 that collect various data, and the data received by the collection devices 1 and 2 receive a predetermined number of data. Of processing units 1 and 2 for performing the above processing. It is assumed that the processing device 1 and the processing device 2 are connected by an optical cable. Further, it is assumed that power is supplied to the collection devices 1 and 2 from the processing devices 1 and 2, respectively. like this,
The alarm information output from the monitoring system composed of the four subordinate equipments 14 is collected in the monitoring slave station 15 and further transmitted to the equipment monitoring central unit 13 via the same route as shown in FIG.

FIG. 3 is a diagram showing the relationship between each monitoring facility shown in FIG. 2 and alarm information output from the monitoring facility. In FIG. 3, for example, from the processing apparatus 1, “power-off A
1, “connected device error A2”, and “communication card error A3” are output, and the collection device 2 outputs “power off E1”, “transmission error E2”, And that three pieces of alarm information of “reception abnormality E3” are output. The correspondence between these monitoring equipment and the output alarm information should be determined in advance when the system is constructed.

In the following description, for convenience, the processing device 1 is "A", the processing device 2 is "B", the optical cable is "C", the collection device 1 is "D", and the collection device 2 is "E".
It shall be represented by the equipment code. The monitoring equipment is generally managed by being provided with the equipment codes (A to E) as described above. The following hierarchical alarm configuration diagram is created using the correlation diagram between FIG. 3 and each alarm information. The alarm configuration diagram is created by the supervisor in charge of the equipment monitoring central unit 13, and the equipment monitoring central unit 1
3 is stored in a storage device, for example, a hard disk such as a magnetic disk or an optical disk.

FIGS. 4 and 5 show alarm configuration diagrams described in a tree structure corresponding to the monitoring equipment shown in FIG. Here, the alarm configuration diagram shows the prioritization of alarm information,
That is, the alarm information is created by associating each alarm information with the hierarchy and associating the alarm information with the equipment (causing equipment) or the equipment affected (influenced equipment) that causes the occurrence of certain alarm information. When the alarm information is prioritized, a priority number is stored in association with each alarm information. When the cause equipment or the affected equipment is associated, the identification code of the cause equipment or the affected equipment is stored in association with the alarm information.

For example, in FIG.
3 (reception abnormality of the collection device 1 (D)), when this occurs, alarm information D1 (power cutoff of the collection device 1 (D)) may also occur, and furthermore, the alarm information D2
(Transmission abnormalities of the collection device 1 (D)) may also occur, so that the alarm information D1 and D2 are arranged in the next level hierarchy of the alarm information D3. Alarm information D
3 is "1", the alarm information D1, D2
Has a priority of “2”. Further, since the direct equipment that causes the generation of the alarm information D3 is the collection device 1 (D), the alarm information D3 is associated with the equipment code D.
In FIG. 4, parentheses are given in the meaning of the direct cause equipment to indicate (D), and are distinguished from the affected equipment without parentheses.

Similarly, when alarm information D1 is generated, alarm information A1 may be generated.
Can be associated with the identification code D (collection device 1). The cause of the direct occurrence of the alarm information A1 (power interruption) is the equipment A (processing apparatus 1), but since the power is supplied from the processing apparatus 1 to the collection apparatus 1, the alarm information A1 is generated. This is likely to affect the facility D (collection device 1). In this sense, in FIG. 4, the alarm equipment A1 is associated with the cause equipment (A) and the influence equipment D.

Similarly, alarm information A1 and A3 are hierarchically related to alarm information D2, and cause equipment (D) is further associated therewith. The alarm information A1 and A3 are associated with the equipment (A) as the equipment causing both and the equipment D as the affected equipment.

Further, in the alarm configuration diagram of FIG.
When the alarm information of the quality deterioration C2 of the optical cable is generated, the priority is assigned as shown in FIG. 5 in the sense that the line disconnection C1 and the connection device abnormalities A2 and B2 may occur. In FIG. 5, alarm information A
The equipment directly responsible for 2 (connection device error) is equipment (A)
Indicates that the affected facility is facility C (optical cable), the facility that directly causes alarm information B1 (power cutoff) is facility (B), and the affected facility is facility E (collection device 2). It indicates that there is.

FIGS. 6 and 7 show specific examples of the alarm list used in the present invention. This alarm list expresses the relation between the pieces of alarm information and the relation between the cause equipment or the affected equipment corresponding to the alarm information in a so-called list structure.

FIG. 6 corresponds to the alarm configuration diagram shown in FIG. 4, and FIG. 7 corresponds to the alarm configuration diagram shown in FIG. In FIG. 6, for example, the list structure for alarm information D1 is followed by alarm information A1, and the fact that the cause equipment is equipment (D) is stored. The list structure for the alarm information D3 is followed by the alarm information D1 and D2, and the fact that the cause facility is the facility (D) is stored. The list structure for the alarm information A3 includes the cause facility (A), and the fact that the affected facility is the facility D is stored. Similarly, the connection relationship between the alarm information and the monitoring equipment is stored in FIG.

Specifically, the list structure of each alarm information is stored in a predetermined storage area in the hard disk for each alarm information. The connection relation of each list structure can be indicated by the head address of the storage area of the following alarm information. That is, in the list structure of a certain alarm information, the head address of the storage area of the alarm information hierarchically related as shown in the alarm configuration diagram, the identification code of the cause equipment and the identification code of the affected equipment are stored. Is done. As described above, by storing the list structure, it is necessary to input the relationship between the alarm information and the monitoring equipment, but it is not necessary to input the information on the connection relation between complicated equipment.

Incidentally, this list structure is also generated on a storage device in the equipment monitoring central unit 13, for example, a hard disk such as a magnetic hard disk or an optical disk. Generally, the equipment monitoring central unit 13 includes a CPU, ROM, RA
M, and a microcomputer including an I / O controller and a timer, and a storage device, a display device, a communication device, and an input device.
It is executed by a control program stored in M or the like.
The above-mentioned list structure may be input directly from the input device by the person in charge of monitoring, or may be automatically created from the above-mentioned alarm configuration diagram by a control program.

The alarm configuration diagram and the alarm list used to determine the cause equipment and the affected equipment have been described above. These are shown before the actual operation of the system or when the new equipment is introduced and the operation is actually started. Must be created beforehand.

Next, using the alarm configuration diagram and the alarm list, processing for determining the cause equipment and the affected equipment (S0)
4 ') will be described. The cause facility / affected facility determination process (S04 ') is executed by repeating the following four processes. 1) Prioritize the alarm information obtained from the failure / operation determination processing (S03) using the alarm configuration diagram. That is, an alarm information occurrence list arranged in descending order of priority is created. 2) The alarm information having the highest priority is selected from the alarm information occurrence list, and the alarm information existing in the occurrence list among the connection-related alarm information is searched using the alarm list. At the time of this search, the equipment identification code stored in each list structure of the alarm list is extracted into a predetermined storage area.

3) During the execution of the search, if the next alarm list to be searched reaches an alarm list (for example, the A1 list in FIG. 6), the search is interrupted, and the searched alarm information is Delete from the alarm information occurrence list created in 1) above. 4) Identify the cause equipment and the affected equipment from the equipment identification codes extracted by the search. Here, the causal equipment stored in the retrieved alarm information of the lowest layer is determined as the causal equipment for the retrieved series of alarm information, and all other extracted equipments are determined as the affected equipment. Such processing is repeated, and when there is no more alarm information in the alarm information occurrence list, the determination processing ends.

Hereinafter, specific examples of these processes will be described. For example, assuming that only the alarm information D3 has occurred, the alarm list corresponding to the alarm information D3 is searched by the above process 2). The alarm information occurrence list includes only the alarm information D3. The alarm list D3 shown in FIG. 6 includes alarm information D1 and D1.
Although the head address to the alarm list of No. 2 is indicated, the search is interrupted here because neither of the alarm information D1 and D2 is included in the occurrence list, and the cause equipment stored in the alarm list of D3 (D) is extracted.

Assuming that alarm information D3 and D2 have occurred, first, D3 having a higher priority is selected, and D3 is selected.
The alarm list is searched in the order of the alarm list No. 3 and then the alarm list D2. Then, the search is interrupted here, and the cause equipment (D) in the alarm list of D2 is extracted.

Similarly, when three alarms D3, D2, and A1 occur, the alarm list is searched in the order of D3, D2, and A1, and the alarm list of A1 is searched. The equipment (A) stored in the alarm list of A1 is extracted as the cause equipment, and the equipment D is extracted as the affected equipment.

Next, specific examples of the alarm configuration diagrams and the alarm list shown in FIGS. 5 and 7 will be described. When only the alarm information C2 occurs, only the alarm list of C2 is searched, and the equipment (C) is extracted as the cause equipment. When alarm information C2 and B2 occur, C2,
The alarm list is searched in the order of B2, and equipment (B) is extracted as the cause equipment and equipment C is extracted as the affected equipment. If alarms C2, A2 and A1 occur, C2, A
2. The alarm list is searched in the order of A1, and the equipment (A) is extracted as the cause equipment, and the equipment D in the alarm list of A1 and the equipment C in the alarm list of A2 are extracted as the affected equipment.

After the completion of the judgment processing, the alarm information and the equipment causing the alarm and the equipment affected by the alarm information are displayed in an appropriate manner using images, voices, characters, etc. in order to notify the judgment result to the person in charge of monitoring. What should I do? 1) to 4) above
Among the processes shown in (1), the process of creating an "alarm information occurrence list" in which generated alarm information is arranged in the order of higher priority and the process of searching the alarm list are the processes that are the features of the present invention. Here, since the alarm information generated in advance is hierarchically classified according to the alarm configuration diagram, it is possible to prioritize the alarm information in a short time. further,
Since the alarm lists are linked in a so-called list structure, a search for a series of alarm information ends only by following the list structure by the number of generated alarm information.

That is, when the correlation between the monitoring equipment and the alarm information and the connection between the monitoring equipment are stored in a database and stored, it is necessary to search all the databases for every alarm information generated. On the other hand, in the processes 1) to 4) described above, a slight search is required. Therefore, by using the alarm configuration diagram and the alarm list as described above, it is possible to greatly reduce the time required for the process of determining the cause equipment and the affected equipment.

FIG. 8 shows another embodiment of the alarm list of the present invention. FIG. 8A shows a specific example of alarm information and monitoring equipment in the road equipment control system, and FIG. 8B shows a specific example of these alarm lists. Also in this case, the cause equipment and the affected equipment can be determined by searching the alarm list based on the generated alarm information.

Second Embodiment An embodiment for detecting a failure of a logical contact, which is equipment that does not automatically generate an alarm, will be described below. By detecting such a failure of the logical contact, the efficiency of the failure isolation work conventionally performed by the operator's labor and experience can be improved, and the time from the occurrence of the failure to the recovery can be shortened.

FIG. 11 is a diagram showing the relationship between the configuration of the equipment monitoring central unit and the processing flow in the second embodiment. FIG. 11 differs from FIG.
Is newly provided, and “logical contact determination processing” S06 is newly added. "Logical contact determination processing" S
In step 06, the logical contact monitoring database 13 is created using the alarm information collected in the broadcast aggregation database 131.
6, a process of extracting a logical contact to be set as an alarm, adding alarm information about the logical contact to the broadcast aggregation database 131, and the like are performed.

That is, by using the alarm information collected from the equipment that automatically generates an alarm, it is determined whether or not there is an alarm at a logical contact that cannot automatically generate an alarm. create. As a result, a logical contact that has not been able to take in an alarm autonomously until now can be detected as one piece of alarm information when a failure occurs.

FIG. 12 is a block diagram of specific equipment used for explaining the second embodiment. Here, a configuration of a part of equipment used in a traffic control system of a highway is shown. The vehicle detectors A to K are, for example, ultrasonic sensors that detect that the vehicle has passed. The electric signals detected by these vehicle detectors are divided into two systems and transferred to the collective vehicle detection devices # 1 and # 2 through the collective cables # 1 and # 2, respectively. Then, the collective vehicle detection devices # 1 and # 2 process the detected electric signals, add necessary information such as position information, and transfer the processed signals to the traffic control preprocessing device F. In the traffic control pre-processing device F,
The collected information is transferred to a higher-level traffic control device.

Of the equipment shown in FIG. 12, all of the equipment except for the collective cables # 1 and # 2 are "physical contacts" capable of autonomously generating an alarm. It can be transferred to a traffic control device. Detecting a failure or the like by detecting a state in which the “physical contact” cannot transfer information to a higher-level position by a higher-level device also corresponds to autonomously generating an alarm.

FIG. 13 is a diagram showing the relationship between the equipment shown in FIG. 12 and the alarm information. For example, the vehicle detector # 01 can autonomously generate an alarm of "detector failure", and the collective vehicle detection device # 2 can autonomously generate an alarm of "data error".
Also, the collective cables # 1 and # 2 are “logical contacts”,
Although an alarm is not issued autonomously, an alarm from a cable disconnection is issued by an alarm from another autonomous facility.

In FIG. 13, a to m denote equipment identification codes used in the alarm list, and A to M denote alarm information corresponding to each equipment. Next, a description will be given of the logical configuration of the “collective cable” that is a logical contact and the “vehicle detector” that is a physical contact. In the specific example of FIG. 12, all the information from the vehicle detectors # 01, # 02, # 03, and # 04 flows on the collective cable # 1.

The collective vehicle detection device # 1 is provided with a vehicle detector #
If information cannot be received from all of the vehicles 01, # 02, # 03, and # 04, it is possible that all four vehicle detectors have failed, but all four vehicle detectors have failed simultaneously. Is considered to be very infrequent.
In such a case, it is natural to consider that the collective cable # 1 is disconnected, and the disconnection of the collective cable often occurs in actual circumstances. Therefore, four pieces of alarm information (A,
(B, C, D) to the operator, it is more likely that the alarm information G indicating that the collective cable is disconnected is shown to the operator more accurately and promptly for the failure.

Therefore, the vehicle detectors # 01, # 02, # 0
When all the alarm information (A, B, C, D) from # 3 and # 04 has occurred, it is determined that the alarm G indicating that "the collective cable # 1 is disconnected" has occurred. . Similarly, vehicle detectors # 11, # 12, # 13, #
If all the alarm information (H, I, J, K) from 14 has been generated, it is determined that the alarm M indicating that "the collective cable # 2 is disconnected" is generated.

When it is determined that "the collective cable # 1 is disconnected", the alarm information G of the collective cable, which is a logical contact, is added to the broadcast aggregation database 131, and further, the collective cable The four pieces of alarm information (A, B, C, D) for which it has been determined that the # 1 alarm has occurred are deleted. As described above, the alarm information of the logical contact that does not automatically generate an alarm is created in the broadcast aggregation database 131 storing the alarm occurrence list.

FIG. 14 shows the second example shown in FIG. 12 and FIG.
FIG. 3 shows an alarm configuration diagram in the embodiment. This is an alarm configuration diagram when there are logical contacts G and M. The collective vehicle detection devices E and L and the vehicle detectors A, B, C, D, H, and
Logical contacts (collective cable) are located between I, J and K. When the alarm G of the logical contact occurs in FIG. 14, the cause equipment is the collective cable # 1 (g) and the affected equipment is the vehicle detectors # 01 to # 04 (a, b, c, d). Is shown. If no logical contact is provided, there are no G and M, so the vehicle detectors A, B, C, D, H, I, J, and K are located immediately below the collective vehicle detection devices E and L. .

FIG. 15 is an alarm list corresponding to the alarm configuration diagram of FIG. Here, the left sides of the arrows in the F, E, and G alarm lists 51, 52, and 53 indicate the alarms of the upper-level equipment, and the right sides of the arrows indicate the alarms of the corresponding lower-level equipment. In the alarm lists 51, 52, and 53 of F, E, and G, symbols (f), (e), and (g) in parentheses indicate cause equipment, and lowercase letters without parentheses indicate affected equipment. I have.

For example, the alarm list 53 of the alarm information G of the logical contact includes the alarm list A,
Regarding B, C, D (54-57), if there is no alarm of lower-level equipment, the cause and effect are (g), that is, the aggregate cable # 1, and the affected equipment is a, b, c, d, The four vehicle detectors # 01, # 02, # 03, and # 04 are shown. The alarm list 51 of F and the alarm list 52 of E include a logical contact g (collective cable # 1) as an affected facility.

FIG. 16 is an alarm list when it is considered that there are no logical contacts G and M in the alarm configuration diagram of FIG. Here, since there is no logical contact G, the alarm list 62 of E is directly related to the alarm lists A, B, C, and D (54 to 57) of the vehicle detector which is the lower-level equipment,
This indicates that the cause equipment is (e) and the affected equipment is a, b, c, and d. Also, the alarm list 61 of F
There is no collective cable g in the affected equipment.

FIG. 17 is a logical contact point extraction list corresponding to the alarm configuration diagram shown in FIG. This logical contact extraction list is stored in the logical contact monitoring database 136 in advance. For example, the G logical contact point extraction list 71 indicates that alarm information G has occurred when all of the alarm information A, B, C, and D have occurred. This list is used to determine whether or not an alarm has occurred at a logical contact based on the alarm information in the broadcast aggregation database 131.

Next, the logical contact determination processing S shown in FIG.
06 will be described. FIG. 18 is an explanatory diagram of a change in alarm information that has occurred at the time of logical contact determination. The generated alarm information is stored in the broadcast aggregation database 131 by the state change information aggregation processing S02. Now, as shown in "Occurrence alarm information before logical contact determination" 81 in FIG. 18, five pieces of alarm information A, B, C,
It is assumed that D and F have occurred. The logical contact monitoring database 136 includes the logical contact extraction list 7 shown in FIG.
It is assumed that 1, 72 are stored in advance.

After the status change information aggregation process S02, in the logical contact determination process S06, first, the logical contact monitoring database 136 is searched. In this search processing, all the alarm elements appearing on the left side of the logical contact extraction list are selected from the logical contact extraction list included in the “alarm information before logical contact judgment” 81. That is,
"Occurrence alarm information before logical contact determination" 81 includes A,
Since all of B, C, and D are included, the G logical contact extraction list 71 is selected.

Next, a process is performed in which the four alarm information items A, B, C, and D that are currently occurring are replaced with the logical contact alarm information G appearing on the right side of the selected logical contact extraction list. Specifically, the broadcast aggregation database 131
, The alarm information A, B, C, and D are deleted, and the alarm information G of the logical contact is added.

With the above processing, as shown in "Occurrence alarm information after logical contact determination" 82, a logical contact that cannot automatically generate an alarm can be raised as an alarm. As described above, the logical contact determination means S0
In step 6, after the "generated alarm information after logical contact determination" 82 is created, the cause / effect facility is specified in the cause / effect facility determination process S04 'through the failure / operation determination process S03.

FIG. 19 is an explanatory diagram of the determination results of the cause equipment and the affected equipment. Alarm information generated after logical contact judgment 8
2, since “G” exists, the G alarm list 53 is extracted from the alarm list 135. Further, the generated alarm information 82 after the logical contact determination includes A, B, C,
Since D does not exist, “(g)” in the alarm list of G, that is, the collective cable # 1, becomes the cause equipment, and “a, b, c, d”, that is, the vehicle detector # 01,
# 02, # 03, and # 04 are identified as affected facilities.

By introducing the logical contact determination processing as described above, more accurate and quick failure recovery and maintenance work can be performed.

[0068]

According to the present invention, alarm information is prioritized and stored in a tree structure, and the alarm equipment and the monitoring equipment related to the alarm information are stored in a list structure. Even if information occurs,
The affected equipment can be quickly extracted. Therefore, in equipment monitoring systems that require high responsiveness,
Quick and accurate failure recovery work can be performed. In addition, it is possible to autonomously detect a failure of a facility that does not generate an alarm, and it is possible to increase the efficiency of the work of isolating the failure and shorten the time from occurrence of the failure to recovery.
