Description

  The present invention relates to a technique for issuing an alarm when a moving body such as a person or heavy equipment approaches a target facility more than a certain degree, and in particular, an alarm device, an alarm system, and an alarm computer suitable for use in facilities such as a substation Regarding the program.

  In substations, in addition to monitoring and control work, work associated with inspection and maintenance is required, and in some cases, equipment work is also required. In contrast, substation equipment, such as transformers, is normally energized and charged, so it is necessary to ensure the safety of workers performing inspection, maintenance, and construction due to the risk of electric shock. is there.

For this reason, in the substation, when working near the charging unit that is energized and charged,
・ Dangerous points are illustrated on the drawings ・ Danger range is indicated at the work site ・ Measures for ensuring safety such as deploying and monitoring a supervisor at the work site are adopted. However, since all of these measures are safety measures based on human judgment, it cannot be said that there is no human error.

  Therefore, it is conceivable to realize proximity detection of a moving body with respect to a dangerous facility at a substation by using a technology that automatically detects a moving body such as a human body without being based on human judgment. As a technique for detecting a moving body, for example, techniques described in Patent Documents 1 to 4 have been conventionally considered.

Patent Document 1 describes that a human body is detected by a proximity switch based on optical, capacitive, and electromagnetic induction principles (paragraph 0025).
Patent Document 2 describes that a human body is detected by a non-prism laser scanner (paragraphs 0005 to 0006).
Patent Document 3 describes human body detection using an ultrasonic sensor and human body detection using a pyroelectric infrared sensor (paragraphs 0002 to 0005).
Patent Document 4 describes human body detection using a reflective infrared sensor (paragraph 0008).
In addition, a technique for detecting a moving body based on a captured image of a camera is already known.
Japanese Patent Laid-Open No. 05-211708 Japanese Patent No. 3125969 (Japanese Patent Laid-Open No. 08-160127) JP 08-218310 A JP 2004-264210 A

In a substation, the allowable proximity distance differs depending on the type of equipment. For example, taking a power transmission line as an example, it may occur that a proximity allowable distance of one power transmission line is 0.6 m, whereas a proximity allowable distance of another power transmission line is 1.5 m. In general, various types of equipment having different proximity permissible distances are mixed in the same substation.

  However, when considering the difference in proximity permissible distance according to the type of equipment, the sensors for detecting a moving body such as a human body for each equipment are matched to the permissible proximity distance. When it must be installed, there is a problem that a great deal of labor is required. In addition, whenever a facility change occurs due to facility construction, the sensors must be re-installed each time, which is extremely troublesome.

  Although the details are unknown in Patent Document 2 described above, it is described that a warning area is set on the screen of a television monitor (paragraph 0011). However, when the permissible proximity distance is predetermined as a numerical value, the operation is not easy if the predetermined allowable proximity distance is set for each facility on the screen of the television monitor.

  As mentioned above, although the prior art and its subject were demonstrated taking the substation as an example, such a subject is not a subject limited to a substation but a universal subject with respect to a similar facility.

  An embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a schematic diagram schematically showing a flow of power supply through a substation in which an alarm system according to an embodiment of the present invention is used. Electricity is produced at the power plants 101, 102, 103. As the power plants 101, 102, and 103, there are a hydro power plant 101, a thermal power plant 102, and a nuclear power plant 103. The electricity generated by these power plants 101, 102, 103 is sent to a large or medium-scale destination via a plurality of substations 121, 122 connected by a transmission line 111, or the substation 121 , 122 through a power distribution facility 131 connected by a power distribution line 112 and sent to a small destination by a lead-in wire 113. Large-scale destinations are, for example, the large factory 141, the railway 142, and the like. Medium-scale destinations are, for example, small and medium factories 143, buildings 144, and the like. The small destinations are, for example, a store 145, a street light 146, a general household 147, and the like.

  Electricity generated by the power plants 101, 102, 103 is sent to the primary substation 121 at 220,000 to 110,000 volts. In the primary substation 121, the transmitted electricity is stepped down to 110,000-66,000 volts and transmitted to the distribution substation 122, the large factory 141, the railway 142, and the like. The distribution substation 122 further reduces the voltage to 22,000 to 6,000 volts, transmits power to the small and medium factories 143 and the building 144 via the transmission line 111, and transmits power to the distribution facility 131 via the distribution line 112. Thus, the main roles of the substations 121 and 122 are to increase (boost) or lower (decrease) the voltage in accordance with the destinations 141 to 147. In addition, the substations 121 and 122 make adjustments to keep the transmission voltage constant, cut off the transmission to the transmission line 111 and the distribution line 112 in which a failure has occurred, the hydropower station 101 and the thermal power station 102. The power flow is adjusted in accordance with the shutdown of the nuclear power plant 103.

  The alarm system of the present embodiment is constructed as an alarm system suitable for use in the primary substation 121. However, this does not mean that the alarm system of the present invention is used only in the primary substation 121. The alarm system of the present invention includes a large number of power plants 101, 102, 103, distribution substation 212, power distribution equipment 131, power transmission line 111, power distribution line 112, service line 113, or other equipment not illustrated in FIG. It can be used with other facilities.

  FIG. 2 is a schematic diagram showing a schematic arrangement of the primary substation 121. The primary substation 121 includes a substation facility 201 and an office 202. The substation equipment 201 includes various kinds of equipment required directly or indirectly for substation. The substation equipment 201 and the office 202 are connected via various signal lines 203.

  FIG. 3 is a schematic diagram illustrating an example of the substation equipment 201. As an example of the substation equipment 201, equipment A, equipment B, equipment C, and a heat source X are provided. These equipment A, equipment B, and equipment C are, for example, transformers, circuit breakers, disconnectors, lightning arresters, instrument transformers, electric wires / cables, switchboard 201a (see FIGS. 4 and 10), phase adjusting equipment, relays. It is a point device or includes them in part. The equipment A, equipment B, and equipment C may be gas insulated switchgear (GIS), cubicles, or may be included in a part thereof. The heat source X is, for example, a boiler or a steam pipe.

In the example of the substation equipment 201 shown in FIG. 3, it is assumed that work is performed at the equipment A. For this reason, the facility A is in a stopped state. On the other hand, the equipment B and the equipment C have a risk of electric shock in terms of current passing therethrough. In FIG. 3, the respective dangerous areas 211 b and 211 c of the equipment B and the equipment C are indicated by a one-dot chain line. As is clear from FIG. 3, the dangerous area 211 b of the facility B is wider than the dangerous area 211 c of the facility C. As described above, the range of the dangerous area (for example, the dangerous areas 211b and 211c) differs depending on the type of each facility (for example, the facilities A, B, and C). Moreover, the heat source X has a risk of burns in terms of high temperature.

  FIG. 4 is a functional block diagram of the alarm system. The alarm system includes a camera 301, an alarm device 401, an infrared temperature sensor 501, and a system control unit 601 as an alarm device as hardware elements. The functional block diagram shown in FIG. 4 schematically shows functions mainly executed by the microcomputer 602 (see FIG. 11) included in the system control unit 601. Hereinafter, functions executed by the microcomputer 602 (see FIG. 11) will be described with reference to the schematic diagrams shown in FIGS.

  Here, FIG. 5 is a schematic diagram illustrating an example of an image captured by the camera 301. FIG. 6 is a schematic diagram illustrating an example of an image in which a desired position is specified in an image captured by the camera 301. FIG. 7 is a schematic diagram illustrating an example of a target facility selection screen. FIG. 8 is a schematic diagram illustrating an example of a screen when a person enters the alarm area. FIG. 9 is a schematic diagram illustrating an example of a screen when a person enters the stop area. These images shown in FIGS. 5 to 9 are display screen examples displayed on the display device 605 (see FIG. 11) of the system control unit 601.

  A captured image of the target facility photographed by the camera 301 is transmitted to the system control unit 601 as an image signal by the image signal output unit 302. In the system control unit 601, the image signal receiving unit 603 receives an image signal that is a captured image of the camera 301 transmitted from the image signal output unit 302. The display output unit 604 displays and outputs the captured image on the display device 605 based on the received image signal. The captured image displayed and output on the display device 605 is, for example, an image illustrated in FIG.

The position designation unit 606 allows designation of a desired position and target equipment located at the desired position by the input device 607 (see FIG. 11) for the captured image displayed and output on the display device 605. The input device 607 includes a touch panel 607a (see FIG. 11) as an example. Therefore, the designation of the desired position is performed by, for example, touch designation of the position A indicated by the dot pattern in FIG. 6 using the touch panel 607a. The specification of the target equipment located at the desired position that is touch-designated in this way can be specified by a pull-down menu B displayed as a pull-down in FIG. The pull-down menu B displays the equipment name Ba so that the touch designation by the touch panel 607a is possible, and the equipment name Ba that does not fit in the display area of the pull-down menu B can be moved and displayed by the display movement tool Bb.

  As described above, the position specifying unit 606 has shown an example that allows the input device 607 to specify the desired position and the target equipment located at the desired position for the captured image displayed and output on the display device 605. As another example, The position designation unit 606 may be configured to allow only designation of a desired position by the input device 607 for the captured image displayed and output on the display device 605. In this case, the system control unit 601 must know in advance which equipment is the target equipment located at the designated desired position. Therefore, the system control unit 601 has a data structure that associates an image signal, which is a captured image of the camera 301 transmitted from the image signal output unit 302, and equipment (for example, equipment A, B, C, heat source X). There is a need.

  The area setting unit 608 sets the warning area C (see FIGS. 8 and 9) and the stop area based on the position specified by the position specifying unit 606, and stores them in the area setting file 609 as a storage area. The alarm area C is an area set so that an alarm is sounded by the alarm device 401 when a moving body D such as a human enters the target facility. Such an alarm area C corresponds to the dangerous areas 211b and 211c shown in FIG. A stop area | region is an area | region set so that the said target equipment may be stopped when the mobile bodies D, such as a person, approached with respect to the target equipment. The stop area forms part of the alarm area C, but is set as an area closer to the target facility than the alarm area C. When setting the warning area C and the stop area, the area setting unit 608 defines a distance definition file 610 that defines a warning distance and a stop distance for each target equipment (for example, equipment A, B, C, heat source X) (see FIG. 12), information on the alarm distance and stop distance of the target equipment located at the position specified by the position specifying unit 606 is acquired, and the alarm area C and stop area are set. At this time, the microcomputer 602 included in the system control unit 601 includes, as an example, an area from the position specified by the position specifying unit 606 to a position separated from the alarm distance 610b and the stop distance 610d defined in the distance definition file 610. These are set as an alarm area C and a stop area, respectively. As another example, the microcomputer 602 included in the system control unit 601 receives the output signal of the infrared temperature sensor 501 transmitted to the system control unit 601 by the temperature signal output unit 502 by the temperature signal reception unit 611, and receives the position designation unit. Areas from the part that overlaps the position specified by 606 to the position separated by the alarm distance 610b and the stop distance 610d defined in the distance definition file 610 from the part that is hot are designated as the alarm area C and the stop area, respectively. May be set.

  In any case, since the distance definition file 610 defines the alarm distance 610b and the stop distance 610d for each target facility (for example, the facilities A, B, C, and the heat source X), it is obtained for each target facility. Even if the alarm distance or the stop distance is different, the alarm area C and the stop area can be easily set.

The process so far is a preparation process for executing an alarm operation using the alarm system. The alarm operation is executed by the analysis determination unit 612. The analysis determination unit 612 performs an analysis process based on an image signal that is a captured image of the camera 301 received by the image signal reception unit 603, and determines that the moving body D has entered the alarm region C or the stop region. If the analysis determination unit 612 determines that the moving object D has entered the alarm region C, the analysis determination unit 612 outputs an alarm signal to the alarm signal reception unit 402 of the alarm device 401 disposed in the vicinity of the target facility. At this time, the analysis determination unit 612 displays a warning on the display device 605. As the alarm display, for example, as illustrated in FIG. 8, an individual display Da for calling attention around the detected moving body D and an alarm display E indicated by the characters “alarm” are displayed. . In addition, when the analysis determination unit 612 determines that the moving body has entered the stop area, the analysis determination unit 612 outputs a stop signal for stopping the operation of the target facility to the switchboard 201a of the primary substation 121. At this time, the analysis determination unit 612 performs a stop display on the display device 605. As the stop display, for example, as illustrated in FIG. 9, an individual display Da that draws attention around the detected moving body D and a stop display F indicated by the characters “stop” are displayed. .

  Thus, in the alarm system of the present embodiment, when a moving body D such as a human enters the set alarm area C, an alarm signal is output to the alarm device 401 located in the vicinity thereof, and accordingly An alarm sound can be output from the alarm device 401 to call attention. At this time, the operator who is viewing the display device 605 can show at a glance that the moving body D has entered the alarm area C by displaying the alarm display E. Similarly, the operator who is viewing the display device 605 can show at a glance that the moving body D has entered the stop area by displaying the stop display F. In addition, since the individual display Da is displayed around the moving body D, even if there are a plurality of moving bodies D such as humans in one display screen, it can be determined which moving body D has entered the alarm area C or the stop area. It can be shown at a glance.

  The function executed by the microcomputer 602 included in the system control unit 601 has been described above based on the functional block diagram shown in FIG. Therefore, the configuration of the system control unit 601 and the processing contents of the microcomputer 602 will be described below.

  FIG. 10 is a block diagram showing a system configuration of the entire alarm system. The camera 301, the alarm device 401, the infrared temperature sensor 501, the system control unit 601, and the switchboard 201 a of the primary substation 121 described above are connected by a network 701. The network 701 may use a LAN as an example, and may use a WAN as another example. In particular, the network 701 interposed between the camera 301 and the system control unit 601 needs to be a network wiring that can transmit and receive data between information communication devices. The network 701 interposed between the alarm device 401, the infrared temperature sensor 501, and the switchboard 201a and the system control unit 601 is not necessarily between information communication devices depending on the configuration of the alarm device 401, the infrared temperature sensor 501, or the switchboard 201a. The network wiring need not be capable of data transmission / reception, and may be a signal line or the like.

  FIG. 11 is a block diagram illustrating a hardware configuration of the system control unit 601. The microcomputer 602 that forms the core of the system control unit 601 includes a CPU 651 that executes various arithmetic processes and controls each unit centrally, a ROM 652 that stores fixed data in a fixed manner, and a RAM 653 that stores variable data in a rewritable manner. They are connected via a bus line 654. For example, a hard disk drive (HDD) 655 and a CD-ROM drive 656 are also connected to the microcomputer 602 via the bus line 654. As an example, a CD-ROM 657 is set in the CD-ROM drive 656, the alarm computer program described in the CD-ROM 657 is read, and the read alarm computer program is written in the HDD 655. All or part of the alarm computer program written in the HDD 655 is transferred to the RAM 653 when the microcomputer 602 is started, so that the access speed is increased.

  The display device 605 and the input device 607 described above are also connected to the microcomputer 602 via the bus line 654. The display device 605 is configured by a liquid crystal display as an example, and a touch panel 607a is installed on the display surface of the liquid crystal display. The input device 607 includes, for example, a pointing device such as a keyboard and a mouse (not shown) in addition to the touch panel 607a.

An interface 658 is also connected to the microcomputer 602 via the bus line 654 so that the system controller 601 and other devices can communicate with each other via the network 701 or can output signals.

  The alarm computer program supports the generation of the distance definition file 610 (see FIG. 12) and the region setting file 609 (see FIG. 13). As an example, the microcomputer 602 performs the processing illustrated as flowcharts in FIGS. Let it run. The distance definition file 610 and the area setting file 609 are generated on the RAM 653 as an example and backed up to the HDD 655.

  FIG. 12 is a schematic diagram showing the data structure of the distance definition file 610. The distance definition file 610 has a data structure that stores an alarm distance 610b, an alarm necessity 610c, a stop distance 610d, and a stop necessity 610e for each equipment 610a corresponding to the target equipment to be alarmed. These data can be freely set using the input device 607 by the processing of the microcomputer 602 according to the alarm computer program.

  FIG. 13 is a schematic diagram showing the data structure of the area setting file 609. The area setting file 609 has a data structure for storing an alarm area 609b and a stop area 609c for each camera 609a associated with each camera 301. As already described with reference to FIG. 4, the region setting unit 608 sets the warning region C and the stop region based on the position specified by the position specifying unit 606 and stores them in the region setting file 609. The alarm area C and the stop area set in this case are stored as an alarm area 609b and a stop area 609c shown in FIG. That is, when setting the warning area C and the stop area by the area setting unit 608, the operator looks at the display screens illustrated in FIGS. 5 to 7 displayed on the display device 605, for example. This display screen is a display screen based on a captured image taken by a specific camera 301. Therefore, when an operation for setting an alarm area and a stop area is performed on the display screen using the touch panel 607a, the operation is performed in accordance with the data of the camera 609a that identifies the camera 301 that displays the display screen. Data based on the input is stored in the alarm area 609b and the stop area 609c.

More specifically, the location designation unit 606 designates a certain area in a facility, for example, a location A as illustrated in FIG. 6, and a facility name Ba from the pull-down menu B illustrated in FIG. Assuming that In this case, as the processing of the microcomputer 602 according to the alarm computer program, the equipment corresponding to the designated equipment name Ba is searched from the equipment 610a of the distance definition file 610, and the distance set in the corresponding alarm distance 610b. Based on the above, the warning area C is obtained by calculation, the stop area is obtained by calculation based on the distance set to the corresponding stop distance 610d, and the calculated alarm area C and stop area data are set together with the equipment data, respectively. The process of storing the alarm area 609b and the stop area 609c of the file 609 is executed. Operation of the alarm region C by the microcomputer 602, as an example, and calculates the distance component apart space that has been set in the alarm distance 6 10b in the distance definition file 610 from the specified position A by the touch panel 607a as warning area . Similarly, the calculation of stopping area by the microcomputer 602, as an example, the distance component apart space that has been set in the stopping distance 6 10d in the distance definition file 610 from the specified position A by the touch panel 607a as a stop region calculate. In these calculation processes, when the position A is specified based on a three-dimensional image as in the display screens illustrated in FIGS. 5 to 7, as an example, on the condition that the position A is specified in a frame shape, It determined the three-dimensional position of the specified position a in a frame shape, alarm distance 6 10b in the distance definition file 610 from the three-dimensional position obtained, obtained horizontally extending a distance that is set in the stopping distance 6 10d The area is obtained as alarm area C and stop area data. Therefore, the warning area C and the stop area in this case are areas in which all of the three-dimensional axes (vertical and horizontal heights) are specified. On the other hand, when the display screen of the display device 605 is a two-dimensional screen imaged by the camera 301 from the top, the position A may be specified two-dimensionally as an example. That is, in this case, the warning distance 6 10b of the distance in the definition file 610 from the position of the specified position A as a line, get the distance set in the stopping distance 6 10d as horizontally extend in height infinity This area may be obtained as data for the warning area C and the stop area. Therefore, the warning area C and the stop area in this case are areas in which only the two-dimensional axis (vertical and horizontal only) is specified.

  As another embodiment relating to the process of searching for equipment from the equipment 610a of the distance definition file 610, the image data captured by the camera 301 and the data related to the equipment are associated with each other without specifying the equipment using the pull-down menu B. You can keep it. In this case, the operation of equipment designation by the pull-down menu B can be omitted.

  FIG. 14 is a flowchart showing a flow of processing for setting the alarm region 609b and the stop region 609c in the region setting file 609 (processing for creating the region setting file 609). In this process, first, it waits for the determination of the presence / absence of position designation as exemplified by designation of position A in FIG. 6 (step S101). If it is determined that the position has been specified (Y in step S101), for example, it waits for determination of whether or not equipment is specified by the pull-down menu B in FIG. 7 (step S102), and if it is determined that the equipment has been specified. (Y in step S102), the search process of the distance definition file 610 is executed (step S103). Then, the alarm area C and the stop area are calculated by the arithmetic processing of the CPU 651, and the alarm area C and the stop area 609c are stored in the area setting file 609 corresponding to the data of the corresponding camera 609a. Is stored. Thereby, an area setting file 609 is created.

  FIG. 15 is a flowchart showing a flow of processing for determining the position information of the moving object. When the capture of the image signal is executed (step S201, the image signal receiving unit 603), the image analysis is performed (step S202), and the position information of the moving body D such as a human is determined (step S203, the analysis determining unit). 612). The determination process in step S203 is executed based on an image processing technique based on the captured image signal. As an example, a method of comparing temporal frames included in an image signal based on a captured image captured by the camera 301 with time can be employed. In other words, if there is a difference between the data of the image frame at a certain time and the data of the subsequent image frame in time, it is found that the moving body D has moved. In this case, it is possible to recognize where the movement of the moving object D has occurred by determining which region of the data has a difference in the image. As another example, the same area may be imaged with a plurality of cameras 301 to generate a 3D imaging area. In this method, it is possible to determine that the moving body D has moved by comparing captured images taken by the respective cameras 301. Similarly, it is possible to recognize where the movement of the moving object D has occurred by determining which region of the data has a difference in the image. In any case, any known image processing technique may be used for the determination process in step S203.

FIG. 16 is a flowchart showing the flow of alarm signal output processing. In step S301, it is determined whether or not an alarm area has been entered. This determination is executed based on whether or not a moving body D such as a human has entered the alarm area C specified by the data of each alarm area 609b set in association with each camera 609a in the area setting file 609. . Whether or not the moving body D has entered the alarm area C is determined based on the position information of the moving body D obtained by the processing of FIG. When it is determined that the moving body D has entered the warning area C (Y in step S301), the distance illustrated in FIG. 12 based on the facility data accompanying the data of the corresponding warning area 609b. The facility 610a of the definition file 610 is searched, and the status data of the necessity / unnecessity of alarm 610c corresponding to the corresponding facility is referred to (step S302). As a result, when the alarm is unnecessary (N in Step S302), the process returns to the determination process in Step S301. On the other hand, when it is determined that an alarm is necessary (Y in step S302), a process of outputting an alarm signal to the alarm device 401 via the network 701 is executed (step S303). As a result, the alarm device 401 installed in the vicinity of the alarm area C into which the moving body D has entered is driven, an alarm is issued, and attention is drawn. Thereafter, if it is determined that the moving body D has deviated from the alarm area C (Y in step S304), a process of outputting an alarm stop signal to the alarm device 401 via the network 701 is executed (step S305). Thereby, the drive of the alarm device 401 is stopped.

FIG. 17 is a flowchart showing the flow of the stop signal output process. In step S 4 01, it is determined whether the entry of the stop region. This determination is performed based on whether or not a moving body D such as a human has entered a stop area specified by the data of each stop area 609c set in the area setting file 609 in association with each camera 609a. Whether or not the moving body D has entered the stop area is determined based on the position information of the moving body D obtained by the processing of FIG. When it is determined that the moving body D has entered the stop area (Y in step S401), the distance definition illustrated in FIG. 12 based on the facility data accompanying the data of the corresponding stop area 609c. The facility 610a in the file 610 is searched, and the status data of the necessity / unnecessity of stop 610e corresponding to the corresponding facility is referred to (step S402). As a result, when the stop is unnecessary (N in step S402), the process returns to the determination process in step S401. The other hand, if it is determined that it is necessary to stop (Y in step S402), the processing of outputting a stop signal via the network 701 is performed toward the switchboard 201a (Step S 4 03) . As a result, the corresponding facility stop process is executed. Thereafter, the operation of the stopped facility is resumed by operating the switchboard 201a.

  In the present embodiment, an example in which the alarm computer program stored in the CD-ROM 657 is installed in the HDD 655 and the processing to be executed by the system control unit 601 is executed by the microcomputer 602 is shown. On the other hand, as another embodiment, the microcomputer 602 may be configured as a sequencer and may have a firmware configuration in which an alarm computer program is recorded in, for example, the ROM 652, or an ASIC configuration.
