Description

  The present invention relates to an abnormal equipment detection system, and more particularly to an abnormal equipment detection system that notifies an abnormal occurrence signal that a building equipment installed in a building is abnormal.

  The building is provided with various building facilities such as an elevator, an escalator, an air conditioning facility, a power supply facility, a water supply facility, and a fire prevention device. For maintenance of these building facilities, in addition to the maintenance engineer resident in the building, each of these building facilities is provided with an abnormality detection device and connected to a remote monitoring device such as a building facility maintenance management company via a public line. Monitoring system may be taken. The public line is a public telephone line or a wireless line that is open to the public. For example, in the event of an earthquake, the public line is cut off and an abnormal signal is transmitted from the building facilities to the remote monitoring device. Things that cannot be done happen. Even when the public line is not severed, in a wide-area disaster, etc., the public line becomes congested, and it often takes time to connect the building facilities of the building to the remote monitoring device.

  In such a case, for example, the user may be isolated in the elevator car while the elevator is urgently stopped, but the remote monitoring device cannot detect the abnormal state. Also, in the case of a wide-area disaster, a maintenance engineer (Field Engineer: FE) of a building equipment maintenance management company rushes to the site and performs an emergency patrol, but an abnormal state occurs in which building equipment in which building. Since it is unclear whether it is unknown, it takes time to arrive at an abnormal building facility. For example, it may take time to rescue a user who is isolated in an elevator car.

  According to the prior art, means for informing the outside using an emergency rescue signal, light emission corresponding to the rescue level, etc. is described. In these methods, since a signal for rescue must be continuously output until the rescuer rushes, power consumption such as a battery increases. According to the technique of Patent Document 1, battery consumption can be suppressed to some extent, but there is a limit.

  An object of the present invention is to provide an abnormal facility detection system that can further suppress power consumption for identifying the presence of an abnormal state of a building facility. Another object is an abnormal equipment detection system that can further suppress the power consumption to make it possible to identify the presence of abnormal conditions in building equipment by acting as a report to the remote monitoring device when a failure related to remote monitoring occurs. Is to provide.

  An abnormal equipment detection system according to the present invention is provided in a building equipment installed in a building, an abnormality detecting means for detecting that the building equipment is abnormal and outputting an abnormal signal, and an abnormality detection means provided in the building. Corresponding to the abnormality signal output by the means, the abnormality occurrence signal output means that can output the abnormality occurrence signal and the transmission command signal that requests the abnormality occurrence signal generation means to output the abnormality occurrence signal are transmitted from the outside And a transmission command acquisition means for acquiring the transmission command accordingly.

  In the anomaly equipment detection system according to the present invention, an anomaly occurrence notifying device for reporting an anomaly occurrence using a public line to a predetermined remote monitoring device provided in a building and outputting an anomaly signal by the anomaly detection means A failure detection device that detects that the failure notification device is in a state incapable of reporting to the remote monitoring device and outputs a notification failure status signal. It is preferable to output an abnormality occurrence signal when a status signal is output and a transmission command signal is received.

It waits to acquire a transmission command signal for requesting output in response to an external transmission. Thus, even if an abnormality signal is output, the abnormality occurrence signal is not output immediately, so that power consumption for outputting the abnormality occurrence signal can be suppressed.

  In addition, if a transmission command signal is obtained, an abnormality occurrence signal is output unless there are other necessary conditions. For example, if a maintenance engineer (FE) is patroling the site, is there an abnormality? If a transmission command signal is output to check the occurrence, it is possible to immediately know whether or not an abnormality has occurred, and to improve the efficiency of patrol on site.

  Further, in the abnormal equipment detection system, when an abnormality signal is output by the abnormality detection means, the occurrence of abnormality is notified to a predetermined remote monitoring device using a public line. At this time, if it is in a state incapable of reporting to the remote monitoring device, an abnormality occurrence signal is output when a transmission command signal is received. In this way, it is detected that the building equipment installed in the building is abnormal, and when the communication path that reports the occurrence of abnormality using the public line to the remote monitoring device breaks down, the abnormality occurrence is notified instead. Can do.

  In addition, in the abnormal equipment detection system, after outputting an abnormality occurrence signal, transmission is continued at a predetermined time interval until a reception notification from the portable transmission / reception means is obtained. Can be done automatically.

  In addition, since the abnormality facility detection system includes a stopping means that can stop the output after outputting the abnormality occurrence signal, for example, when the abnormality processing is completed, the output of the abnormality occurrence signal is stopped and required. Electric power or the like can be suppressed.

  In addition, the abnormal equipment detection system is equipped with a backup power source that backs up the operation of the abnormal signal generator in the event of a power failure, making it easy to identify the presence of an abnormal condition even during a power failure, especially under dark conditions. .

Moreover, although the signal which detects that the emergency button was operated by the user in the elevator car which stopped urgently by the occurrence of an earthquake is demonstrated as an abnormal signal, it does not need to be at the time of the occurrence of an earthquake. Moreover, even if it is a case where building facilities are an elevator, the signal which detects abnormality other than this may be sufficient. For example, a signal for detecting an elevator operation abnormality may be used. Further, when the building facility is other than the elevator, of course, it may be an abnormality detection signal corresponding to the building facility. Further, a signal detected by a seismometer, anemometer, rain gauge, earth leakage detector, or the like can be used as a primary abnormality signal.

  The remote monitoring device 22 is a device that acquires various state signals from each building facility and monitors the state of each building facility. As described above, the remote monitoring device 22 is provided in a building facility maintenance management company in charge of maintenance of the building facility. It is done. However, when there is an office of the building equipment maintenance management company in the building 4 as in a large-scale building, the remote monitoring device 22 may be provided in the building 4.

  The various status signals from each building facility transmitted to the remote monitoring device 22 include identification information of the building 4 where the building facility is provided and identification information of the building facility. When the abnormal signal is a signal for detecting that the emergency button 14 from the elevator car 8 is pressed, the building number for identifying the building 4, the elevator number for identifying the elevator car 8, and the emergency button 14 are pressed. A signal identification number indicating that the recording has been performed is included.

  The abnormality occurrence notification device 18 is provided between the various building facilities and the remote monitoring device 22. When an abnormal signal set in advance is output from the various building facilities, the abnormality notification device 18 acquires this and sends it to the remote monitoring device 22. This is an automatic alarm device having a function of automatically reporting the occurrence of an abnormality via the line 20.

  The sound generating device 30 outputs an abnormality occurrence signal that outputs a predetermined sound as an abnormality occurrence signal instead of the abnormality occurrence notification device 18 under the control of the control device 50 when the abnormality occurrence notification device 18 cannot normally make a notification. It is an output means. As the sound producing device 30, in addition to a siren, a buzzer, a bell, etc., a speaker that can output sound can be used.

  The light emitting device 32 is a device having a function of outputting an abnormality occurrence signal under the control of the control device 50, similarly to the sound generation device 30. Here, not a sound but a predetermined light is output. As the light emitting device 32, a searchlight, a lamp, a light emitting diode, a neon tube, or the like can be used.

  Similarly to the sound generator 30 and the light emitting device 32, the wireless transmission / reception device 34 is a device having a function as an abnormality occurrence signal output unit that outputs an abnormality occurrence signal under the control of the control device 50. Here, a predetermined radio signal is output instead of sound and light. The wireless signal can include various status signals from each building facility. The wireless transmission / reception device 34 also has a function as a transmission command signal receiving unit that receives a transmission command signal from the portable transmission / reception device 42. Here, the transmission command signal is a signal that requests the abnormality occurrence signal output means to output the abnormality occurrence signal when the abnormality signal is output.

  The wireless transmission / reception device 34 can be configured to include an antenna and a wireless transmission / reception circuit capable of transmitting and receiving a wireless signal within a predetermined wireless output intensity range in a predetermined frequency band. Note that the wireless transmission / reception device 34 can continue transmission at a predetermined time interval after starting the output of the abnormality occurrence signal until obtaining a reception notification from the portable transmission / reception device 42. Thus, transmission can be continued while suppressing power consumption.

  As described with reference to FIG. 1, the portable transceiver 42 is a portable wireless transceiver that is carried by a maintenance engineer (FE) 40, is an abnormality occurrence signal receiver, and is a transmission command signal transmitter. The portable transmission / reception device 42 includes a transmission command transmission unit 44 that is a transmission circuit that transmits a transmission command signal to the wireless transmission / reception device 34, and an abnormality occurrence signal that is a reception circuit that receives an abnormality occurrence signal from the wireless transmission / reception device 34. The receiver 46 is configured to include a signal processing circuit that converts received information into display data, a display that displays the converted display data, and the like. As such a portable transceiver 42, a radio transceiver having a specification that is easy to handle for the maintenance engineer (FE) 40 and a specialized specification, or a mobile phone incorporating the specialized specification can be used.

  As described above, since the wireless signal transmitted from the wireless transmission / reception device 34 includes various state signals of each building facility, the information is displayed on the display. In the example of FIG. 1, a building number, an elevator number, a signal identification number indicating that the emergency button 14 has been pressed, and the like are displayed. As a result, the maintenance engineer (FE) 40 knows that the user is locked in the elevator car, and immediately determines which elevator car in which building the elevator car 8 in which the user is locked is. Can be recognized.

  The backup power supply 16 shown in FIG. 1 is an emergency power supply (UPS) having a function of supplying emergency power to a power supply in the event of a power failure, which is provided in the building 4 as an element constituting the abnormal equipment detection system 10. is there. For example, it has a function of supplying emergency power to the sounding device 30, the light emitting device 32, and the wireless transmission / reception device 34. As the backup power source 16, an appropriate power generation device, power storage device, or the like that can be automatically switched to a normal power source in the event of a power failure can be used.

  As described above, the control device 50 in FIG. 2 has a function of controlling the operation of each element constituting the abnormal facility detection system 10 as a whole. As such a control device 50, an appropriate control circuit or a computer can be used. The control device 50 includes a switching control unit 52 and an output control unit 54.

  The switching control unit 52 has a function of switching so that an abnormality occurrence signal is output by the sound generation device 30, the light emitting device 32, and the wireless transmission / reception device 34, which are abnormality signal generation means, when the abnormality occurrence notification device 18 cannot report an abnormality signal. Have. The switching control unit 52 detects that the building equipment installed in the building 4 is abnormal and outputs an abnormality signal, and the abnormality occurrence reporting device 18 is in a state incapable of reporting to the remote monitoring device 22. A notification disabling detection module 58 that detects the fact and outputs a notification disabling state signal, a transmission command acquisition module 60 that acquires a transmission command signal that requests output of an abnormality occurrence signal, Is output, and when a transmission command signal is acquired, an abnormality occurrence signal output module for outputting an abnormality occurrence signal by the sound generation device 30, the light emitting device 32, and the wireless transmission / reception device 34 instead of the notification of the abnormality occurrence notification device 18 62 is comprised.

  The output control unit 54 has a function of controlling operations of the sound generation device 30, the light emitting device 32, and the wireless transmission / reception device 34 that are abnormal signal generating means. The output control unit 54 receives the reception notification acquisition module 66 for acquiring the reception notification from the portable transmission / reception device 42 to control the operation of the wireless transmission / reception device 34, and when the maintenance engineer (FE) 40 completes the abnormal process. And an output stop processing module 68 for detecting the operation of the output stop switch 38 and stopping the output of the abnormal signal generating means. As the output stop switch 38, for example, a switch that stops the operation of the sound generator 30, the light emitting device 32, and the wireless transmission / reception device 34 by a manual operation of a maintenance engineer (FE) can be used.

  These functions can be realized by software. Specifically, it can be realized by executing a remote monitoring failure notification proxy processing program. Some of these functions may be realized by hardware.

  The operation of the above configuration, particularly each function of the control device 50, will be described in detail with reference to the flowchart of FIG. The flowchart of FIG. 3 is a flowchart showing a procedure for processing an abnormal state when an abnormality signal is output from the building equipment of the building 4 and a failure relating to the abnormality occurrence notification device 18 occurs. The procedure in FIG. 3 includes a procedure performed by a maintenance engineer (FE) 40 that has recognized the abnormality occurrence signal in addition to the procedure executed by the function of the control device 50. In FIG. 3, the procedure executed by the control device 50 is indicated by a solid line frame, and the procedure performed by the maintenance engineer (FE) 40 is indicated by a broken line frame. Each procedure indicated by a solid line frame corresponds to each processing procedure of the remote monitoring failure notification proxy processing program.

  In FIG. 3, when abnormality detection (S12) is performed from the normal state (S10), the procedure from S14 is performed. The abnormality detection process is executed by the function of the abnormality detection module 56 of the control device 50. Specifically, it is detected that the emergency button 14 provided on the elevator car 8 is operated by the user, and an abnormal signal is output.

  When an abnormality signal is output, a notification command for issuing an abnormality occurrence notification is issued (S14). Specifically, an acquisition of an abnormality signal is acquired, and an instruction for notifying the remote monitoring device 22 of the occurrence of an abnormality is transmitted to the abnormality notification device 18 via the public line 20.

  Then, it is determined whether or not reporting is impossible (S16). This process is executed by the function of the report failure detection module 58 of the control device 50. Inability to report means that the failure occurrence reporting device 18 itself has a failure, the public line 20 is cut off and the notification is interrupted there, the remote monitoring device 22 has a failure, and the public line 20 And the case where the notification of the occurrence of abnormality does not reach the remote monitoring device 22 within a predetermined time is included. Whether or not the notification is impossible is determined by requesting the remote monitoring device 22 to transmit a reception notification when the notification is received, and when the reception notification does not return within a predetermined time. Can be determined to be impossible. For example, 5 seconds or the like can be set as the predetermined time.

  If it is not determined that the notification is impossible, the remote monitoring device 22 normally receives a notification of the occurrence of an abnormality (S40). In this case, the remote monitoring device 22 analyzes the information included in the notification of the occurrence of the abnormality, and issues an instruction to rush to the maintenance site (FE) 40 to the site where the abnormality has occurred as necessary. The notification of the occurrence of abnormality includes various status signals of building equipment. Here, the building number, the elevator number, the signal identification number indicating that the emergency button 14 has been pressed, and the like that are included in the notification of the occurrence of an abnormality. It is possible to automatically issue an on-site express command to the maintenance engineer (FE) 40 based on such information.

  For example, the data of the field in charge of the maintenance engineer (FE) 40, the relationship data between the time zone and the location, etc. are sequentially stored in the database in advance, and collation with the information included in the notification of the occurrence of abnormality is predetermined. Follow the steps. As a result, the maintenance engineer (FE) who can rush to the site where the abnormality has occurred is identified, and information related to the site where the abnormality has occurred is automatically transmitted via the mobile phone carried by the maintenance engineer (FE) 40. I can do it. Therefore, the maintenance engineer (FE) 40 rushes to the site where the abnormality occurs. The procedure after the arrival at the site (S30) will be described later.

  If it is determined in S16 that the notification is impossible, it is continued to redial the notification to the remote monitoring device 22 via the public line 20, and it is further determined whether or not a call command signal has been acquired (S18). ). This step is executed by the function of the transmission command acquisition module 60 of the control device 50. Specifically, it is determined whether or not a call command signal from portable transmitter / receiver 42 has been received. When the transmission command signal is not received, it waits until it is received and does not proceed to the next S20.

  If it is determined in S18 that the transmission command signal has been acquired, the standby state is released and switching to the abnormality occurrence signal output is performed (S20). Then, an abnormality occurrence signal is output (S22). This step is executed by the function of the abnormality occurrence signal output module 62 of the control device 50. Specifically, a command to output an abnormality occurrence signal having a predetermined content is given to the sound generation device 30, the light emitting device 32, and the wireless transmission / reception device 34 which are abnormality occurrence signal output means.

  There are three types of anomaly occurrence signal output means, a sound generator 30, a light emitting device 32, and a wireless transmitter / receiver 34, but these three can be used in parallel. It is not very effective to use the light emitting device 32. Conversely, it is difficult to identify and recognize the building 4 even if the sound generator 30 is used in the dark. The wireless transmission / reception device 34 can be considered effective even in the daytime and in the dark. In addition, the light emitting device 32 requires a certain amount of light emission intensity to be visually recognized by the maintenance worker (FE) 40, and it is considered that the power consumption increases. From that point of view, it is preferable to use the sounding device 30 with priority, and to use the light emitting device 32 when the sounding device 30 is less effective.

  In addition, since the wireless transmission / reception apparatus 34 is used only for the function of the abnormality occurrence signal output means after the process of S18, when the sound generator 30 and the light emitting apparatus 32 can sufficiently identify the building and the building equipment, Further, it may not be used as the abnormality occurrence output means. For these reasons, it is preferable to determine in advance a determination method for the three types of usage of the sound generation device 30, the light emitting device 32, and the wireless transmission / reception device 34, and to specify the abnormality occurrence signal output means to be used according to the determination method. .

  As a result, a maintenance worker (FE) 40 who is in the vicinity of the site due to patrol, etc. hears the sound from the sound generator 30 provided on the rooftop of the building 4, visually recognizes the light emission from the light emitter 32, and the wireless transmitter / receiver 34. Is received by the portable transmitting / receiving device 42 and visually recognized on the display, the site where the abnormality has occurred can be easily detected (S28).

Accordingly, the maintenance worker (FE) 40 can quickly arrive at the site of the occurrence of the abnormality, in the above example, at the elevator car 8 where the user is confined (S30).
When it is not determined in S16 that the notification is impossible, the remote monitoring device 22 receives a notification of the occurrence of an abnormality (S40), and when an on-site express command is issued to the maintenance worker (FE) 40 thereby, This is the state of step S30.

  Then, the maintenance engineer (FE) 40 performs an abnormality recovery process (S32). In the above case, the user is rescued from the elevator car 8. When a series of abnormality recovery processing is completed, end processing is performed (S34). In the above example, maintenance check is performed to check whether or not an abnormality has occurred in the elevator, and the maintenance process is terminated when the elevator is normal. Then, the output stop switch 38 described in FIG. 2 is operated to stop the output of the abnormality occurrence signal output means (S36). This step is executed by the function of the output stop processing module 68 of the control device 50. In some cases, S36 may be performed immediately after the completion of the abnormality recovery process of S32, or S36 may be performed together with the arrival at the site of S30.

  The wireless transmission / reception device 34 may be set to stop the transmission of the abnormality occurrence signal when the reception notification from the portable transmission / reception device 42 is acquired. This procedure is executed by the function of the reception notification acquisition module 66 of the control device 50. When such a setting is performed and the output of the abnormality occurrence signal has already stopped before the maintenance worker (FE) 40 arrives at the abnormality occurrence site, the process of S36 for the wireless transmission / reception device 34 is omitted. be able to.

  Then, the report redialing of the abnormality occurrence reporting device 18 is stopped (S38). As a result, the processing of the abnormal state when the abnormality occurrence signal is output and the notification by the abnormality occurrence notification device 18 is impossible is completed.

  In the above description, it is assumed that three conditions are necessary for outputting the abnormality occurrence signal. That is, firstly, it is detected that an abnormality signal of the building facility is output, and secondly, it is impossible for the abnormality notification device 18 to report to the remote monitoring device 22 via the public line 20. And third, that a transmission command signal is acquired. Here, the second condition is not necessarily required for detecting an abnormality of the facility and suppressing power consumption for outputting the abnormality occurrence signal.

Therefore, if the first condition and the third condition are both satisfied, the abnormality occurrence signal can be output. This situation is such that the abnormality occurrence notification device 18 may be normal or abnormal, and a maintenance engineer (FE) 40 appropriately sends a transmission command signal in front of the site when visiting the site. It is possible to immediately determine whether or not there is an abnormality in the building equipment of the building 4 simply by transmitting to the building radio transceiver 34. As described above, when the abnormality occurrence signal is output when the first condition and the third condition are satisfied, the efficiency of the maintenance engineer (FE) 40 on-site patrol is greatly improved.

It is a figure which shows the structure of the abnormal equipment detection system in embodiment which concerns on this invention. In embodiment which concerns on this invention, it is a block diagram of the abnormal equipment detection system centering on a control apparatus.
