Preferably it is a means.

  With the above configuration, when it is detected that the building equipment installed in the building is abnormal, the remote monitoring failure reporting agent system notifies the predetermined remote monitoring device of the occurrence of the abnormality using the public line. Here, when the abnormality occurrence reporting device is in a state incapable of reporting to the remote monitoring device, an abnormality occurrence signal is output instead of the notification of the abnormality occurrence reporting device. At this time, the external environment situation of the building with respect to the output of the abnormality occurrence signal is detected, and the output level of the abnormality occurrence signal output means is changed according to the detected external environment situation. As a result, it is possible to identify the presence of an abnormal condition corresponding to the external environment.

  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 device 34 is an abnormality occurrence signal output unit having a function of outputting 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 device 34 can be configured to include an antenna and a wireless transmission circuit that can transmit a wireless signal within a predetermined wireless output intensity range in a predetermined frequency band. Note that the wireless transmission 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 abnormality occurrence signal reception device 42. Thus, transmission can be continued while suppressing power consumption.

  The abnormality occurrence signal receiving device 42 is a portable abnormality occurrence signal receiving means carried by a maintenance engineer (FE) 40 as described in FIG. The abnormality occurrence signal receiving device 42 includes a reception circuit that can receive an abnormality occurrence signal transmitted from the wireless transmission device 34, a signal processing circuit that converts received information into display data, and a display that displays the converted display data.

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 sensor 36 is an environmental condition detection unit having a function of detecting the external environmental condition of the building 4 with respect to the output of the abnormality occurrence signal. The sensor 36 detects the external environment state of the building 4 with respect to the outputs of the sound generator 30, the light emitting device 32, and the wireless transmitter 34, and therefore combines three types of measuring instruments.

  As the external environmental condition detection for the sound producing device 30, the noise level around the building 4 can be detected. As the sensor 36 in this case, a sound level meter can be used. As the external environmental condition detection for the light emitting device 32, the brightness level around the building 4 can be detected. An illuminometer can be used as the sensor 36 in this case. As the external environmental condition detection for the wireless transmission device 34, the wireless reception sensitivity level around the building 4 can be detected. As the sensor 36 in this case, a monitor reception device can be used to detect the wireless reception sensitivity. Alternatively, it is detected that the reception notification from the abnormality occurrence signal receiving device 42 is received, and when the detection is not detected, the wireless reception sensitivity level around the building 4 can be made low.

  The backup power supply 16 shown in FIG. 1 is an emergency power supply (Urgent Power Supply) having a function of supplying emergency power to a component provided in the building 4 that constitutes the remote monitoring failure notification proxy system 10 in the event of a power failure. UPS). For example, it has a function of supplying emergency power to the sound generator 30, the light emitting device 32, the wireless transmitter 34, and the sensor 36. 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 of FIG. 2 has a function of controlling the operation of each element constituting the remote monitoring failure notification proxy 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 device 34 as 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, and when an abnormality signal is output and a notification disabling state signal is output, a sound is output instead of the notification of the abnormality occurrence notification device 18 The apparatus 30, the light emitting apparatus 32, and the wireless transmission apparatus 34 include an abnormality occurrence signal output module 60 that outputs an abnormality occurrence signal.

  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 device 34 that are abnormal signal generating means. The output control unit 54 detects an external environment state of the building 4 with respect to the output of the abnormality occurrence signal, and outputs that change the output level of the abnormality occurrence signal output unit according to the detected external environment state The abnormality processing by the level change module 64, the reception notification acquisition module 66 that acquires the reception notification from the abnormality occurrence signal reception device 42 to control the operation of the wireless transmission device 34, and the maintenance engineer (FE) 40 is completed. An output stop processing module 68 that detects the operation of the output stop switch 38 to stop the output of the abnormal signal generating means is sometimes included. 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 transmitter 34 by a manual operation of a maintenance engineer (FE) 40 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) 40 that can rush to the site where the abnormality occurred is specified, 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. You 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, the redialing of the notification to the remote monitoring device 22 via the public line 20 is continued, and further switching to the abnormality occurrence signal output is performed (S18). Then, an abnormality occurrence signal is output (S20). This step is executed by the function of the abnormality occurrence signal output module 60 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 device 34, which are abnormality occurrence signal output means.

  As the abnormality occurrence signal output means, there are provided three types of sound generator 30, light emitting device 32, and wireless transmitter 34. These three can be used in parallel, but for example, when the day is bright 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 device 34 can be considered effective even during the day 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. For these reasons, it is preferable that a determination method is determined in advance for the three types of usages of the sound generator 30, the light emitting device 32, and the wireless transmitter 34, and the abnormality occurrence signal output means to be used is specified according to the determination method. .

  Once the abnormality occurrence signal output means to be used is specified, the environmental condition is next detected (S22). This process is executed by the function of the environmental condition detection module 62 of the control device 50. Specifically, the sensor 36 detects the external environment state of the building 4 according to the type of the specified abnormality occurrence signal output means. As described above, the noise level is detected for the sound producing device 30, the illuminance level is detected for the light emitting device 32, and the wireless sensitivity level is detected for the wireless transmission device.

  Then, the output level of the abnormality occurrence signal output means is set (S24), and whether the set output level is sufficient under the external environment condition of the building 4 as compared with the detected environmental condition data. Is determined (S26). When the set output level is insufficient, the output level is reset and the output level is changed so as to be optimal according to the external environment situation. These steps are executed by the function of the output level changing module 64 of the control device 50. For example, when the noise level around the building 4 is high, the sounding intensity of the sounding device 30 is changed so as to increase. When the brightness around the building 4 is bright, the light emitting intensity of the light emitting device 32 is increased. Changed to When the wireless reception sensitivity around the building 4 is poor, the wireless transmission device 34 is changed so as to increase the wireless signal transmission intensity.

  As described above, the sound generation intensity of the sound generator 30, the light emission intensity of the light emitting apparatus 32, and the wireless transmission intensity of the wireless transmission apparatus 34 are changed in accordance with the external environment state of the building 4. As a result, a maintenance worker (FE) 40 in the vicinity of the site due to patrol and the like 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 34 Is received by the abnormality occurrence signal receiving device 42 and visually recognized on the display, the site of occurrence of the abnormality 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 device 34 may be set to stop transmission of the abnormality occurrence signal when the reception notification from the abnormality occurrence signal 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 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 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.

It is a figure which shows the structure of the remote monitoring failure notification agent system in embodiment which concerns on this invention. In embodiment which concerns on this invention, it is a block diagram of a remote monitoring failure notification agent system centering on a control apparatus.
