In FIG. 3, the cage | basket | car 1 and 3 have shown the door closed state, and the cage | basket | car 2 is in the door open state.

In the tuning button display area 26, a plurality of tuning buttons 4a to 6a corresponding to the interphone magnetic devices 4 to 6 and a flight number corresponding to the tuning buttons 4a to 6a are displayed. In the station selection buttons 4a-6a, the communication state of the corresponding interphone magnetic device 4-6 is displayed according to the communication state information from the magnetic communication means 9. As shown in FIG. Specifically, based on the conversion table in Fig. 2, "communication call" is 1 when the communication symbol is 1, "calling" when the communication symbol is 2 and "waiting" when the communication symbol is 3. In FIG. 3, since the communication state information is "333", it is indicated by "waiting" on all the tuning buttons 4a-6a.

The manager of the management room can input, to the input control means 22, channel selection information designating either of the channel selection buttons 4a to 6a by using an input device 21 such as a mouse or a keyboard.

4 is a flowchart showing the operation of the display control means 20 of FIG. The display control means 20 performs the process shown in FIG. 4 periodically (for example, every 200 milliseconds), and displays the display contents of the driving status display area 25 and the tuning button display area 26 of FIG. Update

In the operation shown in Fig. 4, first, it is checked whether or not there is received data from the second communication means 17 in the first buffer (step S1). If there is no received data in the first buffer, it is checked whether or not there is received data from the driving status data communication means 18 in the second buffer (step S4). If no buffer exists in any of the buffers, the process ends.

When data has been written to the first buffer, the display contents of the tuning button display area 26 are updated (step S2). For example, when communication state information "233" is written in the first buffer, the display control means 20 indicates that the communication symbol of unit A is "2", the communication symbol of unit B and unit C is "3". On the basis of the conversion table in Fig. 2, the display contents of the channel selection display area 26 are displayed as "A" call, "B" waiting, "C" waiting. When the display contents are updated, the first buffer is initialized (step S3) to confirm the presence or absence of received data in the second buffer (step S4).

When data is written in the second buffer, the display contents of the driving status display area 25 are updated (step S5), the second buffer is initialized (step S6), and the processing ends.

5 is a flowchart showing the operation of the input control means 22 of FIG. This processing flow starts as a trigger for selecting which of the tuning buttons 4a to 6a is selected using the input device 21. When any one of the tuning buttons 4a to 6a is selected, it is determined whether the display of the selected tuning buttons 4a to 6a is "waiting" or "calling" (step S11).

When the display of the selected tuning buttons 4a to 6a is "waiting" or "calling", the input control means 22 determines that the manager wishes to start a call with the passenger, and this tuning button 4a The display of ˜6a) is changed to “in a call” (step S12). In addition, when the display of the selected tuning buttons 4a to 6a is "calling", the input control means 22 determines that the manager wishes to terminate the call with the passenger, and the tuning buttons 4a to 6a are selected. The display is changed to "waiting" (step S13).

After that, the display contents of the changed tuning buttons 4a to 6a are transmitted to the second communication means 17 as tuning information (step S14). Tuning information is created based on the conversion table shown in FIG. For example, if the selected state of the A and C units is "waiting" and the selected state of the B unit is "calling", the tuning information is set to "313" using a communication symbol.

When the second communication means 17 receives the channel selection information from the input control means 22, it transmits the channel selection information to the first communication means 10 immediately. The first communication means 10 inputs the received channel selection information into the line selection means 11. The line selecting means 11 turns on / off the line connection between the handset 15 and the intercom magnetic apparatuses 4 to 6 in accordance with the inputted channel selection information.

For example, when the channel selection information is "313", the line selecting means 11 determines that the communication symbol indicating "in a call" is assigned to the B unit, and is connected to the interphone magnetic device 5 of the B unit. The audio cable 13 and the audio cable 24 connected to the receiver 15 are connected. In this way, the passenger in the cage | basket | car 2 of Unit B and the manager of the management room can be made.

As described above, in the elevator monitoring system of the first embodiment, the intercom main device 7 and the travel monitoring device 8 can communicate with each other. In addition, the driving monitoring apparatus 8 displays the communication status of the interphone magnetic apparatus 4 to 6 based on the communication status of the intercom magnetic apparatus 4 to 6 based on the communication status information of the interphone magnetic apparatus 4 to 6 received from the intercom main apparatus 7. It is possible to display on the monitor 19 together. In addition, the driving monitoring apparatus 8 is capable of inputting channel selection information for selecting the interphone magnetic devices 4 to 6 to communicate with. On the other hand, the interphone main device 7 is capable of transmitting communication status information to the driving monitoring apparatus 8 and establishes a connection state with the intercom magnetic apparatuses 4 to 6 based on the station selection information received from the driving monitoring apparatus 8. It becomes switchable.

Therefore, the manager can make an intercom call with the passengers in the desired cars 1 to 3 while monitoring the operating status of the elevator while being in front of the driving monitoring apparatus 8. Thereby, even when an emergency arises, the manager can make an interphone call with the passengers in the cage | basket | car 1-3 quickly.

Embodiment 3.

Next, FIG. 9 is a block diagram which shows the elevator monitoring system by Embodiment 3 of this invention. In the drawing, the display control means 20 periodically switches the images photographed by the surveillance cameras 31 to 33 based on the image data and displays them sequentially on the monitor 19. In addition, the display control means 20 receives the channel selection information from the input control means 22 and monitors the image in the cars 1 to 3 corresponding to the interphone magnetic devices 4 to 6 selected by the input device 21. (19) is selectively displayed. The other configuration is the same as that of the second embodiment.

FIG. 10 is a front view illustrating an example of display contents of the monitor 19 of FIG. 9. In the video display area 38, the normal display area 38a which periodically switches and displays the images in the cars of all the cars 1 to 3 and the inside of the car of the cars selected from the cars 1 to 3 are displayed. A selection display area 38b for continuously displaying the image is included. The selected car is a car corresponding to a plane whose display of the tuning buttons 4a to 6a is "in a call", that is, a car in which a passenger who is making an interphone call with a manager.

In the display control means 20, a correspondence table between the surveillance cameras 31 to 33 and the expiratory name as shown in Fig. 11 is set in advance. The camera ID is a number uniquely assigned to all the surveillance cameras 31 to 33. The breathing name is a sequence of video data input from the video data communication means 37 to the display control means 20. In the example of FIG. 10, video data is input to the display control means 20 in the order of the A-expiration, the B-expiration, and the C-expiration.

The display control means 20 operates according to the normal processing flow (FIG. 12) regarding display other than the selection display area 38b, and the selection display processing flow regarding the display of the selection display area 38b.

First, FIG. 12 is a flowchart showing the operation by the normal processing flow of the display control means 20 of FIG. The display control means 20 periodically performs the operation shown in FIG. In addition, among the operation | movement of the display control means 20 of Embodiment 3, operation | movement (step S1-step S6) regarding the driving | running situation display area | region 25 and the tuning-button display area 26 is carried out with Embodiment 1 (FIG. 4). same.

The display control means 20 causes the normal display area 38a to display an image based on the video data corresponding to the camera ID after the operation on the tuning button display area 26 (step S8). In other words, by using the correspondence table of Fig. 11, an exhalation name corresponding to the camera ID is acquired, and an image in the elevator compartment based on the acquired exhalation name and the image data having the exhalation name is displayed on the normal display area 38a. Let's do it.

After that, the camera ID is updated (step S9). That is, according to the correspondence table of FIG. 11, when the camera ID before update was "1", when the camera ID before update was "2", it was "3", and the camera ID before update was "3". If it is, the camera ID is updated to "1". Therefore, when the operation of FIG. 13 is executed every 200 milliseconds, for example, the image displayed on the normal display area 38a is also converted every 200 milliseconds.

Next, FIG. 13 is a flowchart showing the operation of the input control means 22 of FIG. This processing flow is started as a trigger to select any one of the tuning buttons 4a to 6a using the input device 21. In addition, the operation (step S11-step S14) regarding display switching of channel selection buttons 4a-6a, and channel selection information transmission is the same as that of Embodiment 1 (FIG. 5).

When the display of the selected station buttons 4a to 6a is "on call" (step S12), the communication symbol "1" and this unit name are displayed using the conversion table of FIG. It sends to a process flow (step S15). In addition, when the display of the selected station buttons 4a to 6a is set to "waiting", the communication symbol "3" and this call group name are sent to the selection display processing flow of the display control means 20. FIG.

Next, the selection display processing flow of the display control means 20 will be described. The selection display processing flow is executed periodically. When the communication symbol "1" is received from the input control means 22, the video data corresponding to this unit name is acquired from the third buffer of the display control means 20, and the video based on the acquired video data The breathing name is displayed in the selection display area 38b. In addition, when the communication symbol "3" is received from the input control means 22, a blue-back image is displayed on the selection display area 38b. That is, when the interphone call is not being made, the video in the car is not displayed in the selection display area 38b.

In such an elevator monitoring system, since the images in the plurality of cars 1 to 3 are sequentially displayed on the display area 38a in sequence, even when a large number of the monitoring cameras 31 to 33 are connected to each other, The inside of the car 1 to 3 can be monitored by the image of a size. In addition, since the image in the car of the selected car is displayed on the selection display area 38b, the intercom call can be made with the passenger while monitoring the car in which the passenger in the intercom call is riding with a larger image.

In addition, in Embodiment 3, although the normal display area 38a was made into one, you may provide a some normal display area or may divide into the inside of a normal display area in multiple numbers. For example, when a large number of surveillance cameras are connected, the surveillance cameras may be divided into a plurality of blocks, and the images may be sequentially displayed in the corresponding normal display area while switching images by the surveillance cameras in the blocks.

In addition, at least a part of the screen of the monitor 19 of the first to third embodiments may be configured by using a touch panel, for example, to make contact with the screen, thereby enabling input of presetting information.

Embodiment 7.

Next, FIG. 19 is a block diagram which shows the elevator monitoring system by Embodiment 7 of this invention. In the figure, a speaker (main device side speaker) 42 is provided in the interphone main device 7.

When the communication status information transmitted from the first communication means 10 to the second communication means 17 includes a communication symbol meaning "calling", the first communication means 10 uses the second communication means ( 17, a ringing signal is output to the speaker 42 according to the validity of the communication with the speaker. In addition, when the channel selection information received from the second communication means 17 does not include a communication symbol meaning "calling", the first communication means 10 communicates with the second communication means 17. According to the validity, the ringing tone signal is output to the speaker 42.

The first and second communication means (10, 17) transmits and receives a confirmation signal for confirming the validity of the communication between each other, and selects the speaker (41, 42) to make a ring tone (calling sound) according to the reception status of the confirmation signal do. The confirmation signal is assigned a unique communication symbol so as not to be confused with the communication status information and the station information.

For example, as the confirmation signal, the OxFF signal is output in a T second period from the first communication means 10, and the OxFE signal is output in a T second period from the second communication means 17. Therefore, when the communication is normal (valid), if the gap of the time required for communication is ignored, the OxFE signal is received in the first communication means 10 in a T second period, and the OxFF signal is received in the second communication means 17. It is received every T seconds.

Here, when the reception interval of the OxFE signal in the first communication means 10 is set to T1 seconds, an abnormality occurs in the communication between the first and second communication means 10, 17 when the T1 second exceeds T seconds. You can think of it. In the seventh embodiment, the threshold value TH for determining whether or not an abnormality has occurred in communication is set to TH = 3 × T.

Based on such a premise, the first communication means 10 determines that an abnormality has occurred in communication when T1> TH, and transmits an "ON" signal to the speaker 42 as a speaker control signal. On the other hand, when T1? TH, it is determined that communication is normal, and the first communication means 10 transmits an "OFF" signal to the speaker 42 as a speaker control signal.

If the reception interval of the OxFF signal in the second communication means 17 is set to T2 seconds, the second communication means 17 determines that an abnormality has occurred in communication when T2> TH, and thus the speaker 41 Transmits an "OFF" signal as a speaker control signal. On the other hand, when T2? TH, the communication is judged to be normal, and the second communication means 17 transmits an "ON" signal to the speaker 41 as a speaker control signal.

When the latest speaker control signal received is the "OFF" signal (communication state is normal), the speaker 42 of the interphone main unit 7 ignores the ringing signal and the ringing signal and always stops the ringing. do. In addition, when the latest speaker control signal received is an "ON" signal (communication state abnormal), the speaker 42 rings or sounds the ringing in accordance with the ringing tone signal and the ringing tone signal in the same manner as in the first embodiment. Determine.

When the latest speaker control signal received is the "OFF" signal (communication state abnormal), the speaker 41 of the driving monitoring device 8 ignores the ringing signal and the ringing signal and always stops ringing. do. When the latest speaker control signal received is the "ON" signal (communication state is normal), the speaker 41 performs the ringing or the ringing of the ringing in accordance with the ringing signal and the ringing signal, as in the first embodiment. Decide

As described above, in the elevator monitoring system of the seventh embodiment, a speaker for exchanging a signal for confirming the validity of the communication between the first and second communication means 10 and 17, and ringing a ring according to the validity of the communication ( Since 41 and 42 are selected, when the communication state is normal, the manager can ring only the speaker 41 of the driving monitoring apparatus 8 that is assumed to be nearby, so that the noise of the ringing can be reduced. In addition, even when an abnormality occurs in the communication state, the speaker 42 of the intercom main device 7 rings, so that the caller from the intercom magnetic devices 4 to 6 can be notified to the manager or the like.
