The management server computer 130 monitors the operation of the elevator 101 via the remote monitoring support device 120.

The management server computer 130 is installed in a remote location away from the location where the elevator 101 to be monitored is installed, which is different from the location where the elevator 101 to be monitored is installed. Specifically, the management server computer 130 can be installed in, for example, a maintenance management company 150 that is in charge of maintenance management of the elevator 101.

The telephone 140 is installed, for example, in the maintenance management company 150 in which the management server computer 130 is installed. By installing the management server computer 130 and the telephone 140 in the maintenance management company 150, a person in the basket 102 of the elevator 101 and an operator of the maintenance management company 150 can directly talk to each other.

The elevator 101 is installed in a multi-story building or the like, and includes a basket (car) 102 for carrying people and goods. One basket 102 is provided for each elevator 101. The basket 102 is provided in a hoistway (not shown) that penetrates each floor in the building along the vertical direction. The elevator 101 can be realized by, for example, a rope type (traction type) elevator.

The elevator 101 that can be monitored by the remote monitoring system 100 of the embodiment according to the present invention is not limited to the rope type elevator. In the remote monitoring system 100 of the embodiment according to the present invention, for example, the hydraulic elevator 101 may be monitored in place of the rope type elevator 101 or in addition to the rope type elevator 101.

The basket 102 is provided with an operation panel 102a provided with operation buttons including a destination floor button, a door open / close button, and a display for displaying the floor on which the basket 102 is located. The operation panel 102a provided in the basket 102 includes a control board for the operation panel 102a, and is connected to the control board 110 via the control board for the operation panel 102a.

Further, the basket 102 is provided with an intercom terminal device 102b. The terminal device 102b of the intercom includes a call button, a microphone, and a speaker (all of which are not shown). The terminal device 102b of the intercom is connected to the remote monitoring support device 120.

The above-mentioned operation button includes an emergency call button 102c that is operated at the time of a call with an external manager or operator of the basket 102. When the emergency call button 102c is operated, the control board for the operation panel 102a sends a signal indicating that the emergency call button 102c is operated to the outside of the terminal device 102b of the intercom (in this embodiment, remote control). Output to the monitoring support device 120).

In this embodiment, the operation of the call request according to the present invention can be realized by operating the emergency call button 102c. As a result, the remote monitoring system 100 can make a call to a predetermined call destination when the call request of the intercom provided in the basket 102 of the elevator 101 is operated.

The hoistway is provided with a drive mechanism 104 involved in the raising and lowering operation of the basket 102. The drive mechanism 104 can be provided, for example, at the upper part of the hoistway. The drive mechanism 104 is composed of a hoist, a pulley, a rope 104a, a counterweight 104b, and the like. The drive mechanism 104 further includes an electromagnetic brake, a speed governor, and the like (all of which are not shown).

Since the drive mechanism 104 can be easily realized by using a known technique, the description thereof will be omitted. The drive mechanism 104 is not limited to the one provided at the upper part of the hoistway. For example, in the case of the hydraulic elevator 101, the drive mechanism 104 may be provided at the bottom (pit) in the hoistway.

The basket 102 is connected to one end of the rope 104a, and the counterweight 104b is connected to the other end of the rope 104a. In the rope type elevator 101, the hoisting machine is driven in a state where the rope 104a in which the basket 102 and the counterweight 104b are connected to both ends is hung on the pulley and the hoisting machine in a hanging manner, and between the rope 104a and the hoisting machine. The basket 102 is moved up and down by using the frictional force (traction) of. The hoistway is provided with a guide rail (not shown) that guides the elevating position of the basket 102.

Doors 105a and 102d are provided at positions (landings) 105 and baskets 102 corresponding to each floor in the hoistway, respectively. The basket 102 is provided with a motor (not shown) for opening and closing the door 102d provided in the basket 102 and the door 105a provided in the landing 105. The motor for opening and closing the doors 105a and 102d is connected to the control board 110.

The control board 110 outputs a travel start signal, for example, when the basket 102 starts traveling. The control board 110 outputs, for example, a travel stop signal when the traveling basket 102 stops traveling. The travel start signal can be realized, for example, by a dedicated signal for notifying that the basket 102 has started traveling. Alternatively, the travel start signal and the travel stop signal may be realized by, for example, a drive signal output to the hoist.

The door 105a provided at the landing 105 is locked by a device called an interlock or the like. When the motor is driven while the elevator 101 has arrived at the stop floor, the drive mechanism portion of the door 102d provided in the basket 102 and the interlock are engaged with each other to release the lock by the interlock, and the door 102d provided in the basket 102 is released. And the door 105a provided at the landing 105 opens and closes in conjunction with each other. As a result, the door 105a provided at the landing 105 is closed when the basket 102 is not stopped at the stop position on each floor.

The hoistway may be provided with a sensor whose output changes according to the position of the basket 102. The sensor can be realized by, for example, a proximity sensor or a photoelectric sensor. For example, in the case of realizing a sensor provided in the hoistway by a proximity sensor, a proximity sensor is provided at a position corresponding to the position of the basket 102 in a stopped state on each floor, and a metal detection piece is placed in the basket 102. Provide. In this case, the position of the basket 102 can be specified based on the output signal from the proximity sensor that changes as the detection piece approaches the proximity sensor.

Further, for example, when the sensor provided in the hoistway is realized by the photoelectric sensor, the photoelectric sensor is placed at a position corresponding to the position of the basket 102 stopped on each floor, as in the case of the proximity sensor described above. A piece for detection is provided in the basket 102. The detection piece is formed by using a material that blocks (or reflects) the light emitted by the photoelectric sensor. In this case, the position of the basket 102 can be specified based on the output signal from the photoelectric sensor that changes as the detection piece blocks (or reflects) the optical axis of the photoelectric sensor.

The elevator 101 includes a door opening / closing sensor (not shown) that detects the opening / closing of the doors 102d and 105a. The output of the door open / close sensor changes depending on whether the doors 102d and 105a are in the open state or the closed state. The door open / close sensor can be realized by, for example, a micro switch or a photoelectric sensor. The door open / close sensor is connected to the control board 110 via wiring, and the signal output from the door open / close sensor is input to the control board 110 via the wiring.

Each landing 105 is provided with an operation panel 105b provided with a landing call button (not shown) and a display for displaying the floor on which the basket 102 is located. The operation panel 105b provided in each landing 105 is provided with a control board for the operation panel 105b, and is connected to the control board 110 via the control board for the operation panel 105b.

The remote monitoring support device 120 can be attached to, for example, a housing for accommodating the control board 110 of the elevator 101, a wall of a hoistway, or the like. The remote monitoring support device 120 includes a main control board 121 and a voice communication board 122. The main control board 121 is connected to the control board 110. Further, the main control board 121 is connected to the management server computer 130 via a network 160 such as the Internet. By connecting the main control board 121 and the management server computer 130 via the Internet instead of the public voice network 170 such as a telephone line, it is possible to prevent a delay in grasping the status of the elevator 101 due to a flat tire on the telephone line in an emergency. And you can take prompt action.

The voice communication board 122 is connected to the terminal device 102b of the intercom and the public voice network 170. Specifically, the voice communication board 122 can be realized by, for example, a PHS (Personal Handy-phone System) board. The public voice network 170 includes a fixed telephone network (public switched telephone network) and a mobile telephone network. The public voice network 170 is composed of a plurality of exchanges (not shown), such as a subscriber line exchange for accommodating telephone lines, a relay exchange for bundling subscriber line exchanges, and a barrier exchange for connecting to the telephone networks of other companies. There is. Since the public voice network 170 is a known technique, the description thereof will be omitted.

The main control board 121 may perform communication using the PHS board included in the voice communication board 122. In this case, the remote monitoring support device 120 uses the PHS board for voice communication as well as data communication. Since the installation location of the elevator 101 is fixed, it is possible to ensure the quality of communication and reduce the cost of communication by performing communication using PHS.

The management server computer 130 can be realized by a computer device such as a personal computer. A terminal device 131 for operation may be connected to the management server computer 130. The management server computer 130 and the terminal device 131 for operation may be installed in the same place or may be installed in different places.

The terminal device 131 for operation may be one unit or a plurality of units. The terminal device 131 for operation can be realized by, for example, an input device such as a keyboard or a mouse, or a computer device such as a personal computer provided with a display or the like. Further, a printer (not shown) for outputting a report or the like describing the state of the elevator 101 may be connected to the terminal device 131 for operation.

In addition to the management server computer 130 and the telephone 140, the maintenance management company 150 can install a PBX (Private Branch eXchange, see reference numeral 205 in FIG. 2). The telephone 140 is connected to the public voice network 170 via the PBX. In the remote monitoring system 100, the telephone 140 may be directly connected to the public voice network 170 without providing the PBX.

(Hardware configuration of remote monitoring system 100)
Next, the hardware configuration of the remote monitoring support device 120 constituting the remote monitoring system 100 of the embodiment according to the present invention will be described. FIG. 2 is an explanatory diagram showing a hardware configuration of a remote monitoring support device 120 constituting the remote monitoring system 100 according to the embodiment of the present invention.

In FIG. 2, the control board 110 controls the operation operation of the elevator 101 by driving and controlling each part constituting the elevator 101. The control board 110 outputs a control signal to each part of the elevator 101, and controls the operation operation of the elevator 101 based on the signal output from each part.

Each time the control board for the operation panel 102a described above receives an input operation for an operation button by a user of the elevator 101 or the like, a call signal corresponding to the input operation is generated, and the generated call signal is output to the control board 110. To do. The control board 110 controls the operation of the elevator 101 by outputting a control signal for driving and controlling the drive mechanism 104, for example, based on a call signal output from the control board for the operation panel 102a.

Specifically, the control board 110 generates, for example, a control signal for the hoisting machine based on a call signal output from the control board for the operation panel 102a, and hoists the generated control signal. Output to the machine. As a result, the hoisting machine is rotationally driven in the direction of raising or lowering the basket 102. The hoisting machine is controlled by using, for example, an inverter, and is driven and controlled by the control board 110 so as to stop the rotation on the floor where the basket 102 is stopped.

Each time the control board 110 outputs a control signal to the hoisting machine, the control board 110 acquires the rotation speed of the hoisting machine and each motor that operates according to the control signal. The rotation speed of the hoisting machine and each motor can be obtained by using, for example, an encoder. As a result, the control board 110 can determine whether or not the hoisting machine has operated normally according to the control signal output to the hoisting machine.

Specifically, the control board 110 is used for control, for example, to operate the brake so as to stop the basket 102 on a predetermined floor based on a call signal output from the control board for the operation panel 102a. A signal is generated, and the generated control signal is output to the brake. The brake operates so as to stop the raising and lowering operation of the basket 102 and stop the basket 102 on a predetermined floor according to the control signal output from the control board 110. As a result, the basket 102 can be stopped on a predetermined floor.

Each time the control board 110 outputs a control signal to the brake, the control board 110 acquires an output signal from the brake sensor whose output changes according to the operation of the brake. The brake sensor can be realized by, for example, a microswitch or a photoelectric sensor. As a result, the control board 110 can determine whether or not the brake has normally operated according to the control signal output to the brake.

Specifically, the control board 110 controls to open and close the doors 102d and 105a on the floor where the basket 102 is stopped by the brake, for example, based on the call signal output from the control board for the operation panel 102a. Signal is generated, and the generated control signal is output to the motor that opens and closes the door 102d of the basket 102 and the door 105a of the landing 105. As a result, the doors 102d and 105a can be opened and closed on the floor where the basket 102 is stopped. As described above, the motor that opens and closes the door 105a is locked by a device called an interlock or the like, and therefore does not operate if the door 105a is not completely closed.

The control board 110 acquires an output signal from the door opening / closing sensor each time a control signal is output to the motor that opens / closes the doors 102d and 105a. Thereby, the control board 110 can determine whether or not the doors 102d and 105a have normally operated according to the control signal output to the motor that opens and closes the corresponding doors 102d and 105a.

Further, the control board 110 outputs a control signal including a floor signal indicating the floor on which the basket 102 is located to the control board for the operation panel 102a, for example. The floor on which the basket 102 is located can be identified, for example, based on an output signal from a sensor (not shown) provided for each floor in the hoistway. When the control board for the operation panel 102a receives a control signal including a floor signal, the control board controls the display based on the received control signal, and controls the display on the floor where the basket 102 is located and the moving direction (ascending). Or descending) etc. are displayed.

The control board 110 outputs a control signal including a floor signal to the control board for the operation panel 102a and the control board for the operation panel 105b, for example, every time the position of the basket 102 is changed. Alternatively, the control board 110 periodically outputs a control signal including a floor signal to the control board for the operation panel 102a and the control board for the operation panel 105b regardless of the position of the basket 102, for example. It may be something to do.

Similar to the control board for the operation panel 102a, the control board for the operation panel 105b generates a call signal corresponding to the input operation each time an input operation for the landing call button by a user of the elevator 101 or the like is received. The generated call signal is output to the control board 110. When the call signal was output from the control board for the operation panel 105b, the control board 110 was output from the control board for the operation panel 105b in the same manner as when the signal was output from the control board for the operation panel 102a. The operation of the elevator 101 is controlled by generating various control signals based on the signals and outputting the generated control signals to the corresponding parts.

Each time the control board 110 raises or lowers the basket 102 in response to a signal output from the operation panel 102a or the operation panel 105b, the control board 110 outputs an activation signal indicating that each part has been activated in order to raise or lower the basket 102. .. For example, when the control board 110 moves from the first floor to the second floor, the control board 110 outputs a start signal once. Further, for example, when the control board 110 moves from the first floor to the fifth floor without stopping in the middle, the control board 110 outputs a start signal once. Further, for example, when the control board 110 moves from the first floor to the fifth floor after stopping at the third floor on the way (opening / closing the door), the control board 110 outputs a start signal twice.

The control board 110 may calculate the traveling distance and traveling time of the basket 102 each time the basket 102 is moved up and down. The mileage of the basket 102 can be calculated based on, for example, the number of activations. Further, the traveling time of the basket 102 can be calculated based on, for example, the above-mentioned floor signal. Specifically, for example, when a call operation is received from the operation panel 105b of the platform 105 on the 4th floor while the basket 102 is on the 1st floor, the basket 102 moves on the 3rd floor from the 1st floor to the 4th floor. To do.

The control board 110 includes a memory (not shown), and each time a start signal is output, the control board 110 stores the number of times the start signal is output, that is, the number of start times. The control board 110 may store in the memory the history of the operation operation of each part driven during the raising / lowering operation of the basket 102 and the opening / closing operation of the doors 105a and 102d in place of the number of activations or in addition to the number of activations. Specifically, the control board 110 relates to, for example, the number of activations, the mileage of the basket 102, the traveling time of the basket 102, the number of operations of various relays operated during the raising / lowering operation of the basket 102 and the opening / closing operations of the doors 105a and 102d. The information may be stored in the memory as a history of operation operations.

Further, the control board 110 determines whether the doors 102d and 105a are in the open state or the closed state based on the output value of the door open / close sensor. The control board 110 outputs a control signal for opening and closing the doors 102d and 105a based on the control signal for opening and closing the doors 102d and 105a and the output value of the door open / close sensor. , It can be determined whether or not the doors 102d and 105a are actually opened and closed.

Further, when the operation mode of the elevator 101 changes, the control board 110 outputs a signal indicating that the operation mode has been switched. Specifically, the control board 110 externally informs that, for example, when the operation mode of the elevator 101 is switched from the normal operation mode to an operation mode other than the normal operation mode, the operation mode is switched. It outputs a signal to notify or a signal to notify the operation mode after switching (the operation mode is other than the normal operation mode). Further, specifically, the control board 110 indicates that, for example, when the operation mode of the elevator 101 is switched from an operation mode other than the normal operation mode to a normal operation mode, the operation mode is switched. It outputs (issues) a signal to notify the outside or a signal (signal for issuing) notifying the operation mode (normal operation mode) after switching.

Further, when the elevator 101 detects a failure, the control board 110 outputs (issues) a signal (signal for issuing a report) notifying the occurrence of the failure. Specifically, although the control board 110 outputs, for example, a control signal for opening / closing the doors 105a and 102d, the corresponding doors 105a and 102d do not operate based on the output value of the door opening / closing sensor. When this is detected, a signal (signal for issuing a notification) notifying that a failure has occurred in the corresponding doors 105a and 102d in the elevator 101 is output.

The control board 110 can output (report) a signal for issuing a report to the outside of the control board 110, for example, via a wiring connecting the control board 110 and an external device. More specifically, in the control board 110, for example, the wiring connecting the control board 110 and the external device sends a signal for alarm to the outside of the control board 110 via a contact connected to the control board 110. Can be output (reported) to.

The control board 110 may output a signal for issuing an alarm to the outside of the control board 110, for example, via a terminal provided on the control board 110. Specifically, the control board 110 can output a signal for issuing a notification to the outside of the control board 110, for example, via a communication terminal that communicates with an external device of the elevator 101. .. Alternatively, specifically, the board 110 is provided on the control board 110, for example, via a terminal (hereinafter referred to as “maintenance / inspection terminal”) to which a terminal device for diagnosis can be connected to the control board 110. Therefore, the alarm signal may be output to the outside of the control board 110.

When the call button is operated, the terminal device 102b of the intercom outputs a call signal indicating that the operation has been performed to the remote monitoring support device 120. When the call signal output from the terminal device 102b of the intercom is input to the voice communication board 122, the remote monitoring support device 120 sends a call signal to the telephone 140 via the public voice network 170 or PBX 205. As a result, voice communication (call) can be performed between the terminal device 102b of the intercom and the telephone 140.

The terminal device 102b of the intercom remotely monitors the voice signal input to the microphone in a state where the connection between the remote monitoring support device 120 (voice communication board 122) and the telephone 140 installed in the maintenance management company 150 is established. Output to the support device 120. Further, the intercom terminal device 102b transmits the voice signal output from the remote monitoring support device 120 via the speaker in a state where the connection between the remote monitoring support device 120 (voice communication board 122) and the telephone 140 is established. Output. As a result, the user in the basket 102 can have a direct conversation (direct talk) with the operator of the telephone 140 at the maintenance management company 150 via the terminal device 102b of the intercom.

The remote monitoring support device 120 acquires signals (control signals) output from the control board 110 to each unit included in the elevator 101, and generates and generates notification information based on the acquired control signals.

May be provided. In such a remote monitoring support device 120, for example, the connection terminal and the terminal for maintenance and inspection can be connected by inserting and fitting the connection terminal into the terminal for maintenance and inspection.

Further, the remote monitoring support device 120 receives various instruction signals transmitted from the management server computer 130 via the communication I / F 204. For example, when the maintenance management company 150 accepts an input operation to the management server computer 130 by the operator, the management server computer 130 outputs an instruction signal to the remote monitoring support device 120.

Specifically, the management server computer 130 receives an instruction signal (transmission of notification information) instructing, for example, transmission of notification information regarding the result of the diagnostic operation executed in the elevator 101 in response to the input operation received by the management server computer 130. Instructions) are sent. In this case, the management server computer 130 transmits an instruction to execute the diagnostic operation to the elevator 101 in addition to the instruction to transmit the notification information.

In the diagnostic operation, the control board 110 causes each part of the elevator 101 to output a signal for operating each part in a predetermined order, and a signal indicating whether or not each part operates normally according to the output signal. Is realized by outputting from the control board 110. The management server computer 130 may output the next diagnostic instruction periodically, that is, when a predetermined time has elapsed after outputting the diagnostic instruction (every predetermined period such as every month).

The same response information as described above may be generated, and the generated response information may be output to the management server computer 130. As described above, the remote monitoring system 100 of the embodiment according to the present invention can perform not only remote diagnosis of the elevator 101 but also remote monitoring of the elevator 101.

The remote monitoring support device 120 calls a predetermined call destination when the emergency call button 102c provided in the basket 102 of the elevator 101 is operated. Specifically, when the remote monitoring support device 120 receives an input of a signal indicating that the emergency call button 102c has been operated, it outputs a transmission signal to the public voice network 170 (subscriber line exchange). Then, when the remote monitoring support device 120 receives the dial tone transmitted from the subscriber line exchange in response to the dial tone, the remote monitoring support device 120 receives a telephone number assigned to the telephone 140 installed in the maintenance management company 150 or the like, which is set in advance. The push signal corresponding to the above is output to the subscriber line exchange. As a result, the telephone 140 is called through the plurality of exchanges described above, and a communication line is connected between the telephone 140 and the terminal device 102b of the intercom.

The management server computer 130 generates report information based on the response information transmitted from the remote monitoring support device 120 in response to various instruction signals transmitted to the remote monitoring support device 120.

When the operation terminal device 131 receives the print information, the operation terminal device 131 can issue a report by driving and controlling the printer connected to the operation terminal device 131.

(Functional configuration of remote monitoring system 100)
Next, the functional configuration of the remote monitoring system 100 according to the embodiment of the present invention will be described. FIG. 3 is a block diagram showing a functional configuration of the remote monitoring support device 120 constituting the remote monitoring system 100 according to the embodiment of the present invention.

(Functional configuration of remote monitoring support device 120)
In FIG. 3, each function of the remote monitoring support device 120 constituting the remote monitoring system 100 of the embodiment according to the present invention includes a specific unit 301, an open / close determination unit 302, a timekeeping unit 303, and an elevating determination unit 304. , The call determination unit 305, the operation determination unit 306, the call control unit 307, and the call determination unit 308.

When the basket 102 is stopped, the identification unit 301 identifies the position (stop position) of the basket 102. The specific unit 301 can be realized by, for example, the main control board 121. The stop position of the basket 102 can be specified based on, for example, the position where the basket 102 started moving immediately before, the traveling amount of the basket 102, the traveling direction of the basket 102 immediately before stopping, and the like.

The position where the basket 102 starts moving immediately before can be stored in the memory 203 every time the basket 102 moves and stops, and can be specified based on the information stored in the memory 203. The traveling amount of the basket 102 can be specified, for example, based on the driving amount of the hoisting machine. The driving amount of the hoisting machine is, for example, the number of revolutions of the hoisting machine, the time from the start to the stop of driving the hoisting machine, and the traveling direction of the basket 102 immediately before the hoisting machine is stopped. It can be specified based on the driving direction immediately before stopping.

When the basket 102 is stopped, the open / close determination unit 302 determines whether or not the stop position is a position where the door 102d of the basket 102 can be opened / closed based on the stop position of the basket 102 specified by the specific unit 301. .. The open / close determination unit 302 determines, for example, whether or not the sensor corresponding to any floor has detected the basket 102 based on the output signal from the sensor provided in the hoistway, thereby determining the basket 102. It is possible to determine whether or not the stop position of the car 102 is a position where the door 102d of the basket 102 can be opened and closed. The open / close determination unit 302 can be realized by, for example, the main control board 121.

The timekeeping unit 303 measures the elapsed time from the stop of the basket 102 when the stop position of the basket 102 specified by the specific unit 301 is not a position where the door 102d of the basket 102 can be opened and closed. Based on the determination result of the open / close determination unit 302, the timekeeping unit 303 determines that the stop position of the basket 102 specified by the specific unit 301 is not a position where the door 102d of the basket 102 can be opened / closed. Each time the basket 102 is stopped immediately before, the elapsed time is counted. The timekeeping unit 303 can be realized by, for example, the main control board 121.

The ascending / descending determination unit 304 determines whether or not the basket 102 has resumed ascending or descending. The ascending / descending determination unit 304 determines, for example, whether or not the basket 102 has resumed ascending or descending based on whether or not the hoisting machine is driven. The ascending / descending determination unit 304 determines whether or not the hoisting machine is driven during the time counting by the timing unit 303, that is, when the basket 102 is stopped at a position where the door 102d cannot be opened / closed. Therefore, it may be determined whether or not the basket 102 has resumed ascending or descending. The ascending / descending determination unit 304 can be realized by, for example, the main control board 121.

The call determination unit 305 determines whether or not a call by an intercom (hereinafter, “intercom call”) is in progress. The call determination unit 305 can determine whether or not an intercom call is in progress by, for example, determining whether or not a telephone line is connected between the telephone 140 and the terminal device 102b of the intercom. The call determination unit 305 can be realized by, for example, the main control board 121.

The call determination unit 305 may determine whether or not the user of the elevator 101 and the operator of the maintenance management company 150 are actually making an intercom call via the intercom. In this case, the call determination unit 305 continues to have no voice input / output in the terminal device 102b for a predetermined time or longer in a situation where a call line is connected between the telephone 140 and the terminal device 102b of the intercom, for example. By determining whether or not the call has been made, it is possible to determine whether or not an intercom call is in progress.

Alternatively, in this case, the call determination unit 305 is in a state where, for example, a telephone line is connected between the telephone 140 and the terminal device 102b of the intercom, and there is no voice input to the terminal device 102b for a predetermined time or longer. It may be determined whether or not an intercom call is in progress by determining whether or not the call has continued. As a result, even when the basket 102 is unmanned, a telephone line is connected between the telephone 140 and the terminal device 102b of the intercom, and the operator talks to the inside of the basket 102, the user can use the basket 102. If there is no response, it is determined that the intercom call is not in progress, and the connected line can be disconnected.

As a result, it is possible to prevent a situation in which it is difficult to connect a line with a user who desires an intercom call with high urgency due to the non-urgent line being connected to the telephone 140. As a result, the user can use the elevator 101 with peace of mind, and the reliability of the elevator 101 can be improved.

The operation determination unit 306 determines whether or not the emergency call button 102c is operated. The operation determination unit 306 determines whether or not the emergency call button 102c provided in the intercom terminal device 102b is operated, at least when the stop position of the basket 102 is not a position where the door 102d of the basket 102 can be opened and closed. Thereby, for example, it is possible to determine whether or not the emergency call button 102c is operated after the basket 102 is stopped at a position where the door 102d cannot be opened or closed, such as between the floors. The operation determination unit 306 determines, for example, whether or not a signal indicating that the emergency call button 102c has been operated has been output from the control board for the operation panel 102a. The operation determination unit 306 can be realized by, for example, the main control board 121.

When the elapsed time measured by the time counting unit 303 reaches a predetermined notification start time, the call control unit 307 controls the call unit 308 to start a call to the call destination. The call unit 308 can be realized by, for example, the voice communication board 122. The call control unit 307 can be realized by, for example, the main control board 121. The report start time is a time for determining whether or not to start a call for connecting the intercom to the telephone 140 installed in the maintenance management company 150, and the administrator of the remote monitoring system 100 or the like arbitrarily decides whether or not to start a call. Can be set.

When the elapsed time measured by the time counting unit 303 reaches a predetermined notification start time, the call control unit 307 determines the result of the operation determination unit 306 during the time measurement by the time counting unit 303, that is, the basket 102. A call to the call destination is started regardless of whether or not the emergency call button 102c is operated in a situation where the door 102d is stopped at a position where it cannot be opened and closed.

The call destination is specified by a preset telephone number. The preset telephone number can be realized, for example, by the telephone number assigned to the telephone 140 installed in the maintenance management company 150. As a result, when the basket 102 is stopped at a position where the door 102d cannot be opened and closed for a predetermined notification start time or longer, it is installed in the maintenance management company 150 regardless of the presence or absence of a user in the basket 102. A call is made to the telephone 140.

The call control unit 307 is based on the determination result of the call determination unit 304 when the basket 102 resumes ascending or descending before the elapsed time reaches the notification start time. If it is determined that the call is not in progress, the call may be canceled. Alternatively, the call control unit 307 determines the result of the call determination unit 305 when the basket 102 resumes ascending or descending before the elapsed time reaches the notification start time, based on the determination result of the elevating determination unit 304. Based on this, it is determined that the call is not in progress, and based on the determination result of the operation determination unit 306, the operation of the emergency call button 102c from the time when the basket 102 is stopped until the elapsed time reaches the report start time is performed. If it is determined that there is no call, the call may be stopped.

In this embodiment, the functions of the specific unit 301, the timekeeping unit 303, the open / close determination unit 302, the elevator determination unit 304, the call determination unit 305, the operation determination unit 306, the call control unit 307, and the call unit 308 are remotely monitored. Although it is realized by the support device 120, the functions of each of these parts may be realized by the control board 110 of the elevator 101. Alternatively, a remote monitoring support device may perform some of the functions of the specific unit 301, the timekeeping unit 303, the open / close determination unit 302, the elevating determination unit 304, the call determination unit 305, the operation determination unit 306, the call control unit 307, and the call unit 308. It may be realized by 120, and the remaining part may be realized by the control board 110.

(Processing procedure of remote monitoring support device 120)

In step S401, when the basket 102 of the elevator 101 is stopped (step S401: Yes), the stop position of the basket 102 is specified (step S402). In step S402, for example, as described above, it can be specified based on the position where the basket 102 starts moving immediately before, the traveling amount of the basket 102, the traveling direction of the basket 102 immediately before stopping, and the like.

Next, based on the stop position of the basket 102 specified in step S402, it is determined whether or not the stop position is a position where the door 102d of the basket 102 can be opened and closed (step S403). In step S403, when the stop position of the car 102 is open position the door 102d of the cage 102 (step S403: Yes), the series of processing is terminated.

In step S403, when the stop position of the basket 102 is not a position where the door 102d of the basket 102 can be opened and closed (step S403: No ), the elapsed time is started to be timed (step S404). In step S404, the elapsed time from the time when the basket 102 is stopped in step S401: Yes can be clocked. The elapsed time can be measured using, for example, memory 203 or the like.

Next, it is determined whether or not the emergency call button 102c has been operated after the basket 102 is stopped in step S401: Yes (step S405). In step S405, after the basket 102 is stopped in step S401: Yes, it is determined whether or not a signal indicating that the emergency call button 102c has been operated is output from the control board for the operation panel 102a. It can be determined whether or not the call button 102c has been operated.

In step S405, after the basket 102 is stopped in step S401: Yes, the emergency call button 102c is output when a signal indicating that the emergency call button 102c has been operated is output from the control board for the operation panel 102a. Judge that it has been operated. In step S405, if the emergency call button 102c is operated after the basket 102 is stopped in step S401: Yes and before the above-mentioned notification start time elapses (step S405: Yes), the process proceeds to step S413.

In step S405, when the emergency call button 102c is not operated after the basket 102 is stopped in step S401: Yes (step S405: No), the elapsed time when the time counting is started in step S404 is set to the above-mentioned notification start time. It is determined whether or not it has been reached (step S406).

In step S406, when the elapsed time has not reached the above-mentioned notification start time (step S406: No), it is determined whether or not the basket 102 stopped in step S401: Yes has resumed ascending or descending (step). S407). In step S407, for example, as described above, it is possible to determine whether or not the basket 102 has resumed ascending or descending based on the presence or absence of driving of the hoisting machine.

In step S407, if the basket 102 stopped in step S401: Yes has not resumed ascending or descending (step S407: No), the process returns to step S405. On the other hand, in step S407, when the basket 102 resumes ascending or descending (step S407: Yes), the series of processes shown in the flowchart of FIG. 4 is terminated. Then, the remote monitoring support device 120 starts the process shown in the flowchart of FIG. 4 and waits until the basket 102 is stopped next time. The control board 110 drives and controls the elevator 101 according to the control program of the elevator 101 regardless of the execution status of the process shown in the flowchart of FIG.

In step S406, when the emergency call button 102c is not operated after the basket 102 is stopped and the elapsed time reaches the notification start time without restarting the ascending or descending (step S406: Yes). Calling to the telephone 140 installed in the maintenance company 150 is started (step S408). Then, it is determined whether or not the basket 102 has resumed ascending or descending (step S409).

In step S409, when the basket 102 resumes ascending or descending (step S409: Yes), it is determined whether or not an intercom call is in progress (step S410). If the basket 102 resumes ascending or descending in step S409 after the call is started from the terminal device 102b side of the intercom in step S408 and before the line with the telephone 140 is connected, the process of connecting the line is continued. It remains as it is. In step S410, assuming a situation in which the process of connecting the line is continued in this way, or a situation in which the basket 102 resumes ascending or descending before determining that the line is connected, the intercom Determine if you are on a call.

Alternatively, in step S410, for example, as described above, whether or not the state in which there is no voice input / output in the terminal device 102b of the intercom to which the telephone line is connected to the telephone 140 continues for a predetermined time or longer. , It may be determined whether or not an intercom call is in progress. Alternatively, in step S410, for example, as described above, depending on whether or not the state in which no voice is input to the terminal device 102b of the intercom to which the telephone line is connected to the telephone 140 continues for a predetermined time or longer. It may be determined whether or not an intercom call is in progress.

In step S410, if an intercom call is in progress (step S410: Yes), the process proceeds to step S414. In step S410, when the intercom call is not in progress (step S410: No), the call is stopped (step S411), and the series of processes is terminated. In step S411, if a communication line is connected between the terminal device 102b of the intercom and the telephone 140, the call is stopped by disconnecting the line. Further, if the call is being made from the terminal device 102b of the intercom to the telephone 140, the call processing is stopped. Further, in step S410, for example, the time counting of the elapsed time is stopped, and the information related to the time counting of the elapsed time in the memory 203 is erased.

In step S409, when the basket 102 has not resumed ascending or descending (step S409: No), it is determined whether or not a telephone line is connected between the terminal device 102b of the intercom and the telephone 140 (step S412). .. In step S412, if the basket 102 has not resumed ascending or descending and the telephone line is not connected between the terminal device 102b of the intercom and the telephone 140 (step S412: No), the process returns to step S409. .. On the other hand, in step S412, if a telephone line is connected between the terminal device 102b of the intercom and the telephone 140 (step S412: Yes) before the basket 102 resumes ascending or descending, the process proceeds to step S414.

In step S405 described above, when the emergency call button 102c is operated after the basket 102 is stopped in step S401: Yes (step S405: Yes), a call process is performed (step S413). In step S413, for example, the voice communication board 122 is controlled by the main control board 121, and a push signal corresponding to the telephone number assigned to the telephone 140 is output to the subscriber line exchange to perform the call processing. ..

In the public voice network 170, a communication line is connected between the voice communication board 122 and the telephone 140 via an exchange including the subscriber line exchange of the telephone 140 in response to the push signal output to the subscriber line exchange. To do. As a result, the communication line between the terminal device 102 of the intercom and the telephone 140 is connected, and the conversation between the terminal device 102 of the intercom and the telephone 140 becomes possible.

In step S414, it is determined whether or not the line connected in step S413 is disconnected (step S414). In step S414, for example, it is determined by determining whether or not the operation of disconnecting the line has been performed on either the telephone 140 side or the terminal device 102b side of the intercom.

In step S414, for example, as described above, the intercom depends on whether or not the state in which there is no voice input / output in the terminal device 102b of the intercom to which the telephone line is connected to the telephone 140 continues for a predetermined time or longer. You may decide whether or not you are in a call. Alternatively, in step S410, for example, as described above, depending on whether or not the state in which no voice is input to the terminal device 102b of the intercom to which the telephone line is connected to the telephone 140 continues for a predetermined time or longer. It may be determined whether or not an intercom call is in progress. After that, it waits until the line is disconnected (step S414: No), and when the line is disconnected (step S414: Yes), a series of processes is terminated. In step S414: Yes, when the line is disconnected, a series of processes may be terminated after performing a process such as a disconnection process.

In the above-described embodiment, in steps S407 and S409, for example, the basket 102 is not limited to the same direction as the traveling direction of the basket 102 immediately before stopping in step S401: Yes, and the basket 102 is opposite to the traveling direction immediately before. It may be determined whether or not the vehicle has started traveling in the direction of. Specifically, for example, in an elevator 101 controlled to stop on the nearest floor in an emergency such as an earthquake having a predetermined seismic intensity or higher, the elevator 101 stopped while traveling from the second floor to the third floor, for example. If the stop position of the basket 102 is closer to the 3rd floor than the 2nd floor, the vehicle travels toward the 3rd floor (nearest floor).

In such an elevator 101, for example, when the basket 102 is stopped between the floors because an earthquake having a predetermined seismic intensity or higher is detected while traveling from the second floor to the third floor, the basket 102 resumes traveling. In that case, if the stop position of the basket 102 is closer to the second floor than the third floor, it is controlled to travel toward the second floor (nearest floor) in the direction opposite to the traveling direction immediately before the stop. To do. Therefore, in step S407, regardless of the traveling direction immediately before stopping, the presence or absence of traveling (restarting traveling) after stopping at a position where the door 102d cannot be opened or closed is detected, so that the manufacturer or model of the elevator 101 can be notified. The remote monitoring support device 120 can control the intercom call without being influenced by it.
