Description

  The present invention relates to an elevator call management system capable of interphone calls.

  In general, elevator cars include, in an emergency, a user inside the car and an operator outside the car (for example, a maintenance company located in a different location from the building where the elevator is installed). An intercom is provided so that calls can be made. This interphone is connected to a maintenance company as needed by a user in the car, for example, when an emergency call button is operated, and realizes a call between the user and an operator of the maintenance company.

  As a related technology, conventionally, for example, when an emergency call button provided in an elevator car is operated, an interphone and a maintenance service are provided so that a user in the car and a maintenance company operator can talk with each other. There has been a technology for connecting to a management company via a telephone line and recording the sound of an interphone (for example, see Patent Document 1 below).

  Conventionally, the control board of the elevator and the management server computer of the maintenance management company are configured to be able to communicate with each other, and when the car stops, the control board is transferred to the management server computer without user's operation. There was a technology to notify the state of the. As a related technique, for example, in the past, for example, when an abnormality occurs in an elevator, a technique for automatically transmitting images and sounds in a car to a monitoring center side so that bidirectional transmission can be performed (for example, See Patent Document 2).

  The communication between the elevator user and the operator of the maintenance company or the communication between the control board of the elevator and the management server computer of the maintenance company is not always performed, and if the car stops, the elevator may fail. Limited to certain situations, such as For this reason, conventionally, there has been a technique in which the communication board for communication and the communication board for communication are also used to reduce the burden on maintenance workers and the cost of equipment.

JP 2000-26036 A JP-A-7-257842

  However, in the above-described conventional technology, if the communication board for communication and the communication board for communication are used together, the communication and the communication cannot be performed in parallel. For example, in a situation where the telephone line of the maintenance company is saturated, such as when all the telephones of the maintenance company are busy, if an operator calls until the call is started, During that time, not only communication but also communication cannot be performed, and the state of the elevator cannot be notified. For this reason, the above-mentioned conventional technology has a problem that the response is delayed and the user's anxiety is increased.

(System configuration of remote monitoring system)
First, a system configuration of an elevator remote monitoring system for realizing the elevator call management system according to the embodiment of the present invention will be described. FIG. 1 is an explanatory diagram illustrating a system configuration of a remote monitoring system according to an embodiment of the present invention.

  In FIG. 1, a remote monitoring system 100 according to an embodiment of the present invention includes, for example, a control board (control device) 110, a remote monitoring support device 120, a management server computer 130, and a telephone 140. Can be. The remote monitoring system 100 monitors the operation of the elevator 101 using a management server computer 130 installed at a location remote from the elevator 101. 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 place different from the place where the elevator 101 to be monitored is installed and remote from the place where the elevator 101 is installed. Specifically, the management server computer 130 can be installed in, for example, a maintenance management company 150 responsible for maintenance of the elevator 101.

  Telephone 140 is installed, for example, at maintenance management company 150 where 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 car 102 of the elevator 101 and an operator of the maintenance management company 150 can directly communicate with each other.

  The telephone 140 includes a DTMF (Dual Tone Multiplexed Frequency) dialer. The DTMF dialer is acoustically connected to a speaker (a voice circuit transmitter, a microphone) that emits a DTMF signal sound, and sends out the generated DTMF signal sound to a network such as a public voice network via the speaker. Since the configuration of the telephone 140 such as a DTMF dialer is a known technique, the description thereof is omitted.

  The elevator 101 is installed in a multi-storey building or the like, and includes a basket (car) 102 on which people and articles are mounted. One car 102 is provided for each elevator 101. The basket 102 is provided in a hoistway (not shown) penetrating each floor of 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 according to the embodiment of the present invention is not limited to a rope-type elevator. In the remote monitoring system 100 according to the embodiment of the present invention, for example, a hydraulic elevator 101 may be monitored instead of the rope elevator 101 or in addition to the rope elevator 101.

  The basket 102 is provided with an operation panel 102a including an operation button including a destination floor button, a door opening / closing button, and the like, and a display for displaying a floor on which the basket 102 is located. The operation panel 102a provided on the car 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.

  The car 102 is provided with an intercom terminal device 102b. The intercom terminal device 102b includes an emergency call button 102c, a microphone, and a speaker (both are not shown). The intercom terminal device 102b is connected to the remote monitoring support device 120.

  The operation buttons include an emergency call button 102c operated during a call with a manager or an operator outside the car 102. When the emergency call button 102c is operated, the control board for the operation panel 102a transmits a signal (call signal) indicating that the emergency call button 102c is operated to the outside of the intercom terminal device 102b (this embodiment). Is output to the remote 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. Thereby, the remote monitoring system 100 can call the predetermined call destination when the call request of the interphone provided in the car 102 of the elevator 101 is performed.

  The hoistway is provided with a drive mechanism 104 for raising and lowering the car 102. The drive mechanism 104 can be provided, for example, at the upper part of the hoistway. The drive mechanism 104 includes 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 are not shown).

  The driving mechanism 104 can be easily realized by using a known technique, and thus the description is omitted. The drive mechanism 104 is not limited to 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) of the hoistway.

  The basket 102 is connected to one end of a rope 104a, and the counterweight 104b is connected to the other end of the rope 104a. In the rope-type elevator 101, the hoist is driven in a state where a rope 104a having a basket 102 and a counterweight 104b connected to both ends thereof is hung on a pulley and a hoist, and the rope 104a is moved between the rope 104a and the pulley. The basket 102 is moved up and down by using the frictional force (traction). The hoistway is provided with a guide rail (not shown) for guiding the position at which the car 102 moves up and down.

  Doors 105a and 102d are provided at a position (a landing) 105 and a car 102 corresponding to each floor in the hoistway, respectively. The car 102 is provided with a motor (not shown) for opening and closing the door 102d provided on the car 102 and the door 105a provided on the landing 105. The motor that opens and closes the doors 105a and 102d is connected to the control board 110.

  The control board 110 outputs a traveling start signal when the car 102 starts traveling, for example. The control board 110 outputs a traveling stop signal when the traveling car 102 stops traveling, for example. The traveling start signal can be realized, for example, by a dedicated signal notifying that the car 102 has started traveling. Alternatively, the traveling start signal and the traveling stop signal may be realized by, for example, a driving 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 in a state where the elevator 101 arrives at the stop floor, the driving mechanism of the door 102d provided on the car 102 engages with the interlock to release the locking by the interlock, and the door 102d provided on the car 102 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 car 102 is not stopped at the stop position on each floor.

  The elevator 101 is provided with a door opening / closing sensor (not shown) for detecting 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 an open state or a closed state. The door opening / closing sensor can be realized by, for example, a microswitch or a photoelectric sensor. The door opening / closing sensor is connected to the control board 110 via wiring, and a signal output from the door opening / closing sensor is input to the control board 110 via the wiring.

  At each landing 105, an operation panel 105b provided with a landing call button (not shown), a display for displaying a floor on which the car 102 is located, and the like are respectively installed. Each operation panel 105b provided at each landing 105 includes 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 or a wall of a hoistway. The remote monitoring support device 120 includes a main control board 121 and a communication board 122. The main control board 121 is connected to the control board 110. The main control board 121 is connected to the communication board 122. The communication board 122 can be specifically realized by, for example, a PHS (Personal Handy-phone System) board.

  The communication board 122 is connected to the interphone terminal device 102b and the public voice network. Public voice networks include fixed telephone networks (public switched telephone networks) and cellular telephone networks. The public voice network is composed of a plurality of switches (not shown) such as a subscriber line exchange accommodating a telephone line, a relay exchange bundling the subscriber line exchanges, and a gateway exchange connecting to a telephone network of another operator. . Description of the public voice network is omitted because it is a known technique.

  The communication board 122 realized by a PHS board or the like can be used not only for voice communication but also for data communication. In this embodiment, the main control board 121 of the remote monitoring support apparatus 120 is connected to the management server computer 130 via a network 160 such as the Internet connected by the communication board 122. By connecting the main control board 121 and the management server computer 130 via a network 160 such as the Internet in addition to (or instead of) a network 160 such as a public voice network such as a telephone line, a telephone line is punctured in an emergency. By doing so, it is possible to prevent delay in grasping the status of the elevator 101, and to take a quick response.

  Since the installation location of the elevator 101 is fixed, in the remote monitoring system 100, communication quality can be ensured even when communication using PHS is performed, and communication and communication with stable quality can be performed. . In the remote monitoring system 100, by performing communication using the PHS, it is possible to secure communication quality and to reduce communication costs.

  The management server computer 130 can be realized by, for example, a computer device including a CPU, a storage medium such as a ROM, a RAM, or an HD, and an interface with an external device (all are not shown). Specifically, the management server computer 130 can be realized by a computer device such as a personal computer, for example. The management server computer 130 may include an input device such as a keyboard and a mouse, and a display.

  The storage medium of the management server computer 130 includes, for example, a database (not shown) that stores identification information of the elevator 101 and property information of the elevator 101 identified by the identification information in association with each other. The property information can be realized, for example, by information such as the installation location, name, or management number of the elevator 101.

  The installation location of the elevator 101 is indicated as, for example, "XX prefecture XX city @ building" or "XX prefecture XX city @ chome xx address". The name of the elevator 101 can be arbitrarily set by the maintenance management company 150 side, for example, "XX prefecture XX city @ building No. 1 elevator", "shopping center XX △△ store", and the like. Similarly, the management number can be arbitrarily set by the maintenance management company 150 side. The interface with the external device includes an interface for performing information communication with an external device such as the remote monitoring support device 120 and a board for voice communication for performing voice communication with the terminal device 102b of the interphone.

  An operation terminal device 131 may be connected to the management server computer 130. The management server computer 130 and the operation terminal device 131 may be installed at the same place or may be installed at different places. The number of operation terminal devices 131 may be one or more. Specifically, the operation terminal device 131 can be realized by, for example, a computer device such as a personal computer including an input device 131a such as a keyboard and a mouse, and a display 131b. In addition, a printer (not shown) for outputting a report or the like describing the state of the elevator 101 may be connected to the management server computer 130 or the operation terminal device 131.

  In the maintenance management company 150, in addition to the management server computer 130 and the telephone 140, a PBX (Private Branch Exchange, see 205 in FIG. 2) can be installed. Description of the PBX is omitted because it can be easily realized by a known technique. The telephone 140 is connected to a public voice network via a PBX. In the remote monitoring system 100, the telephone 140 may be directly connected to the public voice network without providing the PBX.

(Hardware configuration of remote monitoring system 100)
Next, a hardware configuration of each unit configuring the remote monitoring system 100 according to the embodiment of the present invention will be described. FIG. 2 is an explanatory diagram illustrating a hardware configuration of each unit included in the remote monitoring system 100 according to the embodiment of the present invention.

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

  The control board for the operation panel 102a generates a call signal according to the input operation each time an input operation on an operation button by a user of the elevator 101 or the like is performed, and outputs the generated call signal to the control board 110. I 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 based on, for example, a call signal output from the control board for the operation panel 102a.

  Specifically, the control board 110 generates a control signal for the hoist based on, for example, a call signal output from the control board for the operation panel 102a, and hoists the generated control signal. Output to the machine. Thus, the hoist is rotationally driven in a direction to raise or lower the basket 102. The hoist is controlled by, 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 car 102 is stopped.

  Each time the control board 110 outputs a control signal to the hoist, the control board 110 acquires the number of rotations of the hoist and each motor operated according to the control signal. The number of revolutions of the hoist and each motor can be obtained using, for example, an encoder. Thus, the control board 110 can determine whether or not the hoist has normally operated according to the control signal output to the hoist.

  Further, specifically, the control board 110 is, for example, a control board for operating a brake to stop the car 102 on a predetermined floor based on a call signal output from a control board for the operation panel 102a. A signal is generated, and the generated control signal is output to the brake. The brake operates to stop the raising / lowering operation of the car 102 and stop the car 102 on a predetermined floor according to a control signal output from the control board 110. Thereby, the basket 102 can be stopped on the predetermined floor.

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

  Further, specifically, the control board 110 controls the doors 102 d and 105 a to open and close on the floor where the car 102 is stopped by the brake, based on a call signal output from the control board for the operation panel 102 a, for example. , And outputs the generated control signal to a motor that opens and closes the door 102d of the car 102 and the door 105a of the landing 105. Thus, the doors 102d and 105a can be opened and closed on the floor where the car 102 stops. As described above, the motor that opens and closes the door 105a is locked by a device called an interlock, and therefore does not operate when the door 105a is not completely closed.

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

  The control board 110 outputs a control signal including a floor signal indicating the floor where the car 102 is located, for example, to the control board for the operation panel 102a. The floor on which the car 102 is located can be specified, for example, based on an output signal from a sensor (not shown) provided for each floor in the hoistway. When receiving the control signal including the floor signal, the control board for the operation panel 102a controls the display based on the received control signal to control the floor on which the car 102 is located and the moving direction (during the upward movement). Or descending).

  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 every time the position of the car 102 is switched. 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 car 102, for example. May be used.

  The control board for the operation panel 105b, like the control board for the operation panel 102a, generates a call signal corresponding to the input operation each time an input operation to the hall call button by the 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 is output from the control board for the operation panel 105b, the control board 110 is output from the control board for the operation panel 105b in the same manner as when the signal is output from the control board for the operation panel 102a. Based on the signals, various control signals are generated, and the generated control signals are output to the corresponding units to control the operation of the elevator 101.

  The control board 110 outputs a start signal indicating that each part is started to move the car 102 up and down every time the car 102 is moved up and down according to the signal output from the operation panel 102a and the operation panel 105b. . For example, when the control board 110 moves from the first floor to the second floor, the control board 110 outputs an activation signal once. Further, for example, when the control board 110 moves from the first floor to the fifth floor without stopping halfway, it outputs a start signal once. In addition, for example, when the control board 110 stops on the third floor on the way from the first floor (opens and closes the door) and then moves to the fifth floor, it outputs a start signal twice.

  The control board 110 may calculate the traveling distance and traveling time of the car 102 each time the car 102 is moved up and down. The travel distance of the car 102 can be calculated based on, for example, the number of times of activation. The travel time of the car 102 can be calculated based on, for example, the floor signal described above. More specifically, for example, when a call operation is received from the operation panel 105b of the fourth floor landing 105 while the car 102 is on the first floor, the car 102 moves on the third floor from the first floor to the fourth floor. I do.

  The control board 110 includes a memory (not shown), and stores the number of times the start signal is output, that is, the number of starts, in the memory every time the start signal is output. The control board 110 may store, in the memory, the history of the operation operation of each part driven when the car 102 is moved up and down and the doors 105a and 102d are opened and closed, instead of or in addition to the number of starts. Specifically, the control board 110 relates to, for example, the number of times of activation, the traveling distance of the car 102, the traveling time of the car 102, the number of times of operation of various relays operated when the car 102 is raised and lowered, and the doors 105a and 102d are opened and closed. The information may be stored in the memory as a history of the operation.

  In addition, 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 a control signal for opening and closing the doors 102d and 105a output by the control board 110 and an output value of the door open / close sensor. It can be determined whether the doors 102d and 105a have actually opened and closed.

  Further, when the operation mode of the elevator 101 changes, the control board 110 outputs a signal (signal for issuing a signal) indicating that the operation mode has been switched. Specifically, 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 control board 110 informs the outside that the operation mode has been switched. A signal (signal for notification) or a signal (signal for notification) for notifying the operation mode after switching (the operation mode other than the normal operation mode) is output (signaled). .

  Further, specifically, for example, when the operation mode of the elevator 101 switches from an operation mode other than the normal operation mode to the normal operation mode, the control board 110 determines that the operation mode has been switched. A signal (reporting signal) notifying the outside or a signal (reporting signal) notifying the operation mode after switching (that is, the normal operation mode) is output (reported).

  Further, when detecting a failure in the elevator 101, the control board 110 outputs (reports) a signal (signal for notification) notifying the occurrence of the failure. Specifically, for example, the control board 110 outputs the control signal for opening and closing the doors 105a and 102d, but the corresponding doors 105a and 102d do not operate based on the output value of the door open / close sensor. When it is detected, a signal (reporting signal) notifying that a failure has occurred in the corresponding doors 105a and 102d of the elevator 101 is output.

  The control board 110 can output (report) a signal for alerting to the outside of the control board 110 via, for example, a wiring connecting the control board 110 and an external device. More specifically, the control board 110 is configured such that, for example, a wiring connecting the control board 110 and an external device outputs a signal for alerting via a contact connected to the control board 110 to the outside of the control board 110. (Report).

  The control board 110 may output a signal for alerting to the outside of the control board 110 via a terminal provided on the control board 110, for example. Specifically, the control board 110 can output a signal for alerting to the outside of the control board 110, for example, via a communication terminal for performing communication with an external device of the elevator 101. . Alternatively, specifically, the control board 110 is provided, for example, via a terminal (hereinafter, referred to as a “maintenance inspection terminal”) provided on the control board 110 and capable of connecting a diagnostic terminal device to the control board 110. Thus, the alarm signal may be output to the outside of the control board 110.

  When the emergency call button 102c is operated, the intercom terminal device 102b outputs a call signal indicating that the operation has been performed to the remote monitoring support device 120. The call signal is input to the relay board 201 included in the main control board 121. The call signal may be directly input to the monitoring control board 202 in addition to or instead of the relay board 201.

  The call signal is input directly to the communication board 122 in addition to the relay board 201 or in place of the relay board 201, so that the monitor control board 202 included in the main control board 121 does not operate for some reason. Also, voice communication (call) can be performed between the terminal device 102b of the interphone and the telephone 140.
