Description

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

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

  As a related technology, for example, when an emergency call button provided in an elevator car is operated, the interphone and maintenance are made so that conversation between the user in the car and the operator of the maintenance management company becomes possible. There has been a technique of connecting a management company via a telephone line and recording voice of an interphone (see, for example, 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 communicable, and when the car stops, the control board is connected to the management server computer without any user operation. There was a technology to notify the status of. As a related technique, conventionally, for example, when an abnormality occurs in an elevator, the image and sound in the basket are automatically transmitted to the monitoring center side, and bidirectional transmission can be performed (for example, the following) (See Patent Document 2).

  Communication between the elevator user and the operator of the maintenance management company and communication between the elevator control board and the management server computer of the maintenance management company are not always performed. If the car stops, the elevator will fail. Limited to certain situations. For this reason, conventionally, there has been a technique in which a communication board for communication and a communication board for communication are combined to reduce the burden on the worker for maintenance and the cost of equipment.

JP 2000-26036 A Japanese Patent Laid-Open No. 7-257842

  However, in the above-described conventional technology, if the communication board for communication and the communication board for communication are combined, the call and communication cannot be performed in parallel. For example, when the operator's call is made until the call is started in a situation where the telephone line of the maintenance management company side is saturated, such as when all the telephones of the maintenance management company side are busy, During that time, not only a call but also a communication cannot be performed, and the state of the elevator cannot be notified. For this reason, the above-described conventional technology has a problem in 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 that realizes an elevator call management system according to an embodiment of the present invention will be described. FIG. 1 is an explanatory diagram showing 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 do. The remote monitoring system 100 monitors the operation of the elevator 101 using a management server computer 130 installed at a remote location of 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 away from the place where the elevator 101 is installed, which is different from the place where the elevator 101 to be monitored is installed. Specifically, the management server computer 130 can be installed, for example, in a maintenance management company 150 that performs 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 car 102 of the elevator 101 and an operator of the maintenance management company 150 can talk directly.

  The telephone 140 includes a DTMF (Dual Tone Multiplexed Frequency) dialer. The DTMF dialer is acoustically connected to a speaker (voice circuit transmitter, microphone) that emits a DTMF signal sound, and transmits the generated DTMF signal sound to a network such as a public voice network through the speaker. Since the configuration of the telephone 140 such as a DTMF dialer is a known technique, a description thereof will be 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 basket 102 is provided for each elevator 101. The basket 102 is provided in a hoistway (not shown) penetrating 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 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 operation buttons including a destination floor button and a door opening / closing button, a display for displaying the floor where the basket 102 is located, and the like. An 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.

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

  The operation buttons include an emergency call button 102 c that is operated during a call with an administrator or operator outside the car 102. When the emergency call button 102c is operated, the control board for the operation panel 102a sends a signal (call signal) indicating that the emergency call button 102c has been operated to the outside of the interphone terminal device 102b (this embodiment). Is output to the remote monitoring support device 120).

  In this embodiment, the call request operation 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 an interphone call request operation provided on the car 102 of the elevator 101 is operated.

  The hoistway is provided with a drive mechanism 104 that is involved in the raising / lowering operation of the car 102. The drive mechanism 104 can be provided in the upper part in a hoistway, for example. The drive mechanism 104 includes a hoisting machine, 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).

  Since the drive mechanism 104 can be easily realized by using a known technique, the description thereof is omitted. The drive mechanism 104 is not restricted to what is provided in the upper part in a 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 having the cage 102 and the counterweight 104b connected to both ends is hooked on the pulley and the hoisting machine, and between the rope 104a and the pulley. The cage 102 is moved up and down using the frictional force (traction). The hoistway is provided with a guide rail (not shown) for guiding the raising / lowering position of the basket 102.

  Doors 105a and 102d are provided at positions (depots) 105 and the cage 102 corresponding to the floors in the hoistway, respectively. The car 102 is provided with a motor (not shown) that opens and closes the door 102d provided on the car 102 and the door 105a provided on the landing 105. A motor that opens and closes the doors 105 a and 102 d is connected to the control board 110.

  For example, when the car 102 starts traveling, the control board 110 outputs a traveling start signal. For example, when the traveling car 102 stops traveling, the control board 110 outputs a traveling stop signal. The travel start signal can be realized by, for example, a dedicated signal for notifying that the car 102 has started traveling. Or you may implement | achieve a driving | running | working start signal and a driving | running | working stop signal with the drive signal output with respect to a winding machine, for example.

  A 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 has arrived at the stop floor, the drive mechanism portion of the door 102d provided in the cage 102 and the interlock are engaged, and the locking by the interlock is released, and the door 102d provided in the cage 102 is released. And the door 105a provided in the landing 105 opens and closes in conjunction. As a result, the door 105a provided at the landing 105 is in a closed state when the basket 102 is not stopped at the stop position on each floor.

  The elevator 101 includes a door opening / closing sensor (not shown) that detects opening and 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 open or closed. The door opening / closing sensor can be realized by, for example, a micro switch 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.

  Each platform 105 is provided with an operation panel 105b including a platform call button (not shown), a display for displaying a floor where the basket 102 is located, and the like. Each operation panel 105b provided in each platform 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 that houses 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 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. Specifically, the communication substrate 122 can be realized by a PHS (Personal Handy-phone System) substrate, for example.

  The communication board 122 is connected to the interphone terminal device 102b and the public voice network. The public voice network includes a fixed telephone network (public switched telephone network) and a mobile telephone network. The public voice network is composed of a plurality of exchanges (not shown) such as subscriber line exchanges that accommodate telephone lines, relay exchanges that bundle the subscriber line exchanges, and gateway exchanges that connect to the telephone networks of other operators. . Description of the public voice network is omitted because it is a known technology.

  The communication substrate 122 realized by a PHS substrate or the like can be used for voice communication and also for data communication. In this embodiment, the main control board 121 in the remote monitoring support device 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) the network 160 such as a public voice network such as a telephone line, the telephone line is punctured in an emergency. By doing so, it is possible to prevent delay in grasping the situation of the elevator 101 and to take a quick response.

  Since the installation location of the elevator 101 is fixed, the remote monitoring system 100 can ensure the quality of communication even when performing communication using PHS, and can perform calls and communication with stable quality. . And in the remote monitoring system 100, by performing communication using PHS, the quality of communication can be ensured and the cost for communication can be suppressed.

  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, an interface with an external device (all not shown), and the like. 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, a display, and the like.

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

  The installation location of the elevator 101 is indicated, for example, as “XX prefecture ×× city ΔΔ building”, “XX prefecture ×× city Δchome ○ address”. The name of the elevator 101 can be arbitrarily set by the maintenance management company 150 such as “XX prefecture XX city ΔΔ building No. 1 elevator”, “shopping center XX ΔΔ store”, and the like. Similarly, the maintenance management company 150 can arbitrarily set the management number. 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 voice communication substrate for performing voice communication with the interphone terminal device 102b.

  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 in the same place or in different places. One or more terminal devices 131 may be used for operation. Specifically, the operation terminal device 131 can be realized by a computer device such as a personal computer including an input device 131a such as a keyboard and a mouse, a display 131b, and the like. Further, a printer (not shown) for outputting a report describing the state of the elevator 101 may be connected to the management server computer 130 and 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 reference numeral 205 in FIG. 2) can be installed. The description of PBX is omitted because it can be easily realized by a known technique. The telephone 140 is connected to the public voice network via the PBX. In remote monitoring system 100, telephone 140 may be directly connected to the public voice network without providing PBX.

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

  In FIG. 2, the control board 110 controls the 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 of the elevator 101 based on the signal output from each part.

  The control board for the operation panel 102a described above generates a call signal corresponding to the input operation every time an input operation to the operation button by a user of the elevator 101 or the like is received, and outputs the generated call signal to the control board 110. To do. The control board 110 controls the operation 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, for example, the control board 110 generates a control signal for the hoisting machine based on a call signal output from the control board for the operation panel 102a, and winds up the generated control signal. Output to the machine. As a result, the hoisting machine is driven to rotate in a direction in which the car 102 is raised or lowered. The hoisting machine is controlled using, for example, an inverter, and is driven and controlled by the control board 110 so as to stop the rotation at the floor where the car 102 is stopped.

  Each time the control board 110 outputs a control signal to the hoisting machine, the control board 110 acquires the number of rotations of the hoisting machine and each motor operated according to the control signal. The number of rotations of the hoisting machine and each motor can be obtained using, for example, an encoder. Thereby, the control board 110 can determine whether the said winding machine operate | moved normally according to the signal for control output with respect to the winding machine.

  Specifically, for example, the control board 110 is used for control to operate a brake so as to stop the car 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 in accordance with a control signal output from the control board 110 to stop the raising / lowering operation of the car 102 and to stop the car 102 on a predetermined floor. Thereby, 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 micro switch or a photoelectric sensor. Thereby, the control board 110 can determine whether or not the brake has operated normally according to the control signal output to the brake.

  Specifically, for example, the control board 110 controls to open and close the doors 102d and 105a on the floor where the basket 102 is stopped by a brake based on a call signal output from the control board for the operation panel 102a. And the generated control signal is output to a motor that opens and closes the door 102d of the car 102 and the door 105a of the landing 105. Accordingly, the doors 102d and 105a can be opened and closed on the floor where the basket 102 is stopped. As described above, since the motor that opens and closes the door 105a is locked by a device called an interlock or the like, the motor 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 each time a control signal is output to the motor that opens and closes the doors 102d and 105a. As a result, the control board 110 can determine whether or not the doors 102d and 105a are operating normally in accordance with a control signal output to the motor that opens and closes the corresponding doors 102d and 105a.

  For example, the control board 110 outputs a control signal including a floor signal indicating the floor on which the car 102 is located to the control board for the operation panel 102a. The floor on which the car 102 is located can be specified based on, for example, 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 unit based on the received control signal, and the floor where the cage 102 is located and the moving direction (ascending) Or is it going down).

  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, whenever 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 cage 102, for example. You may do.

  Like 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 every time an input operation to the landing call button by a user of the elevator 101 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 an activation signal indicating that each unit has been activated in order to move the car 102 up and down every time the car 102 is moved up and down in response to a signal output from the operation panel 102 a or the operation panel 105 b. . For example, when the control board 110 moves from the first floor to the second floor, it outputs the activation signal once. For example, when the control board 110 moves from the first floor to the fifth floor without stopping on the way, the control board 110 outputs the activation signal once. Further, for example, when the control board 110 moves from the first floor to the fifth floor after stopping on the third floor in the middle (opening / closing the door), the control board 110 outputs the activation signal twice.

  The control board 110 may calculate the travel distance and travel time of the car 102 each time the car 102 is moved up and down. The travel distance of the basket 102 can be calculated based on, for example, the number of activations. Further, the traveling time of the car 102 can be calculated based on the floor signal, for example. Specifically, for example, when a call operation is received from the operation panel 105b of the fourth-floor platform 105 with the basket 102 on the first floor, the basket 102 moves from the first floor to the fourth floor for the third floor. To do.

  The control board 110 includes a memory (not shown), and stores the number of times the activation signal is output, that is, the number of activations, in the memory every time the activation signal is output. The control board 110 may store, in the memory, the history of operation of each unit driven during the raising / lowering operation of the car 102 or the opening / closing operation of the doors 105a and 102d, instead of or in addition to the number of activations. Specifically, the control board 110 relates to, for example, the number of activations, the travel distance of the car 102, the travel time of the car 102, the number of operations of various relays that are operated when the car 102 is raised and lowered, and the doors 105a and 102d are opened and closed. Information may be stored in the memory as a history of operation.

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

  In addition, when the operation mode of the elevator 101 changes, the control board 110 outputs a signal (report 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. Output (report) a signal to notify (signal to issue) or a signal to notify the operation mode after switching (that is, an operation mode other than the normal operation mode) .

  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 the normal operation mode, the operation mode is switched. A signal (signal for notification) to be notified to the outside, or a signal (signal for notification) to be notified of the operation mode after switching (the normal operation mode) is output (report issuance).

  In addition, when a failure is detected in the elevator 101, the control board 110 outputs (reports) a signal (notification signal) notifying the occurrence of the failure. Specifically, for example, the control board 110 outputs a 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 opening / closing sensor. When this is detected, a signal (notification signal) notifying that a failure has occurred in the corresponding doors 105a and 102d in the elevator 101 is output.

  For example, the control board 110 can output (report) an alarm signal to the outside of the control board 110 via 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 for connecting the control board 110 and an external device sends an alarm signal to the outside of the control board 110 via a contact point connected to the control board 110. Can be output (reported).

  For example, the control board 110 may output an alarm signal to the outside of the control board 110 via a terminal provided on the control board 110. Specifically, the control board 110 can output a signal for reporting to the outside of the control board 110 via a communication terminal that communicates with an external device of the elevator 101, for example. . 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, a signal for reporting may be output to the outside of the control board 110.

  When the emergency call button 102c is operated, the interphone 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 the relay board 201 or instead of the relay board 201.

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