Description

[Technical field]

[0001] The present invention relates to an elevator intercom, an elevator, and an elevator system. [Background technology]

[0002] Generally, an intercom is installed in an elevator car to communicate with the outside world. This intercom is configured with a mechanical switch, a so-called push button. When the intercom is configured with a mechanical switch, an inspector must go to the site and actually press the intercom to inspect the intercom. In recent years, there has been a demand for inspecting intercoms remotely.

[0003] For example, Patent Document 1 describes a technology that allows remote inspection of an intercom. Patent Document 1 describes a technology for a push button that includes a push button operation unit operated by a finger or the like, a light-emitting unit arranged to irradiate light toward the push button operation unit, and a light-receiving unit arranged to receive the light from the light-emitting unit. In a normal state, the light-receiving unit of the push button detects the light from the light-emitting unit, and when the push button operation unit is operated, the light from the light-emitting unit is blocked and the light-receiving unit operates to register that the push button has been operated and to light the light-emitting unit as a response lamp. In addition, during automatic inspection of the push button, the light-emitting unit is electrically turned off to check the operating status of the signal circuit following the light-receiving unit, and further, the light-emitting unit is electrically turned on to check whether the response lamp is on.

[0004] [Patent Document 1] JP 2007-022725 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, the technology described in Patent Document 1 only had one type of sensor, a photoelectric sensor, to determine whether the intercom was operated. Therefore, the technology described in Patent Document 1 had the problem that if a user's finger unintentionally approached the light receiving section, the light could be blocked and the intercom could be operated, leading to erroneous operation of the intercom and the generation of a false alarm.

[0006] In consideration of the above problems, an object of the present invention is to provide an elevator intercom, elevator, and elevator system that can suppress operational errors by users. [Means for solving the problem]

[0007] In order to solve the above problems and achieve this object, the elevator intercom is an intercom installed in an in-car operation panel of an elevator car. The intercom includes a photoelectric sensor, an illuminance sensor, and a control unit. The photoelectric sensor is installed in the in-car operation panel, and consists of a light-projecting unit that projects light and a light-receiving unit that receives light from the light-projecting unit, and is turned ON when the light from the light-projecting unit is blocked. The illuminance sensor is installed in the in-car operation panel, and is turned ON when the amount of light detected drops to a threshold value. The control unit determines that an operation has been performed when both the photoelectric sensor and the illuminance sensor are turned ON.

[0008] The elevator includes a car that moves up and down in a hoistway, an in-car operation panel provided in the car room, and an interphone provided on the in-car operation panel. The interphone is the above-mentioned interphone.

[0009] The elevator system also includes a car that moves up and down in a hoistway, an in-car operation panel provided in the car room of the car, an intercom provided on the in-car operation panel, an elevator control device that controls the car, and a communication device provided on the elevator control device. The elevator system also includes an external terminal having a communication device capable of transmitting and receiving information from the communication device of the elevator control device. The intercom is the above-mentioned intercom. Effect of the Invention

[0010] According to the elevator intercom, elevator, and elevator system configured as described above, operational errors by users can be suppressed. [Brief description of the drawings]

[0012] Hereinafter, an elevator intercom structure, an elevator, and an elevator system according to an embodiment will be described with reference to Fig. 1 to Fig. 6. In addition, the same reference numerals are used to designate common members in each drawing.

[0013] 1. Example of embodiment 1-1. Elevator car configuration First, an example of the configuration of an elevator car to which the present invention is applied will be described with reference to Fig. 1. Fig. 1 is a schematic configuration diagram showing an elevator car.

[0014] As shown in Fig. 1, the car 10 has a car chamber 11 and a car door 12. The car chamber 11 is formed in a hollow, substantially rectangular parallelepiped shape. The car 10 also has a load sensor 17 and a monitoring camera 18 (see Fig. 4). An in-car control unit 41 (see Fig. 4) of the car 10 determines the presence or absence of a passenger in the car chamber 11 by the load sensor 17 and the monitoring camera 18.

[0015] The car chamber 11 has a ceiling 13, a front panel 14, a plurality of side panels 15, and a floor panel 16. An opening is formed in the front panel 14. A car door 12 is installed in the opening of the front panel 14 so as to be able to open and close. In addition, an in-car operation panel 21 is provided on the front panel 14.

[0016] A ceiling 13 is provided at the top of the car chamber 11 in the vertical direction, and a floor board 16 is provided facing the ceiling 13 in the vertical direction. An interior car light 22 is provided on the ceiling 13.

[0017] The in-car operation panel 21 has a display unit 23, a plurality of input units 24 for inputting the destination floor, an opening / closing button 25 for inputting the opening / closing operation of the car door provided on the elevator car 10, and an intercom 26 for passengers to contact the outside world.

[0018] 1-2.Intercom configuration Next, the detailed configuration of the interphone 26 will be described with reference to FIGS. FIG. 2 is a perspective view showing the interphone 26, and FIG. 3 is a side view of the interphone 26. As shown in FIG.

[0019] As shown in Fig. 2 and Fig. 3, the intercom 26 has an illuminance sensor 31 that detects brightness, and a photoelectric sensor 32. The intercom 26 also has a first member 34, a second member 35, and a front portion 36. The first member 34 and the second member 35 face each other in the vertical direction. The first member 34 is disposed at the upper portion in the vertical direction, and the second member 35 is disposed at the lower portion in the vertical direction. The first member 34 and the second member 35 protrude from the in-car operation panel 21 and the front panel 14 toward the inside of the car chamber 11. The distance between the first member 34 and the second member 35 is set to a distance that allows a user to insert his / her finger.

[0020] Although an example in which the first member 34 and the second member 35 are opposed to each other in the vertical direction has been described, this is not limited to this, and the first member 34 and the second member 35 may be opposed to each other in a horizontal direction perpendicular to the vertical direction.

[0021] The first member 34 is provided with a light-projecting unit 32a of the photoelectric sensor 32. The light-projecting unit 32a irradiates light L1 from the first member 34 toward the second member 35. The second member 35 is provided with a light-receiving unit 32b of the photoelectric sensor 32. The light-receiving unit 32b receives the light L1 irradiated from the light-projecting unit 32a. When the light L1 irradiated to the light-receiving unit 32b is blocked, the photoelectric sensor 32 turns ON and detects the user's finger.

[0022] The front portion 36 is disposed between the first member 34 and the second member 35. The front portion 36 is disposed on the base end side in the protruding direction of the first member 34 and the second member 35, i.e., on the side of the in-car operation panel 21 and the front plate 14. In other words, the front portion 36 is disposed at a position recessed from the path of the light L1 irradiated from the light-projecting portion 32a of the photoelectric sensor 32 toward the in-car operation panel 21 and the front plate 14.

[0023] A sensor hole 36a is formed on the front surface of the front section 36 facing the inside of the car chamber 11. An illuminance sensor 31 is provided inside the front section 36. The illuminance sensor 31 is disposed at a position facing the sensor hole 36a provided in the front section 36. The illuminance sensor 31 detects external light through the sensor hole 36a. When a user's finger approaches the sensor hole 36a and the amount of light detected by the illuminance sensor 31 falls to a threshold value, the illuminance sensor 31 turns ON and detects the user's finger.

[0024] In addition, by providing the illuminance sensor 31 inside the front portion 36 and forming a sensor hole 36a in the front portion 36 facing the illuminance sensor 31, it is possible to prevent the detection surface of the illuminance sensor 31 from being blocked against the user's intention.

[0025] 1-3. Elevator system configuration Next, the configuration of an elevator system 200 having the above-mentioned intercom 26 will be described with reference to FIG. FIG. 4 is a block diagram showing a control system of the elevator system 200.

[0026] As shown in FIG. 4, the elevator system 200 includes a car 10, an elevator control device 100, an external manager 120 representing a building owner or manager, and an external terminal 130 representing a monitoring center, a sales office, a program on the cloud, etc.

[0027] The car 10 has an in-car light 22, an illuminance sensor 31, a photoelectric sensor 32, a switching unit / operation confirmation unit 42, an in-car control unit 41, a load sensor 17, and a surveillance camera 18. The load sensor 17, the surveillance camera 18, and the switching unit / operation confirmation unit 42 are connected to the in-car control unit 41. The in-car control unit 41 determines the presence or absence of a user in the car room 11 based on information from the load sensor 17 and the surveillance camera 18.

[0028] The car interior lighting 22, the illuminance sensor 31, and the photoelectric sensor 32 are connected to the car interior control unit 41 via a switching unit / operation confirmation unit 42. The switching unit / operation confirmation unit 42 turns on / off the car interior lighting 22, the illuminance sensor 31, and the photoelectric sensor 32 based on a control signal from the car interior control unit 41. In addition, the switching unit / operation confirmation unit 42 transmits detection signals from the illuminance sensor 31 and the photoelectric sensor 32 to the car interior control unit 41.

[0029] The car inside control unit 41 determines that the intercom 26 has been operated when both the illuminance sensor 31 and the photoelectric sensor 32 are ON, i.e., when both the illuminance sensor 31 and the photoelectric sensor 32 detect the user's finger. This enables the intercom 26 to be used. In this way, according to the intercom 26 of this example, by having two types of sensors, the illuminance sensor 31 and the photoelectric sensor 32, it is possible to prevent erroneous operation. Note that, although an example has been described in which the car inside control unit 41 is used as the control unit, this is not limiting, and the control unit may be provided in the intercom 26.

[0030] 2 and 3, the sensor hole 36a through which the illuminance sensor 31 receives light is disposed in a position in the intercom 26 that is further back than the passage (hereinafter referred to as the optical path) of the light L1 emitted from the light-projecting portion 32a of the photoelectric sensor 32. Therefore, in order for the illuminance sensor 31 to turn ON, the user's finger needs to pass through the optical path of the light L1 of the photoelectric sensor 32. As a result, erroneous operation of the intercom 26 can be more effectively prevented.

[0031] Furthermore, the car control unit 41 is connected to the elevator control device 100 so as to be able to transmit and receive information to and from the elevator control device 100. The elevator control device 100 has an elevator control unit 101, an operation mode switching unit 102, an operation check result storage unit 103, a hall terminal 104, and a communication device 105.

[0032] The operation mode switching unit 102, the operation check result storage unit 103, the hall terminal 104, and the communication device 105 are connected to the elevator control unit 101. The operation mode switching unit 102 switches the operation mode of the elevator between a normal operation mode and a diagnostic operation mode based on a control command from the elevator control unit 101.

[0033] The operation check result storage unit 103 stores the operation check result of the intercom 26 in the diagnostic operation mode. The operation check result storage unit 103 also transmits the operation check result of the intercom 26 to the outside via the communication device 105.

[0034] The hall terminals 104 are arranged at each of the floors where the elevator car 10 stops in the building structure. The hall terminals 104 are provided with an input unit for inputting the destination direction of the car 10 and a display unit for displaying various information.

[0035] The communication device 105 of the elevator control device 100 is connected to an external manager 120 and an external terminal 130 so as to be able to send and receive information.

[0036] The external manager 120 has a communication device 121 and a receiving terminal 122. Various terminal devices such as a mobile terminal and a personal computer are applied as the communication device 121 and the receiving terminal 122. The communication device 121 receives information from the communication device 105 of the elevator control device 100 and transmits it to the receiving terminal 122.

[0037] The external terminal 130 has a communication device 131 and a management server 132. The external terminal 130 also has an office 134 that issues work information commands to an operator 140. Various information is transmitted to the management server 132 from the communication device 105 of the elevator control device 100 via the communication device 131. The management server 132 then stores the various information transmitted from the elevator control device 100. The operator 140 also performs work such as failure response 150 based on the information stored in the management server 132.

[0038] In addition, the elevator control unit 101 and the car control unit 41 each include, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and a non-volatile storage, all of which are connected to a bus.

[0039] The CPU reads out the program code of the software that realizes each function according to the present embodiment from the ROM, expands it in the RAM, and executes it. Note that the control processing unit may include a processing device such as an MPU (Micro-Processing Unit) instead of the CPU. Variables, parameters, etc. that are generated during the calculation process are temporarily written to the RAM.

[0040] Examples of non-volatile storage that can be used include a hard disk drive (HDD), a solid state drive (SSD), a flexible disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a magnetic tape, and a non-volatile memory card. In addition to an operating system (OS) and various parameters, programs for operating the control processing unit are recorded in the non-volatile storage. The programs may be stored in a ROM.

[0041] The program is stored in the form of a computer-readable program code, and the CPU sequentially executes operations according to the program code. In other words, a ROM or non-volatile storage is used as an example of a computer-readable non-transitory recording medium that stores a program to be executed by a computer.

[0042] 2. Example of intercom inspection operation Next, an example of the operation of inspecting the interphone 26 having the above-mentioned configuration will be described with reference to FIGS. 5 and 6 are flow charts showing an example of the inspection work operation of the intercom 26. FIG.

[0043] 5 and 6, first, the elevator control unit 101 confirms that there is no user in the car 10 based on information from the car in-car control unit 41 (step S11). In the process of step S11, based on information from the load sensor 17 and the monitoring camera 18 provided in the car 10, it is confirmed that the car 10 is unoccupied.

[0044] Next, the elevator control unit 101 checks whether the elevator is not being used (step S12). In the process of step S12, the elevator control unit 101 judges whether a call operation for the car 10 is not being performed based on information from the hall terminal 104 installed at each boarding / descending floor. In the process of step S12, if the elevator control unit 101 judges that the elevator is being used (NO judgment in step S12), the process returns to step S11.

[0045] In addition, in the process of step S12, if the elevator control unit 101 determines that the elevator is not being used (YES judgment in step S12), the process proceeds to step S13. In the process of step S13, the elevator control unit 101 uses the operation mode switching unit 102 to switch the operation mode of the elevator to the diagnostic operation mode.

[0046] Next, the elevator control unit 101 notifies the user or an external manager 120 such as a building owner that the elevator is in the diagnostic operation mode via the hall terminal 104 and the communication device 105 (step S14). In the process of step S14, for example, the display unit of the hall terminal 104 displays that the elevator is in the diagnostic operation mode.

[0047] Next, the elevator control unit 101 moves the car 10 to a predetermined diagnosis position (step S15). In the process of step S15, in the case of an elevator in which light enters the car room 11 from outside the car 10, that is, an elevator with glass windows on the car door 12, side panel 15, etc., the elevator control unit 101 moves the car 10 between floors. In other words, the elevator control unit 101 moves the car 10 to a position where light does not enter the car room 11 of the car 10 from outside.

[0048] Also, in the process of step S15, in the case of an elevator in which no light enters the car room 11 from outside the car 10, the elevator control unit 101 stops the car 10 at the current position.

[0049] Next, the car interior control unit 41 uses the switching unit / operation confirmation unit 42 to cut off the power to the car interior lighting 22 and the light-projecting unit 32a of the photoelectric sensor 32 (step S16). In the process of step S16, the car interior lighting 22 is turned off and the light projection unit 32a of the photoelectric sensor 32 stops projecting light. This makes the car chamber 11 a dark room.

[0050] Next, the car inside control unit 41 performs an operation of checking the state of the intercom 26 using the switching unit / operation checking unit 42 (step S17). Then, the car inside control unit 41 judges whether the intercom 26 has been pressed (step S18). Here, in the process of step S16, the car inside lighting 22 and the light projecting unit 32a are turned off, so the light in the car room 11 is reduced. Therefore, when the intercom 26 is operating normally, the light receiving unit 32b of the photoelectric sensor 32 detects light blocking, so the photoelectric sensor 32 is turned ON, and the illuminance sensor 31 detects darkness, so the illuminance sensor 31 is turned ON. Therefore, since both the illuminance sensor 31 and the photoelectric sensor 32 are turned ON, the intercom 26 is in a pressed state (operated state).

[0051] On the other hand, when the illuminance sensor 31 does not detect darkness, or when the light receiving section 32b of the photoelectric sensor 32 does not detect light blocking, the operation of the intercom 26 is turned off. Therefore, it can be determined that an abnormality has occurred in the intercom 26.

[0052] In the process of step S18, if the car internal control unit 41 determines that the intercom 26 is pressed (YES judgment in step S18), it determines that there is no problem with the operation of the intercom 26 (step S19). In addition, in the process of step S18, if the car internal control unit 41 determines that the intercom 26 is not pressed (NO judgment in step S18), it determines that there is a problem with the operation of the intercom 26 (step S20).

[0053] When the processing of step S19 or step S20 is completed, the car interior control unit 41 uses the switching unit / operation confirmation unit 42 to power on the car interior lighting 22 and the light-projecting unit 32a of the photoelectric sensor 32 (step S21). As a result, the car interior lighting 22 is turned on and light is emitted from the light-projecting unit 32a. Then, the light-receiving unit 32b of the photoelectric sensor 32 receives the light, so the photoelectric sensor 32 turns OFF. In addition, the illuminance sensor 31 detects the light, so the illuminance sensor 31 also turns OFF. As a result, the state of the intercom 26 turns OFF, and the states of the illuminance sensor 31 and the photoelectric sensor 32 are reset.

[0054] 6, the car interior control unit 41 uses the switching unit / operation confirmation unit 42 to cut off the power to the car interior lighting 22 and the light projecting unit 32a of the photoelectric sensor 32 (step S22). As a result, the inside of the car chamber 11 becomes a dark room again.

[0055] Next, the car control unit 41 performs an operation to check the state of the intercom 26 using the switching unit / operation check unit 42 (step S23). Then, the car control unit 41 determines whether the intercom 26 has been pressed (step S24).

[0056] In the process of step S24, if the car internal control unit 41 determines that the intercom 26 is pressed (YES judgment in step S24), it determines that there is no problem with the operation of the intercom 26 (step S25). In addition, in the process of step S18, if the car internal control unit 41 determines that the intercom 26 is not pressed (NO judgment in step S24), it determines that there is a problem with the operation of the intercom 26 (step S26).

[0057] Next, the car inside control unit 41 uses the switching unit / operation confirmation unit 42 to determine whether the operation confirmation result of step S18 and the operation confirmation result of step S24 have consecutively become the same result (step S27). If the car inside control unit 41 determines in the process of step S27 that the consecutive results have not become the same result (NO judgment in step S27), the process returns to step S16 shown in Fig. 5 and the operations from step S16 to step S27 are performed again.

[0058] Furthermore, in the process of step S27, if the car in-control section 41 determines that the same result has occurred consecutively (YES judgment in step S27), the process proceeds to step S28. As shown in the processes of steps S16 to S27, by checking the operation of the intercom 26 multiple times (twice in this example), it is possible to eliminate the influence of disturbances and improve the accuracy of the inspection. Note that the operation checking operations shown in steps S16 to S27 are not limited to two times, and may be performed three or more times.

[0059] In the processing of step S28, the car in-control unit 41 transmits the operation check result to the operation check result storage unit 103 of the elevator control device 100. Then, the operation check result storage unit 103 stores the operation check result and transmits it to the external manager 120 or the external terminal 130 via the communication device 105. The external terminal 130 stores the received operation check result in the management server 132. Then, based on the operation check result stored in the management server 132, the operator 140 performs failure response 150 if the operation check is NG.

[0060] Here, the operation check result may include not only information on whether there is a problem with the operation of the intercom 26, but also the states of the illuminance sensor 31 and the photoelectric sensor 32. That is, in the processing of steps S18 and S24, if the illuminance sensor 31 does not detect darkness, the operation check result includes that an abnormality has occurred in the illuminance sensor 31. Also, in the processing of steps S18 and S24, if the light receiving unit 32b of the photoelectric sensor 32 does not detect light blocking, the operation check result includes that an abnormality has occurred in the photoelectric sensor 32. This makes it possible to easily determine, in the event that a problem has occurred with the operation of the intercom 26, whether an abnormality has occurred in either the illuminance sensor 31 or the photoelectric sensor 32, or both.

[0061] When the process of step S28 is completed, the car interior control unit 41 uses the switching unit / operation confirmation unit 42 to power on the car interior lighting 22 and the light-projecting unit 32a of the photoelectric sensor 32 (step S29). As a result, the car interior lighting 22 is turned on and light is emitted from the light-projecting unit 32a. Then, the light-receiving unit 32b of the photoelectric sensor 32 receives the light, so the photoelectric sensor 32 turns OFF. Furthermore, the illuminance sensor 31 detects the light, so the illuminance sensor 31 also turns OFF. As a result, the state of the intercom 26 turns OFF.

[0062] Next, the elevator control unit 101 switches the operation mode of the elevator to the normal operation mode using the operation mode switching unit 102 (step S30). In the process of step S30, in the case of an elevator in which light enters the car room 11 from outside the car 10, the elevator control unit 101 moves the car 10 to a boarding or alighting floor.

[0063] Next, the elevator control unit 101 cancels the notification that the elevator is in the diagnostic operation mode to the user or the external manager 120 such as the building owner via the hall terminal 104 or the communication device 105 (step S31). This completes the inspection work operation of the intercom 26.

[0064] As described above, the intercom 26 of this embodiment uses non-contact sensors, the illuminance sensor 31 and the photoelectric sensor 32. This allows the illuminance sensor 31 and the photoelectric sensor 32 to transmit information to the outside. As a result, the intercom 26 can be inspected remotely without an operator having to go to the site.

[0065] Moreover, the operation check process of the intercom 26 in the above-mentioned steps S17 to S27 is not limited to the example in which it is performed by the switching unit / operation check unit 42 of the car inside control unit 41. The operation check process of the intercom 26 may be performed by the elevator control unit 101 of the elevator control device 100, the external terminal 130, or a program on the cloud.

[0066] Furthermore, if the hall terminal 104 at each floor is operated by a user during the above-mentioned elevator diagnostic operation mode, the elevator control device 100 stops the diagnostic operation mode and switches to the normal operation mode. This makes it possible to prevent the convenience of the elevator from being reduced due to the inspection work of the intercom 26. The above-mentioned inspection work operation of the intercom is performed during times when the elevator is not used much, such as late at night or, in the case of an office building, on holidays.

[0067] The present invention is not limited to the embodiment described above and shown in the drawings, and various modifications can be made without departing from the spirit of the invention described in the claims.

[0068] The above-mentioned embodiment examples have described the configuration of the device and system in detail and specifically in order to explain the present invention in an easily understandable manner, and are not necessarily limited to those having all of the configurations described. In addition, it is possible to replace part of the configuration of the embodiment described here with the configuration of another embodiment, and it is also possible to add the configuration of another embodiment to the configuration of one embodiment. In addition, it is also possible to add, delete, or replace part of the configuration of the embodiment with other configurations.

[0069] In addition, the elevator configuration can be various types of elevators, including rope-type elevators such as 1:1 roping elevators and 2:1 roping elevators, hydraulic elevators, and other types of elevators.

[0070] In this specification, the words "parallel" and "orthogonal" are used, but these do not mean only "parallel" and "orthogonal" in the strict sense, but may also mean a "substantially parallel" or "substantially orthogonal" state that includes "parallel" and "orthogonal" and is within a range in which the respective functions can be exerted.
