  Hereinafter, preferred embodiments of an elevator according to the present invention will be described in detail with reference to the accompanying drawings.

(Elevator configuration)
First, the configuration of the elevator according to the embodiment of the present invention will be described. FIG. 1 is an explanatory view showing a configuration of an elevator according to an embodiment of the present invention.

  In FIG. 1, an elevator 100 according to an embodiment of the present invention can be realized by, for example, a rope-type (traction-type) elevator 100. The elevator 100 is installed, for example, in a building such as a multi-storey building.

  The components included in the elevator 100 are drive-controlled by the control panel 101. The control panel 101 is connected to each component of the elevator 100. For example, the control panel 101 outputs a signal to each component of the elevator 100, that is, a so-called “down signal”. Further, control board 101 receives, for example, a signal to control board 101 from each part provided in elevator 100, a so-called “up signal”.

  Furthermore, the control panel 101 is connected to the management server computer 150 via a network such as the Internet. The management server computer 150 is installed at a remote place apart from the place where the elevator 100 is installed, which is different from the place where the elevator 100 to be monitored is installed. The management server computer 150 can be installed, for example, in a maintenance company responsible for maintenance of the elevator 100.

  The control panel 101 transmits, for example, an alerting signal to the management server computer 150. The control panel 101 outputs an alerting signal, for example, when a failure is detected in the elevator 100 or when the operation mode of the elevator 100 changes. Further, the control panel 101 receives various instructions such as an instruction to execute a diagnostic operation transmitted from the management server computer 150, and outputs a down signal corresponding to the received instruction to each unit provided in the elevator 100.

  In the diagnostic operation, the control panel 101 outputs a signal to operate each part in a predetermined order to each part included in the elevator 100, and a signal indicating whether the part operates normally according to the output signal It is realized by outputting from the control panel 101 to the management server computer 150. The management server computer 150, for example, outputs a diagnostic operation execution instruction periodically (for example, each time the last day of the month comes).

  By connecting the control panel 101 and the management server computer 150 not via a public voice network such as a telephone line but via the Internet, the telephone line may be punctured in an emergency such as when a natural disaster such as an earthquake occurs. It is possible to prevent the situation grasp of the elevator 100 from being delayed. In this way, in the situation where the elevator 100 is remotely monitored using the management server computer 150, it is possible to take prompt action when a problem occurs in the operation of the elevator 100.

  The control panel 101 may be further connected to a public voice network. Public voice networks include fixed telephone networks (public switched telephone networks) and mobile 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 exchange, and a gateway exchange connecting to a telephone network of another business operator. . The public voice network is a well-known technology and therefore the description thereof is omitted. By connecting the control panel 101 to a public voice network, voice communication can be realized between the interphone terminal (see FIG. 2) and the management center.

  The elevator 100 is provided with a hoistway (omitted from illustration) which penetrates each floor in the building along the vertical direction. One hoistway is provided for each elevator 100. In the hoistway, a car (car) 102 for carrying people and articles is provided. The cages 102 are provided one by one in one elevator 100, that is, in one hoistway, and move up and down along the direction of the hoistway, that is, the vertical direction. The cage 102 is supported by a cage frame (not shown), and moves up and down together with the frame.

  On the side surface of the hoistway, a guide rail (not shown) for guiding the elevation position of the cage 102 (car frame) is provided. A shock absorber 103 is provided at the bottom of the hoistway to cushion the impact when the cage 102 falls and collides with the bottom surface. The shock absorber 103 may be a spring-type shock absorber that uses an elastic force of a spring to cushion an impact, or may be an oil-filled shock absorber that uses an hydraulic resistance to cushion an impact. The shock absorber 103 may be provided also on the ceiling surface of the hoistway.

  Doors 104 a are provided at positions (halls) 104 corresponding to each floor in the hoistway. The door 104a provided at the landing 104 is locked by a device called an interlock or the like (not shown). The interlock engages with the opening / closing mechanism of the door 102a of the cage 102 to release the lock only when the motor for opening / closing the door 102a of the cage 102 is driven with the cage 102 arriving at the stop floor. Thereby, only the door 104a provided in the landing 104 in the floor where the basket 102 is located can be interlocked and opened and closed.

  A control panel 105 is installed at each of the landings 104. The operation panel 105 includes a hall call button 105a, a display 105b for displaying a floor on which the cage 102 is positioned, and the like. Further, each control panel 105 is provided with a control board 105 c for the control panel 105. Each control panel 105 is connected to the control panel 101 via a control board 105 c provided for each.

  The basket 102 is connected to one end of the rope 106. The rope 106 is hung on a pulley (not shown) and a hoisting machine (traction machine) 107 in a hoisting manner, and the other end is connected to the counterweight 108. The rope 106 can be specifically realized by, for example, a steel wire.

  The hoisting machine 107 in the rope elevator 100 is installed, for example, in a machine room provided at the top of the elevator 100. The hoisting machine 107 can be provided at the top of the elevator 100 with or without a machine room. Alternatively, when the elevator 100 is of a type without a machine room, the hoisting machine 107 may be provided at the lower part of the elevator 100.

  For example, the hoisting machine 107 is connected to the control board 101 via an inverter (see FIG. 3), and is driven and controlled by the control board 101 so as to stop the rotation on the floor where the cage 102 is to be stopped. In the rope elevator 100, the basket 102 is raised and lowered using the friction (traction) between the rope 106 and the pulley generated by driving the hoisting machine 107.

  The hoisting machine 107 includes an encoder (not shown), and the control board 101 can determine the rotational speed and rotational position of the hoisting machine 107 based on the output signal from the encoder. The encoder may use, for example, an absolute encoder or an incremental encoder.

  The other end of a weight balance adjusting wire rope (or chain) whose one end is connected to the bottom of the counterweight 108 is connected to the bottom of the cage 102 (not shown). Thus, for example, in the elevator 100 installed in a high-rise building, due to the weight of the rope 106, the imbalance of the weight balance between the basket 102 side and the counterweight 108 side in the vicinity of the top floor and the bottom floor. And the rope 106 can be reliably prevented from sliding off the sheave of the hoisting machine 107.

  The elevator 100 further includes an electromagnetic brake 109, a governor (a governor machine) 110, a limit switch 111, and the like. The electromagnetic brake 109 includes a coil, and is driven and controlled by the control panel 101 to stop the rotation of the hoisting machine 107 using an electromagnetic force generated by energizing the coil. The electromagnetic brake 109 can hold the state in which the rotation of the hoisting machine 107 is stopped.

  The electromagnetic brake 109 stops the rotation of the hoisting machine 107 when the supply of power is stopped due to a power failure or the like. Specifically, for example, the electromagnetic brake 109 uses a non-excitation operation type electromagnetic brake 109 that operates with the force of a spring to stop the rotation of the hoisting machine 107 when power to the coil is cut off, such as during a power failure. be able to.

  The governor 110 detects that the speed of the car 102 is excessive. The governor 110 can be realized by, for example, a centrifugal governor including a governor rope 110a, a governor pulley 110b, a rotary weight (not shown), and the like. In such a governor 110, the governor rope 110a interlocks with the operation of the cage 102. The governor pulley 110b rotates in conjunction with the operation of the governor rope 110a.

  The rotating weight operates in accordance with the rotational speed of the governor pulley 110b, that is, the magnitude of the centrifugal force caused by the rotation of the governor pulley 110b. Specifically, the rotary weight operates to open to the outer peripheral side of the governor pulley 110b when the rotational speed of the governor pulley 110b is high, and closes to the inner peripheral side of the governor pulley 110b when the rotational speed of the governor pulley 110b is low. To work.

  The limit switch 111 includes a switch lever (not shown) that switches supply / shutoff of power to the hoisting machine 107. The switch lever is located at a position where power is supplied to the hoisting machine 107 in a normal state, and shuts off the power supply to the hoisting machine 107 when energized by the rotary weight of the governor 110. Displace to position.

  The rotary weight of the speed governor 110 is displaced to a position at which the switch lever shuts off the supply of power to the hoisting machine 107 when the raising and lowering speed of the cage 102 becomes a speed higher than or equal to the rated speed As shown, press the switch lever. Thus, when the speed of the basket 102 is exceeded, the operation of the hoisting machine 107 can be stopped and the basket 102 can be stopped.

  Furthermore, the elevator 100 may be equipped with an emergency stop device (not shown). The emergency stop device forces the operation of the car 102 if the operation of the car 102 is different from the operation of the governor rope 110a, that is, if the car 102 is operating despite the governor rope 110a being stopped. Stop it. The emergency stop device can be easily realized using various known techniques, and thus the description thereof is omitted.

  The basket 102 is provided with an operation panel 102 b. The control panel 102b includes various operation buttons 201, a display for displaying a floor on which the cage 102 is positioned, and the like (see FIG. 2). In addition, the car 102 is provided with various sensors (see FIG. 3) such as a motor for opening and closing the door 102a, a door open / close sensor, an obstacle detection device, a load sensor, and a buzzer (not shown). .

  At the top of the basket 102, a basket upper box 112 is provided. The cage upper box 112 is provided, for example, on the ceiling plate of the cage 102, that is, on the outside of the cage 102. The cage upper box 112 accommodates an electric circuit including a power supply circuit, a control circuit, and the like. The various loads provided on the car 102 such as the control panel 102b, a motor for opening and closing the door 102a, door open / close sensors, obstacle detection devices, various sensors such as a load sensor, a buzzer, etc. Connected to the circuit. The electric circuit will be described later (see FIG. 3).

  The motor for opening and closing the door 102a is rotatable in the forward and reverse directions, for example, rotates in the forward direction when the door 102a is opened, and rotates in the reverse direction when the door 102a is closed. A motor for opening and closing the door 102 a is provided, for example, on the ceiling plate of the cage 102. The door open / close sensor detects the open / close state of the door 102a. The door open / close sensor can be realized by, for example, a micro switch or a photoelectric sensor whose output changes according to whether the door 102 a or the door 104 a is in the open state or in the closed state.

  The obstacle detection device detects a pinch of an object such as a person between the pair of doors 102a. Specifically, the obstacle detection device is provided, for example, between a pair of doors 102a and biased to project in the opening direction of the door 102a, and the safety shoes are inside the door 102a. When pushed in, it can be constituted by a micro switch or the like that outputs a signal indicating that a pinch of an object between the pair of doors 102a has been detected.

  The load sensor detects the load on the car 102. Specifically, the load sensor can be realized, for example, by a load cell. The load cell is provided, for example, between the bottom of the cage 102 and the cage frame. The buzzer outputs a buzzer sound according to the detection result of the load sensor. The buzzer outputs a buzzer sound when the load (mass) in the cage 102 exceeds a predetermined mass such as a rated load (mass) applied to the cage 102.

(An example of each part provided in the basket 102 and the basket 102)
Below, an example of each part provided in the cage | basket 102 and the cage | basket 102 is demonstrated. FIG. 2 is an explanatory view showing an example of the cage 102 and each part provided in the cage 102. As shown in FIG.

  In FIG. 2, the operation panel 102 b provided in the basket 102 includes the operation button 201 including the destination floor button for specifying the destination floor of the basket 102 and the door open / close button for instructing opening / closing of the door 102 a as described above. Have. In addition, the control panel 102b is provided with a display 202 for displaying a floor or the like where the car 102 is located. The control panel 102 b is, for example, a wall surface inside the cage 102 and is provided in the vicinity of the door 102 a of the cage 102.

  The control panel 102b includes a control board (see FIG. 3) for the control panel 102b. The control board for the control panel 102b generates, for example, a call signal generated according to the input operation each time the user of the elevator 100 or the like receives an input operation on the operation button 201 in the control panel 102b. Output In addition, the control board for the control panel 102b controls the display 202 to display the floor where the car 102 is located or to display the moving direction.

  The car 102 is provided with an interphone terminal device 203. The interphone terminal device 203 includes a call button, a microphone and a speaker (all are not shown). The microphone and the speaker in the terminal device 203 of the interphone may be integrally incorporated in the control panel 102b as shown in FIG. The interphone terminal device 203 is connected to the control panel 101, for example, via an electric circuit accommodated in the car upper box 112.

  In addition, the basket 102 is provided with a lighting fixture 204 for illuminating the space inside the basket 102 and a ventilator (not shown). The luminaire 204 can be provided, for example, on the ceiling of the cage 102. Specifically, various known light sources such as a light bulb (incandescent light), a fluorescent light, an LED (Light Emitting Diode), and the like can be used.

  The ventilation device is provided in the basket 102, and includes a fan (not shown) for ventilating the air in the basket 102 through a slit (not shown) communicating the inside and the outside of the basket 102. There is. The load such as the lighting fixture 204 and the ventilator is also connected to the electric circuit housed in the upper cage box 112, like the various loads provided to the cage 102.

  Further, the cage 102 is provided with a connection seat 205. The plugging seat 205 can be realized, for example, by the recessing of the connector pair configured by the recess and the recess, which can be separated from each other. The opening of the recess that realizes the plug seat 205 is disposed inside the cage 102.

  As shown in FIG. 2, when the opening of the recess for realizing the plugging seat 205 is exposed in the cage 102, the plugging seat 205 places the plugging seat 205 at a high position in the cage 102. Is preferred. In this manner, by arranging the socket 205 exposed in the cage 102 at a high position in the cage 102, it is possible to prevent water droplets flying from an umbrella or clothes from being attached when it rains, and to prevent children's mischief .

  The plugging seat 205 further has a function of supplying power supplied from the electric circuit accommodated in the upper cage box 112 to the electric device 401 (see FIG. 4) connected to the plugging seat 205. Is preferred. Specifically, for example, by using a resector capable of supplying a power supply wiring in addition to the signal transmission wiring, the function of supplying power to the electric device connected to the connector seat 205 is realized. can do.

  It is preferable that the resealable for realizing the plugging seat 205 be realized by a hot plug which can be inserted and removed during the operation of the electric device 401 connected to the resealable. Further, preferably, rescissable for realizing the plugging seat 205 can further supply power to the electric device 401 via the control circuit 320 (see FIG. 3).

  More specifically, rescissable for realizing the plugging seat 205 of the embodiment according to the present invention can be realized by a USB connector in accordance with a predetermined interface standard, for example, the USB standard. Thus, communication between the control circuit and the electric device and supply of power from the control circuit to the electric device can be realized only by connecting the electric device to the USB connector.

  For example, a USB connector as a resealable that realizes the connection seat 205 is realized by resuscable of various known USB connectors such as a USB Type-A connector, a Micro USB connector, a Micro USB Type-B connector, and a USB Type-C connector. be able to.

  Further, resuscable for realizing the connection seat 205 is not limited to the connector (rescueable) of the USB interface, and, for example, an IEEE 1394 connector, a PS / 2 connector, a D-Sub connector, a DIN connector, a coaxial connector, and other known devices. It may be realized by various communication connectors.

  The IEEE 1394 connector is a high-speed serial bus standard suitable for transfer of video and multimedia data. Therefore, by providing an IEEE 1394 connector (rescueable) in the basket 102, an electrical device such as a display or digital camera that performs large-capacity data transfer such as image data is connected, and smooth communication with the electrical device is achieved. It can be realized.

  The PS / 2 connector is a 6-pin input / output interface and is mounted on a PC / AT compatible machine. The PS / 2 connector can communicate in a synchronous serial manner between the control circuit and the electrical device. In addition, power can be supplied at 5 V to electrical devices connected to the control circuit via the PS / 2 connector. As a result, it is possible to drive an electrical device connected to the control circuit via the PS / 2 connector (rescueable).

  The D-Sub connector is a connector provided with a plurality of bar-like terminals (pins) for signal transmission and used for connection of a multi-core cable, and can be fixed to an electric device using, for example, a screw or the like. The number of terminals varies depending on the type of line. For example, in the case of a 9-pin D-sub connector, 5 V power can be supplied using a 9th terminal (CI) which is not connected because of a shortage of signals in the cross cable. Thus, the electric device connected to the control circuit can be driven via the D-Sub connector (rescueable).

  The DIN connector comprises 2-8 pins of signal pins located inside a substantially round, annular metal shield. The metal shield in the DIN connector is partially indented to the inner circumferential side, which can prevent the signal pin from entering the wrong jack.

  The coaxial connector is a connector of a coaxial cable, and can be specifically realized by, for example, a BNC connector (Bayonet Neill-Concelman connector). By adopting bayonet mount, it can be attached and detached with a simple operation and firmly fixed by the force of the built-in spring.

  Coaxial connectors are widely used in video equipment and communication equipment, and surveillance cameras for elevators 100 can be used even after the installation of elevator 100 by realizing resuscitation that realizes plug seat 205 by means of coaxial connectors. It is possible to easily and quickly install electrical devices that handle image data such as.

  One rescue may be provided in one cage 102, or a plurality of rescues may be provided in one cage 102. In the case where one basket 102 is provided with a resealable for realizing a plurality of connection seats 205, the communication I / F may have one type or a plurality of types of connectors.

  For example, the resealable for realizing the plugging seat 205 is disposed so that the end of the resizable capable of realizing the plugging seat 205 is flush with the inner wall surface of the cage 102. Alternatively, for example, the retractable for realizing the plugging seat 205 is disposed so as to project inside the cage 102 together with a part of the electric wire (cable) connecting the control circuit and the retractable for realizing the plugging seat 205. May be

  In the case where the resealable for realizing the plug-in seat 205 is disposed so as to protrude inside the cage 102, the electric wire (cable) for connecting the resealable and the control circuit is made of the cage 102 using a coil spring or a tension spring. May be biased (pulled) to the outside of the

  This makes it possible to prevent the interior of the resealable from projecting inside the cage 102 when the interior of the resealable that realizes the connection seat 205 is not used. In this case, it is preferable to provide a stopper (not shown) so that the resealable member pulled to the outside of the cage 102 does not come off to the outside of the cage 102. The stopper can be realized by, for example, a protrusion or the like.

(Configuration of electric circuit)
Next, the configuration of the electric circuit will be described. FIG. 3 is a block diagram showing the configuration of the electric circuit. In FIG. 3, the electric circuit 300 includes a power supply circuit 310 and a control circuit 320. The power supply circuit 310 is connected to an AC power supply, and includes a transformer 311, a rectification circuit 312, a smoothing circuit 313, and a constant voltage circuit 314.

  The transformer 311 converts an AC voltage input from an AC power supply into a predetermined AC voltage. The transformer 311 converts an AC voltage input from an AC power supply into a predetermined AC voltage set in advance. The rectifier circuit 312 converts the AC voltage transformed by the transformer 311 into a DC voltage. The smoothing circuit (filter) 313 linearly smoothes the amplitude DC power source converted by the rectifier circuit 312. The smoothing circuit 313 smoothes waveform distortion due to such AC components (ripples) included in the DC power supply converted by the rectifier circuit 312.

  The constant voltage circuit 314 monitors the DC power output from the smoothing circuit, and controls the output voltage of the transistor when there is a difference between the DC power and the reference voltage. Thereby, the unstable factor that the DC power output from smoothing circuit 313 changes according to the load connected to power supply circuit 310 or the environment can be alleviated, and the voltage of DC power output can be made constant. You can keep it.

  Each load provided in the cage 102 is connected to an AC power supply directly or through a switch 331, an inverter 332, a rectifier circuit 333, a transformer 334, and the like. The inverter 332 includes a converter circuit 332a, a capacitor 332b, and an inverter circuit 332c. Thereby, AC power can be supplied to each load directly or through the switch 331, the inverter 332, and the like. Alternatively, DC power converted by the rectifier circuit can be supplied to each load.

  Specifically, for example, various loads such as a motor 340 for opening and closing the door 102a, a door opening / closing sensor, an obstacle detection device, and a load sensor receive power supply from the AC power supply or DC power supply obtained by transforming the AC power supply. This can be realized by the load of the sensor 341 or the buzzer. Further, a load receiving power supply from an AC power supply or a DC power supply obtained by transforming the AC power supply may include the switch 331 and the inverter 332.

  Although the power supply circuit 310 according to the series power supply having a very high stability because the ripple content rate is small and the noise is small in FIG. 3 has been described, it is not limited thereto. For example, a switching power supply may be used instead of the series power supply. By using a switching power supply instead of a series power supply, a large transformer for direct voltage conversion of AC input is not required, and heat radiation of the voltage stabilization circuit can be suppressed to suppress a drop in efficiency and heat generation.
