Hereinafter, preferred embodiments of the 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 diagram showing a configuration of an elevator according to an embodiment of the present invention.

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

Each part of the elevator 100 is driven and controlled by the control panel 101. The control panel 101 is connected to each part of the elevator 100, and for example, the control panel 101 outputs a signal for each part of the elevator 100, that is, a so-called “downstream signal”. Further, the control panel 101 receives, for example, a signal to the control panel 101 from each unit included in the elevator 100, that is, a so-called “upstream signal”.

Further, 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 in a remote place away from the place where the elevator 100 to be monitored 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 that is in charge of maintenance management of the elevator 100.

The control panel 101 transmits, for example, a signal for issuing an alarm to the management server computer 150. The control panel 101 outputs a signal for issuing a notification, 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 execution instruction of a diagnostic operation transmitted from the management server computer 150, and outputs a downlink signal corresponding to the received instruction to each unit included in the elevator 100.

In the diagnostic operation, a signal for operating each part in a predetermined order is output from the control panel 101 to each part provided in the elevator 100, and a signal indicating whether or not each part operates normally according to the output signal is output. It is realized by outputting from the control panel 101 to the management server computer 150. The management server computer 150 outputs, for example, an execution instruction of a diagnostic operation periodically (for example, every time the last day of the month arrives).

By connecting the control panel 101 and the management server computer 150 via the Internet instead of a public voice network such as a telephone line, the telephone line is punctured in an emergency such as an earthquake or other natural disaster. It is possible to avoid a delay in grasping the situation of the elevator 100. As a result, in a situation where the elevator 100 is remotely monitored using the management server computer 150, it is possible to take a prompt response 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 exchanges (not shown), such as a subscriber line exchange for accommodating telephone lines, a relay exchange for bundling subscriber line exchanges, and a barrier exchange for connecting to the telephone networks of other operators. .. Since the public voice network is a known technique, the description thereof will be omitted. By connecting the control panel 101 to the public voice network, voice communication between the intercom terminal device (see FIG. 2) and the management center can be realized.

The elevator 100 is provided with a hoistway (not shown) that penetrates each floor in the building along the vertical direction. One hoistway is provided for each elevator 100. A basket (riding basket) 102 for carrying people and goods is provided in the hoistway. The baskets 102 are provided one by one in one elevator 100, that is, one hoistway, and move up and down along the direction of the hoistway, that is, the vertical direction. The basket 102 is supported by a basket frame (not shown), and moves up and down together with the frame.

A guide rail (not shown) is provided on the side surface of the hoistway to guide the elevating position of the basket 102 (cage frame). At the bottom of the hoistway, a shock absorber 103 is provided to cushion the impact when the basket 102 falls and collides with the bottom surface. The shock absorber 103 may be a spring-type shock absorber that softens the impact by utilizing the elastic force of the spring, or may be an oil-filled shock absorber that softens the shock by utilizing the hydraulic resistance. The shock absorber 103 may also be provided on the ceiling surface of the hoistway.

Doors 104a are provided at positions (landings) 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 basket 102 to release the lock only when the motor for opening / closing the door 102a of the basket 102 is driven while the basket 102 has arrived at the stop floor. As a result, only the door 104a provided at the landing 104 on the floor where the basket 102 is located can be opened and closed in conjunction with each other.

An operation panel 105 is installed at each platform 104. The operation panel 105 is provided with a landing call button 105a, a display 105b for displaying the floor on which the basket 102 is located, and the like, respectively. Further, each of the operation panels 105 is provided with a control board 105c for the operation panel 105. Each operation panel 105 is connected to the control panel 101 via a control board 105c provided therein.

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

The hoisting machine 107 in the rope-type 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 uppermost part of the elevator 100 regardless of the presence or absence of 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.

The hoisting machine 107 is connected to the control panel 101 via, for example, an inverter (see FIG. 3), and is driven and controlled by the control panel 101 so as to stop the rotation on the floor where the basket 102 is stopped. In the rope-type elevator 100, the basket 102 is moved up and down by using the frictional force (traction) between the rope 106 and the pulley generated by driving the hoist 107.

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

The bottom of the basket 102 is connected to the other end of a wire rope (or chain) for weight balance adjustment, one end of which is connected to the bottom of the counterweight 108 (not shown). As a result, for example, in an elevator 100 installed in a high-rise building, the weight balance between the basket 102 side and the counterweight 108 side is imbalanced in the vicinity of the top floor or the bottom floor due to the weight of the rope 106. Can be reliably prevented from slipping off the rope 106 from the sheave of the hoist 107.

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

The electromagnetic brake 109 stops the rotation of the hoisting machine 107 when the power supply is stopped due to a power failure or the like. Specifically, the electromagnetic brake 109 uses a non-excitation actuated electromagnetic brake 109 that operates by the force of a spring to stop the rotation of the hoisting machine 107 when the energization of the coil is cut off, for example, in the event of a power failure. be able to.

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

The rotary weight operates according to the rotation 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 so as to open toward the outer peripheral side of the governor pulley 110b when the rotation speed of the governor pulley 110b is high, and closes to the inner peripheral side of the governor pulley 110b when the rotation speed of the governor pulley 110b is slow. Works like.

The limit switch 111 includes a switch lever (not shown) for switching power supply / cutoff to the hoisting machine 107. The switch lever is positioned at a position where power is supplied to the hoist 107 in normal times, and cuts off the power supply to the hoist 107 when urged by the rotary weight of the governor 110. Displace to position.

The rotary weight of the speed governor 110 is displaced to a position where the switch lever cuts off the power supply to the hoisting machine 107 when the ascending / descending speed of the basket 102 becomes a constant speed or higher with respect to the rated speed. As such, urge the switch lever. As a result, 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.

Further, the elevator 100 may be provided with an emergency stop device (not shown). The emergency stop device forces the operation of the basket 102 when the operation of the basket 102 and the operation of the governor rope 110a are different, that is, when the basket 102 is operating even though the governor rope 110a is stopped. Stop it. Since the emergency stop device can be easily realized by using various known techniques, the description thereof will be omitted.

The basket 102 is provided with an operation panel 102b. The operation panel 102b is provided with various operation buttons 201 and a display for displaying the floor on which the basket 102 is located (see FIG. 2). Further, the basket 102 is provided with various sensors (see FIG. 3) such as a motor for opening and closing the door 102a, a door opening / closing sensor, an obstacle detection device, a load sensor, and a buzzer (not shown). ..

A basket upper box 112 is provided on the upper part of the basket 102. The basket top box 11 is provided, for example, on the ceiling plate of the basket 102, that is, on the outside of the basket 102. The upper box 112 contains an electric circuit including a power supply circuit and a control circuit. Various loads provided on the basket 102, such as an operation panel 102b, a motor for opening and closing the door 102a, a door opening / closing sensor, an obstacle detection device, various sensors such as a load sensor, and a buzzer, are the electricity contained in the basket upper box 112. It is connected to the circuit. The electric circuit will be described later (see FIG. 3).

The motor that opens and closes the door 102a can rotate in the forward and reverse directions, for example, it 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 102a is provided, for example, on the ceiling plate of the basket 102. The door open / close sensor detects the open / closed state of the door 102a. The door open / close sensor can be realized by, for example, a microswitch or a photoelectric sensor whose output changes depending on whether the door 102a or the door 104a is in the open state or the closed state.

The obstacle detection device detects that an object such as a person is caught between the pair of doors 102a. Specifically, the obstacle detection device is provided, for example, between the pair of doors 102a and urged so as to project in the opening direction of the door 102a, or the safety shoe is inside the door 102a. It can be configured by a micro switch or the like that outputs a signal indicating that an object is caught between the pair of doors 102a when pushed into the door.

The load sensor detects the load on the basket 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 basket 102 and the basket 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 basket 102 exceeds a predetermined mass such as the rated load (mass) applied to the basket 102.

(Example of the basket 102 and each part provided in the basket 102)
Next, an example of the basket 102 and each part provided in the basket 102 will be described. FIG. 2 is an explanatory diagram showing an example of the basket 102 and each part provided in the basket 102.

In FIG. 2, the operation panel 102b provided on the basket 102 has an operation button 201 including a destination floor button for designating the destination floor of the basket 102, a door open / close button for instructing opening / closing of the door 102a, and the like, as described above. I have. Further, the operation panel 102b is provided with a display 202 for displaying the floor or the like on which the basket 102 is located. The operation panel 102b is, for example, a wall surface inside the basket 102 and is provided in the vicinity of the door 102a of the basket 102.

The operation panel 102b includes a control board for the operation panel 102b (see FIG. 3). The control board for the operation panel 102b generates, for example, a call signal corresponding to the input operation every time the operation panel 102b receives an input operation for the operation button 201 by a user of the elevator 100 or the like, and the generated call signal. Is output. Further, the control board for the operation panel 102b controls the display 202 to display the floor on which the basket 102 is located and display the moving direction.

The basket 102 is provided with an intercom terminal device 203. The terminal device 203 of the intercom includes a call button, a microphone, and a speaker (all of which are not shown). As shown in FIG. 2, the microphone and the speaker in the terminal device 203 of the intercom may be integrally incorporated in the operation panel 102b. The terminal device 203 of the intercom is connected to the control panel 101 via, for example, an electric circuit accommodated in the box 112 on the basket.

Further, the basket 102 is provided with a lighting fixture 204 for illuminating the space inside the basket 102 and a ventilation device (not shown). The lighting fixture 204 can be provided on the ceiling of the basket 102, for example, and specifically, various known light sources such as a light bulb (incandescent lamp), a fluorescent lamp, and an LED (Light Emitting Diode) can be used.

The ventilation device is provided in the basket 102 and includes a fan (not shown) that ventilates the air in the basket 102 through a slit (not shown) that communicates the inside and the outside of the basket 102. There is. The load of the lighting fixture 204, the ventilation device, and the like is also connected to the electric circuit accommodated in the box 112 on the basket, like the various loads provided on the basket 102.

Further, the basket 102 is provided with a plug seat 205. The connector seat 205 can be realized by, for example, a resectorable of a connector pair composed of a resectorable and a plug that are separably joined to each other. The opening of the resectorable that realizes the plug seat 205 is arranged inside the basket 102.

As shown in FIG. 2, when the opening of the resectorable that realizes the plug seat 205 is exposed in the basket 102, the plug seat 205 arranges the plug seat 205 at a high position in the basket 102. Is preferable. By arranging the plug seat 205 exposed in the basket 102 at a high position in the basket 102 in this way, it is possible to prevent water droplets flying from the umbrella or clothes from adhering to the basket 102 in rainy weather and to prevent mischief by children. ..

The plug seat 205 further has a function of supplying power supplied from the electric circuit accommodated in the upper box 112 to the electric device 401 (see FIG. 4) connected to the plug seat 205. Is preferable. Specifically, for example, by using a resectorable equipped with wiring for power supply in addition to wiring for signal transmission, a function of supplying power to an electric device connected to the plug seat 205 is realized. can do.

The resectorable that realizes the plug seat 205 is preferably realized by a hot plug that can be inserted and removed during the operation of the electric device 401 connected to the resectorable. Further, it is preferable that the resectorable that realizes the plug seat 205 can supply power to the electric device 401 via the control circuit 320 (see FIG. 3).

More specifically, the resectorable that realizes the plug seat 205 of the embodiment according to the present invention can be realized by a USB connector according to a predetermined interface standard, for example, a USB standard. As a result, it is possible to realize communication between the control circuit and the electric device and supply of power from the control circuit to the electric device simply by connecting the electric device to the USB connector.

The USB connector as a resectorable that realizes the plug seat 205 is realized by resectorable 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, the resectorable that realizes the plug seat 205 is not limited to the USB interface connector (resectorable), and is, for example, an IEEE 1394 connector, a PS / 2 connector, a D-Sub connector, a DIN connector, a coaxial connector, and other known ones. It may be realized by various communication connectors.

The IEEE 1394 connector is a high-speed serial bus standard and is suitable for transferring video and multimedia data. Therefore, by providing an IEEE 1394 connector (resectorable) in the basket 102, an electric device such as a display or a digital camera that transfers a large amount of data such as image data can be connected, and smooth communication with the electric device can be performed. 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 between the control circuit and the electric device in a synchronous serial manner. Further, power can be supplied at 5 V to the electric device connected to the control circuit via the PS / 2 connector. This makes it possible to drive an electric device connected to a control circuit via a PS / 2 connector (resectorable).

The D-Sub connector is a connector that is provided with a plurality of rod-shaped signal transmission terminals (pins) and is used for connecting a multi-core cable, and can be fixed to an electric device by 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, 5V power can be supplied by using the 9th terminal (CI) which is not connected because the signal is insufficient with the cross cable. This makes it possible to drive an electric device connected to a control circuit via a D-Sub connector (resectorable).

The DIN connector comprises 2-8 pin signal pins located inside a metal shield in a substantially round ring shape. The metal shield in the DIN connector has a partially recessed shape on the inner peripheral side, and this recess 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 Neil-Concelman connector). By adopting a bayonet mount, it can be attached and detached with a simple operation, and can be firmly fixed by the force of the built-in spring.

The coaxial connector is widely used in video equipment and communication equipment, and by realizing the resectorable that realizes the plug seat 205 by the coaxial connector, the surveillance camera can be used in the elevator 100 even after the elevator 100 is installed. It is possible to easily and quickly install an electric device that handles image data such as the above.

One resectorable that realizes the plug seat 205 may be provided in one basket 102, or a plurality of resectors may be provided in one basket 102. When a resectorable that realizes a plurality of plug seats 205 is provided in one basket 102, the number of types of communication I / F connectors may be one type or a plurality of types.

The resectorable that realizes the plug seat 205 is arranged so that, for example, the end portion of the resectorable that realizes the plug seat 205 is located on the same surface as the inner wall surface of the basket 102. Alternatively, the resectorable that realizes the plug seat 205 is arranged so as to project inside the basket 102 together with a part of the electric wire (cable) that connects the control circuit and the resectorable that realizes the plug seat 205, for example. You may.

When the resectorable that realizes the plug seat 205 is arranged so as to protrude inside the basket 102, the electric wire (cable) connecting the resectorable and the control circuit is connected to the basket 102 by using a coil spring, a tension spring, or the like. It may be urged (pulled) to the outside of the.

Thereby, when the resectorable that realizes the plug seat 205 is not used, the resectorable can be prevented from protruding inside the basket 102. In this case, it is preferable to provide a stopper (not shown) so that the resectorable pulled to the outside of the basket 102 does not come out to the outside of the basket 102. The stopper can be realized by, for example, a protrusion.

(Composition of electric circuit)
Next, the configuration of the electric circuit will be described. FIG. 3 is a block diagram showing the configuration of an 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 rectifier circuit 312, a smoothing circuit 313, and a constant voltage circuit 314.

The transformer 311 converts the AC voltage input from the AC power supply into a predetermined AC voltage. The transformer 311 converts the AC voltage input from the 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 oscillating DC power supply converted by the rectifying circuit 312. The smoothing circuit 313 smoothes the distortion of the waveform due to the AC component (ripple) included in the DC power supply converted by the rectifying circuit 312.

The constant voltage circuit 314 monitors the DC power supply output from the smoothing circuit, compares the DC power supply with the reference voltage, and controls the output voltage of the transistor when a difference occurs. As a result, the unstable factor that the DC power supply output from the smoothing circuit 313 changes according to the load connected to the power supply circuit 310 and the environment can be alleviated, and the voltage of the output DC power supply can be made constant. Can be kept.

Each load provided in the basket 102 is directly connected to an AC power source directly or via 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.
