(Structure of elevator)
First, the configuration of elevators embodiment according to the present invention. Figure 1 is an explanatory diagram showing a configuration of elevators embodiment according to 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, for example, in a building such as a multi-storey building.

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

  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 different from the place where the elevator 100 to be monitored is installed and apart from the place where the elevator 100 is installed. The management server computer 150 can be installed, for example, in a maintenance company that manages the maintenance of the elevator 100.

  The control panel 101 transmits a signal for reporting to the management server computer 150, for example. The control panel 101 outputs a signal for reporting when, for example, a failure is detected in the elevator 100, or when the operation mode of the elevator 100 is changed. 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 according to the received instruction to each unit included in the elevator 100.

  In the diagnostic operation, the control panel 101 outputs a signal for operating each part in a predetermined order to each part included in the elevator 100, and outputs a signal indicating whether or not each part normally operates 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 an instruction to execute the 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 the public voice network such as a telephone line, the telephone line is punctured in the event of an emergency such as a natural disaster such as an earthquake. It is possible to avoid delay in understanding the status of the elevator 100. Accordingly, in the situation where the elevator 100 is remotely monitored by 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 exchanges, not shown, such as a subscriber line exchange that accommodates telephone lines, a relay exchange that bundles the subscriber line exchanges, and a gateway exchange that connects to the telephone networks of other operators. . The public voice network is a well-known technique, and therefore its description is 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 includes a hoistway (not shown) that penetrates each floor in the building along the vertical direction. One hoistway is provided for each elevator 100. In the hoistway, a basket (carrying basket) 102 on which people and articles are mounted 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 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 (car 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 shock by utilizing the elastic force of a spring, or may be an oil-filled shock absorber that softens the shock by utilizing hydraulic resistance. The shock absorber 103 may also be provided on the ceiling surface of the hoistway.

  A door 104a is provided at a position (landing place) 104 corresponding to each floor in the hoistway. The door 104a provided at the landing 104 is locked by a device (not shown) called an interlock or the like. The interlock engages with the opening / closing mechanism of the door 102a of the basket 102 to release the lock only when the motor that opens and closes the door 102a of the basket 102 is driven when the basket 102 arrives at the stop floor. Thereby, only the door 104a provided in 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 landing 104. The operation panel 105 is equipped with a landing call button 105a, a display 105b for displaying the floor on which the basket 102 is located, and the like. The operation panels 105 each include 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 a rope 106. The rope 106 is slidably suspended on a pulley (not shown) and a hoisting machine (traction machine) 107, and the other end is connected to a counterweight 108. The rope 106 can be specifically realized by a wire made of steel, for example.

  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 top of the elevator 100 regardless of the presence or absence of a machine room. Alternatively, when the elevator 100 is a type without a machine room, the hoisting machine 107 may be provided in 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 drive-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 utilizing the frictional force (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 panel 101 can determine the rotational speed and the rotational position of the hoisting machine 107 based on the output signal from the encoder. The encoder may be, for example, an absolute encoder or an incremental encoder.

  The other end of a weight balance adjusting wire rope (or chain), one end of which is connected to the bottom of the counterweight 108, is connected to the bottom of the basket 102 (not shown). As a result, for example, in the elevator 100 installed in a high-rise building, due to the weight of the rope 106, an imbalance in the weight balance between the basket 102 side and the counterweight 108 side near the top floor and the bottom floor. It is possible to reliably prevent the rope 106 from slipping down from the sheave of the hoisting machine 107 due to the occurrence of the occurrence.

  The elevator 100 also 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, and stops the rotation of the hoisting machine 107 by using an electromagnetic force generated by energizing the coil which is drive-controlled by the control panel 101. 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 power supply is stopped due to a power failure or the like. As the electromagnetic brake 109, specifically, for example, a non-excitation actuated electromagnetic brake 109 is used that operates by the force of a spring to stop the rotation of the hoisting machine 107 when the coil is de-energized due to a power failure. be able to.

  The speed governor 110 detects that the speed of the basket 102 is exceeded. 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 rotating weight operates to open to the outer peripheral side of the governor pulley 110b when the rotating speed of the governor pulley 110b is fast, and closes to the inner peripheral side of the governor pulley 110b when the rotating speed of the governor pulley 110b is slow. Works like.

  The limit switch 111 includes a switch lever (not shown) that switches between supply and cutoff of power to the hoisting machine 107. The switch lever is positioned at a position where power is supplied to the hoisting machine 107 in normal times, and shuts off supply of power to the hoisting machine 107 when biased by the rotary weight of the speed 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 supply of power to the hoisting machine 107 when the ascending / descending speed of the basket 102 becomes a speed equal to or higher than the rated speed. So that the switch lever is urged. This allows the operation of the hoisting machine 107 to be stopped and the car 102 to be stopped when the car 102 exceeds the speed limit.

  Further, the elevator 100 may include 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. Since the emergency stop device can be easily realized by using various known techniques, description thereof will be omitted.

  The basket 102 is provided with an operation panel 102b. The operation panel 102b includes 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 a motor for opening / closing the door 102a, a door opening / closing sensor, an obstacle detection device, various sensors (see FIG. 3) such as a load sensor, and a buzzer (not shown). .

  An upper basket box 112 is provided above the basket 102. The upper basket box 112 is provided, for example, on the ceiling plate of the basket 102, that is, outside the basket 102. The basket upper box 112 accommodates an electric circuit including a power supply circuit and a control circuit. Various loads provided on the basket 102, such as various sensors such as a motor for opening and closing the operation panel 102b and the door 102a, a door opening / closing sensor, an obstacle detection device, a load sensor, and the like, are stored in the upper box 112 of the cage. 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, the motor rotates in the forward direction when the door 102a is opened and in the reverse direction when the door 102a is closed. The motor that opens and closes 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 micro switch 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 between, for example, a pair of doors 102a and is biased to project in the opening direction of the door 102a, or the safety shoes are inside the door 102a. It can be configured by a micro switch or the like that outputs a signal indicating that the object is caught between the pair of doors 102a when the door 102a is pushed into.

  The load sensor detects the loading load on the basket 102. Specifically, the load sensor can be realized by, for example, 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) on the basket 102 exceeds a predetermined mass such as the rated load (mass) on the basket 102.

(Example of basket 102 and each part provided in 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 unit provided in the basket 102.

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

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

  Further, the basket 102 is provided with a lighting device 204 for illuminating the space inside the basket 102 and a ventilation device (not shown). The lighting fixture 204 can be provided, for example, on the ceiling of the basket 102, 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 includes a fan (not shown) that is provided in the basket 102 and 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. Loads such as the lighting equipment 204 and the ventilation device are also connected to an electric circuit housed in the upper basket box 112, like the various loads provided in 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 restable of a connector pair configured by a resectorable and a plug that are joined so as to be separable from each other. The restable opening that realizes the stopper seat 205 is arranged inside the basket 102.

  As shown in FIG. 2, when the opening of the restable to realize the plug seat 205 is exposed in the basket 102, the plug seat 205 is arranged at a high position in the basket 102. It is preferable. By arranging the connector 205 exposed in the basket 102 at a high position in the basket 102 as described above, it is possible to prevent water droplets splashed from an umbrella or clothes in rainy weather and prevent mischief by a child. .

  The connector seat 205 further has a function of supplying power supplied from an electric circuit housed in the basket upper box 112 to an electric device 401 (see FIG. 4) connected to the connector seat 205. It is preferable. Specifically, for example, the function of supplying power to an electric device connected to the socket 205 is realized by using a restable that includes wiring for power supply in addition to wiring for signal transmission. can do.

  Restorable to realize the plugging seat 205 is preferably realized by a hot plug that can be inserted / removed during the operation of the electric device 401 connected to the restable. Further, it is preferable that the restable to realize the plug seat 205 can further supply power to the electric device 401 via the control circuit 320 (see FIG. 3).

  More specifically, the restable to realize the connector 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, the USB standard. This makes it possible to realize communication between the control circuit and the electric device and supply of power from the control circuit to the electric device only by connecting the electric device to the USB connector.

  The USB connector as a resectorable that realizes the connector seat 205 is realized by, for example, a restable 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 restable to realize the connector seat 205 is not limited to the USB interface connector (resctable), and for example, an IEEE 1394 connector, a PS / 2 connector, a D-Sub connector, a DIN connector, a coaxial connector, and other known connectors. 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 / multimedia data. Therefore, by providing an IEEE 1394 connector (resctable) to 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 is connected, and smooth communication with the electric device is performed. 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 method. Further, power can be supplied at 5V to an electric device connected to the control circuit via the PS / 2 connector. As a result, it is possible to drive the electric device connected to the control circuit via the PS / 2 connector (resctable).

  The D-Sub connector includes 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, screws. The number of terminals depends on the type of line. For example, in the case of a 9-pin D-sub connector, 5V power can be supplied using the 9th terminal (CI) which is not connected due to lack of signals in the cross cable. This makes it possible to drive an electric device connected to the control circuit via the D-Sub connector (resctable).

  The DIN connector has signal pins of 2 to 8 pins arranged inside a metal shield having a substantially circular ring shape. The metal shield in the DIN connector has a shape that is partially recessed toward 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 specifically, it can be realized by, for example, a BNC connector (Bayonet Neil-Concelman connector). By adopting a bayonet mechanism, it can be attached and detached by a simple operation and firmly fixed by the force of the built-in spring.

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

  One restorable for realizing the plug seat 205 may be provided in one basket 102, or a plurality of restables may be provided in one basket 102. When providing a restable to realize a plurality of plug-in seats 205 in one basket 102, the communication I / F connector may be of one type or of a plurality of types.

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

  When arranging the restable to realize the plug seat 205 so as to project inside the basket 102, an electric wire (cable) connecting the restable and the control circuit is used by using a coil spring or a tension spring. You may make it urge (pull) to the outer side of.

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

(Structure 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 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 preset predetermined AC voltage. 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 DC power source having the amplitude converted by the rectifying circuit 312. The smoothing circuit 313 smoothes the waveform distortion due to the AC component (ripple) included in the DC power source converted by the rectifying circuit 312.

  The constant voltage circuit 314 monitors the DC power source output from the smoothing circuit, compares the DC power source with a reference voltage, and controls the output voltage of the transistor when there is a difference. This can alleviate an unstable element in which the DC power source output from the smoothing circuit 313 changes according to the load connected to the power source circuit 310 and the environment, and the output DC power source voltage is kept constant. Can be kept.

Thereby, AC power can be supplied to each load directly or via the switch 331, the inverter 332, and the like. Alternatively, the DC power converted by the rectifier circuit can be supplied to each load.

  The load that receives power supply from the AC power supply or the DC power supply obtained by transforming the AC power supply is, for example, various types of motors 340 for opening and closing the door 102a, door opening / closing sensors, obstacle detection devices, load sensors, and the like. It can be realized by a load such as the sensor 341 or a buzzer. Further, the load that receives power supply from the AC power supply or the DC power supply obtained by transforming the AC power supply may include the switch 331 and the inverter 332.

  In FIG. 3, 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 has been described, but the present invention is not limited to this. 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 directly converting the AC input into a voltage is not required, and heat dissipation from the voltage stabilization circuit can be suppressed to reduce efficiency and heat generation. The allowable range of can be widened.

  The control circuit 320 is connected to each load provided on the control panel 101 and the basket 102. The control circuit 320 drives and controls each load provided in the basket 102 according to a downlink signal output from the control panel 101, and outputs an uplink signal corresponding to an output signal from each load provided in the basket 102, It is output to the control panel 101. Specifically, the control circuit 320 includes an input terminal 321, an output terminal 322, a CPU (Central Processing Unit) 323, a memory 324, and a communication I / F (InterFace) 325, which are connected to each other by a bus. can do.

  The input terminal 321 is a hardware interface that connects each load connected to the control circuit 320 and the CPU 323, receives an input of a signal output from each load connected to the control circuit 320, and receives an input. The signal is output to the CPU 323. The input terminal 321 is connected to the control panel 101.
