Further, in the present invention, a car stop command operation unit for outputting a signal indicating that the movement of the basket is stopped to the control unit of the elevator may be provided.

In the present invention, the worker in the basket recognizes the basket movement information transmitted by the worker on the pit by the notification by the notification unit, and then moves the basket by the transmitted movement amount. Therefore, compared to the case where the control unit controls the movement of the basket based on the signal from the communication terminal, the number of steps until the basket moves increases, and as a result, it is easy to prevent the unexpected movement of the basket and it is safe. The sex can be significantly improved. However, it is of great significance for the safety of workers on the pit to assume a situation in which the basket behaves unexpectedly due to some problem and to be able to deal with such a situation.

According to this configuration, in an emergency, the communication terminal can directly output a signal to stop the car to the control unit that controls the movement of the car. Therefore, the basket can be quickly and urgently stopped in case of emergency, and the safety of workers on the pit can be solidified.

Further, in the present invention, the car operation prohibiting operation unit may be provided, which makes it impossible to move the basket in the basket unless the notification unit notifies the basket to move the basket for the short distance. ..

According to the above configuration, the movement operation of the basket in the basket becomes impossible unless the notification unit notifies the basket to move the basket for a short distance. Therefore, the safety can be further improved.

Further, in the present invention, a basket operation recovery operation unit for recovering the movement operation in the basket may be provided.

According to the above configuration, when the work on the pit is completed, the car moving operation in the car can be easily and instantly recovered.

It is a schematic block diagram of the elevator which concerns on one Embodiment of this invention. It is a perspective view of a communication terminal. It is a perspective view of the operation display device in a state where the opening / closing plate of a manual operation part is removed. It is a flowchart of an example of the control which a control panel executes when the worker on a pit performs the short-distance movement of a basket desired.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings. When a plurality of embodiments and modifications are included in the following, it is assumed from the beginning that a new embodiment is constructed by appropriately combining the characteristic portions thereof.

FIG. 1 is a schematic configuration diagram of an elevator 1 according to an embodiment of the present invention. As shown in FIG. 1, the elevator 1 includes a basket 11, a hoisting machine 12, a balance weight 13, a wire rope 14, a basket call button 15, a destination floor designation button 16, and a control panel 19 as a control unit. The control panel 19 and the hoisting machine 12 are provided in the machine room above the hoistway 20. If the elevator does not have a machine room, the control panel and hoisting machine are provided, for example, on a pit below the hoistway. The wire rope 14 is wound around the hoisting machine 12, and one end thereof is fixed to the upper part of the basket 11, while the other end thereof is fixed to the balance weight 13. The basket call button 15 is a button that calls the basket 11 and specifies the moving direction of the basket 11, and is provided at the landing 22 on all floors. Further, the destination floor designation button 16 is provided in the basket 11 for designating the destination floor of the basket 11. Each of the basket 11 and the balance weight 13 is guided by a guide rail provided in the hoistway 20. The control panel 19 that receives the signals from the basket call button 15 and the destination floor designation button 16 appropriately controls the rotation speed and the rotation direction of the motor of the hoisting machine 12, so that the basket 11 moves up and down in the hoistway 20.

The elevator 1 further includes a self-hand switching unit (not shown in FIG. 1) in the basket 11. For example, a destination floor operation display device (hereinafter, simply referred to as an operation display device) including a destination floor designation button 16 installed in the basket 11 has a manual operation unit opening / closing plate that can be removed using a key on the front side. When the manual operation unit opening / closing plate is removed, the manual operation unit located on the back side of the manual operation unit opening / closing plate can be exposed to the outside during normal operation of the basket 11. The self-hand switching unit forms a part of the manual operation unit and is included in the manual operation unit. The self-hand switching unit is connected to the control panel 19 via a control cable, and a worker or the like can output a signal to the control panel 19 via the self-hand switching unit. The destination floor designation button may be installed on a slide cover that can slide in the vertical direction, and the self-hand switching unit may be arranged on the back side of the slide cover during normal operation of the elevator. Further, the slide cover can be slid in the vertical direction from the normal position during normal operation of the elevator, and when the slide cover is slid, the self-hand switching portion may be exposed to the outside.

The self-hand switching unit is composed of, for example, a changeover switch. Workers and the like can switch between the automatic operation mode and the manual operation mode by using the self-hand switching unit. Here, when the automatic operation mode is selected, the control panel 19 controls the hoisting machine 12 and the like based on the operation of the basket call button 15 and the destination floor designation button 16, so that the automatic operation of the basket 11 is executed. NS. On the other hand, when the manual operation mode is selected, the operations of the basket call button 15 and the destination floor designation button 16 are invalidated, and the basket 11 is moved up and down according to the manual operation.

The control panel 19 includes a receiving unit (not shown) that receives a radio signal from the portable communication terminal 30. In the communication terminal 30, a worker 26 or the like performing maintenance on the bottom of the basket 11 on the pit tells the worker 27 or the like in the basket 11 that the basket 11 is 30 cm or less, 20 cm or less, 15 cm or less, or 10 cm or less. It is used when giving an instruction (request) to move a desired distance by a short distance.

FIG. 2 is a perspective view of the communication terminal 30. As shown in FIG. 2, the communication terminal 30 includes a number button from the "0" button to the "9" button, a "U" button, a "D" button, an "x" button, a start button 31, a release button 32, and a correction. The button 33, the basket stop button 34, and the display unit 35 are included. The display unit is composed of a liquid crystal display or the like. The plurality of buttons are an example of an operation unit for transmitting the amount of movement, and constitute an input unit of the communication terminal 30.

Although not shown, the communication terminal 30 has a control unit and a transmission unit including, for example, an antenna inside. The control unit receives the signals input by the plurality of buttons and outputs the signals to the control panel 19 via the transmission unit. Further, the control unit receives the signals input by the plurality of buttons and outputs the signals to the display unit 35 when necessary. The control unit is preferably configured by, for example, a microcomputer. The control unit includes a CPU (Central Processing Unit) and a storage unit such as a RAM (Random Access Memory) and a ROM (Read Only Memory). The CPU has a function of reading and executing a program or the like stored in advance in the storage unit. The RAM has a function of temporarily storing the read program and processing data. Further, the ROM has a function of storing a control program, a predetermined threshold value, and the like in advance.

The communication terminal 30 is used to transmit the basket movement information from the outside of the basket 11 of the elevator 1 to the inside of the basket 11. More specifically, the basket 11 is made to move a short distance of a desired distance of 30 cm or less. A signal to be notified to the notification unit in 11 is output to the control panel 19. The configuration of the notification unit will be described in detail later with reference to FIG. Next, the signal transmitted from the communication terminal 30 will be described. First, the start button 31 is pressed when the worker 26 on the pit desires to move the basket 11 over a short distance. Then, a signal indicating that the basket 11 is set to the short-distance movement mode for short-distance movement is output from the communication terminal 30 to the control panel 19, and the control panel 19 invalidates the operation of the basket movement by the operation unit in the basket 11. do. The start button 31 constitutes a basket operation prohibition operation unit.

Next, how to use other buttons will be described. For example, if the worker 26 on the pit wants to lower the basket 11 by 5 cm, in this case, the worker 26 presses the "5" button and the "D" button in this order. Then, the control unit causes the display unit 35 to display the wording "5 cm descent". This allows the user to determine if his input is correct. When the user determines that the input is correct and presses the start button 31, a signal indicating that the basket 11 is lowered by 5 cm is output from the communication terminal 30 to the control panel 19. On the other hand, when the user determines that the input is incorrect, he presses the correction button 33. As a result, the erroneous input is erased, and the display of "5 cm descent" by the display unit 35 is also erased. In this example, the start button 31 is used to transmit a signal indicating the movement of the car and a signal indicating the short-distance movement mode, but the operation unit that transmits the signal indicating the movement of the car is started. It may be provided separately from the button 31, and in this case, for example, the operation unit may be configured by a transmission button described as “transmission”.

Further, it is assumed that the worker 26 desires to lower the basket 11 by 3 cm repeatedly infinitely with an interval in between. In this case, the worker 26 presses the "3" button, the "x" button, and the "D" button in this order. Then, the control unit causes the display unit 35 to display the phrase "3 cm descent infinite repetition". This allows the user to determine if his input is correct. When the user determines that the input is correct and presses the start button 31, a signal indicating that the operation of lowering the basket 11 by 3 cm is repeated infinitely with an interval is output from the communication terminal 30 to the control panel 19. .. The operation when the user determines that the input is incorrect is the same as the operation described above.

As the interval time, for example, a time from 2 seconds to 10 seconds can be preferably adopted. Further, the communication terminal may be able to set the interval time. Then, for example, when the user inputs that the basket 11 is lowered by 4 cm infinitely with an interval of 3 seconds, the user inputs the "4" button, the "x" button, the "D" button, and the like. The "3" button may be input, or the display unit 35 may display "4 cm descent infinite repetition at 3 second intervals".

Further, it is assumed that the worker 26 desires to lower the basket 11 by 3 cm 6 times with an interval in between. In this case, the worker 26 presses the "3" button, the "x" button, the "6" button, and the "D" button in this order. Then, the control unit causes the display unit 35 to display the phrase "3 cm descent 6 times repeated". When the user determines that the input is correct and presses the start button 31, a signal indicating that the basket 11 is lowered by 3 cm is repeated 6 times is output from the communication terminal 30 to the control panel 19.

The release button 32 is used when the basket 11 is performing an operation of repeating a desired short-distance movement infinitely and the basket 11 reaches a desired height. When the release button 32 is pressed, a signal for stopping the basket 11 is output from the communication terminal 30 to the control panel 19, and the basket 11 can be stopped. The release button 32 constitutes a repeat operation release operation unit.

Further, the release button 32 also serves as a basket operation recovery operation unit. Specifically, the release button 32 is also used when the maintenance of the bottom of the basket 11 is completed and the short-distance movement mode is desired to be released. In such a case, when the release button 32 is pressed, a signal indicating that the short-distance movement mode is terminated is output from the communication terminal 30 to the control panel 19, the short-distance movement mode is terminated, and the control panel 19 is terminated. Revives the operation of moving the basket by the operation unit in the basket 11.

The basket stop button 34 is provided to stop the basket 11 in an emergency. The basket stop button 34 constitutes an operation unit for a basket stop command. When the car stop button 34 is pressed, a signal indicating that the car 11 is to be stopped urgently is output from the communication terminal 30 to the control panel 19, and the car 11 is urgently stopped by the control of the control panel 19. The basket stop button 34 is used when the basket 11 performs an unexpected operation or the like.

The function of the basket stop button 34 may be shared with the release button 32, or the basket stop button 34 may be omitted. Further, a case where the movement content is input by the operation unit shown in FIG. 2 has been described. However, the communication terminal may have an operation unit capable of inputting a desired distance of 30 cm or less and a short distance movement in a desired direction, and what is the name of each button, the order in which the buttons are pressed, the layout of the operation unit, and the like. It may be something like. Further, the operation unit does not have to have a button, and may be composed of a touch panel or the like.

Next, the lighting control of the operation display device regarding the movement of the basket by the control panel 19 will be described. The control panel 19 receives the above-mentioned signal from the communication terminal 30, and controls the lighting of the operation display device based on the received signal. FIG. 3 is a perspective view of the operation display device 40 in a state where the manual operation unit opening / closing plate is removed. With reference to FIG. 3, it is assumed that the control panel 19 receives a signal from the communication terminal 30 indicating that the basket 11 is raised by 5 cm. Then, the control panel 19 lights and controls the "5" button of the destination floor designation button 16 and the upper triangular button 41 indicating the ascent of the basket 11 in the operation display device 40 as an example of the notification unit. As a result, the worker 27 in the basket 11 can recognize that the worker 26 on the pit wants the basket 11 to rise by 5 cm.

Further, it is assumed that the control panel 19 receives a signal indicating that the basket 11 is lowered by 2 cm from the communication terminal 30 infinitely at intervals. Then, the control panel 19 lights and controls the "2" button of the destination floor designation button 16, the door closing operation operation unit 43 for causing the basket door to close, and the lower triangular button 42 indicating the lowering of the basket 11. .. The door closing operation operation unit 43 is used because its shape resembles the shape of "x". As a result, the worker 27 in the basket 11 can recognize that the worker 26 on the pit wants to lower the basket 11 by 2 cm repeatedly at intervals of an infinite number of times.

Further, it is assumed that the control panel 19 receives a signal indicating that the basket 11 is lowered by 3 cm from the communication terminal 30 four times at intervals. Then, the control panel 19 controls the blinking of the "3" button of the destination floor designation button 16, and also lowers the "4" button, the door closing operation operation unit 43 for causing the basket door to close, and the basket 11. The lower triangular button 42 is lit and controlled. The door closing operation operation unit 43 is lit and controlled because the shape of the door closing operation operation unit 43 resembles the shape of “x”. In this example, the number that is controlled to blink indicates the value related to the length. As a result, the worker 27 in the basket 11 can recognize that the worker 26 on the pit wants to lower the basket 11 by 3 cm four times at intervals.

In each of these examples, when the worker 27 in the basket 11 confirms the short-distance movement content of the basket 11 and then determines that the short-distance movement content is appropriate, the worker 27 moves the basket 11 upward. Presses, for example, the "U" button 45 included in the manual operation unit, and when moving the basket 11 downward, for example, presses the "D" button 46 included in the manual operation unit. When this operation is performed, a signal indicating that the operation displayed by the operation display device 40 is to be executed is output from the operation display device 40 to the control panel 19. Then, the control panel 19 that receives this signal receives a signal from a sensor that detects the position of the basket 11, for example, an encoder, a resolver, or a magnetic sensor installed in the motor of the hoisting machine 12. The control panel 19 controls the motor of the hoisting machine 12 based on the signal from the sensor, and moves the basket 11 as instructed by the operation display device 40. The "U" button 45 and the "D" button 46 are examples of the movement execution operation unit. When the worker 27 in the basket 11 determines that the displayed content is not appropriate, for example, the worker 27 outside the basket confirms the control content using the communication system installed in the basket 11. This ensures the safety of the worker 26 on the pit. Although not described in detail, in FIG. 3, the "self" button and the "hand" button are buttons for switching between the automatic operation mode and the manual operation board, and the "R" button is a RUN switch. The "R" button is provided to stop the basket 11 in an emergency.

FIG. 4 is a flowchart of an example of control executed by the control panel 19 when the worker on the pit executes the desired short-distance movement of the basket 11. Hereinafter, a typical control executed by the control panel 19 in the short-distance movement mode will be described with reference to FIG.

In the state where the elevator 1 is in the manual operation mode, the worker 26 on the pit operates the start button 31 of the communication terminal 30, and the control panel 19 signals the basket movement operation by the basket operation unit from the communication terminal 30. It is assumed that it is disabled unless there is. In this way, when the short-distance movement mode is started and the control is started, it is determined in step S1 whether or not the control panel 19 has received a signal indicating the short-distance movement of the basket 11 from the communication terminal 30. If a negative determination is made in step S1, step S1 is repeated. On the other hand, if an affirmative determination is made in step S1, the process proceeds to step S2, and the control panel 19 determines whether or not the received signal is a signal indicating that the short-distance movement is repeated infinitely.

If a negative determination is made in step S2, the process proceeds to step S3, the control panel 19 outputs a signal indicating that the operation display device 40 displays the short-distance movement of the content instructed by the communication terminal 30, and in step S4. , The operation display device 40 displays a short-distance movement by the method described above. After that, when the worker 27 in the basket who confirmed the display contents in step S5 determines that the control contents are appropriate, the worker 27 operates the operation display device 40, and the operation display device 40 moves to the control panel 19. A signal indicating that the short-distance movement of the displayed contents is to be executed is output. In the next step S6, the control panel 19 executes a short-distance movement of the basket 11 of the display contents based on the signal, and the operation display device 40 ends the display and proceeds to step S7.

In step S7, it is determined whether or not the control panel 19 has received a signal from the communication terminal 30 indicating the recovery of the basket movement operation by the basket operation unit installed in the basket 11. If an affirmative determination is made in step S7, the process proceeds to step S8, and the basket movement operation in the basket operation unit is restored by the control by the control panel 19, and the control ends. On the other hand, if a negative determination is made in step S7, step S1 and subsequent steps are repeated.

On the other hand, if an affirmative determination is made in step S2, the process proceeds to step S9, and the control panel 19 outputs a signal indicating an infinite number of repetitions with an interval of short-distance movement to the operation display device 40. In a subsequent step S10, a display representing infinite repetition of short-distance movement by the operation display device 40 is executed. Subsequently, in step S11, when the worker 27 in the basket who has confirmed the display content determines that the control content is appropriate, the worker 27 operates the operation display device 40, and the operation display device 40 operates the control panel 19. Outputs a signal that executes infinite repetition of the short-distance movement of the basket 11.

Subsequently, in step S12, the control panel 19 executes infinite repetition of the short-distance movement of the basket 11 based on the signal. In the next step S13, it is determined whether or not the control panel 19 has received a signal from the communication terminal 30 to stop the infinite repetition of the short-distance movement. If a negative determination is made in step S13, steps S12 and subsequent steps are repeated, and if an affirmative determination is made in step S13, the process proceeds to step S14. In step S14, the control panel 19 stops the movement of the basket 11, and ends the display indicating infinite repetition by the operation display device 40. When step S14 is completed, step S7 is executed.

As described above, the communication terminal 30 is used to transmit the basket movement information from the outside of the basket 11 of the elevator 1 to the inside of the basket 11. Further, the communication terminal 30 has a plurality of buttons (movement) for outputting to the control panel 19 a signal for notifying the notification unit in the basket 11 that the basket 11 is to move a desired distance of 30 cm or less and a short distance in a desired direction. Volume transmission operation unit) 31 to 34 are included.

Therefore, using the communication terminal 30, the worker 26 on the pit can tell the worker 27 in the basket 11 that the basket 11 is to be moved by a short distance of a desired distance. Therefore, for example, when the worker 26 on the pit wants to perform maintenance under the basket 11, for example, tightening the bolts under the basket 11, even in an environment where noise is present, for example, the basket 11 is several cm. It is possible to easily and surely convey to the worker 27 in the basket that he / she wants to be lowered. Therefore, there is no discrepancy in the recognition and communication of the amount of movement of the basket between the worker 26 on the pit and the worker 27 in the basket, and the safety of the worker 26 on the pit can be ensured.

Further, the movement amount transmission operation unit may be able to output a signal for notifying the operation display device 40 that the short-distance movement is repeatedly executed a plurality of times at intervals in the basket.

Rather than lowering the basket 11 all at once, the basket is moved to the desired position while ensuring safety by repeating short-distance movement multiple times at intervals (for example, an interval of time between 2 and 5 seconds). There is a request to stop it.

According to this configuration, the operation display device 40 can execute a display in which the short-distance movement is repeated a plurality of times at intervals in the basket 11. Therefore, even a complicated operation of the basket 11 such as repeating a short-distance movement a plurality of times at intervals can be accurately transmitted to the worker in the basket 11. As a result, by causing the basket 11 to perform such an operation, the safety of the worker 26 on the pit can be further improved.

Further, the movement amount transmission operation unit may be able to output a signal for notifying the operation display device 40 that the short-distance movement is repeatedly executed infinitely at intervals in the basket 11. Further, the communication terminal 30 may be provided with a release button 32 for canceling the repeated operation of the short-distance movement of the basket 11.

According to this configuration, by using the movement amount transmission operation unit, it is possible to repeatedly execute the short-distance movement in the basket 11 an infinite number of times at intervals. Further, when the basket 11 reaches a desired height, the movement of the basket can be stopped by using the release button 32. Therefore, the height of the basket 11 can be adjusted efficiently in a short time.

Further, the communication terminal 30 may include a basket stop button 34 for outputting a signal indicating that the movement of the basket 11 is stopped to the control panel 19.

In the present invention, the worker 27 in the basket 11 recognizes the basket movement information transmitted by the worker 26 on the pit by the notification by the operation display device 40, and then the movement transmitted only when the notification content is appropriate. The basket 11 will be moved by the amount. Therefore, compared to the case where the control panel controls the movement of the basket based on the signal from the communication terminal, the number of steps until the basket 11 moves increases, and as a result, it is easy to prevent the unexpected movement of the basket 11. , Safety can be significantly improved. However, it is of great significance for the safety of the worker 26 on the pit to assume a situation in which the basket 11 performs an unexpected operation due to some problem and to be able to deal with such a situation. According to this configuration, in an emergency, the communication terminal 30 can directly output a signal for stopping the basket 11 to the control panel 19 that controls the movement of the basket. Therefore, the basket can be quickly and urgently stopped in case of emergency, and the safety of the worker 26 on the pit can be solidified.

Further, the communication terminal 30 may include a start button 31 that makes it impossible to move the basket 11 in the basket 11 unless the operation display device 40 notifies the basket 11 that the basket 11 is to be moved for a short distance.

According to this configuration, unless the operation display device 40 notifies the basket 11 that the basket 11 is to be moved for a short distance, the movement operation of the basket 11 in the basket 11 becomes impossible. Therefore, the safety can be further improved.
