Description

This application relates to elevators.

Conventionally, for example, an elevator has a car having a car room and a car door, a door closing input unit that is arranged inside the car room and receives instruction information to close the car door, and a door closing input unit that is arranged inside the car room and has a car door. a destination input unit for inputting destination instruction information, a call input unit for inputting instruction information for calling a car to the landing, and a control device (for example, Patent Document 1). The control device controls the vertical movement of the car based on the information input to the destination input section and the call input section.

In the elevators according to Patent Documents 1 and 2, when a passenger in the car does not input to the destination input section, the traveling direction of the car is held and control is performed to prompt input to the destination input section. It is done. For example, in the elevators according to Patent Documents 1 and 2, it is determined whether or not a passenger has boarded the car due to load fluctuations, etc., and then when the car door is positioned at the closed position, whether or not there is an input to the destination input unit. is determined.

By the way, in the elevators according to Patent Documents 1 and 2, it is determined whether or not a passenger has boarded the car before the car door is positioned at the closed position. Therefore, when the car door is in the closed position, even if there are no passengers inside the car, the direction of travel of the car may be maintained, and control may be performed to prompt an input to the destination input unit. . This reduces, for example, the operating efficiency of the elevator.

When the first requirement is satisfied and the instruction information from the destination input unit is not acquired by the time the door closed position detection unit detects the closed position state, the traveling direction of the car is maintained. Direction holding control is executed, and the control device does not satisfy the first requirement and acquires instruction information from the destination input unit before the door closed position detection unit detects the closed position state. If not, the holding of the running direction of the car is released.

In addition, the elevator further includes a door closing input unit that is disposed inside the car room and receives instruction information for closing the car door, and the control device controls not only the first requirement but also the door closing position until the detection unit detects the closed position state and further satisfies the second requirement that the instruction information is acquired from the door closing input unit, and until the door closed position detection unit detects the closed position state. When the instruction information from the destination input unit is not acquired at the time, the control device executes the running direction holding control, the control device does not satisfy at least one of the first requirement and the second requirement, and The holding of the running direction of the car may be released when the instruction information from the destination input unit is not obtained until the door closed position detection unit detects the closed position state.

Further, in the elevator, in the running direction holding control, the control device controls the direction from the destination input unit until a first set time elapses after the door closed position detection unit detects the closed position state. When instruction information is not acquired, a door-opening operation for moving the car door to the open position is executed, and instruction information is acquired from the destination input unit, or after the door-opening operation, a second When the set time elapses, the door closing operation is executed to move the car door to the closed position, and the control device controls the door closed position detection unit until the closed position state is detected by the door closing operation. the direction of travel of the car is held, and the destination is input by the time the door closed position detection unit detects the closed position state due to the door closing operation. The configuration may be such that the holding of the running direction of the car is released when the instruction information from the unit is not acquired.

Further, in the elevator, if the control device has not acquired the instruction information from the call input unit and the destination input unit before the second set time elapses after the door opening operation, the When the door open holding operation for holding the car door in the open position is executed and instruction information is acquired from at least one of the call input unit and the destination input unit, or after the door open holding operation is executed, a third The door closing operation may be executed when the set time has elapsed.

Further, in the elevator, the third set time may be longer than the second set time.

Although not particularly limited, for example, one door opening input unit 10a and one door closing input unit 10b are provided. may have been

For example, as in the present embodiment, the hall input unit 12 includes an upward call input unit 12a for inputting instruction information for calling a car 2 traveling upward after arrival to the hall X3, and a car 2 traveling downward after arrival. and a downward call input unit 12b for inputting instruction information to call the elevator 2 to the hall X3.

For example, only one upward call input unit 12a may be provided in order to input only instruction information to travel upward after arrival. In order to input the instruction information of the destination, it may be provided as many as the number of destinations. In addition, only one down call input unit 12b may be provided, for example, in order to input only instruction information for traveling downward after arrival, or for example, only instruction information for traveling downward may be provided. In order to input destination instruction information as well, it may be provided as many times as the number of destinations.

Each of the input units 10, 10a-10c, 12, 12a-12b is not particularly limited, but may be, for example, a switch (push button switch, non-contact switch, etc.), touch panel, or the like. The output units 11 and 13 are not particularly limited, but may be, for example, a display unit (eg, display board, indicator lamp), an audio unit (eg, buzzer, speaker), or the like.

The door closed position detection unit 14 is not particularly limited, but may be, for example, a sensor (for example, a contact sensor, a proximity sensor) that detects the car door 2b positioned at the closed position. Further, the door open position detection unit 15 is not particularly limited, but may be, for example, a sensor (for example, a contact sensor or a proximity sensor) that detects the car door 2b positioned at the open position. The door closed position detection unit 14 and the door open position detection unit 15 may be, for example, different sensors, or may be, for example, a common sensor (for example, an encoder that detects the moving distance of the car door 2b). .

Although the load detection unit 16 is not particularly limited, for example, the load detection unit 16 may be configured to detect the absolute value of the load inside the car chamber 2a. The load detection unit 16 may be, for example, a weight sensor (for example, a load cell) arranged under the floor of the car compartment 2a, or various sensors (for example, a force sensor) arranged at the end of the car rope 6, for example. sensor, position sensor).

For example, as in the present embodiment, the control device 5 includes an acquisition unit 17 that acquires each information (data) from each unit 10, 10a to 10c, 12, 12a to 12b, and 14 to 16, and a memory that stores each information. A unit 18, a calculation unit 19 for calculating each piece of information, and a control unit 20 for controlling each unit 2c, 3, 11, 13 may be provided.

The control device 5 includes processors such as CPU and MPU (e.g., arithmetic unit 19, control unit 20), memories such as ROM and RAM (e.g., acquisition unit 17, storage unit 18), various interfaces (e.g., acquisition unit 17), etc. The units 17 to 20 of the control device 5 are realized by the processor executing the programs stored in the memory and by the cooperation of software and hardware.

The control device 5 may be composed of, for example, one device, or may be composed of, for example, a plurality of devices capable of communicating with each other. Specifically, the units 17 to 20 of the control device 5 may be provided in, for example, one device, or may be distributed and provided in a plurality of devices that can communicate with each other, for example.

For example, as in the present embodiment, the calculation unit 19 includes a door closed determination unit 19a that determines conditions when the car door 2b moves to the closed position, and a door position determination unit 19b that determines the position of the car door 2b. , a load determination unit 19c for determining the load inside the car chamber 2a, and a car travel calculation unit 19d for calculating travel (for example, travel direction and travel speed) of the car 2.

The door closing determination unit 19a may make determination based on instruction information from the door closing input unit 10b, for example. For example, the conditions when the car door 2b moves to the closed position are the first condition under which the acquisition unit 17 acquires the instruction information from the door closing input unit 10b, and the second condition under which the car door 2b is positioned at the open position for a predetermined time. In contrast to the presence of the two conditions, a configuration may be adopted in which the condition for moving the car door 2b to the closed position is determined based on the presence or absence of instruction information from the door closing input unit 10b.

The door position determination unit 19b may determine the position of the car door 2b based on the detections of the door closed position detection unit 14 and the door open position detection unit 15, for example. Although not particularly limited, for example, when the door closed position detection unit 14 detects the car door 2b, it is determined that the car door 2b is positioned at the closed position, and the door open position detection unit 15 detects the car door 2b. In this case, it is determined that the car door 2b is positioned at the open position, and when both the position detection units 14 and 15 do not detect the car door 2b, the car door 2b is positioned between the open position and the closed position. The configuration may be such that it is determined that the

The load determination unit 19c may determine the load inside the car chamber 2a based on the detection by the load detection unit 16, for example. Although not particularly limited, for example, the load inside the car room 2a may be calculated based on the detection of the load detection unit 16, and the presence or absence of the load corresponding to the passenger inside the car room 2a may be determined. .

The car travel calculation unit 19d may calculate travel (for example, travel direction, travel speed) of the car 2 based on information acquired from the input units 10, 10a to 10c, 12, 12a to 12b, for example. . For example, the car travel calculation unit 19d determines the travel direction of the car 2 based on predetermined information when a passenger in the car room 2a forgets to input instruction information to the destination input unit 10c. It may be determined whether or not to execute the running direction hold control to be held, or predetermined calculation and determination of the running direction hold control may be performed.

The configuration of the elevator 1 according to this embodiment is as described above. Next, control of the elevator 1 according to this embodiment will be described with reference to FIGS. 4 to 6. FIG. In addition, the structure of the elevator 1 is not limited to the above structure, and the control of the elevator 1 is not limited to the following control.

<Normal travel control>
First, the normal travel control, which is the control executed when the car 2 travels normally, will be described.

For example, the calculation unit 19 (specifically, the car travel calculation unit 19d) calculates travel of the car 2 in the vertical direction D3 based on the instruction information acquired from the destination input unit 10c and the call input units 12a and 12b. Alternatively, the control unit 20 may control traveling of the car 2 in the vertical direction D<b>3 by controlling the car driving unit 3 based on the calculation of the calculation unit 19 . Thus, the control device 5 controls the vertical travel of the car 2 based on the information acquired from the destination input section 10c and the call input sections 12a and 12b.

For example, the instruction information from the destination input unit 10c acquired by the acquisition unit 17 is stored (registered) in the storage unit 18 until the car 2 arrives at the boarding hall X3 of the destination. The instruction information from the input units 12a and 12b may be stored in the storage unit 18 until the car 2 traveling in the desired direction arrives at the hall X3.

For example, information from the destination input unit 10c that is not located on the traveling direction side of the car 2 may not be acquired by the acquisition unit 17 (disabled). As a result, for example, when the car 2 traveling upward is located on the fifth floor, the acquisition unit 17 does not acquire the instruction information input to the destination input unit 10c for the fifth floor and below.

In order to allow passengers to visually recognize that the instruction information is stored, the fact that the instruction information is stored may be output by the output units 11 and 13, for example. Although not particularly limited, for example, for input units 10c, 12a, and 12b to which stored instruction information is input, the buttons themselves and their surroundings of input units 10c, 12a, and 12b are output units 11 and 13. A light source may be used to emit light.

Then, the calculation unit 19 holds the traveling direction of the car 2 until all the instruction information from the destination input unit 10c is erased. That is, when all of the instruction information from the destination input unit 10c is erased, the calculation unit 19 releases the holding of the running direction of the car 2. FIG. It should be noted that even when the holding of the traveling direction of car 2 is released, the calculation unit 19 calculates the travel of car 2 based on the stored instruction information from the call input units 12a and 12b. may remain the same, or the direction of travel of car 2 may be reversed.

Here, the control that is executed when the car 2 arrives at the hall X3 in the normal travel control will be described with reference to FIG.

As shown in FIG. 4, when the car 2 arrives at a specific landing X3 (S1), the car door 2b is moved to the open position (S2), and after passengers get on and off, the car door 2b is moved to the closed position. (S3). If the instruction information from the door closing input unit 10b is acquired by the time the door closed position detection unit 14 detects the first closed position state ("Y" in S5), ("Y" in S4) ), the door open input requirement (second requirement) is established (S6). Accordingly, when the door opening input requirement (second requirement) is satisfied, there is a passenger who has input instruction information to the door closing input section 10b.

Further, when the door closed position detection unit 14 detects the first closed position state ("Y" in S7), and when the load detection unit 16 detects the load presence state ("Y" in S8), A load presence requirement (first requirement) is established (S9). As a result, when the load presence requirement (first requirement) is established, the load exists inside the car chamber 2a when the car door 2b is positioned at the closed position. The closed position state that occurs first after the car door 2b has moved to the open position after arriving at the landing X3 (S2) is referred to as a first closed position state (S5, S7).

Then, when the door closing input requirement (second requirement) and the load presence requirement (first requirement) are satisfied (S6, S9) and the instruction information from the destination input unit 10c has not been acquired (S10 "N"), there is a high possibility that a passenger is present inside the car room 2a and that the passenger has forgotten to enter the destination in the destination input unit 10c. Therefore, in such a case, running direction holding control is executed to hold the running direction of the car 2 . As a result, the running direction of the car 2 can be properly maintained.

Note that when the door closing input requirement (second requirement) and the load presence requirement (first requirement) are satisfied (S6, S9) and the instruction information from the destination input unit 10c is acquired (S10 "Y"), the normal traveling control is continued while the traveling direction of the car 2 is maintained (S13).

In addition, at least one of the door closing input requirement (second requirement) and the presence of load requirement (first requirement) is not satisfied ("N" in S4 and "Y" in S5, "Y" in S7 and "N" in S8). ), and also when the instruction information from the destination input unit 10c is acquired (“Y” in S11), the normal traveling control is continued while the traveling direction of the car 2 is maintained (S13 ).

On the other hand, at least one of the door closing input requirement (second requirement) and the presence of load requirement (first requirement) is not satisfied ("N" in S4 and "Y" in S5, "Y" in S7 and "Y" in S8 N"), and if the instruction information from the destination input unit 10c has not been acquired ("N" in S11), the holding of the running direction of the car 2 is released (S12), and then normal running control is performed. is continued (S13). As a result, since the running direction holding control is not executed unnecessarily, it is possible to suppress, for example, a decrease in the operating efficiency of the elevator 1 .

Specifically, for example, when a passenger leaves the car room 2a after inputting instruction information to the door closing input unit 10b and there is no passenger in the car room 2a, the presence of load requirement (first requirement) is not satisfied, the running direction holding control is not executed. Further, for example, when there are no passengers inside the car room 2a and there is only luggage, the door closing input requirement (second requirement) is not satisfied, so the traveling direction holding control is not executed.

<Travel direction retention control>
Next, the running maintenance control will be described with reference to FIGS. 5 and 6. FIG.

As shown in FIG. 5, first, for example, as in the present embodiment, a warning is output from the car output unit 11 to prompt passengers inside the car room 2a to input instruction information to the destination input unit 10c. (S21). The car output unit 11 may output the warning audibly, for example, by sound, or may output the warning visually, for example, by display.

Then, when instruction information from the destination input unit 10c is acquired from the time when the door closed position detection unit 14 detects the first closed position state until the first set time elapses ("Y" in S22). In ("Y" of S23), the traveling direction holding control is terminated while the traveling direction of the car 2 is held, and the normal traveling control is executed (S24). Although the first set time is not particularly limited, it may be, for example, 1 second to 5 seconds.

On the other hand, in a state where the instruction information from the destination input unit 10c has not been acquired ("N" in S23), the first set time has elapsed since the door closed position detection unit 14 detected the first closed position state. If it has passed ("Y" in S22), a door opening operation is performed to move the car door 2b to the open position (S25). This prompts the passengers inside the car room 2a to input instruction information to the destination input unit 10c.

Although not shown, in a state in which instruction information from the destination input unit 10c has not been acquired ("N" in S23), after the door closed position detection unit 14 detects the first closed position state, By the time the first set time elapses ("Y" in S22), for example, if instruction information is input to the door opening input unit 10a, the door opening operation may be performed (S25). Further, for example, in such a case, the acquisition unit 17 does not have to acquire the instruction information from the door opening input unit 10a (it may be invalidated).

Then, when the instruction information from the destination input unit 10c has been acquired from the time the door opening operation is performed (S25) until the second set time has elapsed ("Y" in S26) (S27 (Y)), the car door 2b is moved to the closed position (S28), and the running direction holding control is terminated while the running direction of the car 2 is held, and the normal running control is executed (S29). Although the second set time is not particularly limited, it may be, for example, 1 second to 5 seconds.

Thereby, when the instruction information from the destination input unit 10c is acquired, the car door 2b moves to the closed position before the second set time elapses. Therefore, since the car door 2b can be moved to the closed position in an appropriate time, it is possible, for example, to prevent the operating efficiency of the elevator 1 from deteriorating.

In addition, while the instruction information from the destination input unit 10c has not been acquired ("N" in S27), the second set time has passed ("Y" in S26), and the instruction information from the call input units 12a and 12b is acquired ("Y" in S30), a door closing operation is executed to move the car door 2b to the closed position (S31).

As a result, even if the instruction information from the destination input unit 10c has not been acquired, the car door 2b moves to the closed position after the second set time has elapsed. Therefore, since the car door 2b can be moved to the closed position in an appropriate time, it is possible, for example, to prevent the operating efficiency of the elevator 1 from deteriorating.

Although not shown, instruction information is input to the door closing input unit 10b, for example, after the door opening operation is executed (S25) and before the second set time elapses ("Y" in S26). If so, the door closing operation may be executed (S31). Further, for example, in such a case, the acquisition unit 17 does not have to acquire the instruction information from the door closing input unit 10b (it may be invalidated).

After the door closing operation is executed (S31), when the door closed position detection unit 14 detects the second closed position state ("Y" in S32), instruction information from the destination input unit 10c is obtained. If so ("Y" in S33), the traveling direction holding control is terminated while the traveling direction of the car 2 is held, and the normal traveling control is executed (S35). The closed position state that occurs first after the door closing operation is executed (S31) is referred to as the second closed position state (S32, S43 in FIG. 6).

Further, after the door closing operation is executed (S31), when the door closed position detection unit 14 detects the second closed position state ("Y" in S32), the instruction information from the destination input unit 10c is not yet received. If it is acquired ("N" in S33), the traveling direction holding of the car 2 is released (S34), the traveling direction holding control is terminated, and the normal traveling control is executed (S35). As a result, the traveling direction of the car 2 is not held unnecessarily, so that, for example, it is possible to prevent the operating efficiency of the elevator 1 from deteriorating.

On the other hand, while the instruction information from the destination input unit 10c has not been acquired ("N" in S27), the second set time has passed ("Y" in S26), and the call input units 12a and 12b is not yet acquired ("N" in S30), a door open holding operation for holding the car door 2b at the open position is executed (S36).

As a result, the car door 2b is held at the open position, so that the inside of the car room 2a can be visually recognized from the landing X3. Therefore, for example, when a passenger has a problem inside the car 2a (for example, the passenger is lying down), the inside of the car 2a can be easily seen from the landing X3.

Then, as shown in FIG. 6, instruction information from the destination input unit 10c is obtained after the door open holding operation is executed (S36) until the third set time elapses ("Y" in S37). If so ("Y" in S38), the car door 2b moves to the closed position (S39), and the running direction holding control is terminated while the running direction of the car 2 is held, and the normal running control is resumed. Executed (S40).

Further, when instruction information is acquired from the call input units 12a and 12b after the door open holding operation is executed (S36) and before the third set time elapses ("Y" in S37). ("N" in S38, "Y" in S41), the door closing operation is executed (S42).

As a result, when instruction information is acquired from the destination input unit 10c or the call input units 12a and 12b after the door open holding operation is executed, the car door 2b is closed before the third set time elapses. Move to position. Therefore, the car door 2b can be moved to the closed position in an appropriate time.

Although not shown, after the door open holding operation is executed (S36), until the third set time elapses ("Y" in S37), for example, the instruction information is input to the door closing input unit 10b. If input, the door closing operation may be executed (S42). Further, for example, in such a case, the acquisition unit 17 does not have to acquire the instruction information from the door closing input unit 10b (it may be invalidated).

On the other hand, if the instruction information from the destination input unit 10c and the call input units 12a and 12b has not been acquired ("N" in S38, "N" in S41), for example, it is not necessary to run the car 2. Therefore, the car door 2b is held at the open position, and after the third set time elapses ("Y" in S37), the door closing operation is executed (S42).

Note that, for example, the third set time may be longer than the second set time as in the present embodiment. Although not particularly limited, the third set time may be, for example, 30 seconds to 3 minutes. Also, although not particularly limited, the third set time may be, for example, five times or more the second set time, or may be, for example, ten times or more.

Thereby, when the instruction information from the destination input unit 10c and the call input units 12a and 12b has not been acquired, the car door 2b is held at the open position for the third set time. As a result, when there is no need to run the car 2, the state in which the inside of the car room 2a can be visually recognized from the landing X3 can be maintained for a sufficient time.

Then, after the door closing operation is executed (S42), when the door closed position detection unit 14 detects the second closed position state ("Y" in S43), instruction information from the destination input unit 10c is obtained. If so ("Y" in S44), the traveling direction holding control is terminated while the traveling direction of car 2 is held, and normal traveling control is executed (S46).

Further, after the door closing operation is executed (S42), when the door closed position detection unit 14 detects the second closed position state ("Y" in S43), the instruction information from the destination input unit 10c is not yet received. If it is acquired ("N" in S44), the traveling direction holding of car 2 is released (S45), the traveling direction holding control is terminated, and normal traveling control is executed (S46). This prevents the direction of travel from being unnecessarily retained.

As a result, the running direction holding control can be changed to control according to the current usage frequency. Therefore, for example, it is possible to prevent the operating efficiency of the elevator 1 from deteriorating due to the content of the running direction holding control being changed depending on whether the elevator 1 is used frequently or when it is not used frequently.

For example, the control device 5 may determine whether or not to execute the running direction holding control based on the current usage frequency. Further, for example, the control device 5 may determine whether or not to perform the door opening operation (S25 in FIG. 5) based on the current usage frequency. Further, for example, the control device 5 may determine whether or not to perform the operation for keeping the door open (S36 in FIGS. 5 and 6) based on the current usage frequency. Also, for example, the control device 5 may determine at least one of the first to third set times based on the current usage frequency.

Note that the control device 5 may determine the current frequency of use, for example, based on the number of start and stop times of the car 2 in the most recent predetermined period (eg, 10 minutes to 1 hour). Further, the control device 5 may determine the current frequency of use, for example, based on the accumulated running time of the car 2 in the most recent predetermined period.
