Description

  The present invention relates to an elevator operation control apparatus and operation method, and more particularly, to an elevator operation control apparatus and operation method that allows a passenger to go to a destination floor without operating a button.

The basic operation common to conventional elevators is as follows.
Passengers in the hall press the operation button installed in the hall and call the car to the floor where they are. When the car arrives, the door opens, the passenger gets into the car, and presses the button on the destination floor with the operation panel in the car. When the door is closed, the car moves up and down toward the target floor. When you arrive at the target floor and the elevator doors open and passengers get off, the elevator is on standby, waiting for the next car call.

  As described above, the conventional elevator is operated based on the button operation of the operation panel provided by the passenger in the hall or the car. For this reason, the operation of the operation panel of the elevator hall or the operation panel in the car may not be easy for visually impaired persons and passengers who are not guided in the manner of operation such as the elderly.

Therefore, for example, Japanese Patent Laid-Open No. 9-194150 discloses a conventional elevator operation control device that does not require button operation for the disabled or elderly to make the elevator easier to use.
JP-A-9-194150

  In a conventional elevator, when a passenger is in the car and another passenger presses the button on the control panel of the elevator hall, the car is called to the floor and the elevator is held with the passenger inside. Will begin to move. The passenger inside goes to the floor that he / she does not want to go to without specifying the destination floor by operating himself / herself. Moreover, for the elevator management side, it is easy to go to the floor that some passengers do not want to use.

  In recent years, two-way elevators that can enter and exit the car from both the front and back have been developed. In this type of two-way elevator, there is a distinction between front and back on the destination floor, but for passengers unfamiliar with two-way elevators, it may be confusing which button to press.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an elevator operation control device that can solve the problems of the prior art and can go to the destination floor by fully automatic operation without operating a button. .

  In order to achieve the above object, the invention according to claim 1 is an elevator operation control apparatus for automatically operating a car between a plurality of designated floors designated in advance, and whether or not passengers are present in a hall on the designated floor. First passenger detection means for detecting the vehicle, second passenger detection means comprising a plurality of photoelectric elements for detecting the presence or absence of a passenger when the optical axis is interrupted by the passenger, in the car, An operation control device for automatically generating a hall call and a car call according to a predetermined sequence on the basis of detection signals given from one passenger detection means and a second passenger detection means, and for automatically operating the car. It is characterized by that.

    The second passenger detection means is preferably arranged by combining photoelectric elements that emit light rays in parallel and obliquely between the side walls facing each other with the side of the car door being the front.

    The second passenger detection means may use a motion sensor that emits light in one direction from one side wall to the other side wall.

  ADVANTAGE OF THE INVENTION According to this invention, the elevator fully automatic driving | operation which enables going to the destination floor without request | requiring the passenger | crew's button operation of a control panel is realizable.

Hereinafter, an embodiment of an elevator operation control apparatus according to the present invention will be described with reference to the accompanying drawings.
First embodiment
FIG. 1 is a plan view of an elevator car to which the present invention is applied. 2 is a view taken in the direction of arrows II-II in FIG. The entire cab is indicated by reference numeral 10.

  1 and 2, reference numeral 11 indicates a car floor. The side plate 12 of the car room forms left and right side walls toward the front of the car room. Reference numeral 14 denotes a car room ceiling, on which an illumination device 14a for illuminating the car room is arranged. In this embodiment, a car door (not shown) is arranged on both the front and back of the car room 10. Reference numeral 15 is a car operation panel.

  FIG. 3 shows an elevator hoistway 16. In the elevator of this embodiment, the hoistway 16 extends from the first floor to the second floor of the building, and the car 10 moves up and down between the first floor and the second floor. Hall operation panels 20 and 21 are arranged at the landings on the first floor and the second floor, respectively, and human sensors 22 and 23 for detecting the presence or absence of passengers are provided below the floor of the hall. In FIG. 3, the left side is the front side and the right side is the back side between the hoistways 16 in the landing. Passengers get on and off the car 10 from the front of the landing.

  In the present embodiment, the car 10 is provided with a plurality of photoelectric sensors for detecting the presence or absence of passengers as follows. 1 and 2, reference numerals 30a to 30h denote light projecting portions of the photoelectric sensor, and 32a to 32h denote light receiving portions of the photoelectric sensor. The light projecting units 30a to 30h of the photoelectric sensor emit light toward the light receiving units 32a to 32h facing each other, and when the optical axis is blocked by the passenger's body, at least one of the light receiving units 32a to 32h Since the light beam does not reach, this makes it possible to detect the presence of a passenger. On the other hand, if the light beam reaches all the light receiving portions 32a to 32h, it means that no passenger is present in the car room.

  By the way, it is not known in which position the passenger entering the car 10 is in the car room. In addition, the number of passengers may be only one, or may be multiple. In addition, passengers can be children, adults with large physiques, or people with thin figures.

  Therefore, in the present embodiment, a photoelectric sensor having a parallel optical axis and a photoelectric sensor having an oblique optical axis are arranged in combination so that the presence or absence of a passenger can be reliably detected. For example, in FIG. 1, a photoelectric sensor composed of a pair of light projecting unit 30a and light receiving unit 32a and a photoelectric sensor composed of a pair of light projecting unit 30g and light receiving unit 32g have parallel optical axes. In contrast, a photoelectric sensor composed of a pair of the light projecting units 30b to 30f and 30h and the light receiving units 32b to 326f and 32h changes the tilt angle of the light projecting units 30b to 30f and 30h, and sets the optical axis obliquely. is doing. Each optical axis is on a horizontal plane and intersects with another optical axis, and the arrangement of such photoelectric sensors prevents a blind spot from being generated in the passenger car 10.

  Furthermore, as shown in FIG. 1, the projectors 32 a to 32 g are attached to a side plate 16 called a cargo slide just above the car floor, which corresponds to the height of a passenger's foot. Although not shown in the drawings, the light receiving portions 32b to 32f are also attached at the same height to the opposite cargo supports.

  Next, FIG. 4 is a block diagram of an elevator control system.

  In FIG. 4, reference numeral 40 indicates a control panel that controls the overall operation of the elevator, and reference numeral 41 indicates a motor of the hoisting machine. In this embodiment, it is assumed that a car operates between the first floor and the second floor in a building where an elevator is installed. At the platforms on each floor, operation panels 20 and 21 with operation buttons are installed. These operation panels 20 and 21 are connected to the control panel 40. The car operation panel 15 is connected to the control panel 40 via a tail cord. Detection signals from the human sensors 22 and 23 provided at the landings on the first floor and the second floor and the light receiving portions 32a to 32h of the photoelectric sensors in the car are introduced into the control panel 40.

  Next, FIG. 5 shows a flowchart of elevator operation control executed by the control panel 40. Hereinafter, the operation control of the elevator will be described in detail with reference to FIGS. 5 and 3.

  In FIG. 5, in the first step S1, it is determined whether or not the human sensor 22 on the first floor has detected a passenger. As a result of the determination in step S1, the process when the passenger is on the first floor is step S2 to step S20, and the process when the passenger is on the second floor is the process after step S30.

  Since the elevator is in operation, when the passenger on the first floor is detected by the human sensor 22 on the first floor, the process during the inspection in step S2 is skipped and the process proceeds to step S4. If the car 10 is waiting on the first floor, an arrival guidance sound is heard at the landing on the first floor, and the hold door and the car door are opened (step S6). If the car 10 is waiting on the second floor in step S4, the first floor hall call is automatically registered (step S5), so the car 10 is called on the first floor and the door is opened.

  For example, since the door is open for 15 seconds (step S7), when the passenger gets into the car 10, the optical sensors 30a to 30h and 32a to 32h in the car 10 are blocked, so the passenger gets in Is detected (step S8). Then, the second floor car call is automatically registered, the door is closed, and the car 10 starts moving to the second floor (steps S9 and S10). When the car 10 arrives on the second floor, the door is opened together with voice guidance (step S11), and the passenger can get off the car 10.

  If the passenger detected at the first floor platform does not get on the car and the presence of the passenger cannot be detected, the door closes (step S17), and the car 10 continues to stand by on the first floor (step S18). Return to step S1.

  After the passenger gets down to the second floor in step S11, the car door is kept open for 15 seconds (step S12), so that the passenger who wants to go to the first floor from the second floor boarding station 10 Is detected by the photoelectric sensors 30a to 30h and 32a to 32h in the car (yes in step S13). Thereby, the first floor car call is automatically registered, the door is closed, and the car 10 starts moving to the first floor (steps S14 and S15). When the car 10 arrives at the first floor, the door opens with voice guidance (step S16), and the passenger can get off to the first floor platform.

  In step S13, if no passenger can be detected in the car 10, the door is closed and the second floor is kept on standby (steps S19 and S20).

  The above description is a sequence during which the passenger rides from the first floor and the car 10 goes from the first floor to the second floor and back to the first floor. However, if the passenger gets from the second floor, the first step S1 From step S30 to step S30.

  If a passenger on the second floor is detected by the human sensor 23 on the second floor (yes in step S30), the process skips step S31 and proceeds to step S32. If the car 10 is waiting on the second floor, an arrival guidance sound is generated at the second floor landing, and the hold door and the car door are opened (step S33). If the car 10 is waiting on the first floor, the second floor hall call is automatically registered (step S34), so the car 10 is called on the second floor and the door is opened.

  Therefore, since the door is open for 15 seconds (step S35), when the passenger gets into the car 10, the optical sensors 30a to 30h and 32a to 32h in the car 10 are blocked, so the passenger gets in Is detected (yes in step S36). Then, the first floor car call is automatically registered, the door is closed, and the car 10 starts moving to the first floor (steps S37 and S38). When the car 10 arrives at the first floor, the door is opened together with voice guidance (step S39), and the passenger can get off from the car 10 to the first floor platform.

  In addition, since the passenger detected at the second floor landing did not get on the car, when the presence of the passenger could not be detected, the door is closed (step S40), the process returns to step S1, and the car 10 is left on the second floor. Continue waiting.

  After the passenger gets down to the first floor in step S39, the car door remains open for 15 seconds (step S42), so that the passenger who wants to go to the second floor from the first floor platform 10 Is detected by the photoelectric sensors 30a to 30h and 32a to 32h in the car 10 (yes in step S43). Thus, the second floor car call is automatically registered, the door is closed, and the car 10 starts moving to the second floor (step S47). When the car 10 arrives on the second floor, the door opens with voice guidance (step S48), and the passenger can get off to the second floor landing.

  In step S43, if the passenger cannot be detected in the car 10, the door is closed and the first floor is kept on standby (steps S50 and S51).

  As described above, the elevator can be operated fully automatically without the need for passengers to operate the operation panel and the car operation panel at the landing. In addition, the presence or absence of passengers in the car can be assured regardless of the situation of passengers, etc., by arranging a combination of photoelectric sensors with parallel optical axes and oblique photoelectric sensors. Therefore, automatic operation of the elevator can be reliably executed without making the passengers aware of the operation panel, sensors, and the like.

Second embodiment
Next, a second embodiment of the present invention will be described with reference to the flowchart of FIG. This second embodiment is an embodiment for controlling the sequence of one-way completion operation of a two-way elevator having landings on the front and rear surfaces between the first floor and the second floor.

  As shown in FIG. 7, in the case of one-way completion operation, a front landing and a rear landing are provided on the first floor and the second floor, respectively. Human sensors 22a and 22b are installed on the floors of the front and rear landings on the first floor, and human sensors 23a and 23b are installed on the floors of the front and rear landings of the second floor. The car is provided with car doors on the front and back, corresponding to the front landing and the rear landing. As the one-way completion operation, a one-way completion operation between the first floor front landing and the second floor rear landing can be considered as a one-way completion operation between the first floor rear landing and the second floor front landing.

  Hereinafter, the one-way completion operation will be described with reference to the flowchart of FIG.

  In FIG. 6, first step S100 determines whether or not the human sensor 22a has detected a passenger at the front landing on the first floor. As a result of the determination in step S100, when the passenger is in front of the first floor, the process of performing one-way completion operation with the back of the second floor is step S102 to step S122, and the passenger is in front of the second floor The process of performing a one-way completion operation with the back of the first floor is the process after step S130.

  First, when a passenger is detected by the human sensor 22a at the first floor front landing, the process proceeds to step S104 (the process during inspection in step S102 is skipped). When the car 10 is waiting on the first floor, an arrival guidance sound is generated at the front landing on the first floor, and the hold door and the car door are opened (step S106). If the car 10 is waiting on the second floor, the first-floor hall call is automatically registered (step S105), so the car 10 is called on the first floor and the front landing door is opened.

  Therefore, when the passenger enters the car 10 while the door is open (step S107), the optical axes of the photoelectric sensors 30a to 30h and 32a to 32h in the car 10 are blocked, so that the passenger has entered the car. It is detected (step S108). Then, the second floor car call is automatically registered, the door is closed, and the car 10 starts moving to the second floor (steps S109 and S110). When the car 10 arrives at the second floor, the back door is opened together with voice guidance (step S111), and the passenger can get off the car 10 to the second floor rear landing.

  In addition, since the passenger detected at the front landing on the first floor did not get on the car, if the presence of the passenger could not be detected at step S108, the door is closed (step S117), and the car 10 stands by on the first floor. (Step S118).

  After the passenger has entered the second floor rear landing at step S111, the car door remains open for 15 seconds (step S112), and the passenger is going to go to the first floor front from the second floor rear landing. Is detected by the photoelectric sensors 30a to 30h and 32a to 32h in the car (Yes in step S113). Thus, the first floor car call is automatically registered, the door is closed, and the car 10 starts moving to the first floor (steps S114 and S115). When the car 10 arrives at the first floor, the door on the front side of the first floor opens together with voice guidance (step S116), and the passenger can get off to the first floor front landing.

  In step S113, if the passenger cannot be detected in the car 10, the door is closed and the second floor is kept on standby (steps S119 and S120). And if a passenger is detected in the 2nd floor back platform, it will return to step S111 and will repeat a step after step S111 and will carry a passenger to the 1st floor front.

  Next, the processing in step S130 and subsequent steps for performing a one-way completion operation between the front of the second floor and the back of the first floor is similarly performed without requiring the passenger to operate the operation panel.

  When a passenger at the second floor front landing is detected by the second floor human sensor 23a (yes in step S130), if the car 10 is waiting on the second floor (yes in step S132), the front of the second floor At the platform, an arrival guidance sound is generated and the hold door and the car door are opened (step S133). When the car 10 is waiting on the first floor (No in step S132), the second floor hall call is automatically registered (step S134), so the car 10 is called on the second floor and the second floor front landing The side door opens.

  Therefore, when the passenger enters the car 10 while the door is open (step S135), the optical axes of the photoelectric sensors 30a to 30h and 32a to 32h in the car 10 are blocked, so that the passenger has entered the car. It is detected (yes in step S136). Then, the first floor car call is automatically registered, the door is closed, and the car 10 starts moving to the first floor (steps S137 and S138). When the car 10 arrives at the first floor, the door on the back side of the first floor opens with voice guidance (step S139), and the passenger can get out of the car 10.

  In addition, since the passenger detected at the 2nd floor front landing did not get on the car 10, when the presence of the passenger could not be detected, the door is closed (step S141), and the car 10 continues to stand by on the 2nd floor. (Step S142), the process returns to Step S1.

  After the passenger gets off to the first floor rear landing at step S139, the door of the car 10 is kept open for 15 seconds (step S42), and the passenger is going to go to the second floor from the first floor rear landing. When the car enters the car 10, it is detected by a sensor in the car (yes in step S143). As a result, the second floor car call is automatically registered (step S144), the door is closed, and the car 10 starts moving to the second floor (step S145). When the car 10 arrives at the second floor, the door on the second floor front side opens with voice guidance (step S146), and the passenger can get off to the second floor front landing.

  If no passenger is detected in the car 10 in step S143, the door is closed and the vehicle is on standby on the first floor (steps S147 and S148). And if a passenger is detected in the 1st floor back platform (step S149), it will return to step S139 and will repeat a step after step S139 and will carry a passenger to the 2nd floor front.

  Next, FIG. 8 is an embodiment in which a plurality of motion sensors 38a to 38g for emitting infrared rays in one direction from one side wall to the other side wall are arranged instead of the photoelectric sensors arranged in the car. In this embodiment, motion sensors 38a to 38d are arranged on the right side wall, and motion sensors 38e to 38g are arranged on the left side wall. These motion sensors 38a to 38g do not require a light receiving element, and detect passengers by detecting infrared rays reflected by the passengers. It is preferable that the optical axes of the motion sensors 38a to 38g are appropriately inclined. By using such motion sensors 38a and 38g, it becomes possible to detect the entire interior of the car more randomly and more widely.

  As mentioned above, although this invention was demonstrated and mentioned with preferable embodiment, in the above-mentioned embodiment, although the operation of the elevator between the 1st floor and the 2nd floor was demonstrated as an example, about the stop floor of an elevator, for example, It is also possible to arbitrarily specify the first floor and the third floor, the second floor and the first floor, the second floor and the fifth floor, and operate between the designated floors.
