Abstract

Conventional elevator control systems have the function of stopping an elevator at a floor upon detecting an infant. However, even when the infant boards an elevator alone, the elevator starts the door closing operation and moves to the next destination floor. Thus, there is a problem in that the guardian of the infant is left at the elevator hall and cannot board the elevator with the infant. This elevator control system is characterized by determining whether or not a user who enters a car is a person to be guarded and using the degree or proximity between the person to be guarded and another user to determine whether or not the other user is a guardian.

Embodiment 1.
The overall configuration of an elevator according to Embodiment 1 of the present invention will be described with reference to FIG. The elevator includes an elevator control panel 11, a door control device 12, a hoisting machine 13, a main rope 14, a control cable 15, a counterweight 16, a car 17, a car door 18, a luminaire 8, and a determination device 2.

One end of the main rope 14 is connected to the upper end of the car 17. A counterweight 16 is connected to the other end of the main rope 14. The hoisting machine 13 is installed in an intermediate portion of the main rope 14 so that the car 17 and the counterweight 16 are moved up and down in opposite directions.
The door control device 12 opens and closes the door 18 of the car by using a door open / close signal sent from the elevator control panel 11 through the control cable 15 as an input signal.

The car 17 is provided with a determination device 2, a user detection means 5, a shadow detection means 6, a photoelectric device 7, a lighting device 8, and a door control device 12 for opening and closing a car door 18. Although the determination device 2 is illustrated as being installed in the car 17, the determination device 2 may be installed anywhere as long as the elevator control panel 11 can receive a signal from the determination device 2. For example, the determination device 2 may be provided inside the control panel 11.

The detailed configuration of the elevator control system according to the first embodiment will be described with reference to FIG. FIG. 2 is a functional block diagram of the elevator control system 1 according to the first embodiment.
The elevator control system 1 of the present invention includes a determination device 2, a user detection means 5, and a shadow detection means 6. The determination device 2 includes a parent determination unit 3 and a user determination unit 4. The parent determination unit 3 and the user determination unit 4 may be realized by hardware or software. Further, in the first embodiment, the parent determination unit 3 and the user determination unit 4 are included in the determination device 2, but may be included in the control panel 11.

The user detection means 5 is installed in the door 18 of the car and detects the user who gets into the car 17 from the landing. The user detection means 5 can also be used as a detection sensor that detects the user getting off from the inside of the car 17 to the hall and turns over the door. For example, the user detection means 5 uses the photoelectric device 7 installed near the doorway of the car door 18.

The user detecting means 5 is such that a plurality of photoelectric devices 7 are installed in the car door 18 at the same height from the floor surface. Depending on the order detected by the photoelectric device 7, it is possible to determine whether the user gets down from the inside of the car 17 to the hall or gets into the car 17 from the hall. For example, when a plurality of photoelectric devices 7 installed at the same height from the floor perform a detection operation in order from the inside of the car 17 to the outside, it is determined that the user is in a state of getting down from the inside of the car 17 to the hall. To do. On the other hand, when a plurality of photoelectric devices 7 installed at the same height from the floor perform detection operations in order from the outside to the inside of the car 17 near the hall, the user gets into the car 17 from the hall. Judge as a state.

∙ Install at least one photoelectric device 7 on the upper side and one on the lower side of the reference value for judging users. Further, a plurality of light projectors 7a and light receivers 7b for constituting the photoelectric device 7 may be installed at both ends of the entrance and exit of the car 17 so as to be horizontal with the floor surface inside the car 17. It should be noted that the light projector and the light receiver may be those that use the light projecting element and the light receiving element of the optical system to perform non-contact detection. The signal detected by the user detection means 5 using a sensor such as the photoelectric device 7 is transmitted to the user determination unit 4 described later.

The shadow detection means 6 includes a photosensitive element (not shown) laid on the floor inside the car 17. With respect to the light from the luminaire 8 inside the car 17 serving as a light source, a shadow detected by a photosensitive element installed on the floor inside the car 17 is acquired. The shadow is represented by an achromatic color that is a mixture of white and black, in addition to the two colors of white and black. The shadow detection unit 6 detects the shadow projected by the user and transmits the shadow image to the guardian determination unit 3 described later.

The determination method of the user determination unit 4 of the present invention will be described with reference to FIG. The user determination unit 4 uses the detection signal from the user detection means 5 to determine whether or not the height of the user who gets into the car 17 from the hall is less than or equal to a predetermined value, and the elevator user Determine if you are an infant. Here, when an elevator is used, a protected person who needs to move while watching over is defined as an infant so as not to be caught in the door or injured by opening and closing the door of the car 17.

The height of the standard value of the sensor that detects the user installed at the entrance of the car 17 is 1000 mm. The user determination unit 4 determines whether or not the height of the user who gets into the car 17 from the hall is 1000 mm or less. When the height is 1000 mm or less, the user determination unit 4 outputs a signal "I am an infant", and otherwise outputs a signal "I am not an infant".

The standard value for judging users is 1000 mm from the floor, and multiple sensors installed at the doorways of the car 17 to detect users are installed. It is assumed that an infant and a guardian are waiting at the elevator hall, and that two people get in after the car 17 arrives. The height of the guardian is 1500 mm, and the height of the infant is 900 mm.

When an infant and a guardian are on board the car 17, if the guardian is a guardian, the user detection means 5 installed 1000 mm or more above the floor detects an object. On the other hand, in the case of an infant, the user detecting means 5 installed less than 1000 mm below the floor detects an object. Based on the object detection signal from the user detection means 5, the user determination unit 4 determines that the parent is “not an infant” because the height is higher than the determination reference value. On the other hand, the user determination unit 4 determines that the infant is “infant” because the height is lower than the determination reference value. In the above example, the reference value is set to 1000 mm, but the present invention is not limited to this, and any reference value capable of determining whether or not the child is an infant may be used. Further, these reference values may be changeable by the user or the like.

The user determination unit 4 determines whether or not the child is an "infant" based on the signal from the user detection unit 5. However, the user determination unit 4 only needs to be able to detect the "infant". .. For example, in machine learning of AI (artificial intelligence), learning such as "adult", "child", and "infant" is performed from a human face image. An image of the face of the user inside the car 17 is collected from the camera 19 inside the car 17. The user determination unit 4 may determine whether or not the user inside the car 17 is an “infant” by using the signal obtained by the AI (artificial intelligence) face recognition technology. ..

The guardian determination unit 3 has a function of recording the shadow information from the shadow detection means 6 and a function of determining the degree of proximity between the infant inside the car 17 and the guardian. Here, the degree of proximity indicates the degree of proximity between the infant and the guardian, and it is defined that the distance between the infant and the guardian increases as the degree of proximity increases.

Next, a detailed configuration of the guardian determination unit 3 will be described with reference to FIG. FIG. 4 is a functional block diagram of the guardian determination unit 3.
The guardian determination unit 3 includes an image signal input interface unit 3a, a shadow image storage unit 3b, a difference processing unit 3c, an adjacent distance calculation unit 3d, a determination processing unit 3e, and an output interface unit 3f. The output interface unit 3f of FIG. 4 has an output interface function of the notification means 9 described later.

The image signal input interface unit 3a performs a process of taking the image of the shadow from the shadow detection unit 6 into the guardian determination unit 3.
The shaded image storage unit 3b is an image storage unit that stores the image captured by the image signal input interface unit 3a.
The difference processing unit 3c detects the difference between the images stored in the shadow image storage unit 3b. The image difference is defined as the image difference obtained by comparing the images inside the car 17 before and after the car door 18 is opened. The image difference detection process will be described with reference to an operation flowchart described later.
The adjacent distance calculation unit 3d calculates the distance between the plurality of shadows from the difference image processed by the difference processing unit 3c.
The determination processing unit 3e determines whether the distance between the plurality of shadows calculated by the adjacent distance calculation unit 3d is longer than the preset distance.

The output interface unit 3f is an interface unit that outputs the result of the determination made by the determination processing unit 3e to the outside. The signal to be output is a door opening / closing permission signal to the elevator control panel 11, a notification command to the notification means 9 described later, or the like.

A method for measuring the degree of proximity between an infant and a guardian from the shadows collected by the shadow detection means 6 will be described with reference to FIG. FIG. 5 is a diagram showing a method of measuring the approaching state by the shadow of the user in the car, which is detected by the shadow detecting means 6. The method of measuring the degree of approach is to measure the distance between the shadow and the tip of the shadow by the shadow detected by the shadow detecting means 6, or to calculate the center of each shadow and measure the distance to the center of each shadow. There is a way. The method of measuring the distance from the center of each shadow is effective when the infant and guardian are holding hands and the tip of the shadow cannot be measured.

A method for the guardian determination unit 3 to determine a guardian will be described with reference to FIG.
The guardian determination unit 3 determines whether or not the passenger inside the car 17 is a guardian based on the degree of proximity obtained by the shadow. For example, when the degree of approach is less than 500 mm, the passenger inside the car 17 is determined to be a “guardian”. On the other hand, when the degree of approach is 500 mm or more, the passenger inside the car 17 is determined to be a “stranger”.

The guardian determination unit 3 according to the present embodiment calculates the degree of approach using the shadows sampled by the shadow detection unit 6, but the invention is not limited to this, and any unit that can detect the degree of approach may be used. For example, the guardian determination unit 3 may calculate the degree of proximity by using an image acquired by the camera 19 installed inside the car 17 instead of the shadow detection unit 6.

The guardian determination unit 3 may use a laser rangefinder that detects the shape of an object instead of the shadow detection unit 6. The laser rangefinder includes a laser emitting device and a laser detecting device that detects a laser. For example, a laser range finder irradiates a laser beam from a laser emission device in a pulse shape, and detects a laser beam reflected by an object and returned by a laser detection device. The laser range finder measures the distance from the laser range finder to the object by using the time taken for the laser beam to be reflected and returned to the object after being emitted. The laser rangefinder uses this distance to measure the distance between the objects.

The guardian determination unit 3 notifies the control unit of the elevator control panel 11 whether the door can be opened or closed based on the result of the determination based on the degree of approach. The elevator control panel 11 outputs a door opening / closing command to the door control device 12, and the door control device 12 opens / closes the car door 18.

Next, the operation of the elevator control system 1 according to the first embodiment will be described with reference to FIG. FIG. 7 is an operation flowchart of the elevator control system 1 according to the first embodiment.

In step S1, before the elevator car 17 arrives at the destination floor and the door starts to open, the shadow detection unit 6 acquires the shadow inside the car 17 and determines the acquired shadow (shadow A in FIG. 8) as a guardian. Part 3 records. The parental determination unit 3 may perform the image averaging process after reading the shadows sampled by the shadow detection unit 6 a plurality of times. Even if the user inside the car 17 moves a little, the difference processing of the images is affected. Therefore, the averaging processing of the images improves the detection accuracy when the difference of the images is extracted.

In step S2, the car door 18 is fully opened, and the process proceeds to step S3.

In step S3, the user determination unit 4 detects a user who enters the car 17 from the hall based on the detection signal from the user detection means 5. Further, the user determination unit 4 determines whether or not the user is an infant based on the height of the user who enters the car 17 from the hall. If the user is an infant according to the determination result of the user determination unit 4 in step S3, the process proceeds to step S4 (YES in step S3).

In step S4, the shadow detection means 6 again acquires the shadow inside the car 17 (shadow B in FIG. 8) and causes the parent determination unit 3 to record this shadow.

In step S5, the guardian determination unit 3 detects the difference between the shadow (shadow A in FIG. 8) acquired in step S1 and the shadow (shadow B in FIG. 8) acquired in step S4. That is, the guardian determination unit 3 detects the difference between the shadows taken before and after the car door 18 opens when the car 17 arrives at the destination floor. In the process of detecting the difference, common shadows in the shadow A and the shadow B are removed, and a portion of the shadow B that does not exist in the shadow A is extracted (difference between the shadow A and the shadow B in FIG. 8).

In step S6, the guardian determination unit 3 calculates the degree of proximity between the infant and the guardian.

In step S7, the degree of proximity between the infant and the guardian is determined based on the degree of proximity calculated in step S6. If the degree of approach is larger than the reference value, the process proceeds to step S8 (YES in step S7). On the other hand, if the degree of approach is not greater than the reference value, it is determined that the infant and the guardian are approaching, and the process proceeds to step S11 (NO in step S7).

In step S8, it is determined that the infant inside the car 17 is not with the guardian, and the door is kept open.

In step S10, the door open duration time is determined after determining that the user is not an infant based on the determination result of the user determination unit 4 in step S3. After continuing the door open state for a certain period of time, the process proceeds to step S11 (YES in step S10). In step S10, when the door open duration time has not reached the certain time, the process proceeds to step S3 again (NO in step S10).

In step S11, a door closing permission signal is transmitted to the control panel 11, and the control panel 11 issues a door closing command to the door control device 12 to completely close the door, and then the user's next destination floor. Move the elevator car 17 to the elevator.

As described above, in the elevator control system 1 according to the present embodiment, when the infant entering the inside of the car 17 from the elevator hall is detected, the infant and the guardian can determine the proximity between the infant and the guardian. Since the elevator door opening / closing operation is performed after it is detected that the passenger is in the vehicle, it has an effect of solving the problem that the infant guardian is left in the elevator hall and cannot get on the vehicle together.

Embodiment 2.
The entire configuration of the elevator according to the second embodiment of the present invention will be described with reference to FIG. In the description of FIG. 9, parts corresponding to the overall configuration of the elevator according to the first embodiment are given the same reference numerals as those in FIG. 1, and description thereof will be omitted.

After the user determination unit 4 determines that the infant is a baby whose height is less than or equal to a predetermined value, the notification unit 9 determines by the guardian determination unit 3 the degree of proximity between the infant and the guardian, and the infant and the guardian are not close to each other. In this case, a notification is given to encourage the infants and their parents to approach each other. Further, when the proximity of the infant and the guardian is promoted but the degree of the proximity does not decrease, the notification means 9 notifies the infant of the announcement to get out of the car 17.

A functional block diagram of the elevator control system 1 according to the second embodiment of the present invention will be described with reference to FIG. In FIG. 10, the same symbols as those in FIG. 2 indicate the same or corresponding portions.

The guardian determination unit 3 has a function of recording the shadow information from the shadow detection means 6 described in the first embodiment and a function of determining the degree of proximity indicating the approaching state between the infant inside the car 17 and the guardian. Further, it has a function of issuing a notification output command to the notification means 9.

After the user determination unit 4 determines that the child is a child whose height is less than or equal to a predetermined value, the parent determination unit 3 determines the degree of proximity between the infant and the parent. As a result, when the infant and the guardian are not close to each other, the notification means 9 in FIG. 10 gives a notice to prompt the infant and the guardian to approach each other. Further, when the notification means 9 promotes the approach between the infant and the guardian, if the degree of approach between the infant and the guardian does not decrease, the notification means 9 notifies the infant of the announcement to get out of the car 17.

Next, the operation of the elevator control system 1 according to the second embodiment will be described with reference to FIG. FIG. 11 is an operation flowchart of the elevator control system 1 according to the second embodiment. In the description of FIG. 11, steps corresponding to the operation of the elevator control system 1 according to the first embodiment are designated by the same reference numerals as those in FIG. 7, and description thereof will be omitted.

In step S3, the user determination unit 4 detects a user who enters the car 17 from the hall based on the detection signal from the user detection unit 5. Further, the user determination unit 4 determines whether the user is an infant from the height of the user who enters the car 17 from the hall. If the user is an infant according to the determination result of the user determination unit 4 in step S3, the process proceeds to step S20 (YES in step S3).

In step S20, the notification means 9 notifies an announcement that prompts the infant and the guardian to approach each other, and then proceeds to step S4.

In step S8, the guardian determination unit 3 determines that the infant inside the car 17 is not with the guardian and issues a command to the elevator control panel 11 to continue the door open state. Then, the process proceeds to step S21.

In step S21, the guardian determination unit 3 confirms the number of times the notifying unit 9 notifies the infant and the guardian to approach each other, and when the notification is repeated more than the reference number of times, the process proceeds to step S22. (YES in step S21). On the other hand, when the number of notifications is less than the reference value, the process proceeds to step S4 (NO in step S21).

In step S22, the child inside the car 17 is informed to urge the car 17 to get off the platform.

The movements of the infant and the guardian before and after the notification by the notification means 9 of the present invention will be described with reference to FIG.
When the signal output from the user determination unit 4 is received as "infant", the notifying means 9 notifies the infant inside the car 17 and the guardian to approach each other. For example, the guardian should approach the child. "The guardian should hold hands with the child." In the specific example shown in FIG. 12, it is assumed that the guardian approaches the infant up to a distance of 400 mm according to the notification from the notification means 9.

If the passenger inside the car 17 is determined to be a "guardian" based on the determination result of the guardian determination unit 3, the door closing operation is started, and the elevator control system 1 is registered as the destination floor to the next destination floor. Start moving to. In addition, when the passenger inside the car 17 is determined to be a “stranger” based on the determination result of the guardian determination unit 3, the door opening operation is continued, and thereafter, the notification for approaching is continued for the number of times of the reference value. In this case, the child inside the car 17 is informed to urge the passenger to get off. In addition, although the notification that prompts the infant inside the car 17 to get off is performed on the basis of the number of times of notification, it may be used for the determination to notify the duration of the door opening. After the door 18 of the car has been kept open for a certain period of time or longer, the infant inside the car 17 may be informed to unload the car.

Further, in the user determination unit 4 and the parent determination unit 3, the determination reference value is changed to change the target from "infant" to "pet" of animal. For example, the reference value determined by the user determination unit 4 is lowered to a height of 100 mm. If the user determination unit 4 determines that the pet is a "pet", the notification unit 9 changes the notification to "Hold your pet."

For example, the reference value determined by the guardian determination unit 3 is 0 mm. If a pet with a lead gets into the car 17 from the hall and the door is closed and the elevator runs while the user is left in the hall, it becomes a dangerous state for the user of the elevator. When the user holds the pet and uses the elevator, the elevator can be used without anxiety.

As described above, in the elevator control system 1 according to the second embodiment, the car door 18 does not close when the proximity between the infant and the guardian is large (the infant and the guardian are separated). Therefore, the user inside the car 17 does not understand the reason why the car door 18 is not closed. The notification means 9 announces that the infant and the guardian are approaching each other, and the guardian determination unit determines the degree of approach again, so that the infant and the guardian can get on the elevator together. In addition, when one infant gets in the vehicle, the notification means 9 announces to the infant that the child 17 should leave the car 17, so that the guardian of the infant is left in the elevator hall, and it is not possible to get along with it. Have.

Embodiment 3.
The overall configuration of the elevator according to Embodiment 3 of the present invention is the same as that of FIGS. 1, 2, 9, and 10.
In the first and second embodiments, the user detecting means 5 is the user detecting means using the transmissive photoelectric device 7. However, it may be possible that an infant and a guardian line up and pass through the entrance / exit of the car 17. Therefore, in the third embodiment, the user determination unit 4 and the user detection means 5 will be described below.

In FIG. 3, the user detecting means 5 was a transmissive sensor in which the projector 7 a and the receiver 7 b of the photoelectric device 7 were arranged in pairs at both ends of the entrance and exit of the car 17. The user detecting means 5 of the third embodiment uses a reflective sensor instead of the transmissive sensor. Here, the reflection type sensor is a detector that outputs a detection signal from the sensor to detect a user who gets into the car 17 and detects a distance from the detection signal reflected by the user. Define. Further, the detection signal used for the reflection type sensor may be anything other than light or sound, as long as it is reflected by an object. The light projecting element and the light receiving element of the reflective sensor may be integrated elements. As a sensor for detecting the height of the user, a reflection type sensor such as an ultrasonic wave or a millimeter wave may be used in addition to the optical sensor.

The user determination unit 4 may include a sensor for detecting the capacitance near the doorway of the car 17 and a sensor for detecting the mass of an object as a sensor for improving the detection accuracy of the infant. The sensor for detecting the capacitance detects the size of the object based on the magnitude of the capacitance generated between the entrance of the car 17 and the object. A sensor that detects the mass of an object uses a piezoelectric sensor to detect the mass of the object.

Since the elevator control system 1 according to the third embodiment uses the sensor of the reflection type 4 for the user detecting means 5, the case where the infant and the guardian enter the car 17 in a lined state. However, it becomes possible to detect an infant. When an infant entering the car 17 from the elevator hall is detected, it is detected that the infant and the guardian are in the car 17 due to the proximity of the infant and the guardian. Therefore, there is an effect of solving the problem that the guardian of the infant is left in the elevator hall and cannot ride together.
