Embodiment 1 FIG.
1 is a block diagram showing an elevator apparatus according to Embodiment 1 of the present invention. In the figure, an elevator device includes a car 1 that moves up and down a hoistway, a weighing device 2 that measures the total weight of objects in the car 1, a landing button 3 provided at each landing on each floor, and a car doorway (elevator). A photoelectric device 4 for detecting an object passing through the doorway and an elevator control device 5 for controlling the raising and lowering of the car 1 are provided. The photoelectric device 4 is not limited to the car doorway, and may be provided at a landing doorway (elevator doorway). When the photoelectric device 4 detects an object passing through the car doorway, the car door that opens and closes the car doorway is restricted from moving in the door closing direction.

  FIG. 2 is a block diagram showing the photoelectric device 4 of FIG. In the figure, the photoelectric device 4 has a plurality of photoelectric elements 41 provided on both outer sides in the width direction of the car doorway. The plurality of photoelectric elements 41 are arranged side by side in the height direction. The photoelectric element 41 includes a light projecting unit that emits light and a light receiving unit that receives light emitted from the light projecting unit. The photoelectric device 4 creates image information corresponding to the shape of the object crossing the photoelectric device 4 based on whether or not the light receiving unit has received the light emitted from the light projecting unit. In other words, the photoelectric device 4 creates image information corresponding to the shape of the object passing through the car doorway. The image information created by the photoelectric device 4 is image information corresponding to the shape of the object when the object is viewed in the width direction of the car doorway.

  FIG. 3 is a block diagram showing the elevator control device 5 of FIG. The elevator control device 5 acquires image information from the photoelectric device 4, acquires an object size estimation unit 51 that estimates an object size and an object type c, and acquires a measurement result of the scale device 2 from the scale device 2. An object occupancy area calculation unit 53 that calculates an object occupancy area indicating an area that the object occupies in the car 1 by using the estimation result of the object size estimation unit 51 and the boarding / alighting determination unit 52 that determines whether the object is getting in and out of the car 1 And have. In this example, the object size estimation unit 51 estimates the object type c. However, the object type c is not limited to the object size estimation unit 51, and may be performed by the photoelectric device 4, for example. The boarding / alighting determination unit 52 outputs boarding / alighting information indicating the boarding of the object on the car 1 or the boarding / alighting from the car 1 as a judgment result.

  In addition, the elevator control device 5 uses the object occupation area calculated by the object occupation area calculation unit 53 and the boarding / alighting information of the object determined by the boarding / alighting determination unit 52 to indicate a boarding area that can be boarded in the car 1. A boarding area calculation unit 54 that calculates a possible area, a fullness determination unit 55 that determines whether or not the inside of the car 1 is full using the boarding area calculated by the boarding area calculation unit 54, and a hall When the button 3 is operated, the control device main body 56 performs the hall call registration to the landing floor where the hall button 3 is operated based on the determination result of the fullness determination unit 55.

  FIG. 4 is a diagram showing image information acquired from the photoelectric device 4 by the object size estimation unit 51 of FIG. The object size estimation unit 51 uses the image information acquired from the photoelectric device 4 to calculate the dimension h in the height direction of the object, and estimates the dimension d in the depth direction of the object. In addition, the object size estimation unit 51 estimates the object type c using the image information acquired from the photoelectric device 4. Examples of the object type c include a person, a wheelchair, and a bicycle. In addition, the person of the type c of the object may include a person who is tall and a person who is short. In this example, the depth direction is the direction of movement of the object when the object passes through the car doorway, and is the direction of arrow A in FIG.

  The dimension h in the height direction of the object corresponds to the height of the photoelectric element 41 at the highest position among the plurality of photoelectric elements 41 that have not received the light emitted from the light projecting unit. Therefore, the object dimension estimation unit 51 calculates the height of the photoelectric element 41 that is shielded from light at the highest position among the plurality of photoelectric elements 41 as the dimension h in the height direction of the object.

  The dimension d in the depth direction of the object is a value obtained by multiplying the moving speed of the object by the time when the light receiving unit does not receive the light emitted from the light projecting unit. Therefore, the object size estimation unit 51 estimates a value obtained by multiplying the moving speed of the object by the time when the photoelectric element 41 is shielded from light as the dimension d in the depth direction of the object. In this example, since the moving speed of the object cannot be calculated from the image information, a preset value is used as the moving speed of the object.

As for the dimension d in the depth direction of the object, the value d ₀ obtained by multiplying the moving speed of the object by the time when the photoelectric element 41 is shielded from light and the type c of the object are used. It may be estimated as follows.

d = D (c, d ₀ ) (1)

In the above equation (1), when the type c of the object is a person, the dimension in the depth direction of the person is generally about 30 cm to 40 cm. The scale is adjusted, and a value d ₀ estimated from the adjusted image information is set as a dimension d in the depth direction of the object.

In the above formula (1), when the object type c is a wheelchair or a bicycle, the wheel portion is circular, so that the wheel portion extracted from the image information is circular. The scale of the information is adjusted, and a value d ₀ calculated from the adjusted image information is set as a dimension d in the depth direction of the object. At this time, the radius in the height direction in the wheel portion is a reference.

  For estimating the dimension d in the depth direction of the object, a table set in advance so as to satisfy the above equation (1) may be used.

  Further, the object size estimation unit 51 estimates the dimension w in the width direction of the object using the information on the type c of the object, the dimension h in the height direction of the object, and the dimension d in the depth direction of the object. The image information of the object does not include information on the dimension w in the width direction of the object. However, since the dimension w in the width direction of the object is correlated with the type c of the object, the dimension h in the height direction of the object, and the dimension d in the depth direction of the object, the object dimension estimation unit 51 includes A conversion function or a discrete conversion table is prepared by substituting the type c, the dimension h in the height direction of the object, and the dimension d in the depth direction of the object into the following equation (2). In this example, the width direction is the frontage direction of the car entrance.

    w = F (c, h, d) (2)

  In the above formula (2), if the object type c is a person and the height dimension h is relatively small, the object type is likely to be a small person. The dimension w in the width direction of the object is reduced. On the other hand, when the type c of the object is a person and the height dimension h is relatively large, the object is likely to be a large person, so the dimension w in the width direction of the object is growing. Note that the dimension w in the width direction of the object may be estimated from the measurement result of the scale device 2 further considering weight information indicating the weight of the object.

  The boarding / alighting determination unit 52 acquires the measurement result of the scale device 2. The boarding / alighting determination unit 52 determines whether the object has got on the car 1 or whether the object has got off the car 1 based on the measurement result of the scale device 2 and outputs boarding / alighting information.

  The object occupation area calculation unit 53 obtains the dimension d in the depth direction of the object and the dimension w in the width direction of the object from the object dimension estimation unit 51.

When the object occupation area calculation unit 53 acquires the dimension d in the depth direction of the object and the dimension w in the width direction of the object, the object occupation area S, which is the area that the object occupies in the car 1, according to the following equation (3). ₁ is calculated.

S ₁ = w × d (3)

Object occupation area S ₁ is calculated from the object in the depth direction of the dimension d and the object width dimension w of dimension d of the object in the depth direction is varied by the object moving speed of the width direction of the object dimension w , if so vary by an object in the depth dimension d, the object occupies an area S ₁ which is calculated by formula (3) is extremely smaller than that extremely large or actual area than the actual area Can be considered. Therefore, the object occupation area calculation unit 53 calculates the correction coefficient α using the following equation (4).

α = G (S ₁ / S (c)) (4)

  In the above equation (4), S (c) is the standard object occupation area for the object type c, and is a standard area preset for each object type c. Moreover, in said Formula (4), G is a conversion function, for example, is a function like the following formula | equation (5).

α = 0.3 × (S ₁ /S(c)−1.0)+1.0 (5)

FIG. 5 is a graph showing the correction coefficient. As shown in the figure, the correction coefficient α is about 0.7 even if the calculated object occupation area S ₁ is small, and is not likely to be an abnormal value even if the calculated object occupation area S ₁ is large. The conversion function G may take a function as shown in FIG. 6, for example. In this case, an upper limit value and a lower limit value are set for the correction coefficient α.

Object occupying area calculation unit 53, by substituting the calculated object occupation area S ₁ and the correction coefficient α in Equation (6) below, to calculate the corrected object occupation area S _2. That is, the object occupation area is corrected using the correction coefficient α.

S ₂ = α × S (c) (6)

Further, the object occupation area calculation unit 53 uses the boarding / alighting information (rε {−1, +1}) acquired from the boarding / alighting determination unit 52 and the corrected object occupation area S ₂ to occupy the object. to calculate the area _{S 3.} Specifically, the object occupation area calculation unit 53 uses the following expression (7) for the boarding / alighting information (rε {−1, +1}) acquired from the boarding / alighting determination unit 52 and the corrected object occupation area S _2. by substituting in), and calculates the object area occupied S ₃ of the object that is getting on and off.

S ₃ = r × S ₂ (7)

Ride possible area calculation unit 54 uses the object area occupied S ₃ of the object occupied area calculating unit 53 is calculated, the current, and calculates the total area O _s occupied by the object _(t). If the current step is t, the total area O _s (t) occupied by the object is calculated by using the following equation (8).

O _s (t) = O _s (t−1) + S ₃ (8)

  Step t increases by +1 every time an object gets on and off.

Further, the boardable area calculation unit 54 calculates the boardable area V _s (t) by substituting the total area O _s (t) occupied by the object into the following equation (9).

V _s (t) = C _s −O _s (t) (9)

In the above equation (9), C _s is the car area and is a value set in advance depending on the size of the car 1.

  The fullness determination unit 55 includes a table (table A) that records the number of times of boarding for each type c of objects in a predetermined period and a table (table B) that records the number of objects boarded during one stop. Yes. The fullness determination unit 55 periodically updates the table A and the table B.

  FIG. 7 shows a table (table A) that records the number of times of boarding for each object type c in a predetermined period, and FIG. 8 shows a table (table B) that records the number of objects boarded during one stop. FIG.

  The fullness determination unit 55 uses the table A and the following equation (10) to estimate the standard object occupation area expected value indicating the standard object occupation area S that is occupied by one boarding of the object car 1. E (S) is calculated.

In addition, the fullness determination unit 55 substitutes the calculated standard object occupation area expected value E (S) into the following equation (11), thereby indicating the expected number of boardable objects that indicates the expected number of objects that can be boarded. E (V _h ) is calculated.

E (V _h ) = V _s (t) / E (S) (11)

  Further, the fullness determination unit 55 uses the table B and the following expression (12), and the expected number of boarded objects E indicating the expected number of objects to be boarded during one stop at the platform of the car 1. (H) is calculated.

  Note that the standard object occupation area expected value E (S) is a value specified in advance in a state where sufficient data is not accumulated in the tables A and B because the number of times of boarding is small as in the initial operation stage. Alternatively, the expected number of boarded objects E (H) may be a value designated in advance. Further, a plurality of tables A and B may be provided corresponding to each season, every month, or every time zone, or a plurality of tables A and B may be provided corresponding to each floor.

In addition, the fullness determination unit 55 compares the expected number of boardable objects E (V _h ) with the expected number of boarded objects E (H). When the expected number of boarded objects E (H) is larger than the expected number of boardable objects E (Vh) (E (Vh) <E (H)), the fullness determination unit 55 indicates that the car 1 is full. Judge that there is. On the other hand, when the expected number of boarded objects E (H) is smaller than the expected number of boardable objects E (Vh) (E (Vh)> E (H)), the fullness determination unit 55 determines that the inside of the car 1 is Judge that it is not full.

  When the landing button 3 is operated and the fullness determination unit 55 determines that the car 1 is not full, the control device main body 56 performs landing call registration to the landing floor where the landing button 3 is operated. . On the other hand, when the hall button 3 is operated and the fullness determination unit 55 determines that the car 1 is full, the control device main body 56 is landing on the landing floor where the hall button 3 is operated. Do not call registration.

  Next, the operation of the elevator control device 5 will be described. FIG. 9 is a flowchart showing the operation of the elevator control device 5 of FIG. First, the object size estimation unit 51 acquires image information from the photoelectric device 4 (step S101).

  After that, the object size estimation unit 51 estimates the type c of the object using the image information (Step S102), calculates the height h of the object in the height direction (Step S103), and the size d of the object in the depth direction. Is estimated (step S104).

  Thereafter, the object size estimation unit 51 estimates the dimension w in the width direction of the object using the information on the type c of the object, the dimension h in the height direction of the object, and the dimension d in the depth direction of the object (step S105).

Thereafter, the object occupied area calculating unit 53, using the object in the depth direction of the dimension d and the width dimension w, and calculates the object occupying area S ₂ (step S106).

  Thereafter, the boarding / alighting determination unit 52 acquires the measurement result of the scale device 2 and determines whether the object has got on the car 1 or whether the object has got off the car 1 (step S107).

Thereafter, the boarding area calculation unit 54 calculates the boarding area V _s (t) using the object occupation area S ₃ of the boarded / alighted object (step S108), and the fullness determination unit 55 sets the boarding area V _s. Using (t), it is determined whether or not the car 1 is full (step S109). Thus, the operation of the elevator control device 5 ends.

As described above, according to the elevator control device 5 according to the first embodiment of the present invention, the object is moved to the car using the image information corresponding to the shape of the object crossing the photoelectric device 4 provided at the elevator doorway. calculating an object occupying area S ₂ showing the area occupied by the 1, by using the object passenger information corresponding to the object area occupied S ₂ and the object occupying area S _2, showing a possible area ride in the car 1 Install the pressure sensor on the floor of the car 1 because the boardable area V _s (t) is calculated and it is determined whether the car 1 is full using the boardable area V _s (t). It can be determined whether the car 1 is full. As a result, the hall call registration of the car 1 having no boardable space can be prevented, and the configuration of the elevator apparatus can be simplified.

  Further, the object dimension estimation unit 51 estimates the dimension d in the depth direction of the object by using the image information and the information of the type c of the object estimated from the image information. It can be estimated more accurately.

  Further, the object size estimation unit 51 calculates the height h of the object from the image information, information on the type c of the object estimated from the image information, the dimension h in the height direction of the object, and the depth direction Since the dimension w in the width direction of the object is estimated using the dimension d, the dimension w in the width direction of the object can be estimated more accurately.

The object occupation area calculation unit 53 also sets a standard object occupation area S (c) set in advance in correspondence with the dimension d in the depth direction and the dimension w in the width direction of the object, and the object type c estimated from the image information. ) and using, so to calculate the object occupying area S _2, you are possible to estimate the object occupying area S ₂ more accurately.

Moreover, it packed determining unit 55, by using the standard object area occupied expectation E (S) and the rider seated area V _{s (t),} calculates the rider seated object number expected value E a (V _h), ride the object number When the expected value E (H) is larger than the expected number of objects E (V _h ), it is determined that the car 1 is full. Therefore, it is determined whether the car 1 is full. Can be done accurately.

Although in the above-mentioned first embodiment, by using the corrected object occupation area S _2, it has been described structure for calculating the object area occupied S ₃ of boarding the object, using the object area occupied S ₁ uncorrected Te may be configured to calculate the object area occupied S ₃ of the object that is getting on and off.

Further, in the first embodiment, the configuration in which the elevator control device 5 has the rideable area calculation unit 54 has been described, but the elevator control device 5 may have a configuration in which the rideable area calculation unit 54 is not provided. In this case, the fullness determination unit 55 determines whether or not the inside of the car 1 is full based only on the total occupied area of the object. That is, using only the total area O _s (t) obtained by the above equation (8), the fullness determination unit 55 determines whether the car 1 is full. In this case, the full capacity determination unit 55 determines that the interior of the car 1 is full when the total area O _s (t) exceeds a predetermined value (for example, a fixed value or a certain percentage of the car capacity). .

Embodiment 2. FIG.

In the first embodiment, the elevator control device 5 includes the rideable area calculation unit 54, whereas in the second embodiment, the elevator control device 5 uses the total object area instead of the rideable area calculation unit 54. A weight calculation unit 57 is included. The total object weight calculation unit 57 calculates the total weight W (t) of the object that has entered the car 1 using the following equation (13).

    W (t) = W (t-1) + W (13)

  In the above equation (13), W is the weight of the object that got on and off at step t, and is calculated using the following equation (14) when the type c of the object that got on and off is other than a person. In addition, when the object which got on and off is a person, the variation | change_quantity of the measurement result of the balance apparatus 2 is used as a weight of an object as it is.

In the above formula (14), W (c ₁ ) is a standard object weight indicating a standard weight when the object type c is a person, and is about 65 kg in this example. In the above equation (14), S (c ₁ ) is a standard object occupation area when the object type c is a person. The fullness determination based on the total weight of the object is set with a fullness weight reached when a person gets on the seat as a determination number. Therefore, the total object weight calculation unit 57 determines that the object type c is other than a person to, by using the above equation (14), to calculate the weight of the assumption that people object object occupation area S ₂ of which rides on the car 1 is occupying, the calculated weight of type c of non-human Used as the weight of the object. The fullness determination unit 55 determines whether the car 1 is full based on whether the total weight W (t) calculated by the total object weight calculation unit 57 reaches the full weight. Other configurations are the same as those in the first embodiment.

FIG. 11 is a flowchart showing the operation of the elevator control device 5 of FIG. Steps S201 to S207 are the same as steps S101 to S107 of the first embodiment. After the boarding / alighting determination unit 52 determines boarding / alighting of the object, the object total weight calculation unit 57, when the type c of the object is a person, the object that has boarded or unloaded the variation amount of the measurement result of the scale device 2 in the car 1 If the object type is other than a person, the standard object occupation area S (c ₁ ) and standard object weight W (c ₁ ) of the person, the object occupation area S _2, and the getting-on / off information are set. used, as the weight of the object person to the object occupying area S ₂ is landing weight calculated assuming occupied, calculates the total weight W of the object in the car 1 (t) (step S208) . The full capacity determination unit 55 determines whether the car 1 is full using the total weight of the objects in the car 1 calculated by the total object weight calculation unit 57 (step S209). Thus, the operation of the elevator control device 5 ends.

As described above, according to the elevator control device 5 according to the second embodiment of the present invention, when the object type c estimated from the image information is a person, the variation amount of the measurement result of the scale device 2 If the object type is other than a person, the standard object occupation area S (c ₁ ), standard object weight W (c ₁ ), and object occupation area S ₂ set in advance by using the boarding information, a weight of the object that passenger weight calculated on the assumption that people object occupation area S ₂ is occupied, then calculates the total weight W of the object (t), was calculated basket Since the total weight W (t) of the objects in 1 is used to determine whether or not the inside of the car 1 is full, the inside of the car 1 is full without installing a pressure sensor on the floor of the car 1. It can be determined whether or not. As a result, the hall call registration of the car 1 having no boardable space can be prevented, and the configuration of the elevator apparatus can be simplified.

While in this second embodiment, although people corrected object occupation area S ₂ has been described structure for calculating the weight of the object assuming occupied, the object occupies an area S ₁ that has not been corrected The configuration may be such that the weight of the object is calculated on the assumption that the person is occupying.
