Description

  The present invention relates to an elevator car dispatcher equipped with a load detector.

  In recent years, there has been proposed an elevator that measures the number of passengers in a car in consideration of the load of the elevator car and the floor area in the elevator car.

  Generally, a conventional elevator control device has a configuration as shown in FIGS.

  FIG. 8 is an explanatory view showing an overall outline of a car suitability state determination system in a conventional elevator control system, FIG. 9 is an explanatory view showing a cross section in the car, and FIG. 10 is an upper surface of the car showing the positional relationship of sensors. FIG. 11, FIG. 11 is a block diagram of one car shown in FIG. 8, FIG. 12 is a top view showing an object detected by each sensor, and FIG. 13 is a flowchart for determining the suitability state of the car. It is.

  As shown in FIG. 8, the system 10 determines whether or not the car can respond to the hall call, and is combined with a plurality of sensors 12 installed in each car 14 and each car. A plurality of sensor processing signal means 16 provided for receiving and processing each detection signal from each sensor 12 and communication with the sensor signal processing means 16 in order to control the car 14 in response to a hall call. And control means 18 for performing the above.

  Further, as shown in FIG. 9, each car 14 includes a plurality of sensors 12 provided in or close to the ceiling 20 of the car 14.

  Also, as shown in FIG. 10, each sensor 12 is arranged as an orthogonal array of rows and columns.

  Further, as shown in FIG. 11, each sensor 12 includes an infrared projector 22 and an infrared receiver 24. The infrared projector 22 of each sensor 12 is configured to project infrared rays, and each infrared receiver 24 is configured to receive reflected infrared rays. As a result, each sensor 12 is used as an on-type upon entering light that outputs an electrical signal when infrared energy is incident on the infrared light receiver 24.

  Here, as shown in FIG. 9, in one operation mode of the system 10, each infrared light receiver 24 is limited only to the reflected infrared light generated at a location separated from the floor 28 of the car 14 by a predetermined height dimension H or more. The threshold or sensitivity is adjusted in advance so that a signal is output in response. Thus, if there is no object having a predetermined height H or more in the car 14, the reflected light is not substantially incident on the infrared receiver 24, so that no voltage signal is output.

  Therefore, as shown in FIG. 11, the plurality of sensors 12 receive reflected light that is equal to or greater than the threshold value, and thereby output voltage signals to the sensor signal processing means 16, respectively. For example, the plurality of sensors 12 located in the hatched portion 38 in FIG. 12 take infrared reflected light having an intensity exceeding the threshold. Therefore, the number and arrangement relationship of these sensors 12 that output signals that receive strong reflected light that is equal to or greater than the threshold value indicate the area of the car 14 occupied by the object 36.

  Here, the flow of determining whether or not the car 14 is suitable for the hall call by the control means 18 will be described.

  As shown in FIG. 13, for example, a normal clock signal can be used to start from step 44.

  Next, in step 46, the output signal from each sensor 12 is read.

  In step 48, based on the state of each output signal read in step 46, infrared reflected light from the object 36 having a predetermined height H or more is received from each sensor 12, and a detection signal is output. Simply calculate the number of sensors. In this step 48, the ratio of the number of active sensors to the total number of sensors is obtained, and the available space in the cross section of the car 14 is calculated based on this operating ratio.

  Next, in step 49, the remaining load of the car 14 is determined. The initial value of the remaining load guarantees the total weight (maximum load) of passengers who can get on the car 14.

  In step 50, it is determined whether or not the current occupied area is smaller than the total area of the car 14.

  Next, in step 52, the vacant area of the car 14, which is the difference between the total area and the current occupied area, is compared with a predetermined value set in advance.

  If the current occupied area is equal to the total area of the car 14 in step 50, it is determined as "NO" and the process is terminated. In the step (not shown), the car 14 responds to the hall call. An inadequate signal indicating that it is not suitable is output.

  If the occupied area detected by the signal from each sensor 12 is smaller than the predetermined value, in step 54, it is indicated to the control means 18 that the car 14 is suitable for hall call response. Output a signal.

  If the remaining area is smaller than the predetermined value, step 52 determines "NO", and an unsuitable signal that this car 14 is unsuitable for hall call response is output in a step not shown.

In the elevator as described above, even when the car 14 arrives after calling for a hall call, there is not enough boarding space because an article such as an appliance is already mounted therein, and the problem that the user is frustrated is solved. Can do.
JP 7-277621 A (page 4-5, FIGS. 1 to 6)

  However, the above elevator control device has the following problems.

  Even if there is enough boarding space in the car, if there are more people getting into the car from the boarding than in the car boarding space, not all passengers on the boarding board can get into the car. For this reason, in order to get passengers on the landing, the car was dispatched to the landing many times, which was a wasteful operation of the car.

  Therefore, the present invention has been made in order to solve the above-mentioned conventional problems, and it is only possible to refer to the result of comparison between the passenger number detector provided at the landing and the car space detector provided in the car. The purpose of this service is to eliminate unnecessary car operation and improve elevator service.

  In order to achieve the above object, an elevator control device according to the present invention includes: a car load detection device that is provided on an elevator car floor and detects a load in the car, and is provided on the elevator car. The car number detecting device for detecting the number of people in the elevator and the elevator hall, where the call registration of the car is not registered, and the call registration of the hall is registered only in the same direction as the operation of the car If there is a passenger number detection device for detecting the number of people waiting to enter the car at the landing, the number of people detected by the car number detection device is compared with the number of people detected by the passenger number detection device. The number of persons detected by the hall number detection device by the number comparison means when the load detected by the car load detection device is smaller than a predetermined value Only when the number of people detected by the car number detecting device is smaller than the number of people detected by the car number detecting device, the car delivering means for delivering the car to the hall where the number of people is detected by the hall number detecting device is provided. .

  According to the elevator control device of the present invention, useless operation of a car can be eliminated and the service of the elevator can be improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  Embodiment 1 of the present invention will be described below with reference to FIGS.

  1 is a system configuration diagram of an elevator control apparatus according to a first embodiment of the present invention, FIG. 2 is a first flowchart of the elevator control apparatus according to the first embodiment of the present invention, and FIG. 3 is an embodiment of the present invention. 2 is a second flowchart of the elevator control apparatus according to FIG.

  First, the overall configuration of the elevator control apparatus according to the first embodiment of the present invention will be described with reference to FIG.

  As shown in FIG. 1, an elevator control device 56 of an elevator control panel 55 is installed in the machine room 51.

  Further, the elevator car 52 includes an elevator car number detecting device 63 for detecting a congestion state with respect to the floor area of the elevator car, an elevator car call input device 58 for inputting an elevator car call, and an elevator car load for detecting a load in the elevator. A detection device 57 and an elevator car display device 60 for notifying passengers in the elevator car of the elevator status and other information are provided.

  In addition, the hall 53 on each floor is notified of a hall number detector 64 for detecting the number of people waiting for boarding at the hall, a hall call input device 59 for calling the elevator to the hall, and the elevator status and other information to the hall passengers. A hall display device 61 is provided. In the embodiment, for example, the floor for the second floor is displayed.

  Further, the monitoring room 54 is provided with a monitoring panel display device 62.

  Next, the operation of the elevator control device 56 inside the elevator control panel 55 will be described with reference to FIGS.

  It is determined whether there is a car call on the Nth floor, which is an arbitrary floor, from the elevator car call input device 58 (ST1).

  If yes, there is a car call on the Nth floor, stop at the Nth floor (ST2).

  Then, the assignment of the elevator car 52 is completed (ST3).

  Here, the load is detected by the elevator car load detection device 57 in the car (ST4).

  If there is no N-th floor car call, it is determined whether the load signal from the elevator car load detector 57 is equal to or greater than a predetermined value (ST5).

  If the load signal of the elevator car load detection device 57 is greater than or equal to a predetermined value, it is considered that the car is full and the Nth floor passes (ST6).

  If the load signal of the elevator car load detecting device 57 is greater than or equal to a predetermined value, the car is not considered full, and the elevator car number detecting device 63 continuously detects the number of people in the car ( ST7).

Based on the number of people in this car, it is determined whether there is an empty space in the car (ST8).
If the elevator car number detection device 63 indicates that there is an empty space, the car is considered full and the Nth floor passes (ST6).

  If the elevator car number detecting device 63 determines that there is an empty space, the car is not considered full, and the Nth floor hall call input device 59 subsequently determines whether there is registration in both the vertical direction. (ST9).

  If the hall call input device 59 on the Nth floor is registered in both the up and down directions, since it is not possible to determine the allocation of people in the upper and lower directions on the Nth floor, it stops at the Nth floor for the time being (ST2).

  If the N-floor hall call input device 59 is registered in both the up and down directions, it is possible to determine the number of people going up and down on the N floor, and then the N-floor boarding direction call in the direction of the car travels. Judgment is made (ST10).

  If there is a hall call for the Nth floor traveling in the direction of the car, it passes through the Nth floor because there is a hall call for the Nth floor traveling in the opposite direction of the car or there is no call for the Nth floor. (ST6).

  If it is YES whether there is a hall call for the N-th floor in the direction of the car, the number of halls is detected by the hall number detector (ST11).

  Then, it is determined whether the number of passengers in the elevator car number detection device 63 minus the number of people in the elevator car number detection device 63 is larger than the number of waiting passengers in the Nth floor passenger number detection device 64 (ST12).

  If YES, the number of passengers waiting for passengers in the Nth floor hall is greater than the number of passengers waiting for boarding in the Nth floor hall passenger number detection device 64. All can ride, so stop at the Nth floor (ST2).

  If the number of passengers in the elevator car occupancy detection device 63 minus the number of passengers in the elevator car occupancy detection device 63 is greater than the number of passengers waiting in the N floor occupancy detection device 64, the passenger waiting in the N floor is No one can get on. Therefore, it is determined whether it is the terminal floor that has finished answering all calls in the car traveling direction other than the Nth floor (ST13).

  If it is NO which is the terminal floor that has finished responding to all calls in the car traveling direction other than the Nth floor, since the car traveling direction call is still registered, it passes through the Nth floor (ST6).

  If it is YES that the terminal floor has finished answering all calls in the car traveling direction other than the Nth floor, there is no call in the car traveling direction, and the number of passengers waiting on the boarding number detection device 64 on the Nth floor continues. It is determined whether there are more car rated passengers (ST14).

  If YES, whether the number of passengers in the car is larger than the number of passengers waiting for the passengers on the Nth floor, the number of passengers waiting on the Nth floor, all passengers waiting on the Nth floor can be on board. The response is given priority (ST15).

  If the number of passengers in the car is larger than the number of passengers waiting to be boarded on the N-th floor passenger number detection device 64, the traveling direction of the elevator car is reversed and the call in the opposite direction to the call on the Nth floor that has passed. Normal response to Subsequently, it is determined whether the response to the reverse call has been completed (ST16).

  If the answer to the reverse call has been completed, NO passes through the Nth floor in order to give priority to answering all reverse calls (ST6).

  If the answer to the call in the reverse direction has been completed, the rated number of passengers in the elevator car is larger than the total number of people with the number detector 64 on the middle floor until the next N-th floor call is answered. Is determined (ST17).

  If the answer is yes if the number of passengers in the elevator car is larger than the total number of passengers on the intermediate floor until the answering of the call on the Nth floor that has passed, a normal response is made and the Nth floor Stop (ST18).

  If it is NO that the rated number of passengers in the elevator car is larger than the total number of passengers on the middle floor until the answering of the call on the Nth floor passed, the Nth floor is given priority in response (NO) ST19).

Finally, the assignment of the elevator car 52 is completed (ST3).
According to the first embodiment of the present invention, the car can be dispatched by referring to the result of comparison between the boarding number detection device provided in the hall and the elevator car number detection device provided in the car. This can eliminate unnecessary car operation and improve elevator service.

  Hereinafter, Example 2 of the present invention will be described with reference to FIGS.

  4 is a system configuration diagram of an elevator control apparatus according to a second embodiment of the present invention, FIG. 5 is a first flowchart of the elevator control apparatus according to the second embodiment of the present invention, and FIG. 6 is an embodiment of the present invention. FIG. 7 is a third flowchart of the elevator control apparatus according to the second embodiment of the present invention.

  In the following embodiments, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  Referring to FIG. 4, the second embodiment of the present invention is an elevator system having a plurality of elevators.

  The elevator cars 52a, 52b, 52c of the elevators A, B, and C are an elevator car number detection device 63 that detects the congestion status with respect to the floor area of the elevator car, and an elevator car call that performs elevator car call input. An input device 58, an elevator car load detection device 57 for detecting the load in the elevator, and an elevator car display device 60 for notifying passengers in the elevator car of the elevator status and other information are provided.

  Further, in the elevator machine room 51, elevator control panels 55 of elevators A, B, and C are installed, and a group management control device 66 of a group management control panel 65 is also installed.

  And it is wired so that transmission is possible with the elevator control device 56 in the elevator control panel 55 of the elevator No. A, No. B and No. C. This makes it possible to control elevators A, B and C.

  The hall 53 includes a hall number detector 64 for detecting the number of people waiting for boarding at the hall, a hall call input device 59 for calling the elevator to the hall, and a hall display device 61 for notifying the passengers of the elevator status and other information. Is equipped.

  The monitoring room 54 is provided with a monitoring panel display device 62.

  Here, the operation of the elevator control device 56 inside the elevator control panel 55 will be described with reference to FIGS.

  First, it is determined whether there is a car call of the A-th car on the Nth floor, which is an arbitrary floor, from the elevator car call input device 58 (ST21).

  If YES, it is YES if there is a car call for the Nth floor A machine, and the A machine stops at the Nth floor in response to the car call (ST22).

  Then, the assignment of the elevator car 52 ends (ST23).

  If there is no car call for the car on the Nth floor, the load is detected by the elevator car load detector 57 of the A machine (ST24).

  Then, in order to know whether the car of No. A is full, it is determined whether the input value of the elevator car load detecting device 57 of No. A is greater than a predetermined value (ST25).

  If the input value of the elevator car load detection device 57 of No. A is equal to or greater than a predetermined value, the car of No. A is full and passes through the N floor (ST26).

  If the input value of the elevator car load detection device 57 of Unit A is NO or greater than the predetermined value, it is possible to get on the car of Unit A, so the number of passengers is detected by the elevator car number detection device 63 of Unit A. Detect (ST27).

  Then, it is determined whether there is an empty space in the elevator car number detection device 63 of Unit A (ST28).

  If NO in the elevator car number detection device 63 of Unit A, if there is an empty space, the Car of Unit A is full and therefore passes through the Nth floor (ST26).

  If there is a vacant space in the elevator car number detection device 63 of Unit A, it is possible to get in the car of Unit A, so the Nth floor hall call input device 59 continues to be registered in both the up and down directions. (ST29).

  If the hall call input device 59 on the Nth floor is registered in both the up and down directions, since the number of hall calls going up and down cannot be determined, Unit A responds to the call and N Stop on the floor (ST22).

  If the N floor hall call input device 59 is NO in both the up and down directions, the allocation of the number of hall calls going up and down can be determined. The number of passengers is detected (ST30).

  Then, it is determined whether there is a hall call in the direction of travel on the Nth floor in the direction of car travel of Unit A (ST31).

  If NO, there is a hall call in the direction of the Nth floor in the direction of car movement of Unit A, because there is a hall call in the Nth floor that is opposite to the direction of car travel, or no call for the Nth floor has occurred, Unit A passes through the Nth floor (ST26).

  If there is a call in the direction of travel on the Nth floor in the direction of travel of the car in Unit A, the elevator car of Unit A will start from the rated number of cars in Unit A rather than the number of passengers waiting for the passenger detection device 64 on the Nth floor. It is determined whether the number of people that can be ridden by the number detection device 63 is large (ST32).

  If the number of passengers obtained by subtracting the number of people that can be boarded in the elevator car number detection device 63 of the A elevator from the rated number of people in the A car than the number of people waiting for the boarding number detection device 64 on the N floor is YES, the N floor All passengers waiting on boarding can board the hall. Therefore, Unit A responds to the call and stops on the Nth floor (ST22).

  If NO is the number of passengers on the Nth floor, the number of passengers waiting for the passengers on the Nth floor is less than the rated number of cars in the Unit A minus the number of passengers in the elevator car number detection device 63 on the Nth floor, the Nth floor All passengers waiting at the landing are not allowed to board. Then, it is determined whether all units other than Unit A are operating in the opposite direction to Unit A (ST33).

  If all Units other than Unit A are operating in the opposite direction to Unit A, there is no unit operating in the same direction as Unit A, so Unit A will answer N. Stop on the floor (ST22).

  If all units except Unit A are operating in the opposite direction to Unit A, there is a unit other than Unit A in the same direction as Unit A (for example, Unit B). The elevator car load detector 57 detects the load (ST34).

  Then, it is determined whether or not the input value of the elevator car load detection device 57 of Unit B is a predetermined value or more (ST35).

  If the input value of the elevator car load detection device 57 of No. B is YES or higher than the predetermined value, the car of No. B is full and passes through the N floor (ST26).

  If the input value of the elevator car load detection device 57 of Unit B is NO or more than a predetermined value, it is possible to get on the car of B Unit, so the number of people in the elevator car number detection device 63 of Unit B continues. Detect (ST36).

  Then, it is determined whether there is an empty space in the elevator car number detection device 63 of Unit B (ST37).

  If there is NO in the elevator car number detection device 63 of Unit B that there is an empty space, the Car of Unit B is full and passes through the N floor (ST26).

  If there is a vacant space in the elevator car number detection device 63 of Unit B, the number of passengers waiting for the passenger number detection device 64 on the Nth floor is from the rated number of people in the B car to the elevator car number detection device 63. It is determined whether the number is greater than the number of possible people (ST38).

  If the number of passengers waiting on the Nth floor boarding number detection device 64 is larger than the number of passengers obtained by subtracting the number of passengers allowed on the elevator car number detection device 63 from the rated number of cars in Unit B, NO, Since all the passengers waiting for boarding can board Unit B, Unit A passes through the Nth floor, and Unit B stops at the Nth floor in response to the call (ST26).

  If the number of passengers waiting on the Nth floor boarding number detection device 64 is larger than the number of passengers obtained by subtracting the number of passengers that can be boarded in the elevator car number detection device 63 from the rated number of cars in Unit B, the answer is NO. Since all the passengers waiting for boarding cannot ride, the elevator car number detecting device 63 for the elevator cars of Units A and B can be boarded from the rated number of cars for Units A and B rather than the number of passengers waiting for the passenger number detecting device 64 on the Nth floor. It is determined whether the number of people is less than the total number of people (ST39).

  If the number of passengers waiting for boarding on the Nth floor passenger number detection device 64 is greater than the number of people waiting for the passengers in Units A and B, the total number of passengers in the elevator car number detection device 63 in Units A and B is subtracted. If YES, all passengers waiting for boarding on the Nth floor can board Units A and B, so both Units A and B stop on the Nth floor in response to the call (ST22).

  If the number of passengers waiting for boarding on the Nth floor passenger number detection device 64 is greater than the number of passengers rated for the cars in units A and B, the total number of passengers in the elevator car number detection device 63 in units A and B is subtracted. If NO, all the passengers waiting for the Nth floor cannot get on the Ath and Bth cars, so the Bth and Cth machines also stop on the Nth floor (ST40). Unit A also stops on the Nth floor (ST22).

  Finally, the elevator car assignment is terminated (ST23).

  According to the second embodiment of the present invention, the car is allocated by referring to the result of comparison between the boarding number detection device provided at the hall and the elevator car number detection device provided in the car. This can eliminate unnecessary car operation and improve elevator service.

  In addition, a more optimal car dispatch can be realized by performing car dispatch in a group management apparatus using a plurality of cars.

  Needless to say, the present invention is not limited to the embodiments described above and can be implemented with various modifications. For example, although the group management elevator of the present invention has been described with three elevators, it may be three or more.
