Description

  Embodiments described herein relate generally to an elevator control device, an elevator group management control device, an elevator system, and an elevator control method.

  Conventionally, when a hall call is registered in an elevator, a car assigned to the hall call responds. At that time, if the car is full before arriving at the answering floor of the hall call, no further boarding is possible, so the car passes without landing on the answering floor (hereinafter referred to as such answering floor). Is called "full passage").

  At this time, whether or not the car is full is determined by whether or not the amount of load applied to the car has reached a predetermined value. The car stops at the response floor and opens.

  However, depending on the user, when the car is landing and opened, there is a case where it is overlooked if it is crowded to some extent. When such a situation occurs, the operation efficiency of the elevator is reduced.

  The specification information storage unit 301 stores in advance specification information related to the No. X elevator 10X and the No. Y elevator 10Y, for example, usage, capacity of the cars 11X and 11Y, rated speed, and the like. These pieces of information may be acquired from the X-unit elevator single control device 12X and the Y-unit elevator single control device 12Y. The elevator information management unit 302A acquires operation status information of the X machine elevator 10X and the Y machine elevator 10Y from the X machine elevator single controller 12X and the Y machine single elevator controller 12Y. Examples of the driving status information include destination floor registration operation information on the in-car operation panels 111X and 111Y, load information on the cars 11X and 11Y, position information and traveling direction information on the cars 11X and 11Y, and the like.

  The waiting start time acquisition unit 303 uses the time point when the user identification information is acquired by the camera devices 22-1 to 22-n as the elevator waiting start time for each user at the landings 20-1 to 20-n on each floor. Get as. The boarding determination information output unit 304A is configured so that each of the cars 11X and 11Y is based on the information acquired by the elevator information management unit 302A and the elevator waiting start time for each user acquired by the waiting start time acquiring unit 303. Each time the door opens at any one of the landings 20, for each user at the landing, the waiting time from the waiting start time to the door opening, and information indicating whether or not the passenger has entered the opened doors 11X and 11Y The minimum boarding rate when the corresponding cars 11X and 11Y are open is acquired as boarding determination information, and is output to the boarding determination database 305. The boarding determination database 305 stores boarding determination information for each user output from the boarding determination information output unit 304A.

When a new hall call is accepted by the hall call accepting unit 306, the allocation evaluation value calculating unit 307, based on the driving situation information of the No. X elevator 10X and the No. Y elevator 10Y acquired by the elevator information management unit 302A, An evaluation value indicating the priority of assignment of the cars 11X and 11Y to the hall call is calculated. The assigned car determination unit 308 determines an assigned car for the hall call based on the evaluation value calculated by the assigned evaluation value calculation unit 307.

  When the boarding call reception unit 306 receives a new boarding call, the boarding judgment information acquisition unit 309 makes boarding judgment regarding the user whose identification information has been acquired by the camera device 22 installed on the floor where the boarding call is generated. Information is acquired from the boarding determination database 305.

  The user allowable boarding rate calculation unit 310A acquires, from the elevator information management unit 302A, the predicted arrival time of the car 11 that responds to the new hall call received by the hall call reception unit 306. Then, the estimated waiting time for each user of the corresponding hall is obtained from the elevator waiting start time for each user of the corresponding hall acquired by the waiting start time acquisition unit 303 and the predicted arrival time of the acquired car 11. calculate. In addition, based on the information acquired by the boarding determination information acquisition unit 309, the upper limit value of the boarding rate that permits boarding (hereinafter, “boarding” for each user and waiting time on the floor where the boarding call occurred) A boarding allowable boarding ratio graph indicating “allowable boarding ratio” is generated. Then, based on the generated boarding allowable boarding rate graph and the calculated predicted waiting time for each user, the boarding allowable boarding rate for the corresponding car 11 for each user on the corresponding floor is calculated. . The boarding allowable boarding rate calculation unit 311 calculates the boarding allowable boarding rate for the boarding 20 based on the boarding allowable boarding rate for each user calculated by the user allowable boarding rate calculation unit 310A.

  The control command output unit 312 outputs a response command to the landing call to the elevator single control device 12 corresponding to the car 11 assigned by the assigned car determination unit 308.

It is determined whether or not the boarding allowable boarding rate of the hall 20 is exceeded. As a result of the determination, when the boarding rate of the car 11 exceeds the boarding allowable boarding rate of the hall 20, an instruction for allowing the car 11 to pass through the hall 20 without landing on the hall 20 is provided. Output to the single controller 12.

<Operation of the elevator system according to the first embodiment>
Next, as an example of the operation of the elevator system 1A according to the present embodiment, (1) a process for learning a user's usage tendency is executed when the elevator user A comes to the landing 20-1 on the first floor. , (2) hall call assignment processing, and (3) full passage judgment processing will be described.

(1) Processing for Learning User Usage Trends Processing for learning usage trends for each user, which is executed in the elevator system 1A, will be described with reference to the sequence diagram of FIG. First, in the elevator information management unit 302A of the elevator group management control device 30A, information on the capacity of the car 11X of the No. X elevator 10X and the car 11Y of the Y elevator 10Y is acquired from the specification information storage unit 301 (S1). ). In addition, the operation status information of the No. X elevator 10X and the No. Y elevator 10Y is acquired at predetermined time intervals from the No. X elevator single control device 12X and the No. Y elevator single control device 12Y, respectively. The driving status information of the No. X elevator 10X and the No. Y elevator 10Y includes load information of the car 11X and the car 11Y. When the driving information is acquired by the elevator information management unit 302, the boarding rates of the cars 11X and 11Y are calculated based on the capacity information and the load information of the cars 11X and 11Y (S2).

  Next, when the elevator user A comes to the landing 20-1 on the first floor, the camera device 22-1 acquires the identification information of the user A from the imaging information. The identification information of the user A acquired by the camera device 22-1 is transmitted to the elevator group management control device 30A.

  In the elevator group management control device 30A, the identification information of the user A of the hall 20-1 transmitted from the camera device 22-1 is acquired by the waiting start time acquisition unit 303 and the boarding determination information output unit 304A. In the waiting start time acquisition unit 303, measurement of the waiting time of the elevator at the landing 20-1 of the user A is started. The elevator waiting time may be measured at the timing when the identification information of the user A is acquired, or after the identification information of the user A is acquired, the hall call is operated on the hall operation panel 21-1. May be started at the timing.

  When the hall operation panel 21-1 is operated by the user A and a hall call is generated, and one of the cars 11X and 11Y reaches the hall 20-1 and opens the door in response, the user A The time from the start of the waiting time measurement until the time when the car opens is acquired as the waiting time of the user A and is output to the boarding determination information output unit 304A (S3).

  In the boarding determination information output unit 304A, when the information on the waiting time of the user A is acquired from the waiting start time acquisition unit 303, the minimum boarding rate when the corresponding car 11 is opened is determined from the elevator information management unit 302A. To be acquired. The minimum boarding rate when the car 11 is open is acquired as the boarding rate of the car 11 when it is determined whether or not the user A gets in. In addition, it indicates whether or not the load applied to the corresponding car 11 has increased while the door is open, or whether or not the user A has entered the car 11 by analyzing the imaging information of the camera device 22-1. Information is acquired (S4).

  Then, the waiting time of the user A, the minimum boarding rate when the car 11 is opened, and information indicating whether the user A has entered the car 11 that has opened the door are acquired as boarding determination information. Is output to the boarding determination database (S5). In this way, whenever each of the cars 11X and 11Y opens at any one of the landings 20, the corresponding boarding determination information is acquired for each user at the landing 20 and is output to the boarding determination database 305. . Then, the boarding judgment information for each user output from the boarding judgment information output unit 304A is sequentially stored in the boarding judgment database 305, thereby accumulating past elevator usage statuses (S6).

  An example of the boarding determination information stored in the boarding determination database 305 is shown in FIG. In FIG. 4, for each of users A, B... Z, the waiting time and the minimum boarding rate when the car 11 is opened are stored each time the elevator 20 is waited for use at one of the landings 20. In addition, information indicating whether or not the user A has entered the opened car 11 and the recording date and time of the information are shown. For example, it is shown that the user A gets into the car 11 with a boarding rate of 30% at the timing of 4 seconds waiting time at 9:10:32 on May 30, 2015.

  Since the storage capacity of the boarding determination database 305 is finite, existing information is overwritten with new information as necessary. For example, when the number of recordable users is set to 26 and the number of pieces of information that can be stored for each user is set to 10, the 10 boarding determination information related to the user A and the 6 information related to the user B It is assumed that the boarding determination information of 26 users A to Z including boarding determination information is already stored in the boarding determination database 305.

  In this state, when the new boarding determination information a regarding the user A is acquired, the waiting time equal to the waiting time “4 seconds” indicated by the boarding determination information a is included in the existing information of the user A. The boarding determination information is overwritten with new boarding determination information a. When there is no boarding determination information with the same waiting time in the existing information of the user A, the oldest boarding determination information among the users A is overwritten with new boarding determination information a. Here, if the waiting time is compared with a numerical value obtained by dividing the waiting time in a short time such as 1 second, the probability that the waiting time of the new information matches the existing information is considerably reduced. You may make it compare by the numerical value divided by.

  Further, when the boarding determination information aa of the new user AA is acquired, the information on the oldest user whose last update date and time is earlier than a predetermined period (for example, several years or months) among the existing information. Is deleted, and information on the new user AA is stored. When there is no user information whose last update date is earlier than the predetermined period in the existing information, the user B with the smallest amount of recorded information is a temporary user with a low usage frequency. The corresponding information is erased and the information aa of the new user AA is stored. However, if the user information with a small amount of information is deleted, in the case of a building where the storage capacity of the boarding determination database 305 is insufficient for the number of regular users, the information on the new user is deleted immediately after saving. There is a high possibility that the situation will occur frequently and it will be difficult to keep information. For this reason, when information on a user with a small amount of information is deleted, it may be detected as a minor error and information for enlarging the storage capacity may be notified.

(2) Hall call assignment process When elevator user A arrives at hall 20-1 on the first floor, it is executed by elevator system 1A in parallel with the process of learning user usage trends in (1). The hall call assignment process will be described with reference to the sequence diagram of FIG.

  When the user A who has arrived at the hall 20-1 performs a call registration operation on the hall operation panel 21-1, the hall call reception unit 306 of the elevator group management control device 30A receives the call registration operation. The information of the accepted hall call is output to the allocation evaluation value calculation unit 307 and the boarding determination information acquisition unit 309 (S11).

  In the assigned evaluation value calculation unit 307, when information of a new hall call is acquired from the hall call reception unit 306, the allocation evaluation value calculation unit 307 is based on the driving status information of the No. X elevator 10X and the No. Y elevator 10Y acquired by the elevator information management unit 302A. Thus, an evaluation value indicating the priority of the assignment of the cars 11X and 11Y to the hall call is calculated. The evaluation value of each car 11X, 11Y is a value that evaluates to which car 11 a newly registered hall call should be assigned. For example, the earlier the predicted arrival time of each car at the corresponding hall 20 is, Calculated with a high value. Information on the calculated evaluation value is output to the assigned car determination unit 308 (S12, S13).

  The assigned car determination unit 308 determines the assigned car for the hall call based on the evaluation value calculated by the assigned evaluation value calculation unit 307. Here, it is assumed that the car 11X is determined as the assigned car. Information on the determined assigned car 11X is output to the control command output unit 312 and the user allowable boarding rate calculation unit 310A (S14).

  The control command output unit 312 outputs a response command for the landing call to the elevator single control device 12X corresponding to the car 11X determined as the assigned car (S15). This is the end of the description of the hall call assignment process.

(3) Full Passage Judgment Process As described above, the full pass judgment process executed when a new hall call is registered will be described with reference to the sequence diagram of FIG.

  When the information on the hall call is output from the hall call reception unit 306, the boarding determination information acquisition unit 309 causes the camera device 22-1 on the first floor where the hall call has occurred to the user on the hall 20-1. Identification information is acquired. Here, it is assumed that identification information of five users A to E has been acquired as the users at the landing 20-1. Then, the boarding determination information regarding the users A to E is acquired from the boarding determination database 305. Here, the average boarding determination information created in advance is used for a user who does not store boarding determination information for using the building for the first time. The acquired boarding determination information of the users A to E is output to the user allowable boarding rate calculation unit 310A (S16).

  In the user allowable boarding rate calculation unit 310A, the predicted arrival time of the car 11X responding to the new hall call is acquired from the elevator information management unit 302A. Then, from the elevator waiting start time for each user A to E of the corresponding hall 20-1 acquired by the waiting start time acquisition unit 303 and the predicted arrival time of the acquired car 11X, the corresponding hall 20-1 is obtained. The predicted waiting time for each of the users A to E is calculated (S17). Further, based on the information acquired by the boarding determination information acquisition unit 309, the boarding allowable boarding rate indicating the boarding allowable boarding rate at each waiting time for each of the users A to E of the hall 20-1 where the boarding call has occurred. A graph is generated.

  The generation process of the allowable boarding rate graph will be described with reference to FIG. First, as shown in FIG. 6 (a), a graph is generated for each user, with the waiting time on the horizontal axis and the car occupancy rate on the vertical axis, and the waiting time when boarding in the past use and A circle mark is plotted at a position corresponding to the boarding rate, and a cross mark is plotted at a position corresponding to the waiting time and boarding rate when the vehicle is not boarded. Next, from the graph of FIG. 6A, a curve indicating the boundary between the region where the circle is plotted and the region where the symbol is plotted is obtained as shown in FIG. 6B. A boarding allowable boarding rate graph indicating the boarding rate is generated. The boarding allowable boarding rate graph is generated for each of the users A to E at the hall 20-1.

  In the boarding allowable boarding rate graph as shown in FIG. 6B, it is considered that the boarding allowable boarding rate tends to be higher as the waiting time is longer. Also, a user whose curve in the graph is closer to the upper end is more likely to get in even if the boarding rate is higher, and a user who is closer to the lower end is more likely to wait even for a long time until the empty car 11 comes. Conceivable.

  And based on the generated boarding allowable boarding rate graph of the users A to E and the predicted waiting time for each of the users A to E, the boarding allowable boarding into the car 11X for each of the users A to E A rate is calculated. The calculated boarding allowable boarding ratio for each user A to E is output to the hall allowable boarding ratio calculating unit 311 (S18).

  The boarding allowable boarding rate calculation unit 311 calculates the boarding allowable boarding rate related to the boarding 20-1 based on the boarding allowable boarding rate for each of the users A to E calculated by the user allowable boarding rate calculation unit 310A. . The calculated boarding allowable boarding rate relating to the landing 20-1 is output to the control command output unit 312 (S19).

  Based on the information acquired by the elevator information management unit 302A, the control command output unit 312 determines the boarding rate of the car 11X assigned by the car assignment determining unit 308, and the hall calculated by the hall allowable boarding rate calculation unit 311. It is determined whether or not the boarding allowable boarding ratio of 20-1 is exceeded. As a result of the determination, when the boarding rate of the car 11X exceeds the boarding allowable boarding rate of the hall 20-1, an instruction for passing the car 11X to the hall 20-1 without being landed is given. And output to the corresponding elevator single control device 12X (S20).

  Here, in the hall allowable boarding rate calculation unit 311, as the boarding allowable boarding rate of the hall 20-1, the maximum value, the minimum value, or the maximum boarding allowable boarding rate into the car 11 </ b> X for each of the users A to E, or It is conceivable to use the median.

  If the maximum value among the boarding allowable boarding rates for the passengers 11 to 11X for each of the users A to E is used as the boarding allowable boarding rate for the hall 20-1, there is a high possibility that all people will board the car, but no one will board. . For example, as shown in FIG. 7A, the allowable boarding rate for user A is 70%, the allowable boarding rate for user B is 60%, and the allowable boarding rate for user C is 50%. %, The allowable boarding rate for the user D is 65%, and the allowable boarding rate for the user E is 63%. In this case, when the boarding allowable boarding rate 70% of the user A, which is the maximum value among these five people, is used as the boarding allowable boarding rate of the hall 20-1, as shown in FIG. When the boarding rate of the car 11X assigned to is 75%, it exceeds the calculated boarding allowable boarding rate 70% of the hall 20-1, so a control instruction is issued to allow the car 11X to pass through. Is output. Then, when a new car 11Y is assigned to the hall call and the boarding rate of the car 11Y is 68%, the boarding allowable boarding rate of the boarding area 20-1 is less than 70%. Then, a control instruction is output so that the car 11Y responds to the hall 20-1. In this case, the user A having a boarding allowable boarding rate of 70% is likely to board the responding car 11Y, but other users B to E (particularly, the users B and C) can board the car. The nature is low.

  Moreover, if the minimum value among the boarding allowable boarding rates into the car 11X for each of the users A to E is used as the boarding allowable boarding rate for the hall 20-1, there is a high possibility that the user will wait for a long time. For example, when the boarding allowable boarding rate 50% of the user C, which is the minimum value among the five users shown in FIG. 7A, is used as the boarding allowable boarding rate of the hall 20-1, FIG. ) When the boarding rate of the first assigned car 11X is 55%, it exceeds the calculated boarding allowance rate of 50% for the landing 20-1, so the car 11X is full. A control instruction is output so as to pass. When a new car 11Y is assigned to the hall call and the boarding rate of the car 11Y is 48%, the boarding allowance rate for the boarding area 20-1 is less than 50%. Then, a control instruction is output so that the car 11Y responds to the hall 20-1. In this case, the passengers A, B, D, and E may pass through the first assigned car 11X despite the high possibility of getting in, and the driving efficiency may be reduced. For this reason, it is considered appropriate to use the maximum value among the boarding allowable boarding rates for the users A to E as the boarding allowable boarding rates for the corresponding halls 20-1.

  According to the first embodiment described above, when the elevator responds to the hall call, the occupancy rate of the car, which is a condition for determining whether or not to pass the car fully, is set to the usage tendency of the users at the hall. By deciding together, it is possible to reduce unnecessary car stops and improve driving efficiency. In particular, this embodiment has a high affinity with a system having a user authentication function such as a DCS system, and by using such a system, it is possible to operate an elevator more efficiently and conveniently.

<< Second Embodiment >>
In the second embodiment of the present invention, a case where a plurality of elevator systems are installed in a large-scale building will be described. In such a case, there is a high possibility that users are common in a plurality of buildings. Therefore, in the second embodiment described below, the learning efficiency of the user's usage tendency is improved by configuring so that one boarding determination database is shared by a plurality of elevators.
