Description

  The present invention relates to an elevator system in which a user registers destination floor information before getting on an elevator.

  In recent years, ID cards, which are non-contact IC cards, have been used with a flapper gate equipped with a destination floor registration device with a personal identification device before boarding and a destination floor registration device equipped with a personal authentication device installed near the landing. After personal authentication, the elevator system that automatically registers the destination floor when the assigned elevator arrives is sent to the elevator after the destination floor read from the ID card, etc., or manually entered destination floor in the case of an authorized person. It has been.

  In addition, an elevator system in which a desired destination floor is automatically transmitted to an elevator control device without being operated by the user by an information transmitter carried by the user or by recognition of the user's characteristics. In order to give access to only certain floors or to influence the pre-selection of destination floors according to their own personal requirements and within their access authority. The user can pre-select a fixed destination floor, specify the destination floor according to his / her wishes and within the authorized range, and make the fixed destination floor a user each time recognition of personal characteristics is completed. For example, it is described in Patent Document 1.

  Furthermore, in an elevator control device that determines the assigned car in conjunction with the security gate of the building, even if the user cannot get on the assigned car for some reason after passing through the security gate, It is known to automatically register a destination call based on destination floor information for an assigned car when it is detected that a user has boarded the determined assigned car at a predetermined floor to enable use. For example, it is described in Patent Document 2.

  Furthermore, when the user registers the destination floor on the hall side, the user is guided to the elevator hall at the gate in order to guide the flow of the user until getting into the elevator more smoothly and to prevent the congestion of the elevator user at the time of congestion. It is known that the destination floor can be registered at the entrance part of the gate and the elevator assigned to the exit part is displayed, for example, as described in Patent Document 3.

JP 2000-289943 A International Publication No. WO2010 / 023723 Pamphlet JP 2011-126690 A

  In the above prior art, those described in any of the patent documents require that the user directly access the destination gate registration terminal device of the entrance gate or elevator hall in order to register the destination floor. There was a case where a user traffic jam occurred in the vicinity of the destination floor registration terminal device.

  Moreover, in the above-mentioned conventional technology, the number of users is estimated by registering the destination floor, and control for carrying out more efficient operation control is performed, but there is an error in estimating the number of users depending on the situation. As a result, there was a possibility that efficient operation control could not be implemented.

  For example, in Patent Document 2 and Patent Document 3, if there is a user who tries to board without using the destination gate registration terminal device of the security gate or elevator hall, the number of users grasped by the elevator system and Because of the difference between the number of people who actually use the elevator, there are cases where the user assigned to the car cannot get on. Similarly, when the user operates the destination floor registration terminal device a plurality of times, a difference between the number of elevator users and the actual number of users occurs.

  An object of the present invention is to solve the above-mentioned problems of the prior art and enable a smoother movement of the user, improve the estimation accuracy of the number of users, and improve the operation efficiency of the elevator system.

  In order to solve the above problems, the present invention has an elevator group management control device that manages the operation of a plurality of elevators, and in the elevator system that performs destination floor registration before entering the elevator, the elevator group management control device A communication terminal device that is established and connected, and an information terminal device that is carried by a user. The communication terminal device counts the number of established communications with the information terminal device, and is counted. The number of connections is transmitted to the elevator group management control device.

  According to the present invention, since the communication terminal device counts the number of established communication between the information terminal device carried by the user and the communication terminal device provided at the landing, it is possible to accurately detect the number of users on each floor. This makes it possible to reduce the load of the elevator group management control, and to assign elevators that are more appropriate to the user, for example, with less time, so that the elevator operation efficiency can be improved.

  FIG. 1 shows an overall configuration diagram of an elevator system, and number control devices 201, 202, and 20k that individually control a plurality of elevator numbers 301, 302, and 30k, and the overall operation efficiency of each elevator is optimized. And an elevator group management control device 100 for controlling the operation. In the elevator group management control device 100, operation data such as elevator information and destination floor information that change every moment is transmitted to the learning system 102, and the learning system 102 learns the traffic situation based on the operation data, and at that time Determine what driving program is right for you. The intelligent system 103 uses the learning results to generate a new feature mode and simulate an elevator operation, and automatically generate an optimal driving program corresponding to each traffic demand. The operation management control unit 101 uses an operation program to perform allocation control for determining which elevator is to be assigned to each destination floor, and also performs an allocation command for each destination floor to the elevator control system.

  A plurality of communication terminal devices 700 are installed near the landing on each floor, the entrance of a building, the entrance of an elevator hall, and the like. The communication terminal device 700 includes a communication unit 710, a connection establishment reply unit 711, a connection establishment number counting unit 712, and a reception data processing unit 713.

  The information terminal device 400 is carried by a user, and includes a communication unit 402, a call processing activation unit 403, a call communication processing unit 404, and a user / terminal information database 406. The call communication processing unit 404 includes a call candidate data acquisition unit 4041, a call data transmission unit 4042, an assigned car data reception unit 4043, and a screen display unit 4044. The call process activation unit 403, the call communication processing unit 404, and the user / terminal information database 406 are applications for performing call registration, and these are hereinafter collectively referred to as “call registration applications”.

Hereinafter, a flow until the user registers a car call using the information terminal device 400 will be described with reference to FIG.
A user carries the information terminal device 400 and approaches within the communication range of any of the communication terminal devices 701, 702, 70n,. At this time, the communication unit 402 of the information terminal device 400 performs communication connection with the communication unit 710 of the communication terminal device 700. As the communication here, wireless LAN communication is generally used, but communication may be connected also by a 3G line, LTE, or the like used in a wired LAN, a cellular phone, or the like.

  Here, it is assumed that the communication unit 402 of the information terminal device 400 and the communication unit 710 of the communication terminal device 700 establish a communication connection and establish a communication connection. That is, a state in which packets can be transmitted and received between the communication unit 402 and the communication unit 710 means establishment. This is a technique known in the TCP / IP protocol used for Internet communication, for example. In general, when communication is performed between transmitting and receiving terminals, when the receiving side is in a standby state for receiving information on the transmitting side (or in a monitoring state whether the transmitting side information is received), the transmitting side is a header for communication. The transmission source information (IP, terminal ID, sequence number, Mac address, etc.), communication permission signal, checksum, etc. are transmitted. The contents of the communication information after the header at this time generally transmit empty information. When the receiving side receives this information, the receiving side permits reception of the information on the transmitting side by a communication permission signal, and establishes a one-to-one transmission / reception path between the transmitting side and the receiving side.

  Next, when the communication connection between the information terminal device 400 and the communication terminal device 700 is established, the connection establishment reply unit 711 of the communication terminal device 700 generates a timer associated with the information of the information terminal device 400 with which the connection has been established. The information used to generate the timer is information that can specify the connection target such as the ID of the information terminal device, the user name, and the Mac address of the terminal. Here, FIG. 2 shows an example of a data table created and managed by the connection establishment reply unit 711 for each information terminal device 400 of the user. For each user ID, the connection elapsed time, timer remaining time, destination floor call data, and assigned car data are managed. If there is no destination floor call data and there is no remaining timer time, the data is sequentially discarded. In addition, data is discarded also for user ID information on which allocation car data, which will be described later, has arrived. Furthermore, instead of discarding the data, the user ID, destination floor call data, etc. may be stored and used for maintenance of the building / elevator. For example, if the statistics of destination floors frequently used by users are collected and stored, and usage data is sent to the maintenance center, the frequency of door usage can be estimated from the usage data, and maintenance can be performed before failure occurs. It becomes possible.

  When communication connection between information terminal device 400 and communication terminal device 700 is established, communication unit 402 of information terminal device 400 transmits a call process activation permission signal to call process activation unit 403. The call process activation unit 403 receives the call process activation permission signal, and activates the call communication processing unit 404 according to the usage status of the information terminal device 400. For example, when the user using the information terminal device 400 has started another application with a high priority, the call processing activation unit 403 does not immediately activate the call communication processing unit 404 and prepares for activation. Tell the user that is completed.

  When the call communication processing unit 404 is activated from the call process activation unit 403, the call processing communication unit 404 notifies the user that the preliminary processing communication unit 404 has been activated using the screen display unit 4044. When the call communication processing unit 404 is activated, the user can register a call using the information terminal device 400. The user transmits destination floor call data, which is the floor he / she wants to go, from the call data transmission unit. The communication unit 402 of the information terminal device 400 transmits the destination floor call data to the communication unit 710 of the communication terminal device 700.

  When the communication unit 710 of the communication terminal device 700 receives the destination floor call data, the communication terminal device 700 determines whether or not the time when the destination floor call data is received is within the timer set by the connection establishment reply unit 711. To do. If it is within the timer, the destination floor call data is transmitted to the operation management control unit 101 of the elevator group management control device 100.

  Next, the operation management control unit 101 performs an assignment process for determining which car to dispatch to the received destination floor call data, and assigns the assigned floor call data to the communication unit 710 of the communication terminal device 700. Send data. When the communication unit 710 of the communication terminal device 700 receives the assigned car data, the communication unit 710 of the communication terminal device 700 transmits the assigned car data to the communication unit 402 of the information terminal device 400.

The assigned car data receiving unit 4043 receives assigned car data from the communication unit 710 of the communication terminal device 700. The screen display unit 4044 displays destination floor data and assigned car data to be transmitted on the screen.
The machine control devices 201, 202, and 20k individually control the operation of each elevator under the control of the operation management control unit 101. For each elevator, information on events such as car load and door opening / closing is transmitted to the operation management control unit 101.

  The condition for terminating the communication connection between the information terminal device 400 and the communication terminal device 700 is terminated when the physical distance between the information terminal device 400 and the communication terminal device 700 is separated and the communication terminal device 700 reaches the outside of the communication range. Further, the communication connection may be released at the timing when the elevator user uses the elevator. This is implemented, for example, when the communication unit 710 of the communication terminal device 700 transmits a flag for ending the communication connection when the assigned car data is transmitted to the communication unit 402 of the information terminal device 400. Further, as a method for preventing the information terminal device 400 from re-establishing a connection with the communication terminal device and erroneously detecting the number of passengers at the landing, for example, a timer is provided on either the information terminal device 400 side or the communication terminal device 700 side. Using the method in which connection processing is not performed for a certain period of time during the timer period, or the connection of the information terminal device 400 used immediately before with the terminal ID, Mac address, or the like is released on the communication terminal device 700 side even if the connection is established. There are methods. In addition, when the user wants to use the elevator again at the above timing, it is preferable that the information is transmitted manually from the information terminal device 400 side, and the communication terminal device 700 receives and processes only the initiative information transmission.

  A method for counting the number of users at a landing using the communication terminal device 700 will be described with reference to FIG. Communication terminal apparatus 700 counts the number of communication connections between communication terminal apparatus 700 and information terminal apparatus 400 at connection establishment number counting section 712. The wireless LAN or wired LAN of the communication terminal device can count only users near the communication terminal device due to its local nature. Desirably, the communication terminal device 700 is preferably provided at a landing or an elevator hall on each floor so that the user waits for the elevator. However, when using a gate where the flow of the user is limited to some extent, A communication terminal device 700 may be provided. When counting the number of users, not only the number of communication connections but also the number of destination floor call data transmitted after communication is established may be counted.

  The communication unit 710 of the communication terminal device 700 transmits the number of users counted by the connection establishment number counting unit 712 every certain control cycle to the operation management control unit 101 of the elevator group management control device 100. By grasping the number of users on each floor, statistics and feature modes of the number of users for each floor as shown in FIG. 3 can be extracted with higher accuracy than in the past.

In FIG. 3, a determination processing unit (not shown) for determining whether the traffic demand, that is, whether the user's traffic situation is congested or not is described.
(A) is the number of people getting on and off by floor showing the flow of people in the building. The numbers on the vertical axis are the numbers on each floor, the right on the horizontal axis is the number of people getting on and off, It shows that there are many. The left side of the horizontal axis is the number of people going up, and this figure shows that the number of people getting on and off the first floor is the largest. The learning system 102 in the group management control system 100 learns the traffic situation based on the elevator information such as the car position and the number of passengers and the destination floor information, and determines which driving program is suitable at that time. Yes. Therefore, the number of people getting on and off by floor showing the flow of people in the building, from FIG. 2A to one of the feature modes (M1 to M6) showing the typical traffic information in the building from the online input information. Identify whether it belongs.

  As illustrated in (2) of FIG. 2, the feature modes M1 to M6 indicate the situation of traffic demand divided into six in this example on the coordinates where the horizontal axis is the number of people getting on and off and the vertical axis is the number of people getting on and off. It is shown. In the case of a normal office building, the area M1 with a small number of passengers both up and down is quiet, the area M3 with a large uphill condition is congested and up-peak, and the area with a large number of passengers is congested and is called a down-peak. The area is typically divided into areas as shown in the figure, but there are characteristics depending on the nature of the building, and new characteristics may be extracted from the collected traffic information. When a new feature is extracted, it is generated and registered as the feature mode Mn unique to the building, and the tendency of changes in the other feature modes M1 to M6 is learned.

  As described above, the determination processing unit can determine whether the traffic situation of the user is congested or quiet according to the traffic situation obtained by the learning system 102 and the feature modes M1 to M6. In addition to using the learning system 102, the determination processing unit may simply determine a time zone, for example, a busy hour in the morning, and a quiet daytime.

  FIG. 4 shows an example of the installation location of the input / output processing device. In (a), it is assumed that the input / output processing device 700 is installed on the ceiling of the elevator hall. As shown in (b), since the user P1 is in the communicable area A1 of the input / output processing device 700, communication between the information terminal device carried by the user P1 and the input / output processing device 700 is established, and the destination floor Call data is registered. On the other hand, since the user P2 is outside the communicable area A1 of the input / output processing device 700 and is moving away from this area, the information terminal device carried by the user P2 and the input / output processing device 700 communicate with each other. The destination floor call data cannot be registered. For this reason, only the user who is considered to use the elevator is registered with the destination floor call.

  According to the above, when the user carrying the information terminal device 400 approaches the elevator landing, the “call registration app” including the call communication processing unit 404 for performing elevator call registration is activated, It is possible to smoothly use the elevator without using the individual destination floor registration terminal provided.

  In addition, the communication terminal device 700 provided on each floor counts the number of communication connections with the information terminal device 400, whereby the number of elevator users on each floor can be measured, and more efficient elevator operation control is performed. It becomes possible to do.

  FIG. 5 is an overall configuration diagram of an elevator system according to another embodiment. A communication permission unit 407 is added to an internal block of the information terminal device 400, and a communication permission command unit 800 that performs mutual communication with the communication permission unit 407 is added. It has been configured.

  The operation of the communication permission unit 407 will be described. The communication permission unit 407 is for transmitting a permission signal for the communication unit 402 to perform communication, and the communication unit 402 cannot perform communication unless the communication permission unit 407 transmits a permission signal. At this time, the state of the communication unit 402 and the processing units associated with the communication unit 402 before the permission signal is transmitted may be in a standby state in which each processing is set to sleep. This is a function necessary for a portable terminal such as the information terminal device 400 to operate for a long time.

  Next, the operation of the communication permission command unit 800 will be described. The communication permission command unit 800 communicates with the communication permission unit 407, and transmits a “permit communication unit 402 to communicate” setting key to the communication permission unit 407 when a predetermined condition is satisfied. The predetermined condition here may be, for example, authentication information based on personal information in the information terminal device or a simple access key. If the authentication information is individual user / organization authentication information, the communication permission command unit 800 accesses the user / terminal information database 801 and confirms the presence or absence of the authentication information. In the case of a simple access key (encryption key), a process for verifying the encryption key is provided in the communication permission command part, and the setting key is transmitted only when the conditions match. In addition, the communication permission unit 407 that has received the setting key may perform a timer process including a timer that enables the setting key. By doing so, it is possible to prevent the communication unit and the process associated with the user from operating for a long time after receiving the setting key. The wireless terminal device on which the communication permission instruction unit 800 is mounted may be installed at the same position as the communication terminal device 700 provided at each landing, or may be installed at a gate of a building.

  Next, communication conditions of the communication permission command unit 800 and the communication permission unit 407 will be described. The communication method between the two processing units may be normal communication, but may preferably use short-range wireless communication (NFC) that is set in advance. By using NFC, communication between the communication permission command unit 800 and the communication permission unit 407 can be performed smoothly without performing initialization processing / protocol confirmation for communication in the two processing units.

  According to the above, by implementing the communication permission unit 407 in the information terminal device 400 and the communication permission command unit 800 at the landing or gate, it is possible to place the internal processing of the information terminal device 400 in a standby state. The use time of the information terminal device 400 can be improved.
