Description

[Technical Field]

[0001] The present disclosure relates to elevator systems. [Background technology]

[0002] Conventionally, there is an elevator system in which both a robot server that controls a robot and a security management device that manages facility security work together with the same elevator. For example, Patent Document 1 describes an elevator system that includes a mobile object control device that is a robot server and a security management device that manages restrictions on call registration. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 7359282 Summary of the Invention [Problem to be solved by the invention]

[0004] In the elevator system described in Patent Document 1, when a robot arrives at a hall and there is a restriction on the floor the robot can board, the robot server sends a request to the security management device to remove the restriction. To realize such a conventional elevator system, direct communication between the robot server and the security management device is required. Therefore, both the robot manufacturer and the security manufacturer must consider the communication specifications between the robot server and the security management device and implement communication functions. The conventional elevator system described in Patent Document 1 has the problem of being difficult to implement.

[0005] The present disclosure is intended to solve the above-mentioned problems. The purpose of the present disclosure is to reduce the difficulty for users, such as manufacturers, to implement an elevator system in which both a robot server and a security management device are linked to the same elevator. [Means for solving the problem]

[0006] An elevator system according to the present disclosure includes a robot server that controls a robot, a security management device that can request the lifting of security restrictions on specific elevator floors, an elevator group control device that restricts and lifts security restrictions on specific elevator floors, and a relay device that communicates with the robot server, the security management device, and the elevator group control device. When the relay device receives a security lift request from the robot server, it transmits the lift request to the security management device so that it may be forwarded. When the security management device receives a security lift request from the relay device, it relays the lift request to the elevator group control device via the relay device. When the elevator group control device receives the security lift request from the relay device, it lifts the security restriction and transmits a security lift response to the relay device. [Effects of the Invention]

[0007] According to the present disclosure, in an elevator system in which both a robot server and a security management device are linked to the same elevator, the difficulty of implementation by users such as manufacturers can be reduced. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments will be described with reference to the accompanying drawings. In each drawing, the same or corresponding parts are designated by the same reference numerals. In this disclosure, duplicated descriptions will be simplified or omitted as appropriate. For convenience, in the following description, the positional relationship of each structure may be expressed based on the illustrated state. Note that this disclosure is not limited to the following embodiments and their variations. Any components described in the following embodiments and their variations can be freely combined, modified, or omitted within the scope of the present disclosure.

[0010] Embodiment 1 Fig. 1 is a diagram showing the overall configuration of an elevator system according to embodiment 1. Fig. 2 is a block diagram showing the functional configuration of the elevator system according to embodiment 1. The elevator system according to this embodiment is composed of a robot server 2, a security management device 3, a relay device 5, and an elevator group control device 7.

[0011] The elevator system according to this embodiment is applied to a facility. The facility may be, for example, an indoor facility, an outdoor facility, or a facility that combines these. The facility may consist of, for example, one or more buildings. The facility may also be, for example, a part of a building. The facility has multiple floors.

[0012] In a facility to which the elevator system according to this embodiment is applied, a robot 1 operates. A plurality of robots 1 may operate in the facility. The robot 1 communicates wirelessly with a robot server 2 when it is inside an elevator car 11 or at a landing 16 installed in the facility. The robot server 2 controls the robot 1 via wireless communication. The robot server 2 manages, for example, the movement of the robot 1 and the services provided by the robot 1. Some or all of the robot server 2 may be located within the facility, or may be located outside the facility. Some or all of the functions of the robot server 2 may be implemented on a virtual machine of a cloud service, or may be implemented using storage or processing resources on the cloud service.

[0013] In a facility, at least one specific floor is set as a security floor. A security floor is a floor where entry of human users and robots 1 is controlled. In a facility, multiple floors may be set as security floors. Elevators are used by users and robots 1 to move between multiple floors in the facility. Elevator landings 16 are provided on each floor.

[0014] An elevator car 11 is connected to a hoisting machine 13, a deflector sheave 14, and a counterweight 15 via wire ropes 12. The car 11 and counterweight 15 are installed inside an elevator shaft 18 provided in the facility. The hoisting machine 13 and the deflector sheave 14 are installed inside a machine room 19 provided in the facility.

[0015] The facility is provided with, for example, a plurality of cars 11. The running of each car 11 is controlled by an elevator car controller 9. The elevator car controller 9 and the car 11 are connected via a cable 10.

[0016] The elevator car controllers 9 are connected to the elevator group controller 7 via a transmission cable 8. The elevator group controller 7 controls the running of multiple cars 11 by controlling each of the elevator car controllers 9. The elevator group controller 7 controls the operation of the entire elevator system.

[0017] The security management device 3 is a device that manages security in a facility. The security management device 3 can request the lifting of security restrictions on elevators at specific floors. The security management device 3, for example, manages restrictions on call registrations in which the car 11 stops at a security floor. For example, the elevator group control device 7 restricts the acceptance of call registrations in which the car 11 stops at a security floor by users who are not permitted to enter the security floor. The security management device 3 releases the restrictions imposed by the elevator group control device 7 by outputting a signal requesting the lifting of the restrictions. The security management device 3 also releases the restrictions imposed by the elevator group control device 7 by outputting a command signal to restore the restrictions.

[0018] The robot server 2 is connected to the relay device 5 wirelessly or via a cable 4. Similarly, the security management device 3 is connected to the relay device 5 wirelessly or via a cable 4. The relay device 5 is also connected to the elevator group control device 7 via an elevator shaft transmission cable 6. The relay device 5 communicates with each of the robot server 2, the security management device 3, and the elevator group control device 7.

[0019] For example, when the relay device 5 receives a signal such as a call registration request from the robot server 2, it transmits the signal to the elevator group control device 7. Furthermore, when the relay device 5 receives a signal such as a request to lift security restrictions from the security management device 3, it transmits the signal to the elevator group control device 7. The relay device 5 relays communications between the robot server 2 and the elevator group control device 7, and between the security management device 3 and the elevator group control device 7.

[0020] The robot server 2, security management device 3, cable 4, and relay device 5 are installed, for example, in a facility manager's room 17. The elevator group management device 7, transmission cable 8, and elevator car control device 9 are installed, for example, inside a machine room 19.

[0021] 1, the robot 1 communicates with the relay device 5 via the robot server 2. The robot 1 and the relay device 5 may also be configured to communicate directly without the robot server 2.

[0022] As shown in Figure 2, the robot server 2 has a transmitter 2A and a receiver 2B. The relay device 5 has a transmitter 5A, a receiver 5B, a release request response recording unit 5C, and a release request response matching unit 5D. The security management device 3 has a transmitter 3A and a receiver 3B. The elevator group control device 7 has a transmitter 7A, a receiver 7B, a security release unit 7C, and a call registration allocation unit 7D.

[0023] The transmitter 2A of the robot server 2 has the function of transmitting signals, such as a request from the robot 1 to release security at the boarding floor, a request from the robot 1 to release security at the destination floor, a request from the robot 1 to register a boarding floor call, and a request from the robot 1 to register a destination floor call, to the receiver 5B of the relay device 5. At this time, the transmitter 2A transmits various signals as signals including a robot ID, which is an identifier that identifies the robot 1.

[0024] The receiving unit 2B of the robot server 2 has the function of receiving from the transmitting unit 5A of the relay device 5 a response to deactivate security at the boarding floor, a response to deactivate security at the destination floor, a response to call registration at the boarding floor, and a response to call registration at the destination floor.

[0025] The transmitting unit 3A of the security management device 3 has a function of transmitting each of a request to deactivate security for the boarding floor and a request to deactivate security for the destination floor to the receiving unit 5B of the relay device 5. The receiving unit 3B of the security management device 3 has a function of receiving each of the request to deactivate security for the boarding floor transferred from the transmitting unit 5A of the relay device 5, the response to deactivate security for the boarding floor transmitted from the transmitting unit 5A of the relay device 5, the request to deactivate security for the destination floor transferred from the transmitting unit 5A of the relay device 5, and the response to deactivate security for the destination floor transmitted from the transmitting unit 5A of the relay device 5.

[0026] The transmitter 5A of the relay device 5 has the function of transmitting each of the following to the receiver 2B of the robot server 2, the receiver 3B of the security management device 3, or the receiver 7B of the elevator group management device 7: a request to release security at the boarding floor, a response to release security at the boarding floor, a request to register a call at the boarding floor, a response to register a call at the boarding floor, a request to release security at the destination floor, a response to release security at the destination floor, a request to register a call at the destination floor, and a response to register a call at the destination floor.

[0027] The receiving unit 5B of the relay device 5 has the function of receiving each of the following: a request to release security for the boarding floor from the transmitting unit 2A of the robot server 2, a request to release security for the boarding floor from the transmitting unit 3A of the security management device 3, a response to the release of security for the boarding floor from the transmitting unit 7A of the elevator group control device 7, a request to register a call for the boarding floor from the transmitting unit 2A of the robot server 2, a response to the registration of a call for the boarding floor from the transmitting unit 7A of the elevator group control device 7, a request to release security for the destination floor from the transmitting unit 2A of the robot server 2, a request to release security for the destination floor from the transmitting unit 3A of the security management device 3, a response to the release of security for the destination floor from the transmitting unit 7A of the elevator group control device 7, a request to register a call for the destination floor from the transmitting unit 2A of the robot server 2, and a response to the registration of a call for the destination floor from the transmitting unit 7A of the elevator group control device 7.

[0028] The release request response recording unit 5C has a function of recording the content of the signal requesting deactivation of security at the boarding floor or destination floor transmitted from the transmitting unit 2A of the robot server 2, and the content of the signal responding to the deactivation of security at the boarding floor or destination floor transmitted from the transmitting unit 7A of the elevator group control device 7. The release request response recording unit 5C records the content of the signal requesting deactivation of security transmitted from the robot server 2 and the content of the signal responding to the deactivation of security transmitted from the elevator group control device 7 after linking them together. The release request response recording unit 5C records at least one of, for example, the robot ID, which is an identifier that identifies the robot 1, the success or failure of the security deactivation response, the floor on which security was deactivated, the time the security deactivation request was received, and the time the security deactivation response was received.

[0029] The release request response collating unit 5D collates the content of the signal requesting deactivation of security for the boarding floor or destination floor, transmitted from the transmitting unit 2A of the robot server 2, with past records recorded in the release request response recording unit 5C. Depending on the collation result, specifically whether or not the signal matches specified conditions described below, the release request response collating unit 5D selects whether to transfer the security deactivation request signal so that it is relayed through the security management device 3, or to transfer the security deactivation request signal directly to the elevator group control device 7 without relaying it through the security management device 3.

[0030] The transmitter 7A of the elevator group control device 7 has a function of transmitting each of the boarding floor security release response, the boarding floor call registration response, the destination floor security release response, and the destination floor call registration response to the receiver 5B of the relay device 5. The receiver 7B of the elevator group control device 7 has a function of receiving each of the boarding floor security release request from the transmitter 5A of the relay device 5, the boarding floor call registration request from the transmitter 5A of the relay device 5, the destination floor security release request from the transmitter 5A of the relay device 5, and the destination floor call registration request from the transmitter 5A of the relay device 5.

[0031] The security release unit 7C has a function to receive a request to release security for a boarding floor and release the security restrictions for the corresponding boarding floor, and a function to receive a request to release security for a destination floor and release the security restrictions for the corresponding destination floor. The call registration allocation unit 7D has a function to select one of the elevator car controllers 9 connected to the elevator group management device 7 and call register the boarding floor, and a function to select one of the elevator car controllers 9 connected to the elevator group management device 7 and call register the destination floor.

[0032] FIG. 3 is a diagram illustrating an example of the hardware configuration of the main components of the elevator system according to the first embodiment. The functions of the main components of the elevator system, namely, the robot server 2, the security management device 3, the relay device 5, and the elevator group control device 7, can be realized by processing circuits. The processing circuits include, for example, a ROM 20a (Read Only Memory), a RAM 20b (Random Access Memory), an EEPROM 20c (Electrically Erasable Programmable Read-Only Memory), and a CPU 20d (Central Processing Unit). The ROM 20a stores programs executed on the elevator system. The RAM 20b stores working information, such as temporary storage of communication packet data. The EEPROM 20c stores information such as playback command data and command response data. The CPU 20d executes the programs stored in the ROM 20a. Some or all of the processing circuits may be configured by dedicated hardware. Some or all of the processing circuits may be configured by software, firmware, or the like.

[0033] In the elevator system according to this embodiment, each device, such as the robot server 2, the security management device 3, the relay device 5, and the elevator group control device 7, reads a program recorded on a recording medium and operates in accordance with the program to execute each function. The recording medium on which the program is recorded may be, for example, built into the processing circuit of each device, or may be connected to each device, or may be read by a reading device such as a drive of each device. The program may be a software package containing multiple pieces of software that run on each of the multiple devices that make up the elevator system.

[0034] 4 is a flowchart showing an example of a series of operations during initial communication in the elevator system according to embodiment 1. First, when robot 1 arrives at the landing (step S301), transmitter 2A of robot server 2 transmits a request to deactivate security at the boarding floor to receiver 5B of relay device 5 as a signal including information on the robot ID, which is an identifier that identifies the robot (step S302). Deactivation request response recording unit 5C of relay device 5 records information in the request to deactivate security at the boarding floor, such as the robot ID, the floor for which security deactivation is requested, and the time the security deactivation request was received (step S303).

[0035] Next, the transmitting unit 5A of the relay device 5 transmits a request to release security at the boarding floor to the receiving unit 3B of the security management device 3 so that the request can be transferred (step S304). The transmitting unit 3A of the security management device 3 transmits the request to release security at the boarding floor to the receiving unit 5B of the relay device 5 (step S305).

[0036] Next, a request to release the security for the boarding floor is transmitted from the transmitting unit 5A of the relay device 5 to the receiving unit 7B of the elevator group control device 7 to be relayed and forwarded (step S306). The security release unit 7C of the elevator group control device 7 releases the security restriction for the corresponding boarding floor (step S307). Then, a response to release the security for the boarding floor is transmitted from the transmitting unit 7A of the elevator group control device 7 to the receiving unit 5B of the relay device 5 (step S308).

[0037] The deactivation request response recording unit 5C of the relay device 5 records the content of the deactivation response for the boarding floor in association with the content of the security deactivation request recorded in the process of step S303 (step S309). For example, information on the success or failure of the security deactivation response and the time of reception may be recorded.

[0038] Next, the transmitter 5A of the relay device 5 transmits a security release response for the boarding floor to the receiver 3B of the security management device 3 and the receiver 2B of the robot server 2 so that they may be transferred (steps S310 and S311). By the processing of steps S301 to S311, the security restriction for the boarding floor of the robot 1 is released.

[0039] Next, a boarding floor call registration request is transmitted from the transmitter 2A of the robot server 2 to the receiver 5B of the relay device 5 (step S312). Then, the transmitter 5A of the relay device 5 transmits the boarding floor call registration request to the receiver 7B of the elevator group control device 7 so that it may be forwarded (step S313). The call registration allocation unit 7D of the elevator group control device 7 selects one of the elevator car controllers 9 connected to the elevator group control device 7 and performs boarding floor call registration (step S314). Then, the transmitter 7A of the elevator group control device 7 transmits information about the assigned car 11 and whether the call registration was successful or not to the receiver 5B of the relay device 5 as a boarding floor call registration response (step S315). The transmitter 5A of the relay device 5 transmits the boarding floor call registration response to the receiver 2B of the robot server 2 so that it may be forwarded (step S316).

[0040] When the robot 1 gets into the car 11 (step S317), the transmitter 2A of the robot server 2 transmits a request to deactivate security at the destination floor to the receiver 5B of the relay device 5 as a signal including information about the robot ID that identifies the robot 1 (step S318). The deactivation request response recording unit 5C of the relay device 5 records information in the request to deactivate security at the destination floor, such as the robot ID, the floor for which security deactivation is requested, and the time the security deactivation request was received (step S319).

[0041] Next, a request to release security for the destination floor is transmitted from the transmitting unit 5A of the relay device 5 to the receiving unit 3B of the security management device 3 so as to be forwarded (step S320). Then, in step S321, the request to release security for the destination floor is transmitted from the transmitting unit 3A of the security management device 3 to the receiving unit 5B of the relay device 5 so as to be relayed.

[0042] Next, a request to release security for the destination floor is transmitted from transmitter 5A of relay device 5 to receiver 7B of elevator group control device 7 to be transferred (step S322). Security release unit 7C of elevator group control device 7 releases the security restriction for the corresponding destination floor (step S323). Then, transmitter 7A of elevator group control device 7 transmits a response to release security for the destination floor to receiver 5B of relay device 5 (step S324).

[0043] The deactivation request response recording unit 5C of the relay device 5 records the deactivation response to the security for the destination floor in association with the content of the security deactivation request recorded in the process of step S319 (step S325). For example, the success or failure of the security deactivation response and the time of reception may be recorded.

[0044] Next, the transmitter 5A of the relay device 5 transmits a response to the receiver 3B of the security management device 3 and the receiver 2B of the robot server 2 to transfer the response (steps S326 and S327). The processing of steps S317 to S327 above removes the security restriction on the destination floor of the robot 1.

[0045] Next, a destination floor call registration request is transmitted from transmitter 2A of robot server 2 to receiver 5B of relay device 5 (step S328). Then, transmitter 5A of relay device 5 transmits the destination floor call registration request to receiver 7B of elevator group control device 7 so that it may be forwarded (step S329). Call registration allocation unit 7D of elevator group control device 7 registers the destination floor call in one of the individual elevator control devices 9 connected to the elevator group control device 7 (step S330).

[0046] In step S331, the transmitter 7A of the elevator group control device 7 transmits information about the assigned car 11 and whether the call registration was successful as a destination floor call registration response to the receiver 5B of the relay device 5. In addition, the transmitter 5A of the relay device 5 transmits a request to the receiver 2B of the robot server 2 to transfer the destination floor call registration response (step S332). After the elevator car 11 arrives at the destination floor, the robot 1 disembarks (step S333).

[0047] Fig. 5 is a flowchart showing an example of a series of operations during second and subsequent communications in the elevator system according to embodiment 1. Fig. 6 is a table showing an example of past records in the release request response recording unit 5C in the elevator system according to embodiment 1. The processes from step S301 to step S303 in Fig. 5 are the same as the series of operations for the initial communication shown in Fig. 4, and therefore detailed description thereof will be omitted.

[0048] The release request response collating unit 5D of the relay device 5 collates the content of the request to release the security for the boarding floor recorded in the process of step S303 with the content previously recorded in the release request response recording unit 5C (step S401).

[0049] In the process of step S401, the release request response collating unit 5D of the relay device 5 determines whether at least one of the following conditions (1) to (3) is satisfied, for example.

[0050] Condition (1) The time when the security release request was received is within a reference time (for example, 24 hours) from the latest time of the security release response recorded in the release request response recording unit 5C. Condition (2): The robot ID included in the received signal requesting release of security exists in the past records of the release request response recording unit 5C. Condition (3) The floor for which the deactivation request was made in the received security deactivation request exists in the past records of the deactivation request response recording unit 5C and has been successfully deactivated.

[0051] If any of the above conditions (1) to (3) is satisfied, a signal requesting deactivation of the security at the boarding floor is transferred directly to the elevator group control device 7 without being relayed through the security control device 3 (step S402). In the example shown in Fig. 6, the security deactivation request for "No. 5" satisfies the above conditions (1) to (3) for the past record "No. 3". If the condition is not satisfied, the process of step S304 in the series of operations for the initial communication shown in Fig. 4 is carried out, and the series of processing flows shown in Fig. 4 are subsequently carried out.

[0052] The processing from step S307 to step S309 in Fig. 5 is the same as the series of operations for the initial communication shown in Fig. 4, and therefore detailed description thereof will be omitted. The processing from step S311 in Fig. 5 is also the same as that in Fig. 4. In the example of Fig. 5, the processing from step S310 in Fig. 4 is unnecessary. The processing from step S312 to step S318 in Fig. 5 is the same as the series of operations for the initial communication shown in Fig. 4, and therefore detailed description thereof will be omitted.

[0053] The release request response collating unit 5D of the relay device 5 collates the content of the security release request for the destination floor received in step S318 with the content previously recorded in the release request response recording unit 5C (step S403). Specifically, it determines whether any of the above conditions (1) to (3) is satisfied. If any of conditions (1) to (3) is satisfied, the relay device 5 transfers the signal for the security release request for the destination floor directly to the elevator group control device 7 without relaying it through the security management device 3 (step S404). If the condition is not satisfied, the relay device 5 performs the processing of step S320 in the series of operations for the initial communication shown in FIG. 4, and subsequently performs the series of processing flows shown in FIG. 4.

[0054] The processing from step S323 to step S325 in Fig. 5 is the same as the series of operations for the initial communication shown in Fig. 4, and therefore detailed description thereof will be omitted. The processing from step S327 in Fig. 5 is also the same as that in Fig. 4. In the example of Fig. 5, the processing from step S326 in Fig. 4 is unnecessary. The processing from step S328 to step S333 in Fig. 5 is the same as the series of operations for the initial communication shown in Fig. 4, and therefore detailed description thereof will be omitted.

[0055] In this embodiment, the relay device 5 can forward requests from the robot server 2 to release security at the boarding floor and requests to release security at the destination floor to the security management device 3. In the elevator system of this embodiment, there is no need for direct cooperation or communication between the robot server 2 and the security management device 3. In this embodiment, for example, the robot manufacturer of the robot server 2 and the security manufacturer of the security management device 3 only need to consider and implement a function for cooperation and communication with the relay device 5. According to this embodiment, in an elevator system in which both the robot server 2 and the security management device 3 cooperate with the same elevator, the difficulty of implementation by users such as manufacturers can be reduced.

[0056] In this embodiment, the release request response recording unit 5C of the relay device 5 records the robot ID, the release request floor, and the time of reception of the request to release security at the boarding floor and the request to release security at the destination floor from the transmission unit 2A of the robot server 2. The release request response recording unit 5C of the relay device 5 also records the success or failure of the response to release security at the boarding floor and the response to release security at the destination floor from the transmission unit 7A of the elevator group control device 7, linking it to the request to release security at the boarding floor or the request to release security at the destination floor. The release request response collating unit 5D of the relay device 5 collates the security release request from the robot server 2 with past records, and if it matches predetermined conditions, i.e., if it is determined that security is ensured, it does not need to relay the request to the security management device 3. This makes it possible to reduce the possibility of delays caused by relaying communications as a system.

[0057] As described above, the release request response collating unit 5D of the relay device 5 in this embodiment collates the content of the security release request from the robot server 2 with the past communication records in the release request response recording unit 5C to determine whether predetermined conditions are met. Specifically, the determination is made based on three conditions: the robot ID that identifies the robot 1, the target floor of the security release request, and the time of receipt. This ensures the security of the system. Note that the condition determination may be made by determining whether all three conditions are met, with an emphasis on security, or by determining whether at least one condition is met, taking into account the ease of implementation and measures to prevent communication delays.
