[0005] Patent Document 1: Japanese Patent No. 6838684 Summary of the Invention

[0006] Anomalies in elevators also include low-reproducibility anomalies such as malfunctioning display on exterior equipment. Especially with low-reproducibility anomalies, operators require a significant amount of time to confirm their presence, placing a heavy burden on them. Furthermore, for example, in the inspection robot described in Patent Document 1, the status and movement of the object being inspected are checked by touching, tapping, or manipulating it. Such inspections struggle to detect low-reproducibility anomalies. Therefore, there is a need to develop a system capable of automatically inspecting the exterior equipment of elevators for anomalies.

[0007] The present invention was made in view of the above-mentioned problems, and provides an anomaly detection device and an anomaly detection system capable of automatically detecting anomalies in the exterior equipment of an elevator.

[0008] The anomaly determination device of the present invention collaborates with a robot to determine whether an elevator is malfunctioning. The elevator includes: an elevator control device that controls the movement of various parts of the elevator; an appearance device disposed in the car or at a landing, including at least one of an input unit and a display unit; and an appearance device control unit that controls the movement of the appearance device based on first received data obtained from receiving motion command data sent from the elevator control device. The robot has the following functions: detecting the movement state of the appearance device by a detection unit and generating motion state data representing the detected motion state; and acquiring first copied data as copied data of the first received data through communication with the appearance device control unit. The anomaly determination device includes: a data collection unit that collects motion state data and the first copied data; and a determination unit that determines whether the appearance device is malfunctioning by judging the matching between the collected motion state data and the first copied data.

Detailed Implementation

[0025] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Furthermore, in the drawings, identical or equivalent parts are labeled with the same reference numerals, and their descriptions are simplified or omitted.

[0026] Implementation Method 1

[0027] Figure 1 This is a schematic diagram illustrating the structure of the elevator system according to Embodiment 1. (As shown...) Figure 1 As shown, the anomaly detection system is applied to an elevator and installed in a building equipped with such an elevator. Examples of buildings include shopping malls, office buildings, and public facilities. The building has multiple floors, and the shaft 1 runs through all floors. Elevator stations 2 are located on each floor of the building. Multiple stations 2 are located opposite the shaft 1. The elevator includes a car 3 and a traction machine 4. The car 3 and the traction machine 4 are located inside the shaft 1. The traction machine 4 causes the car 3 to move up and down within the shaft 1.

[0028] The elevator is equipped with landing buttons 5, digital landing indicators 6, and a destination floor display (not shown) as external devices. These external devices are located at each landing 2. The landing buttons 5 function as landing input units, accepting and recording user commands such as calling the elevator. The digital landing indicators 6 function as landing display units, showing the position and direction of travel of the car 3. The destination floor display also functions as a landing display unit, showing the destination floor of the car 3.

[0029] Inside the car 3, as external equipment, there are a car control panel 8, a car analog indicator 9, a car digital indicator 10, and a car destination floor display 11. The car control panel 8 functions as a car input unit, accepting and registering input commands such as car calls from users in the car 3. The car control panel 8 includes car buttons for user operation. The car analog indicator 9, car digital indicator 10, and car destination floor display 11 each function as a car display unit. The car analog indicator 9 and car digital indicator 10 display the current car direction and the floor corresponding to the current position of the car 3, as well as other elevator status-related information. The car destination floor display 11 displays the car's destination floor. Furthermore, in the following text, unless otherwise specified, the car analog indicator 9 and car digital indicator 10 will be simply referred to as "car indicator".

[0030] There are no restrictions on the location where the communication device 12 can be installed. The communication device 12 can be installed in, for example, the hoistway 1, the elevator machine room, or the administrator's room. The communication device 12 includes a communication unit 12a.

[0031] The building control device 16 is installed in a building equipped with elevators. The building control device 16 is a control device for centralized control of various equipment installed throughout the building.

[0032] The location of the elevator control device 15 is not limited; for example, it can be installed within the hoistway 1. The elevator control device 15 controls the raising and lowering of the elevator car and monitors and controls the elevator's movements. Additionally, in Figure 1 The text only describes one elevator with one car, but the elevator control device 15 can also be a structure that controls multiple elevators.

[0033] The communication unit 12a is electrically connected to the elevator control device 15. The communication unit 12a is electrically connected to multiple landing controllers 7 via a landing transmission path 13 formed by landing transmission cables. Each landing controller 7 functions as a control unit for exterior devices. The landing controller 7 is electrically connected to the exterior devices on the landing side, which include landing buttons 5 and landing digital indicators 6. That is, each exterior device on the landing side is connected to the elevator control device 15 via the landing controller 7 and the communication unit 12a. The communication unit 12a, the elevator control device 15, the landing controller 7, and each exterior device on the landing side are connected, for example, in a manner that enables communication via UART (Universal Asynchronous Receiver Transmitter).

[0034] The communication unit 12a is electrically connected to the car controller 20 via the car transmission path 14, which is formed by the car transmission cable. The car controller 20 functions as a control unit for the exterior devices. The car controller 20 is electrically connected to the exterior devices on the car side, which include a car operation panel 8, a car analog indicator 9, a car digital indicator 10, and a car destination floor display 11. That is, each exterior device on the car side is connected to the elevator control device 15 via the car controller 20 and the communication unit 12a. The communication unit 12a, the elevator control device 15, the car controller 20, and the exterior devices on the car side can be connected, for example, in a manner that enables communication via UART.

[0035] The communication unit 12a is electrically connected to the building control device 16 via a transmission path 18 consisting of a transmission cable. The communication unit 12a and the building control device 16 are connected, for example, in a manner that enables communication via RS-422.

[0036] The anomaly detection system includes robot 17. Robot 17 is located inside the building. Robot 17 is capable of moving autonomously within the building and can board and alight from car 3.

[0037] Robot 17 is equipped with sensors such as optical sensors, a camera device, and a detection unit 17a. The detection unit 17a can acquire sensor detection data and image data captured by the camera device, and analyze the acquired data to detect the operational status of the external devices. Here, robot 17 is not limited to robots equipped with sensors and cameras. The anomaly detection system may, for example, be configured as a log for storage and playback, and can obtain data related to the operational status of each external device based on the log.

[0038] Robot 17 has a first communication interface. Robot 17 is configured to communicate bidirectionally with car controller 20 or landing controller 7 via wired or wireless means using the first communication interface. Specifically, robot 17 is connected to transmission path 21 via the first communication interface, thereby enabling communication with car controller 20, and connected to transmission path 22 via the first communication interface, thereby enabling communication with landing controller 7.

[0039] Furthermore, robot 17 has a second communication interface. Robot 17 is configured to communicate with communication unit 12a via the second communication interface and the building control device 16. Robot 17 sends a registration request for the target destination floor to communication unit 12a via the second communication interface and the building control device 16. Communication unit 12a transmits the received registration request for the target destination floor to elevator control device 15. Elevator control device 15 receives the registration request for the target destination floor. Thus, the destination floor registration performed by robot 17 is similar to a person pressing the destination floor button on the car operation panel 8.

[0040] The communication unit 12a can read the communication between the elevator control device 15 and the car operation panel 8 via the car transmission path 14. Therefore, the communication unit 12a can obtain information regarding whether each of the destination floor buttons on the car operation panel 8 within the car 3 has been pressed via serial transmission or the like. Specifically, when a user presses a destination floor button on the car operation panel 8, the communication unit 12a and the elevator control device 15 detect the button being pressed by the button being illuminated.

[0041] The elevator control unit 15 continuously transmits the acquired destination floor information to the car operation panel 8, the car analog indicator 9, the car digital indicator 10, and the car destination floor display 11 via the car transmission path 14. The communication unit 12a reads the communication between the elevator control unit 15 and the car operation panel 8 via the car transmission path 14, and obtains information related to all indicator codes of the car indicators through serial transmission or the like. The communication unit 12a checks the indicator codes and elevator management floor data based on the stored elevator management floor data, and thereby transmits the elevator management floor corresponding to the indicator code to the building control unit 16. The robot 17 receives the elevator management floor from the building control unit 16, converts the elevator management floor into a building management floor, and identifies the destination floor button and car position of the building management floor.

[0042] Based on the destination floor information received from the elevator control device 15, the car control panel 8 instructs the destination floor buttons to light up according to the physical connection sequence of the buttons, based on the lighting or extinguishing information from the lowest floor. As a result, the destination floor buttons are illuminated.

[0043] The car destination floor display 11 determines the elevator management floor whose destination floor button has been illuminated based on the destination floor information received from the elevator control device 15. The car destination floor display 11 uses floor list information to obtain the indicator code of the illuminated elevator management floor. The car destination floor display 11 displays the name of the floor corresponding to the obtained indicator code as the name of the destination floor on the screen. Then, the elevator control device 15 moves the car 3 towards the target floor. At this time, the elevator control device 15 continuously sends indicator codes corresponding to the current position of the car 3 to each indicator 9 and 10 of the car 3 via the car transmission path 14.

[0044] Robot 17 can identify when car 3 has reached the floor it needs to take based on the car's position information. Upon recognizing this, robot 17 sends a door-opening control command to communication unit 12a via building control device 16. Communication unit 12a transmits the door-opening control command to car control panel 8 via serial or parallel transmission. This enables robot 17 to perform door-opening control.

[0045] The communication unit 12a reads the communication between the elevator control device 15 and the car operation panel 8 via the car transmission path 14, and obtains information such as serial transmission whether the open or close door button on the car operation panel 8 inside the car 3 has been pressed. The communication unit 12a sends opening / closing information based on the obtained open / close door button information to the robot 17 via the building control device 16. The robot 17 confirms the open state of the car 3 based on the received door opening / closing information. Furthermore, the robot 17 can maintain the open state by issuing an open door control command for a predetermined time, and closes the car 3 by sending a close door instruction after the elevator ride is completed.

[0046] Figure 2 This diagram schematically illustrates an example of the hardware structure of the communication unit 12a of the communication device 12 in the anomaly detection system of this embodiment. (See diagram for reference.) Figure 2As shown, the communication unit 12a includes at least one ROM (Read-only Memory) 11b, one RAM (Random Access Memory) 11c, one EEPROM (Electrically Erasable Programmable Read-Only Memory) such as flash memory 11d, and one CPU (Central Processing Unit) 11e. Various programs are stored in the ROM 11b. Information required for operation, such as data for temporarily storing communication packets, is stored in the RAM 11c. The EEPROM 11d stores motion command data for playback, command response data, and robot analysis information. The CPU 11e communicates with the building control device 16 and the elevator control device 15 by executing the programs stored in the ROM 11b.

[0047] Figure 3 This is a diagram illustrating an example of a communication frame used to explain UART-based communication between communication device 12 and car controller 20, or UART-based communication between communication device 12 and landing controller 7. (See diagram for example.) Figure 3 As shown, a UART consists of a 1-bit start bit, 8-bit data bits, and a 1-bit stop bit. There are also cases where a 1-bit parity bit precedes the stop bit to detect data errors.

[0048] The uplink communication from the car controller 20 or the landing controller 7 to the communication device 12 and the downlink communication from the communication device 12 to the car controller 20 or the landing controller 7 are respectively... Figure 3 The data is transmitted as electrical signals in packet format. The 8-bit data bits consist of a command and corresponding data, and are always transmitted in the form of this UART.

[0049] Figure 4 This is a diagram illustrating an example of an RS-422-based communication frame between communication device 12 and building control device 16. For example, as... Figure 4 As shown, an RS-422-based communication frame consists of STX (indicating the start of the frame), LEN, data, BCC (for error detection), and ETX (indicating the end of the frame).

[0050] Figure 5This diagram illustrates an example of a communication frame between a building control device 16 and a robot 17. The building control device 16 and the robot 17 transmit / receive communication packets wirelessly. The communication packets are nested within frames from the next layer to the first layer. The header contains information such as the destination and transmission path for control data. The payload is the main data component of the packet, excluding the header and other additional information.

[0051] In the anomaly detection system of this embodiment, the communication device 12 functions as an anomaly detection device 25. As an anomaly detection device 25, the communication device 12 functions as a data collection unit 25a and a detection unit 25b. The data collection unit 25a collects data on motion commands sent / received between the elevator's various external devices and the robot 17. The detection unit 25b determines whether there are any anomalies in the elevator's various external devices and communications based on the collected data.

[0052] Figure 6 This is a diagram showing a summary of the various external devices of the elevator used in this embodiment, as well as the inspection data for communication checks. (See diagram below.) Figure 6 As shown, the inspection data includes the following data.

[0053] A. The retention value of the communication device 12 for sending / receiving motion command data between the elevator control device 15 and the landing controller or car controller.

[0054] B. Action command data sent / received between the elevator control device 15 and the external equipment on the car side or landing side.

[0055] C. The first copy data as the copy data of the motion command data of each transmission path obtained by robot 17.

[0056] D. Motion state data obtained by robot 17

[0057] E. Copy data of communication command data forwarded from robot 17 to the communication device

[0058] F. Results of the state analysis performed by robot 17

[0059] For example, the action command data for downlink communication in layer station transmission path 13 is Figure 6 The action command data for the uplink communication of the layer station transmission path, labeled 1, 1b, and 5, is as follows: Figure 6 Labels 2, 2b, and 7. The downlink communication operation command data for car transmission path 14 is... Figure 6 The action command data for the uplink communication of car transmission path 14, labeled 3, 3b, and 6, are as follows: Figure 6 The labels are 4, 4b, and 8.

[0060] Figure 6 The action command data consists of command and instruction data. These commands and instructions are directed to various external devices. These external devices include landing buttons 5 and digital landing indicators 6 (landing-side devices), and car-side devices such as the car control panel 8, car analog indicators 9, car digital indicators 10, and car destination floor display 11. An example of a command is "11" (lit up), and an example of instruction data is the indicator code "1" (000001).

[0061] Through the downlink communication of the floor transmission path 13, the elevator control device sends instruction transmission data as action command data to the floor controller 7. Figure 6 (1b) The floor controller 7 receives the instruction and sends data as the first received data. The floor controller 7 then processes the received first received data ( Figure 6 5) Control the appearance equipment on the floor side. The robot obtains the first copied data generated by copying the first received data via transmission path 22 and the first communication interface. Figure 6 Similarly, via the downward communication of the car transmission path 14, the elevator control device sends instruction transmission data as action instruction data to the car controller 20. Figure 6 (3b) The car controller 20 receives the instruction and sends data as the first received data. Figure 6 (6). The car controller 20 controls the exterior equipment on the car side based on the first received data. The robot obtains the first copied data generated by copying the first received data via the transmission path 21 and the first communication interface. Figure 6 (6c). Then, robot 17 transmits the first copy data to communication device 12 via transmission path 18 for cooperation between elevator system and robot 17. Figure 6 (10 and 11).

[0062] Through the uplink communication of the layer station transmission path 13, after receiving the first received data, the layer station controller 7 will send the instruction response data corresponding to the first received data ( Figure 6 2b) is sent to communication device 12. Communication device 12 receives instruction response data from floor controller 7 as second received data. Similarly, through the uplink communication of car transmission path 14, after receiving the first received data, car controller 20 sends instruction response data ( ) corresponding to the first received data. Figure 6 4b) is sent to the communication device 12. The communication device 12 receives the instruction response data from the car controller 20 as the second received data.

[0063] Furthermore, robot 17 uses its onboard sensors and cameras to acquire data such as detection values ​​or images corresponding to the actual movement status of each external device. This acquired data includes, for example, indicator information and button light status captured by robot 17's cameras. Robot 17 analyzes the acquired data corresponding to the actual movements and transmits the analysis results as movement status data to communication device 12 via transmission path 18. Figure 6 (9). The data transmitted to the communication device 12 is generated by codes arranged in sequence, such as indicator code "1" (000001) and indicator code "2" (000002).

[0064] Robot 17 checks data obtained from sensors, etc. Figure 6 9) and downlink communication command data ( Figure 6 The labels 5, 5c, 6, and 6c are checked to ensure consistency, i.e., whether each external device is operating according to the instructions. The inspection results are transmitted to the communication device 12 as comparison data to confirm the integrity of the transmission path 18. Figure 6 (12). Specifically, for example, if the indicator code of the instruction data is "1" (000001) and the indicator of the appearance device obtained by the robot 17 by the sensor or the like is off, the robot 17 notifies that an "abnormal" signal is present as the inspection result.

[0065] The communication device 12 has the following functions: collecting and analyzing the inspection data to check for any abnormalities. Specifically, as a first check, the communication device 12 verifies the integrity of the transmission of motion command data from the communication device 12 to the appearance device. Specifically, the communication device 12 compares the hold value of the motion command data ( Figure 6 (1 or 3) and the first copy of data transmitted from robot 17 ( Figure 6 The matching is determined by (10 or 11). If there is a discrepancy between the two, the integrity of the instruction transmission from the communication device 12 to each external device is questioned. This result helps to distinguish between errors caused by the floor transmission path 13 or car transmission path 14 between the elevator control device 15 and each external device, and errors caused by other factors.

[0066] As a second check, the communication device 12 is inspected for any malfunctions in the various external devices. Here, the first copy of the action command data obtained by the robot 17 and sent to the landing controller 7 or the car controller 20 is determined. Figure 6 (10 or 11) and the robot 17 use sensors and other means to obtain motion status data of each external device ( Figure 6Matching between 9) and 1. When the contents of the two are inconsistent, there is an error between the content of the action command received by each external device and the actual action of each external device relative to the action command, which helps to suspect whether there is a problem with the machine itself, i.e., with each external device.

[0067] As a third check, the communication device 12 determines the action command data sent to the communication device 12 from each external device. Figure 6 (2b or 4b) and the motion status data of each external device sent from robot 17 to communication device 12 ( Figure 6 The compatibility between (9) and (12) is verified to confirm the integrity of the instruction transmission from each external device to the communication device 12. In the event of inconsistency between the two, it helps to distinguish between errors caused by the transmission path between the elevator control device 15 and each design device and errors caused by other factors.

[0068] Finally, as the fourth check, a judgment is made. Figure 6 The analysis results of robot 12 are compared with the results of the first inspection to examine the transmission path 18 between robot 17 and communication device 12. Discrepancies between the two can help to question the integrity of the transmission path 18 between robot 17 and communication device 12.

[0069] If any abnormalities are found in the above inspection results, the communication device 12 will record the data acquired in sequence in the flash memory and notify the operator of the detected abnormality. This notification may be sent to a portable terminal carried by the operator, for example.

[0070] Figure 7 and Figure 8 This is a flowchart illustrating an example of the inspection control operation of the elevator system according to this embodiment. Figure 7 and Figure 8 The inspection shown includes determining whether there are any abnormalities in the communication between the visual equipment on the floor level and the visual equipment on the floor level.

[0071] Specifically, in Figure 7 In the example, in step S101, robot 17 moves to the designated floor station according to instructions from the building control device 16. Next, in step S102, robot 17 connects to the floor station controller 7 to communicate with it. That is, robot 17 connects its first interface to the transmission path 22. Robot 17 then replies to the communication device 12 with a notification indicating that the connection is complete.

[0072] Next, in step S103, the communication device 12 sends a signal to the robot 17 requesting the start of the inspection. When the robot 17 receives the instruction to start the inspection and becomes ready to begin the inspection, in step S104, the robot 17 sends a response to the communication device 12 indicating that it is ready to complete the inspection.

[0073] Next, in step S105, the communication device 12 causes the car 3 to move by transmitting floor call information for any floor to the car controller 20 as test data. Then, in step S106, the communication device 12 collects the uplink and downlink communication action command data of the floor transmission path 13 when the test data was transmitted, as well as the first copy data and action status data obtained by the robot 17.

[0074] In step S107, the communication device 12 determines the matching of the collected data with each other and checks whether there are any non-accidental differences in the content of each data that indicate anomalies.

[0075] In step S108, an abnormality is determined based on the inspection result of step S107. If no abnormality is found in step S108, the process proceeds to step S110 to determine whether a notification of inspection completion has been transmitted from communication device 12 to robot 17. If no notification of inspection completion has been transmitted, the process returns to S105 to continue the inspection.

[0076] In step S110, if it is determined that a notification of the end of the inspection has been transmitted, from Figure 7 A transferred to Figure 8 A, next, in Figure 8 In step S111, the communication device 12 records the timing data in the flash memory and transmits a normal notification to the operator. Then, the current processing is temporarily terminated.

[0077] On the other hand, if an abnormality is determined in step S108, from Figure 7 B transferred to Figure 8 Next, let's move on to B. Figure 8 Step S120. In step S120, the inspection completion notification is sent from the communication device 12 to the robot 17.

[0078] Next, in step S121, the communication device 12 records the acquired timing data in the flash memory. Furthermore, the communication device 12 sends a signal notifying the operator of the abnormal situation.

[0079] Next, in step S122, the communication device 12 checks whether the abnormal state is a continuous phenomenon or an instantaneous phenomenon based on the acquired inspection data. Based on the inspection result, in step S123, it is determined whether the abnormal state is a continuous phenomenon. If it is determined in step S123 that the abnormal state is not a continuous phenomenon, the current processing ends.

[0080] On the other hand, if it is determined in step S123 that the phenomenon is continuous, then in step S124, the communication device 12 extracts the timing data of the state before the anomaly occurred from the timing data, retransmits the action command data in the timing data, and attempts to automatically recover.

[0081] In step S125, it is determined whether the exception has been eliminated through retransmission. If it is determined in step S125 that the exception has been eliminated, the current process ends directly. On the other hand, if it is determined in step S125 that the exception has not been eliminated, in step S126, it is determined whether a predetermined number of retransmissions and retries have been performed. Specifically, it is determined whether counter i has exceeded a predetermined number. Counter i is a counter that counts the number of repetitions of the processing in steps S124 to S125.

[0082] If it is determined in step S126 that the prescribed number of retransmission retries has not been performed, the counter i is incremented in step S127, and the process returns to step S124 to attempt automatic recovery again. On the other hand, if it is determined in step S126 that the prescribed number of retransmission retries has been performed, the communication device 12 notifies the operator in step S128 that automatic recovery is not possible, and the current process is temporarily terminated.

[0083] Figure 9 as well as Figure 10 This is a flowchart illustrating an example of the communication check control operation between the car-side appearance device and the car-side appearance device of the elevator in this embodiment. Figure 9 as well as Figure 10 The inspection shown includes determining whether there are any abnormalities in the communication between the car-side appearance equipment and the car-side appearance equipment.

[0084] Figure 9 as well as Figure 10 The process shown replaces steps S101-S106 with steps S131-S136, except that it includes the "no" determination in steps S111 and S123, the "yes" determination in step S125, or the step S140 following step S128. Figure 7 as well as Figure 8 The control actions are the same. The processing in steps S107 to S128 is the same as in... Figure 7 as well as Figure 8 The processing described in the previous section is the same, so the explanation is omitted.

[0085] like Figure 9 As shown, in step S131, firstly, robot 17 moves into car 3 according to instructions from building control device 16. Next, in step S132, robot 17 connects to car controller 20 to communicate with it. That is, robot 17's first interface connects to transmission path 22. When the connection is complete, robot 17 sends a notification indicating connection completion to communication device 12.

[0086] Next, in step S133, the communication device 12 sends a signal to the robot 17 requesting the start of the inspection. When the robot 17 receives the instruction to start the inspection and becomes ready to begin the inspection, in step S134, it sends a response to the communication device 12 indicating that it has completed preparations for the start of the inspection.

[0087] Next, in step S135, the communication device 12 causes the car 3 to move by transmitting a call for the car's destination to any floor to the car controller 20. Then, in step S136, the communication device 12 collects the motion command data for the upward and downward communication of the car transmission path 14, the motion status data obtained by the robot 17, and the first copy data.

[0088] Then, as Figure 10 As shown, after the "No" determination in step S111, step S123, the "Yes" determination in step S125, or the processing in step S128, in step S140, robot 17 descends from car 3. Then, the current process ends.

[0089] As described above, the anomaly determination device 25 of this embodiment includes: a data collection unit 25a, which collects first copy data of motion state data obtained by the robot 17 and motion command data sent from the elevator control device; and a determination unit 25b, which determines whether there is an anomaly in the appearance equipment by judging the matching between the collected motion state data and the first copy data. Therefore, for defects with very low reproducibility, operators no longer need to monitor them closely to determine whether there is an anomaly in the appearance equipment.

[0090] Furthermore, the data collection unit 25a of the anomaly determination device 25 in this embodiment also collects motion command data sent from the elevator control device 15. The determination unit 25b further determines whether there is an anomaly in the communication between the elevator control device 15 and the appearance equipment control unit by judging the matching between the collected first copy data and the motion command data. Therefore, for defects with very low reproducibility, operators no longer need to monitor them closely, and can distinguish between the integrity of the communication between the elevator control device 15 and the appearance equipment control unit and whether there is an anomaly in the appearance equipment for determination.

[0091] Furthermore, in this embodiment, the elevator includes a communication device 12, which mediates and coordinates the communication between the elevator control device 15 and the appearance equipment control unit. After receiving the first received data, the appearance equipment control unit of the anomaly determination device 25 sends instruction response data corresponding to the first received data to the elevator control device 15. The data collection unit 25a further collects second received data, which is the instruction response data sent from the appearance equipment control unit, received by the communication device 15. The determination unit 25b further determines whether there is an anomaly in the communication between the appearance equipment control unit and the communication device by judging the matching between the collected operation status data and the second received data. Therefore, for defects with very low reproducibility, operators no longer need to monitor them closely; they can distinguish between the integrity of the communication between the appearance equipment control unit and the communication device and the presence of anomalies in the appearance equipment for determination.

[0092] Implementation Method 2

[0093] Figure 11 This is a diagram schematically showing the overall structure of the elevator system according to Embodiment 2. Figure 11 In addition to having a monitoring panel 30, the elevator system also has the following features: Figure 1 The elevator system has the same structure. Specifically, Figure 11 The elevator system is equipped with a monitoring panel of 30. Figure 1 Transmission path 18 is a dedicated transmission path between the building control device 16 and the communication device 12. In contrast, in... Figure 11 In this structure, transmission path 18 is used not only for transmission between communication device 12 and building control device 16, but also for transmission between monitoring panel 30 and building control device 16. That is, monitoring panel 30 shares transmission path 18 between building control device 16 and elevator control device 15. Therefore, building control device 16 can act as monitoring panel 30 and send / receive information such as car 3 position, various operating lights, and various operating switches transmitted by monitoring panel 30 between it and elevator control device 15.

[0094] Figure 12This is a flowchart illustrating the control actions performed by robot 17 to confirm operational checks. Figure 12 In the control procedure shown for confirming the operation check, firstly, in step S201, robot 17 moves into car 3. Next, in step S202, robot 17 connects to car controller 20 to communicate with it. That is, robot 17's first communication interface is connected to transmission path 21. When the connection is complete, robot 17 sends a notification indicating the connection is complete to communication device 12.

[0095] Next, in step S203, the communication device 12 sends a signal to the robot requesting the start of the inspection. In step S204, the robot 17 replies to the communication device 12 with a response indicating that it is ready to start the inspection.

[0096] In step S205, robot 17, posing as monitoring panel 30, transmits a packet via communication device 12 from transmission path 18 to elevator control device 15, indicating that the control operation switch is turned on. In step S206, elevator control device 15 receives the packet and switches to the control operation mode, initiating control operation.

[0097] In step S207, robot 17 uses sensors and cameras to obtain the display of the control operation of various external devices, as well as the changes in the car's position, the door opening and closing status, the car lighting status, and the actual operation status of the door opening and closing button lights. It analyzes these data to generate action status data. Robot 17 then transmits the action status data to communication device 12 via transmission path 18.

[0098] In step S208, robot 17 receives a copy of the downlink communication data from car controller 20 via transmission path 21 from car controller 20. This allows it to obtain the display of control operation on the indicator and changes in car position. Similarly, robot 17 obtains a first copy of the action command data from uplink communication on car transmission path 14 from car controller 20. This allows it to obtain states such as door open / close status, car lighting status, and the status of door open / close button lights. Robot 17 then notifies communication device 12 of the obtained results via transmission path 18.

[0099] In step S209, the communication device 12 receives the data sent from the robot 17 in steps S207 and S208.

[0100] Then, in step S210, the communication device 12 receives action command data from the monitoring panel 30, which includes information on the car position and the control operation lights.

[0101] In step S211, the communication device 12 checks whether the control operation has been correctly implemented by judging the matching between the data obtained in steps S209 and S210. If it is determined that the operation has been correctly implemented, the operator is notified in step S212 that there is no problem. On the other hand, if it is determined in step S211 that the operation has not been correctly implemented, the operator is notified that there is a problem.

[0102] Furthermore, in this embodiment, the controlled operation is taken as an example, but as long as the operation switch can be notified from the monitoring panel 30 to the elevator control device 15, the same inspection can be carried out for other operations.

[0103] Other implementation methods

[0104] In the above embodiments 1 and 2, the display of the inspection indicator was described. However, as long as the device transmits the action command through communication, the same inspection can be performed on other devices besides the aforementioned appearance device.

[0105] Furthermore, in the above-described embodiments 1 and 2, the communication device 12 was described as having both a data acquisition unit and a determination unit, and was used to determine whether there were any abnormalities in the elevator system's equipment and communication. The communication device 12 relays communication between the elevator control device 15 and each device, and between the elevator control device 15 and the building control device 16, and can easily acquire the action command data transmitted by the communication device 12. However, the functions of the data acquisition unit and the determination unit, as part of the elevator system's abnormality determination system, are not limited to those of the communication device 12, and may also be functions of other devices. Furthermore, the functions of the data acquisition unit and the determination unit may also be configured to be provided by a server located in the cloud or similar environment.

[0106] Furthermore, in the anomaly determination of Embodiments 1 and 2, the method of determining whether there is an anomaly in the elevator system is described by judging the matching between the action command data sent from the elevator control device 15 to the landing controller 7 or the car controller 20 and the corresponding first copy data and action status data. However, the data used for anomalies in the elevator system is not limited to this, and may also have the following structure: in response to the action command sent from the communication device 12 to the car controller 20 or the landing controller 7, the presence or absence of an anomaly is determined based on the command response data sent from the car controller 20 or the landing controller 7 to the communication device 12, and the second copy data, which is a copy of the command response data obtained by the robot 17, and the action status data.

[0107] Furthermore, the elevator system's anomaly detection system can also have a structure with an inspection playback mode. In this mode, timing data acquired and stored in flash memory through the inspection control in Embodiments 1 and 2 is effectively utilized to generate test data instead of the action command data used for inspection, and inspection is performed. In this case, the communication device 12 has an input section for inputting test data. When the operator sets this mode, the input section of the communication device 12 transmits the test data as action command data to the car controller 20 or the landing controller 7, and acquires timing data as a response from the car controller 20 or the landing controller 7 to the communication device 12. Since the acquired timing data should be consistent with the response data in the flash memory, normal and abnormal conditions can also be inspected. According to the inspection in the inspection playback mode, inspection can be performed without going through the elevator control device 15, and therefore, reproduction tests can be performed without moving the elevator.

[0108] Furthermore, the anomaly determination device of Embodiment 1 or Embodiment 2 may also include a storage unit storing a first learned model for determining whether the appearance equipment has an anomaly. The determination unit 25b uses the first learned model stored in the storage unit to determine whether the appearance equipment has an anomaly. In this case, the first learned model can be configured to be pre-generated by learning known matching motion state data and first copy data. The determination unit 25b uses the first learned model to determine whether the appearance equipment has an anomaly based on the motion state data and first copy data collected by the data collection unit 25a during elevator inspection. Furthermore, the anomaly determination device of Embodiment 1 or Embodiment 2 may also include a first model generation unit that generates the first learned model by learning known matching motion state data and first copy data.

[0109] Furthermore, the anomaly determination device of Embodiment 1 or Embodiment 2 may also include a storage unit storing a second learned model for determining whether there is an anomaly in the communication between the elevator control device and the appearance device control unit. The determination unit 25b uses the second learned model stored in the storage unit to determine whether there is an anomaly in the communication between the elevator control device and the appearance device control unit. In this case, the second learned model can be pre-generated by learning first copied data and motion command data with known matching. The determination unit 25b uses the second learned model to determine whether there is an anomaly in the communication between the elevator control device and the appearance device control unit based on the first copied data and motion command data collected by the data collection unit 25a during elevator inspection. In this case, the motion command data may be motion command data sent from the elevator control device or motion command data for inspection sent from the communication device. Furthermore, the anomaly determination device of Embodiment 1 or Embodiment 2 may also include a second model generation unit that generates the second learned model by learning first copied data and motion command data with known matching.

[0110] Furthermore, the anomaly determination device of Embodiment 1 or Embodiment 2 may also include a storage unit storing a third learned model for determining whether there is an anomaly in the communication between the appearance equipment control unit and the communication device. The determination unit 25b uses the third learned model stored in the storage unit to determine whether there is an anomaly in the communication between the appearance equipment control unit and the communication device. In this case, the third learned model can be configured to be pre-generated by learning known matching motion state data and second received data (data obtained by the communication device from receiving instruction response data sent from the appearance equipment control unit). The determination unit 25b uses the third learned model to determine whether there is an anomaly in the communication between the appearance equipment control unit and the communication device based on the motion state data and second received data collected by the data collection unit 25a during elevator inspection. Furthermore, the anomaly determination device of Embodiment 1 or Embodiment 2 may also include a third model generation unit that generates the third learned model by learning known matching motion state data and second received data.
