Hereinafter, the configurations of the monitoring device 8 and the management server 10, which constitute the maintenance management system 100, will be described in more detail with reference to FIG. 1 as well.

2. Configuration of Monitoring Apparatus 8 FIG. 2 is a block diagram for explaining an example of the configuration of the monitoring apparatus. The monitoring device 8 includes a control device 20 and an in-car communication device 22 . The controller 20 comprises a processor 201 and a memory 202 coupled with the processor 201 . Memory 202 stores one or more programs 203 executable by processor 201 and various data 204 associated therewith. Various processes by the processor 201 are realized by the processor 201 executing the program 203 . The program 203 includes, for example, an elevator monitoring program, which will be described later.

The monitoring device 8 receives monitoring data transmitted from the control panel 6 . The monitoring data is, for example, operation data or call data of equipment to be controlled in an elevator. Operational data includes, for example, driving conditions, door opening/closing conditions, car load, or car position. Call data includes, for example, elevator call registration, call assignment, or call response data. The acquired monitoring data is stored in the memory 202 .

Also, the monitoring device 8 comprehensively monitors the state of the elevator based on the monitoring data. Typically, the processor 201 of the monitoring device 8 constantly monitors the operation of the elevator for signs of failure by executing a monitoring program included in the program 203 . This process is hereinafter referred to as "monitoring process". As a result of the monitoring process, if a failure symptom is included, the processor 201 stores a notification corresponding to the failure symptom in the memory 202 as a trigger notification and transmits it to the management server 10 .

The in-car communication device 22 is installed on an in-car operating panel (not shown) inside the car 1 . The in-car communication device 22 is a voice communication device having a microphone and a speaker. The processor 201 of the monitoring device 8 performs voice communication between the in-car communication device 22 and the management server 10 by executing the communication program included in the program 203 . This process is hereinafter referred to as "call processing". Typically, in call processing, a voice signal input from the in-car communication device 22 is transmitted to the management server 10 via the network 9, and a voice signal received from the management server 10 via the network 9 is sent to the car. Output from the communication device 22 .

4. Configuration of Management Server 10 The management server 10 is a device for performing maintenance and management of elevators based on monitoring data transmitted from the monitoring device 8 . FIG. 3 is a block diagram showing an example of the configuration of the management server 10. As shown in FIG.

The management server 10 is one computer or a collection of multiple computers connected by a communication network. Management server 10 comprises one or more processors 30 and one or more server memories 32 coupled to processors 30 . Server memory 32 stores one or more programs 321 executable by processor 30 and various data 322 associated therewith. Data 322 includes a maintenance database 323 for identifying elevator failure symptom factors. In other words, the maintenance database 323 is a database in which trigger notifications are associated with elevator failure symptom factors.

Various processes by the processor 30 are realized by the processor 30 executing the program 321 . FIG. 4 is a functional block diagram showing functions realized by the processor 30 of the management server 10 executing programs. As shown in FIG. 4 , the processor 30 includes a generation processing section 302 , a transmission processing section 304 , a reception processing section 306 and a determination processing section 308 .

The generation processing unit 302 generates a confirmation message for confirming the failure symptom factor occurring in the elevator with the crew in the car 1 of the elevator based on the trigger notification received from the monitoring device 8 and the response message described later. This process is hereinafter referred to as "generation process". Examples of failure indication factors here include improper opening and closing of elevator doors, defective buttons, and defective lighting.

The door opening/closing failure is a failure in which the door of the elevator car 1 does not completely close or does not open completely. Door opening/closing failures are caused not only by failure of the equipment, but also by foreign matter being caught in the door, or by pressing the door by a passenger carrying luggage. The button failure includes a failure in which a button such as a destination floor button is kept pressed or does not respond even when pressed. Illumination failures include failures such as burnout or flickering of light bulbs in the car 1 .

The maintenance database 323 stores confirmation messages corresponding to failure symptom factors. In the generation process, the generation processing unit 302 refers to the maintenance database 323 and generates a confirmation message corresponding to the failure symptom factor.

The transmission processing unit 304 transmits the generated confirmation message to the occupants in the car 1 . This process is hereinafter referred to as "send process". In the transmission process, the transmission processing unit 304 transmits a confirmation message to the monitoring device 8 . The monitoring device 8 outputs a confirmation message from the in-car communication device 22 through call processing.

When the passenger who has heard the confirmation message uses the in-car communication device 22 to utter a response message, the monitoring device 8 transmits the response message to the management server 10 via the network 9 . The reception processing unit 306 receives a response message from the monitoring device 8 via the network 9 . This process is hereinafter referred to as "reception process". The received response message is used for generation processing and determination processing, which will be described later.

Based on the response message, the determination processing unit 308 determines whether maintenance personnel should be dispatched to the site. This process is hereinafter referred to as "determination process". In the determination process, the determination processing unit 308 recognizes the content of the response message by a known voice recognition function. The content of the speech recognition function here is not limited. The determination processing unit 308 identifies specific failure symptom factors based on the recognition result of the recognized response message and the content of the trigger notification. Then, the determination processing unit 308 determines whether maintenance personnel should be dispatched to the site based on the identified failure symptom factors.

5. Specific Processing Executed in Maintenance Management System of Embodiment The flow of processing executed by the maintenance management system 100 according to the embodiment will be described with reference to FIGS. 5 and 6. FIG.

FIG. 5 is a flow chart showing a control routine of monitoring processing executed by the maintenance management system according to the first embodiment. The routine shown in FIG. 5 is a routine repeatedly executed by the processor 201 of the monitoring device 8. FIG.

In step S100 of the routine shown in FIG. 5, the processor 201 receives monitoring data transmitted from the control panel 6. The received monitoring data is stored in memory 202 . At the next step S102, the processor 201 monitors whether the operation of the elevator includes fault indications by executing the monitoring program contained in the program 203. FIG. As a result, if no failure symptom is included, this routine is terminated. On the other hand, if the operation of the elevator includes a symptom of failure, the process proceeds to step S104. At step S<b>104 , the processor 201 generates a trigger notification and transmits it to the management server 10 .

6 is a flow chart showing a control routine of processing executed by the maintenance management system according to Embodiment 1. FIG. The routine shown in this figure is a routine repeatedly executed by the processor 30 of the management server 10 .

At step S<b>112 , processor 30 determines whether a trigger notification has been received from monitoring device 8 . As a result, if the trigger notification has not been received, this routine is terminated.

On the other hand, in step S112, when the trigger notification is received, the process proceeds to step S114. At step S114, processor 30 sends a confirmation message to the occupants in car one. Here, processor 30 generates a confirmation message corresponding to the trigger notification in generation processing section 302 . For example, if the trigger notification includes a failure symptom of door opening/closing failure, the generation processing unit 302 first generates a confirmation message such as "This is the information center. Is there anyone in the car?" The processor 30 transmits the generated confirmation message to the monitoring device 8 via the network 9 in the transmission processing unit 304 . When the process of step S114 is completed, the process proceeds to step S116.

The monitoring device 8 voice-transmits the confirmation message received from the in-car communication device 22 . When the passenger who has heard the confirmation message speaks a response message using the in-car communication device 22 , the monitoring device 8 transmits the response message to the monitoring device 8 via the network 9 .

In step S116, processor 30 determines whether reception processing unit 306 has received a response message from a passenger. As a result, when the response message has not been received, the process of step S116 is repeatedly executed. On the other hand, if a response message has been received, the process proceeds to step S118.

In step S118, the processor 30, in the judgment processing unit 308, judges whether or not the response message has been received and the failure symptom factor has been identified. Here, the processor 30 recognizes the contents of the received response message using the speech recognition function. The processor 30 then determines whether or not a specific failure symptom factor has been identified by the response message. In one example, if the response message is "I'm holding the door so it doesn't close when the package is being brought in."

In another example, if the response message is "There seems to be something wrong with the opening and closing of the elevator door.", and if the concrete failure symptom factor cannot be specified only by the content of the response message, the process proceeds to step S122. . In step S122, processor 30 determines whether or not the confirmation message has been repeated a specified number of times in determination processing section 308 . The specified number of times here is the upper limit number of confirmation messages that are sent to identify the failure symptom factor. In step S122, if it is determined that the confirmation message has been repeated the specified number of times, it is determined that the failure symptom factor cannot be identified, and the process proceeds to step S124. On the other hand, if the confirmation message has not been repeated the specified number of times, it is determined that there is another confirmation message for identifying the cause of failure symptoms, and the process proceeds to step S114 again. Then, the processor 30 receives the response message received in step S116 and generates a confirmation message for further narrowing down the failure symptom factors in the generation processing unit 302 . In one example, the generation processing unit 302 generates a confirmation message such as "Is something stuck in the door?"

As a result, in step S116, if a response message stating, for example, "It seems that something has been removed and the object has recovered" is received, the process proceeds to step S118, and the obstruction of the object whose failure symptom factor has already been resolved is received. identified as having been In another example, when the response message "Something still seems to be wrong" is received, the process proceeds to step S118, and the failure symptom factor is identified as the equipment failure. In step S118, if the failure symptom factor could be identified from the content of the response message, the process proceeds to step S120, and if the failure symptom factor could not yet be identified, the process proceeds to step S122 again. In this way, the processing from step S114 to step S118 and step 122 are repeatedly executed until a failure symptom factor is identified in step S118 or the confirmation message is repeated a specified number of times in step S122.

In step S120, the processor 30 causes the determination processing unit 308 to determine whether maintenance personnel should be dispatched based on the failure symptom factor identified in step S118. For example, when it is determined in the process of step S118 that the failure symptom factor is due to manual work, the determination processing unit 308 determines that dispatch of maintenance personnel is unnecessary, and proceeds to step S126. Alternatively, in the process of step S118, if it is determined that the failure symptom factor is already solved, the object being caught, the determination processing unit 308 determines that it is unnecessary to dispatch maintenance personnel, and proceeds to step S126. Alternatively, if it is determined in the process of step S118 that the failure symptom factor is the failure of the equipment, it is determined that dispatch of maintenance personnel is necessary, and the process proceeds to step S124.

In step S124, the processor 30 requests dispatch of maintenance personnel. Further, in step S124, the generation processing unit 302 generates a message to the crew to the effect that maintenance personnel are requested to be dispatched.

In step S<b>126 , the processor 30 registers the determination result information including the failure symptom factors in the server memory 32 without requesting the dispatch of maintenance personnel. This process is called "registration process". Further, in step S126, the generation processing unit 302 generates a message to the crew to the effect that dispatch of maintenance personnel is not requested.

According to such a maintenance management system 100, the following effects are obtained.

Many of the situations in which trigger notifications are generated include failure symptoms due to poor handling of elevator equipment in the field. According to the maintenance management system 100, by having the occupants in the car 1 confirm specific failure symptom factors, it is possible to determine whether or not maintenance personnel need to be dispatched. As a result, unnecessary dispatch of maintenance personnel can be reduced.

According to the maintenance management system 100, the determination result information including the trigger notification and failure symptom factor is registered when the request for dispatch of maintenance personnel is not made. This makes it possible to later refer to the detailed situation when a failure symptom occurs, so that this information can be used for analysis of failure symptom factors and the like.

6. Modifications The maintenance management system 100 of the present disclosure can adopt the following modifications.

An occupant in car 1 may desire passage to an information center operator. Therefore, the in-car operation panel in the car 1 may be provided with an interphone button that is pressed when directly talking to the operator. In such a case, a label that reads, "Press the intercom button to talk to the operator," can be pasted next to the intercom button.

The passenger's response message is not limited to voice input. That is, the response message may be input from a display device such as a touch panel provided in the car 1, or may be input using buttons on the in-car operating panel.

Among the failure symptom factors of the trigger notification, there are factors that are difficult for the occupant in the car 1 to visually confirm. Therefore, the maintenance management system 100 may determine whether or not to send a confirmation message of the failure symptom factor to the occupants in the car 1 when the management server 10 receives the trigger notification. In this case, the maintenance management system 100 stores in the maintenance database 323, for example, a list of failure symptom factors that can be confirmed by the crew, and refers to the list to determine whether or not to send a confirmation message to the crew. do it.

FIG. 7 is a diagram showing a modification of the hardware resources of the management server 10. As shown in FIG. In the example shown in FIG. 7, the management server 10 comprises processing circuitry 34 including, for example, a processor 30 , server memory 32 and dedicated hardware 33 . FIG. 7 shows an example in which some of the functions of the management server 10 are implemented by dedicated hardware 33. As shown in FIG. All the functions of the management server 10 may be realized by dedicated hardware 33 . Dedicated hardware 33 can be a single circuit, multiple circuits, programmed processors, parallel programmed processors, ASICs, FPGAs, or combinations thereof.

Features of maintenance management system according to the second embodiment In the maintenance management system 100 according to the second embodiment, when the monitoring device 8 determines that the monitoring data includes a symptom of failure, the monitoring device 8 notifies the occupants in the car. Then, the failure symptom factors are checked, and it is determined whether or not to send the trigger notification. The flow of processing executed by the maintenance management system 100 according to the embodiment will be described below with reference to the flowchart of FIG.

FIG. 8 is a flow chart showing a control routine of processing executed by the maintenance management system according to the second embodiment. The routine shown in FIG. 8 is repeatedly executed by the processor 201 of the monitoring device 8 . In steps S202 and S204 of FIG. 8, the processor 201 performs the same processing as steps S102 and S104 of the routine shown in FIG. If it is determined in step S204 that confirmation of failure symptom factors by the occupant is necessary, the process proceeds to step S206.

At steps S206, S208, S210, 212, and S214, the processor 201 executes the same processing as the processing executed by the processor 30 of the management server 10 at steps S114, S116, S118, S120, and S122 of the routine shown in FIG. do.

In the process of step S212, if it is determined that dispatch of maintenance personnel is necessary, the process proceeds to step S216, and if it is determined that dispatch of maintenance personnel is unnecessary, this routine ends. At step S<b>216 , the processor 201 transmits the trigger notification to the management server 10 . The management server 10 that received the trigger notification requests dispatch of maintenance personnel.

According to the control as described above, the monitoring device 8 can allow the occupant in the car 1 to confirm the failure symptom factor. As a result, it is possible to transmit the trigger notification in a situation where maintenance personnel need to be dispatched, so that unnecessary dispatch of maintenance personnel can be reduced.
