Description

maintenance management system

This disclosure relates to a maintenance management system, and in particular, to a maintenance management system that determines whether a maintenance worker needs to be dispatched for signs of an elevator malfunction.

Patent Document 1 discloses a technique for rescuing passengers when they are trapped in an elevator car. In this technology, when a passenger is trapped in an elevator car by emergency stopping the car due to some abnormality, the passenger is rescued by a command from a remote monitoring center that communicates with the elevator.

Japanese Patent Application Publication No. 2006-44930

The elevator monitoring device constantly monitors the elevator for any signs of malfunction. If the elevator shows signs of malfunction, the monitoring device may send a notification, called a trigger notification, to a remote information center. The information center that received the trigger notification dispatches a maintenance worker to the scene and responds to the malfunction.

However, the trigger notification may include factors other than a failure, such as a passenger pressing an elevator car door. In cases like this, dispatching a maintenance worker to the scene is not necessarily the best decision.

The purpose of this disclosure is to provide a maintenance management system that can suppress unnecessary dispatch of maintenance workers in response to signs of elevator failure.

The present disclosure applies to a maintenance management system including a monitoring device that monitors an elevator based on elevator monitoring data, and a management server connected to the monitoring device and a network. The monitoring device is configured to transmit a trigger notification, which is a notification corresponding to the failure symptom of the elevator, to the management server when the monitoring data includes a failure symptom of the elevator. The management server has a server memory storing a maintenance database containing information for specifying failure symptom factors corresponding to the trigger notification, and a processor coupled to the server memory. When the processor receives a trigger notification from the monitoring device, the processor uses the trigger notification and the maintenance database to generate a confirmation message to confirm the cause of the failure symptom for the passenger of the elevator, and to transmit the confirmation message to the passenger. It is configured to execute a transmission process, a reception process for receiving the passenger's response message to the confirmation message, and a judgment process for determining whether a maintenance worker needs to be dispatched to the scene based on the response message.

Additionally, the present disclosure applies to a maintenance management system including a monitoring device that monitors an elevator based on elevator monitoring data, and a management server connected to the monitoring device through a network. The management server is configured to request dispatch of a maintenance worker to the site when a trigger notification, which is a notification corresponding to a failure symptom of the elevator, is received from the monitoring device. When the monitoring data includes a failure symptom, the monitoring device includes processing to generate a confirmation message for confirming the cause of the failure symptom for the passenger of the elevator, processing to transmit the confirmation message to the passenger of the elevator, and processing to send the confirmation message to the passenger of the elevator. Processing of receiving a response message from a passenger, processing of determining whether dispatch of a maintenance worker to the scene is necessary based on the response message, and sending a trigger notification to the management server when it is determined that dispatch of a maintenance worker is necessary. It is configured to execute processing.

According to the maintenance management system of the present disclosure, failure symptom factors are confirmed by elevator passengers. This makes it possible to suppress unnecessary dispatch of maintenance personnel in response to signs of elevator malfunction.

Embodiment.

1. Configuration of the elevator of the embodiment

1 is a diagram showing an example of an elevator to which a maintenance management system is applied. The elevator is equipped with an elevator car (1) and a counterweight (2). The elevator car (1) moves up and down the hoistway (3). The counterweight (2) moves up and down the hoistway (3). The hoistway 3 is a space extending up and down formed in a building. The elevator car (1) and counterweight (2) are suspended from the hoistway (3) by a rope (4). In Figure 1, a 1:1 roping type elevator device is shown as an example.

The rope (4) is wound around the hoisting machine (5) and hung. The elevator car (1) is driven by a hoisting machine (5). The control panel (6) controls the hoisting machine (5). That is, the movement of the elevator car 1 is controlled by the control panel 6. FIG. 1 shows an example in which the hoisting machine 5 and the control panel 6 are provided in the machine room 7 above the hoistway 3. The hoisting machine 5 and the control panel 6 may be provided in the hoistway 3. The hoisting machine 5 may be provided at the top of the hoistway 3 or may be provided in a pit of the hoistway 3.

The monitoring device 8 is connected to the control panel 6. The monitoring device 8 communicates with external devices through the network 9. The management server 10 is included in the external device. As an example, the management server 10 is provided in a remote information center that manages the elevator.

The maintenance management system 100 of this embodiment is configured to include a monitoring device 8 and a management server 10. Hereinafter, with reference to FIG. 1 as well, the configuration of the monitoring device 8 and the management server 10 that constitute the maintenance management system 100 will be described in more detail.

2. Configuration of the monitoring device (8)

Figure 2 is a block diagram for explaining an example of the configuration of a monitoring device. The monitoring device 8 includes a control device 20 and a call device 22 in the elevator car. The control device 20 includes a processor 201 and a memory 202 coupled to the processor 201. The memory 202 stores one or more programs 203 that can be executed by the processor 201 and various data 204 related thereto. When the processor 201 executes the program 203, various processes by the processor 201 are realized. The program 203 includes, for example, an elevator monitoring program described later.

The monitoring device 8 receives monitoring data transmitted from the control panel 6. Monitoring data is, for example, operation data or call data of an elevator control target device. Operational data includes, for example, driving status, door open/closed status, elevator car load, or elevator car position. Call data includes, for example, data of elevator call registration, call assignment, or response to a call. The acquired monitoring data is stored in memory 202.

Additionally, the monitoring device 8 comprehensively monitors the status of the elevator based on monitoring data. Typically, the processor 201 of the monitoring device 8 constantly monitors whether the operation of the elevator contains any signs of failure by executing the monitoring program included in the program 203. This processing is hereinafter referred to as “monitoring processing.” If a failure symptom is included as a result of the monitoring process, the processor 201 stores a notification corresponding to the failure symptom as a trigger notification in the memory 202 and transmits it to the management server 10.

The call device 22 in the elevator car is installed on an operation panel in the car 1, not shown. The call device 22 in the elevator car is a voice call device equipped with a microphone and a speaker. The processor 201 of the monitoring device 8 performs a voice call between the call device 22 in the elevator car and the management server 10 by executing a call program included in the program 203. This processing is hereinafter referred to as “call processing.” Typically, in call processing, a voice signal input from the call device 22 in the elevator car is transmitted to the management server 10 through the network 9, and the network 9 is transmitted from the management server 10. The voice signal received through the elevator car is output from the call device 22 in the elevator car.

4. Configuration of the management server (10)

The management server 10 is a device for performing maintenance management of the elevator based on monitoring data transmitted from the monitoring device 8. Figure 3 is a block diagram showing an example of the configuration of the management server 10.

The management server 10 is one computer or a collection of multiple computers connected through a communication network. The management server 10 includes one or more processors 30 and one or more server memories 32 coupled to the processors 30 . The server memory 32 stores one or more programs 321 that can be executed by the processor 30 and various data 322 related thereto. Data 322 includes a maintenance database 323 for specifying factors indicating failure of the elevator. In other words, the maintenance database 323 is a database in which trigger notifications and elevator failure symptom factors are matched.

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

The generation processing unit 302 generates a confirmation message for confirming to passengers in the car 1 of the elevator the factors indicating a failure occurring in the elevator, based on the trigger notification received from the monitoring device 8 and the response message described later. do. This processing is hereinafter referred to as “generation processing.” Here, the failure symptom factors include, for example, poor opening and closing of elevator doors, defective buttons, and defective lighting.

A door opening/closing defect is a defect in which the door of the elevator car (1) does not completely close or does not completely open. In addition to equipment failure, door opening/closing defects may also occur due to foreign objects being caught, or the door being pressed by a passenger carrying luggage. Button defects include defects in which buttons, such as the destination floor button, are continuously pressed or do not respond even when pressed. Lighting defects include defects such as burning out or blinking light bulbs in the elevator 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 passengers in the elevator car 1. This processing is hereinafter referred to as “transmission processing”. 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 call device 22 in the elevator car by call processing.

When the passenger who has heard the confirmation message utters a response message using the call device 22 in the elevator car, the monitoring device 8 transmits the response message to the management server 10 through the network 9. The reception processing unit 306 receives a response message from the monitoring device 8 through the network 9. This processing is hereinafter referred to as “reception processing.” The received response message is used for generation processing and decision processing described later.

Based on the response message, the decision processing unit 308 determines whether a maintenance worker needs to be dispatched to the site. This processing is hereinafter referred to as “judgment processing.” In the decision processing, the decision processing unit 308 recognizes the contents of the response message by a known voice recognition function. There is no limitation to the content of the voice recognition function here. The determination processing unit 308 specifies specific failure symptom factors based on the recognition result of the recognized response message and the contents of the trigger notification. Then, the decision processing unit 308 determines whether a maintenance worker needs to be dispatched to the site based on the specified failure symptom factor.

5. Specific processing performed in the maintenance management system of the embodiment

The flow of processing performed by the maintenance management system 100 according to the embodiment will be described using FIGS. 5 and 6.

Fig. 5 is a flowchart showing the control routine of the monitoring process executed by the maintenance management system according to Embodiment 1. The routine shown in FIG. 5 is a routine that is repeatedly executed by the processor 201 of the monitoring device 8.

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. In the next step S102, the processor 201 monitors whether the operation of the elevator contains any signs of failure by executing the monitoring program included in the program 203. As a result, if no fault indications are included, this routine is terminated. On the other hand, if the operation of the elevator includes signs of failure, the process proceeds to step S104. In step S104, the processor 201 generates a trigger notification and transmits it to the management server 10.

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

In step S112, the processor 30 determines whether a trigger notification has been received from the monitoring device 8. As a result, if no trigger notification is received, this routine ends.

On the other hand, when a trigger notification is received in step S112, the process proceeds to step S114. In step S114, the processor 30 transmits a confirmation message to the passenger in the elevator car 1. Here, the processor 30 generates a confirmation message corresponding to the trigger notification in the generation processing unit 302. For example, when the trigger notification includes a malfunction sign of poor door opening/closing, the generation processing unit 302 first generates a confirmation message such as “This is the information center, is there anyone in the elevator car?” The processor 30 transmits the generated confirmation message to the monitoring device 8 through the network 9 in the transmission processing unit 304 . When the processing of step S114 is completed, the processing proceeds to step S116.

The monitoring device 8 transmits a voice confirmation message received from the call device 22 in the elevator car. When the passenger who has heard the confirmation message utters a response message using the call device 22 in the elevator car, the monitoring device 8 transmits the response message to the monitoring device 8 through the network 9.

In step S116, the processor 30 determines whether a response message from the passenger has been received in the reception processing unit 306. As a result, if no response message is received, the process of step S116 is repeatedly executed. On the other hand, when a response message is received, the process proceeds to step S118.

In step S118, the processor 30 receives the response message from the judgment processing unit 308 and determines whether the failure indication factor was able to be specified. Here, the processor 30 uses a voice recognition function to recognize the contents of the received response message. Then, the processor 30 determines whether a specific failure symptom factor could be identified based on the response message. For example, if the response message is “The door is now being pressed so that it does not close due to the loading of the baggage.”, it is determined that the cause of the failure symptom is caused by human work, and the process proceeds to step S120.

Additionally, in another example, if a specific failure symptom factor cannot be identified based on the content of the response message alone, such as "The state of the elevator door opening and closing seems to be strange," the process proceeds to step S122. In step S122, the processor 30 determines whether the confirmation message has been repeated a specified number of times in the judgment processing unit 308. The specified number of times here is the upper limit number of confirmation messages transmitted to specify the cause of the failure symptom. In step S122, when it is determined that the confirmation message has been repeated a specified number of times, it is determined that the failure symptom factor cannot be specified, and the process proceeds to step S124. On the other hand, if the confirmation message is not repeated the specified number of times, it is determined that there is an additional confirmation message to specify the failure symptom factor, 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 in the generation processing unit 302 to further narrow down the failure indication factors. For example, the generation processing unit 302 generates a confirmation message such as “Is something caught in the door?”

As a result, in step S116, if a response message is received, for example, “It seems that something stuck has been removed and restored,” the process proceeds to step S118, and the object for which the failure symptom factor has already been resolved is checked. It is determined that it was an entrapment. Additionally, in another example, when a response message saying "Something still seems strange" is received, the process proceeds to step S118, and the failure symptom factor is specified to be a failure of the device. In step S118, if the failure indication factor can be specified from the contents of the response message, the process proceeds to step 120. If the failure indication factor cannot yet be specified, the process proceeds again to step S122. In this way, the processes of steps S114 to S118 and step 122 are repeatedly executed until the failure indication factor is specified in step S118 or the confirmation message is repeated a specified number of times in step S122.

In step S120, the processor 30 determines, in the judgment processing unit 308, whether a maintenance worker needs to be dispatched based on the failure symptom factor specified in step S118. For example, in the processing of step S118, if it is determined that the cause of the failure symptom is caused by human work, the judgment processing unit 308 determines that dispatch of a maintenance worker is unnecessary and proceeds to step S126. Alternatively, in the processing of step S118, if it is determined that the cause of the failure symptom was jamming of an object that has already been resolved, the judgment processing unit 308 determines that dispatch of a maintenance worker is unnecessary and proceeds to step S126. Alternatively, in the processing of step S118, if it is determined that the failure symptom factor is a failure of the equipment, it is determined that dispatch of a maintenance worker is necessary, and the process proceeds to step S124.

In step S124, the processor 30 requests the dispatch of a maintenance worker. Additionally, in step S124, the generation processing unit 302 generates a message to the effect that a maintenance worker has been requested to be dispatched to the passenger.

In step S126, the processor 30 registers the determination result information including the failure symptom factor in the server memory 32 without requesting the dispatch of a maintenance worker. This processing is called “registration processing.” Additionally, in step S126, the generation processing unit 302 generates a message to the effect that a maintenance worker will not be requested to be dispatched to the passenger.

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

Among the situations in which trigger notifications are generated, there are many signs of failure due to poor handling of elevator equipment in the field. According to the maintenance management system 100, it is possible to determine whether the situation requires dispatch of a maintenance worker by confirming specific failure symptom factors for passengers in the elevator car 1. This can reduce unnecessary dispatch of maintenance personnel.

According to the maintenance management system 100, when a maintenance worker's dispatch request is not made, decision result information including trigger notification and failure symptom factors is registered. As a result, the detailed situation when a failure symptom occurs can be referred to later, and this information can be used for analysis of failure symptom factors, etc.

6. Variation example

The maintenance management system 100 of the present disclosure can adopt a modified form as follows.

There are cases where a passenger in the elevator car 1 wishes to speak to an operator at the information center. Therefore, the operation panel within the elevator car 1 may be provided with an interphone button that is pressed when making a direct call with the operator. In this case, you can put a label next to the intercom button that says “You can talk to the operator by pressing the intercom button.”

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

Among the failure symptom factors of the trigger notification, there are also factors that make it difficult for passengers in the elevator car 1 to confirm with the naked eye or the like. Therefore, the maintenance management system 100 may determine whether to transmit a confirmation message of the failure symptom factor to the passenger in the elevator car 1 when the management server 10 receives the trigger notification. In this case, the maintenance management system 100 stores, for example, a list of failure symptom factors that can be confirmed by passengers in the maintenance database 323, refers to the list, and transmits a confirmation message to the passenger. You just have to decide whether it is necessary or not.

FIG. 7 is a diagram showing a modified example of hardware resources of the management server 10. In the example shown in FIG. 7 , the management server 10 is provided with a processing circuit 34 including, for example, a processor 30, a server memory 32, and dedicated hardware 33. FIG. 7 shows an example in which part of the functions of the management server 10 are realized by dedicated hardware 33. All functions of the management server 10 may be realized by dedicated hardware 33. As dedicated hardware 33, a single circuit, complex circuit, programmed processor, parallel programmed processor, ASIC, FPGA, or a combination thereof may be employed.

Embodiment 2.

2-1. Configuration of the elevator maintenance management system

The maintenance management system of Embodiment 2 has the same system configuration as the maintenance management system 100 of Embodiment 1. For the system configuration of the elevator monitoring system of Embodiment 2, refer to the description of Embodiment 1. The explanation is omitted here.

2-2. Characteristics of the maintenance management system of Embodiment 2

In the maintenance management system 100 of Embodiment 2, when the monitoring device 8 determines that the monitoring data includes a failure sign, the monitoring device 8 confirms the cause of the failure sign for the passengers in the elevator car. Then, it is determined whether it is necessary to transmit a trigger notification. Hereinafter, the flow of processing performed by the maintenance management system 100 according to the present embodiment will be described according to the flow chart in FIG. 8.

Fig. 8 is a flowchart showing the control routine of the processing performed by the maintenance management system according to Embodiment 2. The routine shown in FIG. 8 is a routine that is repeatedly executed by the processor 201 of the monitoring device 8. In steps S202 and S204 of FIG. 8, the processor 201 executes processing similar to steps S102 and S104 of the routine shown in FIG. 5. If it is determined in step S204 that confirmation of the failure symptom factor by the passenger is necessary, the process proceeds to step S206.

In steps S206, S208, S210, S212, and S214, the processor 201 performs the processing performed by the processor 30 of the management server 10 in steps S114, S116, S118, S120, and S122 of the routine shown in FIG. 6. Execute the same processing as.

In the processing of step S212, if it is determined that dispatch of a maintenance worker is necessary, the processing proceeds to step S216, and if it is determined that dispatch of a maintenance worker is unnecessary, this routine ends. In step S216, the processor 201 transmits a trigger notification to the management server 10. The management server 10, which has received the trigger notification, requests dispatch of a maintenance worker.

According to the above control, the monitoring device 8 can confirm the cause of the failure symptom for the passengers in the elevator car 1. As a result, a trigger notification can be transmitted in situations where dispatch of maintenance personnel is required, thereby reducing unnecessary dispatch of maintenance personnel.
