In order to identify the cause of an abnormality that has occurred in an elevator, measurement values related to the operation of the elevator are being acquired. The following Patent Document 1 discloses a technique relating to voltage measurement of an elevator control panel.

Among the measured values, the voltage of the control panel and the like require the worker to go to the installation location of the elevator to measure the voltage, which causes a problem that it takes time and effort to identify the cause of the abnormality. As a solution to this problem, a method in which a measuring device is installed in an elevator in advance and the measured value is transmitted via a wireless network can be considered. This makes it possible to identify the cause of an abnormality at a remote location without the need for workers to go to the elevator installation location.

Japanese Unexamined Patent Publication No. 2001-261249 (published on September 26, 2001)

In order to identify the cause of the abnormality, it is necessary to reliably transmit the measured value indicating that the abnormality has occurred. Therefore, in the above method, the measured value is often transmitted at all times. However, if the measured value is constantly transmitted, there is a problem that the communication cost increases.

One aspect of the present invention has been made in view of this problem, and an object of the present invention is to realize an elevator monitoring system that suppresses the transmission cost of measured values related to the operation of an elevator.

In order to solve the above problems, the elevator monitoring system according to one aspect of the present invention controls and operates a storage device that stores measured values related to the operation of an elevator in operation for a specific period of time and the operation of the elevator. It includes a control device that generates a code according to a situation, and a communication device that transmits a measured value stored in the storage device via a wireless network when the code indicates a specific operating status. There is.

According to the above configuration, by providing the communication device, it is possible to wirelessly transmit the measured value related to the operation of the elevator to a predetermined server or the like via the communication device. Therefore, since it is possible to acquire the measured value at a remote location and identify the cause of the abnormality occurrence, it becomes easy to identify the cause of the abnormality occurrence based on the measured value. If it is configured to communicate with a predetermined server or the like every time a measured value is obtained, the communication cost will increase, but when the code generated in the control device indicates a specific operating status, it is stored in the storage device. By configuring to transmit the measured value, the communication cost can be suppressed.

Further, in the elevator monitoring system according to one aspect of the present invention, the communication device may transmit measured values measured during a predetermined period including the time when the code indicating the specific operating status is generated. ..

According to the above configuration, only the measured values measured during a predetermined period including the time when the code indicating a specific operating status is generated are transmitted, so that the amount of data to be transmitted is suppressed and the cause of the abnormality is identified. Can be facilitated.

Further, in the elevator monitoring system according to one aspect of the present invention, the storage device may store the voltage value of the control device as the measurement value for a specific period.

At present, the voltage of the control device is measured after an abnormality occurs in the elevator, so that the voltage value that can be identified as the cause of the abnormality may not appear in the measurement result. Therefore, when an abnormality occurs due to the voltage, it is difficult to identify the cause. On the other hand, according to the above configuration, since the storage device stores the measured voltage every moment, it becomes easy to identify the cause of the abnormality. In addition, since the communication device is configured to transmit the measured value measured in a predetermined time zone including the time when the specific code is generated, the voltage value in the vicinity where the elevator has reached a specific operating condition must be acquired. This makes it easier to identify the cause of the abnormality.

Further, in the elevator monitoring system according to one aspect of the present invention, the elevator monitoring system includes a plurality of the storage devices, and each of the plurality of the storage devices stores the measured values of different elevators for a specific period of time. The communication device may transmit the measured values stored by each of the plurality of storage devices via the wireless network.

According to the above configuration, in each of the plurality of elevators, the measured value is transmitted when a code indicating a specific operating status is generated, so that the cause of the abnormality can be easily identified. For example, when the measured values of each of the plurality of elevators are transmitted at the same timing, it can be estimated that an event (such as a lightning strike) in which an abnormality occurs in the plurality of elevators at the same time has occurred. On the other hand, when the measured value of only one elevator is transmitted, it can be estimated that an abnormality has occurred only in that elevator.

Further, in the elevator monitoring system according to one aspect of the present invention, when the communication device indicates that an abnormality that causes an abnormal stop of the elevator has occurred, the communication device is a measured value stored in the storage device. May be sent.

According to the above configuration, since only the measured values required when the elevator stops abnormally are transmitted, the cause can be quickly identified, which can lead to the early recovery of the elevator.

According to one aspect of the present invention, there is an effect of suppressing the transmission cost of measured values related to the operation of the elevator.

It is a block diagram which shows an example of the main part structure of the elevator monitoring system which concerns on each embodiment of this invention. It is the schematic which shows a part of the structure of the elevator monitored by the elevator monitoring system shown in FIG. It is a flowchart which shows an example of the flow of the process executed by the elevator monitoring system shown in FIG. It is the schematic which shows a part of the structure of the elevator monitored by the elevator monitoring system shown in FIG.

[Embodiment 1]
The elevator monitoring system according to the embodiment of the present invention will be described with reference to FIGS. 1 to 3. The elevator monitoring system acquires measurement values related to the operation of the elevator and transmits the measurement values via a wireless network. As an example, the elevator monitoring system sends the acquired measured value to the cloud server. As a result, it is possible to grasp the abnormality of the elevator from a remote place capable of communicating with the cloud server.

(System configuration)
First, the configuration of the elevator monitoring system 1 will be described. FIG. 1 is a block diagram showing a main configuration of an elevator monitoring system 1, which is an example of an elevator monitoring system according to the present embodiment. As shown in the figure, the elevator monitoring system 1 includes a control panel 10 (control device), a measuring device 20 (storage device), and a communication device 30. The details of the control panel 10, the measuring device 20, and the communication device 30 will be described later.

(Overview of the elevator)
Next, an outline of the elevator monitored by the elevator monitoring system 1 will be described. FIG. 2 is a schematic view showing a part of the configuration of the elevator 300, which is an example of the elevator according to the present embodiment. The schematic configuration of the elevator is not limited to the illustrated elevator 300.

The illustrated elevator 300 is an elevator provided with a hoistway 31 and a machine room 32. The position of the machine room 32 is not limited to the upper part of the hoistway 31. Further, the elevator 300 may be configured not to include the machine room 32.

As shown, the car 33 of the elevator 300 is connected to one end of the rope 34. A balancing weight 35 is connected to the other end of the rope 34. When the hoisting machine 36 installed in the machine room 32 winds up the rope 34, the car 33 moves up and down in the hoistway 31.

Further, in the machine room 32, the control panel 10, the measuring device 20, and the communication device 30 described above are installed. The control panel 10 controls the operation of the elevator. Specifically, the control panel 10 moves the car 33 to the floor designated by the user and the floor according to the control signals acquired from various buttons (for example, the landing button) provided on the elevator 300. It controls the stop at the car 33, the opening and closing of the doors provided at the car 33 and the landing, and the display change of the position display provided at the landing.

The measuring device 20 measures the measured value related to the operation of the elevator 300 in operation, and stores the measured measured value for a specific period (the oldest measured value is deleted every time a new measured value is stored). In the present embodiment, the measuring device 20 measures the voltage value of the control panel 10 as the measured value and stores it every moment. As the measuring device 20, for example, a commercially available device called a memory high coder (registered trademark) (manufactured by Hioki Electric Co., Ltd.) can be used. The measured value stored in the measuring device 20 may be a value related to the operation of the elevator and is not limited to the voltage value. For example, it may be a value indicating the magnitude of vibration generated in the car of the elevator. That is, the user of the elevator monitoring system 1 may use the measuring device 20 that performs appropriate measurement according to the measurement target.

In the measuring device 20, one of the leads is connected to the terminal 23 (see FIG. 1) of the measuring device 20 in order to measure the voltage value of the measurement target unit 13 (see FIG. 1) of the control panel 10, and the other of the leads is connected. It is connected to the measurement target unit 13. For example, one of the leads is connected to the analog input terminal of the terminals 23 of the measuring device 20. The other end of the lead is connected to the output point (that is, the connector pin) of the control panel 10. There may be a plurality of terminals 23 (channels) of the measuring device 20. As a result, the voltages at a plurality of locations on the control panel 10 can be measured at the same time.

Further, the measuring device 20 has a function of communicating with the control panel 10 and the communication device 30.

The communication device 30 transmits the data received from the measuring device 20 via the wireless network 200. As an example, the wireless network 200 may be a communication network for mobile phones. In the present embodiment, as an example, the communication device 30 transmits the data to the cloud server 100. That is, the communication device 30 is configured to be able to communicate with the cloud server 100 via the wireless network 200. The communication device 30 may be installed in a place different from the machine room 32 as long as it can communicate with the measuring device 20.

Next, the details of the control panel 10, the measuring device 20, and the communication device 30 will be described with reference to FIG. 1 again.

(Details of control panel 10)
The control panel 10 includes a control unit 11, a storage unit 12, and a measurement target unit 13. Further, although not shown, the control panel 10 includes an input unit that receives an operation input of the user. The control unit 11 controls each unit of the control panel 10 in an integrated manner. The storage unit 12 stores various data used by the control panel 10. In the present embodiment, the storage unit 12 stores at least the setting code database 16 described later. The measurement target unit 13 is a general term for a portion of the control panel 10 that measures a voltage value.

The control unit 11 includes an event code generation unit 14 and an event code determination unit 15. The event code generation unit 14 generates an event code according to the operating status of the elevator 300. The event code may be, for example, a code indicating the content of the abnormality when an abnormality occurs in the elevator 300. Further, the event code may be, for example, a two-digit hexadecimal number. The event code generation unit 14 outputs the generated event code to the event code determination unit 15.

The event code determination unit 15 determines whether or not the event code generated by the event code generation unit 14 indicates a specific operating status. When the event code determination unit 15 acquires the event code from the event code generation unit 14, the event code determination unit 15 refers to the setting code database 16 stored in the storage unit 12 and determines whether or not there is a matching event code. Further, the event code determination unit 15 outputs a predetermined signal (hereinafter, referred to as “trigger signal”) indicating whether or not there is a matching event code to the measuring device 20. The trigger signal is input to the measuring device 20 via the terminal 23. One of the leads for outputting the trigger signal from the control panel 10 to the measuring device 20 is connected to the output point (that is, the connector pin) of the control panel 10. Further, the other end of the lead may be connected to the analog input terminal of the measuring device 20 or may be connected to the logic input terminal.

As an example, the event code determination unit 15 outputs either "0" or "1" as a trigger signal. Specifically, the event code determination unit 15 outputs "0" as a trigger signal when the acquired event code does not match the event code of the setting code database 16 or when the event code is not generated. .. On the other hand, when the acquired event code matches the event code of the setting code database 16, "1" is output as a trigger signal.

The setting code database 16 is a database that stores only event codes (hereinafter, referred to as "setting codes") indicating a specific operating status among event codes. The setting code database 16 stores the setting code input via the input unit. As an example, the setting code may be an event code generated when a failure of unknown cause occurs. For example, in the elevator 300 in which the event code "08" indicating an abnormality of the power supply (not shown) of the control panel 10 is rarely generated, the event code of "08" may be stored in the setting code database 16. In the case of this example, the measuring device 20 measures the power supply voltage of the control panel 10. That is, in the case of this example, the lead is connected to the output point in the power supply of the control panel 10. Further, for example, an event code indicating that an abnormality causing an abnormal stop of the elevator 300 has occurred may be stored in the setting code database 16.

(Details of measuring device 20)
The measuring device 20 includes a signal acquisition unit 21, a storage unit 22, a terminal 23, a communication unit 24, and a transmission data identification unit 25. Further, although not shown, the measuring device 20 includes an input unit that receives a user's operation input. Further, the measuring device 20 may include a display unit that performs display processing based on the acquired measured value, a printing unit that performs printing processing based on the acquired measured value, and the like. Further, the measuring device 20 may include a plurality of terminals 23. Further, in addition to the analog input terminal described above, for example, a logic input terminal or the like may be provided.

The signal acquisition unit 21 acquires a signal from the control panel 10. As an example, the signal acquisition unit 21 acquires the measured value and stores the acquired measured value in the storage unit 22. In the present embodiment, the signal acquisition unit 21 acquires the voltage value of the control panel 10 as a measured value. Specifically, with one of the leads connected to the terminal 23 of the measuring device 20 and the other of the leads connected to the voltage value measurement target unit 13 on the control panel 10, a predetermined start is performed for the measuring device 20. When the operation is input, the signal acquisition unit 21 starts measuring the voltage value (acquisition of the voltage value). When the signal acquisition unit 21 starts measuring the voltage value, the signal acquisition unit 21 acquires the voltage value in the measurement target unit 13 of the control panel 10 at predetermined time intervals. In other words, the signal acquisition unit 21 acquires the time-dependent change of the waveform of the voltage value in the measurement target unit 13. The signal acquisition unit 21 stores the time-dependent change of the waveform of the acquired voltage value in the storage unit 22 as measurement data 26.

Further, as an example, the signal acquisition unit 21 acquires a trigger signal via the terminal 23. When the signal acquisition unit 21 acquires "1" as the trigger signal, the signal acquisition unit 21 notifies the transmission data identification unit 25 to that effect.

The storage unit 22 stores various data used by the measuring device 20. In the present embodiment, the storage unit 22 stores at least the above-mentioned measurement data 26.

The communication unit 24 connects to the communication device 30 so as to be able to communicate by wire or wirelessly, and transmits / receives data to / from an external device of the elevator monitoring system 1 via the communication device 30. As an example, the communication unit 24 transmits the voltage value acquired from the transmission data identification unit 25 to the communication device 30. In the present embodiment, the communication unit 24 is realized by a memory card having a communication function by a wireless LAN (for example, Wi-Fi (registered trademark)). However, the communication unit 24 is not limited to this example. As an example, the communication function of the communication unit 24 may be realized as a function of the measuring device 20. In other words, the measuring device 20 may have a function of transmitting / receiving data to / from an external device of the elevator monitoring system 1. Further, the measuring device 20 may directly transmit / receive data to / from an external device. In this case, the elevator monitoring system 1 may be configured not to include the communication device 30.

The transmission data specifying unit 25 specifies the data to be transmitted to the communication device 30. Upon receiving the notification from the signal acquisition unit 21, the transmission data identification unit 25 outputs a part of the measurement data 26 stored in the storage unit 22 to the communication unit 24. Specifically, the transmission data specifying unit 25 outputs the voltage value measured during a predetermined period including the time when the notification is received, that is, the time when "1" is input as the trigger signal, to the communication unit 24. As described above, the time when "1" is input as the trigger signal corresponds to the time when the event code indicating a specific operating status is generated on the control panel 10. Further, the communication unit 24 is realized by a memory card having a wireless LAN function. Therefore, the above-mentioned processing of the transmission data identification unit 25 can also be expressed as the transmission data identification unit 25 storing the voltage value measured in a predetermined period in the communication unit 24. The data format of the measurement data 26 output to the communication unit 24 is not particularly limited, but as an example, it may be CSV format data.

Here, the details of the "predetermined period" will be described. Hereinafter, the predetermined period will be referred to as a “transmission target period”. First, as an example, the length of the transmission target period is set by inputting a predetermined operation to the measuring device 20 before the start of acquisition of the voltage value. This operation can also be expressed as an operation for setting "when" 1 "is input as a trigger signal, the waveform of the voltage value during the transmission target period is recorded in the communication unit 24".
Subsequently, when the transmission data specifying unit 25 receives the notification from the signal acquisition unit 21 (that is, when "1" is input to the measuring device 20 as the trigger signal), the transmission data specifying unit 25 is measured at the time of receiving the notification. The measurement data 26 is specified. The measurement data 26 can also be expressed as measurement data 26 measured at a time when a specific operating condition occurs in the elevator 300.

Subsequently, the transmission data specifying unit 25 sets a time point before a predetermined time when the specified measurement data 26 is measured as a start time point of the transmission target period. Hereinafter, the above-mentioned predetermined time may be referred to as "run-up time". As an example, the run-up time is set by inputting a predetermined operation to the measuring device 20 before the start of acquisition of the voltage value. Further, the run-up time is not particularly limited as long as it is equal to or less than the length of the transmission target period. In other words, as the run-up time, a time equal to or less than the length of the transmission target period can be set. Subsequently, the transmission data specifying unit 25 sets the end time point of the transmission target period based on the start time point and the length of the transmission target period.

Finally, the transmission data specifying unit 25 outputs the measurement data 26 (that is, the voltage value) acquired from the start time to the end time to the communication unit 24. That is, the measuring device 20 transmits the voltage value measured during the transmission target period including the time when a specific operating condition occurs in the elevator 300 to the communication device 30.

The data transmitted by the communication unit 24 to the communication device 30 (for example, the CSV format data described above) includes information on the time when the trigger signal of "1" is input and information indicating the measurement timing of each voltage value. including. As an example, the information indicating the measurement timing of each voltage value may be a value indicating the elapsed time from the time when the trigger signal of "1" is input, which is associated with each voltage value. In the case of this example, a negative value may be associated with each voltage value measured before the trigger signal of "1" is input. As a result, the time when each voltage value is measured can be specified. In addition, the CSV data may further include an identification number for identifying the elevator 300 and the like. As an example, the identification number may be a combination of alphabets and numbers.

(Details of communication device 30)
The communication device 30 transmits to the cloud server 100 a plurality of measurement data 26 including the voltage value associated with the time within the transmission target period received from the measurement device 20. As a result, the user of the elevator monitoring system 1 at a remote location of the elevator 300 can acquire the measurement data 26 from the cloud server 100 and confirm the change over time of the voltage value in the transmission target period.

In addition, the plurality of measurement data 26 include measurement values from a time before the occurrence time when a specific operating condition occurs in the elevator 300 to the occurrence time. Therefore, the user can isolate the cause of the failure by checking the change with time of the voltage value in the transmission target period.

Even if the communication device 30 has a function of changing the data format of the received measurement data 26 to a data format that can be used in an application used for confirming a change in voltage value over time during a transmission target period. Good. As an example, the communication device 30 may change the CSV format data into JSON (JavaScript (registered trademark) Object Notation) format data and transmit it to the cloud server 100.

(Processing flow)
Next, the flow of processing executed by the elevator monitoring system 1 will be described. FIG. 3 is a flowchart showing an example of the flow of the process.

First, the signal acquisition unit 21 of the measuring device 20 starts measuring the voltage of the control panel 10 (S1). As a result, the signal acquisition unit 21 acquires the voltage value in the measurement target unit of the control panel 10 at a predetermined time interval and stores it in the storage unit 22 as the measurement data 26.

Next, when the event code generation unit 14 of the control panel 10 generates an event code (YES in S2), the event code determination unit 15 determines whether or not the event code is a setting code (S3). When it is determined that the setting code is used (YES in S3), the event code determination unit 15 transmits "1" as a trigger signal to the measuring device 20 (S4).

When the signal acquisition unit 21 of the measuring device 20 acquires "1" as a trigger signal, it outputs the measurement data 26 measured in a specific period (transmission target period) to the communication unit 24. The communication unit 24 transmits (outputs) the acquired measurement data 26, that is, the measurement data 26 measured during the transmission target period, to the communication device 30 (S5).

The communication device 30 transmits the acquired voltage value to the cloud server 100 via the wireless network 200 (S6). Then, the processing flow returns to step S2. That is, the measuring device 20 is in a state of waiting for the input of the trigger signal of "1".

In step S3, when the event code determination unit 15 determines that the generated event code is not a setting code (NO in S3), the processing flow returns to step S2 as shown in FIG. That is, the measuring device 20 ends the process and is in a state of waiting for the input of the trigger signal of "1".

(effect)
As described above, the elevator monitoring system 1 according to the present embodiment includes a control panel 10, a measuring device 20, and a communication device 30. The measuring device 20 stores the measured values related to the operation of the operating elevator 300 for a specific period. The control panel 10 controls the operation of the elevator 300 and generates an event code according to the operation status. When the event code indicates a specific operating status, the communication device 30 transmits the measured value stored in the measuring device 20 via the wireless network 200.

According to this configuration, by providing the communication device 30, it is possible to wirelessly transmit the measured value related to the operation of the elevator 300 to a predetermined server (cloud server 100) or the like via the communication device 30. Therefore, since it is possible to acquire the measured value at a remote location and identify the cause of the abnormality occurrence, it becomes easy to identify the cause of the abnormality occurrence based on the measured value. If it is configured to communicate with a predetermined server or the like each time a measured value is obtained, the communication cost will increase. Therefore, when the event code generated by the control panel 10 indicates a specific operating status, the communication cost can be suppressed by configuring the measurement device 20 to transmit the measured value stored in the measuring device 20. Further, with such a configuration, it is possible to reliably transmit the measured value that may indicate the cause of the occurrence of the abnormality without communicating every time the measured value is obtained.

Further, as described above, the communication device 30 transmits the measured value measured during the transmission target period. Here, the transmission target period is a period including a time when an event code indicating a specific operating status is generated.

According to this configuration, the measured value measured during the transmission target period including the time when the event code indicating the specific operating status is generated is transmitted, so that the amount of data to be transmitted is suppressed and the cause of the abnormality can be easily identified. Can be transformed into.

Further, as described above, the measuring device 20 stores the voltage value of the control panel 10 as the measured value.

At present, since the measurement of the voltage value of the control panel 10 is started after an abnormality occurs in the elevator 300, the voltage value that can be identified as the cause of the abnormality may not appear in the measurement result. Therefore, when an abnormality occurs due to the voltage value, it is difficult to identify the cause. On the other hand, according to the above configuration, since the measuring device 20 stores the measured voltage every moment, it becomes easy to identify the cause of the abnormality.

Further, as described above, the communication device 30 transmits the measured value stored in the measuring device 20 when the event code indicates that an abnormality causing an abnormal stop of the elevator 300 has occurred.

According to this configuration, since the measured value is transmitted when there is a high possibility that the elevator has stopped abnormally, the cause can be quickly identified, which can lead to the early recovery of the elevator.

In the above-mentioned example, the control panel 10 determines whether or not the event code generated by the control panel 10 is a setting code. Instead of this configuration, the measuring device 20 may determine whether or not the event code generated by the control panel 10 is a setting code. In the case of this example, the control panel 10 and the measuring device 20 are communicably connected, and the control panel 10 may transmit the generated event code to the measuring device 20.

According to this configuration, it is possible to realize the elevator monitoring system 1 that determines whether or not the event code is in a specific operating state by simply adding the measuring device 20 to the elevator 300 that is already in operation. That is, in the elevator 300 that is already in operation, it is not necessary to modify the installed control panel 10, so that such an elevator monitoring system 1 can be easily realized.

In particular, the communication environment can be easily improved in an old-fashioned elevator that cannot be said to have a sufficient communication environment. As a result, the cause of failure can be easily identified even in an old-fashioned elevator.

[Embodiment 2]
An elevator monitoring system according to another embodiment of the present invention will be described with reference to FIG. FIG. 4 is a schematic view showing a part of the structure of the elevator according to the present embodiment. For convenience of explanation, the same reference numerals will be added to the members having the same functions as the members described in the above embodiment, and the description will not be repeated.

The elevator monitoring system 1 according to the present embodiment includes a plurality of measuring devices, and in the example shown in FIG. 4, four measuring devices 20A to 20D are provided. The measuring devices 20A to 20D store the measured values in the elevators 300A to 300D, respectively. In the present embodiment, as an example, the measuring devices 20A to 20D measure the voltage of the control panels 10A to 10D provided in the machine room 32 of the elevators 300A to 300D, respectively. When it is not necessary to distinguish between the control panels 10A to 10D, the measuring devices 20A to 20D, and the elevators 300A to 300D, they are collectively referred to as the control panel 10, the measuring device 20, and the elevator 300, respectively.

On the other hand, the elevator monitoring system 1 according to the present embodiment includes only one communication device 30 as in the first embodiment. That is, the communication device 30 receives the voltage value of the transmission target period from each of the measuring devices 20A to 20D and transmits it to the cloud server 100 via the wireless network 200. Therefore, the communication device 30 is installed in a place where it can communicate with all of the measuring devices 20A to 20D. In the illustrated example, the communication device 30 is provided in the machine room 32 of the elevator 300B, but the installation position of the communication device 30 is not limited to this example.

The measuring devices 20A to 20D associate the voltage value during the transmission target period with information that can identify the own device, and transmit the information to the communication device 30. As a result, it is possible to indicate to the user who confirms the voltage value at a remote location of the elevator 300 which elevator 300 the acquired voltage value is. The measuring devices 20A to 20D can identify the information that can identify the elevator 300 to be measured by the own device or the control panel 10 to which the own device is connected, instead of the information that can identify the own device. Information may be associated.

Further, in the illustrated example, the number of communication devices 30 is only one, but the elevator monitoring system 1 according to the present embodiment may include a plurality of communication devices 30. For example, one communication device 30 may be provided for one measuring device 20.

(effect)
As described above, the elevator monitoring system 1 according to the present embodiment includes a plurality of measuring devices 20. Each of the plurality of measuring devices 20 stores the measured values of different elevators 300 for a specific period of time. The communication device 30 transmits the measured values stored by each of the plurality of measuring devices 20 via the wireless network 200.

According to this configuration, when an event code indicating a specific operating status is generated in each of the plurality of elevators 300, the measured value is transmitted, so that the cause of the abnormality can be easily identified. For example, when the measured values of the plurality of elevators 300 are transmitted at the same timing, it can be estimated that an abnormality has occurred in the plurality of elevators 300 at the same time due to an event such as a lightning strike. On the other hand, when the measured value of only one elevator 300 is transmitted, it can be estimated that an abnormality has occurred only in that elevator 300.

When the measuring device 20 has a plurality of terminals 23 and the control panels 10 of the plurality of elevators 300 are present in one space, the output points of the control panels 10 and the terminals 23 are read by reading. If connected, one measuring device 20 can measure the voltage value of the control panel 10 of each of the plurality of elevators 300.
