Description

  The present invention relates to an elevator monitoring system that acquires measurement values related to elevator operation and transmits the measurement values to an external device.

  In order to identify the cause of the abnormality that has occurred in the elevator, a measurement value relating to the operation of the elevator is acquired. Patent Document 1 below discloses a technique related to voltage measurement of an elevator control panel.

  Among the measured values, the voltage of the control panel, etc., has to be measured by an operator visiting the elevator installation site, which takes time to identify the cause of the abnormality. As a solution to this problem, a method in which a measurement device is installed in an elevator in advance and a measurement value is transmitted via a wireless network can be considered. As a result, the cause of the occurrence of the abnormality can be identified at a remote location without the worker going to the elevator installation location.

JP 2001-261249 A (published September 26, 2001)

  In order to identify the cause of the abnormality, it is necessary to reliably transmit a measurement value indicating that the abnormality has occurred. For this reason, in many cases, the above-described method is configured to constantly transmit measurement values. However, when the measurement 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 thereof is to realize an elevator monitoring system that suppresses the transmission cost of measurement values related to operation of an elevator.

  In order to solve the above-described problem, an elevator monitoring system according to one aspect of the present invention controls a storage device that stores measurement values related to operation of an elevator in operation for a specific period, and controls the operation of the elevator, 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 operation status. Yes.

  According to said structure, by providing a communication apparatus, the measured value regarding the operation | movement of an elevator can be wirelessly transmitted to a predetermined | prescribed server etc. via this. Therefore, it is possible to acquire the measurement value at a remote place and specify the cause of the abnormality, and therefore it becomes easy to specify the cause of the abnormality based on the measurement value. If it is configured to communicate with a predetermined server or the like every time a measurement value is obtained, the communication cost increases. However, if the code generated in the control device indicates a specific operation status, it is stored in the storage device. By configuring so as to transmit the measured value, the communication cost can be suppressed.

  Moreover, the elevator monitoring system which concerns on 1 aspect of this invention WHEREIN: The said communication apparatus may transmit the measured value measured in the predetermined | prescribed period including the time of producing | generating the code which shows the said specific operation condition. .

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

  Moreover, the elevator monitoring system which concerns on 1 aspect of this invention WHEREIN: The said memory | storage device may memorize | store the voltage value of the said control apparatus for a specific period as the said measured value.

  Currently, since the voltage of the control apparatus starts measurement after an abnormality occurs in the elevator, a voltage value that can be identified as the cause of the abnormality may not appear in the measurement result. For this reason, 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 specify the cause of the occurrence of the abnormality. In addition, since the communication device is configured to transmit a measurement 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 is in the specific operation state is acquired. This makes it easy 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 storage devices stores the measured values of different elevators for a specific period, The communication device may transmit measurement values stored in each of the plurality of storage devices via the wireless network.

  According to said structure, since the measured value is transmitted when the code | cord | chord which shows a specific operation condition is produced | generated in each of several elevators, specification of the cause of abnormality occurrence becomes easy. 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) has occurred that causes an abnormality in the plurality of elevators at the same time. On the other hand, when a measured value of only one elevator is transmitted, it can be estimated that an abnormality has occurred only for that elevator.

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

  According to said structure, since only a measured value required when an elevator stops abnormally, a cause identification can be started quickly and it can lead to the early recovery of an elevator.

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

It is a block diagram which shows an example of the principal part structure of the elevator monitoring system which concerns on each embodiment of this invention. It is the schematic which shows a part of 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 which the elevator monitoring system shown in FIG. 1 performs. It is the schematic which shows a part of structure of the elevator monitored by the elevator monitoring system shown in FIG.

Embodiment 1
An elevator monitoring system according to an embodiment of the present invention will be described with reference to FIGS. The elevator monitoring system acquires measurement values related to elevator operation and transmits the measurement values via a wireless network. As an example, the elevator monitoring system transmits the acquired measurement value to the cloud server. Thereby, the abnormality of an elevator can be grasped | ascertained from the remote place which can communicate with the said cloud server.

(System configuration)
First, the configuration of the elevator monitoring system 1 will be described. FIG. 1 is a block diagram illustrating a main configuration of an elevator monitoring system 1 that is an example of an elevator monitoring system according to the present embodiment. The elevator monitoring system 1 includes a control panel 10 (control device), a measurement device 20 (storage device), and a communication device 30 as illustrated. Details of the control panel 10, the measuring device 20, and the communication device 30 will be described later.

(Elevator overview)
Next, an outline of the elevator monitored by the elevator monitoring system 1 will be described. FIG. 2 is a schematic diagram illustrating a part of the configuration of an elevator 300, which is an example of an 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 including a hoistway 31 and a machine room 32. The position of the machine room 32 is not limited to the upper side of the hoistway 31. Further, the elevator 300 may be configured not to include the machine room 32.

  As illustrated, the car 33 of the elevator 300 is connected to one end of the rope 34. A counterweight 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.

  In the machine room 32, the above-described control panel 10, measuring device 20, and communication device 30 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 in accordance with control signals acquired from various buttons (for example, landing buttons) provided on the elevator 300 and the floor. Control of stopping at the car, opening and closing of the car 33 and the door provided at the landing, and changing the display of the position indicator provided at the landing.

  The measuring device 20 measures a measurement value related to the operation of the elevator 300 that is in operation, and stores the measured value for a specific period (deletes the oldest measurement value each time a new measurement 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 momentarily. As the measuring device 20, for example, a commercially available device called Memory HiCorder (registered trademark) (manufactured by Hioki Electric Co., Ltd.) can be used. In addition, the measured value which the measuring device 20 memorize | stores should just be a value regarding operation | movement of an elevator, and is not limited to a voltage value. For example, it may be a value indicating the magnitude of vibration generated in the elevator car. 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, in order to measure the voltage value of the measurement target portion 13 (see FIG. 1) of the control panel 10, one of the leads is connected to the terminal 23 (see FIG. 1) of the measuring device 20, and the other of the leads is Connected to the measurement target unit 13. For example, one of the leads is connected to an analog input terminal of the terminals 23 of the measuring device 20. The other end of the lead is connected to an output point (that is, a connector pin) of the control panel 10. Note that there may be a plurality of terminals 23 (channels) of the measuring device 20. Thereby, the voltage of several places in the control panel 10 can be measured simultaneously.

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

  The communication device 30 transmits data received from the measurement 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. Note that the communication device 30 may be installed at a location different from the machine room 32 as long as it can communicate with the measurement device 20.

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

(Details of control panel 10)
The control panel 10 includes a control unit 11, a storage unit 12, and a measurement target unit 13. Moreover, although not shown in figure, the control panel 10 is provided with the input part which receives a user's operation input. The control unit 11 controls each part 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 a setting code database 16 described later. The measurement target unit 13 is a generic name for portions of the control panel 10 that measure voltage values.

  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 corresponding to the operating status of the elevator 300. For example, when an abnormality occurs in the elevator 300, the event code may be a code indicating the content of the abnormality. Further, the event code may be, for example, a 2-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 operation 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 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 measurement 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 an output point (that is, a connector pin) of the control panel 10. The other of the leads may be connected to an analog input terminal of the measuring device 20 or may be connected to a logic input terminal.

  For example, the event code determination unit 15 outputs “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 in the setting code database 16 and when the event code is not generated. . On the other hand, if the acquired event code matches the event code in 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 operation status among event codes. The setting code database 16 stores setting codes 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, an event code “08” may be stored in the setting code database 16 in the elevator 300 in which “08”, which is an event code indicating an abnormality of the power supply (not shown) of the control panel 10, is rarely generated. In this example, the measuring device 20 measures the power supply voltage of the control panel 10. That is, in this example, the lead is connected to an output point in the power source of the control panel 10. Further, for example, an event code indicating that an abnormality that causes 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 specifying unit 25. Moreover, although not shown in figure, the measuring device 20 is provided with the input part which receives a user's operation input. Furthermore, the measurement device 20 may include a display unit that performs a display process based on the acquired measurement value, a printing unit that performs a print process based on the acquired measurement value, and the like. Further, the measuring device 20 may include a plurality of terminals 23. In addition to the analog input terminals described above, for example, a logic input terminal 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 a measurement value, and stores the acquired measurement 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 the measurement value. Specifically, with one of the leads connected to the terminal 23 of the measuring device 20 and the other lead connected to the voltage value measurement target portion 13 in the control panel 10, a predetermined start is made to the measuring device 20. When an operation is input, the signal acquisition unit 21 starts measuring a voltage value (acquisition of a voltage value). When the measurement of the voltage value is started, the signal acquisition unit 21 acquires the voltage value in the measurement target unit 13 of the control panel 10 at a predetermined time interval. In other words, the signal acquisition unit 21 acquires a temporal change in the waveform of the voltage value in the measurement target unit 13. The signal acquisition unit 21 stores the change in the waveform of the acquired voltage value over time as measurement data 26 in the storage unit 22.

  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 measurement device 20. In the present embodiment, the storage unit 22 stores at least the measurement data 26 described above.

  The communication unit 24 is connected to the communication device 30 so as to be communicable by wire or wirelessly, and transmits / receives data to / from devices outside 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 specifying 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 using 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 measurement 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 send and receive data with an external device. In this case, the elevator monitoring system 1 may have a configuration that does not include the communication device 30.

  The transmission data specifying unit 25 specifies data to be transmitted to the communication device 30. Upon receiving the notification from the signal acquisition unit 21, the transmission data specifying 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 a 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 point when “1” is input as the trigger signal corresponds to the time point when the event code indicating the specific operation status is generated in the control panel 10. The communication unit 24 is realized by a memory card having a wireless LAN function. For this reason, the process of the transmission data specification part 25 mentioned above can also be expressed as the transmission data specification part 25 storing the voltage value measured in the predetermined period in the communication part 24. FIG. In addition, the data format of the measurement data 26 output to the communication unit 24 is not particularly limited, but may be CSV format data as an example.

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

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

  Finally, the transmission data specifying unit 25 outputs the measurement data 26 (that is, 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 point when the specific operation status occurs in the elevator 300 to the communication device 30.

  Note that data (for example, the data in the CSV format described above) transmitted from the communication unit 24 to the communication device 30 includes information on the time when the trigger signal “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 “1” associated with each voltage value is input. In this example, a negative value may be associated with each voltage value measured before the trigger signal “1” is input. Thereby, the time when each voltage value was measured can be specified. The CSV data may further include an identification number for specifying the elevator 300. 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 received from the measurement device 20 and including voltage values associated with times within the transmission target period. Thereby, the user of the elevator monitoring system 1 located at a remote location of the elevator 300 can acquire the measurement data 26 from the cloud server 100 and confirm the change with time of the voltage value in the transmission target period.

  Further, the plurality of measurement data 26 includes measurement values from the time before the occurrence time when the specific operation status occurs in the elevator 300 to the occurrence time. For this reason, the user can identify the cause of the failure by confirming the temporal change 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 by an application used for confirming a change with time of the voltage value in the transmission target period. Good. As an example, the communication device 30 may change the data in the CSV format into data in the JSON (JavaScript (registered trademark) Object Notation) format and transmit the data to the cloud server 100.

(Process 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 processing.

  First, the signal acquisition unit 21 of the measuring device 20 starts measuring the voltage of the control panel 10 (S1). Thereby, 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 determines with it being a setting code (it is YES at S3), the event code determination part 15 transmits "1" to the measuring device 20 as a trigger signal (S4).

  When acquiring “1” as the trigger signal, the signal acquisition unit 21 of the measurement device 20 outputs the measurement data 26 measured during 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 process flow returns to step S2. That is, the measuring apparatus 20 is in a state of waiting for the input of the trigger signal “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 process flow returns to step S2, as shown in FIG. That is, the measuring apparatus 20 ends the process and enters a state of waiting for the input of the trigger signal “1”.

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

  According to this configuration, by providing the communication device 30, it is possible to wirelessly transmit a measurement 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, it is possible to acquire the measurement value at a remote place and specify the cause of the abnormality, and therefore it becomes easy to specify the cause of the abnormality based on the measurement value. If it is configured to communicate with a predetermined server or the like every time a measurement value is obtained, the communication cost increases. Therefore, when the event code generated in the control panel 10 indicates a specific operation status, the communication cost can be suppressed by configuring the measurement value stored in the measurement device 20 to be transmitted. Moreover, by configuring in this way, it is possible to reliably transmit a measurement value that may indicate the cause of an abnormality without communication every time a measurement value is obtained.

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

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

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

  Currently, since the voltage value of the control panel 10 is measured 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. For this reason, when an abnormality occurs due to the voltage value, it is difficult to identify the cause. On the other hand, according to said structure, since the measuring device 20 memorize | stores the measured voltage moment by moment, specification of the cause of abnormality generation becomes easy.

  In addition, as described above, the communication device 30 transmits the measurement value stored in the measurement device 20 when the event code indicates that an abnormality that causes 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 and the elevator can be recovered early.

  In the above-described example, the control panel 10 determines whether or not the event code generated on the control panel 10 is a setting code. Instead of this configuration, the measurement device 20 may determine whether or not the event code generated in the control panel 10 is a setting code. In this example, the control panel 10 and the measurement device 20 are connected to be communicable, and the control panel 10 may transmit the generated event code to the measurement 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 already operating elevator 300. That is, in the elevator 300 that is already in operation, it is not necessary to modify the installed control panel 10, and thus such an elevator monitoring system 1 can be easily realized.

  In particular, the communication environment can be easily maintained in an old-style elevator that cannot be said to have a sufficient communication environment. As a result, the cause of the failure can be easily identified even in the old 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 configuration of the elevator according to the present embodiment. For convenience of explanation, members having the same functions as those described in the above embodiment are given the same reference numerals, and the description thereof will not be repeated.

  The elevator monitoring system 1 according to the present embodiment includes a plurality of measuring devices, and in the example illustrated in FIG. 4, includes four measuring devices 20A to 20D. Measuring devices 20A-20D memorize a measurement value in elevators 300A-300D, respectively. In the present embodiment, as an example, the measuring devices 20A to 20D measure the voltages of the control panels 10A to 10D provided in the machine rooms 32 of the elevators 300A to 300D, respectively. In addition, when it is not necessary to distinguish between the control panels 10A to 10D, the measurement devices 20A to 20D, and the elevators 300A to 300D, they are collectively referred to as the control panel 10, the measurement 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 measurement devices 20 </ b> A to 20 </ b> D and transmits the voltage value to the cloud server 100 via the wireless network 200. For this reason, the communication apparatus 30 is installed in the place which can communicate with all of measuring device 20A-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.

  In addition, measuring device 20A-20D matches the voltage value of a transmission object period with the information which can identify an own apparatus, and transmits to the communication apparatus 30. FIG. Thereby, it can be shown to which user the voltage value acquired in which elevator 300 to the user who confirms this voltage value in the remote place of the elevator 300. FIG. Note that the measuring devices 20A to 20D can identify information that can identify the elevator 300 that is subject to measurement, or the control panel 10 to which the own device is connected, instead of information that can identify the own device. Information may be associated.

  In the illustrated example, only one communication device 30 is provided, 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 measurement device 20.

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

  According to this configuration, since the measurement value is transmitted when an event code indicating a specific operation status is generated in each of the plurality of elevators 300, the cause of the occurrence of an 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 simultaneously due to an event such as a lightning strike. On the other hand, when a measured value of only one elevator 300 is transmitted, it can be estimated that an abnormality has occurred only for 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 exist in one space, the output point of each control panel 10 and each terminal 23 are connected with leads. When connected, the voltage value of the control panel 10 of each of the plurality of elevators 300 can be measured with one measuring device 20.

[Example of software implementation]
The control blocks (especially the control unit 11 and the transmission data specifying unit 25) of the control panel 10 and the measuring device 20 may be realized by a logic circuit (hardware) formed in an integrated circuit (IC chip) or the like, or software It may be realized by.

  In the latter case, the control panel 10 and the measuring device 20 include a computer that executes instructions of a program that is software for realizing each function. The computer includes, for example, one or more processors and a computer-readable recording medium storing the program. In the computer, the processor reads the program from the recording medium and executes the program, thereby achieving the object of the present invention. As the processor, for example, a CPU (Central Processing Unit) can be used. As the recording medium, a “non-temporary tangible medium” such as a ROM (Read Only Memory), a tape, a disk, a card, a semiconductor memory, a programmable logic circuit, or the like can be used. Further, a RAM (Random Access Memory) for expanding the program may be further provided. Further, the program may be supplied to the computer via any transmission medium (such as a communication network or a broadcast wave) that can transmit the program. Note that one embodiment of the present invention can also be realized in the form of a data signal embedded in a carrier wave, in which the program is embodied by electronic transmission.

  The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope shown in the claims, and embodiments obtained by appropriately combining technical means disclosed in different embodiments. Is also included in the technical scope of the present invention.
