Therefore, measures can be taken to prevent the information terminal from deleting the first data corresponding to the second data. In other words, it is possible to prevent the measurement data obtained as a result of the information terminal measuring the measurement target from being deleted.

[0011] According to the above configuration, it is possible to reduce the possibility that the first data is completely deleted from the information terminal.

[0012] An elevator management system according to aspect 4 of the present invention may be such that, in any of aspects 1 to 3 above, when the information terminal receives the notification, it transmits the first data corresponding to the second data to the management device.

DETAILED DESCRIPTION OF THE INVENTION

[0023] [Embodiment 1] An embodiment of the present invention will be described in detail below. FIG. 1 is a block diagram showing the configuration of a main part of an elevator management system 100A according to this embodiment. As shown in FIG. 1, the elevator management system 100A includes an information terminal 10A and a management device 50. In the elevator management system 100A, the information terminal 10A outputs data created based on the results of measuring a measurement target related to an elevator to the management device 50, and the management device 50 determines whether or not there is an abnormality in the data. The information terminal 10A and the management device 50 will be described in detail below.

[0024] (Information terminal 10A) The information terminal 10A is a portable device with a communication function. The information terminal 10A is capable of communicating with the management device 50. The information terminal 10A may be, for example, a smartphone, a tablet, or the like. The information terminal 10A is carried by a measurer who uses the information terminal 10A to measure an object to be measured in an elevator. The information terminal 10A includes an input unit 11, a communication unit 12, a memory unit 13, a display unit 14 capable of displaying various information, a measurement unit 20 (first data creation unit), and a control unit 30A.

[0025] The input unit 11 receives input to the information terminal 10 A. The input unit 11 includes a touch panel for receiving operation input, a microphone for receiving voice input, a camera for image input, and the like.

[0026] The communication unit 12 communicates with external devices such as the management device 50 via a network 90. ​​The network 90 may be, for example, the Internet.

[0027] The storage unit 13 stores various data used by the information terminal 10A. The storage unit 13 also stores data created by the measurement unit 20, which will be described later. The storage unit 13 is configured by a storage device such as a DRAM (Dynamic Random Access Memory).

[0028] The measurement unit 20 generates data (hereinafter also referred to as first data) as a result of measuring a measurement object related to the elevator. The measurement unit 20 in this embodiment includes an acceleration sensor 21 and a sound sensor 22 as measurement devices. The measurement devices included in the measurement unit 20 are not limited to the acceleration sensor 21 and the sound sensor 22. The measurement unit 20 may also include other measurement devices (for example, a barometric pressure sensor, an illuminance sensor, etc.) that measure other measurement objects related to the elevator.

[0029] The acceleration sensor 21 is a sensor that measures acceleration. The acceleration sensor 21 measures changes in the acceleration of an elevator as a measurement target, generates data (i.e., first data) that is the measurement result, and stores the data in the storage unit 13.

[0030] The sound sensor 22 is a sensor that measures sound and creates sound wave signal data. The sound sensor 22 may use the microphone provided in the input unit 11. The sound wave signal data may be data obtained by measuring the volume at a predetermined period. The sound sensor 22 measures the sound inside the elevator as the measurement target, creates sound wave signal data (i.e., first data), and stores the data in the storage unit 13.

[0031] The control unit 30A controls each unit of the information terminal 10A. The control unit 30A controls the execution of each function of the information terminal 10A in response to, for example, an input operation on the touch panel of the input unit 11. The control unit 30A includes a data processing unit 31 (second data creation unit), a transmission unit 32 (first transmission unit), and a display control unit 33 that controls the display of the display unit 14.

[0032] The data processing unit 31 reads the first data created by the measurement unit 20 from the storage unit 13 and processes the first data to create data (hereinafter also referred to as second data) with a smaller amount of data than the first data. For example, the data processing unit 31 may thin out a portion of the acceleration waveform obtained by measuring changes in elevator acceleration and created by the acceleration sensor 21, thereby creating an acceleration waveform with a smaller amount of data than the first data as the second data. In this case, the data processing unit 31 may include a waveform indicating the elevator speed and / or a waveform indicating the elevator displacement created based on the acceleration waveform. The data processing unit 31 may also perform FFT (Fast Fourier transformation) analysis on the acceleration waveform created by measuring changes in elevator acceleration and create the FFT results (e.g., analysis range, FFT peak frequency, FFT peak value, etc.) as the second data. The data processing unit 31 may also create the peak-to-peak value of the acceleration waveform as the second data.

[0033] As another example, the data processing unit 31 may create second data having a smaller amount of data than the first data by thinning out a portion of the sound wave signal data created by the sound sensor 22.

[0034] The data processing unit 31 may have the function of creating a report that describes the first data created by the measurement unit 20 and the second data generated as described above, and displaying it on the display unit 14 of the information terminal 10A.

[0035] The transmitting unit 32 transmits the second data created by the data processing unit 31 to the management device 50 via the communication unit 12.

[0036] (Management device 50) The management device 50 manages the elevators. The management device 50 may be, for example, a computer. As shown in Fig. 1, the management device 50 includes an input unit 51 that receives input to the management device 50, a communication unit 52, a storage unit 53, a display unit 54 that displays various information, and a control unit 60.

[0037] The communication unit 52 communicates with external devices such as the information terminal 10A via the network 90.

[0038] The storage unit 53 stores various data used by the management device 50. The storage unit 53 also stores data created in the past as the results of measuring elevator-related measurement targets. Hereinafter, this data will be referred to as past data.

[0039] The control unit 60 controls each unit of the management device 50. The control unit 60 controls the execution of each function of the management device 50 in response to, for example, an input operation on the input unit 51. The control unit 60 includes a determination unit 61 and a transmission unit 62 (second transmission unit).

[0040] The determination unit 61 determines whether or not there is an abnormality in the second data based on the second data transmitted from the information terminal 10A. For example, the determination unit 61 may determine whether or not there is an abnormality in the second data by comparing the second data with the above-mentioned past data. Alternatively, the determination unit 61 may determine whether or not there is an abnormality in the second data based on the second data by determining whether or not the elevator vibration derived from the first data created based on the acceleration measured by the acceleration sensor 21 and / or the noise derived from the sound wave signal data measured by the sound sensor 22 exceed a predetermined threshold.

[0041] When the determination unit 61 determines that the second data has an abnormality, the transmission unit 62 transmits a notification to the information terminal 10A via the communication unit 52, notifying the information terminal 10A of the abnormality. Here, when it is determined that the second data has an abnormality, it is necessary to acquire the first data corresponding to the second data in order to examine the abnormality in detail. However, the measurer may delete the first data due to reasons such as low remaining storage capacity of the information terminal 10A. Therefore, in the elevator management system 100A, the transmission unit 62 transmits a notification to the information terminal 10A notifying the information terminal 10A of the abnormality, thereby preventing the measurer from deleting the first data.

[0042] (An example of processing by the elevator management system 100A) Next, an example of elevator management processing by the elevator management system 100A will be described with reference to Fig. 2. Fig. 2 is a flowchart showing an example of elevator management processing by the elevator management system 100A.

[0043] In the elevator management process by the elevator management system 100A, first, the measurement unit 20 of the information terminal 10A measures the elevator-related measurement object based on the operation of the measurer, and creates first data (step S1). The created first data is stored in the storage unit 13.

[0044] Next, the data processing unit 31 reads out the first data created by the measurement unit 20 from the storage unit 13, and processes the first data to create second data having a smaller amount of data than the first data (step S2).

[0045] Next, the transmitting unit 32 transmits the second data created by the data processing unit 31 to the management device 50 via the communication unit 12 (step S3), and the management device 50 receives the second data (step S11).

[0046] Next, the determination unit 61 of the management device 50 determines whether there is an abnormality in the second data transmitted from the information terminal 10A (step S12). If the determination unit 61 determines that there is no abnormality in the second data (NO in step S12), the process ends.

[0047] On the other hand, if the judgment unit 61 judges that there is an abnormality in the second data (YES in step S12), the transmission unit 62 transmits a notification to the information terminal 10A via the communication unit 52 informing that there is an abnormality in the second data (step S13), and the notification is received by the information terminal 10A (step S21).

[0048] Next, when information terminal 10A receives the notification, display control unit 33 of information terminal 10A causes display unit 14 to display a message indicating that there is an abnormality in the second data (step S22). This allows the measurer to recognize that there is an abnormality in the second data by looking at the message on display unit 14. When the measurer confirms the message indicating that there is an abnormality in the second data displayed on display unit 14, he or she transmits the first data corresponding to the second data stored in memory unit 13 to management device 50. This allows management device 50 to perform a detailed analysis of whether or not there is an abnormality in the elevator based on the first data, which is more detailed than the second data.

[0049] As described above, in the elevator management system 100A of this embodiment, when the management device 50 determines that there is an abnormality in the second data, it transmits a notification to the information terminal 10A informing the information terminal 10A that there is an abnormality in the second data. Then, the display control unit 33 of the information terminal 10A causes the display unit 14 to display a message indicating that there is an abnormality in the second data. This allows the measurer to recognize that there is an abnormality in the second data, and therefore allows the first data corresponding to the second data to be transmitted to the management device 50 before being deleted. In other words, it is possible to prevent the first data, which is measurement data obtained by the information terminal 10A measuring the measurement target, from being deleted before being transmitted to the management device 50.

[0050] In the elevator management system 100A of the present embodiment, when the information terminal 10A receives a notification indicating that the second data has an abnormality, the information terminal 10A displays a message indicating that the second data has an abnormality on the display unit 14. However, the present invention is not limited to this configuration. In an elevator management system 100A according to one aspect of the present invention, when the information terminal 10A receives a notification indicating that the second data has an abnormality, the information terminal 10A may automatically transmit first data corresponding to the second data to the management device 50. This allows the first data, which is measurement data obtained by the information terminal 10A measuring the measurement target, to be transmitted to the management device 50 before the first data is deleted. In this configuration, the information terminal 10A may be permanently installed in the elevator rather than being carried by the person performing the measurement. In this case, the information terminal 10A may be configured to periodically perform measurements using the measurement unit 20, create second data, and transmit the second data to the management device 50.

[0051] [Embodiment 2] Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0052] Fig. 3 is a block diagram showing the configuration of a main part of an elevator management system 100B according to this embodiment. As shown in Fig. 3, the elevator management system 100B includes an information terminal 10B instead of the information terminal 10A in embodiment 1. The information terminal 10B includes a control unit 30B instead of the control unit 30A in embodiment 1.

[0053] The control unit 30B includes a backup data creation unit 34 in addition to the configuration of the control unit 30A in the first embodiment. When the information terminal 10B receives a notification from the management device 50 via the communication unit 12 notifying that there is an abnormality in the second data, the backup data creation unit 34 creates backup data of the first data corresponding to the second data. For example, the backup data creation unit 34 may create the backup data in a folder different from the folder in which the first data is stored in the storage unit 13. The backup data may be data obtained by losslessly compressing the first data to reduce its data size.

[0054] According to the above configuration, when information terminal 10B receives a notification that there is an abnormality in the second data, backup data of the first data corresponding to the second data is automatically created. This allows the backup data to remain in information terminal 10B even if the first data previously stored in storage unit 13 is deleted. In other words, it is possible to reduce the possibility that the first data will be completely deleted from the information terminal.

[0055] [Embodiment 3] Another embodiment of the present invention will be described below. Fig. 4 is a block diagram showing the configuration of the main parts of an elevator management system 100C according to this embodiment. As shown in Fig. 4, the elevator management system 100C includes an information terminal 10C instead of the information terminal 10A in the first embodiment. The information terminal 10C includes a control unit 30C instead of the control unit 30A in the first embodiment.

[0056] The control unit 30C includes a data deletion disable setting unit 35 in addition to the configuration of the control unit 30A in embodiment 1. When the information terminal 10B receives a notification from the management device 50 via the communication unit 12 notifying that there is an abnormality in the second data, the data deletion disable setting unit 35 sets the first data corresponding to the second data to be deletion disable.

[0057] According to the above configuration, when the information terminal 10B receives a notification that there is an abnormality in the second data, the first data corresponding to the second data can be set to be non-deletable, thereby preventing the first data from being deleted.

[0058] [Software implementation example] The functions of the information terminals 10A to 10C or the management device 50 (hereinafter referred to as "device") can be realized by a program that causes a computer to function as the device, and a program that causes a computer to function as each control block of the device (particularly each part included in the control units 30A to 30C or the control unit 60).

[0059] In this case, the device includes a computer having at least one control device (e.g., a processor) and at least one storage device (e.g., a memory) as hardware for executing the program. The control device and storage device execute the program, thereby realizing the functions described in each of the above embodiments.

[0060] The program may be non-transitory and may be recorded on one or more computer-readable recording media. The recording media may or may not be included in the device. In the latter case, the program may be supplied to the device via any wired or wireless transmission medium.

[0061] Furthermore, some or all of the functions of the control blocks can be realized by logic circuits. For example, an integrated circuit in which a logic circuit that functions as each of the control blocks is formed is also included in the scope of the present invention. In addition, the functions of the control blocks can also be realized by, for example, a quantum computer.

[0062] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. [Explanation of symbols]
