[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-237547 Summary of the Invention [Problem to be solved by the invention]

[0005] While the basic requirements for long-period vibration sensing devices are stipulated by law, the algorithms used to predict vibration are not. Each manufacturer independently develops their own algorithms. Furthermore, even within the same building, elevator specifications, such as the overall height of elevator shafts, vary from bank to bank. Therefore, even if the same algorithm is used, parameter settings must be different for each bank. Conventional technologies such as those described in Patent Document 1 cannot accommodate multiple types of elevators with a single long-period vibration sensing device; instead, multiple long-period vibration sensing devices must be installed for each type of elevator.

[0006] The present disclosure is intended to solve the above-mentioned problems. An object of the present disclosure is to enable a single long-period vibration sensing device to be used for multiple types of elevators. [Means for solving the problem]

[0007] The long-period vibration sensing device according to the present disclosure is installed in a building equipped with multiple types of elevators, and outputs a sensing signal when it detects long-period vibration. The long-period vibration sensing device according to the present disclosure includes a vibration detection sensor that detects long-period vibration, and a control unit that performs a calculation using the long-period vibration value detected by the vibration detection sensor as an input value and determines whether or not to output the sensing signal based on the calculation result. The control unit performs the calculation using multiple algorithms and parameter settings stored in a data storage means that stores the algorithms and parameter settings corresponding to each of the multiple types of elevators, and determines whether or not to output the sensing signal for each of the multiple types of elevators based on the calculation result.

[0010] Hereinafter, embodiments of a long-period vibration sensing device according to the present disclosure will be described with reference to the accompanying drawings. The same reference numerals in the drawings indicate the same or corresponding parts. In this disclosure, redundant explanations will be appropriately simplified or omitted. Note that the present disclosure is not limited to the embodiments described below, and may include all combinations and modifications of the configurations disclosed in the following embodiments.

[0011] Embodiment 1 FIG. 1 is a diagram showing the configuration of a long-period vibration sensing device 100 according to a first embodiment. The long-period vibration sensing device 100 according to this embodiment is installed in a building equipped with multiple types of elevators. The long-period vibration sensing device 100 is a device that outputs a sensing signal when it senses long-period vibration. As an example, the long-period vibration sensing device 100 is installed at the top of a building so that it can easily sense long-period vibration.

[0012] As shown in Fig. 1, long-period vibration sensing device 100 includes a vibration detection sensor 1 that detects long-period vibrations. Long-period vibration sensing device 100 also includes a control unit 2 that performs calculations using a predetermined algorithm with the value of the long-period vibration detected by vibration detection sensor 1 as an input value. Control unit 2 determines whether or not a detection signal needs to be output based on the calculation result. Long-period vibration sensing device 100 also includes a signal transmission unit 3 that outputs a detection signal based on the determination result by control unit 2.

[0013] As shown in FIG. 1, the long-period vibration sensing device 100 of this embodiment has an algorithm storage unit 4 and a parameter storage unit 5 as examples of data storage means. The algorithm storage unit 4 can store a plurality of calculation algorithms. The parameter storage unit 5 can store a plurality of parameter settings.

[0014] Each manufacturer that installs elevators in a building where the long-period vibration sensing device 100 is installed stores its own calculation algorithm in the algorithm storage unit 4. In addition, each manufacturer stores the parameter settings for each elevator bank in the parameter storage unit 5.

[0015] The algorithm storage unit 4 and parameter storage unit 5, which are examples of data storage means, may be external storage devices such as SD cards. When initializing algorithms and parameters, improving algorithms, or changing parameter settings, it is preferable to prevent other companies from viewing each manufacturer's own algorithms and parameter settings, which represent their own know-how. Therefore, it is preferable to use encrypted file formats for the setting files stored in the algorithm storage unit 4 and parameter storage unit 5, rather than text files. This makes the setting files unreadable even if they are passed to other companies, ensuring confidentiality.

[0016] The long-period vibration sensing device 100 may have an interface that can be directly connected to a setting device such as a laptop computer in order to set the algorithms stored in the algorithm storage unit 4 and the parameters stored in the parameter storage unit 5. In this case, it is preferable that the application for setting the algorithms and parameters requires an account for each manufacturer and cannot access different accounts. This prevents information from being accessed by anyone other than the manufacturer, ensuring confidentiality.

[0017] The long-period vibration sensing device 100 may have an interface that can be connected to a setting device such as a client computer via a network, in order to remotely set the algorithms stored in the algorithm storage unit 4 and the parameters stored in the parameter storage unit 5. In this case, it is preferable that the web application for setting the algorithms and parameters requires an account for each manufacturer and cannot access different accounts. This prevents information from being accessed by anyone other than the manufacturer, ensuring confidentiality.

[0018] When long-period vibration occurs in a building in which the long-period vibration sensing device 100 is installed, the vibration detection sensor 1 detects the magnitude of the vibration. The control unit 2 performs calculations using the value of the long-period vibration detected by the vibration detection sensor 1 as an input value. At this time, the control unit 2 performs calculations using multiple algorithms stored in the algorithm storage unit 4 and multiple parameter settings stored in the parameter storage unit 5. The control unit 2 determines whether or not to output a detection signal for each of multiple types of elevators based on the calculation results. If the control unit 2 determines that a detection signal needs to be output, the signal transmission unit 3 transmits the detection signal. When the signal transmission unit 3 transmits the detection signal, processing such as suspending operation of the elevator that received the detection signal is performed. As such, according to this embodiment, a single long-period vibration sensing device 100 can be used to accommodate multiple types of elevators.

[0019] FIG. 2 is a diagram illustrating a first operation example of the long-period vibration sensing device 100 according to the first embodiment. As described above, when the long-period vibration sensing device 100 detects long-period vibration, it performs calculations using the algorithms of each company and the parameter settings of each bank, determines whether or not to output a detection signal based on the calculation results, and outputs a detection signal for elevators for which it is determined that output is required. In the operation example of FIG. 2, detection signals for multiple types of elevators are sent together to the building's control room 101. The control room 101 is generally also referred to as a "central control room" or "control center." In the operation example of FIG. 2, after the detection signals for multiple types of elevators are sent together to the control room 101, the control room 101 issues a control signal to the elevator control unit of the target bank.

[0020] Although Fig. 2 shows an example in which it is necessary to output a detection signal for elevators in only one of multiple banks, even if it is necessary to output a detection signal for elevators in multiple banks, the detection signals are transmitted together to control room 101. In the example shown in Fig. 2, the status of multiple types of elevators can be managed in a unified manner in control room 101, and the number of communication lines and communication modules for transmitting detection signals can be reduced.

[0021] FIG. 3 is a diagram showing a second operation example of the long-period vibration sensing device 100 of the first embodiment. In the operation example of FIG. 3, the long-period vibration sensing device 100 directly transmits a sensing signal to the elevator control unit of the corresponding bank. Most conventional long-period vibration sensing devices for elevators are directly connected to the elevator control unit. The example of FIG. 3 is suitable for replacing such conventional systems. Note that either a wired or wireless connection can be used as the method for connecting the long-period vibration sensing device 100 and the elevator control unit.

[0022] Conventional long-period vibration sensing devices required the installation of multiple units to accommodate multiple types of elevators. For example, if a building's vibration control device is changed, the algorithm and parameter settings for determining whether or not to output a sensing signal must be changed. Furthermore, if the building management department requests a review of the settings to prevent unnecessary elevator outages, the algorithm and parameter settings for determining whether or not to output a sensing signal must also be revised. When multiple long-period vibration sensing devices are installed, changing the settings in cases such as those described above requires a great deal of effort. With this embodiment, a single long-period vibration sensing device 100 can accommodate multiple types of elevators, thereby reducing the effort required for changing the settings.

[0023] There are individual differences among sensors that detect long-period vibrations, such as vibration detection sensor 1. When multiple long-period vibration detection devices are installed, even if the same algorithm and parameter settings are used, there is variation in whether or not the detection signal is output. Furthermore, in practice, it is necessary to use algorithms unique to each company and parameter settings unique to each bank, which results in even greater variation.

[0024] For example, when vibrations near the operating threshold occur in a building, the output of a detection signal from each detection device may differ. For example, in a building that houses elevators from multiple manufacturers, when long-period vibrations occur, some elevators enter a pause state while others do not.

[0025] When considering individual differences in sensors, it is possible to adopt a setting that makes it easier to output a detection signal to reduce the likelihood of damage. This increases the likelihood that the elevator will not operate while a long object is caught. However, at the same time, it also increases the likelihood that the elevator will enter a stopped state even when no long object is actually caught.

[0026] According to this embodiment, one vibration detection sensor 1 included in one long-period vibration sensing device 100 can be used for a plurality of types of elevators, and can deal with the above-mentioned variations. [Explanation of symbols]
