[0004] [Patent Document 1] JP 2013-237547 A Summary of the Invention [Problem to be solved by the invention]

[0005] Although the basic required specifications for a long-period vibration sensor are stipulated by law, there are no stipulations regarding algorithms for predicting vibration. Each manufacturer independently develops such algorithms. Furthermore, even in the same building, elevator specifications such as the total height of the elevator shaft vary from bank to bank, so that even if the same algorithm is used, parameter settings must be different for each bank. In the conventional technology such as that in Patent Document 1, one long-period vibration sensor cannot be used for multiple types of elevators, and multiple long-period vibration sensors must be installed according to the type of elevator.

[Diagram 3] 6A to 6C are diagrams illustrating a second operation example of the long-period vibration sensing device of the first embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment 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 each drawing indicate the same or corresponding parts. In this disclosure, duplicated descriptions 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 in which multiple types of elevators are installed. The long-period vibration sensing device 100 is a device that outputs a sensing signal when it detects long-period vibration. As an example, the long-period vibration sensing device 100 is installed at the top of a building so that it is easy to detect 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 vibration. The 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 the vibration detection sensor 1 as an input value. The control unit 2 determines whether or not to output a detection signal depending on the calculation result. The long-period vibration sensing device 100 includes a signal transmission unit 3 that outputs a detection signal depending on the determination result by the control unit 2.

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

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

[0015] As the algorithm storage unit 4 and the parameter storage unit 5, which are examples of data storage means, external storage devices such as SD cards may be used. When initializing algorithms and parameters, improving algorithms, or changing parameter settings, it is preferable to prevent other companies from viewing the algorithms and parameter settings, which are the know-how of each manufacturer. Therefore, it is preferable to use an encrypted file format rather than a text file format for the setting files stored in the algorithm storage unit 4 and the parameter storage unit 5. This makes it impossible to decrypt the setting files 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 referenced by any company 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 referenced by any manufacturer other than the manufacturer, ensuring confidentiality.

[0018] When a 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 a calculation 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 the calculation using a plurality of algorithms stored in the algorithm storage unit 4 and a plurality of parameter settings stored in the parameter storage unit 5. The control unit 2 determines whether or not it is necessary to output a detection signal for each of the plurality of types of elevators according to the calculation result. If the control unit 2 determines that it is necessary to output a detection signal, the signal transmission unit 3 transmits the detection signal. When the detection signal is transmitted from the signal transmission unit 3, a process such as suspending the operation of the elevator that received the detection signal is performed. In this way, according to this embodiment, a single long-period vibration sensing device 100 can be used for a plurality of types of elevators.

[0019] FIG. 2 is a diagram showing a first operation example of the long-period vibration sensing device 100 of the first embodiment. As described above, when the long-period vibration sensing device 100 detects a long-period vibration, it performs a calculation using the algorithm of each company and the parameter setting of each bank, judges whether or not to output a detection signal according to the calculation result, and outputs a detection signal for an elevator that is judged to be output. In the operation example of FIG. 2, the detection signals for multiple types of elevators are once sent together to the management room 101 of the building. The management room 101 is generally also called the "central management room" or "management center". In the operation example of FIG. 2, the detection signals for multiple types of elevators are sent together to the management room 101, and then a control signal is issued from the management room 101 to the control unit of the elevator of the target bank.

[0020] Although Fig. 2 shows an example in which it has become necessary to output a detection signal for elevators in only one of multiple banks, even if it has become necessary to output a detection signal for elevators in multiple banks, the detection signals are sent collectively to management room 101. In the example shown in Fig. 2, management room 101 can centrally manage the status of multiple types of elevators, and the number of communication lines and communication modules for sending 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 of the long-period vibration sensing devices of conventional elevators are directly connected to the elevator control unit. The example of Fig. 3 is suitable for replacing such conventional methods. Note that either a wired connection or a wireless connection can be used as a method for connecting the long-period vibration sensing device 100 and the elevator control unit.

[0022] Conventionally, multiple long-period vibration sensing devices must be installed to accommodate multiple types of elevators. For example, when the vibration control device of a building is changed, it is necessary to change the algorithm and parameter settings for determining whether or not to output a sensing signal. In addition, when a request is received from the building management department to review the settings to prevent unnecessary elevator outages, it is necessary to modify the algorithm and parameter settings for determining whether or not to output a sensing signal. When multiple long-period vibration sensing devices are installed, it takes a lot of effort to change the settings in the above cases. In this embodiment, one long-period vibration sensing device 100 can accommodate multiple types of elevators, so the effort required for changing the settings can be reduced.

[0023] There are individual differences in sensors that detect long-period vibrations, such as the 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 for each company and parameter settings for 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 may or may not be determined by the detection device. For example, in a building that contains elevators from multiple manufacturers, when long-period vibrations occur, some elevators go into a pause state and others do not.

[0025] When considering individual differences in sensors, it is possible to adopt settings that make it easier to output a detection signal so that damage is less likely to occur. This increases the likelihood that, for example, the elevator will be prevented from operating 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 in a situation where a long object is not 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]
