Description

The present invention relates to a data collection device, a data management device and a condition monitoring system.

As an environment-friendly power plant, a wind power plant equipped with a plurality of wind power generation devices is attracting attention. In each wind turbine generator, a blade that converts wind power into rotational force and a nacelle that stores the converter for converting the rotational force into electric power are arranged at a high place on a column (for example, several tens of meters above the ground). To. In each wind turbine generator, the condition of the wind turbine generator is monitored using the data collected from various sensors. Such condition monitoring is often performed from a remote location via a communication line or the like.

However, the wind power generator may be installed in mountainous areas, isolated islands, etc. where communication lines and the like cannot be used. The condition monitoring of such a wind power generation device is performed by using an offline data collection device that stores the measured data in the device. The offline data collection device is collected after data collection, and the measurement data is analyzed by a data analyst.

A data logger can be used as such a data collecting device. Japanese Unexamined Patent Publication No. 2001-21660 (Patent Document 1) discloses that position information is added to measured data by a data logger equipped with GPS (Global Positioning System).

Japanese Unexamined Patent Publication No. 2001-21660

Installation and collection of offline data collection equipment in wind turbines is an aerial work within the nacelle that requires qualifications. For this reason, the data analyst often asks the person in charge of maintenance of the wind power generation device for measurement.

In this case, the requested maintenance person needs to operate the data collection device to set the data collection device for the wind power generation device to be measured. Maintenance personnel are often unfamiliar with the data collection device, and it is assumed that the correct settings will not be applied to the data collection device due to operational mistakes or the like.

In order to prevent such an operation error, it is assumed that the data analyst applies the measurement settings for the target wind power generation device to the data collection device and hands the data collection device to the maintenance person. However, if the data analyst is far away, the man-hours and costs for sending the data collection device will increase.

In addition, even if the set data collection device is sent, if there are multiple wind power generation devices, the maintenance staff will install the data collection device on the wind power generation device that is not the wind power generation device that the maintenance staff originally wants to measure. It is assumed that it will start and the correct data cannot be obtained.

In this case, the data analyst will request the measurement again, which may cause disadvantages such as delay in abnormality detection, increased man-hours due to re-working, and loss of power generation opportunity for sensor installation. It was.

As shown in JP-A-2001-21660 (Patent Document 1), even when position information is added to the measured data, the data is sent to the data analyst after the measurement is completed, and the data analyst performs the position of the measured data. It is difficult to determine which wind power generator the measurement data is until the information is matched with the position information of the wind turbine generator. Therefore, it takes time to find out that the measurement was performed at the wrong place, and the measurement opportunity may be missed. When such a situation occurs, it may not be possible to obtain measurement data at the time required by the data analyst, and it may not be possible to detect an abnormality in the wind power generator.

Furthermore, even if the data can be measured correctly, if the data measured by the data collection device is saved in the data management analyzer in the wrong storage location, it will not be possible to know which wind power generator was used to measure the data. The discovery of anomalies may be delayed.

The present invention is for solving such a problem, and an object of the present invention is a data collecting device capable of reliably measuring data of a correct target, and data in a state in which the measurement target of measurement data is easy to understand.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings below, the same or corresponding parts will be given the same reference numbers, and the description will not be repeated.

FIG. 1 is a diagram for explaining a situation in which a condition monitoring system is installed. As an example of a place where a data acquisition device according to an embodiment of the present invention is installed, FIG. 1 shows a wind power plant 4 such as a mountainous area or an isolated island where wired and wireless communication lines cannot be used. The wind power plant 4 includes a plurality of wind power generation devices 10 (10-1 to 10-n) and a monitoring station 3. In this example, the case where the wind power plant 4 is equipped with n wind power generation devices 10 (n is a natural number) is shown.

Each wind power generator 10 converts wind power into rotational force by a blade and generates electricity by a generator. Each wind power generation device 10 is arranged at a distance of, for example, several hundred meters from the adjacent wind power generation device 10.

In each wind power generator 10, a blade that converts wind power into rotational force and a nacelle that stores a speed increaser, a generator, etc. for converting the rotational force into electric power are provided at a high place (for example, a column) on a tower (strut). It will be installed several tens of meters above the ground. The blades and nacelles are rotatably supported on the tower and the yaw angle is controlled according to the wind direction.

An analyst at a distant data analysis center 1 sends a recording medium 2 (for example, a memory card using a non-volatile memory) on which the position of an object and measurement settings, which will be described later, are recorded to the monitoring post 3. A data collection device and various sensors for measurement are stored in the monitoring post 3.

At the request of the analyst, the maintenance person sets the recording medium 2 in the data collection device and heads for one of the wind power generation devices 10 to be measured.

The wind turbine generator 10 includes a tower 70 and a nacelle 90. The maintenance person installs the data acquisition device and the sensor in the nacelle 90.

In the nacelle 90, various sensors (vibration sensor, temperature sensor, etc.) for detecting the state of the main bearing supporting the spindle for transmitting the rotational force, the speed increaser, and the like are installed. Various data for monitoring the state of the wind power generation device 10 are collected by various sensors.

Vibration data is one of the measurement data of the wind power generator 10. As shown in FIG. 2, the nacelle 90 vibrates in a strong wind or the like, and this vibration is measured by a sensor.

FIG. 3 is a diagram showing a configuration of a wind power generation device. The wind power generation device 10 shown in FIG. 3 corresponds to each of the wind power generation devices 10-1 to 10-n in FIG. With reference to FIG. 3, the wind turbine generator 10 includes a spindle 22, a blade 30, a speed increaser 40, a generator 50, a main bearing 60, and a data acquisition device 100. The speed increaser 40, the generator 50, the main bearing 60 and the data acquisition device 100 are housed in the nacelle 90, and the nacelle 90 is supported by the tower 70.

The spindle 22 enters the nacelle 90 from the rotor head 20 and is connected to the input shaft of the speed increaser 40, and is rotatably supported by the spindle 60. Then, the main shaft 22 transmits the rotational torque generated by the blade 30 that has received the wind power to the input shaft of the speed increaser 40. The blade 30 is provided at the tip of the spindle 22 and converts wind power into rotational torque.

The main bearing 60 is fixed in the nacelle 90 and rotatably supports the main shaft 22. The main bearing 60 is composed of rolling bearings, for example, self-aligning roller bearings, tapered roller bearings, cylindrical roller bearings, ball bearings and the like. These bearings may be of single row or double row.

The speed increaser 40 is provided between the spindle 22 and the generator 50, and increases the rotational speed of the spindle 22 and outputs the speed to the generator 50. As an example, the speed increaser 40 is configured by a gear speed increase mechanism including a planetary gear, an intermediate shaft, a high speed shaft, and the like. Although not particularly shown, a plurality of bearings for rotatably supporting a plurality of shafts are also provided in the speed increaser 40. The generator 50 is connected to the output shaft of the speed increaser 40 and generates electricity by the rotational torque received from the speed increaser 40. The generator 50 is composed of, for example, an induction generator. A bearing that rotatably supports the rotor is also provided in the generator 50.

A sensor 81 for detecting vibration and a sensor 82 for detecting temperature are installed in order to collect data indicating the state of the wind power generation device 10. The installation locations of the sensors 81 and 82 are examples, and the installation locations may be changed or the number of installations may be increased as necessary. Further, the temperature sensor and the vibration sensor are examples, and sensors for detecting other physical quantities such as humidity and atmospheric pressure may be added.

FIG. 4 is a diagram showing a configuration of a condition monitoring system including a data collection device and a data management device.

With reference to FIG. 4, the condition monitoring system 11 includes a data collecting device 100 and a data management device 200. The data management device 200 is located in the data analysis center 1 of FIG. 1 and is operated by an analyst. The data collection device 100 is arranged at the monitoring post 3 in FIG. 1, and is installed in any of the wind power generation devices 10-1 to 10-n by a maintenance person as needed.

The data collecting device 100 includes a GPS receiver 105, a first media mounting unit 103 that mounts a recording medium 2 on which position information of a measurement target is recorded, and a first control device 101 that controls to measure the measurement target. Be prepared.

In the first control device 101, the first position indicated by the position information of the data collecting device 100 detected by the GPS receiver 105 is the position information of the measurement target read from the recording medium 2 mounted on the first media mounting unit 103. If it is outside a certain range from the second position shown, the measurement operation is not executed. On the other hand, the first control device 101 executes the measurement operation when the first position is within a certain range from the second position. This fixed range is appropriately set according to the position detection accuracy of the GPS receiver 105 and the distance between the adjacent wind power generation devices 10, but can be, for example, within 100 m.

By turning on the power switch or the like, the setting data indicating the measurement conditions and the like written in advance on the recording medium 2 is automatically read into the data collecting device 100 and applied to the data collecting device 100. However, before applying the setting data, the position information is confirmed as described above, and the error is displayed on the error display unit 104 before the measurement is executed at the wrong place. In this way, it is possible to prevent the measurement from being started at the wrong place.

Preferably, the data acquisition device 100 further includes terminals 106, 107 to connect the sensors 81, 82. The first control device 101 executes an operation of recording the information indicated by the signals detected by the sensors 81 and 82 connected to the terminals 106 and 107 on the recording medium 2 as a measurement operation.

The sensors 81 and 82 output, for example, a raw waveform of a signal representing a vibration waveform to the data acquisition device 100. The first control device 101 of the data collection device 100 collects the raw waveform data of the vibration sensor in the memory 112. The first control device 101 calculates various diagnostic values from the raw waveform data. The raw waveform and the calculated value are stored inside the recording medium 2 set in the data acquisition device 100.

However, when the measurement setting data for the measurement target read from the recording medium 2 mounted on the first media mounting unit 103 does not correspond to the sensors 81 and 82 connected to the terminals 106 and 107, the first control device 101 , Do not perform measurement operation. On the other hand, in the first control device 101, when the measurement setting data for the measurement target read from the recording medium 2 mounted on the first media mounting unit 103 corresponds to the sensors 81 and 82 connected to the terminals 106 and 107. Executes the measurement operation according to the measurement conditions indicated by the measurement setting data.

By doing so, it is possible to prevent the measurement from being performed with the wrong sensor connected.

The data collected by the data collecting device 100 is managed by the data management device 200. The data management device 200 has a second media mounting unit 203 for mounting the recording media 2 on which the data collected by the data collecting device 100 is recorded, and data recorded on the recording media mounted on the second media mounting unit 203. A measurement data storage unit 220 for storing the data and a second control device 201 for controlling the data storage operation for the measurement data storage unit 220 are provided.

Specific information (such as an ID of the device) that identifies the measurement target is recorded on the recording medium 2 together with the measurement data of the measurement target. The second control device 201 creates data folders 221 to 223 corresponding to the specific information of the first to third measurement targets recorded on the recording medium 2 mounted on the second media mounting unit 203, and the data folders 221 to 221. The measurement data corresponding to 223 is automatically stored.

In this way, the measurement data is stored in a state in which folders are automatically created and organized. Therefore, the measurement data is stored in the measurement data storage unit 220 in an easy-to-understand state divided for each measurement target without the analyst creating a complicated folder.

FIG. 5 is a flowchart showing a data registration process on the recording medium in the data management device. With reference to FIGS. 4 and 5, first, in step S101, the second control device 201 of the data management device 200 has the ID and position of the wind power generation device to be measured according to the input contents of the analyst from the input device 204. Performs processing for accepting registration of information and measurement setting information.

Subsequently, in step S102, the second control device 201 has registered ID, position information, and measurement setting information of the wind power generation device to be measured with respect to the recording medium 2 mounted on the second media mounting unit 203. Is executed in advance before the measurement, and the process is completed in step S103. At this time, it is preferable to enable registration corresponding to a plurality of measurement targets.

FIG. 6 is a flowchart showing a data collection target determination process in the data collection device. The processing of this flowchart is executed in response to a maintenance person turning on the power switch of the data collection device 100 at the measurement site.

With reference to FIGS. 4 and 6, in step S11, the first control device 101 determines whether or not the recording medium 2 is inserted into the first media mounting unit 103. When the recording medium 2 is inserted into the first media mounting unit 103 (YES in S11), the first control device 101 reads the registration data previously written in the recording medium 2 in step S12.

Subsequently, in step S13, the first control device 101 writes the position information received by the GPS receiver 105 in the data collection device 100 and the recording medium 2 in a state where the recording medium 2 is set in the data collection device 100. It is confirmed that the data collecting device 100 is installed in the wind power generation device to be measured by comparing with the position information of the measurement target.

Specifically, the first control device 101 measures the first position indicated by the position information of the data collecting device 100 detected by the GPS receiver 105, which is read from the recording medium 2 mounted on the first media mounting unit 103. Whether or not it is installed in the correct measurement target wind power generator is determined based on whether or not it is within a certain range (for example, within 100 m) from the second position indicated by the target position information.

Next, in step S14, the first control device 101 determines whether the contents described as the channels used in the measurement setting file of the recording medium 2 match the sensor connection on the data collection device 100 side with the voltages of the terminals 106 and 107. Check and confirm. For example, by connecting a pull-up resistor or the like to the terminals 106 and 107, the voltage of the terminals 106 and 107 when the sensor is not connected can be made different from the voltage when the sensor is connected.

When the connection of the sensor matches the contents of the measurement setting file (YES in S14), the first control device 101 automatically applies the contents of the setting file to the data collection device 100.

Then, in step S16, the first control device 101 displays to the error display unit 104 that it is normal in step S16, and executes data collection in step S17. At this time, the measurement data in the data collection device is stored in the recording medium set in the data collection device.

On the other hand, if the recording media 2 is not inserted into the first media mounting portion 103 (NO in S11), or if there is a mismatch in the position or sensor connection in the confirmation (NO in S13 or S14), in step S19, the first step is made. 1 The control device 101 displays a display on the error display unit 104 to warn the maintenance person so that the measurement cannot be started.

FIG. 7 is a flowchart showing details of the data collection process executed in S17 of FIG. With reference to FIGS. 4 and 7, in step S51, the first control device 101 determines whether or not the measurement start condition specified in the setting information applied in step S15 of FIG. 6 is satisfied. The measurement start condition is satisfied, for example, when the rotation speed of the spindle exceeds a certain rotation speed, when the amount of power generated by the generator exceeds a certain amount of power generation, or when a designated date and time arrives.

When the measurement start condition is not satisfied (NO in S51), the first control device 101 repeats the process of step S51 to put the data collection in the standby state until the condition is satisfied. When the measurement start condition is satisfied (YES in S51), in step S52, the first control device 101 acquires signals such as vibration and temperature detected by the sensors 81 and 82, and digitally uses an A / D converter (not shown). After converting the signal, the measurement data is written to the recording medium 2 in step S53. At this time, filter processing, frequency analysis processing, or the like may be performed as necessary.

Subsequently, in step S54, the first control device 101 determines whether or not the measurement stop condition specified in the setting information applied in step S15 of FIG. 6 is satisfied. The measurement stop condition is recorded, for example, when a predetermined time has passed from the start of measurement, when the rotation speed of the spindle becomes a certain rotation speed or less, or when the power generation amount of the generator becomes a certain power generation amount or less. This is established when the free space of the media 2 is insufficient. If the measurement stop condition is not satisfied (NO in S54), the process returns to step S51 again, and the measurement is repeated. On the other hand, when the measurement stop condition is satisfied (YES in S54), the data collection process ends in step S55.

FIG. 8 is a flowchart showing a process of storing data from a recording medium in the data management device.

With reference to FIGS. 4 and 8, after the measurement is completed, the recording medium 2 is set in the second media mounting unit 203 of the data management device 200, and the measurement data is read by the application program executed by the second control device 201. ..

At that time, first, in step S111, the second control device 201 reads the ID of the wind power generation device to be measured written on the recording medium 2. As a result, the measured wind power generation device is determined, and in step S112, the second control device 201 automatically stores the data folders 221 to 223 for each wind power generation device in the measurement data storage unit when there is no corresponding full folder. Create at 220. The measurement data storage unit 220 is a storage device having a storage capacity larger than that of the recording medium 2, such as a hard disk.

Subsequently, in step S113, the second control device 201 distributes and stores the measurement data such as vibration and temperature of the wind power generation device to be measured written in the recording medium 2 in the corresponding data folder, and in step S114. End the data reading process.

As described above, according to the condition monitoring system according to the present embodiment, in the condition monitoring system for the offline wind power generation device, the analyst sets the position information of the wind power generation device to be measured and the setting used for the measurement. It is stored in the recording medium 2 in advance. The maintenance person sets the recording medium 2 in the data collection device 100. In the data acquisition device 100, the first control device 101 is a wind power generation device to be automatically measured by comparing the position information stored in the recording medium 2 with the position information detected by the GPS receiver 105. And confirm that the sensor is connected according to the measurement settings. When these can be confirmed, the first control device 101 applies the measurement setting file in the recording medium 2 to the data collection device 100. If these cannot be confirmed, the first control device 101 displays an error message without starting the measurement.

Therefore, according to the condition monitoring system of the present embodiment, it is possible to reliably measure the data in the wind power generation device to be measured in the state monitoring system for the offline wind power generation device.

Further, when the data management device 200 reads out the measured data in the recording medium 2, the data management device 200 automatically confirms the ID of the wind power generation device to be measured in the media, and generates and saves the corresponding data folder.

Therefore, according to the condition monitoring system of the present embodiment, the data is stored in an easy-to-understand manner in the condition monitoring system for the offline wind power generation device, so that when the analyst handles the measurement data, a mistake such as a mistake in the data is made. Can be prevented.
