Description

  The present invention relates to an equipment maintenance apparatus, equipment maintenance system, equipment maintenance method, and equipment maintenance program.

  Conventionally, it is known to introduce state monitoring and maintenance technology into various power generation facilities and power facilities such as wind power plants, solar power plants, hydroelectric power plants, thermal power plants, and substations. Status monitoring and maintenance technology measures the status of power generation equipment and power equipment installed in power equipment on a regular basis using sensors such as vibration sensors and strain sensors. This is a technology that protects the equipment by detecting the harbinger of the occurrence of a fault. A device state signal representing the state of the device measured by the sensor is transmitted to, for example, an equipment maintenance apparatus that performs maintenance by centrally monitoring equipment of a plurality of equipment. The equipment maintenance device detects the foresight of the failure or abnormality of the equipment of each equipment based on the equipment status signal received from each equipment, and provides the corresponding equipment together with countermeasures to maintain the equipment.

  For example, in a wind power generation facility, it is necessary to maintain blades and power generators for wind power generation. However, since maintenance technology such as visual inspection requires a lot of time and cost, it is effective to use state monitoring and maintenance technology. In the state monitoring and maintenance technology of a wind power generation facility, for example, an optical fiber temperature / vibration sensor is embedded in a blade, and measurement signals of the blade temperature and vibration are transmitted to the facility maintenance device via a communication network. In the state monitoring and maintenance technology for wind power generation equipment, for example, various sensors such as a vibration sensor, a strain sensor, and a camera are installed in the power generation apparatus, and measurement signals of the various sensors are transmitted to the equipment maintenance apparatus via a communication network.

  The equipment maintenance apparatus is provided with a database in which past maintenance histories of the blades and the power generation apparatus are stored in correspondence with measurement signals of various sensors. The equipment maintenance apparatus monitors the state of soundness such as damage to the blades and the power generation apparatus and material deterioration by comparing the received measurement signals of various sensors with a database. For example, if the equipment maintenance device detects a warning of the occurrence of damage to the wing, for example, the maintenance information may include a recommendation that the wing may be damaged in the near future and that the wing parts should be replaced as a countermeasure. provide.

  By the way, in the conventional state monitoring and maintenance technology, no consideration is given to improving the recovery rate of the value from the facility for the provision of maintenance information.

  In other words, in recent years, maintenance services have been examined in Japan for power generation equipment constructed overseas, power generation equipment for power equipment, and status monitoring and maintenance of power equipment in Japan, but maintenance information is provided for overseas power generation equipment and power equipment. The payment of consideration for is likely to be delayed. In addition, not only overseas power generation facilities and power facilities, but also domestic wind power facilities, solar power generation facilities, and hydropower generation facilities, in the same way, pay for the provision of maintenance information. There is a possibility that it is easy to get stuck and it is not possible to sufficiently collect the consideration.

  This invention is made | formed in view of the above, Comprising: Let it be a subject to improve the collection | recovery rate of the value from the installation with respect to provision of maintenance information.

  In order to solve the above-described problem, the equipment maintenance apparatus of the present invention transmits a device status signal obtained based on a measurement signal of a sensor that measures the status of a maintenance target device from a facility having the maintenance target device via a communication network. Corresponding to each of a plurality of types of equipment status signals, maintenance information related to maintenance target equipment, and conditions relating to the maintenance level of the equipment for providing this maintenance information to the equipment. The maintenance level that is set in advance for the equipment according to the amount paid by the equipment for the provision of maintenance information, corresponding to the equipment information signal received by the status signal receiver and the equipment status signal received by the status signal receiver. Maintenance information that reads the maintenance information that satisfies the maintenance level requirements from the maintenance information database and the maintenance information that is read by the maintenance information calculation unit And a maintenance information transmission unit that transmits to the facility via Ttowaku.

  That is, the maintenance information calculation unit provides the maintenance information to the facility when the maintenance level set in advance in the facility satisfies the condition for providing the maintenance information. According to this, the equipment maintenance device does not provide the equipment unconditionally with the maintenance information corresponding to the equipment status signal received by the status signal receiver, but the amount that the equipment has paid in the past as compensation for the maintenance information. Accordingly, a difference can be made in the maintenance service for each facility. For example, for equipment that does not pay enough for the maintenance service, as a minimum necessary maintenance service, there is a risk that the equipment may be damaged in the near future, so an emergency stop of operation should be made . On the other hand, for facilities that are paid sufficiently for maintenance services, it is recommended that parts should be replaced systematically in anticipation of the possibility of damage in the middle to long If so, provide measures to improve power generation efficiency. As a result, according to the present invention, it is possible to give the facility an incentive for payment of the compensation for provision of maintenance information, and it is considered that the recovery rate of the compensation from the facility for provision of maintenance information can be improved.

  In addition, the maintenance level of the equipment maintenance equipment is set in stages according to the payment amount input unit that inputs the amount paid by the equipment as the compensation for the provision of maintenance information and the amount that the equipment pays for the provision of the maintenance information. And a maintenance level calculation unit that reads the maintenance level corresponding to the payment amount input by the payment amount input unit from the maintenance level calculation database and sets the maintenance level of the facility.

  According to this, if the amount paid for the provision of maintenance information by the facility is entered in the payment amount input section, the maintenance level of the facility is automatically set by the maintenance level calculation section. Setting or resetting operations can be simplified.

  Moreover, the equipment maintenance system of this invention is provided with the equipment which has the apparatus of a maintenance object, and the equipment maintenance apparatus which provides the equipment with the maintenance information according to the state of an apparatus. The equipment converts the measurement signal of the sensor that measures the state of the device by, for example, Fourier transform, and the converted signal has a peak output that is within a preset frequency band equivalent range and larger than the preset signal level. In the case of occurrence, a status signal transmission unit is provided that transmits the frequency equivalent band and the output signal level as a device status signal to the equipment maintenance apparatus via the communication network.

  According to this, compared with the case where the measurement signal measured by the sensor is steadily transmitted to the equipment maintenance apparatus as it is, the communication amount of the signal can be reduced. Moreover, since the monitoring staff of the equipment maintenance apparatus has only to wait for the arrival of the equipment status signal and start the monitoring activity, it is possible to centrally monitor the equipment status of the plurality of power generation equipment with a small number of monitoring staff.

  ADVANTAGE OF THE INVENTION According to this invention, the collection | recovery rate of the value from the installation with respect to provision of maintenance information can be improved.

  Embodiments of an equipment maintenance apparatus, equipment maintenance system, equipment maintenance method, and equipment maintenance program disclosed in the present application will be described below in detail with reference to the drawings. The disclosed technology is not limited by this embodiment.

  FIG. 1 is a diagram showing an overall configuration of an equipment maintenance system. The facility maintenance system 100 includes a plurality of wind power generation facilities 200-1 to 200-n (n is a natural number of 2 or more), and facility maintenance connected to the wind power generation facilities 200-1 to 200-n via a communication network 300. Device 400.

  Each of the wind power generation facilities 200-1 is provided with a windmill 202 having wind power generation blades 201 and a power generation device 204 that obtains electric energy from mechanical energy generated by the rotation of the windmill 202. In addition, each of the wind power generation facilities 200-1 to 200-n includes a control device 206 that controls the amount of power generation in the power generation device 204, and a signal that transmits and receives various signals to and from the facility maintenance device 400 via the communication network 300. A transmission / reception unit 208 is provided.

  The blade 201 is provided with an optical fiber temperature / vibration sensor 210 that is a sensor for measuring the state of the blade 201. Further, the power generation device 204 is provided with a strain sensor 212 that is a sensor for measuring the state of the power generation device 204. The power generation amount in the power generation device 204, the measurement signal measured in time series by the optical fiber temperature / vibration sensor 210, and the measurement signal measured in time series by the strain sensor 212 are sent to the signal transmission / reception unit 208. Since the wind power generation facilities 200-2 to 200-n have the same configuration as the wind power generation facility 200-1, description thereof is omitted.

  FIG. 2 is a diagram illustrating an installation example of the optical fiber temperature / vibration sensor 210 and the strain sensor 212. As shown in FIG. 2, the optical fiber temperature / vibration sensor 210 is embedded in each blade 201. The measurement signal measured by the optical fiber temperature / vibration sensor 210 is sent to the signal transmission / reception unit 208 via the signal line 214. The strain sensor 212 is attached to the power generation device 204. The measurement signal measured by the strain sensor 212 is sent to the signal transmission / reception unit 208 via the signal line 214. In addition, although the present Example showed the example which provides the distortion sensor 212 in the electric power generating apparatus 204, it is not restricted to this, A sensor, such as a vibration sensor or a camera, can also be provided in the electric power generating apparatus 204.

  FIG. 3 is a diagram illustrating an example of a device status signal transmitted from the signal transmission / reception unit 208 to the wind power generation equipment 200-1 to 200-n. The signal transmission / reception unit 208 standardizes the measurement signals of the optical fiber temperature / vibration sensor 210 and the strain sensor 212 into digital standard management signals. Specifically, as shown in FIG. 3, the signal transmission / reception unit 208 obtains a Fourier signal 218 by performing Fourier transform on the time-series measurement signals 216 of the optical fiber temperature / vibration sensor 210 and the strain sensor 212.

  The signal transmitting / receiving unit 208 uses the Fourier signal 218 to search for a signal in a frequency band characteristic of, for example, damage. That is, the signal transmission / reception unit 208 monitors whether or not a peak output greater than the preset signal level 222 occurs in the Fourier signal 218 within the preset frequency band 220. When a peak output within the frequency band 220 and greater than the signal level 222 is generated in the Fourier signal 218, the signal transmission / reception unit 208 uses the frequency band and the output signal level as a device state signal representing the state of the device. The signal transmission / reception unit 208 transmits a device status signal to the equipment maintenance apparatus 400 via the communication network 300.

  When the peak output of the Fourier signal 218 within the frequency band 220 and greater than the signal level 222 is generated in the Fourier signal 218, the signal transmission / reception unit 208 uses the generation time, frequency band, and time change pattern of the signal as the device status signal. You can also In addition, when a camera is installed as a sensor for measuring the state of the power generation device 204, the signal transmission / reception unit 208 performs image analysis on the image signal captured by the camera, and outputs a device state signal when a characteristic change occurs. It can be transmitted to the equipment maintenance device 400. Specifically, when a characteristic change occurs in the image signal captured by the camera, the signal transmission / reception unit 208 outputs a digital signal such as the characteristic change occurrence time, the change pattern, and image information at the corresponding time. Can be transmitted to the equipment maintenance apparatus 400 as a device status signal.

  Returning to the description of FIG. 1, the facility maintenance apparatus 400 receives a device status signal transmitted from each of the signal transmission / reception units 208 of the wind power generation facilities 200-1 to 200-n via the communication network 300. 402. In addition, the facility maintenance apparatus 400 includes a payment amount input unit 404 that inputs an amount paid by each of the wind power generation facilities 200-1 to 200-n as a price for the maintenance service of the blades 201 and the power generation apparatus 204. The payment amount input unit 404 can be configured as a reception unit that receives, for example, the amount paid by the wind power generation facilities 200-1 to 200-n via the communication network 300, or is configured as an input unit that is manually input. You can also

  The facility maintenance device 400 includes a facility DB (Data Base) 406 for managing various types of information on the wind power generation facilities 200-1 to 200-n, and a maintenance level calculation DB 408 for setting the maintenance level of each facility. Have Moreover, the equipment maintenance apparatus 400 has a maintenance information DB 410 for obtaining maintenance information of each equipment. In addition, the facility maintenance apparatus 400 includes a maintenance level calculation unit 412 that sets the maintenance level of each facility using the facility DB 406 and the maintenance level calculation DB 408. In addition, the facility maintenance apparatus 400 includes a maintenance information calculation unit 414 that obtains maintenance information of each facility using the facility DB 406 and the maintenance information DB 410.

  FIG. 4 is a diagram illustrating an example of the facility DB 406. As illustrated in FIG. 4, the facility DB 406 stores facility IDs (identification) assigned to the respective wind power generation facilities 200-1 to 200-n. In addition, in the equipment DB 406, the cost for providing the maintenance service, the amount paid by each wind power generation equipment for the provision of the maintenance service, the ratio between the cost and the payment amount, and the maintenance level correspond to each equipment ID. Stored. The maintenance level represents the degree of quality of the maintenance service provided to the wind power generation facilities 200-1 to 200-n.

  FIG. 5 is a diagram illustrating an example of the maintenance level calculation DB 408. As shown in FIG. 5, in the maintenance level calculation DB 408, the maintenance level is set stepwise in advance according to the ratio between the cost required for providing the maintenance service and the actual payment amount. Specifically, when the payment amount for providing the maintenance service is “0”, the ratio of the cost required for providing the maintenance service and the payment amount is “0”, and the maintenance level is “0”. When the ratio between the cost required for providing the maintenance service and the payment amount is “1% to 30%”, the maintenance level is “1”. When the ratio between the cost required for providing the maintenance service and the payment amount is “31% to 70%”, the maintenance level is “2”. When the ratio between the cost required for providing the maintenance service and the payment amount is “71% to 100%”, the maintenance level is “3”. In this embodiment, an example in which the maintenance level is set according to the ratio between the cost required for providing the maintenance service and the actual payment amount is shown, but the present invention is not limited to this. For example, the maintenance level calculation DB 408 can set the maintenance level according to the actual payment amount for the maintenance service, or can set the maintenance level according to the accumulated unpaid amount of each facility.

  FIG. 6 is a flowchart of processing of the maintenance level calculation unit 412. When the amount paid by each of the wind power generation facilities 200-1 to 200-n as the consideration for providing the maintenance service is input via the payment amount input unit 404, the maintenance level calculation unit 412 stores the payment amount in the facility DB 406. Store (step S101). The maintenance level calculation unit 412 calculates the ratio of the expense and payment amount required for providing the maintenance service of the wind power generation facilities 200-1 to 200-n preset in the facility DB 406, and stores it in the facility DB 406 (step S102). ). The maintenance level calculation unit 412 refers to the maintenance level calculation DB 408, reads the maintenance level corresponding to the ratio of the cost required for providing the maintenance service and the amount of payment calculated in step S102, and stores it in the facility DB 406 (step S103). .

  In the example of FIG. 4, since the wind power generation facility with the equipment ID “A” has not paid any compensation for the provision of the maintenance service, the ratio between the cost required for the provision of the maintenance service and the payment amount becomes “0”, and the maintenance An example in which the level is “0” is shown. In addition, since the wind power generation facility with the equipment ID “B” pays the same amount as the consideration for the provision of the maintenance service, the ratio of the cost required for the provision of the maintenance service and the payment amount becomes “100%”, and the maintenance level is An example of “3” is shown. In addition, the wind power generation facility having the facility ID “C” shows an example in which the maintenance level is “1” because the ratio between the cost required for providing the maintenance service and the payment amount is “20%”.

  FIG. 7 is a diagram illustrating an example of the maintenance information DB 410. In the maintenance information DB 410, maintenance information is stored in advance based on the past maintenance history of the wind power generation facilities 200-1 to 200-n. Also, the maintenance information DB 410 stores conditions (maintenance information provision conditions) related to the maintenance level of the equipment for providing the maintenance information to the equipment corresponding to each of the plurality of maintenance information.

  Specifically, in the case where the maintenance information is such that an emergency stop of the equipment is recommended because the equipment is expected to be damaged in the near future, provision conditions with maintenance levels of 0 to 3 are set. In addition, when the maintenance information is a content that recommends replacement of parts because a failure of the device within 3 months is expected, provision conditions with maintenance levels of 1 to 3 are set. In addition, if the maintenance information is that the failure of the equipment is predicted within half a year, it is recommended that parts maintenance be recommended, and further measures to improve power generation efficiency should be provided. Is set. In addition, if the maintenance information is a content that regularly provides a policy to maximize power generation efficiency, a planned equipment replacement plan, and a planned parts procurement plan, apart from information related to equipment failure, A provision condition with a maintenance level of 3 is set. In addition, as a measure for improving the power generation efficiency, for example, there is a suggestion of changing an operation parameter such as setting of the angle of the blade 201.

  FIG. 8 is a flowchart of the process of the maintenance information calculation unit 414. The maintenance information calculation unit 414 receives a device state signal from the wind power generation equipment 200-1 to 200-n via the signal transmission / reception unit 408 (step S201). On the other hand, the maintenance information calculation unit 414 refers to the facility DB 408 and reads the maintenance level of the facility that has transmitted the device status signal (step S202). Subsequently, the maintenance information calculation unit 414 refers to the maintenance information DB 410 and searches for maintenance information corresponding to the device status signal received in step S201 in consideration of the maintenance information history of the facility (step S203). Even if the occurrence of the device status signal occurs frequently, if the maintenance measure is insufficient, the maintenance information is provided by referring to the maintenance information history in the maintenance information DB 410, such as making an emergency stop recommendation. Here, in the maintenance information history of the maintenance information DB 410, for example, “If an output peak appears in a certain frequency band of the device status signal, the device has been replaced because the device has been damaged”. A history of maintenance information is stored. Also, in the maintenance information history, for example, “When an output peak appears in another frequency band of the device status signal, the device has been replaced after three months since the device has been damaged.” A history of maintenance information is stored. In addition, the maintenance information history stores a status of equipment damage and a history of countermeasures taken for the state of damage for each frequency band in which the output peak of the equipment status signal appears. The maintenance information calculation unit 414 searches for maintenance information corresponding to the device status signal by comparing the frequency band in which the peak of the received device status signal appears with a plurality of frequency bands stored in the maintenance information history. To do.

  If the maintenance information calculation unit 414 searches the maintenance information DB 410 in step S203 and there is maintenance information corresponding to the device status signal, the maintenance level read in step S203 satisfies the provision condition of the maintenance information. Whether or not (step S204). If the maintenance level read in step S203 satisfies the maintenance information provision condition (YES in step S204), the maintenance information calculation unit 414 reads the maintenance information from the maintenance information DB 410 and causes the signal transmitting / receiving unit 408 to operate. To the corresponding equipment (step S205). On the other hand, when the maintenance level read in step S203 does not satisfy the maintenance information provision condition (NO in step S204), the maintenance information calculation unit 414 ends the process without reading the maintenance information from the maintenance information DB 410. To do. In each of the wind power generation facilities 200-1 to 200-n, when the maintenance information is received from the facility maintenance device 400, the local maintenance staff, for example, according to the received maintenance information, for example, the emergency stop of the wing 201 or the power generation device 204, the parameter Carry out maintenance work such as adjustment and replacement of parts.

  As described above, according to the present embodiment, instead of providing maintenance information corresponding to the device status signal unconditionally to the wind power generation facility, the wind power generation facility is paid according to the amount paid by the wind power generation facility as a price for the maintenance service. Differences can be made in maintenance services. For example, since the wind power generation facility having the facility ID “A” has not paid for the maintenance service, the maintenance level is set to “0”. The wind power generation facility with the facility ID “A” is provided with only the maintenance information indicating that the emergency stop of the operation should be performed because there is a possibility that the device may be damaged in the near future. . In this way, by providing the minimum necessary maintenance service even if the facility is not fully paid, it is possible to suppress the possibility that the equipment of the facility will break down and lose the opportunity to pay the price.

  Further, the wind power generation facility having the facility ID “B” pays the price for the maintenance service, but the maintenance level is set to “1” because the payment amount is not sufficient. For the wind power generation facility with the facility ID “B”, in addition to the service at the maintenance level “0”, for example, maintenance information indicating that a part should be replaced because a failure within 3 months is expected. provide. On the other hand, the wind power generation facility having the facility ID “C” pays the entire amount for the maintenance service, so the maintenance level is set to “3”. And for wind power generation equipment with equipment ID “C”, in addition to maintenance services with maintenance levels “0” and “1”, measures for maximizing power generation efficiency and low maintenance costs over the medium to long term To provide equipment replacement and parts procurement plans.

  As a result, according to the present embodiment, it is considered that the recovery rate of the compensation from the facility for the provision of the maintenance information can be improved by giving the facility an incentive to pay the compensation for the provision of the maintenance information. . In particular, when subcontracting maintenance work such as power generation facilities and power facilities constructed overseas or relatively small and medium-sized wind power generation facilities, solar power generation facilities, and hydroelectric power generation facilities in Japan, the recovery rate of compensation for maintenance information This example is useful because it is desired to improve the above.

  In addition, the present embodiment includes a payment amount input unit 404, a maintenance level calculation DB 408, and a maintenance level calculation unit 412. Therefore, if the amount paid for the provision of the maintenance information by the equipment is input to the payment input unit 404, the maintenance level of the equipment is automatically set by the maintenance level calculation unit 412, so that the maintenance level of the equipment is set. Alternatively, the resetting operation can be simplified.

  Further, in this embodiment, the time series measurement signals measured by the optical fiber temperature / vibration sensor 210 and the strain sensor 212 are standardized by Fourier transform, and for example, if a signal in a frequency band characteristic of damage is detected, the device status signal Is transmitted to the equipment maintenance apparatus 400. Therefore, according to the present embodiment, compared with the case where the time-series measurement signals measured by the optical fiber temperature / vibration sensor 210 and the strain sensor 212 are constantly transmitted to the equipment maintenance device 400 as they are, the signal communication amount is reduced. Can be reduced. In addition, according to the present embodiment, the monitoring staff of the equipment maintenance device 400 only has to wait for the arrival of the equipment status signal and start the monitoring activity. It is possible to monitor intensively with few observers. As a result, the number of personnel arranged in the facility maintenance device 400 can be reduced. In addition, although the present Example showed the example which standardizes a measurement signal by Fourier-transforming, it is not restricted to this. For example, the measurement signal can be converted and standardized by wavelet conversion. Further, the measurement signal can be converted and standardized by Laplace conversion.

  In this embodiment, since the equipment maintenance apparatus 400 creates a database of past maintenance history of the equipment to be maintained in correspondence with the equipment status signal, the equipment maintenance apparatus 400 automatically receives the equipment status signal when it is received. Thus, maintenance information can be obtained in an effort, and the burden on maintenance personnel is reduced. In addition, when this example is applied to an overseas power generation facility or power facility with a large time difference, local daytime equipment maintenance work will be performed locally using the time difference, and local nighttime equipment maintenance work. Can be performed in the daytime by the equipment maintenance apparatus 400. As a result, according to the present embodiment, the working hours of the maintenance staff of the equipment maintenance apparatus 400 and the local maintenance staff of the equipment can be rationalized, so that the cost for maintenance work can be further reduced.

  In addition, although the present Example showed the example which provides the policy for maximizing power generation efficiency, and the policy for suppressing maintenance cost as a maintenance service when a maintenance level is high, it is not restricted to this. For example, the facility maintenance apparatus 400 can give an incentive to pay maintenance service costs by increasing the frequency of providing maintenance information to a facility with a high maintenance level and finely increasing the maintenance service. In addition, the facility maintenance device 400 provides an incentive for payment of maintenance service costs by, for example, providing facilities for a low maintenance level after the fact without providing a measure for improving power generation efficiency in real time. be able to.

  Although the present embodiment has been described mainly with respect to the facility maintenance system, the facility maintenance device, and the facility maintenance method, the present invention can be implemented by executing the facility maintenance program prepared in advance by a computer. Functions similar to the example can be realized. That is, the facility maintenance program performs a status signal reception procedure for receiving, via a communication network, a device status signal obtained based on a measurement signal of a sensor that measures the status of a maintenance target device from a facility having the maintenance target device. Let the computer run. In addition, the equipment maintenance program sets maintenance information related to the equipment to be maintained and conditions relating to the maintenance level of the equipment for providing the maintenance information to the equipment corresponding to each of a plurality of types of equipment status signals. The maintenance level set in advance for the equipment according to the amount paid by the equipment as a consideration for the provision of maintenance information corresponding to the equipment status signal received in the status signal receiving step based on the maintenance information database The computer is caused to execute a maintenance information calculation procedure for reading maintenance information that satisfies a condition relating to the maintenance level. The facility maintenance program causes the computer to execute a maintenance information transmission procedure for transmitting the maintenance information read in the maintenance information calculation procedure to the facility via the communication network.

  In addition, in the equipment maintenance program, the maintenance level is set in stages according to the payment amount input procedure for entering the amount paid by the equipment as the consideration for providing the maintenance level and the amount that the equipment pays for the provision of maintenance information. On the basis of the maintenance level calculation database, the computer can further execute a maintenance level calculation procedure for reading a maintenance level corresponding to the payment amount input in the payment amount input procedure and setting a maintenance level of the equipment. The facility maintenance program can be distributed to computers via a communication network such as the Internet. The facility maintenance program can also be executed by being recorded on a memory, a hard disk, or other computer-readable recording medium provided in the computer and being read from the recording medium by the computer.
