FIG. 10 is a flowchart showing the flow of the monitoring process executed by power receiving facility management apparatus 100 in the present embodiment. Referring to FIG. 10, power receiving facility management device 100 first determines whether a predetermined period has elapsed (step S1). The predetermined period indicates an interval at which the power receiving facility management device 100 monitors the power receiving facility 200.
The predetermined period is a value arbitrarily determined according to the power receiving facility 200. For example, when the usage period of the power receiving facility 200 exceeds a predetermined usage period, the predetermined period may be shortened for frequent monitoring.

If the predetermined time has elapsed, step S2
If not, it goes into a standby state. Instead of the standby state, an interrupt may be generated at the time when a predetermined period has elapsed, and the processing after step S2 may be executed.

In step S 2, a photographed image obtained by photographing with the camera 205 is received from the personal computer 201 via the network 300. In this case, the personal computer 2
A request for transmitting an image is issued to the personal computer 201, and a captured image is received from the personal computer 201.

In the next step S3, the reference image stored in the reference image D / B 140 of the storage unit 102 is read. This reference image is an image corresponding to the captured image received in step S2. For example, when there are a plurality of images photographed by the camera 205, or when there are a plurality of cameras 205 and a plurality of parts of the power receiving equipment 200 are photographed, a reference image corresponding to each image is stored in advance. It is stored in the reference image D / B 140 of the unit 102.

When a plurality of parts of the power receiving equipment 200 are to be monitored, a monitoring process is performed for each of all captured images.

In the next step S4, an image comparison process is performed. The image comparison process is a process of comparing the captured image received in step S2 with the reference image read in step S3. Although details will be described later, it is determined by the image comparison process whether or not there is an abnormality.

In step S5, it is determined whether or not an abnormality has been determined in the image comparison processing in step S4. If it is determined that there is an abnormality, step S6 is performed, and the process ends. If it is determined that there is no abnormality, the process ends without performing step S6.

In step S 6, a warning message such as “XX is deformed” or “XX is discolored” is displayed on the display of the terminal 108. "○○
“○” indicates a part name. The content of the warning message is determined based on the result of the image comparison processing in step S4.

Alternatively, the above message may be uttered from the speaker of terminal 108. Further, a warning sound may be emitted from a speaker provided in the terminal 108.

As a result, the terminal 108 of the power receiving facility management apparatus 100 displays that there is a possibility that a predetermined component of the power receiving facility 200 may fail.
The user of the terminal 108 at 00 can obtain information that a failure may occur in the power receiving facility 200. Further, in order to inspect the power receiving facility 200, a repair person can be dispatched to inspect the power receiving facility 200. Thereby, failure of the power receiving facility 200 can be prevented beforehand, and stable operation of the power receiving facility 200 can be maintained.

FIG. 11 is a flowchart showing the flow of the image comparison process executed in step S4 of FIG.
Referring to FIG. 11, in the image comparison process, an area of the inspection target component is extracted from the captured image received in step S2 of FIG. 10 (step S11). The approximate position of the inspection target component is obtained from the reference image read in step S3. In the reference image, the positions of the components included in the reference image are stored in the storage unit 102 in advance corresponding to the reference image, and the position data is read out simultaneously with the reference image. Position information of the inspection target component read together with the reference image;
An area of the part to be inspected is extracted from the contour information obtained from the captured image.

In the next step S12, an area of the part to be inspected is extracted from the reference image. An area of the inspection target component is extracted from the reference image based on the position of the inspection target component read together with the reference image.

By performing pattern matching between the region extracted in step S11 and the region extracted in step S12, the shapes of the two regions are compared (step S13). As a result of the comparison, if the two regions have the same shape, the process proceeds to step S15; otherwise, the process proceeds to step S20 (step S14).

In step S20, the process returns due to the abnormal shape, and the image comparison processing ends. In this case, it is determined that there is an abnormality in step S5 in FIG. 10, and the process proceeds to step S6. Further, in step S6, since the shape is determined to be abnormal in the image comparison processing, a warning message "XXX is deformed" is displayed.

In step S15, the pixel value of the reference point is compared. The reference point is a pixel determined based on the reference data shown in FIG. Reference data corresponding to the reference image read in step S12 is read from reference image D / B 140 in storage unit 102, and based on the read reference data, the luminance value of the read reference data and the reference data The luminance value of the pixel of the captured image specified by the coordinates is compared. As a result of the comparison, it is determined whether or not the difference between the brightness values is within 5% (step S16).

If the difference between the brightness values is within 5%, the process proceeds to step S17, otherwise, the process proceeds to step S2.
Proceed to 1. This luminance value was a value within the range of 0 to 255. Therefore, since 5% of 256 is 12.8, it is determined whether or not the difference between the luminance values is larger than 12.8. If the difference is larger, the process proceeds to step S21.

In step S21, the process returns with a color abnormality. Thereby, it is determined that there is an abnormality in step S5 in FIG. 10, and the process proceeds to step S6. In step S6, a warning message "XX is discolored" is displayed.

Note that, here, it is determined whether or not the difference between the luminance values is within 5%. However, the present invention is not limited to this as long as a change in brightness can be detected in the region of the component in the image. For example, in the case where a failure occurs due to the occurrence of rust on a part, the difference between the luminance values of the images obtained by photographing in the case where there is no rust and in the case where the rust has occurred and the failure is determined in advance. After the measurement, the threshold value can be determined based on the difference between the luminance values.

Further, in a case where dust is attached to a component and causes a failure, the image obtained by photographing the component obtained when the component is free of dust and the one obtained when the component is damaged due to dust may be used. The brightness value may be measured in advance, and the threshold value may be determined based on the difference between the brightness values.

In the next step S17, it is determined whether or not there is a next reference point. If there is a next reference point, the process proceeds to step S15, and the above processing is repeated. If there is no next reference point, the process proceeds to step S18.

In the next step S18, it is determined whether or not there is a next part to be inspected. This is determined based on data on the inspection target component read together with the reference image. If there is an inspection target component for which the processing of steps S11 to S17 has not been performed, the process proceeds to step S11.
Proceed to 19.

In step S19, the process returns to normal. Thereby, in step S5 of FIG. 10, it is determined that there is no abnormality, and the process ends without executing step S6.

Next, a power receiving facility management process performed by the power receiving facility management apparatus 100 will be described. FIG. 12 is a flowchart illustrating the flow of the power receiving facility management process performed by power receiving facility management apparatus 100 according to the present embodiment.
Referring to FIG. 12, power receiving facility management device 100 determines whether a predetermined period has elapsed (step S3).
1). The predetermined period is a period determined by a power contract concluded between each customer and the power company to calculate a power rate, and is determined by the item 115 of the settlement date of the power contract database 110.

Therefore, the determination as to whether or not the predetermined period has elapsed is made for each customer. The elapse of the predetermined period is determined from the closing date item 115 of the power contract database 110 stored in the storage unit 102. If it is determined that the predetermined period has elapsed, the process proceeds to step S2, and if not, the process waits until the predetermined period has elapsed. Since the settlement date differs for each customer, it is determined for each customer whether a predetermined period has elapsed. Therefore, if it is determined that the predetermined period has elapsed for any of the customers, the process proceeds to step S32, and if not, it enters a standby state.

In step S 32, the communication unit 105 issues an instruction from the power receiving facility management apparatus 100 to the personal computer 201 of the customer to request transmission of the power consumption.
And transmitted via the network 300. In this case, the customer data is read from the customer D / B 130 based on the customer ID for which the predetermined period has passed in step S31, and the customer ID to which the transmission request of the power consumption is transmitted is determined. The address stored in association with the address is read. Thereby, the personal computer 2
01 network address is specified.

When the personal computer 201 receives the power consumption transmission request from the power receiving facility management device 100, the power consumption received from the meter reading device 204 and stored in the hard disk or the like is read. In the personal computer 201, a customer ID assigned to the customer is stored in a storage device such as a hard disk in advance, and the customer ID is read from the storage device. The read customer ID and power consumption are stored in the network 300
Is transmitted to the power receiving facility management apparatus 100 via the. In addition,
Instead of storing the customer ID in the storage device of the personal computer 201, the customer ID is transmitted together with the power consumption transmission request from the power receiving facility management device 100,
The customer ID and the power consumption received by the personal computer 201 may be returned to the power receiving facility management device 100.

Furthermore, the customer ID and the power consumption are transmitted from the consumer's personal computer 201 to the power receiving facility management apparatus 100 at predetermined time intervals without requesting the power receiving facility management apparatus 100 to transmit the power consumption. It may be. In this case, the power receiving facility management apparatus 100 uses the personal computer 201 of each customer.
May be stored for each customer ID in the storage unit 102, and the data of the customer ID may be read out after a predetermined period has elapsed, and the power consumption may be calculated. In this case, steps S32 and S33 become unnecessary.

When the customer ID and the power consumption are received from personal computer 201 in step S33, the same customer data as the received customer ID is stored in customer D / B 130.
(Step S34). The read customer data is temporarily stored in the RAM of the control unit 101.
