The measurement unit 140 measures data related to the weather around the steel tower on which the transmission line to be monitored is installed. The measurement unit 140 includes, for example, a temperature/humidity meter 141, a barometer 142, an illuminance meter 143, and an analog anemometer 144. The measurement unit 140 acquires data related to the weather around the power transmission line and transmits the data related to the weather to the control device 160 at the timing synchronized with the shooting by the shooting unit 130. The temperature/humidity meter 141, the barometer 142, and the illuminance meter 143 each output a digital signal to the control device 160.

The digital signal converted by the A/D converter 145 is output to the control device 160.

The power supply unit 150 supplies (powers) electricity necessary for the operations of the imaging unit 130, the measurement unit 140, and the control device 160. The power supply unit 150 includes a solar panel 151, a charge/discharge controller 152, a storage battery 153, and a power supply management module 154. The solar panel 151 is electrically connected to the charge/discharge controller 152, the charge/discharge controller 152 is electrically connected to the storage battery 153, and the storage battery 153 is electrically connected to the power management module 154.

The solar panel 151 preferably has an output of 25 W or more, for example.

On the back surface of the solar panel 151, a mounting bracket 120 for mounting and fixing to a steel tower member is fixed. Therefore, by adjusting the inclination of the mounting bracket 120, the solar panel 151 can be inclined at an angle that can efficiently absorb the energy of sunlight. Only one solar panel 151 may be installed on the steel tower, or a plurality of solar panels 151 may be installed.

The charge/discharge controller 152 adjusts the electricity generated by the solar panel 151 to a voltage suitable for charging the storage battery 153 and supplies the electricity to the storage battery 153. Further, the charge/discharge controller 152 controls the amount of discharge to the storage battery 153 according to the amount of charge of the storage battery 153 in order to prevent overcharge of the storage battery 153.

The storage battery 153 is, for example, a sealed lead storage battery. Considering the case where the solar panel 151 cannot generate electricity for a long time due to lack of sunlight, it is preferable to have a capacity of 9 Ah or more, for example.

The power management module 154 is electrically connected to the imaging unit 130 and the control device 160, and supplies the electricity charged in the storage battery 153 to the imaging unit 130 and the control device 160.

The communication unit 161 is, for example, a 3G dongle that is connected to a single board computer and can communicate with an external computer or the like. By using the 3G dongle, communication with the outside can be realized at a low cost.

The monitoring apparatus 100 transmits the fixed point image of the power transmission line and the weather data around the fixed point image to the WEB server 200, for example, every 30 minutes. Since the amount of data transmitted to the WEB server 200 is kept low, it is possible to monitor the power transmission line without any problem even with a relatively low-speed communication means.

The storage unit 162 includes a RAM (Random Access Memory), a ROM (Read Only Memory), a flash memory, and the like. The storage unit 162 stores programs executed by the control unit 163 and various data.

Next, a method of mounting the monitoring device 100 according to the embodiment of the present invention will be described. Hereinafter, it is assumed that the mounting brackets 120 are fixed to the housing 110 and the solar panel 151, respectively.

First, the mounting bracket 120 fixed to the housing 110 is fixed to a steel tower on which a transmission line to be monitored is installed.

Next, the mounting bracket 120 fixed to the solar panel 151 is fixed to the steel tower on which the transmission line to be monitored is installed. The mounting bracket 120 fixed to the solar panel 151 is fixed to the steel tower at a position different from the mounting bracket 120 fixed to the housing 110.

Next, in order to adjust the orientation of the camera module built in the housing 110, the mounting bracket 120 fixed to the housing 110 is adjusted to an arbitrary angle. Since the mounting bracket 120 is configured to be rotatable in three axial directions that are perpendicular to each other, the housing 110 can be tilted in any direction.

Further, the mounting bracket 120 fixed to the solar panel 151 is adjusted to an arbitrary angle so that the solar panel 151 faces the direction with the highest power generation efficiency. Since the mounting bracket 120 is configured to be rotatable in three axial directions perpendicular to each other, the solar panel 151 can be tilted in any direction. The solar panel 151 is positioned in a direction with the highest power generation efficiency in consideration of, for example, a position attached to a steel tower, surrounding obstacles, and a trajectory of the sun. The above is the method of mounting the monitoring device 100.

Next, with reference to FIGS. 7 and 8, a flow of a series of processes executed by the power transmission equipment monitoring system 1 according to the embodiment of the present invention will be described.

(Observation data transmission process)
The flow of the observation data transmission process executed by the control device 160 of the monitoring device 100 will be described with reference to the flowchart of FIG. 7. The observation data transmission process is a process of acquiring observation data at a predetermined cycle and transmitting the observation data to the WEB server 200. The observation data transmission process is started when the monitoring device 100 is activated.

First, the control unit 163 acquires observation data including data regarding a fixed point image captured by the capturing unit 130 and data regarding weather measured by the measuring unit 140 (step S11). The internal timer of the power management module 154 starts the process of measuring time when the process of step S11 is started.

Next, the control unit 163 stores the observation data acquired in step S11 in the storage unit 162 in association with the identification information assigned to the monitoring device 100 and the data acquisition time (step S12).

Next, the control unit 163 creates a weather graph and an output file based on each weather data acquired in step S11 (step S13). The weather graph created in step S13 is created for each monitoring device 100 and shows the time transition of the weather data regarding temperature, humidity, atmospheric pressure, solar radiation, wind speed, and the like. The weather graph may be recorded in, for example, a PNG (Portable Network Graphics) file. The output file created in step S13 is created for each monitoring device 100, and includes numerical values of meteorological data relating to temperature, humidity, atmospheric pressure, solar radiation, wind speed, and the like associated with the data acquisition time. The output file is, for example, a CSV (Comma Separated Values) file.

Next, the control unit 163 controls the communication unit 161 to transmit the image data acquired in step S11, the data regarding the weather graph created in step S13, and the output file to the WEB server 200 (step S14). ). During the process of step S14, the control unit 163 causes the WEB server 200 to transmit the identification information such as the device ID (Identification) and the password. The WEB server 200 authenticates the monitoring device 100 and receives the observation data from the monitoring device 100 when the identification information and the password received from the monitoring device 100 match the identification information and the password stored in the WEB server 200. ..

Next, the control unit 163 continues only the process of counting by the internal timer of the power management module 154 and stops the power supply from the power supply unit 150 to each device of the monitoring device 100, and performs the process of step S11. It is determined whether or not a predetermined period (for example, 30 minutes) has elapsed from (step S15).

When the predetermined period has elapsed from the process of step S11 (step S15; Yes), the power supply from the power supply unit 150 to each device of the monitoring device 100 is restarted, and then the process returns to step S11. The consumption of the storage battery 153 can be suppressed by stopping the power supply from the power supply unit 150 at a time when the photographing of the fixed point image by the photographing unit 130 and the measurement of the meteorological data by the measuring unit 140 are unnecessary.

On the other hand, when the predetermined period has not elapsed from the process of step S11 (step S15; No), only the process of counting by the internal timer of the power management module 154 is continued, and each device of the monitoring device 100 from the power supply unit 150 is continued. The process waits until a predetermined period elapses while the power supply to the device is stopped. The above is the flow of the observation data transmission processing.

(Public directory move process)
Next, the flow of the public directory moving process executed by the control unit 230 of the WEB server 200 according to the embodiment will be described with reference to the flowchart of FIG. The public directory moving process is a process of moving various data acquired from each monitoring device 100 to the public directory at a predetermined timing. The public directory moving process is started when the WEB server 200 is activated.

First, the control unit 230 uses the communication unit 210 to acquire image data, data relating to a weather graph, and an output file from each monitoring device 100 (step S21).

Next, the control unit 230 stores the image data, the data regarding the weather graph, and the output file from each monitoring device 100 acquired in step S21 in the storage unit 220 (step S22).

Next, the control unit 230 determines whether or not a predetermined time (for example, 5 minutes) has elapsed from the process of step S21 or the process of step S24 (step S23). When the predetermined time has elapsed (step S23; Yes), the control unit 230 moves the image data, the data related to the weather graph and the file acquired in step S21 to the public directory of the storage unit 220 (step S24). , And returns to the process of step S21.

In the process of step 24, the control unit 230 determines whether or not the number of data of the image data stored in the public directory of the storage unit 220, the data regarding the weather graph and the number of files has reached the upper limit, and the number of data has reached the upper limit.
