  The present invention relates to a power supply design method of a monitoring device and a monitoring system. More specifically, the present invention is directed to, for example, a technique for designing and setting specifications for power sources of monitoring devices installed in distribution poles and transmission towers, and monitoring of specifications designed and set by such techniques. The invention relates to a monitoring system comprising a power supply of the device.

  Electric power companies are required to reduce costs and reduce labor burdens by improving the patrol efficiency of outdoor equipment. The inspection work includes checking the separation distance between the electric wire and heavy machinery at the construction site around the power transmission and distribution line, checking the separation distance between the trees and vine plants and the electric wire, and checking the nesting of crows etc. . Among such patrol operations, there are many operations that can be supported or substituted by long-term fixed point monitoring using still images. Therefore, if an inexpensive monitoring device is disposed in a wide area and an abnormality can be automatically detected by video analysis and notification can be made to the person in charge only when there is an abnormality, there is a possibility that the inspection efficiency can be improved.

  A conventional equipment monitoring system is, for example, a equipment monitoring system in which a monitoring device monitors one or a plurality of displays for displaying the state of equipment and notifies the monitoring center of a remote location of the state of the equipment; An abnormality detection unit that detects an abnormality in the facility and outputs a detection signal, a contact that is opened and closed by the detection signal from the abnormality detection unit, a power supply connected to the contact, and a power supply when the contact is closed due to an abnormality detection And monitoring means for detecting the presence or absence of light emission using the imaging means for imaging the display and the image signal output from the imaging means, and notifying the condition of the facility There is an apparatus provided with an image processing apparatus that generates data and transmits the notification data to a remote monitoring center (Japanese Patent Application Laid-Open No. 2008-101118).

  The resolution of the still image acquired by the imaging by the imaging means 12 is not limited to a specific number of pixels, and the monitoring purpose of the monitoring object (in other words, the monitoring content) is also taken into consideration. The number of pixels is selected as appropriate such that the situation relating to the object can be determined, or the image data can be used to calculate the size and distance of the object to be monitored by image analysis / image processing or the like.

Communication by the used mesh network may be used.

  The image data may be read from the recording unit 13 b and transmitted by e-mail to the terminal device of the person in charge of monitoring, via the communication unit 13 c and the network. The person in charge of monitoring who has received the still image confirms the soundness of the monitored object, such as the confirmation of the separation distance between the monitored object and the vine.

  The image data output from the imaging unit 12 and input to the control unit 13 is transferred as it is to the terminal device of the person in charge of monitoring by the communication unit 13 c without being stored in the recording unit 13 b. It is good. In that case, the control means 13 may be configured not to have the recording unit 13 b.

  As a power source of the monitoring device 11 for enabling long-term observation (for example, observation of one year or more than one year) in a state where the monitoring device 11 is independent without using an external power supply, A combination with the storage battery 15 is used.

  The electricity that the storage battery 15 outputs (in other words, discharges) is input to the power supply controller 16 and is used to supply power to the control means 13 via the power supply controller 16.

  Also, depending on the configuration of the monitoring device 11, power may be supplied directly from the power supply controller 16 to the imaging unit 12 as needed (specifically, for example, when the imaging unit 12 does not receive power supply from the control unit 13). Ru.
