A power distribution network monitoring system includes a plurality of measuring instruments that are installed at predetermined positions on power lines constituting a power distribution network and configured to perform electrical measurement of the power lines; a data collection relay configured to receive data related to measurement results from the plurality of measuring instruments; an imaging unit that is disposed near the data collection relay and configured to capture an image including the data collection relay; an abnormality detector configured to use the image captured by the imaging unit to detect an abnormality in the data collection relay; and a storage unit configured to store image data taken by the imaging unit. The image data consists of a single image previously captured by the imaging unit. The abnormality detector compares the latest image captured by the imaging unit and the image data stored by the storage unit and determines whether or not an appearance of the data collection relay changes. If it is determined that there is no change in the appearance of the data collection relay, the image data in the storage unit is updated with the latest image captured by the imaging unit.

Power distribution network monitoring system and power distribution network monitoring device

A power distribution network monitoring system includes a CT sensor and a power management device. The CT sensor includes a measurement component and a transmitter. The measurement component is installed at a plurality of predetermined positions along a power line constituting the power distribution network, and measures current of the power line at each predetermined position. The transmitter wirelessly transmits, as transmission data, the power spectrums of the fundamental wave, third harmonic, and fifth harmonic, as well as the effective current values used to detect abnormalities in the power distribution network, the data being at least part of the data measured by the measurement components. The power management device includes a receiver and a management database. The receiver receives the transmission data. The management database stores the received data.

Power distribution network monitoring system for detecting abnormalities

A power distribution network monitoring system detects abnormalities that occur in a power distribution network using measuring instruments installed in the power distribution network. The power distribution network monitoring system includes a plurality of measuring instruments that are installed at predetermined positions on power lines on an upstream side of the downmost-stream power demander, among the power lines constituting the power distribution network and configured to perform electrical measurement of the power lines; and an abnormality detector configured to determine whether or not data related to the measurement result measured by the measuring instrument has been received a predetermined number of times within a predetermined length of time, and detect the abnormality.

A harmonic detection system () comprises a measurement component (), a harmonic abnormality determination unit (), and a smartphone (). The measurement component () is installed at a specific position on a distribution line constituting a distribution network (), and measures data related to the current of the distribution line. The harmonic abnormality determination unit () uses some or all of the data related to current as detection data to detect abnormality related to harmonics. The smartphone () is owned by a user (G), and notifies the user that an abnormality has occurred in the distribution line when a harmonic is detected.

Harmonic detection system

The present invention provides a handlebar locking mechanism and a handlebar locking device, each of which (i) can be used for a moving body whose traveling direction is changed with a handlebar and (ii) which makes it difficult to unlock the handlebar by a forcible method such as breaking. The handlebar locking device () includes an engagement hole () made in a steering column (), a lock pin () which locks a handlebar () in a case where a pin tip part () of the lock pin () is engaged with the engagement hole (), and a lock pin drive mechanism which (i) moves, in a case where the handlebar () is to be locked, the lock pin () so that the pin tip part () is engaged with the engagement hole () and (ii) moves, in a case where the handlebar () is to be unlocked, the lock pin () so that the pin tip part () is removed from the engagement hole (). The engagement hole (), the lock pin (), and the lock pin drive mechanism being contained and provided in a frame () of a bicycle () so as to be not viewable from outside of the bicycle ().

Handlebar locking mechanism, handlebar locking device, and moving body

The present invention provides a handlebar lock system which (i) can be used for a moving body whose traveling direction is changed with a handlebar and (ii) includes a handlebar locking device which makes it difficult to unlock the handlebar by a forcible method such as breaking. The handlebar lock system includes: a handlebar locking device (); and a user interface () which notifies a user of an operation state of the handlebar locking device (), which operation state includes at least a lock state of the handlebar (). The handlebar locking device () is provided in a frame of a bicycle so as to be not viewable from outside of the bicycle. The control section () identifies the operation state, and then outputs, via a communication section (), information indicative of the operation state thus identified. A control section () of the user interface () receives, from the handlebar locking device (), the information indicative of the operation state. According to the information thus received, the control section () notifies the user of operation information on the handlebar locking device ().
