Wireless based loosening monitoring system and method for conductor of distribution line

The invention relates to a wireless based loosening monitoring system and method for a conductor of a distribution line. The system comprises a plurality of conductor loosening early warning devices, a plurality of reinforced data concentrators and a background early warning server. When in use, the conductor loosening early warning devices are mounted to send a networking request to search the closest reinforced data concentrator, and a route list is recorded synchronously; a chain network is formed along the distribution line according to the route list by the short-distance wireless mode; the conductor loosening early warning devices are used for acquiring the displacement information of monitoring points in real time, analyzing whether the conductors at the monitoring points are loosened or fallen from clamps, uploading the conductor loosening early warning signals in real time by the short-distance wireless manner, and timely uploading the device state information to the reinforced data concentrators; the reinforced data concentrator is used for sending the acquired conductor displacement data and the early warning signal to the background early warning server through a GPRS/ exclusive power network. The system is small in size; a clamp type inductive coil is used for supplying electricity, so that the clamp type inductive coil is an electricity supply device and is also called a fixing clamp; the electrical isolating characteristic is good; the mounting is flexible and convenient, and the construction load is small.
