The invention relates to a remote state
monitoring system of a fire hydrant. The remote state
monitoring system comprises
a site detection device arranged on the fire hydrant, and a monitoring center positioned at a remote end, wherein the site detection device comprises a
water pressure sensor, a flow sensor, a tilt angle sensor, a prying-resistant sensor, a geographic information positioning module, an
identity recognition module, a
buzzer, a microcontrol
chip circuit and a
wireless transmission module, wherein the
water pressure sensor is positioned at the front end of a
water stop pad and is connected with the microcontrol
chip circuit, the prying-resistant sensor comprises a
reed switch and a permanent
magnet arranged on a fire hydrant valve rod for being matched with the
reed switch to work, the
reed switch outputs a
signal after acting and the
signal is output to the microcontrol
chip circuit, and the microcontrol chip circuit transmits the acquired data to the monitoring center through a star topology structure of the
wireless transmission module of the fire hydrant in a region and in a self-networking or relaying manner and then through a
wireless network. The remote state
monitoring system is capable of remotely monitoring the state of the fire hydrant, preventing the fire hydrant from being illegally used, displaced and damaged, and providing
relevant information of the fire hydrant to maintenance or fire emergency of the personnel patrol.
