[0002] Traditional fire hydrants are separate entities, and their status cannot be known by the owner or supervisor when the fire hydrant is taking water. In order to transform the traditional fire hydrant, the Chinese invention patent with the publication number CN109260637A discloses an intelligent fire hydrant, including an upper plug body, a lower plug body and a water inlet pipe. The upper plug body and the lower plug body are arranged up and down and are detachably connected. The lower end of the lower plug body is detachably connected to the water inlet pipe. The upper plug body is fixed with a water intake port and rotatably provided with a plug cap. A valve is horizontally arranged in the lower plug body. A connecting rod connects the plug cap and the valve. The plug cap can be rotated under the transmission action of the connecting rod to open or close the valve. The lower plug body is provided with an intelligent fire hydrant micro-power collector for collecting the fire hydrant status and identifying the EPC tag and mobile terminal. The EPC tag is held by the water-taking personnel and carries the identity information of the water-taking personnel. The mobile terminal is held by the inspection personnel and carries the identity information of the inspection personnel. Beneficial effects: It can reduce costs and help promote application.
