The invention discloses a fire hydrant water anti-theft warning device based on the passive wireless Internet of Things. The fire hydrant water anti-theft warning device comprises a generator. One end of the generator is installed in a pipeline shell, and an impeller is connected to a rotating shaft of the generator. The generator is connected with a power source management circuit board, a microcontroller and a GPRS module. A radio frequency antenna is further connected to the end of the GPRS module. The generator, the power source management circuit board, the microcontroller, the GPRS module and the radio frequency antenna are designed into an assembly in mutual connection and are installed in the same protection cover. According to the fire hydrant water anti-theft warning device, electromotive force formed after a fire hydrant is opened is connected and transmitted to the Internet through the GPRS module, water supply companies and the public security and fire departments can monitor the warning information of fire hydrants and the stolen flow of fire hydrant water in the whole region through dynamic web page monitoring interfaces based on the Internet, persons stealing the fire hydrant water are investigated and treated in time according to the information and are penalized and educated, and the fire hydrants are managed and maintained in time.
