The invention relates to the technical field of intelligent water meters, and discloses an intelligent photoelectric direct-reading remote water meter based on a radio and television white
frequency spectrum, which comprises a mounting base, and a water outlet
pipe is fixedly mounted on the left side of the mounting base. According to the intelligent photoelectric direct-reading remote water meterbased on the broadcast television white
frequency spectrum, a broadcast television white spectrum
chip and a broadcast television white spectrum
base station are adopted to send and receive acquiredsensor data through a radio and television special idle
frequency band below 700Mhz; implementation of bidirectional
control function, the open area of the radio and television white
frequency spectrum base station is covered by about 20 kilometers; the urban coverage range is about 10 kilometers; a
radio frequency band below 700Mhz is used; the broadcast television white spectrum
chip adopts
frequency band communication lower than NB-IOT and LORA, so that the
power consumption is lower, the interference is smaller, the penetrating power is stronger, the normal broadcast television
signal transmission of the broadcast television is not influenced, and the advantages of wide coverage, low
energy consumption,
high frequency band
utilization rate and small interference are truly achieved.
