Intelligent photoelectric direct-reading remote water meter based on broadcast television white frequency spectrum

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of intelligent water meters, in particular to an intelligent photoelectric direct-reading remote transmission water meter based on radio and television white spectrum. Background technique [0002] A smart water meter is a modern micro electronic technology ,modern Sensing Technology and smart IC Compared with the traditional water meter, which generally only has the functions of flow collection and mechanical pointer display of water consumption, it is a great progress. [0003] With the advancement of science and technology, the research and development of smart water meters is becoming more and more mature. In addition to recording and electronically displaying water consumption, smart water meters can also control water consumption according to the agreement, and automatically complete the water fee calculation of the ladder water price. At the same time water use data storage functions, such as a...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an intelligent photoelectric direct-reading remote water meter based on the radio and television white spectrum, which has the advantages of strong signal transmission effect and solves the problem of poor signal transmission generally existing in existing intelligent water meters. Disadvantages, the transmission distance between the NB-IOT chip and the base station is about 500 meters, and the transmission distance between the LORA chip and the base station is about 800 meters. way, which greatly restricts the application of NB-IOT and LORA networks in places where it is inconvenient for operators to access the network and to obtain electricity on site, and it is not easy to use
