Abstract

The invention discloses a self-service recharging water meter based on lora wireless communication and code encryption, and relates to the technical field of water meters. The self-service rechargingwater meter based on lora wireless communication and code encryption comprises a wireless valve control water meter used for controlling opening, closing and prompting of water supply and installed ona water supply pipeline of a user, and a wireless code recharging device used for synchronizing information of the wireless valve control water meter and achieving recharging. In the present invention, a wireless technology is adopted, data interaction does not need close contact with the meter, the traditional water meter recharging mode in which the recharging action of a water meter can be completed only after an IC card is inserted into the meter or is in contact with the water meter is changed, the self-service recharging water meter is suitable for various installation environments andadopts code type recharging, users can finish remote recharging at home, the water meter is convenient to use, a dynamic secret key and a high-strength data encryption recognition technology are adopted, illegal data invasion is effectively prevented, every user has one meter and one card, cross use among neighbors is prevented, and the water meter is high in safety.

Description

technical field [0001] The invention relates to the technical field of water meters, in particular to a self-service recharging water meter based on lora wireless communication and code encryption. Background technique [0002] Conventional prepaid water meters are recharged with contact IC cards or radio frequency IC cards at present. The user takes the IC card to the water management department to pay the fee and downloads the payment record to the IC, and then needs to insert the IC card into the meter or touch the IC card to the water meter to complete the recharging of the water meter. [0003] However, the commonly used installation methods and environments of water meters, such as: underground installation in rural areas, installation of water meter wells in apartment buildings, outdoor installation, installation of water meter boxes, etc. Due to the closed area of ​​the water meter, underwater or outdoors, it is necessary to open the well cover, meter box door, and ...
