Problems solved by technology

The smart water meter mainly relies on the IC card to store the purchased water consumption, and uses the IC card to communicate with the processor of the user terminal to realize the user's water consumption. Since the data security of the IC card is not very high, the water consumption data is very low. It is easy to be tampered with, thereby stealing water; and, once the user loses the IC card, others can directly use the IC card, which also brings economic losses to the user

Abstract

The invention discloses an intelligent water meter system capable of preventing water stealing, which comprises a server side, a first IC card read-write module and a user terminal, wherein the server side comprises an IC card, the server comprises a password generating module, the password generating module is used for generating and storing a password, and the server is used for writing cryptographic water usage data into the IC card; the user terminal comprises a processor; the processor is used for reading the cryptographic water usage data in the IC card and communicating with the server to obtain the password, the processor comprises a decode module, and the decode module is used for decoding the water usage data according to the password; the processor is used for comparing the used water volume data and the usable water volume data, when the used water volume data is equal to the usable water volume data, control signal can be sent to the electronic control valve, so as to enable the meter body to be closed. The system guarantees the safety of the data in the IC card, and prevents the data in the IC card form being distorted.

Description

technical field [0001] The invention relates to an intelligent water meter system, in particular to an intelligent water meter system for preventing water theft. Background technique [0002] A smart water meter is a new type of water meter that uses modern microelectronic technology, modern sensing technology, and smart IC card technology to measure water consumption, transfer water data, and settle transactions. 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 improvement. In addition to recording and electronically displaying water consumption, smart water meters can also control water consumption as agreed. The smart water meter mainly relies on the IC card to store the purchased water consumption, and uses the IC card to communicate with the processor of the user terminal to realize the user's water consumption. Since the data security of the IC card i...
