Abstract

An IC card electronic water meter for tap water, comprising: a water meter and a control device, a flow sensor connected to the water meter, a position sensor, a flow sensor and an IC card socket connected to the signal input terminal of the core micro-control unit of the water meter control device, and the signal input terminal is also connected to the There is a battery voltage monitoring module and a voltage sensor; the signal output end of the micro-control unit is connected to the "water cut-off in arrears" valve through the valve opening / closing drive module, and the signal output end is also connected to a liquid crystal display module; a position sensor is set to ensure the water meter Placed horizontally to avoid errors and ensure the accuracy of the water meter; to solve the problem of malicious power outages, the battery is easy to replace, and to avoid the hidden danger of strangers entering the house due to battery replacement. The pulse power supply with variable cycle reduces the power consumption of the Hall element and saves electricity. The use of water pressure sensors and micro-holes for leakage can prevent "running water" caused by pipeline rupture and unintentional opening of the faucet after the water is cut off. The IC card uses a password system combining "rolling code" and DES encryption algorithm.

Description

Technical field [0001] The invention relates to an IC card electronic water meter for tap water, in particular to a tap water IC card electronic water meter that prevents power failure and loss of control, prevents tilt installation, and prevents IC card password theft. Background technique [0002] Nowadays, the popularity of water meters, especially IC card electronic water meters, has increased a lot. The use of IC card electronic water meters has not only brought a lot of convenience to users. In recent years, the technology of electronic water meters has made great progress, with the emergence of new technologies such as "anti-drip" and "water cut in arrears", which have greatly improved the water supply management level of water companies. influences. However, the existing IC card electronic water meter also exposes some problems during its use. [0003] Since the shut-off of the arrears water shutoff valve requires a certain amount of energy and shut-off time, the water me...
