IC card water control charging device

Abstract

The invention discloses an IC card water control charging device which comprises a controller, an electromagnetic valve and a flow sensor. An IC card reading module is arranged on the controller. The electromagnetic valve and the flow sensor are electrically connected with the controller. The electromagnetic valve and the flow sensor are installed on a tap water pipe. The electromagnetic valve is sleeved with a shielding cover. A reed pipe device and a buzzing alarm device are installed on the flow sensor. The reed pipe device and the buzzing alarm are electrically connected with the controller. The IC card water control charging device is simple in structure, convenient to install, capable of resisting disassembling and magnesium, and capable of effectively avoiding a water stealing event.

Description

technical field [0001] The invention belongs to an IC card water control billing device, in particular an IC card water control billing device designed to prevent water theft. Background technique [0002] At present, in schools and public places, most of the water resources are charged, that is, whoever uses the water pays, and the charging medium of the charging controller is mainly an IC card. Most of these IC card water control meter have the following defects: [0003] At present, the IC card water control meter on the market basically controls the on-off of the solenoid valve to control the use of tap water or hot water. However, when the solenoid valve is usually disturbed by strong magnetism, even if a strong magnet is placed on the top of the solenoid valve, the solenoid valve can be attracted by the strong magnetic energy to be in a conduction state, and the solenoid valve will lose its control function, so that water can be used for free. [0004] The metering d...

Problems solved by technology

[0004] The metering device used in the metering IC meter is based on the Hall sensor. When the Hall sensor receives strong magnetic interference, the Hall sensor will fail and cannot detect the flow rate.

Usually the billing controller calculates the water consumption by detecting the pulse of the Hall sensor. When the data line of the Hall sensor is disconnected or disconnected or the Hall sensor is artificially removed from the installation position on the water pipe, the meter The bill controller also cannot detect the flow, which also causes the meter to be unable to bill and use free water, which leads to the occurrence of water theft incidents
