Abstract

The invention relates to a drinking water anti-leaking intelligent controller which is formed by a micro processor, a timing circuit, an interlock, a display circuit, a pulse generating circuit, an address decoder, a parallel interface, a door dog, an input keyboard and a switch value output circuit, wherein the micro processor is a core device which is connected with the display circuit by the interlock and is connected with the input keyboard and the switch value output circuit by the interface; the digital value input interface is connected with the timing circuit to output the signal; the timing interface is connected the pulse generating circuit; the strobe signals of the address decoder are separately connected with the timing circuit, the interlock, the display circuit, the door dog and the parallel interface; the reset end of the door dog is connected the micro processor.

Description

technical field [0001] The invention relates to a tap water anti-running intelligent controller, which is used for real-time monitoring of running water accidents caused by accidents such as forgetting to close the valve of the tap water, bursting of the tap water hose, falling off of the water injection valve of the washing machine, etc., and closing the valve in time to prevent running water . Background technique [0002] Running water will not only bring huge losses to oneself, but also often bring disaster to neighbors, affect neighbor relations, and even go to court. Existing a kind of purely mechanical anti-running water device on the market at present, it is to rely on the floating whereabouts and self-locking after the water is stopped, and the principle of manual reset is required after the water comes in again. Its biggest disadvantage is that it cannot prevent accidental water leakage. Contents of the invention [0003] In order to avoid unnecessary losses ca...
