Description
Technical field
The present invention relates to a kind of tap water water leakage device of monitoring and prevent, specifically is a kind of intelligent tap water leak-proof device.
Background technology
It is the troublesome problem of running into during people live that tap water leaks always, the running water pipe bursting by freezing can appear in winter, begin after thawing to leak, general resident will it's time to hand over water rate can find that just family leaks, also have to be exactly as toilet leak, pipeline recessiveness leaks, particularly pipeline recessiveness is leaked, when waiting you to find, often caused very big loss, leaked in a word and bring no small loss and trouble can for our life.How can find to leak, and solve seepy question the problem that has become people to be concerned about naturally in the very first time in the very first time.
Summary of the invention
The objective of the invention is to, a kind of intelligent tap water leak-proof device is provided, being used for monitoring, whether to belong to the normal life water still be improper leaking, and in time solve seepy question.To achieve these goals, the technical solution used in the present invention is: intelligent tap water leak-proof device, power circuit, the current monitoring device, the warning circuit that are installed in tap water master switch place that comprises tap water master switch, micro-control unit (Micro Control Unit is called for short MCU) control circuit, powers for the MCU control circuit, the electromagnetic valve that is installed in tap water master switch place; Wherein, the signal input part of the signal output part of current monitoring device and MCU control circuit, power circuit electric current are connected to the power input mouth of MCU control circuit, and power circuit further is connected with the power supply terminal of electromagnetic valve; The signal output part of MCU control circuit is electrically connected with warning circuit.
Optimally, comprise also with owner and carry out mutual global system for mobile communications (global system for mobile communications is called for short GSM) emission/receiving circuit that described GSM emission/receiving circuit is connected in the output of MCU control circuit.
Optimally, described current monitoring device comprises water flow sensing unit.
The invention has the advantages that at tap water master switch place the current monitoring device is installed, gather the current size at master switch place, and send the signal that the current that monitor produce to the MCU control circuit and judge whether to be normal living water use.How the MCU control circuit judges that the signal of sending here is normal water or leaks, the firstth, and by discharge, the discharge when discharge can substantially exceed resident's family and normally uses when the water pipe explosion, the MCU control circuit can detect the higher voltage amplitude; The secondth, by the time, to leak when recessiveness occurring, discharge judges that general domestic water can long-time continuous not use by the time of record current within normal range (NR), open continuously more than 45 minutes as the family water tap, then judges to belong to improper water.Thus, MCU control circuit voltage magnitude and the signal period (time) sent here according to water flow sensing unit judge whether to leak.Leak in case detect, the MCU control circuit just sends to warning circuit with alarm signal, reminds owner's tap water to reveal, manual-lock tap water master switch after owner obtains reporting to the police.If owner stays out, GSM emission/receiving circuit then passes through the note base station communication with owner so, and owner is by long-range transmission note, and indication MCU control circuit turn-offs electromagnetic valve, cuts off the tap water master switch.
Other features and advantages of the present invention will be set forth in the following description, and, partly from manual, become apparent, perhaps understand by implementing the present invention.Purpose of the present invention and other advantages can realize and obtain by specifically noted structure in the manual of being write, claims and accompanying drawing.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Description of drawings
Accompanying drawing is used to provide further understanding of the present invention, and constitutes the part of manual, is used from explanation the present invention with embodiments of the invention one, is not construed as limiting the invention.In the accompanying drawings: Fig. 1 is the present invention's intelligence tap water leak-proof device control principle figure.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.
As shown in Figure 1, present embodiment provides a kind of intelligent tap water leak-proof device.This device comprise the power supply of MCU control circuit, MCU control circuit power circuit, be installed in tap water master switch place current monitoring device, warning circuit, be installed in the electromagnetic valve at tap water master switch place; Wherein, the signal input part of the signal output part of current monitoring device and MCU control circuit, power circuit electric current are connected to the power input mouth of MCU control circuit, and power circuit further is connected with the power supply terminal of electromagnetic valve; The signal output part of MCU control circuit is electrically connected with warning circuit.Also comprise with owner and carry out mutual GSM emission/receiving circuit, described GSM emission/receiving circuit is connected in the output of MCU control circuit.The current monitoring device comprises water flow sensing unit.
The control chip of MCU control circuit is single-chip microcomputer STC12C5412AD, and single-chip microcomputer comprises clock circuit, reset circuit; Single-chip microcomputer is powered by the 5V DC source.The current checkout gear comprises water flow sensing unit, and water flow sensing unit is installed on the water supply pipe at tap water master switch place, and the signal output part of tap water sensor is electrically connected with single-chip microcomputer.The water of water supply pipe is through water flow sensing unit, and water flow sensing unit produces different output signals according to discharge.Discharge is big more, and the signal value of output is big more.Single-chip microcomputer is judged according to the signal that receives, if signal value illustrates that greatly to a certain degree discharge has exceeded normal use amount and got scope, the situation of leaking might occur.If the signal value size is normal, then single-chip microcomputer carries out timing to the time that signal continues, if signal is continuous more than 45 minutes, continuous 45 minutes seepages of tap water is described then, drainage might occur.When above-mentioned two kinds of situations occurring, single-chip microcomputer will be to the warning circuit instruction that gives the alarm.
