Abstract
The utility model relates to a leakage alarm comprising a detector and an alarm device, wherein the detector consists of an MSP430F149 single chip microcomputer, a reset circuit and a signal acquisition interface; the MSP430F149 single chip microcomputer is a microprocessor of a system and used for judging detected signals; program can be reset to be normal by pressing a reset button when having errors; the detector is fixed by a fixing bracket; the signal acquisition interface is connected with a shell of a household appliance by a signal acquisition line; the alarm device consists of a light-emitting diode and a buzzer; an alarm circuit consists of a buzzer, an NPN triode, a direct-current power supply and a power ground; and a leakage indicating circuit consists of a light-emitting diode, a signal acquisition interface, a power ground and a resistor. When leakage phenomenon happens, the light-emitting diode corresponding to the household appliance brightens and the buzzers can give out sound for alarming. The leakage alarm can detect whether a plurality of household appliances have leakage or not.
Description
[technical field]
Whether the utility model relates to a kind of leakage alarm, can detect a plurality of household electrical appliance and leak electricity.
[background technology]
The world today is to be the new technology revolution epoch of feature with the infotech, and microprocessor technology is the mainstay of modern information technologies.The incident of the electric leakage of household electrical appliance generation now happens occasionally, how can effectively prevent the Danger Electric shock risk that produces because of electric leakage? whether the microprocessor technology of having used the utility model can detect a plurality of household electrical appliance and leak electricity.
[utility model content]
The purpose of this utility model is to be used for detecting the alarm whether a plurality of household electrical appliance leak electricity.
The utility model is made up of pick-up unit and two parts of warning device.Pick-up unit is made up of MSP430F149 single-chip microcomputer, reset circuit, signals collecting interface.The MSP430F149 single-chip microcomputer is that the microprocessor of system is used for detected signal is judged.When program is made mistakes, press reset button and can make program recovery normal.Pick-up unit is fixed by fixed support.The signals collecting interface links to each other with household appliances shell by the signals collecting line.Warning device is made up of light emitting diode and hummer.Form warning circuit by hummer, NPN triode, direct supply, power supply ground.Form the electric leakage indicating circuit by light emitting diode, signals collecting interface, power supply ground, resistance.When leaky takes place, the lumination of light emitting diode corresponding, the hummer warning of can sounding simultaneously with these household electrical appliance.
[beneficial effect]
The beneficial effects of the utility model are that whether low in energy consumption, simple in structure, volume is small and exquisite, is convenient to install and use, can detect a plurality of household electrical appliance and leak electricity, and can effectively prevent the electric shock that takes place because of electric leakage.
[description of drawings]
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing 1 is circuit theory diagrams of the present utility model.
Accompanying drawing 2 is pictorial diagram of the present utility model.
