2、漏电检测并报警无论是对家电还是对人体的自身安全都具有重要的意义,通过对漏电 的检测并报警,我们可以防患于未然,从而保护电器及人身财产安全。 关键词:单片机;AT89S51 ;报警器 III Abstract Along with technical and the electronic products widespread application, specially the electrical appliances popularization, at the same time which facilitates for us also follows the electrical a
3、ppliances to use electricity the security problem. The electrical appliances leak light to be possible to cause to be injured heavy to have the life danger.Divulging electric current, under the electrical appliances operating temperature divulging electric current is in particular 1 most can exactly
4、 reflect the practical work condition the security electrical system number; Also is one has safely to the human the direct influence electrical parameter.Because, when power line termination place, human body contact electric appliance outer covering, the electric appliance divulging electric curre
5、nt can flow to the earth through the human body, this can be our life is threaten.Therefore, regardless of the leakage examines and reports to the police is all has the vital significance to the electrical appliances or to human body own security, through and reports to the police to the leakage examination, we may prevent accidents before they occur, thus protects the electric appliance and the person property security.
