background technology:
along with developing rapidly of China's economic construction, improving constantly and all other causes flourishing of living standards of the people, in last 20 years of 20th century, China's per capita household electricity consumption has turned over one and has turned over, but electrical fire also increases severely thereupon, architectural electricity fire is as a kind of disaster, and under the situation developing rapidly in economy, the loss of causing to national wealth and the people's life security also grows with each passing day.According to statistics, fire more than 80% be building fire, electric leakage is the key factor that causes building fire, for guaranteeing the safety of people's lives and properties, Electric Leakage Fire Alarm just becomes the improving constantly of increasingly sophisticated and living quality of one of design content important in high-rise civil building design power utilization environment, impel the technology content of low-voltage power supply and distribution system equipment constantly to promote, the raising of security level also impels leakage fire supervisory system to turn to flexible, intelligent Centralized Monitoring mode.The electrical fire monitoring device that existing market occurs only has warning function, can not prevent that fire from occurring, the loss that is merely able to alleviate fire.
summary of the invention:
the purpose of this utility model is to provide a kind of electrical fire monitoring device for fire-fighting Internet of Things.
above-mentioned object realizes by following technical scheme:
a kind of electrical fire monitoring device for fire-fighting Internet of Things, its composition comprises: residual current transformer, hygrosensor, described residual current transformer, described hygrosensor are connected with the amplifier being arranged in monitoring detector, described amplifier is connected with AC/DC change-over circuit, described AC/DC change-over circuit is connected with A/D converter, described A/D converter is connected with central processing unit A, described central processing unit is connected with output circuit, and described output circuit is connected with the input circuit being arranged in watch-dog.
the described electrical fire monitoring device for fire-fighting Internet of Things, described watch-dog comprises housing, in described housing, there is described input circuit, described input circuit is connected with central processing unit B, and described central processing unit is connected with audible-visual annunciator, light-emitting diode display, control signal output circuit, storer, usb circuit respectively.
