Background technology
When residential building designs, design side focuses primarily on the emphasis of design in some residential building automatic building control systems, and right
The balcony metope for being built into residential building building main body lacks corresponding electronic assistance aids.
However, when roof leaking situation occurs for balcony metope, because metope inner space is closed, people can not understand inside
Whether concrete condition and flowing water trend, can not particularly understand specific leak region and leakage point, cause people are uncertain to leak
Rain, the particular location of roof leaking is not known, so as to do the leaking-stopping measure to make mistake, causes plugging operation to be worked hard but to no avail.
Therefore, it is necessary to a kind of balcony leakage point detection scheme, can the accurate automatic start leak water detdction mechanism when rainy,
Specific leak region and leakage point are accurately detected, and notifies balcony resident nearby in time, so as to improve balcony leak stopping efficiency.
