In standby, the pipeline includes water outlet equipment and waterway pipe, and the water outlet equipment may include shower, kitchen depotition cock, sit
Tank for excrement pan etc., the waterway pipe are the pipeline led to for water flow.As shown in Figure 1, including the following steps:
S100: judge whether be in off state with the water equipment of line segments connection to be measured, if then starting monitoring mould
Formula executes step S200；I.e. only when the water equipment with line segments connection to be measured is in off state, just starting monitors mould
Formula closes line segments to be measured, it is possible thereby to avoid influencing the just common water of water equipment.
S200: executing monitoring mode, within the monitoring period, closes the primary line segments to be measured at interval of preset time,
And when the line segments to be measured each time are closed, the first pressure value of pipeline inner wall is obtained.The monitoring period is according to reality
Household water situation is configured, such as in the morning and at night, can when household water opening of device is more and more frequent with water

The change rate of the first pressure value of road inner wall is more than upper limit threshold, then determines the quick leak of line segments to be measured；If in pipeline
The change rate of the first pressure value of wall is more than given threshold and is less than the upper limit threshold, then determines the line segments to be measured at a slow speed
Leak.The upper limit threshold can also carry out selection setting according to user preference.After obtaining curve according to first pressure value,
For being judged according to curvilinear motion curvature, as shown in Fig. 2, giving three curves indicates the change of first pressure value at any time
Change relationship.Obviously in no leak, at a slow speed leak and when three kinds of quick leak, the decrease speed of first pressure value has very big
Difference.It should be noted that line segments to be measured may be because of a variety of causes after closing, the airtightness of pipeline is not absolute,
So even the first pressure value detected may also have a little decline, but it declines degree in the case where being no leak
Much smaller than the decrease speed for having water leakage situation.
