Detailed Description
In order to make the technical solutions of the present application better understood by those skilled in the art, the technical solutions of the present application will be clearly and completely described below in conjunction with the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It is noted that the term "comprising" in the description and claims of the present application is intended to cover a non-exclusive inclusion, e.g. a method comprising a list of steps is not necessarily limited to those steps explicitly listed, but may include other steps not explicitly listed or inherent to such methods. The embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail with reference to examples.
Example 1
In this embodiment, an indoor water leakage detection method is provided, which includes the following steps:
step 1, closing a water inlet end and opening a water outlet end in a water pipe network in a room to be detected
The purpose of this step is to drain the water in the room, so the water source can be cut off by closing the water inlet end in the room, and part of the water in the pipe network can be drained by opening the water outlet end of the outlet water, and considering the position of the water outlet end in the room (generally on the wall) and the conventional laying method of the pipe network (the conventional pipe network is more buried under the bottom surface), so a certain amount of water still exists in the pipe network after the operation is finished, in order to solve the above problems, the step 2 is performed after the operation is finished
Step 2, after the water outlet ends do not discharge water, closing all the water outlet ends, ventilating the room, and continuing for a period of time
Through above-mentioned step, can make indoor steam evaporation rapidly behind the mode of adopting ventilation, also can discharge rapidly in ponding in the wall body and the pipe network, in order to realize the complete discharge of ponding etc., this step should last to be no less than 24 hours, simultaneously in order to reach best effect, also can go on in the higher period of temperature such as summer, perhaps can open the quick evaporation of air conditioner heating or heating device etc. realization steam in indoor, should be indoor closed after this step is accomplished, thereby avoid outside steam to the influence of testing result, after this step, carry out step 3
Step 3, uniformly placing humidity sensors on two sides of the water pipe network in the room to acquire humidity data, establishing a three-dimensional graph of the humidity distribution of the room, and continuously acquiring data
Because the indoor water outlet points or water accumulation points surround the indoor pipe network, in the embodiment, the humidity sensors surround the uniform part of the water pipe network, and particularly, most of the water outlet points are at the joints of the pipe network, in the embodiment, the corresponding humidity sensors are placed at the joints of the pipe network, meanwhile, in the embodiment, in order to avoid the complicated circuit influence on the detection process, the humidity sensors are connected with the controller by adopting Bluetooth, so that the complexity of equipment can be reduced, the emission and the use of the equipment are facilitated, an indoor three-dimensional map is established after the arrangement of the sensors is completed, meanwhile, the positions and the collected data corresponding to the humidity sensors are added in the map, so that the corresponding three-dimensional map is established, the visual observation of the humidity in the room is realized, the position and the time label are added to the collected data, and the data statistics and analysis in the later period, it is convenient to judge, and after the step is finished, the step 4 is carried out.
Step 4, simultaneously opening the water inlet and outlet ends until the water outlet end discharges water, closing the water outlet end, and maintaining the state for a period of time
The purpose of the step is that after the influence of accumulated water is eliminated in the step 1, the pipe network is filled with water and pressurized, so that a water leakage point can leak water, the water leakage point inevitably drives humidity change after water leakage, so that corresponding abnormal data can be collected, statistical analysis is facilitated, and the detection accuracy is improved, wherein the point with abnormal humidity data obtained in the step is the water leakage point (the so-called data abnormality is the humidity data with larger difference compared with the data measured in the steps 1 to 3, and the position of a humidity sensor corresponding to the humidity data is the water leakage point); in order to avoid the influence of the water scattered at the water outlet end on the detection result, the water scattered at the water outlet end in the step is quickly wiped to avoid the influence on the result, and the next step 5 is carried out after the step is finished
Step 5, closing the water inlet end and opening the water outlet end, and continuously acquiring data
The purpose of this step lies in detecting the ponding point, because the abnormal point that step 4 detects the gained is the collection of water leakage point and ponding point (water leakage point and ponding point may close to or may be far away, because the position of ponding is the cavity position mostly, and this position probably keeps away from the pipe network), therefore, for accurate detection ponding point, adopt in this step to close the end of intaking again and open the end of water outgoing, thereby make the water leakage point no longer leak water or the very big reduction of ability of leaking, and ponding point because of there being ponding, its humidity change degree is far below the change degree of water leakage point within a certain time, therefore, the data abnormal point that detects in this step is very big probably the ponding point, carry out step 6 after this step is accomplished
And 6, analyzing the humidity data, wherein water leakage or water accumulation points are formed when the data are abnormal.
The step of analyzing the data can be divided into two sections, wherein one section is the abnormal condition of the humidity data in the time period of the analyzing step 4 to obtain the set positions of the water accumulation points and the water leakage points, the other end is the abnormal condition of the humidity data in the time period of the analyzing step 5, according to the transformation trend of the abnormal condition, the water leakage points are formed when the humidity change trend is larger in the same time period, and the water accumulation points are formed when the humidity change trend is slower.
Further, step 5 also includes rapidly wiping off water spilled from the water outlet end for accurate experimental results.
Further, for accurate experimental results, the duration of step 4 is not less than 6 h.
Further, the duration of step 5 is not less than 6h for accurate experimental results.
