Problems solved by technology

However, there are some problems in this positioning: for example, the resistance value of the induction line may change with the change of environmental parameters such as ambient temperature. At the same time, due to the large amount of electromagnetic interference in the system environment, the current and voltage signals are prone to generate noise during transmission. Cause inaccurate detection results, unable to accurately locate
On the other hand, since two sensing lines and auxiliary lines such as signal lines and detection lines are required, and devices for detecting voltage and current need to be installed separately, the overall cost is relatively high

Embodiment 1

[0021] One of the specific implementations of a water leakage detection and positioning system and positioning method of the present invention, such as figure 1 As shown, it includes: a power supply 4, an auxiliary power line 3 connected to the negative pole of the power supply 4 at the front end, a positioning induction line 1 and a positioning power line 2 connected to the positive pole of the power supply 4 at the front end, and the tail end of the positioning induction line 1 is connected to the positioning power supply Line 2 tail end; also includes a total current detection unit (not shown) for real-time acquisition of power supply 4 output total current I and acquisition and location of power line 2 current I 2 The positioning current detection unit (not shown in the figure) and the data processing unit (not shown in the figure) that automatically obtains the detection data of the total current detection unit and the current of the positioning power line 2 and automatica...

Embodiment 2

[0026] Such as figure 2 As shown, the second specific embodiment of a water leakage detection and positioning system and positioning method of the present invention, the main technical solution of this embodiment is the same as that of embodiment 1, and the features not explained in this embodiment are adopted in embodiment 1 explanation, and will not repeat them here. The difference between this embodiment and Embodiment 1 is that it also includes an auxiliary induction line 6, the auxiliary induction line 6 is connected to both ends of the auxiliary power line 3, and the positioning induction line 1 is connected to the auxiliary induction line 6 at the water leakage point 5 through the auxiliary induction line 6. The power line 3 is turned on. Since most of the existing detection cables have a structure of double induction wires, the existing cables can be conveniently used by adopting the connection method, and it is only necessary to slightly improve the connection metho...

Embodiment 3

[0028] Such as image 3 As shown, the third specific embodiment of a water leakage detection and positioning system and positioning method of the present invention, the main technical solution of this embodiment is the same as that of Embodiment 1, and the features not explained in this embodiment are adopted in Embodiment 1 explanation, and will not repeat them here. The difference between this embodiment and Embodiment 1 is that the front end of the positioning sensing line 1 is connected to the negative pole of the power supply 4 , and the front end of the auxiliary power line 3 is connected to the positive pole of the power supply. The positioning method of this embodiment is similar to that of Embodiment 1, and only needs to be adaptively modified according to the connection relationship.

Abstract

The invention relates to the technical field of water leakage detection and in particular relates to a water leakage detection positioning system and a water leakage detection positioning method. The system comprises a power supply, a positioning induction line, a positioning power supply line and an auxiliary power line, wherein the positioning power supply line is connected to two ends of the positioning induction line; the front end of the positioning induction line is connected with one pole of the power supply; the front end of the auxiliary power line is connected with the other pole of the power supply; the tail end of the positioning power supply line is separated from the tail end of the auxiliary power line; the positioning induction line and the positioning power supply line are not conducted with the auxiliary power line in a water leakage-free state, and the positioning induction line is conducted with the auxiliary power line in a water leakage state through a water leakage point. According to the detection method, the current flowing through the positioning induction line reaches an auxiliary induction line through the water leakage point is detected, so that the water leakage point is positioned by combining the length L of the positioning induction line. According to the system, the positioning accuracy and reliability of the water leakage point are effectively improved, and the cost of the system is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of water leakage detection, in particular to a water leakage detection and positioning system and device. The positioning method is accomplished by establishing a functional module framework and controlling the computer system by computer program instructions. Background technique [0002] With the rapid development of informatization and intelligent construction, a large number of power transmission and signal transmission cables are laid in information computer rooms and intelligent buildings. Or water leakage causes cable short circuit and signal transmission failure, resulting in equipment system malfunction or equipment damage; long-term water accumulation can also cause equipment corrosion or other serious accidents. How to accurately find the location of water leakage and take measures such as maintenance and plugging in time is the key to reducing equipment damage and ensuring normal operation of eq...
