Abstract
The utility model discloses a leak point detection and location system for a purified water conveying pipeline. The system comprises multiple acoustic sensors arranged on the pipeline, wherein the output end of each acoustic sensor is connected with the input end of an amplifier, the output end of the amplifier is connected with the input end of a digital-analogue converter, the digital-analogue converter is provided with a clock chip, and the output end of the digital-analogue converter is connected with the input end of a communication module; and the system further comprises a central processing unit and multiple branch processors, wherein the communication module is connected with the branch processors, and the branch processors are connected with the central processing unit through a communication line. The central processing unit is connected with an alarm device and a displayer. The system has the advantage that the whole system is located at the outside of the pipeline and cannot contact the purified water in the pipeline, so that the purified water cannot be polluted.
Description
Technical field
The utility model relates to leakage detecting and positioning device, is specifically related to a kind of leak source detection and location system that is used for the purified water conveyance conduit.
Background technique
The pipeline of carrying liquid is embedded under the ground situation at the end at the long perhaps pipeline of pipeline owing to aging or breakage can be shone into leakage, and leakage is difficult to find.Can use purified water in some fields, if carry the pipeline of purified water to leak, not only can shine into economic loss, purified water is polluted, influence is used.Detection facility based on flow equilibrium method or pressure difference method commonly used all places sensor and carries out detection and location in the pipeline, but purified water is very sensitive to polluting, and places the equipment in the pipeline that purified water can't be used.Now also be not applicable to the leak source detection and location system of purified water conveyance conduit.
The model utility content
The purpose of the utility model promptly is to overcome the deficiency of existing technology, and a kind of leak source detection and location system that is used for the purified water conveyance conduit is provided, and it has overcome the deficiency that can pollute purified water based on the detection facility of flow equilibrium method or pressure difference method.
The purpose of the utility model realizes through following technological scheme:
The leak source detection and location system that is used for the purified water conveyance conduit; It comprises a plurality of sonic sensors that are arranged on the pipeline; The output terminal of sonic sensor is connected with amplifier input terminal; The output terminal of amplifier is connected with the input end of analog-digital converter, and analog-digital converter is provided with clock chip, and the output terminal of analog-digital converter is connected with the input end of communication module;
Also comprise central processing unit (CPU) and a plurality of minutes path processors, communication module is connected with dividing path processor, divides path processor to connect through the communication line central processing unit (CPU).
Central processing unit (CPU) is connected with display device with warning device.
Communication module is wire communication module or wireless communication module.
The advantage of the utility model is that whole system is positioned at the outside of pipeline, not with pipeline in purified water contact, can not pollute purified water.
Description of drawings
Fig. 1 is the structured flowchart of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further, the protection domain of the utility model is not limited to the following stated.
As shown in Figure 1; The leak source detection and location system that is used for the purified water conveyance conduit; It comprises a plurality of sonic sensors that are arranged on the pipeline, and the output terminal of sonic sensor is connected with amplifier input terminal, and the output terminal of amplifier is connected with the input end of analog-digital converter; Analog-digital converter is provided with clock chip, and the output terminal of analog-digital converter is connected with the input end of communication module; Also comprise central processing unit (CPU) and a plurality of minutes path processors, communication module is connected with dividing path processor, divides path processor to connect through the communication line central processing unit (CPU).
Central processing unit (CPU) is connected with display device with warning device.
Communication module is wire communication module or wireless communication module.
The working principle of the utility model is following:
Sonic sensor is passed to amplifier with the acoustic signals that collects; Amplifier is passed to analog-digital converter to the acoustic signals that acoustic signals will amplify after will amplifying then; Analog-digital converter is digital signal with certain frequency with the analog signal conversion that receives under the control of clock chip; And pass to the branch path processor through communication module, the corresponding branch path processor of each sonic sensor.What the branch path processor will receive compares to signal and known thresholding waveform, if the signal that receives surpasses the thresholding waveform then shows leakage has taken place.Divide path processor that leakage information is sent to central processing unit (CPU), CPU calculates the leak position, and it is passed to the display device demonstration, and central processing unit (CPU) also activates warning device.
