Description
Technical field
The utility model relates to leak source detection and location system, is specifically related to a kind of leak source detection and location system that is used for fluid pipeline.
Background technique
The liquid conducting pipes that in industry, uses usually can because of the corrosion or physical damage cause leakage.Leak and not only bring economic loss, also might influence production safety, therefore monitor the leakage situation of pipeline in real time, confirm that the leak position is just necessary.
The leak source detection and location method of now having announced has following several kinds:
1. flow equilibrium method, under the normal condition, the flow that the flow of entrance will equal to export, just less than the flow of outlet, this method only is applicable to the detection that big flow leaks, and locatees the position of leakage point at the flow that sends outlet when leaking.
2. pressure difference method, under the normal condition, the pressure of entrance and the pressure of outlet are only poor to be definite value, the just leakage that takes place of explanation when pressure difference takes place by bigger the variation, this method sensitivity is low, and can't locate the position of leakage point equally.
3. suction wave detection method; The transient negative pressure ripple of in fluid, propagating when utilizing pipeline to leak suddenly detects, and the suction wave through the pipe ends that captures calculates, thereby judges whether to leak; Because situation is complicated in the pipeline; Disturb greatly, be difficult to realize the accurate seizure of suction wave during practical application, practice has little significance.
The model utility content
The purpose of the utility model promptly is to overcome the deficiency of existing technology, provides a kind of simple in structure, can accurately locate the leak source detection and location system that is used for fluid pipeline of leak source position.
The purpose of the utility model realizes through following technological scheme:
The leak source detection and location system that is used for fluid pipeline; It comprises pressure transducer and the flow transducer that is arranged at pipe ends; And evenly be arranged on a plurality of flow transducers between the pipe ends; The output of all pressure transducers and flow transducer all is connected with data acquisition module, and data acquisition module is connected with upper-position unit through communication module, and upper-position unit is connected with alarm module.
Data acquisition module comprises analog-digital converter and PLC controller, and the input of analog-digital converter is connected with the output of pressure transducer and flow transducer, and the output of analog-digital converter is connected with the PLC controller.
Communication module is GPRS communication module or wireless set, if adopt the GPRS communication modes, requires upper-position unit also to support GPRS, and both sides are through the mobile communications network swap data.If adopt the general radio communication mode, then require upper-position unit also to be provided with wireless set, both sides transmit and receive data through wireless set.
Upper-position unit is a PC.
Alarm module is an audible-visual annunciator.
The advantage of the utility model does, and is simple in structure, low to the required precision of sensor, and what can realize the leak source location of different accuracy according to the quantity of flow transducer.
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 fluid pipeline; It comprises pressure transducer and the flow transducer that is arranged at pipe ends, and evenly is arranged on a plurality of flow transducers between the pipe ends, and the output of all pressure transducers and flow transducer all is connected with data acquisition module; Data acquisition module is connected with upper-position unit through communication module, and upper-position unit is connected with alarm module.Data acquisition module comprises analog-digital converter and PLC controller, and the input of analog-digital converter is connected with the output of pressure transducer and flow transducer, and the output of analog-digital converter is connected with the PLC controller.Communication module is GPRS communication module or wireless set.If adopt the GPRS communication modes, then upper-position unit is also supported GPRS, and both sides are through the mobile communications network swap data.If adopt the general radio communication mode, then upper-position unit also is provided with wireless set, and both sides transmit and receive data through wireless set.Upper-position unit is a PC.Alarm module is an audible-visual annunciator.
The working principle of the utility model is following:
Sensor is passed to data acquisition module with detected pressure signal and flux signal; In data acquisition module; Signal is passed to the PLC controller and handles after analog-digital converter converts digital signal to, the PLC controller is passed to upper-position unit with the signal of finishing dealing with through communication module, and upper-position unit judges whether to leak after calculating; If generation is leaked then is sent alarm signal through alarm module, and leak source position, location.
When pipeline point took place to leak, the pressure of pipe ends descended, and the flow of inlet increases, and the flow of outlet reduces, and upper-position unit can judge whether to leak through above principle.After leaking, every adjacent two the detected flow values of flow transducer of upper-position unit contrast if certain adjacent two detected flow value of flow transducer is only poor bigger, can confirm that then leakage point is positioned at this two flow transducers.The quantity that increases flow transducer can improve Location accuracy.
