Specific embodiment
The present invention provides a kind of underground electronic tag survey meter detecting fuel gas, and for making the purpose of the present invention, technical scheme and effect clearer, clear and definite, the present invention is described in more detail below.It should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Refer to Fig. 1 and Fig. 2, underground electronic tag survey meter, the fuel gas detection module 20 including the concentration for detecting fuel gas and the survey meter body 10 of the detected fuel gas that the present invention provides.
It follows that the survey meter that the present invention provides, can not only Underground electronic tag, the combustable gas concentration in surrounding can also be detected, so that while Underground electronic tag, the combustable gas concentration in surrounding can be detected, improve the efficiency of pipe detection.
Further, described fuel gas detection module 20 includes combustible gas detector, and described combustible gas detector includes a flexible feeler lever, and the end of described flexibility feeler lever is provided with high quick gas sensing hole.The flexible feeler lever of setting is so that described underground electronic tag survey meter can detect the combustable gas concentration in each corner live, very convenient.Described fuel gas includes other organic liquid steam such as methane, natural gas, ammonia, hydrogen, coal gas, propane, gasoline, coolant, ethanol, oxide, hydrogen sulfide, paint, solvent or diluent, industrial solvent, gaseous fuel.Described combustible gas detector adopts pumping or diffusion way that gas is sucked sensor detection, and described flexibility feeler lever can be lengthened with flexible pipe as needed.
The range of described combustible gas detector is 0-10000PPM.
Described underground electronic tag survey meter also includes display module 60, and described display module 60 is used for showing the concentration of fuel gas that fuel gas detection module 20 detects, and display gas concentration reaches the ratio of full scale in real time.USB interface for charging with transmission data is provided with described survey meter body 10.
Described underground electronic tag survey meter also includes exploring antenna 30, multiple Hall element（Magnetic field sensor）40 processing modules 50 being connected with multiple Hall elements 40.
See also Fig. 3 and Fig. 4, described exploring antenna 30, for producing magnetic field, in the magnetic field of generation, magnetic induction line, as shown in Fig. 3 dotted arrow, forms a magnetic induction area.Described exploring antenna 30 is coil antenna, after coil antenna energising, produces magnetic field.
Multiple Hall elements 40, on the face vertical with the axis of exploring antenna 30, are uniformly arranged with axis for the center of circle.Because multiple Hall elements 40 are uniformly arranged, centered on exploring antenna 30 axis, just on the basis of the north, each Hall element 40 with respect to exploring antenna 30 axis can shape in an angle, when the magnetic induction having Hall element to detect is abnormal, according to this Hall element, underground electronic tag 70 can be positioned, very accurately and convenient.And, the quantity of Hall element 40 is more, and positioning is more accurate.Preferably, the quantity of described Hall element 40 is 12.And in the present embodiment, as shown in figure 4, the quantity of described Hall element is 8,8 Hall elements represent eight orientation respectively：North（Before）, south（Afterwards）, west（Left）And east（Right）.
Preferably, described Hall element 40 is arranged on one end of exploring antenna 30；The face that multiple Hall elements 40 are located, keeps certain distance with one end of exploring antenna 30.So it is provided with beneficial to the volume saving underground electronic tag survey meter, improve detection accuracy.Depending on described certain distance can be according to the distance between the intensity in the magnetic field of exploring antenna 30 formation and Hall element 40.
Described processing module 50, for the magnetic induction detecting according to multiple Hall elements 40, judges the position of underground electronic tag 70.Specifically, described processing module 50 is used for the magnetic induction detecting according to multiple Hall elements 40, relatively draw the magnetic induction of detection Hall element the weakest, the orientation correspondence that Hall element the weakest for magnetic induction is located is shown as the position of underground electronic tag 70 in display module 60.Because underground electronic tag 70 influences whether the magnetic induction in magnetic induction area, therefore closely descend the magnetic induction that the Hall element of electronic tag 70 side senses can die down, described 50 need of processing module compare the orientation showing that magnetic induction Hall element the weakest by force is located, would know that the position of underground electronic tag, very convenient and practical.
Described display module 60, is additionally operable to the position of the underground electronic tag that Display processing module 50 draws, specifically, described display module 60 is stored with electronic chart, and described display module 60 explicitly descends the position of electronic tag on electronic chart.
Therefore, the underground electronic tag survey meter of the detected fuel gas that the present invention provides, by, on the face of vertical sounding antenna axis, uniformly arranging multiple Hall elements with axis for the center of circle.Take full advantage of electromagnetic induction principle, processing module only need to compare the orientation showing that magnetic induction Hall element the weakest by force is located, would know that the position of underground electronic tag, in 2 ~ 3 meters of underground electronic tag plan range effect very good, achieve automatic identification underground electronic tag, improve locating speed and precision, hand-held survey meter need not all around change position to detect.Carry out underground gas ductwork leakage patrol and examine or really occur leakage when, the present invention can check whether there is gas leakage by the positioning function of underground electronic tag survey meter in the surface of gas pipeline, very practical and convenient.
Further, described processing module 50 includes reference cell, voltage comparison unit and control unit.
Described reference cell, for obtaining direct north, on the basis of direct north.
Described voltage comparison unit, for comparing the voltage of the Hall element output being connected with processing module 50, draws the minimum Hall element of output voltage.The voltage of Hall element detection is lower, illustrates that magnetic induction is weaker.
Described control unit, for according to each Hall element of pre-setting with respect to benchmark（Direct north）Position relationship, specifically, according to each Hall element pre-setting with respect to benchmark（Direct north）Angle, draw the angle of the minimum Hall element of output voltage and benchmark, control display module to show corresponding for the position of underground electronic tag on electronic chart.
It can thus be appreciated that, described processing module only need to compare the voltage i.e. position of recognizable underground electronic tag of the Hall element output being arranged in each orientation of exploring antenna, circuit design that need not be complicated or logical operationss, simple and practical, described processing module can be made up of analog circuit, it is of course also possible to be MCU, the present invention is not construed as limiting.
