Description
Technical field
A kind of electronic surveying instrument of the utility model is specifically related to that a kind of utilization is measured cable, lead and shows the measuring appliance of lead basic parameter through LCD output.
Background technology
Measuring instrument commonly used to cable, lead, bus in the electrical engineering at present is slide calliper rule, and slide calliper rule can be divided into mechanical calliper and electronic type slide calliper rule.Digimatic calipers has that reading is directly perceived, easy to use, the characteristics of diverse in function.It mainly is made up of chi body, sensor, control arithmetic section and digital display portion.According to the multi-form division of sensor, digimatic calipers is divided into raster pattern and capacitance-grid type two big classes.Raster pattern, digimatic calipers are to adopt grating as sensor, and chi frame displacement is carried out computing with the variation input control section that the variation of Moire fringe converts electric signal to, by digital display portion The measured results show are come out again, and the people is come into plain view.Such digimatic calipers precision is higher, but power consumption and volume are bigger.The capacitance-grid type digimatic calipers is adopt to hold grid as sensor, and the electric signal that utilizes the variation of electric capacity between fixed polar plate and the movable plate electrode to send carries out computing with its input control arithmetic section, by digital display portion The measured results show is come out again.This digimatic calipers relatively simple for structure, power consumption is less, but its measuring accuracy is a little less than the raster pattern digimatic calipers.The digital display portion of existing slide calliper rule mainly adopts light emitting diode and two kinds of forms of liquid crystal display, and they cut both ways: although the power consumption of light-emitting diodes form of tubes is more, volume is also bigger, and Presentation Function is relatively poor, and it is more clear to show.And the power consumption of liquid crystal display form is less, and Presentation Function is better, but is not so good as the clear of light-emitting diodes form of tubes.What most of slide calliper rule were generally commonly used is the digimatic calipers of liquid crystal display.
Above-mentioned measurement slide calliper rule belong to the universal measurement instrument; Cable, lead, bus are measured, can only be measured length and external diameter, electric material basic parameter commonly used is not carried out necessary demonstration and prompting; Especially the measurement of lead class; Because the mask method that various countries adopt is different, use habit is different in addition, is nominally mm like China's lead
2The measured diameter as a result that comes out also will calculate conversion, in daily use, to line footpath, current-carrying capacity, the safe carrying capacity of tested cable, lead; Environment for use, material etc. also must be carried out the handbook classified inquiry, have brought bigger inconvenience for habitual the use.
Summary of the invention
The deficiency that exists for the measurement slide calliper rule that solve above-mentioned prior art; The purpose of the utility model provides a kind of cable conductor measuring appliance; Can measure, convert tested cable, lead; And accomplish data call, Chinese shows, and it is simple in structure, cost is low, volume is little, power consumption less, easy to install, environmental suitability is strong.
The technical scheme that the purpose of realization the utility model is taked is: on existing sliding measurement slide calliper rule basis, show that with being fixedly connected the slide calliper rule that are integral on the moving chi of slide calliper rule assembly, communication adapter and cable show assembly; Slide calliper rule show the detecting unit that the band capacitive sensor is housed in the assembly, and detection signal is connected to the slide calliper rule display screen and the defeated interface of communicating by letter respectively; Communication adapter connects slide calliper rule and shows that assembly and cable show the communication interface of assembly; Cable shows that the communication interface of assembly connects single-chip microcomputer, and single-chip microcomputer connects LCD display and user program data-carrier store respectively.
Described slide calliper rule show that assembly and cable show that the communication interface of assembly adopts the RS-232 communication interface, and communication adapter adopts the RS-232 communication adapter, and single-chip microcomputer is connected with LCD display through the display driver unit.
The measurement bayonet socket place of moving chi of described slide calliper rule and slide calliper rule scale has embedded the alloy paster.
Show the diameter of the detection of assembly through digital display calliper to tested lead; Export the digital display calliper display screen respectively to and carry out diameters demonstration and communication interface; The signal of communication interface is sent to the communication interface that cable shows assembly after handling through communication adapter, enters into single-chip microcomputer again, and the database data that calls in the program data memory of family through single-chip microcomputer calculates, inquires about, compares; Store GB cable data in the user program data-carrier store; When the cable data were effective, its cable data showed via display driver circuit, LCD display, and Chinese demonstrates the information such as material, service condition of wire diameter and current-carrying table parameter and lead simultaneously; Can show the function button on the assembly shell through cable, carry out page turning, select to check.
The beneficial effect of the utility model is: simple in structure, cost is low, volume is little, power consumption less, easy for installation, environmental suitability is strong, resolution is high, wide dynamic range, demonstration reading are directly perceived, easy to use, diverse in function, data presentation quick and precisely wait; Have stronger promotional value, can be widely used in manufacturing works, become cable, lead type selecting, maintenance, servicing operations in distribution, electrical production, the electric engineering construction.
