Abstract
The invention provides a kind of method and device of measuring the discrepancy in elevation, form measuring head by transparent straight pipe base of the band scale of opening etc.By a flexible pipe two measuring heads are communicated with, conducting liquid is injected in the inside.Because the liquid level in two measuring heads is equal all the time, so as the benchmark of measuring wantonly 2 discrepancy in elevation.This method is different from the optical instrument method of spirit-leveling instrument.This device also has bar resistor, voltage table etc., the high difference of point-to-point transmission can be changed into electric potential signal, both can measure the discrepancy in elevation of any point-to-point transmission of certain limit immediately, and the discrepancy in elevation that also can measure point-to-point transmission for a long time automatically changes.
Description
The present invention relates to a kind of discrepancy in elevation method of the discrepancy in elevation and device, particularly a kind of non-optical instrument, any point-to-point transmission of energy measurement certain limit between 2 of measuring on the ground.And no matter point-to-point transmission has the obstacle of ignoring to exist, and the discrepancy in elevation variation that can measure point-to-point transmission for a long time automatically, or the promotion servo control mechanism carries out the automatic control of levelling bench.
The instrument of the point-to-point transmission discrepancy in elevation mainly is a spirit-leveling instrument on the existing measurement ground, and main method is to utilize the optical instrument principle, and it requires point-to-point transmission can not look obstacle, and the general cost of spirit-leveling instrument is higher, can not monitor the point-to-point transmission discrepancy in elevation for a long time automatically and change.
The purpose of this invention is to provide a kind of new measuring method and device, can measure the discrepancy in elevation of the point-to-point transmission of looking obstacle, and can accomplish that the long-term discrepancy in elevation of measuring automatically changes.Install simple and reliable, cheap.
Invention is achieved in that by the diameter of two openings identical transparent straight pipe and a hollow hoses and constitutes a special linker, is carved with long measure on straight tube, is equivalent to a rule.In the straight tube bottom one base is arranged, straight tube can be placed on the tested point vertically.Straight tube having rule and base is called " measuring head ".Interior dress conducting liquid is when being placed on two measuring heads on two points to be measured, and according to law of connected vessels, the liquid level in the measuring head (straight tube) is inevitable equal.Like this, just can measure the distance of each point respectively, and then try to achieve 2 the discrepancy in elevation and come with the liquid level of two measuring heads as benchmark.Owing to be equipped with the bar resistor with the straight tube parallel axes in the measuring head straight tube, it and conducting liquid constitute one " variable resistor system ".With external voltage table, power supply etc.Form a circuit, make in the measuring head liquid level with respect to the straight tube scale, that is the variation of resistor stripe position, electric signal become.Because the relative variation of liquid level is corresponding one by one with the point-to-point transmission discrepancy in elevation, just can be reflected the discrepancy in elevation and variation thereof by electric signal at 2.
Details of the present invention with the following Examples and accompanying drawing give to further specify.
Fig. 1 is a kind of concrete structural drawing of the present invention.
With reference to Fig. 1, (1) is transparent, upper end open, and there is the long straight tube of an arm lower end, and scale is arranged on it.(2) be bar resistor.(3) be conducting liquid.(mercury or sodium hydroxide solution etc.) (1), (2) and base (4) formation measuring head.(5) be flexible pipe, the special linker of formation that is communicated with two measuring heads, make two liquid levels in the measuring head equal all the time, be in same level.(6) be a metal joint, conducting liquid and instrument (7) are connected.(7) instrument is the voltage table of internal electric source.
When two measuring heads are put on the tested point, the scale value that the liquid level indication is certain is because two liquid levels are equal, so the difference of the scale value on two measuring heads is 2 the discrepancy in elevation.
Bar resistor (2), by conducting liquid and external wire, and power supply, voltage table constitute circuit shown in Figure 2.
With reference to Fig. 2, (1) is power supply, and (2) are bar resistor, (4) be voltage table, (3) be equivalent to two in the straight tube liquid level, play a part the potentiometer moving contact.Fig. 2 circuit is a circuit of surveying current potential on the bar resistor.When measuring head is placed on the different measurement point of height.Liquid level in two measuring heads will be different with respect to the position of its rule, that is with respect to the position difference on the bar resistor, and always an end is as rising, and then the other end descends, and is perhaps opposite.Like this, the high difference of point-to-point transmission is just corresponding one by one with the potential value that records.Like this, the high difference of point-to-point transmission becomes electric potential signal.Just can carry out long-term automatic measurement, perhaps go to drive certain servo-drive system, carry out the automatic control of level table etc. with this signal.
The present invention can be used for doing construction account, mountain slide monitoring etc.
