Abstract
A kind of absolute altitude, level of level measurement field copy survey instrument, comprise the microprocessor of soft tubule, pressure transducer, cable, waterproof ventilated membrane and band display screen, the inside filled with fluid of soft tubule, one end is connected with pressure transducer, and one end uses waterproof and breathable membrane closure in addition; Pressure transducer, by cable and the microprocessor signal transmission with display screen, finally shows with discrepancy in elevation form on a display screen, and the microprocessor of band display screen combines with the blind end with the soft tubule of waterproof ventilated membrane.The level that the utility model provides, absolute altitude are copied and are surveyed instrument and only need a people just can complete surveying work, and possess the advantage not affecting sight line by barrier, introducing electronic device, the discrepancy in elevation are transformed into electric signal difference, make reading, copy survey and more accurately facilitate.
Description
Technical field
The present invention relates to level measurement field, particularly a kind of absolute altitude, horizontal measuring instrument.
Background technology
The industries such as building, planning usually will copy survey level or absolute altitude, the method of the most ancient practicality of levelling utilizes the soft tubule of a segment length of both ends open also known as level tube, load a certain amount of water, general needs two people coordinates, and a people holds one end of soft tubule, ensures that level surface aligns original datum line, another people holds the other end of soft tubule, stand in the position needing to copy survey, put line according to this end level surface copying location, just ensure that two are in same level.And it is high to copy mark, be just through levelling, then copy the height measuring difference at new level surface up and down, or be first ferreted out wanted absolute altitude at master reference place, then use level tube levelling, absolute altitude guides to the place of needs.Measure with level tube, need to fill water at every turn, ensure to manage interior bubble-free, general needs two people's conjunction measurings, precision not too easily ensures, but can not by the impact of barrier in sight line.Afterwards, people had invented spirit-leveling instrument, utilize spirit-leveling instrument and mark post chi to coordinate to carry out absolute altitude, level copies survey.Each measurement also needs two people to coordinate, and spirit-leveling instrument will be selected suitable position prop up before measurement, level-off, then a people sees instrument, and a people takes mark post chi, carries out level, absolute altitude copies survey.Utilize spirit-leveling instrument to measure, all want level-off at every turn, also need two people to coordinate, sometimes also affect by barrier, need repeatedly again to prop up instrument.
Summary of the invention
For above-mentioned deficiency, the invention provides a kind of reading and more accurately facilitate, and only need a people can complete the instrument of absolute altitude, horizontal survey.In order to realize above-mentioned purpose, the present invention by the following technical solutions:
Principle of the present invention is, the stress that container bottom is subject to is directly proportional to the height of internal tank liquid.
Absolute altitude of the present invention, level copy survey instrument, comprise the microprocessor of soft tubule, pressure transducer, cable, waterproof ventilated membrane and band display screen, the inside filled with fluid of soft tubule, and one end is connected with pressure transducer, and one end uses waterproof and breathable membrane closure in addition; Pressure transducer pressure signal is become electric signal by cable by electric signal transmission to on the microprocessor of display screen, microprocessor and the pipe other end can combine, electric signal is shown with discrepancy in elevation form more on a display screen by microprocessor processes, and the microprocessor of band display screen combines with the blind end with the soft tubule of waterproof ventilated membrane.Survey wider to make to copy, in use soft tubule can need to be extended by the mode of grafting or shortened according to use.
Survey more convenient practicality to make to copy, be furnished with scale at the two ends of display screen, scale is marked with datum line, and two columns wordline.In order to make, measurement is more accurate is also provided with level tube on scale.In use in order to ensure the dirigibility operated, microprocessor and display screen also can separate, as long as guarantee display screen and soft tubule combine with one end of waterproof ventilated membrane and scale.
The invention has the beneficial effects as follows:
1. level, absolute altitude are copied survey work one people and just can be completed, and possess the advantage not affecting sight line by barrier.
2. introduce electronic device, the discrepancy in elevation is transformed into electric signal difference, makes reading, copy survey and more accurately facilitate.
Accompanying drawing explanation
Fig. 1 is absolute altitude of the present invention, level copies the structural representation surveying instrument;
Fig. 2 is the partial structurtes enlarged drawing of the present invention with display screen one end.
In accompanying drawing, the soft tubule of 1-; 2-pressure transducer; 3-cable; 4-waterproof ventilated membrane; 5-is with the microprocessor of display screen; 5a-display screen; 6-scale; 6a-datum line; 6b-digital line; 6c-digital line; 7-level tube.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
Absolute altitude, level copy survey instrument, comprise soft tubule 1, pressure transducer 2, cable 3, the microprocessor 5 of waterproof ventilated membrane 4 and band display screen, the inside filled with fluid of soft tubule 1, and one end is connected with pressure transducer 2, and one end uses waterproof ventilated membrane 4 to close in addition; Pressure transducer 2 passes through cable 3 transmission of signal with the microprocessor 5 of band display screen, and the microprocessor 5 of band display screen combines with the blind end with the soft tubule 1 of waterproof ventilated membrane 4.Soft tubule 1 can use the mode of grafting to extend or shorten.The two ends of the display screen 5a of the microprocessor 5 with display screen are furnished with scale 6, and scale 6 is marked with datum line 6a, and two columns wordline 6b, 6c.In order to measure accurately, scale 6 is also provided with level tube 7, the display screen 5a in the microprocessor 5 of band display screen can be separated.
When copying survey, one people can finish the work, to locate in place with sensor side fixed placement, ensure that this end destroies the position of survey lower than the datum line provided and needs, the hand-held other end with display screen, first the datum line on scale is alignd with the actual datum line provided, numeral on display screen is set to zero or other numeral needed, then display screen is moved on to the position needing to copy survey, if mark is high, by the direct reading of datum line alignment measurement point on scale, if the level of copying, absolute altitude, it can be made to reach required level by moving display screen, absolute altitude is rule again, also certain limit can be reached by moving display screen, required level is marked again by scale, absolute altitude.
