Description
Technical field
The present invention relates to a kind of measurement of the level sighting distance display device.
Background technology
Measurement of the level is used aspect engineering construction very extensively.In the middle of leveling work; In order to slacken the influence of level gage i angle error, earth curvature, atmosphere refractive power to measurement of the level; Spirit-leveling instrument is equated with distance between the levelling pole of front and back as far as possible, and the different brackets geometric leveling difference of adjusting the distance has different requirement, wherein; Second-order levelling requires the front and back sighting distance difference in the survey station to be not more than 1m, and three, the sighting distance difference is not more than 3m before and after the fourth class.At present; It mainly relies on the surveyor to judge the distance between levelling pole and the spirit-leveling instrument according to experience visual estimation (or pacing); Measure longitudinal separation according to the spirit-leveling instrument optical ranging method then; In case when ruler distance in front and back differs the poor demand limit that surpasses regulation, need once more (or repeatedly) to move levelling pole, so that the difference of the distance between front and back levelling pole and the instrument is poor less than the limit of regulation.Compare with optical ranging; Electronic level also only obtains outside the bigger raising in range finding speed and reliability; Its working method does not change; When front and back distances does not satisfy instrument, also need move levelling pole and satisfy related request through (or repeatedly) once more, still needing after each the moving find range once more compares.Range finding is that point-to-point (between instrument and the levelling pole) mode is carried out in the present measurement of the level; Can't obtain the distance size between the three in real time; Instrument can be found range after must aiming at levelling pole, needs to aim at once more the comparison of finding range after each the moving, and so continues till meeting the demands; This working method will expend the too many time aspect adjustment, influenced the work efficiency of measurement of the level greatly.
Summary of the invention
The purpose of this invention is to provide a kind of measurement of the level sighting distance display device, make the surveyor can confirm oneself rational position fast, to improve the work efficiency of measurement of the level.
The sighting distance real-time displaying device comprised microcontroller, wireless transmitter, display, wireless distance finding circuit, module and warning device is set before and after the present invention was achieved in that measurement of the level; Display links to each other with microcontroller, and the wireless distance finding circuit links to each other with microcontroller, and the wireless distance finding R-T unit links to each other with microcontroller; Warning device links to each other with microcontroller; Module is set to link to each other with microcontroller.
Through the wireless distance finding circuit, the distance between real-time surveyor's level and the levelling pole also is shown on the indicator screen, and display can show needed all data.
Except the phase mutual edge distance that can measure three party in real time; Also comprise the setting of auditory tone cues warning device and correlation technique parameter; Be provided with like the setting of measuring distance permissible value size, longitudinal separation difference size; When the distance between surveyor and the instrument surpasses the different brackets required distance, warning device warnings of can sounding, the prompting surveyor is apart from transfiniting; After a side and instrument distance is confirmed; An other side is in case move to when meeting the demands with the former range difference; Warning device also can send other a kind of audible alarm, and prompting surveyor longitudinal separation is near equating that indicator screen also can show the difference of longitudinal separation simultaneously; So at work, survey crew need not when walking, to watch indicator screen.
The present invention is simple in structure; Production cost is low; Be convenient for carrying, can be installed on spirit-leveling instrument and the levelling pole, can let surveyor three parts know the distance between front and back levelling pole and the spirit-leveling instrument in real time; Can confirm the installation position of levelling pole or spirit-leveling instrument apace, improve the work efficiency of measurement of the level effectively.

Embodiment
Embodiment:
As shown in Figure 1, measurement of the level sighting distance display device comprises microcontroller, wireless transmitter, display, wireless distance finding circuit, display, module and warning device is set; Display links to each other with microcontroller, and the wireless distance finding circuit links to each other with microcontroller, and the wireless distance finding R-T unit links to each other with microcontroller; Through the wireless distance finding circuit, measure real-time distance display between spirit-leveling instrument and the levelling pole on display screen, display screen can show needed all data.
Warning device links to each other with microcontroller; Like Fig. 3, when transfiniting apart from difference between levelling pole 2 and the spirit-leveling instrument 1, warning device can send alarm sound, the prompting surveyor.
Module is set to link to each other with microcontroller; For the measurement of the level of different brackets, each item poor demand limit is different, through module is set parameters is provided with, and makes this device be used for the leveling work of different brackets.
The wireless distance finding signal that uses is the ultra wideband radio signal of UWB, and the sighting distance precision reaches 0.6m, can satisfy the requirement of two, three, four measurement of the level.
