Description

Novel spirit level with the angles i detection function
Technical field
The present invention relates to geodesic surveys and the leveling device of engineering measurement field, especially one kind, and level survey can be improved The novel spirit level with the angles i detection function of accuracy of measurement, reliability and efficiency.
Background technology
Traditional leveling device is made of a spirit level and two levelling staffs.Spirit level is by object lens, focusing Lens, horizontal line of sight automatic compensator, spectroscope, cross wire division plate, eyepiece, figure reading electronic device and display and control terminal composition.It surveys Two levelling staffs are first respectively perpendicular to 2 points of A, B being placed on ground when amount, then spirit level is arranged in 2 points of A, B Between position, utilize spirit level telescope collimation axis after leveling(That is the line of crosshair intersection point and object lens optical center)The level of offer regards Line sights the absolute altitude numerical value for reading two levelling staffs respectively, and the difference of the high numerical value of institute's mark is the level height of 2 points of ground A, B Difference, if known elevation wherein, you can extrapolate the elevation of another point by height difference.Due to by Instrument Manufacturing Technique and air The factors such as environment influence so that telescope collimation axis when observation and there are an angles, fields of measurement to be commonly called as between horizontal plane For the angles i.The size at the angles i directly influences the precision, stability and reliability of the measurement of the level, is at present guarantee measurement of the level essence Degree, the following measure of generally use:(1)It needs to measure and adjust the angles i before the daily measurement of the level, the angles i of spirit level is made to be surveyed less than level It is poor to measure grade limit(Such as Chinese Industrial Standards (CIS):The angles first and second order leveling i limit difference is 15 seconds;Three, limit difference in the angles fourth-order leveling i is 20 seconds);(2)Make when measurement horizontal distance of the spirit level away from two levelling staffs it is equal or roughly equal, to eliminate or weaken the angles i Influence.But existing measure has that measurement working efficiency is low and measurement accuracy is low:It is measured before the daily measurement of the level And the angles i are adjusted, a large amount of energy and time of survey crew is often expended, it is relatively low to measure working efficiency;The daily measurement of the level The variation that can not find the angles i in journey in time leads to the reduction of measurement result precision;It such as finds that measurement accuracy is low and to ensure to measure Precision can only be abandoned having surveyed achievement, after redeterminating and adjusting the angles i, then carry out level from starting point to the end and resurvey so that measure Working efficiency reduces.In fact, the variation at the angles real-time dynamic monitoring i is to perplex a great problem of mankind's measurement of the level circle, simultaneously It is also the big technology barrier for restricting the intelligent measurement of the level.
201620816622.6 Chinese utility model patent of Patent No. discloses a kind of " level gage i angle monitoring device ", It is defeated equipped with spirit level collimation axis attitude signal sensor and the free pendulum mass displacement signal sensor of horizontal line of sight automatic compensator Go out and connect with data processing and controller, data processing and the output of controller connect with warning device, by being regarded to level Line automatic compensator carries out dynamic detection, realizes the real-time monitoring changed to level gage i angle, when the angles i of monitoring spirit level become Change and exceed scheduled threshold value, then automatic alarm.However, found in actually manufacture and use during, the patented technology there is also Following deficiency:(1)Realize that technical sophistication, manufacturing cost are high;(2)Direct Real-time and Dynamic Detection be not collimation axial light path the angles i Variation itself, but the displacement signal of the free pendulum mass of automatic compensator is detected, it needs further to be converted into pendulum mass displacement signal The angles i of light path change, and are related to calibration and the transfer problem of pendulum mass displacement, affect the precision and efficiency of detecting of the angles i variation.
