Description

Swing data acquisition device

Technical Field

The utility model belongs to the technical field of electronic information, especially, relate to a swing data acquisition device.

Background

At present, two methods are available for measuring the inclination angle of a high-rise tower building (such as a communication iron tower), namely visual measurement and theodolite measurement, in practical application, the visual measurement only depends on the experience of observers to qualitatively judge whether the iron tower is inclined, and a specific inclination numerical value cannot be obtained; if the theodolite is used for observation, the requirement on the measurement environment is high, for example, no shielding object exists around the measurement iron tower, the visibility is high under the current weather condition, and the like. More importantly, the two methods cannot be monitored in real time and are only carried out in the spring and autumn by polling, effective data comparison, analysis and data mining cannot be obtained for the swinging of the daily iron tower, and whether the iron tower has potential danger or not is further unknown. The inclination and collapse of the iron tower are a gradual accumulation process (except serious geological disasters such as earthquake and the like) under most conditions, so a new technology is needed to monitor the iron tower in real time and collect effective data so as to analyze, compare and mine the data.

Through the above analysis, the problems and defects of the prior art are as follows:

(1) whether the iron tower is inclined or not is qualitatively judged by depending on the experience of observers, and a specific inclination value cannot be obtained.

(2) And when the theodolite is used for observation, the requirement on the measurement environment is higher, if no shielding object exists around the measurement iron tower, the visibility is higher under the current weather condition, and the like.

(3) The manual detection is time-consuming and labor-consuming, the theodolite is used for measuring the inclination angle of the iron tower, the measurement time of one iron tower is at least about one hour, and in addition, other times are added, a group of engineering teams can measure 6 iron towers at most every day, and if the total number of the iron towers in one city is 2000 (actually most of the iron towers are more than the number), the group of engineering teams can measure all the iron towers in one year.

(4) The existing iron tower monitoring mode cannot carry out real-time monitoring, effective data comparison, analysis and data mining cannot be obtained, and potential danger of the iron tower cannot be known.

The difficulty in solving the above problems and defects is:

(1) how to accurately and efficiently measure the inclination angle of the iron tower.

(2) Real-time data acquisition problems.

(3) And (4) a data transmission mode.

The significance of solving the problems and the defects is as follows:

(1) the method replaces the method for manually measuring the inclination angle of the iron tower, is improved into automatic sensing, and saves labor and time cost.

(2) The continuous monitoring of the inclination angle of the iron tower is realized, and huge iron tower swing information data are accumulated.

(3) Stable transmission is realized, and the maintenance cost is reduced.
