Description

A measuring device for measuring the height of an instrument

technical field

The utility model relates to a height measuring device in surveying and mapping engineering, in particular to a measuring device for measuring the height of an instrument.

Background technique

At present, when measuring the height of the instrument, a steel tape is generally used for measurement. When the height of the instrument is erected high or the control point is located in the protection well, it is difficult to measure the height of the instrument by one person alone; Due to the influence of the frame and the instrument, the steel ruler cannot be straightened during the measurement process, and the read value is equivalent to the distance of a curve. Even if the average value of multiple measurements is taken, there will be influences of measuring methods and reading errors. Obviously, using the traditional method to measure the height of the instrument is not only inconvenient, but also has unnecessary error effects. Therefore, there is a need for a device capable of accurately measuring the height of the instrument, so as to facilitate use and improve the accuracy of the measurement results.

Contents of the invention

The purpose of this utility model is to overcome the shortcomings in the above-mentioned prior art and provide a measuring device for measuring the height of an instrument. The measuring device effectively overcomes the disadvantages of large error and inconvenience in measuring the height of the measuring instrument in the prior art, and can measure the height of the instrument conveniently and accurately by using a retractable measuring rod in combination with a laser distance measuring module.

The utility model is realized in this way: the measuring device for the height of the measuring instrument includes a telescopic measuring rod, a housing, a display screen and a distance measuring system, the telescopic measuring rod is installed at the middle position of the top of the housing, and the display screen is installed at the top of the housing. In the upper part, the ranging system is installed in the lower part of the housing.

The telescopic measuring rod is a slender rod that passes through the hole at the top of the tripod. The length is a fixed value. It is stretched to the longest when in use, and can be retracted when not in use. It is easy to carry. It functions as a measuring instrument (or base) bottom to The instrument height measures the fixed height of the device.

The display is used to display the height of the instrument.

The ranging system is used to measure the height of the instrument height measuring device to the ground point. The ranging system includes a microcontroller, a setting module, a display module, a power supply and a laser ranging module; a setting module, a display module, a laser ranging module and The power supply is respectively connected to the microcontroller; the microcontroller is used to control the entire laser ranging system; the setting module is used to set the measuring position of different types of instruments to a fixed height at the bottom of the instrument (or base); the power supply supplies power to the entire device; the laser The ranging module is used to measure the height of the device from the ground point.

The utility model has the advantages of simple structure and low production cost, and effectively overcomes the disadvantages of large height error and inconvenience of measuring instruments in the prior art. The utility model can be used in combination with a telescopic measuring rod and a laser distance measuring module, and can conveniently and accurately measure Measure the height of the instrument.
