Abstract

The invention relates to an angle measurement system based on a high-precision wire-type coded sensor, in particular to a device for measuring the rotation angle of an indirect gun barrel. Its function is to accurately measure the rotation angle of the artillery barrel projected on the horizontal plane without structural modification of the indirect artillery equipment, and to eliminate the influence of the "empty back" of the artillery's own structure. It is composed of a wire length measuring mechanism, a calculation circuit and a calibration circuit; the wire length measurement mechanism includes a wire encoder, a fixing and guiding device, and a level measuring device; the data communication between the calculation circuit and the wire encoder is performed through the RS422 interface, and the calculation The core control chip of the circuit is a microprocessor based on the ARM-Cortex3 core; the calibration circuit also uses the ARM-Cortex3 series microprocessor, which is connected to the solving circuit through the RS232 interface, including a set of operation keyboards and display digital tubes.

Description

technical field

[0001] The invention relates to an angle measurement system based on a high-precision wire-type coded sensor, in particular to a device for measuring the rotation angle of an indirect gun barrel. Its function is to accurately measure the rotation angle of the artillery barrel projected on the horizontal plane without structural modification of the indirect artillery equipment, and to eliminate the influence of the "empty back" of the artillery's own structure. Background technique

[0002] A photoelectric encoder is a common sensor used to measure the rotation angle of a mechanism. When the sensor is used to measure the rotation angle of the cannon barrel, it is necessary to modify the cannon equipment and link the encoder with the cannon shaft. This method has a simple algorithm and high measurement accuracy, but the measuring equipment cannot be easily applied to the actual cannon. Realize the assessment of the artillery operation process. Another method ...
