Laser receiver, system and method for measuring laser incident angle, and method for measuring attitude and motion status

Abstract

The invention discloses a laser receiver, which comprises a multi-directional laser signal acquisition module, a laser signal processing module, a control processing module, a communication module and a six-axis or nine-axis sensor; the multi-directional laser signal acquisition module is used for collecting laser beams from different directions signal; the laser signal processing module is used to process the laser signal; the six-axis or nine-axis sensor is used to measure the angle of the three perpendicular axes of the laser receiver relative to the direction of gravity of the earth, the angle relative to the true north of the earth's magnetic field, or three The angular motion data of the axis; the control processing module is used to analyze the laser signal and the data obtained by the six-axis or nine-axis sensor. The communication module is used to transmit the data processed by the control processing module to the outside. The invention can accurately measure the laser incident angle and improve the calculation accuracy of human body or equipment damage. The invention also provides a laser incident angle measurement system and method as well as attitude and movement state measurement methods.

Description

technical field [0001] The invention relates to a signal receiver, specifically a laser receiver capable of accurately calculating the damage of a human body or equipment, a laser incident angle measurement system and method, and a posture and movement condition measurement method, belonging to the field of military training equipment. Background technique [0002] At present, actual combat training is developing in the direction of intelligence, and lasers are usually used instead of ammunition for actual combat training. The specific method is to install laser transmitters on weapons and laser receivers on personnel and equipment. During confrontation training, the weapon emits a coded laser beam, and if the laser receiver installed on the personnel and equipment receives the coded laser beam, it will be judged as being hit. [0003] On February 19, 2019, the Chinese invention patent CN109357567A disclosed a method for controlling the effective range of direct-pointing we...
