Laser receiver, laser incident angle measurement system and method and attitude and motion state measurement method

Abstract

The invention discloses a laser receiver which comprises a multi-direction laser signal acquisition module, a laser signal processing module, a control processing module, a communication module and asix-axis or nine-axis sensor. The multi-direction laser signal acquisition module is used for acquiring laser signals in different directions; the laser signal processing module is used for processinglaser signals; the six-axis or nine-axis sensor is used for measuring angles of three mutually perpendicular axes of the laser receiver relative to the gravity direction of the earth, angles relativeto the due north of the geomagnetic field of the earth or angular motion data of the three axes; and the control processing module is used for analyzing the laser signal and data obtained by the six-axis or nine-axis sensor; and the communication module is used for transmitting the data processed by the control processing module to the outside. According to the invention, the laser incident anglecan be accurately measured, and the human body or equipment damage calculation precision is improved. The invention further provides a laser incident angle measurement system and method and an attitude and motion state measurement method.

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...
