Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photoelectric products, in particular to a photoelectric product detection and measurement equipment. BACKGROUND

[0002] As a ranging sensor, the laser radar is commonly used in the fields of unmanned vehicles and robots. As a core perception sensor of L3+ level automatic driving, the laser radar continuously bears wideband random vibration (5-2000Hz) and mechanical impact (>50g) during the driving of a vehicle. Therefore, when testing the laser radar, the influence of multi-physical field coupling factors needs to be considered, covering multiple aspects such as optics, mechanics, electronics, environment and algorithm. However, the traditional single-axis vibration table (such as an electromagnetic Shaker) can only simulate single-axis linear vibration and cannot reproduce the spatial multi-degree-of-freedom compound vibration in the real vehicle driving, resulting in distorted test scene. Moreover, the vibration-temperature-humidity coupling effect lacks synchronous testing capability, and multiple independent tests are required, prolonging the test cycle by 60%.

[0003] At present, the vibration force direction provided by the traditional test and measurement equipment is relatively fixed, which cannot simulate the real vibration environment, and the test result is not accurate enough. Moreover, the coupling degree of multiple physical fields is low, and multiple independent experiments are required to complete the detection. SUMMARY

[0043] A water mist system is arranged on the front side of the laser radar test piece 19. The truss 21 with adjustable height is arranged in front of the laser radar test piece 19 to generate water droplets and water mist, so as to simulate complex external environments for testing the laser radar test piece 19.

[0044] The vibrator simulates mechanical vibration of different frequencies through different rotating speeds, and cooperates with the vibration platform to simulate a complex vibration environment.

[0045] The technical scheme solves the phenomenon that the vibration force direction provided by the traditional test metering equipment is relatively fixed, a real vibration environment cannot be simulated, and the test result is not accurate enough, the technical scheme forms a vibration platform capable of swinging in multiple directions by providing alternating variable magnetic repulsion forces in four directions, so as to generate vibration in multiple directions and simulate a multi-directional vibration working condition, and is used for optical stability and signal accuracy of the laser radar test piece 19 during use, and cooperates with the vibrator to simulate inherent mechanical vibration at different rotating speeds, and can provide a complex external environment of water droplets and water mist in multiple directions, so as to provide a complex and changeable test environment.
