Problems solved by technology

At present, the traditional test method is mainly the contact three-dimensional sensor test method. This method uses a large number of displacement sensors to attach the spray boom structure body, and uses a multi-channel signal processor to fit the dynamic characteristics of the spray boom. Contact test, poor safety, high cost of use, limited test range

Embodiment Construction

[0029] In order to clarify the technical purpose and working principle of the present invention, the present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 2 The shown is a sprayer boom dynamic characteristic test system based on binocular image acquisition, which is composed of a control computer 1, a six-degree-of-freedom vibration platform 6, a binocular image acquisition device, and node markers.

[0031] The spray rod 5 to be tested is fixedly installed on the six-degree-of-freedom vibration platform 1 through a detachable rigid connection structure. The six-degree-of-freedom vibration platform 6 is connected to the control computer 1, generates corresponding vibrations according to the motion excitation control signal output by the computer 1, and transmits the vibrations to the spray boom 5 to be tested through the rigid connection structure, simulating field operations. The co...

Abstract

The invention discloses a sprayer spray boom dynamic characteristic test system and method based on binocular image acquisition. The test system comprises a control computer, a six-degree-of-freedom vibration platform and a binocular image acquisition device. A spray boom to be tested is mounted on the six-degree-of-freedom vibration platform; the six-degree-of-freedom vibration platform is connected with the control computer, can generate corresponding vibration according to a control signal output by the computer and transmits the vibration to the spray boom to be tested; and the binocular image acquisition device comprises a synchronous controller and two image acquisition devices arranged in a co-vertical-line manner. The two image acquisition devices are connected with the synchronouscontroller, and are used for collecting images synchronously according to the control signal; and the synchronous controller is connected with the control computer. The test system and method can quickly and accurately test dynamic characteristics of the sprayer spray boom when the sprayer spray boom works in different fields, have the advantages of non-contact operation, high safety and high true reduction degree, and are suitable for being applied widely.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a system and method for testing the dynamic characteristics of sprayer booms based on binocular image acquisition. Background technique [0002] The boom sprayer is the most widely used model in the field plant protection operation. The wide boom sprayer has a positive effect on improving the efficiency of pesticide application and reducing the damage to crops during the operation. During the field operation of the boom sprayer, the external excitation generated by the undulation of the road surface will cause the movement displacement of the boom structure such as rolling, swinging and vibration. The dynamic characteristics of the boom directly affect the uniformity of spray deposition distribution, the service life of the boom structure and the safety of field operations, and are an important basis for the design, production, operation parameter setting and maint...
