Abstract

The invention relates to a servo control system and method for a multi-field thermal imager, the system includes a power filter module, a power conversion module, an asynchronous communication module, a main control module, a main control reset module, a motor drive module, and a high-precision sensor position signal Modem module, signal conditioning module, reference voltage generation module, connector and limit switch input module. The present invention adopts the main controller whose performance meets the requirements as the core control device, the motor driver with ultra-small volume, and the high-precision position signal acquisition module, and realizes the position servo precise control of the four-way motor.

Description

technical field [0001] The invention relates to a servo control system, in particular to a multi-field thermal imager servo control system, and also to a control method thereof. Background technique [0002] There are many kinds of infrared thermal imaging cameras according to different functions; in terms of the number of fields of view, they are divided into single-field thermal imaging cameras, dual-field thermal imaging cameras, three-field thermal imaging cameras and continuous zoom thermal imaging cameras. instrument. Compared with single-field thermal imagers and dual-field thermal imagers, three-field thermal imagers integrate large, medium, and small fields of view, and can realize observation, tracking, and aiming functions. Compared with the continuous zoom thermal imager, the design, processing, assembly and servo control of the three-field thermal imager are relatively easy to realize, and have the advantages of good imaging quality and short field of view conv...
