Abstract

In this paper, an multi-channel acquisition device suitable for domestic Intelligent Programmable Logic Controller (IPLC) is developed. The GD32F407RE of GigaDevice is used as MCU control system and the AD chip SGM5208 of SGMICRO is used. The upper computer based on Loongson CPU realizes data interaction with the acquisition device through CAN communication. In the experiment, the precision current and voltage source is used to verify and test the developed multi-channel acquisition device. The device can realize the acquisition and transmission of DC analog 0-5V / 0-20mA , achieving a measurement accuracy of 0.1%. The developed multi-channel acquisition device achieves reliable operation in engineering applications. The influencing factors of measurement accuracy and real-time are analyzed, and the software is optimized. The device is designed based on domestic electronic components, which ensures the safety of the chip supply chain.
