光储充电站多接口数据采集和故障录波装置的设计

Design of Multi-interface Data Acquisition and Fault Recording Device for Optical Storage and Charging Station

光储充电站的数据采集装置应用指标主要包括接口兼容性、批量处理数据能力和数据传输速率几个方面,本系统从批量高速数据传输方面出发,采用FPGA作为主控核心单元,设计一种多接口数据传输装置,可以兼容多种通信电气接口,特别是串口采用高速电平转换芯片,并采用非标准波特率;数据采集装置中设置数据阈值,对故障数据进行记录。该装置主要发挥数据传输和故障数据保存的作用。

Data acquisition device of optical storage and charging station mainly includes interface compatibility, batch data processing ability and data transmission rate. Starting from batch highspeed data transmission, this system uses FPGA as the main control core unit to design a multiinterface data transmission device, which can be compatible with many kinds of communication electrical interfaces, especially the serial port uses high-speed level. Conversion chip and nonstandard baud rate are used. Data threshold is set in data acquisition device to record fault data. The device mainly plays the role of data transmission and fault data preservation.
