炉温自动测量仪是用于自动记录芯片烧结炉温度曲线,并监控烧结过程的装置。在微机测控系统中,A/D转换常用的方法是扩展一块或多块A/D采集卡。但由于该烧结炉温度变化缓慢,采用总线型A/D卡并不是最合适、最经济的方案。 本设计是以89C2O51单片机为核心。温度信号的A/D转换采用的是MAXIM公司的MAX187,它是12位串行A/D转换器,转换速度快、分辨率高、8脚DIP封装、体积小。数据存储采用串行快擦写存储器X25F128,
Automatic temperature measuring instrument is used to automatically record the chip sintering furnace temperature curve, and monitor the sintering process device. In the computer control system, A / D conversion is commonly used method is to expand one or more A / D acquisition card. However, due to the slow temperature changes in the sintering furnace, the use of bus A / D card is not the most suitable and most economical solution. The design is based on 89C2O51 microcontroller. The A / D conversion of the temperature signal is MAXIM MAX187 MAXIM Company, it is 12 serial A / D converters, conversion speed, high resolution, 8 pin DIP package, small size. Data storage using serial flash memory X25F128,
