摘要
设计了一种新型陶瓷窑炉温度测量方案,该方案选用与8051单片机完全兼容的高性能单片机STC12LE5A60S2作为主控制器,采用冷端补偿热电偶至数字输出转换器MAX31855测量温度。介绍MAX31855与STC12LE5A60S2芯片SPI总线通信接口原理,给出了MAX31855的模块化驱动程序,成功地实现MAX31855的驱动和陶瓷窑炉温度测量。
A new scheme has been designed to measure the temperature of ceramic kilns. We choose as the main control STC12LE5A60S2, a high-performance MCU that is completely compatible with 8051 MCU. The measuring tool is MAX31855, a transformer which can compensate at the cold end and export the thermocouple signal. The principles of SPI trunk communication interface of MAX31855 and STC12LE5A60S2 chip are introduced, and the modularized drivers of MAX31855 are designed, through which the temperature of ceramic kilns can be measured.
