Design of Wireless Temperature Measurement and LED Lattice Display System for Ceramic Kiln

陶瓷窑炉温度的测量是陶瓷工业生产技术核心,利用nRF2401无线通信模块将窑炉温度数据进行无线传送,16×64LED双色点阵远距离实时显示窑炉温度,实现窑炉温度测量极少对陶瓷烧制生产中装坯和产品出窑的干扰。MAX31855是冷端补偿热电偶至数字输出转换器,在测温范围0℃至+1300℃内精度达±6℃,软件设计采用分段温度补偿计算子程序后测温精度优于±1℃。该陶瓷窑炉无线温度检测及LED点阵显示系统,具有较高测量精度,在复杂的陶瓷烧制现场使用,有着很好的实用价值。

Temperature measurement of a kiln is one of the key technologies in ceramic industry. The temperature data can be transmitted by wireless communication module nRF2401, and simultaneously double-colored lattice 16×64LED will display the temperature of a kiln in real time in the distance. Such measurement will hardly interfere with the loading and unloading of a kiln in the course of production. MAX31855 is a cold-junction compensated thermocouple-to-digital converter with the thermocouple accuracy of less than ±6℃ for temperatures ranging from 0℃ to 1300℃, and the accuracy can be increased to less than ±1℃ through the sectional temperature compensation by a subprogram. The wireless temperature measurement and LED lattice display system for ceramic kiln are accurate when used in firing, so they have good practical value.
