摘要
介绍了一种基于MLX90620红外阵列热电堆传感器的多点动态温度监测系统,详细阐述了系统的实现方法及设计方案。系统以STM32F103VET6作为核心控制器,以MLX90620作为温度传感器,控制器与MLX90620通过I2C总线进行数据通信,并通过UART接口将数据传输给上位机软件,软件可记录并实时显示温度数据,同时描绘已选监测温度点的温度变化曲线。实验表明,系统可同时监测目标区域内的64个温度点的温度变化情况,工作可靠,非接触式测温方式使得操作简单,便于安装使用。
Based on MLX90620 infrared array thermopile sensor,a multi-point dynamic temperature monitoring system was designed and implemented. The principle and implementation of this system were described in detail. The microcontroller STM32F103VET6 was used as the core,the chip MLX90620 was used as the temperature sensor,controller and MLX90620 communicate via the I2 C bus,and the microcontroller transmitted data through the UART interface to the software on host computer. The software can record and real-time display temperature data,while depicting temperature curve of the selected pixels. Experiments show that the system can simultaneously monitor 64 temperature points in the target area,and non-contact temperature measurement methods make operation simple,easy to install and use.
