What are the aspects of software design of infrared thermometer?
1System main program flow circle
The main program of the system designed for this project of infrared thermometer should first initialize, enable interrupts, set interrupt priority, set the initial value of the timer, then start the A/D converter, call the interrupt service program, and finally call the dynamic display program. Display temperature value.
1.1 System serial port sending and receiving program design
Focus on introducing the sending and receiving procedures of the communication circuit designed in this system. The communication circuit designed in this system uses RS-485 to complete the transmission and reception between the microcontroller and the computer. By selecting the serial port mode, transmission and reception are allowed, and then based on TI and RI, it is judged whether the transmission and reception are completed. Use assembly program to write the sending program of this design.
In the same way, the system's receiving program can also be written according to the program block diagram.
2Conclusion
Infrared temperature measurement breaks the traditional temperature measurement mode. It has fast response, high measurement accuracy, high reliability and wide range. It is non-contact measurement and therefore not easy to be damaged. In addition, China's infrared product market has developed rapidly and steadily in recent years. The market share of a few foreign companies has increased rapidly and has already occupied considerable advantages in the Chinese market. This market development trend will definitely have an impact on China's market. The development of infrared technology and industry has played a positive role in promoting and will surely encourage and accelerate the emergence of infrared technology products with completely independent intellectual property rights in China. It will also bring about a broader application market for infrared products. Therefore, the application of infrared thermometers will inevitably become more and more widespread, with broad market prospects and economic benefits.
