What are the aspects of the software design of the infrared thermometer?
System main program flow circle
Infrared thermometer The main program of the system designed in this subject should be initialized first, open the interrupt, set the 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 to carry out Displays the temperature value.
System serial port sending and receiving program design
Focus on introducing the sending and receiving procedures of the communication circuit designed by this system. The communication circuit designed in this system completes the sending and receiving between the single chip microcomputer and the computer through RS-485, and allows sending and receiving by selecting the serial port mode, and then judges whether to complete the sending and receiving according to TI and RI. Utilize assembler to write the sender program of this design.
In the same way, the receiving program of the system can also be written according to the program block diagram.
in conclusion
Infrared temperature measurement breaks the traditional temperature measurement mode. It has fast response, high measurement accuracy, high reliability, wide range, and non-contact measurement, so it is not easy to be damaged. In addition, in recent years, China's infrared product market has developed rapidly and steadily. The market share of a few foreign companies has increased rapidly, and they have already occupied a considerable advantage in the Chinese market. This market development trend will definitely affect China's market. The development of infrared technology and industry plays a positive role in promoting, which will definitely stimulate and accelerate the advent of infrared technology products with complete Chinese independent intellectual property rights, and will also bring a broader infrared product application market. Therefore, the application of infrared thermometers is bound to become more and more extensive, with broad market prospects and economic benefits.
