摘要
为保证人体红外计数装置计数的准确性、可靠性和灵敏性,本文对控制程序的设计方法和过程进行详细的描述,包括信号采集、方向判断、数据处理和显示输出等。为满足实时性要求,采用中断方式编程。经实际测试,该程序工作状况良好。该控制程序的设计思路对广大电子爱好者有一定的参考价值。
In order to ensure accuracy, reliability and sensitivity of pyroelectric infrared sensor counter, design methods and process of its control program were described in detail, including signal acquisition, direction decision, data processing and display output etc. To meet requirements for real time, the interruption programming was used. The program worked well after testing. This design thinking of control program has certain referential value for the mass of electronic fans.
