摘　　要：服务器能否正常运行,机房温度是首要问题。采用虚拟仪器的思想,将热敏电阻和555时基集成电路构成的振荡电路的输出作为声卡MIC的输入信号,通过DirectX编程对声卡的采样信号进行计算,实现温度的实时采样。这种方法硬件实现简单,充分利用了计算机声卡的模数转换能力,可以较为精确地实现机房温度的采样,然后将采样温度写入数据库,最后通过网页编程或手机短信等形式就可以实现机房温度的远程监控。Room temperature is the most important issue in server＇s normal work. Using virtual instrument thinking, thermistor and 555 time base oscillator circuit consisting of IC output as a MIC input audio signal through DirectX programming on the audio signal sampling, the realization of the real-time temperature sampling. Hardware implementation of this method simple,and making full use of the computer sound card analog-digital conversion capability and can be more precise achieve room temperature sampling,and then into the database, the final via the web programming or SMS,or other forms can be achieved room temperature remote monitoring.
