基于labview的串口通信

基于生产者与消费者的多通道数据采集与存储(Multichannel data acquisition and storage based on producer and consumer)

本程序根据调幅原理，产生一个频率可在 0-10Hz 范围内改变的正弦信号作为调制信号，产生一个频率为 100Hz 的正弦信号作为载波信号，m 是调幅波的调制系数，可在 0-4 之间变化，进行AM调制，效果良好，可以方便初学者观察m变化时，超调与不超调的样子。

LabVIEW客户端第二界面，是实现LabVIEW TCP通信的客户端第二个界面。(The LabVIEW client second interface is the second interface of the LabVIEW TCP communication client.)

labview开发的实时地图调用，调用百度地图API(baidu di tu API ,shi shi dingwe i)

用实验方法测试RLC串联谐振电路的幅频特性曲线。当正弦交流信号的频率f改变时，电路的感抗、容抗随之而变.取电路电压U0作为响应，当输入电压Ui幅值维持不变时，在不同信号频率的激励下，测出U0之值，用LabVIEW程序完成频谱分析和滤波，变换等信号处理，即可测出RLC串联电路的谐振频率，(Amplitude-frequency characteristics experimentally tested RLC series resonant circuit curve. When changing the frequency f of the sinusoidal AC signal, the circuit inductance, capacitance change with Take circuit voltage U0 as a response when the amplitude of the input voltage Ui unchanged, signals at different excitation frequencies, the measured value U0, the process is complete spectrum analysis using LabVIEW and filtering, transform signal processing, can be measured RLC series circuit resonant frequency,)

说明：  该程序主要实现了，在labview中远程访问数据库的功能。(it can help us to query the database on line.)

电子爱好者们经常希望测试自己的音频设备如声卡、碟机、功放、音箱等的性能指标，却苦于没有价格高昂的专业测试设备而无从下手，设计制作时也无法进行必要的测试指导。有些CD碟提供了测试信号，如著名的“雨果发烧碟（一）”、“My Disk”等，《无线电》也曾推出音频测试CD。但CD信号的精度有限，而且没有操作系统的配合，测量、记录和分析都很不方便。(Electronic fans often want to test their audio devices such as sound cards, CD, amplifier, speakers and other performance indicators, but have no specialized test equipment without the high price the start, can not carry out the necessary tests to guide the design of production. Some CD discs provide a test signal, such as the famous Hugo Audiophile CD (a) , My Disk and so on, Radio has launched an audio test CD. CD signal but the accuracy is limited, and there is no tie, measurement, recording and analysis of the operating system is very inconvenient.)
