浅谈利用VB编程实现模拟信号对讲机系统的自动录音

Discussion on realizing automatic recording of analog signal interphone system by VB programming

为了解决选煤厂生产过程中普遍使用的模拟信号对讲机系统语音、音频、录音功能的缺陷,近几年新出现的数字式信号对讲机系统集成了语音音频录音功能,但价格昂贵,且与目前主流用户的模拟式对讲机系统不兼容,带来模拟式对讲机系统升级费用投资巨大的问题。根据模拟对讲机系统的语音音频信号特点,利用计算机声卡采集对讲机音频信号,通过VB编程对音频信号进行自动触发录音和保存,实现普通模拟信号对讲机系统语音音频录音功能。详细阐述了方案的软件、硬件组成、功能及特点。

At present,the digital signal intercom system widely used in coal preparation plant has voice and audio recording function,but the system was not compatible with mainstream users,and the upgrade cost of analog intercom system is huge.According to the characteristics of voice and audio signals of analog intercom system,the voice and audio signals of intercom were collected by computer sound card.Through VB programming,the audio signal was automatically recorded and saved,and the voice and audio recording function of common analog signal intercom system was realized.The composition,function and characteristics of the scheme were described in detail.
