摘要
电话语音查询与控制系统,它既能对用户所有可访问的数据进行查询,也可以完成对大型电机(如热水器、空调、电冰箱)进行重点的温度监测和远程控制,以此优化管理,提高工作效率。
本文设计了电话语音查询与控制系统,本系统是由上位机(PC机)、下位机(PIC16F54单片机)、电话语音卡、执行机构、外线(普通市话线路)和内线等组成。电话语音查询部分是由用户通过电信网拨打系统热线连接电话语音卡或者内线直接连接电话语音卡,从而检测振铃或摘机、录放音、收发DTMF码等功能,经过上位机的数据库给用户提供所查询的结果。电话语音控制系统是基于PIC16F54单片机来控制执行机构的运行。
本系统还具有良好的可扩展性,比如对产生小数据量的设备进行远程监测的能力;自动远程报警的功能;还能及时提醒此时该进行哪项工作等等,因此本系统能够有效地管理监控中心某些工作的进度。

Abstract
The telephone pronunciation inquiry and the control system can not only carry on the inquiry to the data which might be enquired by the users,but it can also plish the key temperature monitoring and the remote control on the the large-scale electrical machinery such as the water heater, the air conditioning, and the electric refrigerator in order to optimize the management and improve work efficiency .
This article has designed the telephone pronunciation inquiry and the control system,which posed by the superior machine (pc machine), the lower position machine (the PICI6F54 monolithic integrated circuit), the telephone sound card, the implementing agency, the outwire (ordinary public opinion line) and the inside connection and so on. The telephone pronunciation inquiry is partially a kind of telephone sound card which is connected through the work dialing system hot line by the users or the inside line directly, thereby it can detect ringing or pick, tape recorders, send and receive DTMF code, and other functions and provide the inquiry result to the users by the superior machine database. The telephone voice control system controls the implementation of the operation based on the PIC16F54 microcontroller.
This system also has the good extendibility, for instance, the ability to have a remote detecting about the equipment producing the small quantity data, remote automatic alarm function, pair process carrie
