摘　　要：固定电话应用广泛,管理固定电话话务信息的监测终端也有极广的应用市场。为了实现对固话话务明细的实时获取和电子管理,设计以STM32为核心的监测终端。该终端通过外围电路获取FSK/DTMF制式来显信息,检测摘挂机状态以及按键组合,并通过网络模块与服务器实现通信。实际应用中,该终端有较高的稳定性、准确性和实时性,并且已成功应用到挂机短信系统中。Since the fixed-line telephone is widely used, the monitoring terminal managing the fixed-line telephone traffic information also has a wide application market. In order to realize the real-time acquirement and e-management of the fixed-line telephone traffic information details, a monitoring terminal was designed, which takes STM32 as the core. This terminal ac- quires the ID caller information in FSK/DTMF modes and detects the status of on/off hook and keystroke combination by means of peripheral circuit, and communicates with the PC server via network module. In practical applications, this terminal has high stability, accuracy and real-time performance, and is applied to the on-hook short message system successfully.
