Embodiment Construction

[0033] The system block diagram of the present invention is as figure 1 Shown:

[0034] The system consists of the following parts: signal conditioning, signal amplification, analog / digital converter, start signal judgment, dump control processor, dual-port RAM, flash memory, ARM7 processor, keyboard display and Ethernet.

[0035] According to the functions realized by the system, the system can be divided into the following functional modules: signal conditioning and conversion module, audio data compression module, signal conditioning and conversion module, voice signal start judgment module, audio data compression module, audio data dump module, graphics An interface display module and a system remote management module.

[0036] The signal conditioning and conversion module is responsible for converting the input telephone voice data into voice level data for compression by the subsequent audio data compression module. The module is composed of 12 identical circuits, incl...

Abstract

The invention relates to a sound and time recording system of an embedded multi-channel phone. The system provided by the invention is characterized in that a signal conditioning component is connected to a signal amplification component; an analogue-digital (A/D) converter is connected to a starting signal judgment component and a dump control processor, and the output of the starting signal judgment component is respectively connected with the dump control processor and an ARM7 processor; the output of the dump control processor is connected with a dual-port RAM (random-access memory), the output of the dual-port RAM is connected with the ARM7 processor, and the output of the ARM7 processor is respectively connected with an Ethernet, a keyboard display and a flash memory, the function of starting and stopping sound recording of multi-channel phone voice according to a sound control signal is automatically realized, the sound recording content is circularly stored in a non-volatile memory in the system one by one according to the starting time of a conversation, a graph and remote management interface is provided, and the rapid retrieval, replay, backup and deletion of the sound recording content is realized through a local keyboard and a remote network so as to store, retrieve and replay the multi-channel phone voice content, therefore, the defect that the traditional sound recording phone is limited in recording time and inconvenient for management is solved, and the degree of automation is improved.

Description

technical field [0001] The invention relates to a telephone recording system, in particular to an embedded multi-channel telephone recording system. Background technique [0002] With the rapid development of modern communication technology, telephone has become a part of people's life and work. In particular, the rise of call centers, telephone banking and other services has made telephone recordings an important original evidence for services such as service commitments and financial transactions. Therefore, the telephone recording system is widely used in urban emergency linkage systems, trading departments, security departments, etc., and is of great significance for avoiding business disputes and clarifying business responsibilities. [0003] Before the present invention, the telephone recording system mainly has two kinds of realization modes: telephone set with recording function and PC type telephone recording system. The telephone recording function refers to the ...
