具体实施方式Detailed ways

下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

如图1至3所示，根据本发明的实施例，通话录音系统包括主录音系统、备录音系统和监测系统。主录音系统用于对通话进行录音；备录音系统用于在主录音系统无法正常录音时对通话进行录音；监测系统用于监测主录音系统的工作状态，并根据主录音系统的工作状态控制备录音系统的工作状态。As shown in Figures 1 to 3, according to the embodiment of the present invention, the call recording system includes a main recording system, a backup recording system and a monitoring system. The main recording system is used to record calls; the backup recording system is used to record calls when the main recording system fails to record normally; the monitoring system is used to monitor the working status of the main recording system and control the backup The working status of the recording system.

在对通话设备的通话进行录音时，如果声音信号质量好，则可以通过主录音系统进行录音，使得录音效率较高，信息传递速度较快，能够较快处理故障；当声音信号质量不好时，则可以通过备录音系统进行录音，从而提高录音质量，保证录音信息完全，保证录音信息传递的完整性。When recording the call of the communication device, if the sound signal quality is good, it can be recorded through the main recording system, so that the recording efficiency is higher, the information transmission speed is faster, and the fault can be handled faster; when the sound signal quality is not good , you can record through the standby recording system, thereby improving the recording quality, ensuring the integrity of the recording information, and ensuring the integrity of the recording information transmission.

将主录音系统和备录音系统结合在同一通话设备内使用，就可以在信号质量好的情况下优先保证信息的传递速度，使得故障情况能够尽快被了解，并及时作出处理。在信号质量差的情况下就可以优先保证信息的完整性和准确性，从而为后续处理提供真实可靠的信息，使得后续的处理更加具有针对性。Combining the main recording system and the backup recording system in the same communication device can give priority to ensuring the transmission speed of information when the signal quality is good, so that the fault situation can be understood as soon as possible and dealt with in time. In the case of poor signal quality, the integrity and accuracy of information can be guaranteed first, so as to provide true and reliable information for subsequent processing, making subsequent processing more targeted.

主录音系统和备录音系统均包括静态录音模块和语音激励式的动态录音模块，操作人员可以根据需要选用静态录音模块或动态录音模块进行录音。Both the main recording system and the backup recording system include a static recording module and a voice-activated dynamic recording module, and the operator can choose a static recording module or a dynamic recording module for recording according to needs.

动态录音模块包括语音识别模块和静音时间模块，语音识别模块用于确定是否有声音出现；静音时间模块用于比较动态录音模块录音过程中的静音时间与设定静音时长。其中，在语音识别模块确定有声音出现的情况下，动态录音模块录音，并根据静音时间模块的比较结果确定是否停止录音。The dynamic recording module includes a speech recognition module and a silent time module. The speech recognition module is used to determine whether there is sound; the silent time module is used to compare the silent time during the recording process of the dynamic recording module with the set silent duration. Wherein, when the voice recognition module determines that there is a sound, the dynamic recording module records, and determines whether to stop recording according to the comparison result of the silent time module.

主录音系统与通话设备之间通过逻辑链接方式链接，从而保证信息录制和传递的快速性，备录音系统与通话设备之间通过物理链接方式链接，从而保证信息录制和传递的完整性。在本实施例中，主录音系统通过网络访问系统对通话设备进行录音，例如WinCap技术，备录音系统采用传统的并线方式通过数字中继线对通话设备进行录音。主录音系统采用WinCap技术，通过硬件设备网卡抓包的方式进行录音，该种录音方式可靠性高，成本低，性能强、可扩展性好，能够在设备与设备之间IP层面实现语音激励方式和静态方式两种录音方式。The main recording system and the communication equipment are linked through a logical link to ensure the rapidity of information recording and transmission, and the backup recording system and the communication equipment are linked through a physical link to ensure the integrity of information recording and transmission. In this embodiment, the main recording system records the call device through a network access system, such as WinCap technology, and the standby recording system uses a traditional parallel method to record the call device through a digital trunk. The main recording system adopts WinCap technology, and records through the network card of the hardware device. This recording method has high reliability, low cost, strong performance, and good scalability. It can realize voice excitation at the IP level between devices. There are two recording modes: static mode and static mode.

根据本发明的实施例，录音方法包括：启动录音系统对通话进行录音；监测主录音系统是否正常工作，当主录音系统处于非正常工作状态，启动备录音系统对通话进行录音，当主录音系统正常工作时，则关闭备录音系统。启动录音系统对通话进行录音时，需要首先确定声音信号质量是否满足主录音系统录音要求，如是，则启动主录音系统录音，如否，则启动备录音系统录音。According to an embodiment of the present invention, the recording method includes: starting the recording system to record the call; monitoring whether the main recording system is working normally, when the main recording system is in an abnormal working state, starting the backup recording system to record the call, and when the main recording system is working normally , turn off the standby recording system. When starting the recording system to record a call, it is first necessary to determine whether the quality of the sound signal meets the recording requirements of the main recording system. If so, start the recording of the main recording system; if not, start the recording of the backup recording system.

在启动录音系统对通话进行录音之前，还需要首先根据系统中的设置判断通过动态录音模块进行动态录音还是通过静态录音模块进行静态录音。当采用动态录音模块进行动态录音时，首先启动动态录音模块，然后监测通话设备中是否存在声音，如是，则开始录音；在录音过程中，通过静音时长模块内设定的静音时长与录音过程中的时间进行比较，当静音时间大于设定静音时长时，则关闭通信链路，停止录音，如果静音时间小于设定静音时长，则继续录音。当静音时间大于设定静音时长时，可以通过设定的静音时长对通话设备进行周期性声音监测。在采用设定静音时长对通话设备进行周期性声音监测期间，若在第n周期发现有声音出现，则主录音系统恢复第n-1周期数据，录音从第n周期开始。动态录音模块采用语音激励的方式进行录音，可根据人员的讲话录音，自动截取没有声音的空信息，打破传统的静态录音机制，从而为事故分析提供重要的声音资料，减少了编辑录音的时间。Before starting the recording system to record the call, it is necessary to judge whether the dynamic recording is performed through the dynamic recording module or the static recording is performed through the static recording module according to the settings in the system. When using the dynamic recording module for dynamic recording, first start the dynamic recording module, then monitor whether there is sound in the communication device, and if so, start recording; When the silence time is greater than the set silence time, the communication link will be closed and the recording will be stopped. If the silence time is less than the set silence time, the recording will continue. When the mute time is longer than the set mute time, periodic sound monitoring can be performed on the calling device through the set mute time. During the periodic sound monitoring of the calling device with the set silence duration, if a sound is found in the nth cycle, the main recording system will restore the data of the n-1th cycle, and the recording will start from the nth cycle. The dynamic recording module uses voice excitation to record, and can automatically intercept empty information without sound according to the personnel's speech recording, breaking the traditional static recording mechanism, thereby providing important sound information for accident analysis and reducing the time for editing recordings.

当系统选择采用静态录音模块进行静态录音时，则在通信链路打开的第一时间就可以通过静态录音模块对通话设备进行录音。静态录音设备不做静音判别，录音文件中包含静音。When the system chooses to use the static recording module for static recording, the call device can be recorded through the static recording module as soon as the communication link is opened. The static recording device does not judge silence, and the recording file contains silence.

在进行录音工作时，主录音系统采用网络访问系统对通话设备进行录音，备录音系统通过传统的并线方式采用数字中继线对通话设备进行录音。When performing recording work, the main recording system uses the network access system to record the call equipment, and the backup recording system uses the digital trunk line to record the call equipment through the traditional parallel method.

在完成录音之后，可以通过处理系统读取语音包，并对语音包进行混音处理，最后将混音后的录音文件写入语音文件进行传输或者播放。After the recording is completed, the voice packet can be read through the processing system, and the voice packet can be mixed, and finally the mixed recording file can be written into a voice file for transmission or playback.

下面以800M手持对讲系统为例对本发明的通话录音系统的工作过程加以说明。The following takes the 800M handheld intercom system as an example to illustrate the working process of the call recording system of the present invention.

800M录音系统由主录音系统和备录音系统组成，其中主录音系统采用WinCap技术对800M手持对讲系统进行录音，备录音系统采用传统并线方式通过数字中继线对800M手持对讲系统进行录音。The 800M recording system is composed of the main recording system and the backup recording system. The main recording system uses WinCap technology to record the 800M handheld intercom system, and the backup recording system uses the traditional parallel method to record the 800M handheld intercom system through digital trunk lines.

800M录音系统通过800M网关与800M手持对讲系统相连接。800M录音系统通过网关实时监测800M手持对讲系统中的信号状态，若信号状态处于良好或正常状态下时，录音系统自动监测主录音系统运行状态，判断主录音系统出否处于正常运行状态，若主录音系统处于正常运行状态，系统自动设置主录音系统为默认录音系统；若主录音系统处于非正常运行状态，系统自动设置备录音系统为默认录音系统。若信号状态处于差时，系统自动设置备录音系统为默认录音系统，采取并线方式通过数字中继线对800M手持对讲系统进行录音。通过上述方式可以确保无论800M手持对讲系统处于何种状态都可以对其进行录音操作。The 800M recording system is connected to the 800M handheld intercom system through the 800M gateway. The 800M recording system monitors the signal status of the 800M handheld intercom system in real time through the gateway. If the signal status is good or normal, the recording system automatically monitors the operating status of the main recording system to determine whether the main recording system is in normal operation. If the main recording system is in normal operation, the system will automatically set the main recording system as the default recording system; if the main recording system is not in normal operation, the system will automatically set the backup recording system as the default recording system. If the signal status is poor, the system automatically sets the backup recording system as the default recording system, and adopts parallel mode to record the 800M handheld intercom system through the digital trunk line. Through the above method, it can be ensured that no matter what state the 800M handheld intercom system is in, it can be recorded.

800M录音系统采用主录音系统后，根据录音系统中的设置判断采用录音机制采用动态录音（语音激励）还是静态录音方式对800M手持对讲系统进行录音。After the 800M recording system adopts the main recording system, according to the settings in the recording system, it is judged whether the recording mechanism adopts dynamic recording (voice excitation) or static recording to record the 800M handheld intercom system.

系统采用动态录音机制开始录音时，主录音系统通过动态录音模块与800M网关进行通信协商、建立通信通道并打开双方通信链路。例如，动态录音模块通过INVITE向800M网关发出进行通信协商信号，800M网关接收到信号之后，发出200OK信号表示收到请求信号并同意建议通信通道，然后动态录音模块发出ACK信号表示接到建立信号，并与800M网关之间建立通信通道，打开通信链路。动态录音机制在通信链路打开的同时第一时间监测800M手持对讲系统中是否存在声音。若有声音出现，系统开始录音，在录音同时主录音系统根据系统中设定的静音时间，监测通信链路中的声音是否满足所设定的静音时间，若满足静音时间要求，系统则关闭通信链路，停止录音。若不满足静音时间要求，系统则继续录音，直至满足静音时间要求为止停止录音。若通信链路中没有声音出现，主录音系统则根据系统中设定的静音监测时长为周期，进行周期性声音监测。在周期性声音监测期间，若在n周期发现有声音出现，系统将自动恢复n-1周期数据，录音n-1周期开始。在动态录音模块录音结束时，向800M网关发出BYE信号，标明录音结束，800M网关结束通信通道，并回复200OK至动态录音模块，完成录音。When the system uses the dynamic recording mechanism to start recording, the main recording system communicates and negotiates with the 800M gateway through the dynamic recording module, establishes a communication channel and opens the communication link between the two parties. For example, the dynamic recording module sends a communication negotiation signal to the 800M gateway through INVITE. After receiving the signal, the 800M gateway sends a 200OK signal to indicate that it has received the request signal and agrees to suggest a communication channel. Then the dynamic recording module sends an ACK signal to indicate that it has received the establishment signal. And establish a communication channel with the 800M gateway to open the communication link. The dynamic recording mechanism monitors whether there is sound in the 800M handheld intercom system at the same time when the communication link is opened. If there is a sound, the system starts to record. At the same time, the main recording system monitors whether the sound in the communication link meets the set silence time according to the silence time set in the system. If it meets the silence time requirement, the system closes the communication Link, stop recording. If the silent time requirement is not met, the system will continue to record until the silent time requirement is met and stop recording. If there is no sound in the communication link, the main recording system will perform periodic sound monitoring according to the period of silence monitoring set in the system. During periodical sound monitoring, if a sound is found in period n, the system will automatically recover the data of period n-1, and the recording period n-1 will start. When the recording of the dynamic recording module ends, a BYE signal is sent to the 800M gateway to indicate the end of the recording, and the 800M gateway ends the communication channel, and replies 200OK to the dynamic recording module to complete the recording.

若系统采用静态录音机制开始录音，主录音系统通过静态录音模块与800M网关进行通信协商、建立通信通道并打开双方通信链路，静态录音机制在通信链路打开的第一时间对800M手持对讲系统进行录音。静态录音机制不做静音判别，录音文件中包含静音。静态录音模块的录音方式与动态录音模块的录音方式相同，此处不再详述。If the system uses the static recording mechanism to start recording, the main recording system communicates with the 800M gateway through the static recording module, establishes a communication channel, and opens the communication link between the two parties. The system records. The static recording mechanism does not judge silence, and the recording file contains silence. The recording method of the static recording module is the same as that of the dynamic recording module, and will not be described in detail here.

800M录音系统采用备录音系统后，根据录音系统中的设置判断采用录音机制采用动态录音（语音激励）还是静态录音方式对800M手持对讲系统进行录音。After the 800M recording system adopts the standby recording system, according to the settings in the recording system, it is judged whether the recording mechanism adopts dynamic recording (voice excitation) or static recording to record the 800M handheld intercom system.

当系统采用动态录音机制开始录音时，备录音系统与800M网关通过中继线建立通信链路。动态录音机制在通信链路打开的同时第一时间监测800M手持对讲系统中是否存在声音。若有声音出现，系统开始录音，在录音同时主录音系统根据系统中设定的静音时间，监测通信链路中的声音是否满足所设定的静音时间，若满足静音时间要求，系统则关闭通信链路，停止录音。若不满足静音时间要求，系统则继续录音，直至满足静音时间要求为止停止录音。若通信链路中没有声音出现，主录音系统则根据系统中设定的静音监测时长为周期，进行周期性声音监测。在周期性声音监测期间，若在n周期发现有声音出现，系统将自动恢复n-1周期数据，录音n-1周期开始。When the system uses the dynamic recording mechanism to start recording, the standby recording system establishes a communication link with the 800M gateway through the trunk line. The dynamic recording mechanism monitors whether there is sound in the 800M handheld intercom system at the same time when the communication link is opened. If there is a sound, the system starts to record. At the same time, the main recording system monitors whether the sound in the communication link meets the set silence time according to the silence time set in the system. If it meets the silence time requirement, the system closes the communication Link, stop recording. If the silent time requirement is not met, the system will continue to record until the silent time requirement is met and stop recording. If there is no sound in the communication link, the main recording system will perform periodic sound monitoring according to the period of silence monitoring set in the system. During periodical sound monitoring, if a sound is found in period n, the system will automatically recover the data of period n-1, and the recording period n-1 will start.

当系统采用静态录音机制开始录音时，备录音系统与800M网关通过中继线建立通信链路，静态录音机制在通信链路打开的第一时间对800M手持对讲系统进行录音。When the system uses the static recording mechanism to start recording, the standby recording system and the 800M gateway establish a communication link through the trunk line, and the static recording mechanism records the 800M handheld intercom system as soon as the communication link is opened.
