步骤(1)获取语音指令集，所述语音指令集中包括操作指令和电网模型名称；Step (1) obtains a voice instruction set, the voice instruction set includes an operation instruction and a power grid model name;
在本发明实施例的一种具体实施方式中，所述语音指令集是一串字符串形式的正则表达式，用于配合实现将满足指定规则的字符串转化成电力系统对应的操作指令，具体地，所述语音指令集的获取过程为：In a specific implementation of the embodiment of the present invention, the voice instruction set is a regular expression in the form of a string of strings, which is used to cooperate with the realization of converting a string that satisfies a specified rule into an operation instruction corresponding to the power system. Ground, the acquisition process of the voice command set is:
首先，归纳总结出可以使用语音操作的功能进程，如打开指定厂站接线图，调用数据库维护工具，查询今日告警等；First, summarize the functional processes that can be operated by voice, such as opening the wiring diagram of the designated plant, calling the database maintenance tool, querying today's alarms, etc.;
其次，对于功能进程中会以参数形式出现的模型名称，如厂站名称、间隔名称和设备名称进行提取，与进程结合形成与电力系统相对应的语音指令集，如“打开xxx厂站接线图”对应操作指令“GExplorer-pic xxx.g-push-context 1”；Secondly, extract the model names that will appear in the form of parameters in the function process, such as plant name, interval name and device name, and combine with the process to form a voice command set corresponding to the power system, such as "Open the xxx plant and station wiring diagram. "Corresponding to the operation command "GExplorer-pic xxx.g-push-context 1";
进一步地，为了提高识别的准确率，所述方法还包括：向所述语音指令集中增加新的操作指令和电网模型名称；Further, in order to improve the recognition accuracy, the method further includes: adding a new operation instruction and a power grid model name to the voice instruction set;
步骤(2)基于语音识别服务将获取到的音频流在线转换成字符串；Step (2) converts the obtained audio stream into character string online based on speech recognition service;
具体地，在本发明实施例的一种具体实施方式中，所述基于语音识别服务将获取到的音频流在线转换成字符串，具体包括以下步骤：Specifically, in a specific implementation of the embodiment of the present invention, the online conversion of the acquired audio stream into a string based on the speech recognition service specifically includes the following steps:
调用操作系统的声卡驱动，从麦克风端口获取音频流，并直接实时传送至语音识别服务(ATS)，无须压缩转换格式或保存音频文件；Call the sound card driver of the operating system, obtain the audio stream from the microphone port, and directly transmit it to the Speech Recognition Service (ATS) in real time without compressing and converting the format or saving the audio file;
所述语音识别服务在线即时将获得的音频流转换成字符串，实现高效的语音识别转译功能；The speech recognition service instantly converts the obtained audio stream into a string online to realize an efficient speech recognition and translation function;
进一步地，在本发明实施例的其他实施方式中，所述语音识别服务还自动判断音频流是否结束，若没结束则继续接收音频流；若结束了，则立即返回识别出来的字符串，具体实现过程为：Further, in other implementations of the embodiment of the present invention, the speech recognition service also automatically determines whether the audio stream ends, and if not, continues to receive the audio stream; if it ends, immediately returns the identified character string, specifically The implementation process is:
在获取音频流时，通过识别语句的停顿长短，判断语音指令是否已经传达完毕，自动结束获取音频流操作，并即时返回识别结果，提升使用者的操作体验；When acquiring the audio stream, by identifying the pause length of the sentence, it is judged whether the voice command has been conveyed, the operation of acquiring the audio stream is automatically ended, and the recognition result is returned immediately to improve the user's operating experience;
步骤(3)基于维护过的词句映射文件，对所述字符串进行二次转换，形成新的字符串；Step (3) is based on the maintained word and sentence mapping file, and secondary conversion is carried out to the character string to form a new character string;
由于语音识别服务本身算法与操作者语调、语气、发音之间存在差别，识别结果无法达到完全的准确；为此，需要对获得的字符串中，经常使用且识别有误的词句进行二次转换，再通过语音指令集转译为系统操作进程，即可提高识别指令的正确率。在本发明实施例的一种具体实施方式中，所述基于维护过的词句映射文件，对所述字符串进行二次转换，形成新的字符串，具体包括：Due to the differences between the speech recognition service algorithm and the operator's intonation, tone, and pronunciation, the recognition results cannot be completely accurate; for this reason, it is necessary to perform secondary conversion of frequently used and incorrectly recognized words and phrases in the obtained strings. , and then translated into the system operation process through the voice command set, the accuracy of the recognition command can be improved. In a specific implementation of the embodiment of the present invention, the second conversion is performed on the character string based on the maintained word and sentence mapping file to form a new character string, which specifically includes:
将所述语音识别服务中原有的词句映射关系中的识别有误的词句强制转换成正确的词句，形成维护过的词句映射关系；比如：通过建立词句映射关系，如“千伏＝kV”、“直行＝执行”等；Forcibly convert the wrongly identified words and sentences in the original word and sentence mapping relationship in the speech recognition service into correct words and sentences, and form a maintained word and sentence mapping relationship; for example: by establishing a word and sentence mapping relationship, such as "kV=kV", "Go straight = execute", etc.;
基于所述维护过的词句映射关系对由步骤(2)获得的字符串进行二次转换获得新的字符串；The character string obtained by step (2) is subjected to secondary conversion to obtain a new character string based on the maintained word and sentence mapping relationship;
步骤(4)基于获得的语音指令集对所述新的字符串进行自动识别，获得操作指令，完成电力系统操作指令执行；所述自动识别过程具体为：将新的字符串与语音指令集中的各个字符串进行比对，从而完成将字符串转换成操作指令的过程，这部分可以采用现有技术。Step (4) automatically recognizes the new character string based on the obtained voice command set, obtains an operation command, and completes the execution of the power system operation command; the automatic recognition process is specifically: combining the new character string with the voice command set in the voice command set. Each character string is compared, so as to complete the process of converting the character string into an operation instruction, and this part can adopt the prior art.
