技术领域technical field
本发明涉及电力技术领域，更具体地，涉及一种UART串口TTL电平通信双向物理监听系统及方法。The present invention relates to the field of electric power technology, and more specifically, relates to a UART serial port TTL level communication two-way physical monitoring system and method.
背景技术Background technique
电力用户用电信息采集系统为实现其自身功能，要求采集终端与控制模块、本地模块、远程通信模块等功能模块通过UART进行通信。当系统功能异常时需通过监听采集终端与各个功能模块的通信报文来排查故障，比如当终端登录主站失败时需监听终端与远程模块之间的报文交互，以确认问题。而对于用电信息采集终端通信报文的监听，传统的方法包括：In order to realize its own functions, the electricity consumption information collection system of power users requires the collection terminal to communicate with the control module, local module, remote communication module and other functional modules through UART. When the system function is abnormal, it is necessary to monitor and collect communication messages between the terminal and each functional module to troubleshoot. For example, when the terminal fails to log in to the master station, it is necessary to monitor the message interaction between the terminal and the remote module to confirm the problem. As for the monitoring of the communication messages of the electricity consumption information collection terminal, the traditional methods include:
1、扩展采集终端软件功能，在采集终端接收到报文数据时通过其它通道将报文打出。此方法需要扩展软件功能，且各终端厂家扩展软件功能的难易度不同、实现方式也不同，造成使用方法不统一；通过软件的方法监听数据报文的实时性和原始性无法保证，一定程度上不具备客观性；需占用其它通道，影响采集终端正常功能；1. Expand the software function of the acquisition terminal, and print the message through other channels when the acquisition terminal receives the message data. This method needs to expand software functions, and the difficulty of extending software functions of each terminal manufacturer is different, and the implementation methods are also different, resulting in inconsistent usage methods; the real-time and originality of monitoring data messages through software cannot be guaranteed. It is not objective; it needs to occupy other channels, which will affect the normal function of the collection terminal;
2、使用杜绑线USB转TTL，测试过程需焊接线缆，对模块造成硬件损伤、操作不便；只能监听单一方向的数据如接收或者发送，如需监听双向通信，则需两套设备两套软件，即便如此也存在监听到的双向数据报文不同步，查看收发过程不便等问题。2. Use the Duty wire USB to TTL, the test process needs to weld the cable, which will cause hardware damage to the module and inconvenient operation; it can only monitor data in one direction, such as receiving or sending, if you need to monitor two-way communication, you need two sets of equipment. Even so, there are problems such as the monitored two-way data packets are not synchronized, and it is inconvenient to check the sending and receiving process.
同时，在对数据进行查看时，目前绝大多数用电信息采集终端使用的软件平台不支持在线调试，即便是支持在线调试，使用调试程序的方法监听报文数据也存在响应不及时，查看不方便，非产品开发人员无法查看等问题。At the same time, when viewing data, most of the software platforms currently used by electricity consumption information collection terminals do not support online debugging. Convenience, problems such as non-product developers cannot view.
