泛在电力物联网终端网络安全自感知探针设计

Implementation of Network Security Self-sensing Probe for UPIoT Terminal

根据国家电网公司的要求,运行在发电厂和变电站的泛在电力物联网终端需要实现网络安全自感知功能。考虑到早期设计实现的终端装置没有专用的网络接口实现该功能,采用了外挂网络安全代理模块的方法实现至网络安全管理装置的接入功能,网络安全自感知探针则在终端本体实现,并采用异步串口将探测事件发送给代理模块。遵循有关标准规范,完成规定的管理事件、状态事件和安全事件探测和生成规范的格式,按规定的代理协议发送给代理模块。项目设计完成之后,在实验室进行了自感知探测和通信传输实验,能自感知所要求的事件并发送给网络安全管理装置。

According to the requirements of State Grid Corporation of China,the network security self-sensing function need to be realized on ubiquitous power internet of things terminals running in power plants and substations.Considering the terminal device designed and implemented in the early stage has no special network interface to realize this function,the access function to the network security management unit is realized by means of the external network security agent module,and network security self-sensing probe is implemented in terminal,and the detection events are sent to agent module by asynchronous serial port.Follow relevant standards and specifications,the specified management events,status events and security events are detected and generated the designated format,and sent to agent module by the designated protocol.After the completion of the project design,the experiments of detection and communication transmission are carried out in the laboratory,the required events can be sensed and sent to the network security management unit.
