User operation state detection method and device of high-speed industrial communication system

The invention relates to a user operation state detection method of a high-speed industrial communication system. According to the user state detection method and device for the high-speed industrial communication system disclosed by the invention, the state of the user node can be quickly and effectively obtained by checking the message sent by the user node and counting the checking error, so that effective countermeasures can be timely started when the user node has a fault or is offline. The high-speed industrial communication system is mainly used for solving the problems that a traditional bus in an industrial field is low in bandwidth, cannot bear real-time and non-real-time at the same time and is complex in network structure, and can support IPV6 address communication, time-triggered industrial control communication, TSN, and security mechanisms such as white list, deep detection and data encryption can be supported. 本发明涉及一种高速工业通信系统的用户运行状态检测方法。根据本发明公开的高速工业通信系统的用户状态检测方法和装置，通过对用户节点发送消息进行校验和统计校验错误，能够快速有
