Method and device for detecting connection state of universal port of Sacker bus

The invention discloses a universal port connection state detection method and device for a Sacker bus. The method comprises the following steps: establishing communication connection between a to-be-detected first port and a to-be-detected second port; when the first port continuously sends the port detection packets to the second port for multiple times, recording the number of times that the first port sends the port detection packets and the number of times that the first port receives response packets; and determining the port state of the first port based on the number of times of sending the port probe packet and the number of times of receiving the receiving response packet. According to the method, any bottom layer transmission interface state identification mode is not adopted to judge the port connection validity of the Sacker bus, so that the authenticity, accuracy and universality of the connection validity judgment are realized. 本申请公开了一种用于沙克总线的通用端口连接状态检测方法及装置，包括：建立待检测的第一端口与第二端口的通信连接；当第一端口连续多次发送端
