The present invention provides a circuit and method for detecting the reliability of the power supply of copper bars for a server in a complete cabinet. The present invention detects the contact voltage drop before and after the contact point of the node server by adding the detecting circuit, calculates the actual resistance value of the contact resistance, and compares it with the actual resistance value of the contact resistance. The standard organization conducts comparison, and evaluates the contact state according to the comparison result, so as to realize real-time monitoring of the contact state between the node power connector and the copper bar. Compared with the traditional control method, the invention can quickly locate the problem and save the time for troubleshooting; the identification accuracy is high, and by monitoring the contact voltage drop, it is not disturbed by the fluctuation of the power supply voltage of the copper bar; the monitoring work is performed in real time, which can effectively identify Instantaneous and continuous poor contact of the connectors can effectively eliminate the potential hidden dangers of the entire cabinet server and ensure the stable operation of the server; real-time recording of abnormal contact alarms, timely sending of alarm signals, to prevent the server from working in an abnormal state, and to provide maintenance personnel with maintenance. in accordance with.
