The invention relates to a monitoring system with control of a refrigeration container and a refrigeration container connection socket box. A connection cable is connected to the compatible plug-in port commonly formed in refrigeration containers. The connection socket box connecting connection cables is used to collect the state information of each refrigeration container transferred to a management server, so that a monitoring system applicable to all kinds of refrigeration container is provided, and can transfer a control signal for the refrigeration container through the compatible plug-in port, thus making it possible to remotely control the refrigeration container. Hence the system is simplified so as to reduce the cost and improve the stability of the system. The function of monitoring the state information and the function of measuring the power consumption of the refrigeration container are also provided so as to reasonably calculate the cost of the actual power consumption.
