Abstract

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.

Claims

1. A system for controlling and monitoring a plurality of refrigerated containers, comprising:

one or more connection plugs, each of which is connected to a plug-in port of a control panel of each of the plurality of refrigerated containers, and configured to receive information regarding a state of each of the plurality of refrigerated containers from the plug-in port and transmit a control signal of each of the plurality of the refrigerated containers to the plug-in port;

one or more connection socket boxes, each of which is connected to the one or more connection plugs through a connection cable, and configured to receive the information regarding the state of each of the plurality of refrigerated containers and transmit the control signal of the refrigerated container to each of the one or more connection plugs; and

a management server connected to the one or more connection socket boxes through a communication cable, the management server being configured to receive the information regarding the state of each of the plurality of refrigerated containers and monitor the received state information, and generate the control signal of each of the plurality of refrigerated containers for transmission to the one or more connection socket boxes,

wherein the connection plug comprises;

an information transmission module connected to the plug-in port and configured to receive the information regarding the state of each of the plurality of refrigerated containers and transmit the control signal of each of the plurality of the refrigerated containers to the plug-in port; and

a power transmission module connected to the plug-in port and configured to receive a current driving power of each of the plurality of the refrigerated containers,

wherein the connection cable comprises a communication line and a power line which are in parallel connected to the information transmission module and the power transmission module independently, and

wherein the connection socket box further comprises the wattmeter connected to the power line of the connection cable and configured to measure the amount of power consumed of the plurality of the refrigerated containers.

2. The system according to claim 1, wherein the connection cable comprises an RS232 communication line connected to the plug-in port, an RS485 communication line connected to the one or more connection socket boxes, and a connection box installed between the RS232 communication line and the RS485 communication line and configured to interconnect the RS232 communication line and the RS485 communication line, and

wherein the communication cable is implemented as an optical communication cable.

3. The system according to claim 1, wherein the connection socket box comprises:

a first information input and output module including one or more first connection ports to which the communication line of the connection cable is connected, the first information input and output module being configured to receive information regarding the state of the refrigerated container from each of the plurality of the refrigerated containers and transmit the control signal of the refrigerated container to each of the plurality of the refrigerated containers;

the wattmeter module including a plurality of wattmeters; and

a second information input and output module including a second connection port to which the communication cable is connected, the second information input and output module being configured to transmit the information regarding the state of the refrigerated containers to the management server and receive the control signal of the refrigerated container from the management server.
