Can be.

In this case, the protocol converter 300 converts the communication data including the site association monitoring and control information from the first serial communication protocol to the short range wireless communication protocol or from the short range wireless communication protocol to the first serial communication protocol. Perform the function of converting.

The server 500 is connected to the main device 100 located in each distribution panel 10 through Ethernet, and the server 500 receives the distribution panel measurement information generated in each distribution panel 10 and the corresponding distribution panel 10. Receive site-related monitoring and control information related to the site where) is located. Therefore, the server 500 may associate the distribution panel measurement information and the site association monitoring and control information regarding the same distribution panel 10 through the identification address of the distribution panel 10 or the main device 100, thereby easily quantifying the two. There is an effect that can be analyzed by associating.

Furthermore, according to an embodiment of the present invention, since individual measurement information may be generated for each branch line to which a load is connected, the main unit 100 and the server 500 may obtain individual measurement information for each branch line. Therefore, when analyzing site-related monitoring and control information, it is possible to utilize individual measurement information for each load and branch line. In addition, there is an effect that it becomes very easy to analyze the individual measurement information by load and branch line in association with the site association monitoring and control information.

According to an aspect of the present invention, there is an effect that can easily cope with various short-range wireless communication standards in configuring an integrated monitoring and control system. According to an aspect of the present invention, there is no need for a separate product design for converting between various short range wireless communication protocols and a private protocol, and there is no need for a separate product design even when the short range wireless communication protocol is upgraded.

According to an aspect of the present invention, not only the distribution panel measurement information but also the site association monitoring and control information for the sensor 51 and the controller 52 may be automatically classified using the same identification address. According to an aspect of the present invention, the site association monitoring and control information may have a specific identification address, for example, a specific IP address, etc., through which it is possible to identify what is associated with a specific distribution panel 10, and further, the association monitoring described above. There is an effect of being able to automatically identify that the control information relates to the site covered by the particular distribution panel 10.
