That is, the present invention has the effect of distributing a function for processing a web document in the WEB server, thereby reducing the burden on the server. Particularly, this effect can be more remarkable in that the burden on the server for receiving data from a plurality of objects, for example, a plurality of communication companies, can be reduced.

Next, the system stores recording information (4) having an individual DB (database) for each group of individual objects (a set of individual objects linked to the LTE modem 12) And the like.

It has been described that the above-mentioned system can include the recording means 4. The present invention is further characterized in that the recording means 4 is provided with a separate DB (database) for each group of individual objects.

As described above, since the recording means 4 for storing the information on the measurement information and the consumption power amount are constituted by individual DBs for each group of the individual objects, it is possible to prevent overloading of the DB processing and to store the data quickly And load.

In particular, when the system 4 is introduced to the power measurement and analysis consumed by the base station of the mobile communication company, the recording means 4 can record in the individual DB for each mobile communication company. In FIG. 2, (Including measurement information and information on the amount of power consumed) of the first mobile communication company is recorded in the first DB 40A, and the second DB 40B is recorded with the second It is possible to record the meter reading information of the mobile communication company and to record the meter reading information of the third mobile communication company in the third DB 40C. FIG. 2 shows an example in which three individual DBs are included. However, the number of individual DBs can be increased if the number of mobile communication companies (the number of groups) is increased.

Next, the present system is characterized in that the integrated computing server 3 may further include a receiving unit 33 for receiving measurement information from the communication means 2. [

As shown in FIG. 2, the receiving unit 33 includes a firewall 331 for selectively receiving the measurement information from the input information, and a receiving unit 33 for receiving the WEB server, WAS server, and individual DB And a L4 switch 332 for distributing metrology information transmitted to the first to third 3DBs 40A, 40B, and 40C.

With the above feature, the present invention can improve the security through the firewall 331 and provide the load distribution effect through the L4 switch 332. [
