In the water treatment field, about 40,000 wastewater treatment plants are currently installed and operated in Korea, and since the wastewater purified from environmental facilities is so diverse in nature and the amount of generation is not constant, facilities are installed to meet the environmental standards. As it is not easy to operate, the reality is that the field managers are resident in the workplaces using automated environmental facilities.

 Environmental facilities have difficulties in managing the resident in the relevant environmental facilities because the treatment operation of the facilities differs according to the characteristics and the amount of pollutants to be treated and the process configuration is complicated as described above.

Therefore, the cost burden is not small, and when the environmental equipment is located on the outskirts of the province, highway side, there is a problem that the arrangement of professional managers is difficult.

Therefore, a professional manager can remotely manage a large number of environmental facilities 24 hours at a remote location, and when a problem occurs, a management system for monitoring / controlling the operation of the corresponding environmental equipment is required.

In addition, DC power generated from eco-friendly renewable energy such as photovoltaic power generation, fuel cell, and secondary battery is stored in the battery and converted into alternating current when used as driving power for various electronic devices (automatic control panel). After switching to AC and converting to DC again, the electronic device is driven.

When the conversion efficiency is 90%, the efficiency of the new and renewable energy actually used during the three stages of storage discharge, alternating current, and direct current conversion of the battery drops to 72%.

In other words, the main task is to secure the stability of the switchgear and the remote control to increase the efficiency of driving the electronic device with the generated power source, not to increase the power generation efficiency of the solar cell.

In addition, the remote monitoring control is to use a wired network (Internet network, intranet) is basically the wireless control has the problem of error, the Internet network which is the most stable and stable wired network network is the most used.

However, in the above case, when a failure such as a server occurs in the main service provider providing the Internet service, there is a problem in that remote communication control is impossible due to the interruption of Internet communication.

In addition, although it uses a single IP, it is separated into a virtual internal network and a virtual external network by using two mainboards, thereby securing security.

Renewable energy such as wind, solar, and solar heat seeks stable power supply by storing DC power generated in the storage battery due to irregularities in power generation and generation time.

However, energy conversion loss occurs according to the stable power supply as described above. In order to solve this problem, the number of times of energy conversion is minimized.

In addition, the conversion loss is minimized by simplifying the method of supplying power to an electronic device (automatic control panel) by converting the direct current from direct current to alternating current.

In the current remote control, there is no countermeasure in the event of a failure of a wired network, thus solving a problem that is difficult to cope with a failure in a wired network.

In particular, the present invention is a technology that strengthens the security system, the integrated control server for automatic control of the plant equipment and the remote control server connected to the public network (wired or wireless Internet network) is connected to the network network after going through the firewall IP In case of web page IP provided by company classified as internal network by separating IP of web page connected by filter, it is classified as virtual internal network and uploaded to the first main board.

If the web page IP other than the above is classified as a virtual external network, it is uploaded to the second main board.

Conversely, when booting the remote control server for the first time, the system to be booted has two main boards booted or selectively booted at the same time. When the IP of the web page accessed by the user through the integrated control unit is classified as an internal network, the first system is the first. The web page is connected to the web page through the main board, and the web page is connected to the web page through the second main board in the case of an IP other than the above.

In addition, this technology is a system in which the virtual internal network and the virtual external network are secured by physical independence so that two main boards are operated independently, and the data of the second main board can be transmitted to the first main board. However, data of the first mainboard is not transmitted to the second mainboard.

That is, the web page (virtual intranet network) operation of IP related to remote control is performed solely through the first main board and the first memory, and the web surfing operation is connected to the public network (internet network). The information and data obtained through the main board and the second memory can be transmitted only in one direction.

The internal network connected to the private line and the internet network do not exist in duplicate, but the IP of the webpage connected from the IP filter is separated and the virtual internal network and the internet network are separated and processed independently from the main board to secure the data. It is possible to transmit in one direction.

In conclusion, the public network (Internet network) can be accessed only through the second main board and can transmit data to the virtual corporate network (virtual intranet network). It is impossible to import or access data, so even if there is a hacker's intrusion from the outside, it is impossible to connect to or import data from the virtual company network, so it has both security and convenience.

In addition to the function of the general switchgear, which converts the special high voltage supplied by KEPCO into a low-voltage commercial power supply, the DC power generated from renewable energy is effectively used (high efficiency) to improve the overall energy efficiency. Minimize obstacles to remote control even in the event of an internet network failure.

In addition, it is a system with enhanced security that uses a public network but is separated into a virtual internal network and an external network.
