Description

TECHNICAL FIELD [0001] The present invention relates to a streetlight control system and a method for maintaining two-

The present invention relates to a streetlight control system, and more particularly, to a method of maintaining a two-way communication of a streetlight control system.

Street light is installed along the road for the safety of street lighting and traffic. It is installed on the highway, the main road of the city area, the commercial district road, the residential district road, and various kinds of street light are used depending on the installation place.

The streetlight is installed in a relatively large area, and it is necessary to manage the lighting time, the lighting time and the abnormality of the lighting facilities in order to prevent waste of energy. A streetlight control system is a system for efficiently managing a streetlight remotely.

The streetlight control system constitutes a lighting facility and a network in a management area through a communication network.

The conventional streetlight control system constitutes a network by using a DDNS (Dynamic Domain Name System), a fixed IP, a VPN (Virtual Private Network), or an IP update method using SMS messages.

However, among the network configuration methods of the streetlight control system, the method of configuring the network using the DDNS may cause a security problem because the domain information is exposed. In the method using the static IP, it is difficult to secure a large number of IPs. Since the method of using the service is implemented in cooperation with the communication company, the additional cost is expensive, and the method using the SMS text service has a problem that the network status is unstable due to the arrival of the character delay, the loss, and the server connection failure.

Therefore, there is a need for a method capable of bidirectional communication of a streetlight control system without incurring additional costs.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a streetlight control system for protecting a domain information of a streetlight control system and a bidirectional communication maintaining method thereof.

It is another object of the present invention to provide a streetlight control system for stably configuring a network of a streetlight control system without additional equipment and a method for maintaining a two-way communication.

A bidirectional communication control method of a streetlight control system of the present invention comprises the steps of: a distribution control device providing its own unique identification (ID) and an IP (Internet Protocol) of a router to a control server; The control server tableing and storing the unique ID of the distribution control device and the IP of the router; And searching the IP of the router for maintaining bidirectional communication based on the unique identification ID stored in the control server, and maintaining bi-directional communication with the distribution control device corresponding to the retrieved IP.

In the present invention, when the rebooting event of the router occurs, the distribution control device provides its own unique identification ID and the IP of the updated router to the control server. And the control server tables and stores the unique identification ID of the distribution control device and the IP of the updated router.

In the present invention, the distribution control device periodically reboots the router and sets the IP of the router to change so as to prevent the risk of an external attack that may occur by holding the fixed IP for a long time.

In the present invention, at the time of providing the status information corresponding to at least one of the schedule and the request of the control server, the status of the status information connected with the status, the unique identification ID of the status, And providing the IP to the control server.

In the present invention, the power distribution controller performs periodic status reporting to prevent loss due to IP change of the router.

In the present invention, the distribution control device and the router are connected to a local network and are set to maintain tunneling with at least one of a demultiplexer (DMZ) and a port forwarding scheme.

The streetlight control system of the present invention includes a distribution control device having a unique identification ID and managing state information of a street, a router having a pre-assigned IP address and relaying communications between the distribution control device and the outside, A distribution box for providing the unique identification ID of the router and the IP of the router to the control server; And a control server that keeps communication with the distribution box and stores the unique ID of the distribution control device and the IP of the router in a table and stores the IP of the router in a table based on the unique ID, .

In the present invention, the distribution control device transmits status information of the status, its own unique identification ID, and the current IP address of the router in association with at least one of a preset schedule and a request of the control server, .

As described above, according to the present invention, since the control server performs communication based on the unique identification ID of the distribution control device and the IP can be changed or updated when the status information of the lighting facility is provided, Can be safely protected.

In addition, since the present invention periodically reboots the router by rebooting the router, it is possible to lower the probability of an external attack that may occur due to a long IP hold.

Further, the present invention can maintain the bidirectional communication of the streetlight control system without the configuration of the additional system, thereby reducing the management and maintenance costs.
