Description

Intelligent streetlight communication control system and its method {COMMUNICATING CONTROL SYSTEM FOR STREETLIGHT AND METHOD OF THE SAME}

The present invention relates to an intelligent street light communication control system and a method thereof, and more particularly, it is easy to install by using a wireless communication method, and can be installed at a low cost and enlarged, while being omnidirectional without specifying a transmission path in advance. The present invention relates to an intelligent street light communication control system and a method for transmitting radio communication data through various transmission paths without intermittent transmission.

As is well known, due to the recent development of information communication technology, development of information providing technology for providing information on various fields via a long distance data communication network to a plurality of subscribers through at least one host server is actively underway.

Based on this, recently, information and communication technologies have been connected to various fields, and street light control systems for remotely controlling distributed street lights have been proposed. In general, a street light control system includes a model for controlling only distribution boxes, It is composed of a model that controls both distribution boxes and street lamps, but recently, a control system for controlling both distribution boxes and street lamps is popular.

On the other hand, the conventional street light control system is largely divided into a wired method and a wireless method, it will be described in detail with reference to the drawings.

1 is a schematic diagram showing a conventional wired communication streetlight control system.

Referring to this, in the wired streetlight control system according to the related art, as shown in FIG. 1, a plurality of column controllers 100a to 100n and 200a to 200n respectively controlling a plurality of street lights 10 may communicate with each other by a cable. Each distribution box unit 20a to 20n, 30a to 30n is configured for each columnar control column 100 and 200 in a predetermined unit, and each distribution box unit 20a to 20n and 30a to 30n are formed in a predetermined unit. The cable is connected to a plurality of the column controllers 100a to 100n and 200a to 200n included in the column control columns 100 and 200 so as to enable wired communication.

In addition, by being installed in a central control center at a remote location, each distribution box unit (20a to 20n, 30a to 30n) distributed in multiple regions are connected to each other by a wired cable to communicate with each other distribution box unit 20a ~ A monitoring server 300 is configured to transmit control signals to 20n, 30a to 30n, or to receive and monitor status information of street lamps from the respective distribution box units 20a to 20n and 30a to 30n.

This configuration drastically changes the conventional streetlight system, which can only be determined by dispatching personnel to check which streetlight owner is out of order and whether the streetlight is turned on, and controls the lighting of the streetlight directly from a remote site and transmits the status information. It was possible to receive the dispatcher's dispatch frequency, and to check the status of each streetlight accurately.

However, a communication method using a wired communication cable has a problem in that a communication distance is short due to disconnection and obsolescence of a wired cable and a failure occurs frequently, thereby increasing maintenance costs. In addition, most of the lines are obsolete and the communication distance is limited to within 100m, so communication is impossible.Therefore, due to the failure to be notified in a timely manner, the monitoring information including the abnormality of the line is not timely. There was a problem.

In particular, in the communication method using the wired internet network, it is difficult to secure the wired internet line in order to use the internet network, and to access the central control server connected to the internet network, a fixed IP address must be assigned to each distribution box controller. There was a problem that the use cost is further increased.

Therefore, recently, a streetlight control system using a wireless communication method as shown in FIG. 2 has been developed.

Referring to this, in the conventional wireless communication street light control system as shown in Figure 2, a plurality of column controllers 400a to 400n, 500a to 500n to control a plurality of street lights 10, respectively, such as Zigbee wireless communication The distribution box portions 50a to 50n and 60a to 60n are configured for each column control column 400 and 500 in a predetermined unit, and the distribution boxes 50a to 50n and 60a to 60n are fixed to each other. A plurality of column controllers 400a to 400n and 500a to 500n included in the column control columns 400 and 500 of the unit and a wireless communication such as Zigbee can be configured.

In addition, by being installed in a central control center at a remote location, each distribution box unit (50a to 50n, 60a to 60n) distributed in multiple regions are connected to each other by a wired cable to communicate with each other distribution box unit (50a ~) The monitoring server 300 is configured to transmit control signals to 50n, 60a to 60n, or to receive and monitor status information of each streetlight from the distribution boxes 50a to 50n and 60a to 60n.

That is, as described above in the conventional street lamp control system using wireless communication, a hybrid method using a wireless and a wired has been adopted.

In the case of such a communication method, the installation is simple, the installation cost is low, and the expansion is easy. On the other hand, since the communication paths between the column controllers 400a to 400n and 500a to 500n are specified in advance, If a facility or a banner is provided to shield the wireless communication, there is a problem in that a communication error occurs because wireless communication with another neighboring controller is not made.

That is, since the transmission path is set in advance so that the data generated from the first column controller 400a is transmitted to the second column controller 400b, between the first column controller 400a and the second column controller 400b. If the communication block 40 is installed, there is a serious problem that the wireless communication data is blocked in the course of being transmitted on the transmission path and thus cannot receive the communication data from the distribution box that manages it.

The present invention has been made to solve the above-mentioned problems of the prior art, by using a wireless communication method is easy to install, low cost installation and expansion, while allowing the radio communication in a non-directional direction without specifying the transmission path in advance In addition, even if some street lamps are shielded through various transmission paths or if the controller is broken, the transmission of communication data is not interrupted.

Since it should be possible to check, each distribution box unit 50 is operated so as to determine whether the breakdown controller 600a to 600n belonging to it.

Next, the distribution box unit 50 transmits the analysis data of the column controllers 600a to 600n including the received data to the monitoring server 300, and the monitoring server 300 includes the column controllers 600a to 600n and Monitor the distribution box unit 50 for shielding or failure.

9 is a flowchart illustrating a signal flow of a distribution box included in an intelligent street light communication control system according to an exemplary embodiment of the present invention.

First, the distribution box unit 50 included in the intelligent street light communication control system according to an embodiment of the present invention sorts data received from at least two column controllers 600a to 600n.

Then, a single packet having a superior inclusion relation among the sorted data is selected. That is, the distribution box unit 50 may receive data from at least two or more column controllers 600a to 600n that contain the same data and have different data amounts, and thus select a packet having a larger data amount.

In this state, the distribution box unit 50 extracts the moved route information from the selected packet. That is, the movement route information is data passing information, and is composed of unique codes of the trajectory controllers 600a to 600n passing through.

In addition, the distribution box unit 50 compares the received movement route with the previously stored normal movement route, and determines whether the movement route matches.

As a result of the determination, the distribution box unit 50 determines that there is a failure of the column controller of the missing code (unique number) when there is a part of the path missing, and there is no path missing, and the part of the column controller is insufficient. It is determined that 600a to 600n are partially shielded.

On the other hand, the intelligent streetlight communication control system and method according to an embodiment of the present invention is not limited to the above embodiments, but various modifications can be made without departing from the technical gist thereof.
