The present invention relates to a remote control of a street lamp, and more particularly, to perform sequential lighting control and collective control using coordinates of a street lamp, a coordinate list of a next transmission path, and a transmission destination coordinate, but based on the memory learning for the obstacle. The present invention relates to a mesh networking method for remote street light control that can construct a large-scale network by constructing avoidance logic and minimizing the amount of communication packets, and an apparatus applied thereto.

Conventional streetlight control system can control the lighting and turning off of the streetlight selectively or at the same time at a desired time from a long distance, but the administrator can only control in one direction, there is a problem that can not determine the failure state of the streetlight system . The main control unit wirelessly transmits a control signal including the area code, receives it from the streetlight controller, compares whether the area code included in the control signal is identical to its area code, and analyzes consecutive control data in the same case. Configured to control the streetlight fixtures.

However, although the street lamp controller of the conventional one-way street lamp wireless control system can control the lighting and turning off the lamp remotely by wireless, this is the overall operation state and failure status of the lamp, ballast, flasher, etc. There is a problem that cannot be confirmed and monitored remotely.

In order to solve the above problems, Korean Patent No. 10-0813132 discloses a communication cost reduction street light monitoring control system and method using a Zigbee network.

The Zigbee network used here is characterized in that each streetlight supervisory controller forms an ad hoc network that can act as a Zigbee router to extend the communication distance beyond 1-hop. The controllers 500, 510, 520, and 530 may transmit and receive data with each other. In addition to the same configuration as each of the streetlight monitoring controllers 500, 510, 520, and 530, the gateway 600 equipped with an airwave communication module such as CDMA may store data of each streetlight monitoring controller 500, 510, 520, and 530. By receiving both the Zigbee network and transmits to the streetlight control server 300 using the public network 200, such as CDMA or mobile communication so that the user (400, 410) can be provided with the necessary information over the Internet. In addition, the command signal transmitted from the streetlight control server 300 is transmitted to the lamplight monitoring controller 900 of the corresponding streetlight through the streetlight monitoring controller (500, 510, 520, 530). However, as described above, street lamp control using CDMA communication collectively controls a plurality of street lamps connected to one distribution box, and thus, there is a problem that individual lamps cannot be controlled, and it is difficult to identify whether a street lamp is broken. have. This results in unnecessary waste of power since no substantial remote management of the streetlight is achieved. In addition, the conventional street light control has a problem that the communication maintenance cost increases because the CDMA communication resources must be utilized. In general, one branch box can control about 20 to 30 street lights, and considering the wide area, it is recognized that communication maintenance costs will be enormous.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

First, prior to describing the mesh networking method according to the present invention, the system of the present invention includes at least two street lights 213, as shown in Figure 2, the power to switch the power of the street light 213 A control module, a state monitoring module for monitoring a power state of a street light, and a communication module for instructing power control to the power control module based on a short range communication protocol and receiving event information according to the power state and transmitting the short distance to the communication module. The configured street light controller 211 is installed for each street light 213.

In addition, based on the fixed coordinates of the street light 213, including transmission street light coordinate information, next transmission street light coordinate list information, transmission destination coordinate information according to the installation position of each street light, passing through within the transmission and reception radius of the communication module Constructs minimum distance information for the node, and holds transmission node list information whose priority is determined for the communication order between the street lamps 213 based on the minimum distance information, and according to the priority by the transmission node list information. Perform the individual control mode of individually receiving the individual control and the event information, and after the inter-node communication is performed based on the transmission node list information, generate the transmission success list information returned therefrom, and transmit the success success list. Broad control which performs collective control of each streetlight 213 or interlocking control between streetlights 213 by A server 201 that performs a network mode, a gateway 203 that receives event information for the street light 213 and transmits lighting control information according to an individual control mode or a broadcast mode performed from the server 201; And a portable wireless terminal 207 for receiving control and event information of the street light 213 based on API communication with the gateway 203, and connected to the server 201 to control and event information of the street light 213. It includes a management terminal 205 for monitoring.

Although the server 201 and the gateway 203 are separated in a communication structure, they may be implemented in a functionally similar structure. That is, the individual control mode and the broadcast mode provided by the server 201 can be sufficiently implemented in the gateway 203.

Here, in the individual control mode, in order to transmit the event information generated in the street lamp to the server 201, a route in which a communication node is formed from the street lamp 213 to the gateway 203, and the individual street lamp in the server 201 And a route through which a communication node is formed from the gateway 203 to the street light 213 to transmit a signal for controlling.

That is, the street light 213 is event information on the street light, and converts event information such as power state, luminance state according to lighting of the lamp into coded information, and then transmits it to the gateway 203 and the server 201. Each street light 213 detects the event information itself and transmits the event information to the gateway 203 based on the transmission node list information. The communication module of the street light 213 holds transmission node list information. When the communication module communicates with any one of the adjacent communication modules according to the transmission node list information, and if the communication is successful, the ID information of the street light 213 is transmitted. Save it.

On the other hand, if communication with any one of the adjacent communication modules is not made according to the transmission node list information, the ID of the corresponding street light 213 is to set the lowest, that is, the priority of the transmission node list to the lowest. Then, the communication with the ID on the transmission node list having the second priority is resumed and the communication is repeated to succeed with any one communication module.

According to this procedure, any one communication module succeeds in communication with another communication module in close proximity, and transmits event information detected by one communication module to another communication module.

On the other hand, controlling the individual street light in the individual control mode is to transmit the control information from the gateway 203 to the street light 213, the communication node determined according to the transmission node list information held in the server 201 Control information is provided. As described above, the transmission node list information includes transmission street light coordinates located in a communication radius, coordinates for the next transmission street, etc., which are formed based on the coordinate information of each street light 213, and together with the transmission node list information. By transmitting the control information, individual control of the street lamp is possible.

The broadcast mode may perform broadcasting at the gateway 203 or broadcast at the street light 213. First, broadcasting from the gateway 203 to each street light 213 is used when resetting the lighting time of the same information, for example, all street lights (including security lights), to all the street lights 213. Here, the gateway 203 transmits control information to the plurality of street lights 213 based on the transmission success list. The transmission success list is a list returned after the street lights are controlled by the transmission node list information. This is a list of successful transmissions to the nodes that communicated with each other.

Accordingly, the gateway 203 reconstructs the transmission success list into a reverse list, and then determines the communication node of the street lamp 213 based on this. That is, after the communication between the gateway 203 is sequentially performed from the street lamp 213 through the individual control mode described above, when each communication module accumulates ID information that has been successfully communicated and transmitted to the gateway 203, the transmission success list is transmitted. Assume that When gateway broadcasting is performed, control information is transmitted by resetting to the reverse direction of the transmission success list.

That is, since the transmission success list is list information created in a successful communication state between each communication module, when the broadcasting is performed based on the transmission success list, control information can be transmitted with high speed and accuracy.

In addition, when broadcasting is performed in the street lamp 213, which is performed for the purpose of linkage between the street lamp and the street lamp, and is used when an immediate response by the interlocking of the street lamps 203 is required.

3 is a view showing the main configuration of the control device applied in the present invention. The control apparatus includes a short range wireless communication module and a lamp module for operating a lamp module for high efficiency and low power control for the lamp device, including a short range wireless communication module and a state monitoring module for the street light 213. Is built into the module.

As described above, a Zigbee module may be used as the short range wireless communication module, but Bluetooth, a short range RF module, and the like may be used as necessary. The lamp module includes a driving circuit and a heating circuit for a lamp lamp applied to the street lamp 213. The state monitoring module includes a circuit for detecting state information of the street light 213 and performs a change in power supplied to the street light 213, a change in current, and an illuminance amount. As the voltage and current supplied to the street lamp 213 are maintained at the initial setting value, it is determined whether the street lamp is abnormal based on a preset error range based on the setting value. The illuminance detection is also the same, and when the illuminance value measured by the illuminance sensor exceeds the reference value, it is determined as an abnormal state.

Next, the structure of the street lamp controller 211 according to the present invention will be described with reference to the accompanying drawings.

The street light controller 211 has a unique ID, performs wireless communication between adjacent street light controllers based on a Zigbee communication protocol, and generates a street light according to the transmission node list information provided from the server 201 or the gateway 203. Form a communication node, store and manage the latest success ID information on the street lamps that have successfully communicated therefrom, and collectively monitor or monitor the state of the street lamps and control lighting on the individual control mode based on the recent success ID information. The ZigBee communication module 300 performs the broadcast mode for the street lamp by individually performing the avoidance node when a communication error is generated or receiving reverse list information of the transmission success list based on the minimum distance algorithm, and the Power phase for the street lamp according to the state monitoring control command of the Zigbee communication module 300 According to the state monitoring module 310 for performing the monitoring and illuminance monitoring and provide the result to the Zigbee communication module 300, and the control lamp lamp lighting control command of the Zigbee communication module 300, the lamp of the street lamp It is composed of a lamp module 320 to control the light off or brightness.

The minimum distance algorithm for generating the avoided node according to the communication error may be provided in the server 201 or the gateway 203, but is mounted in the Zigbee communication module 300 to enable intelligent search for the avoided node. can do.

The Zigbee communication module 300 secures an internal flash memory, and is equipped with an algorithm for operating a Zigbee communication protocol, and controls the state monitoring module 310 and the lamp module 320 according to the state monitoring and lighting control commands. The control device 305 is equipped with an interface algorithm for operation management, the ZigBee communication unit 303 for performing ZigBee communication according to the instruction of the control device 305, and the data provided by the ZigBee communication unit 303 It consists of a Zigbee antenna 301 for radiating to or receiving data from the outside.

In addition, the state monitoring module 310 is a voltage sensor 311 for monitoring the change and magnitude of the voltage supplied to the street light 213, and a current sensor 313 for measuring the amount of current supplied to the street light (213). And an illuminance sensor 315 for measuring illuminance when the street light 213 is turned on.

The lamp module 320 is rated as the lamp heat dissipation circuit 323 for facilitating heat dissipation of the lamp 321 mounted with the street light 213 and the lamp 321 according to the lighting command of the control device 305. And a lamp driving circuit 325 for supplying power.

Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.

4 is a view for explaining a transmission node method in the present invention. First, each street light 213 has unique ID information (P1, P2, P3 ... Pn), and holds each coordinate information measured when the street light 213 is installed. Therefore, the distance information between each street light 213 is a recognized state. The transmission node list information includes ID information of a street lamp located within a radius in which communication is possible with respect to any one transmission node (O: Origin). Then, the distance to the destination coordinates is calculated based on the coordinate information corresponding to the ID information, and one of the streetlights 213 having the minimum distance to the destination is set as the highest priority.

As shown, the street light 213 located within the radius of the communication smoothly around the transmission node (O) is located P1, P2, P3, P4, and the distance from the street (D: Destination) having the transmission destination coordinates The minimum P2 node has the highest priority. As illustrated, P1 has a second priority and P3 has a third priority. The above priority is a priority for attempting communication. If communication with the ID of the corresponding rank is not possible due to a communication failure, the corresponding ID is reset to the lowest priority and communication with the ID having the second priority is performed. Try. In the present invention, such a prioritization algorithm will be referred to as a minimum distance algorithm.

Therefore, when the communication node is determined by the above-described transmission node list information, each node communicates between the street lamps 213 according to the communication node. However, if communication is not possible due to a communication failure in any one communication node, the communication module of the node attempts to communicate with any one communication module based on the priority set according to the minimum distance algorithm. The corresponding communication node notifies a higher node of a communication failure due to a communication failure.

In addition, the communication node communicates with any one communication module by repeating the above process, and the ID information having succeeded in the final communication is recognized by the communication node, and is reset to the highest priority.

As a result, the communication nodes of the respective streetlights 213 are set by the transmission node list information, but each communication node determines an arbitrary communication node based on the minimum distance algorithm according to the situation. This determination is set as the highest priority in the corresponding communication node, and the communication node which has successfully communicated is notified to the upper node. As such, the communication node information which has successfully communicated through the upper node is finally collected by the gateway 203, and the collected information is assumed to be a transmission success list.

Next, the operation of the present invention will be described as an example.

FIG. 5 illustrates an individual control mode proposed in the present invention and is a procedure of transmitting control information from the gateway 203 to the street light 213 based on the transmission node list information. First, the gateway 203 transmits transmission node list information generated based on the coordinates of each street light 213 to the street light P1. It is assumed that the street lamp P1 is also set as the first priority in the transmission node list information.

When the street light P1 receives the transmission node list information and the control information, the street light P1 notifies the gateway 203 that the transmission node list information and the control information have been received. Then, the street light (P1) transmits the relevant information to the second street light (P2), in order to transmit the transmission node list information and control information to the second node set in the transmission node list information, and confirms the transmission completion.

Subsequently, although the street lamp P2 is set as the third transmission node, the street lamp P3 is set, but when communication is not performed, the street lamp P2 selects a street lamp in proximity according to the minimum distance algorithm described above. If the street light P4 is selected, the street light P2 transmits transmission node list information and control information to the street light P4. Then, the reception completion state is recognized.

In this case, since the minimum distance algorithm is defined by the priority of the communicable object, the minimum distance algorithm is preferably reset according to the set priority without calculating a separate minimum distance algorithm. For example, when the first priority of the street light (P2) is a street light (P3), the second priority is the street light (P4), if communication with the street light (P3) is not made, the second priority Therefore, the communication with the street light (P4) is to try.

Through such a procedure, the transmission node list information and the control information are provided to the street lamp D corresponding to the transmission destination coordinate which is the final destination. The street lamp D recognizes that its node is the final destination based on the transmission node list information, and terminates the transmission of the control information. Therefore, in transmitting the control information from the gateway 203 to the street light 213, even if no street light is communicated with each street light, the control information is updated to the final node by newly setting the communication node by the minimum distance algorithm. Will be sent.

Here, each street light 213 holds the successful node information, that is, the communication ID information successful communication. For example, the success node information of the above-described street light P1 becomes P2, and the success node information of the street light P2 becomes P4. As such, success node information held by each street light 213 is used as an ID for quickly transmitting control information, event information, and the like, which is assumed to be the latest success ID information.

On the other hand, as a communication method for transmitting the event information to the server side of the individual control mode according to the present invention will be described with reference to FIG. First, each street light 213 holds the latest success ID information, and is registered and stored as the listed information. Therefore, each street light 213 holds a plurality of success ID information, and preferentially uses the latest success ID as the ID for connecting to the communication. Of course, when the communication is not performed by the latest successful ID information, the communication connection is performed using the success ID information registered subsequently.

As illustrated, when the street light O wants to provide its event information to the gateway 203 based on the recent success ID, the street light O transmits the event information to the P2 which is the latest success ID information (①). After receiving the event information of P0, the street light P2 performs communication based on the latest success ID information held by P2. If the last successful ID of P2 is P4, the street light P2 transmits cumulative event information to the street light P4 (②).

The cumulative event information is information accumulated by event information transmitted from an upper node and own event information, and the street light P2 receives its own event information and event information generated by the street light O. FIG. Therefore, the final street lamp D that transmits the event information to the gateway 203 transmits the event information transmitted from the upper node in a batch. The cumulative event information includes ID information of a street lamp passing along each path, and has status information of the street lamp, for example, lamp illuminance information, power information, and time information of detecting an event.

The event information is information stored in a memory provided in a control device interoperating with a communication module, and interlocked with a detection circuit for detecting a state of the street light 213. The detection circuit may be an illuminance sensor for detecting illuminance of a street lamp, a CT (Current Transformer) for detecting power consumption, or a ZCT (Zero Current Transformer) for detecting a power state of the street lamp.

The above-described detection circuit is mounted on the streetlight controller 211 provided in each of the streetlights 213, and the state information detected by the detection circuit is converted into a digital signal by an internal program of the control device and stored in the internal memory.

Meanwhile, the street light P2 communicates with P4, which is a recent success ID, and transmits cumulative event information therefrom. At this time, the street lamp P2 notifies the street lamp O that communication with P4 was successful (③). Therefore, the street light O maintains P2 which is the current success ID. In addition, the street lamp P4 attempts to transmit accumulated event information to the gateway 203 (④).

If the communication between the street light P4 and the gateway 203 is not made, that is, when a communication failure occurs, the street light P4 notifies the upper node P2 that the communication has not been performed due to the communication failure ( ⑤). At this time, the street lamp (P4) notifies the communication node to the upper node P2 and at the same time transmits its own event information. Accordingly, the street light P2 generates cumulative event information including the event information of P4 and resets its latest success ID information to the lowest rank.

That is, the street light P2 changes the priority of a plurality of successful ID information, and sets ID information that has failed current communication as the lowest priority, and sets the ID which was set as the second priority as the highest priority. Here, when the ID set as the second priority is P5, the street light P2 transmits cumulative event information to P5. If the street light P2 does not communicate with P5, the latest success ID information of the street light P2 is changed again, and the upper node PO is notified to reset the node path from the PO. do.

However, when the communication between the street lamp P2 and P5 is made, and the communication between the street lamp P5 and the gateway 203 is successful (6), P5 is registered as the latest success ID of the street lamp P2. The gateway 203 receives cumulative event information through P5 (⑦).

As described above, the cumulative event information includes event information for each street light, and includes route information including ID information for the transit node, and the gateway 203 knows an optimal communication route based on the route information. It becomes possible. That is, the gateway 203 secures a transmission success list. Here, the cumulative event information provided to the gateway 203 may not be provided only in one street light, but cumulative event information may be provided to the gateway 203 from two or more street lights according to the path of each street light.

On the other hand, the transmission success list is applied to the broadcast mode, by setting the path node in the reverse direction of the transmission success list, it is possible to collectively transmit the information. For example, when the lighting time of all the street lights 213 is to be changed, the gateway broadcasting method is used. 7 is a diagram illustrating gateway broadcasting according to a broadcast mode according to the present invention.

As shown, the gateway 213 transmits the reverse list information and the control information for the current successful transmission list information to the adjacent street lamp. Here, the adjacent street lamp is the last ID of the transmission success list, that is, the highest ID of the reverse list, and is at least one street lamp.

The street light corresponding to the highest ID of the reverse list receives the reverse list information currently received, and then changes the data, for example, the lighting time information according to the control information. The reverse list information and the control information are transmitted to at least one street lamp according to the reverse list.

Since the reverse list information is a list of the latest successful IDs, communication is attempted based on the node where communication was recently performed. Therefore, not only the communication connection probability is very high, but also the transmission speed for the control information for each street light is very fast. That is, when the same information is to be transmitted to each of the street lamps, the gateway broadcasting is used as in the present embodiment, thereby increasing the efficiency of data transmission.

In this embodiment, each street lamp continuously updates the latest success ID information, and the route information thereof is fed back to the gateway 213 to modify the transmission success list information.

According to the above method, the streetlight broadcasting method of the broadcast mode of the present invention is implemented in the same manner, and the streetlight broadcasting may be used when transferring information for the purpose of linkage between the street lamp and the street lamp. That is, it is applied to control the lighting of a plurality of street lights located in a category set to an arbitrary group. Thus, one particular street light is to broadcast to the street light in the group.
