In addition, the terms “… unit”, “… unit”, “module”, etc. described in the specification mean a unit that processes at least one function or operation, which may be implemented by hardware or software or a combination of hardware and software. have.

Hereinafter, a remote control system and method for a street lamp / security lamp according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the present invention, the system and method for remotely controlling a plurality of street lights are the same as the system and method for remotely controlling a plurality of security lights, and thus, the security lights will be described below.

1 is a block diagram of a remote control system for a street lamp / security lamp according to an embodiment of the present invention, Figure 2 is a block diagram of a group setting message and a group control message, Figure 3 is a configuration of a terminal according to an embodiment of the present invention 4 is a block diagram of an eye lamp state detecting unit according to an exemplary embodiment of the present invention.

As shown in FIG. 1, a remote control system such as a street light / security light includes a host computer 100, a plurality of repeaters 200, and a plurality of terminals 300.

The plurality of repeaters 200 are connected to one host computer 100 by Ethernet, such as LAN and the Internet, and the plurality of terminals 300 are connected to one repeater 200 through wireless communication, The terminals 300 communicate with each other based on the IEEE 802.15.4 MAC structure, and one terminal is installed in one security light. Hereinafter, for convenience of description, it will be described on behalf of one repeater 200 and one terminal 300.

The host computer 100 displays the locations of a plurality of security lights on a map, and the user of the host computer 100 may select a plurality of security lights that the group control is desired from among the plurality of security lights and group them into one group. The control command may be collectively indicated according to the grouped group.

More specifically, when a user of the host computer 100 assigns a plurality of security lights to any desired group, a "group setting message" including a group identification is generated and transmitted to the relay 200.

As shown in FIG. 2, the group setting message 10 includes a repeater ID 11, a terminal ID 12, and a group ID 13. The repeater ID 11 is an ID of a repeater connected to a terminal to be grouped among the plurality of repeaters 200, and the terminal ID 12 is an ID of a terminal to be grouped among the plurality of terminals 300. The group ID 13 is an ID of a group that software-connects one or more terminals to be grouped. A plurality of repeater IDs 11 and a plurality of terminal IDs 12 may be given to the same group ID 13. At this time, the group setting message 10 is not generated such that two or more group IDs 13 are assigned to one terminal ID 12.

Thus, in the present invention, by assigning one group ID 13 to a plurality of security lights desired by the user of the host computer 100, the security lights can be randomly grouped regardless of the physical positions of the plurality of security lights.

In addition, when the host computer 100 inputs a "response message" (not shown) informing the group setting success from the repeater 200, the "group control message" (20) for collectively controlling the plurality of terminals 300 for each group (20). ) Is generated and transmitted to the repeater 200, and monitors the status of the security light through the feedback message is fed back.

When a signal indicating an error is input from the repeater 200 during the monitoring process, the host computer 100 requests the repair of the terminal 300 to a company or a person in charge of repairing a security, etc., in which the terminal 300 which has sent an error signal is mounted. Send a message.

As described above, in the present invention, by controlling security for each group, a plurality of security lights can be collectively controlled regardless of the physical location. In addition, the host computer 100 may prevent the loss of message packets by controlling each group after a response message indicating that group setting is completed from all terminals 300 included in each group is input.

The repeater 200 serves as a gateway that connects communication between the host computer 100 and the terminal 300. More specifically, when the repeater ID 11 of the group setting message 10 input from the host computer 100 is the same as the ID of the stored repeater 200, the repeater 200 subordinates all of the group setting message 10 to the lower part of the group setting message 10. If not, the group setting message 10 is discarded.

In addition, the repeater 200 transmits a response message received from the terminal 300 to the host computer 100.

The terminal 300 receives the group setting message 10 and the group control message 20 from the repeater 200, generates a response message for allowing a plurality of security lights to be controlled for each group, and transmits the response message to the repeater 200.

As shown in FIG. 3, the terminal 300 includes a lower terminal presence determining unit 310, a message determining unit 320, a group determining unit 330, a group ID storing unit 340, and a response message generating unit 350. It includes a group ID verification unit 360, a control unit 370 and the security state detection unit 380.

The lower terminal presence determining unit 310 determines whether there is a lower terminal connected through wireless communication, and when the lower terminal exists, the group setting message 10 and the group control message 20 inputted from the relay 200 are bidirectional. Transmit to the lower terminal through the antenna. In addition, the lower terminal presence determination unit 310 transmits various response messages input from the lower terminal to the repeater 200 or the upper terminal 300.

The message determining unit 320 determines which message is a message input through the antenna and outputs the classified message. The message determining unit 320 outputs the group setting message 10 to the group determining unit 330 when the input message is the group setting message 10, and when the input message is the group control message 20, the group control message ( 20) to the group ID verification unit 360.

The group determining unit 330 compares the terminal ID 12 of the group setting message 10 with the set ID of the corresponding terminal 300, so that the terminal ID 12 of the group setting message 10 is different from the terminal ID. If so, the group setting message 10 is discarded. However, when the terminal ID 12 of the group setting message 10 matches the ID of the corresponding terminal, the group ID stored in the group ID storage unit 340 is compared with the group ID 13 of the group setting message 10. do. If the group ID stored in the group ID storage unit 340 is different from the group ID 13 of the group setting message 10, the group determination unit 330 outputs a group ID reset control signal to the group ID storage unit 340. do.

When the group ID reset control signal is input from the group determination unit 330, the group ID storage unit 340 resets the group ID of the group ID storage unit 340 to the group ID 13 of the group setting message 10.

When the response message generator 350 is connected to the group determiner 330 and the group ID reset control signal is output from the group determiner 330, the response message generator 350 generates a group ID setting corresponding to the group set message 10. A success message "(not shown) is generated as a response message and transmitted to the repeater 200 or the upper terminal 300.

In addition, the response message generator 350 generates a response message according to the control signal input from the controller 370 and transmits the response message to the repeater 200 or the upper terminal 300.

The group ID verification unit 360 compares whether the group ID 21 of the group control message 20 matches the group ID of the corresponding terminal, so that the group ID 21 described in the group control message 20 corresponds to the group of the corresponding terminal. If it is different from the ID, the group control message 20 is discarded. However, when the group ID 21 described in the group control message 20 matches the group ID of the corresponding terminal, the controller 370 outputs the control message 20 included in the group control message 20.

The control unit 370 reads the control message 22 to execute a command included in the control message 22 and generates a response message corresponding to the command, such as a security light state detection unit 380 and a response message generator ( Control 350).

The security lamp state detector 380 is connected to the controller 370, and detects various states such as security according to a control signal input from the controller 370, and outputs the result to the controller 370.

Here, the control message 22 is a command for reporting various states such as the on / off state of the security light, the light quantity state, the inverter operation state, etc., as well as the dimming according to the signal and the light amount for resetting the on / off time of the security light. The control signal may include a control signal for converting a state of security, such as an on / off real-time blinking signal such as security.

Hereinafter, a case in which the control message 22 is an instruction to report an on / off state of security or the like will be described. Of course, the on / off status report such as security may be reported in real time from the terminal even when there is no control message.

When the control message 22 is a command to report an on / off state of the security light, the controller 370 outputs a control signal to detect the security light on / off state to the security light state detection unit 380.

Referring to FIG. 4, the security light state detector 380 includes a CT sensor 381, a comparator 382, a pulse determiner 383, and a security light state detector 384. do.

The CT sensor 381 is provided between an AC power input terminal and an inverter such as a security to detect a current.

The positive terminal of the comparator 382 is connected to the output terminal of the CT sensor 381, and the negative terminal of the comparator 382 is connected to a reference current. Here, the reference current is set to a current value detected when the lamp operates normally when the lamp is off and the inverter is off.

The comparator 382 outputs a high signal when the current detected by the CT sensor 381 is greater than or equal to the reference current, and outputs a low signal when the current detected by the CT sensor 381 is less than the reference current, and the output waveform thereof is shown in FIG. 5. As shown in the pulse waveform.

5A to 5C illustrate output waveforms of the comparator 382 according to an embodiment of the present invention. FIG. 5A is an output waveform of the comparator 382 when the inverter is off and the lamp is off, and FIG. 5B is an inverter. Is the output waveform of the comparator 382 when is on and the lamp is off, and FIG. 5C is the output waveform of the comparator 382 when the inverter is on and the lamp is on.

The inverter is an element that boosts AC current and applies it to the lamp. When the inverter is abnormally operated (off), the lamp is turned off. Therefore, as shown in FIG. 5A, no current is consumed in the inverter and the lamp, so that the output of the comparator is maintained at 0V.

Even if the inverter normally applies current to the lamp, the lamp may be turned off in the event of a lamp failure. When the lamp is off and only the inverter is operating, the pulse width of all waveforms output from the comparator 382 for 16.66 ms (1/60 Hz) does not exceed approximately 3 ms, as shown in FIG. 5B. At this time, it is assumed that 3ms is larger than the maximum width of the output pulse when only the inverter is driven and less than the minimum width of the output pulse when the inverter is driven and the lamp is on.

That is, when the current is not consumed in the lamp and only the inverter consumes current, there is a limit in the period during which the waveform output from the comparator 382 maintains a high signal.

Next, when the inverter normally applies current to the lamp and the lamp is turned on, as shown in FIG. 5C, there are waveforms exceeding 3 ms among the waveforms output from the comparator 382 for 16.66 ms.

As described above, in the present invention, the operating states of the lamp and the inverter can be grasped through the output waveform output from the comparator 382.

More specifically, the pulse determiner 383 may include a first reference pulse width (3 ms in FIGS. 5B and 5C) of the plurality of pulses output from the comparator 382 during the first time (16.66 ms in FIGS. 5A to 5C). It is determined whether there is an abnormal pulse, and the result value is output to the security lamp state detector 384. At this time, the first pulse width is determined by the rated power consumption detected by the normal lamp when the security light is on.

At this time, when the pulse determination unit 383 determines that there is no pulse that is equal to or greater than the first reference pulse width among the plurality of pulses output from the comparator 382 for the first time, the security lamp state detector 384 turns off the lamp of the security lamp. The detection signal indicating the in state is output to the controller 370.

In addition, when the pulse determination unit 383 determines that there is a pulse that is equal to or greater than the first reference pulse width among the plurality of pulses output from the comparator 382 for the first time, the security lamp state detector 384 performs a pulse for a predetermined time. Based on the number and the pulse width, a detection signal indicating an operation state of the inverter and the security lamp is output to the controller 370.

That is, the security lamp state detector 384 outputs a detection signal indicating the operation state of the inverter to the controller 370 according to the number of pulses input during the second time (16.66 ms of FIGS. 5A to 5C). More specifically, when the number of pulses input for the second time is greater than or equal to the first reference number, the security lamp state detector 384 outputs a signal to the controller 370 that determines that the inverter is normally operated, and inputs the pulse for the second time. If the number is less than the first reference number, the controller 370 outputs a signal indicating that the inverter is not operating normally.

The security light state detector 384 detects a detection signal indicating an on / off state of the lamp (included in the security light) according to the pulse width of the longest pulse among the pulses input during the third time (16.66 ms of FIGS. 5A to 5C). Output More specifically, the security light state detector 384 outputs a signal to the controller 370 that the lamp is on when the pulse having the longest pulse width among the pulses input for the third time is kept high for more than the fourth time. When the pulse having the longest pulse width among the pulses input for the third time is kept high for less than the fourth time, a signal indicating that the lamp is off is output to the controller 370.

In this case, the first to fourth times are determined by the driving frequency of the lamp, the rated power consumption of the lamp, and the like.

The control unit 370 outputs a control signal to the response message generating unit 350 according to the security light on or off state signal of the lamp state detector 385, and the response message generating unit 350 determines whether the lamp of the security light is on or off. A response message for acknowledgment is generated and the response message is transmitted to the relay 200 or the upper terminal 300.

As described above, the present invention converts the current value output from the CT sensor 381 into a digital signal having high / low by using a comparator 382 such as an OP amplifier instead of an analog-to-digital converter, thereby simplifying circuit implementation and providing circuitry. The implementation cost can be greatly reduced. In addition, the output waveform of the comparator 382 can be used to determine an on / off state such as security or the like, and can also determine whether or not an inverter has failed.

6 is a flowchart illustrating a remote control method for a street lamp / security lamp according to an exemplary embodiment of the present invention.

As shown in FIG. 6, the user may group the plurality of terminals 300 into one first group through the host computer 100 regardless of the physical location (S601).

Referring to FIG. 1, a user groups a desired terminal into one group regardless of the physical locations of the 1-N terminals connected to the first repeater and the N-2 terminal connected to the N repeater among the plurality of repeaters 200. can do. That is, the user sets up a group based on an environment such as security regardless of the physical location.

Looking at the environment in which the user groups the security light, if the installation of the new security light is added to the facility and the building is added to the place where the existing security light is installed, group the additional security lights in the same group as the surrounding security lights. Then, additionally installed security can be controlled without a separate line construction.

Looking at other cases in which the user groups security, etc., the user can be grouped according to a high crime rate, a middle area and a low area. And, the higher the crime rate, the brighter the brightness of the security light, the crime rate can be lowered.

Looking at another case in which the user groups the security light, it can be grouped into a distant area, an entire lights out area and an area to be always on according to the surrounding environment. Then, the flashing of the security light for each group is controlled to save energy generated by turning on unnecessary security light.

Following step S601, the host computer 100 may include a group setting message 10 including one or more relay IDs included in the first group, one or more terminal IDs included in the first group, and a group ID of the first group. Generate (S602), and transmits the generated group setting message 10 to all repeaters 200 (S603).

All repeaters 200 compares the repeater ID of the group setting message 10 with the corresponding ID of the repeater (S604), and if the group setting message 10 does not have the ID of the corresponding repeater, discards the group setting message 10. (S605). However, if there is an ID of the repeater in the group setting message 10, the group setting message 10 is transmitted to all the plurality of terminals connected below (S606).

 All the plurality of terminals 300 compares the terminal ID of the group setting message 10 with the ID of the corresponding terminal (S607). At this time, all the plurality of terminals 300 determines whether there is another terminal below, and if there is another terminal below, transmits the group setting message 10 to the lower terminal (S608).

When the plurality of terminals 300 do not have an ID of the corresponding terminal in the group setting message 10, the terminal 300 discards the group setting message 10 (S609). However, if there is an ID of the corresponding terminal in the group setting message 10, the terminal of the first group sets the group ID as the first group ID included in the group setting message 10 (S610).

The terminal of the first group generates a response message indicating that the terminal ID is set to the first group ID and transmits the response message to the host computer 100 through the repeater 200 (S611).

The host computer 100 waits until a response message indicating completion of group setting is received from all terminals of the first group (S612).

As described above, in the present invention, the next control operation is stopped until the group setting completion response message is input from all terminals included in one group, thereby preventing the packet from being lost in the process of transmitting the group setting message.

When a response message indicating completion of group setting is received from all terminals of the first group, the host computer 20 includes a first group ID 21 and a group control message 20 including a control message 22 to be controlled for each group. Generate and transmit to all repeaters 200 (S613). All the repeaters 200 transmit the group control message 20 to all the terminals 300 below (S614).

As described above, according to the present invention, by transmitting a message controlled by each group after the grouping by a broadcasting method, it is possible to remotely control security and the like for each group and to shorten the time for controlling.

After step S613, all the terminals 200 compare the first group ID 21 of the group control message 20 with the group ID of the corresponding terminal (S615). At this time, all the terminals 200 determine whether there is another terminal below, and if there is another terminal below, and transmits a group control message to the lower terminal (S616).

If all of the plurality of terminals 300 do not have a group ID of the corresponding terminal in the group control message 20, the terminal control message 20 discards the group control message 20 (S617). However, if there is a group ID of the corresponding terminal in the group control message 20, the terminal of the first group controls the security connected according to the control message 22 command included in the group control message 20 (S618). .

7 is a flowchart illustrating a streetlight / security lamp control method according to a group control message according to an exemplary embodiment of the present invention. In this case, for convenience of description, it will be described on the assumption that the control message 22 of the group control message 20 is a message for reporting on / off status of security light.

As shown in FIG. 7, the terminal of the first group receives the control message 22 of the group control message 20 to report the on / off status of the security light (S701). Then, the current is detected using the CT sensor 381 provided between the AC power input terminal for inputting the AC power to the security lamp and the security lamp (S702). The comparator 382 compares the output current of the CT sensor 381 input with the (+) terminal and the reference current input with the (-) terminal (S703), and if the output current of the CT sensor 381 is equal to or greater than the reference current When the output signal of the CT sensor 381 is less than the reference current and has a high signal, a pulse waveform having a low signal is output (S704).

The pulse determiner 383 checks whether there is a pulse greater than or equal to the first reference pulse width among the pulse waveforms of the comparator 382 during the first set time (S705). If there is no pulse greater than or equal to the first pulse width by the pulse determiner 383, the security lamp state detector 384 outputs a signal to the controller 370 that determines that the lamp of the security lamp is in an off state (S706).

However, when there is a pulse that is greater than or equal to the first reference pulse width in the pulse determiner 383, the security lamp state detector 384 compares the width of the longest pulse among the input pulses for a predetermined time with the set pulse width (S707). When the width of the longest pulse is greater than or equal to the set pulse width, a signal that determines that the lamp of the security lamp is on is output to the controller 370 (S708). When the width of the longest pulse is less than the set pulse width, the lamp of the security lamp is output. The signal determined to be in the off state is output to the control unit 370 (S709).

Then, the controller 370 outputs a control signal to the response message generator 350 to generate a response message indicating an on / off state of the security lamp, and the response message generator 350 controls the controller 370. A response message is generated according to the signal (S710).

The response message is transmitted to the host computer 100 through the relay 200 (S711). The host computer 100 user may monitor the on / off state of the security light lamp in real time through a response message.

If the control message 22 of the group control message 20 receives a message for reporting the operation state of the inverter in step S701 of FIG. 7, the security light state detector 384 is input in step S706. If the number of pulses per hour of the comparator is greater than or equal to the reference number, the controller 370 outputs a signal indicating that the inverter is operating normally. If the number of pulses per hour is less than the reference number, the signal is output to the controller 370 indicating that the inverter is abnormally operated.

Then, the control unit 370 outputs a control signal to the response message generator 350 as in step S710, the response message generator 350 generates a response message indicating the inverter operation state to the repeater 200 Transfer to the host computer 100 via. The host computer 100 user may monitor the operation state of the inverter in real time through a response message.
