BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a flow chart of a method of remote monitoring lighting fixtures in accordance with one embodiment of the disclosed technology. And Figure 2 is a block diagram of a lighting facility remote monitoring system 200 in accordance with one embodiment of the disclosed technology. First, the configuration of the lighting equipment remote monitoring system 200 will be described with reference to FIG. The lighting facility remote monitoring system 200 includes a lighting facility 210, a control center 220, and an administrator terminal 230. The lighting facility 210 includes a plurality of lights 211, a sensor module 210a, a control unit 210b and a communication unit 210c. The control center 220 includes a data receiving unit 220a and a data storage unit 220b ).

The lighting fixture 210 includes a plurality of lights 211. In one embodiment, it may be a lighting device having a plurality of lights used for a night game at a baseball field or a soccer field. The lighting fixture 210 is provided with a matrix-shaped illumination insertion portion having n rows and m columns and allows a plurality of lights to be respectively disposed therein. Referring to FIG. 3, the lighting equipment 210 may have a rectangular panel on a column that is embedded on the floor, and a placement hole such as a checkerboard may be formed on the panel, and a plurality of lights may be disposed thereon. The lighting facility 210 can operate the plurality of lights individually or uniformly according to the control signal of the control unit 210b to create an environment desired by the users.

Meanwhile, since the plurality of lights included in the lighting facility 210 maintain the indoor or outdoor illuminance in a specific environment, lifetimes and durabilities of the respective illuminations may be different from each other. For example, one of the plurality of lights may have a higher number of times of blinking than other lights, and the other of the plurality of lights may have a longer time to maintain the lighting state than the number of blink times. Therefore, since a plurality of lights are more frequently broken than failing, the manager has to visit the site on a regular basis to check the state of lighting to replace the failed light. In order to solve such a problem, in the present invention, the state values of the lighting equipment 210 and the plurality of lights 211 are checked through the sensor module 210a. If the state values are changed, the control unit 210b and the communication unit 210c to detect the location of the light source and to monitor the information on the remote site.

The sensor module 210a senses the lighting equipment 210 periodically. And detects that the state value of the lighting equipment 210 fluctuates. In one embodiment, a plurality of sensor modules 210a are disposed in the lighting equipment 210, and the sensor module 210a is disposed in a region where power is applied to the lighting equipment and a region where the power is branched and applied to the respective lights, 210 can be powered normally, and whether the lights connected to each branch are operating normally.

In order to perform the above-described operation, the sensor module 210a includes at least one of a voltage sensor, a current sensor, a vibration sensor, and a magnetic field sensor. In one embodiment, The sensor module e installed in the supplied area can detect whether power is supplied to the lighting equipment 210 or whether the state of the supplied power is normal or not using the sensors. The sensor modules a to d arranged for each branch can detect the presence or absence of a power source applied to the illumination, the state of the power source, the intensity or balance of the magnetic field to be formed, and the vibration value generated in the connected illumination.

Generally, a lighting device that illuminates the surroundings using electric power generates a voltage and a current in accordance with supply and demand of electric power, and a magnetic field is formed around the electric power. Accordingly, the sensor module 210a can monitor such voltage, current, and magnetic field to detect whether the lighting fixture 210 is operating properly. If some of the plurality of lights are out of order, the sensor module 210a senses the difference of the state values so that the abnormality of the lighting equipment 210 is detected Can be detected. At this time, the value sensed by the sensor module 210a may exceed the threshold value or may exceed the threshold value negatively. Therefore, it is preferable to judge whether the absolute value is exceeded or not.

In sensing the state value of the lighting fixture 210, the sensor module 210a operates according to a predetermined period. For example, it is possible to detect whether an abnormality has occurred by comparing a currently stored default value with a currently sensed status value. Here, the period of the operation of the sensor module 210a may be adjusted by the manager of the system 200 to an arbitrary value according to the area where the lighting equipment 210 is disposed.

Meanwhile, the controller 210b determines whether the changed state value exceeds a predetermined threshold value. In one embodiment, the controller 210b includes a PLC, and if the threshold value set in the PLC exceeds the status value of the lighting facility 210, It can be judged that the lighting has failed. If the state value does not exceed the threshold value, the control unit 210b can determine that the lighting equipment 210 is operating normally.

On the other hand, when the controller 210b determines that the changed state value exceeds the threshold value, the controller 210b checks which of the state values received from each sensor module exceeds the threshold value. In an embodiment, the control unit 210b may include layout information for each of a plurality of lights connected to each other in order to check which of the plurality of lights included in the lighting equipment 210 is broken, State values can be mapped. Referring to FIG. 4, it can be seen that the positions where a plurality of lights are arranged are divided according to n rows and m columns. In one embodiment, the control unit 210b sequentially assigns numbering to n rows and m columns, sets and stores a unique coordinate value for each of a plurality of lights, and stores a state value received from the plurality of sensor modules 210a Which is a coordinate value mapped to a specific state value exceeding a threshold value.

In addition, the controller 210b can further receive data for predicting the remaining life of each illumination from the sensor module 210a that senses the state value of each illumination and for replacing some illumination. In one embodiment, the control unit 210b receives the number of blinking times for each light and the time the illumination is kept turned on from the sensor module 210a and may generate a replacement notification for some of the lights that exceed the reference value .

On the other hand, the control unit 210b generates information on a location where the lighting equipment 210 is installed using the pre-stored map data. In one embodiment, the map API may be used to transmit information or coordinates for the area in which the lighting fixture 210 is installed to the control center 220 along with a replacement notification.

5, it can be confirmed that the sensor module 210a detects the failure of the specific illumination according to steps S510 through S530. The sensor module 210a senses the power applied to the lighting equipment 210 in step S510. If power is not applied to the lighting equipment 210, the sensor module 210a transmits a signal to the control unit 210b in step S520, and the control unit 210b notifies the lighting equipment 210 of abnormality It is possible to transmit a notification to the control center 220 or the administrator terminal 230 that the notification has occurred. If it is detected in step S510 that the power is applied, the sensor module 210a counts the number of blinking times and the holding time of the light through steps S530 and S540. For example, it is possible to count the number of times of blinking and the holding time by detecting the flow of current or voltage, the amount of heat generated by illumination, and the illuminance. Various kinds of sensors for this purpose may be additionally provided in the sensor module 210a.

Meanwhile, the sensor module 210a transmits information on the number of times of blinking of the counted lights and the holding time to the controller 210b. If the number of times of blinking and the holding time of the illumination exceeds the reference value based on the received information, the control unit generates a replacement notification for the corresponding illumination. If the reference value is not exceeded, the controller 210b can continue to transmit a predetermined control signal so that the sensor module 210a counts the number of times of blinking and the holding time. The control unit 210b transmits the replacement notification generated through the communication unit in step S550. Here, the control unit 210b may transmit information on the position of the illumination together with the replacement notification. For example, as shown in FIG. 4, a replacement notification for lighting located at the coordinates (n2, m1) may be transmitted to the control center 220 or the administrator terminal 230.

The communication unit 210c transmits location information on the failed illumination generated by the control unit 210b to the control center 260. [ In one embodiment, the communication unit 210c includes a wireless module supporting LTE communication, and can transmit location information generated by the control unit 210b to the control center 220 or the administrator terminal 230 using a wireless communication network . On the other hand, information transmitted here is stored in the control center 220 in chronological order. For example, the control center 220 may receive a replacement notification from the control unit through the data receiving unit 220a and write it in the data storage unit 220b.

On the other hand, the communication unit 210c can transmit the replacement notification using the VPN. In one embodiment, the communication unit 210c may establish a private network that is disconnected from the outside and directly communicates with the control center 220, thereby safely transmitting the replacement notification through the private network. Likewise, the smart terminal 230 of the administrator can transmit the location information through the path blocked from the outside using the VPN scheme. Of course, it is also possible to connect through a leased line, but the price or maintenance cost of the construction is rather high compared to the VPN, and since the location information itself does not have a lot of data, it is possible to transmit data smoothly even at a relatively slow speed of the VPN It is preferable to use them.

Meanwhile, referring to FIG. 6, the manager can monitor the status of each lighting equipment at a glance using a predetermined application. For example, it may indicate the location of all lighting fixtures present on the map data and verify whether each lighting fixture is operating normally. Or a plurality of managers may set to display only some of the lighting fixtures belonging to the respective ones of them, and monitor the status of the certain lighting fixtures.

On the other hand, the administrator can perform monitoring on the screen of FIG. 6 in the administrator terminal 230 or the control center 220. Then, information such as the position of the failed lighting, the number of blinking times, and the holding time can be confirmed through the predetermined interface provided on the screen. It can also monitor the information detected from the sensor module installed in the lighting fixture. By monitoring various kinds of information about lighting equipment, it can easily manage the lighting facilities from a remote place.

Although the lighting equipment remote monitoring method and system according to an embodiment of the disclosed technology has been described with reference to the embodiments shown in the drawings for the purpose of understanding, it is to be understood that those skilled in the art will only be able to It will be understood that various modifications and equivalent embodiments are possible.
