Other objects and features of the present invention in addition to the above objects will be apparent from the description of the embodiments with reference to the accompanying drawings.

Hereinafter, a street lamp control system according to an embodiment of the present invention will be described in detail with reference to FIGS. 2 to 6. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Figure 2 shows a streetlight control system according to an embodiment of the present invention.

As can be seen in Figure 2, the system divides a plurality of street lights installed in a certain area into a plurality of groups (first group to N-th group), the distribution panel is installed on both sides of the divided group, each group is a first sub The first subgroup is divided into a group and a second subgroup, and the divided first subgroup receives power through a power switching unit of a distribution panel installed on one side, and the second subgroup receives power through a power switching unit of a distribution panel installed on the other side. .

Here, the first subgroup may be a group consisting of odd-numbered streetlights among the plurality of streetlights included in the group, and the second subgroup may be a group consisting of even-numbered streetlights among the streetlights of the group. It may be configured as an even street light, or the second subgroup may be configured as an odd street light.

That is, the distribution panel is configured to supply power to the street lamps constituting the second subgroup of the first group when the distribution panel is the first distribution panel (distribution panel 1), and constitutes the first subgroup of the second group. The power is supplied to the street lights, and when an abnormal state is detected in the street lights constituting the first subgroup of the first group, the lamps are included in the first subgroup of the first group through a power switching unit separately provided in the left circuit of the first distribution panel. Detecting abnormal state among the street lamps that supply power to the street lamps located on the right side of the street lamp, and when an abnormal state is detected in the street lamps constituting the second subgroup of the second group, a power switching unit separately provided in the right circuit of the first distribution panel. Power is supplied to the street lamps located to the left of the abnormal state detection street lamps among the street lamps included in the second subgroup of the second group.

When the control center receives the information on the abnormal condition of the street lamp through communication with the distribution panel, the control center notifies the administrator of the problem and issues a power off command to the left and right street lamps of the corresponding street lamp in which the abnormal condition is detected. It cuts off the power and allows power to be supplied to the remaining street lights except the street lamp in which an abnormal condition occurs.

At this time, the control center may notify the administrator through an alarm, a text message, and the like.

In addition, the control center is connected to the power switching unit provided separately in the left circuit and the right circuit of the distribution panel, for example, in order to supply power to the street lamp does not have a problem, for example, the street lamp connected through ③ in the first distribution panel Control the power control switching circuit of C1 to supply power or control the power control switching circuit of C2, which is the street light connected through ④ to supply power, and then issue the inspection command of the troubled street light. Allow to check

FIG. 3 is a diagram illustrating an embodiment of the distribution panel shown in FIG. 2.

As can be seen in FIG. 3, it can be seen that the distribution panel includes a right circuit for supplying power to the street lamps constituting the first subgroup and a left circuit for supplying power to the street lamps constituting the second subgroup. Includes a communication module, a data storage and processing module, and two power switching units.

The communication module is a module for communicating with the control center. When an abnormal state is detected in the streetlights constituting the subgroup, the communication module transmits information to the control center, and command signals such as power off or power supply of the streetlight from the control center. Receive

In this case, the communication module may be a communication module using a specific method, for example, a communication module using a low power wireless communication method (zigbee). Of course, it is obvious that communication modules using other methods can be used.

The data storage and processing module stores data about a module processing an operation of a corresponding circuit side and a street lamp included in a corresponding subgroup, and receives and stores information sensed by a voltage or current sensor included in the street lamp. When an abnormal condition is detected, it performs general functions such as transmitting information about this to the control center through a communication module.

The first power switching unit to the second power switching unit are voltage or current breakers, and the first power switching unit and the second power switching unit respectively supply power to the street lights constituting the second subgroup of the left group and the first subgroup of the right group. To provide.

The third power switching unit is a switching means for supplying power to the street lamp located on the right side of the corresponding street lamp where the abnormal condition occurs when the abnormal state occurs in the first subgroup of the neighboring left panel. When the abnormal state occurs in the second subgroup of the right distribution panel switching means for supplying power to the street lamp located on the left side of the corresponding street lamp in which the abnormal condition occurs, the switching unit connected to ③ in FIG. And a switching unit connected to ④ may be a fourth power switching unit.

In this case, the power switching unit illustrated in FIG. 3 may be a circuit breaker capable of blocking an abnormal current or more suitable for the corresponding subgroup.

Of course, the two power switching units provided in the left circuit and the right circuit may be configured as one power switching unit, but since this may increase the cost of constructing the system, the two power switching units may be configured to form the corresponding subgroups and neighbors. Perform power supply for subgroups.

For example, if the appropriate breaker for a subgroup is a 100A breaker, one 200A breaker can serve as two 100A breakers, but in this case, using two 100A breakers is less than the contract power. Since the cost of using the power can be reduced, the cost of configuring the system can be reduced.

As described above, power may be separately provided to the right and left circuits of the present invention to supply power to a normally operating street lamp configured in the neighboring subgroup in which an abnormal state is detected.

In the system according to an embodiment of the present invention by configuring the street lamp as shown in Figure 4, it is possible to cut off the power around the street lamp where the safety problem occurs, and supply the street lamp power without problems to another supply route.

That is, by configuring a switching circuit as shown in Figure 4, it is possible to control the power supply of the street light from both the left and right.

In addition, one power control switching circuit of FIG. 4 is installed in each street lamp column. The switching circuit operates a circuit on the left and right sides of a troubled street lamp to completely cut off power to the troubled street lamp.

For this purpose, if a current (or voltage) above the set safety level is detected through the current or voltage sensor included in the street light, the data (current value or voltage value) is transmitted to the data storage and processing module in the distribution panel shown in FIG. To be transmitted to the control center through the communication module.

FIG. 5 is an exemplary diagram for describing an operation of a streetlight control system according to an exemplary embodiment of the present invention, in which an abnormal state occurs in the streetlight G13 of the first group.

Referring to the operation, when data on a short circuit or a dangerous situation is transmitted from the street lamp G13 to the control center through the distribution panel, the control center opens the left power switching circuit of the left street lamp G11 and the right power lamp circuit of the right street lamp G15. Send a command to open to completely disconnect the street lamp (G13) from the power supply.

At this time, the third power switching unit provided in the first distribution panel so that the street lamps G15, G17, ..., G1 (n-1) does not have any abnormality and the power supply is cut off so that the lamp is not turned on. If it is turned on, it can be turned on again by applying power to the street lights G1 (n-1) to G15 through the installed power line ③.

In FIG. 5, G1 means a first group, and a second number is an identification number indicating a location of a corresponding street light. For example, G13 means a third street light of the first group.

Therefore, when the power control operation is completed, the control center contacts the company in charge of the maintenance of the area and checks and repairs the street lamp. After the repair is completed, the control center controls the power in the reverse order in case of abnormality. Return the system to the system configuration.

As described above, the street lamp control system according to an exemplary embodiment of the present invention provides a neighboring subgroup when an abnormal state is detected in a streetlight of a power switching unit for supplying power to a corresponding subgroup and a neighboring subgroup supplied with power from a neighboring distribution panel. A separate power switching unit is provided for supplying power to a part of the lamp to supply power to a street lamp except for a street lamp in which an abnormal state is detected, and to light a street lamp, and to separately provide a current breaker corresponding to a corresponding subgroup and an adjacent subgroup. This can reduce the cost of constructing and using a safety-considered system.

Figure 6 shows a streetlight control system according to another embodiment of the present invention.

As shown in FIG. 6, unlike FIG. 2, the system divides a plurality of street lights installed in a region into a plurality of groups (first to Nth groups), and divides each group into a left subgroup and a right subgroup. And a distribution panel (first distribution panel to N-th distribution panel) is installed at the center thereof, and the street lamp constituting the left subgroup has a power line (⑤) connected to the first power switching unit configured in the left circuit of the distribution panel, as shown in FIG. The power is supplied through the power supply, and the street light constituting the right subgroup is supplied with power through the power line (6) connected to the second power switch configured in the right circuit of the distribution panel.

Of course, when the abnormal state is detected by the street lamps configured in the neighboring groups, the distribution panel may use the power switching unit provided separately in the left circuit or the right circuit, that is, by using the third power switching unit or the fourth power switching unit shown in FIG. 3. The lamp can be turned on except for the street lamp in which the status is detected. For example, when an abnormality is detected in the street lamps configured in the right group of the third group, the third power switching unit configured in the left circuit of the first distribution panel is connected (⑦) to the right street lamps configured in the right group of the third group. When the power is supplied through the first distribution panel and an abnormality is detected in the street lamp configured in the left group of the second group, the leftmost street lamp configured in the left group of the second group using the fourth power switching unit configured in the right circuit of the first distribution panel. By connecting (⑧) and supplying power through the first distribution panel, power can be turned on by supplying power to the remaining street lamps except for the street lamp in which an abnormal condition is detected.
