Description

Street lighting system capable of integrated management of facilities around roads {Street Surrounding Installations Manageable Street Lamp System}

The present invention relates to a streetlight system capable of integrated management of roadside facilities. In particular, it relates to a streetlight system capable of integrated management of roadside facilities, which is capable of supplying power to many types of roadside facilities 24 hours a day and enabling integrated management of power requirements.

As is well known, damage to streetlight distribution lines frequently occurs due to various civil engineering works, including gas pipe construction and water pipe construction, which are mostly performed during the day. Therefore, in reality, power is supplied limitedly to street lights connected in groups through street light distribution boxes only at night when construction is not being carried out. On the other hand, in recent years, many roadside facilities that use power lines, such as CCTV, noise measurement sensors, fine dust detection sensors, Wi-Fi, mobile communication repeaters, electric vehicle charging facilities, and solar panels, have been installed around the roads, and these devices are all of considerable size. Power supply is required, and since power is not supplied to street lights during the day, power is not provided from street lights. Therefore, separate distribution line facility construction is being carried out to enable day and night-only power supply separately from street lights. Therefore, as the construction of distribution lines for facilities near many roads is carried out overlappingly, a huge amount of budget is wasted, and traffic on roads and sidewalks is inevitably blocked for frequent construction, resulting in civil complaints. Moreover, during this excavation process, streetlight distribution lines and other distribution lines are often broken or their coverings are damaged, causing many problems such as damage to power equipment and electric shocks due to electric leaks and short circuits.

In order to solve this problem, according to Republic of Korea Patent Publication No. 10-0808968 (title of the invention: real-time automatic notification system for abnormalities in streetlight cables and streetlight facilities; hereinafter referred to as the "cited invention") filed by the present applicant, as shown in Figure 1 As shown, the streetlight distribution box (20) includes an RTU consisting of a CDMA module and a communication unit, and the magnet contact point (23) is controlled by a circuit breaker and a flasher; A street light pole (12) provided with a ballast (10) and a lamp (11); A cable (30) and a connection part installed to connect the streetlight distribution box (20) and the streetlight pole (12); In the real-time automatic notification system for a known streetlight abnormality in which the status information of the streetlight distribution box (20), streetlight pole (12), or cable is transmitted to the control server (50) via CDMA, the Internet, or wired/wireless communication,

Displacement detection means (60) installed on the tracks inside the street light pole (12) and consisting of various sensors connected to one of the tracks,

A monitoring power circuit (29) installed in the streetlight distribution box (20) and connected to one of the lines to monitor the output of the displacement detection means (60),

The output of the displacement detection means 60 detected by the monitoring power circuit 29 is transmitted to the above-mentioned known RTU 40 so that the RTU 40 transmits predetermined abnormality display data to the control server 50.

Accordingly, the cited invention states that at night, the magnet contact point 23 is turned on by the operation of the streetlight flasher 21, so that power (R, N) is supplied to the ballast 10 of the streetlight pole 12 via the cable 30. The lamp 11 lights up.

In addition, in the cited invention, the time relay 71 operates during the day and the time relay contact 72 is turned off, so the magnet contact 23 is turned off and the power of the power sources (R, N) supplied through the cable is cut off.

In addition, during the day, as the time 2 relay 73 is activated and the contact point of the time 2 relay 74 is turned on, a safety low voltage is transmitted from the transformer 26 and the rectifier 27 via one end of the cable 30 to the displacement detection means 60. ), damage to cables or damage to cable connection parts occurs during daytime construction of water pipes, power lines, and gas pipes, or damage from collision with the streetlight pole (12) when driving or parking the vehicle in reverse, and this is quickly detected by a displacement detection device. Detected by (60), the sensor relay contact point (84) is activated and the transmission relay (85) is activated, which activates the RTU (40) and the streetlight line connected to the streetlight distribution box (20) at a certain location in the control server (50). It is possible to recognize in real time whether something is wrong with the facility. Therefore, in the cited invention, since power (R, N) is not supplied to the cable 30 during the day, power supply to the streetlight pole 12 is impossible, and CCTV, noise measurement sensors, and fine dust detection sensors are still used. , Wi-Fi, mobile communication repeaters, electric vehicle charging facilities, etc., there is a problem that many roadside facilities that use electricity have had to repeatedly construct power supply lines to secure their own power sources.

In addition, although these various types of roadside facilities can integrate functions such as power consumption and data transmission, as distribution line construction work is carried out independently by various entities, maintenance and management tasks are also carried out separately. There is a problem that is causing management inefficiency.

Republic of Korea Patent Publication No. 10-0808968

With reference to the accompanying drawings, embodiments of the present invention will be described in detail so that those skilled in the art can easily carry out the present invention.

The configuration of the present invention can be divided into a streetlight distribution box shown in Figure 2 and a streetlight pole system shown in Figure 3, and the present invention will be described in detail according to the attached drawings as follows.

In the present invention, as shown in Figure 2, the streetlight distribution box has a molded circuit breaker (10) disposed at the inlet, and a magnetic contact point (20 to 23) and an earth leakage circuit breaker contact point (1A to 2B) on the secondary side of the molded case circuit breaker (10). ) are connected in series,

As is known, these magnet contacts (20 to 23) wirelessly transmit a streetlight lighting signal from the control center to the CDMA built into the automatic flasher (30) of the streetlight distribution box, and the magnet contacts (20 to 23) are connected to the signal output by the CDMA. By opening and closing 23), the power supply to the streetlight is controlled through the earth leakage circuit breaker. In addition, when the selection switch 40 in the drawing shown in FIG. 2 is switched to the side indicated as a timer, the magnet contact points 20 to 23 in the drawing are turned on ( ON) to supply power, and when switched to the side described as a flasher, the magnet contacts 20 to 23 are turned on during the operation time of the automatic flasher 30, thereby turning on the power during the time required for lighting out of 24 hours. It will be supplied.

In the present invention, by selecting and operating the selection switch (40) in this streetlight distribution box, power is supplied to the streetlight pole for a time set by the digital timer (40) or power is supplied to the streetlight pole for a time controlled by the control center by the automatic flasher (30). is supplied, and the supplied power drives the driver 600 in FIG. 3 to turn on the streetlight caution LED 700,

A modem module 500 equipped with an antenna for receiving a wireless transmission signal from a control center, a control signal received by the modem module 500 is decoded by a microcontrol unit 300, and the decoded level A dimming controller 300 for driving the driver 600 with brightness and the driver 600 for lighting the LED 700 according to the dimming level signal of the dimming controller 300 are connected, and the driver 600 ) and the streetlight distribution box distribution line and power supply module 100 are connected.

In this power supply module 100, the first CT (101) and the first PT (102) used for lighting the LED (700) are connected to the driver (600) via the first terminal (112),

The second CT (110) and the second PT (111) to which the distribution line of the streetlight distribution box is connected are connected to the second terminal (122) to which a photovoltaic (PV) array is connected,

In order to supply power to roadside facilities, the 3rd CT (120) and 3rd PT (121) used for roadside facilities connected to the distribution line of the streetlight distribution box are connected to the 3rd terminal (132), thereby For nearby roadside facilities and solar cell arrays, power is supplied without separate distribution line installation work, and at the same time, the secondary side of the CT and PT (101, 102, 110, 111, 120, 121) is connected to the microcontrol unit (300). ), the voltage and current data obtained by the CT and PT (101, 102, 110, 111, 120, 121) are A/D converted by the microcontrol unit 300, and the converted Data is supplied to the modem module 500, amplified and modulated at a high frequency along with the carrier wave in the modem module 500, and then transmitted to the control center through the antenna 800.

In addition, the power supply circuit 200 supplies low direct current voltage necessary for the operation of the overall streetlight system.

The operation of the present invention as described above is explained as follows.

First, looking at the single-line diagram of FIG. 2 of the streetlight distribution box, the present invention transmits a streetlight lighting signal wirelessly to the CDMA built in the automatic flasher 30 of the streetlight distribution box from the control center when the selection switch 40 is switched to the flasher side. The signal output by CDMA opens and closes the magnet contacts (20 to 23), thereby controlling the power supply to the streetlight through the earth leakage circuit breaker.

In addition, when the selection switch 40 in the drawing shown in FIG. 2 is switched to the side indicated as a timer, the magnet contact points 20 to 23 in the drawing are turned on ( ON) and power is supplied.

In addition, these series-connected magnet contacts (20 ~ 23) and earth leakage circuit breaker (1A ~ 2B) contacts must be expanded corresponding to the number of streetlight poles to be connected.

In addition, since this present invention is based on the function of a street lamp, the location coordinates are input in consideration of the twilight time, which is later than sunset time and earlier than sunrise time, in order to turn on and off the LED 700, which is a street lamp. Ensure that lights are turned on and off in a reasonable manner according to the coordinates. In addition, the current time data is secured by a known clock basically installed in the microcontrol unit 300 of the streetlight pole system, and lighting and turning off are implemented. In this state, if the control center controls the flasher (30) or sets the magnet contacts (20 to 23) to be continuously ON by the digital timer (50), power is supplied from the distribution box 24 hours a day, which means It is supplied to the driver 600 via the first CT (101) and the first PT (102) and the first terminal (112). Meanwhile, the driver 600 waits for operation for dimming control, and the control center wirelessly transmits data specifying the dimming level, which is transmitted to the antenna 800, received and amplified by the modem module 500, and then transmitted to the microcontrol unit ( When supplied to 300), the microcontrol unit 300 decodes the corresponding data to obtain dimming level data, and applies the corresponding PWM output to the dimming controller 400 via the output port. These dimming commands are generally divided into levels 1 to 10, and are designated by the control center depending on time or region. In this way, the control output output from the dimming controller 400 is applied to the driver 600, and the driver 600 drives the LED 700 with the power of the distribution line already supplied to emit streetlight light.

At this time, the power that drives the LED 700 via the driver 600 passes through the first CT (101) and the first PT (102), so 2 of the first CT (101) and the first PT (102) The vehicle side signal is applied to the input port of the microcontrol unit 300, and the microcontrol unit 300 performs A/D conversion on the corresponding voltage and current values based on the supplied signal and converts them into digital data along with ID, which is transmitted to the modem. It is transmitted to the module 500, and the modem module 500 amplifies and modulates it and then radiates it to the antenna 800, so that the control center can calculate the power consumed by the streetlight with the current specific ID and manage the operating situation. It becomes possible. In addition, in the present invention, in order to supply power from the inverter of the solar electric array to the distribution line, the power line supplied from the streetlight distribution box passes through the second CT (110) and the second PT (111) to produce a photovoltaic (PV) array. It was connected to the inverter of the array. Accordingly, the power produced by the solar cell array is supplied to the inverter, and the inverter is connected to the second terminal 122 and supplies power to the distribution line of the streetlight distribution box through the second CT (110) and the second PT (111). Since it is applied to the input port of the microcontrol unit 300 through the secondary side of the second CT (110) and the second PT (111), the microcontrol unit 300 determines the corresponding voltage and current values based on the supplied signal. The data created through A/D conversion is converted into digital data along with the ID and transmitted to the modem module 500. The modem module 500 amplifies and modulates it and then radiates it to the antenna 800, so that the control center receives the current signal. It calculates the power produced and supplied from a solar array connected to a streetlight with a specific ID and transmits the related data to the power company so that related processes such as settlement or payment of power costs can be performed.

Therefore, the present invention can transmit the generated power simply by connecting the inverter output of the solar cell array to the second terminal 122 of the street light pole system according to the present invention without connecting it to the power line by performing separate distribution line construction. , the transmitted power amount data is transmitted to the control center, and the management center transmits it to the power management company, so that there is no need to incur additional costs for using wireless data.

In addition, in the present invention, since the streetlight distribution power line is connected to the third terminal 132 via the third CT (120) and the third PT (121), for example, an electric vehicle charger installed as a facility near the road can be installed as a standalone type. ), but in the present invention, power can be supplied to the electric vehicle charger through the third terminal 132, so power can be provided without carrying out construction for laying distribution lines.

That is, in the present invention, the power supplied from any one of the distribution lines supplied from the magnet contacts (20 to 23) and the earth leakage circuit breakers (1A, 1B, 2A, 2B) is connected to the third CT (120) and the third PT (121). It is supplied via electric vehicle charger. Accordingly, the secondary signals of the third CT (120) and the third PT (121) are applied to the input port of the microcontrol unit 300, and the microcontrol unit 300 A/D converts these input values into digital data. By converting and combining the ID data into digital data and applying it to the modem module 500, it is amplified by the modem module 500 and radiated from the antenna 800 as a high frequency output.

Accordingly, the control center considers the received voltage data, current data, and digital data synthesized with ID as the amount of power supplied to the electric vehicle charger connected to the relevant streetlight, and transmits the data to the electric vehicle charger management entity to process the necessary power. This allows follow-up processing, such as billing, to be carried out.

In addition, in reality, various data connected to terminals 1, 2, and 3 (112, 122, and 132) are transmitted as digital data along with ID. By transmitting each data in a prescribed order, the control center can accurately determine which streetlight pole is located. It is possible to identify data about the terminal.

In addition, in the present invention, the roadside facilities connected to the second and third terminals 122 and 132 are not necessarily limited to inverters or electric vehicle chargers connected to solar panel modules, and include Wi-Fi, wireless communication repeaters, and fine dust concentration sensors. , sound level meter, or CCTV. The power usage data of these facilities is also detected by CT and PT, and since the amount of data is not large during A/D conversion, data transmission is smooth using a modem module 500 such as LoRa (Long Range Wide-area network). I was able to check my luggage.

However, devices with a large amount of output data, such as CCTV, Wi-Fi, and wireless communication repeaters, must provide a separate data transmission means for data transmission, and the interface speed by LoRa (Long Range Wide-area network) is With a maximum of about 115kbps, it is possible to maintain a sufficient data transmission speed for transmitting data on the amount of power supplied and consumed by various types of roadside facilities or data acquired from various sensors.

In this way, the present invention eliminates the need to repeatedly install distribution lines for power supply in order to supply power to various types of roadside facilities, eliminating the risk of damage to the distribution lines during the process of excavation for repeated construction of distribution lines. Since there is no need to block power transmission from streetlight distribution lines even during the day, construction costs are greatly reduced by maintaining a constant power supply through distribution lines and supplying power to facilities around the road, and reducing traffic inconvenience caused by repetitive construction. All problems caused by damage to nearby tracks can be resolved.

In addition, the watt-hour meter required for each roadside facility is no longer needed, and the data transmission equipment required for each roadside facility is no longer needed, which simplifies the configuration of the roadside facilities, greatly reducing installation costs and providing modem modules for the streetlight pole system. By using (500) for public use, there is no need to pay separate data usage fees.

In addition, Figure 3 shows an example in which four streetlight pole systems connected to a streetlight distribution box can be connected.

For convenience, these are shown as the first to fourth street light pole systems (1001, 1002, 1003, and 1004), and of course they can be expanded or reduced as needed.

In addition, in the present invention, when the selection switch 40 of the distribution box is set to the flasher side, when the control center transmits power cut command data to cut off power to all roadside facilities, including street lights, the automatic flasher switches on the magnet contact point (20 ~ 23), it has the function of stopping all power supply and responding to air raids or emergency situations.

In the above, the technical idea of the present invention has been described along with the accompanying drawings, but this is an illustrative description of the best embodiment of the present invention and does not limit the present invention, and any person skilled in the art will It is a clear fact that anyone can make various modifications and imitations of dimensions, shapes, and structures without departing from the scope of the technical idea of the present invention, and such modifications and imitations are included in the scope of the technical idea of the present invention.
