Description

[Technical Field]

[0001] The present invention relates to a remote automatic on / off system for lighting fixtures installed on utility poles, lighting poles, steel towers, etc. [Background technology]

[0002] Conventionally, there is a system in which a wireless module is built into a lighting fixture, and the wireless module equipped with an illuminance sensor controls the flashing at sunrise and sunset instead of the existing automatic flashing switch.

[0003] For example, as disclosed in Patent Document 1, there is an automatic on / off control device that automatically turns on and off a lighting fixture installed in a building only in response to changes in the brightness of the location where the lighting fixture is installed. That is, this technology is composed of a photoelectric conversion element having at least a part of the same detection field of natural light and the illumination field of the lighting fixture, a first comparison circuit that generates a turn-on signal when the output level output from the photoelectric conversion element falls below a set lighting start level, a memory circuit that stores data on the output level output from the photoelectric conversion element after the lighting fixture is turned on, and a second comparison circuit that compares the post-lighting level stored in this memory circuit with the output level output from the photoelectric conversion element, and generates a turn-off signal when the output level output from the photoelectric conversion element rises above the stored post-lighting level.

[0004] [Patent Document 1] Republished Patent No. WO2010 / 150701 Summary of the Invention [Problem to be solved by the invention]

[0005] However, conventionally, lights were turned on and off by detecting sunlight using a light sensor, and because they used AC power, problems such as lightning strikes were common.

[0006] Furthermore, in the case of the aforementioned Patent Document 1, when solar cells are used and attached to the outside of a housing, through holes are always required to connect to the inside, which increases the risk of breakdown due to rainwater entering and increases costs due to the complicated structure. In addition, the surface of the solar cells may be deteriorated by wind, rain, and ultraviolet rays.

[0007] Therefore, the present invention was created in consideration of the various circumstances that existed in the past as described above, and aims to provide a remote automatic flashing system for street lights, etc., which can be retrofitted to existing lighting fixtures, does not use AC power sources, but uses solar cells, capacitors (storage batteries), and latching relays, thereby eliminating problems caused by induced lightning strikes and other lightning-induced failures, is maintenance-free, and consumes little power. [Means for solving the problem]

[0008] Specifically, the housing is partially made of transparent plastic, and a solar-powered wireless module is mounted inside the housing for charging. The solar cells are assumed to be amorphous or dye-sensitized batteries, which generate electricity even under weak light. The storage battery will be a supercapacitor or lithium-ion capacitor, which is resistant to high-temperature environments and has a long lifespan, making it maintenance-free and eliminating the need for replacement. While the capacitor has a smaller capacity than a lithium-ion storage battery, it will operate on less power by using a low-power wireless module and a latching relay (a mechanical relay latched with a one-shot pulse). Furthermore, while existing automatic flashers use semiconductor non-contact relays such as triacs, which are prone to induced lightning failures, this invention uses a mechanical relay with contacts, improving insulation.

[0009] In order to solve the above-mentioned problems, in the remote automatic lighting system according to the present invention, an IoT gateway having a wireless function connected to a remote data center server by a communication line and a wireless module of a data center-linked wireless automatic lighting switch are configured to be able to wirelessly communicate with each other, and the data center-linked wireless automatic lighting switch is equipped with a solar cell and a capacitor that charges power from the solar cell via a DCDC converter together with the wireless module, and the wireless module has an ON-OFF switching means that sends a set pulse and a reset pulse to a latching relay connected to a lighting fixture in response to a blinking command from the IoT gateway connected to the data center server, and controls the turning on / off of the lighting fixture using the power supplied by the solar cell of the capacitor, The ON-OFF switching means is provided so that a receiving module mounted on the lighting fixture and a wireless transmitting module mounted on a housing of a solar cell installed near the lighting fixture can communicate with each other. 、 The ON-OFF switching means enables a signal for controlling the turning on / off of the lighting fixture to be transmitted as radio waves from the wireless transmitting module in the solar cell housing to the receiving module in the lighting fixture only when there is a change in sunrise / sunset due to the power charged by the capacitor in the solar cell. It is characterized by the following.

[0010] The solar cell may be attached to the back side of a transparent cover that closes the cover housing and sealed therein. [Effects of the Invention]

[0013] According to the present invention, by using a solar cell, a capacitor (electric storage), and a latching relay instead of an AC power source, troubles caused by induced lightning strikes and other lightning-induced failures can be eliminated, and a remote automatic flashing system for street lights, etc. can be provided that is maintenance-free and consumes little power, thereby improving the efficiency of wiring work.

[0014] In other words, the remote automatic lightening system of the present invention is configured to enable wireless communication between an IoT gateway with wireless capabilities installed in a lighting fixture connected to a remote data center server by a communication line, and a wireless module of a data center-linked wireless automatic lightening switch installed in the lighting fixture, and the data center-linked wireless automatic lightening switch is equipped with a solar cell and a capacitor that charges power from the solar cell via a DCDC converter along with the wireless module, and the wireless module has an ON-OFF switching means that sends set pulses and reset pulses to a latching relay connected to the lighting fixture in response to a blinking command from the IoT gateway connected to the data center server, and controls the turning on / off of the lighting fixture using the power supplied by the solar cell of the capacitor, so that by using a solar cell, a capacitor (storage battery), and a latching relay, problems caused by induced lightning failures such as lightning strikes are eliminated, and compatibility is ensured by using a DCDC converter with a wide input range.

[0015] The solar cell is attached to the back of the transparent cover that closes the cover housing and is enclosed within, so the transparent cover allows charging inside the plastic box, eliminating the need for the conventional through-holes, reducing the risk of water intrusion, and also making it possible to use non-waterproof solar cells.

[0016] Furthermore, the ON-OFF switching means is arranged to enable communication between an electric lighting fixture equipped with a receiving module and a wireless transmitting module mounted on a solar cell housing installed near the lighting fixture, and allows the power charged by the solar cell's capacitor to be transmitted as radio waves from the wireless module in the solar cell housing to the lighting fixture's receiving module only when there is a change in sunrise / sunset, so no AC power supply is used, there is no risk of induced lightning failure, wiring work is not required, and costs can be reduced.The use of a capacitor eliminates the need for battery replacement, and as long as the radio wave reach is within range, there is no need to install multiple modules like an automatic flasher, and multiple lights can be controlled with a single module, making it low cost.

[0017] The solar cell housing is equipped with a tip-over sensor that transmits radio waves only when there is a change in the state of tipping, making it possible to communicate even when buried in sand. In addition, the tip-over sensor due to landslides is separated from the AC line, eliminating the risk of wiring interruption or damage caused by induced lightning. [Brief explanation of the drawings]

[0018] [Figure 1] 1 is a perspective view of a remote automatic flashing system according to one embodiment of the present invention; [Figure 2] FIG. 10 is a perspective view of the solar cell built-in wireless module in an assembled state. [Figure 3] FIG. 10 is a perspective view showing an example of use of a wireless transmission module according to another example of the present embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0019] In the present invention, while it is normally necessary to constantly flow current through the relay coil, a latching relay only requires current in the form of a set pulse and a reset pulse, making it possible to drive it with a capacitor having a small capacity storage battery.

[0020] In other words, the existing metal lighting fixtures (which cannot be equipped with wireless modules) are left as they are, and the existing automatic flashers are replaced with wireless automatic flashers equipped with latching relays. Furthermore, no illuminance sensors are installed, and flashing commands are sent wirelessly to multiple wireless automatic flashers from a master unit (microcomputer + wireless module) connected to a data center server. This creates a data center-linked wireless automatic flasher (IoT) that communicates with the data center server and can arbitrarily control the lights to turn on and off according to commands from the data center server, even without an illuminance sensor.

[0021] An embodiment of the present invention will be described in detail below with reference to the drawings. Figures 1 and 2 show a remote automatic lighting system according to this embodiment. This system is configured to enable wireless communication between an IoT gateway 2 with wireless capabilities, in which lighting fixtures P are installed, and which is connected to a data center server 1 in a remote location via a communication line, and a wireless module 4 with a wire antenna 4A of a data center-linked wireless automatic lighting switch 3 in which the lighting fixtures P are installed. A lighting command signal from the IoT gateway 2 connected to the data center server 1 is received by the wireless module 4.

[0022] The solar cell 5 is enclosed in a cover housing 6 (see Figure 2). That is, the solar cell 5 is attached to the back side of a transparent cover 7, and the transparent cover 7 is fixed to the cover housing 6 equipped with the data center-linked wireless automatic flasher 3 with the wireless module 4 built in, by hooks 8 at four locations on the left and right.

[0023] The data center-linked wireless automatic flasher 3 comprises a capacitor 10 that charges with power from a solar cell 5 via a DCDC converter 9, a wireless module 4 that is connected to the capacitor 10 via a first diode 11 and to a lithium coin battery 13 via a second diode 12, and a latching relay 15 that is turned on / off by sending set pulses and reset pulses from the wireless module 4 via NMOS transistors 14A and 14B for current amplification. The wireless module 4 has an ON-OFF switching means Q that sends set pulses and reset pulses to the latching relay 15 connected to a lighting fixture P in response to a flash command from an IoT gateway 2 connected to the data center server 1, and arbitrarily controls the on / off switching of the lighting fixture P by an AC power source 16 that supplies power to the lighting fixture P.

[0024] Next, an example of use of the configuration configured as above will be described. First, a set pulse is given to ON-OFF switching means Q by power charged from solar cell 5 to capacitor 10 by sunlight, turning it into the ON state, and lighting fixture P is lit by AC power supply 16. At this time, a blink command signal from IoT gateway 2 connected to data center server 1 is received by wireless module 4. That is, a blink command is wirelessly transmitted from a parent device (microcomputer + wireless module) connected to data center server 1 to multiple data center-linked wireless automatic flashers 3 equipped with latching relays 15, and a set pulse is sent from wireless module 4 on the data center-linked wireless automatic flasher 3 side to latching relay 15, turning it into the ON state, and lighting fixture P is lit by AC power supply 16.

[0025] If it is assumed that an induced lightning fault such as a lightning strike will occur, a flashing command is wirelessly transmitted from the parent device (microcomputer + wireless module) connected to the data center server 1, and the ON-OFF switching means Q sends a reset pulse to the latching relay 15 from the wireless module 4 on the data center-linked wireless automatic flasher 3 side, turning it off, and the lighting fixture P cuts off the path to the AC power source 16 and turns off. In this way, by communicating with the data center server 1, lighting fixture P can be arbitrarily controlled to turn on and off by commands from the data center server 1, even without an illuminance sensor.

[0026] 3 shows an example of use of a wireless transmission module in another example of this embodiment, in which a lighting fixture P made of electric lighting equipment equipped with a receiving module 25 is communicably connected to a wireless transmission module 22 mounted on a housing 24 of a solar cell 5 installed near the lighting fixture P. This lighting fixture P is equipped with a camera linkage function and an email notification function (not shown).

[0027] The ON-OFF switching means transmits the power from the lithium ion capacitor 21 charged by the solar cell 5 as radio waves from the wireless transmission module 22 in the housing 24 of the solar cell 5 to the receiving module 25 of the lighting fixture P only when there is a change in sunrise / sunset, thereby enabling the ON-OFF switching means Q to switch the lighting fixture P on and off.

[0028] This eliminates the need for AC power, eliminates lightning-induced failures, and eliminates the need for wiring work, reducing costs. By using lithium-ion capacitors 21, battery replacement is no longer necessary, and as long as the light is within the reach of radio waves, there is no need to install multiple units like automatic flashers; multiple lights can be controlled with one module, reducing costs.

[0029] The housing of the solar cell 5 is equipped with a tip-over sensor 23, and only when there is a change in the state of tipping over does the wireless transmission module 22 transmit radio waves to the receiving modules 25 of the multiple lighting fixtures P. This makes it possible to communicate even when the lighting fixture is buried in earth and sand, and since the tip-over sensor 23 due to a landslide is separated from the AC line, there is no need to worry about wiring breakage or induced lightning failure. [Industrial Applicability]

[0030] In addition to lighting fixtures P, the remote automatic flashing system of the present invention may also be used for various other purposes, such as electrically connecting multiple electronic devices, or between a specific electronic device and an information input / output device, a driving source, an alarm device, etc. [Explanation of symbols]
