Description

Technical Field

[0001] The utility model relates to the technical field of airport single-lamp monitoring, in particular to an airport navigation light status monitoring circuit and a dimmer. Background Art

[0002] Airport navigation light dimmers are the core control devices in airport navigation lighting systems, ensuring safe landings for pilots in all visibility conditions. Currently, the dimmers used in airport lighting stations are primarily sinusoidal dimmers. These dimmers utilize the high-frequency switching characteristics of insulated-gate bipolar transistors (IGBTs) and pulse-width modulation (PWM) technology to chop the grid voltage at high frequency. The IGBT's duty cycle is adjusted based on the current feedback from the circuit, achieving sinusoidal constant-current dimming. The output pulses are smooth and have minimal low-order harmonics. However, current sinusoidal dimmers on the market can only adjust the actual output current based on feedback and stabilize it at a fixed current level, without the ability to simultaneously monitor the lamp status.

[0030] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0031] The present invention provides an airport navigation light status monitoring circuit and dimmer, which detects the status of each lamp through a single lamp monitoring unit and transmits the status to the main control board through a single lamp communication control unit, so as to achieve the effect of monitoring the status of each lamp in the airport navigation light.

[0032] According to an embodiment of the present utility model, an embodiment of an airport navigation light status monitoring circuit is provided. Figure 1 FIG. 1 is a schematic diagram of a circuit for monitoring the status of an airport navigation light according to an embodiment of the present invention. Figure 1 As shown, the airport navigation light includes multiple single-lamp circuits connected in series. The airport navigation light status monitoring circuit includes: a main control board 3, a display module 4, multiple single-lamp monitoring units 1, and a single-lamp communication control unit 2.

[0033] like Figure 1 As shown, a single lamp monitoring unit 1 is connected in series with a corresponding lamp to form a single lamp circuit for monitoring the status of the corresponding lamp.

[0034] Specifically, airport navigation lights are all equipped with dimmers. The input voltage of the dimmer passes through two common-mode and differential-mode filters 6 and enters the Insulate-Gate Bipolar Transistor (IGBT) module. The IGBT module realizes sinusoidal output modulation, and then the modulated voltage is boosted by the step-up transformer 5. The waveform is then filtered by the PWM filter 6 to filter out noise and output to the lamp connection circuit of the airport navigation light.

[0035] The airport navigation light fixture connection circuit is connected in series with multiple single-lamp circuits, and a single-lamp monitoring unit 1 is connected in series in each single-lamp circuit to obtain the status of the corresponding lamp. In some optional embodiments, the status of the lamp includes: on, off, and fault.

[0036] like Figure 1 As shown, the single lamp communication control unit 2 has its input end connected to the single lamp monitoring unit 1 for obtaining the status of each lamp.

[0037] Specifically, the single lamp communication control unit 2 (SCCU) is installed on the weak current side. After each single lamp monitoring unit 1 obtains the status of each lamp, it uses power technology to feed back the lamp status information along with the current through the output cable to the single lamp communication control unit 2.

[0038] The main control board 3 has its input end connected to the output end of the single lamp communication control unit 2 and its output end connected to the input end of the display module 4 , and is used to receive the status of each lamp and send the status of each lamp to the display module 4 .

[0039] Specifically, the main control board 3 is in communication with the single-lamp communication control unit 2. The single-lamp communication control unit 2 feeds back the lamp status to the main control board 3. After receiving the status of each lamp, the main control board 3 sends the status information of each lamp to the display module 4, which displays it. Each lamp can be distinguished by setting a different ID number, and the status of different lamps is transmitted through different lines.

[0040] The display module 4 is used to receive and display the status and alarm information of each lamp respectively.

[0041] Specifically, the display module 4 is used to display information related to the dimmer and airport navigation lights, including but not limited to the status and alarm information of each lamp. The touch screen unit 42 in the display module 4 can be used to issue commands to change the status of each lamp. For example, if the touch screen unit 42 is used to change the status of a lamp from "on" to "off," the touch command is transmitted via the touch screen unit 42 to the main control board 3. The main control board 3 then transmits the command to the single-lamp communication control unit 2, which then connects the airport navigation lights to the lamp circuit. The lamp ID number determines the lamp to be turned off and controls the corresponding lamp to turn off. After the lamp is turned off, the single-lamp monitoring unit 1 then transmits the lamp status back to the main control board 3 via power carrier technology, updating the status of the corresponding lamp in the display module 4, thereby monitoring the status of each lamp in the circuit. This is for example only and is not intended to be limiting.

[0042] If a lamp fails, the single lamp monitoring module will feed back to the main control board 3. At this time, an alarm message will appear on the dimmer display screen. After seeing the alarm message, the technician will open the single lamp monitoring system interface to accurately locate the faulty lamp and repair or replace it in time.

[0043] The airport navigation light status monitoring circuit provided in this embodiment obtains the status of the lamps through the single-lamp monitoring unit 1, transmits it to the main control board 3 using the single-lamp communication control unit 2, and displays it through the display module 4, thereby realizing single-lamp monitoring of the status of each lamp in the airport navigation lights.

[0044] In some optional embodiments, such as Figure 2 As shown, the airport navigation light status monitoring circuit also includes: a transformer 5, whose low-voltage side is connected to the single-lamp communication control unit 2, and whose high-voltage side is connected to the airport navigation light, for increasing the voltage to power each lamp.

[0045] Specifically, the transformer 5 can increase the voltage of 380V to 4000V.

[0046] The airport navigation light status monitoring circuit provided in this embodiment uses a step-up transformer 5 to boost the voltage to meet the power supply requirements of the airport navigation light and ensure the normal operation of the airport navigation light.

[0047] In some optional embodiments, such as Figure 2 As shown, the airport navigation light status monitoring circuit also includes: a filter 6, whose input end is connected to the output end of the high-voltage side of the transformer 5, and whose output end is connected to the airport navigation light, for filtering clutter in the boosted voltage.

[0048] Specifically, a partition is installed in the cabinet on the high-voltage side of the dimmer, and the filter 6 is fixed on the partition and connected to the output cable of the dimmer.

[0049] The airport navigation light status monitoring circuit provided in this embodiment boosts the voltage and filters out clutter through the filter 6 before supplying power to the airport navigation light, thereby ensuring a stable voltage waveform, making the input power supply of the airport navigation light more stable, and extending the service life of the airport navigation light.

[0050] In some optional embodiments, such as Figure 2 As shown, the airport navigation light status monitoring circuit also includes:

[0051] The current transformer 7 has its input end connected to the airport navigation light and its output end connected to the input end of the high-voltage side of the transformer 5, and is used to detect the current of the airport navigation light.

[0052] Specifically, in the navigation light dimmer, the current transformer 7 detects the current in the circuit. When an open circuit, overcurrent, or short circuit occurs, it promptly triggers the protection mechanism to ensure safe operation of the device. By converting high currents into low currents, the current transformer 7 enables the instrument to safely measure high currents, preventing damage from excessive currents. The current transformer 7 also isolates the instrument from the current loop being measured, preventing potential safety hazards posed by high voltage or high current.

[0053] The airport navigation light status monitoring circuit provided in this embodiment detects the operating current level of the airport navigation light through the current transformer 7 to determine the actual brightness of the airport navigation light, making it easy to adjust the current level according to the actual brightness, thereby ensuring that the airport navigation light can provide navigation assistance under any environmental conditions.

[0054] In some optional implementations, the single-lamp communication control unit 2 is connected to the main control board 3 via a multi-pin cable, and each pin is used to transmit the status of a lamp.

[0055] Specifically, the single lamp communication control unit 2 is connected to the main control board 3 through a multi-pin cable. One pin of the cable is used to transmit the status of a lamp. The number of pins of the cable should not be less than the number of lamps in the airport navigation light.

[0056] In the airport navigation light status monitoring circuit provided in this embodiment, the single-light communication control unit 2 is connected to the main control board 3 via a multi-pin cable, and signal transmission is stable and space-saving.

[0057] In some optional embodiments, such as Figure 2 As shown, the display module 4 includes: a display unit 41 and a touch screen unit 42, wherein,

[0058] The display unit 41 is used to display the status and alarm information of each lamp.

[0059] The touch screen unit 42 is used to receive touch instructions, generate touch responses and transmit them to the main control board 3.

[0060] Specifically, the display module 4 mainly includes two functions: display and touch screen, which are implemented by the display unit 41 and the touch screen unit 42 respectively. The display content and touch screen instructions can be set according to actual conditions. The specific implementation process is an existing mature technology and will not be repeated here.

[0061] The airport navigation light status monitoring circuit provided in this embodiment displays the status and alarm information of each lamp through the display unit 41, which is conducive to determining the cause of the fault based on the alarm information. The touch screen unit 42 can be used to control the status of the lamp or adjust the settings of the airport navigation light.

[0062] In this embodiment, a dimmer is also provided. Figure 3 As shown, the dimmer includes the airport navigation light status monitoring circuit of any one of the previous embodiments.

[0063] Specifically, this embodiment integrates a single-lamp monitoring unit 1 and a single-lamp communication control unit 2 into the dimmer. Lamp status information is fed back to the dimmer via the dimmer's main control board 3, enabling status and alarm information to be displayed on the dimmer screen. This adds single-lamp monitoring functionality to the dimmer's existing dimming function, simplifying the wiring circuit.

[0064] The dimmer provided in this embodiment integrates a single lamp monitoring function, simplifies the connection circuit, optimizes the dimmer function, and saves airport operation and maintenance costs.

[0065] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
