Description

TECHNICAL FIELD

[0001] The utility model relates to navigation light technical field especially relates to a LED navigation light state monitoring system. BACKGROUND

[0002] International Regulations for Preventing Collisions at Sea (COLREG) stipulates that the ship should turn on the number light (navigation light) at night or low visibility, and the setting position, color and light angle of the light, especially the visible distance have strict requirements.

[0003] Previously, the navigation light takes incandescent lamp as light source, and the incandescent lamp is generally invalid only after the filament is fused, so that the navigation light controller (NLC) on the ship can monitor whether the navigation light is invalid through the on-off of the incandescent lamp, and then remind the driver to switch the standby navigation light or replace the light source in time.

[0004] In recent years, due to the need of energy saving, the light source of the navigation light is mostly replaced by LED lamp bead instead of the original incandescent lamp, and the energy consumption of the light source of the navigation light is greatly reduced from about 60W to about 6W. But the LED lamp bead has the light decay characteristic of light emission, and the light intensity will gradually weaken after a period of use, until the light intensity cannot meet the requirements of the visible distance of the International Regulations for Preventing Collisions at Sea (COLREG), and at this time the LED lamp bead is still conducting, which leads to that the traditional navigation light controller (NLC) cannot accurately monitor the state of the LED lamp bead, and then cannot remind the driver to switch the standby navigation light or replace the light source in time, so that the ship faces huge safety hazards.

[0005] Therefore, under the International Maritime Organization (IMO), the resolution MSC.253 (83) of the Maritime Safety Committee (MSC) requires that when the light intensity of the LED lamp bead is insufficient, the alarm function should be started to inform the duty driver; or the LED lamp bead maintains the necessary light intensity within the service life stipulated by the manufacturer.

[0006] At present, in order to enable the navigation light controller (NLC) to effectively monitor the navigation light with LED lamp beads as the light source, most navigation light controller manufacturers adopt the timer to calculate the service life of the LED lamp beads, and take the service life as the basis for the pilot to switch / replace the navigation light, for example: the working life of the LED lamp bead is marked as 5000h (more than one year), and the navigation light needs to be replaced after the timer counts to 5000h, so as to ensure the safety of the ship. However, the light intensity attenuation of the LED lamp bead is affected by multiple factors such as heat dissipation, voltage and current, and chip quality, so that the life record of the timer cannot well correspond to the actual light intensity of the LED lamp bead, that is, the light intensity of the LED lamp bead may not meet the requirements while the life record has not reached the service life of the LED lamp bead, which leads to a great risk of the ship; or the light intensity of the LED lamp bead still meets the requirements, but the life record has reached the service life of the LED lamp bead, which leads to waste.

[0037] In addition, in the description of the present application, unless otherwise specified, the meaning of "multiple" is two or more.

[0038] Referring to Figure 1 and Figure 2 , the embodiment provides an LED navigation light state monitoring system, which comprises an LED navigation light 1 and a navigation light controller 2. The LED navigation light 1 comprises an LED body 101, a light intensity detection module 102 and a lamp shell 103. The LED body 101 and the light intensity detection module 102 are arranged in the lamp shell 103. The light emitted by the LED body 101 can pass through the lamp shell 103 to illuminate the outside. The light intensity detection module 102 is located in the illumination range of the LED body 101. The navigation light controller 2 supplies power to the LED body 101 and is signal connected with the light intensity detection module 102.

[0039] The LED navigation light state monitoring system of the embodiment can detect the light intensity of the LED body 101 through the light intensity detection module 102, and the detection result of the light intensity detection module 102 can be directly transmitted to the navigation light controller 2. The navigation light controller 2 can monitor the light intensity of the LED body 101 in real time. When the program judges that the light intensity of the LED body 101 does not meet the requirements of the international maritime collision regulations (COLREG) on the visible distance, the navigation light controller 2 will timely alarm to remind the driver to switch or replace the light source.

[0040] Obviously, the LED navigation light state monitoring system of the embodiment can accurately determine whether the LED navigation light 1 needs to be replaced, thereby ensuring the safety of the ship at sea.

[0041] Preferably, the light intensity detection module 102 is a photoresistor or a light intensity sensor.

[0042] Preferably, in the embodiment, the light intensity detection module 102 preferably adopts a light intensity sensor.

[0043] Although both the photoresistor and the light intensity sensor can be used to detect the light intensity, since the LED navigation light is basically located at the highest position of the ship in actual use, it is easily affected by vibration and shaking, causing fluctuations in the detection data and leading to inaccurate monitoring results. In addition, the photoresistor has slow response speed, low sensitivity, high self-consumption, poor linearity, short service life, and is sensitive to temperature, so it is not the best choice for real-time monitoring of light intensity.

[0044] Specifically, in the embodiment, the light intensity sensor used has a power supply voltage of 3.3V-5V and a working current of tens of μΑ, and has very small self-consumption.

[0045] Preferably, referring to Figure 1 , the LED body 101 is a columnar structure vertically arranged on the lamp holder 104 at the bottom of the lamp shell 103. A plurality of LED lamp plates 105 are arranged on the LED body 101 in a ring shape at intervals around the axis of the LED body 101. The light intensity detection module 102 is arranged away from the LED body 101. A plurality of light intensity detection modules 102 are arranged on the lamp holder 104 at the bottom of the lamp shell 103 in a ring shape at intervals around the axis of the LED body 101, and each light intensity detection module 102 is arranged to directly face one LED lamp plate 105.

[0046] The plurality of light intensity detection modules 102 and the plurality of LED lamp plates 105 maintain a one-to-one correspondence, and the distribution angle between the directly facing light intensity detection module 102 and the LED lamp plate 105 is a right angle, thereby helping to ensure that each light intensity detection module 102 detects the light intensity of the LED lamp plate 105 at the same position, making the detection result more accurate.

[0047] Preferably, in the embodiment, the light intensity detection module 102 is connected and fixed to the lamp holder 104 by bolts.

[0048] Preferably, referring to Figure 2 , the navigation light controller 2 comprises an I2C controller 201, the I2C controller 201 has an alarm function, and the plurality of light intensity detection modules 102 are signal connected to the I2C controller 201.

[0049] When the light decay of a certain LED lamp panel 105 does not meet the requirements or does not work, the I2C controller 201 inside the navigation light controller 2 can monitor it in real time through the signal of the corresponding light intensity detection module 102, and then issue an alarm to remind the driver to switch or replace the light source.

[0050] Preferably, referring to Figure 2 , the plurality of light intensity detection modules 102 are signal connected to the I2C controller 201 through an I2C bus, so as to simplify the wiring through the I2C bus.

[0051] Preferably, referring to Figure 2 , the navigation light controller 2 further comprises a luminous intensity display 202, and the luminous intensity display 202 is signal connected to the I2C controller 201.

[0052] It should be noted that the luminous intensity display 202 can display the luminous intensity value measured by a light intensity detection module 102 every interval, and after displaying the measured values of all light intensity detection modules 102 in turn, it will be displayed again.

[0053] Therefore, if the measured value of a certain light intensity detection module 102 is not displayed, it means that the light intensity detection module 102 has failed, so that the working state of each light intensity detection module 102 can be monitored through the luminous intensity display 202, which is convenient for personnel maintenance.

[0054] Preferably, referring to Figure 2 , the navigation light controller 2 further comprises an interrupt controller 203, and the interrupt controller 203 is signal connected to the I2C controller 201.

[0055] It should be noted that the interrupt controller 203 can control the shutdown or switching of all LED lamp panels 105, and therefore, when a certain LED lamp panel 105 fails, the power supply of the LED lamp panel 105 can be turned off through the interrupt controller 203, and only the LED lamp panel 105 needs to be replaced, which not only avoids unnecessary waste, but also does not affect the normal work of other LED lamp panels 105, ensuring the safety of the ship at sea.

[0056] Preferably, in the embodiment, the interrupt controller 203 can adopt physical control or logical signal control to realize the turn-off or switching of all LED lamp panels 105.

[0057] Preferably, referring to Figure 2 , the navigation light controller 2 further comprises a timing counter 204 which is in signal connection with the I2C controller 201.

[0058] Thanks to the existence of the light intensity detection module 102, the LED navigation light state monitoring system of the embodiment does not need to distinguish the state of the LED navigation light 1 through the timing counter 204, and therefore the timing counter 204 in the embodiment is used to calculate the quality of the LED lamp panel 105.

[0059] In summary, the LED navigation light state monitoring system of the embodiment does not change the structure of the LED navigation light which is currently used by most of the timers, and only the light intensity detection module 102 is sleeved on the bottom of the current LED light source, thereby avoiding the secondary waste caused by the large-scale update of the lamps; in addition, the light intensity detection module 102 in the embodiment preferably adopts a light intensity sensor, thereby having the characteristics of long service life and modularity.

[0060] The above description is only the preferred embodiment of the utility model, and it should be pointed out that for the ordinary skilled in the art, without departing from the technical principles of the utility model, a number of improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection range of the utility model.
