Low intensity aviation obstruction lighting is specialized lighting designed to increase visibility of obstacles and dangerous structures which pose a risk to passing aircraft. These lights are designed to locate the obstacle quickly and accurately to provide maximum safety for passing aircraft and people on the ground. In addition, the low intensity lights can also be used to highlight a runway or a path to an airport.

The low intensity aviation obstruction lighting system consists of a power source, a controller, and lighting fixtures. The power source is typically a generator or a solar panel. The controller, or automated system, sends signals to the power source to activate or deactivate the lights. The lighting fixtures are specially designed to provide a consistent output of light over long distances. They are typically red and white in color, though green and amber variations are also available.

Low intensity aviation obstruction lighting has many benefits, including the ability to save energy, reduce maintenance costs, and provide enhanced visibility. The improved visibility helps ensure that aircraft remain safe and that any obstacles that pose risks to aircraft are readily visible. In addition, these lights require minimal maintenance, making them a cost-effective solution for airports and other structures subject to aviation regulations.

The low intensity aviation obstruction lighting market is expected to witness steady growth in the coming years. This growth is driven by increased safety requirements, increased demand for energy efficient solutions, and advancements in technology. Low intensity lights provide airports with the opportunity to meet safety requirements while also saving energy costs. Additionally, airports and other structures are expected to benefit from new technologies, such as moving and flashing lights, which provide greater visibility over longer distances.

As aviation and airports continue to grow, the demand for low intensity aviation obstruction lighting is expected to increase. This growth is expected to drive innovation, further improving the efficiency and reliability of these lights. As the industry progresses, we can expect to see even more efficient and reliable solutions, making the low intensity aviation obstruction lighting sector a strong market for the future.

2. How to solve the interference problem of aviation obstruction light monitoring system?

1. Interference in the installation place of the obstruction light

First of all, due to the definition of its own existence, obstruction lights are used in environments with high-rise structures such as thermal power plants, chemical plants, radio and television towers, communication towers, airports, etc. The special features of this kind of external environment are that the coexisting equipment is complicated. , The electromagnetic interference is serious, and the on-site collection end of the fn fault monitoring system will inevitably be affected by the distributed interference in these large environments. Secondly, the front-end machine and communication management machine of the monitoring system are installed next to the ten obstruction light equipment, and the equipment is used for power supply, and collection and transmission of equipment signals. Therefore, it is necessary to guard against interference problems caused by the equipment under test. Furthermore, local spontaneous interference will also be generated inside the front-end machine and the communication management machine, so while resisting the interference outside the system, it is also necessary to control the mutual influence between internal devices and circuits. These are all problems that need to be studied and resolved.

 2. External environmental factors where the obstruction light monitoring system is located

The external environment of the obstruction light monitoring system includes natural problems such as lightning strikes and electromagnetic radiation in space, but also electromagnetic interference caused by high voltage, high frequency, and engines caused by artificial factors. For example, there are high-voltage interference signals of 50Hz power frequency cycle and N-order harmonics around power plants and high-voltage transmission towers, and electrical appliances in the power supply grid can also cause operating overvoltages. The typical environment of radio, television tower, and communication tower is the high-power, high-frequency, and radio frequency interference of the antenna at the top of the ten transmission tower.

3, the signal interference of the obstruction light system itself

The obstruction light system, which is the monitoring object of the monitoring system, is also a source of interference, from lamps, connecting cables to the control box will release varying degrees of interference. Automatic bulb-changing obstruction lights generally use relays to drive the lamp to switch. These devices will produce pulse interference, especially high-intensity obstruction lights generally use nitrogen discharge light source, the internal trigger pulse signal is generated by the thyristor device, and a control box is required to generate it. External trigger pulse signal, this control method will cause instantaneous discharge pulse interference, which directly causes electromagnetic interference in the entire path from the control box that generates the pulse signal, the cable that transmits the pulse signal to the lamp terminal that uses the pulse signal, the power line and the control line There are a large number of distributed capacitances. In this regard, the obstruction light system adopts measures such as power filter cable multi-core shielding and grounding to suppress and protect, and try to install the high-intensity control box near ten high-intensity lamps to shorten the interference propagation path.

4. The interference problem of the obstruction light system's acquisition end

The front-end machine in the collection end of the monitoring system is installed near the device under test, and at the same time, it is responsible for the task of directly interacting with the monitored object's circuit signals, so it is the focus of the field collection end to solve the interference problem. It can be seen from the composition and connection of the front-end machine that the power supply part and the signal detection circuit directly connected to the interference source of the obstruction light are the links that need to be paid attention to. In addition, the input and output interfaces, communication cables, PCB board units, etc. are also vulnerable The weak part of the disturbance. Although the GPRS module used in the communication management machine is a radio frequency transceiver unit, it is a mature industrial product and EMC is still good, so there is no need to study too much, and more attention can be paid to the vulnerable parts similar to the front-end machine.

3. Standard

The aviation obstruction light design specifications are not arbitrarily set up or not set, but are designed according to the design specifications of the Chinese civil aviation standard aviation obstruction lights. Below, the editor will elaborate for you one by one.

1. Fixed obstacles within 3000m from the inner edge of the take-off climbing surface and protruding above the surface should be marked; if the runway is used at night, it should also be illuminated.

2. Objects adjacent to the take-off climbing surface, although they have not yet constituted an obstacle, should be marked if it is deemed necessary to ensure that the aircraft can avoid it; if the runway is for night use, it should also be illuminated.

3. The fixed obstacles protruding from the inner edge of the approach surface within 3000M, or the inner transition surface, should be marked; if the runway is used at night, it should also be illuminated.

4. Fixed obstacles protruding above the water level must be marked; if the runway is for night use, it should also be illuminated.

5. Fixed objects protruding above the protective surface of obstacles should be marked; if the runway is for night use, it must also be illuminated.

6. In the aircraft movement area, all vehicles and moving objects are obstacles outside the aircraft and must be marked. If used at night or under low visibility conditions, they must also be illuminated. Only aircraft that are used only on the apron Maintenance equipment and vehicles can be exceptions.

7. The vertical aviation ground lights in the aircraft activity area must be marked to make them distinct and eye-catching during the day, but no obstruction lights shall be set on the vertical lights and signs.

8. All obstacles within the specified small distance from the taxiway, apron taxiway or the center line of the aircraft taxiway must be marked. If these taxiways or taxiways are used at night, they must also be illuminated. .

9. In areas outside the restricted area of obstacles, obstacles with a height greater than 150M above the surrounding ground should be marked and illuminated if they are deemed to have constituted a hazard to the aircraft through special navigation studies. However, if the obstacle is equipped with For high-intensity obstruction lights that operate during the day, the signs can be omitted.

10. Overhead wires or cables across rivers, valleys or highways, etc., if it is considered by navigation studies that these wires or cables may constitute a hazard to the aircraft, they shall be marked and their supporting towers shall be marked and illuminated. There are high-intensity obstruction lights that operate during the day, so the sign can be omitted.

11. When it has been determined that it is impractical to install markers on overhead wires or cables that should be marked, B-type high-intensity aviation obstruction lights that operate during the day should be installed on the supporting poles.

After reading these 11 Chinese civil aviation obstruction lights design specifications, do you feel that your head is a bit big? In fact, the trick to remember is that as long as the height exceeds 45 meters, whether it is a natural obstacle or a man-made building, it must be marked with aviation obstruction lights. Different types of aviation obstruction lights are set according to the different heights of actual obstacles, because different obstruction lights are set at different heights, and there are strict standards and specifications.

Background knowledge:

Military executive standards for aviation obstruction lights

Aviation obstruction lights are one of airport navigation aid lamps, which are subordinate to special airport navigation aid lamps. It is mainly installed on obstacles and is not suitable for installation on airport runways and airport taxiways. Instead, they are installed on airport towers and obstacles surrounding the airport that are higher than the surrounding ground. The choice of aviation obstruction lights is based on the height of the obstacle.

The standards for aviation obstruction lights implemented by civil airfields and military airfields are somewhat different. The aviation obstruction light standards implemented by military airports are more stringent than those of civil general aviation airports. The aviation obstruction lights implemented by military airports must meet the national standards and industry standards required by the country for aviation obstruction lights, such as "Aviation Obstruction Lights" (MH/T6012-2015) and "Aviation Obstruction Lights Inspection Specifications" (AC-137 -CA-2017-05), and then meet the standard requirements of military airports for aviation obstruction lights.

According to the current standard requirements for aviation obstruction lights for military airports, there are mainly the following two standard specifications:

   1. The notice of the State Council and the Central Military Commission on the issuance of the "Regulations on Clearance of Military Airports";

   2. Chinese People's Liberation Army Engineering Construction Industry Standard "Technical Specification for Obstacle Marking in Clearance Area of Military Airport"

The current military airport aviation obstruction light setting reference standard specifications are mainly implemented in accordance with the above-mentioned standard specifications. The selection of aviation obstruction lights must be implemented in accordance with the above-mentioned standards. It is no longer implemented in accordance with the civil airport standards for aviation obstruction lights.

The standards implemented by military airports will not cause changes in the basic technical parameters of aviation obstruction lights, and will not cause any impact on the aviation obstruction lights produced by aviation obstruction light manufacturers. The premise is that the aviation obstruction light manufacturers produced meet the latest aviation obstruction light industry standards and specifications. The only influential is the design unit. For example, when the design institute considers the selection of aviation obstruction lights, the aviation obstruction lights selected according to the civil aviation obstruction light standard and the military aviation obstruction light standard are not the same style. Therefore, you need to pay attention when designing. The others are not much different.
