Description
Technical Field
The application belongs to the technical field of navigation light control schemes, and particularly relates to a navigation light intensity output level configuration switching system and a switching method thereof.
Background
In the traditional navigation aid lamp, the light intensity of the central line lamp of the sliding road is determined, namely, the central line straight line section of the sliding road, the average light intensity of the main light beam is more than 200cd, the central line curve section of the sliding road, and the average light intensity of the main light beam is more than 100 cd. However, as more and more airports employ advanced ground guidance systems such as a-SMGCS, the light intensity requirements of the taxiway centerline light are different, such as in ICAO-accessory 14, which clearly suggests a high light intensity taxiway centerline light intensity map where advanced ground activity guidance straight and curved sections of higher light intensity exist. From the standpoint of airport use and installation embodiment feedback, it is desirable to increase the light intensity in the feedback taxiway where the light intensity is insufficient in some areas. Therefore, it is necessary to integrate some landslide lamps with different light intensity configuration requirements into the same set of lamps, and reduce or increase the light intensity output according to the actual use requirements on site.
When in actual use, the output (light intensity/illumination level) of the navigation light is matched with the magnitude of the input current, and is limited by a power supply system and a control mode, the output of the general dimmer is a fixed number of specific values and is divided into a plurality of levels from low to high according to the magnitude of the input navigation light current, and is a five-level dimming system, namely, the power supply input current is one level, the navigation light is output with one level of light intensity, the input current is two levels, and is output with two levels of light intensity, and the like, and for any navigation light, when the dimmers or the power supplies of the same or the same series are connected, the input current of the same level is the same, and the dimmer or the power supplies are converted into different output light intensities only through a control circuit solidified in the navigation light; according to the requirements of the production and use specifications of the navigation lights, the navigation lights used in different positions have corresponding requirements on the minimum and maximum illumination when the navigation lights work normally, so that the general navigation lights are all subjected to five-level dimming.
From the angles of lamp design and light intensity requirements, lamps with different light intensity configuration requirements can be unified into a set of optical and structural components, and when higher light intensity configuration can be covered, low light intensity only needs to adjust and drive current output to the LED lamp beads. However, in practice, since the lamp has only a cable end of 2PI N, and has no external communication capability, the lamp is often required to be disassembled for replacement configuration, adjustment is performed on the circuit board, the process is too complicated, and for the lamp already installed on the road surface, adjustment is less likely to be performed.

Based on the foregoing basic contents and steps, the following description is made in connection with specific examples:
The different level outputs of the dimmer are identifiable in hardware and transferred to software in real time, and the dimmer generally works for a period of time after the level is adjusted in the actual use process according to the use standard and specification requirements, and only when the airport visibility is changed, the dimmer can perform one-time adjustment, and the light level is increased or reduced. Even in dimmer use at off-airport sites, such as test links, few situations are encountered in which it is desirable to continuously adjust the dimmer output light level multiple times.
Therefore, the constant current light modulator can regularly perform light level switching for a plurality of times in a limited time, so that the differentiated detection of the constant current light modulator and the common power supply current can be realized, the switching of different configurations can be realized, and the memory can be stored in the lamp.
Here we use a continuous mobilization for a short time (e.g. mobilization within 5 seconds) and a continuous, specified input current level mobilization procedure (e.g. 6 mobilizations, in turn 1-5-4-2-1-4, i.e. configuration identification sequences) to confirm the intention of the dimmer operator to switch light levels, enabling the adjustment of the three output configurations in table 1 in the same navigational light.
The specific process is as follows:

When the current input current level (dimmer output level) is not 1 level, outputting corresponding light intensity level according to the current configuration under the current configuration of the navigation lamp according to the current input current level;
When the input current level is 1 level, software starts to judge in real time, and outputs the 1 level light intensity according to the current configuration, and waits for the data of the next input current level;
State 2:

if the next input current level is 5 levels within 5 seconds, outputting 5 levels of light intensity according to the current configuration, and entering a state 3;
State 3:
If the input current level does not change within 5 seconds or the next input current level is not 4 levels, the output of the corresponding light intensity level is carried out according to the current configuration without processing, and the state 1 is returned;
if the next input current level is 4 levels within 5 seconds, 4 levels of light intensity are output according to the current configuration; enter state 4;
state 4:
the software restarts timing and waits for the data of the next input current level;
if the input current level does not change within 5 seconds or the next input current level is received and is not 2 levels, the input current level is not processed, the output of the corresponding light intensity level is carried out according to the current configuration, and the state 1 is returned;
If the next input current level is 2 levels within 5 seconds, 2 levels of light intensity are output according to the current configuration, and the state 5 is entered;
state 5:
the software restarts timing and waits for the data of the next input current level;
if the input current level does not change within 5 seconds or the next input current level is received and is not 1 level, the input current level is not processed, the output of the corresponding light intensity level is carried out according to the current configuration, and the state 1 is returned;
if the next input current level is 1 level within 5 seconds, 1 level light intensity is output according to the current configuration, and the state 6 is entered;
State 6:
the software restarts timing and waits for the data of the next input current level;
if the input current level does not change within 5 seconds or the next input current level is received and is not the level 4, the output of the corresponding light intensity level is carried out according to the current configuration and the state 1 is returned;
if the next input current level is 4 levels within 5 seconds, 4 levels of light intensity are output according to the current configuration, and the state 7 is entered.
State 7:
the software restarts timing and waits for the data of the next input current level;
If the input current level does not change within 5 seconds or when the next input current level is not one of 1/2/3 levels, the input current level is not processed, the output of the corresponding light intensity level is carried out according to the current configuration, and the state 1 is returned;
If the current is received within 5 seconds when the next input current level is one of 1/2/3, switching the current configuration to be the corresponding configuration 1/configuration 2/configuration 3, storing the changed configuration to a local memory, returning to the state 1, and repeating the steps;
In a specific use process, the configuration adjustment instruction is confirmed through the adjustment change of the 6 input currents in sequence of 1-5-4-2-1-4, and when the adjustment process of the 6 input currents is not detected, the operation is equivalent to the operation according to the working mode of a common navigation lamp under the current configuration.
Finally, it should be noted that the above embodiments are only for illustrating the technical solution of the present application, and not for limiting the scope of the present application, and although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made to the technical solution of the present application without departing from the spirit and scope of the technical solution of the present application.
