The control system of the airport navigation aid lamp set comprises: a controller 1, a dimmer 2, and a plurality of lamp drivers; the dimmer is connected with the controller; the lamp drivers correspondingly connected with the lamps 3 are correspondingly connected with one another one by one, the lamps are divided into at least two groups, each group of lamps at least comprises one lamp, and the lamp drivers correspondingly connected with each group of lamps are connected with the dimmer after being connected in series; the dimmer is used for outputting current signals with different frequency values according to the lamp group control signals sent by the controller; each lamp driver controls the corresponding connected lamp to light up or light down based on the frequency value of the current signal.
In particular, the dimmer is a sinewave dimmer.
The lamp group comprises a stop lamp group and a runway state lamp group. The stop bank light group is arranged across the taxiway at the place where the airplane is required to stop and consists of a group of lamps emitting red light towards the predicted intersection point or the approaching direction of the waiting position of the runway, the stop bank light is turned on to indicate that the passage is forbidden, and the turn-off indicates that the passage is allowed; the runway state lamp group is longitudinally arranged at the takeoff position of the runway and on the taxiway entering the runway and consists of a group of lamps emitting red light towards the takeoff direction or entering the runway, the runway state lamp is turned on to indicate that the runway is occupied or other aircrafts enter the runway, and the lamp is turned off to indicate that the runway is not occupied or other aircrafts do not enter the runway. Each group of stop banks or runway status lights may include more than 6 lights.
The working principle of the control device of the airport navigation aid lamp set is briefly described as follows:
at present, an LED lamp is driven by the lamp to be lightened and the light level of the LED lamp is adjusted, a dimmer supplies power, the current frequency is fixed to be 50Hz, the current is divided into 2.8A, 3.4A, 4.1A, 5.2A and 6.6A, and the current corresponds to 5 levels. When the LED lamp drive detects that the input current is 2.8A and the current frequency is 50Hz, the lamp drive outputs corresponding direct current, the LED lamp is lightened, the light is 1 polar light at the moment, and if other input currents are detected, the lamp is started to have corresponding light level. According to the design principle of lamp driving, when the current input frequency changes, the lamp driving can detect the frequency change, and the lamp is controlled to be turned on or turned off through relevant setting, the current frequency adjustable range of the current special dimmer is 31 Hz-120 Hz, and the lighting control can be realized when the lamp driving detects that the input current frequency is 31Hz and the current is 2.8A, the light level is 1 level light, and the light extinguishing control can be realized when the lamp driving detects that the input current frequency is 32Hz and the current is 2.8A. The sine wave dimmer can adjust the current frequency, in the embodiment, one frequency-adjustable sine wave dimmer is used as the power supply equipment, as the navigation aid lamp supplies power in a series connection mode, the frequency and the current output by the dimmer are the same as those of all lamps supplied with power by the dimmer, if only one group of lamps is carried by the dimmer, all the lamps can be set to be turned on at 31Hz and turned off at 32 Hz. When the dimmer has two sets of lamps, numbers 1# and 2#, the two sets of lamps have 4 states according to the need of the anti-runway intrusion system, namely:
no. 1 lighting state; lighting 2 #;
no. 1 lighting in the 2 nd state; 2# extinguishes;
no. 1 extinguishment in State No. 3; lighting 2 #;
no. 1 extinguishing in the 4 th state; 2# extinguishes;
4 different frequencies are used for representing 4 states, and two groups of lamp drives are respectively set according to the 4 frequencies, so that the lamps can realize different on-off control under different frequencies, namely:
when the input current frequency is 31Hz, the No. 1 lamp is lighted; lighting 2 #;
when the input current frequency is 32Hz, 1# is lightened; 2# extinguishes;
when the input current frequency is 33Hz, the No. 1 is extinguished; lighting 2 #;
when the input current frequency is 34Hz, the No. 1 is extinguished; 2# extinguishes;
by analogy, when the lamps carried by the dimmer have three groups, the lamp numbers are 1#, 2# and 3#, according to the requirement of a runway intrusion prevention system, the three groups of lamps have 8 states, 8 different frequencies are used for representing the 8 states, namely 31 HZz-38 Hz, and the three groups of lamp drives are respectively set according to the 8 frequencies, so that the three groups of lamps realize different on-off control under different frequencies. That is, the number of lamp groups grouped may be less than or equal to the number of frequency values of the adjustable range of the current frequency of the sinewave dimmer. The working principle of the control system of the airport navigation aid lamp set is further explained by combining with a specific application scene as follows:
in an airport, 3 groups of runway status lights 3 need to be installed, the switching time of the 3 groups of runway status lights is possibly inconsistent, a dimmer 2 is used for supplying power, a computer is used for installing dimmer control software 1, and the possible state combinations of the 3 groups of runway status lights are calculated as follows:
no. 1 lighting state; lighting No. 2 and lighting No. 3;
no. 1 lighting in the 2 nd state; 2# extinguishes, 3# extinguishes;
no. 1 lighting in the 3 rd state; 2# lights up, 3# lights out;
no. 1 lighting in the 4 th state; 2# is turned off, and 3# is turned on;
no. 1 extinguishment in State 5; 2# extinguishes, 3# extinguishes;
no. 1 extinguishing in the 6 th state; lighting No. 2 and lighting No. 3;
no. 7 status 1 extinguishment; 2# lights up, 3# lights out;
no. 8 status 1 extinguishment; 2# is turned off, and 3# is turned on;
8 different frequencies are used for representing 8 lamp group states, and 8 lamp group driving is set according to the 8 frequencies, so that different lamp groups can realize different on-off states under different frequencies, and the 1 st state to the 8 th state are realized when input current frequency is 31Hz-38 Hz.
For the first group of lamps, the lamp driving should be set as follows:
when the lamps detect that the input current frequencies are 31Hz, 32Hz, 33Hz and 34Hz, the lamps are set to be lightened;
when the lamp detects that the input current frequencies are 35Hz, 36Hz, 37Hz and 38Hz, the input current frequencies are set to be extinguished;
for the second group of lamps, the lamp driving should be set as follows:
when the lamps detect that the input current frequencies are 31Hz, 33Hz, 36Hz and 37Hz, setting the input current frequencies to be lightened;
when the lamp detects that the input current frequencies are 32Hz, 33Hz, 35Hz and 38Hz, the input current frequencies are set to be extinguished;
for the third group of lamps, the lamp driving should be set as follows:
when the lamps detect that the input current frequencies are 31Hz, 34Hz, 36Hz and 38Hz, the input current frequencies are set to be lightened;
when the lamp detects that the input current frequencies are 32Hz, 33Hz, 35Hz and 37Hz, the input current frequencies are set to be extinguished;
after the setting is finished, the lamps are arranged in place according to the lamp grouping, and if the system requires to realize the 2 nd state, namely 1# lighting; 2# extinguishes, 3# extinguishes; the anti-runway intrusion system sets the dimmer to have an input current frequency of 12Hz through dimmer software, and at the moment, after each group of lamps detect the current frequency, different switch states can be output according to the setting of the software, namely 1# is lightened; the No. 2 is extinguished, and the No. 3 is extinguished, so that the design requirement of the runway lamp state prevention is met.
The frequency value of the output current signal is changed by the dimmer according to the corresponding relation between the preset lamp bank states and the frequency value, the lamp is controlled to be switched on and off under the recognition of the driver connected with the lamp, the lamp is not controlled to be controlled by transmitting the control signal through a power carrier, the control delay of the lamp is very low, the lamp is not influenced by factors such as bandwidth and interference, the accuracy of the control of the lamp bank is improved, the driver connected with the lamp is used for controlling the switch of the lamp according to the frequency value of the current signal, a single lamp monitoring unit is not used for controlling a single lamp, the additional installation of the single lamp monitoring unit is not needed, the influence of the fault of the single lamp monitoring unit on the control of the lamp bank is avoided, and the reliability of the control of.
