[0015] In this embodiment, the mains-N1 terminal is electrically connected to the lighting lamp group 1 through a circuit breaker, and the mains-N1 terminal and the mains-L1 terminal are electrically connected with an AC contactor KM4, which includes a coil KM4 and a normally closed contact KM4.

The mains-N1 terminal and the mains-L1 terminal are electrically connected with a KM11 coil, and the KM11 coil is connected with a computer control module DNMK1, which controls the lighting lamp group 1 on and off through program electronic control.

[0016] It is worth noting that the N2 terminal of the mains power supply is electrically connected to the second lighting lamp group through the normally open contact KM22, and the AC contactor KM3 is electrically connected between the N2 terminal of the mains power supply and the L2 terminal of the mains power supply. The AC contactor KM3 includes the normally closed contact KM3 and the coil KM3. The AC contactor KM2 is connected in parallel to the AC contactor KM3. The AC contactor KM2 includes the normally open contact KM2 and the coil KM2. The KM22 coil is electrically connected between the N2 terminal of the mains power supply and the L2 terminal of the mains power supply. The KM22 coil is connected to the computer control module DNMK2. The computer control module DNMK2 controls the on and off of the lighting lamp group 2 through program electronic control.

[0017] In this embodiment, there are a total of 8 lighting lamps, which are divided into two groups. Lighting lamp group 1 includes 4 No. 1 lamps, and the 4 No. 1 lamps are connected in parallel. Lighting lamp group 2 includes 4 No. 2 lamps, and the 4 No. 2 lamps are connected in parallel. The two groups of apron lighting lamps are placed on a lamp panel of a lamp pole. The attached figure is an actual distribution diagram of the 8 lamps on the lamp panel of the high pole lamp. Such distribution is conducive to more uniform illumination of the parking spaces.

[0018] As an application of this embodiment:

[0019] The KM11 coil is controlled by computer control module 1 DNMK1, thereby controlling the 4 No. 1 lamp switches; the KM22 coil is controlled by computer control module 2 DNMK2, thereby controlling the 4 No. 2 lamp switches;

[0020] 1. In energy-saving mode, through the computer control module DNMK1, only 4 No. 1 lamps are turned on, and the working conditions are as follows:

[0021] 11) One or more of the four No. 1 lamps fail, causing the circuit breaker QF1 to trip, causing the KM4 coil to lose power. At this time, the normally closed contact of KM4 on the right automatically closes, causing the coil KM2 to be energized, and the normally open contact KM2 closes, automatically turning on the four No. 2 lamps to ensure lighting;

[0022] 12) The mains 1 is cut off due to the transmission circuit, causing the coil KM4 to be de-energized. At this time, the normally closed contact of KM4 on the right automatically closes, so that the coil KM2 is energized, and the normally open contact KM2 closes, automatically turning on the four No. 2 lamps to ensure lighting;

[0023] 13) Other problems cause the circuit breaker QF1 to trip, causing the coil KM4 to lose power. At this time, the normally closed contact of KM4 on the right automatically closes, causing the coil KM2 to be energized, and the normally open contact KM2 closes, automatically turning on the four No. 2 lamps to ensure lighting;

[0024] 2. In the energy-saving state, through the computer control module DNMK2, only 4 No. 2 lamps are turned on, and the working conditions are as follows:

[0025] 21) One or more of the four No. 2 lamps fail, causing the circuit breaker QF2 to trip, causing the coil KM3 to lose power. At this time, the left normally closed contact KM3 automatically closes, energizing the coil KM1, and the normally open contact KM1 closes, automatically turning on the four No. 1 lamps to ensure lighting;

[0026] 12) The mains 2 is cut off due to the transmission circuit, causing the coil KM3 to lose power. At this time, the normally closed contact KM3 on the left automatically closes, energizing the coil KM1, and the normally open contact KM1 closes, automatically turning on the four No. 1 lamps to ensure lighting;

[0027] 13) Other problems cause the circuit breaker QF2 to trip, causing the coil KM3 to lose power. At this time, the normally closed contact KM3 on the left automatically closes, energizing the coil KM1, and the normally open contact KM1 closes, automatically turning on the four No. 1 lamps to ensure lighting;

[0028] Beneficial effect: When all 8 lamps on the apron high pole lamp are powered by mains 1 or mains 2 alone, if a fault occurs, causing a power outage of mains 1 or mains 2, the aircraft on the stand protected by the high pole lamp will completely lose lighting and enter a dark state. The staff cannot work normally, which has a great impact on the operation. Therefore, the 8 lamps are divided into 2 groups, and connected to mains 1 and mains 2 for power supply at the same time. When operating at night, all 2 groups of 8 lamps can be turned on. Even if there is a problem with one mains or one group of lamps, there is another group of 4 lamps to provide lighting guarantee; or only one group of 4 lamps can be turned on separately in the energy-saving state to ensure the normal lighting of the apron, and when the power supply of the 4 turned-on lamps suddenly fails, the other group of 4 lamps will automatically turn on to ensure the normal lighting of the apron.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
