Abstract

The invention discloses an airport lighting automatic control method adopting the control method that phototriode relative circuit is used for improving road lamp switch, and adopting a phototriode as an illumination sensing element. While the brightness is high in day time, the phototriode 1.14C1 is turned on, the diode VD3 is also turned on, the voltage drop on the capacitance C2 is 0, both bidirectional trigger tube VD5 and the bidirectional thyristor VT are turned off and the lamp is turned off; on the contrary, in the night, the 1.14C1 is turned off, the voltage drop on the capacitance C2 is not 0, the VD4 and the VT is turned on, and the lamp is turned on automatically; and in the low air light transmittance whether such as rain, snow and fog, the road lamp compensation adjustment is realized by changing the resistance numerical value of the humidity-dependent sensor. And, whether the control circuit is working can be detected by a green LED, when the LED is turned on, the control circuit is working normally; otherwise, the control circuit breaks down, then, an emergency switch can be closed to keep the illumination function of the road lamp. The invention can reduce aircraft incidences in airport and utilize electronic energy reasonably, and can be applied in the automatic control of all the road illuminations.

Description

Automatic control method for airdrome illumination

Technical field

The invention relates to automatic control method for airdrome illumination.

Background technology

According to China's present situation, the runway on the most airports of China and the street lamp at place, airplane parking area all are timing controlled (being to open street lamp at synchronization every day), though this street lamp is widely used, it has two important safety hidden danger:

1 bad weather (light transmittances such as rain, snow, mist are lower) descends pitch-dark, and pilot and flight crew do not see runway and road surface, the airplane parking area, easily cause aircraft run out of the navigation channel or with dangerous situations such as surface car collision.

2 pilots, the ground handling personnel must work under certain illumination brightness.And now the control method of usefulness is regularly, and the time that every day, the sky grew dark changes, like this can not be exactly when pilot and ground handling personnel need the unlatching street lamp, street lamp utilizes unreasonable.

Nowadays the used street lamp in airport is time-controlled (both regularly switch), can make the staff can not be at the timely unlatching street lamp of take like this, and is often driving street lamp when not required the staff.

Bad weather (the lower weather of air light transmittance such as rain, snow, mist) is existing still for causing the major reason of airport accident, and except factors such as wind-force, pitch-dark, pilot does not see runway, staff, and not see airport etc. also be the key factor that causes accident to take place.

So, do not cause that because of seeing aircraft accident is exactly a very serious problem bad weather (the lower weather of air light transmittance such as rain, snow, mist) pilot.In addition, the street lamp open hour might not be staff or pilot's required time.Causing electric light to utilize unreasonablely also just becomes very serious problems and my illumination autocontrol method has solved this problem just, makes utilization of power be tending towards rationalizing.

Summary of the invention

The present invention is in order to overcome the problem that above technology exists, a kind of autocontrol method of airfield lighting street lamp is provided, when bright intensity is lower than certain value, street lamp is opened, street lamp cuts out when being higher than certain value, and can realize compensatory control according to special weather environment (rain, snow, mist etc.), so just can be according to light power, air light transmittance, and the staff need regulate lamplight brightness.

To achieve these goals, the technical solution used in the present invention is: a kind of automatic control method for airdrome illumination, adopt photosensitive triode interlock circuit to improve the control method of road lamp switch, adopt photosensitive triode as the illumination sensing element, when daytime, illumination was very big, phototriode 1.14C1 conducting, also conducting of diode VD3, make that pressure drop is 0 on the capacitor C 2, two-way trigger tube VD5 and all not conductings of bidirectional thyristor VT, lamp does not work, otherwise, not conducting of 1.14C1 at night, on the capacitor C 2 voltage is arranged, make VD4 and VT conducting, lamp automatically can be bright, when running into rain, snow, during the low weather of air light transmittances such as mist, the resistance of moisture sensor C5-M3 can change thereupon, thereby passes through the compensatory control of relay J ZC4-22 realization to light, by light-emitting diode (green) whether circuit is worked and detects, when light-emitting diode is lighted, illustrate that control circuit is working properly; Otherwise illustrate that control circuit breaks down, keep street lighting function by closed emergency button this moment.

Beneficial effect of the present invention: open as required by autocontrol method realization airport street lamp.Therefore, adopt the interlock circuit of photosensitive triode etc. to improve the control method of road lamp switch, when bright intensity is lower than certain value, the street lamp unlatching, street lamp cuts out when being higher than certain value; If do compensatory adjusting by the humistor characteristic during the low weather of air light transmittances such as rain, snow, mist, so not only reason is rather dark and cause contingency when pilot and staff need, and can descend to open street lamp at bad weathers such as mist, rain, snow at once.The present invention not only can reduce the airport and aircraft accident occur, and rationally utilizes electric energy.The present invention can also be applied to the automatic control of all road lightings.

Embodiment

Below in conjunction with the drawings and specific embodiments the present invention is described in further detail: a kind of automatic control method for airdrome illumination, adopt interlock circuits such as photosensitive triode, moisture sensor to improve the control method of road lamp switch, adopt photosensitive triode as the illumination sensing element, adopt moisture sensor to make the compensation control element as air humidity (influencing the air light transmittance).Closed airport street lamp master switch, when daytime, illumination was very big, phototriode 1.14C1 conducting, also conducting of diode VD3, make that pressure drop is 0 on the capacitor C 2, two-way trigger tube VD5 and all not conductings of bidirectional thyristor VT, lamp does not work, otherwise, not conducting of 1.14C1 at night, on the capacitor C 2 voltage is arranged, make VD4 and VT conducting, lamp automatically can be bright.When running into the low weather of air light transmittances such as rain, snow, mist, the resistance of moisture sensor C5-M3 can change thereupon, thereby makes the direct conducting of bulb place circuit by relay J ZC4-22, and lamp automatically can be bright.In addition, realize measuring ability by light-emitting diode: under the situation of airport street lamp master switch closure,, illustrate that control circuit goes wrong if light-emitting diode does not work to bulb, can under the situation of closed emergency button, change new control method, aging method is returned the repair in shop reason.

The present invention is by to the selecting for use of photo resistance, the brightness when the restriction street lamp is opened. and so just can not have street lamp when needed, and open street lamp when not required.The circuit that adopts utilizes the triode light sensitive characteristic, and street lamp is opened automatically; When the low situations of air light transmittance such as running into rain, snow, mist is descended, adopt the compensatory adjusting of moisture sensor characteristic realization street lamp, thereby having solved the pilot does not see runway, the flight crew does not see the problem on airport, has significantly reduced the generation of aircraft accident.When bright intensity is lower than certain value or air light transmittance when low, street lamp is opened, so not only can open street lamp, and reason is rather dark and cause contingency when pilot and staff need at low weather of air light transmittance such as rain, snow, mists at once.
