Abstract
The invention discloses a warning lamp for municipal road construction. The warning lamp is characterized by comprising a 12V direct-current power supply, an ambient light detection circuit, an ultralow frequency oscillator, an electric level photovoltaic conversion and double-direction controllable silicon triggering circuit and a light emitting diode display circuit. The warning lamp for municipal road construction adopts a light emitting diode flashing mode, has a better warning effect than single red light at night and emits eye-catching red flashing light at night, so that the double purposes of warning at a construction site at night in an unattended manner are achieved. The circuit has two functions of light control and flashing. The circuit not only can control the warning lamp to be turned on automatically at nightfall and drive the warning lamp to work in a flashing state, but also can control the warning lamp to be turned off automatically at dawn. The condition that most of the traditional red warning lamps emit invariable red light and have a poor actual warning effect is changed.
Description
Technical field
The invention belongs to application of electronic technology field, relate to a kind of municipal road construction warning lamp.
Background technology
At city laying road, lay in the municipal engineering construction such as water supply and sewerage pipeline, coal gas liquefied gas or natural gas line, underground electric light conduits, communication cable and optical cable, in order to safeguard traffic safety, usually hang red warning lamp in job sites such as the ditch holes of road excavation, prompting pedestrians at night or vehicle are avoided falling in dangerous ditch hole, but this red warning lamp majority sends constant red light, and actual alarming effect is not good enough.
Accordingly, municipal road construction warning lamp of the present invention, uses red light emitting diodes flashing mode, has better alarming effect at night more than single red light, in night, send noticeable red passage of scintillation light, thus realize job location warning at night and unserviced dual purpose.
The circuit of municipal road construction warning lamp of the present invention possesses light-operated and flicker two kinds of functions, can control warning lamp and automatically open, and be operated in blink states, automatically can be closed by warning lamp again after daybreak after darkness.
Municipal road construction warning lamp has that circuit is simple, working stability, dependable performance, easy for installation, circuit only uses a small amount of common discrete component, and cost of manufacture only needs twenties yuan, is suitable for factory's batch exploitation.
Below describe in detail municipal road construction warning lamp of the present invention necessity involved in implementation process, guardian technique content.
Summary of the invention
Goal of the invention and beneficial effect: municipal road construction warning lamp of the present invention, use red light emitting diodes flashing mode, better alarming effect is had more than single red light at night, in night, send noticeable red passage of scintillation light, thus realize job location warning at night and unserviced dual purpose.
The circuit of municipal road construction warning lamp of the present invention possesses light-operated and flicker two kinds of functions, can control warning lamp and automatically open, and be operated in blink states, automatically can be closed by warning lamp again after daybreak after darkness.Change traditional red warning lamp majority and send constant red light, and the situation that actual alarming effect is not good enough.
Circuit working principle: municipal road construction warning lamp forms the complementary ultralow-frequency oscillator of a frequency-adjustable by a NPN type triode VT1 and PNP type triode VT2, and its frequency of oscillation regulates by potentiometer RP.At the base stage of NPN type triode VT1 and an indirect photo resistance RG of 9V DC power cathode, composing environment light testing circuit, controls automatically to realize the low light level.Control photoelectricity by the collector electrode of PNP type triode VT2 by current-limiting resistance R2 drives bidirectional triode thyristor coupler G1 to work, photoelectricity drives bidirectional triode thyristor coupler G1 to control conducting or the cut-off of great power bidirectional controllable silicon BCR, and great power bidirectional controllable silicon BCR directly control lighting of 24 red light emitting diodes or extinguishes.
Time by day, because ambient light is brighter, photo resistance RG light is irradiated, and its resistance is less, makes the base voltage of NPN type triode VT1 constant in electronegative potential, so the complementary ultralow-frequency oscillator failure of oscillation be made up of NPN type triode VT1, PNP type triode VT2.Now NPN type triode VT1, PNP type triode VT2 all end, the current collection very electronegative potential of PNP type triode VT2, photoelectricity drives bidirectional triode thyristor coupler G1 not work, and great power bidirectional controllable silicon BCR ends, 24 red light emitting diodes do not work, and whole circuit remains static.When after darkness, photo resistance RG because of unglazed irradiation make its resistance increase (being about 1M Ω), lose the control ability to NPN type triode VT1 base stage, so, the complementary ultralow-frequency oscillator starting of oscillation be made up of NPN type triode VT1, PNP type triode VT2 works, and the collector electrode output potential of PNP type triode VT2 starts high and low change periodically occurs.When it exports as high level, make photoelectricity drive bidirectional triode thyristor coupler G1 work and drive great power bidirectional controllable silicon BCR conducting, red light emitting diodes is lighted; When it exports as low level, photoelectricity drives bidirectional triode thyristor coupler G1 to quit work again, and great power bidirectional controllable silicon BCR recovers cut-off, and 24 red light emitting diodes extinguish again.Like this, the light on and off of 24 red light emitting diodes controlled by ultralow-frequency oscillator, works again and again and makes 24 red light emitting diodes be in blink states.
