Detailed description of the invention
Understand essence of the present invention better for convenience of those skilled in the art, below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
As shown in Figure 1, a kind of strobe warning lamp with laser ranging function, comprising: base 1, is arranged on the lampshade 2 on base 1, is arranged on the LED light source 3 in lampshade 2, and the controller 4 be connected with LED light source 3 and built-in power 5-1; It is characterized in that, described LED light source 3 is the double-colored light source of reddish yellow, and controller 4 is connected with laser range sensor 6, and controller 4 controls LED light source 3 according to the signal that laser range sensor 6 detects and sends different frequency or photochromic light.
Wherein, described LED light source 3 is red LED device and yellow led device alternately point other LED.Described controller 4 and laser range sensor 6 are all built on base 1, to simplify structure, are convenient to the movement realizing strobe warning lamp.
For ensureing alarming effect, base 1 is provided with erection column, described LED light source 3 is around being arranged on erection column surrounding, and the Luminous Ring that formation about at least two is parallel, around LED light source 3, be provided with reflector 7.By above-mentioned setting, make the 360 ° of luminescences of whole warning lamp energy, and in real work, even if the part LED light source of certain Luminous Ring damages the normal use also not affecting warning lamp.
In the present embodiment, preferred controller is STC89C51 single-chip microcomputer, and preferred built-in power 5-1 is made up of as shown in Figure 2 drive IC 7201 and respective peripheral circuit.During concrete connection, the Diming of drive IC 7201 end connects the pwm signal output of STC89C51 single-chip microcomputer, open to realize controlling reddish yellow dual-colored LED light source, close and and flicker frequency; The data receiver Rx of laser range sensor, data transmitting terminal Tx are cross connected to data transmitting terminal Tx, the data receiver Rx of STC89C51 single-chip microcomputer, exchange to realize sensing data.
In practical application, the strobe warning lamp that the present embodiment provides is applied on automobile, structured flowchart as shown in Figure 3, LED light source can also be connected with external power supply, only need be provided with the plug be connected with outside constant voltage source on LED light source, such as vehicle-mounted cigarette lighter, is connected with constant voltage source 5-2 by vehicle-mounted cigarette lighter.
Adopt the laser range sensor of the safe laser of 905nm to human eye fanout free region to realize contactless telemeasurement in safe distance detection.The Data Collection of range sensor with and the unlatching of reddish yellow dual-colored LED and flicker frequency be controlled by single-chip microcomputer embedded software.Specific works flow process is as shown in Figure 3.When laser range sensor, to detect 50-100 rice interval, and when there is a moving vehicle in front, red danger early warning lamp continues bright, and Amber Alerts lamp sends alarm signal with strobe mode, and flash rate is 0.75 time/second; When 30-50 rice is interval, during the moving vehicle of front, red danger early warning lamp sends early warning signal with strobe mode, and flash rate is 0.75 time/second, and Amber Alerts lamp is closed; When interval at 10-30 rice, when there is a moving vehicle in front, red danger early warning lamp sends early warning signal with strobe mode, and flash rate is 1 time/second, and Amber Alerts lamp is closed; When within 10 meters, when there is a moving vehicle in front, red danger early warning lamp sends early warning signal with strobe mode, and flash rate is 3 times/second, and Amber Alerts lamp is closed.
Above-mentioned 0.75 time/second, 1 time/second, 3 times/second is all that some more typical frequency values are selected, in other embodiments, can change these frequency values as required, as long as its final purpose can realize the differentiation of distance, and distance can be reached more closely to the effect that people's sense of urgency is stronger.
Above detailed description of the invention has been described in detail essence of the present invention, but can not limit protection scope of the present invention with this.Apparently, under the enlightenment of essence of the present invention, the art those of ordinary skill also can carry out many improvement and modification, such as double-colored for reddish yellow light source is replaced into the LED component being simultaneously packaged with emitting red light chip and Yellow luminous chip, then by each LED around being arranged on around erection column.Such as above-mentioned strobe warning lamp is applied in the occasions such as plant equipment, road, harbour again.It should be noted that these improve and modify all to drop within claims of the present invention.
