Described automobile tunnel safe guidance device, it designs further and is, described infrared emission head and infrared receiving terminal are 0.8 meter apart from ground level.
Described automobile tunnel safe guidance device, it designs further and is, the distance between described each infrared detecting unit is 3 meters.
Described automobile tunnel safe guidance device, it designs further and is, described infrared detecting unit has 17.
Described automobile tunnel safe guidance device, it designs further and is, described display has five kinds, is respectively: start at from tunnel portal, first to the 3rd infrared detecting unit the first display that is first group of infrared detecting unit is corresponding; 4th to the 6th infrared detecting unit the second display that is second group of infrared detecting unit is corresponding; 7th to the tenth infrared detecting unit the 3rd display that is the 3rd group of infrared detecting unit is corresponding; 11 to the 13 infrared detecting unit the 4th display that is the 4th group of infrared receiver is corresponding; 14 to the 17 infrared detecting unit the 5th display that is the 5th group of infrared receiver is corresponding.
Described automobile tunnel safe guidance device, its further design be, described infrared emission head is made up of the 38kHz square wave signal generator of dutycycle 20%, power amplifier and light emitting diode; Via a signal, multiple infrared receiving terminals that described each group of infrared detecting unit is corresponding differentiate that latch cicuit is connected with one or door respectively, each or door is connected with processor respectively.
Whether the present invention precisely can measure 50 meters of at tunnel face place has vehicle, gives follow-up hot-short with early warning timely.Than the high power lighting lamp used now, this infrared detection device is safe and reliable, and install simple, with low cost, key is a large amount of economize on electricitys, meets the energy saving policy of country, can large-scale popularization.

Detailed description of the invention
Below in conjunction with Figure of description and embodiment, the present invention is further described.
Shown in composition graphs 1-Fig. 3, this automobile tunnel safe guidance device, be arranged in tunnel, comprise some infrared detecting units 1, processor and highlighted display screen 2, described some infrared detecting units are longitudinally distributed in tunnel-side from tunnel portal, detect each infrared detecting unit corresponding part in tunnel and whether there is vehicle; Described processor receives the detection signal of described infrared detecting unit, and contain the display of the positional information of distance tunnel portal nearest vehicle to highlighted display screen output packet, and described highlighted display location is relative with tunnel outer in tunnel portal top.
Described infrared detecting unit comprise be symmetricly set in infrared emission head on two side, tunnel (shown in figure, A
1-A
17) and infrared receiving terminal (shown in figure, B
1-B
17).Described infrared emission head and infrared receiving terminal are 0.8 meter apart from ground level.Described automobile tunnel safe guidance device, it designs further and is, the distance between described each infrared detecting unit is 3 meters.Described infrared detecting unit has 17.
As shown in Figure 4, described display has five kinds, be respectively: start at from tunnel portal, with first to the 3rd infrared detecting unit the first display that is first group of infrared detecting unit is corresponding, this signal makes highlighted display screen show " having car carefully to go slowly in 10 meters "; With the 4th to the 6th infrared detecting unit the second display that is second group of infrared detecting unit is corresponding, this signal makes highlighted display screen show " having car carefully to go slowly in 20 meters "; With the 7th to the tenth infrared detecting unit the 3rd display that is the 3rd group of infrared detecting unit is corresponding, this signal makes highlighted display screen show " having car carefully to go slowly in 30 meters "; With the 11 to the 13 infrared detecting unit the 4th display that is the 4th group of infrared receiver is corresponding, this signal makes highlighted display screen show " having car carefully to go slowly in 40 meters "; With the 14 to the 17 infrared detecting unit the 5th display that is the 5th group of infrared receiver is corresponding, this signal makes highlighted display screen show " having car carefully to go slowly in 50 meters ".
Contrast Fig. 5 and Fig. 6, described infrared emission head is made up of the 38kHz square wave signal generator of dutycycle 20%, power amplifier and light emitting diode; Via a signal, multiple infrared receiving terminals that described each group of infrared detecting unit is corresponding differentiate that latch cicuit is connected with one or door respectively, each or door is connected with processor respectively.The task of processor be by receive or gate signal by ascending sequence.As or door 1 with or door 3 have signal, then export the first display, as or door 2 or door 4 or door 5 have signal then to export the second display.All the other situations are analogized
By said system, only need 17 infrared probe unit (every unit comprises an infrared emission head and an infrared receiving terminal), the light-emitting diode display and the simple system processor (as single-chip microcomputer MSP430 etc.) that form highlighted display screen get final product completion system.
Whether the present invention precisely can measure 50 meters of at tunnel face place has vehicle, gives follow-up hot-short with early warning timely.Than the high power lighting lamp used now, this infrared detection device is safe and reliable, and install simple, with low cost, key is a large amount of economize on electricitys, meets the energy saving policy of country, can large-scale popularization.
