Summary of the invention
The objective of the invention is to cause shortcomings such as potential safety hazard inadequately, a kind of vehicle tracking LED illumination light-dimming method that is used for vcehicular tunnel that a kind of energy-saving effect is better, reliability is higher is provided to excessive illumination, hole brightness that the tunnel illumination system exists.
A kind of infrared vehicle that is used for vcehicular tunnel is followed the tracks of LED illumination light-dimming method, it is characterized in that this method comprises the steps:
Infrared sensor is installed in step 1. 180 meters positions outside apart from tunnel portal of highway, and whether be used for detecting has vehicle will pass through the tunnel; In the tunnel, begin whenever infrared sensor is being installed from tunnel portal at a distance from 180 meters illumination LED light fixtures apart from the both sides, tunnel, infrared sensor is used to detect the traveling-position of vehicle in the tunnel; In the tunnel, on every LED light fixture a light adjusting controller is installed, is used for the LED light fixture is carried out brightness adjustment control.
Step 2. pair vcehicular tunnel vehicle tracking LED illumination light adjusting controller initialization, the initialization object comprises single-chip microcomputer clock frequency, input and output, built-in variable, register, nonvolatile memory and the interruption in the controller; In the tunnel no car through the time light adjusting controller control LED lamp illumination be 20% of full power.
Whether the infrared sensor of step 3. 180 meters positions outside apart from tunnel portal of highway detects has vehicle will pass through the tunnel; To pass through the tunnel if detected vehicle, execution in step 4, otherwise the LED light fixture repeats this step with the 20% illumination illumination of full power in the tunnel.
The both sides LED lamp of 180 meters distances is through light adjusting controller control LED lamp full power output illumination in step 4. tunnel face to the tunnel, and the LED lamp of other position still throws light on execution in step 5 with 20% illumination of full power.
Step 5. is worked as position, tunnel face infrared sensor and has been detected vehicle through out-of-date; Detection information is passed to 180 meters outer light adjusting controllers through 485 buses; The both sides LED lamp illumination full power of 360 meters distances in this moment tunnel face to the tunnel; Other LED lamp still throws light on execution in step 6 with 20% illumination of full power.
The next infrared sensor that step 6. is worked as vehicle heading has detected vehicle through out-of-date; Detection information is passed to the next light adjusting controller apart from 180 meters distances of this light fixture through 485 buses; The both sides LED lamp illumination full power along 360 meters distances of vehicle heading that begin from this lamp position this moment, other LED lamp is with the 20% illumination illumination of full power.
Step 7. has detected vehicle through out-of-date when last infrared sensor, the both sides LED lamp illumination full power of 180 meters distances that begin from this lamp position, and other LED lamp is with the 20% illumination illumination of full power; Forward step 3 to.
Beneficial effect of the present invention: 1, LED illumination light modulation real-time is high, and control is simple; 2, this method control precision is higher; 3, this method energy-saving effect is better.
