Fig. 2 is an electrical schematic diagram of the present invention.
Fig. 3 is the structural drawing of cleaning device of the present invention.
Embodiment
Referring to Fig. 1, present embodiment is made up of signal acquisition circuit 1, signal Processing and controlling output circuit 2, power circuit 3 and 4 four parts of automatic flushing device.
Signal acquisition circuit 1, be used for gathering the caused electronic signal variation of concentration change of air mist, it is by infrared ray sensor (model: E18-DSI0C4, Hangzhoupro, Hangzhou is sent out sensing and is played company limited and produce) 5 and reflective mirror 6 constitute, infrared receiving terminal and emitting head have been installed in infrared ray sensor inside, and plane mirror has been installed in infrared ray sensor the place ahead setpoint distance (must have certain space) and corresponding position.
Signal Processing and controlling output circuit 2, be used to handle the electronic signal that collects, and the unlatching of control brightness increasing traffic indicating lamp, it is made up of delay circuit 2-1, blast control circuit 2-2 and output circuit 2-3, described delay circuit 2-1 mainly finishes delay feature by capacitor C 2, after the pick-off signal of signal acquisition circuit 1 is transported to delay circuit, delayed circuit delay (false triggering that can avoid critical conditions and other reasons to cause), signal changes blast control circuit 2-2 over to; The blast control circuit mainly is made up of triode Q1, Q2 and relay J 1, and triode plays the effect of switch, and relay adopts the normally closed contact mode; Output circuit 2-3 is made of the lamp of one group of high brightness, and being in parallel with former stop-light is connected.
Power circuit 3, be used to provide D.C. regulated power supply, the bridge rectifier circuit that it is made up of diode D1～D4, filter capacitor C1, integrated regulator U1 and diode D5, D6 form, and stable 12V DC voltage are provided for signal acquisition circuit 1 and signal Processing and controlling output circuit 2.
Because stop-light of the present invention is mounted in open-air, so through coveing with one deck ash at the emitting head of infrared ray sensor and the surface of reception head unavoidably behind the certain hour, thereby influence the sensitivity of sensor, get on to clean quite inconvenience and will climb to signal lamp, for addressing this problem, the device 7 that utilizes rainwater to clean automatically is equipped with in the present invention respectively above infrared ray sensor 5 and reflective mirror 6, it has a funnel shaped water inlet 7-1, its bottom is provided with communicating pipe 7-2, and infrared ray sensor 5 or reflective mirror 6 surfaces are aimed in the outlet of communicating pipe.
The lamp of described high brightness can be single large diameter spotlight, green or the yellow translucent cover of redness is equipped with in the front of lamp, be installed in the next door of the original signal lamp of corresponding color with it, this form generally is to be complementary with incandescent lamp, metal halogen tungsten lamp, is in parallel with the original signal lamp on circuit.
The traffic lights made from light emitting diode (LED) that grow up for nearly several places, because signal lamp is formed by a lot of LED lamp bank row, so its diameter of the high brightness lamp among the present invention can not be too big, its size must be complementary with the LED lamp, as the miniature searchlight that can adopt PHILIPS Co. to produce, have 100,000 lumen brightness, searchlight is clouded in the former light-emitting diodes ligament, and the green or yellow translucent cover of redness is equipped with in the front of lamp.Can also be with the very strong laser lamp of penetration power, laser lamp as the production of Nuo Weisi photoelectricity science and technology (middle mountain) company limited, diameter can be done very for a short time, the radium-shine module of green glow industry, ruddiness planar laser module (claiming laser lamp again), power 15W is apart from 5KM, structurally, be to be clouded in the gap of former light emitting diode equally, circuit connects in parallel with the original signal lamp.
Principle of work of the present invention is: referring to Fig. 2-1 circuit theory diagrams: the 220V alternating current is through transformer B1 step-down, bridge rectifier, after capacitor C 1 filtering, positive 12V direct supply is exported in the LM7812 voltage stabilizing, as the power supply of infrared sensor, delay circuit and output control circuit.Infrared receiving terminal and emitting head have been installed in E18-DSI0C4 infrared ray sensor inside, plane mirror 6 has been installed in infrared ray sensor the place ahead, the infrared ray that sends when the infrared ray emitting head, can normally turn back to when receiving by reflective mirror 6, internal output circuit 3 pin conducting and output low levels, the A point voltage descends, make Q1, Q2 conducting, relay J 1 adhesive, normally closed contact J1-1 disconnects (Fig. 2-2), at this moment former stop-light L4, L5, L6 operate as normal.When the infrared ray that the infrared ray emitting head sends, when running into the greasy weather, because the refraction and the absorption of mist, infrared ray turns back to the signal weakening that receives head, and internal output circuit ends; Infrared ray sensor 3 pin conductings are also exported high level, the A point voltage rises, the false triggering that causes for fear of critical conditions and other reasons, capacitor C 2 plays buffer action, and voltage is slowly risen, and Q1, Q2 end when making voltage on the C2 arrive certain value through certain hour, relay J 1 discharges, normally closed contact J1-1 closure, L1, L2, L3 enter work at this moment, start the high brightness spotlight.
