Refer to Fig. 4, Fig. 4 is the wireless induction type Lighting System based on RFID mechanics of communication based on vehicle lamp for lighting floor of the present invention, this wireless induction type Lighting System based on RFID mechanics of communication can when the automobile of car owner close to this light place, automatic luminous throws light on, in suburb etc. without light or the darker place of light, can throw light on for car owner, facilitate car owner to observe the situation of vehicle periphery, Experience Degree and the satisfaction of car owner can be increased.
This wireless induction type Lighting System based on RFID mechanics of communication comprises above-mentioned light, RFID inductor, responds to described RFID inductor the RFID contactless card (being built-in with the car key of RFID), the first relay that coordinate.Described RFID inductor can be identical with the setting position of keyless access system of the prior art and mode, and in the present embodiment, described RFID inductor is located in the housing of described back mirror.Described RFID contactless card can be IC-card, also can be car key, only needs to arrange RFID in car key.
The power end of described RFID inductor is connected with VCC power supply, described RFID inductor has the electrical signal be connected with the first end of the coil J1 of described first relay, the second end ground connection of described coil J1, the electrical signal of described RFID inductor is also connected with the first end of the contact KM-1 of described first relay, and second end of described contact KM-1 is electrically connected with described light.In the present embodiment, described power supply can be independently power supply, also can be the power supply of automobile storage battery.
In the present embodiment, described RFID inductor can respond to the distance of several meters, as long as select commercially available RFID inductor.
Refer to Fig. 5, as preferably, in order to save power supply, the Lighting System of the present embodiment, also has the normally closed switch K closing light after user enters vehicle.In the present embodiment, normally closed switch button (scheming not shown) can be embedded the position near main driving room on operator's station, makes car owner can select as required to close or open light.The first end of described normally closed switch K is connected with second end of described contact KM-1, and the second end of described K switch is connected with described light.
Refer to Fig. 6, in another embodiment, the closedown of described light can realize in the following manner:
In the manner, comprise one for detecting ignition detector, a control chip (in the present embodiment, this chip can be lead or door chip), the second relay that whether vehicle lights a fire.The mouth of described ignition detector is connected with the first input end of described Exclusive-OR gate (XOR gate) chip, second input end of described Exclusive-OR gate (XOR gate) chip is connected with second end of described contact KM-1, the mouth of described Exclusive-OR gate (XOR gate) chip is connected with the first end of the coil J2 of described second relay, the second end ground connection of described coil J2, the mouth of described Exclusive-OR gate (XOR gate) is also connected with the first end of the contact KM-2 of described second relay, and second end of described contact KM-2 is connected with the power input of light.In the present embodiment, described KM-2 is open contact.
In the present embodiment, when RFID inductor senses the RFID matched, RFID inductor sends high level, coil electricity adhesive, and contact KM-1 closes, and Exclusive-OR gate (XOR gate) chip receives this electric signal; If when ignition detector does not detect ignition signal, send low level to Exclusive-OR gate (XOR gate) chip, Exclusive-OR gate (XOR gate) chip then exports high level signal, the KM-2 closing of contact, and light is bright; If ignition detector detects ignition signal, send high level to Exclusive-OR gate (XOR gate) chip, Exclusive-OR gate (XOR gate) chip is output low level signal then, and KM-2 contact becomes off-state, and light is gone out.
By being mutually linked of ignition detector, control chip and RFID, the open and close realizing light that can be intelligent.Before not striking sparks, when car owner is within the scope of induction zone, light is bright, and after sparking, represent that car owner is without the need to this light, light is gone out, without the need to as needing people for carrying out switch control rule in such scheme.This programme provides more convenience for car owner, and Experience Degree and the satisfaction of car owner are better.
In other examples, described Exclusive-OR gate (XOR gate) chip can adopt same or door chip replacement, meanwhile, needs KM-2 to be set as normally closed switch.
In the present embodiment, in order to ensure that RFID inductor successfully can drive the coil J1 of the first relay, a chip can be added between the electrical signal of described RFID and the coil J1 of described first relay, the electric signal that RFID inductor exports, by after this chip process, can ensure that the coil J1 of the first relay is driven.Same, in order to ensure that the coil J2 of the second relay is successfully driven, also can said chip be increased.
These are only embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification sheets of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
