Abstract

The utility model relates to a control device of a numeric control lamp of an automotive vehicle, composed of an encoder A, signal lines N (M), decoding control devices and safety devices B. At the time of working, the starting and closing signals of switches for each lamp of a vehicle are sent to the input port of the encoder A. Serial digital control signals are obtained from the output terminal of the encoder A. The serial digital control signals are sent to the decoding control devices and the safety devices B near each lamp through optical cables N or cables M to decode out various lamp control signals to control different kinds of lamplight. The utility model has the advantages of simple structure, convenient installation, simple circuits, low failure rate, easy maintenance and cable saving and is suitable for the design of circuits of a new vehicle and the alteration of circuits of a used vehicle of automotive vehicles.

Description

The Vehicular lamp numerical control device

The utility model relates to the illumination and the signal lamp of power actuated vehicle.

The car light control of existing power actuated vehicle is the power supply that is opened and closed each light by near the various switches the operator platform, behind the safety device of concentrating, is sent to each light fixture by each corresponding lamp line circuit again.Various and the every line of circuit all is charged, is the hidden danger that " bonding " burns line; When meeting patch cord in the cabling way, contact is many, fault is also many, checks very trouble during maintenance.Various warning indicating system devices have appearred for this reason, as: Chinese patent (1) application number 89211779, (2) application number 93214869, (3) application number 95219644, (4) application number 90208235 etc., and no matter how accurately sensitive these warning indicating devices are, all can only indicate certain street lamp light that fault is arranged, but concrete trouble point, particularly line fault point still are difficult to search.

The purpose of this utility model provides a kind of numerical control device of light, and it can make the lamp line of existing complexity be reduced to a signal wire (SW) and make the lamp line circuit become simple especially, fundamentally reduces line fault.

This practical technical scheme is as shown in Figure 1: each switch output line of operator platform is all inserted among the coder A behind the coding, the serial signal of being exported, deliver to by a cable line N or shielding wire M and to decode various control modulating signals among near be installed in each light fixture all around decoding control and the safety device B and remove to control left front lamp ZD, right front lamp YD, tail headlight WD.Circuit such as Fig. 2 in the coder, integrated circuit ZD6631/32 are the coder and decoder ics of a pair of eight road level control, and the infrared light that infraluminescence pipe D sends is delivered in each demoder by optical cable; Or draw electric signal at the OUT place, deliver to each demoder by shielding wire.Decode and control and the interior circuit of safety device such as Fig. 3, the 337th, integrated infrared receiving amplifier, the signal of output are sent into and are solved each corresponding modulating signal among the decoding integrated circuit ZD6632, as decoding with the then direct feed-in 2 end pin of shielding wire.Decode signal and after aerotron is done level translation, control master control ICBTS620.The far and near photocurrent of headlight is bigger, with the parallel connection of BTS620 two-way; Other lamp is all only used single channel 50W, and the main power source of each master control IC all is connected to wire fuse, and there is short-circuit protection IC inside, and by double insurance, circuit is safer.

The utility model has the advantages that: only need at lighting switch to inserting cover coding a---decoding device between the light fixture, so structure is comparatively simple.The coding and decoding device is made the finished product module respectively, so install very convenient.Owing near the wire fuse group the lighting switch, move in light fixture neighbouring the decoding control and safety device simultaneously, so only need a signal wire (SW) between from the operator platform to the light fixture; The car light circuit of vehicle is just simple especially.Saved copper cash, reduce the trouble point, and maintenance is also convenient.Master control IC uses the smart power switch BTS620/621 of Siemens Company, and various defencive functions are complete, and damage rate is few.Alarm indication if desired, each master control IC the 5th pin detection terminal, exportable breakdown signal, very convenient.

Claims

1. the Vehicular lamp numerical control device is characterized in that lighting switch to inserting a kind of numerical control device between the light fixture, and this device all is connected to the coder input end to various control light switchs; The signal of coder output is delivered to the decoding control and the safety device that place near each light fixture by signal wire (SW) and is decoded respectively, thereby controls light.

2. device according to claim 1 is characterized in that master control, wire fuse and demoder are integrated, near each light fixture that is placed in; Can also can be in light fixture outside light fixture.

3. device according to claim 1, its feature also are between coder and the demoder, promptly only need a signal wire (SW) to link between operator platform and each light fixture, use the different terminals on the coding and decoding device, can use cable, also can use cable line.
