Abstract
The utility model discloses a light supplement system of a vehicle camera. The system comprises a central single-chip microcomputer, the central single-chip microcomputer is connected with a signal collection circuit, an LED lamp, an infrared lamp, a CAN bus circuit and a Max232 control chip, and the Max232 control chip is connected with a serial-port interface. According to the utility model, the capability of light-supplement correction of the vehicle camera is greatly improved.
Description
Technical field
The utility model relates to vehicle-mounted camera field, is specially a kind of vehicle-mounted camera light-supplementing system.
Background technology
At present, the light compensating lamp of vehicle-mounted camera, dark in the situation that, light filling effect is bad, inadequate for the illuminance of camera focal length direction, and it is that to take the light sensation of camera itself be switch, so sometimes, in evening, meeting is light yellow always, so the light filling brightness of itself is also inadequate. and being badly in need of a kind of vehicle-mounted camera light-supplementing system is that camera carries out light filling.
Utility model content
The purpose of this utility model is to provide a kind of vehicle-mounted camera light-supplementing system, to solve the inadequate problem of the light filling brightness of prior art vehicle-mounted camera own.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of vehicle-mounted camera light-supplementing system, it is characterized in that: include center single-chip microcomputer, center single-chip microcomputer has access to the signal acquisition circuit that is connected with vehicle-mounted camera, be arranged on LED lamp and infrared lamp near vehicle-mounted camera, center single-chip microcomputer also has access to CAN bus circuit, Max232 control chip, and wherein Max232 control chip has access to serial interface.
Described a kind of vehicle-mounted camera light-supplementing system, is characterized in that: on the single-chip microcomputer of center, also have access to EEPROM.
The utility model adopts CAN bus in conjunction with RS232 serial ports system, simple in structure, adopt custom-designed signal acquisition circuit, control LED lamp and infrared lamp are opened and are carried out the correction of camera light filling, can also notify external equipment, camera, in work or non-operating mode, supports RS232 serial mode to carry out the correction of camera light filling; Support CAN bus mode to carry out the correction of camera light filling, the advantage of this equipment maximum is to allow vehicle-mounted camera light filling capability for correcting greatly promote.
Accompanying drawing explanation
Fig. 1 is the utility model structural principle block diagram.
Embodiment
As shown in Figure 1.A kind of vehicle-mounted camera light-supplementing system, include center single-chip microcomputer 1, center single-chip microcomputer 1 has access to the signal acquisition circuit 5 that is connected with vehicle-mounted camera, be arranged on LED lamp 4 and infrared lamp 3 near vehicle-mounted camera, center single-chip microcomputer 1 also has access to CAN bus circuit 6, Max232 control chip 7, and wherein Max232 control chip 7 has access to serial interface 8.On center single-chip microcomputer 1, also have access to EEPROM2.
The utility model comprises center single-chip microcomputer 1, EEPROM2, infrared lamp 3, LED lamp 4, signal acquisition circuit 5, CAN bus circuit 6, MAX232 control chip 7, serial interface 8.Center single-chip microcomputer 1 is controlled the work of whole system, when signal acquisition circuit 5 collects camera working signal, turn on infrared lamp 3, LED lamp, when signal acquisition circuit 5 does not collect camera working signal, close infrared lamp 3, LED lamp, in the time of camera work, send director data to MAX232 control chip 7, serial interface 8 and CAN bus circuit 6 simultaneously, when external device needs camera work, also can send director data to MAX232 control chip 7, serial interface 8 and CAN bus circuit.MAX232 control chip 7, serial interface 8 and CAN bus circuit also can receive external equipment data and control infrared lamp 3,4 opening and closing of LED lamp to center single-chip microcomputer.EEPROM2 storing received data and turn on the number of times of closing infrared lamp 3, LED lamp 4, and the data such as number of resets of center single-chip microcomputer 1.
The utility model is mainly for vehicle-mounted camera, to take pictures and record a video night to carry out the system of light filling.For at night darkness in the situation that, for camera focal length direction provides illumination.Can also provide data interaction function by serial ports and CAN bus circuit.
