The utility model has the characteristics that the apparatus is integrated into a video frequency character overlapping module; the installation is simple and convenient; the modification for show contents and the control arrangement is convenient; the operation is stable.
Description
Technical field
The utility model relates generally to video character stack field, particularly a kind of Vehicular video character overlap-add procedure device.
Background technology
Vehicle is as a kind of mobile transmitting carrier at present, communication mode in the compartment is still for pasting some caution term and promotional content, or provide to the passenger with the form of printed matter, such one is to destroy environment inside car, waste resource, the 2nd, content can't be revised. and the while is along with the continuous maturation of vehicle electronics technology, vehicle-mounted VCD or DVD, supervisory control system, drive recorder etc. have become the obligato configuration of vehicle, and the purposes of these configurations is all very single, does not organically combine.
Summary of the invention and purpose
The purpose of this utility model is the weak point according to above-mentioned existing situation, video character overlap-add procedure device is provided, this device is by single-chip microcomputer, the MB90092 character overlap chip, video amplifies buffer circuit, the RS232 serial communication circuit is formed and is utilized existing vehicle-mounted VCD or DVD on the vehicle, supervisory control system, drive recorder etc., reach following function, function one: can on the picture of playing VCD or DVD, show some caution term and promotional content, function two: can be used in the supervisory control system, the real-time speed of a motor vehicle and time that drive recorder is gathered are superimposed upon on the pilot signal, are convenient to the management of passenger traffic company.
The utility model purpose realizes being finished by following technical scheme:
The utility model is in the actual device design, and this device is made up of single-chip microcomputer, MB90092 character overlap chip, video amplification buffer circuit, FLASH memory, RS232 serial communication circuit.Adopt single-chip microcomputer to the control of MB90092 character overlap chip, utilize RS232 serial communication circuit and recorded vehicle instrument to communicate, the while also utilizes the RS232 serial communication circuit to carry out that character writes in advance, control setting.Whole system adaptability is stronger, can revise in advance very easily according to different tasks, shows the content that needs.
The utility model has the advantages that this device has been integrated into a video character laminating module, simple installation, displaying contents and control setting are revised convenient, and system works is stable.
Summary of drawings
Accompanying drawing 1 is a system flow schematic diagram of the present utility model;
Concrete technical scheme
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing 1, so that technical staff's of the same trade understanding:
The utility model has been integrated into a video character laminating module, only leaves power interface, and video signal interface and the RS232 serial ports that is used for communicating by letter, this device can external 5V, 12V or 24V power supplys, satisfied various specific (special) requirements; Can be used as independently system's installation, also can be installed in monitoring host computer inside, vision signal is through promptly finishing the additive process of character after the module.In supervisory control system, the RS232 serial ports is used for communicating by letter of module and recorder, and the data of recorder are sent to module; And in audio-visual overlapping system, caution term or publicity language are revised in advance and be provided with by software for calculation by the RS232 serial ports.
