Abstract
The utility model discloses a simulated inspection system for vehicle sound equipment. The simulated inspection system comprises a computer, wherein the computer is connected with a mouse and a display, the computer is connected with an anti-interference circuit A, an anti-interference circuit B and a TTL circuit via an RS232 signal processing circuit, and the anti-interference circuit A and the anti-interference circuit B are connected with a CGI signal processor. The simulated inspection system can realize communication between detected vehicle sound equipment and a computer serial port, and can simulate a plurality of vehicle sound equipment display screens, operating panels, and the like via software so as to control the detected vehicle sound equipment for carrying out a plurality of actions. The simulated inspection system is high in versatility and flexibility, and can save a large amount of equipment purchasing fund and reduce stock, and inspection equipment scrapping caused by some sound equipment stop production or transformation does not happen to manufacturing enterprises, thus waste can be avoided.
Description
Technical field
The utility model relates to a kind of automobile audio check system, especially a kind of automobile-used sound equipment emulation check system of utilizing computer control and demonstration, highly versatile, cost saving.
Background technology
At present, the automobile audio that some are comparatively high-grade often is made up of three separate units, that is: main system of audio, display screen, guidance panel etc.Enterprise is when producing main system of audio, and existing inspection method is: buy display screen, the guidance panel of corresponding model, the control main system of audio carries out exercises, finishes every performance checking.Because the display screen that the different model main system of audio is mated, the specification of guidance panel have nothing in common with each other, can not be general, not only need to drop into substantial contribution and buy corresponding display screen and guidance panel, if wherein a kind of model sound equipment stops production or transition, supporting checkout facility just can only discard, make manufacturing enterprise suffer bigger economic loss.
Summary of the invention
The utility model is in order to solve the above-mentioned technical problem of existing in prior technology, the automobile-used sound equipment emulation check system of a kind of highly versatile, cost saving to be provided.
Technical solution of the present utility model is: a kind of automobile-used sound equipment emulation check system, it is characterized in that: be provided with computer, be connected to mouse and display with computer, computer joins by RS232 signal processing circuit and anti-jamming circuit A, anti-jamming circuit B and TTL circuit, and anti-jamming circuit A and anti-jamming circuit B and CGI signal processor join.
The utility model is joined by RS232 signal processing circuit, anti-jamming circuit A, anti-jamming circuit B, TTL circuit and the CGI signal processor constitutes signal converter, can realize that tested vechicle is with communicating by letter between sound equipment and the serial ports of computers, can simulate equipment such as various automobile display screens, guidance panel by software, thereby control checks that sound equipment carries out exercises, demonstrates the various display message of sound equipment in real time realistically.This system's highly versatile, and test result is accurate, can save a large amount of procuring equipment funds, reduce quantity in stock, and manufacturing enterprise can not cause checkout facility to be scrapped because of certain sound equipment stops production or makes the transition, and avoids the waste that causes thus.
Description of drawings:
Fig. 1 is the schematic block circuit diagram of the utility model embodiment.
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1: be provided with computer (MAX3237E), be connected to mouse and display with computer, computer is by RS232 signal processing circuit and anti-jamming circuit A(SN74LVC1G17DCKR chip and peripheral circuit), anti-jamming circuit B(TC7SET08FU chip and peripheral circuit) and the TTL circuit join, anti-jamming circuit A and anti-jamming circuit B and CGI signal processor (PCA82C250) join.
During use, automobile audio and CGI signal processor and the TTL circuit of being produced joined.The operation mouse makes computer output control command, and order is passed through anti-jamming circuit B after handling by the RS232 signal processing circuit again, converts the executable procedure code of tested sound equipment to through the CGI signal processor; After sound equipment was carried out the requirement of control message, the result of generation was transmitted back to computer by CGI signal processor, anti-jamming circuit A and RS232 signal processing circuit; Computer then to the result who receives handle, computing, and the result shown on display screen; The TTL circuit is handled control signal, and it is unimpeded to guarantee to communicate by letter.
