Abstract
The utility model discloses an automatic test system for product lines of digital TV phone mainboards. The automatic test system comprises a PC host, a power divider, a phone mainboard, a serial port data wire and a serial port/serial port wire, wherein the PC host is connected with a broadcasting digital TV phone signal source through the serial port/serial port wire, the signal source is connected with the power divider through a system connector, the power divider is connected with the phone mainboard through a special cable, the phone mainboard is connected with a corresponding serial port of the PC host through the serial port data wire, software at the PC end controls the broadcasting digital television phone signal source to send out TV signals in specific waveband frequency point and specific power, and the playing states of the phone and the television can be read through the serial port to judge the test results. The automatic test system has the advantages of simple structure, high automation, simple operation procedures and capability of shortening test time, and improving efficiency and the like.
Description
Technical field
The utility model relates to the Auto-Test System that a kind of Digital Television cell phone mainboard produces line, relates in particular to a kind of multiport Auto-Test System of broadcast digital TV cell phone mainboard.
Background technology
Along with the communication technology and Development of Multimedia Technology, the use of broadcast digital TV mobile phone more and more widely, and the test that has a cell phone mainboard of broadcast digital TV function is the necessary link in the production process.The test of broadcast digital TV cell phone mainboard is mainly undertaken by the method for conduction test.Need the frequency of manual signalization emission source and power to be input to the TV signal amplitude of mobile phone with adjustment before each test, whether the SNR (signal to noise ratio) by judging mobile phone TV signal and the mode of BER (error rate) value come testing mobile phone mainboard working properly.The method complicated operation of this manual test produces line and expends time in longer.
Summary of the invention
Deficiency at traditional broadcast Digital Television cell phone mainboard production line test technology, the purpose of this utility model is to provide a kind of broadcast digital TV cell phone mainboard Auto-Test System, as long as the production test personnel of cell phone manufacturer carry out shirtsleeve operation, by computer software interface display intuitively, just can draw correct testing result.This automatic test approach is simple to operate, and response is quick, the production efficiency height.
A kind of Digital Television cell phone mainboard produces the Auto-Test System of line, comprise: the PC main frame, power splitter, cell phone mainboard, serial port data line, serial ports/Serial Port Line, described PC main frame links to each other with broadcast digital TV mobile phone signal source by serial ports or Serial Port Line, signal source is connected with power splitter by system connector, and power splitter links to each other with cell phone mainboard by the dedicated RF cable, and cell phone mainboard connects by the corresponding serial ports with PC of serial port data line again.The TV signal of specific band frequency and certain power is sent in PC end software control broadcast digital TV mobile phone signal source.
The utility model broadcast digital TV cell phone mainboard produces the automatic testing principle of line: suppose that signal generator to the cable power loss of mobile phone mainboard is-P
LDbm, the mainboard internal power consumption of allowing is-P
BDbm, expectation reaches signal power and is-P
EDbm, then the threshold power of the emission of signal generator is-P
C(P
C=-(P
E-P
L-P
B)) dbm, when signal generator with threshold power-P
CAfter transmitting, transmission begins to sweep platform and play command to cell phone mainboard by serial ports, if program is (for example 2 seconds) energy normal play video image in official hour, then test result is sent back to the PC end and show the PASS value on software, expression cell phone mainboard test passes by serial ports; Otherwise show the FAIL value, the expression test failure.

Fig. 2 is provided with schematic diagram for transmit Frequency Band Selection and its frequency and power parameter of the utility model;
Fig. 3 is the schematic diagram of the utility model final testing result loopback to PC end software.
The number in the figure explanation
1-PC main frame 2-power splitter 3-cell phone mainboard 4-serial port data line
5-serial ports/Serial Port Line 6-numeral TV signal source
Embodiment
How further specify the utility model below in conjunction with accompanying drawing realizes:
Embodiment
As shown in Figure 1, PC main frame 1 links to each other with broadcast figure TV signal source 6 by serial ports/Serial Port Line 5, signal source is connected with power splitter 2 by system connector, and power splitter links to each other with cell phone mainboard 3 by the dedicated RF cable, and cell phone mainboard connects by the corresponding serial ports with PC of serial port data line 4 again.The TV signal of specific band frequency and certain power is sent in PC end software control broadcast digital TV mobile phone signal source, PC end software sends instruction by serial ports and begins to sweep platform and broadcast to cell phone mainboard, according to program at the appointed time (for example 2 seconds) can normally receive criterion directly perceived with broadcast video signal, whether qualified, and test result is shown that loopback is to PC end software and showing if drawing cell phone mainboard test.
As shown in Figure 2, PC main frame 1 links to each other with broadcast figure TV signal source 6 by serial ports/Serial Port Line 5, after starting PC end software, program is downloaded to broadcast digital TV mobile phone signal source, select the frequency band signals of transmission, set the frequency and the power threshold of signal emission, emissioning testing signal is given cell phone mainboard then.
As shown in Figure 3, cell phone mainboard 3 is placed on the anchor clamps, link to each other by serial port data line 4 and PC main frame 1 corresponding serial ports, behind the emissioning testing signal of Digital Television mobile phone signal to be broadcast source, PC end software sends instruction to cell phone mainboard by serial ports, the test of first cell phone mainboard of beginning, after to be tested the finishing, send serial ports again and instruct, the test of second cell phone mainboard of beginning to second mainboard, successively class this, can finish the test of the cell phone mainboard of all serial ports correspondences on the PC.The order that PC sends instruction is to finish automatically, and the operator only needs to carry out the test that " test " this single action can be finished all mainboards on software interface.
