The signal wireless transmission system used during the television debugging process covers the radio frequency signals in the debugging area, and the radio frequency signal wireless receiving end is inserted in the television to be detected so as to receive the signals, so that signal wires are not needed, the debugging efficiency is improved effectively, and the debugging process can be schemed flexibly.
Description
Technical field the utility model relates to a kind of debug system, relates in particular to the signal wireless transmission system in a kind of television set debugging process.
The all television sets of background technology are equipped with wireless radio interface (also being RF (Radio Frequency) interface), and it belongs to analog signal interface, and closed circuit signaling transmits into TV by this interface.In the debug process of television set, need be in television set input signal, whether clear to detect television set at the operational mode hypograph, have or not asterism, smear etc. unusual, detect sound and be as good as sound, resonance etc. unusually, and whether detect the TV menu function normal.In the prior art, the debugging of television set is that the mode with streamline is distributed in a plurality of function debuggings station, and signal is to import television set to be measured by holding wire by wireless radio interface.In debug process, the operator in each function debugging station manually inserts holding wire the wireless radio interface of television set to be measured, after debugging, manually pulls out holding wire by operator again, and television set to be measured then enters next function debugging station.
There is following shortcoming in prior art:
1, whenever carry out a debugging, all need operator that holding wire is plugged, the time has been wasted in repetitive operation, has reduced the production debugging efficiency.
2, for large-sized television set, its shell sizes is big, operator plug holding wire difficulty, and easy scratch television rear shell.
3, the frock plate that is loaded with television set flow to tune-up center and stable after, operator just can insert holding wire, has caused the waste of stand-by period.
4, need lay holding wire in advance according to the layout of streamline length, tune-up center, in a single day streamline builds up the back and is difficult to add new debugging erect-position again.
The summary of the invention the purpose of this utility model provides a kind of holding wire that need not to arrange, effectively improves debugging efficiency, can arrange the signal wireless transmission system in the television set debugging process of television set debugging flow process flexibly.
For achieving the above object, the utility model signal wireless transmission system comprises radiofrequency signal wireless transmitting terminals and radiofrequency signal wireless interface receiving end; Described radiofrequency signal wireless transmitting terminals comprises signal generator, modulator, frequency mixer, amplifier and transmitting antenna, the signal of described signal generator output becomes the standard frequency through connected modulators modulate, after the blender mixing, amplify the radiofrequency signal of generation by the transmission antennas transmit that is positioned at terminal by amplifier again; The radiofrequency signal of described radiofrequency signal wireless transmitting terminals emission can cover the television set debugging zone; Described radiofrequency signal wireless interface receiving end comprises the less radio-frequency joint and the reception antenna that with this less radio-frequency joint be connected suitable with television set less radio-frequency socket; Described radiofrequency signal wireless receiving termination is received the radiofrequency signal of radiofrequency signal wireless transmitting terminals emission, and is converted into corresponding image and sound in the input television set.
The utility model adopts said system, be coated with radiofrequency signal in the television set debugging zone of production line, television set receives this radiofrequency signal by the less radio-frequency receiving terminal, makes television set produce corresponding image and sound, so just need not arrange holding wire in the debugging zone.In debug process, only need before television set to be measured enters debugging production line, on the less radio-frequency socket of television set to be measured, to insert radiofrequency signal wireless interface receiving end; Through after all debug-items, pull out radiofrequency signal wireless interface receiving end by operator again, thereby avoided operator Plug Action repeatedly, improved debugging efficiency, also avoided unexpected damaged products.Simultaneously, owing to all be coated with radiofrequency signal in the whole debugging zone, welcome arrangement is gone into new debugging erect-position or is carried out other and adjust flexibly in the debugging zone.
The transmitting antenna of radiofrequency signal wireless transmitting terminals of the present utility model evenly is arranged in the debugging zone.Make so all to be coated with radiofrequency signal in the whole debugging zone and intensity is even, guaranteed carrying out smoothly of debug process.
The radiofrequency signal of radiofrequency signal wireless transmitting terminals emission of the present utility model is video and audio mix signal, makes TV function to be measured carry out the whole debug-items relevant with video and audio frequency, has guaranteed the quality of product.
The signal of being received by radiofrequency signal wireless receiving termination is called in TV function of the present utility model remote control, makes its operator need not manual operation or close board, has guaranteed the safety of operator, has improved the quality of product, has also improved debugging efficiency.
In sum, the utility model compared with prior art, the utility model covers radiofrequency signal by the radiofrequency signal wireless transmitting terminals in the debugging zone, on television set to be measured, insert radiofrequency signal wireless receiving termination and receive this signal, thereby need not to arrange holding wire, effectively improve debugging efficiency, and can arrange to debug flow process flexibly.
