The invention will be further explained by the description of the embodiments with reference to the drawings.
The embodiment provides an automatic television testing method, as shown in fig. 1, the method includes:
s10, when the television receives the appointed infrared signal wave band in the starting-up stage, the original program signal is converted into a VBO signal;
and S20, when the television executes the initialization of the VBO signal output, sending the data to be tested to the external detection equipment through the VBO signal, and realizing the automatic test of the running state of the television.
In this embodiment, a signal receiver capable of recognizing and receiving a designated infrared signal band is disposed in the television, the designated infrared signal band is not used for a common television, when the television in this embodiment receives the designated infrared signal band at a power-on stage, a default original program signal may be forcibly converted into a VBO signal, VBO (V-by-OneHS) is a signal transmission interface standard developed by heine electronics corporation (thineeectronics) and applied to a display, and a current maximum speed may reach 3.75G, which is a technology similar to TMDS adopted by HDMI. The VBO signal is mainly applied to data communication of a flat-panel television, and has the advantages that CLK (clock) is superposed on the data signal and transmitted in a common mode, so that a CLK signal line can be omitted compared with HDMI, and the requirement on a transmission wire is low because the transmission distance is usually short. The VBO signal usually adopts AC coupling, which means that a capacitor is connected in series between a signal transmitting end and a signal receiving end, so that a DC component of the signal is isolated, a cutoff frequency depends on the size of the coupling capacitor, an AC component of a low-frequency signal is also blocked and greatly attenuated, but an AC component of a high-frequency signal can still well pass through, so that the high-speed serial VBO signal generally adopts an AC coupling mode.
In this embodiment, because the VBO signal belongs to an open source interface protocol, when the television sends data to be tested to the external detection device through the VBO signal, the external detection device can directly receive, identify and analyze the VBO signal, so as to verify the whole process of television operation, whether each function is normal or not, that is, to implement automatic test on the television operation state. The method and the device can effectively shorten the testing time of the running state of the television, improve the overall process efficiency and reduce the cost of using hardware equipment.
In some embodiments, as shown in fig. 2, the step S10, when the television receives the designated infrared signal in the power-on stage, the converting the original program signal into the VBO signal specifically includes:
s11, when the television is in the starting stage, monitoring the external infrared signal within the preset distance range in real time;
s12, when the external infrared signal is monitored to be in the appointed infrared signal wave band, converting the original program signal into a VBO signal;
and S13, initializing according to the original program signal when the external infrared signal is not monitored to be in the designated infrared signal wave band.
In this embodiment, because the effective receiving distance of the receiver for receiving the infrared signal inside the television is limited, the receiver can monitor the external infrared signal within a predetermined distance range in real time, compare the monitored external infrared signal with the specified infrared signal band, if the comparison finds that the band of the external infrared signal is within the specified infrared signal band range, it indicates that the external detection device has sent a signal conversion instruction to the television, at this time, the television forcibly converts the original program signal into a VBO signal according to the received instruction, if the comparison finds that the band of the external infrared signal is not within the specified infrared signal band range, it indicates that the external detection device has not sent the signal conversion instruction, and at this time, the television is initialized according to the default original program signal.
In some embodiments, the designated infrared signal band may be a less frequently used far infrared band, such as, but not limited to, the 200-.
In some embodiments, the default original program signal within the television is typically a non-open source data protocol, e.g., the original program signal is an epi signal.
In some embodiments, the data to be tested is one or more of image data, television screen parameter data, and television channel data, but is not limited thereto.
In some embodiments, when the television outputs the data to be detected from the terminal through the VBO signal, the external detection device may be connected to the television through a physical screen line, and after the external detection device obtains the data to be detected, the external detection device analyzes and matches the data to be detected through a software algorithm, so that whether the current running state of the television is correct or not can be known. In some preferred embodiments, the television can be further in communication connection with an external detection device in a bluetooth, wifi, infrared or serial port manner, so that automatic testing of the television is realized, that is, the television is controlled, and data to be tested is analyzed according to the obtained VBO signal. In some specific embodiments, it can be determined whether the tv can switch to the corresponding tv channel, such as atv, dtmb, hdim, etc., by analyzing the data to be tested. Through analyzing the data to be detected, whether the television has a black screen, a flower screen and snowflake points or not can be judged, whether the built-in application of the intelligent television can be skipped or not, whether the startup is normal or not can be judged.
The embodiment also provides a television automatic testing method, wherein as shown in fig. 3, the method comprises the following steps:
s100, when detecting that an original program signal of the television is a non-open source data protocol, sending a specified infrared signal wave band to the television;
s200, the television sends the data to be detected to external detection equipment through a VBO signal;
s300, when the external detection equipment receives the data to be tested sent by the television, analyzing the data to be tested, and realizing the automatic test of the running state of the television.
In the embodiment, a television is in communication connection with external detection equipment in advance, and when the television is in a starting-up stage and a screen drive is not initialized, the type of an original program signal of the television is detected; if the original program signal of the television is detected to be an open source data protocol, the appointed infrared signal wave band is not sent to the television; if the original program signal of the television is detected to be an open source data protocol, a specified infrared signal wave band is sent to the television; after the television receives the appointed infrared signal wave band, the original program signal is converted into a VBO signal, the data to be detected is sent to external detection equipment through the VBO signal, and when the external detection equipment receives the data to be detected sent by the television, the data to be detected is analyzed, so that the automatic test of the running state of the television is realized.
