Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a first embodiment of a television detection system according to the present invention, where the television detection system includes: radio frequency signal transmitter 301, controller 302, camera 303 and transmitter 304.
The radio frequency signal transmitter 301 is configured to generate a detection radio frequency signal with a first level value according to a first detection command sent by the controller 302 when receiving the first detection command, and send the detection radio frequency signal to a television to be detected, so that the television to be detected displays a first picture according to the detection radio frequency signal.
It should be noted that the first detection command may be a first detection command generated by the controller when the user inputs the detection instruction into the controller, or may be a first detection command generated by the controller according to the detection process, which is not limited in the present invention.
Specifically, in the application, the television to be detected can be a digital television or a digital set top box, and when the equipment to be detected is the digital set top box, a display or the television which normally operates is required to receive a signal output by the set top box so as to display the first picture. The radio frequency signal transmitter may be an R & S BTC radio frequency signal transmitter, or may be another type of radio frequency signal transmitter, and the present invention is not limited in particular. The controller may be a PC or other type of computer, and the invention is not limited thereto.
In addition, the controller may be connected to the rf signal transmitter through a network cable to implement data transmission, and the transmission protocol is determined according to the type of the controller and the type of the rf signal transmitter, which is not limited in the present invention. In order to make the detection result more accurate, the first level value is preferably set lower.
Further, the radio frequency signal transmitter 301 is further configured to, before generating a detection radio frequency signal with a first level value according to the first detection command when receiving the first detection command sent by the controller, generate a detection radio frequency signal with a preset level value according to a third detection command sent by the controller when receiving the third detection command, and send the detection radio frequency signal with the preset level value to the to-be-detected television set, so that the to-be-detected television set displays a second picture according to the detection radio frequency signal with the preset level value;
the controller 302 is further configured to, when a second display state of the to-be-detected television for displaying the second picture is acquired from the camera 303, determine whether the second display state meets a second preset condition, and generate a first detection command when the second display state meets the second preset condition;
the radio frequency signal transmitter 301 is further configured to generate a detection radio frequency signal having a first level value according to the first detection command and the detection radio frequency signal having a preset level value when receiving the first detection command sent by the controller, where the preset level value is greater than the first level value.
It should be noted that the third detection command may be a detection command generated by the controller according to a detection operation input by the user, and the user may be a detection operation input through a voice input module, a keyboard input module, and the like of the controller, which is not limited in the present invention. The preset level value may be a standard level value, that is, the television may display a normal picture according to the detected radio frequency signal of the preset level value, that is, a picture of a first preset condition, where the first preset condition may be that no static frame exists in the picture, no black screen exists in the picture, no mosaic exists in the picture, and the present invention is not particularly limited.
In a specific application, the frequency of the detection rf signal with the preset level value generated by the rf signal transmitter is the same as the frequency of the detection rf signal with the first level value, and when detecting the television to be detected, it needs to be ensured that the detection rf signal is unchanged in the monitoring process, and meanwhile, the detection rf signal may include a typical channel model, a noise model, an interference model, and the like, where the present invention is not particularly limited.
In addition, the frequency setting and level value setting standard for detecting the radio frequency signal may be based on "GB/T26685 ground Digital Television receiver measurement method" or "D-Book 12Digital Television telecommunication Requirements for interoperability", or may be based on other Digital Television radio frequency performance receiving standards, and the present invention is not particularly limited.
In order to ensure that the television to be detected displays a picture meeting the second preset condition according to the detection radio frequency signal of the preset level value on the premise of no fault, the preset level value needs a higher value, and a user can set the preset level value according to the own requirement, which is not limited by the invention. The second preset condition may be that no static frame exists in the picture, no black screen exists in the picture, no mosaic exists in the picture, and the present invention is not particularly limited.
For example, based on the example of the 'GB/T26685 terrestrial digital television receiver measurement method' radio frequency signal with frequency point 658MHz, it is preset that the detection radio frequency signal with level value and the detection radio frequency signal with first level value are both radio frequency signals with frequency point 658 MHz.
Further, the controller 302 is further configured to control the transmitter 304 to send a stored preset search instruction to the to-be-detected television set when the second display state does not satisfy the second preset condition, so that the to-be-detected television set displays a third picture according to the preset search instruction and the detected radio frequency signal with the preset level value, where a third display state of the third display picture satisfies the second preset condition; and generating a first detection command according to the third display state when the third display state that the third picture is displayed by the television to be detected is acquired.
It should be noted that, when the to-be-detected television receives the detection radio frequency signal with the preset level value, the to-be-detected television cannot automatically perform program search, and the controller is required to control the transmitter to transmit the stored preset search instruction to the to-be-detected television, so that the to-be-detected television displays the third picture. It can be understood that the detected rf signal with the preset level value has a relatively high intensity, and the to-be-detected television can display a picture meeting the second preset condition after program search on the premise that the to-be-detected television does not have a fault.
It can be understood that, here, the purpose of generating the detection radio frequency signal with the preset level value is to transmit the detection radio frequency signal with the preset level value through the radio frequency signal transmitter, and the frequency point of the detection radio frequency signal is a frequency point which can be received by the television to be detected, so that the television to be detected and the television detection system operate normally, and the television to be detected displays a picture meeting a second preset condition, so as to continue to generate the detection radio frequency signal with the first level value according to the detection radio frequency signal with the preset level value and the third detection radio frequency signal; the situation that the preset level value is high enough, but the display state of the display picture does not meet the second preset condition due to the fact that the to-be-detected television does not carry out searching operation, and then the television detection system cannot continue to operate is avoided. The first level value is lower than the preset level value, and the detection radio frequency signal with the first level value and the detection radio frequency signal with the preset level value have the same frequency point.
In a specific application, the transmitter may be an infrared transmitter or a bluetooth transmitter, and the present invention is not limited thereto.
For example, the controller is connected with the R & S BTC through a network protocol, and the R & S BTC is connected with the tuner of the television to be detected through a coaxial cable. The controller sends a third detection command, the R & S BTC generates and sends a detection radio frequency signal with a 658MHz preset level value according to the received third detection command, and the television to be detected receives the detection radio frequency signal; the controller controls the transmitter (for example, a USB transmitting infrared television remote controller) to transmit a stored preset search instruction to the television to be detected, wherein the preset search instruction can be 'signal source' → 'ground digital television' → 'setting' → 'channel searching' → 'manual searching' → 'input 6, 5, 8' → 'determination' and the like, so that the television to be detected displays a picture meeting a second preset condition according to the received detection radio frequency signal of the preset multi-search instruction and the preset level value of the 658MHz frequency point; the controller sends a first detection instruction, and the R & S BTC generates a detection radio frequency signal with an A level value according to the received first detection instruction, a detection radio frequency signal with a preset level value and the first detection instruction, wherein the A level value is lower than the preset level value, and the A value is a minimum level value set by a user according to requirements.
Further, the controller 302 is further configured to control the transmitter 304 to generate and store a preset search instruction when a search operation is received before the stored preset search instruction is sent to the to-be-detected television by the transmitter 304 when the second display state does not satisfy the second preset condition.
In this case, the transmitter or the controller may receive the search operation. The search operation may be a search operation of pressing a number key such as "1", "2", "3", a "ok" key, a "back" key, an "up", "down", "left", "right", and a "signal source" key, which is sent by the user through the remote controller, and the present invention is not limited.
It can be understood that, when different televisions to be detected receive radio frequency signals with preset level values, the search processes performed may be different, and the preset search instructions sent by the transmitter are different accordingly, so that the user may input corresponding search operations according to the corresponding televisions to be detected, so that the transmitter generates and stores the corresponding preset search instructions.
The controller 302 is configured to, when the first display state that the to-be-detected television displays the first picture is acquired from the camera 303, determine whether the first display state meets a first preset condition, and determine the first level value as the lowest level value of the to-be-detected television when the first display state meets the first preset condition.
The camera of the invention can be a high-definition camera and can also be a common camera. The camera shoots a picture of the television to be detected to obtain a video stream including a picture display state, the controller obtains the video stream, obtains the display state according to the video stream, and judges whether the display state meets a first preset condition. And when the display state meets a first preset condition, determining the first level value as the lowest level value of the television to be detected.
For example, the controller is connected with the R & S BTC through a network protocol, and the R & S BTC is connected with the tuner of the television to be detected through a coaxial cable. The controller sends a third detection command, the R & S BTC generates and sends a detection radio frequency signal with a 658MHz preset level value according to the received third detection command, and the television to be detected receives the detection radio frequency signal; the controller controls the transmitter (for example, a USB transmitting infrared television remote controller) to transmit a stored preset search instruction to the television to be detected, wherein the preset search instruction can be 'signal source' → 'ground digital television' → 'setting' → 'channel searching' → 'manual searching' → 'input 6, 5, 8' → 'determination' and the like, so that the television to be detected displays a picture meeting a second preset condition according to the received detection radio frequency signal of the preset multi-search instruction and the preset level value of the 658MHz frequency point; the controller sends a first detection instruction, and the R & S BTC generates a detection radio frequency signal with an A level value according to the received first detection instruction, a detection radio frequency signal with a preset level value and the first detection instruction, wherein the A level value is lower than the preset level value, and the A value is a minimum level value set by a user according to requirements; the television to be detected displays a first display picture according to the received detection radio frequency signal of the A level value, the controller acquires video stream of the first picture shot by the camera from the camera, obtains a first display state of the first picture from the video stream, judges that the first display state meets a first preset condition, and at the moment, determines the A level value as a lowest level value.
Further, the controller 302 is further configured to determine whether the first display state meets the first preset condition within a preset time when the first display state of the first picture displayed by the to-be-detected television is acquired from the camera 303.
In order to determine whether the detected radio frequency signal of the current level value meets a first preset condition and can be stably displayed, whether the first preset condition is met all the time within a preset time needs to be set; the preset time can be 1 minute, the invention is not limited, and the user can set the time according to the requirement.
For example, the controller is connected with the R & S BTC through a network protocol, and the R & S BTC is connected with the tuner of the television to be detected through a coaxial cable. The controller sends a third detection command, the R & S BTC generates and sends a detection radio frequency signal with a 658MHz preset level value according to the received third detection command, and the television to be detected receives the detection radio frequency signal; the controller controls the transmitter (for example, a USB transmitting infrared television remote controller) to transmit a stored preset search instruction to the television to be detected, wherein the preset search instruction can be 'signal source' → 'ground digital television' → 'setting' → 'channel searching' → 'manual searching' → 'input 6, 5, 8' → 'determination' and the like, so that the television to be detected displays a picture meeting a second preset condition according to the received detection radio frequency signal of the preset multi-search instruction and the preset level value of the 658MHz frequency point; the controller sends a first detection instruction, and the R & S BTC generates a detection radio frequency signal with an A level value according to the received first detection instruction, a detection radio frequency signal with a preset level value and the first detection instruction, wherein the A level value is lower than the preset level value, and the A value is a minimum level value set by a user according to requirements; the television to be detected displays a first display picture according to the received detection radio frequency signal of the A level value, the controller acquires video stream of the first picture shot by the camera from the camera, obtains a first display state of the first picture from the video stream, judges that the first display state meets a first preset condition within one minute, and determines the A level value as a lowest level value.
Further, the controller 302 is further configured to generate a second detection command when the first display state does not satisfy the first preset condition;
the radio frequency signal transmitter 301 is further configured to generate a detection radio frequency signal with a new first level value according to the second detection command when receiving the second detection command sent by the controller 302, and send the detection radio frequency signal to the to-be-detected television, so that the to-be-detected television displays a first picture according to the detection radio frequency signal, where the new first level value is greater than the first level value.
It should be noted that, when the first display state does not satisfy the first preset condition, the first level value is lower, and the picture displayed by the television to be detected cannot satisfy the first preset condition. The detection radio frequency signal with a higher level value, namely the detection radio frequency signal with a new first level value, needs to be generated and is continuously judged by the controller, the television to be detected displays the first display state of the new first picture according to the detection radio frequency signal with the new first level value, whether the first display state meets the first preset condition or not is judged, and the level value at the moment is determined to be the lowest level value until the first display state meets the preset condition.
It will be appreciated that the emphasis of the change in the rf signal is the level value, and the generation of the new rf signal is essentially a level adjustment of the rf signal, i.e. the rf signal with the first level value and the rf signal with the new first level value are the same in frequency and different in level.
In a specific application, in order to ensure the detection accuracy of the level value, the adjustment value of the level value may be incremented by 0.05dBm each time the detection rf signal generated is compared with the detection rf signal generated last time, where 0.05dBm is a better adjustment value and does not form a limitation of the present invention.
