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.

In order to improve the convenience of upgrading the display program, the invention provides a portable burning device for burning the program for the display, wherein the display is provided with a video signal female socket and a main control chip electrically connected with the video signal female socket.

Referring to fig. 1, in an embodiment, the portable recording device provided by the present invention includes a memory, a signal connection male, a trigger component and a control circuit, wherein the control circuit is electrically connected to the memory, the signal connection male and the trigger component respectively.

The memory is used for storing the pre-burning program.

The signal connection male head is used for being connected with a video signal female seat of the display in a pluggable mode.

The trigger component is used for outputting a burning trigger signal when triggering.

The control circuit is used for reading the pre-burning program in the memory when receiving the burning trigger signal and burning the pre-burning program into a main control chip of the display connected with a video signal female seat of the display through a signal connection male head.

In this embodiment, the trigger component 30 may be a key, a toggle switch, or other devices, and when a maintainer needs to burn a program on a main control chip of a display, the maintainer may press the key or the toggle switch to enable the trigger component 30 to output a burning trigger signal, where the burning trigger signal may be a high level signal or a low level signal. After receiving the burning trigger signal, the control circuit 40 can communicate with the memory connected to the memory interface 10, read the data stored therein, and burn the data to the main control chip of the display through the signal connection male connector 20.

In this embodiment, the male signal connector 20 may be a VGA plug, a DP plug, or an HDMI plug, and is used for accessing a video signal female socket of a display.

In this embodiment, the control circuit 40 may be implemented by a main control chip, such as a main control chip of an MCU (microprogrammed control unit), a DSP (Digital Signal processing) chip, an FPGA (Field Programmable Gate Array) chip, or the like. The memory 10 may be a storage unit integrated inside a main control chip, and the main control chip may directly read a pre-burning program of the internal storage unit when receiving a burning trigger signal that is active at a high level or active at a low level. The memory 10 may also be a memory chip that is externally connected to the circuit board and electrically connected to the main control chip, so as to increase the storage capacity of the main control chip, such as a FLASH memory chip. When receiving a burning trigger signal with effective high level or effective low level, the main control chip establishes communication with the storage chip according to a certain communication protocol, such as an SPI communication protocol, a serial communication protocol, an I2C communication protocol, a USART communication protocol and the like, and then reads a pre-burning recording program stored in the storage chip.

In the burning process, the control circuit 40, for example, the main control chip, establishes communication with the main control chip of the display electrically connected to the video signal female socket of the display through the signal connection male connector according to a certain communication protocol, the type of which corresponds to a communication interface that the main control chip of the display can satisfy, for example, an SPI communication protocol, a serial communication protocol, an I2C communication protocol, USART communication, and the like. And after signal processing is carried out on the pre-burning program, the pre-burning program is burnt into a main control chip of the display so as to finish upgrading of the display program.

Specifically, referring to fig. 3, a chip of the display is taken as an MTK master chip for explanation. After receiving the burning trigger signal, the main control chip of the control circuit 40 establishes an I2C communication protocol with the MTK main chip by signal connection male header, video signal female socket, and then sends a signal to make the MTK main chip enter an ISP (In-System Programming) mode, after the MTK main chip successfully enters the ISP mode, the main control chip sends an instruction to read a Flash ID of the current MTK main chip, the Flash ID is a communication address of a storage unit inside the MTK main chip, after reading the Flash ID, the main control chip sends a corresponding command signal for removing the write protection and the erase according to the Flash ID, thereby erasing the program stored In the current storage unit before, and then, sending a white checking instruction signal, detecting whether the program in the storage unit in the MTK main chip is completely erased or not, and preventing the program which is not erased from influencing a new program when a subsequent burning program is carried out inwards. After the process is completed, the pre-burning program is written into the MTK main chip according to the requirement of a communication protocol, after the writing is completed, the verification is performed, whether a writing error occurs is checked, if the error occurs, the portable burning device can be further provided with a display component electrically connected with the main control chip, when the reading and writing error occurs, the main control chip can control the display component to prompt a user that the current burning error occurs while the burning is stopped, and after the verification is completed and the writing protection is started, the main control chip outputs an instruction of quitting the ISP mode to control the MTK main chip, so that the whole burning process is completed.

Meanwhile, the control circuit 40 of the present invention can directly read the pre-burning program in the memory 10 and then burn the pre-burning program into the main control chip of the display. Therefore, in practical application, when a maintainer burns, the burning operation does not need to be carried out through a computer and a burner of a main control chip corresponding to the display, a corresponding driving program does not need to be installed on the computer, and the program upgrading of the display can be realized only by connecting the portable burning device stored with the burning pre-burning program into a video signal female seat of the display through a signal connection male connector. The operation mode is simple, and the method can be suitable for maintenance personnel without an electronic foundation to operate.

In an embodiment of the invention, the portable burning apparatus further includes a memory interface, and the memory interface 80 is electrically connected to the control circuit 40. Wherein the memory interface 80 is used for accessing the external memory.

In this embodiment, the number of the memory interfaces 80 may be one or more, and the types of the plurality of memory interfaces 80 may not be uniform, such as a USB interface, an SATA interface, an m.2 interface, an ATA interface, and the like, and are used to plug in and pull out different types of external memories, such as an external memory of a USB disk, a mobile hard disk, a solid state disk, and the like.

In this embodiment, the control circuit may further establish electrical connection with the external memory and implement communication interaction when the external memory is accessed, and when the burning trigger signal is received, the control circuit reads the pre-burning program stored in the external memory and burns the pre-burning program into the main control chip of the display connected to the video signal female socket of the display through the signal connection male plug. Therefore, maintenance personnel can prepare different external memories respectively storing different versions in advance without recording programs in the memory of the portable recording device. Therefore, the burning of different types of displays is realized, or different programs are burned for the same type of display, the convenience of maintenance personnel in the burning work after sale is effectively improved, the preparation time and the switching time for burning different programs are reduced, and the burning efficiency of the programs for the display is improved.

Referring to fig. 2, in an embodiment of the invention, the portable recording device further includes a display element 50, and the display element 50 is electrically connected to the control circuit 40.

In this embodiment, the control circuit can control the display module to perform different displays according to the burning status. The display component can be a display screen, such as a TFT screen, a liquid crystal screen, an OLED screen, etc., and the control circuit can control the display screen to display a corresponding prompt character according to the burning process, for example, when the signal connection male plug is successfully inserted into the video signal female socket of the display, the control circuit can control the display screen to display a "connection successful" character. In the burning process, the control circuit can detect the current burning progress in real time and display the current burning progress on the display screen in the forms of burning progress bars, burning percentages, residual burning time and the like so as to prompt the current burning progress of a user. When the burning fails, the control circuit can also control the display screen to display 'burning failure' and prompt the reason of the burning failure, so that a user can know the current burning fault condition conveniently.

In addition, in another embodiment, the display component may further use a lamp component and a sound component, such as an LED lamp, a buzzer, etc., the LED lamp may be selected from red and green, when the portable recording device is successfully connected to the video signal female socket of the display, the green lamp may be displayed to prompt the user that the current connection is successful, and the portable recording device is in a to-be-recorded state, when recording is started, the red and green lamps may alternately flash to prompt the user that the recording is currently being performed, and when recording is successful, the green lamp is returned to be normally on. If the burning fails in midway, the red light is controlled to be normally on, and the buzzer is started to prompt the user that the burning fails.

Through the arrangement, when the maintainer uses the current equipment to burn, the maintainer can intuitively know the current burning state, so that the maintainer can conveniently arrange and insert the current fault condition when the burning fails, and the use convenience of the portable burning device is improved.

In another embodiment, the control circuit 40 is further configured to detect the data amount of the pre-burning program in the memory when receiving the burning trigger signal, and stop burning and control the display module 50 to output a warning signal indicating that the burning fails when detecting that the data amount of the pre-burning program in the memory is greater than a preset data amount.

It should be understood that, in the actual post-maintenance and upgrade process, the states of the main control chips of different display motherboards may be different, and the internal storage amount may also be changed by the current state of the storage chip, for example, a small part inside the main control chip is damaged, which may result in a reduction in the storage amount. Therefore, when the pre-burning program is burned into the main control chip of the display mainboard, the pre-burning program may be larger than the capacity of the main control chip of the display mainboard. If the maintainer directly performs the burning, the failure of the burning may be prompted after waiting for a period of time, for example, 30S is required for normal burning, and the failure of the burning may be prompted when an excessively large program reaches 25S, which causes waste of burning time and reduces burning efficiency.

Specifically, when the control circuit 40 receives the burning trigger signal, if the pre-burning program is stored in a memory, such as a memory integrated inside the main control chip, the main control chip can directly read the data size of the current pre-burning program; if the memory is an external memory on the circuit board, or the pre-burning program is stored in the external memory, and the external memory is inserted into the memory interface, the control circuit can output a data quantity inquiry signal to the external memory. When receiving the data amount inquiry signal, the external memory detects the data amount of the pre-burning program and outputs a corresponding data amount signal to the control circuit 40. And the control circuit 40 stops burning and controls the display component 50 to display that the capacity of the current memory chip is insufficient when the data size of the pre-burning program is larger than a preset storage value according to the data volume signal. The preset storage value is the size of the data size which can be stored by the display main control chip. Therefore, the burning device can compare the size of the program before the program in the memory is read, so that the problem that the burning time is wasted by maintenance personnel due to the fact that the size of the main control chip of the display is not enough is avoided, and the burning efficiency of the program of the display main board is improved.

Referring to FIG. 2, in an embodiment of the invention, the portable recording device further includes a protection circuit 60, an input terminal of the protection circuit 60 is connected to an output terminal of the control circuit 40, and an output terminal of the protection circuit 60 is electrically connected to the signal connection male 20.

The buffer may adopt an output buffer register, and can temporarily store the output pre-burn-in program, so that the clocks between the control circuit 40 and the main control chip of the display motherboard are unified, synchronization of data transmission is realized, and the transmission stability of the pre-burn-in program is improved. The amplitude limiting circuit can adopt an amplitude limiter which can set an amplitude limiting upper limit value, so that signals transmitted to a main control chip of the display by the control circuit 40 due to static electricity are prevented, namely the situation that the amplitude of a pre-burning program is increased occurs, and the antistatic capacity of the whole portable burning device is effectively improved.

Through the arrangement, the whole anti-interference capability of the portable burning device can be improved, the control circuit 40 can stably and accurately write the pre-burning program pre-stored in the memory into the main control chip of the current display mainboard, the anti-interference performance and the stability of the work of the whole portable burning device are improved, and the burning efficiency and the stability of the program of the display mainboard are further improved.

It should be understood that, in actual circuit operation, the voltage provided by the external power supply, such as the 12V voltage of the USB power supply output, may be higher than the upper limit of the operating voltage that can be borne by the main control chip in the current control circuit or other components in the portable burning device, such as the lamp, the buzzer, and the like.
