[0060] In yet another embodiment, please refer to again Figure 2 As shown, taking the dual-channel TCON version information and current test as an example, this embodiment provides another TCON board detection device, which mainly solves the following technical problems: (1) Controlling the operation of the entire device by communicating with the host computer, including data communication and 12V power supply for the product; (2) Adding a current detection module to ensure that there is no problem in the first test of the overall circuit when the version information of the product is correct; (3) Adding a verification module for verifying the version information and current value; For the convenience of understanding, the technical terms used are explained as follows:

[0061] FPGA: (Field-Programmable Gate Array) Field Programmable Gate Array

[0062] uart_rxd: Serial port receive data line, used for the slave device to receive data sent from the master device;

[0063] uart_txd: Serial port transmit data line, used for the slave device to send data to the master device;

[0064] cm_command: Command information sent from the master device to the slave device, which is the data after serial-to-parallel conversion by the uart_rxd serial port receive data line;

[0065] current_inf: Data information sent from the slave device to the master device, which needs to be sent out by the uart_txd serial port transmit data line after parallel-to-serial conversion;

[0066] IIC_SCL1, IIC_SDA1: IIC bus of the product to be detected on the first channel, used to read the version information of the first channel;

[0067] IIC_CSCL1, IIC_CSDA1: IIC bus of the current monitoring chip on the first channel, used to read the current value of the first channel;

[0068] IIC_SCL2, IIC_SDA2: IIC bus of the product to be detected on the second channel, used to read the version information of the second channel;

[0070] SCL1, SDA1: IIC bus of the product to be detected on the first channel, used to control the opening or closing of the first channel;

[0071] SCL2, SDA2: IIC bus of the product to be detected on the second channel, used to control the opening or closing of the second channel;

[0072] BYTE: Byte is a measurement unit used by computer information technology to measure storage capacity;

[0073] ROM: Read-Only Memory, read-only memory;

[0074] CRC: Cyclic Redundancy Check, which is to calculate a set of check codes based on data and is used to check whether the data is changed or transmitted incorrectly during the data transmission process;

[0075] MOS: Abbreviation of MOSFET, metal-oxide-semiconductor field-effect transistor.

[0076] Specifically, the device consists of the following five parts:

[0077] The first part is the serial communication module: (1) After the barcode scanning device sends the information of the product to be detected at channel 1 or channel 2 to the host computer, the host computer sends a detection command to the serial communication module of the FPGA through the uart_rxd data line. The serial communication module performs serial-to-parallel conversion on the detection command to obtain cm_command, and performs CRC check on the cm_command command. After successful check, the IIC switching control module and the TCON board power supply module of the corresponding channel are enabled according to the transmission information in cm_command. Table 1 below is an example of cm_command. The 3rd byte data in the cm_command command represents the detection channel, 00 represents channel 1, and 01 represents channel 2; the 6th byte data in the cm_command command represents the product number, and the product number corresponds to the IIC device address of the product and the register address for storing the version information. (2) The serial communication module also receives the current_inf data from the calibration module, performs parallel-to-serial conversion on the current_inf and sends it to the host computer through uart_txd.

[0078] Table 1 Example of cm_command

[0079] Example of cm_command Command Detect the first product on Channel 1 XX XX 00 02 00 01CRC XX XX Detect the second product on Channel 1 XX XX 00 02 00 02CRC XX XX Detect the fourth product on Channel 2 XX XX 01 02 00 04CRC XX XX Detect the sixth product on Channel 2 XX XX 01 02 00 06CRC XX XX

[0080] The second part is the IIC switching control module: Please refer to Figure 3 As shown, (1) The IIC switching control module parses the cm_command command. When the 3rd byte data in the cm_command command is 00, the IIC switching control chip 1 is turned on, and at the same time, according to the 6th byte data in the cm_command command, the version information and current value of the products corresponding to channels 1 and 2 to be detected are read; similarly, when the 3rd byte data in the cm_command command is 01, the IIC switching control chip 2 is turned on, and data reading operations are performed on channels 3 and 4. (2) After the reading is completed, the IIC switching control chip will be turned off and turned on again when there is the next product to be detected. At the same time, the IIC switching control module will pass the read version information data and current data into the FPGA calibration module.

[0081] The third part is the calibration module: (1) The calibration module will store the version information data of different products in different ROMs in advance, and select the corresponding numbered ROM according to the 6th byte data in the cm_command command. (2) Such as Figure 4As shown in the figure, the version information and current value transmitted by the IIC switching control module are compared. After the verification is completed, the data is packaged. If the data verification is correct, the correct version information and OK flag are returned; otherwise, the NG flag is returned. Table 2 below is an example of current_inf, where the 8th and 9th bytes represent the version information, the 10th and 11th bytes represent the current value. The current value in hexadecimal is 12AB, and the actual current value is 4.779 mA. The 12th and 13th bytes represent the NG or OK flag, where 00 00 represents OK and 00 FF represents NG.

[0082] Table 2 Example of current_inf

[0083] Example of current_inf Command Detect the first product on Channel 1, OK XX XX 00 02 00 01CRC 00 14 12AB 00 00XX XX Detect the second product on Channel 2, NG XX XX 00 02 00 02CRC FF FF 13 48 00FF XX XX

[0084] Part 4: TCON board power supply module: The TCON board power supply module uses MOS transistors and triodes to perform the on-off operation of the 12V voltage, and controls the power supply of different channels according to the cm_command command information.

[0085] Part 5: LCD liquid crystal display screen: After the verification module completes the verification, the LCD liquid crystal control screen module receives the current_inf data and displays the test situation of the channel on the LCD liquid crystal display screen.

[0086] The following describes the process of TCON board detection in combination with the interaction between the above five parts:

[0087] (1) The serial communication module communicates with the host computer through uart_rxd and uart_txd. At the same time, the parsed cm_command is transmitted to the FPGA main chip, and the current_inf to be sent by the FPGA main chip can also be serially converted and sent out through the serial port.

[0088] (2) The verification module consists of a ROM and verification logic. The ROM form stores the version information of the TCON product and the maximum and minimum ranges of the current value; the verification logic traverses the corresponding ROM form by identifying the product information contained in the cm_command, and at the same time compares the values in the ROM form with the obtained version information and current value, and packages the comparison results into current_inf.

[0089] (3) The LCD liquid crystal display screen module is used to display whether the dual-channel product test is NG or OK, and at the same time display the current test status.

[0090] (4) The IIC switching control module works using IIC control logic. First, it conducts or cuts off the corresponding IIC channels according to the channel information in cm_command. Second, it communicates with the TCON product to be detected and the current monitoring chip, reads the version information and current value therein, and transfers the values to the calibration module.

[0091] (5) The TCON board power supply control module supplies power to the corresponding channels according to the cm_command command received by the FPGA main chip, enabling the product to be detected to work.

[0092] The above TCON board detection device has at least the following beneficial technical effects: adopting a dual-channel test method, doubling the speed compared to the single-channel test method; at the same time, adopting a communication method with the host computer, eliminating manual operations, improving the test accuracy, and adding a current test function, which can test the performance of the TCON board in advance and can be combined with mechanical equipment for automated testing.

[0093] In another embodiment, please refer to Figure 5 As shown, the present invention also provides a TCON board detection method. The method uses the above-mentioned TCON board detection device. The TCON board detection method includes:

[0096] Step 3, using the verification module to match the parsed model with the preset version information and model correspondence relationship to determine the target version information, and comparing the current version information with the target version information to generate a version comparison result and send it to the main control chip;

[0097] Step 4, the main control chip returns the version comparison result to the host computer.

[0098] The above TCON board detection method uses the main control chip to communicate with the TCON board to be detected and the host computer respectively, and then uses the verification module to proofread the version information according to the information provided by the host computer to generate a version comparison result, and finally returns the version comparison result to the host computer, realizing the automatic detection of the version information of the TCON board, improving the detection accuracy, without manual adjustment and discrimination, and greatly saving labor costs.
