The data transmission mode is that the main controller sends data to the transmission module through the serial port, and the transmission module sends the data to the power supply product to be tested through the UART, the CAN, the RS485 or a wire harness, so that the end-to-end communication between the main controller and the product to be tested is realized.
The transparent transmission module is a transparent transmission module as the name implies, and the transparent transmission is that in the transmission process, no matter how the transmitted service is, only the service needing to be transmitted is transmitted to the destination node, which is equivalent to a data line or a serial port line, and the serial port data is transmitted to the product end through the transparent transmission module, but the transmitted service is not processed.
The data transfer process does not require the transmission of specific commands. Of course, the transmission mode is entered or the main controller is required to configure related commands sent by the transmission module, for example, the transmission rate, the transmission communication mode and the like. Care should be taken that: in the transparent transmission mode, information such as verification is preferably added to prevent communication problems such as packet loss, and the transparent transmission mode is required to be exited to check the problems when equipment communication is abnormal.
The communication of the specific product end in the market at present needs to select a proper communication adapter (for example, RS485 needs to be selected as the communication adapter of RS485, CAN needs to be selected as the communication adapter of CAN, UART selects as the communication adapter of UART) according to the communication interface of the product, a corresponding communication adapter driver is installed, and then the main control software invokes the driver to realize the communication between the product and the main control.
In the process, engineering personnel are required to have certain knowledge of various communication modes so as to be normally used, and even the engineering personnel cannot be used. Resulting in a decrease in the overall production efficiency, we need to propose a data transparent transmission device.
