This process is very troublesome to complete manually. After the improvement, use pandas to enter the materials to be inquired from excel. Selenium completes the automated query of the inventory, processes the data, and puts the corresponding label and data. Deposited into excel; greatly improved efficiency through the use of selenium-Web Browser Automation automated test software; and also successfully applied to BOM management and entry, material application;* Use Python to simplify a lot of daily work; Show less

* Responsible for the hardware development of the 50K module UPS. Among them, it is responsible for the drawing some of the schematic, using saber to simulate the hardware circuit, assisting the layout engineer to draw the PCB, and then performing the board debugging. Machine test, after nearly one year of hard work, the product is finally closed, has been mass-produced, and has good feedback in the market;* Since 2017, I have been responsible for the maintenance of the inverter software… Show more * Responsible for the hardware development of the 50K module UPS.

Machine test, after nearly one year of hard work, the product is finally closed, has been mass-produced, and has good feedback in the market;* Since 2017, I have been responsible for the maintenance of the inverter software independently. I can use the simulink in matlab to simulate the control algorithm.From November 2017, the porting work of control software (using CCSV7) was carried out, and another colleague responsible for rectifier software worked together to migrate from the existing platform TI C2000 tms32f2808 to tms320f28377d. The transplant work has been completed. Among them, the TI C2000 series MCU has an in-depth understanding, and has a deeper understanding of CAN, SPI, SCI, I2C, shared memory communication and other communication methods;* Independently completed the preparation of a host computer software (using VS2017), realizing the multi-module online upgrade of the rectifier inverter bypass software, supporting up to 16 modules, the underlying communication is realized through the CAN bus; and the BootLoader function is realized, that is, Online upgrades can also be implemented without DSP internal programs;* The embedded Linux, application compiled by MakeFile (based on the embedded operating system) has been rewritten as CMake, which greatly increases the readability of the program; during this period, it is also familiar with the overall structure of u-boot; Show less
