According to the data communication requirements and high-voltage interference working conditions of the selfdeveloped high-voltage pulse electroporation therapeutic apparatus,the RS232 communication hardware circuit with anti-interference ability is designed and the data communication protocol is established to realize the instantaneous transmission of a large amount of data. It introduced the working principle of the high-voltage pulse electroporation therapeutic apparatus.In view of the high-voltage and strong interference working environment of the therapeutic apparatus,the actual requirements for the reliable transmission of the upper and lower computer data of the therapeutic instrument control system are analyzed. The hardware implementation scheme,data communication protocol,and data visualization implementation of the upper computer are designed. The communication test results prove that serial communication system designed works stably during large data volume communication,and the data transmission is accurate and reliable in the environment of high-voltage pulse interference to meet the requirements of the high-voltage pulse therapeutic apparatus.
