Abstract：In view of the limited wireless transmission distance in the current test and transmission scheme of explosion shock wave data,it is difficult to achieve long-distance real-time transmission.In this paper,a long-distance wireless transmission sys-tem based on high-speed serial port server is designed to realize the high-speed and reliable real-time transmission of explosion shock wave signal to the PC terminal outside the explosion field.In order to realize the continuous transparent transmission function of serial server without error code,a data receiving cache mode and data forwarding strategy are proposed.In order to realize high-speed and long-distance wireless transmission,pDDL900 with Ethernet communication interface is selected for wireless trans-mission,and the wireless transmission distance is tested several times by configuring transmission parameters.In order to adapt the speed of the serial port to the speed of the remote lower network port,the protection mechanism of the serial port receiving overflow is designed to improve transmission reliability.The test results show that the maximum baud rate of the serial port can reach 9 Mbps without error,the transmission distance can reach more than 4 km,and the transmission speed is 1 Mbps.It can improve the trans-mission speed and transmission distance,improve the stability and universality of the system.
