Abstract: The existing virtual simulation experiment system does not have an accurate human-computer interaction identification mechanism, which leads to poor signal receiving effect in the process of using virtual simulation equipment. In order to improve the stability of signal link, a virtual simulation experiment system based on sponge campus update is designed and developed. The hardware design of the system is completed by designing the circuit of the single-chip microcomputer system, setting up the coding structure of human-computer interaction, and connecting it to the connecting port of the triode. Through the establishment of campus space rain flood analysis module and sponge campus geographic data visualization module, the modular design of the system is completed. According to the hardware design and software design, the development of sponge campus renewal design virtual simulation experiment system is realized. In the experiment, compared with the last system design, the control rate of total runoff, the utilization rate of rainwater and the reduction rate of runoff pollutants of sponge campus renewal design virtual simulation experiment system are higher.
