Figure 8 As shown, the CC simulation cabinet also includes an onboard switch and an onboard fan, and the simulation main control board 3 of the CC simulation cabinet is respectively connected to the onboard switch and the onboard fan. The simulation cabinet has the functions of automatic identification number, control and status feedback.

[0044] The simulation cabinet also includes multiple communication extensions. The board 1 communicates with the extensions via the CAN bus. Each extension is configured with a different IP address. The board is connected to the TC7000-2S extension via the CAN bus. The TC7000-2S extension is then connected to the software simulation platform via a switch. The four extensions need to be configured with four different IP addresses.
