The invention belongs to a touching-type simulator for a store management system, which is used during ground power-on check of a helicopter avionics system. The simulator comprises a DC/DC conversion module (1), a touch screen (2), a PC 104 module (3), an ARINC 429 communication board (4), an RS 422 communication board (5) and a KVM external member (6). The simulator can simulate ARINC 429 and RS 422 signals of various external store devices crosslinked with a store management unit, receive ARINC 429 and RS 422 signals from the store management unit, and can replace various external store devices and special testers to participate in the ground power-on test of the system.
