Abstract

The invention discloses a software testing device for an escalator printing plate. The software testing device comprises a relay output module, an IO input board card, an IO output board card, a pulse output board card, a CAN communication board card, an RS232 communication board card, a relay and a testing system. The test system is connected with the relay output module, the IO input board card, the IO output board card, the pulse output board card, the CAN communication board card and the RS232 communication board card. The IO input board card is connected with the relay, and a level output signal of an escalator printing plate is transferred by the relay and then is input into the IO input board card; the IO output board card and the relay output module are connected with the relay, and level output signals of the IO output board card and the relay output module are transferred through the relay and then input into an escalator printing plate level input interface. And the pulse output board card is connected with a pulse input interface of the escalator printing plate. All external interfaces of an escalator hardware system can be replaced, more functions and scenes are covered, and the automation degree of software testing is improved.
