An upper computer of the simulation device is connected to a synchronous serial interface signal simulation apparatus and controls the synchronous serial interface signal simulation apparatus to transmit an analog data signal. The synchronous serial interface signal simulation apparatus is connected with an external assembly interconnection standard collection device, transmits a simulation data signal to the external assembly interconnection standard collection device, and receives a clock signal. A collection device upper computer is connected with the external assembly interconnection standard collection device, and receives a simulation collection data signal transmitted by the external assembly interconnection standard collection device. The simulation device comprises an FPGA module, a PCI bridge chip, an SSI drive chip, a voltage conversion chip, a PCI bus, a collection device connection interface, and a power module. The device solves a problem that a fault of the external assembly interconnection standard collection device of a synchronous serial interface signal is difficult to detect in actual production in a mode of simulating the synchronous serial interface signal.

Description

technical field [0001] The invention relates to a simulation device and a simulation detection method, more specifically to a simulation device and a simulation detection method for detecting synchronous serial signal faults. Background technique [0002] In recent years, in many industrial measurement control applications, the Peripheral Component Interconnection (PCI) acquisition device for Synchronous Serial Interface (SSI) signals has gradually become a widely used device. The device realizes the PCI acquisition of SSI signals, collects the sensor signals of various SSI interfaces to the industrial control computer, and uses the centralized acquisition of various sensors to perform feedback control on various external devices. However, in actual industrial applications, there is a real problem that when the sensor signal changes, the data collected by the computer is not updated in time. Since it is difficult to accurately control the sensor signal manually in reality, ...
