摘要（英）：

The invention discloses a multipath signal generating simulator with a storage function, comprising a computer which is electrically connected with a signal generating simulator (1) by RS232. The core element of the signal generating simulator (1) is MCU, the periphery of which is provided with at least two RS232 interfaces, at least two CAN interfaces, at least two FPGAs and at least one storage. Both the FPGA and the CAN are provided with an external interface. The FPGA comprises a data buffering and locking circuit, a decoder, a VEM bus simulator and a square wave signal generator. The invention can simplify the testing device, is convenient to take and use on site, decreases the manufacturing cost and is applied to the scientific research department, the producing enterprise and the service department for electric locomotive and internal combustion locomotive.
