The invention discloses a drive test data collecting system and method. The method comprises the following steps that S1) an X86 platform sends a frequency spectrum scanning instruction, and sends the instruction to an intermediate-frequency board via an Ethernet command; S2) a DSP of the intermediate-frequency board parses the instruction, and an FPGA is started to implement signal collection; S3) the FPGA carries out AD collection, DDC and FFT operation simultaneously; S4) data is returned to the DSP of the intermediate-frequency board and packaged, and then sent to the X86 platform via the Ethernet; S5) the X86 platform extracts points from the FFT frequency spectrum, and stores the extracted points in a hard disk according to protocols; S6) a WIFI reading instruction is waited for; and S7) a WIFI reading module reads stored data according to the WIFI reading instruction, and returns the read data to terminal equipment for analysis. According to the invention, the electromagnetic environment in a monitoring area can be investigated generally in a regular or irregular manner, drive test data of a mobile monitoring station is collected, and technical and data support is provided for station checking and managing.
