The invention discloses a power consumption information collection system main station pressure test method and system based on virtual terminals. The power consumption information collection system main station pressure test method based on the virtual terminals comprises the following steps: building a virtual terminal for simulating a concentrator terminal, wherein the virtual terminal is usedto implement all functions of communication between an entity concentrator terminal and a main station; configuring N virtual terminals according to preset configuration parameters; establishing the communication between the main station and each virtual terminal of the N virtual terminals, and confirming whether the communication state and functions are normal or not according to a preset rule; and controlling the N virtual terminals to perform the pressure test on the main station according to the preset rule, and obtaining the pressure test results. According to the power consumption information collection system main station pressure test method and system based on the virtual terminals, the virtual terminals for simulating the concentrator terminals are set, a plurality of independentthreads are established through a server and a plurality of virtual terminals for the pressure test are configured as required; therefore, the problems of high cost and complicated connection are solved, automated operation of pressure test with different degrees set as required is realized, and the efficiency of the main station test is greatly improved.
