The invention discloses a dual-system communication method and a computer readable storage medium. The method comprises the steps: building a first communication channel in a first operation system when a first system task on the first operation system needs to communicate with a second system task on a second operation system; writing the filter number corresponding to the second system task intothe shared memory by the second system task; the first communication channel acquires a filter number from the shared memory; the first system task writes the communication data and the address and the length thereof into a first communication channel; the first communication channel sends the communication data and the address and the length of the communication data to a filter corresponding tothe filter number for filtering verification; if the verification is passed, copying the communication data into a data block in a shared memory, and adding the serial number of the data block into afirst queue; and the secon
