The invention discloses an ICD (
interface control document) designing method independent of a network. The ICD designing method independent of the network includes the following steps: a step 1: acquiring packaging rules of various network buses needing to be used; a step 2: inputting parameters and attribute information which need to be transmitted by a device to an
application layer ICD; a step3: selecting a network
bus needing to be used, and using the packaging rule corresponding to the network
bus to define the
application layer ICD; and a step 4: generating a
physical layer ICD file. The ICD designing method independent of the network starts with the device
application layer, analyzes differences of various network
bus protocols, and forms the packaging rules of various network buses, can automatically
package the application layer ICD through a
software tool, and can perform automatic conversion to acquire the
physical layer ICD. The method can improve the
usability of device interface data between cross-project types, can shorten the ICD designing time, and can greatly enhance the
readability of a device interaction relation.
