This invention is related to automatic monitoring and collaboration among aircrafts. Specifically, an aircraft receives the current and future state of adjacent aircrafts by broadcast, then analyzes the start time of collaborative tasks. Base on the start time and prior knowledge, it adjusts automatically the prediction accuracy requirements of its future states, the check interval of predicted state errors and the minimum check interval. And it makes a new prediction and broadcasts new future states based on the check results of prediction errors. In the invention, an aircraft does not periodically broadcast its states, but broadcasts irregularly its future states according to its current tasks, its states and surrounding environment. The invention guarantees that collaborative tasks can be can be correctly carried out among aircrafts while it reduces the bandwidth requirement of wireless communication. It provides guarantee of high density flight and collaboration among many aircrafts.

A multi-disk fault-tolerant system, a method for generating a check block, and a method for recovering a data block are provided. The multi-disk fault-tolerant system includes a disk array and a calculation module connected through a system bus, the disk array is formed by p disks, and a fault-tolerant disk amount of the disk array is q; data in the disk array is arranged according to a form of a matrix M of (m+q)&#xd7;p, where m is a prime number smaller than or equal to p&#x2212;q; in the matrix M, a 0row is virtual data blocks being virtual and having values being 0, a 1row to an (m&#x2212;1)row are data blocks, an mrow to an (m+q&#x2212;1)row are check blocks. Therefore, during a procedure of generating the check block and recovering the data block in the multi-disk fault-tolerant system, calculation complexity is lowered.
