The embedded communication system of underwater glider based on QNX

In this paper, introduced the characteristics of microkernel architecture of QNX on which the underwater glider was built, and then, aimed at the special function requests, on detailed analysis of underwater glider communication system combined with design concept of multi communication models based on QNX, the main design method of structure and functions of communication system in underwater glider were described clearly. Moreover, the realization process of united interrupt and query serial communication model were given as well as the Ethernet model. Especially, the unique interprocess communication model of public data block of atomic level with automic and voliatile types was expounded. Experiments showed the communication effect was perfect.
