In control communication layer, there is not a more comprehensive and uniform standards for intelligent building control on the market, which led to the emergence of a flourishing state of the market. During the existing programs in the market, the hardware is controlled through either the Wi-Fi signal corps or a bus directly, which inevitably takes lots of inconvenience in diversely demanded society. In this paper, based on embedded systems, for the integration issues of intelligent building control, the Wi-Fi collaborates with the bus to realize the building controlled concurrently and orderly, at the same time, in order to avoid actually state, signal lights achieve synchronization and mutual exclusion. Ultimately achieve concurrency, atomicity dimmer speed hardware control.
