A method for wireless automatic networking includes: pre-selecting N frequencies for frequency-hopping, if a relay node requires frequency hopping, then transmitting a beacon to routing nodes, if the routing nodes do not receive the beacon, then the routing nodes hop frequencies, search, and track until the beacon is received; work frequencies of the relay node, of the routing nodes, and of a terminal node are established in a shared channel; then, insofar as the transmit powers of the nodes are optimized, each routing node is tested for the presence of a frequency conflict with other routing nodes; if found, then frequencies are reassigned to the conflicting routing nodes until none of the frequencies of the routing nodes overlap each other; the relay node sequentially loads the frequencies of the routing nodes, and when frequency loading is completed for all of the routing nodes, a network enters a normal working state.

The present invention discloses an apparatus and method capable of automatically identifying an obstacle in front of a mobile terminal, the apparatus comprising a transmitting module, a receiving module, and a controller MCU module. The transmitting module is in signal connection to the receiving module, the transmitting module and the receiving module are both in signal connection to the controller MCU module (STM32 series), and the controller MCU module is also in signal connection to a mobile terminal CPU. The present invention may automatically identify the road condition in front of the mobile terminal and may carry out a voice prompt in time.
