Abstract:
1. A device for aligning an antenna, comprising a receiving unit, a practically received power value acquiring unit, an alignment judging unit, an antenna adjusting unit, and an alignment indicating unit, wherein the receiving unit is adapted to receive an input signal, and output a receiver signal strength indication (RSSI) value according to a strength of the input signal; the practically received power value acquiring unit is adapted to receive the RSSI value, and acquire a practically received power value corresponding to the input signal by looking up a corresponding table between RSSI and power; the alignment judging unit is adapted to compare the practically received power value with a theoretically received power threshold value, output an antenna rotation signal to the antenna adjusting unit when the practically received power value is smaller than the theoretically received power threshold value, and output an alignment indication signal to the alignment indicating unit when the practically received power value is greater than or equal to the theoretically received power threshold value; the antenna adjusting unit is adapted to adjust the antenna according to the antenna rotation signal so as to change a receiving angle of the antenna; the alignment indicating unit is adapted to display that the antenna is aligned according to the alignment indication signal; the alignment judging unit further comprises an extreme value determining module adapted to use a maximum value of the practically received power value during an adjustment process as an extreme value when the practically receive power value is greater than or equal to the theoretically received power threshold value and output a first extreme value signal to the antenna adjusting unit; the antenna adjusting unit is further adapted to fix a position of the antenna according to the first extreme value signal; the extreme value determining module is further adapted to output the first extreme value signal to the receiving unit; and the receiving unit is further adapted to send through the antenna an alignment output signal to a peer end antenna according to the first extreme value signal, the alignment output signal used to adjust an alignment position of the peer end antenna.
