The invention discloses a buffer circuit-based high-precision
wireless voice recognition
access control system, which mainly consists of a
central processing unit, a second
wireless transmission module, an A / D (analog to digital) switching circuit, an
access control driving circuit, an alarm module, a display module, a memory, a first
wireless transmission module, a
frequency stabilization circuit, a sound sensor, an
access control, a
signal processing circuit, a PC (
personal computer) and the like, wherein the A / D switching circuit, the access control
driving circuit, the alarm module, the display module, the memory and the first
wireless transmission module are respectively connected with the
central processing unit; the
frequency stabilization circuit is connected with the A / D switching circuit; the sound sensor is connected with the
frequency stabilization circuit; the access control is connected with the access control
driving circuit; the
signal processing circuit is connected with the second
wireless transmission module; the PC is connected with the
signal processing circuit. According to the buffer circuit-based high-precision wireless voice recognition access
control system disclosed by the invention,
data transmission is performed by adopting a wireless manner to realize access control and the
information exchange of the PC, therefore the construction difficulty is reduced, and an administrator is helped to transform an access
control network in the future; the buffer circuit-based high-precision wireless voice recognition access
control system disclosed by the invention is provided with a buffer circuit; the buffer circuit can be used for smoothly inputting a signal into the
central processing unit, so that the phenomenon that
signal processing and recognition of the central processing unit is influenced by signal fluctuation is avoided, and the recognition precision of the buffer circuit-based high-precision wireless voice recognition access
control system disclosed by the invention is improved.
