Abstract
The invention relates to an acoustic control camera, characterized by comprising a wireless microphone receiver and a voice identification control circuit composed of voice identification processing chips; the microphone receiver in the voice identification control circuit receives an acoustic signal and then subjects the acoustic signal to analog/digital conversion, the signal is converted to a digital sampling signal processible to digital chips, different command words are processed by a microprocessor in a video sampling processing display circuit of the camera, and a motor is controlled to execute the corresponding motions; the invention does not need a wired connection controlled and is not influenced by the factors like the number of connection wires and distance of the connection wires, the system has long service life, no accidental potential, easiness for mounting, convenient control, simple operation and saves cost of the entire monitor system.
Description
Technical field
The present invention relates to the video monitoring camera head, the particularly a kind of acoustic control cam that can discern user's voice command control camera action.
Technical background
Existing monitoring product comprises camera, digital video recorder, monitor etc., wherein in the camera function the most complete should belong to the fast ball-type camera of intelligence, need send instruction to it by string, the parallel port external controller of RS-485 or other types during its work, rotate zoom, focus on exercises such as aperture folding.It is on-the-spot that general camera is installed in monitoring, controller is then in Control Room, installation wiring is loaded down with trivial details, be subjected to wiring link what, wiring bigger apart from the influence of factors such as distance, when through walls, underground cable, very easily damage cable insulation, directly influence system useful life, and can bring accident potential.
Summary of the invention
Single and not enough at prior art, a kind of acoustic control cam that can discern user's voice command control camera action provided by the present invention.
Acoustic control cam of the present invention is achieved through the following technical solutions: acoustic control cam comprises the video acquisition processes and displays circuit that is made of CCD camera, agc circuit, microprocessor (MICOM), it is characterized in that: also comprise the speech recognition controlled circuit that is made of wireless Mike's receiver (MIC Receiver), voice recognition processing chip (Audio DSP IC).
After Mike's receiver in the described speech recognition controlled circuit receives voice signal, be converted into the signal of telecommunication, the signal of telecommunication of high frequency carrier is the signal of telecommunication of low frequency through the filtering carrier restoring, this signal of telecommunication is transferred to the voice recognition processing chip, its input receives the audio signal of input, converts it into the accessible digital sampled signal of digit chip by the mould in the TMS320C5402/number conversion functional circuit; By the speech identifying function circuit in the voice recognition processing chip TMS320C5402 voice signal is carried out the digital compression Code And Decode again; Then the digital speech entry signal after handling is analyzed, identify the control command of entry signal representative, and command word exported, for microprocessor processes, the command word that default program is exported according to the speech recognition controlled chip that receives in the microprocessor, and it is handled accordingly, output signal is to various motor driving controling circuits.
Administrative staff are at Control Room, facing to Mike's order of sounding; Receiver is received voice signal; Built-in voice recognition processing chip judges that this signal is the order that camera need be carried out, and handles accordingly if then voice signal is converted to digital electronic signal.
Owing to adopt the technical scheme of built-in speech recognition controlled circuit, to the sound " order " that the user sends, compile and decipher, drive various motor correct execution corresponding action, thereby replace peripheral control unit to reach the purpose of accurate control.The present invention does not need by the wired connection controller, be not subjected to the wiring link what, wiring apart from far and near, etc. the influence of factor, system's long service life, accident free hidden danger is easy to install, and has saved the cost of whole monitoring system, control is convenient, and is simple to operate.
Description of drawings
Fig. 1 is the block diagram of acoustic control cam system, and as Figure of abstract.
Embodiment
Below in conjunction with accompanying drawing the present invention is elaborated:
As shown in Figure 1, the present invention includes wireless Mike's receiver (MIC Receiver), voice recognition processing chip Audio DSPIC (TMS320C5402), microprocessor MICOM (NEC or Toshiba), comprise rotation, zoom, focus on, the video sampling treatment circuit display circuit of motor drive controller of aperture folding motor (Motor Controller IC) and camera connects according to figure.
The user sends voice command facing to wireless Mike in Control Room, the MIC Receiver of camera receives the reduction voice signal, send voice recognition processing chip Audio DSP IC (TMS320C5402) again to, this chip is made up of three parts, first is mould/number conversion part, its input receives the audio signal of input, and converts it into the accessible digital sampled signal of digit chip; Second portion is the speech recognition part, finishes in DSP, and its core is that voice signal is carried out the digital compression Code And Decode; Third part is, the digital speech entry signal after handling is analyzed, and identifies the control command of entry signal representative, and with command word output, for microprocessor processes.Default program is according to the command word of the speech recognition controlled chip output that receives in the microprocessor, and it is handled accordingly, and output signal is to motor driving controling circuit, thus the action of control camera.Can reproduce in conjunction with prior art according to scheme provided by the invention.
