Embodiment

[0055]A visual analog indoor walkie-talkie controlled by a single chip in this embodiment includes a power input conversion module, a main control module, an audio input and output module, a video signal amplification module, and an LCD driver module. The power input conversion module, audio input The output module, the video signal amplification module and the LCD driver module are all connected with the main control module.

[0056] The power input conversion module is used to convert the DC-12V / 24V input voltage into stable DC-9V and DC-5V voltages;

[0057] The main control module is used to control audio and video playback and intercom functions, and realize communication and menu setting functions;

[0058] The audio input and output module is used to convert the PWM signal from the main control module into a ring tone audio signal and play it, filter and amplify the intercom audio signal input from the outside and play it, and collect the weak audio signal collected by ...

Abstract

The invention discloses a visible analog indoor intercom controlled by a single chip and a control method. The visible analog indoor intercom comprises a power supply input conversion module, a main control module, an audio input and output module, a video signal amplification module and an LCD driving module, wherein the power supply input conversion module, the audio input and output module, the video signal amplification module and the LCD driving module are connected to the main control module. According to the invention, system communication and control and a video display function can be achieved by one chip, and due to the high integration property, the wiring of a circuit board can be simplified, the area of the circuit board can be decreased, the parts and components can be saved, and the production procedures can be saved, so that the development difficulty and the production cost of the products are reduced.

Description

technical field [0001] The invention relates to the research field of walkie-talkies, in particular to a visual analog indoor walkie-talkie controlled by a single chip and a control method. Background technique [0002] At present, in people's daily life, if the traditional analog video indoor intercom used in the home or office needs to realize video display, it usually requires the system main control chip to cooperate with a separate video playback module. Among them, the main control chip of the system is used to realize functions such as system communication and system work control. The separate video playback module is connected to the main board through a cable, controlled by the main control chip, and is specially used to process analog video signals and drive the LCD screen to display images. Due to the use of independent modules, the difficulty of circuit design and production costs will be increased to a certain extent, and the process in the production process wi...
