The invention discloses a vehicle voice alarm system based on platform area centralized control, which comprises an interactive display module, a voice warning control module and a sound production module, and is characterized in that the voice warning control module comprises a CAN transceiver, a switch acquisition module and an MCU controller, the CAN transceiver is used for inputting a whole vehicle digital signal. the switch acquisition module is used for carrying out A/D conversion on received physical signals of the whole vehicle and then inputting the signals into the MCU controller, the MCU controller is used for controlling the frequency and the duty ratio of PWM signals output by the PWM pin according to digital signals input by the CAN transceiver and the switch acquisition module, and the PWM pin of the MCU controller is connected with the sound production module to control the sound production module to produce sound. The MCU controller is connected with the interaction display module and used for information interaction control. According to the vehicle voice alarm system based on platform area centralized control, the MCU controller is used for collecting the whole vehicle demand signal, voice warning corresponding to the whole vehicle is controlled in a centralized mode, the number of modules and wire harness loops are reduced, and the cost and weight of the whole vehicle are reduced.
本发明公开了一种基于平台化区域集中控制的车辆语音报警系统,其包括:交互显示模块、语音警示控制模块和发声模块,语音警示控制模块包括CAN收发器、开关采集模块和MCU控制器,CAN收发器用于输入整车数字信号,开关采集模块用于对接收的整车物理信号进行A/D转化后,输入MCU控制器,MCU控制器用于根据CAN收发器和开关采集模块输入的数字信号,控制PWM引脚输出PWM信号的频率和占空比,MCU控制器的PWM引脚与发声模块连接,以控制发声模块发声,MCU控制器与交互显示模块连接,用于进行信息交互控制。本发明的基于平台化区域集中控制的车辆语音报警系统,通过MCU控制器采集整车需求信号,集中控制整车对应的语音警示,减少模块数量及线束回路,降低整车成本和重量。
