Description

一种车载负载电源控制系统 技术领域
本发明涉及车载系统设计技术领域，具体涉及一种车载负载电源控制系统。
背景技术
汽车的飞速发展，汽车电子日新月异，汽车电子逐步趋于高智能化、高性能化、高功率化。但目前车载电源无法完全满足这“三高”，也限制了汽车电子的发展。市场上也涌现了许许多多关于车载电源监控的发明及设备，用于优化电源，但还是存在诸多缺陷，无法真正满足客户需求。例如：有的出现异常无警报；有的汽车点火时，因为电源供电不足，无法启动汽车，而监控系统不会自动关闭负载；有的不能与外部主机进行通信，实行必要性升级修改等等。这些也脱离了我们现实生活的“三高”最求，造成很多不便，技术方面还有很大的改进空间，尤其是在车载负载电源控制系统方面有待进一步的改进。
发明内容
针对上述现有技术的不足本发明提供一种使用方便、便于维护、性能稳定的车载负载电源控制系统。
为了解决上述技术问题，本发明所采取的技术方案为：
本发明提供一种车载负载电源控制系统，包括电源输入模块、信号检测模块、CPU处理模块、电源输出控制模块、通信模块、异常警报模块、过载保护模块和电源输出端，所述电源输入模块连接有车载电源，所述通信模块连接有外部主机，所述电源输入模块用于将所述车载电源进行稳压滤波处理后，给所述CPU处理模块及所述电源输出控制模块供电，所述信号检测模块连接汽车点火开关ACC负载开关，所述信号检测模块用于检测负载开关及汽车点火开关ACC1的状态信息，并将所述状态信息传输给所述CPU处理模块处理与控制，所述CPU处理模块用于分析得到的各种信息，对并电源输出控制模块进行监控，所述电源输出控制模块按照所述CPU处理模块发送的指令对电源输入和输出进行监控，所述通信模块用于连接所述CPU处理模块和所述外部主机的通信，并修改所述CPU处理模块的控制模式或者输出所述CPU处理模块检测到的信息， 所述过载保护模块用于预防所述负载异常发生过载，所述异常报警模块对所述CPU处理模块检测到的各种异常进行警报。
进一步地，所述负载开关包括第一负载开关和第二负载开关。
进一步地，所述过载保护模块包括第一过载保护模块和第一过载保护模块。
进一步地，所述电源输出端包括第一电源输出端和第二电源输出端。
本发明所提供的一种车载负载电源控制系统有益效果：
本发明所提供的一种车载负载电源控制系统采用多端口选择性输出，异步控制技术，与外部主机实现通信，拥有多种异常报警模式，便于故障检查维护，使用成本较低，性能稳定，使用起来极为方便。
附图说明
图1是本发明所提供的一种车载负载电源控制系统的工作原理图。
具体实施方式
下面结合附图具体阐明本发明的实施方式，附图仅供参考和说明使用，不构成对本发明专利保护范围的限制。
如图1所示，本发明提供一种车载负载电源控制系统，包括电源输入模块1、信号检测模块2、CPU处理模块3、电源输出控制模块4、通信模块5、异常警报模块6、过载保护模块7和电源输出端8，所述电源输入模块1连接有车载电源9，所述通信模块5连接有外部主机10，所述电源输入模块1用于将所述车载电源进行稳压滤波处理后，给所述CPU处理模块3及所述电源输出控制模块供电，所述信号检测模块2连接汽车点火开关ACC11和负载开关12，所述信号检测模块用于检测负载开关及汽车点火开关ACC11的状态信息，并将所述状态信息传输给所述CPU处理模块3处理与控制，所述CPU处理模块3用于分析得到的各种信息，对并电源输出控制模块4进行监控，所述电源输出控制模块4按照所述CPU处理模块3发送的指令对电源输入和输出进行监控，所述通信模块5用于连接所述CPU处理模块3和所述外部主机的通信，并修改所述CPU处理模块3的控制模式或者输出所述CPU处理模块3检测到的信息，所述过载保护模块7用于预防所述负载异常发生过载，所述异常报警模块6对所述CPU处理模块3检测到的各种异常进行警报。
本实施例中所述负载开关12包括第一负载开关121和第二负载开关122。
本实施例中所述过载保护模块7包括第一过载保护模块71和第一过载保护模块72。
本实施例中所述电源输出端8包括第一电源输出端81和第二电源输出端82。
本发明提供一种车载负载电源控制系统具有如下特点：
(1)多端口选择性输出，异步控制
电源输出端由负载开关发出的信号进行控制，第一负载开关关闭对应第一输出端有电源输出,第一负载开关关闭打开，对应第一电源输出端无电源输出。避免了单个输出端口接线不方便，或多输出端口只能同步操作，无法异步控制的情况。
(2)自动处理电压异常
CPU处理模块5每个运作周期都会检测车载电源、汽车点火开关ACC、用户控制的负载开关的状态信息，如果车载电源的电压不在检测范围内，则发生异常。如果CPU处理模块还可以正常工作则启动车载电源异常模式，系统将关闭所有电源输出，启动声光警报；
如果ACC异常，如：汽车无法点火启动；中途熄火，但多次点火不成功。则启动ACC异常模式，系统将通过电源输出控制关闭所有电源输出，启动声光警报，保证正常电压点火。等点火成功后，关闭声光警报，再按照负载开关进行开启相关电源输出；
如果负载开关发生异常，如：开关不断被波动，则启动负载开关异常模式，关闭异常开关控制的电源输出端，启动声光警报。直至开关正常维持一定时间后关闭声光警报，再开启对应电源输出端，保护负载；
三个异常存在优先级，车载电源异常的优先级最高，其次是ACC异常，最低级的是负载开关异常。
(3)与外部主机实现通信
制定相关的通信协议模板、信息传出模板，只要套用相关的模板，就可以获取CPU处理模块检测到的信息，也可对CPU处理模块进行控制模式修改，这便于整个设备的升级、维护与修理。
(4)多种异常报警模式，便于故障检查维护
目前设置有三种异常模式，我们可以通过各种模式光、声进行警报，一切正常，灯光灭4.5秒亮0.5秒，不进行声音警报，车载电源异常模式：灯光0.5亮，0.5秒灭快速闪动，声报车载电源异常，ACC异常模式：灯光0.5亮，0.5秒灭快速闪动，声报ACC异常，负载开关异常模式：灯光1亮，2秒灭快速闪动，声报负载开关异常，这样，只要看提示灯的状况或听声音警报，我们就能很快找出异常的原因，有目的地进行检查、维护。
本发明提供一种车载负载电源控制系统中CPU处理模块先对信号检测模块回馈的信号分析，判断车载电源电压是否在规定的范围内、汽车点火开关ACC是否能正常成功点火、各负载开关状态。如果出现异常则通过电源输出控制模块关闭电源输出，启动异常警报模块发出相对应的声光警告，如果正常，则电源输出控制模块根据负载开关情况开启相对应的电源端口，输出电压，如果负载出现短路等异常，使设备输出超过负载范围，在过载保护将自动打开，保护设备及负载，如果需要改变CPU处理器的控制状态(如反应时间、监控电压方位等)或输出相关检测信息，只需要通过通信模块和外部主机进行通信设置即可完成，不需要对整体改造。
本发明所提供的一种车载负载电源控制系统采用多端口选择性输出，异步控制技术，与外部主机实现通信，拥有多种异常报警模式，便于故障检查维护，使用成本较低，性能稳定，使用起来极为方便。
以上所揭露的仅为本发明的较佳实施例，不能以此来限定本发明的权利保护范围，因此依本发明申请专利范围所作的等同变化，仍属本发明所涵盖的范围。
