背景技术:
见图1、图2所示,一般电子换向驱动电机包括电机实体和电机控制器,电机实体包括电机的定子和转子部分,电机控制器除了需要与电机实体匹配外,还需要与电机具体的应用系统一即用户端控制系统的控制接口匹配,因为不同的用户端控制系统匹配不同的控制信号,例如空调控制系统与洗衣机控制系统都是用户端的控制系统,两个系统的控制信号完全不一样。传统的做法是针对每一种用户端控制系统就开发一种电机及电机控制器,这样一来产生如下问题:1)电机厂家生产的电机型号非常多,不便于管理和标准化;2)浪费开发时间和研发的投入,因为每一个新的用户端控制系统都需要重新开发一款电机,增加产品的制造成本;3)重新设计需要制定新的生产工艺和认证成本,增加了投入;4)电机应用范围非常窄,不便于大范围推广应用。
为了解决上述的技术问题,现在出现了一些子母线路板对接的电机控制器,将电机控制器的主要功能电路设置在母线路板上,将多种的接口单元电路和身份识别电路设置在多个子线路板上,利用其中一个子线路板与母线路板对接,子线路板上的身份识别电路通知母线路板上的微处理器单元,由微处理器单元自动配置子线路板上的I/O口类型,从而可以通过更换不同的子线路板就可以应用不同场合,应用范围广,电机生产厂家减少电机的种类便于管理,可以减少电机的研发投入、缩短研发周期,降低产品成本,简化生产工艺,提高效率。
其具体的技术方案如图3、图4和图5所示,电机控制器包括微处理器单元、信号接口单元和身份识别电路,微处理器单元设置在母线路板上,信号接口单元、身份识别电路设置在子线路板上,通过子线路板和母线路板的对接形成电连接,身份识别电路将识别信号输入到微处理器单元,微处理器单元根据识别信号自动配置信号接口单元的各个I/o端口的类型。不同种类的信号接口单 元匹配的身份识别电路输出不同的信号,形成多个不同的子线路板。微处理器单元的输出端连接功率逆变单元,转子位置检测单元的输出端连接微处理器单元的输入端,功率逆变单元和转子位置检测单元都设置在母线路板上。电源电路和模拟量检测单元也设置在母线路板上,模拟量检测单元主要检测主板上的母线电流、母线电压、相电流和NTC等模拟量信息。电源电路为各部份电路供电。所述的微处理器单元是CPU或者是单片机MCU或者是数字信号处理器DSP。母线路板上设置接插端口3,接插端口3里面设置11路接线片,子线路板可以有多个,接插端口3上11路接线片分别为E、N、L、M1、M2、M3、M4、M5、M6、M7、M8,各接线片的可以按如下标准定义,E、N、L三路是电源输入,M1、M2、M3、M4、M5、M6、M7、M8是用户端控制系统输入到子线路板的接口信号。在母线路板上设置有插槽1,子线路板上设置有插接头2,插接头2嵌套在插槽1里面,使子线路板与母线路板电连接起来。
在实际应用中存在如下缺点:1)母线路板上的微处理器单元要处理子线路板上多路电路信号,负荷过重,降低其工作运行效率,同时母线路板上的微处理器单元存储空间较小,难以满足日益增加的数据量;2)接口信号存在高压信号控制,子线路板与母线路板之间需要采用多路电气隔离,电路复杂,成本高。
