Description
技术领域
本发明涉及液压支架控制领域,特别涉及一种液压支架控制中用到的隔离耦合器。
背景技术
在液压支架控制系统中,液压支架的控制需要多个驱动器分别控制,在信号的传递和通信过程中,需要对不同电源供电的液压支架控制单元之间的通信设置电气隔离。现有技术中采用的光耦合器可以实现液压支架用的隔离耦合器,但光耦合器由于体积、功耗、传输速度等越来越不能满足实际应用的需求。

本发明的目的在于克服现有技术的不足,提供一种液压支架控制系统用的隔离耦合器,用于实现液压支架系统中不同供电电源供电的控制器件之间的隔离通信。
为了实现上述目的,本发明采用的技术方案为:一种隔离耦合器,包括单片机、第一磁耦隔离器、第二磁耦隔离器,所述的单片机分别与第一磁耦隔离器、第二磁耦隔离器通信连接。
还包括第一CAN收发器、第二CAN收发器,第一CAN收发器接收外界CAN信号经第一磁耦隔离器送入到单片机中,单片机经第二磁耦隔离器后将信号送入到第二CAN收发器,第二CAN收发器将信号送出。

本发明的优点在于:通过磁耦隔离器实现液压支架控制系统中不同供电电源之间的通信隔离,具备体积小、传输速率高、功耗小的优点。
附图说明
下面对本发明说明书各幅附图表达的内容及图中的标记作简要说明:
图1为本发明隔离耦合器结构原理图。
具体实施方式
下面对照附图,通过对最优实施例的描述,对本发明的具体实施方式作进一步详细的说明。
本实施例给出一种采用磁耦隔离器实现的隔离耦合器,用于液压支架控制装置中不同电源供电的控制设备之间的通信隔离。隔离耦合器包括壳体以及设置在壳体内隔离电路。在客体上分别设置有两个通信接口,由于在液压支架控制领域,需要进行电气隔离的其中一种情况即为不同电源供电的驱动器,驱动器之间需要电气隔离。
在需要隔离的通信的两个驱动器中,其中一个驱动器内的控制器输出CAN信号经第一CAN收发器送入到第一磁耦隔离器,经磁耦隔离器后送入到单片机,单片机进行处理放大等操作后经第二磁耦隔离器送入到第二CAN收发器后经另一个通信接口送出。每一个通信接口均通过CAN收发器、磁耦隔离器后送入到单片机中,这里CAN收发器、磁耦隔离器、通信接口即可在作为接收回路又可作为发送回路,其为双向通信器件,可以实现隔离器两端的驱动器之间信息的互相发送传输。通过单片机接收、、磁耦隔离、CAN收发器进行转发,从而实现液压支架系统的通信隔离。
隔离耦合器内的单片机的供电采用直流稳压电源,电源经隔离耦合器内的隔离DC/DC转换器后为单片机供电。
隔离耦合器的壳体上设置有内部与外部通信的接口,包括通信接口、电源接口,在隔离耦合器内设置电源双路DC/DC,即分别设置第一DC/DC模块、第二DC/DC模块,两个独立的电源输出经隔离耦合器的第一电源输入接口、第二输入接口后连接第一DC/DC模块、第二DC/DC模块,第一DC/DC模块连接第一电源输出接口;第二电源接口经第二DC/DC模块连接第二电源输出接口,第一输入接口引入电源经隔离DC/DC转换器后将电压转换为为单片机工作电压为单片机供电,从而在隔离耦合器中引入电源通道,本安电源的输出信号经隔离耦合器内隔离DC/DC转换器内隔离耦合器内供电的同时,经DC/DC模块转换成稳定的直流电为其它设备供电,减少了另外设计电源转换设备成本。
显然本发明具体实现并不受上述方式的限制,只要采用了本发明的方法构思和技术方案进行的各种非实质性的改进,均在本发明的保护范围之内。
