Description

一种具有联网通讯功能的BLDC电机及电器设备 技术领域
本发明涉及一种具有联网通讯功能的BLDC电机及电器设备。
背景技术
现在，为实现一台电气设备(主机)控制多台BLDC电机(从机)，经常选用抗干扰能力强和可高速通讯的485通讯设计，但一控多，需要多台BLDC电机有着各自完全不同的地址选择。其中多台BLDC电机各自的地址必须是唯一的，不然会造成整个通讯系统的紊乱。
为实现多台BLDC电机的不同地址以供主机和从机进行互相识别。分别有如下3种技术方案；
(1)在电机控制器中设置拨码电路设置，在出厂前或安装前将几台设备的拨码调到各自不同的位置，通过芯片识别对其分配不同的地址。见专利号为：CN202010281701.2、名称为一种MODBUS网卡的发明专利。
(2)地址软件固化，在出厂前对设备编写不同的程序，程序的不同点在于设置的地址不一样。控制几台电机，就有几款程序。
(3)利用可读取存储设置，在485通讯网络中，对每一个设备发送带有地址的通讯代码，设备在接收后将其存储在自己的可读取存储结构中。完成多台设备的地址控制。
但是，从以上的描述中来看，我们能明显看到其各个技术的缺点：
(1)第一个技术方案的缺点为；需要在出厂前就设置好各自的地址状态，即每一台控制器的地址都需要标识处理，而且若客户端后续需要更改地址，则需要拆下设备并拆开到控制器模块再去手动更改拨码。
(2)第二个技术方案的缺点为；需要在出厂前给控制模块分配不同的软件，还需要做好标识处理，并且在客户端的时候将无法手动更改地址。
(3)第三个技术方案的缺点为，整个系统不够可靠，如果哪个地址分配出现错误将会导致整个系统的错乱。或者是某个设备损坏进行更换，其地址并不会沿用他之前的地址，这种情况下整个系统也会紊乱。

具体实施方式
下面通过具体实施例并结合附图对本发明作进一步详细的描述。
实施例一：
