System and method for automatically assigning addresses

The present invention discloses a system and method for automatically assigning addresses, wherein the system for automatically assigning addresses comprises: a plurality of interconnected devices and/or modules, and a circuit having a plurality of detecting nodes, wherein values of certain electrical parameters of the respective detecting nodes are different, and the devices and/or modules are respectively access to different detection nodes, the value of the electrical parameter is used as the unique identifier of an address of the device and/or module, to automatically obtain the address. The system is simple to implement, and can automatically acquire the address of the device and/or the module after accessing the system, thereby eliminating trouble of manual operation. 本发明公开了种自动分配地址的系统及方法，其中自动分配地址的系统包括若干个相互连接的设备和/或模块、具有若干个检测节点的电路，所述各个检测节点的某电参数的值均不相同，所述各设备和/或模块分别接入到不同的检测节点，以电参数的值作为其地址的唯标识，来自动获取地址。本发明实现简单，可以使设备和/或模块接入系统以后，自动获取其地址，免去了人工操作的麻烦。
