Embodiment Construction

[0022] The principles and embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] Such as figure 1 As shown, the present invention sets up a circuit, the circuit has several detection nodes, and each detection node has a value of an electrical parameter that is different, so that the electrical parameter can be used as a unique identifier corresponding to the address of the module and / or device. In this embodiment, the circuit adopts a voltage divider circuit, and multiple resistors are connected in series with each other, and then a power supply is connected to the first and last ends of the resistor string to form multiple detection nodes with different voltage values. The voltage dividing circuit is not only simple in structure, but also the specific voltage value of the power supply is not limited, and can be selected according to the power supply situation of the module and / or device and the voltage de...

Abstract

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.

Description

technical field [0001] The invention relates to communication technology, in particular to a system and method for automatically assigning addresses. Background technique [0002] With the development of industrial manufacturing and new energy industries, controllers such as PLC and DDC in the field of industrial control are developing towards high integration, high functional density, and modularization. For example, in a factory energy management system, it may include a processor module, a gateway module, an information collection module, an actuator module, etc., and the modules usually transmit data, control and other information through communication. The communication methods are generally wired and wireless. The common ones for wired communication are RS485 and CAN, and the common ones for wireless communication are Lora and NB-IOT. [0003] Taking the physically connected data bus as an example, many devices are usually connected to a data bus, and the data of each...
