Problems solved by technology

However, no matter whether you use the DIP switch or set it separately with the smart man-machine terminal, you cannot allow other devices to receive the same setting information.
In practical engineering applications, if the equipment is installed in a place that is easily accessible to debuggers, it is not difficult to set the address separately. It is very inconvenient, and it is usually required to complete the bus debugging (including address setting) before packaging, which brings great restrictions and constraints to the project schedule

Embodiment Construction

[0067] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be more thoroughly understood, and will fully convey the scope of the present disclosure to those skilled in the art.

[0068] The inventors found that, in an IoT system, using a DIP switch or an intelligent human-machine terminal to set the address individually will be affected by the installation location of the equipment, which is very inconvenient, and will bring great restrictions and constraints to the project schedule. However, if the address setting information is sent from the bus, in the case where two or more devices have the same ...

Abstract

The invention provides a remote setting method, configuration device, working device and machine-readable storage medium of a device address in a local area network, and relates to the technical field of the Internet of Things. In this setting method, when there are at least two working devices in the local area network with the same current address, taking these working devices as target working devices, the configuration device sends an address setting command to the target working device, and then the target working device sets the command according to the address. Set its own current address as a new address with a specified probability, and perform address setting cyclically until all target working devices no longer have at least two working devices with the same current address. The solution of the invention solves the problem of address collision in the bus setting address, and can conveniently and efficiently perform the remote address setting of multiple working devices when the addresses conflict with multiple working devices.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a remote setting method of a device address in a local area network, a configuration device, a working device and a machine-readable storage medium. Background technique [0002] In the Internet of Things system, no matter wired bus network or wireless network, there is a common feature: after a message is sent, it will be received by multiple nodes. Therefore, each node requires address implementations to be distinct from each other. For example, for modbus rtu mode, the receiver processor first checks whether the address in the received information frame matches itself, and only the matching frame is valid. Conversely, as long as the addresses match, the frame is valid. This means that it is difficult to distinguish between devices with the same address. Therefore, in the prior art, the address of each device is generally set independently. [0003] There are...
