Description

Technical Field

[0001] This invention belongs to the field of wireless communication technology, and more specifically, relates to a multi-mode heterogeneous networking data distribution device and method for complex construction environments. Background Technology

[0002] Construction site environments are complex and varied, presenting challenges such as signal obstruction from tall buildings and limitations in basements and core tunnels. Traditional mobile networks often fail to guarantee reliable communication coverage, preventing data from some intelligent construction equipment from being uploaded to the public mobile network. Therefore, researching a data distribution device for intelligent construction equipment in complex construction environments is of great significance.

[0003] Existing data distribution methods in construction environments often rely on wireless ad hoc network (WAN) technology. WAN technology enables intelligent construction equipment to automatically form a network even without fixed infrastructure, flexibly responding to rapid changes on the construction site. With the assistance of WAN, intelligent construction equipment in areas with low mobile network coverage can distribute data along the WAN to other intelligent construction equipment in areas with high mobile network coverage, thereby addressing their need for high-quality mobile network access. However, due to the extremely uneven distribution of intelligent construction equipment on the construction site, it is difficult for construction equipment alone to form an interconnected WAN, resulting in poor communication quality.

Attached Figure Description

[0034] Figure 1 This is a diagram of a three-layer heterogeneous multimode network architecture provided in an embodiment of the present invention, which includes multimode access, gateway self-organizing network, and multi-point outgoing. Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0036] This invention takes into account the needs of multiple devices accessing the site and the need for low-latency communication. The design of an efficient multi-mode heterogeneous networking data distribution device for complex construction environments involves two aspects: first, it meets the access requirements of multiple devices and can transmit data to the mobile public network through the backbone network layer; second, it meets the low-latency requirements of data transmission and can upload and process data in a timely manner.

[0037] To achieve the above objectives, in a first aspect, the present invention provides a multi-mode heterogeneous networking data distribution device for complex construction environments, comprising: a distribution control module and a backbone network layer;

[0038] The backbone network layer includes: multiple multimode gateway devices; each multimode gateway device includes: a first communication module and a second communication module; the first communication module is used to receive the data to be uploaded from the construction equipment and to communicate with the first communication modules of other multimode gateway devices; the second communication module is used to receive the data to be uploaded from the first communication module and upload it to the mobile public network under the control of the distribution control module.

[0039] The distribution control module controls whether the second communication module of each multimode gateway device uploads data to the mobile public network, so that the backbone network layer can upload the total data of all construction equipment connected to the backbone network layer to the public network with the minimum upload time.

[0040] This invention adopts a three-layer heterogeneous multimode network design with multimode access + gateway self-organizing network (i.e., backbone network layer) + multi-point outgoing method, which enables multiple devices to transmit data to the mobile public network. In this process, the upload link and distribution link size characteristics of different multimode gateway devices are fully considered, so that data can be distributed, uploaded and processed in a timely manner.

[0041] Specifically, such as Figure 1 The diagram illustrates a three-layer heterogeneous multimode network architecture: multimode access, gateway self-organizing network, and multi-point outgoing. Local access corresponds to the multimode access function, indicating that multiple different construction equipment can connect to the wireless backbone network formed by the multimode gateway devices, and the data is uniformly transmitted to the mobile public network by this backbone network layer. The self-organizing network gateway corresponds to the backbone network layer. In the gateway self-organizing network, each multimode gateway device includes a first communication module and a second communication module. The first communication module is responsible for receiving data from multiple construction equipment accesses and for networking among multiple multimode gateway devices; the second communication module is responsible for outgoing data to the mobile public network. This gateway self-organizing network is the backbone network in the entire framework. 5G outgoing corresponds to multi-point outgoing, indicating that the second communication module of the multimode gateway device is used to outgoing the accessed data to the mobile public network. This design enables data from multiple construction equipment to be transmitted to the mobile public network with low latency.

Finally, the total data size to be uploaded by the gateway to the mobile public network is denoted as Q.
