The application of information systems has gradually become popular in construction sites of buildings, bridges, tunnels, and infrastructure industries.

Most of the existing information management systems focus on video surveillance, environmental monitoring, and equipment monitoring. The core issue that smart construction sites need to address is still personnel safety, to avoid the occurrence of personnel safety accidents, and secondly, to improve production efficiency and reduce production costs. With the deepening development of IoT technology, the maturity of sensing technology, and transmission technology,The rapid development of 5G has provided a foundation for the development of higher intelligence IoT technology.

To achieve system functionality, this solution optimizes various technical solutions through several steps:

2.3.1 Implementing Cross System Fusion Network Applications Based on Unified IoT Network

The front-end of this plan is based onUWB (Ultra Wideband Positioning Technology) and Bluetooth are used to build a wireless IoT network for smart construction sites, and combined with a local area network or a fast access wide area network to form a complete IoT network architecture. talisman《Outline for the Development of Informationization in the Construction Industry from 2016 to 2020The requirements in.

2.3.2 Selection of IoT transmission technology

Wide Area Internet of Things Network:

Mainly relying on the operator's network, with stable and reliable performance, China's leading IoT networkNB-IOTNarrowband Internet of Things,CAT1The medium speed network,4GHigh speed network, and5G backbone network

Local Internet of Things Network:

Mainly self built by users, common examples includeLORAThe internet,RFIDNetwork, Bluetooth network,UWB networks, etc. Each network has its own characteristics that are suitable for different scenarios.

LORA network: suitable for areas where telecommunications networks cannot cover, with low deployment costs and wide single station coverage, but without positioning function, low tag capacity, suitable for low-frequency and low-speed data transmission, and widely used in the agricultural field.

RFIDnetworkSuitable for logistics and related industries, with extremely low tag costs and certain positioning functions, but data transmission is limited to identity IDs and the transmission volume is limited.

Bluetooth network: suitable for a wide range, low tag cost, supports uplink and downlink, has a large bandwidth, supports fuzzy positioning and small areasAOA precise positioning, with a small coverage area for a single station.

UWB network: suitable for a wide range, low tag power consumption, high cost, large tag capacity, large bandwidth, high positioning accuracy, overall high cost.

Our solution combines the wide area Internet of Things and local area Internet of Things, Integrating Bluetooth andThe advantages of UWB and other networks, combined with wearable devices as fusion tags, have been utilized to construct a multi-mode collaborative and efficient IoT network.

2.3.3 Selection of positioning technology

Outdoor positioning network:

mainlyGNSSPositioning technology, such as BeidouGPS， Ordinary positioning can achieve lane level positioning;

based onRTKPositioning technology, through ground basedCOSR base station differential enables outdoor sub meter or centimeter level positioning, but relies on wide area networks or private networks to establish communication and achieve location management

Indoor positioning network:

The commonly used positioning technologies can be roughly divided into two categories:

One type is to implement continuous coordinate measurement and positioning technology, such as:RSSI (measuring target coordinates based on signal strength), AOA (measuring target coordinates based on signal arrival angle), TDOA (measuring target coordinates based on signal arrival time difference);

The second type is area perception and positioning technology, such as ultrasonic area perception and positioning technology, low-frequency signal excitation area perception and positioning technology.

Continuous coordinate measurement and positioning technology is based on obtaining real-time position coordinates of personnel, so it can not only identify personnel's cross regional activities but also identify their specific location within a certain area.

The advantage of region aware positioning technology is that it can accurately distinguish the cross regional activities of personnel, but the disadvantage is that it cannot perceive the specific location of personnel after entering a certain area.

Based on the advantages and disadvantages of the two types of positioning technologies mentioned above, this system will integrate multiple positioning technologies and use different positioning technologies according to different functions and regions.

1. Infrared Bluetooth anchor point positioning, mainly used for indoor positioning in narrow spaces, effectively reducing base station deployment data and lowering costs

2. Bluetooth AOA is mainly suitable for spaces below 30 square meters that require precise positioning, with low overall cost

3. UWB one-dimensional, suitable for narrow space positioning, cost saving, and obvious advantages
