It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0025] like Figure 1 As shown, a smart construction site management system includes: a server 1, an Internet of Things gateway 2, a sensor data acquisition terminal 3, a data acquisition module, a smart safety helmet 5, and a PC monitoring terminal 6; the smart safety helmet 5 is connected to the sensor data acquisition terminal 3 via a wireless network.

[0026] The sensor data acquisition terminal 3 is connected to the server 1 through the Internet of Things gateway 2, summarizes the data collected by the smart safety helmet 5 and the data acquisition module, and transmits it to the server 1 through the Internet of Things gateway 2, so as to realize real-time monitoring of various parts of the construction site.

[0027] The mobile terminal 7 is connected to the server 1 via a wireless network. The IoT gateway 2 is connected to the server 1 via a wired or wireless network.

[0028] The server 1 is connected to the PC monitoring terminal 6 through the network; the server 1 plays a core role in data processing and network information transmission in the system. After receiving the data transmitted by the IoT gateway 2, it is sorted, analyzed and stored, and sent to the PC monitoring terminal 6 and the mobile terminal 7 through the network for real-time status inspection and long-term data analysis. The PC monitoring terminal 6 receives the monitoring data sent by the server 1 and displays the real-time status of the entire construction site through a graphical interface, which is convenient for managers to conduct remote monitoring and management.

[0029] The IoT gateway 2 provides a network interface with the server 1 for the sensor data collection terminal, realizes data transmission through a wired or wireless network, and realizes the cloudification of local data. The physical gateway adopts a Zigbee gateway.

[0030] The sensor data acquisition terminal 3 uses ZigBee self-organizing network to form a network node, which completes information collection, network access, data transmission, edge computing, data storage and other functions in a decentralized manner. The ZigBee terminal node is implemented based on TI's CC2530 chip. The chip has a built-in enhanced 8051CPU core, is equipped with sufficient ROM and RAM, and has 5 operating modes: active, idle, PM1, PM2, and PM3. It also supports shutting down unnecessary functional parts to achieve energy saving. The short transition time between operating modes further ensures low energy consumption. These features make it particularly suitable for systems with ultra-low power requirements. The development of CC2530 can be based on the industry-leading ZigBee protocol stack provided by TI. The protocol stack provides a powerful and complete ZigBee solution, providing all resources in the physical layer and media access control layer, which can be used directly by developers, thereby accelerating the application development process. CC2530 is used as the terminal node, and its typical structure is as follows Figure 5 shown.

[0031] like Figure 3 As shown, the data acquisition module includes: an access control card reader 41, a construction site perimeter camera 42, an operation monitoring camera 43, and an environmental monitoring module 44. The data acquisition module is used to collect various types of data on the construction site and is electrically connected to the sensor data acquisition terminal 3. The access control card reader 41, the construction site perimeter camera 42, the operation monitoring camera 43, and the environmental monitoring module 44 are electrically connected to the sensor data acquisition terminal 3 through a network. The data acquisition module includes sensors and camera systems, which can collect information on the construction site environment, the working status of the equipment, and the actions of the workers, so as to monitor the overall situation in combination with the smart safety helmet 5.

[0032] The environmental monitoring module 44 includes an air temperature and humidity sensor 441, a sewage water quality monitor 442, and a dust and noise detector 443. This module provides real-time and accurate environmental data for construction site managers, helping them understand the real-time environmental conditions of the construction site, such as temperature, humidity, noise, and air quality.

[0033] Air temperature and humidity sensor 441: used to monitor the ambient temperature and humidity of the construction site in real time. Based on this data, managers can provide workers with a more comfortable working environment and prevent safety accidents caused by excessive temperature or humidity.

[0034] Sewage water quality monitor 442: used to detect the sewage discharge situation at the construction site in real time to prevent improper sewage treatment from polluting the environment.

[0035] Dust and noise detector 443: Dust and noise are two major sources of pollution at construction sites. This instrument can monitor the dust and noise conditions at the construction site in real time. Once the standards are exceeded, the system will automatically issue an alarm so that timely measures can be taken to improve the situation. The instrument uses sewage water quality detectors from Hach of the United States and dust and noise detector 443 from Svantek of Germany.

[0036] like Figure 2 As shown, the smart safety helmet 5 includes a safety helmet body 51, an infrared sensor 52, a three-dimensional acceleration sensor 53, a GPS positioning chip 54, a ZigBee communication chip 55, and a rechargeable lithium battery 56; the safety helmet body 51 is designed with a raised circuit board installation position on the forehead part of the original safety helmet, and the circuit board is placed inside; the wearer's position, action status and whether the safety helmet is worn normally can be detected in real time, and transmitted to the sensor data acquisition terminal 3 through the wireless network, so as to realize real-time monitoring of the workers.

[0037] like Figure 4 As shown, the circuit board is integrated with an infrared sensor 52, a three-dimensional acceleration sensor 53, a GPS positioning chip 54, a ZigBee communication chip 55, and a rechargeable lithium battery 56; the infrared sensor 52, the three-dimensional acceleration sensor 53, and the GPS positioning chip 54 are all electrically connected to the ZigBee communication chip 55, and the rechargeable lithium battery 56 provides working voltage for the sensor and the chip. The smart helmet 5 also includes a charging interface, which is connected to the rechargeable lithium battery 56.

[0038] The infrared sensor 52 is mainly responsible for identifying the biological characteristics of the user. It does not directly contact the object being measured during measurement, so there is no friction, and it has the advantages of high sensitivity and fast response. The perception and recognition of the human body by the smart helmet 5 can be used as basic data to determine whether the on-site personnel are effectively wearing the helmet, assist in realizing the statistics of the number of people on the scene, and ensure the safety of users.

[0039] The three-dimensional acceleration sensor 53 is mainly used to monitor the user's motion state in three-dimensional space. By extracting the characteristics of daily motion behavior, the sensor can identify the user's five actions such as standing, walking, running, and going up and down stairs. Its use can realize the perception of the safety status of the person wearing the helmet.

[0040] The Global Navigation Satellite System (GNSS) is a wireless base station navigation and positioning system that can provide users with all-weather three-dimensional coordinates, speed and time information at any location on the surface of the earth or near the ground. The system consists of a group of satellites, ground control stations and user equipment. At present, the Global Positioning System (GPS) is one of the most well-known and widely used GNSS systems. As the most widely used and most compatible model of GNSS, the addition of the GPS (Global Positioning System) global positioning system can realize the real-time positioning function of the wearer of the smart helmet 5, so as to track the corresponding personnel in an emergency, provide effective data for construction safety and efficiency, and also buy time for emergency rescue when an accident occurs.

[0041] Working principle of the utility model: First, the data collection module including the access control card reader 41, the perimeter camera 42 of the construction site, the operation monitoring camera 43, the environment monitoring module 44, etc., starts to collect data on the construction site. At the same time, the smart safety helmet 5 also starts to collect data such as the worker's action status and work area through the internal infrared sensor 52, the three-dimensional acceleration sensor 53, the GPS positioning chip 54, the ZigBee communication chip 55, etc. Then, all these data are transmitted to the sensor data collection terminal 3 through the wireless network, and then transmitted to the core server 1 through the Internet of Things gateway 2.

[0042] Next, after receiving the data, the server 1 processes and analyzes it, and determines whether there are any environmental or worker safety issues based on the set threshold. If there are any problems, a warning message will be sent to the PC monitoring terminal 6 and the mobile terminal 7 through the network. Finally, the construction site manager receives this information through the PC monitoring terminal 6 or the mobile terminal 7, and can process and make decisions based on the actual situation.

[0043] The entire process achieves comprehensive monitoring of the status of each system and personnel on the construction site, improves the management efficiency of the construction site, and effectively ensures the safety of workers.
