High formwork safety monitoring system and method

Abstract

This invention discloses a safety monitoring system and method for high-support formwork. It is an automated monitoring system and method for high-support formwork based on vibrating wire sensors (axial force gauges, displacement gauges, etc.), a data acquisition instrument, and a safety monitoring cloud platform. The vibrating wire sensors (axial force gauges, displacement gauges, etc.) are installed on the supporting force-bearing components of the high-support formwork and monitor their physical quantities such as force and displacement. The data acquisition instrument is wired to the vibrating wire sensors and converts the analog electrical signals transmitted from the sensors into digital signals, which are then transmitted to the remote safety monitoring cloud platform via a 4G network. The safety monitoring cloud platform calculates the corresponding physical quantities from the digital signals using formulas and issues an early warning alarm when the physical quantities exceed threshold values.

Description

Technical Field

[0001] This invention relates to the field of safety monitoring in building construction. More specifically, this invention relates to an automated monitoring system and method for high-formwork structures. Background Technology

[0002] High-formwork refers to formwork operations with a height of 8 meters or more, playing a crucial role in construction engineering. With the rapid development of my country's real estate construction industry, the application of high-formwork is becoming increasingly common. Correspondingly, the safety of high-formwork construction is receiving increasing attention. Due to the characteristics of high-formwork construction, and with the continuous increase in the scale and complexity of buildings, the safety management of high-formwork construction faces increasingly greater challenges. Construction accidents are frequent, often resulting in mass casualties. When the height of the formwork support reaches the high-formwork standard, the steel pipes of the support need to withstand enormous pressure. Once this pressure threshold is exceeded, the steel pipes or other supporting components may bend and deform, causing changes in the overall mechanical structure of the high-formwork, leading to partial collapse or overall overturning accidents, posing a serious threat to the lives and property of construction workers.

[0003] Traditional safety monitoring in high-formwork construction relies primarily on manual, periodic measurements using equipment such as total stations to detect deformation of the steel pipes. However, this method has significant drawbacks: First, there is an interval between adjacent measurements; if the deformation of the steel pipe occurs within this interval, accidents may occur due to delayed evacuation of personnel. Second, the internal components of high-formwork are densely packed, and manual observation can only capture deformation on the periphery of the formwork system, failing to obtain information on internal changes, resulting in poor monitoring effectiveness.

[0004] To ensure the safety of personnel and property in construction companies, a reliable automated safety monitoring system for high-formwork systems is essential. For example, by installing high-precision sensors and automatic digital data acquisition instruments, key parameters such as support deformation and upright axial force of the high-formwork support system can be monitored in real time. These systems can read the latest data and issue warning signals when monitored values ​​exceed physical thresholds, reminding construction personnel to evacuate in time. However, although these systems improve monitoring efficiency and accuracy to some extent, problems such as unstable data transmission and complex equipment installation still exist.

[0005] Therefore, this invention proposes a novel safety monitoring system for high-formwork structures. By integrating modules such as vibrating wire sensors, it aims to achieve real-time, continuous, and accurate monitoring of parameters such as stress, axial force, pressure, horizontal displacement, and vertical displacement of high-formwork structures. This system not only overcomes the shortcomings of traditional high-formwork safety monitoring methods but also enables real-time uploading of safety monitoring data to a safety monitoring cloud platform via wireless transmission modules (such as 4G communication modules). This achieves remote data transmission and analysis, further improving monitoring efficiency and accuracy. Summary of the Invention

[0006] The purpose of this invention is to provide a high-support formwork safety monitoring system and method based on a vibrating wire sensor, to solve the problems mentioned in the background art. The technical solution adopted by this invention is as follows:

[0007] This invention relates to software for a high-formwork safety monitoring system. The software aims to achieve comprehensive, real-time, and intelligent monitoring of the safety status of high-formwork structures by integrating multiple functional modules, thereby improving construction safety and efficiency.

[0008] Specifically, the software of the high formwork safety monitoring system of the present invention includes the following core modules:

[0009] Data Acquisition Module: This module is responsible for receiving real-time data from various vibrating wire sensors deployed on the high-formwork structure. These vibrating wire sensors can monitor key safety parameters of the high-formwork structure, such as stress, axial force, horizontal displacement, vertical displacement, and pressure. The data acquisition module ensures the real-time nature and accuracy of this data through an efficient data transmission protocol.

[0010] The data acquisition module can be connected to the vibrating wire sensor via a wired connection, convert the analog signal from the vibrating wire sensor into a digital signal, and remotely transmit it to the high formwork safety monitoring cloud platform via 4G through the built-in wireless communication module.

[0011] The high-support formwork safety monitoring cloud platform is a remote website used to process, judge, store, and manage the data transmitted from the data acquisition instrument.

[0012] Furthermore, the high-formwork safety monitoring cloud platform includes a data processing and analysis module: This module receives raw data from the data acquisition module and performs data preprocessing, including data verification and outlier removal, to ensure data accuracy and reliability. Subsequently, the module uses specific programs to conduct in-depth analysis of the processed data, determining whether there are any safety hazards or anomalies in the high-formwork structure. This step is crucial for the timely detection and resolution of potential problems.

[0013] Alarm and Notification Module: When the data processing and analysis module detects security risks or anomalies, this module will automatically trigger an alarm and send alarm information to relevant personnel via preset communication methods (such as DingTalk, WeChat Work, mobile app push notifications, etc.). The alarm information includes detailed information such as the alarm type, time of occurrence, and specific measurement point location, enabling relevant personnel to respond quickly and take necessary measures.

[0014] User Interface Module: This module provides an intuitive and clear user interface, allowing users to remotely access and monitor the status of the high-support formwork system. Users can view real-time monitoring data, historical data, alarm information, and security system configurations through this interface. Furthermore, users can perform necessary operations on the system, such as setting measurement point names, units of measurement physical quantities, alarm thresholds for measurement physical quantities, adjusting monitoring parameters, and managing DingTalk or WeChat Work API interface keys. This module is designed to improve user convenience and system flexibility.

[0015] Furthermore, the software of the high formwork safety monitoring system of the present invention also includes the following additional functional modules:

Through intuitive graphical displays, users can gain a clearer understanding of the safety status of the high-support formwork structure, thereby enabling them to make better decisions.

[0017] Furthermore, it also includes data export and report generation functions: This module allows users to export monitoring data and analysis results to common file formats (such as Excel, PDF, etc.) and automatically generate monitoring reports. This function provides users with a convenient data management and report generation tool, which helps users to conduct subsequent data analysis and processing.

[0018] Furthermore, it also includes: multi-user access control functionality: as a further extension of the user interface module, this function allows system administrators to assign different access and operation permissions to different users. Through granular access control, system security and data confidentiality can be ensured, preventing unauthorized user access or disruption of the operating system.

[0019] In summary, the software of the high-formwork safety monitoring system of the present invention integrates multiple functional modules to achieve comprehensive, real-time, and intelligent monitoring of the safety status of high-formwork structures. This software not only improves construction safety and efficiency but also provides users with convenient data management and report generation tools.

Unlike existing technologies, when the backend safety monitoring cloud platform determines that an alarm is to be issued, this invention will simultaneously call real-time communication tools such as DingTalk and WeChat Work to issue an alarm, which can more quickly remind users to take measures.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0028] It should be understood that terms such as “having” and “including” used herein do not exclude the presence or addition of one or more other elements or combinations.

[0029] An automated safety monitoring system for high-support formwork includes three main modules: vibrating wire sensors (axial force gauges, anchor cable gauges, earth pressure cells, displacement gauges, etc.), data acquisition instruments, and a safety monitoring cloud platform.

[0030] Vibrating wire sensors (axial force gauges, anchor cable gauges, earth pressure cells, displacement gauges, etc.) are connected to the data acquisition unit via wired connection. The data acquisition unit has a vibrating wire reading module that converts the analog electronic signals sent from the vibrating wire sensors (axial force gauges, anchor cable gauges, earth pressure cells, displacement gauges, etc.) into digital signals. The communication module then remotely transmits the digital signals to the high-support formwork safety monitoring cloud platform via a 4G network.

[0031] The high-support formwork safety monitoring cloud platform is deployed on a remote cloud platform, and users can access it through a browser.

[0032] The data acquisition device is deployed at the construction site and is enclosed in an anti-electromagnetic metal enclosure.

[0033] First, install vibrating wire sensors (axial force gauges, anchor cable gauges, earth pressure cells, displacement gauges, etc.). Installation requires approval from professional safety supervisors or monitoring personnel and must be installed at their designated measuring points. These personnel must also determine the physical quantity thresholds for each measuring point based on the project's construction conditions. Finally, they must input these threshold values ​​into the user interface module of the high-formwork safety monitoring cloud platform. These threshold values ​​become the alarm thresholds for the platform.

[0034] Solar photovoltaic panels or lithium batteries are connected to the data acquisition unit. The data acquisition unit automatically sends an excitation current to the connected vibrating wire sensor. Upon receiving the current, the vibrating wire sensor sends a corresponding analog electrical signal to the data acquisition unit. This analog electrical signal is generated by the built-in vibrating wire coil of the vibrating wire sensor and contains monitoring information such as force and displacement. The digital acquisition unit begins to read the vibrating wire analog electrical signals transmitted from each connected vibrating wire sensor and converts them into digital signals. The data acquisition unit then sends the digital signals via a 4G network to a specific URL on the designated high-support formwork safety monitoring cloud platform. The data processing and analysis module of the high-support formwork safety monitoring cloud platform automatically receives, processes, judges, stores, and manages the digital signals sent to the specific URL.

[0035] The user interface module of the high-support formwork safety monitoring cloud platform allows users to set the name, unit, and physical quantity threshold of each measuring point. When the data processing and analysis module of the platform detects that the physical quantity of the digital signal transmitted from a measuring point exceeds the physical quantity threshold set in the user interface module, it automatically invokes the platform's alarm and notification module to issue an alarm via real-time communication tools such as DingTalk and WeChat Work. The user interface module can also display real-time and historical monitoring data to users in the form of charts, line graphs, or bar graphs, and provides file download services.
