Description

Technical Field

[0001] The invention relates to a construction safety system, in particular to a construction electronic fence system. Background Art

[0002] In modern construction management, real-time monitoring and management of construction site personnel and vehicles is the key to ensuring construction safety and improving work efficiency. Traditional construction site management methods, such as manual patrol and monitoring, have disadvantages such as high labor costs, limited monitoring range, and slow response speed, and cannot meet the high standards of modern construction management.

[0003] Existing construction management systems on the market often have problems such as single functionality, poor flexibility, and imperfect early warning mechanisms when integrating Beidou positioning technology. For example, although some systems can set up electronic fences, they lack effective matching and early warning mechanisms and are unable to respond to abnormal situations in a timely manner. Summary of the invention

[0004] In view of the above situation, it is necessary to provide a construction electronic fence system that solves at least one of the above problems, including:

[0005] An electronic fence construction module is used to measure and determine the positions of multiple stake points through a Beidou positioning terminal, and to plot these stake points on a map to connect them to form a closed-loop polygonal electronic fence, and to create an information table containing the number and name of the electronic fence and the longitude and latitude coordinate information of each stake point, and to generate first data;

[0006] A positioning information acquisition module, used to equip construction personnel or vehicles with the Beidou positioning terminal, the Beidou positioning terminal records the location information of the construction personnel or vehicles in real time, the location information includes the terminal number, longitude and latitude, and timestamp, and generates second data;

[0007] An electronic fence matching module receives and matches the first data and the second data, determines the electronic fence to which they belong, determines in real time whether the location of the construction personnel or vehicle is within the electronic fence to which they belong, and generates third data;

[0008] The early warning module is used to receive the third data. The early warning module is provided with a threshold. When one or more data of the third data exceeds the set threshold, the early warning module activates the early warning mechanism.

[0009] Preferably, the electronic fence construction module includes a map update module, which automatically detects whether the current map version is consistent with the preset latest version at 0:00 am every day. If it is inconsistent and the time since the last update is more than 30 days, the map data update process is started to download and immediately apply the latest map data from the designated server, and record the update log at the same time.

[0010] Preferably, the electronic fence construction module includes an accuracy detection unit, which performs 10 positioning accuracy tests continuously. If more than 5 test results show that the measurement accuracy of the Beidou positioning terminal is lower than the preset 3-meter accuracy threshold, the accuracy alarm mechanism is triggered and an accuracy test report is generated.

[0011] Preferably, after receiving the location information sent by the Beidou positioning terminal, the positioning information acquisition module verifies whether the terminal number in the location information exists in the terminal list registered by the system, and checks whether the longitude and latitude and timestamp meet the preset format requirements. If all conditions are met, the second data is generated and sent to the electronic fence matching module for processing.

[0012] Preferably, after receiving the first data and the second data, the electronic fence matching module will perform terminal number matching and position judgment. If the terminal number is consistent with the number in the information table, the third data will be generated; if the location exceeds the electronic fence boundary, the crossing time and location will be recorded, and the third data containing the crossing information will be generated.

[0013] Preferably, the early warning module will continue to judge the third data, and if the third data containing out-of-bounds information is detected and the out-of-bounds time exceeds a preset threshold of 10 minutes, the early warning mechanism will be activated.

[0020] In the description of this utility, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility can be understood by specific circumstances.

[0021] See also Figure 1 The construction electronic fence system of the embodiment of the present invention includes an electronic fence construction module, which is used to measure and determine the positions of multiple stakes through a Beidou positioning terminal, and mark these stakes on a map to connect and form a closed-loop polygonal electronic fence, and at the same time create an information table, the information table contains the number, name and longitude and latitude coordinate information of each stake of the electronic fence, and generates first data; a positioning information acquisition module, which is used to equip construction personnel or vehicles with the Beidou positioning terminal, the Beidou positioning terminal records the position information of the construction personnel or vehicles in real time, the position information includes the terminal number, longitude and latitude and timestamp, and generates second data; an electronic fence matching module, which receives and matches the first data and the second data, determines the electronic fence to which it belongs, judges in real time whether the position of the construction personnel or vehicle is located in the electronic fence to which it belongs, and generates third data; an early warning module, which is used to receive the third data, the early warning module is provided with a threshold, and when one or more of the third data exceeds the set threshold, the early warning module starts the early warning mechanism.

[0022] In the above embodiment, the construction electronic fence system is a comprehensive system that integrates Beidou positioning technology, geographic information system (GIS) and intelligent data analysis functions, and aims to achieve real-time monitoring and early warning of construction site personnel and vehicles. The working principle of the system can be described coherently as follows: the Beidou positioning terminal is used to accurately locate and measure multiple stakes at the construction site, and the longitude and latitude coordinate information of each stake is obtained. This information is then used to plot the boundaries of the electronic fence on the map to form a closed-loop polygonal electronic fence. During the mapping process, the system will simultaneously create an information table to record in detail the number, name and longitude and latitude coordinate information of each stake of the electronic fence, which will serve as the basic data for subsequent modules to match and judge. Immediately afterwards, the positioning information acquisition module begins to play its role. This module is responsible for equipping the construction personnel or vehicles at the construction site with Beidou positioning terminals and receiving the location information sent by these terminals in real time. These location information contains key data such as terminal number, longitude and latitude, and timestamp, ensuring that the system can accurately track the specific location of each construction personnel or vehicle. Once these information are received, the positioning information acquisition module will immediately verify them to ensure that the terminal number exists in the terminal list registered by the system, and the longitude and latitude and timestamp meet the preset format requirements. Only the verified qualified location information will be generated as the second data and transmitted to the electronic fence matching module. The electronic fence matching module is the core part of the system. It is responsible for receiving the first data and the second data, and performing efficient matching and judgment. After receiving the data, the module first finds the corresponding electronic fence number in the information table according to the terminal number in the second data. According to the longitude and latitude coordinate information in the second data, it is judged whether the location is located in the corresponding electronic fence. If the location is within the electronic fence, the third data is generated normally; if the location exceeds the boundary of the electronic fence, the module will immediately record the time and location of the crossing, and generate the third data containing the crossing information. Finally, the early warning module is responsible for receiving the third data and making early warning judgments according to the preset threshold. It will analyze the crossing information and other related indicators (such as crossing time, speed, etc.) in the third data in detail and compare them with the preset threshold. Once it is found that any one or more indicators exceed the set threshold, the early warning module will immediately start the early warning mechanism. There are many forms of early warning, such as sending early warning text messages, email notifications, system message prompts, etc., which are aimed at promptly notifying managers to pay attention to abnormal situations so that they can quickly take appropriate measures. Throughout the entire work process, the various modules of the construction electronic fence system maintain close contact and efficient collaboration. Through data exchange and synergy, they jointly complete the real-time monitoring and early warning tasks of personnel and vehicles on the construction site. This integrated workflow not only improves the operating efficiency of the system, but also ensures the accuracy and real-time nature of the data, providing a strong guarantee for the safety management and decision-making support of the construction site.

[0023] Please refer to Figure 1 In another embodiment, the electronic fence construction module includes a map update module, which automatically detects whether the current map version is consistent with the preset latest version at 0:00 a.m. every day. If it is inconsistent and the time since the last update is more than 30 days, the map data update process is started to download and immediately apply the latest map data from the designated server, and record the update log at the same time.

[0024] In the above embodiment, in order to ensure the accuracy of map data, the map update module plays a key role. The module adopts an automated update mechanism to automatically detect whether the currently used map version is consistent with the preset latest version at 0:00 am every day. This detection process is based on the comparison of version numbers and is simple and efficient. If the detection result shows that the current version is inconsistent with the latest version and it has been more than 30 days since the last update, the map update module will start the map data update process. In the update process, the map update module will first download the latest map data from the designated server. This server is usually maintained by the map data provider and updates are released regularly. The download process is usually carried out through a secure network connection to ensure the integrity and security of the data. Once the download is completed, the map update module will immediately apply the new map data to the system and replace the original old data. While the map data is updated, the map update module will also record the update log. These logs record in detail the update time, version number, data source and any possible problems or exceptions. These log information is of great significance for subsequent system maintenance and troubleshooting. By combining the map update module with the electronic fence construction module, the construction electronic fence system can realize automatic update and maintenance of map data. This mechanism ensures that the system always uses the latest map data, thereby improving the accuracy of the electronic fence and the accuracy of positioning matching. At the same time, the automated update mechanism also greatly reduces the need for manual intervention and improves the operating efficiency and stability of the system. In addition, the setting of the map update module also takes into account the frequency and timing of data updates. Automatically checking whether the version is consistent at 0:00 am every day can ensure that the system uses the latest map data at the beginning of each day. The setting of updating only when the last update time is more than 30 days away avoids the impact of too frequent updates on system performance, and also ensures that the data can be updated in time when there are major changes. In summary, the map update module in the electronic fence construction module of the construction electronic fence system ensures that the system always uses the latest map data through an automated version detection and update mechanism. This mechanism not only improves the accuracy of the electronic fence and the accuracy of positioning matching, but also improves the operating efficiency and stability of the system. At the same time, by recording update logs and setting reasonable update frequency, the maintainability and troubleshooting capabilities of the system are further enhanced.

[0025] Please refer to Figure 1 In another embodiment, the electronic fence construction module includes an accuracy detection unit, which performs 10 positioning accuracy tests continuously. If more than 5 test results show that the measurement accuracy of the Beidou positioning terminal is lower than the preset 3-meter accuracy threshold, the accuracy alarm mechanism is triggered and an accuracy test report is generated.

[0026] In the above embodiment, this test is to ensure that the measurement accuracy of the positioning terminal can meet the accuracy requirements preset by the system, thereby ensuring the accuracy and effectiveness of the electronic fence. The workflow of the accuracy detection unit starts with 10 consecutive positioning accuracy tests. Each test is a performance evaluation of the Beidou positioning terminal, and its measurement accuracy is evaluated by comparing the difference between the actual position and the position measured by the positioning terminal. This test method can comprehensively and objectively reflect the performance status of the positioning terminal. During the test, the accuracy detection unit records the results of each test, including the actual position, the measured position, and the difference between them. Then, it will judge whether the measurement accuracy of the positioning terminal meets the preset accuracy threshold based on these results. In this case, the preset accuracy threshold is 3 meters, which is a reasonable value set based on system requirements and actual application scenarios.

[0027] If more than 5 of the 10 consecutive tests show that the measurement accuracy of the Beidou positioning terminal is lower than the 3-meter accuracy threshold, the accuracy detection unit will trigger the accuracy alarm mechanism. The function of this mechanism is to send an alarm to the system administrator, reminding them that the positioning terminal may have performance problems and needs to be inspected and repaired. At the same time as the alarm is triggered, the accuracy detection unit will also generate an accuracy test report. This report records the results, data analysis and conclusions of each test in detail, providing the system administrator with comprehensive information about the performance status of the positioning terminal. Through this report, the system administrator can clearly understand the performance status of the positioning terminal and make corresponding processing decisions. Combining the accuracy detection unit with the electronic fence construction module can achieve accurate construction and effective management of the electronic fence. When building the electronic fence, the accuracy detection unit evaluates and verifies the performance of the positioning terminal to ensure the accuracy and reliability of the electronic fence. At the same time, during the operation of the electronic fence, the accuracy detection unit can also monitor and detect the positioning terminal in real time, timely discover and solve potential performance problems, and ensure the stable operation of the electronic fence. In addition, the setting of the accuracy detection unit also reflects the rationality and scientificity of the system design. By setting a reasonable number of tests and accuracy thresholds, the false alarm rate can be reduced while ensuring the detection effect. At the same time, by generating an accuracy test report, comprehensive and detailed information support can be provided to system administrators to help them better understand the system performance and operating status. In summary, the accuracy detection unit in the electronic fence construction module in the construction electronic fence system verifies the performance of the Beidou positioning terminal through continuous positioning accuracy tests to ensure the accuracy and reliability of the electronic fence. This mechanism not only improves the performance and stability of the system, but also provides strong technical support and information guarantee for system administrators.

[0028] Please refer to Figure 1 In another embodiment, after receiving the location information sent by the Beidou positioning terminal, the positioning information acquisition module verifies whether the terminal number in the location information exists in the terminal list registered by the system, and checks whether the longitude and latitude and timestamp meet the preset format requirements. If all conditions are met, the second data is generated and sent to the electronic fence matching module for processing.

[0029] In the above embodiment, the positioning information acquisition module will continuously monitor and receive the location information sent from each Beidou positioning terminal at the construction site. This information usually contains key data such as terminal number, longitude and latitude coordinates, and timestamp, which is an important basis for the system to locate and track personnel and vehicles. Once the location information is received, the positioning information acquisition module will immediately start the verification process. The first step of the verification is to check whether the terminal number in the location information exists in the terminal list registered by the system. This step is crucial because it can ensure that only legally registered devices can access the system and prevent illegal or unauthorized devices from interfering with the normal operation of the system. When verifying the validity of the terminal number, the system usually compares the received terminal number with the registered terminal list pre-stored in the database. If the terminal number cannot be found in the list, it means that the device has not been registered, and the system will refuse to process the location information sent by the device, and record the corresponding log for subsequent review. Next, the positioning information acquisition module will further verify whether the longitude and latitude and timestamp in the location information meet the preset format requirements. Longitude and latitude and timestamp are the core data in the location information, and their accuracy and standardization directly affect the accuracy of the system positioning. Therefore, the system will perform strict format verification on these data. For longitude and latitude data, the system will check whether it conforms to the standard longitude and latitude format (such as degrees, minutes, seconds or decimal format), and check whether it is within a reasonable range (such as the longitude and latitude range on the earth). If the longitude and latitude data do not meet the requirements, the system will consider the location information invalid and refuse to process further. For timestamp data, the system will check whether it conforms to the standard date and time format and verify whether it is the most recent timestamp (avoid using outdated location information). If the timestamp data does not meet the requirements or is outdated, the system will also refuse to process the location information. Only when the terminal number exists in the terminal list registered by the system and the longitude and latitude and timestamp meet the preset format requirements, the positioning information acquisition module will consider the location information valid and generate it as the second data. These second data will contain information such as the verified terminal number, longitude and latitude coordinates and timestamp, and will be sent to the electronic fence matching module for further processing and analysis. Before sending the second data, the positioning information acquisition module may also perform some additional processing on the location information, such as removing duplicate data, encrypting data, etc., to ensure the integrity and security of the data.

[0030] Please refer to Figure 1 In another embodiment, after receiving the first data and the second data, the electronic fence matching module will perform terminal number matching and position judgment. If the terminal number is consistent with the number in the information table, the third data is generated; if the location exceeds the electronic fence boundary, the crossing time and location are recorded, and the third data containing the crossing information is generated.

[0031] In the above embodiment, the electronic fence matching module will receive two main data inputs at the same time: the first data, i.e., the boundary information of the electronic fence, which is usually a set of multiple stake point coordinates, used to define a closed area on the map; the second data, i.e., the real-time location information from the Beidou positioning terminal, including the terminal number, longitude and latitude coordinates, and timestamp. After receiving these data, the electronic fence matching module will first match the terminal number. This step is to ensure that the system only processes the location information related to the registered device, thereby avoiding the interference of irrelevant data. The module will compare the terminal number in the second data with the device information table pre-stored in the system. The information table records the numbers of all registered devices and the corresponding electronic fence numbers. If the terminal number in the second data can find a matching item in the information table, the module will continue to perform subsequent location judgment; otherwise, the module will ignore the data and do not perform any processing. Next, the electronic fence matching module will perform location judgment. This step is the key to determining whether a person or vehicle has crossed the boundary. The module will use a spatial algorithm to determine whether the location is located in the corresponding electronic fence area based on the longitude and latitude coordinates in the second data. This usually involves geometric operations on coordinate points and judgment of intersections with the boundaries of the electronic fence. If the location is within the electronic fence area, the module will consider the location to be legal and continue to generate third data, which will contain terminal number, location information, and timestamp, etc., for subsequent log records or data analysis. However, if the location exceeds the boundary of the electronic fence, that is, an out-of-bounds event occurs, the electronic fence matching module will immediately start the out-of-bounds processing process. First, the module will record the time and specific location of the out-of-bounds event, which is crucial for subsequent early warning and emergency response. Then, the module will generate third data containing out-of-bounds information. These data not only contain basic information such as terminal number, out-of-bounds time and location, but may also contain some additional identification or flag bits for quickly identifying the type and severity of the out-of-bounds event. The generated third data will be sent to the subsequent early warning module for processing. The early warning module will trigger the corresponding early warning mechanism based on the out-of-bounds information in the third data, such as sending early warning text messages, email notifications or system messages, so that management personnel can promptly discover and handle out-of-bounds events.

[0032] Please refer to Figure 1 In another embodiment, the warning module will continue to judge the third data, and if the third data containing out-of-bounds information is detected and the out-of-bounds time exceeds the preset 10-minute threshold, the warning mechanism will be activated.

[0033] In the above embodiment, the early warning module continuously receives the third data from the electronic fence matching module. These data reflect the status of each positioning terminal at the construction site in real time, including key information such as whether it is in the electronic fence area, terminal number, longitude and latitude coordinates, and timestamp. After receiving these data, the early warning module will immediately parse and process them. During the data processing process, the early warning module will focus on the third data containing cross-border information. These data indicate that a certain positioning terminal has exceeded the predetermined electronic fence boundary, and there may be safety hazards or violations. In order to accurately determine the severity of the cross-border event, the early warning module will further analyze the key indicator of the cross-border time. Specifically, the early warning module will check the cross-border time recorded in each third data containing cross-border information. This timestamp records the specific moment when the positioning terminal first crosses the border. Then, the early warning module will compare the current time with the cross-border timestamp and calculate the cross-border duration. This duration is crucial for evaluating the urgency and severity of the cross-border event. In order to reasonably set the early warning threshold, the early warning module will preset a cross-border time threshold based on the actual situation and safety management requirements of the construction site. In this case, the threshold is set to 10 minutes. This means that if a positioning terminal does not return to the electronic fence area within 10 minutes after crossing the boundary, the early warning module will consider this a serious event that needs attention. When the third data that the crossing time exceeds the 10-minute threshold is detected, the early warning module will immediately activate the early warning mechanism. This mechanism includes multiple levels of response actions to ensure that the crossing event can be handled promptly and effectively. First, the early warning module will trigger the alarm inside the system and send an emergency notification to the management personnel. These notifications can be sent in a variety of ways, such as SMS, email, system messages, etc., so that the management personnel can quickly understand the details of the crossing event. Secondly, the early warning module may be linked with the monitoring equipment or other security systems at the construction site. For example, it can automatically turn on nearby cameras so that the management personnel can view the images of the crossing area in real time; or it can communicate with other security systems (such as access control systems, alarms, etc.) to jointly deal with the crossing event. In addition, the early warning module will also record the detailed information of the crossing event, including the crossing time, location, terminal number, etc., and generate corresponding reports or logs. These records are of great value for subsequent investigation and analysis, helping managers understand the event and take corresponding measures.

[0034] Please refer to Figure 1 In another embodiment, the construction electronic fence system also includes a data analysis module for receiving and processing third data, analyzing the activity trajectory and residence time of construction personnel or vehicles through a statistical analysis algorithm, and generating an abnormal report if the analysis result shows an abnormal behavior pattern.

[0035] In the above embodiment, after receiving the third data, the data analysis module will first perform data cleaning and preprocessing. This process includes removing duplicate data, processing missing values, converting data formats, etc. to ensure the accuracy and consistency of the data. Next, the module will use statistical analysis algorithms to process the cleaned data. For the activity trajectory analysis of construction personnel or vehicles, the data analysis module will focus on their moving paths, speed changes, direction changes and other characteristics. By calculating indicators such as the length, complexity, and frequently visited areas of the trajectory, the module can evaluate the activity range and habits of construction personnel or vehicles. At the same time, combined with timestamp information, the module can also analyze their activity level and movement patterns in different time periods. In terms of residence time analysis, the data analysis module will count the length of stay of construction personnel or vehicles in a specific area. By comparing the differences in residence time in different areas and different time periods, the module can identify which areas are permanent points or hot spots for construction personnel or vehicles. This information is of great significance for optimizing the layout and resource allocation of the construction site. In addition to basic statistical analysis, the data analysis module will also use some more complex algorithms to identify abnormal behavior patterns. For example, the module can compare the actual behavior of construction workers or vehicles with the expected behavior by establishing a behavior model or pattern recognition algorithm. If the actual behavior is significantly different from the expected behavior or exceeds a certain threshold, the module will consider it an abnormal behavior pattern. After detecting the abnormal behavior pattern, the data analysis module will generate corresponding abnormality reports. These reports will record in detail the specific manifestations of the abnormal behavior, the time and location of occurrence, and possible causes. At the same time, the module will also give corresponding handling suggestions or early warning measures based on the severity and urgency of the abnormal behavior.

[0036] Please refer to Figure 1 In another embodiment, the construction electronic fence system has a user management function, which manages user access and operation permissions through preset user permission rules.

[0037] In the above embodiment, a series of user roles and corresponding permission levels are defined, and these permission levels specify in detail what data different roles can access and what operations they can perform. When a user attempts to log in to the system or perform a specific operation, the system will check the user's role and permission, and allow or deny the request based on the preset rules. This role-based permission management strategy ensures that only authorized users can access and operate the key functions and data of the system, thereby effectively preventing unauthorized access and potential security risks.

[0038] Please refer to Figure 1 In another embodiment, the construction electronic fence system has remote monitoring and remote operation functions.

[0039] In the above embodiment, the system uses wired or wireless transmission to transmit real-time data and information of the construction site to the remote monitoring center. In the monitoring center, managers can monitor the status of the electronic fence, personnel and vehicle activities, etc. at the construction site in real time through a special software interface or mobile application. At the same time, the system also supports remote operation functions. Managers can remotely adjust the settings of the electronic fence, start or shut down the early warning mechanism, etc. through the control buttons or instructions on the interface, so as to realize remote management and control of the construction site. This remote monitoring and remote operation method improves management efficiency and reduces the risks of on-site operations.
