Description

Technical Field

[0001] The present invention relates to the technical field of personnel positioning safety management, and in particular to a novel solution for precise personnel positioning and machinery safety management. Background Art

[0002] Port personnel location and machinery safety management are crucial in modern port operations. Advanced IoT technologies, such as Bluetooth positioning and UWB ultra-wideband positioning, enable real-time and accurate tracking of port personnel's locations. This not only facilitates efficient resource allocation but also allows for rapid identification of personnel in emergencies such as fires and landslides, significantly improving rescue efficiency and protecting personnel safety. Furthermore, electronic fences can be set up in specific areas. If personnel stray into a dangerous area, the system will immediately issue an alert to prevent accidents. Machinery safety management encompasses multiple aspects. First, sensors are installed on various large-scale port machinery, such as cranes and loading bridges, to monitor their operating status in real time, including parameters such as temperature, vibration, and stress. This allows for early detection of failure risks, preventive maintenance, and reduced probability of sudden equipment failures. Second, strict machinery operating procedures and procedures are established, and operator proficiency is ensured through training, reducing safety incidents caused by human error. Furthermore, automation technology is being leveraged to enable unmanned operation in some hazardous work scenarios, further ensuring personnel safety, improving the safety and efficiency of overall port operations, and promoting the stable and efficient development of the port area.

[0003] Most existing personnel positioning methods use positioning cards based on LBS, GPS, and Beidou satellite positioning. However, due to the large number of operating machinery and equipment facilities in the port area, the signal is easily interfered with, resulting in reduced accuracy of the positioning card and large deviations. This will cause real-time location information to lag, long warning response time, and low warning accuracy. Summary of the Invention

The high-precision positioning card is equipped with a sensor inside. The location management system can perform trajectory analysis, electronic fence setting and automatic clocking in through a Web interactive interface. The high-precision map system can provide spatial data for positioning by taking high-precision photos, scanning and drawing berths, work areas, roads, yards and green belts within the port area. The Beidou satellite navigation system cooperates with the signal enhancement base station and the high-precision positioning card to transmit the positioning information of personnel and machinery to the location management system and display it in real time through the high-precision map system.

[0010] Preferably, the location management system is internally provided with an automatic clock-in function.

[0011] Preferably, the spatial data acquired by the high-precision map system participates in the positioning calculation process, assisting the Beidou satellite navigation system, signal enhancement base station and high-precision positioning card to complete precise positioning.

[0012] In a second aspect, the present invention provides the following technical solution: a novel management method for personnel precise positioning and machinery safety management solution, comprising the following steps: S1. Use the Beidou satellite navigation system to provide basic positioning signals; S2. Improve positioning accuracy through port machinery enhanced base stations and vehicle-mounted positioning base stations; S3.

Use a high-precision map system to obtain spatial data on berths, work areas, roads, storage yards, and green belts within the port area, and incorporate this data into the positioning calculation process to assist in achieving precise positioning.

[0014] In a fourth aspect, the present invention provides the following technical solution: a readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the above-mentioned management method of a new type of personnel precise positioning and machinery safety management solution.

[0015] The present invention has the following beneficial effects: 1. In the present invention, positioning is performed through a high-precision positioning card using a Beidou dual-frequency navigation chip and UWB ultra-wideband indoor and outdoor integrated positioning technology. The Beidou dual-frequency navigation chip is used to reduce errors such as ionospheric delay. UWB technology is not affected by the complex electromagnetic environment of the port area, and can achieve centimeter-level positioning accuracy, accurately determine the positions of personnel and machinery, and overcome the problem of low accuracy of traditional positioning cards, thereby solving the problem that most personnel positioning methods use positioning cards based on LBS plus GPS plus Beidou satellite positioning. However, due to the large number of operating machinery and equipment facilities in the port area, the signal is easily interfered with, resulting in reduced accuracy of the positioning card and large deviation, which will cause real-time position information to lag, long warning response time, and low warning accuracy.

[0016] 2.

Dangers can be detected and early warnings can be issued in the first place, reducing the risk of casualties. At the same time, the electronic fence function can be used to demarcate restricted areas in advance to prevent people and machinery from entering dangerous areas, thereby reducing the occurrence of safety accidents and ensuring a safe operating environment in the port area.

[0017] 3. In the present invention, through the real-time monitoring and historical trajectory query functions of the location management system, it is convenient for management personnel to understand the distribution and working status of personnel and machinery, flexibly allocate resources according to operational needs, avoid idle or over-concentrated resources, optimize operational processes, reduce waiting time and circuitous routes, and improve the overall operational efficiency of the port area. The automatic clock-in function is associated with operational tasks to ensure that personnel arrive at their posts on time and that various operations are carried out in an orderly manner, thereby improving operational efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention. Example

[0020] Reference Figure 1 In the first embodiment of the present invention, a novel solution for precise personnel positioning and machinery safety management is provided, including a Beidou satellite navigation system, a signal enhancement base station, a high-precision positioning card, a location management system, and a high-precision map system. The Beidou satellite navigation system can provide basic positioning signals, and the signal enhancement base station can improve positioning accuracy through the port machinery enhancement base station and the vehicle-mounted positioning base station. The high-precision positioning card locates personnel and machinery through the Beidou dual-frequency navigation chip and UWB ultra-wideband indoor and outdoor integrated positioning technology. The high-precision positioning card is equipped with a sensor. The location management system can perform trajectory analysis, electronic fence setting, and automatic clocking in through a web interactive interface. The high-precision map system can provide spatial data for positioning by taking high-precision photos, scanning, and mapping berths, work areas, roads, yards, and green belts within the port area. The Beidou satellite navigation system, in conjunction with the signal enhancement base station and the high-precision positioning card, transmits the positioning information of personnel and machinery to the location management system and displays it in real time through the high-precision map system.

[0021] Specifically, the BeiDou satellite navigation system can provide basic satellite signals for the positioning of personnel and machinery, and has a wide signal coverage capability, which can achieve positioning in open outdoor areas such as port areas, ensuring that the positions of personnel and machinery in most outdoor spaces in the port area can be tracked; the basic positioning signals provided by the BeiDou satellite navigation system can be corrected through the signal enhancement base station, reducing the errors caused by factors such as ionospheric and tropospheric delays and multipath effects on the signals, making the positioning results more accurate, and at the same time enhancing the strength of the positioning signal, especially in areas with severe signal obstruction in the port area, such as around tall port machinery equipment and densely populated buildings, ensuring that high-precision positioning cards can stably receive signals, improving the reliability and continuity of positioning, and cooperating with the port machinery enhancement base station and the vehicle-mounted positioning base station to perform signal enhancement at different locations in the port area, making up for the problem of insufficient coverage of BeiDou satellite signals in local areas, so that the positioning system can cover every corner of the port area. Including berths, work areas, yards, etc., to achieve precise positioning of personnel and machinery throughout the port area; through high-precision positioning cards, centimeter-level positioning accuracy can be achieved, and the position of personnel and machinery in the port area can be accurately determined, providing accurate data for safety management and work scheduling. Through UWB technology and Beidou system complementation, effective positioning can be achieved in both indoor work areas and outdoor open areas, ensuring that there are no blind spots in positioning of the entire port area. Once an abnormal state is detected, the information will be quickly transmitted to the location management system, triggering an early warning mechanism to ensure the safety of personnel and machinery; the location management system can receive and display in real time the positioning information of personnel and machinery transmitted by the Beidou satellite navigation system, signal enhancement base stations and high-precision positioning cards, so that managers can grasp their location dynamics at any time; the high-precision map system can provide accurate spatial reference for positioning, so that the positioning information of personnel and machinery can be accurately matched with the actual geographical location of the port area, improving the accuracy and reliability of positioning.

[0022] Reference Figure 1 ,The sensors include air pressure sensor, acceleration sensor, water inlet sensor and chloride ion concentration sensor.

[0023] Specifically, the air pressure sensor can determine whether personnel are in a state of high-altitude work through changes in air pressure. Once it exceeds the safe range, the system will issue an early warning in time to prevent dangers such as falling from heights; the acceleration sensor can sense the movement state of personnel or machinery, identify abnormal behaviors such as falls and collisions, and quickly transmit information to the management system to trigger an alarm to ensure the safety of life and equipment; the water inlet sensor and the chloride ion concentration sensor work together to monitor in real time whether a fall into the sea occurs. When water infiltration is detected or the chloride ion concentration increases abnormally, an alarm will be issued quickly to buy time for rescue.

[0024] Reference Figure 1The air pressure sensor is used to detect situations related to climbing operations, the acceleration sensor is used to identify falls and collisions, and the water inlet sensor and chloride ion concentration sensor are used to monitor falling into the sea.

[0025] Specifically, it can detect various dangerous situations in a timely manner. When personnel may face the risk of falling, stumbling or colliding with objects while working at height, or accidentally fall into the sea, it can quickly send signals to the management system, triggering the early warning mechanism, so that management personnel can take timely measures to reduce the degree of injury and ensure the safety of personnel lives. It can also provide data support for port safety management, help analyze the patterns of accident occurrence, assess operational risks, and formulate more scientific and effective safety management strategies.

[0026] Reference Figure 1 ,The location management system can monitor the location of personnel and machinery in real time, and ,support the query of the historical trajectories of personnel and machinery.

[0027] Specifically, through real-time location monitoring, managers can intuitively grasp the distribution and working status of personnel and machinery, flexibly allocate resources according to operational needs, avoid idle or over-concentrated resources, and improve the overall operational efficiency of the port area; through real-time location monitoring, abnormal situations can be discovered in time, such as personnel or machinery entering dangerous areas, deviating from the prescribed route, etc. The system quickly issues an alarm, and managers take measures to stop it, reducing the probability of safety accidents. Historical trajectory query helps to review accidents after they occur, analyze the causes of accidents, identify safety management loopholes, improve safety measures, and prevent similar accidents from happening again; by analyzing historical trajectories, the movement paths and time consumption of personnel and machinery can be understood, and unreasonable aspects of the operation process can be discovered, such as circuitous paths, long waiting times, etc. Based on these analysis results, the operation process can be optimized, the operation time can be shortened, the operation efficiency can be improved, and the operating costs can be reduced. Reference Figure 1 The location management system is equipped with an electronic fence function. When personnel and machinery enter the restricted area, the system triggers an early warning.

[0028] Specifically, it is possible to demarcate dangerous areas or restricted entry areas in advance, such as high-voltage equipment areas and construction areas in the port area. When personnel or machinery approach or enter these restricted areas, the system will immediately issue an early warning to prevent them from moving forward, thereby avoiding personal injury and mechanical damage, and effectively reducing the incidence of safety accidents such as collisions and electric shocks. At the same time, it can ensure the safety and independence of specific areas, prevent unrelated personnel and machinery from breaking in at will, and interfere with normal operating procedures. For example, electronic fences are set up in berth loading and unloading operation areas to maintain the orderly progress of loading and unloading operations, and avoid interruptions to operations or safety problems due to external interference. It can also provide a powerful means for port safety management, reduce the monitoring pressure of management personnel, and the system automatically monitors and warns, making safety management more timely and accurate, improving the efficiency and level of overall safety management, and facilitating the tracing of intrusion incidents and clarifying responsibilities. Reference Figure 1 , the location management system is equipped with an automatic clock-in function.

[0029] Specifically, by automatically recording the arrival information of personnel in designated areas through the location management system, there is no need for manual operation of the clock-in device, which saves time and avoids the gathering of people and waste of time caused by queuing to clock in. At the same time, it also reduces the manual workload of attendance statistics and improves the efficiency of attendance management. Automatic clock-in is based on precise positioning information and can accurately record the time when personnel arrive and leave the designated area, avoiding situations such as clocking in for others and missing clocking in that may occur with manual clocking in, ensuring that the attendance data is true and reliable, and providing accurate data support for salary calculation, performance evaluation, etc. The automatic clock-in function can be associated with work tasks to help managers understand whether personnel arrive at their work posts on time, facilitate timely grasp of the matching of personnel attendance and work arrangements, and reasonably adjust and optimize the work process to ensure the orderly development of various operations in the port area.

[0030] Reference Figure 1 The spatial data obtained by the high-precision map system participates in the positioning calculation process, assisting the Beidou satellite navigation system, signal enhancement base station and high-precision positioning card to complete precise positioning.

[0031] Specifically, the spatial data of port areas such as berths, roads, and yards provided by the high-precision map system can supplement rich geographic information for positioning calculations. The integration of positioning information from the Beidou satellite navigation system, signal enhancement base stations, and high-precision positioning cards with these data can further eliminate positioning errors, achieve more precise centimeter-level positioning, and more accurately determine the specific locations of personnel and machinery in the port area. In the complex environment of the port area, signals are susceptible to interference. The spatial data of the high-precision map system can assist in judging signal obstruction, reflection, etc., helping the positioning system to acquire and process signals more stably, reduce signal loss and fluctuations, improve the continuity and reliability of positioning, and ensure real-time and stable updates of positioning information. Precise positioning combined with port spatial data can meet the needs of different operating scenarios. For example, in loading and unloading operations, it can accurately grasp the positions of machinery and personnel, optimize operation path planning, and improve operation efficiency. In terms of safety management, it can more accurately judge whether personnel and machinery are in dangerous areas, providing more reliable support for functions such as electronic fences and safety warnings.

[0032] After logging into the system, the location management system can be used for web interaction, historical trajectory query and analysis of vehicles and personnel, electronic fence sealing of entry areas, automatic clocking in at fixed locations, and other operations. Based on the high-precision positioning capability of Beidou satellites, the port machinery enhanced base station and the vehicle-mounted high-precision positioning base station are used in conjunction with high-precision multi-functional personnel positioning cards to achieve full-position real-time supervision of people, vehicles, and machinery. At the same time, combined with high-precision electronic fences, high-precision multi-functional personnel positioning cards can be temporarily distributed to outsiders to provide early warnings to outsiders who break into the safe operating range of machinery and vehicles, thereby reducing the risk of human-machine collisions.

[0033] The realization of these functions requires high-precision port area maps. These maps are created by capturing and scanning berths, work areas, roads, storage yards, green belts, and other elements within the port area. This provides precise spatial information for the port's digital application systems. High-precision map data provides strong data support for accurate positioning and real-time feedback of the location of machinery, vehicles, personnel, and other equipment. Example
