Description

Technical Field

[0001] The present invention relates to a reminder method, and in particular to a nuclear power plant anti-human factor reminder method based on 5G positioning. Background Art

[0002] During the operation of nuclear power plants, it is crucial to ensure the safety of frontline personnel and the correct execution of work tasks. However, due to human factors, there may be loopholes in the execution stage of work order management, which may lead to position deviations or errors when frontline personnel perform their work. In order to solve this problem, nuclear power plants urgently need to introduce precise positioning technology to detect whether the actual execution location of frontline personnel is consistent with the location specified in the work order. In the past precise positioning technology, mainstream hybrid positioning technologies such as 4G LTE cellular and GNSS can achieve an accuracy range of 10 to 12 meters within tens of seconds. However, its accuracy is still not enough to meet the precise positioning requirements in buildings. There is a problem that the position matching accuracy cannot meet the positioning accuracy requirements of nuclear power plants. It is difficult to effectively reduce the possibility of human errors in the execution location of work order tasks, so new technical solutions must be explored. Summary of the invention

[0003] The purpose of the present invention is to provide a nuclear power plant anti-human error reminder method based on 5G positioning in view of the defects of the prior art.

[0011] As described above, a method for preventing human error in a nuclear power plant based on 5G positioning, wherein step 1 includes the following contents:

[0012] Step 1.2: 5g base station receives the signal and forwards it

[0013] The base station forwards the network signal to the location server. The location server calculates the distance between the mobile terminal and multiple current base stations based on the attenuation strength of the mobile terminal network signal transmitted by the base station. The calculation results of more than three base stations are used to accurately locate the mobile terminal using the 5G-based OTDOA technology.

[0018] The mobile terminal sends a data packet to a nearby 5G base station through the TCP-Socket protocol. After being processed by the 5G base station, the data packet is attached with the location information of the base station itself and passed to the location server. The server parses the data packet according to the protocol, and obtains the relative location information of the mobile terminal and the 5G base station, as well as the work order information currently executed by the mobile terminal. The server uses the unique execution work order code transmitted by the mobile terminal as the query condition, accesses the specified work order data storage database, and reads the execution location coordinates in the corresponding work order task.

[0020] The server performs Euclidean distance calculation on the location information of the mobile device and the execution location information provided by the work order, and then compares the calculation result with the corresponding work order location deviation threshold. If the match is successful, the device location is deemed to meet the execution location error range required by the work order, and the user can continue to execute the work order task. If the match fails, the server automatically sends a message warning to remind the front-line executor that the execution location does not match the work order requirements.

[0021] Compared with the prior art, the present invention has the following beneficial effects: the method uses the precise location information of the mobile terminal device provided by 5G positioning to realize the precise positioning of the front-line executors, and by matching with the plant information in the work order task, it can accurately determine whether the location of the mobile terminal device meets the execution location required by the work order:

[0022] (1) Avoiding erroneous execution caused by position mismatch of front-line execution personnel;

[0023] (2) The system can give prompt messages to help users adjust their plans when location matching fails, thus improving work efficiency and accuracy;

[0024] (3) The technical means of the present invention are universal and can be applied to work order task management in various industries, providing a convenient and efficient work order location matching solution.

[0029] With the widespread application of 5G precise positioning technology in the field of nuclear power prevention, existing technologies have been able to achieve the function of real-time detection of the precise indoor and outdoor positions of mobile terminals, and a 5G positioning-based nuclear power plant prevention reminder method has emerged. This method uses 5G precise positioning technology for real-time positioning, and can send early warning notifications and email records to mobile terminals, giving front-line executive personnel timely location warning information.

[0030] To achieve the above-mentioned purpose, the technical solution of the present invention is: a nuclear power plant anti-human factor reminder method based on 5G positioning, which is divided into the following modules, namely, precise positioning module, positioning matching module, and early warning notification module.

[0031] Precise positioning module: With the empowerment of 5G technology for positioning technology, existing 4G positioning technologies such as A-GNSS (Assisted Global Navigation Satellite System) and OTDOA (Observed Time Difference of Arrival) are integrated and enhanced for precise positioning.

[0032] A-GNSS technology assists the positioning process by utilizing additional auxiliary data sources. When performing positioning, mobile devices receive auxiliary data containing additional satellite information, base station location information, and environmental conditions. These data can help devices obtain effective satellite signals faster and perform more accurate positioning calculations. For example, A-GNSS can use the location information provided by the base station to narrow the search range of the device, thereby speeding up the positioning time. In addition, A-GNSS can also use environmental condition data to correct errors in the signal propagation path, thereby improving positioning accuracy. Based on the above characteristics, A-GNSS can play a role in various application scenarios, especially in urban environments and indoor positioning. Since high-rise buildings and dense buildings in cities interfere with the reception of satellite signals, the positioning accuracy of satellite navigation systems such as GPS decreases. A-GNSS technology can overcome these obstacles through auxiliary data and provide more accurate and reliable positioning services.

[0033] OTDOA positioning is a positioning technology based on observed arrival time differences. OTDOA positioning uses the arrival time differences of device signals received by multiple base stations or cells to determine the location of the device by calculating these time differences. When a mobile device sends a signal, it is received by multiple base stations or cells around it, and the timestamp of arrival at each base station is recorded. Since the signal propagation speed is known, the distance difference between the device and each base station can be calculated by calculating the arrival time differences between different base stations. OTDOA positioning requires at least three base stations for measurement, because three points can uniquely determine the location of a device. By using the principle of triangulation and combining the measured value of the arrival time difference, the three-dimensional coordinate position of the device can be calculated. In summary, OTDOA positioning technology has the following advantages: High accuracy: Compared with other positioning technologies, OTDOA positioning can provide higher positioning accuracy. It uses the arrival time differences between multiple base stations for calculation, eliminates errors in the signal propagation path, and thus improves the accuracy of positioning. High coverage: OTDOA positioning technology is suitable for a wide range of wireless communication networks, including urban and rural areas. Comprehensive coverage can be achieved by simply adding a sufficient number of base stations to the network. Low power consumption: Compared with other positioning technologies, OTDOA positioning consumes less battery power on mobile devices. It only requires the device to send a signal and receive the arrival time information returned by the base station, without requiring a lot of calculation and processing.

[0034] The precise positioning module can use the above technical characteristics to realize the precise positioning function of the mobile terminal in complex building complexes such as nuclear power plants.

[0035] Positioning and matching module: Euclidean distance, also known as Euclidean distance, is the most common distance metric, which measures the absolute distance between two points in multidimensional space. Euclidean distance definition: Euclidean distance is a commonly used distance definition, which is the true distance between two points in multidimensional space. After receiving the real-time positioning information from the precise positioning module, the positioning and matching module will read the reference execution location coordinates in the work order or procedure in the corresponding database according to the current unique execution work order code activated by the front-line personnel, and perform Euclidean distance error calculation, and compare the calculated error value with the standard threshold. When the error value meets the requirements, the user can continue to execute the work order task. When the error value exceeds the threshold range, the system will automatically send a message reminder to prompt the user that the device location does not match the work order requirements, and provide corresponding suggestions or adjustment plans.

[0036] Early warning notification module: This module uses the TCP-Socket communication protocol to build a communication channel between the mobile terminal and the server. Among them, Socket is a process communication method that can be used for communication between multiple hosts. The IP address (corresponding to the host) and the Port (corresponding to the process) and the protocol determine a Socket. IP is the exact address of computer hardware in the global network world, for example, 114.114.114.114 is a service address. The Port determines which network program of the computer should be handed over to process the data packet. Protocol is a network communication agreement that both parties must comply with in order to send, receive, and parse data normally. In the TCP / IP protocol family, Socket is an abstract layer used to describe a triple (protocol type, IP address, port number) to represent a unique process on the network. Usually, Socket is called a "socket" or "socket", which is used to uniquely identify the communication port between each process, thereby realizing process-level data transmission. The early warning notification module can connect to other computers or mobile devices through Socket to send or receive data, and can monitor or wait for data changes on other computers or mobile devices.

[0037] A 5G positioning-based nuclear power plant anti-human error reminder method also includes the following components:

[0038] a. Mobile devices and systems: used to connect to the 5G network and obtain the location information of the 5G base station to which the mobile device is connected;

[0039] b. Work order task management system: used to store and manage work order task information, and obtain location information such as factory buildings in work order tasks;

[0040] In summary, if Figure 1As shown, the server receives the location information and work order information of the mobile terminal, calls the precise positioning module to calculate the current location of the mobile terminal in real time based on the location information, and then calls the positioning matching terminal to obtain the reference execution location of the work order information through the unique identification code, calculates the distance according to the Euclidean theorem and compares the threshold information set in the work order. When the comparison is successful, the user continues to execute the work order task; when the match fails, the early warning notification module will automatically send an alarm message and may provide corresponding suggestions or adjustment plans.

[0041] The method comprises the following steps:

[0042] Step 1: If Figure 2 As shown, the mobile device transmits network signals to multiple 5G base stations, and the base stations forward the network signals to the location server. The location server calculates the distance between the mobile terminal and the current multiple base stations based on the attenuation strength of the mobile terminal network signal transmitted by the base station. The 5G-based OTDOA technology is used to accurately locate the mobile terminal based on the calculation results of more than three base stations. If the mobile terminal is inside a building, A-GNSS will be used for auxiliary correction to finally obtain the longitude and latitude coordinates with an accuracy of 1-2m.

[0043] Step 2: The mobile terminal sends a data packet to a nearby 5G base station through the TCP-Socket protocol. After being processed by the 5G base station, the base station's own location information is attached and transmitted to the location server. The server parses the data packet according to the protocol, and obtains the relative location information between the mobile terminal and the 5G base station, as well as the work order information currently executed by the mobile terminal. The server uses the unique execution work order code transmitted by the mobile terminal as the query condition, accesses the specified work order data storage database, and reads the execution location coordinates in the corresponding work order task;

[0044] Step 3: The server calls the positioning matching module to calculate the Euclidean distance between the location information of the mobile device and the location information of the execution location provided by the work order. After obtaining the calculation result, the error is compared with the corresponding work order location deviation threshold. If the match is successful, it is determined that the location of the device meets the execution location error range required by the work order, and the user can continue to execute the work order task. If the match fails, the server automatically sends a message warning to remind the front-line executor that the execution location does not match the work order requirements.

[0045] Compared with traditional execution methods, this method introduces 5G positioning technology to greatly improve the positioning capability of mobile terminals, making it feasible to determine the real-time positioning of front-line executors based on mobile terminals, thereby proposing a method that can effectively solve the human factor problem of executors executing at the wrong execution location.
