[0021] The beneficial effects of the above embodiments are as follows: the mobile terminal connection change control method for industrial equipment scans and searches the industrial scene where the mobile terminal is located, obtains the operating status information of all industrial equipment in the industrial scene, thereby identifying all industrial equipment allowed to be connected to the mobile terminal, and further determines the industrial equipment connected to the mobile terminal, thereby realizing accurate monitoring of the industrial equipment by the mobile terminal; based on the work log of the currently connected industrial equipment, obtains its work task execution status information, thereby adjusting the working status of the industrial equipment to ensure the normal operation of the industrial equipment; also based on the data collection status of the mobile terminal for the currently connected industrial equipment, determines whether the mobile terminal has an abnormal monitoring event for the currently connected industrial equipment, and when an abnormal monitoring event occurs, determines other mobile terminals that can monitor the industrial equipment, and also migrates the mobile terminal's monitoring-related data of the industrial equipment to other mobile terminals, thereby ensuring the continuity and stability of monitoring of the industrial equipment.

[0022] In another embodiment, the industrial scene where the mobile terminal is located is scanned and searched to obtain the operation status information of all industrial devices in the industrial scene; based on the operation status information, all industrial devices allowed to be connected to the mobile terminal are identified, including: Perform a wireless signal scan and search on the industrial scene where the mobile terminal is located to obtain the wireless channel connection status information of all industrial equipment within the industrial scene; based on the wireless channel connection status information, determine whether the external wireless channel of the industrial equipment is in a fully loaded state; if the external wireless communication of the industrial equipment is not in a fully loaded state, determine the industrial equipment as an industrial equipment that is allowed to connect to the mobile terminal.

[0023] The beneficial effect of the above-mentioned embodiment is to scan and search for wireless signals in the industrial scene where the mobile terminal is located, and obtain the wireless channel connection status information of all industrial equipment in the industrial scene. In this way, the status of wireless connection between all industrial equipment in the industrial scene and the outside world can be determined, and whether the external wireless channel of the industrial equipment is already fully loaded (that is, whether the external wireless channel of the industrial equipment has been occupied by a predetermined number of external terminal connections) can be further determined, so that industrial equipment that is not in a fully loaded state can be treated as industrial equipment allowed to connect to the mobile terminal, thereby ensuring the feasibility of the mobile terminal's connection to the industrial equipment.

[0024] In another embodiment, based on the response messages of all working devices allowed to be connected to the mobile terminal, the industrial device connected to the mobile terminal is determined, and a communication channel between the mobile terminal and the corresponding industrial device is established; based on the work log of the currently connected industrial device, the current work task execution status information of the industrial device is determined, so as to adjust the working status of the industrial device, including: Based on the network address information of all industrial devices allowed to connect to the mobile terminal, a connection request is sent to all industrial devices allowed to connect to the mobile terminal, and the response messages of all industrial devices allowed to connect to the mobile terminal regarding the connection request are parsed and processed, and the industrial device that first responds to the connection request is determined as the industrial device connected to the mobile terminal, and a communication channel is established between the mobile terminal and the industrial device that first responds based on their respective access gateway information; Analyze the work log of the currently connected industrial equipment to obtain the current work task execution speed of the currently connected industrial equipment. If the work task execution speed is less than the preset execution speed threshold, increase the computing power resources allocated to the industrial equipment to execute the current work task; otherwise, keep the computing power resources allocated to the industrial equipment to execute the current work task unchanged.

[0025] The beneficial effect of the above embodiment is that, based on the network address information of all industrial devices allowed to connect to the mobile terminal, a connection request is sent to all industrial devices allowed to connect to the mobile terminal, and the industrial device that first responds to the connection request is used as the industrial device connected to the mobile terminal, and based on the access gateway information of the mobile terminal and the first responding industrial device, a communication channel is constructed between the two to ensure the connection exclusivity between the mobile terminal and the corresponding industrial device. In addition, the work log of the currently connected industrial device is analyzed to obtain the current work task execution speed of the currently connected industrial device, so as to accurately adjust the working state of the industrial device so that the industrial device can quickly and stably complete the corresponding work task.

[0026] In another embodiment, based on the data collection status of the mobile terminal for the currently connected industrial equipment, it is determined whether the mobile terminal has an abnormal monitoring event for the currently connected industrial equipment; when an abnormal monitoring event occurs, other mobile terminals that can monitor the industrial equipment are determined, including: Obtaining the data reading speed of the mobile terminal for the currently connected industrial equipment and the storage speed of the read data; if the data reading speed is less than a preset reading speed threshold and the storage speed is less than a preset storage speed threshold, determining that the mobile terminal has a monitoring abnormality event for the currently connected industrial equipment; otherwise, determining that the mobile terminal has not a monitoring abnormality event for the currently connected industrial equipment; When an abnormal monitoring event occurs, all other mobile terminals within the industrial scene are identified and processed, so that other mobile terminals with the largest idle computing resources can be used as other mobile terminals that can monitor the industrial equipment.

[0027] The beneficial effect of the above embodiment is to obtain the data reading speed of the mobile terminal for the currently connected industrial equipment and the storage speed of the read data, and compare the data reading speed and the storage speed with the threshold value, so as to accurately judge whether the mobile terminal has a monitoring abnormality event for the currently connected industrial equipment. In addition, when a monitoring abnormality event occurs, all other mobile terminals in the industrial scene are identified and processed, so that other mobile terminals with the largest idle computing power resources are used as other mobile terminals that can monitor the industrial equipment, so as to ensure that the industrial equipment continues to be monitored by the mobile terminal with the best performance.

[0028] In another embodiment, when the mobile terminal does not have an abnormal monitoring event on the currently connected industrial device, the operating state between the mobile terminal and the currently connected industrial device is determined using the data reading speed and the storage speed, including: When the mobile terminal does not have an abnormal monitoring event on the currently connected industrial equipment, the data reading speed of the mobile terminal on the currently connected industrial equipment and the storage speed of the read data are retrieved; Obtaining an operation quality evaluation coefficient between the mobile terminal and the currently connected industrial equipment by using the data reading speed of the mobile terminal for the currently connected industrial equipment and the storage speed of the read data; The operation quality evaluation coefficient is obtained by the following formula: Where Q represents the operation quality evaluation coefficient, n represents the number of data readings; X 01i represents the data reading speed corresponding to the i-th data reading; X 02i represents the data storage speed corresponding to the i-th data storage; X 01bIndicates the standard deviation of data reading speed corresponding to n data readings; X 02b represents the standard deviation of data storage speed corresponding to n data readings; X 01y Indicates the preset reading speed threshold; X 02y represents a preset storage speed threshold; s represents an evaluation component, and the evaluation component is obtained by the following formula: Among them, s represents the evaluation component; m represents the total number of data storage; X 02j represents the data storage speed corresponding to the jth data storage in the total number of data storage times; 02mb represents the standard deviation of data storage speed corresponding to m data storage times; X 01b Indicates the standard deviation of data reading speed corresponding to n data readings; X 02b represents the standard deviation of data storage speed corresponding to n data readings; X 01y Indicates the preset reading speed threshold; X 02y Indicates the preset storage speed threshold; Comparing the operation quality evaluation coefficient with a preset evaluation coefficient threshold; When the operation quality evaluation coefficient is lower than a preset evaluation coefficient threshold, it is determined that there is an abnormality in the operation status between the mobile terminal and the currently connected industrial equipment, and an abnormality warning is issued.

[0029] The beneficial effect of the above embodiment is that the technical solution can actively determine the operating status when the mobile terminal does not have an abnormal monitoring event for the currently connected industrial equipment. By real-time monitoring of data reading speed and storage speed, once these key indicators reflect potential operating problems, the system can issue abnormal warnings in time to prevent possible failures or performance degradation. By introducing the operation quality evaluation coefficient Q, the scheme can comprehensively consider the data reading speed, storage speed and its standard deviation, as well as the comparison with the preset threshold, to accurately evaluate the operating status between the mobile terminal and the industrial equipment. This comprehensive consideration method can more comprehensively reflect the overall performance and stability of the system than a single indicator. The calculation of the evaluation coefficient Q takes into account the results of multiple data reading and storage, as well as the standard deviation of these results, which makes the evaluation more dynamic and accurate. The use of standard deviation reflects the volatility of data reading and storage speed, which helps to identify potential unstable factors. When the operation quality evaluation coefficient is lower than the preset evaluation coefficient threshold, the system automatically determines that there is an abnormality in the operating status and issues an early warning. This mechanism reduces the need for manual monitoring and improves the efficiency and accuracy of early warning. By timely warning of potential operational anomalies, this technical solution helps enterprises take measures in advance, such as adjusting equipment configuration, optimizing network settings, or performing necessary maintenance, thereby avoiding adverse consequences such as production interruptions or data loss and optimizing resource usage and allocation. Long-term application of this technical solution can significantly improve the reliability and stability of communication between industrial equipment and mobile terminals, providing strong support for industrial automation and remote monitoring.

[0030] In summary, this technical solution effectively improves the reliability and stability of communication between industrial equipment and mobile terminals through mechanisms such as real-time monitoring, accurate evaluation, dynamic adaptation and efficient early warning, providing strong technical support for industrial automation and remote monitoring.

[0041] In another embodiment, when the mobile terminal does not have an abnormal monitoring event on the currently connected industrial device, the operating state between the mobile terminal and the currently connected industrial device is determined using the data reading speed and the storage speed, including: When the mobile terminal does not have an abnormal monitoring event on the currently connected industrial equipment, the data reading speed of the mobile terminal on the currently connected industrial equipment and the storage speed of the read data are retrieved; Obtaining an operation quality evaluation coefficient between the mobile terminal and the currently connected industrial equipment by using the data reading speed of the mobile terminal for the currently connected industrial equipment and the storage speed of the read data; The operation quality evaluation coefficient is obtained by the following formula: Where Q represents the operation quality evaluation coefficient, n represents the number of data readings; X 01i represents the data reading speed corresponding to the i-th data reading; X 02i represents the data storage speed corresponding to the i-th data storage; X 01b Indicates the standard deviation of data reading speed corresponding to n data readings; X 02b represents the standard deviation of data storage speed corresponding to n data readings; X 01y Indicates the preset reading speed threshold; X 02y represents a preset storage speed threshold; s represents an evaluation component, and the evaluation component is obtained by the following formula: Among them, s represents the evaluation component; m represents the total number of data storage; X 02j represents the data storage speed corresponding to the jth data storage in the total number of data storage times; 02mbrepresents the standard deviation of data storage speed corresponding to m data storage times; X 01b Indicates the standard deviation of data reading speed corresponding to n data readings; X 02b represents the standard deviation of data storage speed corresponding to n data readings; X 01y Indicates the preset reading speed threshold; X 02y Indicates the preset storage speed threshold; Comparing the operation quality evaluation coefficient with a preset evaluation coefficient threshold; When the operation quality evaluation coefficient is lower than a preset evaluation coefficient threshold, it is determined that there is an abnormality in the operation status between the mobile terminal and the currently connected industrial equipment, and an abnormality warning is issued.

[0042] The beneficial effect of the above embodiment is that the technical solution can actively determine the operating status when the mobile terminal does not have an abnormal monitoring event for the currently connected industrial equipment. By real-time monitoring of data reading speed and storage speed, once these key indicators reflect potential operating problems, the system can issue abnormal warnings in time to prevent possible failures or performance degradation. By introducing the operation quality evaluation coefficient Q, the scheme can comprehensively consider the data reading speed, storage speed and its standard deviation, as well as the comparison with the preset threshold, to accurately evaluate the operating status between the mobile terminal and the industrial equipment. This comprehensive consideration method can more comprehensively reflect the overall performance and stability of the system than a single indicator. The calculation of the evaluation coefficient Q takes into account the results of multiple data reading and storage, as well as the standard deviation of these results, which makes the evaluation more dynamic and accurate. The use of standard deviation reflects the volatility of data reading and storage speed, which helps to identify potential unstable factors. When the operation quality evaluation coefficient is lower than the preset evaluation coefficient threshold, the system automatically determines that there is an abnormality in the operating status and issues an early warning. This mechanism reduces the need for manual monitoring and improves the efficiency and accuracy of early warning. By timely warning of potential operational anomalies, this technical solution helps enterprises take measures in advance, such as adjusting equipment configuration, optimizing network settings, or performing necessary maintenance, thereby avoiding adverse consequences such as production interruptions or data loss and optimizing resource usage and allocation. Long-term application of this technical solution can significantly improve the reliability and stability of communication between industrial equipment and mobile terminals, providing strong support for industrial automation and remote monitoring.

[0043] In summary, this technical solution effectively improves the reliability and stability of communication between industrial equipment and mobile terminals through mechanisms such as real-time monitoring, accurate evaluation, dynamic adaptation and efficient early warning, providing strong technical support for industrial automation and remote monitoring.

[0044] In another embodiment, the data migration module is used to migrate the monitoring-related data of the mobile terminal on the industrial equipment to the other mobile terminal after establishing the connection relationship between the other mobile terminal and the industrial equipment based on the network connection status of the other mobile terminal, including: After building a communication channel between the other mobile terminal and the industrial device based on the access gateway information of the other mobile terminal, the monitoring-related data of the industrial device formed by the mobile terminal is migrated as a whole to the corresponding storage space inside the other mobile terminal.

[0045] The beneficial effect of the above embodiment is that, based on the access gateway information of the other mobile terminal, a communication channel is constructed between the other mobile terminal and the industrial equipment, a stable switching connection between the industrial equipment and other mobile terminals is achieved, and then the monitoring-related data of the industrial equipment formed by the mobile terminal is migrated as a whole to the corresponding storage space inside the other mobile terminal, thereby ensuring the sustainable monitoring of the industrial equipment by the other mobile terminal.

[0046] In general, the mobile terminal connection change control method and system for industrial equipment scans and searches the industrial scene where the mobile terminal is located, obtains the operating status information of all industrial equipment in the industrial scene, thereby identifying all industrial equipment allowed to be connected to the mobile terminal, and further determines the industrial equipment connected to the mobile terminal, so as to realize accurate monitoring of the industrial equipment by the mobile terminal; based on the work log of the currently connected industrial equipment, obtains its work task execution status information, so as to adjust the working status of the industrial equipment and ensure the normal operation of the industrial equipment; also based on the data collection status of the mobile terminal for the currently connected industrial equipment, determines whether the mobile terminal has an abnormal monitoring event for the currently connected industrial equipment, and when an abnormal monitoring event occurs, determines other mobile terminals that can monitor the industrial equipment, and also migrates the mobile terminal's monitoring-related data of the industrial equipment to other mobile terminals, so as to ensure the continuity and stability of the monitoring of the industrial equipment.
