[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0030] Example 1, reference Figure 1 , as an embodiment of the present invention, provides a field virtual bus signal transmission method for transmission tower grounding measurement, comprising:

[0031] S1: Collect status data of each first object and establish a distribution architecture.

[0032] The state data includes data that can reflect the working state of the first object and the security state of the first object itself. Establishing a distributed architecture includes deploying distributed nodes and performing sharding processing on the state data; the distributed nodes include nodes that can perform flow operations on the state data of the first object; the sharding processing includes sharding the state data of the first object and performing distributed processing on the sharded data.

[0033] In this embodiment, the first object is the transmission tower, and the second object is the monitoring center. The monitoring center receives the grounding signal data from the transmission tower, aggregates, analyzes and stores the data through a distributed architecture, and realizes remote real-time monitoring of the status of all transmission towers. In particular, corresponding measures can be taken quickly in abnormal situations to ensure the safety and stability of the power grid.

[0034] In an optional embodiment, the first object may also be a traffic light at an intersection, a traffic camera or a road sensor, which collects traffic flow, traffic light status and accident information in real time. The second object is a traffic management center, which receives data from the first object, analyzes road congestion, traffic accidents and other conditions through a distributed architecture, and implements remote monitoring. When traffic is abnormal, the system quickly sends an early warning and automatically adjusts the timing of traffic lights or dispatches traffic police to optimize traffic flow.

[0035] Furthermore, the first object is the equipment on the industrial site, which collects the equipment's status information such as temperature, pressure, vibration, etc. The second object is the factory monitoring center, which receives equipment status data and monitors the equipment's operating status and health status through distributed nodes. When an abnormality is detected in the equipment, the system can immediately issue an alarm to help managers make maintenance decisions quickly and avoid production stagnation or safety risks caused by equipment failure.

[0036] Furthermore, the first object is the environmental sensor sites distributed in various places, which collect data such as air quality, humidity, and temperature. The second object is the environmental monitoring center, which receives data from distributed sensors and identifies environmental conditions such as pollutant concentration and abnormal temperature through distributed analysis. When excessive pollution or extreme weather occurs, the monitoring center sends an early warning in a timely manner and coordinates the environmental governance department to take emergency measures to ensure public safety.

[0037] The first object is the temperature control, security, fire protection and other equipment in the building, which collects information such as indoor temperature, smoke, door and window status, etc. The second object is the building control center, which receives data from various devices and realizes real-time monitoring of temperature control, security and fire protection through a distributed architecture. When abnormal conditions such as fire or intrusion are detected, the system automatically issues an alarm, notifies management personnel and controls the activation of fire protection facilities to ensure building safety.

[0038] Furthermore, by collecting the status data of each "first object" and establishing a distributed architecture, distributed real-time monitoring is achieved, thereby reducing the burden of centralized processing and improving the real-time performance and processing efficiency of data. Distributed nodes perform data sharding and flow operations, enabling the system to respond quickly to abnormal situations, avoiding bottlenecks caused by centralized processing, and significantly improving the reliability and response speed of the system. At the same time, this architecture is highly adaptable and suitable for a variety of scenarios (such as power transmission monitoring, traffic management, industrial equipment monitoring, etc.) and large-scale deployment, ensuring the scalability of the system. In addition, the flow and storage functions of distributed nodes enhance the security and data integrity of the system, and ensure that data is not lost even if a failure occurs during transmission. The distributed architecture also generates real-time status feedback through local analysis, enabling the monitoring center to make quick decisions and precise control, such as adjusting signals, starting fire protection or maintenance equipment, improving the security of the system and its ability to respond to abnormal situations.

[0039] S2: Monitor the status of the first object through the distributed architecture.

[0040] Monitoring the state of the first object includes performing local analysis on each first object through a distributed node, and merging each local analysis result to form a complete state monitoring result.

[0041] Furthermore, by using distributed nodes to perform local analysis on each "first object" and merging the local analysis results of each node to form a complete status monitoring result, the accuracy and comprehensiveness of monitoring can be significantly improved, and missed reports and false reports can be avoided. Distributed computing reduces the system's network load and central processing pressure, and is particularly suitable for large-scale monitoring scenarios, improving the system's operating efficiency. Local analysis can quickly identify abnormal situations and shorten abnormal response time, thereby enhancing the system's real-time response capability. In addition, the distributed analysis and merging mechanism improves the system's stability and fault tolerance, and even if some nodes fail, it does not affect the overall monitoring effect. Through detailed local analysis, the system can monitor the status of the first object in multiple dimensions, provide comprehensive status information, and enable the monitoring center to manage and control each object more accurately.

[0042] S3: Transferring the state of the first object to the second object.

[0043] Transmitting the state of the first object to the second object includes, according to the state of the first object, selecting a transmission link to transmit to the second object. Selecting a transmission link to transmit to the second object includes, according to different transmission links, selecting different encryption schemes, generating corresponding encryption keys and transmitting to the second object.

[0044] In this embodiment, the transmission link includes, but is not limited to, a periodic transmission link and a real-time transmission link.

[0045] In an optional embodiment, it can be a priority transmission link. When multiple monitoring data types coexist, the transmission priority is set according to the importance and urgency of the data. For example, when a serious abnormality is detected in the grounding signal of a transmission tower, the priority transmission link can ensure that the data is transmitted to the monitoring center first, avoiding the delay of key data under high load and ensuring timely processing of high-priority events.

[0046] Furthermore, by setting up redundant links, the system automatically switches to the backup link when a transmission failure is detected. When the main link is interrupted due to severe weather or environmental interference, the redundant link can continue to transmit grounding signal data to ensure uninterrupted monitoring.

[0047] Furthermore, priority transmission links are used to ensure the priority transmission of key data, improve the real-time response capability of the system, and enable important information to reach the monitoring center in a timely manner under high load conditions, avoiding security risks caused by delays. At the same time, the setting of redundant links enhances the reliability of transmission, and can automatically switch when the main link is interrupted, ensuring the continuity of data transmission and the stable operation of the system. The corresponding encryption scheme is used under different transmission links to effectively protect the security of data during transmission and prevent information leakage. In addition, the flexible link selection mechanism enables the system to adaptively adjust the transmission mode according to the data type and environmental changes, meet the monitoring needs of multiple scenarios, and improve the adaptability and flexibility of the system. Ultimately, this mechanism ensures the priority processing of key events, improves the decision-making speed and emergency response capabilities of the monitoring center, and provides important support for the safe and efficient operation of the system.

[0048] Embodiment 2 is an embodiment of the present invention, which provides a field virtual bus signal transmission system for transmission tower grounding measurement, including:

[0049] like Figure 2 As shown, a field virtual bus signal transmission system for grounding measurement of transmission towers includes a monitoring center, and the monitoring center is communicatively connected with an information acquisition module, an information processing module, an encryption transmission module, and an information analysis module;

[0050] The information collection module is composed of a plurality of information collection terminals, which are arranged at the location of the transmission tower pole and are used to collect the grounding signal of the transmission tower pole in real time. The specific process includes:

[0051] The location of the transmission tower pole is obtained, a corresponding information collection terminal is set at each transmission tower pole, and the location of each transmission tower pole is recorded as an information transmission node. The information collection terminal includes an information collection unit, an information transmission unit and an information storage unit.

[0052] The grounding signal of the transmission tower is acquired in real time through the information acquisition unit.

[0053] The information storage unit is used to temporarily store the acquired grounding signal of the transmission tower.

[0054] The information transmission unit is provided with a corresponding information transmission range, and there is at least one other information transmission unit within the information transmission range of the information transmission unit, and the obtained grounding signal of the transmission tower is transmitted through the information transmission unit.

[0055] The information processing module is used to process the acquired grounding signal of the transmission tower pole to obtain a corresponding signal data packet to be transmitted. The specific process includes:

[0056] Construct an information transmission network based on the location of information transmission nodes.

[0057] Corresponding node attribute information is associated with each information transmission node, and the node attribute information includes information transmission frequency and node identity sequence.

[0058] The information transmission network is divided into several areas, and a distributed information cluster node is set in each area. The set distributed information cluster node is communicatively connected with each information transmission node in the area.

[0059] A two-dimensional coordinate system of time with respect to ground signal strength is constructed in the distributed information cluster node. A corresponding signal strength variation curve is generated according to the ground signal obtained by each information transmission node in communication connection with the distributed information cluster node. The generated signal strength variation curve is mapped into the two-dimensional coordinate system. A corresponding signal strength threshold range and information upload period are set in the two-dimensional coordinate system.

[0060] The generated signal strength variation curve is compared with the signal strength threshold range, a corresponding signal data packet to be transmitted is generated according to the comparison result, and the generated signal data packet to be transmitted is backed up in the information storage unit.

[0061] It should be further explained that, in a specific implementation process, the generated signal strength change curve is compared with the signal strength threshold range, and the process of generating a corresponding signal data packet to be transmitted according to the comparison result includes:

[0062] When the signal strength variation curve is within the signal strength threshold range, it indicates that the grounding signal of the tower where the corresponding information transmission node is located is normal.

[0063] When the grounding signal of the tower is normal, the obtained grounding signal is periodically summarized according to the set information upload cycle, a signal data packet to be transmitted is generated, and a periodic transmission link is constructed according to the node attribute information. The signal data packet to be transmitted is transmitted to the distributed information cluster node that is communicatively connected to the information transmission node through the constructed periodic transmission link.

[0064] When the signal strength variation curve is not within the signal strength threshold range, it indicates that the grounding signal of the tower where the corresponding information transmission node is located is abnormal, and the corresponding signal strength variation curve is marked.

[0065] When the grounding signal of the tower is abnormal, a real-time transmission link is constructed according to the node attribute information, and the marked signal strength change curve is transmitted to the distributed information cluster node that is communicatively connected to the information transmission node through the constructed real-time transmission link.

[0066] The encryption transmission module is used to encrypt and transmit the signal data packet to be transmitted, and the specific process includes:

[0067] When the information transmission node is connected to the distributed information cluster node through the periodic transmission link communication, the periodic transmission link is encrypted through the first encryption scheme;

[0068] It should be further explained that, in a specific implementation process, the process of encrypting the communication of the periodic transmission link by using the first encryption scheme includes:

[0069] Node attribute information of the information transmission node is obtained, and a node identity sequence in the node attribute information is used as a first sequence.

[0070] According to the time span of the information upload period corresponding to the signal data packet to be transmitted, a corresponding time span sequence is generated, and the generated time span sequence is used as the second sequence; it should be further explained that in the specific implementation process, the time span is specifically: when the start time of the information upload period is t1 and the end time is t2, the time span is from t1 to t2.

[0071] A third sequence is generated according to the information transmission frequency in the node attribute information.

[0072] It should be further explained that, in a specific implementation process, the unit codes constituting the first sequence, the second sequence and the third sequence have the same system.

[0073] The first sequence, the second sequence and the third sequence are combined to obtain an information verification sequence.

[0074] The signal data packet to be transmitted is converted into a data stream, and the data stream converted from the signal data packet to be transmitted is encrypted by the obtained information verification sequence to obtain the encrypted data stream and the corresponding data key, and the obtained data key is associated with the information verification sequence.

[0075] The information verification sequence, data key and encrypted data stream are transmitted to the corresponding distributed information cluster nodes in sequence through the periodic transmission link.

[0076] The distributed information cluster node uploads the received data key to the monitoring center for storage.

[0077] During the specific implementation process, when the tower grounding signal is normal, the signal data packets to be transmitted in each information upload cycle are encrypted to ensure that the signal data packets to be transmitted through the periodic transmission link will not be lost, thereby making the distributed information cluster nodes received by the distributed information cluster nodes more complete.

[0078] When the information transmission node is connected to the distributed information cluster node through the real-time transmission link communication, the periodic transmission link is encrypted through the second encryption scheme.

[0079] It should be further explained that, in a specific implementation process, the process of encrypting the communication of the periodic transmission link by the second encryption scheme includes:

[0080] Node attribute information of the information transmission node is obtained, and a node identity sequence in the node attribute information is used as a first sequence.

[0081] According to the time when the grounding signal of the tower pole is abnormal, a corresponding time sequence is generated, and the generated time sequence is used as the second sequence.

[0082] A third sequence is generated according to the information transmission frequency in the node attribute information.

[0083] The first sequence, the second sequence and the third sequence are combined to obtain a transmission associated sequence.

[0084] The transmission association sequence is converted into a corresponding base according to the information transmission frequency in the node attribute information, and the obtained base conversion result is used as the encryption key.

[0085] After the real-time transmission link is encrypted by the obtained transmission association sequence, the marked signal strength change curve is transmitted to the corresponding distributed information cluster node through the real-time transmission link after the communication encryption is completed.

[0086] It should be further explained that, in the specific implementation process, the real-time transmission link is encrypted through the encryption key, so that the real-time transmission link is more stable during the real-time transmission of abnormal grounding signals, thereby ensuring that the distributed information cluster nodes receive the real-time grounding signals more quickly and stably.

[0087] It should be further explained that, in the specific implementation process, the information parsing module is used to parse the encrypted data stream received by the distributed information cluster node, and the specific process includes:

[0088] The information verification sequence received by the distributed information cluster node is read, and the data key associated with the information verification sequence of the monitoring center is retrieved according to the read information verification sequence.

[0089] According to the retrieved data key, the encrypted data stream received by the distributed information cluster node is parsed. After the parsed data is uploaded to the monitoring center, the data key in the monitoring center is cleared and a feedback instruction is generated.

[0090] The feedback instruction is sent to the corresponding information transmission node, and the information transmission node clears the corresponding signal data packet to be transmitted backed up in the information storage unit according to the feedback instruction.

[0091] Embodiment 3, an embodiment of the present invention provides a field virtual bus signal transmission system for transmission tower grounding measurement, comprising:

[0092] The status data of each first object is collected and a distribution architecture is established.

[0093] A state of a first object is monitored via a distributed architecture.

[0094] Transfers the state of a first object to a second object.

[0095] If the functions are implemented in the form of software functional units and sold or used as independent products, they can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of the present invention, or the part that contributes to the prior art or the part of the technical solution, can be embodied in the form of a software product. The computer software product is stored in a storage medium, including several instructions for a computer device (which can be a personal computer, a server, or a network device, etc.) to perform all or part of the steps of the method described in each embodiment of the present invention. The aforementioned storage medium includes: U disk, mobile hard disk, read-only memory (ROM, Read-Only Memory), random access memory (RAM, Random Access Memory), disk or optical disk, etc., which can store program code.

[0096] The logic and / or steps represented in the flowchart or otherwise described herein, for example, can be considered as an ordered list of executable instructions for implementing logical functions, and can be embodied in any computer-readable medium for use by an instruction execution system, device or apparatus (such as a computer-based system, a system including a processor, or other system that can fetch instructions from an instruction execution system, device or apparatus and execute instructions), or in conjunction with such instruction execution systems, devices or apparatuses. For the purposes of this specification, "computer-readable medium" can be any device that can contain, store, communicate, propagate or transmit a program for use by an instruction execution system, device or apparatus, or in conjunction with such instruction execution systems, devices or apparatuses.

[0097] More specific examples of computer-readable media (a non-exhaustive list) include the following: an electrical connection with one or more wires (electronic device), a portable computer disk case (magnetic device), a random access memory (RAM), a read-only memory (ROM), an erasable and programmable read-only memory (EPROM or flash memory), an optical fiber device, and a portable compact disk read-only memory (CDROM). In addition, the computer-readable medium may even be a paper or other suitable medium on which the program is printed, since the program may be obtained electronically, for example, by optically scanning the paper or other medium, followed by editing, deciphering or, if necessary, processing in another suitable manner, and then stored in a computer memory.

[0098] It should be understood that the various parts of the present invention can be implemented by hardware, software, firmware or a combination thereof. In the above-mentioned embodiments, a plurality of steps or methods can be implemented by software or firmware stored in a memory and executed by a suitable instruction execution system. For example, if implemented by hardware, as in another embodiment, it can be implemented by any one of the following technologies known in the art or their combination: a discrete logic circuit having a logic gate circuit for implementing a logic function for a data signal, a dedicated integrated circuit having a suitable combination of logic gate circuits, a programmable gate array (PGA), a field programmable gate array (FPGA), etc.

[0099] In Example 4, six typical transmission towers are selected as the "first object", and status data acquisition equipment is installed on each tower to monitor the grounding resistance, current, voltage and other data closely related to the working and safety status of the tower. The experimental system is equipped with an information acquisition module, an information processing module, an encryption transmission module and an information analysis module. The experiment is carried out in a simulated environment using actual transmission tower equipment to ensure the rationality and authenticity of the data, so as to reflect the application effect of the present invention in a real scenario.

[0100] In the experiment, first, the status data (ground resistance, current, voltage, etc.) of each transmission tower is collected regularly through the information collection module, and a distributed architecture for data flow is established between distributed nodes. In this process, data is collected at fixed time intervals (every 5 minutes), and according to monitoring requirements, the status data is processed in slices and transmitted to distributed nodes. The slice processing processes each data fragment into a 5-minute time period so that each distributed node can perform preliminary analysis on the small fragment of data. At the same time, the warning thresholds for ground resistance and current are set in the node: when the ground resistance exceeds 0.5Ω or the current exceeds 10A, the data will be automatically marked as abnormal.

[0101] In the local analysis phase, each distributed node uses a weighted average algorithm to generate an average state value for each segment of data and compares it with the preset range under normal conditions. In the case where a data segment exceeds the warning threshold, the system automatically selects a priority transmission link through the encryption transmission module to ensure that these abnormal state data are transmitted to the monitoring center as soon as possible. The encryption transmission module uses AES-256 and RSA algorithms to encrypt data. Periodic data is transmitted through AES-256, while abnormal data is transmitted after being encrypted through a real-time link and RSA algorithm. Each distributed node generates a unique encryption key before transmission and transmits the key to the monitoring center so that the monitoring center can complete decryption and data analysis.

[0102] In the monitoring center, after receiving the data, the information analysis module uses the transmitted encryption key to decrypt, analyze the data and generate the corresponding alarm instructions. After the analysis is completed, the monitoring center automatically clears the temporary storage data of the node to avoid repeated transmission. By combining and analyzing all the data, the monitoring center can timely detect the abnormal conditions of each transmission tower. Especially when multiple nodes are detected to be abnormal, the real-time early warning system can actively send an alarm to prompt the operation and maintenance personnel to deal with it in time to ensure the safety and stability of the power grid. The experimental data is shown in Table 1.

[0103] Table 1 Experimental data table

[0104] parameter Tower 1 Tower 2 Tower 3 Tower 4 Tower 5 Tower 6 Ground resistance(Ω) 0.35 0.38 0.41 0.53 0.45 0.47 Current (A) 8 9 11 10 7 8 Voltage(kV) 220 220 220 210 230 225 Transmission delay (ms) 80 85 75 90 88 82 Data encryption type AES-256 AES-256 RSA RSA AES-256 AES-256 Warning status normal normal abnormal abnormal normal normal Transmission link type Periodic transmission Periodic transmission Real-time transmission Real-time transmission Periodic transmission Periodic transmission

[0105] Among them, it can be seen from the experimental data that the distributed architecture and dynamic transmission link selection strategy of the present invention have significant advantages in transmission tower monitoring. First, the data collection and transmission of ground resistance and current show efficient abnormality detection capabilities. For example, the ground resistance and current of towers 3 and 4 both exceed the set warning threshold. The system automatically selects the real-time transmission link to ensure that key data is transmitted to the monitoring center first under abnormal circumstances, shortening the abnormal data transmission time and ensuring timely response to faults.

[0106] Secondly, the distributed nodes in the present invention perform local analysis and sharding on the data, which greatly reduces the pressure of central processing and improves the processing efficiency and reliability of the system. For example, through local node screening and preprocessing, the system realizes distributed early warning status judgment during the transmission process, effectively reducing the computing pressure of the monitoring center. In addition, through the combined encryption mechanism of AES-256 and RSA algorithms, the present invention further improves the adaptability and flexibility of the system while ensuring the security of data transmission. The data table shows that for normal state data, the system uses the periodic transmission link of AES-256, while for abnormal state data, it uses more secure RSA encryption and real-time link transmission. This encryption and dynamic adjustment of the link ensures the security and timeliness of the transmission process.

[0107] Compared with the existing centralized power transmission monitoring system, the innovation of the present invention is mainly reflected in the distributed node processing and flexible transmission link selection. Centralized systems usually require high bandwidth support, and when anomalies occur, they are often prone to transmission delays and packet loss due to data backlogs. The present invention not only reduces the transmission load through the design of sharding processing and priority links, but also ensures the priority transmission of key data. In addition, the system adapts to the transmission requirements of different types of data by dynamically selecting encryption schemes and transmission links, thereby improving the security and practicality of the system. Therefore, the experimental results show that the distributed structure and transmission method of the present invention have significant advantages in abnormal response, data security and monitoring efficiency, and can effectively overcome the shortcomings of traditional systems in transmission tower monitoring.

[0108] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
