Description

Technical Field

[0001] The present invention relates to the technical field of remote positioning control, and in particular to a real-time information monitoring method, device and system based on dispatching and monitoring an emergency power supply vehicle. Background Art

[0002] As an important technical support system for power grid operation control and dispatching production management, the D5000 master station system mainly performs real-time monitoring, dispatching planning, safety verification, and dispatching management of the power grid. The power generation vehicle is a special vehicle equipped with a power supply device, which is mainly used for power generation, equipment maintenance, conference support, field operations, etc. Under normal circumstances, it is impossible to obtain the operating data of the power generation vehicle in real time through the D5000 master station, such as output power, voltage, current, etc.

[0003] In terms of data transmission, the operation and maintenance personnel need to arrive at the working location of the power generation vehicle to make a judgment on whether the power generation vehicle has any faults or hidden dangers, and cannot provide timely repair and maintenance suggestions to the operation and maintenance personnel. This not only affects the extension of the service life of the power generation vehicle, but also fails to ensure the safe and stable operation of the power grid and avoid accidents.

[0004] In the existing power generation vehicle monitoring system, there is usually a lack of real-time and accurate positioning functions. Operation and maintenance personnel are often unable to obtain the specific location information of the power generation vehicle in real time, which means that in emergency situations that require rapid response, the operation and maintenance personnel may need to spend extra time to find the location of the power generation vehicle. In addition, when the power generation vehicle is in a remote area or an area with poor signal, the accuracy and reliability of the positioning information are greatly reduced, further increasing the difficulty and cost of operation and maintenance.

[0005] Traditional power generation vehicle monitoring systems have many limitations in remote adjustment. On the one hand, due to the differences in control systems and communication protocols of different power generation vehicles, the compatibility and versatility of remote adjustment are poor. On the other hand, existing remote adjustment methods often rely on wired connections or inefficient communication methods, which not only limits the real-time adjustment, but also increases the complexity and cost of operation. In addition, when a power generation vehicle fails or needs to adjust settings, technicians usually need to be dispatched to the site for manual operation, which not only wastes human resources but also prolongs the time for fault recovery. Summary of the invention

[0006] In view of the above-mentioned problems, the present invention is proposed.

[0007] Therefore, the technical problem solved by the present invention is that the operation and maintenance personnel need to arrive at the working place of the power generation vehicle to judge whether the power generation vehicle has any faults and hidden dangers, and it is impossible to provide maintenance and repair suggestions to the operation and maintenance personnel in time. The operating status and data of the emergency power supply vehicle may only be monitored by non-real-time means or equipment, lacking an intuitive visual interface and real-time monitoring capabilities. This not only affects the extension of the service life of the power generation vehicle, but also fails to ensure the safe and stable operation of the power grid and avoid accidents.

[0008] Existing power generation vehicle monitoring systems often lack real-time and accurate positioning functions. Operation and maintenance personnel cannot obtain the geographic location information of the power generation vehicle in real time, which makes it difficult to quickly locate and dispatch the power generation vehicle in an emergency, affecting the speed and efficiency of emergency response.

[0009] During the use of the power generation vehicle, its parameters sometimes need to be adjusted remotely to adapt to different working environments and needs. However, existing monitoring systems usually do not support remote adjustment functions, and operation and maintenance personnel must go to the site to perform manual settings, which increases operation and maintenance costs and time costs.

[0049] 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 specification drawings. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of them. 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.

[0050] Example 1, reference Figure 1 , is an embodiment of the present invention, and provides a real-time information monitoring method for emergency power supply vehicles based on scheduling monitoring, comprising:

[0051] S1: Collect the location information of the emergency power supply vehicle.

[0052] Actively obtain the latitude, longitude and speed information of the emergency power supply vehicle through the GPS receiver.

[0053] Furthermore, by obtaining the location information of the emergency power supply vehicle in real time, the monitoring center can quickly respond to power grid emergencies and dispatch the nearest emergency power supply vehicle to provide support, thereby greatly shortening the accident response time. Accurate location information allows the monitoring center to allocate resources more effectively, ensuring that each emergency power supply vehicle is deployed where it is most needed, and improving the overall power grid operation efficiency.

[0054] It should be noted that when the emergency power supply vehicle moves quickly on the highway to respond to emergency needs, the GPS receiver will automatically increase the frequency of data collection to ensure that the monitoring center can track the precise location of the vehicle in real time. When the vehicle reaches its destination and is stationary, the receiver will reduce the frequency of data collection to reduce unnecessary data transmission and improve monitoring efficiency.

[0055] S2: Send the location information to the remote monitoring center via the wireless communication network.

[0056] Use mobile network base stations to assist in positioning; transmit location information to the remote monitoring center in real time via the 4G network.

[0057] Detect the availability of GPS signals;

[0058] When it is detected that GPS is unavailable, the mobile network base station is started to assist in positioning;

[0059] Calculate the location of the emergency power supply vehicle by analyzing the signal characteristics from multiple mobile network base stations;

[0060] Combine the auxiliary positioning results with the GPS positioning results.

[0061] Furthermore, the 4G network is selected as the main wireless communication means because it has a high data transmission rate and a wide coverage range, which is suitable for the mobile environment of the emergency power supply vehicle. In addition, the network switching logic is considered in the system design, which can automatically switch to other available wireless communication networks, such as 3G or 5G networks, when the 4G network is unavailable, to ensure the continuous transmission of location information.

[0062] It should be noted that, considering that the GPS signal may be interfered by urban buildings or terrain, the present invention also includes a signal strength detection mechanism. When the GPS signal is weak or unavailable, the system will automatically switch to auxiliary positioning mode and use the mobile network base station for positioning. For example, in the center of a city with tall buildings, the GPS signal may be blocked. At this time, the monitoring system of the emergency power supply vehicle will detect the decrease in GPS signal strength and automatically start the mobile network base station auxiliary positioning to ensure the continuity and accuracy of the vehicle location information.

[0063] It should also be noted that when the GPS signal is unavailable, the present invention uses mobile network base station assisted positioning, and uses a positioning algorithm to calculate the approximate location of the emergency power supply vehicle by analyzing the signal characteristics (such as signal strength, time difference, etc.) from multiple base stations. When the emergency power supply vehicle enters an underground facility or tunnel, the GPS signal may be completely lost. At this time, the system will automatically start the mobile network base station assisted positioning, estimate the vehicle location by analyzing the base station signal characteristics, and ensure that the monitoring center can continuously track the vehicle location.

[0064] Calculate the position of the emergency power supply vehicle relative to the base station by analyzing the signal availability, arrival time difference and signal arrival angle from multiple mobile network base stations;

[0065] The location information from multiple base stations is processed by triangulation or weighted averaging;

[0066] The calculated position is integrated with the real-time GPS data to optimize the positioning result and generate the final position information.

[0067] Furthermore, by analyzing the signal availability, time difference of arrival (TDOA) and signal angle of arrival (AOA) from multiple mobile network base stations, the position of the emergency power supply vehicle relative to the base station is calculated. The rationality of this method lies in that it integrates multiple data sources to improve the accuracy and reliability of positioning. Signal availability helps to determine the stability of the current base station signal, while the time difference of arrival and the angle of arrival of the signal provide the key spatiotemporal information required for positioning.

[0068] It should be noted that the accuracy of positioning can be improved by using triangulation or weighted averaging to comprehensively process the location information from multiple base stations. Triangulation determines the location of an object by calculating the arrival time difference, while the weighted average method takes into account the signal-to-noise ratio of the signals from different base stations, giving greater weight to base stations with higher signal quality. For example, in an emergency response, the emergency power supply vehicle is located within the coverage area of ​​multiple base stations. Through triangulation, the system can determine that the vehicle is in a smaller area. Then, through the weighted average method, the system can calculate a more accurate location based on the strength and quality of the signals from each base station, thereby improving the positioning accuracy of the vehicle.

[0069] It should also be noted that the calculated position is fused with real-time GPS data to optimize the positioning results and generate the final position information. The innovation of this step is that it not only improves the accuracy of positioning, but also enhances the system's adaptability to environmental changes. When the GPS signal is strong, the system relies on GPS data; when the GPS signal is weak, the system relies on base station auxiliary positioning data. For example, when the emergency power supply vehicle enters a tunnel or underground facility from outdoors, the GPS signal may suddenly disappear. At this time, the system will automatically switch to base station assisted positioning and smoothly transition through the data fusion algorithm to ensure the continuity of the vehicle's position information. When the vehicle returns to the outdoors and the GPS signal is restored, the system automatically switches back to GPS positioning again to ensure the accuracy of the positioning results.

[0070] S3: Real-time monitoring and command and dispatch based on location information.

[0071] When it is necessary to replace a generator car with a different baud rate, adjust the baud rate of the emergency power supply car and the monitoring system device through the remote monitoring center to ensure that the baud rate is consistent with that of the generator car and the monitoring center;

[0072] According to the real-time location information of the emergency power supply vehicle, its current location, movement trajectory and operating status are displayed on the graphical interface of the monitoring center;

[0073] Compare the location information with the scheduled dispatch plan to determine whether the emergency power supply vehicle is in the scheduled working area;

[0074] When the emergency power supply vehicle is detected to deviate from the predetermined track or abnormally stagnates, an alarm signal is issued, and instructions are sent remotely through the dispatch center to adjust the route of the emergency power supply vehicle;

[0075] Based on real-time location information, the dispatch center automatically generates the optimal dispatch path and dynamically adjusts the task allocation of emergency power supply vehicles.

[0076] Furthermore, when it is necessary to replace a generator car with a different baud rate, the baud rate of the emergency power supply car and the monitoring system device is automatically adjusted through the remote monitoring center. The rationality of this step is that different devices may use different communication baud rates, and the automatic adjustment ensures seamless communication without the intervention of on-site technicians. This automatic adjustment reduces the risk of communication failure due to mismatched communication parameters and improves the reliability of communication, thereby ensuring the continuity and stability of command and dispatch.

[0077] Furthermore, the current location, movement trajectory and operating status of the emergency power supply vehicle are displayed on the graphical interface of the monitoring center. The rationality of this step is that the visual information can help operators quickly understand the real-time status of the vehicle and make more accurate decisions. Through the graphical interface, monitoring personnel can intuitively monitor the vehicle status, improve the efficiency and response speed of monitoring, and help to make quick decisions in emergency situations.

[0078] It should be noted that when the emergency power supply vehicle is detected to deviate from the predetermined trajectory or abnormal stagnation, the system will issue an alarm signal and send instructions remotely through the dispatch center. The rationality of this step lies in that it can identify and respond to potential problems in a timely manner, reducing the risk of accidents or delays. The rapid response mechanism improves the ability to handle emergencies, helps maintain the stable operation of the power grid, and reduces losses caused by untimely emergency response.

[0079] It should also be noted that based on real-time location information, the dispatch center automatically generates the optimal dispatch path and dynamically adjusts the task allocation of the emergency power supply vehicle. The rationality of this step lies in that it can optimize resource allocation according to real-time conditions and improve the efficiency of emergency response. Dynamic dispatch path optimization enables the emergency power supply vehicle to quickly adjust tasks according to actual needs, improve resource utilization efficiency, and reduce unnecessary travel and time waste.

[0095] Example 5 is an embodiment of the present invention, which provides a real-time information monitoring method for emergency power supply vehicles based on scheduling and monitoring. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through economic benefit calculation and simulation experiments.

[0096] In order to verify the effectiveness of the real-time information monitoring method of the emergency power supply vehicle based on dispatch monitoring proposed in the present invention, this experiment conducted a comparative test on two groups of emergency power supply vehicles with different configurations in an actual environment: one group used a traditional monitoring system, and the other group used the multi-sensor fusion monitoring system of the present invention. The test environment includes complex terrain in the city (high-rise dense areas) and open terrain in the suburbs, with the purpose of simulating the actual operating conditions of the emergency power supply vehicle in different environments.

[0097] The following equipment were installed in the experiment:

[0098] GPS receiver: used to collect vehicle's latitude, longitude and speed data.

[0099] 4G communication module: used to transmit location information to the remote monitoring center in real time via the 4G network.

[0100] Mobile base station assisted positioning system: automatically starts when GPS signal is unavailable to assist in calculating location information.

[0101] D5000 monitoring system: used in the remote monitoring center to receive, process, and display real-time location information and trajectories, and to conduct command and dispatch through a graphical interface.

[0102] There are two experimental vehicles in total. Each vehicle drove for 2 hours in different terrains to monitor key parameters such as positioning accuracy, data transmission stability, and the number of auxiliary positioning starts under strong and weak GPS signals. The experiment also monitored the response time and dispatch accuracy of the monitoring center based on the real-time data of the emergency power supply vehicle, and focused on comparing the actual application of the baud rate automatic adjustment function. The experimental data is shown in Table 1.

[0103] Table 1 Experimental data comparison table

[0104]

[0105]

[0106] It can be clearly seen from the experimental data that the emergency power supply vehicle monitoring system of the present invention shows obvious advantages in multiple core indicators, especially in positioning accuracy and transmission stability in complex environments, demonstrating its innovativeness.

[0107] First, in terms of the success rate of position data transmission, the system of the present invention achieved 98% and 97% on both test vehicles, which shows that the multi-sensor fusion technology of the present invention ensures stable data transmission in the changing urban and open environments. The success rate of the traditional system is only 77% and 74%, indicating that it performs poorly under conditions of poor signal or complex terrain. This difference is due to the fact that the present invention promptly activates the base station auxiliary positioning function when the GPS signal is weak or unavailable, so that effective position information can still be obtained and transmitted in an environment with extremely poor signal.

[0108] Secondly, in terms of average positioning error, the system of the present invention controls the error between 2.4 meters and 2.6 meters by combining base station auxiliary positioning and fusion processing of GPS data, while the error of the traditional system is as high as 3.8 meters and 4 meters. In complex urban terrain, traditional systems often rely on a single GPS signal, and in areas with tall buildings, the signal attenuation is serious, resulting in increased errors. The present invention fuses base station and GPS data through weighted averaging method, effectively reducing positioning errors.

[0109] In addition, the experiment also shows that the system of the present invention is more accurate in dispatching in emergency situations. During the experiment, the number of trajectory deviation alarms of the system of the present invention was significantly less than that of the traditional system (1 time vs. 5 times). This means that the system of the present invention can monitor the actual driving route of the vehicle more accurately and issue an alarm earlier when the vehicle deviates from the predetermined trajectory, helping to make timely dispatch and adjustments.

[0110] Another significant advantage of the system of the present invention is the number of times base station assisted positioning is started. When GPS signals are unavailable, the traditional system frequently relies on base station assisted positioning (up to 15 and 12 times), while the system of the present invention, due to its fusion of multi-sensor data, only starts 7 and 6 times, significantly reducing the start frequency of assisted positioning. This not only improves the reliability of the system, but also reduces the energy consumption of the equipment.

[0111] Finally, data transmission delay also demonstrates the significant advantages of the system of the present invention. Through optimized data compression and transmission strategies, the present invention controls data delay within 0.8 seconds, while the delay of the traditional system is 1.7 seconds and 2.1 seconds. This difference is particularly critical in emergency dispatch scenarios and can significantly improve the response speed of dispatch instructions.

[0112] It should be noted that in this experiment, the traditional technology used is mainly an emergency power supply vehicle monitoring system based on a single GPS signal. The system relies on the on-board GPS receiver to obtain the location information of the emergency power supply vehicle and transmits the information to the remote monitoring center through the 4G communication module. Specifically, the positioning principle of the traditional system is as follows: the location information of the emergency power supply vehicle is completely dependent on the satellite data obtained by the GPS receiver. The GPS receiver calculates the latitude and longitude, speed and other information of the vehicle based on the signals received from multiple satellites. When the signal is strong, this positioning method can provide relatively accurate location data.

[0113] The traditional system transmits the location information collected by GPS to the remote monitoring center in real time through the 4G network. After receiving the data, the monitoring center analyzes it and displays the vehicle's current location, driving trajectory and other information in the system. The traditional technology system does not have the ability of multi-sensor fusion, and it only relies on GPS signals. If the GPS signal is lost or weakened (for example, in a high-rise building area or underground tunnel), the system will not be able to accurately obtain the real-time location information of the vehicle. This will lead to the loss of vehicle location, increased errors, and even the inability to monitor in real time.

[0114] Traditional systems do not have a backup positioning solution when GPS signals are unavailable. Therefore, when the emergency power supply vehicle enters a GPS blind spot or the signal is blocked, the system will not be able to effectively monitor or provide position corrections. In addition, traditional systems do not have an automatic baud rate adjustment function, and manual adjustments are required when switching between different power generation vehicles and monitoring centers, increasing the cost and difficulty of on-site maintenance.

[0115] In summary, the experimental data fully proves that the real-time information monitoring system based on dispatching and monitoring emergency power supply vehicles of the present invention has excellent stability and accuracy in complex environments, especially under conditions where the GPS signal is unstable. By introducing base station assisted positioning and multi-sensor data fusion, the present invention not only improves the success rate of location information transmission, but also reduces positioning errors, thereby enhancing the timeliness and accuracy of dispatching and commanding.

[0116] 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.
