DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0018] A management system for calculating shallow areas of waterway dredging and issuing intelligent work orders, such as Figure 1 As shown, it includes a data processing module 1, which is used to collect measurement data and shallow area dredging data obtained based on analysis of the measurement data; a dredging operation scheduling module 2, which is connected to the data processing module 1. The dredging operation scheduling module 2 is also connected to an external data source to receive dredging operation data. The dredging operation scheduling module 2 is used to divide the waterway in a grid form, identify shallow points in the waterway based on the grid, and determine the shallow area and the permitted construction area through the shallow points, and deploy ships in combination with the dredging operation data; a work order dispatching module 3, which is connected to the dredging operation scheduling module 2, and is used to screen and recommend construction ships according to the status information of the ship, select the ship type according to the dredging volume in the shallow area, and generate a work order.

[0019] Specifically, the present invention can automate calculation, intelligent scheduling and real-time monitoring, optimize dredging operation plans and work order distribution, improve operation efficiency, reduce resource waste, and reduce manual intervention. The management system for shallow area calculation and intelligent work order distribution of waterway dredging is based on big data and intelligent algorithms, providing scientific support for dredging operations in shallow areas and promoting the modernization and intelligence of waterway dredging management.

[0020] The data processing module 1 can accurately calculate the change in water depth in shallow areas, reasonably predict the dredging needs, and avoid over-dredging or under-dredging.

[0021] The data processing module 1 supports a variety of construction data types and analyzes data in different formats, including high-frequency water depth data, low-frequency water depth data, and minimum water depth data.

[0022] The dredging operation scheduling module 2 automatically generates shallow areas based on the shallow area hydrological data in the real-time dredging operation data, and realizes the visualization management of shallow areas in combination with the visualization module 4. Combining real-time data and intelligent algorithms, the time management and resource scheduling of dredging operations are optimized, the construction scheduling time is reduced, the construction cost is reduced, and the overall work efficiency is improved.

[0023] The work order dispatching module 3 automatically generates and dispatches work orders according to the shallow area dredging requirements and operation plan to ensure the timely execution of dredging tasks.

[0024] In complex and dynamic shallow dredging operations, the present invention uses technologies such as intelligent calculation, automatic scheduling, and real-time monitoring to accurately calculate dredging needs, optimize resource allocation, automatically assign work tasks, and ensure the efficiency and accuracy of the operation process. By solving the above technical problems, the system greatly improves the efficiency and accuracy of waterway dredging operations, reduces costs, and promotes the development of waterway dredging management towards intelligence and automation.

[0025] In a preferred embodiment, the dredging operation scheduling module 2 includes a grid division unit 21, which is used to divide the waterway into a number of regular grids according to the terrain data of the waterway, and correspond the dredging operation data to the grids; a shallow area calculation unit 22, connected to the grid division unit 21, is used to obtain the water depth value according to the shallow area hydrological data, determine the area where the water depth value is lower than a preset value as a shallow point, associate the shallow point with the corresponding mileage pile and the corresponding grid, and determine the scope of the shallow area and the permitted construction area; a ship deployment unit 23, connected to the shallow area calculation unit 22, is used to calculate the dredging time and number of ships required for each shallow area according to the dredging volume of the shallow area and the construction capacity of the ship, and deploy ships based on the dredging operation data; the dredging operation data includes shallow area hydrological data, ship dynamic data and operation progress.

[0026] In a preferred embodiment, the shallow area is formed by connecting the grids where the shallow points in the measurement data are located, allowing the construction area to be extended by a first length in the upstream and downstream directions and by a second length in the first side slope and second side slope directions based on the shallow area.

[0027] Specifically, the dredging operation scheduling module 2 can intelligently schedule ships and optimize the operation sequence and resource allocation according to real-time shallow area hydrological data, ship dynamic data and operation progress.

[0028] The dredging operation scheduling module 2 provides an intelligent scheduling algorithm, which combines with the work order dispatching module 3 and the data processing module 1 to automatically dispatch work orders according to real-time collected data, thereby improving the utilization of ships and the balanced allocation of resources.

[0029] In a specific embodiment, the specific calculation rules of the present invention are as follows: a longitudinal construction mileage pile is set every 100 meters from upstream to downstream of the current waterway as the construction boundary of the shallow area, and a waterway construction strip is divided every 60 meters from the north line to the south line (the deep-water channel is taken as an example in the report) to assist in construction.

[0030] The management system for calculating shallow areas of dredging and issuing intelligent work orders adopts a grid format based on the current channel construction and management, dividing the 360m channel into individual small grids of 100*20m. It seeks for patterns in complex measurement data with uneven positions and incompletely unified survey line directions, and unifies irregularly located shallow points through the shallow point-milepost-grid classification method. On the premise of meeting the requirements of channel construction, it uses the grid to find shallow points, determines the milepost through the shallow points, and determines the construction boundary. It supports automatic calculation of uploaded measurement depth data to generate shallow areas.

[0031] The shallow area calculation distinguishes between the shallow area and the permitted construction area. The shallow area is formed by connecting the grids where the shallow points in the measurement data are located. It is the area where the construction ship actually needs to construct. However, for actual construction considerations, the ship itself is about 200 meters long and 30 meters wide, and it is necessary to turn around in the shallow area. Therefore, a buffer zone is added on the basis of the shallow area. The design rule of the buffer zone is to extend the first length upstream and downstream respectively, which is 200 meters in this embodiment, and to extend the second length in the direction of the first side slope and the second side slope respectively, which is 60 meters in this embodiment for the north and south slopes to form a permitted construction area. It should be noted that no alarm information will be generated when the ship is constructing in this area, but when issuing a work order, the construction pile number is based on the shallow area, which has nothing to do with the permitted construction area.

[0032] The shallow area calculation unit 22 only calculates the shallow area. After the shallow area is determined, the dredging operation scheduling module 2 automatically forms the permitted construction area according to the rules and displays it in the work order, which is more in line with the actual construction process. It changes the previous workflow of manually drawing lines to confirm the shallow construction area, accurately identifies each shallow point in the data, and realizes one-click drawing.

[0033] Since ship production scheduling and mapping calculation and analysis is a continuous process, as the core link of ship production scheduling dredging operations, ship production scheduling needs to comprehensively consider the ship's construction qualifications, construction capabilities and current construction status. Dredging operation scheduling module 2 screens out ships that meet construction requirements by judging a series of conditions such as whether the ship has completed the entry construction procedures, whether it meets the access standards, and whether it holds the corresponding certificates.

[0034] On this basis, combined with the volume of shallow areas, the dredging operation scheduling module 2 intelligently deploys ships with different construction capabilities to ensure the rational use of resources; at the same time, based on the average water depth of each construction strip in the waterway, the key construction strips are accurately identified, thereby building a complete and standard shallow area-work order-scheduling order workflow.

[0035] In this process, a work order is formed by determining the corresponding construction ship in a single shallow area, and then a dispatch order is generated by summarizing multiple work orders, which are finally distributed to all ships to achieve efficient collaborative operations.

[0036] In a preferred embodiment, the dredging operation scheduling module 2 also includes a construction frame allocation unit 26, which is used to allocate construction resources, including covering all strips in the shallow area of ​​the waterway; giving priority or additional allocation of construction resources to shallow areas with shallow point values ​​lower than the preset water depth; and cross-allocating construction resources for the inlet channel and the outlet channel.

[0037] Specifically, the present invention changes the problem that in the traditional mode, work orders are manually written and distributed, which is inefficient and prone to errors and cannot be flexibly adjusted according to real-time conditions.

[0038] The present invention automatically generates work orders through big data analysis and intelligent computing, ensuring that the work tasks are delivered to the construction unit in a timely and accurate manner. At the same time, the system of the present invention automatically adjusts the priority of the work orders to ensure that the most urgent and most intervention-requiring tasks are processed first.

[0039] Specifically, after the shallow area calculation is completed, the water depth, earthwork volume, average water depth of the strip, etc. of each shallow area will be automatically calculated. The system uses a series of algorithms to determine the current construction ships and the required construction volume. It gives multiple optional ship deployment work orders through key construction, priority scheduling and other conditions, and then the user determines the appropriate work order based on the actual construction situation. The main methods are as follows: Ship selection: First, find the ship that meets the construction conditions based on the ship's access status, and then select the ship that has completed the entry procedures and can be constructed based on the ship's entry and exit status. At the same time, it is necessary to determine whether all the ship's certificates are within the qualified period. Only ships that meet all conditions will be designated as recommended construction ships in the work order; Ship scheduling: Select the appropriate ship based on the shallow area volume, and determine the large, medium and small types of ships through the basic ship data.

[0040] The earthwork volume calculation method of the present invention is to calculate the earthwork volume of the shallow area based on the determined shallow area range and water depth data in combination with the geographic information system (GIS) technology, and regard the shallow area as composed of multiple three-dimensional units. The earthwork volume of the shallow area is obtained by accumulating the volumes of the units.

[0041] The present invention collects the status information of the ship, including the admission status, entry and exit status, certificate validity period of the ship, and also collects the construction capability of the ship.

[0042] According to the access status of the ship, determine whether the ship meets the basic conditions for participating in the construction; through the entry and exit status, determine whether the ship can currently participate in the construction; check the validity period of the certificate to ensure that the ship's operation is legal and compliant. Only ships that meet the above conditions are identified as ships that can be constructed and are screened and recommended; the allocation principles of key construction diagrams are: 1. All strips in the shallow area need to be fully covered. In this embodiment, a total of 6 strips from the north line to the south line are taken as an example, and the construction resources need to fully cover the 6 strips; 2. Multiple coverage with low shallow point values, that is, areas with low average water depth in the strip need priority or additional allocation of construction resources; 3. When allocating the block diagram, the inlet and outlet channels need to be cross-allocated. Taking 6 strips as an example, assuming that 1, 2, and 3 are inlet channels and 4, 5, and 6 are outlet channels, then 14 or 16 cross-allocations are required. Construction resources cannot be allocated continuously in 123.

[0043] During construction, there may be random boats or mud pulling, which does not need to be considered in the present invention.

[0044] In a preferred embodiment, the dredging operation scheduling module 2 further includes a shallow area data editing unit 24 for controllably merging adjacent shallow areas.

[0045] Specifically, the shallow area list of the shallow area data editing unit 24 can be operated to locate the corresponding shallow area, and multiple shallow areas can be selected to merge the shallow areas. The present invention currently does not support the splitting of shallow areas.

[0046] The shallow area data editing unit 24 supports users to modify the shallow area generated by the system. Click Edit to enter the modification mode, allowing multiple accounts to modify and save data. Modify and select the shallow area to be published, and click to publish, but only some accounts have the authority to publish.

[0047] And the shallow area data editing unit 24 only supports the merging of adjacent shallow areas. When merging non-adjacent shallow areas, a pop-up window prompt is required. When merging shallow areas or publishing shallow areas, an irreversible pop-up window prompt is required, and the user is required to determine to proceed to the next step.

[0048] In a preferred embodiment, a visualization module is also included, which is connected to the data processing module 1 and is used to display the shallow area dredging data in a visualized form. The shallow area dredging data includes sediment thickness distribution and dynamic changes in siltation; the measurement data includes high-frequency water depth data, low-frequency water depth data, and minimum water depth data.

[0049] Specifically, the measurement data are displayed in the form of heat maps, three-dimensional topographic maps, etc. The visualization module 4 of the present invention innovatively combines geographic information technology (GIS) to visualize data such as sediment thickness distribution and dynamic changes in siltation, and intuitively displays the dredging needs in shallow areas.

[0050] The visualization results are displayed superimposed with historical data to facilitate comparative analysis and assist in the optimization of dredging strategies.

[0051] In a preferred embodiment, it also includes a monitoring and alarm module 5, which is connected to the work order distribution module 3. The monitoring and alarm module 5 includes a plurality of monitoring sensors installed on the ship. The ship operation status data is collected through the monitoring sensors. The monitoring and alarm module 5 is used to compare the ship operation status data with the operation process of the work order, and output an alarm signal based on the comparison result.

[0052] Specifically, the monitoring and alarm module 5 monitors the progress of the dredging operation and the status of the ship in real time, and issues early warnings for abnormal situations in a timely manner to ensure smooth progress of the operation.

[0053] Specifically, the monitoring and alarm module 5 combines IoT devices and sensors to monitor the ship's operating status, equipment operation, and dredging changes in real time, and transmits data to the shore-side cloud platform. The system uses real-time feedback and abnormal warning functions to ensure that problems are discovered and solved in a timely manner. The project summarizes years of on-site construction and management experience, and has formulated six major categories and twelve subcategories of alarm rules for ship construction, mud dumping, and supervision. The system automatically judges through the collected construction data, documents, and other content, and binds them to each ship.

[0054] The alarm rules are shown in Table 1.

[0055] Table 1 The alarm types in Table 1 include construction alarm, which is triggered when the ship is working outside the shallow area to ensure that the construction activities are carried out within the specified shallow area; overload alarm, including rake overload alarm and pre-mud dumping overload alarm. Rake overload alarm refers to the triggering of overload during rake operation; pre-mud dumping overload alarm is to check whether the ship is overloaded before dumping, and issue an alarm if overloaded.

[0056] Illegal mud dumping alarms include mud dumping outside the permitted mud dumping area, repeated mud dumping location alarms, and dumping area overuse alarms. The mud dumping outside the permitted mud dumping area alarm is used to monitor whether the ship is dumping mud outside the specified mud dumping area; the repeated mud dumping location alarm is used to prevent the ship from dumping mud multiple times at the same location, causing local siltation; and the dumping area overuse alarm is used to prevent the dumping area from being overused.

[0057] Illegal screenshot alarms, including screenshots that do not meet mud dumping requirements, screenshot water density inconsistency, screenshot soil density inconsistency, and screenshot time before mud dumping greater than 60s alarm, are used to monitor the screenshot situation during the mud dumping operation to ensure that the screenshot data meets the preset requirements; loading time alarm: This alarm is triggered when the loading time is insufficient to ensure that the ship's loading operation meets the specified time requirements; digging distance alarm: If the digging distance is insufficient, this alarm is triggered to ensure the effective distance of the dredging operation and ensure the dredging effect.

[0058] In a preferred embodiment, the dredging operation scheduling module 2 also includes a data preview unit 25, which stores and displays shallow area data and mapping analysis data, the shallow area data includes information about the shallow area, and the mapping analysis data includes mapping analysis data corresponding to the measurement data.

[0059] Specifically, the data preview unit 25 and the shallow area data editing unit 24 of the present invention provide real-time preview and editing functions, and the user can dynamically adjust the display content according to needs.

[0060] In a preferred embodiment, the data processing module 1 collects measurement data each time to form a corresponding map. The collected measurement data includes assessment measurement of data covering the entire waterway and adjustment measurement of data in the shallow area of ​​the previous map. The work order distribution module 3 references the work order corresponding to the previous map as the work order formed under the adjustment measurement.

[0061] Specifically, the measurement process of the present invention is to do assessment measurement at the beginning and end of each month, interspersed with construction section adjustment measurement in between, the assessment measurement covers the entire waterway, and the adjustment measurement only measures the area with shallow points in the previous survey map (including assessment survey map or adjustment survey map). There will be a large shallow area in the assessment measurement at the beginning of the month. As the dredging construction proceeds, the shallow area will become smaller and smaller, but the shallow area range in two consecutive survey maps will not be adjusted much. Therefore, the survey map for adjustment measurement does not need to recalculate the shallow area, but only needs to reference the shallow area of ​​the previous survey map, support users to adjust the shallow area range, and on this basis, reference the work order of the previous survey map and adjust it.

[0062] A management method for calculating shallow areas of waterway dredging and intelligent work order distribution is applied to a management system for calculating shallow areas of waterway dredging and intelligent work order distribution, such as Figure 2 As shown, it includes step S1, the data processing module 1 collects the measurement data and the shallow area dredging data obtained based on the analysis of the measurement data; step S2, the dredging operation scheduling module 2 receives the dredging operation data, divides the waterway in the form of a grid, identifies the shallow points in the waterway based on the grid, and determines the shallow area and the permitted construction area through the shallow points, and deploys the ship in combination with the dredging operation data; step S3, the work order dispatching module 3 screens and recommends the construction ship according to the status information of the ship, selects the ship type according to the dredging volume in the shallow area, and generates a work order.

[0063] In a specific embodiment, the complete process of the present invention includes the following steps, and the specific implementation includes the following steps: Step 1: Data collection and preprocessing: upload the measurement data through the sensor or data interface, and perform data format conversion and cleaning. After successful uploading, the data will be automatically numbered.

[0064] Step 2: Preview the measurement data. After the data is imported into the system, the data can be previewed according to the user's permissions.

[0065] Step 3, shallow area calculation, after data confirmation and automatic calculation, enter the shallow area calculation unit 22. The data list for shallow area calculation and analysis only contains data used to generate shallow area frame diagrams, i.e., high-frequency water depths for initial assessment, supplementary assessment, and assessment of passed measurements, minimum water depth data for full construction and encrypted construction. When adjusting the measured map, there is no need to recalculate the shallow area, but only need to reference the shallow area of ​​the previous map.

[0066] Step 4, shallow area data preview, by viewing the section and mileage post names and light buoy information on the map, click on a shallow area data to view the shallow area information generated by the system, and the map will be positioned to the location of the currently selected shallow area. Click Calculate to view the mapping analysis data of the entire map.

[0067] Step 5, shallow area data editing: click on the shallow area list on the left to locate the corresponding shallow area, select multiple shallow areas to merge shallow areas, and currently do not support shallow area splitting. Support users to modify the shallow areas generated by the system. Click Edit to enter the modification mode. Allow multiple accounts to modify and save data. Modify and select the shallow area to be published. Click to publish, but only some accounts have the permission to publish. Only adjacent shallow areas are supported to be merged. A pop-up window prompt is required when merging non-adjacent shallow areas. A pop-up window prompt that cannot be returned is required when merging shallow areas or publishing shallow areas. It is up to the user to determine to proceed to the next step.

[0068] Step 6, measurement data calculation, click calculate to view the mapping analysis content related to this mapping, including the number of sections that do not meet the 12.5-meter water depth requirement, the number of shallow points that do not meet the 12.5-meter water depth requirement; the shallow area that does not meet the 12.5-meter water depth requirement; the difference between high and low frequency volumes; the amount of shallow engineering required for this mapping; the average water depth in the north of the trough; the average water depth in the middle of the trough; the average water depth in the south of the trough; the overall average water depth of the waterway; the average water depth 325 meters outside the north line; the average water depth 325 meters outside the south line; the published and unpublished shallow areas in the same mapping are distinguished by different colors. Click the published shallow area to view the earthwork volume and generate an intelligent work order.

[0069] Step 7, smart work order, divides the shallow area according to the measured map, supports users to adjust the scope of the shallow area, and generates smart work orders through adjustment.

[0070] Step 8, ship dispatch management, users can select and operate construction adjustment orders through smart work orders. When creating a construction adjustment order, one or more work orders can be selected and the ship can be intelligently and evenly distributed according to the selected work orders. While recommending them to users, manual adjustments are also supported.

[0071] Step 9, construction adjustment order approval. After the construction adjustment order is successfully created, a process approval document will be generated, which includes the effective time of the construction adjustment order and the sequence of the ship's mud dumping time, binds the ship number and the adjustment order management, and provides functions such as ship construction alarm and volume calculation. The process supports cancellation, rejection and other operations. At the same time, the construction adjustment order also supports re-modification and retains the rejection record.

[0072] Step 10, abnormal alarm for ship construction: After the construction adjustment form is approved, the supervision unit will dispatch the work of the relevant ships according to the construction section and ship recommendation of the adjustment form. At the same time, the AIS data of the ship will be transmitted back in real time, and the dredging operation will be carried out according to the time and location specified in the adjustment form. If the operation is not carried out according to the specified time and location, an abnormal alarm will be issued to the relevant units on the shore and ship.

[0073] In a specific embodiment, the complete dredging operation process of the present invention is as follows: Figure 3 As shown in the figure, the process starts with surveying, and monthly mapping is carried out to generate high-frequency data y and low-frequency data d, which are stored in the system. Then, the shallow construction area is generated based on the survey data, and then the construction section adjustment list is generated, which specifies the effective time of the adjustment list and the operating ship, and the ship starts construction.

[0074] Monitor the difference between high and low frequency water depths and generate measurement reports.

[0075] The screenshot data of the supervision is stored in the form of Excel tables and pictures. The minimum earthwork volume difference in the Excel table is used as the construction volume of the ship and stored in the ship record. At the same time, the mud dumping time is recorded to determine whether the ship is in the mud dumping area. If it is, the mud dumping area location is recorded and the mud dumping volume is counted. If it is not, the illegal mud dumping alarm is triggered. It will also decide whether to record the adjusted single ship record or the latest adjusted single ship record based on the relationship between the mud dumping time and the effective time of the adjustment order.

[0076] During the construction process, the supervisor screenshots the data and the real-time construction recorder to record the mud throwing time, the start and end of the rake status, etc. It is determined whether the end of the rake time is later than the start of the rake time. If it is later, it is in the end of the rake state, otherwise it is in the start of the rake state.

[0077] Determine whether the average draft of the ship is less than the full-load draft. If it is less, the overload alarm is triggered and recorded, otherwise it is recorded as normal load. At the same time, determine whether the ship is in the shallow construction area. If not, the construction alarm outside the operation area is triggered and recorded.

[0078] Calculate the digging distance (raking start time - raking track length of lowering time) to obtain the horizontal strip distribution percentage and the longitudinal cell / segment distribution percentage. Then, based on the relationship between the mud dumping time and the effective time of the adjustment order, determine whether it is the current ship or the next ship, and record the ship volume of each strip (divided into different strip areas from north to south) and each cell / segment.

[0079] In this embodiment, the Yangtze River Estuary waterway construction section is used as the background. Figure 4 As shown, the measurement data can be manually imported into the system by the user. When importing, the data measurement date, measurement channel, measurement type and type of uploaded data must be specified. Only one piece of measurement data is allowed to be uploaded at a time.

[0080] like Figure 5 As shown, the data number is automatically generated after the data is uploaded, and the data under a group can be operated to confirm the data ( Figure 5 Click the circle on the right to confirm the data). After all the data are confirmed, the data status is considered confirmed and cannot be modified after confirmation.

[0081] like Figure 6 As shown in the figure, after importing the data into the system, all users can preview the data. Clicking the data to view the corresponding data details, only some users can confirm the data. The strip line is not displayed when previewing the data.

[0082] like Figure 7 As shown, the section and mileage post names and light buoy information can be viewed on the map. Click a shallow area data to view the shallow area information generated by the system. At the same time, the map is positioned to the location of the currently selected shallow area.

[0083] like Figure 8 As shown in the figure, the published and unpublished shallow areas in the same survey map are distinguished by different colors. Click the published shallow area to view the earthwork volume and generate an intelligent work order.

[0084] like Fig. 9 As shown, the work order generation rule in this embodiment is that when arranging ships, the shallow area in the middle section of the channel is given priority, and 9-10 ships or 12-13 ships are arranged in the whole section according to the amount of earthwork. The method is: the whole section is about 20 kilometers long, which is generally divided into 3-4 shallow areas, and 3-4 ships are allocated to each shallow area.

[0085] like Fig.10 As shown, ship dispatch includes two parts: intelligent work order and construction section adjustment order. The intelligent work order is the work order saved from the work order distribution module 3. Click the data list on the left to view all the work orders corresponding to a certain survey.

[0086] like Fig.11As shown, after clicking Approve, a multiple-selection box and operation button will appear in the form. After selecting the work order for which an adjustment order needs to be created, click Create Construction Adjustment Order below to fill in the name, effective time, remarks and other information of the construction adjustment order. A construction adjustment order formed by multiple selected work orders will be generated. After previewing and confirming that there are no errors, the construction adjustment order approval phase will be entered. At the same time, the selected work order will be deleted from the smart work order module.

[0087] After the construction adjustment order is approved, the system of the present invention binds the relationship between the ship number and the adjustment order according to the sequence of the effective time of the construction adjustment order and the ship's mud dumping time, thereby providing functions such as ship construction alarm and volume calculation.

[0088] If the approval of the construction adjustment order is rejected, the rejected work order will re-enter the work order distribution module 3. The construction adjustment order module will retain the rejected content and will not allow modification.

[0089] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
