Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system configurations, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
A water supply network is a set of systems for providing potable and industrial water to cities, villages or buildings, typically consisting of a series of pipes and facilities intended to transport a source of water from a source of water (such as a reservoir, river, well, etc.) to a source of water, such as a residential home, construction site or market.
In the transportation process of the water supply network, the water leakage phenomenon of the water supply network is caused by the occurrence of problems of pipelines or equipment. However, water leakage not only wastes water resources, but also can cause problems such as economic loss, water supply interruption, damage to infrastructure, water quality reduction and the like, so that leakage monitoring of a water supply network is very necessary.
In the related art, the leakage monitoring method of the water supply network has the problems of low efficiency and high cost, and is difficult to deal with the cells under special conditions.
In order to solve the problem, the application provides a leakage monitoring method of a water supply network, which can easily cope with a cell under a special condition without constructing DMA (direct memory access), and is low-cost, efficient and convenient. The control method proposed in the present application will be described below by way of specific examples.
The leakage monitoring method of the water supply network provided by the embodiment of the application can be applied to electronic devices such as mobile phones, tablet computers, vehicle-mounted devices, augmented reality (augmented reality, AR)/Virtual Reality (VR) devices, notebook computers, ultra-mobile personal computer (UMPC), netbooks, personal digital assistants (personal digital assistant, PDA) and the like, and the embodiment of the application does not limit the specific types of the electronic devices.
In order to explain the technical solutions proposed in the present application, the following describes each embodiment with an electronic device as an execution body.
Fig. 1 shows a schematic flow chart of a leakage monitoring method of a water supply network provided by the application, where the leakage monitoring method of the water supply network includes:
and 110, the electronic equipment constructs a pipe network map based on the water supply pipe network data and the preset map.
In order to improve flexibility and convenience of leakage monitoring, referring to fig. 2, the electronic device may acquire water supply network data, and combine the water supply network data with a preset map to obtain a network map as shown in fig. 2. The pipe network map can realize a space query function, namely, corresponding water supply pipe network information is determined through positioning, and leakage analysis of a relevant area is facilitated.
The preset map may include a hundred degree map, a google map, a Google map, and the like. The specific selection of which map is used as the base map of the pipe network map can be determined according to actual conditions.
And 120, the electronic equipment determines a target area to be monitored from the pipe network map.
After the pipe network map is constructed, the electronic equipment can determine the area to be monitored, namely the area to be monitored, from the pipe network map. For convenience of description, the region to be monitored may be referred to as a target region.
And 130, the electronic equipment calculates the total differential water quantity in the target area based on a plurality of target equipment in the target area so as to monitor the leakage of the target area.
The essence of the leakage monitoring is to determine the difference between the water supply amount and the water consumption so as to take relevant repairing measures in time and reduce the negative influence caused by the water leakage of the water supply network. In order to monitor leakage of the target area, the electronic equipment can firstly determine each target equipment in the target area by utilizing the space inquiry function of the pipe network map; and then calculating the total differential water quantity in the target area through each target device.
Wherein the total differential water volume can characterize the difference between the total water supply volume and the total water consumption volume in the target area; the larger the total differential water quantity is, the larger the difference between the total water supply quantity and the total water consumption in the target area is, namely the larger the water quantity leakage in the target area is; the smaller the gap, the smaller the gap between the total water supply amount and the total water consumption amount in the target area, that is, the smaller the water leakage in the target area. Therefore, after the total differential water quantity is calculated, leakage monitoring can be carried out on the target area.
In this embodiment, for flexibility and convenience of leakage monitoring, the electronic device integrates the water supply network data into a preset map, and constructs a network map; in the pipe network map, the electronic equipment can determine a target area to be monitored according to the requirement of a user, and then accurately position each target equipment in the target area by means of the space searching function of the pipe network map; based on each target device, the electronic device can determine the total differential water quantity in the target area to monitor the leakage condition of the water quantity in the target area.
In some embodiments, as can be seen from the foregoing, the water supply network comprises devices and pipes, with two adjacent devices being connected based on the pipes; the water supply network data comprises first coordinate information, first attribute information and flow information of the pipeline, second coordinate information, second attribute information and acquisition information of equipment; the water supply network data are mainly obtained from water service companies, and a coordinate system adopted by general water service companies is a WGS84 coordinate system. Therefore, the first coordinate information and the second coordinate information are both coordinate information in the WGS84 coordinate system.
Based on this, the foregoing step 110 specifically includes:
step 111, the electronic device converts the first coordinate information and the second coordinate information into a coordinate system of a preset map, and obtains the converted first coordinate information and second coordinate information.
In order to integrate the water supply network into the preset map, first, coordinate information between the two may be unified, that is, related information related to coordinates is converted into the same coordinate system. Specifically, the electronic device integrates the water supply network into a preset map, that is, takes the preset map as a base map. Based on the above, the electronic device may use the coordinate system of the preset map as a reference; the first coordinate information of the pipeline and the second coordinate information of the equipment are converted into a coordinate system of a preset map, and the converted first coordinate information and the converted second coordinate information are obtained.
And 112, the electronic equipment integrates the pipeline and the equipment into a preset map based on the converted first coordinate information and the converted second coordinate information to obtain an initial map.
After converting the coordinate information of the pipe and the device to the coordinate system of the preset map, the electronic device may integrate the pipe and the device into the preset map based on the converted coordinate information to obtain an initial map.
Specifically, integration refers to that a pipeline and equipment are represented by corresponding diagrams, and then the diagrams corresponding to the pipeline and the equipment are drawn to corresponding positions in a preset map according to the converted coordinate information, so that an initial map is obtained. In the drawing process, the electronic device can independently establish a layer for displaying the position distribution of different pipelines and different devices in a preset map.
Alternatively, the pipes may be represented by lines, and the lines of different thickness may represent pipes of different thickness; the device may be represented by a corresponding symbol in the engineering drawing. The specific illustration can be determined according to the actual practice, and is not limited in this embodiment.
And 113, the electronic equipment marks the first attribute information and the flow information, and the second attribute information and the acquired information in the initial map to obtain the pipe network map.
From the foregoing, it can be seen that the pipe network map is constructed to flexibly and conveniently monitor the target area. After the foregoing steps 111 and 112, only the pipes and devices are integrated in the preset map, that is, the electronic device can only locate different pipes and devices through the initial map, and cannot acquire the related data required for monitoring. In order to obtain relevant data required by monitoring, the electronic equipment can label the first attribute information and flow information of the pipeline, the second attribute information and acquisition information of the equipment into an initial map to obtain the pipe network map, so that the pipe network map has a space searching function required by a leakage monitoring process.
Specifically, for the pipeline, the first attribute information marked by the electronic equipment can include the length, the material, the pipe diameter, the burial depth and the like of the pipeline; the water flow of the pipelines with different first coordinate information and/or first attribute information can be different, so that the electronic equipment can also label the flow information of the pipelines. Wherein the traffic information belongs to dynamic information and can be determined by the related equipment connected with the traffic information.
For a device, the second attribute information that the electronic device labels for may include the type, specification, material, performance parameters, etc. of the device. The second coordinate information and/or the second attribute information may be different from each other, so that the acquired data of the devices may be marked in addition to the second attribute of the devices. Wherein the collected information also belongs to dynamic information, which can change along with the change of time.
In the embodiment of the application, the electronic equipment converts the coordinate information of the pipeline and the equipment into the coordinate system of the pipe network map, so that the pipeline and the equipment can be directly integrated into the pipe network map according to the converted coordinate information to obtain an initial map; because the initial map lacks relevant data required for leakage monitoring, in order to flexibly and conveniently monitor the target area, the electronic device can mark the first attribute information and the flow information of the pipeline, and the second attribute information and the acquisition information of the device in the initial map so as to obtain the pipe network map.
In some embodiments, the water supply network data may be determined by various systems of the water company, wherein the systems may include a GIS system, a mobile phone meter reading system, a revenue system, a remote centralized meter reading system, and the like. The coordinate systems adopted by the GIS system and the revenue system are different, so that the electronic equipment can firstly perform standardized processing on the accessed coordinate data for the data acquired from each system so as to ensure that the formats of the coordinate data are consistent. After standardization, consistency of coordinate data can be further checked, and equipment and/or pipelines with inconsistent coordinate data can be screened out for offline checking of water service companies, so that accuracy of access coordinates is ensured.
That is, the electronic device obtains source data from each system, performs standardized processing on the coordinate data in the source data to obtain processed source data, performs consistency examination on the processed coordinate data, and obtains the source data which is the water supply network data after the examination is correct.
In some embodiments, in order to improve the accuracy of the total differential water amount calculation, step 120 specifically includes:
step 121, the electronic device determines the frame selection area in response to the frame selection operation of the user.
The target area is the area that the user intends to monitor, and in principle, this area may be any area in the map of the pipe network. To facilitate user selection of the target area, the electronic device may provide framing tools, such as rectangular frames, circular manic frames, and arbitrary polygonal frames, through which the user may frame the area intended to be monitored.
However, in practical application, the network map has different scaling ratios limited by the visual area of the electronic device, and different resolutions exist under the different scaling ratios, so that the presented data information of the water supply network has differences. The difference is particularly apparent: as the scale increases, the geospatial area represented by each pixel on the map becomes smaller, meaning that the network map may present accurate data information for the water supply network. Conversely, as the scale decreases, the geospatial area represented by each pixel on the map becomes larger, meaning that the network map can only present rough data information for the water supply network.
If the frame selection operation is limited, namely the frame selection tool and the size corresponding to the frame selection tool are limited, under the condition of larger scaling, the area selected by the electronic equipment frame is smaller, but accurate data information of the water supply pipe network can be determined from the area, so that the water supply-water consumption relation in the area can be clarified, and the total differential water quantity in the area range can be calculated accurately. However, if the area selected by the frame becomes larger under a smaller scaling, the precise data information of the water supply pipe network cannot be displayed in the pipe network map, which is unfavorable for defining the water supply-water usage relationship in the area, and the calculation accuracy of the total differential water meter in the area is easy to be lower.
Therefore, after the user executes the frame selection operation, the electronic equipment can firstly determine the target area, determine the actually selected area in the pipe network map only according to the frame selection operation, and mark the actually selected area as the frame selection area, so that the better area is determined as the target area based on the frame selection area, and the accuracy of calculating the differential water quantity in the subsequent target area is improved.
Step 122, the electronic device determines a target pipe network level matched with the current scaling of the pipe network map.
As can be seen from the above step 121, the scale of the network map is positively correlated with the accuracy of the data information presented by the water supply network. In order to accurately determine the relationship between the scaling ratio and the accuracy of the data information, the electronic device may use the pipe network level of the water supply pipe network to represent the accuracy of the data information presented by the water supply pipe network, that is, the higher the pipe network level is, the more general the data information presented by the water supply pipe network is, the lower the pipe network level is, and the more specific and accurate the data information presented by the water supply pipe network is. Correspondingly, different pipe network grades can correspond to different scaling ratios, and the pipe network grades are inversely related.
After the electronic equipment determines the frame selection area, the current scaling of the pipe network map can be determined first, and the target pipe network level matched with the current scaling is further determined according to the corresponding relation between the pipe network level and the scaling of the pipe network map.
In some embodiments, to improve accuracy of pipe network grade determination, the electronic device may determine the pipe network grade from the minimum pipe diameter value within the visualization area. Namely, the larger the minimum pipe diameter value is, the more specific and accurate the corresponding data information is, and the lower the pipe network grade is; conversely, the smaller the minimum pipe diameter value is, the more general and rough the corresponding data information is, and the higher the pipe network grade is.
That is, when the electronic device determines the target pipe network level, the electronic device determines the minimum pipe diameter value in the visualization area under the current scaling, and then determines the pipe network level based on the corresponding relationship between the minimum pipe diameter value and the pipe network level.
Step 123, the electronic device determines the target area based on the target pipe network level and the frame selection area.
After the target pipe network level is determined, the electronic device can determine the preferred area as the target area according to the target pipe network level and the frame selection area. The data information of the water supply network in the target area is more specific and accurate, which is helpful for defining the relationship between water supply and water consumption, and further is helpful for accurately calculating the total differential water quantity in the target area.
In the embodiment of the application, after responding to the frame selection operation of a user, the electronic equipment generates a frame selection area; and then determining a target pipe network grade according to the current scaling of the pipe network map, determining a preferred area as a target area according to the target pipe network grade and the frame selection area, and carrying out leakage monitoring on the target area to determine the relationship between water supply and water consumption in the target area, thereby accurately calculating the total differential water quantity in the target area.
In some embodiments, to determine the preferred zone as the target zone, each pipe network grade may correspond to a pipe network final stage. For example only, assume that pipe network levels have five levels, one, two, three, four, and five levels, respectively. According to the relation between the concrete and the accuracy of the data information of the pipe network grade and the water supply pipe network, the data information corresponding to the pipe network of five grades is the most concrete and accurate, so that the pipe network final stage of each pipe network grade in the five pipe network grades can be set to be five grades.
Alternatively, it is considered that the pipe network grade calculation amount is large in which the pipe network final stage corresponding to the higher pipe network grade is directly set to the lowest stage. Therefore, in order to balance the calculated amount and the calculated accuracy, different pipe network grades can be firstly grouped, and different pipe network final stages can be arranged for different groups.
For example only, eight pipe network levels are provided, the first four pipe network levels may correspond to one group, the second four pipe network levels may correspond to one group, the last pipe network level of each of the first four pipe network levels is four, and the last pipe network level of each of the second four pipe network levels is eight.
Alternatively, in addition to the two modes described above, a different pipe network final stage may be associated with each pipe network level.
By way of example only, there are six pipe network levels, the pipe network final stage corresponding to the primary pipe network level is a secondary level, the pipe network final stage corresponding to the secondary pipe network level is a tertiary level, the pipe network final stage corresponding to the tertiary pipe network level is a quaternary level, the pipe network final stage corresponding to the quaternary pipe network level is a five-level, the pipe network final stage corresponding to the five-level pipe network level is a six-level, and the pipe network final stage corresponding to the six-level pipe network level is a six-level.
In some embodiments, the step 123 specifically includes:
and step 1231, the electronic equipment determines a target pipe network final stage corresponding to the target pipe network grade.
In view of the fact that each pipe network grade is provided with a pipe network final stage, the electronic equipment can determine the pipe network final stage corresponding to the target pipe network grade, namely the target pipe network final stage. Specifically, the electronic device stores a correspondence between the pipe network level and the pipe network final level in advance, and based on the correspondence and the target pipe network level, the target pipe network final level can be determined.
And step 1232, the electronic equipment enlarges the frame selection area according to the corresponding relation between the target pipe network grade and the target pipe network final stage.
After the target pipe network grade is determined, in order to accurately calculate the total differential water quantity in the target area, the electronic equipment can directly amplify the frame selection area from the target pipe network grade to the target pipe network final stage, so that more specific and accurate data information in the frame selection area can be presented.
Specifically, for the enlargement operation of the frame selection area, one way is to enlarge only the frame selection area, namely to realize the local enlargement of the pipe network map; another way is to enlarge the whole pipe network map and then determine the framed area therein. In either way, the electronic device may be front-end and back-end linked, i.e., the zoom-in operation is displayed simultaneously in the visualization area of the electronic device; of course, the processing may be performed only at the back end, and the enlargement operation is not displayed.
And step 1233, the electronic equipment determines a first local pipe network corresponding to the final stage of the target pipe network from the amplified frame selection area.
After the candidate region is enlarged, the electronic device may determine a local pipe network corresponding to the final stage of the target pipe network from the candidate region. Specifically, the electronic device can determine the local pipe network according to the pipe diameter corresponding to the target pipe network level, and the pipe diameter of the pipeline in the local pipe network is consistent with the pipe diameter corresponding to the target pipe network level. To facilitate distinguishing from subsequent local pipe networks, the local pipe network is referred to as a first local pipe network.
For example only, assuming the final stage of the target pipe network is the lowest stage, the pipe diameter corresponding to the lowest stage is 25 mm, the first local pipe network is determined from the enlarged candidate area, that is, the pipe network composed of pipes and equipment with pipe diameters of 25 mm is determined from the enlarged candidate area.
Step 1234, the electronic device filters the first local pipe network, and determines an area corresponding to the filtered first local pipe network as a target area.
In order to accurately calculate the total differential water volume, the electronic device may filter the first local pipe network to ensure that the water supply-water relationship in the first local pipe network is complete and clear.
It will be appreciated that in constructing a pipe network map, the electronic device may label the different pipes and devices according to the actual water supply-water relationship. Or the electronic equipment can store the actual water supply-water consumption relation, and call the relation when needed so as to filter the local pipe network and accurately determine the target area.
In some embodiments, the water supply-water relationship may also have a hierarchy depending on the water transfer characteristics of the pipe network from top to bottom. In particular, the hierarchy of water supply-water usage relationships may correspond to the pipe network levels such that even if the scale of the pipe network map is small, the accuracy of calculating the total differential water amount from the water supply-water usage relationships corresponding to the target pipe network levels is not too low. That is, in this case, the electronic device may directly take the frame selection area as the target area. It should be noted that the filtering step may be preserved in order to ensure that the water supply-water relationship at the current level is complete and well-defined.
In some embodiments, in the filtering step, the electronic device may add a missing water supply network or delete a portion of the water supply network according to the integrity of each set of water supply-water relationships in the first local network. The electronic equipment stores water supply-water use relations of all groups in the pipe network map, and partial water supply-water use relations can be determined in the local map. Because the framing operation is random, some water supply-water relationships are incomplete, and for each set of water supply-water relationships, the electronics can determine the corresponding integrity from the complete water supply-water relationships and the incomplete water supply-water relationships. Comparing each group of water supply-water consumption relations with a preset integrity threshold value, and deleting the corresponding water supply network from the first local network for water supply-water consumption relations with integrity lower than the integrity threshold value; for water supply-water relationships with integrity above the integrity threshold, a missing water supply pipe network may be added to the first local pipe network.
In some embodiments, to improve the computing efficiency, after performing step 122, the electronic device may directly perform the following steps to determine the target area:
and A1, determining a second local pipe network corresponding to the target pipe network grade from the frame selection area.
And step A2, filtering the second local pipe network to obtain a target area.
In this embodiment, in order to improve the calculation efficiency, the electronic device does not need to determine the final stage of the target pipe network, and amplifies the frame selection area according to the final stage of the target pipe network, but directly determines the second local pipe network corresponding to the grade of the target pipe network from the frame selection area, and filters the second local pipe network according to the water supply-water consumption relationship, so as to obtain the target area. The method for determining the second local pipe network and the method for filtering the second local pipe network can refer to the related steps, and are not described in detail in this embodiment.
In some embodiments, in addition to determining the target area in the above manner, as shown in fig. 3, a plurality of monitoring areas may be preset in the pipe network map according to the water supply-water usage relationship or in units of cells (the water supply-water usage relationship of one cell is complete and definite) so as to determine the target area based on the monitoring areas.
The monitoring areas can be determined according to the water supply-water consumption relationship, and can be determined by combining pipe network grades, namely, different monitoring areas can be set in different pipe network grades. Of course, in order to ensure the accuracy of the total differential water amount calculation in the target area, the electronic device may also fix the scaling of the pipe network map, and only set the monitoring area for the water supply pipe network with the smallest pipe network level.
For a pipe network map with a monitoring area, the electronic device can determine the target area by the following steps:
and B1, the electronic equipment responds to the selection operation of the user to determine the region of interest from the pipe network map.
In the pipe network map, a user can randomly select an area of interest. Accordingly, the electronic device may determine the region of interest from the pipe network map according to a selection operation by the user. The selection mode includes, but is not limited to, clicking, framing, etc.
And B2, the electronic equipment determines a target monitoring area with the largest area in the region of interest as a target area.
The monitoring area is arranged in the pipe network map, and after the interested area is determined, the electronic equipment can determine the target monitoring area with the largest area in the interested area as the target area. It can be understood that if different pipe network levels correspond to different monitoring areas, when determining the target area, the electronic device may determine the target pipe network level based on the scaling of the pipe network map, then determine the corresponding monitoring area based on the target pipe network level, and finally determine the target area from the corresponding monitoring area.
Optionally, if the user frames multiple monitoring areas at the same time, the electronic device may set a preset frame selection ratio first, and then determine a real frame selection ratio between the area of each monitoring area that is framed and the total area of the monitoring area, that is, how many monitoring areas are framed, and how many real frame selection ratios may be determined. Each real frame selection ratio is compared with a preset frame selection ratio, and a monitoring area with the real frame selection ratio being larger than the preset frame selection ratio can be used as a component part of a target area, namely a plurality of monitoring areas are included in one target area. Accordingly, for ease of calculation, the calculation result may be independently calculated for each monitoring area, rather than having a plurality of monitoring areas as a whole.
In some embodiments, the foregoing step 130 specifically includes:
step 131, the electronic device divides each target device into a water supply device and a water use device based on the device usage.
After the target device is determined, the electronic device may be classified into two categories, which are classified according to the device usage of the target device. One type is called water supply equipment and the other type is called water use equipment. Typically, the devices used for assessment, i.e. the assessment list, can be listed as water supply devices, while those used for large users, residential users, fire protection, greening, trade settlement, etc. are categorized as water use devices.
Step 132, the electronic device determines the total water supply amount based on each water supply device and determines the total water consumption amount based on each water supply device.
For each water supply device, the water supply amount of each water supply device in a preset time period can be determined, and the total water supply amount of each water supply device in the preset time period can be obtained by adding the water amounts of the plurality of water supply devices. For each water using device, the water consumption of the water using device in a preset time period can be determined, and the total water consumption of each water using device in the preset time period can be obtained by adding the water consumption of the water using devices.
Step 133, determining the total differential water amount based on the total water supply amount and the total water consumption amount.
After the total water supply amount and the total water consumption are determined, the electronic equipment can subtract the total water consumption from the total water supply amount to obtain the total differential water consumption in a preset time period. Based on the total differential water volume, the electronic device can further analyze the water volume leakage condition in the target area.
Merely by way of example: assume that there are two assessment tables, one water inlet table a and one water outlet table B, in the target area, and the following types of users and devices: a large user a, 500 resident users b, a fire meter c, and a greening meter d.
First, the total water supply amount, which represents the amount of water from the water inflow table a to the water outflow table B, was calculated by a-B. Then, the total water consumption is calculated, and the total water consumption is the sum of all water consumption devices, including the water consumption of the large user a, the resident user b, the fire meter c and the greening meter d, and is calculated through a+b+c+d. Finally, the total differential water amount is calculated: (A-B) - (a+b+c+d).
The calculated total differential water quantity represents the difference between inflow water and outflow water in the target area, and is helpful for identifying the leakage condition of the water supply network so as to carry out maintenance and improvement of the water supply network.
In some embodiments, when the preset time period is daily, in order to increase the water amount calculation of the water using device in the preset time period, the electronic device may use different calculation modes for different device types: and for the remote transmission large meter, acquiring net accumulated data of large meter equipment through a remote transmission acquisition platform, and then calculating the water consumption of the day by using the difference value of net accumulation of the zero points before and after the day. For the remote transmitting small meter, the positive accumulation data is acquired through the remote transmitting acquisition platform, and then the positive accumulation of the current day is subtracted from the positive accumulation of the previous day to obtain the water consumption of the current day. For a non-remote meter, a mobile phone meter reading system is adopted to acquire manual meter reading data, then the last meter reading data is subtracted from the current meter reading data and divided by the number of days of the interval, and the average water consumption per day is calculated.
In this embodiment, the daily water consumption of each water consumption device may be calculated according to the data source and characteristics of each device type, so as to obtain accurate water consumption data.
In some embodiments, to improve the efficiency of leak detection, for the target area determined in any of the above embodiments, the electronic device may store its history determination information according to a history record, where the history determination information includes devices within the target area. Therefore, before the user selects, the target area can be recommended to the user according to the related information, such as the scaling, of the current pipe network map, and after the user selects the target area, the electronic equipment can directly calculate the total differential water quantity in the target area according to the historical determination information, so that the leakage monitoring efficiency is improved. Of course, in order to reduce memory waste, when storing the history determination information, recording may be performed according to the determination frequency of the target area, that is, for the target area whose determination frequency is greater than the preset frequency threshold, the history determination information may be stored.
Optionally, the target area focused on by the user may be determined, so that a collection function may be provided for the user, for example, as shown in fig. 3, the determination information corresponding to the target area focused on by the user is stored separately, so that the user can determine the leakage condition of the water amount in each target area in the favorites in a targeted manner.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic of each process, and should not limit the implementation process of the embodiment of the present application in any way.
