TECHNICAL FIELD
[0001] The present disclosure relates to the technical field of intelligent maintenance of construction engineering, and particularly relates to a concrete floor maintenance system. BACKGROUND
[0002] After the pouring of the concrete floor is completed, timely and reasonable maintenance is a key link to ensure normal hardening, improve strength, durability and use performance of the concrete floor. If the maintenance is improper, it is easy to cause quality problems such as cracks on the surface of the concrete floor and insufficient strength, which seriously affects the performance and service life of the floor.
[0003] However, in an open or ventilated environment, air flow will significantly affect the evaporation rate of the floor surface. Especially in the presence of large wind speed or wind direction changes, especially for the concrete floor as a large-area horizontal structure, the wind field distribution has significant spatial characteristics: under the condition of no shelter, when the wind flows across the floor surface, the edge area is easy to form a local acceleration zone and a vortex zone due to the boundary effect, resulting in a significantly higher water evaporation rate than the central area. In addition, the wind direction change will dynamically change the windward / leeward state of different areas of the floor, further exacerbating the uneven distribution of water.
[0004] In the prior art, the maintenance of the concrete floor is mostly carried out by whole-time spraying or spraying according to the overall humidity control. Even if the influence of wind is considered, only the wind speed is taken as a global unified parameter, and the influence of uneven distribution of wind on local evaporation is not considered. It is difficult to carry out fine control according to the differences in wind speed or wind direction of different areas, resulting in that in the construction environment with large wind force, the maintenance effect is difficult to guarantee. SUMMARY
[0005] The present disclosure provides a concrete floor maintenance system to solve the problem that in the prior art, the wind speed is taken as a global unified parameter to adjust the humidity of the concrete floor, and the differences in humidity of the concrete floor caused by uneven distribution of wind are ignored, so that the maintenance effect cannot be ensured.
[0006] The present disclosure provides a concrete pavement maintenance system, comprising: a sensing unit comprising a plurality of sensing sub-units, each of the sensing sub-units being arranged in a partition to monitor a maintenance judgment parameter of a concrete pavement in each of the partitions; the maintenance judgment parameter comprising humidity, wind speed, temperature, ambient humidity and ambient temperature of a surface of the concrete pavement; a spraying array comprising a plurality of spray heads, adapted to spray water to the concrete pavement in each of the partitions to maintain the humidity of the concrete pavement within a preset range; a controller adapted to receive the maintenance judgment parameter of each of the partitions, and control the spraying array to spray water to the partition in a case that the humidity of the concrete pavement in the partition is less than a maintenance humidity threshold or a predicted evaporation rate of the concrete pavement in the partition is greater than a preset evaporation rate; wherein the predicted evaporation rate is calculated based on the wind speed, temperature, ambient humidity and ambient temperature of the surface of the concrete pavement.
[0007] According to the concrete pavement maintenance system provided by the present disclosure, the sensing sub-units are further adapted to monitor the wind direction of each of the partitions.
[0008] According to the concrete pavement maintenance system provided by the present disclosure, the controller is adapted to control the spray head to reduce the water outlet pressure or pause water spraying in a case that the water spraying direction of the spray head is opposite to the wind direction.
[0009] According to the concrete pavement maintenance system provided by the present disclosure, the spray head is adjustable in direction; in a case that the included angle between the water spraying direction of the spray head and the wind direction is within a preset angle range, the controller controls the spray head to adjust the spraying direction and the water outlet pressure to compensate for the spray offset caused by the lateral component of the wind direction perpendicular to the water spraying direction.
[0010] According to the concrete pavement maintenance system provided by the present disclosure, in a case that the wind speed exceeds a wind speed warning threshold, the controller controls the spraying array to stop water spraying.
[0011] According to the concrete pavement maintenance system provided by the present disclosure, further comprising a windproof roller blind arranged at the edge of the concrete pavement; wherein in a case that the wind speed exceeds a wind speed warning threshold, the windproof roller blind is unfolded.
[0012] According to the concrete pavement maintenance system provided by the present disclosure, in a case that the temperature of the concrete pavement exceeds a first temperature threshold, the spraying array sprays water to reduce the temperature of the concrete pavement; in a case that the temperature of the concrete pavement is lower than a second temperature threshold, the spraying array stops water spraying; wherein the first temperature threshold is greater than the second temperature threshold.
[0013] The concrete pavement maintenance system provided by the present disclosure further comprises a heating unit, which comprises a plurality of heating sub-units arranged in the concrete pavement of each of the sub-zones; in the case that the temperature of the concrete pavement of the sub-zone is detected to be lower than a third temperature threshold, the heating sub-unit heats the concrete pavement of the sub-zone; wherein the third temperature threshold is less than or equal to the second temperature threshold.
[0014] The concrete pavement maintenance system provided by the present disclosure further comprises a plurality of thermal blankets arranged in each of the sub-zones; wherein in the case that the temperature of the concrete pavement of the sub-zone is detected to be lower than the third temperature threshold, the thermal blanket is unfolded and covers the concrete pavement to maintain the temperature of the concrete pavement in the sub-zone.
[0015] The concrete pavement maintenance system provided by the present disclosure, the sensing sub-unit is further applicable to detect the strength of the concrete pavement of the sub-zone; wherein in the case that the strength of the concrete pavement meets the preset strength requirement, the maintenance of the concrete pavement is terminated.
[0016] The concrete pavement maintenance system provided by the present disclosure, the sensing unit monitors the maintenance judgment parameters including the wind speed of the surface of the concrete pavement in each sub-zone. For a large area of concrete pavement, the wind speed flowing through each sub-zone is unevenly distributed in space, and the evaporation rate brought to each sub-zone also naturally exists differences. The greater the wind speed, the greater the general evaporation rate. The predicted evaporation rate in each sub-zone is calculated by the maintenance judgment parameters. When the predicted evaporation rate in a sub-zone is greater than the preset evaporation rate, water is sprinkled in the sub-zone to prevent the evaporation rate in the sub-zone from being too high to cause the concrete pavement in the sub-zone to lose water too fast and affect the maintenance effect.

DETAILED DESCRIPTION
[0019] In order to make the objects, technical solutions and advantages of the present disclosure clearer, the technical solutions in the present disclosure will be clearly and completely described below with reference to the drawings in the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present disclosure.
[0020] In the prior art, in the consideration of various environmental factors for the maintenance of the concrete floor, only the wind speed is often considered as a global variable. However, for a large area of the concrete floor, the wind speed distribution flowing through the floor is often uneven, especially in the mountainous or canyon topography, the wind speed in the windward area and the leeward area is often very different. If the wind speed is considered as a global variable, the final maintenance result of the concrete floor will be affected.
[0021] Therefore, the present disclosure provides a concrete floor maintenance system.
[0022] Figure 1 is a schematic diagram of a concrete floor maintenance system according to an illustrative embodiment of the present disclosure; Figure 2 is a schematic diagram of a sensing subunit of the layout of the concrete floor maintenance system according to an illustrative embodiment of the present disclosure.
[0023] As shown in Figure 1 and Figure 2 , the concrete floor maintenance system includes a sensing unit, a spraying array and a controller. The sensing unit includes a plurality of sensing subunits, each of which is arranged in a partition to monitor the maintenance judgment parameters of the concrete floor in each partition; the maintenance environment parameters include the humidity, wind speed, temperature, environmental humidity and environmental temperature of the surface of the concrete floor.
[0024] The spraying array includes a plurality of spray heads, which are suitable for spraying water to the concrete floor in each partition to maintain the humidity of the concrete floor within a preset range.
[0025] The controller is suitable for receiving the maintenance judgment parameters of each partition, and controlling the spraying array to spray water to the partition in the case that the humidity of the concrete floor in the partition is less than a maintenance humidity threshold or the predicted evaporation rate of the concrete floor in the partition is greater than a preset evaporation rate; wherein the predicted evaporation rate is calculated based on the wind speed, temperature, environmental humidity and environmental temperature of the surface of the concrete floor.
[0026] According to the embodiments of the present disclosure, the sensing subunit includes a floor humidity sensor arranged on the surface of the concrete floor, a temperature sensor, an environmental humidity sensor arranged above the concrete floor and a wind speed sensor.
[0027] Preferably, the wind speed sensor can be arranged at a height of 1.5 to 2.0 meters above the concrete pavement, because at a lower height, the wind speed can be disturbed by the ground roughness or obstacles, and if at a higher height, the wind speed is closer to the free wind flow, therefore, arranging the wind speed sensor at a height of 1.5 to 2.0 meters above the concrete pavement can more accurately measure the wind speed data that can reflect the evaporation rate of the concrete pavement surface.
[0028] According to an embodiment of the present disclosure, the spray head can be a rotating spray head for covering the surface of the entire concrete pavement in the partition.
[0029] According to an embodiment of the present disclosure, each spray head can be arranged on a movable water supply main pipe, and the spray head can be fully covered in the entire range of the concrete pavement by moving the main pipe.
[0030] According to an embodiment of the present disclosure, the main pipe can be erected on a track, and the main pipe and the track are coupled by rollers arranged below the main pipe, and when it is necessary to move the spray head, the rollers are driven by a motor to move the main pipe, and thus the spray head reaches the area where water is needed.
[0031] According to an embodiment of the present disclosure, when the predicted evaporation rate is greater than the preset evaporation rate, it means that the water evaporation rate of the concrete pavement surface is too fast at this time, even if the humidity sensor on the surface has not detected that the humidity of the concrete pavement is less than the maintenance humidity threshold, there is a risk of excessive water loss, therefore, water can be sprayed in advance according to the predicted evaporation rate to prevent the concrete pavement from being excessively dry.
[0032] According to an embodiment of the present disclosure, the predicted evaporation rate E can be expressed as:
[0033] wherein, e s The saturated water vapor pressure of the concrete pavement surface can be expressed as:
[0034] wherein, , T s,max and T s,min are the highest temperature and the lowest temperature collected on the concrete pavement surface within a preset sampling time, respectively.
[0035] The actual water vapor pressure of the environment e a is:
[0036] wherein, and is the ambient temperature, and RH is the ambient humidity.
[0037] f(u) For the wind speed function, it can be expressed as:
[0038] In the formula, u is the wind speed.
[0039] k is an empirical coefficient, which is dynamically adjusted according to the concrete strength grade, water-binder ratio, admixture type, design thickness of the floor and curing age. For example, for high-strength low-water-binder ratio concrete or thin plate structure, due to the limitation of internal water migration, k the value is correspondingly reduced; and for ordinary strength, thicker floor, k the value is correspondingly increased.
[0040] According to an embodiment of the present disclosure, the preset evaporation rate can be determined according to the location of the partition, for example, for the partition located on the windward side or the edge area, since water loss is relatively easy, the preset evaporation rate can be appropriately reduced to trigger the water spraying in advance.
[0041] Through the above setting mode, the concrete floor is divided into partitions for curing, and in the case that the predicted evaporation rate of the partition is greater than the preset evaporation rate or the humidity is less than the curing temperature threshold, the water spraying array is controlled to spray water. Since the partitions are processed, the uneven evaporation of each partition caused by the difference in wind speed is prevented, and the uneven distribution of the humidity of the concrete floor caused by the uneven evaporation is further prevented, thereby ensuring the consistency and stability of the curing of the concrete floor.
[0042] In an illustrative embodiment, the controller can adjust the water flow rate of the spray head according to the difference between the humidity of the concrete floor and the curing humidity threshold. The water flow rate can be achieved by adjusting the rotating speed of the spray pump, controlling the opening and closing duty cycle of the electromagnetic valve, or adjusting the opening degree of the spray hole of the spray head, so that the water spraying amount matches the dry and wet degree of the concrete floor, and excessive water spraying or insufficient water spraying is avoided.
[0043] In an illustrative embodiment, the sensing subunit is also suitable for monitoring the wind direction of each partition.
[0044] In an illustrative embodiment, the controller is suitable for controlling the spray head to reduce the water outlet pressure or suspend water spraying when it is detected that the water spraying direction of the spray head is opposite to the wind direction.
[0045] According to an embodiment of the present disclosure, since the direction of water spraying is opposite to the direction of incoming wind, in order to prevent the sprayed water from being blown away by strong wind, the water outlet pressure should be reduced or the water spraying should be suspended, so as to prevent the sprayed water from being blown to other partitions by the wind.
[0046] In one illustrative embodiment, the nozzle's direction is adjustable. When the angle between the nozzle's spray direction and the wind direction is detected to be within a preset angle range, the controller controls the nozzle to adjust the spray direction and water pressure to compensate for the spray offset caused by the lateral component of the wind direction perpendicular to the spray direction.
[0047] According to embodiments of this disclosure, the nozzle can employ an electrically adjustable structure, such as adjusting the nozzle's direction via a stepper motor, servo motor, or electronically controlled oscillation mechanism. When the angle between the current wind direction and the nozzle's intended spray direction is detected to be within a preset angle range (e.g., 20°–60°), the controller controls the nozzle's rotation mechanism based on this angle, causing the nozzle's spray direction to deflect to a lateral component direction opposite to the wind direction, thereby compensating for the wind-induced deviation.
[0048] According to embodiments of this disclosure, the controller can synchronously adjust the output pressure of the spray pump according to the wind speed: when the wind speed is high, the water pressure is increased to enhance the water flow inertia and reduce the deviation; when the wind speed is low, the water pressure is reduced to avoid excessive scouring of the floor surface.
[0049] Through the above adjustments, the sprinkler head can still cover the target watering area under different wind conditions, achieving dynamic compensation for spray deviation caused by crosswinds.
[0050] In one illustrative embodiment, when the wind speed is detected to exceed the wind speed warning threshold, the controller controls the sprinkler array to stop spraying water.
[0051] According to embodiments of this disclosure, in cases of excessive wind speed, the water spray may deviate from its designated zone or be scattered by the strong wind, thus compromising the quality of maintenance. Therefore, it is necessary to stop spraying water.
[0052] According to embodiments of this disclosure, when the wind speed exceeds the wind speed warning threshold, the windproof membrane can also be laid on the concrete floor to prevent excessive evaporation.
[0053] According to embodiments of this disclosure, water spraying is considered only after the wind speed has been below the wind speed warning threshold for a preset duration.
[0054] In another illustrative embodiment, the concrete floor curing system also includes a windproof roller shutter installed at the edge of the concrete floor. The windproof roller shutter deploys when the wind speed is detected to exceed a wind speed warning threshold.
[0055] According to embodiments of this disclosure, the windproof roller shutter can be deployed when the wind speed exceeds the wind speed warning threshold to reduce airflow disturbance and local evaporation rate differences at the edge of the floor, thereby avoiding local drying or water mist dispersion and improving the stability of maintenance.
[0056] Taking a rectangular concrete floor as an example, windproof roller shutters can be installed on all four sides of the concrete floor. When the wind speed in a certain direction exceeds the wind speed warning threshold, the windproof roller shutter on the windward side will unfold to reduce the impact on the curing of the concrete floor.
[0057] In one illustrative embodiment, when the temperature of the concrete floor is detected to exceed a first temperature threshold, the spray array sprays water to lower the temperature of the concrete floor. When the temperature of the concrete floor is detected to be below a second temperature threshold, the spray array stops spraying water. The first temperature threshold is greater than the second temperature threshold.
[0058] According to embodiments of this disclosure, if the temperature of the concrete floor exceeds a first temperature threshold, it indicates that the temperature of the concrete floor is too hot and water needs to be sprayed to reduce the temperature of the concrete floor; if the temperature of the concrete floor is below a second temperature threshold, it indicates that the temperature of the concrete floor is too low and further spraying of water may result in the concrete floor having too low strength.
[0059] In one illustrative embodiment, the concrete floor curing system may also include a separate spray cooling device, comprising multiple fine water mist nozzles, which spray water onto the concrete floor to reduce the temperature of the concrete floor when the temperature of the concrete floor is detected to exceed a first temperature threshold.
[0060] In one illustrative embodiment, the concrete floor curing system further includes a heating unit comprising multiple heating sub-units disposed in each zone of the concrete floor. When the temperature of the concrete floor in a given zone is detected to be below a third temperature threshold, the heating sub-units heat the concrete floor in that zone. The third temperature threshold is less than or equal to a second temperature threshold.
[0061] According to embodiments of this disclosure, the heating subunit may be an electric heater such as an electric heating cable, electric heating film, or electric heating rod embedded beneath the concrete. When the temperature is below a third temperature threshold, the heating subunit is energized for heating.
[0062] According to embodiments of this disclosure, the heating subunit may include a heat flow channel or a heat medium pipeline to heat the concrete floor by circulating warm water or hot air.
[0063] In one illustrative embodiment, the concrete floor curing system also includes multiple insulation blankets installed in each zone. When the temperature of the concrete floor in a zone is detected to be below a third temperature threshold, the insulation blankets are deployed and cover the concrete floor to maintain the temperature of the concrete floor in that zone.
[0064] According to an embodiment of this disclosure, the thermal insulation blanket is wound on a spool. When the thermal insulation blanket needs to be unfolded, the spool rolls in a predetermined direction to unfold the thermal insulation blanket and cover the concrete floor.
[0065] In another illustrative embodiment, the concrete floor curing system includes multiple retractable insulation covers for lowering when the temperature of the concrete floor in a certain zone falls below a third temperature threshold, in order to maintain the temperature of the concrete floor in that zone.
[0066] In one illustrative embodiment, the sensing subunit is also adapted to detect the strength of the concrete floor in its designated zone. Wherein, if the strength of the concrete floor meets a preset strength requirement, the curing of the concrete floor is terminated.
[0067] According to embodiments of this disclosure, the temperature history of concrete can be continuously recorded by temperature sensors embedded in each partition, and the maturity value of concrete can be calculated by mathematical models such as the Nurse-Saul equation. The strength of concrete can be determined by the relationship curve between maturity and strength.
[0068] According to embodiments of this disclosure, strain sensors can also be embedded in each partition to calculate the strength growth trend based on changes in internal strain of the concrete.
[0069] According to embodiments of this disclosure, the strength of concrete can also be measured by ultrasonic waves.
[0070] In one illustrative embodiment, the controller is also adapted to record operational data during the maintenance process, including temperature and humidity of each zone, wind speed, predicted evaporation rate, equipment operating status, and number of water sprays, in order to form a maintenance data archive for subsequent analysis and optimization.
[0071] In one illustrative embodiment, the controller is equipped with a preset curing parameter standard library. This library can be categorized and set according to the type of concrete, mix proportion, construction season, and regional climate, including humidity thresholds, temperature control ranges, preset strength requirements, and wind speed intervention thresholds for each curing stage. The controller can compare and analyze the collected monitoring data such as temperature, humidity, wind speed, and strength with the parameters in the standard library to determine the corresponding curing control parameters, such as temperature thresholds and preset evaporation rates. When abnormal parameters are detected, the controller will issue an early warning or adjust the control command, while simultaneously recording the operating data.
[0072] To further illustrate the specific process of curing concrete floors using the aforementioned curing system, the following specific examples are provided: Example 1 Concrete floor curing in high-temperature summer conditions In summer, the ambient temperature is high during the day, the sunlight is strong, and the relative humidity of the air is low. After the concrete is poured, the surface moisture evaporates quickly, which can easily lead to surface shrinkage cracks due to excessive water loss. In addition, the high temperature environment may cause the internal temperature of the concrete to rise, which will affect the normal progress of the hydration reaction.
[0073] For this specific working condition, the maintenance steps are as follows: After the concrete floor is poured and before initial setting, curing zones are divided into 10m x 10m grids, and sensor sub-units are installed in each zone. Each sensor sub-unit includes multiple humidity sensors, embedded on the floor surface and at different depths, to monitor surface and internal humidity changes; temperature sensors to monitor surface and internal temperatures as well as ambient temperature; strength sensors evenly distributed across the floor area to track concrete strength development in real time; and wind speed and direction sensors mounted on a 2-meter-high support. All sensor data is uploaded to the controller in real time via a stable data transmission method. After equipment debugging and parameter initialization, the entire curing system is started.
[0074] During system initialization, the controller loads concrete curing parameter standards for high-temperature summer environments. These standards not only set humidity maintenance targets and temperature control limits for different curing stages, but also explicitly include wind speed as a key intervention condition.
[0075] During the operation of the maintenance system, each sensor continuously collects data at a 5-minute interval. First, wind speed is prioritized: if the wind speed is within a safe range, the predicted evaporation rate for the current and short future is calculated based on the maintenance judgment parameters, and a precise spraying command is generated accordingly. Simultaneously, it is assessed whether the spray array needs to be activated to suppress excessively high ambient temperatures. If the wind speed exceeds the wind speed warning threshold, the system immediately suspends all spraying operations to prevent water mist from being blown away by strong winds, causing water waste and exacerbating local water loss. At the same time, it determines whether to maintain monitoring or activate cooling measures based on the temperature status.
[0076] As the curing time progresses, the strength sensor continuously provides data on the development of concrete strength. Based on this data, the controller dynamically adjusts the subsequent curing strategy, gradually reducing intervention during the stabilization period. This ensures that the concrete achieves uniform and controllable strength growth under high temperature conditions, effectively suppressing the generation of temperature stress and drying shrinkage cracks.
[0077] Example 2 Concrete floor curing in low-temperature winter environments Winter temperatures are low and often accompanied by strong winds. Strong winds accelerate the evaporation of moisture from the concrete surface, while low temperatures slow down the hydration reaction of concrete. If the temperature is too low, the concrete may freeze, affecting its strength development and durability.
[0078] After the concrete floor is poured and before final setting, the area is divided into 8m x 8m zones, and sensor subunits are installed. Considering the impact of low temperatures on electronic components, all sensors are industrial-grade wide-temperature (-40℃ to +85℃) sensors with external windproof and heat-insulating shells. Humidity sensors are installed on the floor surface and at different depths to monitor humidity changes in various locations; temperature sensors monitor the temperature of the floor surface, interior, and surrounding environment; strength sensors are evenly embedded in the floor to monitor the concrete strength development in real time. The wind speed sensor installation height is adjusted to 1.8 meters, and an anti-freeze coating is added; the strength sensor uses an embedded probe based on changes in concrete resistivity to ensure data stability at low temperatures. The data transmission module uses a low-temperature resistant LoRa communication protocol to ensure signal stability. All devices are connected to the controller, and the system is started after debugging.
[0079] The controller is loaded with concrete curing parameter standards for winter high wind environments. The standard stipulates that water spraying is prohibited when the ambient temperature or the temperature of the concrete floor surface is below a certain critical value to prevent water from freezing and damaging the concrete structure; when the temperature drops further below the freezing point, insulation measures must be activated; and when the wind speed exceeds the set threshold, the system not only suspends all actions that may disturb the insulation layer (such as spraying or moving equipment), but also automatically triggers the windproof response mechanism.
[0080] During the operation of the curing system, the sensing subunit continuously collects data and transmits it to the controller. If both low temperature and strong wind signals are detected simultaneously, the insulation and windproof linkage strategy will be prioritized: an automatic roll-up mechanism will cover the floor surface with insulation blankets or covers to reduce heat loss; at the same time, windproof curtains will rise from the windward side of the floor to form a local windbreak, effectively reducing wind-induced evaporation and convective heat transfer. When the ambient temperature rises and the wind weakens, meeting the conditions for concrete hydration, the controller will issue a command to retract the insulation blankets. When humidity is insufficient, the sprinkler system will spray water appropriately during periods of lower wind to replenish moisture.
[0081] During the curing period, the system flexibly adjusts the curing measures according to changes in wind force and temperature. Spraying is suspended and heat preservation is strengthened during periods of strong wind. Watering is added when the temperature is slightly higher and the wind force is lower to ensure that the concrete is always in a suitable curing environment.
[0082] As can be seen from the above, the concrete floor curing system provided in this disclosure has at least the following beneficial effects: (1) By monitoring various environmental parameters such as humidity, wind speed, and temperature of the concrete floor in real time, and automatically adjusting the water spraying, heating, and spraying stop operations based on these data, precise control is achieved. The system can be adjusted according to the actual needs of different zones to ensure accurate and uniform water supply during the curing process, thereby improving curing precision and efficiency; (2) This system automatically adjusts the curing strategy during the curing process by comprehensively considering different environmental factors (such as temperature, humidity, wind speed, etc.) to ensure that the concrete floor is always in a suitable curing state under different weather conditions. The monitoring and control of temperature and wind speed avoids the impact of extreme weather conditions on the curing effect and maintains the stability and consistency of the curing. (3) Through intelligent control and automatic adjustment, the system effectively reduces unnecessary water spraying and energy consumption. Precise water volume and temperature control reduces water waste and heating requirements, lowers equipment operating costs, and avoids problems of over-maintenance or under-maintenance, reducing later repair costs.
[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this disclosure.
