[0004] When rainwater drips along the eaves or walls to the ground, water stains will appear on the ground, causing people to slip when passing by. Summary of the invention

[0005] In order to reduce the probability of people slipping when passing by and improve the safety of drainage in green and energy-saving building construction, the present invention provides a green and energy-saving building drainage method, system and terminal.

[0006] In the first aspect, the present invention provides a green and energy-saving drainage method for building construction, which adopts the following technical solution: A green and energy-saving drainage method for a building, comprising: Obtain rainfall and precipitation image information for green and energy-saving housing buildings; Determine the rain slope based on the precipitation image information and the preset rain characteristics; Determine the shielding number based on the rainfall and the preset benchmark rainfall; Determine the shielding slope based on the rain slope; The extension length is determined according to the shielding inclination and the preset drain outlet position, and the preset shielding device is controlled to extend the shielding according to the shielding number, extension length and shielding inclination.

[0007] By adopting the above technical solution, the rainfall and precipitation image information are analyzed to obtain the shielding number, extension length and shielding inclination, and the shielding device is controlled to shield the rainwater and guide the rainwater to the drain outlet, thereby reducing the occurrence of water stains on the ground between the drain outlet and the house, reducing the probability of people slipping when passing by, and improving the safety of drainage in green and energy-saving house buildings.

[0008] Optionally, the method after determining the extension length includes: Determining the extension end according to the extension length and a preset reference shielding position; Determine the drip height based on the extended end and the preset drain outlet position; Determine the offset distance by a preset detection method according to the drop height; Determine the drop position based on the extended end and the offset distance; When the dripping position does not fall into the preset drain outlet range, the straight-line distance between the dripping position and the drain outlet range is calculated, and the minimum straight-line distance is used as the adjustment distance; When the adjustment distance is a positive value, the occlusion tilt is updated according to the adjustment distance; When the Based on Adjustment Distance is a negative value, the extension length is updated based on the adjustment distance.

[0009] By adopting the above technical solution, the dripping position of the water drop on the shielding device is obtained by analyzing the extended end and the dripping height, and the extension length is updated by adjusting the positive and negative conditions of the distance, thereby improving the accuracy of the shielding device in guiding the water droplets to drip to the drain outlet.

[0018] Optionally, the method before extending and shielding by using the extension length and the shielding inclination includes: Obtain the occlusion image information around the green energy-saving house building according to the detected wind direction; Determine the occlusion height, occlusion area and interval distance according to the occlusion image information; Determine the benchmark mark height based on the rain slope, the interval distance and the preset benchmark shielding height; According to the occlusion height, an occlusion height exceeding the reference mark height is selected as the mark occlusion height, and the occlusion area of ​​the mark occlusion height is selected as the mark occlusion area; The shielding position is determined according to the marked shielding area and the rain inclination, and the shielding device at the shielding position is controlled to extend the shielding according to the extension length and the shielding inclination.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] A green energy-saving house building drainage method analyzes the rainfall and the inclination of rainwater in the current area of ​​the green energy-saving house building to control a shielding device to guide rainwater to a drain outlet, and further adjusts the shielding device according to wind conditions during rainfall, water droplets dripping on the shielding device, water flow on the shielding device, and the condition of shielding objects shielding rainwater, thereby reducing water stains on the ground between the drain outlet and the house and reducing the possibility of people slipping when passing by, so as to improve the safety of green energy-saving house building during drainage.

[0027] Reference Figure 1 The present application discloses a green and energy-saving drainage method for a building, comprising the following steps: Step S100: Obtaining rainfall and precipitation image information of green energy-saving building.

[0028] The rainfall refers to the rainfall in the area where the green energy-saving house is located, and can be used as the rainfall by querying the parameters of rainfall detected by the meteorological station in the area where the green energy-saving house is located.

[0029] The precipitation image information refers to the images around the green energy-saving house building taken by a camera when it rains in the area where the green energy-saving house building is located.

[0030] Step S101: determining the rain slope according to the precipitation image information and the preset rain characteristics.

[0031] Rainwater characteristics are the shape characteristics of rainwater set by technicians. Rainwater inclination refers to the maximum inclination angle of rainwater when it rains in the area where green energy-saving housing buildings are located. The maximum angle obtained by comparing the line corresponding to the rainwater characteristics in the precipitation image information with the vertical line is used as the rainwater inclination.

[0032] Step S102: determining a shielding number according to the rainfall and a preset reference rainfall.

[0033] The shielding device includes a telescopic rod, a roller, and a baffle plate for protecting the roller and connected to the eaves of the green energy-saving house building. The shielding device is evenly arranged at the eaves of the green energy-saving house building.

[0034] Two rollers are arranged in a shielding device and are installed at intervals along the extension direction of the baffle. A curtain made of sodium polyacrylate composite fiber is wound on one roller, and a steel curtain made of multiple steel materials is wound on the other roller. A connector for connecting a telescopic rod is arranged at one end of the curtain and the steel curtain. The connector is hollow and has multiple air holes for blowing horizontally toward the eaves. A marking blowing device is arranged on the connector, and the marking blowing device corresponds to the air holes one by one. The marking blowing device can be a small cross-flow fan. A gap for passing rainwater is provided between the part of the connector where the marking blowing device is arranged and the part where the curtain or steel curtain is connected.

[0035] The telescopic rod is hollow and one end of the telescopic rod for extension is provided with a blowing device, which can be an air pump connected to the telescopic rod.

[0036] The reference rainfall is the reference rainfall set by the technicians for the shielding device to switch the material. The shielding number refers to the number of the connector on the corresponding roller connected to the telescopic rod, and the shielding number corresponds to the material wrapped on the roller. When the rainfall is not less than the reference rainfall, the number corresponding to the curtain is selected as the shielding number. When the rainfall is greater than the reference rainfall, the number corresponding to the steel curtain is selected as the shielding number.

[0037] Step S103: Determine the shielding inclination according to the rain inclination.

[0038] The reference shielding height is the height that the shielding device needs to shield, which is set by the technician. The shielding inclination refers to the angle when the shielding device is extended. The shielding inclination is matched from the preset inclination database through the rainwater inclination. The inclination database contains the correspondence between the rainwater inclination and the reference shielding height. The inclination database is set manually and will not be described in detail here.

[0039] Step S104: Determine the extension length according to the shielding inclination and the preset drain outlet position, and control the preset shielding device to extend the shielding according to the shielding number, extension length and shielding inclination.

[0040] The drain outlet position is the position of the drain outlet center set by the technician. The extension length refers to the length that the telescopic rod needs to extend. The end position of each extended length is obtained by blocking the inclination, and the extension length corresponding to the end position in a vertical line with the drain outlet position is taken as the extension length, and then the shielding device is controlled to extend and shield according to the shielding number, extension length and shielding inclination.

[0041] Reference Figure 2 , methods for determining the extension length include: Step S200: determining the extension end according to the extension length and a preset reference shielding position.

[0042] The reference shielding position is the position of the shielding device installed set by the technician. The extended end refers to the position of the end of the shielding device extended. The extended end is calculated by the reference shielding position and the extended length. The calculation method of the extended end is common knowledge of those skilled in the art and will not be described here.

[0043] Step S201: Determine the drip height according to the extended end and the preset drain outlet position.

[0044] The drip height refers to the height of rainwater dripping from the extended end, and is calculated as the straight-line distance between the extended end and the drain outlet.

[0045] Step S202: Determine the offset distance according to the drop height by using a preset detection method.

[0046] The detection method refers to a method for detecting the distance of water drop deviation. The deviation distance refers to the maximum distance that rainwater at the extension end deviates from the drop. The deviation distance is obtained by analyzing the drop height and the detection method.

[0047] Step S203: determining the dripping position according to the extended end and the offset distance.

[0048] The dripping position refers to the position where the rainwater at the extension end is deflected when dripping. The dripping position is calculated by the extension end and the offset distance.

[0049] Step S204: when the dripping position does not fall into the preset drain outlet range, the straight-line distance between the dripping position and the drain outlet range is calculated, and the minimum straight-line distance is used as the adjustment distance.

[0050] The drain outlet range is the range of the drain outlet set by the technician. When the dripping position falls into the drain outlet range, it means that the extension length does not need to be changed, so step S104 is continued.

[0051] The adjustment distance refers to the straight-line distance that needs to be adjusted when the water droplets fall into the drain outlet range. When the dripping position does not fall into the drain outlet range, it means that the extension length needs to be changed. Therefore, the straight-line distance of the intersection between the dripping position and the drain outlet range is calculated, and the minimum straight-line distance is used as the adjustment distance.

[0052] Step S205: When the adjustment distance is a positive value, the shielding inclination is updated according to the adjustment distance.

[0053] When the adjustment distance is a positive value, it indicates that the extended and covered range of the shielding device includes the drain outlet range. Therefore, the new extended end is calculated by adjusting the distance and the extended end, and the new shielding inclination is calculated by the Pythagorean theorem and trigonometric functions using the new extended end and the reference shielding position.

[0054] Step S206: When the adjustment distance is a negative value, updating the extension length according to the adjustment distance.

[0055] When the adjustment distance is a negative value, it means that the extended and covered range of the shielding device does not include the drain outlet range. Therefore, the new extended end is calculated by adjusting the distance and the extended end, and then the adjusted length is calculated by updating the extended ends before and after. The sum of the extended length and the adjusted length is calculated as the new extended length.

[0056] Reference Figure 3 , the preset detection methods include: Step S300: Acquire the detected wind direction, detected wind speed and image detection information of the extended end of the green energy-saving building.

[0057] The detected wind direction refers to the wind direction at the location of the green energy-saving building, and the detected wind speed refers to the wind speed at the location of the green energy-saving building. The wind direction detected by the ultrasonic wind speed and direction sensor preset on the green energy-saving building is used as the detected wind direction, and the detected wind speed is used as the detected wind speed. The image detection information is an image of the extended end taken by the camera, and the image detection information includes the range corresponding to the drip height.

[0058] Step S301: Determine the horizontal wind speed according to the detected wind direction and the detected wind speed.

[0059] The horizontal wind speed refers to the wind speed in the horizontal direction of the natural wind, and the horizontal wind speed is calculated by detecting the wind direction and the wind speed. The calculation method of the horizontal wind speed is common knowledge for those skilled in the art and will not be described in detail here.

[0060] Step S302: determining the shielding area according to the extension length.

[0061] The shielding width is the width of the curtain and steel curtain set by the technicians. The shielding area refers to the area of ​​the shielding device that shields rainwater. The shielding area is calculated by multiplying the extended length and the preset shielding width.

[0062] Step S303: Calculate the shielding flow rate according to the shielding inclination, precipitation and shielding area.

[0063] The shielding flow rate refers to the flow rate of rainwater on the shielding device. The product of the precipitation and the shielding area is calculated as the flow rate in the horizontal direction, and then the shielding inclination and the horizontal flow rate are used to calculate the shielding flow rate using trigonometric functions.

[0064] Step S304: updating the image detection information according to a preset unit time, and determining the initial drop velocity according to the image detection information before and after the update and the preset water drop feature.

[0065] The water droplet feature is the shape feature of the water droplet set by the technician. The unit time is the time length value set by the technician for detecting the speed of the water droplet falling. The initial drop velocity refers to the initial velocity of the water droplet when it falls from the extension end. The position of the water droplet is selected by the image detection information before updating, and the position of the selected water droplet is marked in the image detection information after updating. The interval distance between the two positions is calculated, and the quotient of the interval distance and the unit time is calculated as the initial drop velocity.

[0066] Step S305: Determine the estimated water drop volume according to the initial drop velocity.

[0067] The estimated water drop volume refers to the estimated volume of the water drop dripping from the extension end, and the estimated water drop volume is obtained by analyzing the initial drop velocity.

[0068] Step S306: Determine the horizontal wind force according to the estimated water drop volume and the horizontal wind speed.

[0069] Horizontal wind force refers to the force exerted by horizontal wind speed on water droplets of estimated water droplet volume. The estimated water droplet volume and horizontal wind speed are input into the preset wind database to match the horizontal wind force. The wind database contains the correspondence between the estimated water droplet volume, wind speed, wind force, wind power and wind distance. The wind database is set manually and will not be described in detail here.

[0070] Step S307: Calculate the offset distance according to the initial drop velocity, drop height, estimated drop volume and horizontal wind force.

[0071] The offset distance is calculated by the initial drop velocity, drop height, estimated drop volume and horizontal wind force. The offset distance is calculated as: X=V x × (2h / g) 0.5 +0.5×(F w ×h) / ρVg, X is the offset distance, V x is the initial drop velocity, F w is the horizontal wind force, V is the estimated water drop volume, h is the drop height, g is the gravitational acceleration, and ρ is the water density.

[0072] Reference Figure 4 , the methods for determining the adjustment distance include: Step S400: determining the target wind speed according to the adjustment distance.

[0073] The target wind speed refers to the maximum horizontal wind speed required to drop water droplets on the extended end into the drainage range. The adjusted wind force is obtained by calculating the adjusted distance as the offset distance, and the adjusted wind force is input into the blowing database to match the target wind speed.

[0074] Step S401: Calculate the difference between the horizontal wind speed and the target wind speed as the wind speed deviation value.

[0075] The wind speed deviation value refers to the deviation value between the horizontal wind speed and the target wind speed. The difference between the horizontal wind speed and the target wind speed is calculated as the wind speed deviation value.

[0076] Step S402: Determine the adjustment power according to the wind speed deviation value and the shielding inclination.

[0077] The adjusted power refers to the power of the blowing device. The adjusted wind speed is calculated using trigonometric functions based on the wind speed deviation value and the shielding inclination, and then the adjusted wind speed is input into the blowing database to match the adjusted power.

[0078] Step S403: When the adjusted power does not exceed the preset reference power, the blowing device preset on the shielding device is controlled to adjust the power for blowing.

[0079] The reference power is the maximum power that the blowing device can operate at set by the technician. When the adjusted power exceeds the reference power, it means that the blowing device is not easy to make the natural wind reach the target wind speed in the horizontal direction, so jump to step S200 to continue execution. When the adjusted power does not exceed the reference power, it means that the blowing device is easy to make the natural wind reach the target wind speed in the horizontal direction, so the blowing device is controlled to blow with the adjusted power.

[0080] Reference Figure 5 , methods for determining the estimated drop volume include: Step S500: Calculate the detection height according to the initial drop velocity.

[0081] The detection height refers to the height at which the number of water droplets falling from the extended end is detected, and the detection height is calculated by calculating the quotient of the initial drop velocity and the preset unit time.

[0082] Step S501: determining a detected water drop image according to the detection height, the drop height and the image detection information.

[0083] The detected water drop image refers to the image in the range corresponding to the detection height. The image between the total extended lengths is selected from the image detection information as the detected water drop image by symmetrically extending the center line of the drop height until the total extended length is consistent with the detection height.

[0084] Step S502: determining the number of detected water drops according to the detected water drop image and preset water drop features.

[0085] The number of detected water drops refers to the number of water drops dripping on the extended end in unit time, and the number of images corresponding to the water drop features are selected from the detected water drop image as the number of detected water drops.

[0086] Step S503: Calculate the estimated water drop volume according to the blocked flow rate and the number of marked water drops.

[0087] The estimated droplet volume is calculated by dividing the quotient of the blocked flow rate and the number of marked droplets.

[0088] Reference Figure 6 , the method after calculating the blocking flow also includes: Step S600: When the blocked flow exceeds the preset reference flow, the difference between the blocked flow and the preset reference flow is calculated as the flow deviation value.

[0089] The reference flow rate is the maximum flow rate of rainwater that the shielding device can withstand when water drops can be detected on the extension end set by the technician. When the shielding flow rate does not exceed the reference flow rate, it means that water drops are still falling at the extension end, so no adjustment is made.

[0090] The flow deviation value refers to the deviation between the blocked flow and the benchmark flow. When the blocked flow exceeds the benchmark flow, it means that there is a water curtain flowing to the drain outlet at the extended end. Therefore, the difference between the blocked flow and the benchmark flow is calculated as the flow deviation value.

[0091] Step S601: Determine the marked blowing power according to the flow deviation value and the shielding area.

[0092] The marked blowing power refers to the power of the marked blowing device for blowing. The marked blowing power is matched by inputting the flow deviation value and the shielding area into the preset blowing database. The blowing database also stores the marked blowing power corresponding to the deviation values ​​of different water flow rates and shielding areas, which will not be elaborated here.

[0093] Step S602: Determine the slowing blowing distance according to the extended end and the preset slowing position.

[0094] The mitigation position is the position where the shielding device set by the technician needs to lower the water flow. The mitigation position is generally set to the reference shielding position or the center position of the shielding device. The mitigation blowing distance refers to the distance required for the blowing device to blow to the mitigation position. The mitigation blowing distance is calculated by calculating the straight-line distance between the extended end and the mitigation position.

[0095] Step S603: updating the marked blowing power according to the reduced blowing distance, and controlling the marked blowing device preset on the shielding device to operate with the shielding inclination and the updated marked blowing power.

[0096] A new marked blowing power is matched by slowing down the blowing distance and inputting the marked blowing power into the blowing database, and the marked blowing device is controlled to operate with the shielding inclination and the updated marked blowing power.

[0097] Reference Figure 7 , the method before extending the occlusion with the extension length and the occlusion inclination includes: Step S700: Acquire the obstruction image information around the green energy-saving house building according to the detected wind direction.

[0098] The features of the obstruction are the shape and color of the obstruction such as buildings or trees set by the technicians. The obstruction image information refers to the image of the obstruction around the green energy-saving house facing the wind direction detection. The camera takes the surrounding image of the green energy-saving house in the relative direction of the wind direction detection, and selects the image corresponding to the obstruction feature from the surrounding image as the obstruction image information.

[0099] Step S701: determining the occlusion height, occlusion area and interval distance according to the occlusion image information.

[0100] The shielding height refers to the height of the shielding object, the shielding area refers to the area of ​​the shielding object, and the spacing distance refers to the distance between the shielding object and the green energy-saving house building.

[0101] The type of occlusion object and the coverage area of ​​the occlusion object in the image are identified through the occlusion image information, and then the type of occlusion object and the coverage area are input into a preset occlusion database to match the occlusion height and occlusion area.

[0102] The reference shielding height is the distance between the reference shielding position set by the technician and the ground. The reference mark height refers to the height of the shielding object that can shield the reference shielding height at the interval distance. The shielding database contains the correspondence between the shielding object type, coverage area, shielding height, shielding area and interval distance, and also contains the correspondence between the rain slope, interval distance, reference shielding height and reference mark height. The shielding database is set manually and will not be described here.

[0103] Step S702: Determine the reference mark height according to the rain slope, the interval distance and the preset reference shielding height.

[0104] The reference mark height is matched by inputting the rain slope, interval distance and reference shading height into the shading database.

[0105] Step S703: According to the occlusion height, a occlusion height exceeding the reference mark height is selected as the mark occlusion height, and the occlusion area of ​​the mark occlusion height is selected as the mark occlusion area.

[0106] The marked obstruction height refers to the obstruction height that exceeds the reference mark height under the corresponding interval distance. The marked obstruction area refers to the obstruction area of ​​the obstruction at the marked obstruction height. The corresponding interval distance is selected by the obstruction height, and the obstruction height that exceeds the reference mark height is used as the marked obstruction height, and the obstruction area of ​​the marked obstruction height is used as the marked obstruction area.

[0107] Step S704: determining a shielding position according to the marked shielding area and the rainwater inclination, and controlling a shielding device at the shielding position to extend and shield according to the extension length and shielding inclination.

[0108] The drainage range is the range between the drainage outlet and the green energy-saving housing building set by the technicians. The shielding position refers to the position of the shielding device that needs to be extended. The three-dimensional model is established through the preset building specifications of the green energy-saving housing building, and the building specifications are projected by the rainwater inclination. The projected range on the ground is used as the building shielding range, and then the marked shielding area is projected by the rainwater inclination. The projected range is used as the shielding range, and the intersection range is obtained through the building shielding range, the shielding range and the drainage range.

[0109] The maximum shielding area is matched by inputting the rainwater inclination into the shielding database, and the reference shielding position of the shielding device corresponding to the shielding area with the largest overlap with the intersection range is used as the shielding position. The shielding database also stores the maximum shielding area of ​​the shielding device corresponding to different rainwater inclinations, which will not be elaborated here.
