And S2, creating a unity scene, and importing the exported model file into the scene, wherein a sub-camera is arranged in the unity scene and used for observing a water network system model in the unity scene.
The step S2 specifically comprises the following steps: and creating a unity scene, and importing the exported model file into the unity scene. The sub-cameras are arranged on the unity, the sub-cameras are adjusted to proper default angles and view angles, the cameras can be freely moved to observe all water networks in the cell to form a model, the model does not need to be moved, but the change of the water networks in the cell needs to be reflected in the model through data of all devices.
The main logics of the water level changes of the water pool and the water tank in the water network system model are as follows:
the water level detector is bound to corresponding pool and water tank models, data transmitted in real time are used as model fixed point data, a shader type is set in Tags of the SubShader to be an opaque shader, a CG grammar compiling starting identifier CGPROGRAM is used in a rendering channel of the SubShader, a vertex shader entry function vert and a fragment shader entry function frag are declared, an external library UnityCG. A structure v2f is defined for transferring data from the vertex shader to the fragment shader, and the vertex shader v2fvert will be implemented below, with the parameter appdata. Calling method unitobjecttoclippos () first enters the coordinate position of water in the parameter appdata, and calls UNITY _ TRANSFER _ FOG to convert the coordinate. Then, world coordinates are obtained, the liquid height is controlled to change, the structure body v2f is returned, then, the color of a wire frame needs to be rendered, an inlet function fixed4frag of the fragment shader is realized, the parameter is a structure body variable v2fi, and the output semantic of the function is set as SV _ Target (the semantic used for outputting the color of the fragment shader function is more than DX 10). And calculating the liquid level line of the liquid in the water tank, realizing line color matching through a step function, and sending an alarm to a manager for informing the manager of the alarm of a pool or a well higher than the alarm line, or setting a linkage to reach the alarm line to start the drainage pump. And then, the step function is also used for the liquid surface liquid to realize color matching.
To be supplemented, in the present embodiment: the data that each water pump of district afferent directly demonstrate on the water pump model that corresponds, acquiesce only to show water pressure and operating condition, and after the user clicked the water pump alone, the camera removed to water pump the place ahead, and the detailed data of showing the water pump is shown to the detailed model, show water pump detailed data, like water pump position, model, parameter, live time etc..
In order to show the detailed data of each model, a UIcanvas needs to be created in the unity, a UI component is added to the UIcanvas, and the detailed running data and static data of each model can be displayed through a Text component. Creating a unity script, inheriting a Monobehaviour class, acquiring a corresponding component by a GetComponent < render > (), setting a variable receiving component, and sending application data to a shader by a variable material.
Further: the other models are also operated in the same flow, and the models of the buildings are only subjected to translucency treatment, so that managers can visually see the arrangement of the water networks of all floors conveniently. And (3) displaying the water flow direction of the water network model of the community, starting a pressurizing pump to pressurize when the water pressure of each layer of water pipe reaches a set threshold value, but not pressurizing when the water pressure of the high layer of water pipe is insufficient. Meanwhile, the water pressures of the water pipes in different sections are compared, whether the water pipe leakage condition exists or not is judged, the water pipe section with the problem is marked, and an alarm is sent to prompt a manager. For each water pump, an administrator can click the designated water pump to carry out switch operation, and can also carry out automatic treatment by configuring a contextual mode, such as timely warning the administrator when an error or an abnormality occurs.
The working principle and the purpose are as follows: in order to solve the defects of the existing water supply and drainage system, a digital twin-based visual scheme of a community water supply and drainage system is provided, 3D visual operation is carried out on water supply and drainage distribution in a community, the community water supply and drainage can be clear at a glance, and meanwhile, the working condition of equipment is detected in real time by combining a water level detector, a water pressure detector, a booster pump, a submersible pump, a sewage pump, a water pool, a water tank and other internet-of-things equipment, and the condition which possibly occurs is alarmed. When rainstorm occurs, when a large amount of accumulated water appears in the elevator shaft, an alarm is given in time, and community managers can handle the alarm in time.
The data that acquires through the water level detector of each bilge well, wastewater well, elevartor shaft, adjust in real time to the 3D effect of water level, can very audio-visual change of seeing the water level to let the managers efficient make the decision whether long-range water pump of opening carries out the drainage, also can set up the water level threshold value of safe drainage, let district drainage system can more efficient operation, increase district drainage throughput.
Through the data that a large amount of water pressure detectors obtained in the inside water supply network of district and the drainage network, carry out the visual display of 3D to the water pressure of district water network pipeline in real time, let managers can easily know the pressure variation between each pipeline, come the backward flow pollution problem that the early warning probably appears through pressure variation. Meanwhile, the water supply pressurization operation of the pressurization pump room can be adjusted according to the real-time 3D visually displayed high-rise water supply pressure condition, so that the electric quantity is saved.
Of course, in order to reduce the requirements of 3D visualization on the performance of the computer, the display effects of the water level of the water pool, the water pressure of each water pump and the water flow direction are changed in real time, other models which are set in advance are used, and the real-time operation of each device is also operated through the selected and displayed interface. Each detection device carries out alarm prompt by changing the color of the model and flashing, and displays alarm content, so that a manager can quickly and accurately know the alarm position and specific alarm information.
The foregoing description has described specific embodiments of the present invention. It is to be understood that the present invention is not limited to the specific embodiments described above, and that various changes or modifications may be made by one skilled in the art within the scope of the appended claims without departing from the spirit of the invention.
