第十四章:设备与模板排布系统
14.1 设备系统概述
14.1.1 场布设备的概念
在建筑工程场地布置中,施工设备的合理布置是确保施工安全和效率的关键因素。FY_Layout提供了完整的设备元素系统(LayoutEquipment),用于管理和布置各类施工设备,如塔吊、升降机、搅拌站等。
14.1.2 设备元素类型定义
在LayoutElementType.cs中,设备元素的类型定义如下:
public static ElementType LayoutEquipment = new ElementType
{
Guid = Guid.ParseExact("{552E316C-ADB2-43A7-AC77-9E0069ACEDC8}", "B").ToLcGuid(),
Name = "LayoutEquipment",
DispalyName = "场布设备",
ClassType = typeof(QdLayoutEquipment)
};
14.1.3 设备系统的核心特点
- 参数化设计:设备的尺寸、旋转角度、安装位置等均可参数化调整
- 类型丰富:支持各类常见施工设备的定义和布置
- 三维可视化:设备在三维视图中有对应的立体展示
- 碰撞检测:可与其他场布元素进行空间冲突检查
14.2 QdLayoutEquipment类详解
14.2.1 类结构
public class QdLayoutEquipment : DirectComponent
{
// 设备类型名称
public string EquipmentName
{
get { return Properties.GetValue<string>("EquipmentName"); }
set { SetProps((GetPropId(nameof(EquipmentName)), value)); }
}
// 底部高程
public double Bottom
{
get { return Properties.GetValue<double>("Bottom"); }
set { SetProps((GetPropId(nameof(Bottom)), value)); }
}
// 材质信息
public MaterialInfo Material
{
get { return Properties.GetValue<MaterialInfo>("Material"); }
set { SetProps((GetPropId(nameof(Material)), value)); }
}
// 设备轮廓
public Polyline2d Outline
{
get { return this.BaseCurve as Polyline2d; }
set { this.BaseCurve = value; }
}
// 旋转角度
public double Rotation
{
get { return Properties.GetValue<double>("Rotation"); }
set { SetProps((GetPropId(nameof(Rotation)), value)); }
}
public QdLayoutEquipment(LcComponentDefinition def) : base(def)
{
Type = LayoutElementType.LayoutEquipment;
}
public override Box2 GetBoundingBox()
{
return new Box2().ExpandByPoints(
GetShapes()[0].Curve2ds
.SelectMany(n => n.GetPoints()).ToArray());
}
public override LcElement Clone()
{
var clone = new QdLayoutEquipment(this.Definition);
clone.Copy(this);
return clone;
}
public override void Copy(LcElement src)
{
base.Copy(src);
var equip = (QdLayoutEquipment)src;
}
}
14.2.2 设备属性体系
设备元素支持以下核心属性:
| 属性名 | 类型 | 说明 | 默认值 |
|---|---|---|---|
| EquipmentName | string | 设备名称 | ”” |
| Bottom | double | 底部高程(mm) | 0 |
| Material | MaterialInfo | 设备材质 | Metal1 |
| Rotation | double | 旋转角度(弧度) | 0 |
| Outline | Polyline2d | 设备轮廓 | 空多段线 |
14.3 模板排布系统
14.3.1 TemplateArrange功能概述
TemplateArrange是FY_Layout中的模板排布模块,位于QdLayout/TemplateArrange/目录下。该模块实现了基于用地红线的自动排布功能,可以根据预定义的模板,在指定的区域内自动排列场布元素。
14.3.2 核心类:TemComAttriAction
public class TemComAttriAction : DirectComponentAction
{
public TemComAttriAction() { }
public TemComAttriAction(IDocumentEditor docEditor) : base(docEditor)
{
commandCtrl.WriteInfo("命令:模板排布");
}
// 执行模板排布
public async void ExecCreate(string[] args = null)
{
// 1. 选择用地红线
var elementInputer = new ElementSetInputer(this.docEditor);
var result = await elementInputer.Execute("请选择用地红线:");
if (elementInputer.isCancelled || result == null)
{
this.Cancel();
return;
}
// 2. 获取红线区域
if (result.ValueX != null)
{
var eles = result.ValueX as List<LcElement>;
// 解析红线元素,获取排布区域
ProcessRedLines(eles);
}
}
// 处理红线元素
private void ProcessRedLines(List<LcElement> elements)
{
// 提取红线轮廓
// 计算可排布区域
// 执行自动排布算法
}
}
14.3.3 命令注册
模板排布的命令在LayoutCmds.cs中注册:
[CommandMethod(Name = "SelRedLinesForArrange", ShortCuts = "SRFA")]
public CommandResult SelRedLinesForArrange(
IDocumentEditor docEditor, string[] args)
{
TemComAttriAction tcaRt = new TemComAttriAction(docEditor);
tcaRt.ExecCreate(args);
return CommandResult.Succ();
}
14.4 绘制与调整系统(DrawOrAdjust)
14.4.1 DrawOrAdjustAction概述
FY_Layout提供了DrawOrAdjustAction类,用于在场布设计中进行元素的绘制或位置调整操作:
[CommandMethod(Name = "DrawOrAdjust", ShortCuts = "DRAD")]
public CommandResult DrawOrAdjust(
IDocumentEditor docEditor, string[] args)
{
DrawOrAdjustAction drad = new DrawOrAdjustAction(docEditor);
drad.ExecCreate(args);
return CommandResult.Succ();
}
14.4.2 DrawOrAdjustAction类
public class DrawOrAdjustAction : DirectComponentAction
{
public DrawOrAdjustAction() { }
public DrawOrAdjustAction(IDocumentEditor docEditor) : base(docEditor)
{
commandCtrl.WriteInfo("命令:绘制或调整");
}
public async void ExecCreate(string[] args = null)
{
// 1. 提示用户选择操作模式
// 2. 如果选择绘制,进入绘制流程
// 3. 如果选择调整,进入调整流程
// - 选择已有元素
// - 修改位置/尺寸/属性
// - 更新显示
}
}
14.5 开门边线系统(OpenLine)
14.5.1 QdOpenLine元素
开门边线(OpenLine)用于标记围墙或围挡的出入口位置:
public static ElementType OpenLine = new ElementType
{
Guid = Guid.ParseExact("{6FE950F0-9E13-FA8A-E216-AAE0D40BECBC}", "B").ToLcGuid(),
Name = "OpenLine",
DispalyName = "开门边线",
ClassType = typeof(QdOpenLine)
};
14.5.2 OpenLineAction操作类
public class OpenLineAction : DirectComponentAction
{
public OpenLineAction() { }
public OpenLineAction(IDocumentEditor docEditor) : base(docEditor)
{
commandCtrl.WriteInfo("命令:OpenOuterLine");
}
// 创建开门边线
public async void ExecCreateOpenLine(string[] args = null)
{
// 1. 获取用户指定的起点和终点
// 2. 在围墙或围挡上创建开口标记
// 3. 设置开口宽度和方向
}
}
14.5.3 命令注册
[CommandMethod(Name = "OpenOuterLine", ShortCuts = "OPL")]
public CommandResult OpenOuterLine(
IDocumentEditor docEditor, string[] args)
{
var tcaRt = new OpenLineAction(docEditor);
tcaRt.ExecCreateOpenLine(args);
return CommandResult.Succ();
}
14.6 设备布置实战流程
14.6.1 典型的设备布置工作流
- 确定场地范围:使用Site命令绘制场地边界
- 绘制用地红线:使用PropertyLine命令标注用地范围
- 布置主体设施:使用PlanBuild命令绘制拟建建筑
- 布置施工道路:使用Road/Berm命令规划道路网络
- 布置施工设备:在合适位置放置设备元素
- 自动排布优化:使用SelRedLinesForArrange命令进行自动排布
- 调整和优化:使用DrawOrAdjust命令微调元素位置
14.6.2 设备间距规范
在施工场地布置中,设备的间距需要满足安全规范:
| 设备类型 | 最小间距(m) | 安全距离(m) | 说明 |
|---|---|---|---|
| 塔吊 | 2.0 | 5.0 | 吊臂旋转半径外 |
| 升降机 | 1.5 | 3.0 | 围护结构外 |
| 搅拌站 | 3.0 | 5.0 | 操作空间需求 |
| 配电箱 | 1.0 | 2.0 | 安全操作距离 |
14.6.3 设备与其他元素的关系

14.7 属性面板与参数编辑
14.7.1 设备属性面板
设备元素的属性通过PropertyObserver暴露到属性面板:
public override List<PropertyObserver> GetPropertyObservers()
{
return new List<PropertyObserver>()
{
new PropertyObserver()
{
Name = "EquipmentName",
DisplayName = "设备名称",
CategoryName = "Basic",
CategoryDisplayName = "基本信息",
PropType = PropertyType.String,
Getter = (ele) => (ele as QdLayoutEquipment)
.Properties.GetValue<string>("EquipmentName"),
Setter = (ele, value) =>
{
var equip = ele as QdLayoutEquipment;
equip.OnPropertyChangedBefore("EquipmentName",
equip.EquipmentName, value);
equip.Properties.SetValue("EquipmentName",
value.ToString());
equip.OnPropertyChangedAfter("EquipmentName",
equip.EquipmentName, value);
}
},
new PropertyObserver()
{
Name = "Bottom",
DisplayName = "底高",
CategoryName = "Geometry",
CategoryDisplayName = "几何信息",
PropType = PropertyType.Double,
Getter = (ele) => (ele as QdLayoutEquipment)
.Properties.GetValue<double>("Bottom"),
Setter = (ele, value) =>
{
var equip = ele as QdLayoutEquipment;
if (!double.TryParse(value.ToString(), out var bottom))
return;
equip.OnPropertyChangedBefore("Bottom",
equip.Bottom, bottom);
equip.Properties.SetValue("Bottom", bottom);
equip.ResetCache();
equip.OnPropertyChangedAfter("Bottom",
equip.Bottom, bottom);
}
},
new PropertyObserver()
{
Name = "Rotation",
DisplayName = "旋转角度",
CategoryName = "Geometry",
CategoryDisplayName = "几何信息",
PropType = PropertyType.Double,
Getter = (ele) => (ele as QdLayoutEquipment)
.Properties.GetValue<double>("Rotation"),
Setter = (ele, value) =>
{
var equip = ele as QdLayoutEquipment;
if (!double.TryParse(value.ToString(), out var rotation))
return;
equip.OnPropertyChangedBefore("Rotation",
equip.Rotation, rotation);
equip.Properties.SetValue("Rotation", rotation);
equip.ResetCache();
equip.OnPropertyChangedAfter("Rotation",
equip.Rotation, rotation);
}
}
};
}
14.7.2 属性变更通知机制
FY_Layout的属性变更采用Before/After通知模式:
// 变更前通知 - 用于记录历史状态(撤销/重做)
equip.OnPropertyChangedBefore("PropertyName", oldValue, newValue);
// 执行属性变更
equip.Properties.SetValue("PropertyName", newValue);
// 重置缓存 - 更新几何数据和包围盒
equip.ResetCache();
// 变更后通知 - 用于触发视图更新
equip.OnPropertyChangedAfter("PropertyName", oldValue, newValue);
14.8 UI工具栏中的设备按钮
14.8.1 LayoutPlugin中的设备按钮注册
在LayoutPlugin.cs中,设备和模板相关按钮被注册到场布工具栏:
public static TabItem LayoutItem = new TabItem
{
Name = "LayoutMajor",
Text = "场布",
ShortCut = "",
Children = new TabButtonGroup[]
{
// ... 其他按钮组 ...
new TabButtonGroup
{
Name = "设备",
Children = new TabButton[]
{
new TabButton
{
Name = "场布设备",
CommandName = "LayoutEquipment",
Image = Resources.equipment_icon,
ToolTip = "放置施工设备"
}
}
},
new TabButtonGroup
{
Name = "排布",
Children = new TabButton[]
{
new TabButton
{
Name = "模板排布",
CommandName = "SelRedLinesForArrange",
Image = Resources.arrange_icon,
ToolTip = "基于红线自动排布"
},
new TabButton
{
Name = "绘制调整",
CommandName = "DrawOrAdjust",
Image = Resources.adjust_icon,
ToolTip = "绘制或调整元素位置"
}
}
}
}
};
14.9 扩展开发:自定义设备类型
14.9.1 创建塔吊设备示例
// 1. 定义塔吊元素类
public class QdTowerCrane : QdLayoutEquipment
{
// 吊臂长度
public double ArmLength
{
get { return Properties.GetValue<double>("ArmLength"); }
set { SetProps((GetPropId(nameof(ArmLength)), value)); }
}
// 吊臂高度
public double ArmHeight
{
get { return Properties.GetValue<double>("ArmHeight"); }
set { SetProps((GetPropId(nameof(ArmHeight)), value)); }
}
// 额定起重量
public double MaxLoad
{
get { return Properties.GetValue<double>("MaxLoad"); }
set { SetProps((GetPropId(nameof(MaxLoad)), value)); }
}
public QdTowerCrane(LcComponentDefinition def) : base(def)
{
EquipmentName = "塔吊";
ArmLength = 50000; // 50m
ArmHeight = 80000; // 80m
MaxLoad = 8000; // 8t
}
}
// 2. 实现塔吊操作类
public class TowerCraneAction : DirectComponentAction
{
public TowerCraneAction() { }
public TowerCraneAction(IDocumentEditor docEditor) : base(docEditor)
{
commandCtrl.WriteInfo("命令:放置塔吊");
}
public async void ExecCreate(string[] args = null)
{
// 1. 获取放置点
var pointInputer = new PointInputer(docEditor);
var result = await pointInputer.Execute("指定塔吊中心位置:");
if (pointInputer.isCancelled || result == null)
{
this.Cancel();
return;
}
// 2. 创建塔吊元素
var center = result.Value;
CreateTowerCrane(center);
}
private void CreateTowerCrane(Vector2 center)
{
var doc = docRt.Document;
var def = docRt.GetUseComDef(
$"{NamespaceKey}.施工设备", "塔吊", null);
var crane = new QdTowerCrane(def);
crane.Initilize(doc);
// 创建塔吊基座轮廓(正方形)
var baseSize = 3000; // 3m基座
var outline = new Polyline2d();
outline.Curve2ds.Add(new Line2d(
new Vector2(center.X - baseSize/2, center.Y - baseSize/2),
new Vector2(center.X + baseSize/2, center.Y - baseSize/2)));
outline.Curve2ds.Add(new Line2d(
new Vector2(center.X + baseSize/2, center.Y - baseSize/2),
new Vector2(center.X + baseSize/2, center.Y + baseSize/2)));
outline.Curve2ds.Add(new Line2d(
new Vector2(center.X + baseSize/2, center.Y + baseSize/2),
new Vector2(center.X - baseSize/2, center.Y + baseSize/2)));
outline.Curve2ds.Add(new Line2d(
new Vector2(center.X - baseSize/2, center.Y + baseSize/2),
new Vector2(center.X - baseSize/2, center.Y - baseSize/2)));
crane.Outline = outline;
crane.ResetBoundingBox();
crane.Layer = GetLayer().Name;
crane.Material = MaterialManager.GetMaterial(
MaterialManager.Metal1Uuid);
vportRt.ActiveElementSet.InsertElement(crane);
docRt.Action.ClearSelects();
}
private LcLayer GetLayer()
{
var layer = docRt.Document.Layers
.FirstOrDefault(n => n.Name == "Layout_Equipment");
if (layer == null)
{
layer = docRt.Document.CreateObject<LcLayer>();
layer.Name = "Layout_Equipment";
layer.Color = 0xFF6600;
layer.SetLineType(new LcLineType("ByLayer"));
layer.Transparency = 0;
docRt.Document.Layers.Add(layer);
}
return layer;
}
}
// 3. 实现塔吊三维显示
public class TowerCrane3dAction : IElement3dAction
{
public Object3D Get3dObject(LcElement element, DocumentRuntime docRt)
{
var crane = element as QdTowerCrane;
var group = new Group();
// 塔身(圆柱体)
var bodyGeometry = new CylinderGeometry(
500, 500, crane.ArmHeight, 8);
var bodyMaterial = new MeshPhongMaterial
{
Color = new Color(0xFF6600)
};
var body = new Mesh(bodyGeometry, bodyMaterial);
body.Position.Set(0, 0, crane.ArmHeight / 2);
group.Add(body);
// 吊臂(长方体)
var armGeometry = new BoxGeometry(
crane.ArmLength, 500, 500);
var armMaterial = new MeshPhongMaterial
{
Color = new Color(0xFFCC00)
};
var arm = new Mesh(armGeometry, armMaterial);
arm.Position.Set(0, 0, crane.ArmHeight);
group.Add(arm);
return group;
}
}
