基于WebGL架构的3D可视化平台—三维设备管理(ThingJS实现楼宇设备管理3D可视化)

国内高层建筑不断兴建,它的特点是高度高、层数多、体量大。面积可达几万平方米到几十万平方米。这些建筑都是一个个庞然大物,高高的耸立在地面上,这是它的外观,而随之带来的内部的建筑设备也是大量的。为了提高设备利用率,合理地使用能源,加强对建筑设备状态的监视等,自然地就提出了楼宇自动化控制系统。下面我们将用ThingJS平台来模拟一个设备管理系统。

第一步,利用CampusBuilder搭建模拟场景。CampusBuilder的模型库有各种各样的模型,使我们搭建出的场景更逼真。使用CampusBuilde创建层级,之后再给层级加外立面就出现了当前的效果。详情移步:CampusBuilder3D场景制作工具

第二步,创建Equipment类,这里创建。switchControl方法主要一个完成一个计时器的功能来模拟设备警报。

class Equipment extends THING.Thing {
    constructor(app, name, obj, url) {
        super(app);
        this.name = name;
        this.obj = obj;
        this.url = url;
        this.interval = null;
        this.localPosition = [Math.floor(Math.random() * 7), 2.9, Math.floor(Math.random() * 7)];
    }
    createSelf() {
        app.create({
            type: 'Equipment',
            name: this.name,
            url: this.url,
            parent: this.obj,
            localPosition: this.localPosition,
            angle: 0
        });
    }
    switchControl(ev) {
        var flag;
        var equipment = app.query(this.name)[0];
        app.level.change(equipment);
        if (ev) {
            this.interval = setInterval(function () {
                if (flag) {
                    equipment.style.color = '#FF0000';
                    flag = false;
                } else {
                    flag = true;
                    equipment.style.color = '';
                }
            }, 500);
            console.log(this.interval + "查看是否创建了定时器");
        } else {
            console.log(this.interval);
            clearInterval(this.interval);
            if (equipment.style.color == '#FF0000')
                equipment.style.color = '';
        }
    }
}
THING.factory.registerClass('Equipment', Equipment);

  第三步,创建摄像机面板,烟感报警面板以及控制设备的开关,这里简单调整一下面板位置之后会增加两个创建设备的按钮。

//创建主面板
var panel1 = new THING.widget.Panel({
    titleText: '摄像机列表',
    closeIcon: false, // 是否有关闭按钮
    dragable: true,
    retractable: true,
    opacity: 0.9,
    hasTitle: true,
});
panel1.position = [80, 0];

var panel2 = new THING.widget.Panel({
    titleText: '烟感报警列表',
    closeIcon: false, // 是否有关闭按钮
    dragable: true,
    retractable: true,
    opacity: 0.9,
    hasTitle: true,
});
panel2.position = [80, 320];

// 创建任意对象
var dataObj1 = {
    open1: false,
    open2: false,
    open3: false,
    open4: false,
}
var dataObj2 = {
    open5: false,
    open6: false,
    open7: false,
    open8: false,
};

// 动态绑定物体
var open1 = panel1.addBoolean(dataObj1, 'open1').caption('设备01');
var open2 = panel1.addBoolean(dataObj1, 'open2').caption('设备02');
var open3 = panel1.addBoolean(dataObj1, 'open3').caption('设备03');
var open4 = panel1.addBoolean(dataObj1, 'open4').caption('设备04');
var open5 = panel2.addBoolean(dataObj2, 'open5').caption('设备01');
var open6 = panel2.addBoolean(dataObj2, 'open6').caption('设备02');
var open7 = panel2.addBoolean(dataObj2, 'open7').caption('设备03');
var open8 = panel2.addBoolean(dataObj2, 'open8').caption('设备04');

  第四步,开启场景层级切换,创建摄像机和烟感报警器各四个,创建一个数字标识index和保存equipment对象的数组equipmentGroup。

//创建equipment对象数组,以及数组标识
var equipmentGroup = [];
var index = 0;

app.on('load', function (ev) {

    app.level.change(ev.campus);

    for (var i = 0; i < 8; i++) {
        var type = null;
        if (i < 4) {
            type = 'http://model.3dmomoda.cn/models/62A8A75C75044E6AB3D8463FA0CB67AF/0/gltf/';
        } else {
            type = 'http://model.3dmomoda.cn/models/641A9B800DE5431E8C84DC290F8EFDE6/0/gltf/';
        }
        var equipment = new Equipment(app, 'equipment' + index++, app.query('floor' + (Math.floor(Math.random() * 5) + 1))[0], type);
        equipment.createSelf();
        equipmentGroup.push(equipment);
    }
});

  第五步,为每个设备对应的创建控制开关。

open1.on('change', function (ev) {
        equipmentGroup[0].switchControl(ev);
    });
    open2.on('change', function (ev) {
        equipmentGroup[1].switchControl(ev);
    });
    open3.on('change', function (ev) {
        equipmentGroup[2].switchControl(ev);
    });
    open4.on('change', function (ev) {
        equipmentGroup[3].switchControl(ev);
    });
    open5.on('change', function (ev) {
        equipmentGroup[4].switchControl(ev);
    });
    open6.on('change', function (ev) {
        equipmentGroup[5].switchControl(ev);
    });
    open7.on('change', function (ev) {
        equipmentGroup[6].switchControl(ev);
    });
    open8.on('change', function (ev) {
        equipmentGroup[7].switchControl(ev);
    });

  最后一步,创建两个按钮来控制创建设备。

new THING.widget.Button('创建烟感报警', function () {
    var type = 'http://model.3dmomoda.cn/models/641A9B800DE5431E8C84DC290F8EFDE6/0/gltf/';
    var equipment = new Equipment(app, 'equipment' + index++, app.query('floor' + (Math.floor(Math.random() * 5) + 1))[0], type,);
    equipment.createSelf();
    equipmentGroup.push(equipment);
    app.level.change(app.query(equipment.name)[0]);
});

new THING.widget.Button('创建摄像头', function () {
    var type = 'http://model.3dmomoda.cn/models/62A8A75C75044E6AB3D8463FA0CB67AF/0/gltf/';
    var equipment = new Equipment(app, 'equipment' + index++, app.query('floor' + (Math.floor(Math.random() * 5) + 1))[0], type,);
    equipment.createSelf();
    equipmentGroup.push(equipment);
    app.level.change(app.query(equipment.name)[0]);
});

  

在编写过程还是走了不少弯路的,最主要的就是计时器的卸载问题,最初的版本写来写去发现不能控制警报的关闭,后来才 发现计时器没有卸载,警报不但不会关闭而且闪动的频率越来越快。更改之后创建了Equipment这个类来控制所有设备,通过创建这个类的对象给他赋id,父物体,模型地址。这里控制器在开关被触发的时候创建一个新的计时器并赋给的这个对象,再次触发时清除这个计时器,警报的动画就关闭了。演示地址

/**

var app = new THING.App({
    url: "http://www.thingjs.com/./uploads/wechat/oLX7p05lsWJZUIxnIWsNXAzJ40X8/scene/CampusBuilder20181126134710",    // 场景地址
    "skyBox": "BlueSky"
});

//创建主面板
var panel1 = new THING.widget.Panel({
    titleText: '设备列表',
    closeIcon: false, // 是否有关闭按钮
    dragable: true,
    retractable: true,
    opacity: 0.9,
    hasTitle: true,
    titleImage: 'https://www.thingjs.com/static/images/example/icon.png'
});
panel1.position = [80, 0];

var panel2 = new THING.widget.Panel({
    titleText: '设备列表',
    closeIcon: false, // 是否有关闭按钮
    dragable: true,
