如何使用thingjs制作智慧粮仓可视化项目？物联网可视化项目如何制作？制作好的物联网场景该怎么去开发？

在制作项目的时候，能不能做是一个问题，怎么去做又是一个问题，交付项目的时候能否让用户满意？能否在规定时间保质保量的交付项目，而三维可视化项目的制作，相比于普通项目来说更让人头大，它要有场景模型，还得有一定的交互功能，比如摄像机视角移动或者是跟随某个物体移动，同时还得采集数据，还得使用数据采集器(传感器),收集到数据并上传到数据库中，然后3D开发人员还得获取到这个数据，并且将有需要的数据处理成可以看见的图表或者是云图等等，总体来说，一个完整需求的三维可视化开发难度还是比较大的，这里，分享一个智慧粮仓的可视化解决方案。

本次要分享的ThingJS公开的可视化解决方案是“智慧粮仓”。

如何制作这个解决方案的呢？

第一步：搭建场景；

第二步：开发场景；

第三步：数据对接；

第四步：发布项目；

场景的搭建，通过3Dmax搭建相关特殊模型，通过3dmax上传插件上传到ThingJS的campusbuilder中，通过thingjs的campusbuilder园区搭建工具制作粮仓场景；

开发场景，第一点就是控制摄像机的视角，thingjs的视角也是camera摄像机来控制的，要开发项目，首先就是学会使用camera，然后才是各种功能，智慧粮仓中有着通栏，里面含有编号、温湿度、云图、能耗、视频、人车定位这几个功能，这些功能均在thingjs在线开发左侧的官方示例。

本次分享的智慧粮仓可视化解决方案中的数据都是写死的数据，可自行使用JavaScript语法，通过thingjs官方示例中的数据对接方式，获取数据并且放入到对于图表中。以下是四种数据对接中的ajax对接方式。

/**
 * 说明：
 * 通过CORS解决跨域问题
 * 并将数据挂接到物体（car01）身上，与panel面板进行数据绑定
 * 当温度>25℃时 car01变红
 * 教程：ThingJS教程——>数据对接——>Ajax对接
 * 难度：★★☆☆☆
 */
var app = new THING.App({
    url: 'https://www.thingjs.com/static/models/storehouse'
});

// 定时器
var timer;

app.on('load', function () {
    var car = app.query('car01')[0];

    // 物体身上创建monitorData对象 用于存储动态监控数据
    car.monitorData = {
        '温度': ''
    };

    updateData(car);
    createPanel(car);
})

/** ******************* 以下为ajax数据对接 ********************/
// 服务器程序端 通过设置 Access-Control-Allow-Origin 解决跨域问题
// 更多关于 CORS "跨域资源共享"（Cross-origin resource sharing）的技术细节 请自行搜索
// 请求传入参数为 { "id": id }
// 服务器返回的数据格式为 {"state":"success","data":{"id":"4967","temper":"15℃","humi":"59%","power":"20kWh"}}

function updateData(obj) {
    // 如果网站是 https 接口则对应 https 请求
    // 如果网站是 http 接口则对应 http 请求即可
    $.ajax({
        type: "get",
        url: "https://3dmmd.cn/getMonitorDataById",
        data: { "id": obj.id },
        dataType: "json", // 返回的数据类型 json
        success: function (d) {
            console.log(d);
            var temper = d.data.temper;

            // 设置物体身上的监控数据
            obj.setAttribute("monitorData/温度", temper);

            changeColor(obj);

            // 每隔3s 请求一次数据
            timer = setTimeout(function () {
                updateData(obj)
            }, 3000);
        }
    });
}

// 停止请求数据
function stopUpdate() {
    clearTimeout(timer);
}

function createPanel(obj) {
    // 界面组件
    var panel = new THING.widget.Panel({
        titleText: 'car01温度',
        hasTitle: true
    });

    var monitorControl = panel.addBoolean({ 'isOpen': true }, "isOpen").caption("监控开关");
    // 将物体的monitor对象中的数据 与 panel 进行绑定
    panel.add(obj.monitorData, '温度').name('温度');

    monitorControl.on('change', function (ev) {
        if (ev) {
            updateData(obj);
        }
        else {
            stopUpdate();
        }
    })
}

// 如果温度>25 改变颜色
function changeColor(obj) {
    var temper = obj.getAttribute("monitorData/温度");
    var value = temper.substr(0, temper.indexOf("℃"));
    if (value > 25) {
        obj.style.color = 'rgb(255,0,0)';
    }
    else {
        obj.style.color = null;
    }
}

开发场景需要通过thingjs的app对象引入我们搭建的园区场景：

//-----------------------------------------------------------------------------
// 应用入口
var toolBarState = true;
var startFps = false;
var fpsControl = null;

var app = new THING.App({
   container: "div3d",
    skyBox: 'BlueSky',
    url: "models/silohouse",
    ak: "app_test_key",
    sucess: function () {
        app.camera.position = [98.5, 176.3, 218.5];
        app.camera.target = [19.7, -47.8, -22.5];
    }
});

其余的就是添加页面元素以及通过URL的方式将模型加载到在线开发中，制作出对应的tab表格，完整的智慧粮仓代码如下：
