1、千寻平台简介：
依托北斗地基增强基站提供定位服务，根据精度不同分为：亚米级、厘米级、静态毫米级的位置监控，自己有一套后台原始数据系统，并对初始数据进行处理，形成新的服务，称之FindS（云踪）、FindS等等，同时支持开发平台有Android、IOS、Linux嵌入式、Web API。
2、如何开始
a) 首先需要注册千寻的账号，有试用期，实名认证试用期会长一些。
b) 购买或者试用对应的服务
c) 激活服务实例
d) 获取对应的appkey 和 appScrete， 或者 sik和sis 接入千寻平台需要的
e) 下载千寻的开发的demo
3、 下面以千寻云踪FindS的WEB开发为例
Step1 : 进入千寻官网：https://www.qxwz.com/
Step2:注册或登录
Step3:跳过注册部分直接登录
Step 4：获取 sik 和sis
Step5:了解一下API概述
Step6:下载demo
Step7.这是开发就可以参考手册
实体管理：创建一个实体对象
位置管理：GPS位置相关数据
配置管理：主要是抽稀配置（也就是去掉部分数据换取性能）地理围栏配置（是否支持地理围栏）
事件管理：终端事件发生，例如共享单车的急刹车，急转弯
行程管理：骑行的过程，从开始到结束
地理围栏：划分一个GPS地理区域
规则引擎：配合规则引擎和消息通道使用，触发地理围栏需要自动做一些事情
消息通道：支持阿里云MNS
关系管理：将规则引擎和地理围栏与对应实体进行相应的关联
统计报表：统计一段时间内关于实体的相关的属性
3、 开发的代码：
