 有益效果

 附图说明

图2是本发明的红外接收电路的原理图。
 本发明的实施方式
实施例1
传统的建筑检测平衡的方法主要是在建筑施工阶段进行平衡检测，受施工现场限制严重，经纬仪正交垂直投点标定法很难顺利实施，使用免棱镜全站仪进行建筑物平衡检测也存在检测点位难以确定的问题。同时因为这些观测方法需要在比建筑物更高的观测位点实施，而现今我国建筑物越来越高，在施工阶段就难以实施，建成后也不会再进行检测。本发明通过检测周围环境温度来判断建筑平衡，当周围环境温度一致时建筑处于平衡状态，当周围环境出现温差，就说明建筑出现沉降。
在该实施例中，如图1所示，一种基于混沌保密的物联网商品信息防追溯系统，包括水平定位单元、温度检测单元、平衡观测单元和信号发射单元；
水平定位单元，确定温度检测单元的红外接收器处于同一水平位置；

平衡观测单元，通过判断温度检测单元检测的周围环境温度是否存在温差来判断当前建筑平衡状态；
网络传输单元，与网络连接，每天更新平衡观测结果，并发送到云端记录。
在进一步的实施例中，将所述温度检测单元的红外接收器安装在建筑物的外墙上，用来检测建筑物墙外的环境温度，因为需要通过检测同水平高度的环境温度来判断墙体有没有倾斜，所以在安装时需要注意所有红外接收器是否处于同一水平高度。为了解决让所有红外接收器都能在同一水平高度的问题，设计了水平仪组成的水平定位单元，每个红外接收器都与一个水平仪连接，通过这些水平仪确定红外接收器都处于同一水平高度。
在进一步的实施例中，红外接收器安装在建筑物的每一面外墙，确保包围建筑物一圈，检测每个墙面的环境温度，了解建筑物各个方向的环境温度。同一海拔的环境温度相同，且环境温度随海拔高度增加而降低，当建筑物沉降，沉降的墙体海拔高度下降，位于此墙面的红外接收器检测的环境温度比其他墙面的红外接收器检测的环境温度要高，检测结果出现温差则证明建筑物出现沉降现象。
如图2所示，在更进一步的实施例中，所述温度检测单元，包括红外接收电路，包括动态测温模块、多级放大模块；
所述动态测温模块，包括电阻R1、电阻R2、电阻R3、电阻R4、电阻R5、电阻R6、电阻R7、电阻R8、电阻R9、电阻R10、红外接收管D1、二极管D2、二极管D3、运算放大器U1：A、运算放大器U1：B、运算放大器U1：C和电容C1；
所述电阻R1的一端接方波电压，所述电阻R1的另一端分别与所述电阻R2的一端、所述红外接收管D1的正极和所述运算放大器U1：A的反相输入端连接，所述电阻R2的另一端接参考电源电压，所述运算放大器U1：A的同相输入端与所述电阻R3的一端连接，所述电阻R3的另一端接地，所述红外接收管D1的负极分别与所述运算放大器U1：A的输出端、所述电容C1的一端连接，所述电容C1的另一端分别与所述电阻R4的一端、所述电阻R5的一端和所述电阻R9的一端连接，所述电阻R5的另一端接地，所述电阻R4的另一端与所述运算放大器U1：B的同相输入端连接，所述运算放大器U1：B的反相输入端分别与所述电阻R6的一端、所述电阻R7的一端和所述二极管D2的负极连接，所述电阻R6的另一端接地，所述运算放大器U1：B的输出端分别与所述二极管D2的正极、所述二极管D3的负极连接，所述二极管D3的正极分别与所述电阻R7的另一端、所述电阻R8的一端连接，所述电阻R8的另一端分别与所述电阻R10的一端、所述运算放大器U1：C的反相输入端连接，所述电阻R9的另一端与所述运算放大器U1：C的同相输入端连接，所述电阻R10的另一端与所述运算放大器U1：C的输出端连接；
所述多级放大模块，包括电阻R11、电阻R12、电阻R13、电阻R14、电阻R15、电阻R16、电阻R17、电阻R18、可调电阻VR1、可调电阻VR2、运算放大器U1：D、运算放大器U2：A和运算放大器U2：B；
所述电阻R11的一端分别与所述电阻R10的另一端、所述运算放大器U1：C的输出端和所述运算放大器U1：D的同相输入端连接，所述运算放大器U1：D的反相输入端分别与所述运算放大器U1：D的输出端、所述电阻R12的一端连接，所述电阻R12的另一端分别与所述电阻R14的一端、所述电阻R15的一端和所述运算放大器U2：A的反相输入端连接，所述电阻R14的另一端与所述可调电阻VR1的一端连接，所述可调电阻VR1的另一端接地，所述运算放大器U2：A的同相输入端与所述电阻R13的一端连接，所述电阻R13的另一端与所述电阻R17的一端均接地，所述运算放大器U2：A的输出端分别与所述电阻R15的另一端、所述电阻R16的一端连接，所述电阻R16的另一端分别与所述电阻R18的一端、所述运算放大器U2：B的反相输入端连接，所述运算放大器U2：B的同相输入端与所述电阻R17的另一端连接，所述运算放大器U2：A的输出端与所述电阻R18的另一端均接检测信号。
在此实施例中，因为要检测周围环境温度，所以决定采用非接触式测量，实验中使用红外测温来检测温度。红外测温根据周围环境的红外射线判断周围环境温度，不会干扰温度分布。在电路中使用红外接收管根据接收的红外信号变化而改变的脉冲电流来实现动态测温，由所述运算放大器U1：A与所述红外接收管D1组成测量电路，流过所述红外接收管D1包括电流包括方波电压、参考电源电压流过直流分量，所述运算放大器U1：B、所述运算放大器U1：C组成高输入阻抗型精密二极管全波整流电路。
在实验中动态测温模块检测的温度数据精度不够，不能反映温差变化，为了提高温度检测的精度，所以设计了多级放大模块放大检测信号。所述多级放大模块中的第一级放大电路由所述运算放大器U1：D组成的电压跟随器进行阻抗匹配，通过调整所述可调电阻VR1的电阻值，改变输出电压大小。第二级放大电路由所述运算放大器U2：A组成比例加法器，通过调整所述可调电阻VR2的电阻值，使放大比例与第一级放大电路相对应。第三级放大电路由所述运算放大器U2：B组成放大器，通过调整所述电阻R18的电阻值，确定相应的放大倍数。最后得到的检测数据符合预期。
在进一步的实施例中，每日的平衡观测结果保存本地，同时进行上传，第二天清除本地保存数据更新观测结果再次保存，节约系统内存容量。
在进一步的实施例中，观测结果上传云端，云端接收数据保存，当云端接收到温差数据，发送报警信号到绑定的智能终端。

所述多级放大模块，包括电阻R11、电阻R12、电阻R13、电阻R14、电阻R15、电阻R16、电阻R17、电阻R18、可调电阻VR1、可调电阻VR2、运算放大器U1：D、运算放大器U2：A和运算放大器U2：B；
所述电阻R11的一端分别与所述电阻R10的另一端、所述运算放大器U1：C的输出端和所述运算放大器U1：D的同相输入端连接，所述运算放大器U1：D的反相输入端分别与所述运算放大器U1：D的输出端、所述电阻R12的一端连接，所述电阻R12的另一端分别与所述电阻R14的一端、所述电阻R15的一端和所述运算放大器U2：A的反相输入端连接，所述电阻R14的另一端与所述可调电阻VR1的一端连接，所述可调电阻VR1的另一端接地，所述运算放大器U2：A的同相输入端与所述电阻R13的一端连接，所述电阻R13的另一端与所述电阻R17的一端均接地，所述运算放大器U2：A的输出端分别与所述电阻R15的另一端、所述电阻R16的一端连接，所述电阻R16的另一端分别与所述电阻R18的一端、所述运算放大器U2：B的反相输入端连接，所述运算放大器U2：B的同相输入端与所述电阻R17的另一端连接，所述运算放大器U2：A的输出端与所述电阻R18的另一端均接检测信号。
在此实施例中，因为要检测周围环境温度，所以决定采用非接触式测量，实验中使用红外测温来检测温度。红外测温根据周围环境的红外射线判断周围环境温度，不会干扰温度分布。在电路中使用红外接收管根据接收的红外信号变化而改变的脉冲电流来实现动态测温，由所述运算放大器U1：A与所述红外接收管D1组成测量电路，流过所述红外接收管D1包括电流包括方波电压、参考电源电压流过直流分量，所述运算放大器U1：B、所述运算放大器U1：C组成高输入阻抗型精密二极管全波整流电路。
在实验中动态测温模块检测的温度数据精度不够，不能反映温差变化，为了提高温度检测的精度，所以设计了多级放大模块放大检测信号。所述多级放大模块中的第一级放大电路由所述运算放大器U1：D组成的电压跟随器进行阻抗匹配，通过调整所述可调电阻VR1的电阻值，改变输出电压大小。第二级放大电路由所述运算放大器U2：A组成比例加法器，通过调整所述可调电阻VR2的电阻值，使放大比例与第一级放大电路相对应。第三级放大电路由所述运算放大器U2：B组成放大器，通过调整所述电阻R18的电阻值，确定相应的放大倍数。最后得到的检测数据符合预期。
在进一步的实施例中，每日的平衡观测结果保存本地，同时进行上传，第二天清除本地保存数据更新观测结果再次保存，节约系统内存容量。
在进一步的实施例中，观测结果上传云端，云端接收数据保存，当云端接收到温差数据，发送报警信号到绑定的智能终端。多层红外接收器检测的温度结果符合水平面越高，温度越低的结果，当检测到低层环境温度低于高层环境温度，则判断红外接收器可能出现故障，发送提示信号到绑定的智能终端。
在更进一步的实施例中，云端会将近期数据与记录数据进行比对，建筑物没有沉降现象，近期数据应该与记录数据保持在同一个区间变化，当建筑物发生沉降，近期数据变化区间会与记录数据出现偏差，此时云端发送警告信号。
一种基于混沌保密的物联网商品信息防追溯方法，其特征在于，具体步骤包括：
步骤1、在建筑物每一层外墙设置红外接收器，确定同层红外接收器处于同一水平高度；
步骤2、总结红外接收器检测该方向的环境温度，判断同水平高度的红外接收器检测的环境温度是否存在温差；
步骤3、每日更新观测数据，将数据上传云端记录；
步骤4、云端对保存记录数据，当出现非平衡数据记录，云端发送信号进行报警。
总之，本发明具有以下优点：
1、通过检测环境温度判断建筑物平衡状态，在建筑物建成后观测；
2、观测建筑物平衡状态不受建筑物高度影响；
3、观测建筑物平衡状态的同时自检故障；
4、记录观测结果，即便建筑物整体发生沉降也可观测到。
另外需要说明的是，在上述具体实施方式中所描述的各个具体技术特征，在不矛盾的情况下，用于通过任何合适的方式进行组合。为了避免不必要的重复，本发明对各种可能的组合方式不再另行说明。
