具体实施方式
下面结合附图和实施例对本申请作进一步的详细说明。图1是本申请实施例提供的GNSS接收机的方框示意图。如图1所示，该GNSS接收机100，包括：状态监测传感器1和处理器2，其中，状态监测传感器1配置为，监测GNSS接收机100的状态，并根据GNSS接收机100的状态生成第一触发信号；处理器2配置为，根据第一触发信号由休眠工作状态切换到唤醒工作状态，并以预设频率向远程服务器3发送GNSS接收机100的位置信息。
GNSS接收机100的位置状态可及时反映安装该GNSS接收机100的地貌或地势的变化情况，当地貌或地势发生变化时，GNSS接收机100的位置状态会随之发生变化。举例来说，在某块儿山体上安装设置有GNSS接收机100，当山体发生滑坡时，GNSS接收机100的位置状态由初始的状态发生了移位，即GNSS接收机100的当前位置与初始位置相比发生了变化。因此当GNSS接收机100的状态发生变化时，可反映该处的地貌或地势发生变化。其中，将GNSS接收机100的位置状态是否发生变化定义为GNSS接收机100的状态。
状态监测传感器1配置为监测GNSS接收机100的位置状态是否发生变化，当状态监测传感器1监测到GNSS接收机100的位置状态发生变化时，则判断地貌、地势发生变化，并生成第一触发信号。此时，处理器2根据该第一触发信号由休眠工作状态切换至唤醒工作状态，并以预设频率向远程服务器3发送GNSS接收机100的位置信息，以提醒工作人员当前GNSS接收机100所在的位置的地貌或地势发生变化。本实施例可以避免在地貌或地势未发生变化时，处理器2仍处于唤醒状态，一直向远程服务器3发送GNSS接收机100的位置信息，浪费电能。
可选地，状态监测传感器1为加速度传感器，加速度传感器配置为，监测GNSS接收机100的加速度；以及当GNSS接收机100的加速度大于第一预设值时，生成第一触发信号。
当GNSS接收机100的加速度大于第一预设值时，认为GNSS接收机100的位置状态发生了变化。其中，第一预设值可以为50mg～200mg。即，当加速度传感器监测到GNSS接收机100的加速度大于第一预设值时，生成第一触发信号，触发处理器2由休眠工作状态切换为唤醒工作状态。其中，状态监测传感器1可以为加速度传感器，加速度传感器的型号可以选择ADXL362型号加速度传感器。
可选地，处理器2还配置为，响应于，连续N次向远程服务器3发送的GNSS接收机100的位置信息，由唤醒工作状态切换至休眠工作状态，其中，N为正整数。
当处理器2处于唤醒工作状态之后，以预设频率向远程服务器发送GNSS接收机100的位置信息，其中，预设频率可以根据实际情况而定。可选的，预设频率是1Hz，当处理器2连续5分钟～10分钟向远程服务器发送的GNSS接收机100的位置信息均相同或者接近相同(两两之间的差值小于一定阈值，即，差值几乎可以忽略不计)时，可以判断GNSS接收机100的位置状态几乎保持不变，进而处理器2由唤醒工作状态切换至休眠工作状态。其中，N值可选为400次。
在安装好GNSS接收机100，并调试好之后，处理器2默认状态处于休眠状态，当状态监测传感器1监测到GNSS接收机100的状态发生变化时，生成第一触发信号，第一触发信号触发处理器2由休眠工作状态切换为唤醒工作状态，处理器2以预设频率向远程服务器3发送GNSS接收机100的位置信息，并在 连续N次发送的GNSS接收机100的位置信息均相同或者接近相同时，触发处理器2由唤醒工作状态切换至休眠工作状态。
其中，在处理器2处于休眠工作状态时，仅接收来自状态监测传感器1的第一触发信号。即在处理器2处于休眠工作状态时，状态监测传感器1一直处于工作状态，并且该状态监测传感器1有动静触发功能，状态监测传感器1检测到超过第一预设值后，将第一触发信号即中断信号发送给接收机100中的处理器2，唤醒处理器2并将GNSS接收机100最新的位置信息数据上传至远程服务器3。
可选地，如图2所示，GNSS接收机100还包括：定时器4，定时器4配置为，在处理器2由唤醒工作状态切换至休眠工作状态的情况下启动计时，并当定时器4记录的时长大于第二预设值时，定时器4生成第二触发信号；处理器2根据第二触发信号，或，根据第一触发信号，由休眠工作状态切换至唤醒工作状态，进而，避免处理器2长时间未接收到第一触发信号时，远程服务器3长时间接收不到GNSS接收机100的位置信息，定时器4与状态监测传感器1配合使用，有利于在保证处理器2低功耗工作的基础上，还可及时监测GNSS接收机100的位置状态。
当定时器4记录处理器2处于休眠工作状态的时长大于第二预设值时，生成第二触发信号，触发处理器2由休眠工作状态切换至唤醒工作状态。在定时器4记录处理器2处于休眠工作状态的时长的同时，状态监测传感器1也同时在监测GNSS接收机100的状态，当定时器4记录的时长大于第二预设值或者状态监测传感器1监测的GNSS接收100的状态发生变化时，两者中仅有一个条件满足时，处理器2由休眠工作状态切换为唤醒工作状态。从而避免当地势或者地貌长时间不发生变化时，遗漏该处GNSS接收机100的位置信息。
其中，处理器2可以采用SAMA5型号处理器，其集成DDR(Double Data Rate SDRAM，双倍速率同步动态随机存储器)功能，单芯片功耗小于0.25W，SAMA5型号处理器可以通过定时器4或状态监测传感器1进行唤醒。
第二预设值的设定可根据地势或地貌的变化情况而定。如果地势或地貌的变化比较快速，那么第二预设值可以设置的较小一些；如果地势或地貌的变化比较慢速，那么第二预设值可以设置的较大一些。举例来说，刚安装好GNSS接收机100时，地势或地貌并不会很快发生变化，处理器2可能还接收不到第一触发信号，此时，第二预设值可以设置为6个小时。当处理器2接收到一次第一触发信号时，第二预设值可以设置为3个小时。当处理器2接收到两次或者更多次触发信号时，第二预设值可以设置为半个小时，或者几分钟。随着处理器2接收到第一触发信号的频次越来越高，说明地势或地貌变化的越来越快，因此，将第二预设值设置较短一些，有利于及时监控GNSS接收机100当前的位置信息。
通过定时器4和状态监测传感器1两者的相互配合，使得GNSS接收机100的处理器2在可以满足传输GNSS接收机100的位置信息的基础上，还可以在一定时间段内处于休眠状态，有利于降低功耗，节省电能。
可选地，如图3所示，GNSS接收机100还包括：网络模块5，当处理器2处于唤醒工作状态时，网络模块5配置为在处理器2与远程服务器3之间建立通信。
网络模块5可以为WIFI模块或4G/5G全网通等网络模块。在处理器2处于唤醒工作状态时，网络模块5开始工作，以建立处理器2与远程服务器3之间的通信连接，进而使得处理器2可以向远程服务器3发送GNSS接收机的位置信息。需要说明的是，网络模块5还可以为本领域技术人员公知的网络模块5， 在此不作具体限制。
可选地，如图4所示，GNSS接收机100还包括：全球卫星导航模块6，当处理器2处于唤醒工作状态时，全球卫星导航模块6配置为以预设频率获取GNSS接收机100的位置信息，并发送至处理器2。
全球卫星导航模块6可以为SOC技术下的高精度定位模块，一颗芯片集成卫星信号接收和解调功能，并通过串口输出原始观测量，即与处理器2进行串口通讯，支持北斗、GPS、GOLNASS卫星系统，静态水平精度优于2.5mm，高程精度优于5mm，其功耗只有0.3w，成本比高精度板卡低很多，并可以满足作业需求。全球卫星导航模块6在处理器2处于唤醒工作状态时，接收全球卫星导航系统发出的卫星信号，即GNSS接收机100的位置信息，并发送至处理器2，处理器2通过网络模块5将GNSS接收机100的位置信息发送至远程服务器3，以供工作人员观测GNSS接收机100的安装的地势或地貌的变化情况。
当处理器2处于休眠工作状态时，全球卫星导航模块6也处于休眠状态，不接收全球卫星导航系统发出的卫星信号。进而有利于降低电能的消耗。
采用低功耗处理器2和全球卫星导航模块6，精减功能，并且采用休眠、唤醒的工作方式，其中，唤醒采用定时唤醒和触发唤醒两种方式。在保证实用功能和性能的前提下，降低GNSS接收机100的功耗和成本。
可选地，如图5所示，全球卫星导航模块6、网络模块5、定时器4、状态监测传感器1和处理器2集成设置在主线路板7上，使得主线路板7集成化，节省主线路板7在GNSS接收机100内部的占用空间。
主线路板7可为PCBA主线路板。PCBA主线路板上还集成有电源处理模块(图中未示出)，电源处理模块用于将外部电源的电压或电流转换为可供处理器2使用的电压或电流。
可选地，如图6所示，GNSS接收机100还包括：外壳8、屏蔽盒9和天线10，屏蔽盒9位于外壳8内部，主线路板7位于屏蔽盒9内部，天线10位于屏蔽盒9外部；其中，主线路板7中设置第一射频接口11，天线10设置第二射频接口12，屏蔽盒9设置有通孔，第一射频接口11与第二射频接口12贯穿通孔对插连接，通过对插连接，省去了射频线的使用，节省材料，安装快捷方便。
天线10和主线路板7通过第一射频接口11与第二射频接口12对插连接，天线10和主线路板7之间有屏蔽盒9隔离，天线10、主线路板7和屏蔽盒9集成在一个结构外壳8内，使得GNSS接收机100实现一体设计。
可选地，天线10集成全球卫星导航模块6的天线和网络模块5的网络天线于一体，使得GNSS接收机100的重量变轻，并且去掉了常规的外置吸盘式天线，增强了移动信号接收和发送的能力。
天线10可以采用空气介质天线，重量轻，天线10兼容了两个2.4GHz的移动网络天线，可实现在天线10体积不变的基础上，一个天线兼容两个功能。将全球卫星导航模块6的天线和网络模块5的网络天线设置为一体，体积只有一个常规接收机的大小，并且在GNSS接收机100内部，天线10和主线路板7之间通过第一射频接口11与第二射频接口12对插的方式连接，最大程度的使得GNSS接收机100一体化，集成化，结构简单，成本低廉和安装复杂度降低。
天线10集成全球卫星导航模块6的全频天线和网络模块5的4G全网通网络天线，形成一体式多模多频组合天线，同时接收或发送信号，两种天线的接收或发送信号的频段不同，可以避免两者之间相互干扰。
可选地，如图6、图7和图8所示，外壳8包括：第一壳体81、第二壳体82和密封垫83，第一壳体81的端面、密封垫83和第二壳体82的端面通过螺栓固定连接，密封垫83过盈设置在第一壳体81的端面和第二壳体82的端面之 间。
密封垫83密封之后，过盈尺寸可以为0.6mm，使得壳体8的密封性良好，保障GNSS接收机100可以在户外长期应用。密封垫83可以为硅胶圈。
可选地，如图6所示，第一壳体81包括圆台侧面811，以及由圆台侧面向外延伸形成的弧形盖812。
第一壳体81的圆台侧面811的端面与第二壳体82的端面通过螺栓连接。两者还可以通过本领域技术人员熟知的其他连接方式连接，在此不做具体限定。
可选地，如图8所示，圆台侧面811的母线与圆台侧面811的中心轴线之间的夹角范围为1°-5°，可选为2°。这种结构的设置有利于雨水等的下落，避免腐蚀GNSS接收机100的外壳。
可选地，如图7所示，第二壳体82的端面设置有第一台阶821，第一台阶821沿第二壳体82外部指向内部的方向，由低到高设置，避免雨水下落时，进入壳体内部，造成内部零部件损坏。
第二壳体82外部指向内部的方向为如图7中所示的第一方向001，即箭头方向。第一台阶821由低到高设置，即，沿第一方向001，先低后高设置。
可选地，如图7所示，第一壳体81的端面设置有第二台阶813，第二台阶813沿第一壳体81外部指向内部的方向，由高到低设置。
图7中的第一方向001即为第一壳体81外部指向内部的方向，第二台阶813由高到低设置。需要说明的是，第一台阶821与第二台阶813相互交错适配设置，避免雨水沿圆台侧面811流下流入壳体内部，腐蚀壳体8内部的零部件。
可选地，第一台阶821沿第二壳体82垂直指向第一壳体81的方向，高度范围为0.5mm-2mm，工艺制程简单。
第二壳体82垂直指向第一壳体81的方向即为如图8所示的第二方向002， 第一台阶821的高度可选为0.9mm。
由此，通过第一壳体81和第二壳体82的设置，有利于防止GNSS接收机100进水。并且通过屏蔽盒9、天线10以及主线路板7的集成设置，有利于GNSS接收机100的集成化，一体化，降低了后期安装的复杂程度。另外，通过处理器2的休眠工作状态以及唤醒工作状态的切换，降低了GNSS接收机的空闲时段功耗，节省了电能的使用，进而提高系统续航时间。即系统集成度高，各组成部分数量减少，节省运输、安装的消耗。在传统方案上，它把天线和GNSS接收机这两大核心功能整合到一个结构内，实现一个常规天线的体积兼有天线和GNSS接收机的功能，去掉了原有的天线罩。
综上所述，根据本申请实施例提出的GNSS接收机100，通过状态监测传感器1监测GNSS接收机100的状态，并根据该GNSS接收机100的状态生成第一触发信号，处理器2根据该第一触发信号由休眠工作状态切换到唤醒工作状态，并以预设频率向远程服务器3发送GNSS接收机100的位置信息，从而使得处理器2根据GNSS接收机100的状态变化切换工作状态，在GNSS接收机100的状态未变化时，处理器2处于休眠工作状态，从而节省功耗，降低电量的使用。
图9是本申请实施例提出的GNSS设备结构示意图。结合图9和图10所示，GNSS设备200，包括GNSS接收机100、固定柱300、锂电池400和太阳能电池板500，太阳能电池板500位于固定柱300的侧面，锂电池400吊挂在固定柱300内部，GNSS接收机100固定在固定柱300的顶部；太阳能电池板500配置为向锂电池400充电；锂电池400通过数据线与GNSS接收机100连接，配置为向GNSS接收机100供电，并向GNSS接收机100发送锂电池400的数据。
由于GNSS接收机100中处理器2的休眠工作状态以及唤醒工作状态之间 的切换，使得GNSS接收机功耗低，由此，采用锂电池替代铅酸蓄电池，不但可满足供电需求，而且在安装方面也无需用土掩埋，施工简单，操作方便，很大程度提高了施工进程。
GNSS接收机100与固定柱300之间通过法兰固定连接。固定柱300可以为钢管，顶部焊接法兰，GNSS接收机100下部设置带法兰的底座，带法兰的底座通过螺栓与固定柱300顶部的法兰固定连接。锂电池400与GNSS接收机100之间通过数据线连接。太阳能电池板500与锂电池400电连接。太阳能电池板500将太阳能转化为电能，并向锂电池400充电，锂电池400通过数据线向GNSS接收机100供电，并向GNSS接收机100发送锂电池400的电池数据信息。

需要说明的是，GNSS设备200供电采用智能锂电池，锂电池内部集成太阳 能充电、电量计算、温度传感器采集功能，可以实现对GNSS设备的供电系统的状态监测。电量计401具体可以监测到太阳能电池板500的电压，锂电池400的电压、充电电流、电池温度、电池剩余电量、预计使用时间等状态信息。当GNSS接收机100中的处理器2处于休眠工作状态时，电量计401并不上传上述电池数据信息，仅当处理器2处于唤醒工作状态时，电量计401将上述电池数据信息上传至GNSS接收机100，进而有利于降低整个GNSS设备200的功耗。接着GNSS接收机100将上述电池数据信息通过网络模块5发送至远程服务器3，以供工作人员参考。
该GNSS设备200的供电电池采用智能锂电池，减少了电池体积，采用吊挂方式将智能锂电池吊挂在GNSS接收机100下方，且安装在固定柱300内，减少施工复杂度，可以快速部署。其中，吊挂时，可在固定柱300内部设置与固定柱300轴线垂直的横杆，横杆焊接在固定柱300内部，并在锂电池400的上部设置挂钩，将其挂在横杆上。或者还可以使用本领域人员熟知的其他能将锂电池400吊挂在固定柱300内的方式，此处不做具体限定。
通过将主线路板7上集成全球卫星导航模块6、网络模块5、处理器2、状态监测传感器1和定时器4使得主线路板7集成度更高，并且4G全网通网络天线和全球卫星导航模块天线集成化，以及天线10与主线路板7集成化，使得GNSS设备集成度高，体积小。采用嵌入式系统使得处理器2在休眠工作状态以及唤醒工作状态之间切换，大幅度降低了GNSS接收机100的功耗，进而降低了锂电池400容量和太阳能功率配比，从而降低了建站成本，进而可以减少锂电池体积，减轻电池重量，可以缩短建站时间，适合快速部署，方便用户维护。该GNSS设备去除了基柜和天线罩，延长系统续航时间，适合在复杂的野外地形架设，降低人工运输难度，降低施工负责程度。从而得以实现一种全地型、 全天候、低成本、高精度、高集成度的简易GNSS设备。
综上所述，根据本申请实施例提出的GNSS设备，通过GNSS接收机中处理器的低功耗工作状态设置，使得GNSS接收机中对电能的需求降低，进而仅通过太阳能电池板以及锂电池的配合设置即可满足GNSS接收机的供电需求；锂电池吊挂在固定柱内部，施工方便，使得GNSS设备结构简单，有利于缩短工期。
