Abstract

Description

传感器及数据采集系统 技术领域
本文涉及但不限于通信安全技术领域，尤其涉及一种基于传感器及数据采集系统。
背景技术
传感器的应用范围非常广泛，但是，在某些特殊领域(例如高压输变线路监测、油气管路等)，对可以不受电磁干扰、无外部供电、无电线或者光纤长距离铺设，在恶劣环境的无人值守之下还能正常运行的传感器件存在很大的市场需求。
传统的传感器通常包括有源传感器和无源传感器，有源传感器包括烟雾传感器、视频传感器等，如图1所示，其器件内部需要一个电源进行器件持续供电，外部需要传感器用电力线与远程监控电脑连接，以便将传感器的信息实时通过电力线通讯的方式输入监控电脑。然而，这种类型的传感器由于自身携带电源，体积较大，同时器件外部需要电力线通讯使得系统无法无源，铺设监控电脑与传感器之间的电力线也增加了工程的复杂度，而且一些希望无电磁干扰的环境也不适合。
无源传感器包括光纤传感器、光纤光栅传感器等，如图2所示，其器件内部虽然不需要供电电源，但是外部需要光纤传感器与一个信号发送接收处理器相连，以便传感器的光波激励与信号的接收显示，这种类型的传感器虽然是无源的，但是仍然需要器件与信号发送接收设备之间铺设光纤，同样增加了工程难度，而且线路上光纤的扰动也会干扰无源传感器信号返回后的解调，出现信息误判或者错判的情况。
相关技术中还有一种带RFID(Radio Frequency Identification，射频识别)标签的传感器，如图3所示，是由RFID和传统传感器组成的一种传感器，通讯方式如图4所示，RFID读写头需要通过天线与带RFID标签的传感器之间进行射频信号的交互，包括进行数据的传输以及发送命令，由于这种带 RFID的传感器本身发出的射频信号对外界环境就是一种信号干扰，因此，对某些不希望有电磁干扰的环境并不适用。

本发明的实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
本发明实施例中，通过将OEID标签与传统传感器(传感探头)集成形成传感器件，由于OEID标签本身具有光无线通讯、光无线充电和数据存储的功能，使得传统的传感器加上OEID标签形成的传感器件具有对外界环境无电磁干扰，器件内部不需要电源，外部线路上不需要电力线或者光纤连接，传感信号接收准确不受外界电磁干扰的优点，并使得形成的传感器件体积小，减少工程难度和成本。
由于相关技术中的传感器通常体积大、对外界环境造成电磁干扰；外部线路上需要电力线或者光纤连接，增加了工程复杂度，而且传感信号易受外界电磁干扰而不准确。
本发明实施例提供一种解决方案，可以使得传感器件不对外界环境造成电磁干扰，器件内部不需要电源，外部线路上不需要电力线或者光纤连接，减少工程复杂度，传感信号接收准确不受外界电磁干扰。
如图5所示，本发明实施例提出一种数据采集系统，包括OEID读写头以及与所述OEID读写头通讯连接的传感器，所述传感器设置成监测外部环境参数，并通过光信号与所述OEID读写头之间进行数据传输。
其中，所述传感器中可以包括OEID标签，所述OEID标签具有光无线通讯、光无线充电和数据存储等功能。
可选地，本实施例OEID读写头与传感器之间的光信号通讯包括上行通讯和下行通讯，其中：
所述下行通讯中，所述OEID读写头通过光控制命令控制所述传感器，且OEID读写头以及外界光源对传感器进行光无线充电；
所述上行通讯中，所述传感器在接收到所述光控制命令后对所述OEID读写头进行数据实时回复；所述数据包括但不限于监测数据。
本实施例通过将OEID标签与传统传感器(传感探头)集成形成传感器件，由于OEID标签本身具有光无线通讯、光无线充电和数据存储的功能，使得传统的传感器加上OEID标签形成的传感器件具有对外界环境无电磁干扰，器件内部不需要电源，外部线路上不需要电力线或者光纤连接，传感信号接收准确不受外界电磁干扰的优点，并使得形成的传感器件体积小，减少工程难度和成本。
可选地，本实施例的传感器可以包括：OEID标签以及与所述OEID标签通讯连接的至少一传感探头，所述传感探头设置成监测外部环境参数，所述OEID标签设置成将所述传感探头监测到的外部环境参数进行存储并对外传输。
本发明实施例可选方案中提供了两种传感器结构，其中一种传感器结构如图6所示，一个OEID标签与一个传统传感探头进行集成形成单个传感器器件，此时，传统传感探头设置成进行特定传感参量(例如：风速、温度、压力、湿度、流量等外部环境参数)的实时监测，而OEID标签则设置成将实时监测到的外部环境参数进行存储并传输。
另一种传感器结构如图7所示，一个OEID标签与监测不同参量(本实施例以三个进行举例)的传统传感探头进行集成形成的单个传感器器件，设置成监测不同参量的传统传感探头设置成分别对外部环境参数进行监测，而OEID标签则设置成将实时监测到的不同外部环境参数进行存储并传输。
在其它可选方案中，所述OEID标签可以周期性获取并存储所述传感探头监测到的外部环境参数，在外界需要读取监测数据时进行传输；也可以在外界需要读取监测数据时才获取并存储所述传感探头监测到的外部环境参数；获取外部环境参数时，可以是OEID标签主动获取，也可以是传感探头主动上报给OEID标签。
可选地，如图8所示，OEID标签包括：控制芯片，以及均与控制芯片连 接的电源管理模块、数据存储模块、光发射器件和PVD(Photonic Voltage Detector，光子电压检测器)模块，其中：
所述PVD模块设置成接收所述OEID读写头发送的光控制命令及外界光，将所述光控制命令发送至所述控制芯片，并将外界光转化为电能提供给所述电源管理模块；
所述电源管理模块设置成对所述传感器进行工作电能供给；
所述数据存储模块设置成获取所述传感探头监测到的外部环境参数并存储为监测数据；
所述控制芯片设置成在接收到所述PVD模块发送的光控制命令后，从所述数据存储模块中调取所述监测数据，并将调取的所述监测数据转化为所述光发射器件的驱动电流，使得所述光发射器件将所述监测数据加载到光信号上发送给所述OEID读写头。
其中，所述光发射器件可以但不限于为LED(Light Emitting Diode，发光二极管)模块。
可选地，所述OEID标签还包括：设置成对所述电源管理模块提供的电能进行存储的储能电池。所述储能电池与所述电源管理模块连接；可以但不限于为蓄电池。
以下分别阐述上述图6和图7两种传感器结构结合上述OEID标签的内部结构及工作原理如下：
如图9所示，传感器的第一种内部结构及工作原理如下：
PVD模块接收外界命令信号及外界光，其中外界光会被转化成电能储备在电源管理模块，用于传感器的正常工作电能供给，单个传感探头将监测到的外部环境数据实时送入数据存储模块，保存为监测数据，控制芯片收到PVD模块的外界命令信号后，从数据存储模块中调取实时监测数据，调取的监测数据转化为光发射器件LED的驱动电流，使得LED将监测数据加载到光信号上对外界发送。
传感器的第二种内部结构如图10所示：由于有些情况下，外界不仅仅需要监测单一参量，而是需要监测多种参量，在这种情况下，需要多个负责不 同传感参量监测的传统传感探头与同一个OEID标签进行集成。工作原理如下：
PVD模块接收到外界命令信号及外界光，其中外界光会被转化成电能储备在电源管理模块，用于传感器的正常工作电能供给，由于此传感器监测及传送的数据量较多，传统传感探头也增多，因此，在电源管理模块中增加储能电池(即图10中的蓄电池)将外界光转化后没有及时用完的电能进行储备，因此，本实施例中OEID标签还可以包括设置成对电源管理模块提供的电能进行存储的储能电池。
多个传感探头分别将监测到的外部环境数据实时送入数据存储模块，保存为监测数据，其中，可以将一个传感探头监测到的外部环境数据保存为一组监测数据；控制芯片收到PVD模块接收到并转发的外界命令信号后，从数据存储模块中调取实时多组监测数据，调取的多组监测数据通过控制芯片转化为光发射器件LED的驱动电流，使得LED将多组监测数据(一起或分别)加载到光信号上对外界发送。
本实施例传感器与OEID读写头的通讯流程如图11所示，包括：
启动OEID读写头；
OEID读写头对指定ID的传感器下发指令，即进行问询；
传感器中的PVD模块接收指令；
当PVD模块接收到表示问询的指令后，传感器将内部的监测数据通过光发射器件LED发送到OEID读写头的接收端，即进行回复；
OEID读写头接收上行信号；
当数据接收完毕后，OEID读写头发送表示结束读取的结束命令。
传感器的PVD模块接收指令；
当PVD模块接收到结束命令后，所传感器控制所述光发射器件LED回复结束发送命令并关闭LED发射。
OEID读写头接收上行信号，接收到相应传感器的LED回复的结束发送命令后也关闭读写头的读取功能。
由此，通过将OEID标签与传统传感器(传感探头)集成形成本实施例的传感器件，由于OEID标签本身具有光无线通讯、光无线充电和数据存储的功能，使得传统的传感器加上OEID标签形成的传感器件具有对外界环境无电磁干扰，器件内部不需要电源，外部线路上不需要电力线或者光纤连接，传感信号接收准确不受外界电磁干扰的优点，并使得形成的传感器件体积小，减少工程难度和成本。
此外，本发明实施例还提供一种传感器，该传感器与外部OEID读写头通讯连接，该传感器包括：OEID标签以及与所述OEID标签通讯连接的至少一传感探头，所述传感探头设置成监测外部环境参数，所述OEID标签设置成将所述传感探头监测到的外部环境参数进行存储并对外传输。

另一种传感器结构如图7所示，一个OEID标签与监测不同参量(本实施例以三个进行举例)的传统传感探头进行集成形成的单个传感器器件，设置成监测不同参量的传统传感探头设置成分别对外界进行监测，而OEID标签则设置成将实时监测到的不同外部环境参数进行存储并传输。
在其它可选方案中，所述OEID标签可以周期性获取并存储所述传感探头监测到的外部环境参数，在外界需要读取监测数据时进行传输；也可以在外界需要读取监测数据时才获取并存储所述传感探头监测到的外部环境参数；获取外部环境参数时，可以是OEID标签主动获取，也可以是传感探头主动上报给OEID标签。
本实施例中，如图8所示，OEID标签包括：控制芯片，以及均与控制芯片连接的电源管理模块、数据存储模块、光发射器件和PVD模块，其中：

传感器的第二种内部结构如图10所示：由于有些情况下，外界不仅仅需要监测单一参量，而是需要监测多种参量，在这种情况下，需要多个负责不同传感参量监测的传统传感探头与同一个OEID标签进行集成。工作原理如下：
PVD模块接收到外界命令信号及外界光，其中外界光会被转化成电能储备在电源管理模块，用于传感器的正常工作电能供给，由于此传感器监测及 传送的数据量较多，传统传感探头也增多，因此，在电源管理模块中增加储能电池(即图10中的蓄电池)将外界光转化后没有及时用完的电能进行储备，因此，本实施例中OEID标签还可以包括设置成对电源管理模块提供的电能进行存储的储能电池。
