Description
技术领域technical field

背景技术Background technique
野外环境考察是一项艰苦的工作。现有的野外环境考察模式基本是野外现场采样，待考察结束后实验室分析。这种模式使得相关专业科研人员耗费大量时间在数据采集上面，不能将主要精力集中在数据分析处理上面，大大限制了专业野外环境考察的效率。而且由于缺乏实时性，样品保存过程中性质发生变化等问题，使采集的数据真实性受到质疑。而随着技术的发展，出现了相关的电子考察设备，如GPS记录仪，便携PH计等，但是由于此类设备功能单一，兼容性差，仍然需要研究人员对数据进行二次整合。因此，新型的野外环境数据综合记录仪拥有着广阔的前景，亟待去开发、设计。Field environmental investigation is hard work. The existing field environmental investigation mode is basically sampling in the field, followed by laboratory analysis after the investigation. This model makes relevant professional researchers spend a lot of time on data collection, and cannot concentrate on data analysis and processing, which greatly limits the efficiency of professional field environmental investigations. Moreover, due to the lack of real-time performance and changes in the properties of samples during storage, the authenticity of the collected data has been questioned. With the development of technology, related electronic investigation equipment has appeared, such as GPS recorder, portable pH meter, etc. However, due to the single function and poor compatibility of such equipment, researchers still need to re-integrate the data. Therefore, the new field environmental data comprehensive recorder has a broad prospect and needs to be developed and designed urgently.

优选的，所述电化学传感器包括PH传感器、温度传感器、湿度传感器、土壤酸碱度传感器。Preferably, the electrochemical sensors include pH sensors, temperature sensors, humidity sensors, and soil pH sensors.
将环境数据采集子系统和数据存储分析子系统分别开机，将特定的传感器连接到环境数据采集子系统的接口上，开机选择传感器类型，并与数据存储分析子系统通过无线自动连接。将传感器放入待测环境，并启动数据存储分析子系统记录数据。例如，在测量水体PH值时，直接将PH值传感器放入待测水体中，开启数据存储分析子系统PH值数据记录功能，并自动与定位模块相关联。环境数据采集子系统将根据预设的时间间隔对数据进行采集，实时记录水体的PH值以及所在的经纬度值。通过2.4G频段的无线传输设备将数据实时传输至数据存储分析子系统中。数据存储分析子系统对收到的数据依据数据的出现频次建立哈弗曼编码表，通过哈弗曼编码对数据进行压缩，减小单位数据的存储空间，提高整体的存储容量。根据所选用的传感器特点，可对数据进行简单的分析，如针对PH传感器，可在液晶屏上画出其PH值随时间变化的实时曲线。对明显异常值或突变值等，可进行相应的标定。同时，在数据存储分析子系统中，提供相应的搜索、设置等功能。待野外地理考察结束后，将数据存储分析子系统与PC机连接，即可对数据进行进一步处理分析。The environmental data acquisition subsystem and the data storage and analysis subsystem are turned on separately, specific sensors are connected to the interface of the environmental data acquisition subsystem, the sensor type is selected after starting up, and the data storage and analysis subsystem is automatically connected wirelessly. Put the sensor into the environment to be tested, and start the data storage and analysis subsystem to record the data. For example, when measuring the pH value of a water body, directly put the pH value sensor into the water body to be measured, turn on the pH value data recording function of the data storage and analysis subsystem, and automatically associate with the positioning module. The environmental data acquisition subsystem will collect data according to the preset time interval, and record the pH value of the water body and the latitude and longitude value in real time. The data is transmitted to the data storage and analysis subsystem in real time through the wireless transmission equipment in the 2.4G frequency band. The data storage and analysis subsystem establishes a Huffman coding table for the received data according to the frequency of occurrence of the data, and compresses the data through Huffman coding to reduce the storage space of unit data and increase the overall storage capacity. According to the characteristics of the selected sensor, the data can be simply analyzed. For example, for the pH sensor, the real-time curve of its pH value changing with time can be drawn on the LCD screen. Corresponding calibration can be carried out for obvious outliers or mutation values. At the same time, in the data storage and analysis subsystem, corresponding functions such as search and setting are provided. After the field geographical investigation is completed, the data storage and analysis subsystem is connected to the PC, and the data can be further processed and analyzed.
与现有技术相比，本发明的有益效果为：Compared with prior art, the beneficial effect of the present invention is:
1.本发明解决现有设备功能单一的不足；一方面：现有设备比如检测水体酸碱度的PH计，检测空气温湿度的温湿度计。这些设备功能单一，且一般无数据记录功能，即需要我们在自行测量各项数据后，记录数据，最后实验室再进行进一步的数据处理。另一方面，由于设备功能单一，在外出考察的时候无法携带大量的仪器设备，以至于有些参数必须将样品带回实验室进行分测试。1. The present invention solves the shortcomings of the single function of the existing equipment; on the one hand: the existing equipment such as a PH meter for detecting the pH of water, and a thermo-hygrometer for detecting air temperature and humidity. These devices have a single function and generally have no data recording function, that is, we need to record the data after measuring various data by ourselves, and finally the laboratory will carry out further data processing. On the other hand, due to the single function of the equipment, it is impossible to carry a large number of instruments and equipment when going out for inspections, so that some parameters must be brought back to the laboratory for sub-testing.
2.本发明解决传感器与控制器之间模块化连接问题，将特定传感器与相应的信号调理电路组合在一起，所得到的信号可以直接送AD转换器，这种模块化的集成方法，一方面可以在增加测量参数的时候，无需修改整个系统设计，只需将传感器与信号调理电路组合成前端信号采集模块，然后将可直接进行AD转换的信号送入控制器，大大减轻了系统的后期升级负担。2. The present invention solves the problem of modular connection between the sensor and the controller. The specific sensor is combined with the corresponding signal conditioning circuit, and the obtained signal can be directly sent to the AD converter. This modular integration method, on the one hand When adding measurement parameters, there is no need to modify the entire system design, just combine the sensor and signal conditioning circuit into a front-end signal acquisition module, and then send the signal that can be directly converted to AD to the controller, which greatly reduces the later upgrade of the system burden.
3.本发明解决数据记录问题，利用上下位机的设计，将数据最终存储在外接可移动数据存储设备中。在野外考察结束后回实验室进行数据分析。可将移动数据存储设备所采集的数据送到PC机中。解决现阶段还存在的手抄笔记的环境考察的落后状态。3. The present invention solves the problem of data recording, and finally stores the data in an external removable data storage device by utilizing the design of the upper and lower computers. After the field trip, return to the laboratory for data analysis. The data collected by the mobile data storage device can be sent to the PC. Solve the backwardness of the environmental investigation of handwritten notes that still exists at this stage.
本发明中所述的传感器主要为电化学传感器，主要对空气成分和水体水质，土壤土质进行现场测试。主要应用方向为野外环境科学研究，由所挂载的传感器决定所测量的参数指标。The sensor described in the present invention is mainly an electrochemical sensor, which mainly conducts field tests on air components, water quality and soil quality. The main application direction is field environmental scientific research, and the measured parameters are determined by the mounted sensors.
4.本发明建立环境数据多维度融合，利用基于同一台设备所获得的各种传感器数据，并与定位模块得到的地理信息形成一一映射关系，可以得到一个地区的全面环境数据指标。在大数据的背景下，直接获得已经融合的数据将大大减轻后续数据处理的时间。4. The present invention establishes multi-dimensional fusion of environmental data, uses various sensor data obtained based on the same device, and forms a one-to-one mapping relationship with geographic information obtained by the positioning module, and can obtain comprehensive environmental data indicators for a region. In the context of big data, directly obtaining fused data will greatly reduce the time for subsequent data processing.
