It is one of the important means of real-time detection and monitoring, which greatly improves the detection efficiency and automation level. Generally speaking, the existing portable water quality analyzer consists of the following parts: data acquisition unit, data processing unit, data transceiver unit and power supply unit. The data processing unit of the portable water quality analyzer is generally non-standard equipment, and the interface with the data acquisition unit is also specific. Therefore, only a specific water quality index can be detected, which affects the scalability of the equipment; data processing and analysis are carried out in the field , there are few analysis items, but they need to be processed quickly and timely. Due to the low signal strength in the field, sometimes they cannot be sent out in time, which affects data analysis; and the high cost and difficulty of developing non-standard equipment also restrict the promotion of portable water quality analyzers. At the same time, the separate data transceiver unit and separate power supply unit also affect its portability; therefore, the existing portable water quality analyzer is very inconvenient for outdoor water quality on-site detection. the

本实施例1，分别包括两部分，一部分包括多个独立的智能数据采集模块，分别为温度智能数据采集模块、PH值智能数据采集模块、电导率智能数据采集模块、溶解氧智能数据采集模块、氨氮智能数据采集模块；独立的智能数据采集模块将采集到的有效信号传输到A/D转换器进行模数转换，转换后的数据通过16位差分数据总线传输到处理器，而后处理器将处理后的数据通过SPI总线传输到无线传输模块，然后通过无线传输模块和无线网络模块将数据上传到移动终端的微处理器，同时，微处理器可以通过无线网络模块将信息传向监测中心。 This embodiment 1 includes two parts respectively, one part includes a plurality of independent intelligent data acquisition modules, which are temperature intelligent data acquisition module, PH value intelligent data acquisition module, conductivity intelligent data acquisition module, dissolved oxygen intelligent data acquisition module, Ammonia nitrogen intelligent data acquisition module; the independent intelligent data acquisition module transmits the collected effective signals to the A/D converter for analog-to-digital conversion, and the converted data is transmitted to the processor through the 16-bit differential data bus, and the post-processor will process the The final data is transmitted to the wireless transmission module through the SPI bus, and then the data is uploaded to the microprocessor of the mobile terminal through the wireless transmission module and the wireless network module. At the same time, the microprocessor can transmit the information to the monitoring center through the wireless network module.
其中，处理器采用Marvell公司的PXA322，运行频率可达624MHz，并集成了存储单元控制器、时钟和电源控制器、SPI总线控制器等。温度传感器采用DS18B20型号，测量温度范围为-55℃——+125℃，固有测温分辨率为0.1℃。PH值传感器采用PH复合电极，通过测量电动势来确定待测离子活度的方法。电导率传感器通过产生高稳定度的正弦波信号加到电极上，流过电极的电流于被测溶液的电导率成正比，然后将电流由高阻抗运算放大器转化为电压信号进行采样。溶解氧传感器：通过在一个被选择性薄膜封闭的充满电解液的腔室两极施加电压，使进入腔室内的氧气在阴极上被电离，释放出电子形成电流，而透过膜的氧量与水中溶解氧的量成正比，检测电流的大小（同样是由阻抗运算放大器转化为电压信号进行采样）得到溶解氧的含量。氨氮传感器采用氨气敏电极法，在pH值大于11的环境下，铵根离子向氨转变，氨通过氨敏电极的疏水膜转移，造成氨敏电极的电动势的变化，仪器根据电动势的变化测量出氨氮的浓度。A/D转换器采用LTC2208，采样频率能够达到130MHz，16位数据有效位，时钟线和数据线都采用LVDS差分线形式，能够有效提高信号的抗干扰性。无线传输模块可采用WIFI模块或蓝牙模块，WIFI模块采用Marvell公司的88w8686芯片，适用于IEEE802.11a/g/b标准，低功耗、低电压且集成度高，最高传输速率可达54Mb/s；蓝牙模块采用HC-05，可以方便地根据指令改变模块的主从性，并且通讯距离可达20m。无线网络模块可采用GPRS或3G网络，集成于移动终端上。 Among them, the processor adopts Marvell's PXA322, the operating frequency can reach 624MHz, and integrates the memory unit controller, clock and power controller, SPI bus controller and so on. The temperature sensor adopts the DS18B20 model, the measurement temperature range is -55°C-+125°C, and the inherent temperature measurement resolution is 0.1°C. The PH value sensor uses a PH composite electrode to determine the ion activity to be measured by measuring the electromotive force. The conductivity sensor generates a high-stability sine wave signal and applies it to the electrode. The current flowing through the electrode is proportional to the conductivity of the solution to be measured, and then the current is converted into a voltage signal by a high-impedance operational amplifier for sampling. Dissolved oxygen sensor: By applying a voltage across a chamber filled with electrolyte closed by a selective membrane, the oxygen entering the chamber is ionized on the cathode, releasing electrons to form a current, and the amount of oxygen passing through the membrane is the same as that in water The amount of dissolved oxygen is proportional to the magnitude of the detection current (also converted into a voltage signal by the impedance operational amplifier for sampling) to obtain the content of dissolved oxygen. The ammonia nitrogen sensor adopts the ammonia gas sensitive electrode method. In an environment with a pH value greater than 11, the ammonium ion is transformed into ammonia, and the ammonia is transferred through the hydrophobic membrane of the ammonia sensitive electrode, resulting in a change in the electromotive force of the ammonia sensitive electrode. The instrument is measured according to the change in electromotive force concentration of ammonia nitrogen. The A/D converter adopts LTC2208, the sampling frequency can reach 130MHz, 16 valid data bits, and the clock line and data line are all in the form of LVDS differential line, which can effectively improve the anti-interference of the signal. The wireless transmission module can use WIFI module or Bluetooth module. The WIFI module adopts Marvell's 88w8686 chip, which is suitable for IEEE802.11a/g/b standards, low power consumption, low voltage and high integration, and the maximum transmission rate can reach 54Mb/s ;The Bluetooth module adopts HC-05, which can easily change the master-slave of the module according to the command, and the communication distance can reach 20m. The wireless network module can adopt GPRS or 3G network and be integrated on the mobile terminal.
移动终端将通过无线网络模块接收的数据传输到微处理器，显示器和存储器，无线网络模块为微处理器的外围接口，可以根据用户要求进行数据显示、存储和上传到监测中心。其中，存储器还负责存储数据处理功能的数据处理软件程序。其中，移动终端可以采用现有的基于Android系统的智能手机、基于ios系统的苹果系列移动电子产品，同时，还可采用独立制作的智能终端。 The mobile terminal transmits the data received through the wireless network module to the microprocessor, display and memory. The wireless network module is the peripheral interface of the microprocessor, which can display, store and upload data to the monitoring center according to user requirements. Wherein, the memory is also responsible for storing data processing software programs for data processing functions. Among them, the mobile terminal can adopt the existing smart phone based on the Android system, the Apple series mobile electronic products based on the ios system, and at the same time, an independently produced intelligent terminal can also be used.
在正常工作时，通过智能数据采集模块能够实时检测水质的各项指标，由于智能数据采集模块采用独立的封装防水结构，当需要检测温度时，只需要将温度智能数据采集模块开关打开，放入需要检测的水中，通过智能数据采集模块中含有的无线传输模块将温度传感器检测的数据发送给移动终端，利用移动终端包括的微处理器将数据处理、分析，在微处理器中安装有数据处理软件，采用Ec1ipse开发，利用JAVA语言编写，将采集的数据绘制成相应的曲线图，并可根据需要选择上传到监测中心。 During normal operation, various indicators of water quality can be detected in real time through the intelligent data acquisition module. Since the intelligent data acquisition module adopts an independent packaged waterproof structure, when the temperature needs to be detected, it is only necessary to turn on the switch of the temperature intelligent data acquisition module and put it in In the water that needs to be detected, the data detected by the temperature sensor is sent to the mobile terminal through the wireless transmission module contained in the intelligent data acquisition module, and the microprocessor included in the mobile terminal is used to process and analyze the data. The software is developed by Eclipse and written in JAVA language, which draws the collected data into corresponding curves, and can choose to upload to the monitoring center according to the needs.
由于水质监测有时需要检测多种指标，所以，只需要将相应的智能数据采集模块放入水中，通过移动终端分析、处理，就可以得出每一项指标的情况，可以方便工作人员查看，清晰，容易理解。 Since water quality monitoring sometimes needs to detect multiple indicators, it is only necessary to put the corresponding intelligent data acquisition module into the water, and through the analysis and processing of the mobile terminal, the situation of each indicator can be obtained, which is convenient for the staff to view and clearly , easy to understand.
