Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
图1是本发明提供的水体磷酸盐检测系统的结构示意图，如图1所示，本发明提供一种水体磷酸盐检测系统，包括：信号发生器1、外腔式量子级联激光器2、液体池3、离轴抛物面反射镜4、红外探测器9、示波器10和计算机11。Figure 1 is a structural schematic diagram of a water phosphate detection system provided by the present invention. As shown in Figure 1, the present invention provides a water phosphate detection system, including: a signal generator 1, an external cavity quantum cascade laser 2, a liquid pool 3, an off-axis parabolic reflector 4, an infrared detector 9, an oscilloscope 10 and a computer 11.
信号发生器1用于驱动外腔式量子级联激光器2发射出激光光束；液体池3用于透射激光光束至离轴抛物面反射镜4；液体池3盛放有待检测水体；离轴抛物面反射镜4用于将激光光束聚焦到红外探测器9的接收端；红外探测器9用于将接收到的激光光束传输给示波器10；示波器10用于实现显示激光光束的光强光谱，并将激光光束的光强光谱传输给计算机11；计算机11用于基于激光光束的光强光谱，得到待检测水体中磷酸盐的浓度。The signal generator 1 is used to drive the external cavity quantum cascade laser 2 to emit a laser beam; the liquid pool 3 is used to transmit the laser beam to the off-axis parabolic reflector 4; the liquid pool 3 contains the water body to be detected; the off-axis parabolic reflector 4 is used to focus the laser beam to the receiving end of the infrared detector 9; the infrared detector 9 is used to transmit the received laser beam to the oscilloscope 10; the oscilloscope 10 is used to display the light intensity spectrum of the laser beam, and transmit the light intensity spectrum of the laser beam to the computer 11; the computer 11 is used to obtain the concentration of phosphate in the water body to be detected based on the light intensity spectrum of the laser beam.
具体地，外腔式量子级联激光器（External Cavity Quantum Cascade Laser，EC-QCL）是超越FTIR的新型精细化测量技术。EC-QCL通过外置谐振腔的方式可以在室温条件下实现在几百个波数的快速连续谐调。EC-QCL既拥有传统FTIR的指纹特性，又具备激光光谱的优势，高光谱功率密度使其具备优秀的抗干扰能力，具有能摆脱参考背景测量、仅以原始光强数据用于模型建立的潜力。同时，EC-QCL具有小型化的优势，非常适合用于高灵敏度原位检测传感器的开发，目前EC-QCL已在多个领域进行了成功的应用，显示出巨大的应用潜力。Specifically, the External Cavity Quantum Cascade Laser (EC-QCL) is a new type of refined measurement technology that goes beyond FTIR. EC-QCL can achieve fast and continuous tuning of hundreds of wave numbers at room temperature through an external resonant cavity. EC-QCL has both the fingerprint characteristics of traditional FTIR and the advantages of laser spectroscopy. Its high spectral power density gives it excellent anti-interference ability and the potential to get rid of reference background measurements and use only raw light intensity data for model building. At the same time, EC-QCL has the advantage of miniaturization and is very suitable for the development of high-sensitivity in-situ detection sensors. EC-QCL has been successfully applied in many fields and shows great application potential.
信号发生器1的输出端与外腔式量子级联激光器2的输入端连接，以使信号发生器1能驱动外腔式量子级联激光器2发射出激光光束。The output end of the signal generator 1 is connected to the input end of the external cavity quantum cascade laser 2, so that the signal generator 1 can drive the external cavity quantum cascade laser 2 to emit a laser beam.
外腔式量子级联激光器2的输出端、液体池3以及离轴抛物面反射镜4处于同一光路上，以使外腔式量子级联激光器2发射出激光光束能够透射盛放有待检测水体的液体池3到达离轴抛物面反射镜4。激光光束透射盛放有待检测水体的液体池3后，激光光束将携带待检测水体的信息。The output end of the external cavity quantum cascade laser 2, the liquid pool 3 and the off-axis parabolic reflector 4 are on the same optical path, so that the laser beam emitted by the external cavity quantum cascade laser 2 can pass through the liquid pool 3 containing the water body to be detected to reach the off-axis parabolic reflector 4. After the laser beam passes through the liquid pool 3 containing the water body to be detected, the laser beam will carry the information of the water body to be detected.
离轴抛物面反射镜4与红外探测器9的接收端处于同一光路上，以使激光光束到达离轴抛物面反射镜4后，离轴抛物面反射镜4能够将激光光束聚焦到红外探测器9的接收端，让红外探测器9接收激光光束。The off-axis parabolic reflector 4 and the receiving end of the infrared detector 9 are on the same optical path, so that after the laser beam reaches the off-axis parabolic reflector 4, the off-axis parabolic reflector 4 can focus the laser beam to the receiving end of the infrared detector 9, allowing the infrared detector 9 to receive the laser beam.
红外探测器9的输出端与示波器10的第一端连接，示波器10的第二端与计算机11连接，以使红外探测器9将接收到的激光光束传输给示波器10，示波器10能够实现显示激光光束的光强光谱，并将激光光束的光强光谱传输给计算机11，计算机11能够基于激光光束的光强光谱，得到待检测水体中磷酸盐的浓度。The output end of the infrared detector 9 is connected to the first end of the oscilloscope 10, and the second end of the oscilloscope 10 is connected to the computer 11, so that the infrared detector 9 transmits the received laser light beam to the oscilloscope 10, and the oscilloscope 10 can display the light intensity spectrum of the laser beam and transmit the light intensity spectrum of the laser beam to the computer 11. The computer 11 can obtain the concentration of phosphate in the water body to be detected based on the light intensity spectrum of the laser beam.

在相关技术中使用的是双光路，一条光路用于采集参考背景，一条光路用于采集样品信息。相关技术中采用两条光路的主要原因是：光路所使用的光源能量较弱，而所处工作环境和仪器会对光谱数据产生一定的影响造成数据有效性降低，使用两条光路在采集数据时所面临的干扰因素是相同，因此将两条光路的光谱数据进行比值处理求取吸光度可以有效消除噪声对数据有效性的干扰。In the related art, dual optical paths are used, one optical path is used to collect reference background, and the other optical path is used to collect sample information. The main reason for using two optical paths in the related art is that the light source energy used in the optical path is weak, and the working environment and instruments will have a certain impact on the spectral data, resulting in reduced data validity. The interference factors faced when using two optical paths to collect data are the same, so the spectral data of the two optical paths are processed by ratio to obtain absorbance, which can effectively eliminate the interference of noise on data validity.
而本发明使用的是EC-QCL激光光源，其光源能量比常规光源能量高出几个或几十个数量级，原理上在工作期间是可以忽略环境或仪器自身对数据有效性的干扰，因此本发明使用的是一条光路，并且获取的数据可以经过简单的数据处理后直接用于建立光谱信号和浓度之间的线性关系。因此，相比于相关技术，本发明提供的水体磷酸盐检测系统结构更简单，更小型化。The present invention uses an EC-QCL laser light source, whose light source energy is several or dozens of orders of magnitude higher than that of a conventional light source. In principle, the interference of the environment or the instrument itself on the data validity can be ignored during operation. Therefore, the present invention uses a single optical path, and the acquired data can be directly used to establish a linear relationship between the spectral signal and the concentration after simple data processing. Therefore, compared with the related art, the water phosphate detection system provided by the present invention has a simpler structure and is more miniaturized.

在一些实施例中，液体池3的测量光程为100~150μm。In some embodiments, the measuring optical path of the liquid pool 3 is 100-150 μm.
具体地，在相关技术中测量光程为5m，由于光路的原因造成体积过大不利于小型化，在原位检测时存在一定困难。Specifically, in the related art, the measuring optical path is 5 m. Due to the optical path, the volume is too large, which is not conducive to miniaturization, and there are certain difficulties in in-situ detection.

After cleaning, the peristaltic pump 5 injects the clean water of the water body to be detected in the detection tank 6 into the liquid tank 3 to start detecting the phosphate in the water body to be detected.
在计算机11获取了激光光束的光强光谱之后，蠕动泵5再次将清水池7中的清水注入到液体池3内，以去除液体池3内残留的待检测水体，避免影响下一次的检测结果。After the computer 11 obtains the intensity spectrum of the laser beam, the peristaltic pump 5 injects the clean water in the clean water pool 7 into the liquid pool 3 again to remove the remaining water to be detected in the liquid pool 3 to avoid affecting the next detection result.
