Description

Real-time monitoring system and monitoring method for air particle concentration and fluorescence intensity data

technical field

The invention belongs to the technical field of particle concentration and fluorescence intensity data detection, in particular to a system and method for real-time measurement and monitoring of air particle concentration and fluorescence intensity data.

Background technique

In industries such as medicine, electronics, precision machinery, color tube manufacturing, and microorganisms, there are high requirements for the cleanliness of the air in the workshop. The cleanliness level of the clean workshop is often determined by the maximum number of particles allowed in the air per unit volume, that is, the number of particles concentration to measure.

In the prior art, a dust particle counter is used to measure the number of dust particles of various particle sizes in the air, wherein the subsequent processing circuit of the dust particle counter outputs the data of the number of dust particles of various particle sizes in the measured air, and then the LED is used to measure the number of dust particles in the air. The display screen shows the number of particles in a certain particle size channel in the dust particle number data. The dust particle counter switches multiple channels of various dust particle sizes through a particle size switching key (particle size key).

The dust particle data of the prior art gives the number of particles of different dust particle sizes, such as 0.3 μm, 0.5 μm, 0.7 μm, 1.0 μm, 2.0 μm, 5.0 μm, ..., wherein each particle size range is also called A particle size channel. Assuming that the total number of channels is N, N is a natural number, and n is the channel number of a certain channel, then the channel number n is a natural number from 1 to N. In this way, for example, when the particle diameter channel number n=1 is selected through the particle diameter key, the number of particles with a dust particle diameter of 0.3 μm will be displayed on the LED display; The screen displays the number of particles with a dust particle size of 0.5 μm; and so on. That is, in the prior art, the number of particles corresponding to the nth particle size channel is displayed on the LED display screen according to the order of the particle size channel number n.

It can be seen from this that the existing dust particle counter can only select one particle size channel every time the particle size button is pressed, and can only display the number of particles in this one particle size channel, and cannot monitor the particles of multiple particle size channels at the same time. Quantitative changes are monitored.

In addition, air monitors are also used to measure air quality. For example, in an air monitor, it divides the air quality into 0 to 250 different levels, and displays red, yellow, green, and blue according to different ranges. Four indicator lights, when the red light and blue light are on, it will alarm. At the same time, it also, for example, divides volatile organic gases into 0 to 99 different grades; divides harmful gases into 0 to 99 different grades, and displays red, yellow and green indicators in different ranges. , when the display light is red, it will alarm.

It can be seen that the existing air monitors can only classify and alarm the components in the air, but cannot monitor the number of particles in the air with high precision, and cannot accurately observe the changes in the number of particles and fluorescence intensity data in each channel in the air.

Fluorescence technology can be used to identify fluorescent substances, each fluorescent substance has its specific excitation spectrum and emission spectrum.

Fix the emission wavelength, and record the relative intensity of fluorescence emitted by the sample at different wavelengths, that is, the excitation spectrum. The basis for determining the appropriate excitation wavelength of the fluorescent substance is to reflect the situation after the substance is excited, and to reflect the effect of the substance on The response to external excitation light reflects the relationship between its own radiation wavelength and the excitation wavelength.

Fix the excitation wavelength, record the relative intensity of the fluorescence emitted at different wavelengths, that is, the emission spectrum, the spectrum directly produced by the object’s light emission is called the emission spectrum, and the emission spectrum determines the basis for the detection wavelength of the fluorescent substance.

Fluorescence intensity is the number of light quanta emitted by a fluorescent substance. The fluorescence efficiency of a fluorescent substance determines its fluorescence intensity, which also determines the sensitivity of fluorescent substance detection. Therefore, the fluorescence intensity can be used to detect fluorescent substances. Under conditions such as low concentration, the sample concentration (that is, the number of air particles) has a linear relationship with the fluorescence intensity.

To sum up, the existing technology cannot monitor and display air particle concentration or fluorescence intensity data in real time, especially both at the same time, so it cannot meet people's increasing requirements for air quality.

Fig. 1 is an architecture diagram of a real-time monitoring system for air particle concentration and fluorescence intensity data according to an embodiment of the present invention. As shown in Figure 1, the monitoring system of the present invention includes a monitoring terminal 1 and a detection device 2, the detection device 2 is also called a lower computer, which can output the detection data of air particle concentration and fluorescence intensity data in real time according to control instructions. The monitoring terminal 1 is also called the upper computer, which is used to send control instructions to the detection device 2, and receive the detection data output by the detection device 2, and display the detection data in real time after processing the detection data.

According to the present invention, the monitoring terminal 1 and the detection device 2 can be connected in a wired or wireless manner, and various existing communication interfaces and protocols can be used, such as serial port, LAN, Bluetooth, WiFi, USB, etc.

According to another embodiment of the present invention, as shown in Figure 2, the real-time monitoring system of the present invention may also include a plurality of detection devices 2, 2', 2", which can be connected to the monitoring terminal 1 by wired or wireless means Thus, each detection device 2 can be placed in different air environments, for example, in multiple different sections of a city, so as to detect the air quality of multiple sections in real time.

According to the present invention, the detection data output by the detection device 2 is digitized and coded data. That is to say, the detection device 2 encodes the data of the number of air particles and the fluorescence intensity detected by it to generate a data stream for output. Moreover, the detection device 2 sends the coded detection data at a certain time interval, which may be fixed at 0.5 second, 1 second, 3 seconds, etc., or may be manually set according to actual needs.

FIG. 3 is a block diagram of an embodiment of the monitoring terminal 1 of the present invention. As shown in Figure 3, the monitoring terminal 1 of the present invention includes a main control module 10, an input and output module 11, a data analysis module 12, a particle number maximum value search module 13, a fluorescence intensity maximum value search module 14, a drawing module 15 and a display module 16.

The input and output module 11 is used for inputting and outputting data. In this embodiment of the present invention, it is used for sending control commands from the main control module 10 to the detection device 2 and receiving detection data sent by the detection device 2 . As mentioned above, the detection data of the present invention is a data stream composed of encoded air particle data and fluorescence intensity data.

The data analysis module 12 is used for analyzing the detection data received by the input and output module 11, and extracting air particle number data and fluorescence intensity data respectively therefrom. Since the detection data is encoded data, the data parsing module 12 performs decoding according to the encoding format of the data. For example, in a specific implementation manner, the detection data is multi-channel detection data, and the multi-channel detection data is a data chain of 6764 data starting with 255,1 and ending with 255,2, if Judging that the beginning of a group of 6764 data links is 255, 1, and the end is 255, 2, then the multi-channel detection data is valid data, and the multi-channel detection data can be analyzed to obtain the air particle number data and Fluorescence intensity data. For example, the analysis method of the data analysis module 12 is as follows: by analyzing the fixed position of each data link, the air particle number data and fluorescence intensity data can be obtained, such as reading the air particle data 11FF, which is in the 512th part of the data link , the data at position 513, the high-order data 1100 stored at position 512, the low-order data FF stored at position 513, and the high-order and low-order data are added to obtain 11FF data, which is the obtained air particle data 11FF.

The air particle data coordinate data refers to the data used to draw the coordinate axis of the air particle number distribution graph, including abscissa data and ordinate data. The abscissa indicates the air particle size of each air particle size channel, and the ordinate indicates the number of air particles. Generally speaking, the number N of passages detected by the detection device 2 is fixed, so the scale value of the abscissa is usually fixed, and the value of the number of particles in each passage detected may exist due to the detected air environment. There is a big difference, so it is necessary to set a suitable coordinate value for the vertical axis. According to the present invention, the drawing module 15 sets the scale value of the ordinate according to the particle number maximum value obtained by the particle number maximum value search module 13, for example, if the particle number maximum value found by the particle number maximum value search module 13 is 867, Then, the maximum number of particles is rounded up to 10 to obtain 870, and the drawing module 15 sets 870 as the maximum scale value of the ordinate.

Fluorescence intensity data coordinate data refers to the data used to draw the coordinate axis of the fluorescence intensity data distribution graph, including abscissa data and ordinate data, the abscissa indicates the channel of each fluorescence intensity, and the ordinate indicates the number of particles corresponding to the fluorescence intensity channel . Similarly, the scale value of the abscissa is usually fixed, and the detected fluorescence intensity data values of each channel may vary greatly due to the detected air environment, so it is necessary to set an appropriate coordinate value for the ordinate. According to the present invention, the plotting module 15 sets the scale value of the ordinate according to the maximum value of fluorescence intensity obtained by the maximum value of fluorescence intensity search module 14, for example, if the maximum value of the number of particles found by the maximum value of fluorescence intensity search module 14 is 867, Then, the maximum number of particles is rounded up to 10 to obtain 870, and the drawing module 15 sets 870 as the maximum scale value of the ordinate of the fluorescence intensity data.

The multi-channel distribution data of the number of air particles and the multi-channel distribution data of the fluorescence intensity data are the data obtained by graphically converting the air particle number data and the fluorescence intensity data analyzed by the data analysis module 12, for example, the air particle number of each channel can be The data and the fluorescence intensity data are expressed as a columnar graph or a line graph, etc., and the multi-channel distribution data of the number of air particles and the multi-channel distribution data of the fluorescence intensity data are the data used to draw the graph.

The particle number array is also an array of particle numbers containing 52 particle sizes. The scale of the x-direction coordinate of the air particle number two-dimensional coordinate system means the particle size of the 52-dimensional channel. When printing and drawing the scale of the x-direction coordinates of the two-dimensional coordinate system of air particle concentration, only 10 channel particle size coordinate values are taken to indicate the abscissa distribution of particle size. The x-direction coordinate scale values of the particle sizes of these ten channels are 0.5, 0.7, 1, 2, 3, 4, 5, 6, 10, and 15, respectively. The number of channels in the x-direction coordinates of the two-dimensional coordinate system of the fluorescence intensity data is 65, and the scale value of the x-direction coordinates is printed every 5 channels, that is, the scale values of 13 channels are displayed on the x-direction coordinates of the two-dimensional coordinate system of the fluorescence intensity data . The number of channels of the scale on the x-direction coordinates is not limited to 65, and the number of channels can be selected according to needs. Figure 4 shows the two-dimensional coordinate system of air particles. The abscissa indicates the corresponding particle size. For example, the particle size of the abscissa is 4.696 μm, and the number of the ordinate corresponding to the abscissa is the particle with a particle size of 4.696 μm. the number of particles.
