Description
技术领域technical field

背景技术Background technique
粉尘，是指悬浮在空气中的固体微粒。大气中粉尘的存在是保持地球温度的主要原因之一，但是大气中过多或过少的粉尘将对环境产生不利影响，例如，生产性粉尘是诱发多种疾病的主要原因，生产车间内粉尘浓度过高有可能发生粉尘爆炸等，因此对于环境中粉尘的检测显得尤为重要。Dust refers to solid particles suspended in the air. The existence of dust in the atmosphere is one of the main reasons for maintaining the temperature of the earth, but too much or too little dust in the atmosphere will have adverse effects on the environment. For example, productive dust is the main cause of many diseases, and dust in the production workshop If the concentration is too high, dust explosion may occur, so the detection of dust in the environment is particularly important.

According to different working principles, it can be divided into on-site filter sampling, ground laboratory weighing analysis, samplers for calculating dust concentration values, and those based on the principle of laser scattering. Dust concentration dust meter. However, this kind of sampler has many manual operation steps in actual application, which is more complicated, and the dust detector uses red light with long light wavelength and strong penetrating ability. The sensitivity of dust concentration changes is not high enough, and these two detection technologies cannot continuously monitor the dust concentration in the environment, except that they must work with human participation.
正是鉴于以上原因，本发明的发明目的就是克服现有粉尘监测报警装置不能在无人环境下正常工作和存贮查询历史被测数据，以及远距离感知环境中浓度超标的提示报警信息的问题。It is in view of the above reasons that the purpose of the present invention is to overcome the problems that the existing dust monitoring and alarm device cannot work normally in an unmanned environment, store and query historical measured data, as well as prompt alarm information for long-distance perception of excessive concentrations in the environment. .

提示值设定模块，用于设定提示设定值；The prompt value setting module is used to set the prompt set value;
通信模块，用于通过无线将当前粉尘浓度发送给远程终端。A communication module for wirelessly sending the current dust concentration to a remote terminal.
在一些具体实施例中，基于光电传感器的粉尘检测系统主要由：电源、粉尘探测模块、控制电路、控制程序、设置按钮、报警提示灯、液晶显示屏、串口通信构成，外加手机或者PC端的网络测试助手。它的主要零件控制电路是STC89C52单片机、串口通信是ESP8622WIFI模块、液晶显示是LCD1602模块均由市场选用。它的控制程序， 主要有：端口定义、延时函数、ADC0832采集函数、串口发送函数、串口中断服务函数、中值滤波算法、定时器初始化函数、Timer0中断服务函数、按键检测函数、报警函数、延时函数、显示屏LCD1602读写函数、串口发送函数、wifi初始化函数、以及主函数。In some specific embodiments, the dust detection system based on the photoelectric sensor is mainly composed of: a power supply, a dust detection module, a control circuit, a control program, a setting button, an alarm light, a liquid crystal display screen, a serial port communication, and a network on the mobile phone or PC. Test Assistant. Its main parts control circuit is STC89C52 microcontroller, serial communication is ESP8622WIFI module, and liquid crystal display is LCD1602 module, all of which are selected by the market. Its control program mainly includes: port definition, delay function, ADC0832 acquisition function, serial port sending function, serial port interrupt service function, median filter algorithm, timer initialization function, Timer0 interrupt service function, key detection function, alarm function, Delay function, display LCD1602 read and write function, serial port sending function, wifi initialization function, and main function.
而在工作原理方面是这样的：当该装置正常工作时，首先，基于光散射原理制成的粉尘探测模块能有效测得被测环境中粉尘浓度的变化，并且会输出一个模拟电压信号。其次，输出模拟信号会被ADC0832芯片构成的模数转换电路转换成数字信号，再传输给单片机的控制中心。下一步，单片机根据控制程序和输入信号会输出粉尘浓度的测定值既可以通过LCD1602显示屏现场显示，也可以通过WIFI模块构成的串口通信发送到手机或者PC端的网络测试助手显示。The working principle is as follows: when the device works normally, firstly, the dust detection module based on the light scattering principle can effectively measure the change of dust concentration in the measured environment, and output an analog voltage signal. Secondly, the output analog signal will be converted into a digital signal by the analog-to-digital conversion circuit composed of the ADC0832 chip, and then transmitted to the control center of the single-chip microcomputer. Next, the single-chip microcomputer will output the measured value of dust concentration according to the control program and input signal, which can be displayed on the LCD1602 display screen or sent to the network test assistant on the mobile phone or PC through the serial communication formed by the WIFI module for display.
最后便是设置及超标报警，根据被测环境中报警提示值的需求，刚开始会在程序里面设定一个数值，当被测浓度未达到报警值的一半时，会有一个绿灯亮，给出低浓度信号；而当被测浓度超过报警值的一半，但未到报警值时，绿灯熄灭，黄灯亮，给出一个提示信号；最后，当被测浓度超过报警值时，黄灯熄灭，红灯亮起，同时蜂鸣器开始响，给出报警信号。The last step is to set and exceed the alarm value. According to the needs of the alarm prompt value in the measured environment, a value will be set in the program at the beginning. When the measured concentration does not reach half of the alarm value, there will be a green light on, giving Low concentration signal; and when the measured concentration exceeds half of the alarm value, but does not reach the alarm value, the green light is off and the yellow light is on, giving a prompt signal; finally, when the measured concentration exceeds the alarm value, the yellow light is off and the red light is off. The light is on, and the buzzer starts to sound at the same time, giving an alarm signal.
因此，根据工作原理可知，整个装置的内部电路连接的主要关系是这样的：设有一个总开关位于电源模块的起始端，电源模块可用一根5V/1A的适配器与220V的电压源连接，而后电压模块与探测、数模转换、控制、程序下载、显示、设置报警模块连接并提供5V电能，而与AMS1117-3.3芯片连接后为串口通信模块提供3.3V电能；各个模块除了与电源端口的连接外，STC89C52单片机作为控制中心与各个模块都有相应的连接，此外，粉尘探测模块的输出端与ADC0832芯片的输入端连接，而ADC0832芯片的输出端与单片机连用；并且，因为串口通信模块采用的是现有的ESP8622WIFI，在应用中需要自己根据实际情况做调试，所以程序下载电路还与串口通信模块连接。Therefore, according to the working principle, the main relationship of the internal circuit connection of the whole device is as follows: a main switch is located at the starting end of the power module, and the power module can be connected with a 5V/1A adapter to a 220V voltage source, and then The voltage module is connected to the detection, digital-to-analog conversion, control, program download, display, and alarm setting modules and provides 5V power, and is connected to the AMS1117-3.3 chip to provide 3.3V power to the serial communication module; each module is connected to the power port except for the connection. In addition, the STC89C52 single-chip microcomputer as the control center has corresponding connections with each module. In addition, the output end of the dust detection module is connected with the input end of the ADC0832 chip, and the output end of the ADC0832 chip is connected with the single-chip microcomputer; It is the existing ESP8622WIFI, which needs to be debugged according to the actual situation in the application, so the program download circuit is also connected with the serial communication module.
粉尘探测模块基于光的散射原理制成，利用绿光弱与红光的穿透能力（绿光波长495~570nm；红光波长620~750nm)，更利于散射效应。The dust detection module is made based on the principle of light scattering, using the weak green light and the penetration ability of red light (green light wavelength 495~570nm; red light wavelength 620~750nm), which is more conducive to the scattering effect.
通信模块可以在半径为300米的距离内连接WIFI并实现探测数据的传输，而后直接可以用网络测试助手软件在手机或者PC端接收数据，由此可以适用于无人工厂等环境下检测粉尘浓度。The communication module can connect to WIFI within a radius of 300 meters and realize the transmission of detection data, and then directly use the network test assistant software to receive data on the mobile phone or PC, which can be applied to the detection of dust concentration in unmanned factories and other environments. .
显示模块不仅可以利用LCD1602液晶显示屏显示的数据现场实时显示粉尘浓度，而且可以在手机或者PC端直接读取和存贮数据，这样更利于数据的查询和分析。The display module can not only use the data displayed on the LCD1602 liquid crystal display to display the dust concentration in real time, but also directly read and store the data on the mobile phone or PC, which is more conducive to data query and analysis.
控制程序设定粉尘浓度提示值和报警值，也可以通过开关按钮设置粉尘浓度提示值和报警值；并且既可以通过三个不同颜色灯的发光状态，现场实时感知环境中的粉尘浓度，也可以通过手机或者PC端的数据准确掌握环境中粉尘浓度是否超标。The control program sets the dust concentration prompt value and alarm value, and can also set the dust concentration prompt value and alarm value through the switch button; and can sense the dust concentration in the environment in real time through the lighting status of three different color lights, or Accurately grasp whether the dust concentration in the environment exceeds the standard through the data on the mobile phone or PC.
