为使对本发明的结构特征及所达成的功效有更进一步的了解与认识，用以较佳的实施例及附图配合详细的说明，说明如下：In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:
如图1所示，本发明所述的一种基于物联网和蓝牙技术的工业环境空气质量实时监测系统，包括Android手机3、蓝牙模块4、粉尘传感器2和Arduino主控板1。Arduino主控板1用于整体的计算和控制，粉尘传感器2用于采集现场的空气质量。粉尘传感器2的型号可以为DSM501，用于PM2.5的数据采集，也可以为其他指标的专用采集工具。蓝牙模块4用于使用蓝牙技术对外进行数据传输，其型号可以为HC-06。粉尘传感器2的数据输出端与Arduino主控板1的数据输入端相连，粉尘传感器2将其采集到的监测数据传送给Arduino主控板1。蓝牙模块4接在Arduino主控板1的通信接口上，给Arduino主控板1向外界传送数据信息。蓝牙模块4与Android手机3进行蓝牙无线连接，将数据信息展示给用户。As shown in Figure 1, a kind of industrial environment air quality real-time monitoring system based on the Internet of Things and Bluetooth technology of the present invention includes an Android mobile phone 3, a Bluetooth module 4, a dust sensor 2 and an Arduino main control board 1. Arduino main control board 1 is used for overall calculation and control, and dust sensor 2 is used to collect the air quality of the site. The model of the dust sensor 2 can be DSM501, which is used for PM2.5 data collection, or it can be a special collection tool for other indicators. The bluetooth module 4 is used for external data transmission using bluetooth technology, and its model can be HC-06. The data output end of the dust sensor 2 is connected to the data input end of the Arduino main control board 1 , and the dust sensor 2 transmits the monitoring data collected by it to the Arduino main control board 1 . The Bluetooth module 4 is connected to the communication interface of the Arduino main control board 1, and transmits data information to the outside world for the Arduino main control board 1. The bluetooth module 4 carries out the bluetooth wireless connection with the Android mobile phone 3, and displays the data information to the user.
如图2所示，本发明提供一种基于物联网和蓝牙技术的工业环境空气质量实时监测系统的控制方法，包括以下步骤：As shown in Fig. 2, the present invention provides a kind of control method of the industrial environment air quality real-time monitoring system based on Internet of Things and Bluetooth technology, comprising the following steps:
第一步，粉尘数据的获取，通过粉尘传感器2实时采集当前外部环境中的粉尘污染参数，并传送给Arduino主控板1。粉尘传感器2以秒为单位，在外部环境中实时采集污染指数，如粉尘传感器2为DSM501时，则实时采集PM2.5的含量，通过自身的接口传送给Arduino主控板1，以供Arduino主控板1进行计算比较。The first step is the acquisition of dust data. The dust pollution parameters in the current external environment are collected in real time through the dust sensor 2 and transmitted to the Arduino main control board 1 . The dust sensor 2 collects the pollution index in real time in the external environment in seconds. For example, when the dust sensor 2 is DSM501, it collects the PM2.5 content in real time and transmits it to the Arduino main control board 1 through its own interface for the Arduino main control board. Control board 1 performs calculation and comparison.
第二步，粉尘数据的计算，Arduino主控板1对获取到的实时粉尘数据进行统计和计算，并传送给蓝牙模块4。粉尘传感器2所传送的数据为每秒不断变化的数据，而网络传输速度无法达到以秒进行更新的程序，也就是说给用户所展示的数据无法直接从粉尘传感器2中获取就展示给客户，因此Arduino主控板1需要对所获取的数据进行处理和分析，如图3所示，其具体步骤如下：The second step is the calculation of dust data. The Arduino main control board 1 performs statistics and calculation on the acquired real-time dust data, and transmits it to the Bluetooth module 4 . The data transmitted by the dust sensor 2 is constantly changing data per second, and the network transmission speed cannot reach the program of updating in seconds, that is to say, the data displayed to the user cannot be directly obtained from the dust sensor 2 and then displayed to the customer. Therefore, Arduino main control board 1 needs to process and analyze the acquired data, as shown in Figure 3, the specific steps are as follows:
(1)Arduino主控板1设定当前时间为采集计算起始时间，采集时间为T，T＝30s。采集时间T的设置可以根据蓝牙传输速度来进行设定，采集时间越长，则采集精度越低；采集时间越短，虽采集精度越高，但其传输压力就越大，按蓝牙传输速率换算，T最好可以设置为30秒。(1) Arduino main control board 1 sets the current time as the start time of acquisition and calculation, and the acquisition time is T, where T=30s. The collection time T can be set according to the Bluetooth transmission speed. The longer the collection time, the lower the collection accuracy; the shorter the collection time, the higher the collection accuracy, but the greater the transmission pressure. Converted according to the Bluetooth transmission rate , T can best be set to 30 seconds.
(2)Arduino主控板1通过粉尘传感器2获取30秒内每秒的实时粉尘数据βi，共30个。(2) The Arduino main control board 1 acquires 30 real-time dust data β i per second within 30 seconds through the dust sensor 2 .
(3)Arduino主控板1计算平均污染值a，其计算公式如下：(3) Arduino main control board 1 calculates the average pollution value a, and its calculation formula is as follows:
其中βi为每秒的实时粉尘数据，对30个实时粉尘值进行平均计算后，得出平均污染值a。 Among them, β i is the real-time dust data per second, and the average pollution value a is obtained after the average calculation of 30 real-time dust values.
(4)Arduino主控板1向蓝牙模块4输出平均污染值a，并重置采集计算起始时间，以供下一个时间周期T平均污染值的输出。(4) The Arduino main control board 1 outputs the average pollution value a to the Bluetooth module 4, and resets the start time of collection and calculation for the output of the average pollution value in the next time period T.
第三步，建立蓝牙无线连接，Android手机3与蓝牙模块4建立蓝牙无线连接，以备数据发送使用。其具体步骤如下：The third step is to establish a Bluetooth wireless connection, and the Android mobile phone 3 establishes a Bluetooth wireless connection with the Bluetooth module 4 for data transmission. The specific steps are as follows:
(1)Android手机3开启手机蓝牙权限，Android手机3先查看自身是否已打开蓝牙连接，若未打开则将手机的蓝牙连接打开。(1) The Android mobile phone 3 turns on the bluetooth permission of the mobile phone. The Android mobile phone 3 first checks whether the bluetooth connection has been turned on by itself, and if it is not turned on, the bluetooth connection of the mobile phone is turned on.
(2)Android手机3搜索蓝牙设备，Android手机3对蓝牙范围内存在的蓝牙设备进行搜索，查找蓝牙模块4。(2) The Android mobile phone 3 searches for the Bluetooth device, and the Android mobile phone 3 searches for the Bluetooth device existing in the Bluetooth range to find the Bluetooth module 4 .
(3)Android手机3找到蓝牙模块4，注册BroadcastRceciver，将蓝牙模块4与Android手机3进行配对，获取配对信息，与蓝牙模块4建立无线连接。(3) The Android mobile phone 3 finds the Bluetooth module 4, registers BroadcastRceciver, pairs the Bluetooth module 4 with the Android mobile phone 3, obtains pairing information, and establishes a wireless connection with the Bluetooth module 4.
(4)Android手机3监听蓝牙模块4，若蓝牙模块4有数据外送，Android手机3则接收蓝牙模块4发送的粉尘数据。(4) The Android mobile phone 3 monitors the Bluetooth module 4 , and if the Bluetooth module 4 sends out data, the Android mobile phone 3 receives the dust data sent by the Bluetooth module 4 .
第四步，污染数据的展示，Android手机3接收蓝牙模块4发送的粉尘数据，在Android手机3给用户进行展示，随时地为不同用户提供工业环境空气质量的监测。The fourth step is the display of pollution data. The Android mobile phone 3 receives the dust data sent by the Bluetooth module 4, and displays it to the user on the Android mobile phone 3, providing different users with monitoring of the air quality of the industrial environment at any time.
