Fig. 2 is a schematic flowchart of an initialization configuration of the environment detection control apparatus 1000 according to an embodiment of the present invention. Specifically, in step S101, the internal components of the environment detection control apparatus 1000 are initialized, for example, the storage device (SPI _ FLASH) operating the serial interface is initialized, the detection components in the environment detection module 100, such as the temperature and humidity detection component 110, the illumination detection component 120, and the air quality detection component 130, the WI-FI network distribution component 310, such as the ESP8266 module, and the internal Real Time Clock (RTC) of the control module 500 are initialized, and the like. In step S102, it is determined whether a word stock needs to be configured, and if so, the process proceeds to step S103, where a word stock file in a secure digital card (SD card) is read and downloaded to the SPI _ FLASH, and if not, the process proceeds to step S104, where a task to be executed by the environment detection control apparatus 1000 is created. The task is, for example, task one: the function key is used for configuring WI-FI; and a second task: updating the data once per hour; and task three: and (5) infrared detection display. In step S105, the environment detection control apparatus 1000 performs autonomous scheduling on the created task.
Specifically, in this embodiment, the task is to perform WI-FI network distribution by the environment detection control apparatus 1000. Specifically referring to fig. 3, the environment detection control apparatus 1000 implements WI-FI network distribution by using an ESP8266 chip and upper computer software, which runs on a terminal device such as a mobile phone. After the WI-FI distribution network is successful, the environment detection control device can be connected with an external weather website at regular time, weather and environment data of outdoor three days in the future can be acquired according to user requirements, and the current Beijing time can be acquired. The acquired data can be displayed by the LED after being analyzed by the control module 500 running embedded software, so as to be provided to the user.
In step S201, the environment detection control apparatus 1000 starts an intelligent distribution network mode. In an embodiment, when the environment detection control device 1000 is in a working state, the environment detection control device 1000 can be started to be in an intelligent distribution network mode by pressing a key 2 times.
In step S202, the environment detection control apparatus 1000 is powered on again, because parameters such as the WI-FI password are written into the environment detection control apparatus 1000 after the intelligent distribution network is powered on again, and the parameters can be read normally only after the intelligent distribution network is powered on again.
In step S203, the control module 500 of the environment detection control apparatus 1000 transmits a command (AT command) transmitted from the terminal device or the data terminal device to the terminal adapter or the data circuit terminal device, and places the ESP8266 chip in a User Datagram Protocol (UDP) listening state.
In step S204, the mobile WI-FI connects to the Access Point (AP) to be configured.
In step S205, the upper computer software of the mobile phone is opened, and the software automatically scans the AP, obtains a Service Set Identifier (SSID) of the WI-FI, and inputs a WI-FI password.
In step S206, when the configuration button of the software is clicked, the software packages and encrypts the SSID and the password of the WI-FI and transmits the SSID and the password in a UDP broadcast manner.
In step S207, the ESP8266 chip monitors the UDP broadcast packet, and the control module 500 parses out the SSID and the password of the WI-FI for configuration.
In step S208, after configuration is successful, information is fed back to the upper computer software to complete the intelligent distribution network.
In this embodiment, the second task is to update the data of the indoor and outdoor environmental conditions every week by reading the data of the indoor environmental conditions of the temperature and humidity sensor, the illumination sensor, and the air quality sensor in the environment detection module 100 and the data of the outdoor environmental conditions obtained by the ESP8266 chip in this embodiment through the external WI-FI connection. In this embodiment, the temperature and humidity sensor, the light sensor, and the gas sensor are connected to the control module 500 through a serial transmission bus (I2C) interface, a climbing dust sensor, and an ESP8266 chip through an asynchronous receiver transmitter (UART) interface, so as to transmit the received environmental data to the control module 500 for processing. In some embodiments, the frequency of data updates may be set according to the user's habits.
In the present embodiment, task three is to perform infrared detection display according to the detected presence of the user. Referring to fig. 4, in step S301, it is determined whether the infrared detection is awakened. If the wake-up is performed, the process proceeds to step S302, and if the wake-up is not performed, the task three is ended. Specifically, when a user is in a detection area range of an infrared sensor, such as a passive infrared detector (PIR), on the environment detection control device, the infrared sensor can detect an infrared signal, and then the infrared sensor converts the detected infrared signal into an electrical signal through analog-to-digital conversion, and sends the electrical signal to a pin of the main control chip as a high-level pulse signal, and the control module 500 wakes up the infrared detection after detecting the signal. In this embodiment, the pin of the main control chip is a General Purpose Input and Output (GPIO) pin. The main control chip is not limited to the main control chip of the raspberry pi 510, but may be an MCU.
Step S302, after the infrared detection is waken up, a PIR wake-up flag is set, so that the control module 500 is switched from the sleep mode to the wake-up mode. Meanwhile, a real-time clock (RTC) inside the main control chip is turned off to stop performing other tasks, such as data updating of task two, so as to prevent background data confusion.
Step S303, determine whether the user exists. In order to prevent the false triggering of the infrared detection display, in the wake-up mode, only when the main control chip continuously detects the high-level pulse signal within the preset time, it indicates that the user is looking over the weather. The preset time can be set according to the needs of the user, for example, 5 seconds. The control module 500 continuously detects the high-level pulse signal within the preset time period, which is equivalent to detecting the presence of the user. If the control module 500 detects the presence of the user, the process proceeds to step S304.
In step S304, a system display mode is obtained, that is, after the control module 500 detects the presence of the user, the display module 400 is awakened to be displayed on the LED display screen for the user to view.
In steps S305 to S312, after the user selects the mode 1, the environment detection control device first displays the indoor environment condition and the time data; and after the first time delay, switching and displaying the outdoor environment condition and the time data. In one embodiment, the indoor environmental conditions include temperature, humidity, illumination intensity, and air quality, and the outdoor environmental conditions include weather and air quality. After the user selects the mode 2, firstly displaying the outdoor environment condition and the time data; and after the second time delay, switching and displaying the indoor environment condition and the time data. The selection of the mode and the delay time of data switching can be set according to the use habits of users.
In step S313, the environment detection control device starts the RTC, clears the PIR wake-up flag, and then enters the low power consumption state, and task three ends.
Task three can be performed by displaying the data of the indoor environmental condition and the data of the outdoor environmental condition when the presence of the user is detected, and not displaying the data of the indoor environmental condition and the data of the outdoor environmental condition when the presence of the user is not detected. This operation can control the energy saving operation of the environment detection control apparatus 1000.
Fig. 5 is a schematic flow chart of autonomous learning of the environment detection control apparatus 1000 according to an embodiment of the present invention. Specifically, in step S401, a large amount of data of daily habits of multiple persons, such as a point of departure and work, a point of weather, and the like, is collected.
In step S402, an algorithm model with a relatively high accuracy is trained by using a machine learning algorithm according to the collected data.
In step S403, the algorithm model is embedded in the main control chip of the control module 500.
In step S404, when the user uses the algorithm, the control module 500 automatically collects data into the algorithm model every day according to the actual usage habit of the user.
In step S405, after a certain amount of user data is collected, the algorithm model of the main control chip of the control module 500 may predict the data of the user every day, so as to adjust the device controlled by the environment detection control apparatus 1000 according to the habit information of the user. Specifically, the environment detection control apparatus 1000 controls the external device through bluetooth wireless communication. Examples of the external device include an air conditioner, a lighting device, and an air cleaner having a bluetooth wireless communication function.
For example, the user may check the weather condition before going to work eight times a day in the morning, and the environment detection control device 1000 records the time when the user checks the weather condition every day and records the time as the work time of the user, thereby controlling the air conditioner and the lighting device to be turned off at eight times a day. The air conditioner and the lighting device may be connected to the environment detection control device 1000 through bluetooth.
The environment detection control device 1000 can adjust the ambient light, humidity, temperature and the like according to different habits of the user by acquiring user data and autonomously learning, and can control the energy-saving operation of external equipment related to the environment detection control device, so that the family life of the user is more energy-saving and environment-friendly, and the environment detection control device is convenient and comfortable, and the user experiences new experience brought by the intelligent household equipment.

Fig. 7 is a fitting curve graph of the indoor temperature and the deviation provided by the embodiment of the present invention. The data acquired by the temperature and humidity detecting element 110 is affected by the heat generated by the circuit board, and cannot completely reflect the indoor temperature condition, so that the final correct data can be obtained only by compensating according to the relationship between different circuit board temperatures and the ambient temperature through actual tests. Referring to fig. 1, 6 and 7, specifically, in step S501, different ambient temperature values, for example, 10 ℃, 15 ℃, 20 ℃, 25 ℃ and 30 ℃, are collected by using an external precise temperature measuring instrument. In step S502, the indoor temperature at the above-described ambient temperature, for example, 9.8 ℃, 15.2 ℃, 20.3 ℃, 24.7 ℃, 30.5 ℃ is acquired by the temperature/humidity detection element 110 of the environment detection control device 1000. In step S503, the temperature compensation unit 111 in the temperature/humidity detection element 110 obtains a deviation value of-0.2 ℃, -0.3 ℃, 0.3 ℃, -0.5 ℃ from the results obtained in step S501 and step S502. In step S504, the temperature compensation unit 111 fits the indoor temperature and the deviation value to obtain a curve y ═ ax of the deviation value e between the actual indoor temperature and the measured indoor temperature2+ bx + c, as shown in FIG. 7. In step S505, the temperature compensation unit may obtain a deviation value e0 ═ ax0 when the indoor temperature is x0 degrees according to the curve obtained by fitting in step S5042+ bx0+ c, and finally obtaining the compensated temperature value w ═ x0+ e 0. In step S506, the temperature compensation unit 111 sends the obtained compensated temperature value w to the control module 500 for subsequent processing.
