Description

Technical Field

[0001] The utility model belongs to the field of sensor monitoring, and specifically relates to a multifunctional environment detection and alarm system based on a cloud platform. Background Art

[0002] Traditional environmental monitoring and alarm devices mainly rely on core technologies such as sensors to monitor environmental parameters such as air quality, water quality, noise, temperature and humidity in real time, and analyze data changes. Once an abnormal situation is found, the device will immediately alarm and send alarm information to relevant personnel through sound and light to ensure that environmental problems are responded to and handled in a timely manner. This technology not only improves the efficiency and accuracy of environmental monitoring, but also helps to reduce and prevent environmental pollution, providing a strong guarantee for the construction of ecological civilization.

[0003] However, since traditional environmental monitoring and alarm devices mainly rely on regular manual sampling and analysis, they lack real-time and continuity. These devices usually have relatively simple functions, mainly focusing on specific environmental parameters such as temperature, humidity or the concentration of certain specific pollutants, and lack modularity and scalability. In addition, these devices usually lack intelligent analysis and remote monitoring functions, making it difficult to integrate into the era of the Internet of Things and unable to meet diverse usage needs. In addition, the data recording and analysis of traditional environmental monitoring and alarm devices are usually inefficient and easily affected by human factors. Overall, traditional environmental monitoring and alarm devices have obvious deficiencies in real-time, intelligence and remote monitoring.

The device adopts a modular design, and each module has independent functions and can be freely combined and expanded according to user needs. At the same time, the device also integrates a variety of sensors and data processing technologies. Combined with China Mobile's Internet of Things open platform (Onenet cloud platform), it can monitor the temperature, humidity, gas concentration and other parameters in the environment in real time, while also providing users with real-time data monitoring, receiving alarm information and remote control equipment anytime and anywhere. This design greatly improves the reliability and ease of use of the device, allowing users to more conveniently obtain and process data. Summary of the invention

[0029] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The described specific embodiments are only used to explain the present invention and are not intended to limit the present invention.

[0030] like Figure 1 As shown, a multifunctional environment detection and alarm system based on the OneNET cloud platform includes an environment detection and alarm device 1, a client 2, and a OneNET cloud platform 3.

[0031] like Figure 2-3 As shown, the environment detection and alarm device 1 includes a host module and a slave module, so that the host can receive slave signals at other locations; the host module and the slave module are placed separately. The host module includes a host housing, and a host control unit 6, an OLED display screen 4, a host fill light 12 and a communication module 8 located inside the host housing; the OLED display screen 4, the host fill light 12 and the communication module 8 are all electrically connected to the host control unit 6. The host control unit 6 reads the data of the cloud platform 3 through the communication module 8 and displays it on the OLED display screen 4, and can actively control the brightness of the host fill light 12 through the applet of the client 2, and can also control the on and off of the host fill light 12 through the voice recognition function of the applet. The OLED display screen 4 is used to display the environmental data collected from the sensor unit of the slave module in real time, including temperature, humidity and harmful gas concentration (including various combustible gases and smoke).

[0032] The slave module includes a slave housing and a slave control unit 7, a communication module 8, a sensor unit and an alarm unit located inside the slave housing. The slave housing of the slave module is hung on the indoor wall or installed on the ceiling, and the distance from the lamp is preferably greater than 30 cm to avoid placing the sensor unit at the vent to avoid false alarms or delayed alarms. The sensor unit, the alarm unit and the communication module 8 in the slave module are all electrically connected to the slave control unit 7. The sensor unit uploads the detection data to the cloud platform 3 through the communication module 8, and turns on the alarm unit when the detection result is abnormal.

[0033] The communication module 8 is an ESP8266Wifi module, which is used for interactive communication between the host control unit 6 / slave control unit 7 and the cloud platform 3. It adopts an ultra-low power consumption UART-WIFI transparent transmission module. The ESP8266 chip equipped integrates a complete TCP / IP protocol stack and MCU, and the module adds necessary peripheral circuits, onboard antennas, etc. In addition, the communication module 8 adopts STA mode, accesses the wireless network as a wireless WIFI STA, realizes wireless (WIFI) data conversion and mutual transmission between the serial port and other devices, and adopts TCP client mode to connect the module to the server for data transmission. The communication module 8 is powered by the host control unit 6 / slave control unit 7 connected to each other.

[0034] The host control unit 6 / slave control unit 7 communicates with the OneNET cloud platform 3 through the communication module 8, and the communication protocol adopts the HTTP protocol. The client 2 uses the HTTP protocol to access the OneNET cloud platform data. In the OneNET cloud platform, devices are supported to report data using the HTTPS / HTTP2 protocol, with a fixed access address, access data specification and system return code design, which facilitates the mutual transmission and control of various data between devices and the cloud platform.

[0035] The host control unit 6 and the slave control unit 7 adopt the master-slave mode, and the development boards of the master and slave control units respectively select the stm32f103c8t6 minimum system board and the stm32f103rct6 mini development board. Among them, the stm32f103c8t6 minimum system board is an embedded development board. This chip is a high-performance, low-power Cortex-M3 core microcontroller with an operating frequency of 72Mhz and rich peripheral resources, such as multiple general timers, general serial interfaces, etc. The minimum system board is equipped with necessary power supply circuits and crystal oscillator circuits to ensure the normal operation of the chip. A rich pin interface is also provided on the board to facilitate users to connect external devices and expand functions.

[0036] The stm32f103rct6mini development board uses a high-performance ARM Cortex-M3 processor with rich peripheral interfaces and functions, such as USB, SPI, I2C, SDIO, etc. These interfaces and functions facilitate communication and data transmission with other devices, making the development project more flexible and scalable.

[0037] The sensor unit includes a smoke sensor 9 , a temperature and humidity sensor 10 , and a photosensor 11 .

[0038] The smoke sensor 9 is used to monitor the concentration of harmful gases (including liquefied gas, butane, propane, smoke, etc.). It is a tin dioxide semiconductor gas-sensitive material. The smoke sensor will automatically heat up after being connected to the circuit. At this time, tin dioxide absorbs oxygen in the air. When the measured gas exists in the air, the potential barrier at the grain boundary is adjusted by the smoke and changes, thereby causing the surface conductivity to change. The greater the smoke concentration, the lower the output resistance, and the greater the output analog signal. The change in smoke concentration can be converted into an electrical signal change through the digital-to-analog conversion module in the single-chip microcomputer.

[0039] The temperature and humidity sensor 10 is a temperature and humidity sensor with a calibrated digital signal output, which is used to monitor the temperature and humidity in the environment. Its humidity accuracy is ±5% RH, temperature accuracy is ±2°C, humidity range is 5-95% RH, and temperature range is -20-+60°C. The temperature and humidity sensor includes a resistive humidity sensing element and an NTC temperature measuring element, and is connected to the slave control unit 7.

[0040] The light sensor 11 is used to monitor the light intensity in the environment. It is equipped with a photoresistor. Its working principle is based on the photoelectric effect. The resistance value changes with the change of light intensity. When the brightness is high enough, the output of the digital output pin is "0", and when the brightness becomes dim, it outputs "1". It is connected to the slave control unit 7 to monitor the presence or absence of ambient light.

[0041] The alarm unit is electrically connected to the slave control unit 7 , and includes a first alarm light 14 , a second alarm light 15 , a slave fill light 13 and a passive buzzer 16 .

[0042] The first warning light 14 is an LED light, which is electrically connected to the temperature and humidity sensor 10 and is used to turn on when the temperature is higher than a preset temperature threshold to give an alarm.

[0043] The second warning light 15 is an LED light, which is electrically connected to the smoke sensor 9 and is used to turn on and give an alarm when the concentration of harmful gas is higher than a preset concentration threshold.

[0044] The slave fill light 13 is an LED light, which is electrically connected to the light sensor 11 and is used to be turned on when the ambient brightness is insufficient and is lower than a preset brightness threshold.

[0045] The passive buzzer 16 is electrically connected to the first alarm light 14 and the second alarm light 15, and is used to sound an alarm when both the first and second alarm lights are turned on, that is, when the temperature and harmful gas concentration detection results are abnormal.

[0046] The OneNET cloud platform 3 is a PaaS (Platform as a Service) IoT open platform created by China Mobile, which can help developers easily access and connect devices, quickly complete product development and deployment, and provide a complete IoT solution for smart hardware and smart home products. As long as the terminal device can be connected to the Internet, it can access the platform through any method such as http, edp, mqtt, etc. by giving a data packet. This platform has eight major functions: dedicated network and dedicated number, massive connection, online monitoring, data storage, message distribution, capability output, event alarm, and data analysis. It has a very powerful architecture and can help individual users and enterprise-level users manage their products more comfortably and conveniently.

[0047] The client 2 obtains data through the OneNET cloud platform after the network connection. The client 2 is a WeChat applet, written in JavaScript. The page design is divided into a home page and a voice control page. The home page contains various data displays such as temperature, humidity, and smoke concentration, which is convenient for users to monitor the data in real time. The voice control page combines the Baidu AI open platform and uses voice control technology to achieve the effect of being able to control the strength of the signal light on the device by voice. The WeChat applet of the client 2 is linked to the OneNET cloud platform, collecting the cloud platform data stream and displaying it on the WeChat applet home page.

[0048] The usage of the multifunctional environmental detection and alarm system based on the OneNET cloud platform is as follows:

[0049] The smoke sensor 9, the temperature and humidity sensor 10, and the photosensor 11 located in the multifunctional environment detection and alarm device 1 respectively collect and monitor environmental data, including temperature, humidity, concentration of harmful gases, and light intensity;

[0050] Upload environmental data to the OneNET cloud platform 3 in real time through the communication module, the OneNET cloud platform 3 displays various environmental data in real time, and the client 2 reads and displays the data from the cloud platform 3 in real time;

[0051] The host control unit 6 receives the data from the cloud platform 3 in real time and displays it on the OLED display screen 4, that is, the WeChat applet of the client 2 receives the cloud platform data in real time and displays it in the form of pictures and texts; at the same time, the WeChat applet can also be used to adjust the brightness of the host fill light 12 through the host control unit 6, and the voice recognition function of the applet can also be used to control the on and off of the fill light.

[0052] When the ambient temperature reaches the set threshold, the corresponding first alarm light 14 flashes to alarm, and when the smoke concentration reaches the set threshold, the second alarm light 15 flashes to alarm. When the first and second alarm lights are both turned on, it means that the temperature and harmful gas concentration detection results are abnormal, and the passive buzzer 16 emits a sharp alarm sound to warn on the spot.

[0053] Although the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the purpose of the present invention and the claims, all of which belong to the scope of protection of the present invention.
