Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1, an embodiment of the utility model provides an intelligence indoor air quality monitoring and controlling means, include: the system comprises a battery module, a wireless communication module and a main control module;

Specifically, wireless communication module has constructed wireless communication's link between fresh air purification equipment and host system to realized installing fresh air controller in the room and the fresh air purification unit of distal end no longer need arrange signal control line and communication line, it is more convenient to install and use, and system installation cost is lower.

Wireless communication (Wireless communication) refers to long-distance transmission communication among a plurality of nodes without propagation through conductors or cables, and Wireless communication can be performed by radio, electromagnetic waves and the like.

Wireless communication includes a variety of stationary, mobile, and portable applications such as two-way radios, cell phones, personal digital assistants, and wireless networks. Other examples of wireless radio communication are GPS, garage door remote control, wireless mouse, etc. Most wireless communication technologies use radio, including Wi-fi, which is only a few meters away, and also include deep space networks, which communicate with the seaman number 1, and which are more than a few million kilometers away. However, some wireless communication technologies do not use radio, but use other electromagnetic wave wireless technologies, such as light, magnetic field, electric field, etc. The cost is cheaper, and the maintenance is simpler

Referring to fig. 2, in some embodiments of the present invention, the electronic ink display device further includes an electronic ink screen connected to the main control module, and the electronic ink screen is used for displaying data of the main control module.

The electronic ink screen is a screen using electronic ink. Electronic ink screens are also known as electronic paper display technology. Electronic ink is a new method and technology for revolutionizing the display of information. Like most conventional inks, electronic ink and the lines that change its color are printable on many surfaces, from curved plastic, polyester film, paper, to cloth. The difference with conventional paper is that electronic ink changes color when energized and can display changing images, such as a calculator or cell phone display. Another advantage of electronic ink screens over traditional computer display screens is that they are easy to read. The disadvantage is that the battery needs to be charged for use. The electronic ink screen looks like printed characters, so that eyes are relaxed, and energy and power are saved.

As a possible implementation manner of the above embodiment, referring to the room fresh air controller shown in fig. 3, three alkaline batteries are directly connected in series to serve as a power supply input, and RT9266 of RickTek is selected to provide up to 96% of conversion efficiency for voltage conversion. RT9266 is a Boost DC/DC converter with Boost architecture, small size, high efficiency, and low start voltage, and employs a self-adaptive current mode PWM control loop, which includes an error amplifier, a ripple signal generator, a comparator, a switching element, and a driver thereof, and can operate at high efficiency in a stable state over a wide load range without using an external compensation circuit. The starting voltage is lower than 1V, so that RT9266 can be used for 1-4 alkaline battery power supply applications, and the output current is higher than 300 mA. The working frequency is 450kHz, and a small external element can be used to work with the device. The combination of a quiescent current as low as 17 mua and high conversion efficiency allows full exploitation of cell performance. The output voltage can be set by two resistors. The power switch of 2A is contained in the power switch, and an external power element can be driven to work together with the power switch. And the safe start can still be carried out when the input voltage is lower than 1V, the static working current (off mode) is 17uA, and the driving current of 200mA can be output. The output voltage is adjusted by the voltage division of the 6 th pin (FB), and different voltages are output by different voltage division ratios, wherein the formula is as follows: vout (1+ R1/R2) × 1.25 × 2 — 3.3V.

The main control module adopts an RT1062 chip, the RT1062 is internally provided with a 1MB OCRAM, and a 512KB Flex RAM is shared with ITCM/DTCM. The proportion of OCRAM, ITCM and DTCM can be adjusted according to specific application. The frequency of the OCRAM is only 1/4 of the main frequency, while the frequency of the ITCM and the DTCM is the same as the main frequency, and different data need to be distributed to the corresponding RAM in order to obtain better performance. The core Cortex-M7 of the microcontroller is adopted based on the chip architecture of the application processor, so that the high-performance and rich functions of the application processor are achieved, and the characteristics of easiness in use, real time and low power consumption of the traditional microcontroller are achieved.
