Release date: 2017-05-03 Asthma has become one of the most common diseases in the world today, especially in children, where asthma spreads more widely. According to the Global Asthma Prevention and Initiative Committee (GINA), approximately 300 million people worldwide suffer from asthma; according to WHO predictions, asthma patients will increase to 400 million by 2025. The number of asthma patients in China has increased from less than 20 million to 30 million a decade ago, and the number of patients has continued to increase. The first Tuesday of May each year, which is today, is designated as "World Asthma Day." This is a commemorative event launched by the World Health Organization to increase awareness of the current state of asthma and enhance the prevention and treatment of the disease by patients and the public. Asthma butler has also chosen to publish the "White Paper on the Status of Chinese Asthma Management" through the data collected by tens of thousands of intelligent drug monitoring devices and intelligent respiratory warning devices based on data from 278,306 asthma patients. If you want to know the true state of asthma treatment in China? Which cities have better asthma control? The most popular use of asthma users? Common misunderstandings in asthma treatment? How to achieve better asthma control with the most advanced asthma management methods? Just follow us to read this white paper. Source: Arterial Network

1. Solar panel: The solar panel is an important part of the mobile phone software of the solar power generation system, and also a part of the practical value of the mobile phone software of the solar power generation system. Its function is to convert the professional ability of radioactive substances in natural light into electric energy, or send them to storage batteries, or promote load work.
2. Solar controller: The solar controller is used to control the operation of mobile phone software in all systems, and has the functions of overcharge protection and overcharge maintenance for the battery. In areas with large temperature difference, the qualified controller shall also have the function of temperature compensation. In the mobile phone software of the solar road lamp system, there must be light control switch and time control solar road lamp operation.
3. Battery: generally valve controlled maintenance free lead-acid battery. In the mobile phone software of small and medium-sized systems, in cold weather areas, a solar gel battery needs to be configured, which can be used at low temperatures, with high efficiency and is not vulnerable to major damage. Its function is to store the electric energy of the solar panel when the sun shines, and then release it under certain conditions.
4. Variable frequency power supply: split wave type and sine wave type. In order to provide power for 220VAC electrical products, it is necessary to convert the DC stabilized voltage power supply in the solar power generation system software into AC circuit energy, so DC AC variable frequency power supply is required.
