How to achieve innovative and smart IoT applications with Zigbee technology

Silicon Labs (also known as "Core Technology") recently assisted Yongmin Technology, an important design partner, and its customer, Manton, to successfully create an intelligent miniature circuit breaker (commonly known as an air switch) with low-power Zigbee wireless connection. ). This product not only provides power safety protection function, but also improves the accuracy of leakage current detection through digital monitoring and calculation. It then uses Silicon Labs' EM3585 / EM357 and EFR32 Mighty Gecko and other Zigbee wireless SoC series solutions to provide low-power wireless The transmission method is combined with the management APP of the client to push the alarm information in real time, which can improve the safety of the power system in an all-round way.

Innovative smart air drive turns into "safety steward"

Miniature circuit breakers, commonly known as air switches, are one of the most widely used terminal protection appliances in building electrical terminal power distribution devices. Traditional air circuit breakers have a certain power safety protection function, but because the line overcurrent detection is not digital, it cannot be accurately disconnected in real time; the leakage protection function can not be automatically limited by automatic detection and other technical limitations, so there are still casualties and electrical fire accidents. occur.

Manton's new intelligent air circuit breaker uses a microcomputer for data collection, comparison, calculation, analysis and recording. When a power failure occurs, it can quickly and accurately issue a power-off instruction, and the circuit can be cut off within 0.005 seconds at the fastest. National standards are nearly 20 times faster. The use of artificial intelligence technology to achieve accurate overcurrent, timely disconnection, automatic self-check for leakage protection functions, etc., thereby greatly improving the life safety protection when people get an electric shock, and the level of early warning and prevention of electrical fires.

The minimum leakage current that can be detected by Manton's smart circuit breaker is 1mA. Based on the management APP of the user's mobile phone, the user can do the leakage self-test at any time. In fact, a regular leakage self-check function is also set in Manton's plan. Once there is an abnormal line, an alarm message will be pushed to remind the user to check for hidden dangers. In addition, after this situation occurs, the empty meeting is automatically disconnected, and it must be closed manually. The remote control cannot close it, forcing the user to perform line inspection to protect the user's personal safety.

Silicon Labs / Yongmin ZigBee technology helps security upgrade

In terms of the core technologies and protocols of the new Manton series of products, Yongmin Technology is based on Silicon Labs' Zigbee software and hardware solutions, including EFR32 Mighty Gecko multi-protocol wireless SoCs and pre-certified Zigbee protocol stacks and software development tools to help its products Perform technology and security upgrades. Because Zigbee has the characteristics of close range, low complexity, low power consumption, low speed, low cost, short delay, large network capacity, and safety and reliability, Manton Smart Air Circuit and Smart Cloud Platform will transfer the current and voltage on the user side. , Leakage current, temperature, subdivision power, and fault alarms are integrated with building intelligence, smart energy, office energy saving, smart homes, smart campuses, smart hotels, smart communities, smart charging piles, and electrical fire safety supervision and other systems. Realize remote control, real-time alarm, statistical calculation, energy service, energy saving management and big data analysis.

In the future, the market for smart air-conditioning is huge, with the incremental market size at the level of 100 billion, and the stock market facing smart upgrades is even at the trillion level. Yongmin Technology will continue to cooperate with industry leaders such as Manton to deepen the service of intelligent fire protection and intelligent power technology based on Zigbee technology. While realizing the nation's green and safe use of electricity, we will revitalize China's related science and technology development and brand upgrades, and achieve more transcendence of national brands.

"Smart Power Management" Becomes the Focus of Industry

According to statistics, from 2011 to 2016, there were 524,000 electrical fires in China, which killed 3261 people and injured 2063 people. The direct economic loss was more than 9.2 billion yuan, which accounted for more than 30% of the total national fire and casualties. Among them, there were 17 major and severe electrical fires, accounting for 70% of the total.

Electrical fires have attracted great attention from the entire society and governments at all levels. In April 2017, the State Council's Work Safety Committee issued the “Notice on the Comprehensive Management of Electrical Fires”, and successively issued documents with the Fire Bureau of the Ministry of Public Security and the Office of the Ministry of Education to organize a three-year comprehensive electrical fire comprehensive nationwide Governance work, advancing smart fire protection and smart power construction.

At the same time, the National Energy Administration organized the preparation of the Intelligent Air Circuit Control (RC-MCB) Chinese energy industry standard to promote the user's smart power construction from the level of national energy policy and industry standards. Manton, one of Yongmin's technology partners, participated in the preparation of this new standard. As a Chinese brand, for the first time, Manton leads the international electrical giants, and has taken the lead in launching professional products based on innovative technologies for user-side power management.
