Through some core modules that we have developed ourselves, function modules (such as power control, battery control, input-and-output points, environmental sensors, etc.) become landing application fields with different needs and are compatible with various communication interfaces (communication modules). They are highly compatible and scalable. Currently they are applied to landing environments, including industrial equipment, recycled power control, property management, and intelligent agriculture and fishery. 1. Products come up to industrial verification such as CE, FCC, EMC. 2. Design of AI-calculated low carbonization 3. Highly scalable and small-scale (down to 30% to 50% volume) 4. IO points compatible with AC and DC 5. Easy installation and quick accessibility Smart solution of buildings for apartment complex or office biuldings 1. With three systems that we have developed ourselves, solutions are able to provide with offices and factories as sites of public security, energy-saving, and dedicated outdoor air systems. 2. The maintenance and evaluation system of AI-activated elevators is able to predict maintenance time via AI modeling analysis. Besides, fault early warning can be done and security for elevators will be enhanced. 3. Master-slave smart and energy-saving LEDs can be deployed in the underground parking lots and factories. Instead of the lights turning off automatically without anyone inside, brightness will be lowered as someone comes and leaves in the deployment area. The purpose is to prevent anyone from dangers and accidents because of complete darkness in that area. 4. The energy-saving outdoor air system is able to help ventilate inside so as to have features of energy- and electricity saving, muteness and anti-noise, programmable control, etc. E-Heath solution for water treatment of dental clinics The solution is applied to dental disinfection equipment and can automatically adjust the concentration of disinfectant water for various disinfection methods such as surface disinfection and immersion disinfection. Fuctions: 1. Calculate the remaining amount of various chemical agents and the number of times various disinfection methods are used 2. Understand the equipment operation status and whether there are any abnormalities 3. Report usage and estimate the estimated time of completion 4. Reduce machine downtime due to various conditions
