This article put forward a method to realize the transmission between wireless sensor network and the Internet. The IOT (Internet of Things) gateway is used as part of the greenhouse monitoring system. The design compatible multiple access method such as LAN, Wifi, GPRS, EDGE, 3G and so on, also the data can stored locally. The IOT gateway uses STM32 as the MCU, μC/OS-III as the embedded operat...

A biosignal is used as a control signal for electrical stimulation to restore weakened muscle function due damage the central nervous system. In patients with system damage, sufficient contraction does not occur spontaneously. this case, applying can cause normal contraction. However, it necessary remove artifact caused by stimulation. This paper describes design that removes in real time using...

The article presents the concept of building a low-energy programmable controller architecture developed in accord-ance with IEC 61131-3 standard. universality concerns freedom choice central unit and possibility easy replacement control algorithm. One three methods software development distribution is selected for proposed solution. As part work, prototype was prepared based on evaluation elem...

Abstract Industrial boilers have strict requirements for water quality. It is necessary to adjust treatment measures and regular blowdown according the monitoring of phosphate soluble silica content in boiler avoid scaling, corrosion, deterioration steam quality, prevent major accidents. The traditional quality detection technology has a strong lag long time, which cannot meet real-time online ...

Abstract In the closed warehouse environment, this paper designed an intelligent temperature and humidity monitoring system based on modular design method to solve problem that product is easy damage. Based interaction between STM32 Main control chip upper computer, temperature, dual control, other functions can be realized. Experimental results show timely in warehouse. Moreover, has function ...
