Shenyang was a representative heavily polluted industrial city in northeast China. Two types of urban area with significant spatial position difference were divided by arterial traffic as the surrounding and the core urban area. To reduce the impact of disturbing factors such as firecrackers in the traditional Chinese festivals, the observation period of the monitoring data was selected from November...
Sudden Oak Death (SOD) has emerged rapidly and repeatedly in US and Europe, with devastating impact upon forest ecosystems and causing severe economic hardship to nursery operation. It has potential host vegetation with large spans in China which has similar environment and climate. Yunnan province was selected as typical study area here for EU and NA evolutionary lineage. It is assumed that there...
This paper shall introduce the Taipei City Mass Rapid Transit underground section stations chiller Supervisory Control And Data Acquisition (SCADA) system and customized application software system development. Each station's existing chiller machine microprocessor Human Machine Interface (HMI) utilizes a standard communication protocol convertor and the environmental control system control room Open...
Solar PV (Photovoltaic, PV) power generation is currently one of the renewable energy with environmental-fashion trends and new alternative-green energy. Taiwan is located in a subtropical zone with sufficient sunshine and abundant solar resource, and thus, has great potential in solar power development. This project sets up a 30.78kWp grid-connected PV array demonstration system on the roof of a...
This paper presents the applications of a human machine interface (HMI) system in thermal power plants. its will study remote testing and operation of diesel fuel generators through the principles of normal practice. The control authorizations of a Thermal power plant Mechatronics equipment control system can be divided into three levels. The first level, the local override control. The second level...
Unstable slopes have been monitored since the beginning of the last century. Current electro-optic detection technology can achieve automatic monitoring remotely with high safety and includes such methods as time domain reflectometry, optical time domain reflectometry and Brillouin optical time domain reflectometry. However, these technologies cannot simultaneously meet the requirements of distributed...
When someone is standing in front of a presentation screen, the contrast between the projector light and the indoor illumination is, as a rule, too great. This causes frequent contraction of the pupils of a person's eyes and thereby great discomfort. In this paper we use both an embedded system and a Webcam to design a digital projector which by using image processing methods reduces dazzle in the...
Distributed systems are widely used in the field of measurement, control and monitoring alarm. The reliability of bus topology and overall costs are the key to distributed bus applications. This article analyzes the shortcomings of mainstream distributed alarm system, and proposes one-wire bus type token network topology. Then, one-wire bus driver circuit which supports wired-and function is designed,...
The atmospheric electric field is an important parameter during the whole thunder process, so the electric field monitoring is an effective method for local lightning forecast in key lightning protection region. The electric field monitoring data can validate the accuracy of weather forecast in a local region for meteorological department, or validate the dependability of lightning protection measures...
