Nowadays, Distributed Control Systems (DCS) are playing increasingly important roles in industrial process. Accordingly, the performance evaluation of DCS is attracting more and more attention. This paper focuses on the DCS real-time testing project in term of application. The test technique for the real-time performance of analog and digital signals, and the test technique for processing period of...
The paper introduces a design scheme to quickly build data acquisition system based on SoPC and LabVIEW technology. The slave computer of the acquisition system in the design adopts the EP3C10 chip of the CycloneIII series produced by Altera as the main control chip for digital control on A/D converter chip CS5550, digital signal after A/D conversion will be sent to the host computer through RS232...
A design scheme of remote model predictive control system is presented in this paper. Combined with the asynchronous messaging framework Errai, a network application system for remote model predictive control, which is based on GWT architecture, is developed and implemented by using RIA technique. The application field of MPC product is extended and the application function is expanded effectively...
Based on light intensity distribution, utilizing relationship between the diffraction angle and particle diameter, this paper introduces a direction operator in the particle inversion. Combination of the least squares method and genetic algorithm is proposed, which is a more effective method and reduces errors. The introduction of direction operator reduces the number of iterations, so the calculating...
Researched on the characteristic of the traffic flow, a new method of abnormal data detection on traffic flow based on the curve-fitting is presented. First, the historical data on traffic flow are divided into the traffic flow with high speed and the traffic flow with low speed by the clustering analysis. Then, the algorithm on the determination safety zone scope is obtained by the curve-fitting...
Intelligent Transportation Systems (ITS) aim at ameliorating the quality of urban traffic by controlling and guiding traffic flow based on the acquisition and evaluation of real-time traffic information. This paper puts forward a new method which makes use of Inter-Vehicle Communication to collect traffic information. Also, we have achieved dynamic route guidance at a typical branch road scene. Based...
The paper introduces the design of a novel insulin syringe based on MSP430 MCU. Controlled by an MSP430F4152 microprocessor, the syringe is designed to drive a stepper motor to complete each insulin injection with an exact preset dosage for diabetic patients. The product features small size, low power consumption, accuracy and easy manipulation, which is a best substitute for the traditional mechanical...
To resolve the problem of the manual analytical method adopted in water quality detection with bad real-time character, this paper introduces a novel kind of remote water quality measuring and monitoring system based on WSN. It has used wireless sensor network based on the ZigBee to realize the water quality parameter remote probing and the real-time monitoring function. Users can observe the current...
To prevent leachates from polluting the surrounding environment, geomembrane liners are often installed at municipal solid waste landfills. High voltage electrical technique can inspect 100% of the geomembrane material to detect and locate leaks. An improved electrical method is put forward in this paper. Some detecting electrodes are planted in the soil under the liner in advance. A voltage impressed...
A rule-based forward reference approach was proposed for the decision subsystem of the intelligent robot to avoid the complex decision logic and difficulties in improving the performance of the heuristic direct control solutions and to decrease the response time of machine-learning based intelligent approaches. The performance of this rule-based approach can be enhanced by modifying and improving...
A real-time electronic nose system is designed to analyze methane (CH4), hydrogen (H2) and their mixtures, the main combustible gases in the environment. The system is based on a single chip for acquiring measurement data from a gas sensor array. Four Fe2O3 gas sensors with little humidity effect are employed in the gas sensor array. A principal component regression (PCR) method is applied to process...
With the development of wireless Internet, SMS has become a hot spot. Short message service can be divided into two categories: one is information service, and the other is transaction service; which require a real-time system to deal with transactions. When receiving data, this real-time system responds within the stipulated time, and processes data as soon as possible, then sends results to the...
