The hardware and software realization of a network video monitoring system was presented. A S3C2410 processor was used as the core of the embedded video server. The embedded video capturing software was developed according to V4L(video for linux) specification. The real time JPEG video stream was then transmitted from the server to the remote PC client through a socket connection. The system showed...
The paper describes the hardware and software implementation of combustible gas detection and alarm equiped STC12C5410AD microcontroller and catalytic combustion sensor. The select catalytic combustion sensor and design of high-precision differential amplifier circuit can meet the requirements of industrial and mining for combustible gas detection at room temperature. The measurement accuracy can...
The gas water heater is a controlled object with time delay and non-linear characteristics. So it is difficult to establish its accurate mathematical model. Because the conventional PID regulator has fixed parameters, the control effects are often poor. In this paper, the device uses a microcontroller AT-Megal16L and fuzzy control technology, The DIDO fuzzy controller is decomposed two DISO fuzzy...
As service robot, the cleaning robots for vertical type air-conditioning duct are studied in recent years. The detection system based on machine vision is a key component in the robot controller design. An effective method based on histogram similarity principle which is used in the machine vision is studied in the paper. Firstly, the configuration and workflow of the machine vision system is presented...
Abstract-A climbing mechanism for applying in vertical pipelines is presented in the paper. The mechanism can move in the pipeline by a suspending cable and can be positioned and fixed by a set of parallel linkage structure. A prototyping method is proposed for the mechanism system based on co-simulation of SolidWorks and MSC.ADAMS. A complex mathematical modeling process is avoided by this method,...
In order to get the photoacoustic(PA) image of micro-blood vessel deep inside tissue-mimicking phantom. A 532nm pulse laser with repetition rate of 10Hz was used as the pumping source. A wide band unfocused needle ultrasound transducer was used to collect time-domain PA signal of micro-blood vessels inside tissue-mimicking phantom by circular scan. The spatial resolution was measured by full width...
