In order to improve the current use of the cutting machine, so that it can achieve unattended and continuous work. An automatic steel wire-changing cutting device consisting of PLC control system, hydraulic push rod mechanism, sensor monitoring system and wire-changing mechanism was designed. The working principle of the fault monitoring system in the blank cutting device, the flow and the way of...
The indicating and tracking accuracy of a radar is very dependent on the accuracy of the reflector, and is directly up to the rigidity and stability of its overall structure under various working conditions. As for the reliability of the overall structure of a high-speed mobile radar (hereinafter referred to as "the Radar"), the finite element model has been established with the method of...
The detector is mainly composed of CC430F5137, Lithium battery, Voltage monitor chip, temperature sensor, CO sensor and smoke detector, etc,. The detector is improved via the design optimization of hardware and software, which greatly reduces power consumption. Contemporarily, the detector uses BP algorithm program for judging whether there is a fire in the detect area. BP algorithm program is embedded...
A novel video smoke recognition method based on optical flow is presented. The result of optical flow is assumed to be an approximation of motion field. The method is proposed as following, first, moving pixels and regions in the video are determined by a background estimation method. Then, a pyramidal implementation of the Lucas Kanade feature tracker is proposed to calculate the optical flow of...
A novel video smoke detection method using both color and motion features is presented. The result of optical flow is assumed to be an approximation of motion field. Background estimation and color-based decision rule are used to determine candidate smoke regions. The Lucas Kanade optical flow algorithm is proposed to calculate the optical flow of candidate regions. And the motion features are calculated...
We propose an effective method to resolve blurred images with impulse noise. Our method has two steps. First, an improved adaptive median filter is proposed for image denoising; And second, the problem of deblurring the denoised image is formulated as to minimize the object function which consists of L1 data-fedility term and double regularization term. The minimization problem is solved by split...
Since the texture is an important feature of smoke, a novel method of texture analysis is proposed for real-time fire smoke detection. The texture analysis is based on gray level co-occurrence matrices (GLCM) and can distinguish smoke features from other none fire disturbances. For the realization of real-time fire detection, block processing technique is adopted and the computation of texture features...
