This article presents the design ideas of patrol system based on real-time image acquisition in patrol points. In this system, the image acquisition terminals are mounted on many patrol points, which are set in a predetermined patrol line. When patrol officers arrived at a patrol point, the image acquisition terminal mounted on the patrol point will capture a live image via a GPRS MMS module ,and then the image acquisition terminal sends this image to the central control unit in a form of MMS. The central control unit receives the sent MMS message, and separate out the image information from the received message, and then saves it to a database. According to the actual test results of this patrol system, it can not only meet the design requirements, but also the whole system has a high stability and reliability.

Image Information

Research and develop an intelligent tracing robot system based on HCS12 SCM. The system uses Freescale HCS12 series 16-bit SCM MC9SXS128 as its central control unit and apply a CCD camera to obtain road image information. After analyzing and calculating obtained road image, the system controls servo steering and adopts PID control strategy to control the speed of DC motor. The result proves this method can make intelligent tracing robot system move forward quickly and smoothly following the black line.

This article aims to show the possible savings in electricity costs in smart building installations with the use of new version of Raspberry Pi 3 model B + as the control unit in intelligent building automation systems. It presents a comparison of the consumption of electricity in two units used in the central control systems, i.e. a small Windows-based computer and a Raspberry microcomputer. The power consumption of these units was measured during the rest period and during standard operations in the intelligent installation system. The conducted measurements proved that the use of the new updated version of Raspberry Pi 3 model B + as the central control unit in intelligent building management systems is more economical and energy-saving.

Sprayed Coating

A new automatic high velocity arc spraying system was developed. The system was consisted of five units, i.e. central control unit, operating machine, positioner, touching screen and high velocity arc spraying equipment. The central control unit is controlled by a program, controlling other four units. Spraying parameters could be input and modified on the touching screen during spraying. The moving of spraying gun was carried out by motion arm of the operating machine. The rotational velocity and angle of components to be sprayed was controlled by positioner. The spraying process for a cylinder body of automobile engine with the system was introduced in detail. The auto and manual arc spraying have been used to fabricate coating. The microstructure of the coatings prepared by the two spraying processing was analyzed. The result shows that the auto sprayed coating has a more uniform and compact structure than that of the manual sprayed coating.

There are three main algorithms for autotuning a transmission electron microscope (TEM), (1) image variance method, (2) tilt-induced image shift (TIS) method, and (3) automated diffractogram analysis method (ADA). In practice, each method has its own advantages and limitations. Therefore it is necessary to obtain a comprehensive understanding of each in order to be able to select the most appropriate one(s).There are four key elements in any TEM autotuning setup, (1) microscope control by an external computer, for example via the standard RS232 serial port; (2) proper image acquisition device, for example a TV or a slow-scan CCD camera; (3) appropriate software for image analysis, processing, and optimization; (4) a fast computer that is the central control unit in the setup and dictates all the activities and operations.
