M2M has been integrated into the national "Information Industry of science and technology develops 11th Five-Year Plan and 2020 long-term planning framework" as a key supported project. Network communication as the core of M2M technologies also restricts its development. SimCom Inc. produced SIM4100 is a TD-SCDMA/GSM mobile communication module solution. The article designs the minimal M2M...
This paper describes a real-time soil water content monitoring system from both perspectives of hardware and software. The system consists of an ATmega128 microcontroller with embedded μC/OS-II operating system, BD-I-type soil moisture sensors, RS-485 and RS-232 bus-based data transmission technologies. Compared to traditional microcontroller monitoring systems, the reliability and processing ability...
The main objective of this proposal is to automate control and communication systems of the train using High Performance Multi-core Embedded Processors (MCEP). This method will overcome the difficulties faced by the existing methods such as detecting cracks at rails, monitoring distance between rails, compartments monitoring, fire and smoke monitoring in compartments, and controlling of motors, transformers,...
While the Control Flow Checking (CFC) methods are using the ordinary instruction set and general Arithmetic and Logic Unit (ALU) features to protect the programs against the transient faults, this paper presents a new kind of CFC method, called feature specific CFC. The idea behind this method is using a specific internal hardware in modern processors which provides the ability to monitor internal...
Here introduces a monitor system technically based on ARM7 embedded micro processor (HMS30C7202) and Micro C/OS-II embedded operating system. The paper provides the scheme of the principal, introduces the connection method of outside signals, tells about how to transplant the Micro C/OS-II to the operating system, and shows the programming emphases and some source code of the majority of the program.
To promote the information technology development of the enterprise, achieve information integration and data share between different fieldbuses, by means of analyzing communication bus of industrial control system, the principle of the fieldbus protocol conversion is discussed. According to the basic construction of network, a scheme of fieldbus conversion is designed to accomplish the communication...
Based on the analysis of the basic principles and performance requirements of embedded monitoring system, combining with embedded technology, image compression technology and network technology, this paper designs and implements an ARM-based embedded network video monitoring system to achieve video image acquisition, compression and transmission. This system is a small, low cost, digital monitoring...
With the growing needs for advanced functionalities in modern embedded systems, it is now necessary to integrate multiple processors in the system, preferably on a single chip, to support the required computing complexity. The problem is that such multiprocessor system-on-chip (MPSoC) architecture is very complex and its internal behavior is very difficult to track. An effective tool for profiling...
In this paper, the video sever system is designed centered on IME6410. Based on the platform of embedded processor and Linux, after analyzing the internal relations among Video4Linux(V4L) specification, video driver and kernel of Linux, we propose a common method for driver development accord with V4L Specification.
Information and digital age presents tremendous opportunity to the development of embedded products and shows the embedded market a prosperous prospect, Web server embedded in equipment can provide uniform operation and control interface based on browser mode for any legal user accessing to its network, browser has become the front control board of equipment and a hot spot for development in recent...
The principal role of embedded software is the transformation of data and the interaction with the physical world stimulus. The main concern in developing embedded software for network application is the lack of published best practice software architecture for optimizing performance by means of reducing protocol processing overhead, memory usage, and power consumption. This paper presents the implementation,...
To provide visual communication over enterprise leased line, the remote video surveillance system should be a suitable architecture to take the place of analog video model. The paper gives a reference design of remote digital video monitor system based on embedded system and dual core processors which can apply to IP-based video system. It has the merits of low cost and high quality for digital video...
When accessing industrial Ethernet, embedded equipment can realize remote monitoring and control based on B/S mode, which is the developing trend of industrial control network. In this paper, the principles and methods of dynamic interaction between embedded equipment as server and client browser using CGI and Java applet are presented, which are used in the system of cement and slag compounding,...
