Abstract: The paper has introduced the concept, characteristics, related research and engineering applications of digital substation. Combined with implementation of the electronic transformer, intelligent terminals, network communication and the IEC 61850, it has also clarified that the carrying out of the construction of digital substation at this stage is a feasible plan. And it pointed out that digital substation is an important development direction of the substation technology as a basic unit of the digital grid in the future.

Abstract: In recent years, with China's rapid development of social economy, the society requires more and more on the quality of College students. College Students' employment competition is the essence of the competition ability of employment. This article through the analysis of the ideological and political education on College Students' employment ability in manufacturing engineering, put forward to strengthen college students' Ideological and political education, improving the employment ability in manufacturing engineering of college students the specific methods and effective way.

Abstract: This paper introduces the limitation of traditional laparoscopic operation in the two-dimensional image,while an advantage of robot operation system is to use the most advanced 3D imaging system to make operation.It makes the operation target amplified 10 to times, which makes doctors see a depth-of-field, deep and stereoscopic image in the control platform, so as to make the operation more accurate and precise.The author, according to the driving types, classifies the development conditions of the representative cable endoscopy robot and wireless pill endoscope system, and discusses the research direction and prospect of the endoscopic treatment micro-robot.

Abstract: Todaro migration models a research model proposed by Michael P. Todaroin the early 1960s to 1970s, describing the society population mobility. The article starts with the current unemployment situation in China, with the perspective of Automation control and combined with Todaro migration model, analyzing and elaborating how to keep unemployment population under control in both technical and institutional ways.

Abstract: Hidden terminal problem in Ad Hoc networks is more serious because of asymmetrical links between different inter-node communications, in this paper, a power control based MAC layer channel allocation method is proposed, assigning different power values to different channels, select transmit power according to the distance between communication nodes, and then select the corresponding channel. Simulation results show that this method can effectively maximize aggregate throughput and throughput of unit energy consumption.

Abstract: Taking the mining subsidence as research object, a real-time monitoring scheme was designed. On this basis, a virtual instrument monitoring system based on LabVIEW was constructed. The data acquisition instrument collect real-time data through monitoring of subsidence and subsidence slope deformation by this system in range of mining influence, then control and transform it. After this, the data was transmitted to the computer terminal through wireless transmission equipment, and monitoring will be got after analysis and prediction by computer terminal. This result can provide mining of this area with real-time advice and guidance, to reduce the harms brought by mining subsidence and unnecessary economic losses.

Abstract: This paper proposes a on-line thickness measurement scheme of thin film based on the capacitance thickness sensor and introduces the composition and principle of thickness measurement system. Then it further states the principle and simulation of the RBF neural network, which can effectively predict the thickness deviation of thin film by setting the appropriate parameters. The monitoring method based on the RBF neural network will reduce production cost and make the film thickness uniformity better, combining the traditional film production line with an new idea of controlling the opening degree of wind ring.

Abstract: Monitoring and tracking dangerous goods can represent a great improvement in security and safety when transporting hazardous goods by water road. In this paper we propose a complete monitoring and tracking system, which is able to check at the same time the position and real-time status of dangerous goods of the ship, as well as the conditions in the cargo bay. The system exploits battery-powered environmental sensors (temperature, humidity, pressure, gas concentration and liquid level), connected by a ZigBee-based Wireless Sensor Network, This approach guarantees flexibility, ease of deployment and low power consumption. Collected data is then sent from the ship to a fixed server via a GPRS link. The GPS positioning system is integrated by the use of Navigation System, which also guarantees a precise estimate of the position when the GPS signal is weak or temporarily lost. When dangerous goods of the ship start leaking, the system can develop a plan to solve the accident, according to the situation at that time. The proposed solution has been deployed in a real environment, and some performance evaluation tests have been carried out.

Abstract: For solving the control problem of smart Building equipments in remote, introduce a design method of smart Building network which can realize the remote control of building electrical equipments by STC89C516RD+ and mobile telephone module of TC35I, give the Building networks mode, describe the software and hardware design of embedded gateway and its control method to the building electrical equipments in detail. The test result indicates that the capability of this system is stable and dependable, The result s was effect , it could meet the design challenge. and validates this scheme. The proposed program has the characteristics of high applicability and practical significance.
