Grid video surveillance system is an important part of smart grid.3D GIS-based grid video surveillance system combines 3D GIS technology and video monitoring technology,displays control points by 3D GIS spatial layout,and concentrates on the grid equipment monitoring.Operation steps and monitor equipment are decreased by using camera preset positions.With 3D GIS as the monitoring background,the bidirectional interaction among 3D vision,perspectives and camera preset location can be used for emergency management decision support and 3D simulation exercises by applying best path analysis method.The system is made up of station system,monitoring platform and client.Monitoring platform is composed of 3D GIS and video platform.3D GIS platform provides 3D GIS service to video platform by component invocation.Multiple data organization and spatial index optimization techniques are used in the system.Oracle database is selected to integrate and manage multi-source data.Multistage and piecemeal processing technology is applied to process three dimensional data.Signal softswitch technology based on SIP protocol is adopted to manage video data.Video monitoring for long span transmission tower is taken as the example for explaining the system construction and usage conditions.
Call testing is an effective method for telecommunication operators to monitor and evaluate their network. Comparedwith manual call testing, automatic call testing has more advantages. In the following sections, the automatic call testingsystem for CRC’s telephone network was introduced, including the key technology and strategy. Nowadays, the AutomaticCall Test System has been used widely in many CRC’s branches.
An afforestation project area in Dongying lies near to the Haihong Port and in-shore fisheries,which is the Economic Development Zone of Dongying.Because of complex soil and a high water table,serious soil salinization,the project of this kind is very difficult.So in order to improve the environment of this region,it has been proved that replacement of the land with living soil finds a way out for greening.For the protection of the new soil salinization,so a layer of living soil with something is set to fight against alkali.With engineering examples,this paper elaborates the afforestation and alkali discharging construction technology points in coastal saline areas.Engineering practice has proved that such a way is good in effect.
On strengthening and improving Teachers' Morality,we should look for the point of exerting all one's strength,the point of setting to one's strength and the point of destination of our strength.Changsha Social Work College has done some attempts to raise teaching ability as the point of exerting all our strength,to enhance teaching substantial results in class as the point of setting our strength and to promote students all-round development as the point of destioation of our strength.
The purpose and characteristics of higher vocational education determine that the students under such education are taken as a special group at a stage of vocational preparation. The vocational ideal education is thus the essential factor to guide vocational preparation and practice and is the key to educate the students to all-round development. It includes education of vocational cognition, vocational emotion education and vocational objective education and it should be taken through the whole process of higher vocational education.
On the basis of analyzing the meaning,function and effect of innovative culture and through comparing the effects of Chinese and west culture on technology innovation,this article points out that some ideas of our traditional cul- ture limit the innovation in our country,and uses an example empirically to analyze the reason that the positive circula- tion does not form in innovative networks among the supplier,the manufacturer and the user.Cooperation among each enterprise participant can improve the innovation competence and the whole innovation efficiency.Culture affects innova- tion,we should reform and innovate traditional culture firstly to make it had an innovative culture and surrounding if we want improve the level of technical innovation.
The article analyses the scientific meanings of the professional ethics educational way system, and points out its significance. It discusses construction principle of the professional ethics educational way system. Finally it explores each educational way's position and positive role in the professional ethics educational way system.
The connecting section between 1# and 2# tunnels of Dachun River 2nd Cascade Power Station is mostly built on major fracture and landslide mass of the Red River,for which the scheme of combining box culvert and aqueduct is adopted.Bent and pile foundation are applied to aqueduct foundation built at fracture zone and landslide zone,which is able to minimize the interference of construction engineering on landslide mass.In addition,the design of anti-slide pile for aqueduct foundation can effectively maintain the stability of aqueduct when landslide mass slips.Such design may be referred to by discharge structures built on landslide mass in free diversion line.
