With registering one’s residence of broadband Internet, a lot of scenes that can only be imagined in the past will be all realized. A lot of producers are devoted to developing various home information products, the pouring in constantly of in addition the foreign products after entering the WTO in China, can be expected in the future to be from three to five, these intellectual home furnishing will employ gradual entering into the family, installing the intellectual home furnishing wiring system of broadband offers for the application and realizes the platform, otherwise present the situation that the new products can’t be used. ...

The distributing frame manages the most important assembly in the subsystem, the pivot that two subsystems connect alternately that realize vertical main line and level to connect up. The distributing frame is usually installed on the cabinet or wall. Through installing the attachment, the distributing frame can meet the needs of UTP, STP, coaxial cable, optic fibre, audio frequency and video completely. The commonly used distributing frame has paired line distributing frame and optic fibre distributing frame in the network project. ... Read more

Monitoring system require the difference according to different user, the intersection of system and scale, coverage, the intersection of signal transmission and the intersection of distance, information capacity,etc. and function and quality index in the system often, and adopt different transmission means. Often demand to transmit the alarm signal, audio frequency signal, control the data signal,etc. in the monitoring system too, but it was good and bad that the picture transmitted monitoring system of the decision, it is beneath most mention. Because the amount of information of the dynamic picture signal is large, the bandwidth frequently, it is strong to monitor the real-time character, so the focal point transmitted is the transmission of the picture signal of the video. ...

With the progress of science and technology, the function of the embedded system is developed complicatedly briefly gradually, develop the difficulty and thereupon improve too. The use of the embedded operating system, shield some hardware information, offer the unified platform to developers, have reduced and developed the difficulty, has improved the repeated utilization ratio of the code. medical treatment, car, Aero-Space in some special fields ,Expect very much to the real-time character of the embedded system. In these occasions, the task must be responded to within designated time and finished correctly. And real-time operating system RTOS Real Time Operation System One’s own operation, will inevitablely cause the decline of performance, when the task quantity increase, this kind of decline is more obvious. For example, use? Spurt C/OS-II real-time operating system and run on PowerPC processor, in TimeTick clock beat Is cycle 10? Spurt s, run under the situations of 64 tasks, TimeTick has cut off CPU time that the function took up and has already been up to 42% [1 ]. ... Read more

It is a great challenge that the engineer faces that PCB connects up that the board of telephone circuit of honeycomb connects up, the modern cell phone nearly includes all portable subsystems, each subsystem has a each other contradictory demand. A design perfect PCB must be while giving full play to each interconnected equipment performance advantage, avoid the mutual interference between the subsystems, so, have to trade off and consider to each sub systematic function as to the conflicting requirement. Though the audio frequency function of the cell phone is increasing continuously, pay concerns that the voicefrequency circuit PCB connects up few. ... Read more

Summary: Have introduced ZigBee technological agreement and performance and characteristic of CC2420 and MMA7260 briefly, design a kind of data collecting system of wireless sensor based on CC2420 and MMA7260, provide concrete design method of software and hardware and real test result. This system selects to gather vibration acceleration signals of the organization with three high sensitive axle acceleration sensor chips MMA7260, and then transmit CC2420 of the agreement to send the data to receiving the device through supporting ZigBee wirelessly. ...

The comprehensive wiring system is still commonly more used, then I have studied the demand analysis of the comprehensive wiring system, and problem and solution met in the actual project, take out and share with everybody here, it is useful to everybody to hope. ... Read more

With the development of IP communication, the communication way of IP pronunciation emerges in an endless stream, operation cost of the bank, input and output,etc. become the focus paid close attention by every large bank, regard reducing the operation cost as the magic weapon that bank improves per person’s benefit, the interests maximize all without exception. Realizing in the unified IP network the pronunciation, video, data have already become the irreversible trend rationally and effectively, IP set communication is through the integration of the pronunciation, video and data, in order to build up a communication platform based on IP, for realize abundant the intersection of end and IP communication service to reach end lay the foundation in the future. While inheriting traditional pronunciation, video business and investment, can be convenient to support the new business, make the financial branch’s communication system become and improve the driving force of the competitiveness. ...
