The System Of The Wireless Digital Spread For Message & Information

The development of technology in all kinds of fields, especially in the communication field, impulses the development of the Information Industry. As for everyone today, information is the basic right of our life and people think it is essential and rightful. When all of us enjoy the wonderful world, we almost ignore some old but still standing message tool, it is the Beep-Pager System.From middle of 20 century, Multitone company creates the first technical Beep-pager system for the hospital calling for the doctor. At that time, that system is very simple and has little application. Now the wireless Beer-pager system develop more and more perfectly and its application reach its top. The whole world have been covered in the Beer-pager System Net. With the development of the Digital Technology, the digital communication rapidly spreads up and the Signalling system undergoes the process from the analog to digital era. Such as the POCSAG, it is the classical represent, and it extends to all over the world and becomes the criterion in the system of all the Beer-pager System. Now, the basic device of the Beer-Pager System has been developed perfectly and it becomes the rich technical resource.However, the mobile communication is more popular and more life-force today, more and more markets of Beer-Pager for the personal communication have being replaced by the mobile communication. The Beer-Pager system has been enfaced the developing perspective problem. Of course, in the circumstance of a great rich technology resource, every resource can be used. Just in this chance, my dissertation is conceived. In order to solve above problems and further impulse the information industry, my dissertation aims to transplant the Beep-pager system into a message display, this system is the synthesis application of three high-new technologies: Microelectronic, Communication, Computer.My dissertation's object is the electronic display which lie in the golden place to issue some information and advertisements. It's function and theory is using the Beep-pager system as the communication channel, and adding an intellectual hardware and personal-computer software. Finally the information and advertisements can be displayed in the electronic displayer in control. In thedissertation, project has the following feature: message wireless control in the urban field; multiple consumer server; abundant display and time control. In the course of research, a few of technologies is fulfilled including: the communication between the PC and MODEM; database manager; message decode, compact and package; serial communication; hardware & software for baseband message accessing; decoding of calling Signalling;Through practical debug and tryout, now the dissertation has been completed, and the product based on this dissertation runs very well.
