Problems solved by technology

[0003] At present, in the field of mobile phone communication, the appearance of Smart Phone (PDA mobile phone) has just reflected this demand; Phones meet this demand to a certain extent, but they are all inseparable as a whole. The functions of PDAs are realized by the software of fixed phones, which destroys the portability of PDAs at the same time.
[0004] Therefore, for a huge number of fixed phone users, there is no effective communication device that can organically integrate the fixed phone and the portable PDA to realize the seamless link of the two while ensuring the portability of the PDA. sex

Embodiment Construction

[0022] In the interface relationship diagram between the PDA and the fixed telephone in Fig. 1, a total of 6 interface lines are used. There are two functions of the DC power supply VDD of the phone: one is to generate a plug-in interrupt for the PDA, and the other is to complete the power switch for the PDA. On the PDA side, the plugging status of the PDA is established through plugging and unplugging interrupts, so as to determine whether information related to the phone is displayed on the PDA; The seamless connection of the telephone; the working voltage of the PDA is different from that of the telephone. The three signal lines of interface 2 to interface 4 are level-converted on the interface of the telephone end, and an inverter composed of a first-level switch tube is used, and then the software When inverting during communication, a level conversion circuit composed of two-stage switch tubes can also be used; ESD anti-static protection measures should be considered for...

Abstract

The invented device realizes seamless interlink between Personal Digital Assistant (PDA) and phone set, making name card information in PDA and phone information in fixed phone set pass through by one point clicking. Moreover, PDA is separable from fixed phone set by inserting it in and pulling it out. Separated PDA and fixed phone set are two devices with independent functions. PDA is portable. When being inserted into seat of phone set, PDA can invoke all information included in phone set such as message registration, settings of telephone system and short message etc. When PDA is pulled out of seat of phone set, all information said above cannot be seen from PDA. In structure and function, PDA and phone set can be as an integrated body or as two independent bodies. The invention provides features of simple of operation, and practical use.

Description

Technical field [0001] The invention relates to a pluggable communication device for connecting a PDA (Personal Digital Assistant) to a telephone, which can realize the seamless connection and communication between the PDA and the telephone while ensuring the independence of the two, especially the PDA portability. This device belongs to the communication field. Background technique [0002] Although the functions of different grades of personal digital assistants PDA are very different, one of their most basic functions is to manage personal information such as business card books, itinerary plans, etc.; among them, the main function of the business card book is to record business card information at any time, so that it is convenient to make calls . The organic combination of PDA and communication terminal provides greater convenience for users. [0003] At present, in the field of mobile phone communication, the appearance of Smart Phone (PDA mobile phone) reflects thi...
