Background technology

Existing caller identification device is the form that adopts a box, and an end connects telephone set, and an end adopts the USB connecting line to be connected with computer.During the phone incoming call; After receiving the bell signal first time; Begin to receive FSK (Frequency-shift keying) or DTMF (Dual Tone Multi Frequency) signal, behind decoding chip HT9032 and MT8870, after single-chip microcomputer formats processing; Parse telephone number, date, time, name of dialing party etc., through USB interface caller ID is sent to the application program on the computer again.In research and practice process to existing caller identification device, everybody finds that there is following shortcoming in existing technology the invention of the utility model:

(1) need install driver to use;

(2) take USB port, there is the not enough situation of USB port in the lower computer of some configurations;

(3) cost is high, and every computer need dispose a caller identification device;

(4) the incoming call box can cause computer can't receive incoming call if any fault;

(5) because every computer need dispose a called line indicator, inconvenient unified management and maintenance;

(6) can not insert multiple phone line simultaneously.

The utility model content

The utility model provides a kind of centralized caller ID display system, can address the above problem.

The utility model provides a kind of centralized caller ID display system; Comprise server and the centralized display device that is connected with server; Centralized display device comprises networking interface, CPU element and a plurality of line interface circuit, and line interface circuit comprises that the inlet wire interface goes out line interface, AC signal separator, high-ohmic cross-connection device, CID decoder and DTMF generator, wherein; Go out line interface and be connected to the AC signal separator; The inlet wire interface connects AC signal separator and high-ohmic cross-connection device respectively, and the AC signal separator connects the DTMF generator, and the high-ohmic cross-connection device connects the CID decoder; The CID decoder is communicated by letter with CPU element through local bus with the DTMF generator, and network interface communicates through data/address bus and server.

Preferably, said server is the PC server that the windows operation platform of incoming call receiver module, incoming call bullet panel module and dial module is housed.

Technique scheme can be found out; Because the utility model embodiment adopts a plurality of line interface circuits to carry out integrated design; And incoming information is transferred to server through network interface carries out centralized displaying, therefore cancelled USB port, avoided the installation of driver; And adopt server that incoming information or dialing are carried out control and management; And can on local area network (LAN) or wide area network, carry out resource-sharing, realize that a plurality of incoming calls insert simultaneously and are assigned on each operator's in local area network (LAN) or the wide area network the computer, make things convenient for unified management and maintenance.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the structure principle chart of centralized caller ID display system among the utility model embodiment.

Embodiment

To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiment that obtained under the creative work prerequisite, all belong to the scope of the utility model protection.

Embodiment:

The utility model embodiment provides a kind of centralized caller ID display system; Comprise server and the centralized display device that is connected with server; Centralized display device comprises networking interface, CPU element and a plurality of line interface circuit, and line interface circuit comprises that the inlet wire interface goes out line interface, AC signal separator, high-ohmic cross-connection device, CID decoder and DTMF generator, wherein; Go out line interface and be connected to the AC signal separator; The inlet wire interface connects AC signal separator and high-ohmic cross-connection device respectively, and the AC signal separator connects the DTMF generator, and the high-ohmic cross-connection device connects the CID decoder; The CID decoder is communicated by letter with CPU element through local bus with the DTMF generator, and network interface communicates through data/address bus and server.

As shown in Figure 1 particularly, the server among the utility model embodiment adopts the PC server of the windows operation platform that incoming call receiver module, incoming call bullet panel module and dial module are housed.The software that dial module can combine to move on the PC server dials.The incoming call bullet panel module of installing on the PC server is responsible for notifying user's caller ID, and is ejected this caller ID on computers when receiving incoming call.The incoming call receiver module moves on the PC server, handles the incoming telephone signal that sends over from centralized display device, caller ID is forwarded to the user of appointment through local area network (LAN).It is understandable that incoming call receiver module, incoming call play panel module and dial module is accomplished task separately by the program command control of the operation on the PC server.

In centralized display device, comprise a CPU element, CPU element is responsible for a plurality of incoming calls and the concurrent processing when calling, and is responsible for the service logic of whole calling and the control of call flow simultaneously.CPU element has local bus interface and is used to receive the data on the local bus; CPU element also links to each other with network interface simultaneously; Said network interface can be RJ-45 interface or RJ-11, or even USB interface, and server carries out data or signal transmission through bus and network interface; Network interface is when having incoming call; Be responsible for caller ID is forwarded on the PC server, handle by the incoming call receiver module on the PC server, when Outgoing Call; Network interface is responsible for the telephone number of being dialed is forwarded to CPU element, realizes the outer calling function of phone.
