For solving the problems of the technologies described above, a kind of IP off video intercom device that the utility model provides, comprise internet, video intercom terminal, it is characterized in that, described intercommunication terminal comprises: central processing unit, network interface, power supply and input-output equipment, described central processing unit connects described network interface, input-output equipment, and described power supply connects described central processing unit, input-output equipment; Each IP off video intercom terminal connects described internet by network interface.
Be that the central processing unit of described intercommunication terminal is a flush bonding processor to above-mentioned foundation structure optimized technical scheme.
The technical scheme that is more preferably is, the network interface of described video intercom terminal is the RJ45 interface, and described internet is the private IP network network or the public network of any compatible IEEE802.3 standard.
Further optimized technical scheme is, described power supply be external DC power supply or by netting twine with POE(Power over Ethernet Power over Ethernet) the mode circuit of powering.
Advantage of the present utility model is:
1. the IP off video intercom device that provides of the utility model, the prior art of comparing, the utility model has adopted the off framework, can more flexibly and dispose in industry spot fast.IP network can prolong communication distance in conjunction with existing optical fiber easily, and cost is also cheaper.Interconnect by IP network, every video intercom terminal status equalization, there is not principal and subordinate's difference, each video intercom terminal can both work alone, do not influence other-end, can install in any place that is linked into IP network flexibly and use, can realize long distance, lay flexibly in industry spot.Removed maintenance from, strengthened whole reliability simultaneously main frame.Solved prior art and be difficult to long distance, laid the problem of video intercom flexibly in industry spot.
2. adopt strong, the low in energy consumption flush bonding processor of performance, can dwindle the volume of video intercom terminal, can not only realize the video call function that traditional talk back equipment can't be realized, also can improve the reliability of equipment greatly.
The utility model provides a kind of IP off video intercom device, employing has the video intercom terminal that carries central processing unit, network interface, power supply and input-output equipment, saved the main frame in the IP intercommunication product in the prior art, make video intercom terminal dispersed placement neatly, IP network can prolong communication distance in conjunction with existing optical fiber easily, cost is also cheaper, and overall structure is simple, volume is little, working stability, and result of use is good.

Embodiment
In conjunction with Fig. 1 each building block of the present utility model and connected mode are introduced:
Structural representation of the present utility model as shown in Figure 1, the utility model difference with the prior art point is, the utility model has saved main process equipment, employing carries the video intercom terminal of central processing unit, network interface, power supply and input-output equipment, make terminal equipment simple in structure, be easy to dispersed placement, low cost of manufacture is applicable to small-sized communication network.
The effect of the IP network part among Fig. 1 is that each video intercom terminal is coupled together.The utility model can use the private IP network network or the public network of any compatible IEEE 802.3 standards when using the RJ45 interface as the external interface of data.
The structural representation of video intercom terminal in the utility model as shown in Figure 2, video intercom terminal of the present utility model mainly comprises: central processing unit, network interface, power supply and input-output equipment.Central processing unit is used for carrying out various programs to finish the function of video intercom terminal, and input-output equipment is used for operating to the user, simultaneously to user's display video.For central processing unit, preferably adopt flush bonding processor, for example adopt high performance Samsung S3C6410 ARM11 flush bonding processor.For input-output equipment, preferably adopt the camera of high pixel value, with image acquisition and send to flush bonding processor and handle; Adopt undersized high-resolution liquid crystal display, preferably adopt 7 inches LCDs, come to realize the function of video intercom and video monitoring to user's display video image and various operation interface; Input equipment also comprises button, and button partly is used for to user's operation, and the user presses different buttons can call out different intercommunication points.Can carry out individual calling and group calling operation.
For power supply,, also can be by netting twine with POE(Power over Ethernet Power over Ethernet by DC power supply) mode powers, and power supply unit branch gives processor, and internal units such as liquid crystal display screen provide satisfactory power supply.The voltage of all internal units is up to 3.3V, so power is very low.Network interface is used for receiving and send image, sound and the control data by Network Transmission.Flush bonding processor is the core of whole intercommunication, mainly is to handle image, sound and the control data that obtains from network interface.Other hardware components of video intercom terminal all link to each other with it and are subjected to its control.
For ease of at transmission over networks image and sound, video intercom compresses these data, and image uses the MPEG-4 form to compress, and G.711 sound use that form compresses.Because the operand of compression and decompress(ion) is very big, therefore, use Samsung S3C6410 ARM11 flush bonding processor in the present embodiment with hardware MPEG-4 code capacity, very fast for the encoding and decoding speed of image.In addition, flush bonding processor also be responsible for to receive the image of camera and to liquid crystal display displays images and handle various control commands.
The control flow chart of the central processing unit of video intercom terminal is as shown in Figure 3 in the utility model:
After the video intercom terminal powers on, hardware and protocol initializing can be arrived normal operating conditions.After network connect to start, the video intercom terminal can be according to the operation of process user and the control information that receives from network respectively of the interval in 1 second.If user key-press has carried out call operation, then can carry out user's operational processes and call out corresponding user; If receive control protocol, then corresponding operation (such as called) is carried out in the requirement according to agreement behind the protocol analysis.So constantly circulation is to carry out all functions.
The interconnecting relation of video intercom: after powering on, can each video intercom terminal, the target of each touch-call be set by the computer that inserts the intercommunication network.Can be arranged to 1 pair 1 calls out (individual calling) and calls out (group calling) more 1 pair.
It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
