Embodiment
The invention provides a kind of brand-new web camera design, the flexibility that is intended to increase substantially networking reduces networking cost simultaneously.Please refer to Fig. 3, Fig. 4 and Fig. 5, in a kind of preferred mode, described web camera comprises: camara module, ethernet switching module, wired network interface (can be the light mouth, also can be the electricity mouth) and AP module.Described camara module comprises camera processes (be called for short " IPC processor "), and camara module also comprises some professional hardware certainly, such as codec chip etc.These professional hardware are not showed in the drawings, can be realized with reference to various existing designs.The wireless traffic submodule (such as the WIFI module) that described AP module comprises the AP processor and links to each other with the AP processor.Described AP processor, it mainly is responsible for the data of AP module and the Business Processing of control aspect, is converted to 802.11 messages of wireless format such as 802.3 messages with wired form.Described wireless traffic submodule mainly is responsible for the message of wireless notch portion and is handled.Video camera of the present invention is below described in the processing of data plane and control aspect.These descriptions will embody design advantage of the present invention, and it is diverse with simple IPC and AP combination.
In traditional AP management, for the administration configuration of AP, can obtain the corresponding configuration page by the management ip address of visit AP.Such as the AP of family expenses, can visit a fixing management ip address, wait to be linked at the Web configuration page such as 192.168.1.1.The entire process process is that the processor of AP externally directly communicates.Yet in the present invention, management is not directly to be handled by the processor of AP module for the AP modules configured.In the present invention, be responsible for responding user's configuration management by the IPC processor.When at first the IPC processor receives user's logging request, can send the unified management page to the user, this administration page comprises camara module and the various config options of AP module.No matter the user wishes to dispose camara module still is the AP module, all can finish under this disposes the page.The tool implementation procedure is below described.
Be that mouthful to dispose the AP module by wireless traffic submodule wireless be example with the user, the user at first sets up wireless connections with the AP module, asks to login the administration page of the management ip address correspondence of camara module then by these wireless connections.The user logins and successfully obtains after the administration page, and the message interaction process between user and the web camera is as follows:
When step 101, AP processor are received the control message that the user sends, send to ethernet switching module by Port2.
The AP module completely sends from Port2 from the wireless mouthful of message of receiving for the wireless traffic submodule in the present invention, is decided the circulation direction of message by ethernet switching module.Because user visit is management ip address on the camara module, so the MAC Address of two layers of heads encapsulation of its message is the MAC Address of camara module, rather than the MAC Address of AP module.
Step 102, ethernet switching module sends to Port1 according to the MAC Address of this message with this message.
Step 103, the IPC processor is received this control message from Port1, obtains control command wherein, determines the operand of this control command correspondence, if operand is the AP module then changes step 104.As previously mentioned, when the configuration operation of user on the page is AP modules configured option, user's terminal can corresponding sending controling instruction to the IPC processor, the IPC processor according to this control command determine user's operand be camara module or the AP module.If towards camara module, isoparametric such as configuration codes speed, the IPC processor can be carried out this control command and revise corresponding parameters, and specific implementation can be handled with reference to existing mode.If handle especially towards the commentaries on classics step 104 of AP module.
Step 104, IPC processor are encapsulated into control command in the Ethernet message and send, and carry control mark in message, and wherein the target MAC (Media Access Control) address of this message is the MAC Address of AP module.
Because the configuration page is that camara module provides, what that is to say that the user visits is the IP address of camara module, and it does not have way directly and the AP processor is come into contacts with.Therefore it is initiated any configuration operation control instruction corresponding and will send to the IPC processor, the IPC processor then identifies to determine that according to the option of configuration operation this operation is at the operation of AP modules configured, corresponding control command is sent through ethernet switching module by Port1 arrive the AP processor then.Can be to adjust working channel such as this operation to carrying out this configuration operation after the AP processor is received, then the AP processor can corresponding control wireless traffic submodule change working channel.
Because the IPC processor also can send datagram, different with the control message is that what data message carried is the monitoring business data.The monitoring business data generally include multi-medium datas such as image or audio frequency, and the image that arrives such as camera acquisition passes through DSP or the back view data that generates of related hardware coding etc.For the control message, it is to need the AP processor that the control command in it is further handled; And for data message, the AP processor does not need to handle monitoring business data wherein, but need handle in message format conversion aspect, and send from wireless mouth by the wireless traffic submodule and this shows, for dissimilar messages, the processing of AP processor is also inequality.Among the present invention, the IPC processor carries the type that expectant control identifies to assist AP processor differentiation message at control message or data message.This control sign can be self-defining sign, can be the privatization utilization to the message reserved field.
Be example with a simple implementation, the IPC processor carries predetermined VLAN sign in the control message, such as VLAN100.The VLAN sign is publicly-owned field in the message, can keep a particular vlan and identify to realize, the VLAN sign of this reservation and different the getting final product of service VLAN sign.When receiving message, the AP processor checks the VLAN sign of this message earlier, if VLAN100 determines that then this message is the control message, otherwise determines that this message is data message.For the AP processor, be the control message if determine the message of receiving, then extract control command wherein, and carry out the configuration operation corresponding with this control command.If the AP processor determines that its message of receiving is data message, then the form with this message changes wireless message format into, and sends from wireless mouthful by the wireless traffic submodule.In fact, the control sign is not limited to the VLAN sign, and it can also be MAC Address or IP address, or is the combination of IP address and MAC Address, even can be developer's self-defining privatization sign in some message reserved fields.Need to prove, because the IP address of user's actual access is the management ip address of IPC module, here the IP address of AP module side only is used for distinguishing control message and data message, even if therefore the IP address of all video camera AP modules all is set to equally also can not cause conflict in network, unless the AP module of video camera is because some need to use this IP address and outsides to communicate very especially.
Step 101 has been described a very special control message transmittance process to step 104, in fact the control message that need handle of AP processor has arrived the AP processor at the beginning, but AP processor this moment " and not knowing " its need handle the entrained control command of this control message.In the present invention, this control message sends to the IPC processor earlier by the AP processor, the IPC processor find this control message operated to as if the AP module, detour from the IPC processor get back to the AP processor this moment, the AP processor just can be identified processing.Such processing mode seems that some detours, but at first its almost not influence for the video camera overall performance, because the quantity of control message is very little ratio with respect to data message.Secondly, because IPC developer will be the IPC exploitation configuration page usually, therefore come in to save suitable development task with the AP modules configured page is integrated, do not need to develop separately a new configuration page, and safeguard easily.At last and since the page of camara module integrated AP modules configured item, the AP module just no longer needs management ip address of additional configuration to provide the independent page to serve, such design has reduced configuration and management complexity, the user experiences and is improved.
In addition, can also realize camara module or AP modules configured by wired mouthful when the user is initial, this process is the same with the aforementioned processing principle, and only controlling message is to come in from wired mouthful, and it is the same arriving IPC processor processing procedure afterwards.In the control processing procedure, because the BSSID of AP module etc. provide the also not configuration of parameter of wireless service, so the AP module also can't normally provide the network insertion service when handling, and this moment, configuration operation need be realized from wired mouthful.In case after initial configuration is finished, just can insert from wireless mouthful and come in to realize configuration operation.
As previously mentioned, because Port3 is wired mouthful, so it has data message equally and sends on the AP processor by ethernet switching module, is identical to the processing of this AP processor, finishes format conversion equally by being sent by the wireless traffic submodule.And from the message that wireless mouthful (wireless mouthful) enters, no matter be data message and control message, the AP processor sends to ethernet switching module equally, is forwarded to Port1 or Port2 by ethernet switching module according to the MAC Address of message.
More than from the angle of single network video camera the processing procedure of various messages has been described.On basis of the present invention, those of ordinary skills can make a lot of reliable more and lower networking plans of cost.Below provide some networkings to realize illustrating that the present invention is in the outstanding representation of aspects such as cost and reliability.
Please refer to Fig. 5, two AP networking diagrams, video camera can serve as wireless relay, that is to say that video camera not only both can send the view data of self, also the view data of other video cameras can be transmitted towards the convergence switch direction, the deployment of AP quantity can be significantly reduced, even AP can be do not disposed.On topology, video camera A can arrive convergence switch by relaying video camera B or C.Can preferred network link in good condition under the video camera A normal condition, such as transmitting data by relaying video camera B, when the B catastrophic failure, it is obstructed that A detects link, meeting changes strategy and transmits data by the C relaying, and can not break down because of a certain via node influences the connection validity of back level node.For improving reliability, a plurality of alternative relaying video cameras can be set.
Please refer to Fig. 6, in the group-network construction of Fig. 6, because video camera has WIFI wave point and electricity mouth/light mouth wireline interface.Under the enough prerequisite of wireless bandwidth, whole networking does not need simple AP equipment, pull out a netting twine/optical fiber at last and be connected to and converge or Surveillance center, can also save the access switch of a low side, realize that the overall network video camera independently makes up access network.
Please refer to Fig. 7, if in user's existing wired network layout video camera, this moment, the user needed the expanding monitoring zone, need expand to the opposite side of its next door road such as the guarded region in certain building, so just can make up wired camera shown in Figure 7 and wireless camera mixed networking, in larger network design, many switches be can save like this, finally convergence switch or Surveillance center are connected to by afterbody AP or video camera of the present invention.
Please refer to Fig. 8, use video camera of the present invention can also make up loop network, operation loop network agreement such as RRPP, can improve the robustness of whole network, and such loop network does not need to dispose a large amount of switches or AP equally.And to dispose loop network in the prior art, and not only to dispose video camera, also to dispose a large amount of switches and AP, cost is quite high.
From above execution mode as can be seen; the present invention not only realizes with low cost; can also simplify the networking of monitor network greatly and reduce the monitor network networking cost significantly, and networking mode is versatile and flexible, can also protect the existing investment of user on network very effectively.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of making, is equal to replacement, improvement etc., all should be included within the scope of protection of the invention.
