According to functional integrity, IEEE802.15.4 has defined two kinds of equipment: full-function device (FullFunctionDevice, FFD) and simplify function device (Reduced Function Device, RFD).Full-function device can with simplify function device or other full-function device is communicated by letter, can only communicate by letter with full-function device and simplify function device.The ZigBee standard has defined three kinds of network equipments on this basis: individual territory net telegon (PAN Coordinator), router (Router) and terminal device (End Device).The PAN telegon is the starting point that network is set up, and is responsible for the initialization of ZigBee network, determines the physical channel of a territory net identifier (PAN Identifier) and network work, and plans as a whole the distribution of short address.The ZigBee telegon must be a full-function device, and a ZigBee network has only a PAN telegon.The ZigBee router is a full-function device, adds in the network of PAN Coordinator establishment, and it can obtain certain space, 16 short address, in its communication range, it can allow other node to add or deviated from network, distributes and the withdrawal short address route and forwarding data.The ZigBee terminal device promptly can be that full-function device also can be to simplify function device, it can only with his father's node communication, obtain relevant informations such as network identifier, short address from its father node.
Define the gate inhibition in the radio visual entrance guard system of the present invention's design and controlled main equipment, subscriber terminal equipment, three kinds of network equipments of wireless routing device.Wherein, the gate inhibition controls main equipment and finishes an all functions of territory net telegon, is FFD equipment; Subscriber terminal equipment can have the function of router, and it must be a FFD equipment; Routing device is just finished the function of transmitting Frame, also must be FFD equipment.
Clearly defined three kinds of topological structures in the IEEE 802.15.4/ZigBee agreement: hub-and-spoke configuration (Star), bunch shape structure (Cluster tree) and reticulate texture (Mesh), as shown in Figure 3.
Star Network is made up of a PAN telegon and one or more terminal node, with the PAN telegon is the center, it is responsible for initiating to develop and manage whole network, and other node (terminal node) is distributed in the coverage of PAN telegon, and direct and PAN telegon communicates.In the forming process of Star Network, the first step is set up the PAN telegon exactly.Any one FFD equipment all has the possibility that becomes the PAN telegon.How a network determines that the network coordinator of oneself is determined by upper-layer protocol, and the strategy in the software design of the present invention is: a FFD equipment is after being activated for the first time, the at first request of broadcast query PAN telegon, if receive to respond in the explanation network and had network coordinator, by a series of verification process, equipment just becomes the conventional equipment in this network again.If do not receive response, perhaps verification process is unsuccessful, and this FFD equipment just can be set up the network of oneself, and becomes the PAN telegon of this network.The PAN telegon will be an only identifier of network selecting (PANID), and the equipment in all these Star Networks all is owner's relation of stipulating oneself with this identifier.After selecting an identifier, the PAN telegon just allows other equipment to add the network of oneself, and is these device forwards packets.Two equipment in the Star Network are mutual communication if desired, and elder generation sends to the PAN telegon to packet separately, is transmitted to the other side by the PAN telegon then.
In bunch tree network, most equipment are FFD equipment, and RFD equipment always is connected in the network as the leaf equipment of bunch tree.In this network, equally also have only a FFD equipment can serve as individual territory net (PAN) telegon of whole network.The PAN telegon may be the same with other equipment in the network, also may have than more computational resource of other equipment and energy resource.The PAN telegon at first oneself is made as a bunch head (cluster header, CLH), and with bunch identifier (cluster identifier CID) is set to 0, selects a PAN network identifier that is not used for this bunch simultaneously, forms first bunch in the network.Then, the network coordinator beacon frame of going on the air.After nearby device is received beacon frame, just can apply for adding this bunch.Equipment could become a bunch member, is determined by the PAN telegon.If request is allowed to, then this equipment will as bunch subset add the neighbor list of network coordinator.Initiate equipment can join the parent device of bunch head as it in the neighbor list of oneself.All equipment that add in the network can carry out message exchange with its parent device.Discussed above just one by single bunch of the simplest bunch of tree that constitutes.The PAN network coordinator can specify another equipment to become new bunch of head of adjacency, forms more bunch with this.New bunch of head can select other equipment to become a bunch head equally, further enlarges the coverage of network.Message was transmitted between but too much bunch head can increase bunch delay and communication overhead.Postpone and communication overhead in order to reduce, bunch head can select farthest communication facilities as bunch head of adjacent cluster, can dwindle the jumping figure that message is transmitted between different bunches so to greatest extent, reaches to reduce to postpone and the purpose of expense.
The network of MESH mesh network topologies structure has strong functions, and each node links to each other with other two nodes at least, can communicate by letter by the mode of " multistage jumping ", and this topological structure can also be formed very complicated network.The MESH fully connected topology has higher reliability, also possesses self-organization, self-healing function, but all more complicated are realized and safeguarded to its complex structure.
In the wireless sensor network practical application, often select the suitable network topological structure neatly according to application need.The application of combining wireless visual door control system, a bunch tree network topology structure is fit to this application background.It is the network of controlled target with sub-district or unit building that the PAN telegon is set up one, in this PAN telegon range of control, by its initialization network-related parameters and maintaining network, other subscriber terminal equipment or wireless routing device add wireless interconnected network of formation in this network to.If with a sub-district is controlled target, then a unit building can be used as a branch and organizes user node in this building.If with a building is controlled target, then can organize user node in this floor as a branch by first floor.
Transmit data to terminal device with from different and different with network topology structure of the affirmation mechanism of terminal device transmission data.The data-transmission mode of ZigBee technology is divided into three kinds of data transmission transaction types: first kind is that terminal device sends data to telegon; Second kind is that telegon sends data, and terminal device receives data; The third is to transmit data between two terminal devices.For example in the hub-and-spoke network topology structure, when terminal device wanted to send Frame to telegon, it only need send to telegon with Frame when detecting idle channel conditions.If telegon will send to terminal device with data, it can decide data mode according to the state of terminal device receiver: when the terminal device receiver was in accepting state all the time, telegon adopted CSMA-CA mechanism to send Frame when channel idle; And when the terminal device receiver was in closed condition, it can be kept at Frame in its transmission buffer, till target terminal equipment comes data query clearly.
In bunch tree network, it is that its receiver is opened in opening or agreement in a period of time that each routing node must keep its receiver always.After selecting by the routing algorithm introduced previously and having set up data transmission link, the data transmission mechanism between each is jumped just with Star Network in similar.When data transmission, in case set up data transmission link, follow-up data frame transfer just can directly adopt CSMA-CA mechanism point-to-point along setting transmission up to the transmission of finishing all Frames.
The present invention has designed innovatively based on the image/audio data frame of link establishment mechanism and has striden a layer transmission mode when design ZigBee wireless image transmission application protocol stack.This mode just is used for the continuous transmission of image/audio data frame, and other all Frames all carry out according to the ZigBee standard agreement, promptly adopt the data transmission mechanism of introducing previously.
In the embodiment of the present invention, at first set forth the General layout Plan of radio visual entrance guard system, introduced the hardware scheme of working method, principal feature and each function device of the function of each equipment, system in the system.Secondly, introduced the ZigBee technology that system design is adopted, and respectively from aspects such as protocol architecture, network topology structure, Routing Protocol and data transmission technologies to this technology the application the radio visual entrance guard system study, draw corresponding implementation.
Aspect the hardware realization, the designed wireless image transmission plan of the present invention is primarily aimed at current intelligent residential district wireless entrance guard and is applied as background, for the sub-district provides radio visual entrance guard solution into gate control.The function of this system is that transmission medium is realized with the wireless network of network coordinator (Coordiantor) tissue.This gate control system is made up of following function device: the gate inhibition controls main equipment, subscriber terminal equipment, wireless routing device, front end recognition equipment, electric lock actuating equipment and entrance guard management workstation.Wherein the gate inhibition to control the major function of main equipment be that telegon (Coordinator) as wireless network comes the organizational protection network, and provide the interoperability communication interface for front end recognition equipment, electric lock actuating equipment and entrance guard management workstation.Consider the design proposal of the existing comparative maturity of front end recognition equipment, door lock actuating equipment and entrance guard management workstation, in follow-up hardware plan design, only provided them and controlled design for Universal Interface on the main equipment the gate inhibition.
Gate inhibition in this radio visual entrance guard system controls main equipment, subscriber terminal equipment and wireless routing device hardware configuration separately and has corresponding difference.In order to reduce design cost, use among the present invention to comprise that the wireless network node of above-mentioned three kinds of equipment all functions carries out the hardware design introduction.
Wireless network node is made up of following parts as the hardware elementary cell: main control module, radio receiving transmitting module, camera module, by key control and indicating module, display module, peripheral interface and power module.In this system's practical application, the gate inhibition controls main equipment and comprises all parts except that display module; Wireless routing node need not camera module and display interface; The user terminal node does not comprise camera module.
Adopted the design proposal of main control MCU chip+radio receiving transmitting module in the wireless network node hardware plan.The type selecting and the characteristics thereof of these two kinds of main chip will be discussed below.
According to ZigBee technology application characteristic, when selecting main control chip for use, mainly consider following aspect: the interface of itself and radio receiving transmitting module; On the basis of simplifying its hardware design, must have the operation enough ROM program spaces of ZigBee protocol stack and move required RAM for it; The characteristics that cooperate the low-power consumption of ZigBee technology to use; Have debugging interface and abundant gate control system peripheral interface resource easily.In view of above consideration, the C8051F121 single-chip microcomputer meets above-mentioned requirements, has the power management of two kinds of (idle and shutdown) software programmables simultaneously, is the embedded system solution with low-power consumption application characteristic.
The ZigBee chip is the most ripe ring of development on the industrial chain, since 2004 formally proposition standards of ZigBee alliance in the end of the year, the ZigBee chip factory begins to release the chip that meets the ZigBee standard, as the CC2420 of TI, and the MC13192 of Freescale, the SN260 of ST.Because factors such as volume, power consumption and cost are the key factors that the ZigBee technology is used in the wireless network success or not, therefore, the ZigBee chip business begins to integrate microcontroller and RF transmission chip, develops integrated single-chip, as CC2430, EM250, JN5139, MC13214 etc.
When systematic lectotype and hardware design, the present invention has adopted the scheme of main control MCU chip+radio receiving transmitting module, and does not adopt the single-chip solution.Though single-chip solution area occupied is little, can reduce power consumption, buy it and develop software and debugger, increased cost.Simultaneously, its microcontroller peripheral resource-constrained in the single-chip solution, if the expanding peripherals resource just will certainly increase the cost of system, the area and the power consumption of circuit board, the principle of dirigibility in the discontented pedal system design, extensibility design.And in main control MCU chip+radio receiving transmitting module conceptual design, the user can select different main control MCU to build hardware platform according to the complicacy of system applies, designs flexibly relatively, makes things convenient for system upgrade.In numerous chips that meet the ZigBee standard, selected the CC2420 of TI.Utilize the Wireless Telecom Equipment of this chip development can support the 250Kbps data transmission rate, can realize multi-multipoint quickly networking, the more important thing is, only need few external component, stable performance and power consumption are extremely low, can guarantee the validity and the reliability of short haul connection.
It is the thought of specific application target define program framework that wireless image transmitting software design is adopted in the ZigBee consensus standard.The present invention makes up the application framework of low coupling according to ZigBee appliance protocol stack system structure planning software level, and it can be embedded in the radio visual entrance guard system applies background easily, finishes corresponding function.Therefore, the method for The software layering of the present invention, sub-module design has the following steps:
At first, the driver of design Physical layer comprises parts such as system configuration, SPI mouth, serial ports, radio receiving transmitting module CC2420 and read-write FLASH.The Physical layer driver will be used for hardware is tested.Therefore, the design comes testing hardware reliable, errorless in conjunction with the multiple hardwares debud mode with driver.On the reliable errorless basis of hardware testing, design the more reasonable driver of Physical layer efficiently.By the mode of so mutual validation test, the design finishes hardware testing, and designs Physical layer driver efficiently, gets ready for follow-up wireless image transmission system software design, and reliable bottom layer driving support is provided.
Secondly, transplant MAC layer, NWK layer in the ZigBee protocol stack, design ZigBee wireless image transmission application protocol stack.Transplanting of above-mentioned each layer and debugging are carried out from the bottom to the upper strata successively according to hierarchical structure.Check out for convenience the problem of certain layer of software design and improve the efficient of later stage system software combined debugging, this part is successively in the design process, must guarantee each layer of transplanting can stable operation and this layer and high-level interface reliable in function errorless.Therefore, the test job of this part must be comprehensively, carefully.Subsequently, for image data transmission efficient is provided, the design strides a layer transmission mode based on the image data frame of link establishment mechanism.
At last, design wireless image transfer application object, the complete function of realization wireless image transmission requirement.Application framework among the ZigBee provides access interface flexibly for the application in the ZigBee equipment, can define 240 relatively independent application objects at most, the end points numbering from 1 to 240 of any one object, also have the use of two additional terminal nodes for APSDE-SAP: endpoint number 0 is fixed for the ZDO data-interface; Another one end points 255 is fixed for the data-interface function of all application broadcast datas, and end points 241-254 keeps (expansion is used).The design is configured in wireless image transfer application object on the end points 1, adds other wireless transmission task, the designing requirement of compliance with system extensibility when making things convenient for the new function of follow-up system to design.
Described ZigBee standard definition three kinds of network equipments: PAN Coordinator, Router and End Device, wireless image transmission of the present invention has defined above-mentioned three kinds of equipment equally according to equipment characteristic in using, and these three kinds of equipment have different separately functions, therefore, its main program flow is distinguished to some extent.For the optimizer design, the present invention adopts the mode of conditional compilation to distinguish the various network device function.Meanwhile, in order to improve the response time of wireless image transmission application system, all devices is FFD equipment, and the image data frame transmission is adopted and striden a layer transmission mode based on the image data frame of link establishment mechanism.
The present invention has designed and Implemented ZigBee wireless image transmission application protocol stack with reference to the free protocol stack that Microchip provides.Realized that in this protocol stack striding a layer transmission mode based on the image data frame of link establishment mechanism finishes the image data frame transmission, has effectively improved transfer efficiency.Subsequently, adopt this protocol stack to make up wireless image transfer application object, realized wireless image transmission complete function.This complete function comprises: the network basic function; Network topology structure realizes; Equipment low power consumption control and link wakeup; Employing is striden layer transmission mode based on the image data frame of link establishment mechanism and is carried out image data transmission; In data communication process, all node device handle data communication are unusual, and are overtime etc. as link establishment failure, admission control, image transformation task.
Logical links creates a mechanism and realizes that thought is: when the image data transmission task was arranged, Coordinator sent the link establishment command frame of APL layer, and all routing devices that wake up on this link enter normal operating conditions.If the current routed path that does not have destination node, perhaps Coordinator wakes equipment when failure on the link up, and Coordinator starts in the ZigBee consensus standard route discovery function and sets up logical links.If the stipulated time can not successfully be set up link, Coordinator is unusual with regard to the indication of output error status information.When logical links equipment is waken up and enters normal mode of operation, send link establishment response command frame and inform Coordinator link establishment success, and preserve this link nodes address.When logical links was set up successfully, all routing devices on Coordinator and the link had all been preserved the address of next jumping, had set up the communication link that view data is transmitted.Thus, when receiving image data frame, just can directly transmit routing device by the next hop address of having preserved.
It realizes that thought is to stride layer transmission mode based on the image data frame of link establishment mechanism: if wireless image application object software design meets the requirement of ZigBee consensus standard fully, all data, services are all carried out service manner with application layer in turn to Physical layer and are realized, all will comprise the whole frame header of each layer in each frame image data frame, the view data net load is few.During the relatively large complete image of transmitted data amount, each frame data redundant information is more, has greatly reduced wireless data transmission rate and has increased system power dissipation.For example, comprise the frame head and the control information of 30 bytes in the Frame of ZigBee consensus standard application layer altogether.It comprises:
Frame length: 1 byte; Mac frame head: 11 bytes; Network layer frame head: 8 bytes; APS frame head: 6 bytes; APL frame head: 4 bytes.And each frame data max cap. of Physical layer is 127 bytes.
After employing was striden layer transmission mode based on the image data frame of link establishment mechanism, image data frame directly was transferred to the MAC layer from application layer, saved network layer data frame head and corresponding the processing, had so just greatly reduced the redundant information in the Frame.This mode hypograph Frame frame head can reduce to 16 bytes, only comprises: frame length: 1 byte; Mac frame head: 11 bytes; APL frame head: 4 bytes.Because an image needs the continuous multiple frames transmission, it is just very considerable that design therefore like this improves effect to traffic rate.This mode realizes that image data frame transmission must set up former back end earlier to the logical links between the destination node, promptly adopts the logical links realization thought that creates a mechanism.
In a word, practical application according to gate control system is a background, the present invention proposes the total solution of wireless visible/talk back entrance guard system, mainly ZigBee wireless image transmission application protocol stack and wireless image transmission application hardware and software platform are studied in great detail and design based on the ZigBee technology.The groundwork that the present invention finishes has:
