Description
Technical field
The present invention relates to a kind of product information traceability system, relate in particular to a kind ofly to production, dispensing, the information of carrying out is reviewed the system with Antiforge inquiry in the sale.
Background technology
Electronic tag is radio frequency discrimination RFID (Radio Frequency IDentification) technology; Radio frequency identification; Be a kind of communication technology, can discern specific objective and read and write related data, and need not to set up machinery between recognition system and the specific objective or optics contacts through radio signals.REID (Radio Frequency Identification; Abbreviation RFID); Be a kind of automatic identification technology that begins to rise the nineties in 20th century, REID is the technology that the information utilizing radiofrequency signal to pass through space coupling (alternating magnetic field or electromagnetic field) the contactless information transmission of realization and pass through to be transmitted reaches identifying purpose.
It can discern specific objective and read and write related data through radio signals, and need not to set up machinery between recognition system and the specific objective or optics contacts.
Ultimate principle from the information transmission; REID in low-frequency range based on transformer coupled model (energy delivery between elementary and secondary and signal transmission), at high band based on the space coupling model of radar detection target (radar emission electromagnetic wave signal run into target then carry target information return radar receiver).
After label gets into magnetic field; If receive the special radiofrequency signal that reader sends, just can rely on the energy that induction current obtained to send out the product information (being PassiveTag, passive label or passive label) that is stored in the chip; The signal that perhaps initiatively sends a certain frequency (is ActiveTag; Active label or active tag), after reader reads information and decoding, deliver to CIS and carry out the relevant data processing.
The Mesh network i.e. " wireless mesh network ", and it is a wireless multi-hop network, is by the adhoc network development, is to solve one of " last kilometer " key of problem technology.In the process of picture next generation network evolution, wireless is an indispensable technology.Wireless mesh can be communicated by letter with other network cooperating.Be the network architecture that can constantly expand dynamically, two equipment all can keep wireless interconnected arbitrarily.
The Mesh wlan network is more stable than single-hop networks, and this is that the performance of network performance is not only to rely on certain node because in data communication. in traditional single-hop wireless network; If fixing AP breaks down, all wireless devices all can not communicate in this network so. and in the Mesh network, if the AP of certain node breaks down; It can select an AP to communicate again again; Data still can arrive the destination at high speed. and say that from physical angle radio communication means that communication distance is short more, the effect of communication can be good more. because of growth along with communication distance; Wireless signal not only can be weak but also can the phase mutual interference; Thereby reduce the efficient of data communication. and in the Mesh network, be with the wireless network connection replacement connection of long distance in the past of weak point of a rule, thereby guarantee that data can make the installation deployment of WLAN with two-forty quick transmission .Mesh technology between node; The network capacity extension is convenient. and many producers have all released the Mesh product of feature richness; Thereby make and dispose extensive operation level wireless MAN and become possibility.

1, wireless aps
Wireless aps (AP, Access Point, wireless access node, session point or access bridge) not only comprises simple property WAP (wireless aps), is the general designation of wireless router kind equipments such as (containing radio network gateway, wireless bridge) too.
Along with popularizing of wireless router, present case as there not being special explanation, generally still only is interpreted as simple property wireless aps with the wireless aps of being called down, distinguishes to show with wireless router.It mainly provides wireless stations to cable LAN with from the visit of cable LAN to wireless stations, and the wireless stations in the access points coverage can intercom through it mutually.
Simple property wireless aps is exactly a wireless switch, only provides the function of a wireless signal transmission.The principle of work of simple property wireless aps is that network signal is sent through twisted-pair feeder, and the compiling through the AP product becomes radio signals with electrical signal conversion and sends out, and forms the covering of wireless network.According to different power, it can be realized in various degree, the network coverage of different range, and the largest coverage distance of general wireless aps can reach 300 meters.
Most simple property wireless apss itself do not possess routing function, and the server capability that comprises DNS, DHCP, Firewall all must have independently route or computing machine accomplish.Present most wireless aps all supports multi-user's (30-100 platform computer) to insert, data encryption, and functions such as many speed transmission, in family, office, a wireless aps just can realize the wireless access of all computers.
Simple property wireless aps also can be done necessary control and management to the computer that wireless network card is housed.Simple property wireless aps promptly can be passed through 10base-T (WAN) port and directly link to each other with the ADSLMODEM or the CABLE MODEM (CM) of built-in routing function, also can have access to spider lines again through switches/hubs, broadband router in use.
Wireless aps is similar with wireless router, and the coverage of IEEE 802.11b and IEEE 802.11g is indoor 100 meters, outdoor 300 meters according to consensus standard itself.This numerical value only is theoretical value, in practical application, can run into various barriers, and is wherein minimum to the influence of wireless signal with glass, plank, plaster wall, and concrete wall and iron are to the shielding maximum of wireless signal.So common actual usable range is: indoor 30 meters, outdoor 100 meters (not having barrier).Therefore, as link WAP important in the wireless network, radio network gateway wireless aps (Access Point) just, its effect is similar to the hub in the cable network commonly used.
2、MESH
Wireless Mesh netword (based on wireless mesh network) is also referred to as " multi-hop (multi-hop) " network, and it is a kind of and the diverse novel radio network technology of conventional wireless network.In traditional wireless lan (wlan); Each client all visits network through a Radio Link that links to each other with AP; The user must at first visit a fixing access point (AP) if intercom mutually, and this network structure is called as single-hop networks.And in wireless Mesh netword, any wireless device node can be simultaneously as AP and router, and each node in the network can send and receive signal, and each node can carry out direct communication with one or more peer node.
The largest benefit of this structure is: congested if nearest AP causes owing to flow is excessive, data can be routed to a less adjacent node of communication flows automatically again and transmit so.The rest may be inferred, and packet can also continue to be routed to nearest with it next node and transmit according to the situation of network, till arriving the final destination.Such access mode is exactly the multi-hop visit.
Compare with traditional switching network, wireless Mesh netword has removed the wiring demand between the node, but still has redundancy scheme that distributed network provides and routing function again.In wireless Mesh netword, if add new equipment, it is just passable only need to connect with the mains simply, and it can carry out self-configuration automatically, and confirms best multi-hop transmission path.When interpolation or mobile device, network can be found change in topology automatically, and adjusts the communication route automatically, to obtain the most effectively transmission path.
Five big advantages of Mesh network:
Compare with traditional WLAN, wireless Mesh netword has several incomparable advantage:
1. dispose fast and be easy to install.Installing M esh node is very simple, and equipment is taken out in packing box, has connected with the mains just.Owing to greatly simplified installation, the user can be easy to increase coverage and the network capacity that new node enlarges wireless network.In wireless Mesh netword, not that each Mesh node all needs wire cable to connect, what this was it with wired AP maximum is different.Therefore the design object of Mesh is exactly the quantity of wireline equipment and wired AP to be reduced to minimum, greatly reduces TCO and set-up time, and only the cost savings brought of this point are exactly considerable.The configuration of wireless Mesh netword is identical with traditional WLAN with other network management functions, and the user uses the experience of WLAN can be easy to be applied on the Mesh network.
2. non line of sight transmission (NLOS).Utilize the Wireless Mesh technology can be easy to realize the NLOS configuration, therefore have a wide range of applications with the public place outdoor.There is the user of direct sighting distance to receive wireless signal earlier with transmitting station, and then gives the user of non-direct sighting distance the signal forwarding that receives.In this manner, signal can select optimal path constantly to jump to another user from a user automatically, and the final targeted customer who arrives no direct sighting distance.Like this, the user who has a direct sighting distance is actually the proximal subscribers that does not have direct sighting distance provides the WiMAX access function.Wireless Mesh netword can non line of sight the characteristic of transmission expanded the application and the coverage of WiMAX greatly.
3. robustness.Realize that the network robustness usual way is to use multi-router to transmit data.If certain router breaks down, information is transmitted through backup path by other routers.The Mesh network is more healthy and stronger more than single-hop networks, because it does not rely on the performance of some single nodes.In single-hop networks, if some nodes break down, whole network is just paralysis thereupon also.And in the Mesh network structure, because each node all has one or several to transmit the path of data.If nearest node breaks down or is interfered, packet will be routed automatically to backup path and proceed transmission, and the operation of whole network can not be affected.
4. structure is flexible.In single-hop networks, equipment must sharing A P.If several equipment are wanted accesses network simultaneously, just possibly produce traffic congestion and cause the travelling speed of system to reduce.And in multihop network, equipment can be connected to network simultaneously through different nodes, therefore can not cause the reduction of system performance.The Mesh network also provides bigger redundancy scheme and traffic load equilibrium function.In wireless Mesh netword, each equipment all has a plurality of transmission paths to use, and network can be according to the traffic load situation of each node allocate communications route dynamically, thereby has avoided the traffic congestion of node effectively.And present single-hop networks can not dynamically be handled the overload problems of Communication Jamming and access point.
5. high bandwidth.The physical characteristics of radio communication has determined the shorter high bandwidth that just obtains more easily of the distance of communications, because along with the increase of wireless transmission distance, various interference cause the factor of loss of data to increase with other thereupon.Therefore select shortly to jump that to transmit data will be a kind of effective ways that obtain the higher network bandwidth through a plurality of, and this Mesh network advantages place just.
In the Mesh network, a node can not only transmit and reception information, can also serve as router near node forwarding information it, and along with the increase with possible number of paths that interconnects of more nodes, total bandwidth also increases greatly.
In addition, because each short transmission range of jumping is short, transmission data desired power is also less.Since multihop network uses lower-wattage with the node of data transmission to vicinity usually, the wireless signal between the node disturbs also less, and the channel quality and the channel transport efficiency of network improve greatly, thereby can realize higher network capacity.Such as in highdensity urban network environment, the Mesh network can reduce the phase mutual interference of the neighboring user of using wireless network, improves the utilization ratio of channel greatly.
