Description
Technical field
The utility model relates to a kind of Network Access Point, and particularly a kind of wireless network access point based on Bluetooth technology belongs to communication technical field.
Background technology
21 century is informationalized century.Along with the fast development of computer industry and information industry, the raising of living standards of the people, intelligent building is flourish and become the development main flow of new century building industry all over the world.For emerging modern intelligent residential district, just formulated the comprehensive wiring scheme of each subsystem at first stage of construction, but for old building, the dwelling house of perhaps having fitted up, the difficulty that is transformed into the intelligent residential district maximum is exactly a wiring problem, and utilizes wireless communication technology just to provide a good solution for this type of problem.The scheme that solves the network wireless accessization mainly contains Bluetooth technology, 802.11 technology and HomeRF technology.Compare with the HomeRF technology with 802.11, the advantage of bluetooth is: it provides a kind of wireless solution of economy, advantages such as it is convenient, reliable, easy use.In numerous wireless solutions of attempting to meet the demands, having blue tooth wireless technology only has enough hope can win the extensive support of computer and Communications Market manufacturer.
Summary of the invention
The purpose of this utility model is to provide a kind of wireless network access point based on Bluetooth technology, can pass through network interface (RJ45) links to each other with the sub-district local area network (LAN), an other end links to each other by other outer bluetooth equipments of Bluetooth technology and local area network (LAN), thereby realizes the shared of resource between these bluetooth equipments and the intelligent residential district local area network (LAN).
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of wireless network access point based on Bluetooth technology, it is characterized in that: described wireless network access point comprises controller, bluetooth baseband chip and other interface circuits, memory device, one end of access point links to each other with the sub-district local area network (LAN) by the network port, and the other end utilizes other outer bluetooth equipments of Bluetooth technology and local area network (LAN) to link to each other.
Wireless network access point based on Bluetooth technology described in the utility model can be realized sharing of resource between bluetooth equipment and the intelligent residential district local area network (LAN), has advantages such as good flexibility, high cost performance, low electromagnetic radiation, low-cost input, high stability and high reliability, market prospects are wide.
Description of drawings
Fig. 1 is the system construction drawing of the wireless network access point based on Bluetooth technology described in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Being applied to intelligent residential district wireless network access with the utility model is example.As shown in Figure 1, intelligent residential district blue tooth radio network access point solution is made of two parts, bluetooth local area network access point (LAP) and data terminal equipment (DT).
LAP requires and can be required to realize PPP server capability, protocol conversion (gateway) function by other Bluetooth mobile terminals function of looking for, connecting and communicating by letter with it for future reference.
DT requires the function can finish the equipment of searching, check COS, connect, can finish anti-function of asking local area network (LAN) and Internet, and can realize the function of communicating by letter between the DT.
LAP provides the method for a kind of wireless access sub-district local area network (LAN) for other bluetooth equipments (DT).The key point that realizes this solution is exactly bluetooth local area network access point (LAP).The key point that realizes blue-tooth intelligence sub-district wireless solution is exactly bluetooth local area network access point (LAP).LAP provides the method for a kind of wireless access sub-district local area network (LAN) for bluetooth equipment.This product is adopted the development approach of embedded system, makes final finished product be similar to the network printer and equally is independent of main frame.LAP is the interface of local area network (LAN) between inside and outside, the one end links to each other with the sub-district local area network (LAN) by network interface (RJ45), an other end links to each other by other outer bluetooth equipments of bluetooth and local area network (LAN), thereby realizes the shared of resource between these bluetooth equipments and the intelligent residential district local area network (LAN).Be more specifically to LAP itself, in brief, LAP mainly is made up of controller and bluetooth baseband chip and other interface circuits, memory device etc.Higher layer applications and control program via controller commander Bluetooth chip are realized corresponding access point function according to set agreement work.
Model is cut, discussed in the access point system according to bluetooth LAN Access Profile's (local area network (LAN) insert application model standard), and the bottom communication between DT and the LAP has adopted short-distance wireless communication new technology one Bluetooth technology.Use the exploitation frequency range of 2.4GHz.Under point-to-point situation, DT is as main equipment, and IAP is as slave unit, and the two forms micro bluetooth network.(under the situation of point-to-multipoint, relate to main one problem from conversion, IAP will be transformed into main equipment by slave unit.)
According to the regulation of LAN Access Profile, use the connection of PPP over RFC0MM between the DT-LAP.PPP is a kind of widely used access network technology.Functions such as it belongs to the data link layer of OSI, and authentication is provided, and encrypts, and data compression and multi-protocols are multiplexing.LAP is as PPP Server, and DT is as PPP Client, and the two is set up PPP/RFCOMM/L2CAP and connects.
The main function of access point is to realize that terminal visits local area network (LAN) by LAP, and then visit Internet, so the function of network is most important.Set up after the PPP connection, between DT and LAP, just consulted the pair of IP address.The transmission of IP data can have been carried out.In native system, the effect of LAP is just as a gateway, and it is sent to the IP/PPP bag that receives on the local area network (LAN).Therefore just need be in the enterprising walking along the street of LAP by configuration, same, the IP/PPP packet from LAN to DT also needs to carry out such routing configuration.
Consider practical application, this product adopts Embedded development approach, and making final products is the embedded product that is independent of main frame.The development and application platform is based on real-time embedded operating system Vx Works, and program is moved after downloading to the Target Board that has microprocessor (Power PC).
