Description
Technical field
The utility model relates to a kind of technology of Internet of Things field, specifically a kind of Wi ?Fi Internet of Things heterogeneous network realize framework.
Background technology
Internet of Things, i.e. InternetOfThings (IoT).Internet of things equipment can be various information sensor and controller, also can be various intelligentized household electrical appliance.Internet of things equipment is accessing Internet in several ways, and a huge network of formation, achieves the Internet from people to the extension of thing.
Wi ?Fi Internet of Things access way be most widely used, cost is minimum, one of Internet of Things access way that extensibility is best.Usually, Wi ?Fi internet of things equipment directly by Wi ?Fi access point (Wi ?FiAccessPoint, also claim Wi ?Fi focus or wireless router) access network.But, most Wi ?Fi internet of things equipment function more single, exchanges data amount is relatively little.Many times, Wi ?Fi internet of things networking time, Wi ?between Fi internet of things equipment space length comparatively large, device distribution density less (mutually do trunking can not), and in most cases these device data rate requirement are lower.Therefore can cause in some application scenarios, traditional Wi ?the Fi link transmission physical distance situation that reaches or overstep the extreme limit.Or Wi ?Fi Internet of Things covering space in channel situation complicated time, for broad frequency band two-forty Wi ?Fi signal, alter into when the multidiameter delay of relatively long wireless channel or channel traditional Wi ?Fi link data transfer poor effect.
For solving the problem, generally, in Wi ?Fi internet of things networking process, the extra Wi ?Fi internet of things equipment for dispersion distribution or channel conditions difference is needed to configure a considerable number of trunking in suitable distance or position.But this settling mode can increase Wi ?the implementation complexity of Fi Internet of Things, greatly increase network cost and maintenance difficulties.
Through finding the retrieval of prior art, open (bulletin) the day 2013.01.16 of Chinese patent literature CN202679655U, disclose a kind of multiband isomeric compound networking gateway device, it relates to field of wireless data communication, main control unit 1 transplants built-in Linux operating system, transplanted multiple Internet of Things communication protocol in system, support IEEE802.15.4 standard, IEEE802.15.4c standard, ISO/IEC18000 ?4 standards, ISO/IEC18000 ?7 standards.Support multiband, interconnecting of the internet-of-things terminal equipment of various protocols and wide area IP communication network and mobile communications network.The awareness apparatus data access simultaneously can supporting multiple frequency range, various protocols is compared relative to more existing wireless sensor network gateway equipments; Multiple Internet of Things network layer access way can be provided, easy to use and flexible, achieve thing network sensing layer multi-band frequency multi-protocol awareness apparatus access Internet of Things network layer, realize the object that sensing region multiband node device and external network directly carry out exchanges data.But the prior art does not solve the problem of expanding the coverage area in the Internet of Things of single-protocol, realize complicated, cost is higher.
Utility model content
The utility model is for prior art above shortcomings, propose a kind of Wi ?Fi Internet of Things isomery realize framework, the long distance of needs lay low-density Wi ?Fi internet of things equipment time, adopt reduce baseband rate Wi ?Fi Internet of Things subnet, to expand the signal effective coverage range of this subnet, and by Wi ?Fi Internet of Things bridging device and standard full rate Wi ?the equipment of Fi Internet of Things carry out exchanges data.
The utility model is achieved through the following technical solutions:
The utility model comprises: be connected with Internet of Things possess full baseband rate Wi ?Fi link wireless router, with this wireless router by the bridging device of full baseband rate wireless connections and/or Wi ?Fi equipment and with described bridging device by reduce baseband rate wireless connections Wi ?Fi equipment.
Described bridging device comprises: clock switching controller and adjustable mac controller, digital modulation and demodulation baseband chip, digital-to-analogue/analog to digital converter and the Analog Baseband chip of sampling rate, wherein: clock switching controller, by controlling the work sampling rate of the adjustable MAC of sampling rate and each baseband module, realizes the variable baseband rate of bridging device under the prerequisite not changing any physical layer modulation mode and mac-layer protocol details in circuit realiration.
Described reduction baseband rate, preferably refers to that reduced-sample-rate is to 1/2 and 1/4 of the full sampling rate of standard.
Described bridging device includes but not limited to: Wi ?Fi access point apparatus, carry out the internet of things equipment etc. of gauged distance transfer of data.
The Wi of described reduction baseband rate wireless connections ?Fi equipment include but not limited to: environmental monitoring Internet of things device, outdoor Internet of Things lighting apparatus etc. that distribution distance is far away.
The Wi of normal full baseband rate ?Fi equipment, time lower, the order of modulation of data rate is less over the wireless channel, transmission range is larger.Therefore, in order to improve signal transmission distance, and adopt and fall the Internet of Things subnet of baseband rate, it is the most meaningful that the basis of small data rate falls baseband rate.
Baseband rate as complete in 1Mbps, through falling the sampling rate to 1/2 (i.e. 0.5Mbps) of MAC module and baseband module, then practical base-band speed is corresponding is down to 1/2, signal bandwidth is down to during full baseband rate 1/2, the performance of antagonism radio channel multi-path decline is improved, and the physical distance of Absorbable organic halogens transmission data strengthens.
Technique effect
Compared with prior art, the utility model can significantly improve Internet of Things coverage, and antagonism severe channel conditions, strengthens the stability of Signal transmissions; Realize simple simultaneously, do not need extra device, also do not need to make very large amendment to the circuit realiration of existing internet of things equipment.
