Appended drawing reference: 101- mechanical floor, 102- are uniformly accessed into layer, 103- abstract service layer, 104- application layer.
Specific embodiment
Referring to Fig.1-3, a kind of access service system being uniformly accessed into equipment of the invention, including mechanical floor 101, uniformly connect Enter layer 102, abstract service layer 103 and application layer 104.
Mechanical floor 101 include it is multiple have respective individual data acquisition mode and by acquisition tidal data recovering enter to be uniformly accessed into layer 102 sensing equipment, sensing equipment includes humidity sensor, humidity sensor, camera, GPS, remote light controller, remote Journey air-conditioner controller, smoke sensor device, shock sensor, remote switch or other sensing detection equipment.Sensing equipment can be adopted With any different type, different vendor, different model equipment.
Being uniformly accessed into layer 102 includes device communication module, functions of the equipments abstract module, data abstraction module and protocol conversion Module, the device communication module are used to communicate to connect with mechanical floor 101;The functions of the equipments abstract module will be for that will set Each sensing equipment of standby layer 101 forms unified abstract equipment by function modeling;The data abstraction module will be for that will set The data of each sensing equipment of standby layer 101 form the abstract data of uniform type by data abstraction;The protocol conversion mould Block is also used to for the proprietary data format of mechanical floor 101 to be converted into publicly-owned data format and passes to abstract service layer 103 The publicly-owned control instruction of abstract service layer 103 is converted into privately owned control instruction and pass to mechanical floor 101 it is corresponding sensing set It is standby.
Functions of the equipments abstract module be used to by the equipment of different type, different vendor, different model by equipment function into Row is abstract.For example, the camera of the A model of manufacturer's first production has the function of real-time streams of taking pictures, check, then picture sensing is taken out Device, real-time flow sensor.Manufacturer's second production Type B number camera have take pictures, recording function, then take out picture sensing Device, video recording sensor.Manufacturer's first production A model camera and manufacturer's second production Type B camera be from different vendor, The equipment of different model, after device abstraction layer, what is obtained is three sensors: photo sensor, real-time flow sensor, Video recording sensor.Different type, different vendor, different model equipment by having reformed into unified pumping after function modeling As equipment.
Data abstraction module be used to by different type, different vendor, different model equipment data carry out type take out As.For example, the temperature sensor of the A model of manufacturer's first production, the temperature value of acquisition can be stored with floating number, be then abstracted The data of floating point type out.Manufacturer's second production Type B number humidity sensor, acquisition humidity value can also with floating number come Storage, accordingly it is also possible to use the data of just now abstract floating point type.Manufacturer's first production A model temperature sensor and The humidity sensor of the Type B number of manufacturer's second production is from different vendor, different type, the equipment of different model, by data After abstract, what is obtained is a type of data abstraction: real-coded GA.
Protocol conversion module is used to carry out protocol conversion, and protocol conversion includes data protocol conversion and command protocols conversion.
So-called data protocol conversion refers to, the proprietary data format of equipment is converted to publicly-owned data format.Publicly-owned data Format is unrelated with device type.Data protocol conversion includes two layers of meaning.Internally it is directed to different type, different vendor, different shaped Number equipment, use the intrinsic proprietary protocol of equipment.Externally for abstract device type, abstract data type, system is used The publicly-owned agreement of the system of one standard.Service system acquires sensor private data from equipment using equipment proprietary protocol, then, will Private data carries out abstract data conversion, then abstract data is supplied to upper layer with publicly-owned agreement and is used.
So-called command protocols conversion refers to, publicly-owned system command is converted to the privately owned control instruction of equipment.Service system System receives the publicly-owned control instruction that application layer 104 issues, and publicly-owned control control instruction is converted to equipment private by protocol conversion layer Some control instructions, control equipment.
Abstract service layer 103 is used to receive the data for being uniformly accessed into the transmitting of layer 102, and is analyzed, handled, stored, will Data after processing are uploaded to application layer 104;It is also used to periodically inquire the equipment control instruction issued from application layer 104, such as Fruit equipment control instruction is the sensing equipment controlled in present networks, i.e., will reach corresponding sensing equipment under equipment control instruction. Abstract service layer 103 include sensing network set up module, sensing equipment management module, data acquisition module, data uploading module, Instructions query module and device control module, the sensing network sets up module, for different type, the difference according to access Manufacturer, different model sensing equipment set up sensing network;The sensing equipment management module for manage sensing network and The sensing equipment being connect with sensing network;The data acquisition module, for acquiring the data abstraction mould for being uniformly accessed into layer 102 The abstract data that block is formed;The data uploading module is used to the data of data collecting module collected being uploaded to application layer 104;The instructions query module is for periodically inquiring the equipment control instruction issued from application layer 104;The equipment control Molding block is used for when the equipment control instruction that instructions query module polls to application layer 104 issue, if equipment control instruction It is the sensing equipment controlled in present networks, i.e., will reaches corresponding sensing equipment under equipment control instruction.
Abstract service layer 103 is provided with the communication interface of standard, including sensor resource uploads interface, data upload connects Mouth, instructions query interface etc..
Application layer 104 is used to show to user sensing data, and passes through application layer 104 to sensing equipment sending device Control instruction.Application layer 104 includes Internet of Things sensing cloud platform or other application.
Access service system of the invention, user can sense cloud platform or other application by the Internet of Things of application layer 104 Control instruction is issued, abstract service layer 103 is then passed to by application layer 104,103 timing of abstract service layer is from upper application layer 104 query facility control instructions, if there is control instruction is the sensing equipment controlled in present networks, then abstract service layer The instruction will be transferred to and is uniformly accessed into layer 102 by 103, be uniformly accessed into layer 102 and be converted to the publicly-owned control control instruction The privately owned control instruction of equipment, is transferred to corresponding sensing equipment respectively.Sensing equipment executes control instruction, acquires the number of needs It according to rear, then deliver the data to and is uniformly accessed into layer 102, the data abstraction module and functions of the equipments for being uniformly accessed into layer 102 are taken out As module is respectively handled device abstract and data abstraction, then the proprietary data format is converted to by protocol conversion module Publicly-owned data format, then abstract data is supplied to by upper layer with publicly-owned agreement and is used, the reception of abstract service layer 103 is uniformly accessed into layer The data of 102 transmitting, and analyzed, handled, stored, the data after processing are uploaded to application layer 104, pass through application layer 104 Internet of Things sensing cloud platform or other application may have access to the data information.
