According to accumulation layer and data presentation layer, the terminal device accesses the equipment access layer in platform of internet of things, institute by MQTT agreement
State basic service layer connection equipment access layer, data storage layer and data presentation layer, the data presentation layer and basic service layer
It is connect by Internet of Things with data display device.
Composition a preferred technical solution of the present invention, the equipment access layer pass through inside basic service layer
The authentication of auth2.0 obtains JWT password, then passes through JWT password access REST API.
Composition a preferred technical solution of the present invention, the basic service layer access data by way of remotely connecting
Library, basic service layer lead to the device data received from equipment access layer, the operational order got from REST api interface
The ORM interface for calling data storage layer is crossed, write-in, the inquiry operation of data are carried out.
Composition a preferred technical solution of the present invention, the data presentation layer uses the design of front and back end separation, described
Basic service layer provides the authentication mechanism and REST api interface of auth2.0, and data presentation layer is recognized by the authentication of Auth.
Card obtains JWT password, and the REST api interface of basic service layer is called to be communicated with basic service layer.
Composition a preferred technical solution of the present invention, the data storage layer use Redis and PostgreSQL technology,
L2 cache of the Redis as PostgreSQL, PostgreSQL by the way of trigger, data it is inserted or updated when
It waits, while inserted or updated to Redis.
Composition a preferred technical solution of the present invention, Redis data save in memory, open AOF persistence function,
It stores data on disk, data can be restored from disk after Redis is restarted.
Composition a preferred technical solution of the present invention, the data presentation layer pass through the long-range clothes in data display device
The working condition of business device real-time display terminal device, client, is managed dimension to the historical data of terminal device, client
Shield, including the addition to terminal device and client, update, delete operation.
Compared with prior art, the beneficial effects of the present invention are:
1, present device access layer is by the way of MQTT server, relatively traditional HTTP connection type, possess it is high-efficient,
The agency's clothes for consuming feature low, that timeliness is high, solving the resource problem of internet of things equipment access bulk device, while using
Business device mode solves the problems, such as that the mono- instance server capacity of MQTT is limited, may be implemented seamless to open up appearance.
2, the design for the double data library that data access layer of the present invention uses, Redis is as cache server, PostgreSQL
As data storage server, the concurrent capability and timeliness of database are improved；Basic service layer is visited by ORM interface simultaneously
It asks data, the safety of data is improved by way of data isolation.
3, basic service layer of the present invention uses auth2.0 authentication, controls access authority, improves the peace of access
Quan Xing；Outside Access is provided using REST api interface, isolated data directly operates, and improves the safety of data.
4, the Distributed Design (equipment access layer, basic service layer, data storage layer, data presentation layer) that the present invention uses
It so that system deployment is more flexible, can be disposed according to system resource, can be deployed on a server, can also divide
It does not dispose on a different server.

Layer 4, the basic service layer 5 connect equipment access layer 4, data storage layer 6 and data presentation layer 7,7 He of data presentation layer
Basic service layer 5 is connect by Internet of Things with data display device 3.
In the present embodiment, it is preferred that the equipment access layer 4 is recognized by the authentication of the auth2.0 inside basic service layer 5
Card obtains JWT password, then passes through JWT password access REST API.
In the present embodiment, it is preferred that the basic service layer 5 accesses database, basis clothes by way of remotely connecting
Layer 5 be engaged in the device data received from equipment access layer 4, the operational order got from REST api interface, passes through calling
The ORM interface of data storage layer 6 carries out write-in, the inquiry operation of data.
In the present embodiment, it is preferred that design of the data presentation layer 7 using front and back end separation, the basic service layer 5
The authentication mechanism and REST api interface of auth2.0 are provided, data presentation layer 7 is obtained by the authentication of auth2.0
JWT password calls the REST api interface of basic service layer 5 to be communicated with basic service layer 5.
In the present embodiment, it is preferred that the data storage layer 6 uses Redis and PostgreSQL technology, Redis conduct
The L2 cache of PostgreSQL promotes the performance of database, reduces the demand to IO, and PostgreSQL uses the side of trigger
Formula, when data are inserted or updated, and meanwhile it is inserted or updated to Redis.
In the present embodiment, it is preferred that Redis data save in memory, open AOF persistence function, data are saved
Onto disk, data can be restored from disk after Redis is restarted, higher data can be brought to pacify using AOF persistence
, there is delay machine and will not destroy the content having been written into ensure that data reliability in writing process in Quan Xing.
In the present embodiment, it is preferred that the data presentation layer 7 is real-time by the remote server in data display device 3
Display terminal, client working condition, maintenance is managed to the historical data of terminal device, client, including right
The addition of terminal device 3 and client, update, delete operation.
System flow of the invention are as follows:
1. all service needs of this system are deployed in the cloud platform of public network IP, configuration equipment access layer, configuration Redis,
Start after the long-range connection account number cipher of PostgreSQL；The equipment access service of starting specified quantity on demand, configuration MQTT ginseng
Number is used for the preposition verifying of equipment access layer；The forwarding of equipment access service is configured, starting device accesses agency service；Basis clothes
Being engaged in, layer configures MQTT access parameter, equipment access layer connects account, password, database D B；Configure the key of auth2.0, starting
Basic service layer；The configuration infrastructure service of data presentation layer remotely connects account, password, starts.
2. on-site terminal equipment and equipment access layer establish connection, proxy server receives connection request, equal according to load
Weighing apparatus is forwarded to MQTT server, is verified by dynamic key, if failed service device abandons data, closes connection；Infrastructure service
Layer establishes connection by network and data access layer and realizes data communication, after being successfully established connection, what basic service layer received
Data all pass through data access layer ORM interface and are managed maintenance；Data presentation layer is established by network and basic service layer to be connected
Realization data communication is connect, basic service layer verifies connection by auth2.0 when establishing connection, data exhibition after good authentication
Show that layer is managed maintenance to equipment, client data in such a way that REST api interface calls.
3. data are actively reported to data access server by terminal device, preposition access proxy server turns data
It is dealt into MQTT server, MQTT server is data-pushing to the basic service layer of registration, and basic service layer is the number received
According to write-in database, data presentation layer checks the data of terminal device in such a way that REST api interface calls and analyzes exhibition
Show.
4. user operates equipment on data presentation layer, the instruction of operation is sent out by way of REST api interface
Basic service layer is given, basic service layer receives instruction, is pushed to MQTT server, and MQTT server passes through proxy server
Instruction is pushed to the terminal device of registration.
