Drawings
Other features, objects and advantages of the present invention will become more apparent upon reading of the detailed description of non-limiting embodiments, made with reference to the following drawings, in which:
fig. 1 is a schematic structural diagram of an internet of things system according to an embodiment of the present invention;
Fig. 2 is a schematic structural diagram of another internet of things system according to an embodiment of the present invention.
Detailed Description
Referring to fig. 1 and 2, the present embodiment discloses an internet of things system deployed in a server on a public network address, the system comprising:
the Internet of things equipment access unit is used for receiving data uploaded by a plurality of Internet of things equipment and preprocessing the data;
The PaaS platform access unit is used for sending the data uploaded by the Internet of things equipment or the preprocessed data to the PaaS platform and requesting service from the PaaS platform;
and the client access processing unit is used for responding to the access request based on the public network address and requesting service from the PaaS platform according to the access request.
Fig. 1 is a schematic diagram of a domestic PaaS platform, and fig. 2 is a schematic diagram of a foreign PaaS platform.
According to the structure shown in fig. 1 and 2, through the internet of things system, a barrier and isolation function can be achieved among the client server, the internet of things equipment and the PaaS platform, so that the client server or the terminal does not need to expose own IP address, the client server can be prevented from being attacked, the internet of things equipment itself does not know the address of the server, and even if the internet of things equipment adopts a non-confidential mode to transfer data, the client server address exposure can not be caused. Meanwhile, as the client server is not directly connected with the PaaS platform, the Internet of things system of the scheme can be connected with the PaaS platform by adopting a special line, so that lower flow cost can be strived for the client, and the communication speed and the connection stability are convenient and more enhanced. In addition, the Internet of things equipment can be accessed to the system through directional flow, so that the use cost of a user can be saved.
In some embodiments, the internet of things device access unit communicates with a plurality of the internet of things devices based on an MQTT protocol;
the preprocessing of the data comprises the following steps:
at least one of deleting useless or duplicate data, performing numerical conversion on the data, or rejecting abnormal data.
In the embodiment, the system communicates with each Internet of things system based on the unified MQTT protocol, so that the workload of protocol matching development of clients can be reduced. In addition, the data of the Internet of things equipment are subjected to simple data cleaning and data conversion, so that on one hand, the communication traffic with the PaaS platform can be reduced, and the data conversion can be configured in the Internet of things system based on the needs of users, so that the Internet of things equipment does not need to independently develop the data conversion, and the acquired data can be directly uploaded. For example: the temperature integer data of 207 is read by the internet of things equipment, and the data is obtained by dividing 20.7 by 10. The data read from the three registers need to be converted by the formula to be the final data: a 0.7+b 1.3+c/100. The equipment end of the Internet of things needs to integrate too many operations, so that the software multiplexing degree is reduced.
Through the description, all the devices of the internet of things are uniformly connected to the same system. According to the unified Internet of things system, the large PaaS platform interfaces are in butt joint according to the PaaS selection of the client. For all the Internet of things devices accessing the system, only one Internet of things platform is seen, and the interference of the real PaaS platform is shielded. The leasing and account management of the PaaS platform are all carried out by the unified Internet of things system.
The system unifies various complex Internet of things protocols into an MQTT protocol (of course, other Internet of things protocols can be unified). The Internet of things equipment does not need to integrate various other protocols, so that development difficulty is reduced, and meanwhile, the software multiplexing degree is improved.
After the platform interface and the protocol are unified, the system provides the SDK used by android, linux and the singlechip. The internet of things device does not need to care about details of specific links, registration, etc., but rather care about implementation in other business logic.
The system unifies the Internet of things platform, and meanwhile, the Internet of things flow pool is purchased from an operator, and the Internet of things card is also provided. Still further, dedicated traffic may be purchased from the operator. Because the internet of things equipment only accesses the address of the public network, the cost of the traffic of the internet of things equipment can be further reduced by introducing the special traffic.
For a foreign server, the unified Internet of things platform also establishes a dedicated data channel from an operator. Since the account numbers of the clients are uniformly established by the system, a server of the region, such as japan, singapore, or korea, can be selected. Thus, the general 2 special lines can cover the connection of 4 main foreign PaaS platforms. The domestic Internet of things equipment is connected with a domestic deployed unified Internet of things platform, so that the system agent forwards data to a foreign server. This speed is much faster and much more stable than if the device were directly connected to a foreign server.
The client can build the platform by himself, and the connection address of the platform is informed when the Internet of things equipment is used, so that the position of the server is exposed. If encryption is not done, the security is not guaranteed. In particular, without the service of acting as a reverse proxy, all the background and databases are located on the same server, which is easy to cause greater loss. The unified internet of things platform only carries out the work of data proxy, and the database function does not exist, so that the risk of losing and revealing the client data is avoided. Meanwhile, the unified Internet of things platform agent is used for connecting a real background system, so that the connection address of the background is not exposed. All the safety work is ensured by the unified internet of things platform. The background design of the client can be ensured safely, or the difficulty of the design is greatly reduced.
According to the embodiment, the numerical calculation of the edge terminal diversity is transferred to the unified Internet of things system. According to different customer requirements, before each data is uploaded, javaScript codes are added for operation, and after final data is obtained, data forwarding is performed.
In some embodiments, the PaaS platform access unit accesses the PaaS platform based on a private line across the country. The number of the cross-country private lines is at least two, and the PaaS platform access unit is connected with the cross-country substation server through the cross-country private lines and then is accessed to the PaaS platform. And the two transnational substation servers connected by the transnational private line are mutually backed up.
As can be seen from the description in the previous embodiments, only two cross-country substation servers and two dedicated lines need to be deployed to access several mainstream PaaS platforms and complete redundant backups.
In some embodiments, the client access processing unit is further configured to:
And responding to the configuration request based on the public network address, and distributing resources and configuration service functions in a PaaS platform resource pool for the terminal of the configuration request. In this embodiment, because the present internet of things system shields the differences between PaaS platforms, that is, the present system may form a resource pool by purchasing PaaS resources, and then implement PaaS services by allocating resources from the resource pool when providing services for clients.
The Internet of things equipment accesses the Internet of things equipment access unit through the directional flow corresponding to the public network address. Because the system is deployed on a certain fixed public network address, the communication charge can be greatly reduced by purchasing the directional flow.
The data sent by the internet of things equipment to the internet of things equipment access unit are encrypted data, and the internet of things equipment access unit decrypts the encrypted data based on the decryption algorithm to obtain the original data. The scheme can improve the security performance of the scheme based on encrypted communication.
And in the Internet of things equipment, the SDK or the communication protocol library is selected based on the chip type and the operating system to communicate with the Internet of things equipment access unit. The preprocessing of the data is realized based on JavaScript codes.
And the Internet of things equipment is to be successfully docked with a certain Internet of things platform. Firstly, a proper communication protocol library or a version of the SDK is selected according to the type of the device chip and an operating system. And then according to the support of the platform or the requirements of clients, the task writing of registration, connection and data reporting under different protocols is solved. The repeatability and fragmentation of the development work of the Internet of things equipment are caused. Such as: and the android device of the ARM is provided with a CoAP protocol library for connecting with the development of the Azure platform. And installing an Http protocol library on the windows equipment of the X86 to connect with the development of the China mobile platform. MIPS's Linux equipment installs MQTT protocol library to connect with the Arian cloud, etc.
It will be appreciated that in the above embodiment, the protocol is mainly MQTT mode, and HTTP may be used if necessary. Therefore, only the connection flow aiming at the system is needed to be realized, and the access flow of other large platforms is responsible for completing the butt joint by the system. Meanwhile, no matter which target platform is, only one library and one SDK need to be introduced on the equipment, and a developer only needs to develop one App and become familiar with one set of rules, so that the butt joint work of a plurality of platforms can be completed.
In summary, the internet of things device access unit of the system accesses the internet of things device and preprocesses data, compared with the prior art, the internet of things device does not need to directly access a server and a background built by a client, so that the risk of exposing and attacking the address of the client is reduced, meanwhile, the internet of things access unit can reduce the hardware calculation difficulty of the client side by preprocessing the data, the large-scale deployment is more convenient, the client access processing unit of the system is based, the client only needs to access the system, can be connected to the PaaS platform through the system, and can not need to expose the IP address of the client to the outside, thereby reducing the risk of data leakage and attack, and the client only interfaces the system, and the system shields the difference between the PaaS platforms through the PaaS platform access unit, thereby reducing the development difficulty of the client.
It will be appreciated that computer program code for carrying out operations of embodiments of the present invention may be written in one or more programming languages, including an object oriented programming language such as Java, smalltalk, C ++ and conventional procedural programming languages, such as the "C" programming language or similar programming languages. The program code may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the case of a remote computer, the remote computer may be connected to the user's computer through any kind of network, including a Local Area Network (LAN) or a Wide Area Network (WAN), or may be connected to an external computer (for example, through the Internet using an Internet service provider).
