The multi-domain layered connection type multi-domain Internet of things architecture divides an Internet of things platform into a central domain and a plurality of domains, and when the domains join or leave a cluster, information needs to be sent to the central domain, so that when the domain is visited, the central domain can perform corresponding processing; at ordinary times, interaction is not carried out between the subdomains and the central domain, and the subdomains and the central domain are autonomous respectively.
When two or more domains need data interaction or cooperation, addressing is carried out according to the unified identification, a service request is sent to an identification management center, the management center to be identified returns request information and needs a block chain authority center to carry out authority verification, interaction or cooperation can be carried out only after verification, and a cooperation result is returned.

s202: the service security is cooperated, each domain which normally provides the service registers the service provided by the domain to the central domain for external calling; each developer subscribes the service required by the developer and records the authority information on a block chain for authority verification when the service is accessed; when service fusion is needed, responding services are firstly called from each domain, and then collaboration is performed through a service collaboration algorithm.
The application of the principles of the present invention will now be described in further detail with reference to the accompanying drawings.
The multi-domain Internet of things platform provided by the embodiment of the invention comprises a unified identification management center, a central domain management center, a block chain authority management center and a cloud platform monitoring center. The unified identification management center is used for carrying out unified management on domain, gateway, node, service and data identification, such as new addition, modification, update and deletion; the central domain management center is used for activating the new domain, judging the legal condition of each domain, preventing illegal domains from being added into the cluster, and verifying the authority of multi-domain cooperation; the block chain authority management center is mainly used for authority verification of data cross-domain sharing and service collaborative authority verification; and the cloud platform monitoring center is used for monitoring the health conditions of all domains of the whole cluster and carrying out unified management, control and maintenance. The relationship among the modules is shown in fig. 5, the domain-divided and center management is star-shaped, and the cloud platform monitoring center is used for monitoring the healthy running condition of the whole domain cluster in real time so as to perform unified management and control. As shown in fig. 6, when the domain provides service for the first time, it needs to perform activation authentication to the central domain, and if the activation authentication passes, the service is provided normally, otherwise, the service is reactivated after failing. When the server is started each time, the central domain is required to carry out activation verification, if the verification is passed, the service is normally provided, otherwise, the service cannot be provided. When the subzones can not provide service normally or are abnormal, the message is required to be sent to the central zone and broadcasted by the center, and when other zones send requests to the zone, the central zone judges whether other zones provide service or refuse to provide service. The identification part is shown in fig. 3, the identification is divided into a domain identification, a gateway identification and a node identification, 11 bits of the domain identification are composed of an identification type and a domain code, and the identification type is 2; the 19 bits of the gateway identification are composed of an identification type, a domain code and a gateway code, and the identification type is 1; the 25 bits of the node identification are composed of an identification type, a domain code, a gateway code and a node code, the identification type is 0, and the identifications are uniformly expressed by ASCII. The identification type occupies one bit, the identification node is a gateway, 0 represents a node, 1 represents a gateway, 2 represents a domain, 3-9 is reserved for subsequent expansion, the domain code occupies 10 bits, the gateway code occupies 8 bits, and the node code occupies 6 bits. As shown in fig. 4, the block chain authority management center maintains a block for each domain, the whole cluster forms a block chain, and when an external domain requests the local domain, authority verification is performed here, and if and only if both static authority verification and dynamic authority verification pass, interaction can be performed, otherwise, illegal access is recorded, and an exception model is continuously perfected.
The invention also relates to cooperation among multiple domains, which mainly comprises data cross-domain sharing and service cooperation.
As shown in fig. 7, a data sharing process among multiple domains is shown, when data sharing is required among multiple domains, firstly, according to an identifier of each data itself, an identifier management center queries detailed information of a domain where the identifier is located, then, a request is directly initiated to a target domain M, the target domain M requests a block chain authority management center, the authority management center queries a block created by the domain M, performs authority verification, and if the block chain authority management center passes the block chain, performs data sharing, and returns request data; otherwise, no response is made, and the illegal request is recorded to complete the abnormal model.
As shown in fig. 8, a service cooperation process among multiple domains is identified, when a user needs a composite service, a request is submitted to a central domain, the central domain first decomposes the request into a plurality of atomic services, then locks information of a domain where the atomic service is located according to an identifier of each atomic service, then requests services from the central domain to each domain in sequence, each domain performs authority verification to a block chain authority verification center, if all domains pass through, a service cooperation algorithm is performed in the central domain to complete service cooperation, then an execution result is returned to a caller to complete service cooperation, otherwise, service cooperation fails, and no response is given.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
