All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
For a block chain system with multiple central accesses, due to the fact that nodes are numerous, different central system environments are inconsistent, network conditions are different, and geographic distribution between the center and the platform is achieved, manual operation and maintenance of the system are complex and prone to errors, a good multi-center management interface can provide rich management functions, operation and maintenance of users are facilitated, a network structure is simple as much as possible, and operation and maintenance personnel can deploy easily.
The implementation of the embodiment of the invention is divided into two parts, namely management platform side implementation and center side implementation. Opening a port to the central side after the management platform side is successfully implemented; in the implementation of the center side, an open port and an IP (Internet protocol) of the management platform side are configured in a configuration file, and after the implementation is successful, the center is accessed to the management platform side in a network connection mode. The management platform and the center are in a relationship of 1.
The hub may be implemented and deployed on a variety of types of operating systems within the present example, such as Microsoft's win server 2008, win server 2012, various LINUX release versions such as CENTOS, REDHAT, and UNIX common hair styles versions such as AIX, hp-UNIX, SOLATIS. The operating system implemented by the center does not affect the network communication between the center and the management platform.
The present invention will be described in detail below with reference to the drawings and specific embodiments, and the objects and effects of the present invention will become more apparent.

After receiving the registration message of the platform, the management platform firstly checks whether the message sent by the platform is correct or not, checks whether the identifier in the message is registered or not, informs the center of registration if the identifier in the message is registered, and otherwise, stores the relevant message by taking the identifier in the message as a main key.
S300', after the registration is successful, the center sends heartbeat to a management platform;
after the management platform persists the information of the center, the platform returns a registration success message to the center and starts to wait for a heartbeat message sent by the center.
S400', after receiving the request of the center, the management platform modifies the last heartbeat time and state of the center, and the center executes related tasks after receiving the operation in the heartbeat, wherein the operation information is added in the return of the heartbeat request;
and the management platform modifies the last heartbeat time of the center in the database into the current time after receiving the heartbeat information of the center every time, and sets the state of the center to be abnormal after not receiving the heartbeat information of the center for a long time. Meanwhile, a user can modify some configurations of the center by using a management platform page, the management platform carries operation information in the next heartbeat of the next center of the corresponding center, and the state of the center is set to be configured.
S500', the center returns the result of the related task to be executed to the management platform, and the management platform updates the state of the center.
The management platform starts corresponding service to monitor the result issued by the task, and when receiving the result message sent by the center, the management platform modifies the state of the center into 'running' and informs the user of feeling the result; when the management platform does not receive the center return result for a long time, triggering overtime, modifying the state of the center to be 'running', and informing the user of overtime.
