After the patrol operation is finished, the operation and maintenance personnel can upload the equipment defect information and the patrol report to the PMS through the handheld mobile operation terminal and transmit the equipment defect information and the patrol report to the intranet PC through the switch.
The SSO single sign-on system adopts the dual-computer hot standby and cluster technology, and the technologies ensure that the SSO server does not influence the data processing of the service system and can adapt to normal data transmission under any flow pressure. In the aspect of safety, the SSO single sign-on system adopts a special kernel and carries a safe firewall module, so that the safety and the stability of the single sign-on system are ensured.
The SSO single sign-on system does not modify the application system and adopts a bypass payroll mode. Therefore, when the single sign-on system fails, the normal operation of the original service system is not influenced except that the single sign-on function cannot be used, and the high fault tolerance function of the system is ensured. This is an important difference from the solution of modifying an application to implement a single sign-on function. By adopting the method for modifying the application program, once the single sign-on system has problems, the whole service system is influenced and may not work normally.
After the application of the SSO single sign-on system is deployed, when an enterprise user accesses and uses an original business system, the use mode of the application is not changed, which mainly means that the SSO server uses a transparent forwarding technology, that is, the use of the single sign-on system is transparent to the user.
Where the changes seen by the user are as follows:
after logging in the SSO server once, accessing any service system without identity authentication;
enterprise users need to maintain their username/password lists on the SSO server. Each user maintains its own list, and administrators cannot intervene nor need to intervene.
And a system administrator manages the single sign-on system through the management console. The SSO single sign-on system carries a graphical management console based on a Web interface and manages the single sign-on system through the Web interface. The SSO does not need to configure and modify other service systems, thereby maximally reducing the coordination work between the SSO and each service system management department and ensuring the smooth deployment of projects.
Each service system requiring single sign-on needs to be configured in the SSO single sign-on system, and the main configuration contents include:
1) configuring related information such as a network address, a subnet mask and the like;
2) a business system name;
3) a service system IP;
4) a port opened by a service system;
5) managing a user;
6) and (4) user authorization.
After the configuration is completed, the user can use single sign-on.
Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and other modifications or equivalent substitutions made by the technical solutions of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
