【摘要】 实验室远程预约存在节点负载不均衡问题，导致预约出错次数多、预约时间差大。面对该问题，设计了基于统一身份认证的实验室远程预约机制。创新性地在统一身份认证约束条件下计算预约所需时间和预约信息平均负载，通过调整负载的方差和算术平方根值，判断分配预约任务数，达到远程预约节点负载均衡调度的目的。根据远程预约节点负载均衡调度结果，计算并更新实验综合受益总分，设计实验室远程预约机制。根据远程预约客户端与预约时间差值，判定远程预约有效性。通过计算增益误差校正控制值，校正预约时间差。测试结果表明，所设计机制预约出错次数最大仅为18次，最大时间差仅为1 min，有效降低了实验室远程预约的出错效率。更多还原

【Abstract】 The node load is imbalance in remote reservation of the laboratory, which leads to a high number of reservation errors and a large difference in reservation time. In response to this issue, a laboratory remote appointment mechanism based on unified identity authentication is designed. Innovatively, under the constraint of unified identity authentication, the required time for reservation and the average load of reservation information are calculated. By adjusting the variance and square root of the load, the number of assigned reservation tasks is determined, so as to achieve the goal of remote reservation node load balancing scheduling. On the basis of the load balancing scheduling results, the overall benefit score of the experiment is calculated and updated, and a remote reservation mechanism for the laboratory is designed. The effectiveness of remote reservation is determined based on the difference value between the remote reservation client and the reservation time. The reservation time difference is corrected by calculating gain error correction control value. The test results show that the maximum number of reservation errors of the designed mechanism is only 18, and the maximum time difference is only 1 minute, which effectively reduces the error efficiency of remote reservation of the laboratory.更多还原
