摘要： 遥感数据处理地面系统的运行控制存在传感器众多、处理算法复杂、流程缺乏统一管理等问题。为此，提出结合工作流技术的通用运行控制模型，将控制逻辑和业务逻辑完全分离，简化系统结构和编程模式，作业管理系统可满足处理算法对资源的不同需求。测试结果表明，运行控制系统响应快速，系统空载时作业响应时间约为0.3 s，随着系统负载的增加，运行控制的延迟没有显著增加。

Abstract: Operation and control of remote sensing data processing system on ground faces the challenges of many sensors and complicated processing algorithms, and suffers lack of uniform workflow management. Aiming at the difficulty, this paper issues a universal model of operation and control combined with workflow technology, which completely separates business logic from control logic, simplifies the structure and programming model of the system, and satisfies various resource requirements of processing algorithms by using job management system. Experimental results show that the operation and control system achieves rapid response. The job response time is about 0.3 second at system idle time, and with the increasing of system workload, the delay of operation and control has no remarkable change.

Key words: workflow management, control model, job schedule, job management system, remote sensing data processing, data drive
