摘要
提出一种多网络远程控制方法,以平行四杆结构桁架为载台,基于STM32F407芯片设计步进电机驱动电路和反馈信号采集电路。通过4G网络、W5200网络模块、One NET平台组网实现专家端口和数据中心交互控制网络相机精准定位的功能。根据实时性和精准性设计网络控制方案,并提出相机定位公式。为使水平移动误差控制在5%内,综合考虑灵敏度、稳定性、移动误差,设定电机速度为2.0 cm/s。调整参数改善网络通信并统计流量消耗,最终设定系统异常重启时长为30 s,W5200网络通信定时参数为5 s,W5200网络异常重启时长为10 s,每小时消耗流量3~4 MB。
A multi-network remote control method is proposed. With the parallel four-bar structure truss as the platform,the stepper motor drive circuit and feedback signal acquisition circuit are designed based on the STM32 F407 chip. The accurate positioning function of the network camera interactively controlled by the expert port and data center is realized by means of the networking of 4 G network,W5200 network module,and One NET platform. Network control scheme is designed according to the real-time and precision performances,and the camera positioning formula is put forward. To control the horizontal movement error within 5%,the motor speed is set to 2.0 cm/s,comprehensively considering the sensitivity,stability and movement error.Network communications is improved by adjusting parameters,and traffic consumption statistics is obtained. The abnormal restart time duration of the system is set to 30 s,the timing parameter of W5200 network communications is set to 5 s,and the abnormal restart time duration of W5200 network is set to 10 s,with 3~4 MB traffic consumed per hour.
