摘　　要：在车载半自动发控系统中,操作人员常常通过操纵杆来控制身管的调转,从而实现对目标的跟踪瞄准控制。针对车载发控系统设计了一种基于CAN总线接口的操纵杆,该操纵杆由霍尔传感器输出两轴连续模拟量,经CAN总线接口转换为方位、高低角控制数据,还可以接收上位机的角度误差信息并通过显示屏显示。产品设计过程中充分考虑了在电磁干扰环境下工作的特点,通过在电路和软件方面采取措施,有效提高了产品的各项性能,目前已经在系统中批量应用。In the on-board semi-automatic launch and control system,the operator usually controls the turning of the barrel through the joystick to realize the tracking and aiming control of the target.A joystick based on CAN bus interface is designed for on-board launch and control system,the Hall sensor in the joystick outputs two-axis continuous analog signals,which is converted into the azimuth,high and low angle control data through the CAN bus interface,and the joystick can also receive the angle error information of the upper computer and display it through the screen.In the process of product design,the characteristics of working in the environment of electromagnetic interference are fully considered,and the performance of the product is effectively improved by taking measures in circuit and software.Currently,it has been applied in batches of system.
