夜航探照灯车控制系统设计

设计了一种夜航探照灯车控制系统,包括主控器、数据采集/驱动板、遥控装置三部分,其中主控器用于灯车监控视频和工作参数的显示,同时接收塔台遥控装置发送的无线指令控制灯车.数据采集/驱动板包含两部分:数据采集板,用于对探照灯的工作参数进行采集,包括探照角度、工作电流和电压,且利用传感器并通过电气隔离的方法实现直流信号的高精度测量;电气驱动板,用于实现灯光和探照角度控制,采用汽车电子行业成熟稳定的控制器局域网(CAN)总线进行通信.塔台遥控装置通过2.4 GHz频段与主控器进行通信,组成星状网络控制任意一台灯车.测试表明:灯车控制系统参数测量精度保持在1％以内、通信稳定可靠、功能和性能均符合系统设计要求.

Design of control system of night air search light vehicle

A night air search light vehicle control system is designed,which includes the host controller,data acquisition/driver board,remote control device.The host controller is used to control car monitor video and display working parameters,meanwhile receive wireless instructions from the remote control device to control the lamp vehicle.Data acquisition/driver board consists of two parts,one is the data acquisition board,which is used to collect working parameters of the lamp,including lamp's angle,working current and voltage which are accomplished by means of sensor and electrical isolation measurement,the other one is electric driven board,which is used to implement light and angle control,the control system adopts the mature and stable controller area network(CAN) bus in the automotive electronics industry for communication.The tower remote control device communicates with the main controller through the 2.4 GHz frequency band,which can form the star network to control any lamp vehicle.The test shows that the parameters of the control system are kept within 1％,the communication is stable and reliable,the function and performance meet the requirements of system design.
