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.
