Working status of the self-propelled aerial work platform ( SAWP ) need to be monitored at any time in order to en-sure drive and operation safety, thus computation design and redundancy design were used in electric control system of the SAWP, at the same time, the key factors including ground slope, rated load, inclination angle of the chassis, luffing angle and telescopic length of the booms were all taken into consideration. Angle sensor, weight sensor, displacement sensor and proximity sensor, etc. were both used in the SAWP in order to control drive speed, operation speed and motion range so that hazards could be controlled automatically in case of risk conditions or misoperation at work. At the same time, the operator will be warned that the adjustment should be carried out immediately. At last, the stability and reliability of electric control system based on various sensors were veri-fied by the ground test and the customer service, and the results are satisfied.%为保证自行式高空作业平台的行走和作业安全,电控系统需要时刻监控整车的使用状态.因此,对电控系统的安全设计采用运算设计和冗余设计相结合的方法,以地面坡度、承载质量、底盘状态、车体位置、臂架长度、臂架角度等因素作为判据,并使用角度传感器、称重传感器、位移传感器和接近传感器等元件作为核心检测装置,控制整车的行走速度、作业速度和作业范围.当发生危险工况或误操作时,电控系统会自动限制危害安全使用的动作发生,同时警示操作者及时调整使用状态,最大限度保证安全.最后,通过场地实验测试和客户跟踪测试,验证了使用各类传感器的电控系统的稳定性和可靠性.
