具有语音控制功能的举高类消防车控制系统设计

Design of control system of aerial fire fighting vehicle with voice control function

举高类消防车控制系统复杂,整车操作需要多名操作人员在多个操作位置配合完成,且对操作人员技术水平的要求较高。为此,提出了一种具有语音控制功能的举高类消防车控制系统。在举高类消防车原有控制系统的基础上,增加了自动控制功能、语音控制功能和语音播报功能,以代替常规的手柄及按钮操作方式。其中,语音控制功能即通过语音控制模块识别操作人员的特定语音指令,并通过CAN(controller area network,控制器局域网)总线发送到PLC(programmable logic controller,可编程逻辑控制器),而后PLC根据语音指令和消防车状态自动控制消防车动作。当消防车出现状态变化或发生故障时,PLC将语音指令发送至语音播报模块,语音播报模块基于预存的语音信息进行语音播放,以便操作人员接收重要信息。试验结果表明,所设计的举高类消防车控制系统具有可行性,可有效降低操作难度和提高操作效率。该新型控制系统可迅速推广至其他类型的消防车以及相关的工程机械类产品,具有较高的应用价值。

The control system of aerial fire fighting vehicles is complex,and the operation of the entire vehicle requires multiple operators to cooperate at multiple operating positions,with high requirements for the technical level of operators.Therefore,a control system of aerial fire fighting vehicle with voice control function was proposed.On the basis of the original control system of the aerial fire fighting vehicle,automatic control function,voice control function and voice broadcast function were added to replace the conventional handle and button operation mode.Among them,the voice control function was to recognize specific voice commands from operators through voice control module and sent them to the PLC(programmable logic controller)through the CAN(controller area network)bus,and then the PLC automatically controlled the action of the fire fighting vehicle based on the voice commands and the status of the fire fighting vehicle.When the status of the fire fighting vehicle changed or malfunctioned,the PLC sent voice commands to the voice broadcast module,which played the voice based on the prestored voice information for operators to receive important information.The test results showed that the designed aerial fire fighting vehicle control system was feasible,which could effectively reduce the operation difficulty and improve the operation efficiency.The new control system can be quickly extended to other types of fire fighting vehicles and related construction machinery products,which has high application value.
