The invention discloses a vehicle speed detection device and method for a hazardous chemical substance transportation vehicle, and relates to the field of traffic transportation, and the method comprises the following steps: obtaining a driving speed: connecting a speed measurement device to a CAN bus of the hazardous chemical substance transportation vehicle; transmitting the acquired driving speed data to the 4G terminal; data uploading: the 4G terminal uploads the driving speed data to a background monitoring system, and the background monitoring system judges the received driving speed data according to a preset vehicle speed threshold value; data analysis: when the driving speed data exceeds a preset vehicle speed threshold value, a prompt device sends prompt information that you are overspeed to a driver so as to remind the driver to decelerate; meanwhile, the 4G terminal sends an instruction to the sensing layer device. The device is more accurate in vehicle speed detection, is not influenced by pulse signals or GPS signals, is more effective and direct in background supervision, is simple, is convenient to install, and is low in cost.

    本发明公开了一种危化品运输汽车车速检测装置及方法,涉及交通运输的领域,包括以下步骤:行驶速度获取:使用测速装置连接到危化品运输汽车的CAN总线;将获取到的行驶速度数据并传输至4G终端;数据的上传:4G终端将行驶速度数据上传至后台监控系统,后台监控系统根据预设的车速阈值,对接收到的行驶速度数据进行判断;数据的分析:当行驶速度数据超过预设的车速阈值,则通过提示装置向司机发出“您已超速”的提示信息,以提醒司机减速;同时,4G终端向感知层装置发送指令。本发明对车速检测更为精确,不受脉冲信号或GPS信号影响,后台监管更为有效直接,并且装置简单,安装方便实现成本低。
