The invention relates to the technical field of VOCs pollution monitoring, and discloses a VOCs pollution sailing real-time monitoring device and a monitoring method.The VOCs pollution sailing real-time monitoring device comprises a compartment, a storage battery, a communication unit and a VOCs online monitor are arranged in the compartment, and the top of the compartment is fixedly connected with an air bellow assembly used for isolating sampling points; air inlet assemblies are arranged at the air inlet ends of the two sides of the air bellow assembly; the inflow air speed is controlled through the air inlet assembly, during sampling, air in the air bellow assembly is sucked in through the air draft assembly, the air bellow assembly is in a negative pressure state, the air bellow assembly slowly pumps outside air through the air inlet assembly, the speed of the introduced air flow is only influenced by the air draft assembly, and the sampling efficiency is improved. And meanwhile, the vehicle speed meter is arranged, the vehicle speed meter is used for monitoring the vehicle speed, when traffic jam occurs, the air extracting pump can be controlled to stop working, the situation that the air extracting pump continues to extract air when the traffic jam occurs is avoided, and the detection accuracy is further improved.

    本发明涉及VOCs污染监测技术领域,且公开了一种VOCs污染走航实时监测装置及监测方法,包括车厢的内部设有蓄电池、通信单元以及VOCs在线监测器,所述车厢的顶部固定连接有用于隔离采样点的风箱组件;所述风箱组件两侧的进风端均设有进风组件;通过进风组件控制流入的风速,在进行采样时,通过抽风组件将风箱组件内的空气抽入,使风箱组件处于负压状态,使风箱组件利用进风组件缓缓将外界空气泵入,通入的气流速度只受抽风组件的影响,使外界气流可以稳定的被泵入检测端内进行检测,同时,通过设置车速仪,车速仪对车辆速度进行监测,当堵车时,可控制抽气泵停止工作,避免抽气泵在堵车时继续抽气,进一步提升检测的准确性。
