Oscillating-balance-method-based particulate matter monitoring device and method

The invention discloses a particulate matter monitoring device and method. The device comprises a gas sampling module, a plurality of sample gas pretreatment modules, a plurality of oscillating balance sensor modules, and a control module. The gas sampling module is used for inputting collected sample gas, and carrying out the shunting of the sample gas according to difference of to-be-tested monitoring parameters. The plurality of sample gas pretreatment modules are respectively used for pretreating the sample gas of different flow paths output by the gas sampling module. Each oscillating balance sensor module comprises an independent oscillating balance sensor unit, a vibrator is arranged in each oscillating balance sensor unit, and a measuring film is arranged at the top of each vibrator and can intercept particulates. The control module is used for inputting monitoring parameters needing to be measured and automatically controlling each module to execute corresponding operation. The multi-parameter monito
