specific Embodiment 1

[0019] Single equipment data self-evaluation dust load weight method, dust load monitoring equipment is installed on social vehicles, atmospheric monitoring equipment is installed on the top of social vehicles, monitoring indicators are PM2.5, PM10, PM100, dust load monitoring equipment is installed on the bottom of social vehicles , the monitoring index is PM100; the data of the two monitoring devices are uploaded synchronously, and the upload frequency can be adjusted; hereinafter, the PM100 data monitored by the atmospheric monitoring device is referred to as the atmospheric value, and the PM100 data monitored by the dust load monitoring device is referred to as the dust load value.

[0020] The data comparison computing system analyzes and obtains the data curve, and the x-axis is time in seconds, and the y-axis is PM100 data in micrograms / cubic meter; the present embodiment takes 5 minutes as a data calculation cycle, and the data upload frequency in the cycle is 1s. There...

specific Embodiment 2

[0024] Data calibration of multiple social vehicle equipment, a method for remote calibration of the drift data of the dust load monitoring equipment without dismantling the equipment;

[0025] Taking dust load monitoring equipment installed on ten vehicles in a certain city as an example, according to the road density distribution of ten vehicles within a week, set up a standard equipment on the road with the highest frequency of vehicles passing by, and set the sampling position of this point on the standard road surface. The sampling area of ​​the equipment is used to measure the dust load on the road surface. The sampling time frequency of the equipment is once an hour. For example, the dust load data on the road surface measured at 16:00 is recorded as T 1 , then define T 1 It is the standard value of dust load during 16:00-17:00.

[0026] From 16:00 to 17:00, the dust load data of social vehicles passing through the standard equipment sampling area 50m before and after ...

Abstract

A method for monitoring the road dust accumulation load by using a social vehicle is characterized in that n pieces of equipment are arranged, a dust load monitoring sensor is carried on the social vehicle, and the social vehicle is used for monitoring the road dust accumulation load on the premise that the equipment is not disassembled and assembled. The randomness of the social vehicle is utilized, so that the measured road is less interfered by human factors, and more effective data can be obtained; the social vehicle is an existing shared resource, equipment is carried to the shared resources to monitor dust accumulation load, and the use cost of the monitored vehicles can be effectively reduced; and data self-calibration of a single device and data fixed-point calibration of multipledevices enable monitoring data of a bicycle to be more objective, the multiple devices are more consistent, data errors are reduced, the maintenance period is shortened, and the data accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a method for monitoring road dust loads using social vehicles. Background technique [0002] The invention patent "measuring device and method for road area dust load" (authorized announcement number: CN 104237094 A) discloses a road area dust load measuring system, which includes: a test vehicle, a particle concentration measuring device, a flow rate measuring device, a gas The conveying device and the data processing system measure the vehicle speed V and the particle concentration difference C, and then indirectly calculate the dust load concentration SL according to the correlation function relationship SL=f(C,V). Compared with the manual sampling method recommended in the "Technical Specifications for Prevention and Control of Urban Flying Dust Pollution" (HJ / T393-2007), this method is safe, has high measurement efficiency, and requires less labor. The syst...
