Problems solved by technology

[0003] With the diversification of car models of automobile enterprises, the development cycle of new models is compressed, and the cycle of introducing production lines is short. The existing emission detection and testing methods are mostly dual-idle exhaust gas detection schemes. By controlling the speed to the range value required by the national standard, it no longer meets the new requirements. National standard, the new national standard implements the industry without mature experience, and urgently needs pioneering introduction

Embodiment 1

[0032] Such as figure 1 As shown, the present embodiment provides a test platform for gasoline vehicle pollutant emission detection, a packet monitoring system, a data transmission system and an equipment detection system. The monitoring system uses Ethernet to perform data interaction and transmits data to Data transmission system, the data transmission system uses Ethernet to transmit detection data and model data, and transmits the data to the equipment detection system, which detects pollutant discharge and returns the data to the data transmission system;

[0033] The equipment detection system includes a chassis dynamometer, a code scanning gun, an industrial computer, a gas analyzer, an OBD diagnostic instrument, a weather station, and a PLC; the vehicle to be detected drives into the chassis dynamometer, and the code scanning gun is used to Obtain the VIN number of the vehicle to be tested and transmit it to the industrial computer, and then the industrial computer con...

Embodiment 2

[0045] Such as figure 2 As shown, the present embodiment provides a test method for a test platform for gasoline vehicle pollutant emission detection, and the specific steps are as follows:

[0046] Step 1: The inspector drives the vehicle onto the chassis dynamometer, stops the vehicle, puts it in P gear, and turns on the handbrake;

[0047] Step 2: The inspector obtains the VIN number of the inspection vehicle through the code scanning gun, and transmits it to the industrial computer. The inspection platform obtains the vehicle sequence and corresponding configuration from the upstream integrated server, transmits it to the equipment routing, and sends the inspection task to the industrial computer;

[0048] Step 3: The lifter of the chassis dynamometer is lowered, the inspector straightens the body, turns on the parking brake, prepares for the environment, connects the gas analyzer to the vehicle exhaust system according to the equipment prompts, and releases the vehicle E...

Abstract

The invention discloses a test platform for gasoline vehicle pollutant emission detection and a test method thereof, and belongs to the technical field of vehicle emission detection. The test platformcomprises a monitoring system, a data transmission system and an equipment detection system; the monitoring system uses the Ethernet to perform data interaction, data are transmitted to the data transmission system, the data transmission system transmits detection data and vehicle model data by using the Ethernet and transmits the data to the equipment detection system, and the equipment detection system detects pollutant emission and transmits the data back to the data transmission system. According to the invention, the test platform distinguishes the vehicle model by receiving the vehiclemodel data of an integrated server, automatically determines the detection standard type, guides a detector to carry out pollutant detection, and returns the detection data to the integrated server; and the detection data are reserved in a local data server and are synchronously uploaded to a cloud integrated server, so that data tracing of all detection vehicles is realized.

Description

technical field [0001] The invention belongs to the technical field of automobile emission detection, and in particular relates to a test platform and a test method for detecting pollutant emission of gasoline vehicles. Background technique [0002] In order to implement the "Environmental Protection Law of the People's Republic of China", control vehicle pollutant emissions, and improve ambient air quality, the Ministry of Ecology and Environmental Protection has formulated a new GB 18285. Automobile manufacturers need to conduct emission testing on new vehicles after they roll off the production line. [0003] With the diversification of car models of automobile enterprises, the development cycle of new models is compressed, and the cycle of introducing production lines is short. The existing emission detection and testing methods are mostly dual-idle exhaust gas detection schemes. By controlling the speed to the range value required by the national standard, it no longer m...
