Detailed Description

The embodiment is a digital quality detection system of whole car emission, including the pump drainage room body with set up the internal operating mode check out test set in pump drainage room, operating mode check out test set is connected with the MES system communication in the mill, MES system and the relevant department server communication of country are connected.

The working condition detection device comprises a field device upper computer, a dynamometer, a tail gas analyzer, a flowmeter, a meteorological station and an OBD diagnostic device which are arranged inside the pumping room body, wherein the dynamometer is connected with the field device upper computer through a PLC (programmable logic controller), the tail gas analyzer, the flowmeter and the meteorological station are connected with the field device upper computer through RS232 interfaces, and the OBD diagnostic device is in communication connection with the field device upper computer through Bluetooth.

In the embodiment, the upper computer of the field equipment is connected with an MES system in a factory through an Ethernet of a company, and the detection data collected by the working condition detection equipment is sent to the MES system. The MES system is connected with the report server through the company Ethernet, and the MES system is connected with the national relevant department server through the external Ethernet, and sends the detection data to the national relevant department server.

The flow of detecting the vehicle in this embodiment is as follows:

a worker drives the vehicle into the pumping room body and operates the vehicle according to the indication on the display screen in the pumping room body;

the method comprises the steps of collecting vehicle detection data through equipment such as a dynamometer, a tail gas analyzer, a meteorological station, a flowmeter and an OBD (on-board diagnostics) diagnostic instrument, transmitting the vehicle detection data to an MES (manufacturing execution system) system in a factory through an Ethernet of the company, outputting a trend report after data integration processing of the MES system for quality analysis and management, and uploading the detection data to a national environmental protection department.

Based on terminal data collectors such as sensors of working condition detection equipment, a management system (namely a data management uploading system) for detecting exhaust pollutants of a new offline vehicle is constructed by connecting a production execution management system (MES) system of a company through an Ethernet of the company and the like, and the vacancy of detection and management of the exhaust pollutants of the vehicle in the workshop Internet of things is filled. The system stores and processes the detection data of the terminal equipment through a network technology, arranges and outputs trend reports, and quality management personnel can make quality early warning in advance according to data trends, make preventive measures and improve quality control capability. Meanwhile, an uploading module is built, and the detection result data is uploaded to relevant national departments in real time according to the requirements of national standard annexes, so that the data can be quickly and effectively transmitted.

The production execution management system (MES system) records vehicle information, environmental parameters, inspection information (process data and inspection results), inspection equipment (including calibration and calibration), etc., including new vehicle off-line inspection reports, emission inspection data, OBD inspection data. The MES system is networked with the ecological environment part, and reports and sends the detection data in a specified time limit by a network service interface mode, wherein the reporting and sending data comprises vehicle information, environmental parameters, detection information, detection process data, detection results and detection equipment.
