■High integration of the electrical inspection all-in-one machine: The entire cabinet consists of 1 Advantech industrial computer, 1 UPS, 1 OBD decoding board and 1 LCD display; the cabinet adopts Shanghai Taiyu standard 19-inch computer control cabinet (height 1600mm × width 600mm × depth 600mm), which is used to place industrial computers, OBD decoding boards, UPSs, barcode guns and label printers.

■Industrial computer is stable and reliable: Advantech IPC-610L (Core i5, 512G SSD, hard drive drawer, Gigabit network card) is used to run the master program and database; it has an impact-resistant disk drive bracket, fixed pressure strip with rubber pads, lockable front door, front accessible air filter and other industrial designs.

■Communication hardware specialty: The metal OBD cable adopts an aviation aluminum OBD head with a rubber sheath to effectively protect the vehicle, and the OBD pin definition is in line with international standards; the OBD decoding board cooperates with the industrial computer to complete the issuance of diagnostic instructions and data collection and analysis.

■Covering traditional and new energy vehicles: In addition to conventional electrical functions and fault code detection, electric vehicle motor and power battery related parameters can be detected, including total power battery voltage/total current/SOC, main relay and precharge relay suction state, maximum allowable discharge and energy feedback power, maximum/minimum allowable discharge current, maximum and minimum unit voltages and their numbers, battery maximum/minimum temperature and detection point number, battery average temperature, motor speed and real torque, motor controlManufacturer DC voltage and current, A/B phase current, motor and inverter and IGBT temperature, accelerator pedal signal, vehicle speed signal, charging connection signal, slow charging demand voltage and current, charger real-time charging voltage and current, small battery voltage, gear signal, key ON/start signal, HVAC enable and wake signal, brake pedal signal, etc.

■The result is intuitive: when the data is qualified, the background changes to eye-catching green, and when the data is not qualified, it changes to red. The default color indicates that the current data does not need to be evaluated. The program finally reads the fault code, and if the fault code is detected, it is converted to Chinese and displayed in the main interface. If there is no fault, it prompts "No fault information is detected".

■Full function: Support car fault code detection (convert to Chinese when there is a fault code and prompt NOK, no fault code prompt OK) and write the Vin code of the airbag ECU (re-read and compare after writing, if it is consistent, it prompts success).

■Centralized server management: The master server has the functions of monitoring, statistical storage, upgrading and uploading and downloading - collecting and storing the statistical analysis of the test results of all modules and generating report documents; the vehicle information can be downloaded from the MES system in advance and sent to other test modules, and the test data can also be uploaded to other networks in the factory.

■Convenient data query and analysis: The server uses the web method for data query and analysis, and any authorized computer in the factory network can browse the test data through the browser; it supports qualified/unqualified result statistics (every shift, daily, monthly, annually), custom date and time queries, order number or Vin code index queries, station/equipment test statistics, each module test result statistics, and multi-condition combination queries;The results are displayed in a list of tables and charts and can be exported to Excel; key data (VIN code, pass rate, date, fault type, etc.) can be linked for secondary retrieval and sent as an email.

■Data will not be overwritten: The test data and detailed logs of each vehicle are stored separately, and the test data of the same vehicle at different times is stored separately and not overwritten.

■Multi-functional diagnosis of the final inspection station: The final inspection station adopts a flat panel diagnostic instrument, which is used for qualification testing of vehicles with faults in the electrical inspection of the previous station or vehicles after maintenance;The diagnostic terminal has a variety of functions to perform all the diagnostic functions of the vehicle. It has a wireless communication module and a wireless connection with the main server. It uses a one-dimensional barcode such as a camera image recognition Vin and reserves a manual input of the model code function. It supports ODX, OTX, D-PDU, and DOIP diagnostic protocols and can cache more than 100 vehicle information. The detection program upgrade is pushed through the server and manually confirmed by the operator.
