Introduction to the application case of EVOC IPC in the field of automotive testing: In fact, automotive testing is actually a computer network testing system established by a system integrator to test various performance targets of the car, so as to identify whether the car meets the application standards. Therefore, the focus of automobile inspection is mainly the computer network inspection system. If we want to find out how the industrial computer is used in the automobile inspection industry, we have to inquire about the computer network inspection system.
1. The composition of the computer network detection system
The computer networking detection system consists of an industrial computer, a web hub (or switch), a web adapter, and a communication interface.
The Layout of Two Computer Networking Detection System
The computer networking detection system takes the detection line server as the center to form the detection station local area network to complete the sharing of resources within the line, and at the same time, it is comprehensively connected with the supervisor and related party transactions to form a wide area network to realize the sharing of information and the supervision of functions. The most commonly used web page layout is a star topology, and the web control system mostly adopts Windows 2000 Server, while in the database field, large-scale relational databases such as Oracle and Microsoft SQL Server 2000 are more common.
3. The effect of computer networking detection system
That is, according to the relevant provisions of GB7258-2004, GA468-2004, etc., use the industrial computer to connect with the weighing, braking, speed, exhaust gas, smoke, lighting, sound level and other inspection buildings on the inspection line, and connect each station. The building's light signal is generated by treatment and collection into a digital light signal, and is automatically transmitted to the host for storage. Based on the test results, a complete test report is generated, and data query analysis and statistical functions can be provided, so as to realize the automatic detection of flexible vehicle safety. Management and information sharing with supervisors and related party transactions.
The individual effects are described below:
(1) Login subsystem
The login function is the first step of the computer network detection system. It is important to complete the information registration of the inspected vehicle and provide the necessary parameters for the detection.
(2) External search query comparison effect
The external inspection station mainly conducts surface inspection of the vehicle under inspection. According to the requirements of GA468-2004, the surface and chassis dynamic and static items of the vehicle are inspected one by one, and the surface inspection results are stored in the computer.
(3) On-line adjustment effect
After the vehicle registration is completed, the online adjustment function will adjust the vehicles that have been registered and have undergone external inspection, and complete the inspection of the subject to be inspected.
(4) Function of name and visual measurement and control
The measurement and control software on the workstation machine is the core unit of the inspection line experiment, and has a thorough link function. The main function is to realize the measurement and control functions of the detection process from the identification of input and output switches, the control of machine behavior, the treatment of the lights after the output of the controlled building sensor lights, and the data collection. It is required to test and control the speedometer, exhaust gas, smoke level, headlights, horn sound level, sideslip, axle load, braking, chassis and other items of the flexible car, guide the driver to help the driving, and test the detection The consequences are identified in a timely manner.
(5) Main control function
The main control function is usually completed by the main control industrial computer that doubles as the detection line server, and usually high-performance industrial computers are used. The main control function is mainly responsible for the overall control and adjustment of vehicle inspection, data synthesis and storage, and usually the inspection report is in the main control module. held in print.
(6) Data management
The main point of data management is to conduct cross-examination statistics on test data and complete the construction of related systems.
(7) Convenient and naive calibration function
The computer networked detection system should have convenient and accurate measurement and detection functions. Each sub-system can be calibrated by itself. The calibration method mainly provides the calibration interface of the measured values of each controlled building, and displays the zero point of each simulated input channel of the controlled building on the interface. Output, A/D value and calibration value, provide zero and reset control.
(8) Obstructing self-diagnosis and analysis reminder function
The computer networking detection system should be able to discover its own obstacles, analyze and remind the parts where the obstacles occur, and help users solve the obstacles. That is to say, when the system is running, it will automatically diagnose and remind the smart card, photoelectric switch, sensors or other obstacles to ensure the normal operation of the detection system:
(9) Monitoring efficacy
The monitoring function is mainly used to monitor the actual working environment of each station of the detection line and the detection status and location of the online vehicle, so that the owner or management function in the rest room can comprehensively investigate and inquire about the scene environment, so as to improve the transparency and performance of the detection. fair and just" principle.
(10) Recording effect of road test
For vehicles that cannot be tested online or whose test results are controversial, after the road test method is used to test, it is necessary to record the result information such as brake isolation, MFDD, adjustment time, brake stability, road test inspector into the computer and store it in the database.
After inquiring about the function of the computer network detection system, we know that each station system is responsible for completing the collection, transmission of data, and collection, processing, control and storage on the main control machine. To do this, it is necessary for each station and the main control machine to have independent computing and processing capabilities. Therefore, the place where EVOC IPC is used is each station, main control machine, intermediate server and other places as shown in the figure above. The construction is generally our 810/7271/6113LP4/1713/2.4G/80G/256M/SONY optical drive and so on.
