British engineers have recently developed an in-vehicle intelligent system that can point out the parts that need to be repaired for repairers. Through the electronic tracker installed in the engine and other places, the system can report the status of various components within a few seconds.
According to British media reports, this system was designed by researchers at Cambridge University’s School of Manufacturing. After being equipped with the necessary software, it can not only speed up maintenance, but can even identify which parts can be recycled when the vehicle is scrapped. After collecting and studying the information from many vehicles, it is more conducive to find out which parts of the vehicle need to be redesigned.
According to the engineer, each radio frequency identifier (RFID) has its own number and can be installed on different parts of the vehicle. To check whether the vehicle needs maintenance, just let the vehicle pass a 1 square meter maintenance board at low speed, on which is fixed an UHF reader and 4 antennas. When the car passes this maintenance board, the reader will transmit the ID number from the electronic tracker to a computer, and compare the obtained information with the information in the computer database. For example, some information will display the production date and manufacturer of each component, so the maintenance personnel can click the mouse to determine whether these components need to be tested for wear.
Professor Duncan McFarlane from the Cambridge University School of Manufacturing said: “Finally, the driver can drive through a sensor with the same function and enter the repair shop. This sensor will immediately inform the driver and maintenance personnel which parts need to be replaced and which parts are still available. You can run thousands more miles.”
“However, in addition to these benefits, this intelligent system has some potential benefits. For example, when the vehicle is scrapped, the radio frequency identification tracker can be used to check which parts can still be used. The system can allow car manufacturers Know whether certain components can be recycled or reused, or whether they can be garbage disposed of. It can also point out which components need to be improved in order to obtain a longer service life.” McFarlane said.
This research is part of an international project funded by the European Union, which is called Promise for short. McFarlane added: “The Promise system also has broader potential. It allows us to track and update the information of each product after it is delivered to the customer for use and until the car is scrapped. It can timely monitor various products and components. Parts are even airport baggage and boarding passes for tracking and marking.”
Researchers said that the concept of radio frequency identification is very simple, but it contains great significance. Put a radio frequency identification tracker (a microchip with an antenna) on a product, such as a beverage can, T-shirt or axle, and the computer can “see” and recognize the product. Installing a tracker on every beverage can, every T-shirt, every axle and other commodities may bring about major reforms in industrial and commercial operations. For example, it can automatically carry out inventory counts, eliminate loss or misdelivery during transportation, and verify reliable information such as how many raw materials are in the supply chain and how many products are on the shelves.
