Public transport vehicles are the main carrier of the operation of public transport enterprises, and they are also their main fixed assets. But different from other assets, the use of public transport vehicles involves many departments, links, large amount of vehicle information, data update lags, resulting in high cost of public transport vehicle management, operation and maintenance, therefore, how to manage public transport vehicles scientifically and effectively, is the key to reducing costs and increasing efficiency of public transport enterprises and preventing the loss of assets.
At present, the vast majority of enterprises have realized vehicle information management, but only the establishment of vehicle information accounts, can not be based on vehicle data to assist management. The smart maintenance application, relying on the digital twin of the vehicle, collects, analyzes, and evaluates vehicle health, operation and other data in real time, and combines the algorithm model to build a vehicle portrait, forming a digital and intelligent management system for the whole life cycle from vehicle procurement, conversion, use, maintenance, and scrapping.
Vehicle procurement stage: formulate a vehicle renewal plan and establish a process-based procurement model
First of all, in the stage of public transport vehicle asset procurement, the existing vehicle health data of the enterprise is analyzed, and the number of vehicles expected to expire for scrap this year, the expected repair and maintenance vehicle data of the current year is obtained, and then combined with the current operation needs of each line and the future operation and development direction, the vehicle procurement and spare parts procurement plan for this year is formulated, and through the OA approval function, it is reported to the company's management department for approval (or reported to the higher transportation department for approval). After the approval, the follow-up purchase of vehicles and accessories will begin.
Vehicle consolidation stage: Establish a mechanism of one vehicle and one file and one code to achieve transparent management of vehicle assets
After the purchase of vehicles and accessories, it enters the stage of asset consolidation, that is, the use of digital intelligence technology to establish an asset ledger to achieve transparent asset management.
After the completion of the procurement of public transport vehicles, the vehicle management department shall handle the business of industrial and commercial registration, vehicle inspection and license plates;After the completion of the license, the operation department will register the vehicle information, including the vehicle brand, model information and follow-up maintenance informationThen the financial department will improve the invoices, insurance policies, tax certificates and other documents, and establish a one-vehicle one-file mechanism as a whole, so as to realize a file to view the complete information of the vehicle, and facilitate the follow-up vehicle asset inventory.
Smart Maintenance-Vehicle Management).
After the purchase of vehicle parts is completed, the asset registration is carried out by the maintenance warehouse keeper, and the number is stored by using the first-class barcode technology to establish a one-piece one-code mechanismAfter the approval is completed, the warehouse keeper will apply for the accessories to scan the code out of the warehouse, and associate it with the information of the recipient and the vehicle used, so as to establish a transparent and process-based accessories asset management system and eliminate the unclear and loss of enterprise asset management.
Smart machine maintenance - spare parts warehouse management).
Vehicle use stage: Based on the digital twin of the vehicle, the vehicle dynamic monitoring is realized
After the vehicle is reconsolidated, it will be assigned to the use line as needed. In the process of vehicle use, with the help of digital twin technology, the health status and operation status of the vehicle are monitored in real time, and then data support is provided for vehicle maintenance and operation planning.
First of all, based on the Internet of Things, big data analysis, digital twin and other technologies, real-time collection and monitoring of vehicle motor, battery, transmission, brake and other key components of the data, build a vehicle digital twin model, to achieve real-time monitoring of vehicle health status, so as to establish a vehicle health assessment, early warning mechanism, convenient to predict the safety risks of the vehicle in advance, and provide data support for the formulation of vehicle repair and maintenance plans, effectively increase the service life of the vehicle.
Smart Maintenance-Vehicle Digital Twin).
At the same time, based on the public transport big data analysis platform, the vehicle operation data is collected and monitored in real time, including vehicle revenue per 100 kilometers, passenger flow per 100 kilometers, power consumption per 100 kilometers, GPS mileage, operating duration, number of alarms per 100 kilometers, number of accidents per 100 kilometers, maintenance costs and other operational indicator data, build a vehicle operation portrait, and establish a dynamic monitoring mechanism for vehicle operation status and efficiency, so as to provide data support for vehicle deployment and operation planning, and effectively improve the efficiency of vehicle use.
Intelligent maintenance - vehicle portrait).
Vehicle maintenance stage: Establish a transparent workshop to realize the maintenance process management
Transparent workshop refers to the use of the Internet of Things, big data analysis, visual AI algorithm and other technologies to collect and analyze the whole process of vehicle maintenance data in real time, and combined with mobile phones, electronic kanban and other terminal equipment to achieve transparent management of the whole process of vehicle maintenance, greatly reduce vehicle maintenance costs, and improve vehicle maintenance efficiency.
First of all, the transparent workshop realizes the "one vehicle, one order" maintenance mechanism, which solves the problem of opaque maintenance business process. The specific process includes, the operator (such as the driver) according to the vehicle failure or maintenance plan, in the mobile phone application to initiate the repair or maintenance approval form, the team manager in the web or mobile terminal online audit, and designate the team personnel to carry out the pre-inspection, after the completion of the pre-bolt, the team manager and then dispatch, the team maintenance staff after receiving the work order to initiate the application for picking out of the warehouse, the warehouse keeper according to the process to scan the code out of the warehouse, the maintenance staff after the material to start repair, maintenance, maintenance after the completion of the quality inspection factory registration.
Smart maintenance - transparent workshop).
Secondly, the transparent workshop solves the problem of opaque and non-standard vehicle maintenance process. The platform can automatically collect and analyze all the data from the process of receiving the car to the factory, and display the data in real time on the dashboard of each terminal, such as the workshop kanban (which can be synchronized to the management application) to view all vehicles, pending repair, dispatch, and repair status, as well as view the on-site construction status of all repairers, so as to facilitate enterprise leaders to grasp the vehicle maintenance situation in real timeThe team kanban can be classified according to the type of work (machine repair, painting, sheet metal) team classification to display the team in repair, abnormal state, in order to facilitate the adjustment of the maintenance plan;The operation dashboard allows operators to view the waiting time, repair time, estimated completion time, etc., to facilitate the adjustment of the operation plan.
Vehicle Retirement Stage: Establish an orderly retirement plan to maximize asset utilization
The service life of public transport vehicles is usually ten years, and they need to be scrapped and disposed of after the expiration of the operation period, so public transport enterprises need to establish an orderly vehicle scrapping plan according to the actual use of the vehicle and combined with the actual operation needs, and complete the scrapping approval process of the vehicle through the operation department. After the process is passed, the vehicle disposal department completes the process of vehicle dismantling or transfer according to the actual needs. Vehicle dismantling refers to the dismantling and sorting of the available parts of the scrapped vehicle as spare parts for the same operating vehicle, thereby reducing the cost of vehicle maintenanceThe transfer refers to the transfer of obsolete vehicles in good condition to maximize the utilization of vehicle assets. Finally, the operation department will then hand over the supporting documents and related income of the vehicle to the finance department for account verification.
