Vehicle state management method based on memory database

Abstract

The invention provides a novel vehicle state management method based on a memory database, comprising the steps of: mapping a system memory into a virtual disc in a system by using a virtual memory disc technology, establishing a vehicle state database under a database storage path, transplanting the vehicle state database to the virtual memory disc, and establishing a vehicle state data table and a storage process according to the actual service requirements in a GPS management system so as to maintain vehicle state data in the GPS management system, wherein complicated logic relations can be realized with a storage process algorithm, without converting the complicated logic relations into relation of key and value in one-to-one correspondence. By use of the vehicle state management method based on the memory database, million orders of magnitude vehicle state management requirements in the GPS management system can be satisfied.

Description

technical field [0001] The invention relates to the field of combination of memory hard disk technology and relational database, in particular to a vehicle state management method based on memory database. Background technique [0002] Since each vehicle station basically actively reports location information at a frequency of one minute (some even only 10 seconds or 30 seconds), a vehicle has to process more than 1,000 pieces of data a day, and each piece of GPS location information has to be sent to Authorized operators who are currently online. Therefore, an operator can issue commands such as monitoring and dispatching to which vehicles have the authority, and at the same time, can receive the data reported by which vehicles; in turn, how to send the data reported by a vehicle to the current online operator who has the authority to him Operators, these are the things to be dealt with in vehicle status management. It is necessary to manage and maintain the offline statu...

Problems solved by technology

[0013] Aiming at the deficiencies in the existing technology, the problem that the vehicle state data cannot be efficiently managed, the present invention provides a new type of vehicle state management method based on the memory database, through the virtual memory hard disk technology, the system memory is mapped to the Virtual hard disk, create a vehicle state database under the database storage path, and transplant the vehicle state database to the memory virtual hard disk, create a vehicle state data table and create a stored procedure according to the actual business requirements in the GPS management system, for maintaining GPS management For the vehicle status data in the system, the complex logical relationship can be realized through the stored procedure algorithm, instead of converting the complex logical relationship into a one-to-one corresponding key and value relationship
