Method for monitoring on-line state of vehicle-mounted global positioning system (GPS) terminal in real time

Abstract

The invention provides a method for monitoring the on-line state of a vehicle-mounted global positioning system (GPS) terminal in real time and relates to a method for processing mobile terminal data in a GPS monitoring system. The method for monitoring the on-line state of the vehicle-mounted GPS terminal in real time comprises the following steps that: a communication relationship and a data sheet are established in the system; a vehicle-mounted GPS terminal logs in and is written into a database and a network management server; the vehicle-mounted GPS terminal is off line and is written into the database and the network management server; and an operating terminal receives and displays the on-line state of each vehicle-mounted GPS terminal provided by the network management server. By the method, the problems of interference to the database and data distortion because the operating terminal inquires the database regularly to display the on-line state of the vehicle-mounted GPS terminal timely are solved.

Description

technical field [0001] The invention relates to a method for processing mobile terminal data in a GPS monitoring system. Background technique [0002] Existing GPS monitoring systems such as figure 1 As shown: a monitoring center 1 communicates wirelessly with multiple vehicle-mounted GPS terminals 2. On the one hand, it monitors the running conditions of these vehicle-mounted GPS terminals 2 according to the data uploaded by each vehicle-mounted GPS terminal 2; Control instructions and provide service information. The monitoring center 1 is provided with a GPRS front-end processor 11 , a service server 12 , a database 13 , a network management server 14 and a plurality of operating terminals 15 . The GPRS front-end processor 11 communicates wirelessly with each vehicle-mounted GPS terminal 2 through a mobile communication network. In the monitoring center 1: the service server 12 is connected with the GPRS front-end processor 11 to realize two-way information exchange. ...

However, since the business server will perform a large number of data access operations on the database; if the time interval for each operation terminal to query the database is short, such as 1 minute, then each operation terminal will query the database too frequently, which will affect the normal operation of the database; If the time interval for each operation terminal to query the database is long, such as 10 minutes, the current online status data of each vehicle-mounted GPS terminal in the vehicle monitoring table of each operation terminal will be distorted, which will affect the control of the operator.
