2.1 vehicle GPS monitoring subsystem
Vehicle GPS monitoring subsystem is divided into GPS software platform subsystem and GPS vehicle positioning subsystem. Among them, the GPS software platform subsystem completes the vehicle real-time data management and monitoring function, GPS vehicle intelligent terminal subsystem completes the vehicle real-time data acquisition and upload server function.
(1) vehicle terminal
The vehicle positioning terminal completes the analysis and calculation of the GPS satellite signal, calculates the position (latitude and longitude), speed, direction, time and other information of the vehicle, sends it to the GPS dispatching management center through short message or GPRS channel. The Chinese display terminal can display the dispatching information, common information, common information and so on from the GPS dispatching center.
(2) system server
The server system is composed of GIS geographic map information, vehicle monitoring, scheduling, text abnormal warning, data processing module, the basic structure is a computer network Web, through the GPRS line or DDN line and Mobile Corporation Short Message center network. It integrates computer network technology, large database, GIS geographic information system, network communication and other application technology. Complete the statistics, analysis and report of all kinds of report data. Also can gradually expand the system, began to build a smaller scale of the center, with the increase of business volume and management needs to increase the system construction, the network expansion of the program is very convenient.
(3) dispatching workstation
Workstation connection system server, through the browser under the B/S architecture, complete the daily vehicle monitoring, alarm monitoring and report management.
Technical scheme of 2.1.2 GPS software platform subsystem
The system design follows the principles of advanced technology, data security, system stability, system integration, ease of use, Yi Yusan side docking, scalability:
Technology architecture diagram:
2.1.2.2 System function list：
(1) user management
Management of login GPS software platform system user information, including the creation of user account, modify, delete, user login authentication and other functions.
(2) vehicle real-time monitoring
Real time monitoring query vehicle location and driving data, for the query choice of vehicle can be carried out by a single vehicle, packet or all vehicles, real-time location information of the vehicle and the selected data information will be reported to the center. Position information contains latitude and longitude values, and the driving state information includes time, speed, direction, information, etc..
(3) vehicle history track playback
The historical track and track replay of the vehicle are realized on the central electronic map to reproduce the driving process of the vehicle. Function as below:
4) alarm management
Record all kinds of alarm information during the use of vehicles, including overspeed alarm, fatigue alarm, in and out regional alarm, high and low voltage alarm, parking alarm, etc.. Can query the history alarm information of each vehicle.
Provide operators with different means of dealing with different types of alarms issued by the vehicle. When the vehicle alarm, the alarm target can be locked automatically, and the sound and light prompt is displayed. Meanwhile, the alarm picture is ejected, and the nature, time, geographical position, license plate number and the relevant information of the vehicle are displayed. As shown in the following picture:
(5) updating electronic map
The system uses Baidu map, the server can be connected outside the network, the map information can be updated in real time. Oilfield road map information is updated every year according to the update of the actual road, and the oil well location information is updated in real time.
Detailed design of vehicle operation and maintenance subsystem project
Vehicle operation and maintenance subsystem is a comprehensive application system which is applied to the management of fleet vehicles in each enterprise unit. The system uses modern computer network technology, in order to strengthen the enterprise vehicle management, improve vehicle utilization efficiency, improve work processes and cost saving, the full realization of the vehicle fleet maintenance personnel management automation, provides a scientific, standardized and systematic management methods to the electric transport company, improve work process cumbersome traditional manual operation and maintenance management in the process of. In order to achieve scientific and automatic vehicle scheduling and management decisions, improve operating conditions, improve production efficiency and efficiency
2.2.2 system architecture
The architecture of the system is divided into data layer, business logic layer and business presentation layer:
(1) data layer: the storage of structured data and spatial data for vehicle information.
(2) service layer: unified implementation of data management, data access, workflow and other services.
(3) application layer: in accordance with the unified security certification system and technical standards, building the system application modules
2.2.3 system requirements
The system is designed as follows:
(1) unified vehicle operation management
The establishment of a unified vehicle management platform for the company, to achieve a unified management of various vehicle resources, unified scheduling, according to the characteristics of each user and the role of different, to form a personalized application interface.
