| GSM/GPRS based Asset Information Management System: |
| |
| Description |
| |
 |
The GSM/GPRS based positional information system with integrated GPS receiver provides up-to-date location information for tracking the Tugs/ships in the port. It also allows emergency message transmission from Tugs/Ships/locomotives to Network Center. The system primarily consists of a GPS receiver integrated with a GSM Module fitted on the Tugs/ships. |
|
The positional data acquired by the GPS receiver will be transmitted by modem as GPRS packet to network center. At the network center, the data will be collected by the GPRS server, this data will be processed and stored in a database. The user can access the data through the internet by logging in to the web interface provided. MIS Reports and GIS-GPS integration are provided for viewing the messages, statistical reports for tracking the tugs on a digitized map. Network diagram is shown in figure below. |

| |
| Overview of the System and Network: |
| The system consists of three different segments. |
| |
| a) Vehicle Mount Unit (VMU) |
| b) GSM/GPRS Service provider network |
| c) Network center |
|
| |
 |
a) Vehicle Mount Unit (VMU) |
|
| |
| i) Introduction |
| |
| The vehicle mount unit mainly consists of GPS Receiver, Central processing controller, GSM modem, Power supply unit (Battery), GSM Antenna and L-Band Antenna. The positional data acquired from GPS receiver will be sent to network centre through GSM/GPRS. The central processing controller continuously monitors the GPRS link availability and automatically changes the transmission mode to SMS wherever GPRS is not available. An emergency button is provided to the unit for transmitting emergency messages to the network center. |
| |
| The unit can be configured over the air to change the important parameters like periodicity of the messages etc. The transmission of GPS data and emergency messages from the unit to the network center will be through GSM/GPRS.VMU also collects the data related to various parameters (fuel, speed etc) of the assets and forward the same to the network centre. VMU has sufficient memory to store the messages as per the requirements. VMU designed to withstand for harsh environmental conditions.VMU will also have RS-232, USB interfaces to communicate with external devices. Logic levels and type of interfaces for communicating with assets shall be finalized after discussing with the Sea Port. The block diagram of the vehicle Mount unit is shown in figure 2. |
| |
| In case of failure of GPRS, the equipment should automatically change to SMS mode and should send the data through SMS data message to the central server at the Sea Port at predefine time interval for SMS mode as set by administrator of the Sea Port. |
| |
| During GPRS and SMS Blackout, or non-availability, the data should be stored in the memory and pump the data once it reaches GPRS coverage. Store and Forward at GPRS mode only. Data collected will be pushed to central server at the Sea Port using GPRS/SMS |

b) GSM/GPRS Service provider network |
|
| |
 |
The cell segment consists of Base Stations to which the GSM modem communicates. |
|
The user segment consists of GSM modem (Transceiver), which is mounted on the Vehicles that needs to be tracked. |
|
Network Center connected to the SMS server for sending and receiving messages. |
|
| |
 |
c) Network Center |
|
| |
| The Client Network Center will have its own database server where all the data received will be stored. The MIS Reports and GIS-GPS integration modules can also be installed at the Client Network Center. When receiving data over GPRS, the data will be directly received at the Client’s Network Center by use of GPRS server. GPRS Server can then store the received data into a database. SMS server can also be installed at the Client Network Center. The SMS server will be used for receiving SMS data over GSM network wherever GPRS coverage is not available. SMS server can also be used to send the messages to the VMU for configuration. |
| |
| The network center consists of the following software modules: |
| |
i. GPRS Server
ii. SMS Server
iii. MIS Reports Module
iv. GIS-GPS Integration Module |
| |
| i) GPRS Server: The GPRS server software runs at the Network Center receives the data sent by a VMU of various assets. The data will be processed and stored into a database. Administrative screens are provided to manage VMUs, Database, Hardware and Log. It provides different system administration reports that can be viewed by the administrative user. Some of the reports are given below: |
| |
|
Messages received for a period: List and count of text messages received for a specified date and time. This report may contain messages of all the Assets or it can be filtered for a particular Asset. |
|
GPS Messages received for a period: List and count of GPS messages received for a specified date and time. This report may contain messages of all the Assets or it can be filtered for a particular Asset. |
|
System Log: The system generated event logs for a specified date and time. It can further be consolidated or a break up of event wise or Asset wise. |
|
| |
| ii) SMS Server: SMS server will be installed at Client Network Center which provides SMS gateway facility for sending and receiving SMS messages between VMU and the Network Center. This facility will be utilized whenever GPRS connectivity is not available and also to update the configuration of the VMUs through SMS. A modem will be provided at Network Center to interface with SMS server. |
| |
| iii) MIS Reports Module: A Graphical user interface (GUI) is provided for viewing the various reports based on the data received from various assets. The reports are generated according to the user query. Additionally customization will be done as per Sea Port Port requirements after the award of contract. Some of the details are as follows; |
