detail description of GPS-Server
The GPS SERVER program enables the conversion of formats and management of RMS telegrams with sequence telegrams, which contain location information, for the further processing in main control panel computers with GIS (Geographical Information System).
The GPS server program can be installed on PCs with Windows NT 4.0 operating system.
Incoming RMS sequence telegrams are compared with database and evaluated according to GPS compatibility.
Reference coordinates contained in the database determine the longitude and latitude by decoding the sequence telegram and therefore the true vehicle position.
During external file collating of the database or manual changes, information is generated that mark the vehicles to be configured. These will be configured by text instructions at the next opportunity, e.g. after receiving RMS status message.
In addition, an integrated simulation environment emulates the location of vehicles with map as received from RMSKON. Some commands will also be emulated as incoming from GPS master computer and enable the configuration of the mobile equipment, regardless of database, regarding the GPS message intervals as well as the position message after exceeding a minimum distance.
Windows NT
Two vacant serial interfaces for the exchange of data with the RMSKON and the GPS master computer. (The third DGPS interface is reserved for later extensions.)
The format of RMS vehicle data is defined as follows: e.g.
| Pos. | Title | Example Value |
| 1 | Interface No. 1..4 | 1 |
| 2 | Type Code | inverted comma |
| 3 | FGA Channel No. Hi | blank character |
| 4 | FGA Channel No. Lo | 0 |
| 5 | BOS | 1 |
| 6 | State | 4 |
| 7 | Location Tens | 5 |
| 8 | Location Ones | 0 |
| 9 | Vehicle Thousands | 1 |
| 10 | Vehicle Hundreds | 2 |
| 11 | Vehicle Tens | 3 |
| 12 | Vehicle Ones | 4 |
| 13 | Status | A |
| 14 | Additional Information | E |
Only the elements 5..12
are required for the definition of the vehicle database.
A type code unlike a blank character initiates the output of the type
code format at the serial interface. This
format is also required for the cascaded concentrators in order to evaluate a
higher valued channel number (Pos. 3).
In principle, the type code is used in this software.
Monitors of both the RMS main control panel and main control panel computer with GIS enable the tracking of data flow. Incoming data is marked IN: outgoing data is marked OUT: additional information as well as fault reports are displayed.
