5.1 | 1 | == Trains == |
| |
4.1 | 2 | |
| |
5.1 | 3 | Each train has a trainnumber. The trainnumber is for prioritization, when multiple trains compete for the same track. Lower numbers mean higher priorities, e.g. train 0 has the highest priority. Priorities can't be changed dynamicly. |
| 4 | Each train has one home-track at each station. | ||
| 5 | |||
| 6 | === Train numbering === | ||
| 7 | |||
| |
4.1 | 8 | Variable **trainNum** is used to identify trains. |
| 9 | |||
| 10 | The assignment of numbers to trains is chosen as followed | ||

3.1 | 73 | == Logging == |
| 74 | |||
| 75 | Variable **debug** indicates verbose logging. | ||
| 76 | |||
| 77 | Prefix of all log messages must be :** [trainnum][ST-ST]** | ||
| 78 | |||
| 79 | Use **println** function to produce textual output. Do not use printf or other io functions, because output may not be flushed correctly. | ||
| |
5.1 | 80 | |
| 81 | == Tracks == | ||
| 82 | |||
| 83 | Stopping on tracks without contacts is permitted. Therefore they must be reserved and used with an adjacent track. | ||
| 84 | Each station has one drive-through track for each possible direction: | ||

11.1 | 114 | === Station-to-Station === |
| 115 | |||
| |
12.1 | 116 | Fuctions **void railArrival(int train, int station)** and **int railDeparture(int train)** should be used at the end of every Station-to-Station-Controller. |
| |
11.1 | 117 | |
| |
12.1 | 118 | At the end of every Station-to-Station-Controller the trains should stand in one station, because every controller starts with the train in standstill. |
| |
11.1 | 119 | |
| 120 | === TrainController === | ||
| 121 | |||
| 122 | Train-Schedules should be modelled by putting together the Station-to-Station-Controllers for every train in individual regions. | ||
| 123 | |||
| 124 | === Speed: === | ||
| 125 | |||
| 126 | * SLOW: for the stations | ||
| |
13.1 | 127 | * CAUTION: for slowdown (and optional points) |
| |
11.1 | 128 | * NORMAL: for the other tracks |
| 129 | |||
| |
5.1 | 130 | == Codestyle == |
| 131 | |||
| 132 | Use entry-/exit-actions instead of actions on transitions, if possible. | ||
| |
7.1 | 133 | If using hostcode, only use functions delivered by our own C-Interface and not the Höhrmann-API. |
| |
5.1 | 134 | |
| 135 | == Mutual Exclusion == | ||
| 136 | |||
| |
8.1 | 137 | bool <track>_req[<trainAmount>] contains the requests for each track and train. Before the availability of arrays, we used bool <train>_<track>_req. |
| |
5.1 | 138 | int <track>_perm contains the trainnumber of the train, who is allowed to drive on <track>. |
| |
9.1 | 139 | |
| |
14.1 | 140 | = C Controller = |
| |
9.1 | 141 | |
| |
14.1 | 142 | The C controller wraps the basic railway interface and creates an correct environment to run the generated controller. |
| 143 | |||
| 144 | == Make Script == | ||
| 145 | |||
| 146 | A make script written in Python is located in rail-repo: code/make.py | ||
| 147 | |||
| 148 | This script will compiel the whole controller for simulation or real railway and optionally executes it.// | ||
| 149 | // | ||
| 150 | |||
| 151 | Calling**// python// //make.py//** without further command-line arguments will print a help message with all available command line options. | ||
| 152 | |||
| 153 | Make Script Features: | ||
| 154 | |||
| 155 | * Header-file will be included automatically | ||
| 156 | |||
| 157 | Results are located in //rail-repo: code/build/// | ||
| 158 | |||
| 159 | == Railway Interface == | ||
| 160 | |||
| 161 | Provided functions are defined in// rail-repo: code/hostcode/controller.h// | ||
| 162 | |||
| 163 | == Interaction == | ||
| 164 | |||
| 165 | === Quit, Pause and Cleanup === | ||
| 166 | |||
| |
9.1 | 167 | Quit, pause and cleanup functionality is handled in the c interface. |
| 168 | |||
| |
10.1 | 169 | **CTRL+C** (SIGINT)** **quits the controller |
| |
9.1 | 170 | |
| |
10.1 | 171 | **CTRL+\** (SIGQUIT)** **cleans up |
| |
9.1 | 172 | |
| |
10.1 | 173 | **CTRL+Z **(SIGSTP) pauses and continues |
| |
