Final project for ECE 1140: Systems & Project Engineering

ece1140's Issues

Loading the Schedule crashes the system

This is because when the train is set to automatic mode it sets the end block as the last block of the green line which is a bug that crashes the system

System crashes if driver opens doors while train is stopped in a non-station block

restructure the train controller classes

Train can not leave block 0

Have to figure out how to control when a train leaves block 0. Will possibly fix by placing train on block 1 with first nonzero power command.

All Track Controller Hardware Features

• Speed and Authority sent

• Automatically set traffic lights

• Automatically set switch positions

• Train presence and Failures

• CTC track occupancy

• Railway crossings

• PLC boolean

• Load PLC

• Manually switch

• Safety critical architecture

Reproducible Runtime Error

faulty result variable

ece1140/errors.c

Line 12 in 73f39d2

printf("result = %d", result);

Add beacon data to Track Model

• tunnel presence
• station presence
• station name
• platform side

Loading in Proper Line name

plc button on HWUI not transmitting

sending 0s when I press it so the reupload software UI is not popping up

Automatic mode dispatches all trains at once

need to sync the start time of each train to the system time so they dispatch properly

Automatic Mode crashes on second train dispatch

Somethin in the SW Track Controller code

automatic v manual

automatic is still running when i set to manual, so the switch is oscillating position

CTC mode is not properly setting

using a CTCMode* to get the mode but the mode returns no value. Crashes the system

integrate track circuit data

Segfault from TrainModel

Trying to pick up passengers in the yard

Divided stations (2 Blocks on 1 Station)

Side association for each track

CTC: Cancel dispatch if the station or timeframe is incorrect

The CTC will still dispatch a train even if the destination or time frame is incorrect.

If the destination or time frame is incorrect, the CTC should cancel the dispatch.

Train left/right doors do not respond correctly

The left and right doors do not open correctly when commanded to.

add speed controls to train controller

Signal changing at one block causes cascade to all other blocks

Semantic error

semantic error found in code

ece1140/errors.c

Line 10 in 73f39d2

a + b = c;

• fully functional UI
• set service brake until Kp and Ki are set
• add left and right door
• units uniformity
• Integrate beacon
• Integrate failures
• Add stopping at stations for 60 seconds

Friction causes train velocity to 📉

bad that velocity is severely limited by having one motor and friction, especially on heavy trains

serial port not working

track controller hardware not communicating with code

Lag on hardware UI when switching between blocks

delayed response from joystick input

Schedule loader will crash if you hit cancel

just don’t hit cancel when searching for a schedule file or the system will crash :/

make the train controller ui not look like complete garbage

it literally sucks

Implement a timer, continuously communicate with train model

Syntax error

syntax

ece1140/errors.c

Line 14 in 73f39d2

printf("numerator = %d", n);'

add vital architecture to HW Train Controller

Announcements do not update on HWTrainC UI

fix serial port delays in HW Train Controller

Train model BlockNum not initialized, giving weird values

Load schedule tab not syncing with automatic dispatch

Have to link choosing a schedule from clicking the automatic dispatch button instead
