Systems and methods for a door monitoring system for braking a door operated by a door system

A method for operating a door braking system, the method comprising:

• determining, by a position sensor for a door, a position of the door;
• determining, based on an output of the position sensor, a speed of the door;
• determining, based on the output of the position sensor and the determined speed of the door, an anticipated position of the door at a future period;
• determining, based on the anticipated position, an anticipated speed;
• and
• determining, based on the anticipated speed, when the anticipated speed exceeds an allowable speed and engage a relay configured to disconnect a drive circuit of the door braking system controlling the door and connect at least one braking resistor to a motor controlling the door to slow the door.

A braking system for a door system operatively coupled to a door and configured to close the door, the braking system comprising:

• a position filter configured to generate a position signal, wherein the position signal is received from a position sensor for the door;
• a speed filter, the speed filter configured to generate a speed signal from the position signal;
• an anticipation circuit, wherein the anticipation circuit is configured to determine an anticipated position of the door at a future period, and wherein the anticipated position is based on the position signal and the speed signal;
• wherein the braking system is configured to:
• determine an anticipated speed based on the anticipated position;
• and
• determine when the anticipated speed exceeds an allowable speed and in response engage a relay to disconnect a drive circuit of the door system controlling the door and connect at least one braking resistor to a motor controlling the door to slow the door.
