Automatic door safety system with multiple safety modes
First Claim
1. An automatic door diagnostic system for operating a door, a switch and a motor, comprising:
- a controller for operating said motor;
a sensor, for detecting a hazard condition, wherein said sensor generates a hazard signal when said sensor detects a hazard, wherein said hazard signal is one of a first mode and a second mode, and wherein said hazard signal is transmitted to said controller wherein when the switch is activated, said controller performs a diagnostic check to determine whether at least one of said sensor, a connection between said sensor and the switch, the switch, a connection between the switch and said controller, and said controller are functioning properly and if so, said sensor generates an OK signal, and wherein if any of said sensor, said connection between said sensor and the switch, the switch, the connection between the switch and said controller, and said controller are not functioning properly, the OK signal is not generated and said controller switches to a not OK mode.

Abstract
An automatic door diagnostic system for operating a door and a door motor which detects and reacts to various hazard conditions. According to one embodiment of the present invention, a sensor is used to detect hazard conditions and communicates with a controller which operates a motor for opening and/or closing the door. The controller then operates according to various protocols to open, close, stop and/or reverse the direction of the door. Additionally, according to various alternative aspects of the present invention, the automatic door diagnostic system can be configured to perform diagnostic checks to ensure proper operation of the components of the system.

10. A method for diagnosing an automatic door system and for operating a door and a motor, comprising the steps of:
-
providing a controller for operating said motor;
sensing whether a hazard condition is present;
generating a hazard signal according to whether a hazard condition is present;
communicating said hazard signal to said controller;
controlling the motor to open or close said door according to said communicated hazard signal; and
determining whether at least one of a sensor, a connection between said sensor and a switch, said switch, a connection between said switch and a transmitter, and said transmitter are functioning properly, and wherein if any of said sensor, said connection between said sensor and said switch, said switch, said connection between said switch and said transmitter, and said transmitter are not functioning properly, said controller switches to a hazard mode. - View Dependent Claims (11, 12, 13, 14, 15, 16)
