In one embodiment, an electronically controlled hatch system for safe ingress, egress, hazard detection, and methods thereof are provided to reduce or eliminate hazards to personnel, including protection of people above and below a scuttle hatch, access port, skylight or elevated deck. Said hatch system reduces the risk of falls while ascending or descending a ladder through an access port. In certain embodiments, severe weather, hazard, security, and other safety information are detected and transmitted to a central control unit for processing and regulating the opening and closing of a hatch covering the access port and/or raising and lowering a safety railing system based on said information and/or user input. Said hatch system may include an actuator and guides for automatically locking/unlocking and opening/closing a hatch, an actuator and guides for automatically raising/lowering a railing system, safety monitoring detectors/apparatuses, and a centralized controller.

1. An electronically controlled hatch system for use with a hatch to limit ingress or egress through an access port, said hatch system comprising: an actuator cooperable with the hatch and having an actuator arm, the actuator arm operable to effectuate locking or unlocking the hatch and moving the hatch to at least an open position or a closed position; anda latching system, wherein the latching system is cooperable with the actuator arm to lock or unlock the hatch, the latching system comprising: a lock mechanism including a locking bolt, wherein the locking bolt is operable to be actuated to perform one of locking the lock mechanism to secure the hatch in the closed position or unlocking the lock mechanism to permit moving the hatch from the closed position to the open position;a clevis bracket operable to be coupled to an underside of the hatch;a pivot plate coupled to the clevis bracket and operable to interface with the actuator arm to effectuate locking or unlocking the lock mechanism; anda pivot rod having a first end coupled to the pivot plate and a second end coupled to the lock mechanism, the pivot rod operable to actuate the locking bolt to lock or unlock the lock mechanism;wherein movement of the actuator arm in a first direction causes limited, responsive movement of the pivot plate to effectuate movement of the pivot rod in a second direction such that the pivot rod actuates the locking bolt to unlock the lock mechanism without moving the hatch to the open position, and continued movement of the actuator arm in the first direction results in application of force to the hatch from the underside thereof to move the hatch from the closed position to the open position after the lock mechanism is unlocked. 2. The electronically controlled hatch system of claim 1, wherein movement of the actuator arm in the second direction moves the hatch from the open position to the closed position. 3. The electronically controlled hatch system of claim 2, wherein movement of the actuator arm in the second direction also causes limited, responsive movement of the pivot plate to effectuate movement of the pivot rod in the first direction such that the pivot rod actuates the locking bolt to lock said lock mechanism. 4. The electronically controlled hatch system of claim 1, wherein the latching system further comprises a pivot pin passing through a first opening in the clevis bracket and a second opening in the pivot plate, the pivot pin operable to allow the pivot plate to movably pivot thereupon. 5. The electronically controlled hatch system of claim 1, further comprising a central control unit operable to communicate with the actuator to position the hatch. 6. The electronically controlled hatch system of claim 5, further comprising a control unit operable to electronically communicate with the central control unit to control the actuator. 7. The electronically controlled hatch system of claim 1, further comprising a power source capable of at least partially powering said electronically controlled hatch system, wherein the power source is selected from the group consisting of a photovoltaic solar panel, a battery, and a fuel cell. 8. The electronically controlled hatch system of claim 1, further comprising a hatch position sensor operable to detect at least one of the open position and closed position of the hatch. 9. A latch system for locking and unlocking a hatch, the latch system comprising: a lock mechanism including a locking bolt, wherein the locking bolt is operable to be actuated to perform one of locking the lock mechanism to secure the hatch in a closed position or unlocking the lock mechanism to permit moving the hatch from the closed position to an open position;a clevis bracket operable to be coupled in direct physical contact with the hatch;a pivot plate coupled to the clevis bracket and operable to interface with an actuator arm to effectuate locking or unlocking the lock mechanism; anda pivot rod having a first end coupled to the pivot plate and a second end coupled to the lock mechanism, the pivot rod operable to actuate the locking bolt to lock or unlock the lock mechanism;wherein movement of the actuator arm in a first direction causes limited, responsive movement of the pivot plate to effectuate movement of the pivot rod in a second direction such that the pivot rod actuates the locking bolt to unlock the lock mechanism without moving the hatch to the open position, and continued movement of the actuator arm in the first direction moves the hatch from the closed position to the open position after the lock mechanism is unlocked. 10. The latch system of claim 9, wherein movement of the actuator arm in the second direction moves the hatch from the open position to the closed position. 11. The latch system of claim 10, wherein movement of the actuator arm in the second direction also causes limited, responsive movement of the pivot plate to effectuate movement of the pivot rod in the first direction such that the pivot rod actuates the locking bolt to lock said lock mechanism. 12. The latch system of claim 9, further comprising a pivot pin passing through a first opening in the clevis bracket and a second opening in the pivot plate, the pivot pin operable to allow the pivot plate to movably pivot thereupon. 13. The latch system of claim 9, further comprising an actuator cooperable with the actuator arm, the actuator operable to control movement of the actuator arm to effectuate locking or unlocking the hatch and moving the hatch to at least the open position or the closed position. 14. The latch system of claim 13, further comprising a central control unit operable to communicate with the actuator to position the hatch. 15. The latch system of claim 14, further comprising a control unit operable to electronically communicate with the central control unit to control the actuator. 16. The latch system of claim 9, further comprising a power source capable of at least partially powering at least a portion of the latch system, wherein the power source is selected from the group consisting of a photovoltaic solar panel, a battery, and a fuel cell. 17. The latch system of claim 9, further comprising a hatch position sensor operable to detect at least one of the open position and closed position of the hatch.
