Intelligent integrated locking devices and systems
An intelligent lock, overlock, and lock system can be electrically controlled to open and close one or more locks. The lock, lock system, and method may function on a frequency selected to avoid cross talk, which permits numerous locks to function simultaneously on the same central system with little interruption or delay. A lock may be used as an overlock for an existing lock or be a primary lock and may include a pivoting engagement structure that engages a locking mechanism to provide added strength.
1. A locking system comprising:
(a) an overlock that includes an overlock locking mechanism configured to be connected to a primary locking mechanism by an engagement structure, wherein the overlock locking mechanism and engagement structure are moveable between (i) a first, open position in which the primary locking mechanism can move to a first, open position, and (ii) a second, locked position in which the engagement structure prevents the primary locking mechanism from moving from a second, locked position to its first, open position;
(b) an electric motor that moves the overlock locking mechanism and the engagement structure between the first, open position and the second, locked position; and
(c) wherein the engagement structure has an end that includes an engagement angled tab and the primary locking structure has an arm with an end that comprises a primary angled tab, and the engagement angled tab and the primary angled tab are in contact when the overlock locking mechanism and engagement structure are in the second position.
2. The locking system of claim 1 that further comprises a primary lock that includes the primary locking mechanism moveable between the first, open position and the second, locked position.
3. The locking system of claim 1 , wherein the overlock includes a housing and the electric motor is positioned at least partially in the housing.
4. The locking system of claim 2 , wherein the primary locking mechanism is a sliding bar and the overlock locking mechanism is a sliding bar.
5. The locking system of claim 1 , wherein the engagement structure is biased to its first position or to its second position by a spring.
6. The locking system of claim 1 , wherein the overlock further includes one or more RF radio units.
7. The locking system of claim 6 , wherein the overlock includes a plurality of RF radio units and at least one of the plurality of RF radio units operates at a lower frequency than the other of the plurality of RF radio units.
8. The locking system of claim 7 , wherein the at least one RF radio unit operating at a lower frequency operates at 900 MHz.
9. The locking system of claim 7 , wherein the at least one of the plurality of RF radio units operating at a lower frequency is configured to carry larger packets of data than the other of the plurality of RF radio units.
10. The locking system of claim 6 , wherein the overlock includes a plurality of RF radio units and at least one of the plurality of RF radio units is configured to operate at a higher frequency than the other of the plurality of RF radio units.
11. The locking system of claim 10 , wherein the RF radio unit configured to operate at a higher frequency operates at 2.4 GHz.
12. The locking system of claim 6 , wherein at least one of the one or more RF radio units has a guaranteed packet delivery structure.
13. The locking system of claim 1 , wherein the overlock communicates with one or more of: (a) a temperature sensor; (b) a water sensor; (c) a chemical sensor; (d) an environmental sensor; (e) a pressure sensor; and (f) a proximity sensor.
14. The locking system of claim 13 , wherein at least one of the one or more sensors are positioned on or in the overlock.
15. The locking system of claim 6 , wherein the overlock includes at least one RF radio unit operating at 2.4 GHz and at least one radio unit operating at 900 MHz.
16. The locking system of claim 1 , wherein the engagement structure has an opening configured to receive a dowel pin.
17. The locking system of claim 1 that further includes a backhaul unit to interface with the overlock or with a central controller.
18. The locking system of claim 1 , wherein the electric motor biases the overlock locking mechanism and engagement structure towards the second position when the overlock locking mechanism and engagement structure are in the second position.
19. The locking system of claim 1 that further includes a hasp combiner positioned over the engagement angled tab and the primary angled tab.
