Determining asset location via local triangulation
View Patent ↗The present invention is a method for locating an asset in a facility. An example of an asset is a vehicle and an example of a facility is a parking facility. When the user enters the facility with the asset, the user receives a base and code from a base/code booth. The code may be stored on a removable card. The user secures the asset by entering the code. While the user is away from the facility, the present invention monitors the base for movement detected by the motion sensor. When the user returns to the facility, a locator panel displays the location of the asset. The present invention determines the location of the asset by triangulation using the locators. The user then returns to the asset, deactivates the motion sensor, returns the base and code to a base/code booth, pays for the storage services, and exits the facility.
1. A method for determining the location of an asset comprising:
removing a card from a base, the base placed in the asset and comprising a sensor;
scanning the card at a locator panel in a facility to indicate that the asset is unattended in the facility, wherein a construction material for the facility prevents a transmission of signals between floors of the facility, and each floor of the facility comprises at least three locators in communication with the locator panel, the at least three locators configured to determine, with the locator panel, a location of the base;
determining, by the sensor, whether the asset has been disturbed; and
responsive to a determination that the asset has been disturbed, dispatching a security patrol to the location of the base provided by the locator panel.
2. The method of claim 1 further comprising:
responsive to scanning the card at the locator panel, printing directions from the locator panel to the asset or displaying the location of the asset on a display screen.
3. The method of claim 1 further comprising:
determining whether a user, who has scanned the card and left the facility, has returned to the facility because the card has been re-scanned; and
responsive to determining that the user has returned to the facility, and responsive to determining that the asset has been disturbed, taking no action.
4. The method of claim 1 further comprising:
wherein the sensor is a motion sensor.
5. The method of claim 1 further comprising:
wherein the sensor is a glass breakage sensor.
6. The method of claim 1 further comprising storing a code on the card and inserting the card into the locator panel.
7. The method of claim 1 further comprising entering a code into a keypad on the locator panel.
8. The method of claim 1 wherein the asset is a vehicle.
9. The method of claim 1 wherein the facility is a parking facility.
