Abstract

The speed-limit-compliance system for an industrial vehicle driven by an operator includes a wireless positioning module configured for determining the location within a facility of the industrial vehicle. The system also includes a speed sensor configured for determining the speed of the industrial vehicle. A process is in communication with the speed sensor and the wireless positioning module. When executed by the processor, computer readable program code stored in a non-transitory computer readable storage medium receives from the wireless positioning module the location of the industrial vehicle. The speed of the industrial vehicle is received from the speed sensor. A speed limit and an associated restricted speed zone are stored. A speed warning is generated when the industrial vehicle exceeds the speed limit while located within the restricted speed zone.

First claim

What is claimed is:

1 . A speed-limit-compliance system for an industrial vehicle driven by an operator, comprising:
a wireless positioning module configured for determining the location within a facility of the industrial vehicle; a speed sensor configured for determining the speed of the industrial vehicle; a processor in communication with the speed sensor and the wireless positioning module; a non-transitory computer readable storage medium storing computer readable program code, wherein, when executed by the processor, the computer readable program code: receives from the wireless positioning module the location within the facility of the industrial vehicle; receives the speed of the industrial vehicle from the speed sensor; stores in the non-transitory computer readable storage medium a speed limit and an associated restricted speed zone; and generates a speed warning when the industrial vehicle exceeds the speed limit while located within the restricted speed zone.

2 . The speed-limit-compliance system of claim 1 , wherein the wireless positioning module is a WLAN-based positioning module.

3 . The speed-limit-compliance system of claim 1 , wherein the wireless positioning module is a GPS-based positioning module.

4 . The speed-limit-compliance system of claim 1 , wherein the wireless positioning module is an RFID-based positioning module.

5 . The speed-limit-compliance system of claim 1 , wherein the wireless positioning module is a UWB-based positioning module.

6 . The speed-limit-compliance system of claim 1 , wherein the wireless positioning module is an inertial-navigation-based positioning module.

7 . The speed-limit-compliance system of claim 1 , comprising:
a display screen operatively coupled to the processor; wherein the speed warning includes a visual cue displayed on the display screen.

8 . The speed-limit-compliance system of claim 1 , comprising:
a speaker operatively coupled to the processor; wherein the speed warning includes an aural cue played through the speaker.

9 . The speed-limit-compliance system of claim 1 , comprising:
a warning light operatively coupled to the processor; wherein the speed warning includes illumination of the warning light.

10 . The speed-limit-compliance system of claim 1 , comprising:
a horn operatively coupled to the processor; wherein the speed warning includes sounding the horn.

11 . The speed-limit-compliance system of claim 1 , comprising a wireless network interface for transmitting and receiving information via a communications network.

12 . The speed-limit-compliance system of claim 11 , wherein the computer readable program code, when executed by the processor, transmits a non-compliance message to a remote computer via the communications network when the operator fails to comply with the speed warning.

13 . The speed-limit-compliance system of claim 12 , wherein the non-compliance message is transmitted as an e-mail message.

14 . The speed-limit-compliance system of claim 12 , wherein the non-compliance message is transmitted as a text message.

15 . The speed-limit-compliance system of claim 12 , wherein the computer readable program code determines that the operator has not complied with a speed warning if, after the expiration of a pre-determined time period following the generation of the speed warning, (i) the industrial vehicle is located within the restricted speed zone and (ii) the industrial vehicle's speed exceeds the speed limit.

16 . The speed-limit-compliance system of claim 12 , wherein the computer readable program code determines that the operator has not complied with a speed warning if the industrial vehicle's speed exceeds the speed limit a pre-determined number of instances following the generation of the speed warning.

17 . The speed-limit-compliance system of claim 11 , wherein the computer readable program code, when executed by the processor, receives the speed limit and the associated restricted speed zone from a remote computer via the communications network.

18 . The speed-limit-compliance system of claim 17 , wherein the remote computer is configured for setting the speed limit and the associated restricted speed zone based upon a remote computer user's input.

19 . A non-transitory computer readable storage medium storing computer readable program code, wherein, when executed by a processor, the computer readable program code:
receives from a wireless positioning module the location within the facility of an industrial vehicle; receives the speed of the industrial vehicle from a speed sensor; receives from a remote computer via a communications network a speed limit and an associated restricted speed zone; stores in the non-transitory computer readable storage medium the speed limit and the restricted speed zone; generates a speed warning when the industrial vehicle exceeds the speed limit while located within the restricted speed zone; and transmits a non-compliance message to the remote computer via the communications network when the operator fails to comply with the speed warning; wherein the remote computer is configured for setting the speed limit and the speed restriction zone based upon a user's input.

20 . A speed-limit-compliance method for an industrial vehicle driven by an operator, comprising:
receiving from a wireless positioning module the location within a facility of the industrial vehicle; receiving the speed of the industrial vehicle from a speed sensor; receiving from a remote computer via a communications network a speed limit and an associated restricted speed zone; storing in a non-transitory computer readable storage medium the speed limit and the restricted speed zone; generating a speed warning when the industrial vehicle exceeds the speed limit while located within the restricted speed zone; and transmitting a non-compliance message to the remote computer via the communications network when the operator fails to comply with the speed warning; wherein the remote computer is configured for setting the speed limit and the speed restriction zone based upon a user's input.
