Abstract

A control system for an industrial vehicle includes a badge communicator and an information linking device. The badge communicator has a transceiver for short range communication with electronic badges that are within a fixed short range of the badge communicator, defining a first zone. The information linking device is programmed to execute program code. The program code extracts a current state of an operating parameter read from an industrial vehicle network bus, generates a second zone within the first zone that is defined based upon the extracted industrial vehicle operating parameter, detects a presence of an electronic badge within the first zone, determines whether the electronic badge is within the second zone, performs a first action if the detected electronic badge is not within the second zone, and performs a second action if the electronic badge is within the second zone.

First claim

What is claimed is:

1. A process for controlling an industrial vehicle, the process comprising:
receiving, by a stationary badge communicator, vehicle data that is transmitted from a remote mobile industrial vehicle via a first communications protocol upon the mobile industrial vehicle traveling within a predetermined range of the stationary badge communicator, wherein:
the stationary badge communicator is mounted at a stationary location within an environment upon which the mobile industrial vehicle operates;
the first communications protocol enables direct local wireless communication between the badge communicator and the mobile industrial vehicle using Bluetooth, Ultra-wideband (UWB), or Zigbee; and
the vehicle data includes:
an identity of an electronic badge, an identity of the industrial vehicle, or an identity of a vehicle operator;

sending, from the badge communicator to a remote server, a first message based on the received vehicle data and an identity of the badge communicator via a second communications protocol that is different from the first communications protocol;
receiving, at the industrial vehicle, responsive to the exchange between the badge communicator and the remote server, an electronic communication comprising an instruction, wherein the electronic communication is sent from the remote server, and includes instructions based on the first message and based on rules concerning the operation of the industrial vehicle; and
controlling the industrial vehicle to take a predetermined action based upon the instruction.

2. The process of claim 1 , wherein the first message is conveyed over a direct communication between the stationary badge communicator and the remote server.

3. The process of claim 1 , wherein the stationary badge communicator forms part of a mesh network.

4. The process of claim 3 , wherein communication between the stationary badge communicator and other nodes within the mesh network takes place using the second communications protocol.

5. The process of claim 3 , wherein communication between the stationary badge communicator and other nodes within the mesh network takes place using a third communications protocol.

6. The process of claim 1 , further comprising a mobile electronic badge that is in communication with the industrial vehicle over the first communications protocol to exchange data corresponding to a relative position between them.

7. The process of claim 1 , wherein the rules are part of a warehouse management system.

8. The process of claim 1 , wherein the vehicle data received at the stationary badge communicator is transmitted from an electronic badge, wherein the vehicle data further comprises time stamp data.

9. The process of claim 1 , wherein the vehicle data received at the stationary badge communicator is transmitted from an electronic badge, wherein the vehicle data further comprises position data.

10. The process of claim 1 , wherein controlling the industrial vehicle comprises automatically adjusting the top speed of the industrial vehicle.

11. The process of claim 1 , wherein controlling the industrial vehicle comprises automatically prohibiting the industrial vehicle from entering an exclusionary zone within a warehouse.

12. The process of claim 1 , wherein the rules include rules based on collision avoidance.

13. A process for controlling an industrial vehicle, the process comprising:
receiving, by a stationary badge, vehicle data that is transmitted from a remote mobile industrial vehicle via a first communications protocol upon the mobile industrial vehicle traveling within a predetermined range of the stationary badge, wherein:
the stationary badge is mounted at a fixed, stationary location within an environment upon which the mobile industrial vehicle travels;
the first communications protocol enables direct wireless local communication between the remote mobile industrial vehicle and the stationary badge independent of a remote server; and
the vehicle data includes:

an identity of an electronic badge communicator, an identity of the industrial vehicle or an identity of a vehicle operator;

sending, from the stationary badge to the remote server, a first message based on the received vehicle data and an identity of the stationary badge via a second communications protocol that is different from the first communications protocol;
receiving, at the industrial vehicle, responsive to the exchange between the stationary badge and the remote server, an electronic communication from the remote server comprising an instruction based on the first message and based on rules concerning the operation of the industrial vehicle; and
controlling the industrial vehicle to take a predetermined action based upon the instruction.

14. The process of claim 13 , wherein controlling the industrial vehicle comprises automatically adjusting the top speed of the industrial vehicle.

15. The process of claim 13 , wherein controlling the industrial vehicle comprises automatically prohibiting the industrial vehicle from entering an exclusionary zone within a warehouse.

16. The process of claim 13 , wherein the rules include rules based on collision avoidance.

17. A process for controlling an industrial vehicle, the process comprising:
receiving, by a stationary badge, vehicle data that is transmitted from a remote mobile industrial vehicle via a first communications protocol upon the mobile industrial vehicle traveling within a predetermined range of the stationary badge, wherein:
the stationary badge is mounted at a fixed, stationary location within an environment upon which the mobile industrial vehicle travels;
the first communications protocol enables direct wireless local communication between the remote mobile industrial vehicle and the stationary badge independent of a remote server; and

sending, from the stationary badge to the remote server, a first message based on the received vehicle data via a second communications protocol that is different from the first communications protocol;
receiving, at the industrial vehicle, responsive to the exchange between the stationary badge and the remote server, an electronic communication from the remote server comprising an instruction based on the first message and based on rules concerning the operation of the industrial vehicle; and
controlling the industrial vehicle to take a predetermined action based upon the instruction.

18. The process of claim 17 , wherein controlling the industrial vehicle comprises automatically adjusting the top speed of the industrial vehicle.

19. The process of claim 17 , wherein controlling the industrial vehicle comprises automatically prohibiting the industrial vehicle from entering an exclusionary zone within a warehouse.

20. The process of claim 17 , wherein the rules include rules based on collision avoidance.
