Abstract

Operation of an industrial vehicle is managed by systems onboard that vehicle. One such management system monitors operation of vehicle components and produces performance data which is transmitted to an computer at the facility in which the industrial vehicle operates. That system includes an interface module with a plurality of inputs for receiving signals from components on the industrial vehicle. The interface module derives performance data from the signals and conveys the performance data over a communication network. A data acquisition module receives the performance data from the communication network and has a communicator for wirelessly transmitting the performance data.

Claims

1. A system for acquiring performance data from industrial vehicles having different respective standardized communication protocols, wherein a first industrial vehicle includes a first vehicle controller operatively connected to control a plurality of components and configured to communicate using a first vehicle communication network and adapted to transmit vehicle data using a first standardized network communication protocol, wherein a second industrial vehicle includes a second vehicle controller operatively connected to control a second plurality of components and configured to communicate using a second vehicle communication network and adapted to transmit second vehicle data using a second standardized network communication protocol, said system comprising:

a data acquisition module not compatible with the first standardized communication protocol of the first industrial vehicle to receive the vehicle data, the data acquisition module having a port adapted to removably connect to the second standardized communication network of the second industrial vehicle and receive vehicle data that is transmitted using the second standardized network communication protocol, and the data acquisition module having a communicator for wirelessly transmitting the vehicle data; and

an interface module having an input for connecting to an output signal from at least one of the plurality of components on the first industrial vehicle, the plurality of components on the first industrial vehicle in communication with the first vehicle controller via the first vehicle communication network, wherein the interface module derives the vehicle data from the output signal, and communicates the vehicle data using a network interface removably connected to the port to convey the vehicle data to the data acquisition module using the second standardized network communication protocol.

2. The system as recited in claim 1 wherein the communicator periodically transmits the vehicle data.

3. The system as recited in claim 1 wherein the interface module has a plurality of inputs for connecting to a plurality of output signals from the plurality of components on the first industrial vehicle in communication with the first vehicle controller via the first vehicle communication network;

and further comprising a storage device containing an input mapping table designating a relationship between each of the plurality of inputs and each of the plurality of components.

4. The system as recited in claim 3 wherein at least one of the plurality of components comprises a sensor.

5. The system as recited in claim 3 wherein the interface module has a programming port for connection to a device for changing the input mapping table.

6. The system as recited in claim 1 wherein the interface module derives the vehicle data from the output signal by measuring an amount of time that the signal is active.

7. The system as recited in claim 1 wherein the communicator transmits the vehicle data in response to occurrence of a predefined event.

8. The system as recited in claim 1 wherein the interface module further comprises:

a processor connected to the network interface; and

an input circuit connected to the processor and having a plurality of inputs for receiving a plurality of output signals from the plurality of components on the first industrial vehicle in communication with the first vehicle controller via the first vehicle communication network.

9. The system as recited in claim 1 further comprising:

a first communication circuit connected to another component on the first industrial vehicle for sending data messages through a power line through which electrical power is supplied to the first industrial vehicle components; and

a second communication circuit for receiving the data messages that were sent through the power line.

10. A system for acquiring performance data from industrial vehicles having different respective standardized communication protocols, wherein a first industrial vehicle includes a first vehicle controller operatively connected to control a plurality of components and configured to communicate using a first vehicle communication network and adapted to transmit vehicle data using a first standardized network communication protocol, wherein a second industrial vehicle includes a second vehicle controller operatively connected to control a second plurality of components and configured to communicate using a second vehicle communication network and adapted to transmit second vehicle data using a second standardized network communication protocol, said system comprising:

a data acquisition module not compatible with the first standardized communication protocol of the first industrial vehicle to receive the vehicle data, the data acquisition module having a port adapted to removably connect to the second standardized communication network of the second industrial vehicle and receive vehicle data that is transmitted using the second standardized network communication protocol, and the data acquisition module having a communicator for wirelessly transmitting the vehicle data; and

an interface module separate from the first vehicle controller and having a plurality of inputs for connecting to a plurality of output signals from the plurality of components on the first industrial vehicle, the plurality of components on the first industrial vehicle in communication with the first vehicle controller via the first vehicle communication network, wherein the interface module derives the vehicle data from the plurality of output signals, and communicates the vehicle data using a network interface removably connected to the port to convey the vehicle data to the data acquisition module using the second standardized network communication protocol.

11. The system as recited in claim 10 wherein the interface module further comprises a storage device containing an input mapping table designating a relationship between each of the plurality of inputs and each of the plurality of components.

12. The system as recited in claim 11 wherein the interface module has a programming port for connection to a device for changing the input mapping table.

13. The system as recited in claim 10 wherein the interface module derives the vehicle data from at least one of the output signals by measuring an amount of time that the at least one of the output signals is active.

14. The system as recited in claim 10 wherein the interface module comprises:

a processor connected to the network interface; and

an input circuit connected to the processor and having the plurality of inputs.

15. The system as recited in claim 10 wherein the communicator periodically transmits the vehicle data.

16. The system as recited in claim 10 wherein the port of the data acquisition module is isolated from the plurality of output signals in communication with the first vehicle controller.
