Abstract

A sewer cleaning machine includes a frame and a drum rotatably supported by the frame. The drum defines an opening. The sewer cleaning machine also includes a cable supported within the drum and is operable to enter and exit the drum through the opening. The cable includes a plurality of tags spaced along a length of the cable. The sewer cleaning machine further includes a reader module positioned adjacent the opening. The reader module is operable to identify each of the plurality of tags as the plurality of tags passes the reader module and communicate to a user a distance the cable is payed out of the drum based on the plurality of tags.

First claim

What is claimed is:

1 . A sewer cleaning machine comprising:
a frame; a drum rotatably supported by the frame, the drum defining an opening; a cable supported within the drum and operable to enter and exit the drum through the opening, the cable including a plurality of tags spaced along a length of the cable; and a reader module positioned adjacent the opening, the reader module operable to identify each of the plurality of tags as the plurality of tags passes the reader module and communicate to a user a distance the cable is payed out of the drum based on the plurality of tags.

2 . The sewer cleaning machine of claim 1 , further comprising:
a motor supported by the frame and coupled to the drum to rotate the drum; and a power supply operable to energize the motor to rotate the drum.

3 . The sewer cleaning machine of claim 2 , wherein the power supply is a removable battery pack.

4 . The sewer cleaning machine of claim 1 , wherein each tag of the plurality of tags is a radio frequency identification tag.

5 . The sewer cleaning machine of claim 1 , wherein each tag of the plurality of tags includes a unique identification code.

6 . The sewer cleaning machine of claim 5 , wherein each unique identification code is associated with a distance on the cable.

7 . The sewer cleaning machine of claim 1 , wherein the plurality of tags is spaced at equal intervals along the length of the cable.

8 . The sewer cleaning machine of claim 7 , wherein each tag of the plurality of tags is spaced one foot relative to an adjacent tag of the plurality of tags.

9 . The sewer cleaning machine of claim 1 , wherein the reader module includes a display operable to display the distance the cable is payed out of the drum.

10 . A cable counter for a sewer cleaning machine including a drum, the cable counter comprising:
a cable including a plurality of tags spaced along a length of the cable, each tag including a unique identification code; and a reader module operable to identify each tag of the plurality of tags, the reader module including
an antenna to detect each tag of the plurality of tags as the cable passes the antenna,
a tag reader in communication with the antenna to determine the unique identification code of each tag of the plurality of tags,
a processor in communication with the tag reader to compare the unique identification code of each tag of the plurality of tags to unique identification codes stored within a memory of the processor, and
a display in communication with the processor to display information associated with the unique identification code of each tag of the plurality of tags to a user.

11 . The cable counter of claim 10 , wherein the plurality of tags is spaced at equal intervals along the length of the cable.

12 . The cable counter of claim 10 , wherein the information associated with the unique identification code of each tag of the plurality of tags includes the distance the cable is payed out from the drum.

13 . The cable counter of claim 10 , wherein the information associated with the unique identification code of each tag of the plurality of tags includes a size of the cable.

14 . The cable counter of claim 10 , wherein the information associated with the unique identification code of each tag of the plurality of tags includes a type of cable.

15 . A method of operating a sewer cleaning machine, the sewer cleaning machine including a drum having an opening, a cable supported within the drum and having a tag with a unique identification code, and a reader module supported adjacent the opening, the method comprising:
moving the cable relative to the drum through the opening; sensing, by an antenna of the reader module, the tag as the tag passes the reader module; determining, by a tag reader of the reader module, the unique identification code of the tag sensed by the antenna; comparing, by a processor of the reader module, the unique identification code of the tag with unique identification codes stored within a memory of the processor; and displaying, by a display, information associated with the unique identification code of the tag to a user.

16 . The method of claim 15 , wherein the tag is one of a plurality of tags spaced along a length of the cable.

17 . The method of claim 16 , further comprising determining, by the processor, a direction of movement of the cable by comparing a unique identification code of a previously detected tag of the plurality of tags with the unique identification code of the currently detected tag of the plurality of tags.

18 . The method of claim 17 , further comprising communicating, by the display, the direction of movement of the cable to the user.

19 . The method of claim 15 , wherein the information associated with the unique identification code of the tag includes a distance the cable is payed out from the drum.

20 . The method of claim 15 , wherein the display is part of the reader module.
