(ACN refers to Access Control Node, a physical node attached to a tool)

I plan to

  • Base the device on the Duemilanove arduino as it fits our needs and has a wide base of users.
  • Use the wiznet chip for ethernet support
  • Use i2c sm030 rfid readers
  • allow different control outputs (relay, Darlington, servo control etc)
  • use eeprom memory for internal storage

Services

Mission critical

These must function without networking or main server available:

  • Check if card in ACN local db and allow use if is
  • Set tool into "out of order" mode

Non critical

  • Add cards
  • Report back to central server (usage etc)

Progress

I have made a prototype shield for testing code while the full design remains to be tested and produced. http://www.flickr.com/photos/solexious/6865500239/

Design for the full ACNode at: https://github.com/solexious/ACNode

Incomplete implementation of server side is hosted here: https://github.com/asokoloski/tacserv

Incomplete python version: https://github.com/londonhackspace/ACNode

Network protocol

This is mostly RESTful, but not entirely because we're using text/plain (for the small atmega). In particular, the /sync request could actually use /card with weird Range headers, but that's pretty awkward. It should be easy to upgrade to a full JSON or hypertext system.

Get card permissions

GET /[nodeID]/card/

i.e.

  • GET /1/card/04FF7922E40080

returns

  • 0 - no permissions
  • 1 - user
  • 2 - maintainer

STATUS: Done

Add card

POST /[nodeID]/grant-to-card/[card_being_granted_to]/by/[card_with_admin_permissions]

i.e.

  • POST /1/grant-to-card/04FF7922E40080/by/04FF792AAAAAA

returns

  • 0 - card not added
  • 1 - card added

STATUS: Done - but not yet tested

Check DB sync

GET /[nodeID]/sync/

Returns first card in db

i.e.

  • GET /1/sync/

returns the first card in the DB i.e.

  • 04FF7922E40080

GET /[nodeID/sync/[last received card]/

i.e.

  • GET /1/sync/04FF7922E40080/

returns either the next card in DB i.e.

  • 03FF7922FF008F

or when out of cards returns

  • END


STATUS: Done - tested on UI, but not with ACNode

Report tool status

POST /[nodeID]/status/[new_status]/by/[cardWithAdminPermissions]

i.e.

  • PUT /1/status/0
  • 0 - out of service
  • 1 - in service

returns

  • 0 - not saved
  • 1 - saved

STATUS: Not yet done

Check tool status

GET /[nodeID]/status/

Check if the ACNode has been remotely taken out of service, or put back in service

returns

  • 0 - out of service
  • 1 - in service

STATUS: Done - tested on UI, but not with ACNode

Tool usage (live)

POST /[nodeID]/tooluse/[status]/by/[cardID]

i.e.

  • POST /1/tooluse/0/04FF7922E40080

Status is one of:

  • 0 - tool use stopped
  • 1 - tool in use

returns

  • 0 - not saved
  • 1 - saved

STATUS: Not yet done

Tool usage (usage time)

POST /[nodeID]/tooluse/time/for/[cardID]/[timeUsed]

i.e.

  • POST /1/tooluse/time/for/04FF7922E40080/34000

returns

  • 0 - not saved
  • 1 - saved

STATUS: Not yet done

Case alert

POST /[nodeID]/case/change/[new_status]

i.e.

  • PUT /1/case/1

Alert if the ACNode case is opened

  • 0 - case closed
  • 1 - case opened

returns

  • 0 - not saved
  • 1 - saved


STATUS: Not yet done
