Dial-in Internet Access

A telecom link between the piggery in Australia and a local dial-in internet access provider establishes the contact to the internet and the traffic control system. The connection may stay open for the entire 24-hour event, reducing the time delay between switch activation and traffic light control, and allowing additional features to be implemented, such as a web camera for World Wide Web users.
 

Alternatively, the PORCONTROL signal and a photo captured with a web camera can be submitted as an email containing a CGI form. The connection would be opened when the switch is pushed, and closed after a certain period of inactivity. However, this method has a larger time delay and may produce login failures at a time when nobody is around to step in.

Key problems to be solved:

  • What is the best method of connection?
  • How can the PORCONTROL protocol be combined with a web camera access?
