The Internet system has been designed to be a complete solution for lift monitoring, whether on site (i.e. building management), or from a remote location. It utilises the Internet to make use of the latest technology, but also to make use of the Internet protocols, which allow multi user connections, i.e. many persons are able to connect to one lift site, all at the same time. The user can connect via Broadband (for speed), telephone, mobile phone (GSM), or local network (Intranet). In the event of Internet failure the system can also revert back to using normal telephone connections.
The system has features to allow Monitoring, System Interrogation, and Programming. Monitoring can be of the lifts themselves, of the inverter drive connected to the lift, or of the lift IO system.
System Interrogation involves transferring information such as the lift setup, also the transfer of the Event History (lift and drive) to diagnose problems that have occurred, even before going to site. This has the advantage of arming the user with as much information as possible and predicting future failures. The Internet Board (IP Board) itself pays special attention to fault logging, since connection problems and the complexity of the Internet, requires detailed logging to trace connection / setup problems.
System programming can also be achieved remotely, as / when required. This feature is password protected to safeguard against nuisance / accidental system overwriting or corruption. However changing system parameters, adding to or removing from the system, and setting up the drive (speed profiles etc.) are achievable.
System software upgrade is also available, however restricted to Lester Controls personnel only. This can be used to upgrade the system for the addition of new features, or changing system software. The upgrade has also been carefully designed to ensure that the corruption of transferred software shall not affect the upgrade. The existing software is always retained, and not overwritten, despite the upgrade.
The Internet Board microprocessor has been designed using surface mount component technology to be small and compact. The hardware will fit into an Almega rack as standard, but may be mounted externally to suit other Lester Control Systems controllers.
The Windows application software is necessary for Internet / remote connectivity. The software will work on any IBM compatible P.C. or laptop (250MHz or higher) with windows version XP.
