Central Data Acquisition and Control System
The eLINK is a central control and data acquisition system that has three communication channels: with the user through a web application connected to any mobile device, be it PC, tablet and/or smartphone; with the elements of the crane through 8 input channels and 4 output channels; and with the lifting hooks through radio communication. It is installed in the crane panel itself, with which we can directly make the appropriate connections of the crane elements that we want to control (such as the Interlock), using the 8 inputs and 4 outputs controlled by relay.
The main operating function is the control of the lifting hooks, either individually or in groups, through the web application. This allows the user to perform different logical functions through the inputs and outputs that are connected to the eLINK, in order to improve the control of the different scenarios that need to be managed. The device itself generates a Log file which informs of all the events that are carried out while the eLink is operating, saving each event with date and timestamp thanks to the Real Time Clock that the device carries.
Communication with User
· eLINK serves a Web App
· local or global access
· user & password login
· different profiles/access levels (user, admin, service, factory)
· users can connect using Wi-Fi, Bluetooth, 4G
· compatible with Windows, MacOS, iOS & Android
· link hooks
· set up hooks
· access hook status
· access hook log files
· control hooks (open/close)
· set up logical rules
· set up relays
· set up inputs
Communication with the Crane’s Elements
Crane control by CANbus or 4 output relays
User defined logical rules, using the hook’s sensor information, can be used to automate crane behaviour.
examples: (amongst many other possibilities)
– if Hook #1 is not fully open/closed, then block the crane.
– if Hook #1 has an overload, then block the crane and sound the alarm.
– if Hook #1 and Hook #2 are not in the same state, then block the crane.
– if the temperature of hook #1 is >80ºC, then sound the alarm.
