Method and arrangement for control and evaluation of the operation of a lift
An automated method to control and evaluation of the operation of a lift installation, where at least one load of unknown weight is weighed by means of a weighing machine; the sum of the weights detected on site in the lift installation where the maintenance work is being performed is transmitted to a portable control console, which transmits the sum of the weights detected associated with the loads introduced to the lift cabin to a load weighing device; to receive command signals associated with the control and maintenance tasks transmitted from the portable control console, in response to operating parameters of the lift cabin loaded with the sum of the weights detected.
1. An automated method of control and evaluation of the operation of a lift installation, characterised in that the method comprises the steps of
Weighing a load of at least one weight by means of a weighing machine ( 6 );
Transmission via a data emitter ( 7 ), included in the weighing machine ( 6 ), of the sum of the weights detected on site in the lift installation where the maintenance work is being performed, to a portable control console ( 5 );
Transmission via a data transmitter-receiver, included in the portable control console ( 5 ), to a load weighing device ( 1 ) of the sum of the weights detected associated with the loads inserted in the lift cabin ( 2 ); and
Receipt via a data emitter-receiver ( 4 ), included in the load weighing device ( 1 ), of command signals associated with the control and maintenance tasks, transmitted from the portable control console ( 5 ), as a response to operating parameters of the lift cabin ( 2 ) loaded with the sum of the weights detected.
2. An automatic arrangement for control and evaluation of the operation of a lift installation; characterised in that the arrangement comprises a weighing machine ( 6 ) adapted to weigh unknown loading weights outside a lift cabin ( 2 ); the weighing machine ( 6 ) includes a data emitter ( 7 ) adapted to transmit the sum of the weights detected on site in the lift installation where maintenance work is being performed to a portable control console ( 5 ) which includes a data transmitter-receiver adapted to transmit the sum of the weights detected associated with the loads introduced to the lift cabin ( 2 ) to a load weighing device ( 1 ) which receives, via a data emitter-receiver ( 4 ), command signals associated with control and maintenance tasks from the portable control console ( 5 ), as a response to the operating parameters of the lift cabin ( 2 ) loaded with the sum of the weights detected.
3. An arrangement as per claim 1 , characterised in that the load weighing device ( 1 ) includes a communications port ( 3 ) of the USB port type that can be connected to the data emitter receiver ( 4 ).
4. An arrangement as per claim 2 , characterised in that the automatic control arrangement uses a wireless communications protocol of the Wi-Fi or Bluetooth type.
