Stability monitoring function for a thick matter conveying system

A thick matter conveying system (10) further comprising:

• a thick matter pump (16) for conveying thick matter, comprising a double-piston core pump (15) having a pump frequency, and an S-pipe (24) which is switchable at the pump frequency,
• a thick matter distributor mast (18) for distributing the thick matter to be conveyed, wherein the thick matter distributor mast (18) has at least two mast arms (41),
• a substructure (30) on which are disposed the thick matter distributor mast (18) and the thick matter pump (16), wherein the substructure (30) comprises a support structure (31) for supporting the substructure (30) by way of at least one horizontally and/or vertically displaceable support leg (32),
• a sensor unit (11) for sequentially capturing at least one item of operational information at at least a first and a second point in time,
• a processing unit (12) which determines a stability parameter of the thick matter conveying system (10) depending on the at least one item of operational information captured at the first point in time, the at least one item of operational information captured at the second point in time, and the pump frequency, and
• a control unit (13) for emitting a first control signal if the determined stability parameter of the thick matter conveying system (10) is greater than a maximum stability parameter of the thick matter conveying system (10), and to emit a second control signal if the determined stability parameter of the thick matter conveying system (10) is less than or equal to the maximum stability parameter of the thick matter conveying system (10).

A method (100) for operating a thick matter conveying system (10) which comprises a thick matter pump (16) for conveying a thick matter, a thick matter distributor mast (18) for distributing the thick matter to be conveyed by way of at least two mast arms (41), a substructure (30) on which are disposed the thick matter distributor mast (18) and the thick matter pump (16), a sensor unit (11) for sequentially capturing at least one item of operational information, a processing unit (12), and a control unit (13), wherein the thick matter pump (16) comprises a double-piston core pump (15) having a pump frequency, and an S-pipe (24) which is switchable at the pump frequency, and wherein the substructure (30) comprises a support structure (31) for supporting the substructure (30) by way of at least one horizontally and/or vertically displaceable support leg (32), the method comprising the following steps:

• sequentially capturing, by the sensor unit (11), at least one item of operational information at at least a first point in time (101b) and a second point in time (101a),
• determining (104), by the processing unit (12), a stability parameter of the thick matter conveying system (10) depending on the item of operational information captured at the first point in time, the item of operational information captured at the second point in time, and the pump frequency,
• emitting (105), by the control unit (13) of the thick matter conveying system (10), a first control signal if the determined stability parameter of the thick matter conveying system (10) is greater than a maximum stability parameter of the thick matter conveying system (10), and
• emitting (106), by the control unit (13), a second control signal if the determined stability parameter of the thick matter conveying system (10) is less than or equal to the maximum stability parameter of the thick matter conveying system (10).
