Abstract
The invention relates to a rolling handling machine (1) having an arm. The machine comprises an alert system comprising a memory in which are stored a plurality of alert rules for triggering at least one action from among transmitting data relating to the determined values of said parameters to a remote server (31); and emitting a visual, and/or sound, and/or vibration signal to alert the machine's driver. The triggering of an action occurs according to the speed of movement of the machine and the angular position of the arm. The invention also relates to an alert method and to a corresponding program product.
Claims13
A handling machine (1) comprising:
- a wheeled chassis (2);
- a lifting arm (6) articulated to the wheeled chassis (2) so as to be able to be pivoted between a lowered position and a raised position,
- characterized in that the machine (1) also comprises a system (10, 111, 112) for determining values of parameters of the machine, configured to determine values of a group of parameters comprising:
- a parameter relating to the speed of movement of the machine;
- and
- a parameter relating to the angular position of the arm (6);
- said machine being configured to make it possible to trigger at least one warning action from the following group of actions:
- transmission to a remote server (31) of data relating to the determined values of said parameters;
- and
- emission of a visual, and/or audible, and/or vibratory signal to warn the driver of the machine;
- the machine (1) also comprising a warning system having a memory in which a plurality of warning rules are stored,
- the plurality of warning rules comprising:
- a first rule according to which a first action of said group of actions or a first set of actions of said group of actions is triggered when the values of said parameters exceed a first set of threshold values;
- a second rule according to which a second action of said group of actions, distinct from the first action, or a second set of actions of said group of actions, comprising at least one action distinct from said first action or distinct from an action of said first set of actions, is triggered when the values of said parameters exceed a second set of threshold values.
A method for warning of driving risk, in particular of risk of tipping over, for a handling machine (1) comprising a wheeled chassis (2) and a lifting arm articulated to the wheeled chassis (2) so as to be able to be pivoted between a lowered position and a raised position, characterized in that the method comprises the following steps:
- determination of first values of the parameters of speed of movement and of arm angle of the machine;
- comparison of the first determined values of said parameters with first threshold values,
- as a function of the result of the comparison, triggering at least one first warning action from the following group of actions:
- transmission to a remote server (31) of data relating to the determined values of said parameters;
- and
- emission of a visual, and/or audible, and/or vibratory signal to warn the driver of the machine;
- the method also comprising the steps of:
- determination of second values of said parameters of the machine;
- comparison of the second determined values of said parameters with second threshold values;
- as a function of the result of the comparison, triggering at least one second action, different from said at least one first action, from said group of actions.
