Definitions

  • the invention relates to a method for ringing at least one bell driven by a motor, according to which a series of positions is established, each position marking an angle in the rotation of the axis of the motor, and in which a first control signal is produced each time the motor axis has reached one of the positions of said series and, under the control of each first control signal, a parameter for the direction of rotation of the motor axis is determined.
  • the invention also relates to a device for implementing the method.
  • a disadvantage of the known method is that it is relatively complex and that it does not always lead to a good movement of the bell.
  • the imposed value of the amplitude must in fact be reached precisely either directly or continuously. This causes engine management to be very critical.
  • this movement of the bell is, on the one hand, unnecessarily limited and is, on the other hand , not set correctly to allow the bell to ring regularly.
  • the control between the two directions of movement of the bell is performed separately, which makes this control all the more complicated.
  • the object of the invention is to provide a process which depends less directly on this critical value.
  • a method is characterized in that, under the control of each first control signal, a bell movement parameter indicating the instantaneous direction of movement of the bell is determined, and the direction of rotation parameter, respectively the bell movement parameter, is stored at least temporarily, and in that from the stored direction of rotation parameter it is checked whether the motor axis has substantially retained its direction of rotation during a period during which a predetermined number first successive control signals have been produced and when it has been observed that the direction of rotation has been substantially retained during said period, a parameter of movement of the bell is determined which corresponds to said direction of rotation and it is checked whether said parameter of bell movement, which corresponds to said direction of rotation, corresponds to the bell movement parameter determined during the first s control signal produced last and, in the event of discrepancy, a second control signal is produced to determine an energy supply to the motor.
  • first and second control signals makes it possible to monitor the movements of the bell and the motor and therefore provides the possibility of adjusting them in the event that a gap has been established. Thanks to this, it is no longer necessary to monitor this critical value.
  • a first preferred embodiment of the method according to the invention is characterized in that, after each lapse of predetermined interval of time, a third control signal is produced under control of which at least one function of the motor is checked. This also makes it possible to introduce monitoring over time.
  • the method according to the invention is characterized in that, in the event of discrepancy, a first amplitude belonging to a first direction of movement of the bell is determined. This makes it possible to establish each time a value for the predetermined amplitude as a function of the circumstances such as climatic or other circumstances.
  • the method according to the invention is characterized in that, under control of the second control signal, the instant at which a change of direction in the movement of the bell takes place is each time stored.
  • a fourth embodiment of a method according to the invention is characterized in that, under control of the second control signal, on the basis of at least one of the parameters, the bell movement parameter determined in case of discrepancy, either the parameter indicating the number of changes of direction, or the adjustment parameter, an amount of energy to be supplied as well as a distance from the movement of the bell to which the energy must be supplied. Said energy supply can thus each time be determined for each case of the successive stages of the movement of the bell.
  • a fifth preferred embodiment of a method according to the invention which, to ring the bell, comprises a start-up phase, a speed phase and a braking phase and in which each phase has its own adjustment parameter, is characterized in that for each phase said energy to be supplied and the spacing are determined on the basis of the adjustment parameter specific to this phase.
  • a second amplitude of the movement of the bell is determined according to a second movement thereof, the difference between at least first two and second successive amplitudes is determined and it is checked whether this difference exceeds a predetermined value and, in this case, an average is determined which is imposed as the equilibrium position of the movement of the bell.
  • a correction is applied to the control of the motor as a function of the established equilibrium position.
  • At least one of the operating parameters of the motor, rotation speed and motor current is respectively imposed on one of the parameters of movement of the bell, a first respectively a second pair of limit values, and, under control of said first control signal, it is checked whether said motor operating parameters are included in said first pair of limit values and, under control of said second control signal, it is checked whether the movement spacing of the bell is included in said second pair of limit values and, in the event of discrepancy, an alarm signal is produced.
  • the moments at which the second respectively the third control signal is produced are each time determined and the difference between the moment at which the third signal and a second signal that precedes it are products is determined, and it is checked whether said difference exceeds a predetermined value and whether such an alarm signal is produced during such a finding.
  • the motor is deactivated under control of said alarm signal.
  • FIG. 1 illustrates schematically, an example of a device leaving the invention, the device comprises a bell 11 with a leaf 19. Said bell is driven by a motor (3), for example an asynchronous electric motor.
  • the bell is mounted on a seat 16, which forms the chassis, and is suspended by means of an axis 15.
  • On the axis 15 is mounted a wheel 17 which is connected by means of a transmission member, such as for example a chain 18 to axis 30 of the engine.
  • the motor drives the bell via the transmission member.
  • the motor is connected to a connection unit 40.
  • the connection unit is provided with an input 12 to which a power source is connectable, such as for example the electrical network.
  • the device also includes a sensor 24 for detecting the movement of the motor.
  • This sensor has an output connected to a first input of a processing unit 25, which has a second input intended to connect a control member 20, for example a keyboard and a display unit, for example a CD .
  • An output of the processing unit 25 is connected to the connection unit 40, thus making it possible to form a closed control loop comprising the motor, the sensor, the connection unit and the processing unit. Thanks to this closed control loop, it is possible to monitor the movement of the motor and therefore of the bell connected to it and also to adjust this movement as will be described below.
  • Figure 2 shows an exemplary embodiment of a sensor.
  • This comprises a notched disc 5, which is mounted on the axis of the engine.
  • Two rays of light 32 substantially parallel to each other, are oriented substantially perpendicular to the plane of the disc 5 at the height of the teeth of the latter.
  • the teeth correspond to a series of positions in the movement of the motor axis.
  • the rotation of the motor axis drives the disc, which, in turn, intermittently interrupts the passage of the transmitted light beams. Photodiodes detect this interruption and this transmission of the light beams.
  • the disc is chosen so that every 7 ° 30 'there is a change in the detected signal.
  • the processing unit 2 comprises a data processor, for example a microprocessor, which, in a well-known manner, is provided with a memory as well as an input-output interface.
  • This data processing unit allows the control of the motor and thus that of the movement of the bell.
  • the program which has just been described is executed each time a first control signal has been produced, thus allowing monitoring of the movement of the bell and rapid intervention in the event of movement disturbance.
  • the production of the second signal when an anomaly has been observed, will make it possible to determine an energy supply allowing to restore a balanced movement of the bell.
  • the determination of a new equilibrium situation makes it possible to calculate the amplitude values relative to this new equilibrium situation specific to the bell, rather than starting from a theoretical equilibrium.
  • the energy input to the motor is also determined under the control of the processing unit. To this end, control programs are stored in the memory.
  • Figures 4 and 5 show a flow diagram of the different stages in which, according to the invention, the supply of energy to the motor is determined.
  • the resumed programs are started (STR) under control of the second control signal.
  • a distance is determined between an amplitude of the current bell and the predetermined amplitude.
  • it is checked whether the spacing is less than an established value, for example -60 °. If this is determined, this established value is assigned to this spacing.
  • the energy to be supplied to the motor is determined as the sum of two fractions.
  • a first fraction is proportional to the deviations accumulated between the established amplitude and the current amplitude. This first fraction can never be greater than a predetermined maximum value nor less than a predetermined minimum value. If this first part were to be less than respectively greater than this value minimum respectively maximum, this respectively maximum minimum value (ST4) is imposed. A non-linear limitation is thus formed for this first fraction.
  • a second fraction is proportional to the current deviation between the established amplitude and the current amplitude. The sum of the two fractions is also limited to extreme values. The total energy supply is then distributed over the two directions of movement of the bell, if necessary asymmetrically, the proportion of which is adjustable.
  • the total duration of activation of the motor is then the sum of the respective parts P and I, which follows from the succession of steps ST2 and ST3.
  • This activation time is then in ST4, respectively in ST5, distributed in a first, respectively a second, without movement, opposite to the first, of the bell according to an "asymmetrical" parameter.
  • the activation time in said first direction is determined in ST4 as a product of said pulse quantity with said asymmetrictempoual parameter. In ST4, it is also checked whether the pulse quantity is negative. If this is the case, it is assigned the value zero.
  • the activation time in said second direction is determined in ST5 as a product of said pulse quantity with amital asymmetric parameter factor. In addition, we check in ST5 if this pulse quantity is negative. If this is the case, said value of pulse is assigned zero. This again forms a non-linear limit for the regulator. The position to which the motor is supplied can now be established using the "establishment value" parameter determined in ST6.
  • Figure 5 illustrates the case of the stopped bell.
