Definitions

  • the present invention relates to an installation of control of one or more actuators equipped with asynchronous electric motors with auxiliary winding and capacitor and with two directions of rotation and equipped limit switches opening at the end of race, from impulse control points capable of delivering signals of two polarities different for controlling motor rotation one way or the other and each linked by a single control wire with at least one management module associated with the actuator and equipped with means of recognition of the polarity of the received signals, means of processing these signals and means of switching of the motor supply.
  • FIG. 1 An example of a conventional device known in the art for controlling an actuator A1, such as a motor, is shown in Figure 1.
  • This device is able to respond to a general order which is best given by two wires G1, G2, to which a third G0 wire (not shown) is currently being added. Its wiring is difficult to achieve.
  • module which usually includes a microcontroller and his diet.
  • the device to be able recognize a general command at all times, it it must be permanently supplied with so that unnecessary consumption is created and it becomes necessary to use components having a MTBF (mean time before failure) very high. this is particularly disadvantageous considering that the actual use of the function is very low, namely a few ten seconds a day.
  • control module receives a full periodic signal in the absence of control so that the consumption of the components is permanent and that these are exposed to network surges and noise.
  • the object of the invention is to improve the devices already known.
  • the object of the invention is more particularly to carry out a control installation which is better protected from transient overvoltages and shocks that can occur in the network of electrical distribution.
  • the installation is characterized in that the module management includes means of connection to the source supply responsive to received control signal and in that the supply of said management module is held through said end switches race.
  • the control installation may include at least one local control point with at least one switch control whose output line is connected to the input of the management module to transmit the local control, said local control point having in addition a triac mounted in parallel at the point of command and whose trigger allows the taking into account an external general command, consisting for example at a general control point with at least one control switch whose output line is connected to the triac trigger of the control point local.
  • the management module includes at least two relays acting on contacts allowing motor supply by phase depending on the command generated by said command points.
  • each relay is mounted in series with a diode, said diodes being antiparallel, a capacitor being mounted in parallel to relays and diodes, this capacitor is charging to activate one of the relays when the relay activation threshold is reached.
  • each relay has a capacitor in parallel and a transistor in series with a resistor, each transistor being connected to the input of the local control via a resistor and a diode to allow rapid discharge of capacitors when the transistors conduct, thus triggering the corresponding relay and interrupting the command activated.
  • the management module can be mounted in a point of control, in a junction box or be integrated to the actuator.
  • One of the advantages of the invention is that in the absence from a command from the command point, the management is not powered so that no energy is consumed by the installation.
  • Installation includes an SL1F one-touch control point, a BG management module and an actuator A1, such as a motor, and lines N for neutral, P for phase, CG for general control and CL for local order.
  • the control point is connected to the phase P, at the general order CG and issues its local control on the CL line.
  • the management module BG is connected to phase P, at the control point SL1F via line CL and neutral N.
  • the actuator is to him connected to the BG management module by the lines connected to contacts P1 and P2.
  • This engine control installation 1 includes a general control point 10, a local control 20 and a management module 30.
  • the impulse control point 10 shown in the figure 2 includes two control contacts PUSH UP 11 and DOWN 12, each of being mounted in series with a diode 14, 15, these diodes being antiparallel, and a control contact STOP 13 to stop the movement of the motor 1.
  • the point also includes a command output General CG linked to the local control point 20.
  • This local control point 20 also includes two MONTEE 21 impulse control contacts and DESCENT 22, each of them being mounted in series with a diode 24, 25, these diodes being antiparallel, and a STOP 23 control contact to stop the movement of the motor 1.
  • This control point 20 comprises furthermore a local control output CL connected to the management module 30.
  • This local control point 20 also comprises a single phase alternative P phase input, and a triac 26 mounted in parallel with the control contacts 21, 22 and 23 and the trigger of which is connected to the outlet of general command CG of the general control point 10.
  • the triac 26 trigger resistances are not shown to simplify the figure.
  • the operation of the motor 1 can be controlled either by local control point 20 or by general control point 10, and several local control can be ordered in parallel by a single general control point.
  • the operation of the local control point is the following: by the use of the control contacts 21, 22, 23 and diodes 24 and 25, the control output local CL respectively transmits a climb command during the positive half-waves of phase P feed, a descent order during negative phase alternations or a stop order, the contact 23 in this case connecting the CL output to positive and negative alternations of phase P. If a general command is given, then the triac 26 will cause the same operation as the contacts of command 11, 12, 13 via the general command output CG.
  • the management module 30 comprises two elements of RM, RD switching, e.g. current relays continuous acting on rm, rd contacts connected respectively on each of the supply lines P1, P2 of the two windings of motor 1, the motor being supplied with single-phase AC between P1 and N for the ascent and between P2 and N for the descent.
  • RD switching e.g. current relays continuous acting on rm, rd contacts connected respectively on each of the supply lines P1, P2 of the two windings of motor 1, the motor being supplied with single-phase AC between P1 and N for the ascent and between P2 and N for the descent.
  • FIG. 4 represents a first embodiment particularly simple management block. Of FCM up and FCD down limit switches are connected to line P1 for the climb and P2 for the descent, and the engine 1 is represented by a phase shift capacitor C1 and two windings 2 and 3. In this figure, a thermal switch CT allowing to cut the power of the motor 1 in case overheating is also shown.
  • two parallel branches comprising relays RD1, RM1 followed in series by diode D2D, respectively D2M, these two diodes being antiparalleles, are mounted in parallel with a capacitor C, the whole being in series with a resistance RP relative to the input of the control local CL.
  • the capacitor C charges or discharges at a voltage equal to the average mains voltage, positive or negative according to local control CL, divided by potentiometric ratio (RP, RD1) or (RP, RM1) across equivalent resistance RP // RD1 or RP // RM1. This charging voltage must be above the threshold relay activation.
  • the relay supply RM1 is maintained through FCM, C1, FCD and the diode D1M.
  • the order on the CL entry must however be maintained for some time to allow the engine to leave its end position and therefore allow the down limit switch FCD to close.
  • the motor then remains supplied as long that the FCM mounted limit switch is not not reached.
  • FCM rise, no more current flows in the diode D1M, and the current being below the threshold RM1 relay trip, rm1 contact opens then and the power supply to the engine is cut off.
  • FIG. 5 represents another embodiment of the management module.
  • This mode has the advantage of faster reaction to a STOP command thanks to the short circuiting of C1M or C1D by TM or TD.
  • the engine is shown diagrammatically by a phase shift capacitor C1 and two windings 2, 3, and limit switches (FCM for the climb and FCD for the descent) are connected to the lines P1 and P2 respectively.
  • a thermal switch CT cuts power to engine in case of overheating.
  • the management module similar to the module shown in Figure 3, has two low relays voltage RM2 and RD2 actuating contacts rm2 and rd2 located respectively on each of the lines supply P1, P2 of the two motor windings.
  • a C1M or C1D capacitor is placed in parallel with each relay RM2, RD2 so as to ensure the continuity of the holding current for a period from the sector, around 20 ms.
  • the time constant of the RM2 * CM product is typically 40 to 60 ms.
  • a D3M or D3D diode in series with an R3M resistor or R3D are used to allow rapid discharge of capacitors C1D and C1M. This discharge occurs at across resistors R2M, respectively R2D.
  • the resistance values are selected so that the discharge lasts less than 10 ms.
  • the operation of the management module is comparable to the operation described above for positive alternations.
  • diode D2D, relay RD2, resistor R1D, the capacitor C1D and diode D3M This current in the diode D3M has the effect of making the transistor TM conductor and therefore quickly discharge the capacitor C1M across resistor R2M, if the C1M capacitor was charged.
  • the charge of capacitor C1D slows the growth of the voltage across relay RD2, and you will have to wait some time, about 100 ms, so that the current relay RD2 has been reached and the contact rd2 is closed.
  • the values of the different components can be easily determined by a person skilled in the art taking mainly into account characteristics of the actuator controlled, for example of the motor.
  • the invention is not limited to the modes of execution described but variations are possible in the protection claimed. For example, place and place of relay, it is possible to use semiconductor devices or other devices equivalent.
