The invention relates to a method and a device for controlling the power supply of at least one aircraft maintenance actuator (7) from an electrical power supply network (10) of the aircraft comprising means (14) for controlling the electrical power supply of at least one maintenance actuator, and means (15) for establishing communication between the control means and at least one control unit (16) allowing a user to control the operation of at least one actuator. The control means are designed to compare the state of at least one control unit with at least one reference state (SBR) and/or an abnormal state (SBE1, SBE2, SBE3) for switching-on purposes, and to prohibit the activation of the actuator if the state of the control unit is different from a reference state (SBR) or corresponds.

1. A device for controlling power supply of at least one aircraft maintenance actuator from an electrical power supply network of the aircraft, comprising: control means for controlling the electrical power supply of at least one maintenance actuator andmeans for establishing communication between the control means and at least one control unit allowing a user to control the operation of the at least one maintenance actuator,wherein the at least one control unit comprises a first control button which when it is depressed, corresponds to the sending of a command to move the maintenance actuator in a direction causing the opening of a cowling, and a second button which when it is depressed, corresponds to the sending of a command to move the maintenance actuator in a direction causing the closing of the cowling, the control means being arranged to compare states of the first and second control buttons, with:a reference state in which the first control button and the second control button are in its rest position and for which powering up of the actuator can be authorized by the control means when the power supply network is powered up,a first abnormal state in which the first control button is depressed and the second control button is in its rest position, for which the powering up of the actuator is blocked when the power supply network is powered up,a second abnormal state in which the first control button is in its rest position and the second control button is depressed, for which the powering up of the actuator is blocked when the power supply network is powered up, anda third abnormal state in which the first control button is depressed and the second control button is depressed, for which the powering up of the actuator is blocked when the power supply network is powered up. 2. The device as claimed in claim 1, wherein the control means are designed to authorize activation of the actuator when the state of the control unit is modified to return to the reference state for powering up. 3. The device as claimed in claim 1, wherein the reference state or states correspond to states of the control unit in which no movement of the actuator is ordered. 4. A turbojet engine nacelle of an aircraft comprising at least one maintenance actuator, a control unit and a device as claimed in claim 1. 5. The nacelle as claimed in claim 4, wherein the device is arranged in a unit for powering and monitoring the actuators. 6. The nacelle as claimed in claim 4, wherein the device is arranged on the actuator. 7. A method of controlling a power supply of at least one aircraft maintenance actuator from an electrical power supply network of the aircraft comprising, a step of receiving an electrical signal from a control unit comprising a first button and a second button;a step of deciding whether a state of the control unit is a reference state or abnormal states by comparing states of the first and second buttons of the control unit with; a reference state, in which the first control button and the second control button are in its rest position,a first abnormal state in which the first control button is depressed and the second control button is in its rest position,a second abnormal state in which the first control button is in its rest position and the second control button is depressed,a third abnormal state in which the first control button is depressed and the second control button is depressed; anda step of powering up of the at least one maintenance actuator according to an authorization of a control means if the control unit is in the reference state. 8. The method as claimed in claim 7, wherein the activation of the actuator is authorized when the state of the control unit is modified to return to the reference state for power-up. 9. The method as claimed in claim 7, wherein the reference state or states correspond to states of the unit in which no movement of the actuator is ordered.
