1. A device configured to control pressure relief of a weapon, the device comprising: a detonator housing connectable with a casing of the weapon;an explosive charge disposed in the detonator housing;a combined ignition device having a first ignition location for detonative initiation and a second ignition location for deflagrative initiation of the explosive charge, wherein the device is configured to be triggered before or simultaneously with the initiation of the deflagrative reaction of the explosive charge; andat least one channel disposed in or directly adjacent to the combined ignition device, wherein the at least one channel is configured to be opened in a controlled manner, and wherein the at least one channel connects an interior of the weapon, via the casing of the weapon, with external surroundings of the weapon such that pressure relief at the second ignition location is provided during deflagration. 2. The device according to claim 1, wherein the at least one channel has a minimum cross-section that depends on a diameter of the explosive charge, which minimum cross-section increases regressively with an increasing charge diameter and progressively with intensifying initiation. 3. The device according to claim 2, wherein a cross-sectional surface area of the at least one channel is at least 7 mm2, and, as a function of the diameter of the explosive charge, is between 1/1000 and 1/50 of a cross-sectional surface area of the explosive charge. 4. The device according to at least one of claim 2, wherein the least one channel that can be opened using a drive. 5. The device according to claim 4, wherein a point in time at which the least one channel is opened is freely selectable between arming of the ignition device and deflagrative initiation. 6. The device according to at least one of claim 2, wherein the least one channel can be opened in the controlled manner as a function of reaching a selectable acceleration in a direction of a main axis of the weapon. 7. The device according to claim 1, wherein a cross-sectional surface area of the at least one channel is at least 7 mm2, and, as a function of a diameter of the explosive charge, is between 1/1000 and 1/50 of a cross-sectional surface area of the explosive charge. 8. The device according to at least one of claim 7, wherein the least one channel that can be opened using a drive. 9. The device according to claim 8, wherein a point in time at which the least one channel is opened is freely selectable between arming of the ignition device and deflagrative initiation. 10. The device according to at least one of claim 7, wherein the least one channel can be opened in the controlled manner as a function of reaching a selectable acceleration in a direction of a main axis of the weapon. 11. The device according to claim 1, wherein the least one channel can be opened in the controlled manner as a function of time or can be permanently open at certain times. 12. The device according to at least one of claim 1, wherein the least one channel that can be opened using a drive. 13. The device according to claim 12, wherein a point in time at which the least one channel is opened is freely selectable between arming of the ignition device and deflagrative initiation. 14. The device according to at least one of claim 13, wherein the least one channel can be opened in the controlled manner as a function of reaching a selectable acceleration in a direction of a main axis of the weapon. 15. The device according to at least one of claim 12, wherein the least one channel can be opened in the controlled manner as a function of reaching a selectable acceleration in a direction of a main axis of the weapon. 16. The device according to at least one of claim 1, wherein the least one channel can be opened in the controlled manner as a function of reaching a selectable acceleration in a direction of a main axis of the weapon. 17. The device according to claim 1, wherein the least one channel can be opened in the controlled manner by at least one gas generator. 18. The device according to claim 1, wherein the at least one channel can be opened in the controlled manner using planned breaking points that have been worked in, at a previously-defined minimum pressure.
