Definitions

  • the invention relates to a device for increasing the safety in the operation and firing a machine gun on a weapons system.
  • EP 0 071 734 A describes such a device and forms a basis for the unconditional claim 1.
  • it is an armored and armed vehicle, which consists of the usual parts such as drive motor, gears, wheelsets or crawler, a crew room and a housing , which houses all inputs and attachments, and a weapons system composed, with MK and MG weapons systems basically have electromechanical Abfeuer Vietnamesee.
  • the invention may also refer to ship porters and MKW on helicopters, aircraft and fort guns.
  • the firing of MK or MG takes place in a known vehicle via a relay-controlled firing circuit.
  • Part of this firing range are the signals of the limit switch firing lug, clamping cylinder front, MK or MG selected, MK or MG safe, ammunition available and shooting range setting.
  • MK the signal position of the ammunition feeder acts on the firing circle.
  • the disadvantage of the existing solutions lies in the fact that the control of the firing magnet of the machine gun via a high-current relay, the so-called firing relay occurs.
  • the firing relay occurs.
  • a failure of the firing relay or the upstream safety circuit can lead to an unwanted firing. Examples of known faults are sticking of the relay contacts or sticking of the firing button.
  • the object of the invention is to increase the safety of electrical Aberieungs wornen in machine guns by inserting another switching element in the firing circuit and by building a second, independent and programmable safety circuit parallel to the discretely wired safety circuit of the existing firing device.
  • the existing device and technology is preferably not replaced, but it should be expanded to a dual safety circuit.
  • a second switching element is used directly in the branch of the firing magnet, which is controlled and switched parallel to the existing, relay-controlled firing circuit by a second, independent control and monitoring logic.
  • a firing relay as a second switching element and a semiconductor switch can be used.
  • the advantages of the invention are that the failure of a firing relay as a component no longer leads directly to an unwanted firing. Since a second supervisory circuit that provides dual security is built in, failures in one of two existing paths no longer result in a security-critical weapon condition.
  • a firing module 1 contains the blocks: semiconductor switch 3, voltage monitor 5, voltage converter 10, program-controlled logic and evaluation circuit 11, control 12, display 13, input module 14 and bus driver 15.
  • the circuit is supplied with vehicle network voltage at terminal 16.
  • the programmable circuit 11 can be loaded and maintained with programs.
  • the information interface 8 further higher-level controllers and computers can be connected.
  • the existing firing safety circuit 6 with various contacts 17, representing, for example, the signals “weapon on” and “weapon unlocked” and more, as well as the firing button 9 and the firing relay 2 is shown.
  • a firing by means of the button 9 and with effect on the firing magnet 4 is only possible if all contacts 17 are closed, the emergency stop switch 19 is not triggered, the relay 2 is tightened including the contact 2a and the semiconductor switch 3 is turned on ,
  • the limit switch signals 17 of the safety devices relevant for the firing act not only on the conventional relay safety circuit 6 and thus on the firing relay 2, but are also connected to the opto-decoupled inputs 18 of the firing module 1.
  • a program-controlled logic 11 in the firing module 1 processes and combines the security signals 17, 18 independently of the existing relay circuit 6 and controls a power 12 to a power semiconductor switch 3, which switches the negative terminal of the firing magnet 4 to ground.
  • the positive terminal of the firing magnet 4 is switched by the firing relay 2, 2 a and the emergency stop switch 19.
  • the control 12 of the circuit breaker 3 receives positive supply potential and can be turned on by the program-controlled logic 11.
  • the logic 11 must unlock the drive 12 by means of a signal and also drive through explicitly by means of a second signal.
  • the two drive signals of the logic 11 must also have different logic levels.
  • the firing module 1 can also switch an additional relay 20 of the existing relay circuit 6 in order to likewise block or release the firing relay 2 of the existing safety circuit 6.
  • the firing module 1 contains a programming 7 and an information interface 8, for example a CAN bus interface.
