Definitions

  • the invention relates to an armored and armed vehicle that consists of the usual parts such as drive motor, gears, wheelsets or chain drive, one Crew room and a housing that accommodates all internals and attachments, and one Weapon system composed, whereby MK and MG weapon systems in principle have electromechanical firing circuits.
  • the invention can also relate to Ship guns and MKW on helicopters, airplanes and production guns Respectively.
  • the firing of MK or MG takes place in a known vehicle via a relay controlled firing circuit.
  • Part of this firing circuit are the signals of the Limit switch firing pawl, clamping cylinder in front, MK or MG selected, MK or MG safe, ammunition and shooting range setting.
  • the MK also works the signal position of the ammunition feeder on the firing circuit.
  • the disadvantage of the existing solutions is mainly that the control of the Firing magnets of the machine gun via a high-current relay, the so-called Firing relay takes place.
  • the so-called Firing relay takes place.
  • high quality components with increased Reliability can occur in the event of a defect in the firing relay or the upstream one Security circuit come to an unwanted shot.
  • Examples for Known errors are sticking of the relay contacts or sticking of the fire button.
  • the object of the invention is to ensure the safety of electrical firing devices for machine guns by inserting another switching element in the firing circuit as well as by building a second, independent and program-controlled Safety circuit parallel to the discretely wired safety circuit of the existing one Increase firing device.
  • the existing equipment and technology is included preferably not replaced, but should be a double safety circuit be expanded.
  • a second switching element is located directly in the branch of the firing magnet used by a second, independent control and monitoring logic controlled and switched in parallel to the existing, relay-controlled firing circuit becomes.
  • the defect of a circuit or a fire relay no longer leads to this unwanted firing.
  • a semiconductor switch can also 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 shot. Since a second Monitoring circuit, which creates a double security, is installed, lead to errors in one of two existing paths no longer becomes a safety-critical one Weapons state.
  • a firing module 1 contains the blocks: semiconductor switch 3, Voltage monitoring 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 mains voltage at connection 16.
  • a Programming interface 7 the programmable circuit 11 with programs be loaded and maintained.
  • the information interface 8 more higher-level controls and computers can be connected.
  • the existing fire safety circuit 6 with various contacts 17, for example the Signals "weapon on” and “weapon unlocked” and others represent, as well as the Fire button 9 and the fire relay 2 shown.
  • Firing using button 9 and with effect on the firing magnet 4 is only possible if all contacts 17th are closed, the emergency stop switch 19 is not triggered, the relay 2 is energized including the contact 2a and the semiconductor switch 3 is turned on.
  • the Limit switch signals 17 of the safety devices relevant for firing act not only on the conventional relay safety circuit 6 and thus on the fire relay 2, but are also connected to the opto-decoupled inputs 18 of the firing module 1 connected.
  • a program-controlled logic 11 in the firing module 1 processes and links the safety signals 17, 18 independently of the existing relay circuit 6 and controls via a control 12 a power semiconductor switch 3, the Minus connection of the firing magnet 4 switches to ground.
  • the plus connection of the Firing magnet 4 is from the firing relay 2, 2a and the emergency stop switch 19 connected.
  • the presence of the supply voltage on the firing magnet 4 or on Semiconductor switch 3 is monitored by the firing module 1 to detect errors within the electrical fire device to detect.
  • the semiconductor switch 3 is preferably a version with internal monitoring is used.
  • a programming 7 and an information interface 8 for example a CAN bus interface.
