Abstract
The utility model provides a multipath continuous heavy current pulse output control circuit comprising at least two heavy current pulse output control circuits. Each heavy current pulse output control circuit comprises ignition tubes, a first transient inhibition diode, a second transient inhibition diode, a solid state relay, a first electromagnetic relay and a second electromagnetic relay. A front part circuit is controlled via software, and the second electromagnetic relay, the first electromagnetic relay and the solid state relay are closed in order through control so that other ignition tubes are not powered on simultaneously when one of the ignition tubes is powered on, and thus personal safety is guaranteed and the service life of equipment is prolonged. Meanwhile, the circuit is easy to carry out so that equipment cost can be effectively reduced and an excellent solution scheme is provided for other equipment with functions of the multipath continuous heavy current pulse output control circuit.
Description
Technical field
The utility model belongs to integration test field.
Background technology
Multichannel igniting radiation pattern is part important in armament systems, because multichannel firing circuit accesses same power supply simultaneously, and multichannel firing circuit is considered the factors such as cost and volume when design, possible multichannel firing circuit shares a relay, if certain relay breaks down, there will be multichannel firing circuit to switch on simultaneously, a plurality of weapons are lighted a fire simultaneously, likely cause the loss of personnel and equipment.
Utility model content
The technical problem that the utility model solves is: overcome the deficiencies in the prior art, provide a kind of multichannel continuous heavy current pulse output control circuit, guarantee that multiple rocket projectile is sequentially fired, simultaneously multiple rocket projectile ignition failure simultaneously does not occur, guarantee that equipment is repeatedly used simultaneously.
The technical solution of the utility model is: the continuous heavy current pulse output control circuit of a kind of multichannel, comprise at least two heavy current pulse output control circuits, wherein each heavy current pulse output control circuit comprises ignitron, the first Transient Suppression Diode, the second Transient Suppression Diode, solid state relay, the first electromagnetic relay, the second electromagnetic relay; The second described electromagnetic relay is binary channel electromagnetic relay; The normally opened contact common port of solid state relay is connected to the negative terminal of the first Transient Suppression Diode; The first transient state suppresses the positive ending grounding of diode; The normally opened contact of solid state relay is connected to the normally opened contact common port of the first electromagnetic relay; The normally opened contact of the first electromagnetic relay is connected to the first via normally opened contact common port of the second electromagnetic relay and the negative terminal of the second Transient Suppression Diode simultaneously; The positive ending grounding of the second Transient Suppression Diode; The first via normally opened contact of the second electromagnetic relay is connected to one end of ignitron and the second road normally-closed contact common port of the second electromagnetic relay simultaneously; The second road normally-closed contact of the second electromagnetic relay is connected to the other end and the ground of ignitron simultaneously; The normally opened contact common port of the solid state relay of each heavy current pulse output control circuit is all connected to power supply.
The utility model advantage is compared with prior art:
The utility model circuit is implemented simple, and multichannel firing circuit can share a small amount of relay, to reduce equipment cost and equipment failure rate and maintenance cost; If circuit safety improves ，You, No. tri-relays guarantee there is electric current in advance by not making ignitron ignite, assurance personnel and device security; Software control is simple, controls software code quantity few, reduces development difficulty, improves equipment functional reliability.
Accompanying drawing explanation
Fig. 1 is single channel heavy current pulse output circuit.
Embodiment
The continuous heavy current pulse output control circuit of a kind of multichannel of the utility model, comprise at least two heavy current pulse output control circuits, wherein each heavy current pulse output control circuit comprises ignitron, the first Transient Suppression Diode, the second Transient Suppression Diode, solid state relay, the first electromagnetic relay, the second electromagnetic relay; The second described electromagnetic relay is binary channel electromagnetic relay; The normally opened contact common port of solid state relay is connected to the negative terminal of the first Transient Suppression Diode; The first transient state suppresses the positive ending grounding of diode; The normally opened contact of solid state relay is connected to the normally opened contact common port of the first electromagnetic relay; The normally opened contact of the first electromagnetic relay is connected to the first via normally opened contact common port of the second electromagnetic relay and the negative terminal of the second Transient Suppression Diode simultaneously; The positive ending grounding of the second Transient Suppression Diode; The first via normally opened contact of the second electromagnetic relay is connected to one end of ignitron and the second road normally-closed contact common port of the second electromagnetic relay simultaneously; The second road normally-closed contact of the second electromagnetic relay is connected to the other end and the ground of ignitron simultaneously; The normally opened contact common port of the solid state relay of each heavy current pulse output control circuit is all connected to power supply.
This circuit is software control interlock circuit, and software is conciliate guarantor's relay by three tunnels " multiplex decoder " processes " drive circuit " to solid state relay, electromagnetic relay and carried out substep control.
As shown in Figure 1, the first electromagnetic relay, the second electromagnetic relay and solid state relay need to be connected to " ignitron " energising.
When system is not switched on, the second relay disconnects " ignitron " and firing circuit, simultaneously by " ignitron " short circuit, guarantees Initiator Safety.After system energising, general+V energising, firing circuit is ready to.First by software, the second electromagnetic relay is controlled, " ignitron " short-circuit protection disconnects, access point ignition circuit; Then software control the first electromagnetic relay is connected, and this action can prevent that large electric current from damaging circuit after producing spark, and secondary solution has been protected; Last software control solid state relay is connected, firing circuit path, " ignitron " energising.Although meanwhile subsequent point ignition circuit+V is charged, but due to the not action of the first electromagnetic relay, the second electromagnetic relay and solid state relay, other " ignitrons " can not switch on, if any one relay breaks down, igniting can, by other roads " ignitron " energising, can not carried out ignition function to multichannel " ignitron " simultaneously simultaneously.
The content not being described in detail in the utility model specification belongs to professional and technical personnel in the field's known technology.
