Description
Technical field
The invention belongs to test control technology field, be specifically related to a kind of priming system short-circuit protection circuit that is used for measuring and controlling equipment.
Background technology
All kinds of priming systems constitute a kind of huge danger behind the dress arrow, in case accident occurs, gently then cause the damage accident, and heavy then arrow is ruined the people and died, and consequence is hardly imaginable.Therefore, behind priming system dress arrow, before the transition emission, must adopt certain mode to make priming system be in the short-circuit protection state.
According to the information of having announced, the method for security protection of priming system is mainly the short-circuit protection method at present.In the technical literature " control detection reliability " that the Yuhang Publishing House announces; adopted a kind of short circuit plug Protection Code, behind priming system dress arrow, the disconnection cable system is connected with electric detonator; short circuit plug is docked with priming system, make it before the transition emission, be in the short-circuit protection state always.In the technical literature " control detection reliability " that the Yuhang Publishing House announces, also adopted a kind of relay contact Protection Code, promptly behind priming system dress arrow, the relay normally closed contact that carries equipment with arrow provides short-circuit protection to priming system.
Though more than two kinds of methods through the model evidence certain feasibility, have following problem:
(1) need there be certain operational risk in short circuit plug to hand disassembly before the arrow or butt joint.If the manually-operated error successfully buries unfavorable hidden danger or fortuitous event occurs for follow-up joint-trial test or flight test.
(2) the relay contact Protection Code is unfavorable for that arrow carries the device miniaturization design.Consider the size of the priming system initial firing current that relay contact can bear, the general volume of selected relay is big, quantity is more.If for the multichannel priming system provides safeguard protection, consider Redundancy Design again, the volume of relevant device will be bigger.
Therefore, need further investigation to adapt to the Initiator Safety protection scheme of following observation and control technology development.
Summary of the invention
The objective of the invention is: overcome above shortcoming; provide a kind of can safely, quickly and reliably realize priming system from the safeguard protection state to conversion of operation state; and the circuit that can monitor the state exchange result; use it in the measuring and controlling equipment; can guarantee the security after arrow carries priming system dress arrow, can provide measurement/igniting path control for priming system again.
