The complete round test safety control circuit designs a safety control circuit in testing devices, ensures the safety of a complete round test by introducing the safety control signals and is capable of effectively avoiding server consequences such as accidental activation of the initiating explosive device and the like caused by mis-operation.
Description
Technical field
The utility model relates to test of missile control field, is specifically related to a kind of complete round test safety control circuit.
Background technology
In the past in the test process of guided missile, safety for support personnel and equipment, priming system can not be installed on the bullet during test (comprise battery, fuse, warhead, boost motor, fuel oil and various electric detonators etc.), guided missile and priming system are paid army respectively, the installation of priming system all is to finish at army's technical area test of missile, can increase the operation easier of army so on the one hand, increase missilery time, on the other hand owing to need carry out dismounting when priming system is installed, may cause the guided missile of test passes to break down once more and can't be detected the missile bay section.For improving the quick-reaction capability of combat troop, it is convenient, fast to guarantee that army uses, and improves army and safeguards service efficiency, and certain model guided missile has adopted the complete round measuring technology, be that guided missile also will dispatch from the factory and pays with the complete round state, guided missile maintenance is in the future also carried out under the complete round state.To this type guided missile, comprised 11 electric detonators, 1 battery, 1 warhead, 1 cover fuse, 1 boost motor in the complete round, above-mentioned any one priming system is the unexpected extremely serious consequence such as all can set off an explosion that activates in test process.Therefore must study corresponding method, guarantee the security when guided missile is tested under the complete round state.
Summary of the invention
The purpose of this utility model is to provide a kind of complete round test safety control circuit that can effectively guarantee the complete round test safety.
Realize the technical scheme of the utility model purpose: a kind of complete round test safety control circuit, comprise dpdt relay K2, the moving point of relay K 2 connects security control signal and priming system ignition signal respectively, a normal battle of relay K 2 connects test circuit, normally closed point connects priming system, the normal battle of another of relay K 2 connects the input of photoelectrical coupler A1, the output of photoelectrical coupler A1 connects contactor K1, the input of photoelectrical coupler A1 connects dc source and security control signal by current-limiting resistance R1, the moving point of contactor K1 connects power supply circuits on the bullet, and normal the battle connects the ground dc source.
Aforesaid a kind of complete round test safety control circuit, photoelectrical coupler A1 adopts the MC1416P model.
Effect of the present utility model is: design safety control circuit in testing equipment, and by introducing the security that the security control signal has guaranteed the complete round test, the serious consequences such as the unexpected activation of priming system that can effectively avoid maloperation to cause.
Description of drawings
Fig. 1 is a kind of complete round test safety control circuit figure provided by the utility model;
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, a kind of complete round test safety control circuit of the present utility model, comprise dpdt relay K2, the moving point of relay K 2 connects the security control signal respectively, the priming system ignition signal, a normal battle of relay K 2 connects test circuit, normally closed point connects priming system, the normal battle of another of relay K 2 connects the input of photoelectrical coupler A1, the output of photoelectrical coupler A1 connects contactor K1, the input of photoelectrical coupler A1 is current-limiting resistance R1 connection 28.5V dc source and the security control signal of 3K by resistance, the moving point of contactor K1 connects power supply circuits on the bullet, and normal the battle connects 28.5V ground dc source.Photoelectrical coupler A1 selects the MC1416P model for use.
The operation principle of complete round test safety control circuit is as follows:
" security control signal " and " priming system ignition signal " be the input of cut-in relay K2 simultaneously, after sending the security control signal, and the adhesive of K2 relay, priming system disconnects on " priming system ignition signal " and the bullet, inserts test circuit and detects; " security control signal " simultaneously, promptly " " signal inserts the input of photoelectrical coupler A1, control is to the contactor K1 of guided missile power supply.During test, send the security control signal, the adhesive of K2 relay, then " " signal enters testing equipment, this moment, contactor K1 can be according to closed to guided missile power supply instruction or disconnect, and realizes normally power supply and outage to guided missile.If do not send the security control signal, perhaps the K2 relay breaks down, normally adhesive, then because of do not come seeder " " signal, K1 can't normally closed, testing equipment can not be powered to guided missile, has guaranteed the security of test.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.If these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
