Description

Technical Field

[0001] The invention belongs to the field of detection technology, and in particular relates to a safe static electrical detection method for missile products. Background Art

[0002] Static electrical testing of missile products is an important part of the trial production process. Static parameter testing is performed on missile products before they leave the factory to determine whether their electrical performance is normal. At present, the traditional testing method for static parameters is to use an adapter cable to connect to the missile body test port for testing. Traditional testing methods: 1) Unplug the missile body short-circuit plug; 2) Plug in the adapter cable and use the MF500 multimeter and M210 low resistance meter to test the resistance; 3) Unplug the connectors at both ends of the adapter cable and plug the missile body short-circuit plug into the missile body test port. In the inspection process, the pyrotechnic channel and the non-pyrotechnic channel were not distinguished, and the importance of pyrotechnic channel testing was not taken seriously. On the other hand, during the test, it is impossible to short-circuit the pyrotechnic channel immediately after the pyrotechnic channel test is completed. The pyrotechnic products on the missile are in an open circuit state during the entire inspection process. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a safe static electrical detection method for missile and rocket products. The product test cable is connected by a cable, and the pyrotechnic port is first tested and qualified, and then a short-circuit plug is inserted to perform non-pyrotechnic port testing, thereby achieving the shortest time for the ignition port to be open-circuited during the static detection process. The detection method meets safety standards, is simple and practical in the static detection of missile and rocket products, and has broad application prospects and promotion value. The outstanding advantages of the present invention are: it greatly improves the safety of static electrical detection, sorts the detection priority, and avoids the pyrotechnic port of the projectile being in an open-circuit state when the static detection is abnormal.

[0004] The technical solution adopted by the present invention to solve the technical problem is as follows:

[0005] Step 1: Place the missile product in the explosion-proof room, with the warhead facing the window and the missile body reliably grounded;

[0006] Step 2: Select the test cable of the corresponding product, unplug the short-circuit head of the projectile detection port, plug the A end of the test cable into the detection port, and plug the B end of the test cable into the B end of the cabin wall-penetrating adapter cable;

[0007] Step 3: The tester connects the A end of the through-the-wall adapter cable to the test equipment in the test operation room;

[0008] Step 4: Use the M210 low resistance meter to test the resistance of the pyrotechnic port on the missile;

[0009] Step 5: After the resistance value is tested and qualified, the personnel enter the explosion-proof room and connect the C end of the test cable with the short-circuit plug of the projectile;

[0010] Step 6: The tester conducts non-fire port resistance test in the test room;

[0011] Step 7: After the test is completed, enter the explosion-proof room, unplug the test cable at the projectile detection port, and plug the projectile short-circuit connector at the C end of the test cable into the projectile detection port.

[0012] Furthermore, in step 2, when selecting the test cable, it is necessary to select a test cable that matches the product to be tested, wherein the passage between the A-end connector and the C-end connector of the test cable is a pyrotechnic channel and the length is not more than 150 mm, and the C-end connector is the same model as the connector of the projectile detection port, which is used to short-circuit the projectile pyrotechnics; the channel between the A-end connector and the B-end connector of the test cable is all the channels of the detection port.

[0013] Furthermore, in step 6, the resistance of the non-pyrotechnic port is tested using an MF500 multimeter and an M210 low resistance meter.

[0014] The beneficial effects of the present invention are as follows:

[0015] Compared with the existing methods, the method of the present invention combines the adapter cable with the test cable, first performs pyrotechnic resistance detection and then performs non-pyrotechnic resistance detection, wherein the test cable leads out the pyrotechnic channel (connector C end) separately and connects with the projectile short-circuit head to reduce the open circuit time of the pyrotechnic on the projectile. The connector at the C end of the test cable is the same model as the connector at the projectile detection port, and the projectile short-circuit head can be reused. The method is simple and practical, and can ensure the safety of static electrical detection of projectile products. BRIEF DESCRIPTION OF THE DRAWINGS
