Abstract

The testing apparatus of the present invention provides a self-contained test module that connects to the weapons firing circuit on the weapons platform. This test module communicates with a data collector and controller that is carried by a technician or operator. The communication link between the test module and the data collector and controller is wireless so that the technician can move about without interference from the cable. The test module, which contains a digital voltage detector, is more accurate than prior analog voltage detectors. The test module connects to different connectors, allowing for a reduction of equipment needed in the testing apparatus and providing a significant savings in weight. The data collector and controller stores test data of a particular circuit over a period of time and performs analysis on that test data to identify upcoming or potential problems so that repair can be made before operational readiness is compromised by a circuit failure.

Claims

1. A light weight portable system for multi-testing of an armament circuit, comprising:

at least one connector, the connector structured and arranged to electrically connect to the armament circuit;

a test module coupled to the connector, the test module comprising a testing circuit, the testing circuit testing the armament circuit when the connector is connected to the armament circuit on a first end and connected to the testing circuit on a second end, the testing module comprising a controller and a first communications circuit;

a data collector and controller comprising a second communications circuit, the first and second communications circuits communicating over a wireless link, the data collector and controller sending test instructions to the test module over the link and the test module sending test data from the armament circuit over the link to the data collector and controller; and

wherein, the data collector and controller is a portable handheld device.

2. The apparatus of claim 1 wherein the testing module comprises at least two testing circuits, wherein the at least two testing circuits comprise a first digital testing circuit that tests for stray voltages and a second testing circuit that tests for sufficient firing current.

3. The apparatus of claim 2 wherein:

the data collector and controller sends test instructions over the wireless link for selection of one of the at least two testing circuits, the testing circuit that tests for sufficient firing current.

4. The apparatus of claim 3 wherein the data collector and controller prompts a technician to exercise the armament circuit during the operation of the testing circuit.

5. The apparatus of claim 1 wherein the testing module comprises a circuit that tests for continuity of the armament circuit and a circuit that tests for stray voltage.

6. The apparatus of claim 1, further comprising:

at least two connectors, with each connector having a different first end that connects to a different armament circuit and a same second end that connects to the test module.

7. The apparatus of claim 1 wherein the data collector and controller determines if the armament circuit passes or fails the testing by comparing the test data to stored testing values.

8. The apparatus of claim 1 wherein the data collector and controller determines trending of the armament circuit by comparing the test data to historical test data for the same armament circuit and if the test results are within a predetermined range of test results provides prompts to a technician to take corrective action.

9. A method of testing an armament circuit, comprising the steps of:

providing a connector that can electrically couple to the armament circuit and coupling a first end of the connector to the armament circuit;

connecting a test module to a second end of the connector;

establishing a wireless communications link between the test module and a handheld data collector and controller;

climbing into a cockpit associated with the armament circuit and bringing the handheld data collector and controller into the cockpit;

receiving instructions from a display on the handheld data collector and controller and exercising the armament circuit from within the cockpit, accordingly;

sending an instruction from the handheld data collector and controller over the link to the test module to test the armament circuit;

testing the armament circuit with the test module;

providing results of the test to the data collector and controller over the link.

10. The method of claim 9, wherein the step of testing the armament circuit further comprises the step of de-energizing the armament circuit and testing for stray voltages.

11. The method of claim 9, wherein the step of testing the armament circuit further comprises the step of testing for the presence of voltage.

12. The method of claim 9, wherein the step of testing the armament circuit further comprises the step of testing for sufficient firing current.

13. The method of claim 9, wherein the step of testing the armament circuit further comprises the step of de-energizing the armament circuit and testing for continuity of the armament circuit.

14. The method of claim 9, further comprising the step of determining trending of the armament circuit by comparing the test data to historical test data from the same armament circuit and if the test results are within a predetermined range of test results then providing a prompt to a technician to take corrective action.

15. The method of claim 9, further comprising:

testing a continuity across the connector between the testing module and the armament circuit.
