Description

Technical Field

[0001] The invention belongs to the technical field of calibration and testing of geomagnetic navigation devices, and in particular relates to a test system for automatic calibration and performance verification of geomagnetic components. Background Art

[0002] The geomagnetic component is an autonomous navigation device that uses magnetic sensors to sense the geomagnetic field signal and outputs the carrier's attitude angle and angular velocity. It is widely used in important navigation fields, especially in the defense field, due to its low cost and small size. Therefore, it is particularly important to calibrate and verify the performance of the geomagnetic component reliably, accurately and quickly.

[0003] In the traditional geomagnetic component calibration and performance verification process, the calibration and performance verification processes are separated and work is divided into two processes. During the working process, parameter calculation, performance evaluation, report generation and other functions are all completed offline, and generally only one set of products can be calibrated and tested at a time. The testing process is cumbersome, human errors occur from time to time, and the efficiency is low. It consumes a lot of manpower and material resources, cannot meet the needs of mass production, and seriously affects efficiency and output value. For the above problems, in the relevant domestic and foreign literature, there are no effective ideas and methods for the mass production and testing of geomagnetic components in tactical weapons.

[0078] Example 1

[0079] In order to solve the above technical problems, the present invention provides a test system for automatic calibration and performance verification of geomagnetic components, which is completed by the following technical solutions.

[0080] 1. Block diagram of this system. Figure 1 As shown: a non-magnetic turntable (1), a programmable power supply (2), a data acquisition and communication unit (3), a host computer (4) and a human-computer interaction interface (5).

[0081] 2. Implementation principle of this system:

[0082] This system makes full use of the DUT's ability to download parameters through the serial port, and combines the DUT calibration and DUT performance verification processes into one.

[0083] The DUT is installed on the calibration fixture and connected to the connector above the non-magnetic turntable through the matching cable. The control module in the host computer sends power-on / off instructions to the programmable power supply through the data acquisition and communication unit according to the process, sends start, binding and other instructions to the DUT, sends zeroing, position / speed operation and other instructions to the turntable, and receives the turntable status information and the output response and navigation information of the DUT through the data acquisition and communication unit. The data storage module in the host computer parses the received navigation information of the DUT according to the protocol and stores it in the corresponding position of the host computer for use by the calibration module and performance verification module. After the entire calibration and test are completed, the test results are automatically generated, and the product is clearly displayed in the report based on the product indicators to determine whether it is qualified.

[0084] During the operation of the system, the control module and data storage module in the host computer need special treatment. Since the content and process of the response commands of various geomagnetic component products are different, the process control part of the control module in the host computer needs to be modified according to the specific state of the device under test. Since the output navigation information formats of various geomagnetic component products are different, the data parsing code in the data storage module in the host computer needs to be modified according to the specific output format of the device under test.

[0085] The human-computer interaction interface can display the test phase, power status, turntable status, calibration parameters and test results in real time. The information that needs to be manually entered or selected includes product type and number, and connection serial port. During the test, all editable input information columns will be grayed out to avoid misoperation.

[0086] Example 2

[0087] This embodiment specifically describes a test system that integrates calibration and performance testing functions of a dual-axis geomagnetic measurement component proposed by the present invention to complete the calibration and testing of the geomagnetic component.

[0088] like Figure 2 As shown, the steps for implementing the fully automatic calibration and performance test of the geomagnetic component are as follows:

[0089] Step 1: Install 8 sets of geomagnetic components on the calibration fixture, and then fix them on the non-magnetic turntable. Connect the special measurement cables of the 8 sets of geomagnetic components to the conductive slip ring terminals on the turntable. The conductive slip ring terminals under the turntable are connected to the turntable measurement and control system and program-controlled power supply through matching cables, and the non-magnetic turntable is powered on.

[0090] Step 2: Open the host computer and the human-computer interaction interface, fill in the product information, data storage path, voltage, serial port and other information in the human-computer interaction interface according to the input parameters, click the start test button, and the test system starts working;

[0091] Step 3: The control module in the host computer automatically sends the zero-seeking instruction to the non-magnetic turntable through the data acquisition and communication unit to complete the turntable zero-seeking;

[0092] Step 4: After the turntable has completed zeroing, the host computer powers on the DUT according to the process control, and sends instructions to the non-magnetic turntable to make the turntable run according to the state required by the calibration process. At the same time, the output information of the DUT is collected through the data acquisition and communication unit and the data storage module in the host computer, and transferred to the specified path folder;

[0093] Step 5: After the calibration data acquisition and storage state is completed, the calibration module in the host computer is used to calculate, store and download the calibration parameters to the device under test, and the control module in the host computer cuts off the power to the device under test;

[0094] Step 6: The host computer powers on the DUT for the second time according to the process control, and sends instructions to the non-magnetic turntable to make the turntable run according to the state required by the performance verification process. At the same time, the output information of the DUT is collected through the data acquisition and communication unit and the data storage module in the host computer, and transferred to the specified path folder;

[0095] Step 7: After the performance verification data collection and storage state is completed, the performance verification module in the host computer calculates the attitude angle and angular rate accuracy, automatically generates a report and transfers it to the specified path folder;

[0096] Step 8: The non-magnetic turntable (1) is powered off and the test is completed.

[0097] The test pieces in this embodiment are eight sets of geomagnetic components, but in actual applications the data acquisition and communication units can be expanded and are not limited to eight sets of geomagnetic components.

[0098] In summary, the present invention belongs to the field of calibration and testing technology of geomagnetic navigation devices, and specifically relates to a test system for automatic calibration and performance verification of geomagnetic components. In order to save time for calibration and testing, save labor costs, and realize the batch demand for production and testing, the present invention provides a test system with integrated calibration and performance verification functions. The system solves the problems of low efficiency in power supply, test methods, and test report generation for geomagnetic component testing, and realizes the automated processing of calibration and performance verification of geomagnetic components. The test system provided by the present invention comprises: a non-magnetic turntable, a programmable power supply, a data acquisition and communication unit, a host computer, and a human-computer interaction interface.

[0099] The test system can complete the calibration and performance verification of multiple geomagnetic components at the same time, allowing the turntable to run according to the pre-set program, and complete the power-on and power-off of the geomagnetic components, data collection and storage, calibration parameter calculation and download, performance evaluation and report generation according to the test process, so as to achieve no human intervention in the whole process, avoid misoperation, and improve reliability. After using this system, during the calibration and performance verification of the geomagnetic components, after setting the parameters, the user only needs to click the test start button and wait for the test report to be generated to complete the test process. The fully automatic calibration and performance verification process reduces the labor intensity of personnel, saves time and resources, and effectively improves the efficiency of geomagnetic component calibration and performance verification.

[0100] The working object of this test system is the geomagnetic component, which needs to have the function of downloading parameters through the serial interface, so as to realize the automation process of the whole process of geomagnetic component calibration and performance verification.

[0101] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
