Detailed Description

As shown in fig. 1, the adapter box for calibrating the angle signal of the attitude and heading equipment comprises a box body 1, wherein the upper surface of the box body 1 is an operating panel 2, an adapter jack 4 for connecting with a metering standard instrument is arranged on the operating panel, a cross-linking interface 5 connected with calibrated equipment is arranged on a side panel 3 of the box body, a socket identification number is marked on the cross-linking interface 5, and the adapter jack 4 is connected with a corresponding contact pin inside the box body 1 through a wire. The transfer jack 4 comprises an excitation voltage jack and a synchronizer signal input/output jack. The cross-linking interface 5 is two aviation sockets with five holes and eleven holes.

As shown in fig. 2, when the attitude and heading device angle signal calibration adaptor box works, one end of the attitude and heading device angle signal calibration adaptor box is connected with a device to be calibrated, and the other end of the attitude and heading device angle signal calibration adaptor box is connected with a measurement standard instrument.

As shown in fig. 3, on the operation panel 2 of the attitude and heading equipment angle signal calibration adaptor box, a signal name and a signal direction are clearly marked, wherein:

excitation voltage-driving voltage signal of angle signal input/output.

And outputting the angle signal output by the metering standard instrument to a channel of the calibrated equipment from the outside through an output socket of the calibration adapter box.

Input-the angle signal of the calibrated equipment is input to the channel of the metering standard instrument through the calibration adapter box.

As shown in fig. 4-5, the cross-linking interface 5 of the calibration adaptor box side panel 3 is marked with socket identification numbers and pin serial numbers, wherein:

X1-Signal input port cross-linked to calibrated device. The calibrated angle signal enters the interior of the calibration adapter box through the X1 cross-linking port and is distributed to the heading, pitching and rolling signal seats of the input port of the adapter box through different pin pins in the cross-linking port.

X2-Signal Outlet crosslinked with the calibrated device. And standard signals of the metering standard instrument enter the calibrated equipment through an output port of a side panel of the calibration adapter box and a cross-linking port, so that external standard synchronous signals are provided for the calibrated equipment.

When the angle signal of the attitude and heading test device is calibrated, the matched test cable for the calibration adapter box is respectively connected with the X1 socket on the right side of the adapter box and the synchronous angle output of the rear panel of the attitude and heading test device

The outlet is connected with the socket. The calibration test wire is connected with holes S1, S2 and S3 of an output part of a heading synchronizer on the calibration transfer box, and is respectively connected with an excitation signal 26V/400Hz and an output signal S1, S2 and S3 corresponding to the angular position indicator. Clicking the calibration software of the screen, and entering a D/S module calibration program. Turn on the front panel "heading indicator" switch. And clicking the angle value to be tested to confirm, and gradually calibrating the angle value of the D/S module according to the test program. This test procedure is part of the derivation of the angle signal of the attitude and heading equipment to be calibrated with an external standard.

The calibration adapter box can also realize the function of reliably connecting the synchronous angle signal of the external standard to the tester to be calibrated. The X1 on the right side of the test box is connected with the X4 of the spare boat attitude rear panel by a special cable. Two 26V/400Hz excitation signal wires are removed from connection, and angle output holes S1, S2 and S3 on the calibration switching box are respectively connected with S1, S2 and S3 of a standard synchronous/resolver. The standard synchro/resolver is now set to 11.8VL-L, 400Hz, SYZ, INT functions for calibration. And opening a main power switch of the testing equipment, and switching on a 'heading indicator' switch of the front panel. And clicking calibration software to enter an S/D module calibration interface. And setting standard synchronizer/resolver output, wherein each 30-degree interval is a test point, transmitting the test point to an S/D module, and converting the test point into a value of a 'course angle' through the S/D module.

The introduction of the above two test methods is the most basic method for using the calibration adaptor box. In addition, the function of the calibration adapter box can be expanded by changing the definition of a cross-linking interface of a test connection cable of calibrated equipment, so that the calibration tasks of course angles, pitch angles and inclination angles of different types of attitude and heading equipment are realized, and the requirement of various types of attitude and heading testers on angle calibration of synchronizers can be met.
