Abstract

The utility model discloses an adaptation test device for an inertial element. The top end of the test device is provided with jacks corresponding to a concave-convex adapting plate on the inertial element; one corresponding serial number is arranged below each pin and each pin hole on the jacks; according to the needs of various test-maintenance items, the pins and the pin holes which correspond to each other are prolonged and solidified onto an electronic circuit board and one single-link interlocking switch is used for controlling on-off between every two parts; and the switch is connected with a universal meter terminal. In test, the concave-convex adapting plate of the inertial element is inserted into a corresponding jack on the test device; the number identification on the jack can definitely indicates the number of the corresponding pin; a universal meter probe is inserted into a meter probe jack; a switch corresponding to an item to be tested is selected; and the numerical value on the universal meter can be read. The adaptation test device is convenient and simple to use and avoids test result error resulting from false touching which is caused by the over-small volumes and the close arrangement of the pins and the pin holes.

Description

A kind of inertance element switching test device

Technical field

The utility model relates to a kind of inertance element switching test device, belongs to the proving installation field.

Background technology

Inertial navigation system is the equipment of navigation datas such as a kind of position that is used for measuring carrier, attitude; Inertance element then is the core devices of inertial navigation system; Its precise structure is complicated, and price is very expensive, and its output accuracy will directly determine the output accuracy of inertial navigation system.

Inertance element commonly used at present has floating integrating gyroscope of single-degree-of-freedom liquid and the floating pendulum-type integrating accelerometer of single-degree-of-freedom liquid; They are that floating packaging body is disposable combines by the liquid of a sealing; Output quantity (the motion angular velocity of gyroscope sensitive carrier that their inside is responsive separately; The acceleration of accelerometer sensitive carrier) heart yearn through element internal exports two concavo-convex card extenders to, and the system that is transferred to uses through concavo-convex card extender.Because inertance element is a disposable packaging body, therefore all can only carry out through concavo-convex card extender to each item test of inertance element.

Concavo-convex card extender is the output interface of inertance element internal signal; Its volume is very little, and the length and width height only has 0.4 * 3.8 * 1.0cm respectively, and total in the above 24 stitch or the pin hole of reaching; Arrange very closely; And do not have stitch number or pin hole number to be used for indication, and the test maintaining of inertance element need use multimeter to contact the stitch or the pin hole of concavo-convex card extender in twos, operation easier is very big like this; Usually the stitch or the pin hole on next door are run in the clerical mistake of brightness generation multimeter in practical operation, will cause test result inaccurate.Therefore need a kind of device and can accurately test inertance element, avoid because the error that operation is caused, and then have influence on whole inertial navigation system.

The utility model content

The utility model relates to a kind of inertance element test switching device; In order to avoid since on the buckplate stitch with pin hole is too tiny and arrange the test closely cause and slip up; The test error that is caused makes test convenient, safeguards the performance of inertial navigation system.

The method that the utility model adopted is: a kind of inertance element switching test device; The device top be with inertance element on the corresponding interface of concavo-convex card extender; There is corresponding numbering each stitch on the interface and pin hole below, according to the needs of each item test maintaining project, with corresponding stitch and pin hole prolongation and be cured to electronic circuit board; And between in twos, control break-make with the simply connected interlock switch, switch and multimeter binding post always join.

This device is simple and easy to use, avoided since on the concavo-convex card extender stitch and pin hole too tiny, arrange closely, mistake is touched when causing test, causes the test result mistake.

Description of drawings

The utility model will explain through example and with reference to the mode of accompanying drawing, wherein:

Fig. 1 is the utility model structural drawing;

Fig. 2 is the utility model circuit diagram.

Embodiment

Disclosed all characteristics in this instructions, or the step in disclosed all methods or the process except mutually exclusive characteristic and/or the step, all can make up by any way.

Disclosed arbitrary characteristic in this instructions (comprising any accessory claim, summary and accompanying drawing) is only if special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, only if special narration, each characteristic is an example in a series of equivalences or the similar characteristics.

Like Fig. 1, shown in Figure 2; A kind of inertance element switching test device, the device top be with inertance element on the corresponding interface of concavo-convex card extender, each stitch 1 on the interface has corresponding numbering 3 with pin hole 2 belows; Needs according to each item test maintaining project; Corresponding stitch 1 and pin hole 2 are prolonged and be cured to electronic circuit board, and between in twos, control break-make with simply connected interlock switch 5, switch and multimeter binding post 4 always join.

When detecting; At first the concavo-convex card extender with inertance element inserts interface corresponding on the test switching device; Digital ID on the interface can clearly be indicated corresponding stitch number; The multimeter test pencil is inserted the test pencil jack, select the test event corresponding switch of wanting, the numerical value on the multimeter of staying alone gets final product.This device is simple and easy to use, avoided since on the concavo-convex card extender stitch and pin hole too tiny, arrange closely, mistake is touched when causing test, causes the test result mistake

The utility model is not limited to aforesaid embodiment.The utility model expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.

Claims

1. inertance element switching test device; It is characterized in that, the device top be with inertance element on the corresponding interface of concavo-convex card extender, corresponding numbering (3) is arranged below each stitch (1) on the interface and the pin hole (2); Needs according to each item test maintaining project; Corresponding stitch (1) and pin hole (2) are prolonged and be cured to electronic circuit board, and between in twos, control break-make with simply connected interlock switch (5), switch and multimeter binding post (4) are total to be joined.
