Brief description of the drawings
Accompanying drawing is to be used to provide a further understanding of the present invention, and forms a part for description, withDetailed description of the invention one is below used from explanation the present invention, but is not construed as limiting the invention. ?In accompanying drawing:
Fig. 1 is the flow chart that explanation a kind of electronic compass of the present invention refers to northern precision correcting method.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated. Should be understood that,Detailed description of the invention described herein only, for description and interpretation the present invention, is not limited to thisBright.
The invention provides a kind of electronic compass and refer to northern precision correcting method, this electronic compass refers to northern precision correctionMethod comprises:
Step 1, is fixed on electronic compass in the normal workspace of place system electrical equipment, by electronic compassConnect electricity normally to work with described system electrical equipment;
Step 2, carries out and refers to northern precision correction electronic compass.
Under system electrical equipment environment when electronic compass is fixed on its normal work by the present invention, electronic compass withThe Serial Port Line that between PC, verification needs completes communication through reserved Serial Port Line hole in its system architecture, at thisIn the situation of kind, complete checking procedure (different electronic compass, checking procedure and the interface that electronic compass carriesAll different), verification under the system electrical equipment environment in the time that electronic compass is normally worked.
By above-mentioned embodiment, the present invention can be good at solving the accessory of electronic compass as systemWhen use, refer to that northern performance is subject to the impact of system electrical equipment environment and the problem that declines improves electronics sieve greatlyThe progress of dish, the electromagnetic interference of avoiding system electrical equipment to produce in the process using, improves electronic compass and existsMeasurement precision in electrical equipment. Simple to operate, cost is low, and verification the verifying results is good.
Below in conjunction with accompanying drawing 1, the present invention is further detailed, in the present invention, in order to improve thisThe scope of application of invention, realizes by following detailed description of the invention especially.
In a kind of detailed description of the invention of the present invention, the method can comprise: in step 2, measureThe error in the finger north on electronic compass working face, then revises electronic compass and issues the data of display screenBag, to finely tune the finger north effect on display screen. By above-mentioned mode, can be to the finger north of electronic compassEffect is carried out test and debugging, and amendment shows.
In this kind of embodiment, the error approach of measuring the finger north on electronic compass working face comprises:Multiple electronic compass interval the first preset angles are rotated, and corresponding multiple default accurate one by onePut, successively the physical location of electronic compass is adjusted to accurate location sample and preserve obtain first numberAccording to. By above-mentioned mode, electronic compass can be rotated with the first preset angles, thereby to oftenIndividual position is adjusted.
In this kind of embodiment, the quantity of described the first preset angles is 18, and is distributed in wholeOn rotational plane. The adjustment that 18 preset angles complete whole plane upper angle is set.
In this kind of embodiment, the first preset angles is 20 degree, the equally spaced angle to electronic compassDegree is adjusted. By the way, can realize planar alignment the Sampling hold of 360 degree.
