Problems solved by technology

[0004] Up to now, most of the compasses used in geological survey are mechanically designed, and a small part is electronic compass with single function. The above two kinds of compasses are used in geological survey, and there are the following shortcomings: (a) mechanical compass measurement error Compared with electronic compass, it has obvious disadvantages; (b) the existing electronic compass can only display and store data, and some with USB communication interface can only return to office The data is exported from the location, and the remote data transmission cannot be realized through the mobile terminal at the measurement site

Abstract

Provided are a three-dimensional electronic compass with Bluetooth communication and an operation method. A traditional compass is used for geological examination and has the disadvantages that a mechanical compass is large in measurement error and low in operation efficiency; an existing electronic compass can only display and store data. The three-dimensional electronic compass with Bluetooth communication comprises a shell and an internal circuit, the shell is a square shell and comprises a shell body (9) and an upper cover (12), and the internal circuit (1) is arranged in the shell body and comprises an ARM processor (5), a nine-axis posture circuit (7), a data storage circuit (4), a protocol conversion circuit (3), a Bluetooth sending and receiving circuit (2) and a power source management circuit (6). A keyboard and a display circuit (8) are further arranged on the shell, the shell body and the upper cover are connected through a pin shaft (11), and a display screen is embedded into the upper surface of the shell body.

Description

[0001] Technical field: [0002] The invention relates to the field of surveying, in particular to a three-dimensional electronic compass with bluetooth communication and an operation method.
