问题描述

目前我正在做一个基于 Django 和 GREENTEL 的 GPS 跟踪项目它使用这个协议http://www.m2msolution.eu/doc/Fejlesztoi_dokumentaciok/GT03/GPRS%20Communication%20Protocol_GT03.pdf

Currently I am doing a GPS Tracking project based on Django and GREENTEL It uses this protocol http://www.m2msolution.eu/doc/Fejlesztoi_dokumentaciok/GT03/GPRS%20Communication%20Protocol_GT03.pdf

它说如何将纬度/经度转换为十六进制.. 但我想将纬度十六进制数据转换为正常形式

It says how to convert Latitude/ Longitude to Hex.. but I want to convert latitude hex data to the normal form

转换方法:A 将纬度(度、分)数据从GPS模块变成了一种新的形式,仅以分钟为单位表示值;B 将转换后的值乘以 30000,然后转换结果为十六进制数.例如22°32.7658′,(22*60+32.7658)*30000 =40582974,然后将其转换为十六进制数0x026B3F3E

Conversion method: A Convert the latitude (degrees, minutes) data from GPS module into a new form which represents the value only in minutes; B Multiply the converted value by 30000, and then transform the result to hexadecimal number. For example 22°32.7658′,(22*60+32.7658)*30000 = 40582974,then convert it to hexadecimal number 0x026B3F3E

如何反转十六进制到纬度的转换?

how to reverse the hex to latitude conversion?

推荐答案

首先你得到十六进制,将它转换回以 10 为底,然后除以 30000.

First you get the hex, convert it back to base 10 and divide it by 30000.

得到结果并除以60,整数部分为度数,其余为分钟数.

Get the result and divide it by 60, the integer part will be the degrees, the rest will be the minutes.

在python中:

a = 0x026B3F3E
b = a/30000.0
degrees = b//60
minutes = b%60

print degrees, ' degrees and ', minutes, 'minutes'
>>> 22.0  degrees and  32.7658 minutes
