Question

我想使用Python套接字将GPS数据(longitude, latitude)发送给另一个。每次运行它都会出错，我的代码是否正确？谢谢。我想将GPS数据发送到另一台服务器，因为数据将被处理为距离。

import serial
import math
import socket
gps = serial.Serial("/dev/ttyUSB0", baudrate=4800)
HOST = '192.168.10.1'
PORT = 4444
BUFFER_SIZE=1024


def longlat():
    global lon
    global lat
    while True:
        line = gps.readline()
        data = line.split(",")
        if data[0] == "$GPRMC":
            if data[2]== 'A':
                latgps = float(data[3])
                if data[4]=='S':
                    latgps = -latgps

                latdeg = int(latgps/100)
                latmin = latgps - latdeg*100
                lat = latdeg+(latmin/60)

                longps = float(data[5])
                if data[6]=='W':
                    longps = -longps

                londeg = int(longps/100)
                lonmin = longps - londeg*100
                lon = londeg+(lonmin/60)


longlat()
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((HOST,PORT))
s.send(lon,lat)
data = s.recv(BUFFER_SIZE)

我使用此代码更改我的代码

import time
from socket import *

import serial

host = '192.168.11.11'
gps = serial.Serial("/dev/ttyUSB0",baudrate=4800)
port = 4444
bufsize = 1024
addr = (host, port)
client = socket(AF_INET, SOCK_STREAM)
client.connect(addr)
while True:
    global lon
    global lat
    line = gps.readline()
    data = line.split(",")
    if data[0] == "$GPRMC":
        if data[2] == 'A':
            latgps = float(data[3])
            if data[4] == 'S':
                latgps = -latgps

            latdeg = int(latgps / 100)
            latmin = latgps - latdeg * 100
            lat = latdeg + (latmin / 60)

            longps = float(data[5])
            if data[6] == 'W':
                longps = -longps

            londeg = int(longps / 100)
            lonmin = longps - londeg * 100
            lon = londeg + (lonmin / 60)
    # for i in range(1, 5):
    data = ""
    for j in range(1, 20000):
        rlt = lon
        data = rlt
    client.sendall(data[:-1])
    print ("client send data to server")
    time.sleep(5)
    # break
client.close()

我收到错误NameError: global name 'lon' is not defined 也许你有解决方案？
