以上是caportal.service在Ubuntu 14.04机器上运行的一个名为systemd服务的内容。我需要每 30 分钟重复一次该服务。我怎样才能做到这一点 ？

/home/pi/do.py

import requests,json
import netifaces as ni
import commands as cm


gateway=ni.gateways()['default'][ni.AF_INET][0]

IPaddr=ni.ifaddresses('wlan0')[ni.AF_INET][0]['addr']
mac=ni.ifaddresses('wlan0')[ni.AF_LINK][0]['addr'].upper().replace(':','-')
ssid=cm.getoutput('iwgetid -r')
Home="http://"+gateway+":8010/"

URL=Home+"login.html"
print URL
d={}
d['IdSession']=mac

d['AC']='1'
d['userlog']='vishnu'
d['userpass']='12345'
d['read']='checkbox'

try:
    if ssid=='machCochin':
        r=requests.post(URL,data=d)
        print r.status_code
        #raise ValueError("ERROR simulated")
    else:
        print "network is not machCochin"
except Exception as e:
    pass
