一开始是用的这种方法，发现不行，不知道什么原因，我测试的时候要么运行一次，要么运行两次，反正后面程序就是不跑了。。。

import os
import sched
import time

from scrapy.commands import ScrapyCommand
from scrapy.utils.project import get_project_settings
schedule = sched.scheduler(time.time, time.sleep)


# 被周期性调度触发的函数
def func():
    os.system("scrapy crawl bai")
    os.system("scrapy crawl sync_handel")
    # os.system("scrapy crawl ***")

def perform1(inc=60*10):
    schedule.enter(inc, 0, perform1, (inc,))
    func()

def mymain():
    schedule.enter(0, 0, perform1, (600,))

if __name__ == "__main__":
    mymain()
    schedule.run()

一顿艰辛的搜索尝试，最后用的这种方法可以了

def _crawl(result, spider):
    deferred = process.crawl(spider)
    deferred.addCallback(lambda results: print('waiting 100 seconds before restart...'))
    deferred.addCallback(sleep, seconds=100)
    deferred.addCallback(_crawl, spider)
    return deferred


_crawl(None, 'bai') # 第二个参数是爬虫名
_crawl(None, 'sync_handel')
process.start()
