  • JAVA SMPP 源码

    Introduction jSMPP is a java implementation (SMPP API) of the SMPP protocol (currently supports SMPP v3.4). It provides interfaces to communicate with a Message Center or an ESME (External Short Message Entity) and is able to handle traffic of 3000-5000 messages per second. jSMPP is not a high-level library. People looking for a quick way to get started with SMPP may be better of using an abstraction layer such as the Apache Camel SMPP component: http://camel.apache.org/smpp.html Travis-CI status: History The project started on Google Code: http://code.google.com/p/jsmpp/ It was maintained by uudashr on Github until 2013.

  • BTS50_datasheet

    The BTS5016SDA is a one channel high-side power switch in PG-TO252-5-11 package providing embedded protective functions. The power transistor is built by a N-channel vertical power MOSFET with charge pump. The design is based on Smart SIPMOS chip on chip technology. The BTS5016SDA has a current controlled input and offers a diagnostic feedback with load current sense and a defined fault signal in case of overload operation, overtemperature shutdown and/or short circuit shutdown.

  • AZ1117H

    The AZ1117 is a series of low dropout three-terminal regulators with a dropout of 1.15V at 1A output current. The AZ1117 series provides current limiting and thermal shutdown. Its circuit includes a trimmed bandgap reference to assure output voltage accuracy to be within 1% for 1.5V, 1.8V, 2.5V, 2.85V, 3.3V, 5.0V and adjustable versions or 2% for 1.2V version. Current limit is trimmed to ensure specified output current and controlled short-circuit current. On-chip thermal shutdown provides protection against any combination of overload and ambient temperature that would create excessive junction temperature.  The AZ1117 has an adjustable version, that can provide the output voltage from 1.25V to 12V with only 2 external resistors.

  • python爬虫获取大量免费有效代理ip--有效防止ip被封

    以后再也不用担心写爬虫ip被封,不用担心没钱买代理ip的烦恼了 在使用python写爬虫时候,你会遇到所要爬取的网站有反爬取技术比如用同一个IP反复爬取同一个网页,很可能会被封。如何有效的解决这个问题呢?我们可以使用代理ip,来设置代理ip池。 现在教大家一个可获取大量免费有效快速的代理ip方法,我们访问西刺免费代理ip网址 这里面提供了许多代理ip,但是我们尝试过后会发现并不是每一个都是有效的。所以我们现在所要做的就是从里面提供的筛选出有效快速稳定的ip。 以下介绍的免费获取代理ip池的方法: 优点:免费、数量多、有效、速度快 缺点:需要定期筛选 主要思路: 从网址上爬取ip地址并存储 验证ip是否能使用-(随机访问网址判断响应码) 格式化ip地址 代码如下: 1.导入包 import requests from lxml import etree import time 1 2 3 2.获取西刺免费代理ip网址上的代理ip def get_all_proxy():     url = 'http://www.xicidaili.com/nn/1'     headers = {         'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36',     }     response = requests.get(url, headers=headers)     html_ele = etree.HTML(response.text)     ip_eles = html_ele.xpath('//table[@id="ip_list"]/tr/td[2]/text()')     port_ele = html_ele.xpath('//table[@id="ip_list"]/tr/td[3]/text()')     proxy_list = []     for i in range(0,len(ip_eles)):         proxy_str = 'http://' + ip_eles[i] + ':' + port_ele[i]         proxy_list.append(proxy_str)     return proxy_list 1 2 3 4 5 6 7 8 9 10 11 12 13 14 3.验证获取的ip def check_all_proxy(proxy_list):     valid_proxy_list = []     for proxy in proxy_list:         url = 'http://www.baidu.com/'         proxy_dict = {             'http': proxy         }         try:             start_time = time.time()             response = requests.get(url, proxies=proxy_dict, timeout=5)             if response.status_code == 200:                 end_time = time.time()                 print('代理可用:' + proxy)                 print('耗时:' + str(end_time - start_time))                 valid_proxy_list.append(proxy)             else:                 print('代理超时')         except:             print('代理不可用--------------->'+proxy)     return valid_proxy_list 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 4.输出获取ip池 if __name__ == '__main__':     proxy_list = get_all_proxy()     valid_proxy_list = check_all_proxy(proxy_list)     print('--'*30)     print(valid_proxy_list) 1 2 3 4 5 技术能力有限欢迎提出意见,保证积极向上不断学习 ———————————————— 版权声明:本文为CSDN博主「彬小二」的原创文章,遵循 CC 4.0 BY-SA 版权协议,转载请附上原文出处链接及本声明。 原文链接:https://blog.csdn.net/qq_39884947/article/details/86609930

  • AD810

    PRODUCT DESCRIPTION The AD810 is a composite and HDTV compatible, current feedback, video operational amplifier, ideal for use in systems such as multimedia, digital tape recorders and video cameras. The 0.1 dB flatness specification at bandwidth of 30 MHz (G = +2) and the differential gain and phase of 0.02% and 0.04° (NTSC) make the AD810 ideal for any broadcast quality video system. All these specifications are under load conditions of 150 Ω (one 75 Ω back terminated cable). The AD810 is ideal for power sensitive applications such as video cameras, offering a low power supply current of 8.0 mA max. The disable feature reduces the power supply current to only 2.1 mA, while the amplifier is not in use, to conserve power. Furthermore the AD810 is specified over a power supply range of ±5 V to ±15 V.

  • AD8001AR

    transimpedance linearization circuitry. This allows it to drive video loads with excellent differential gain and phase perfor mance on only 50 mW of power. The AD8001 is a current feedback amplifier and features gain flatness of 0.1 dB to 100 MHz while offering differential gain and phase error of 0.01% and 0.025°. This makes the AD8001 ideal for professional video electronics such as cameras and video switchers. Additionally, the AD8001’s low distortion and fast settling make it ideal for buffer high-speed A-to-D converters. The AD8001 offers low power of 5.5 mA max (VS = ±5 V) and can run on a single +12 V power supply, while being capable of delivering over 70 mA of load current. These features make this amplifier ideal for portable and battery-powered applications where size and power are critical. The outstanding bandwidth of 800 MHz along with 1200 V/µs of slew rate make the AD8001 useful in many general purpose high-speed applications where dual power supplies of up to ±6 V and single supplies from 6 V to 12 V are needed. The AD8001 is available in the industrial temperature range of –40°C to +85°C.
