  • 准确

    准确,快速,方便地获得温度在现代企事业单位,厂房车间和家庭中有着越来越重要的意义。本文设计了一套基于MSC51单片机的温度采集系统。应用该系统可以即时、准确地获得两路温度参数(可扩展至256路),测温范围达0~125c,参数精确至0.25c,并可以现场控制欲采集的指定传感器的温度参数,通过数码管显示出来,通过RS232接口可连接至计算机,并通过监控软件观察实时数据和波形。该系统具有易扩展、精度高、成本低等特点,适宜现场监控,实验室,家庭等对温度有要求的场所。

  • 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. It is now a community project maintained at http://jsmpp.org Release procedure mvn deploy -DperformRelease=true -Durl=https://oss.sonatype.org/service/local/staging/deploy/maven2/ -DrepositoryId=sonatype-nexus-staging -Dgpg.passphrase=<yourpassphrase> log in here: https://oss.sonatype.org click the 'Staging Repositories' link select the repository and click close select the repository and click release License Copyright (C) 2007-2013, Nuruddin Ashr uudashr@gmail.com Copyright (C) 2012-2013, Denis Kostousov denis.kostousov@gmail.com Copyright (C) 2014, Daniel Pocock http://danielpocock.com Copyright (C) 2016, Pim Moerenhout pim.moerenhout@gmail.com This project is licensed under the Apache Software License 2.0.
