电能表485通讯地址(安科瑞电能表485通讯地址表)

很难通过485总线获得某一声电能表的表地址，但是你可以看电表铭牌，输入电表表号后面的几位数字就可以抄到全表号（目前很多电表都直持缩位抄表）。如果发送万能表号，所有表计都反应，抄不到东西，如果表号错误，所有表计都不响应。

deep sky, light rain Lin Zhao. Cold, a person. Particularly the past two days the wind, showered and then confused depressed, really depressed. Tired today, filling the legs like lead, sink to death, little effort has not. And half a day in bed. Thought of him, feeling very afraid, really do not want to think anymore. In fact, sometimes, the feeling is very wonderful thing. I was too headstrong, and live too tired. blame should not say those words, Gan Mafei say it? Even really know, I would rather guess guess go, once the pierce the layers of paper, once the words out of the mouth, everything changed, like ... ...sad hearts that faint and can not heal wound, this time do not even know that their heart will never heal my wounds, maybe his injury is too deep, dark night outside the window, no stars, nor the moon, the air inside the trace of a spring cold, not the least bit warm, and only around the vent noise is enough to cover my heart loneliness and helplessness, and the mood is too complicated.I'm not happy, it is difficult to make others happy, making it difficult for people really like me, get close to me. This is what I have been afraid of being understood, fear of being close to the root cause of it. I fear that others in my cynical, carefree facade found a weak, poor, lonely soul, then, and then leave me.very tempting, I have been in his shadow. Advantages and Disadvantages may be too, what this episode is not in my heart always emerge. Understand just know want to see him, he is not always laugh, but I still think he looks like. Now many things are forgotten, but many forget some things but to remember more clearly, and read more to understand, seems to be the case.like to look back, and was only a go forward, there is no plan, no summary. Now some consciousness, or pick up emotions and continue to go forward. Again my heart is full of melancholy, know all the irreversible end to end and we have to know that life is not all romantic, and understand before the end of the former, and understand the end of the end is the end ... ... if sincerely deceived by hypocrisy, love changes become a source of pain.have a very good feeling. Each morning, especially in the sunny morning, stuck his head out from under the covers, see the bright light almost equal over, and my heart twitch for a while. I asked myself: What living? Every day I tell myself to happiness, why should I be strong can it? I am not happy, but also nothing worth happy.listening to sad songs, or see the scene scene, a scene, the heart often look to be sharp to tingling, pain,ladies long jackets, wanted to call time, do not want to talk,ladies plus size clothes, it's not no one to talk, it is This melancholy gratuitous. I do not know why, even though I know the feeling may be due from his sad, lost the focus of life, loss of reason to busy, very sad. This is hurt badly the point, it seems fine, but I put great passion all gone, this time with memory and tears into the soul collection.all this is why it? Seems not the case, because I doubt if I would give up hope. Think too much, and too concerned with feeling, it do not even know his own. I always think is not really such thing as fate, is not a lot of things in life are destined to a good strategy?thought, there are always people willing to listen to me tell, that is no longer in this world I'm the second person said. I thought, as I am a fool in this world ... ... one far horizon near, to be a long road to Solo travelers it. Cold, a person.distress, and asked bleak courtyard, repeated spring evening?silence in the passage of time, space operation. Can be thought or occupy my brain, emotions occupy my mind. In this silence, thinking of the emergence of heart fibrillation. In this quiet rain in a row without a break. The original time can become ugly and beautiful, the tender into the rough. Maintain a familiar, a distant and vague acquaintance, and in this world of right and wrong, is not to be more real, more beautiful and some of it? When spring came, I bless you in the distance. Again later this spring, this spring I do not know to go through several times. But, this time, I was cold, a person ... ...

在智能电表中，集中器到智能电表端使用RS485总线作为通讯，主要传输每一户的用电量信息，用电量信息通过集中器传输到电力公司，集中器传输到电力公司有两种做法，一种是使用交流载波技术，也叫电力线载波，顾名思义就是在电力线上叠加高频的通讯信号，在接 受端再解调出来。这是用于人比较多的区域如小区等场所，还有一种做法是使用无线技术如GPRS，一般这种做法用于比较偏远的地区如山区/变电站等。在智能电表的应用中，RS485总线的使用是有局限的，因为本身在楼宇里面使用，设备又有强电系统接入，RS485的抗干扰能力较薄弱，其主机带负载能力较弱，一般在32个节点以内比较稳定。且从机需要加隔离，成本较高。每一个RS485的智能电表需要集中器输出4根线与之通讯供电，施工也很复杂且不稳定。近几年有出现使用POWERBUS总线技术代替RS485总线接口做的智能电表，其主要特点是集中器到电表只需要两根线，完成通讯兼供电的功能，而且带负载能力极强，主机能支持512个节点且从机无极性，已有芯片方案。
按照《DL/T 645-2007多功能电能表通信协议》，通过RS485通信线可以读出电能表的各种数据，如各种电量，电表的各种参数，并且可以配置电表参数，如修改密码，设置费率等。可以用串口调试助手进行测试。
RS485通讯口 是 串行通信接口之一 线路简单、传输距离远还可以 组成 网络推荐看看百度百科请看 武汉鸿伟光电 有 485 连接示意图
RS485接口是一种数据通讯接口，是RS232通讯接口的“升级版”，比RS232的电器性能提高很多。具体见 http://baike.baidu.com/view/196467.htm。 “电能表”，是不是指的是“电度表”？现代的电度表多是采用数字式计量并显示，电度表使用RS232通讯口与电网管理部门连接，随时掌握用户的用电情况。

默认的通常是0000或0001，当然是可以改的了。
设备出厂的默认ID一般都是1，当然可以更改。在同一条485总线挂接多个设备时，每个设备的ID，不能有重复，否则无法正确访问。

1.电脑要有485转232的转换器 2.你要看懂DLT_645—1997规约的通讯协议,现在大多电能表厂都会遵行这个通讯协议,DLT_645—1997规约不是最新的通讯协议.就看电表的使用什么通讯协议.3.要知道电能能的通讯地址,不知道也没关系,可以单表通讯,用12个9当地址.就可以读出来.4.用mscomm32.ocx控件访问串口； 你用要一点编程基础； 总之,按协议编程很重要,我有过成功经历.也没有那么难呀.
1.你要有485转232的转换器；花钱买的，台湾moxa； 2.你要知道电能表的串行对话协议；一般不会让你知道的，除非你跟电表厂家联系；3.你用mscomm32.ocx控件访问串口； 你用要一点编程基础； 这三点一般人我是不告诉的
