多电表系统中的电量数据自动抄报方法 Meter Multi-system electric quantity data automatically send a copy of the method

技术领域 FIELD

[0001] 本发明涉及一种红外抄表方法,它能实现电表箱内多块电(能)表电量数据的自动上报。 [0001] The present invention relates to a method for infrared meter, it can achieve a plurality of electrical meter box (energy) quantity data table reported automatically.

背景技术 Background technique

[0002] 随着供电业的日益发展和科学技术的突飞猛进,抄表技术也在不断改进。 [0002] With the rapid development of the electricity supply industry and the growing science and technology, meter reading technology has been improved. 目前较为先进的抄表方法是利用红外抄表器抄报电表数据。 Currently more advanced method is to use an infrared meter reading meter reading copy to meter data. 采用这种抄表方法的前提是在线路中安装内置了以微处理器为核心器件并设置有红外通讯电路的电子计费电能表,抄表时首先向红外抄表器输入电能表的身份识别码,然后由红外抄表器向该电能表发出红外抄表信号,该电能表接收到此信号后将储存的电量数据以红外线形式传送给红外抄表器,红外抄表器将该表的电量数据存储在与该电能表的身份识别码相对应的存储单元内。 With this premise meter method is installed in the line of identity built microprocessor core and is provided with an infrared communication device of the electronic revenue meter circuit, first inputs to the meter when the meter is an infrared meter code and emitted by an infrared meter reading meter reading signal to an infrared meter, the power meter receives this signal after storing the data transmitted in the form of infrared rays to the infrared meter reading, the meter reader power infrared table the data stored in the storage unit and the identification code corresponding to the energy meter. 这种抄表方法速度快,数据便于存储,但现有的红外抄表方法每次操作只能抄收一块电能表的数据,适用于电表箱内只有一块电能表的情况,而且每次都需要人工输入电能表的身份识别码,限制了抄报效率。 This method of speed meter, to facilitate data storage, but the conventional method of infrared read only Collecting data for each operation of a meter, the meter box and only applies to the case of a power meter, and each time the need to manually meter input identification code, send a copy limit efficiency. 当表箱内存在6块,甚至更多块表时,则很难进行数据抄报,更不能实现对多块电表数据的同时抄报,这是因为红外抄表器向电能表发出红外抄表信号后,各表会同时向红外抄表器传送电量数据,这些数据之间会发生干扰,出现数据拥挤现象,使得各表的数据都不能成功上报。 When the presence of the meter box 6, even more block table, it is difficult to send a copy of the data, but can not achieve at the same time send a copy of the plurality of meter data, which is sent to the meter reader as an infrared meter infrared meter reading after the signal, each table will simultaneously transmit power to the infrared meter reading data, interference can occur between these data, the data congestion occurs, so that the data in the tables are not successfully reported.

[0006] 上述多电表系统中的电量数据自动抄报方法,为了防止多块电表上报数据时发生冲突并尽快上传数据,在电能表内设置一个150毫秒定时器,各电能表上传数据时应检测其它电能表是否正在发射红外信号,若没有发射红外信号则上传数据,否则停止上传数据并启动150毫秒定时器,此后每次检测到其它电能表发出的红外信号都重新启动150毫秒定时器,当定时到时后,若未检测到其它电能表所发出的红外信号,则上传数据,否则等待续抄信号。 [0006] The method of the electric quantity data automatically send a copy of said plurality of metering systems in order to prevent conflicts when a plurality of data reporting the meter data and upload quickly, a 150 millisecond timer is provided in the meter, each meter should upload the data detected if the other meter is transmitting an infrared signal, an infrared signal is not transmitted if the data is uploaded, the uploaded data and starts or stops the timer 150 milliseconds, after each detection of the infrared signal emitted from the other meter 150 millisecond timer restarting, when when the timer expires, the other is not detected infrared signal emitted by the meter, the upload data, or other signal copy continued.

[0007] 上述多电表系统中的电量数据自动抄报方法,为了提高抄表效率,首次抄表时,红外抄表器以闭环数据链条的形式将同一表箱内的多块电能表数据存储于抄表存储器中:第二只表的数据存储单元内同时记录第一只表在数据库中的位置,第三的数据存储单元内同时记录第二只表在数据库中的位置,依次类推,最后一只表的数据存储单元内同时记录倒数第二只表在数据库中的位置,第一只表的数据存储单元内同时记录最后一只表在数据库中的位置,下次抄表时,红外抄表器根据第一个上报电能表的数据存储单元中记录的另一只表在数据库中的位置读取该表信息并发出含有该表身份识别码的抄表命令,该表接收到含有自身身份识别码的抄表命令后上报电量数据,依次类推,红外抄表器沿闭环数据链条逐一读取本表箱内的所有电能表信息,直至所有电 [0007] The multi-meter system electric quantity data automatically send a copy of the method, in order to improve the efficiency of meter reading, meter reading for the first time, an infrared meter is in the form of a chain loop plurality of meter data same table data is stored in the tank Reading memory: first table position simultaneously recorded in the database, the third data storage unit while only the second recording position in the database tables, and so only the data storage unit of the second table, the last at the same time only the penultimate position of the record in the database table within the table data storage unit only, while recording the first data storage unit only one end of the table in the database table position, the next meter reading, meter reading IR table in the database is only position information is read in the table according to another data storage means a first reported by power meter and recorded in the table containing the commands issued meter identification code, the identification table containing the received identity itself after reporting the meter reading command code quantity data, and so on, one by an infrared meter reader to read all the information in this table meter box closed along the chain data until all of the electrical 能表的数据读取完毕。 Table data can be read is completed.

具体实施方式 detailed description

[0012] 首次抄表把所抄回来的同一表箱里的电能表数据在红外抄表器数据库中建立关联。 [0012] Reading the first copy of the same table box back to the meter in the infrared read data associated database. 以后可通过红外抄表器主动搜索表箱内的电能表,通过表号抄表。 After actively search meter in a meter box by infrared meter reading, meter reading by the table number.

[0013] 首次抄表[0014] 红外抄表器发送广播抄表命令(所谓广播抄表命令是指对表箱中所有电表发出的抄表命令,而不是针对某块电表发出的,即不含有单表身份识别码,所有接收到广播抄表命令的电表均需上传数据),命令中包含两个参数:表箱内电能表个数和延时因子(所谓延时因子是电表计算延时时间时使用的一个时长因子,延时时间是延时因子的整数倍,不同电表延时时间之差也是延时因子的整数倍,为避免不同电表上报数据时发生冲突,延时因子应大于单表上传数据所用时间)。 [0013] Reading the first [0014] IR meter reading device transmits a broadcast command meter (meter reading command is a command called a broadcast command table meter box meter all issued, instead of issuing the meter against a block, i.e., does not contain single table identification code, all the broadcast receiving meter data upload command required meter), the command comprising two parameters: the number of the meter box meter factor and delay (delay factor is called the delay time calculated meter when used for a long time factor, the delay time is an integer multiple of the delay factor, the delay time difference between different meter is an integer multiple of the delay factor, the meter to avoid conflicts when different data reporting delay factor should be greater than a single table Upload data elapsed time). 每块电能表用自身随机码生成器3产生的随机码除以两倍表箱内电能表个数,得到的余数乘以延时因子作为电能表的上报延时时间。 Each meter itself with a random code generator 3 generates a random code number divided by twice the meter the meter box, and the remainder is multiplied by a delay factor, as reported by the delay time meter. 每个电能表的延时时间到了,电能表就会自动通过红外通讯电路把数据上传给红外抄表器,红外抄表器会对收到的数据给一个确认,收到本表确认信息后的电能表在下一条抄表命令来之前不会再次自动上传数据给红外抄表器,其他没有收到本表确认信息的电能表可以通过红外抄表器返回给其他表的确认信息得到这次集抄还有多少个表没有被红外抄表器正确抄收,当第一轮延时都已结束,没有收到本表确认信息的电能表将根据未抄收成功电能表个数,延时因子和自身随机码重新计算延时时间,并在延时时间再次到达的时候自动上报电能表信息给红外抄表器,并主动结束本次红外抄表器对自身的集抄。 Each of the delay time to meter, the meter will automatically upload the data to an infrared meter via infrared communication circuit, data of the infrared meter reader will receive a confirmation to receive acknowledgment information after this table Reading a meter in the next command does not automatically upload the data to an infrared meter reading again come before the other did not confirm receipt of this form of energy meter information can return to the confirmation message to other tables via infrared meter reader to get the meter reading how many tables are not properly Collecting infrared meter, a delay when the first round have ended, this table does not receive acknowledgment information meter according to the number of not successful Collecting meter, and its own random delay factor then compute the delay time, the delay time and reaches again automatically when the meter reports the information to the infrared meter reading, and ends the active infrared read the meter reading device itself.

[0015] —般情况下,红外抄表器发送广播抄表命令,电能表两轮自动上报电能表信息就可以把所有电能表信息采集成功,如果在广播抄表命令失效后红外抄表器并没有接收到所有电能表的上报数据,红外抄表器就会通过广播续抄命令,继续等待电能表上报信息。 [0015] - Under normal circumstances, an infrared meter reading meter reading device transmits a broadcast command, the automatic reporting meter two meter information can collect all the meter information is successful, if the infrared read the meter reading command is broadcast after the failure and not received all the data reported by the meter, an infrared meter reader will continue through the broadcast copy command, continue to wait meter reporting information. 电能表在接收到续抄命令后,接收到红外抄表器确认信息的电能表不再进行延时上报操作,没有上报成功的电能表继续上报电表信息。 Upon receiving the meter continued copy command, an acknowledgment is received infrared read meter no longer delay information report operation, there is no report of success reported meter continues meter information.

[0016] 红外抄表器对接收的的每条有效的电能表上报信息,返回上报确认信息,并且利用计数器累计接收到的有效信息数,计数器的输出值为抄表器成功接收电表上报信息的个数,如果有效信息数达到表箱内电能表个数,那么红外抄表器会立即结束本次抄表。 [0016] reports an infrared meter for each valid meter received information, reports the returned acknowledgment information, and the number of effective use of the accumulated information received in the counter, the counter output is successfully received meter reading information reported by the meter number, if the number of valid information to reach the number of tables inside the meter, then the infrared meter reader will immediately end the current meter reading. 抄表结束后红外抄表器还可以根据系统时间和最后一条电能表信息中的电量参数计算出一个表箱号(用于下次集中抄表)和本次抄收的所有电能表信息储存到数据库中(每只电能表一条记录),并且根据每条记录在数据库中的记录序号,将这些记录建立一个闭环数据链条,闭环数据链条是由同一表箱中所有电表数据在抄表器存储器中的储存地址首尾相连形成的数据链条,这个数据链条形闭环成。 IR meter may also be calculated according to a power meter after the time parameters of the system and the last meter information in a meter box number (for next centralized meter reading), and all of this energy meter Collecting information stored in the database in (one record per meter), and each record in accordance with the record number in the database, the data chain will create a closed loop, the closed loop chain data by the same data table are all the meter box meter reading these records in memory data storage address chain formed end to end, this chain of data to form a closed loop.

[0017] 电能表随机延时和冲突的处理: [0017] Meter random delay and conflict processing:

[0018] 如果有电能表产生延时时间是一样的,它们发出去的数据可能就会被冲掉。 [0018] If there is a time lag meter time is the same, they are sent to the data it might be obliterated. 电能表会自动检测外部红外信号,如果检测到有一个电能表先发了,另外的电能表会停止发送信息,等红外信道上有150毫秒以上的空闲才会发(即使延时时间到了)。 Meter automatically detect the external infrared signal if the detected starting a power meter, the meter will stop the further transmission of information, and so there are more than 150 milliseconds infrared channel idle before issuing (even to the delay time).

[0019] 每个电能表有两轮自动上传的机会,对于在第一轮上传中没有成功的电能表,电能表在第二轮再上传数据,对于在两轮集抄中都抄不到的电能表,可以采用续抄的命令去抄表,红外抄表器的广播续抄命令下来,会告诉电能表总共有多少块电能表要续抄,对于已经抄到的电能表就不上传数据了,没有上传数据的电能表会自动延时上传。 [0019] There are two opportunities per meter automatically uploaded to upload in the first round was not successful power meter, the power meter upload data in the second round for the two sets of copy are not copied meter, continued copy command can be used to meter reading, meter reading infrared broadcast continued down the copy command, will tell the total number of blocks meter meter continued to copy, for copying the meter has not uploaded the data no upload data upload meter will automatically delay.

[0020] 非首次抄表 [0020] not the first time meter reading

[0021] 红外抄表器发送广播抄表命令,并且在接收到第一块电能表上报信息后,提取电能表身份识别码,在数据库中查找此身份识别码对应数据链和表箱号,当找到数据链后红外抄表器会依次提取同一表箱数据链中对应的身份识别码,通过身份识别码主动抄表,主动抄表时,每个抄表命令中含有一块电表的身份识别码,虽然表箱中所有电表都能接收到该命令,但只有接收到含有自身身份识别码的电表才上传数据,无需再被动等待。 [0021] IR meter reading meter reading device transmits a broadcast command and the reception of the first report information after a power meter, the power meter extracted identification code, looks for this identification code corresponds to the data link and the meter box number in the database, when infrared read sequentially after extraction will find the same data link identity code corresponding to the chain box data table by meter identification code active when active meter reading, meter reading commands contained in each of a meter identification code, Although the meter box meter can receive all the commands, but only received the meter itself contains identification code before uploading data, no longer passively wait. 其他操作和首次抄表相同。 Other operations and meter reading for the first time the same. 因为红外抄表器这时是主动去抄,占用了整个红外通讯的信道(没有150毫秒空闲信道),电表就算随机的延时到了,也是不能上传的。 Because this time is an active infrared meter reader to copy, occupies the entire infrared communication channel (150 ms no idle channel), even if the meter to a random delay, they can not upload.
