[0038] C、用对标回路实现快速底度走齐试验 [0038] C, together with the test go to the bottom of the standard loop fast

[0039] 本发明实施例能对每个待测电能表的电压回路采用继电器单独控制,可以使处在同一电压电流回路中的各待测电能表所走电量均不相同,从而实现了待测电能表底度走齐的要求。 [0039] Example embodiments of the present invention can be employed individually controlled relay circuit voltage measured for each meter, the test meter can each at the same voltage and current in the loop are not the same power down, thereby achieving the test table at the end of the power requirements go together. 具体实现方法是让每个表位的误差板依次收到N1,N2,….个脉冲后,自动断开本表位电压继电器,实现对标功能;同时,本发明实施例有独立的对标电流回路,对标电流采用单相线输出小电流的形式,具有电流断开迅速的特点,从而使各表位的止度更加接近。 The specific method is to have each epitope plate sequentially received error N1, N2, ... after the pulse, automatically disconnect the epitope voltage relays, to achieve the scaling function;. Meanwhile, embodiments of the present invention is independent of standard current loop, the current in the form of the standard single-phase small current is output, having a rapid current interruption characteristics, so that the stop of each epitope closer. 具体实现算法如下: Specific algorithm is as follows:

[0040] Sl :对所有待测电能表的起码进行降序排序,假设排序序后的序列为〈sl,s2,…, Sn〉, sl > s2 > s3,…; [0040] Sl: all tested at least energy meter descending order, the sort order is assumed that the sequence is <sl, s2, ..., Sn>, sl> s2> s3, ...;

[0041] S2 :求出电能表码差的最大值AEmax,根据待测电能表电压、电流、接线方式等参数,计算底度走齐所需的最短时间Tmin,用户可以动态删除表码相差太大的电能表,以使Tmin最小,节省走字时间; [0041] S2: finding the maximum difference meter code AEmax, test meter according to the parameters voltage, current, wiring, etc., the bottom of the calculated minimum time required to flush away of Tmin, the user can delete tables dynamic code difference is too large energy meter, so that the minimum Tmin, saving time take the word;

[0042] S3 :设置所有表位底度走齐后的终止示数为S(S > Sl),计算每个待测电能表所走的电量AE1,AE2, •••, AEn(AEi = S-Si),显然序列(AE1, AE2, •••, AEi)也呈降序排列; [0042] S3: Set all the epitopes of the bottom down the number shown after the termination of Qi S (S> Sl), calculated for each test are taking electricity meter AE1, AE2, •••, AEn (AEi = S -Si), apparently sequence (AE1, AE2, •••, AEi) also showed a descending order;

[0043] S4:先使表底度最大的表位走到止度S,所需的电能为AE。 [0043] S4: to make the maximum of the table at the end of the epitope of the stopper come S, electric power required is AE. 为了使电表的止码最大限度接近止度S而且尽可能地縮小走字时间,把AE分成用普通电流回路输出的电能和用对标电流回路输出的电能,分别记作AE—a禾P AE—b,其中AE_a= AE*95%, AE_b = AE*5% ;[0044] S5 :走字时,先用Imax或者Ib输出,按照定电量的方法走字快速走字,走字电量为AE—a;然后用对标电流输出,采用定脉冲数走字,走字电量为AE—b,根据电表常数换算成脉冲数P,则表位电压控制继电器会在收到P个脉冲后自动切断该表位的电压输出,该表位的走字试验结束; In order to maximize the proximity meter stopper of the stop S and reduced down time as much as possible words, with the AE into a normal current loop output power and the power of the output current loop with the standard, are designated as AE-a Wo P AE -b, wherein AE_a = AE * 95%, AE_b = AE * 5%; [0044] S5: when word go, with the first output Imax or Ib, according to the method given amount of fast walking away word characters, words take charge of AE -a; then the output of the target current, using the number of pulses given word go, power take the word of AE-b, according to the terms of the meter constant pulse number P, the voltage control relay epitope will automatically cut off after receiving the pulses P the epitope voltage output, the end of the epitope walking test word;

[0045] S6 :对于剩下的Nl块表,重复S2-S5的步骤,均可快速实现电表底度走齐。 [0045] S6: Nl block table for the rest, repeat the step S2-S5, the bottom of the meter can be achieved quickly go together. [0046] 本发明实施例的电表底度走齐方法具有走字时间短的特点,因为采用对标回路输出电流,脉冲数控制法切断表位电压,又能使待测电能表的底度更加接近。 [0046] substrate of the present invention, an embodiment of the meter to go down a short flush method having the characteristics of word time, because the use of the bottom of the cutting loop labeled epitope voltage output current, pulse number control method, but also make the test more energy meter close. 该发明方法支持同种类型(相同电压、电流、接线方式),不同等级不同常数表的底度走齐。 The method of the invention supports the same type (same voltage, current, wiring), the bottom of the different levels of different constant table walk together. [0047] D、支持多功能协议配置管理。 [0047] D, support for multi-function protocol configuration management.
