Abstract
The invention discloses a method for automatically searching an electric meter address below a collector, comprising the following steps: 1, a concentrator sends a wildcard address to the collector and excites the collector to collect the data of all electric meters; 2, the collector sends the data collected in 1-3S back to the concentrator, and the concentrator analyzes the collected data, wherein the analysis process is that: (1) if no data is input, no electric meter is accessed; (2) if a complete data is received and no other data is followed, a single electric meter is accessed; (3) if the searched data is messy codes, error messages or correct message and other data is followed, a plurality of electric meters are accessed; 3, and when search shows that a plurality of electric meters are accessed, the wildcard address is replaced to repeat the step 1 and the step 2 till the address of the single electric meter is searched. The method can reduce maintenance work of an electric power information collecting system, reduces maintenance cost, and increases running effect of the collecting system.
Description
Technical field
The present invention relates to the method to method, the especially searching electric meter address below collector of electric meter address search, to obtain the address of ammeter.
Background technology
In the process of building intelligent grid, in order to promote electrical network and user's two-way interaction ability and electricity consumption value-added service level, the scale of power information acquisition system is increasing, and the system maintenance work amount is increasing, and maintenance cost is also increasing.Maintenance issues has more and more restricted the operational effect of whole power information collector.
Original maintenance mode is to connect 50 collectors under concentrator, connects 32 tables under each collector, and the parameter of these tables can only be by artificial preparation, and not only workload is made mistakes greatly but also very easily.
Summary of the invention
The object of the present invention is to provide the method for electric meter address under a kind of automatic search collector, the method can reduce the maintenance work in the power information acquisition system, reduces maintenance cost, improves the operational effect of acquisition system.
For achieving the above object, under a kind of automatic search collector, the method for electric meter address, comprise the steps:
(1) sending the asterisk wildcard address by concentrator to collector excites collector to gather the data of all ammeters;
(2) the collector data back that will collect at 1～3S is to concentrator, by the data analysis of concentrator to gathering; The process of analyzing is:
1) countless according to input, judge without ammeter and access;
2) have and receive complete data, and the back is determined with single ammeter access not with any other data, thereby obtain the address of single ammeter;
3) search element to data be that mess code, error message or correct message back also have other data, be determined with the access of polylith ammeter;
(3) when search accesses for multilist, replace asterisk wildcard address repetition above-mentioned steps (1), (2) until search the address of monolithic ammeter.
Method provided by the invention has improved the maintenance efficiency of power information acquisition system, and with respect to prior art, method of the present invention can go out electric meter address by automatic search, like this, not only reduce a large amount of manual workings, reduced maintenance cost, and, improved greatly efficient.
As improvement, collector carries out exchanges data by RS485 bus and ammeter.Utilize to produce mess code or misdata and conflict free normal data in RS485 bus collision process, analyze the method that obtains all electric meter address under collector, the efficient of exchanges data is high, accurate.
As improvement, be judged to be without ammeter fashionablely, change traffic rate and asterisk wildcard address, system is searched for again.Can improve search efficiency like this.
As improvement, be judged to be the monolithic ammeter fashionable, after obtaining electric meter address, change traffic rate and asterisk wildcard address, system is searched for again.Can improve search efficiency like this.
Specialize as of the present invention, the method for replacing the asterisk wildcard address is: be divided into 6 grades by the position of intending replacing: begin to replace from lowest byte.To improve the accuracy of search.
As improvement, after the replacement rank surpasses 6 grades, change baud rate and communications protocol repeating step (1), (2) and (3) ammeter is carried out address searching.Like this, can guarantee to search all ammeters.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.
Method of the present invention is the order that a kind of asterisk wildcard that utilizes ammeter agreement DLT645-1997/2007 is read electric weight, utilize to produce mess code or misdata and conflict free normal data in RS485 bus collision process, analyze the method that obtains all electric meter address under collector.The method of electric meter address under automatic search collector as shown in Figure 1 to Figure 3, step is:
(1) sending the asterisk wildcard address by concentrator 1 to collector 2 excites collector to gather the data of all ammeters 3; In the present embodiment, asterisk wildcard is AAAAAAAAAAAA first.
(2) collector 2 data back that will collect at 1～3S is to concentrator 1, by the data analysis of 1 pair of collection of concentrator; Select in the present embodiment 2S; The process of analyzing is:
1) countless according to input, judge without ammeter and access; At this moment, change traffic rate and asterisk wildcard address, system is searched for again, improve the efficient of search;
2) have and receive complete data, and the back is determined with single ammeter access not with any other data, thereby obtain the address of single ammeter; And change traffic rate and asterisk wildcard address, and system is searched for again, improve the efficient of search;
3) search element to data be that mess code, error message or correct message back also have other data, be determined with the access of polylith ammeter;
(3) when search accesses for multilist, replace asterisk wildcard address repetition above-mentioned steps (1), (2) until search the address of monolithic ammeter.
In the present embodiment, the method for replacement asterisk wildcard address is: be divided into 6 grades by the position of intending replacing: begin to replace from lowest byte.For example the 0th grade the time, prepare to replace the byte of lowest order; Prepare the byte of replacement:
AAH: during single table, replace rank-1; Multilist is replaced rank+1; Without table, replace to 00H;
99H: during single table, replace rank-1; Multilist is replaced rank+1; Without table, replace rank-1;
Less than 99H: multilist is replaced rank+1; Single table, nothing table, table number adds one;
Greater than 99H: this EO;
After the super scope of rank after replacement, this EO.
After the replacement rank surpasses 6 grades, change baud rate and communications protocol repeating step (1), (2) and (3) ammeter is carried out address searching.
Method provided by the invention has improved the maintenance efficiency of power information acquisition system, and with respect to prior art, method of the present invention can go out electric meter address by automatic search, like this, not only reduce a large amount of manual workings, reduced maintenance cost, and, improved greatly efficient.
