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

The method of ammeter address under a kind of automatic search collector
Technical field
The present invention relates to method, especially search for the method for ammeter address under the collector, to obtain the address of ammeter the ammeter address searching.
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 ammeter address under a kind of automatic search collector, this 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, the method for ammeter address comprises the steps: under a kind of automatic search collector
(1) sending the asterisk wildcard address by concentrator to collector excites collector to gather the data of all ammeters;
(2) collector will be given concentrator in the data back that 1~3S collects, and by concentrator the data of gathering be analyzed; The process of analyzing is:
1) free of data input judges that then no ammeter inserts;
2) have and receive complete data, and the back is with any other data, then judging has single ammeter to insert, thereby obtains the address of single ammeter;
3) search element to data be that mess code, error message or correct message back also have other data, then judging has the polylith ammeter to insert;
(3) when search inserts for multilist, replace the asterisk wildcard address and repeat above-mentioned steps (1), (2) till the address that searches the 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 search out the ammeter address automatically, like this, not only reduce a large amount of manual workings, reduced maintenance cost, and, improved efficient greatly.
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 the RS485 bus collision process, analyze the method that obtains all ammeter addresses under the collector, the efficient height of exchanges data, accurate.
As improvement, be judged to be no ammeter when inserting, 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 when inserting, obtain the ammeter address after, 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.

Fig. 2 is search ammeter integral module block diagram;
Fig. 3 is search ammeter flow chart;
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 the RS485 bus collision process, analyze the method that obtains all ammeter addresses under the collector.The method of ammeter address under the 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 will be given concentrator 1 in the data back that 1~3S collects, and be analyzed by the data of 1 pair of collection of concentrator; Select 2S in the present embodiment; The process of analyzing is:
1) free of data input judges that then no ammeter inserts; 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 with any other data, then judging has single ammeter to insert, thereby obtains 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, then judging has the polylith ammeter to insert;
(3) when search inserts for multilist, replace the asterisk wildcard address and repeat above-mentioned steps (1), (2) till the address that searches the 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 showing, replace rank-1; Multilist is replaced rank+1; Do not have table, replace to 00H;
99H: during single showing, replace rank-1; Multilist is replaced rank+1; Do not have 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 the 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 search out the ammeter address automatically, like this, not only reduce a large amount of manual workings, reduced maintenance cost, and, improved efficient greatly.
