Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
With the development of an electric power system, a plurality of data information of a plurality of electric energy meters need to be collected simultaneously, if one collection terminal corresponds to N electric energy meters, and each electric energy meter has M data to be collected, then N × M data need to be collected finally, the traditional single-shot data, that is, one data information which can only be transmitted to one electric energy meter is transmitted once, and a large amount of time needs to be consumed to collect all the data, so that the electric energy meter information cannot be transmitted in real time.
In order to improve the information acquisition and transmission efficiency, concurrent data acquisition is proposed to be used in the electric power energy acquisition equipment, that is, for N electric energy meters, each electric energy meter needs to acquire M data, and multiple data can be simultaneously acquired in one power line, so that the information acquisition time is shortened, and the real-time performance of the data is improved.
However, since the technology is still immature at present, it is not clear how to actually perform data transmission, and more importantly, the currently proposed concurrent acquisition method cannot implement adaptive adjustment, and one kind of communication can only be applied to a specific acquisition terminal, and once the communication method is applied to other types of acquisition terminals, transmission cannot be implemented due to mismatch of data capacity and the like.
Therefore, the invention researches and improves the concurrent acquisition applied to the electric power energy acquisition equipment, and discloses the adaptability of the acquisition method. In an implementation method of the present invention as shown in fig. 1, an automatic control concurrent data collection method for an electric energy collection device is provided, where the electric power system has N electric energy meters, each electric energy meter needs M data to be collected, the M data may be attribute parameters of voltage, current, electric power, etc. of the electric energy meter, and in order to distinguish each attribute parameter, a data code, i.e. ID, may be designed for each parameter, where ID ═ 1 may be commanded to represent the voltage of the electric energy meter, ID ═ 2 represents the current of the electric energy meter, ID ═ 3 represents the electric power of the electric energy meter, etc., and a specific ID may be determined according to actual situations.
After acquiring data transmitted from the outside, the acquisition device packages the data and converts the data into data to be transmitted, and at this time, a transmitting end of the acquisition device is in a transmitting state, namely, corresponding to a "transmitting state" of the leftmost end in fig. 1, and then performs the following operations:
s1: detecting whether the acquired data meet the sending condition, if so, executing S2, and otherwise, executing S3;
s2: sending the data, operating the data according to the corresponding transmission protocol, acquiring a next data object, and executing S1 again to realize concurrent acquisition of the data;
s3: and receiving and processing the data to obtain an error code of the data, correcting the error code, and feeding back the corrected information to a sending end of the acquisition equipment to realize self-adaptive adjustment.
In S2, after the next data object is obtained, the process of sending and receiving the previous data is repeated from the leftmost end of the flowchart, so that data acquisition, data sending, and data receiving are performed continuously through a loop operation, thereby implementing a concurrent acquisition function.
In S3, the receiving end receives the data and processes the data, i.e., analyzes why the data does not satisfy the transmission condition, to find the cause, i.e., the error code. In the present invention, specifically, the error code includes,
a1: the quantity of concurrent table records exceeds the limit;
a2: the amount of concurrent data is overrun.
After the error code is derived, the error code is corrected by the adaptive adjustment function to obtain parameters suitable for the properties of the current acquisition device, i.e. correcting the error code in S3 includes,
b1: adjusting and recording the quantity according to the characteristics of the acquisition equipment and the data received by the receiving end;
b2: and adjusting the quantity of the concurrent data according to the characteristics of the acquisition equipment and the data received by the receiving end.
If the data to be sent meets the sending condition, sending and transmitting are performed, and the specific relevant conditions of transmission are judged in the transmission process, so as to determine whether the data can be sent continuously and uninterruptedly, specifically, the operation of the data according to the corresponding transmission protocol in S2 includes,
and C1, in the process of transmitting the data, detecting and judging whether the concurrent record number exceeds the limit, if so, executing S3. That is, if the number of the electric energy meters acquired at this time has reached the upper limit of the capacity of the acquisition device, new data acquisition cannot be performed, the state needs to be changed to a receiving state, and after the data is received, redundant channel positions are vacated, and the next data can be transmitted. D1: if the quantity of the concurrent records is not over-limit, continuously detecting whether the sending buffer area is full, if so, executing D2;
d2: setting a sending mark, and executing D3; that is, the capacity of the sending buffer area reaches the maximum at the moment, and in order to enable the data transmitted subsequently to have a position to be stored, the data flag is set as the sending flag, and the data is sent out so as to vacate the corresponding position.
D3: and increasing the current concurrency number of times, judging whether the next-record data acquisition is successfully carried out at present, if so, increasing the record once, executing the step S2 of acquiring the next data object, and executing the step S1 again to realize the concurrent acquisition of the data.
E1: if the sending buffer is not full, continuing to detect whether the receiving buffer is full, if so, sequentially executing D2 and D3.
F1: if the receiving buffer is not full, analyzing and processing the current data, judging whether the current recording address needs to be changed, if so, sequentially executing D2 and D3. For operation F1, a specific operation principle is that, assuming that data in the current channel is data of the nth (N < N) th electric energy meter, once the data is sent out, data acquisition of the nth electric energy meter is completed, data acquisition of the (N +1) th electric energy meter is to be immediately acquired next time, and in order to ensure integrity of the data acquired by each electric energy meter, even if the capacity of the receiving buffer at this time does not reach the upper limit, and the length and the number of the current data concurrent messages do not reach the upper limit, D2 and D3 are still skipped to be executed, that is, the current data is sent first, and then data acquisition of the (N +1) th electric energy meter is performed.
Further, the operation of the data according to the corresponding transmission protocol in S2 further includes,
g1: if the current address does not change, continuously detecting whether the quantity of the concurrent messages exceeds the limit, if so, sequentially executing D2 and D3. Namely, if the quantity of the current data concurrent messages reaches the upper limit of the capacity, immediately sending the data to vacate redundant positions to facilitate the transmission of subsequent data.
H1: and if the quantity of the concurrent messages is not over-limit, replacing the data numbers, executing the step S2 to obtain the next data object, and executing the step S1 again to realize the concurrent acquisition of the data. If the length or the number of the current messages does not reach the upper limit, the next data can be collected and transmitted, the data collected by one electric energy meter is multiple, different attribute parameters have different ID numbers, the next data is collected through the change of the ID values, namely the next data object is obtained, and then the processes of sending, transmitting and detecting the previous data are sequentially repeated until all the data are collected.
According to the method, data which do not meet sending conditions are analyzed, the condition that the data cannot be sent, namely the capacity of the communication mode is possibly not matched with the capacity of the current acquisition equipment, the communication capacity of the current communication mode is changed through self-adaptive adjustment, and the communication capacity is fed back to the acquisition end of the acquisition equipment, so that self-updating adjustment is carried out according to different acquisition equipment, data matching is achieved, and the usability of the concurrent acquisition method is enlarged; meanwhile, the acquisition method carries out address allocation on each table mark by encoding each attribute parameter to be acquired, detects and judges a plurality of capacity areas in the transmission process, sets a sending mark when the capacity of the capacity areas reaches an upper limit, sends data and vacates redundant capacity, thereby ensuring reliable and effective transmission of the data and improving the efficiency of concurrent acquisition and the real-time property of the data.
In addition to the above-mentioned modifications, other similar modifications are also included in the scope of the modifications of the present invention, and are not described herein in detail.
While embodiments of the invention have been shown and described, it will be understood by those skilled in the art that: many changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
