Flexible storage method of II-type concentrator

Abstract

The invention relates to a flexible storage method of a II-type concentrator, which dynamically calculates and allocates a new record length for each meter again when a meter file or an acquisition scheme in the II-type concentrator is changed. The method comprises two steps of record length calculation and data storage, wherein the record length calculation is used for calculating the maximum storage length of each data item configured by each acquisition scheme and meter archive information, and calculating the storage record length value of each meter, comparing the newly calculated storagerecord length value of each meter with the locally stored storage record length value of each meter, and rewriting the storage record length value of each meter into the internal data storage area; and the data storage being used for positioning a specific storage position where the time point is located according to the data information in the storage message and storing the data to the positioned storage position. According to the invention, under the condition of not consuming too much memory and FLASH space, the current service demand is realized, and the purpose of saving cost is furtherachieved.

Description

technical field [0001] The invention belongs to the technical field of electricity consumption information collection and measurement, and in particular relates to a flexible storage method of a Type II concentrator. Background technique [0002] At present, in the field of electricity consumption information collection, Type II concentrators begin to use object-oriented communication protocols for data communication. Since this protocol is very flexible in terms of scheme configuration and data retrieval methods, taking data collection as an example, different data items, For example, voltage, current, and power can be configured in different acquisition schemes, with different acquisition cycles and different storage timescales (voltage is stored with "task start time", current is stored with "data freeze timescale", power Stored in "relative to 0:00 of the current day") to collect separately, even if it is the same collection plan, the collected data content, the number o...

Problems solved by technology

Since the storage record length is allocated to each meter according to the maximum situation, a large amount of external data storage resources will be consumed, so a large-capacity external data storage is required for support, and many meters do not need to allocate so much storage at all during actual operation. space, resulting in a great waste of memory space, and once more business needs increase in the later period, it is possible that the current estimated storage space is not enough, and there is a risk of code upgrade in the later stage
