Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
FIG. 1 is a flow chart illustrating a method of data collection based on an electrical energy data sensor, according to an exemplary embodiment. The data acquisition method based on the electric energy data sensor is used for electronic equipment such as an intelligent metering control terminal, an intelligent metering control server and the like. As shown in fig. 1, the data acquisition method based on the electric energy data sensor may include the following steps.
And step S110, acquiring the electric energy data acquired by the electric energy data sensor.
Typically, the collection of power data is performed by a power data sensor.
The power data may include one or more of voltage, current, power, cumulative power usage, and the like.
The power data may be power data of a certain electric device or power data of a certain electric line.
Step S120, judging whether the change value of the electric energy data in unit time meets an electric energy data change threshold value of a preset association rule, if so, executing step S130; if not, no processing is carried out.
The electric energy data collected by the electric energy data sensor includes electric energy data collected at each time point.
It can be understood that the electric energy data sensor collects the electric energy data according to a certain collection frequency. When the acquisition frequency is large enough, the electric energy data of the electric equipment at any time point can be acquired.
The power data variation value is a variation value of the power data per unit time.
The unit time is a preset time interval length for calculating the change value of the electric energy data. For example, the unit time may be 1 second, 1 minute, or the like.
The electric energy data change value may be a change value of a certain kind of electric energy data, or may be a change value of a plurality of kinds of electric energy data.
The electric energy data change value can be a difference value of the electric energy data between two acquisition times, and can also be a ratio of the electric energy data between the two acquisition times; or the difference or ratio between the latest electric energy data and the average value of the electric energy data in unit time; or the maximum difference or ratio between the latest electric energy data and each electric energy data in unit time; the electric energy data change value can also be obtained by other forms of calculation, and the calculation forms of the electric energy data change value are not described one by one.
For example, if the acquisition time of the latest electric energy data D1 is 12:01:00 in beijing, the unit time is 1 minute, and the minimum or maximum electric energy data of the same type as the latest electric energy data D1 is D2 in 12:00:00-12:01:00 in beijing, the electric energy data change value C is D1/D2, or C is D1-D2.
The power data change threshold is a preset critical value of the power data change value.
It should be noted that the threshold for the change of the power data is adjustable. In the actual operation process, the electric energy data change threshold value can be adjusted according to the actual situation.
When the electric energy data change value reaches the electric energy data change threshold value, the change amplitude of the electric energy data in the corresponding period reaches the sending requirement, and at this time, the electric energy data is very likely to be abnormal. Therefore, when the electric energy data change value reaches the electric energy data change threshold value, the electric energy data are sent, and therefore the real-time monitoring of the power utilization state is achieved.
When the change value of the electric energy data does not reach the change threshold of the electric energy data, the change amplitude of the electric energy data in the corresponding period does not meet the sending requirement, the electric energy data is not abnormal, the electric energy data does not need to be sent, and the sending quantity of the electric energy data is reduced.
Step S130, the electric energy data collector actively sends the electric energy data collected last time in a unit time to the data receiving device.
When the electric energy data collector actively sends the electric energy data collected last time in the unit time to the data receiving equipment, a wireless communication mode or a wired communication mode can be adopted.
The electric energy data collected for the last time in the unit time is sent to the data receiving equipment in a wireless communication fee mode, and a radio frequency communication mode can be adopted. In an exemplary embodiment, the operating frequency of the radio frequency communication mode is between 425MHz and 438MHz, so that the transmission distance of the electric energy data is greatly increased.
Optionally, the radio frequency communication mode is a bidirectional work mode capable of receiving and transmitting. Therefore, the electric energy data acquisition unit can be used as data receiving equipment of other electric energy data acquisition units to receive the electric energy data sent by the other electric energy data acquisition units, so that linkage with the other electric energy data acquisition units is realized, and the relevance among different electric energy data acquisition units is greatly improved.
By using the method, after the electric energy data acquired by the electric energy data sensor is acquired, whether the change value of the electric energy data in unit time meets the trigger condition of the preset association rule is judged, and when the change value of the electric energy data in unit time meets the trigger condition of the preset association rule, the electric energy data acquisition unit actively transmits the electric energy data acquired last time in unit time to the data receiving equipment. Therefore, when the change value of the electric energy data is large, namely when the electric energy data changes suddenly, the electric energy data is sent, so that the real-time monitoring of the power utilization state is realized, the normal electric energy data does not need to be transmitted and sent, the transmission quantity of the electric energy data is greatly reduced, and the transmission efficiency of the electric energy data is effectively improved.
Fig. 2 is a description of details of step S130 shown according to the corresponding exemplary embodiment of fig. 1. As shown in fig. 2, the step S130 may include the following steps.
And S131, determining the electric energy data collected by the electric energy data sensor for the last time in the unit time.
As described above, the electric energy data sensor acquires electric energy data at a certain acquisition frequency. Therefore, the circuit data have a certain acquisition sequence.
Step S132, extracting an electric energy data value from the electric energy data collected last time, and sending the electric energy data value to the data receiving device of the electric energy data collector.
It should be noted that, under different time or different scenes, the power data values sent to the data receiving device may be different.
Therefore, when the change value of the electric energy data in unit time reaches the preset electric energy data change threshold value, the required electric energy data value extracted according to specific conditions is sent to the data receiving equipment of the electric energy data collector.
For example, when the electric energy data collected by the electric energy data sensor is obtained, the electric energy data collector performs the accumulated calculation of the electric quantity value in real time. Therefore, the accumulated electric quantity value calculated at the last collection in the unit time is the latest electric quantity value.
The required electric energy data value is sent to the data receiving equipment of the electric energy data acquisition unit, when the electric energy data is abnormal, the data receiving equipment receives the required electric energy data value while acquiring the latest electric energy data, the monitoring of the real-time power utilization state is effectively guaranteed, and the flexibility of power utilization monitoring is improved.
