Drawings
Fig. 1 is a schematic structural diagram of a load identification data acquisition terminal according to an embodiment of the present invention.
Detailed Description
The present invention will be further illustrated with reference to the accompanying drawings and specific examples, which are carried out on the premise of the technical solution of the present invention, and it should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a load identification data acquisition terminal, including a current sampling unit 1, a voltage sampling unit 2, a metering module 3, a processing module 4, and a communication module 5.
The current sampling unit 1 includes a current transformer, a signal conversion circuit connected to the current transformer, and the like, and is used for collecting current data on the power line. Specifically, the current transformer generates an induced current according to the current on the power line, and the signal conversion circuit converts the induced current into a voltage signal for output.
The voltage sampling unit 2 is used for collecting voltage data on a power line, and comprises a voltage transformer, a transformation circuit and the like, wherein the voltage transformer is connected with the power line, outputs induced voltage according to the voltage of the power line, and is rectified and reduced by the transformation circuit and then converted into direct-current low-voltage output.
The metering module 3 is preferably of an ADE7763 model, and the metering module 3 is connected with the current sampling unit 1 and the voltage sampling unit 2 to receive current data and voltage data respectively collected by the current sampling unit 1 and the voltage sampling unit 2, and calculate the apparent power and the power factor of a load connected with the current power line according to the current data and the voltage data. It should be noted that calculating the apparent power and the power factor of the load connected to the current power line according to the current data and the voltage data is an existing function of the metering module 3, and detailed description of the specific principle is omitted.
The processing module 4 can adopt an STM32 single chip microcomputer, the processing module 4 is respectively connected with the metering module 3, the storage module 12 and the clock module 6, the processing module 4 firstly samples current data, voltage data, apparent power and power factor at a first sampling frequency with lower frequency, and controls the storage module 12 to store the received current data, voltage data, apparent power and power factor in real time, the clock module 6 is used for setting a time interval, and the processing module 4 controls to send data according to the set time interval. The processing module 4 calculates the active power and the reactive power according to the apparent power and the power factor respectively. Wherein the first sampling frequency is preferably 0.1 to 1 HZ. The processing module 4 monitors the rate of change of the current data, voltage data, active power and reactive power with the last sampled data. Generally, voltage data changes linearly according to power utilization time, and a large change rate is generally not caused by power utilization peak periods, but at the moment of starting a load with large power, a relatively obvious voltage change rate may exist, and when the load is put into operation or stops operating, current data, active power and reactive power are generally changed. When the change rate of the current data, the voltage data, the active power and the reactive power does not exceed the set threshold, for example, the change rate is lower than 1%, the working state of the load connected to the power line is considered to have no change, and when the change rate of any one of the current data, the voltage data, the active power and the reactive power exceeds the set threshold, the processing module 4 triggers to sample the current data, the voltage data, the apparent power and the power factor at a second sampling frequency with a higher frequency within a set time. The second sampling frequency is preferably 0.5 to 10 kHZ. The processing module 4 samples and monitors at a lower frequency during the period when the load is not changed, and sends data to the server in a packet mode at set time intervals, so that unnecessary calculation amount and data traffic can be saved. When the load changes, the processing module samples subsequent data at a second sampling frequency with higher frequency, and the server can extract data such as harmonic waves, electromagnetic interference and the like according to the data acquired at the second sampling frequency, so that the accuracy of identification is improved. It should be noted that the time for sampling at the second sampling frequency set by the processing module 4 may be 30 seconds to 2 minutes, and the time may be changed and set according to actual needs, the set time is counted from the time when the change rate of any one of the current data, the voltage data, the active power and the reactive power exceeds the set threshold, and if the change rate of any one of the current data, the voltage data, the active power and the reactive power exceeds the set threshold during the counting period, the counting is restarted, and the sampling time at the second sampling frequency is extended. The change rates of the current data, the voltage data, the active power and the reactive power can be set according to parameters of a load connected with the power line, and the change rates are smaller than the minimum change amount caused by the work change of the load connected with the power line, so that the accurate event detection, feature extraction and subsequent load identification are guaranteed.
The communication module 5 is connected with the processing module 4, and there are two mechanisms for the communication module 5 to send data, one is when the change rates of current data, voltage data, active power and reactive power do not exceed the set threshold, that is, the working state of the load connected with the power line does not change, the processing module 4 controls the communication module 5 to periodically send the current data, voltage data, apparent power and power factor collected at the first sampling frequency and the active power and reactive power calculated by the processing module to the server at the time interval set by the clock module 6, the other is when the change rate of any one of the current data, voltage data, active power and reactive power exceeds the set threshold, that is, one or some working states of the load connected with the power line change, at this time, the processing module 4 controls the communication module 5 to real-timely send the current data collected at the second sampling frequency, The voltage data, the apparent power and the power factor, and the active power and the reactive power calculated by the processing module 4 are sent to the server.
The power supply unit preferably comprises a switching power supply module 7 connected with the power line, a charging control circuit 8 and a change-over switch module 9 connected with the switching power supply module 7, the switching power supply module 7 can convert alternating current 220V voltage into direct current 12V voltage, the processing module 4 is respectively connected with the charging control circuit 8 and the change-over switch module 9, the charging control circuit 8 is connected with a storage battery 10, the processing module 4 is used for controlling the charging control circuit 8 to charge the storage battery 10, and a stabilized voltage power supply module 11 is connected between the change-over switch module 9 and the processing module 4. During normal use, the processing module 4 controls the change-over switch module 9 to connect the regulated power supply module 11 with the switching power supply module 7, and the regulated power supply module 11 converts the direct current 12V voltage output by the switching power supply module 7 into the direct current 5V voltage and supplies the direct current 5V voltage to the processing module 4, the metering module 3, the communication module 5 and the like for work. When the power line is out of voltage, power is supplied from the battery 10.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that other parts not specifically described are within the prior art or common general knowledge to those of ordinary skill in the art.
