Embodiment 1

[0062] An intelligent power monitoring method, such as Figure 4 As shown, it includes a server 100 and several collection units, the collection unit is connected to the server 100, and a communication connection is established between several collection units, and the collection unit includes a concentrator 200 and several data collectors 300, such as figure 1 shown, including the following steps:

[0063] S1. The data collector 300 by cycle T 1 Collect A, B, and C three-phase voltage data; the concentrator 200 periodically sends voltage test instructions and receives data according to the device number of the data collector 300 from small to large, and the cycle is T 2 ;

[0064] S2. The concentrator 200 judges whether the phase voltage is greater than 198V and less than 236V. If it matches, it jumps to S3. If it does not meet, it makes a fault judgment. The fault judgment is that if the concentrator 200 fails to receive data, the phase voltage is 0V and the phase voltage ...

Embodiment 2

[0103] An intelligent electric power monitoring system, this embodiment is further improved on the basis of Embodiment 1, such as Figure 5 , Image 6 As shown, the concentrator 200 in this embodiment also includes a charging module 1200, a lithium battery 1300 and a temperature and humidity sensor 1400, the power supply module 400 and the lithium battery 1300 are connected to the charging module 1200, and the MCU 500 and the temperature and humidity sensor 1400 are connected to the lithium battery 1300 The data collector 300 also includes a temperature and humidity sensor 1400, which is connected to the MCU500. The power supply module 400 charges the lithium battery 1300 through the charging module 1200. After the external power supply is interrupted, the lithium battery 1300 can guarantee power supply for more than 24 hours. The reported ambient temperature data error should be within ±40%, and the ambient humidity data error should be within ±30%. %, the temperature and hu...

Embodiment 3

[0105] An intelligent power monitoring method. This embodiment is further improved on the basis of Embodiment 1. The 1# concentrator 200 is used as the first transmission concentrator 200, and the 2# concentrator 200 is used as the backup transmission concentrator 200. Only 1. The 2# concentrator 200 is connected to the server 100, and the 2# concentrator 200 sends a fault query call test command to the 1# concentrator 200 at a period t. If the 1# concentrator 200 has no fault, the 2# concentrator 200 and other The concentrators 200 all transmit the data packets to the 1# concentrator 200 and upload them to the server 100; if the 1# concentrator 200 fails, the 1# concentrator 200 becomes invalid, and the other concentrators 200 transmit the data packets to the 2# concentrator 200 Then upload server 100. All the other methods are the same as in Example 1.

[0106] The beneficial effects of the present invention are as follows: through the concentrator 200, the data packets are...

Abstract

The invention discloses an intelligent power monitoring method comprising a server and a plurality of acquisition units, the acquisition units are connected with the server, communication connection is established among the plurality of acquisition units, each acquisition unit comprises a concentrator and a plurality of data acquisition units, and the method comprises the following steps: the dataacquisition units acquire voltage data; the concentrator sends a voltage interrogation instruction to the data collector; the concentrator judges the phase voltage; the concentrator counts the numberof the data collectors with successful data collection; the concentrator directionally sends a data packet interrogation instruction to the data collector; the integrity of the interrogation data isjudged; the data packet is encrypted and the encrypted data packet is uploaded to a server; and voltage and current thresholds are judged, and data is checked and updated in the threshold table. The method and the system have the beneficial effects that the concentrator periodically calls the data packets, judge and process the data packets and checks and update the threshold table data, so that the effect of automatically updating the threshold is achieved; and data packet encryption is also provided, so that the security of data packet transmission is improved.

Description

technical field [0001] The invention relates to the field of monitoring equipment for power network inspection, in particular to an intelligent power monitoring system and method. Background technique [0002] Using the installation of intelligent monitoring devices to make the power grid more intelligent is an important means for the construction of smart grids in power supply enterprises. When these intelligent monitoring devices perform data analysis, they usually use the preset threshold of the device to compare with the real-time collected data. Set the threshold condition to get the result of whether it needs to be processed, the design is simple and highly sensitive to data fluctuations. However, the current threshold preset methods are as follows: one is to preset during the installation and commissioning of the first installation site; the other is to set the default value by the manufacturer; the third is to correct it on site according to the default value of the ...
