Before the technical solution of the embodiment of the present invention is introduced, an application scenario is exemplarily described. The technical scheme of the embodiment of the invention can be applied to the condition that the on-line monitoring device needs to be checked so as to ensure the normal operation of the on-line monitoring device. It can be understood that sulfur hexafluoride gas is used as an insulating medium in the commonly used closed combined electricity in the power grid, and partial discharge of the sulfur hexafluoride gas can be monitored by adopting a partial discharge online monitoring device, so that the normal operation of the closed combined electricity is ensured.

As shown in fig. 1, the method includes:
s110, when first data collected when the analog partial discharge signal is emitted at the first partial discharge sensor based on the analog signal generator is received, a first partial discharge map is obtained.
The analog signal generator may be a generator for generating an analog partial discharge signal, the analog partial discharge signal may be a partial discharge signal that is simulated by the analog signal generator, the partial discharge signal may generally be a pulse signal, the first partial discharge sensor refers to a sensor for collecting the analog partial discharge signal, and the first data may be signal data obtained by collecting and converting the analog partial discharge signal by the first partial discharge sensor. The first partial discharge spectrum may be understood as a spectrum for characterizing a partial discharge.
Specifically, the analog signal generator can transmit an analog partial discharge signal at the position of the first partial discharge sensor, the first partial discharge sensor can acquire the analog partial discharge signal, filter and amplify the analog partial discharge signal to obtain first data corresponding to the analog partial discharge signal, and send the first data to the background system, so that the background system can analyze and calculate the data, and then generate a first partial discharge map.
On the basis of the above technical solution, obtaining the first partial discharge map when receiving the first data acquired when the analog signal generator transmits the analog partial discharge signal at the first partial discharge sensor includes: sending a control signal to an analog signal controller to cause the analog signal controller to control the analog signal generator to emit an analog partial discharge signal at the first partial discharge sensor based on the control signal.
The control signal may be a signal sent by a background system, and the analog signal controller may receive the signal, so that the background system may remotely control the analog signal controller. The analog signal controller may be configured to trigger the analog signal generator to emit an analog partial discharge signal.
Specifically, for convenience of checking the online monitoring device, communication between the background system and the analog signal controller may be established in advance, for example, the communication mode may be 5G communication or micropower wireless communication, so that the background system may remotely control the analog signal controller. Specifically, the background system may send a control signal to the analog signal controller, and the analog signal controller may trigger the analog signal generator based on the received control signal, so that the analog signal generator may transmit the analog partial discharge signal at the first partial discharge sensor. The online monitoring device has the advantages that the analog signal generator can be remotely controlled through the background system, so that the online monitoring device can be checked, and the analog signal generator does not need to be manually triggered.
S120, when the analog signal generator emits the analog partial discharge signal, the analog partial discharge signal is collected based on the second partial discharge sensor, and when second data corresponding to the analog partial discharge signal is received, a second partial discharge map is determined.
The second partial discharge sensor may be understood as a sensor for collecting an analog partial discharge signal, the second data may be signal data obtained by collecting and converting the analog partial discharge signal at the first partial discharge sensor by the second partial discharge sensor, the second partial discharge sensor and the first partial discharge sensor are arranged at different positions, and the second partial discharge map may be understood as a map for representing partial discharge.
Specifically, when the first partial discharge sensor emits the analog partial discharge signal, the analog partial discharge signal may be acquired by the second partial discharge sensor, and after the analog partial discharge signal is acquired, the analog partial discharge signal is processed, for example, filtered and amplified, to obtain second data corresponding to the analog partial discharge signal, and the second data is sent to the background system, so that the background system may analyze and calculate the data, and further generate a second partial discharge map.
On the basis of the technical scheme, the analog signal generator is arranged at a position adjacent to the first partial discharge sensor and far away from the second partial discharge sensor.
In particular, the analog signal generator may be arranged at a close distance from the first partial sensor, for example, around the first partial sensor. And the position of the analog signal generator is far away from the second partial discharge sensor, so that the channel validity check can be carried out on the first partial discharge sensor, and the coverage range check can be carried out on the second partial discharge sensor.
In practical application, an analog signal generating device, namely a plurality of analog signal generating devices, can be arranged around each partial discharge sensor or on the corresponding insulating basin in the sulfur hexafluoride closed type combined electrical appliance in advance, so that when an analog partial discharge signal needs to be transmitted at a certain partial discharge sensor, the analog signal generating device around the partial discharge sensor or on the corresponding insulating basin can be controlled to transmit the partial discharge signal. The advantage of such setting lies in, set up corresponding analog signal generating device in each partial discharge sensor department in advance, can direct remote control corresponding analog signal generating device, can launch partial discharge signal.
S130, determining a target verification report based on the first partial discharge map and the second partial discharge map.
The target verification report may be understood as a verification report of the online monitoring device, and the target verification report may be a document file, and the target verification report includes verification specific information of the online monitoring device.
Specifically, a first partial discharge map and a second partial discharge map can be displayed on a display interface of the background system, and the first partial discharge map and the second partial discharge map are subjected to screenshot, so that a target verification report is generated.
On the basis of the technical scheme, the first partial discharge map and the second partial discharge map comprise amplitude information and phase information of the analog partial discharge signal. The partial discharge map contains the amplitude and the phase of a partial discharge pulse signal, and whether the partial discharge condition of the current closed combined electrical is serious or not is judged usually based on the amplitude, the phase and the like, and the closed combined electrical is enough to be maintained, so that accidents caused by equipment failure are avoided.
On the basis of the above technical solution, the determining a target verification report based on the first partial discharge map and the second partial discharge map includes: deriving the first partial discharge map and the second partial discharge map to generate the target verification report.
Specifically, the first partial discharge map and the second partial discharge map may be exported to a standardized file by an export method, or whether the first partial discharge map and the second partial discharge map are qualified or not may be judged according to a judgment standard of the partial discharge maps, so as to generate a verification report.
According to the technical scheme, when first data acquired when an analog partial discharge signal is transmitted at a first partial discharge sensor based on an analog signal generator is received, a first partial discharge map is obtained; when the analog signal generator emits an analog partial discharge signal, acquiring the analog partial discharge signal based on a second partial discharge sensor, and determining a second partial discharge map when second data corresponding to the analog partial discharge signal is received; and determining a target verification report based on the first partial discharge map and the second partial discharge map.

Example two
Fig. 2 is a flowchart of a verification method applied to an online monitoring device according to a second embodiment of the present invention, in which a detailed description is provided for channel validity verification of a first partial discharge sensor and coverage verification of a second partial discharge sensor in this embodiment, and a specific implementation manner of the verification method may refer to a technical solution in this embodiment. The technical terms that are the same as or corresponding to the above embodiments are not repeated herein.
As shown in fig. 2, the method includes:
s210, when first data collected when the analog partial discharge signal is emitted at the first partial discharge sensor based on the analog signal generator is received, a first partial discharge map is obtained.
S220, when the analog signal generator emits the analog partial discharge signal, the analog partial discharge signal is collected based on the second partial discharge sensor, and when second data corresponding to the analog partial discharge signal is received, a second partial discharge map is determined.
And S230, determining a channel validity check result of the first local sensor based on the first local map.
The channel validity check can be understood as checking the acquisition of the first partial discharge sensor and the transmission channel, determining whether the first partial discharge sensor can acquire the analog partial discharge signal, and sending the analog partial discharge signal to the background system after processing.
On the basis of the above technical solution, the determining a result of checking validity of a channel of the first localized sensor based on the first localized map includes: detecting the analog partial discharge signal based on the first partial discharge sensor, and if first data corresponding to the analog partial discharge signal is received and a first partial discharge map is generated based on the first data, determining that validity check of a first partial discharge sensor channel is successful.
Specifically, if the first partial discharge sensor can normally detect an analog partial discharge signal, and process and convert the analog partial discharge signal into a first data transmission background system, and the background system can normally receive the signal, generate a first partial discharge map based on the signal, which indicates that the channel verification of the first partial discharge sensor is successful. It can be understood that, if the first local discharge sensor can normally detect the analog local discharge signal, the corresponding background system may also receive and process the signal sent by the first local discharge sensor, which indicates that a detection channel of the first local discharge sensor to the analog local discharge signal is normal, that is, the first local discharge sensor in the online monitoring device may have a capability of detecting the local discharge. The method has the advantages that the validity of the channel is checked for the first partial sensor, so that the first partial sensor can normally detect, and the situation that the detection is wrong or cannot be detected is avoided.
S240, determining a coverage verification result of the second partial discharge sensor based on the second partial discharge map.
It should be noted that a plurality of partial discharge sensors are arranged in the closed combined electrical system, and the closed combined electrical system includes a plurality of electrical devices, and the partial discharge sensor at the current position can detect the electrical device at the current position generally, but after the sensor at the current position goes wrong, the partial discharge phenomenon occurs in the electrical device at the current position, and the partial discharge phenomenon cannot be detected, which may cause device damage and damage to the power grid, resulting in power failure. Therefore, the partial discharge sensor at the current position is required to normally detect the analog partial discharge signals at other positions, that is, when the partial discharge sensor at other positions is damaged, the analog partial discharge signals at other positions can still be detected by the partial discharge sensor at the current position.
The coverage verification may be understood as verifying a coverage of the partial discharge sensor, that is, whether the partial discharge sensor at the current position can detect analog partial discharge signals at other positions.
On the basis of the above technical solution, the determining a coverage verification result of the second partial discharge sensor based on the second partial discharge map includes: and detecting the analog partial discharge signal based on the second partial discharge sensor, and if second data corresponding to the analog partial discharge signal is received and a second partial discharge map is generated based on the second data, determining that the coverage verification of the second partial discharge sensor is successful.
Specifically, the analog partial discharge signal at the first partial discharge sensor can be detected by the second partial discharge sensor, and if the analog partial discharge signal can be detected, the second data is obtained by processing the analog partial discharge signal, and the second data is sent to the background system, so that the background system can generate a second partial discharge map based on the second data, which indicates that the coverage verification of the second partial discharge sensor is successful, that is, the second partial discharge sensor can normally detect the analog partial discharge signal at the first partial discharge sensor.
And S250, determining a target verification report based on the channel validity verification result and the coverage verification result.
Specifically, after determining that the channel validity check of the first partial discharge sensor is successful and the coverage verification of the second partial discharge sensor is successful, the corresponding first partial discharge map, the second partial discharge map, the channel validity check result, and the range check result may be stored in a document, and the document may be used as a target check report.
In this embodiment, after checking the channel validity of the first partial discharge sensor and checking the coverage of the second partial discharge sensor, the analog partial discharge signal may be transmitted at the position of the second partial discharge sensor, and the analog partial discharge signal is not transmitted at the position of the first partial discharge sensor.
In practical application, the technical scheme can not only carry out coverage verification between two partial discharge sensors, but also carry out coverage verification between three or more partial discharge sensors. It is understood that, the partial discharge sensors included in the enclosed combined electrical interior are usually multiple, and the method described above can be adopted for checking the channel validity of each partial discharge sensor. For the coverage verification of the partial discharge sensor, because the analog partial discharge signal is attenuated along with the distance, when the coverage verification is performed on the current partial discharge sensor, analog partial discharge signals can be transmitted at other partial discharge sensors within a certain range from the current partial discharge sensor, and if the current partial discharge sensor can detect the analog partial discharge signal, the coverage verification of the current partial discharge sensor can be considered to be successful.
For example, the distance range may be set to be 5m or 8m, the current partial discharge sensor is an a partial discharge sensor, in the closed combined circuit, the other partial discharge sensors at a position less than 5m or 8m from the a partial discharge sensor are a B partial discharge sensor, a C partial discharge sensor, and a D partial discharge sensor, at this time, analog partial discharge signals may be transmitted at positions of the B partial discharge sensor, the C partial discharge sensor, and the D partial discharge sensor, and if the a partial discharge sensor can detect the analog partial discharge signals at three positions, it may be considered that the coverage verification of the a partial discharge sensor is successful. According to the technical scheme of the embodiment of the invention, when first data acquired when an analog partial discharge signal is emitted at a first partial discharge sensor based on an analog signal generator is received, a first partial discharge map is obtained; when the analog signal generator emits an analog partial discharge signal, acquiring the analog partial discharge signal based on a second partial discharge sensor, and determining a second partial discharge map when second data corresponding to the analog partial discharge signal is received; and determining a target verification report based on the first partial discharge map and the second partial discharge map.
According to the technical scheme, the first partial discharge sensor emits the simulation partial discharge signal, the first partial discharge map and the second partial discharge map are respectively obtained based on the simulation partial discharge signal detected by the first partial discharge sensor and the second partial discharge sensor, and the verification report is determined, so that the problem that the online monitoring device is low in verification efficiency manually in the prior art is solved, the online monitoring device is automatically verified, and the verification efficiency of the online monitoring device is improved.
