[0055] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with Figures 1-5.

[0056] An embodiment of the present application provides an online monitoring method for plum blossom moving contacts based on multi-parameter fusion information feedback. The method can be applied to an online monitoring device for plum blossom moving contacts based on multi-parameter fusion information feedback. The executor of the method can be an online monitoring terminal in the online monitoring device for plum blossom moving contacts based on multi-parameter fusion information feedback.

[0057] The following will be combined with specific implementation methods. Figure 1 The processing flow shown is described in detail, and the content can be as follows:

[0058] S101, receiving status monitoring data fed back by a multi-parameter fusion sensor in real time, the status monitoring data including a temperature value of the plum blossom moving contact, a clamping force value of the plum blossom moving contact on the static contact, and an insertion depth value of the plum blossom moving contact inserted into the static contact.

[0059] In implementation, the multi-parameter fusion sensor includes a pressure detection sensor, a laser matrix sensor, and a temperature sensor.

[0060] Among them, the pressure detection sensor can contact the outer side of the spring contact finger on the plum blossom moving contact. When the stationary contact is inserted into the plum blossom moving contact, the spring contact finger is deformed, so that the pressure detection sensor can detect the clamping force value of the plum blossom moving contact on the stationary contact. The laser array sensor emits a laser. After the stationary contact is inserted into the plum blossom moving contact, the laser array sensor detects the insertion depth value of the stationary contact by detecting multiple beams of laser reflected from the stationary contact. The temperature sensor is used to detect the temperature value of the plum blossom moving contact.

[0061] The online monitoring terminal receives status monitoring data fed back by multiple parameter fusion sensors in real time. The status monitoring data includes the temperature value of the plum blossom moving contact, the clamping force value of the plum blossom moving contact on the static contact, and the insertion depth value of the plum blossom moving contact into the static contact.

[0062] S102, generating status alarm information or status warning information according to preset status threshold data and status monitoring data.

[0063] In implementation, the online monitoring terminal compares the currently received state monitoring data with the state threshold data, wherein the state threshold data includes a depth threshold, a clamping force threshold, and a temperature threshold. Specifically, the online monitoring terminal compares the current temperature value with the temperature threshold, proportions the current clamping force value with the clamping force threshold, and compares the insertion depth value with the insertion depth threshold, so as to analyze the current state alarm information or state warning information.

[0064] S103: If status warning information is generated at the current time, an estimated maintenance time is generated based on the status warning information.

[0065] In implementation, after the online monitoring terminal generates the status warning information at the current moment, it generates an estimated maintenance time based on the current status warning information, so as to generate an estimated maintenance time based on the estimated maintenance time and the current moment.

[0066] The online monitoring terminal monitors the connection status between the plum blossom moving contact and the static contact through multiple sensors, and evaluates the current connection quality of the plum blossom moving contact and the static contact based on the acquired status monitoring data, and estimates the connection status of the plum blossom moving contact and the static contact after the current moment, so that the staff can timely understand the state of reduced connection strength between the plum blossom moving contact and the static contact.

[0067] Optionally, in step S102, there is also the following processing, and the specific operation flow is as follows:

[0068] If the current temperature value is greater than or equal to the temperature threshold, a status alarm message carrying high temperature operation is generated;

[0069] If the current insertion depth value is less than or equal to the depth threshold, an alarm message carrying a shallow insertion depth is generated;

[0070] If the current clamping force value is less than or equal to the clamping force threshold, a low connection strength status alarm message is generated;

[0071] If the current temperature value is greater than the temperature threshold, the current insertion depth value is less than the depth threshold, and the current clamping force value is less than the clamping force threshold, a status warning message is generated based on the historical status monitoring data and the current status monitoring data.

[0072] During implementation, in the process of real-time reception of status monitoring data, the online monitoring management refers to the currently received status monitoring data as current status monitoring data, the previously received status monitoring data as historical status monitoring data, the clamping force value in the current status monitoring data as current clamping force value, the insertion depth value in the current status monitoring data as current insertion depth value, and the temperature value in the current status monitoring data as current temperature value.

[0073] When the online monitoring terminal compares the status threshold data with the current status monitoring data, there are at least four situations:

[0074] Case 1: If the current temperature value is greater than or equal to the temperature threshold, a status alarm message carrying high temperature operation is generated;

[0075] Case 2: If the current insertion depth value is less than or equal to the depth threshold, an alarm message carrying a shallow insertion depth is generated;

[0076] Case 3: If the current clamping force value is less than or equal to the clamping force threshold, a status alarm message of low connection strength is generated. It should be noted that when two of the above three cases exist, for example, the current temperature value is greater than or equal to the temperature threshold and the current clamping force value is less than or equal to the clamping force threshold, a status alarm message of high temperature operation and low connection strength is generated, which is similar to the above three cases.

[0077] Case 4: If the current temperature value is greater than the temperature threshold, the current insertion depth value is less than the depth threshold, and the current clamping force value is less than the clamping force threshold, a status warning message is generated.

[0078] Specifically, Figure 2 As shown, the processing method of generating status warning information is as follows:

[0079] S201, obtaining similar monitoring record data of the connection of multiple plum blossom moving contacts and static contacts of the same model and specification, wherein the similar monitoring record data includes similar clamping force change information and similar insertion depth change information.

[0080] During implementation, the online monitoring terminal obtains similar monitoring record data when multiple plum blossom moving contacts and static contacts of the same model and specification are connected. The similar monitoring record data here can come from the collection of network data or from user input.

[0081] The same type of monitoring record data at least includes the same type of clamping force change information and the same type of insertion depth change information. The same type of clamping force change information here is used to record the change value of the clamping force when the plum blossom moving contact is connected to the static contact under the same model and specification, and the same type of insertion depth change information is used to record the change value of the insertion depth when the plum blossom moving contact is connected to the static contact under the same model and specification. The multiple clamping force values ​​recorded in the same type of clamping force change information are called the same type of clamping force values, and the insertion depth values ​​in the same type of insertion depth change information are called the same type of insertion depth values.

[0082] It should be noted that when multiple plum blossom moving contacts and static contacts of the same model and specification are connected, there may still be staff performing maintenance. Therefore, in order to reduce the interference of staff maintenance on the maintenance time estimation in this application, some data after staff maintenance needs to be removed from the same type of monitoring record data.

[0083] For example, before the staff maintenance, the depth of the static contact inserted into the plum blossom moving contact is 2mm, and after the staff maintenance, the depth of the static contact inserted into the plum blossom moving contact is 2.5mm. Then, after the staff maintenance, the data of the static contact inserted into the plum blossom moving contact changes from 2.5mm to 2mm is removed from the same type of detection record data.

[0084] S202, based on the current clamping force value and the current insertion depth value, as well as a plurality of similar monitoring record data, obtain redundant quantity change information.

[0085] During implementation, the online monitoring terminal matches the same clamping force value and insertion depth value in multiple similar monitoring record data through the current clamping force value and the current insertion depth value, and then analyzes and estimates the time that the clamping force and insertion depth of the currently monitored plum blossom moving contact can be used in a safe state based on the time that can be used after the clamping force value and the insertion depth value in multiple similar monitoring record data, and uses the estimated time that can be used in a safe state as redundant change information.

[0086] S203: Generate status warning information corresponding to the clamping force value and the insertion depth value based on the redundant quantity change information.

[0087] During implementation, the online monitoring terminal uses the redundant change information and the length of time that the clamping force and the insertion depth can still be used in a safe state to generate status warning information corresponding to the clamping force value and carrying the length of time the clamping force can still be used in a safe state, and generates status warning information corresponding to the insertion depth value and carrying the length of time the insertion depth can still be used in a safe state.

[0088] The online monitoring terminal obtains the status warning information of the clamping force value and the insertion depth value, and estimates the status of the currently monitored plum blossom moving contact, so as to remind the staff to perform priority inspections and tests based on the status warning information, thereby reducing the possibility of low connection strength between the plum blossom moving contact and the static contact.

[0089] Optionally, in step S202, there is also Figure 3 The specific operation process is as follows:

[0090] S301, based on the current clamping force value and the current insertion depth value, matching corresponding target similar clamping force values ​​and target similar insertion depth values ​​in a plurality of similar monitoring record data.

[0091] During implementation, the online monitoring terminal matches the same similar clamping force value and similar insertion depth value in multiple similar monitoring record data with the current clamping value and the current insertion depth value, and the matched similar clamping force value and similar insertion depth value here are called target similar clamping force value and target similar insertion depth value.

[0092] S302, in each monitoring record data of the same type, obtain the target clamping force value of the same type and the target insertion depth value of the same type, and the corresponding clamping force redundant change time and insertion depth redundant change time.

[0093] In implementation, the online monitoring terminal uses one of the same type of monitoring record data as an example, which may be referred to herein as target same type of monitoring record data.

[0094] The online monitoring terminal captures the target clamping force value in the target monitoring record data and can still maintain safe operation for a certain period of time, which is recorded as the clamping force redundancy change period. At the same time, the online monitoring terminal captures the target insertion depth value in the target monitoring record data and can still maintain safe operation for a certain period of time, which is recorded as the insertion depth redundancy change period.

[0095] S303, generating a clamping force redundant estimated time length and an insertion depth redundant estimated time length corresponding to the currently monitored plum blossom movable contact according to a plurality of clamping force redundant change time lengths and a plurality of insertion depth redundant change time lengths.

[0096] During implementation, the online monitoring terminal summarizes multiple clamping force redundancy change durations, and can generate a clamping force redundancy estimation duration by taking an average, or a minimum, or allocating weights.

[0097] S304, summarizing and generating redundant quantity change information according to the redundant estimated time length of the clamping force and the redundant estimated time length of the insertion depth.

[0098] During implementation, the online monitoring terminal organizes and summarizes the redundant estimated time of the clamping force and the redundant estimated time of the insertion depth to generate redundant quantity change information.

[0099] Optionally, in step S303, there is also the following processing, and the specific operation flow is as follows:

[0100] Generate a clamping force redundant estimated duration according to the average of multiple clamping force redundant change durations;

[0101] The estimated insertion depth redundancy duration is generated according to the average of multiple insertion depth redundancy variation durations.

[0102] During implementation, after capturing multiple clamping force redundant change durations and multiple insertion depth redundant change durations, the online monitoring terminal calculates and generates the clamping force redundant estimated duration and the insertion depth redundant estimated duration by solving the average of the multiple clamping force redundant change durations and the average of the multiple insertion depth redundant change durations, respectively.

[0103] Optionally, in generating the status warning information, there is also the following processing, and the specific processing flow is as follows:

[0104] Obtain the current value flowing at the connection between the plum blossom moving contact and the static contact in real time;

[0105] Receive the power temperature rise data table of the plum blossom moving contact input by the user or obtained from the specified network address, the power temperature rise data table is used to reflect the corresponding stable temperature values ​​under multiple power distribution intervals;

[0106] Match the corresponding target stable temperature value in the temperature rise data table according to the current flowing current value;

[0107] If the difference between the current temperature value and the target stable temperature value is greater than the preset temperature difference, an excessive temperature rise status warning message is generated.

[0108] In implementation, the online monitoring terminal receives the user input, or obtains the power temperature rise data table of the plum blossom moving contact from a specified network address. The temperature rise data of the plum blossom moving contact is divided into multiple power distribution intervals, and each power distribution interval corresponds to a stable temperature value, which is used to reflect whether the maximum amount of current that can flow through the plum blossom moving contact is reduced. At the same time, since the voltage in the transmission line is usually stable and unchanged, each power distribution interval corresponds to a current distribution interval.

[0109] The online monitoring terminal receives in real time the current value flowing at the connection between the plum blossom moving contact and the static contact, which is referred to as the flowing current value.

[0110] The online monitoring terminal matches the corresponding current distribution interval and the stable temperature rise value in the temperature rise data table with the currently received circulating current value. The matched stable temperature rise value is called the target stable temperature rise value.

[0111] Then, if the current temperature value is greater than the target stable temperature value, and the difference between the current temperature value and the target stable temperature value is greater than the preset temperature difference, the online monitoring terminal generates a status warning message of excessive temperature rise.

[0112] Optionally, in step S103, there is also the following processing, and the specific operation flow is as follows:

[0113] The first maintenance estimate time and the second maintenance estimate time are calculated and generated according to the redundant estimated time of the clamping force, the redundant estimated time of the insertion depth and the preset advance maintenance time;

[0114] An estimated maintenance time is generated based on the first maintenance estimated duration, the second maintenance estimated duration and the preset maintenance cycle duration.

[0115] During implementation, the online monitoring terminal subtracts the preset advance maintenance time from the redundant estimated time of the clamping force and the redundant estimated time of the insertion depth, respectively, to generate the first maintenance estimated time and the second maintenance estimated time.

[0116] Then the online monitoring terminal selects the shortest of the first maintenance estimated duration, the second maintenance estimated duration and the preset maintenance cycle duration as the estimated maintenance duration. Then the online monitoring terminal adds the estimated maintenance duration to the current time to calculate and generate the estimated maintenance time.
