Description

[0002] Safely installing the grounding wire is an important technical measure to ensure personal, equipment, and power grid safety. It can prevent human injuries caused by sudden power-on. With the continuous deepening of power grid construction, the power grid system has become increasingly complex. Temporary grounding wires are frequently used and scattered during operation. Traditional portable short-circuit grounding wires lack intelligent monitoring means and management systems, and are prone to problems such as missing hanging, wrong hanging, and missing removal during use, posing great safety hazards. The portable short-circuit grounding wire is the lifeline to ensure the personal safety of staff and a safety barrier to protect maintenance personnel, which can prevent human injuries caused by sudden power-on, and its importance is self-evident.

That is, when a problem with the pressure is detected, an alarm message is generated.

[0077] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0078] Figure 1It is a flowchart of a real-time monitoring method for the grounding wire connection status based on pressure. In an embodiment of the present invention, a real-time monitoring method for the grounding wire connection status based on pressure, the method includes:

[0079] Step S100: Obtain an operation map, query the facility filing information and operation video, and determine the working area in the operation map according to the facility filing information and operation video;

[0080] The technical solution of the present invention is used in an operation scenario. The map of the operation scenario is easily obtained. In practical applications, the map is necessary data and can be directly read for the present invention; after obtaining the operation map, query the filed facilities and operation video. The filed facilities are mainly the working equipment in the operation scenario, which actually determines the workstations of the staff. The operation video shows the movement of the staff during the actual work. Combining these two types of data, a personnel activity area can be determined in the operation area, which is called the working area.

[0081] Step S200: Obtain the power network of the operation area, insert the power network into the operation map, and determine the risk values of each position in the working area based on the power network;

[0082] Obtain the power lines in the operation area, which is called the power network. Insert the power network into the operation map to obtain an operation map containing power lines. Based on the power lines, the risk levels of each position in the entire operation area can be determined and represented by the parameter of risk value in the operation map; generally, the closer to the power line, the greater the risk value.

[0083] Step S300: Obtain the position information of the grounding wire clamping mechanism, match the grounding point in the power network, judge the grounding status based on the pressure sensor built in the grounding wire clamping mechanism, and generate a safety layer containing safety values;

[0084] The grounding wire clamping mechanism mentioned in this application is a movable grounding device. The grounding wire clamping mechanism is used to clamp the wire and then connect the power. A pressure sensor is built in the grounding wire clamping mechanism to detect the pressure and upload it to the execution platform of this method. The execution platform of this method can judge whether the grounding wire clamping mechanism clamps the line, and then judge whether it is grounded; in this process, the data upload process of the pressure sensor is intermittent to provide battery life; for the grounding wire clamping mechanism, the resource consumption for obtaining pressure is not high, but the resource consumption in the data transmission process is relatively high. If the data is uploaded in real time, although the data integrity is high, the battery life is short. From a safety perspective, there is actually a greater risk because there is a risk when replenishing resources (changing the battery). If the battery is not changed, then the data is completely missing, which also poses a risk.

[0085] Further, after obtaining the pressure detection data of the pressure sensor, analyzing the pressure detection data can determine whether the grounding wire pressing mechanism is in a pressed state. This state is a binary state, either in the pressed state or not in the pressed state. This binary state needs to be integrated with the operation map so that the output of the technical solution of the present invention is completely a single operation map. In other words, the binary state needs to be reflected in the operation map. Therefore, the present application generates a safety layer containing safety values based on the judgment result and inserts the safety layer into the operation map, so that the output of the execution subject of this method is the final map.

[0086] Step S400: Superimpose the safety layer on the operation map containing risk values and display the operation map in real time;

[0087] Superimposing the safety layer on the operation map containing risk values and simultaneously displaying it in real time, viewers can understand the risk status of the entire area through the operation map. It is worth mentioning that the superimposing process of the safety layer generally adopts a subtraction process, that is, the values in the safety layer belong to negative risk values, and when superimposing, they are used to reduce the original risk values.

[0088] As a preferred embodiment of the technical solution of the present invention, for each grounding point, record the judgment result of the grounding state and adjust the judgment frequency of the grounding state of each grounding point according to the judgment result.

[0089] Among them, since the grounding state is a binary state, either zero or one, the judgment result is actually a binary array, and each element corresponds to a judgment result. By simply analyzing the judgment result, the judgment frequency can be determined. It is worth mentioning that assuming that when it is not in the pressed state, the corresponding element is zero, then the judgment frequency can be directly proportional to the number of zeros, that is, the more times it is not in the pressed state, the higher the judgment frequency.

[0090] Figure 2 It is the first sub-process block diagram of the real-time monitoring method for the hanging wire state of the grounding point based on pressure. The steps of obtaining the operation map, querying the facility record information and the operation video, and determining the working area in the operation map according to the facility record information and the operation video include:

[0091] Step S101: Obtain the operation map;

[0092] Step S102: Establish a connection channel with the record database and query the facility record information;

[0093] Step S103: Establish a connection channel with the video database and query the operation video;

[0094] Step S104: Determine the working position in the operation map based on the facility record information and determine the historical personnel distribution position based on the operation video;

[0095] Step S105: Determine the working area based on the working position and the historical personnel distribution position.

[0096] The above content defines the process of determining the working area. The operation map belongs to the default known data and can be directly obtained. Then, query the recorded device information and operation videos. The device information can determine the working position, and the operation videos can determine the personnel distribution position (the area extended based on the activity trajectories of the staff). Taking the working position as the center, determine a circular area, and then calculate the union of it and the personnel distribution position to obtain the final working area.

[0097] Among them, the activity trajectories of the staff can be obtained by using existing video tracking algorithms.

[0098] Figure 3 It is the second sub-process block diagram of the real-time monitoring method for the grounding wire hanging state based on pressure. The steps of obtaining the power grid of the operation area, inserting the power grid into the operation map, and determining the risk values of each position in the working area based on the power grid include:

[0099] Step S201: Obtain the power grid of the operation area and insert the power grid into the operation map based on the scale of the operation map;

[0100] Step S202: Obtain the working current of each line in the power grid and determine the basic risk value of each line according to the working current;

[0101] Step S203: Determine the risk values of each position in the working area according to the basic risk values;

[0102] The determination rule is:

[0103] ; where is the risk value at position , is the basic risk value corresponding to the th line, represents the total number of lines, is the distance between position and the th line.

[0104] The above content describes the calculation process of the risk value. First, obtain the wiring information of the operation area, which is called the power network. Then, insert the power network into the operation map according to the scale of the operation map. Generally, the insertion method is to draw lines corresponding to the power network in the operation map. Next, obtain the working current of each line in the power network. During normal and stable production, the working current basically does not change because there are no major adjustments to the lines themselves. After obtaining the working current of each line, the basic risk value of each line can be determined based on the working current. The greater the working current, the higher the basic risk value. Finally, based on the basic risk value of each line, the risk value at each position within the working area can be ultimately determined.

[0105] The rule for determining the risk value is that for a certain position, calculate the risk values of all lines at that position, which is directly proportional to the current of the line and inversely proportional to the distance.

[0106] Figure 4 It is the third sub - process block diagram of the real - time monitoring method for the grounding wire hanging state based on pressure. The steps of obtaining the position information of the grounding wire pressing mechanism, matching the grounding point in the power network, and judging the grounding state based on the pressure sensor built into the grounding wire pressing mechanism to generate a safety layer containing safety values include:

[0107] Step S301: Obtain the position information based on the locator built into the grounding wire pressing mechanism;

[0108] Step S302: Query the map coordinates corresponding to the position information in the operation map;

[0109] Step S303: Query the point in the power network that is closest to the map coordinates as the grounding point;

[0110] Step S304: Obtain the pressure of the pressure sensor built into the grounding wire pressing mechanism and compare it with the preset pressure range;

[0111] Step S305: Generate a safety layer containing safety values based on the comparison result;

[0112] Among them, the safety layer is:

[0113] ; In the formula, represents the judgment result at the grounding point. When the pressure belongs to the pressure range, the judgment result is one; when the pressure does not belong to the pressure range, the judgment result is zero. represents the coordinates of any point in the safety layer relative to the grounding point. represents the safety value at is a preset parameter.

[0114] In the technical solution of the present invention, a locator is also installed in the grounding wire clamping mechanism, and its position information can be obtained by the locator. The map coordinates corresponding to the position information can be queried in the operation map. Since the grounding wire clamping mechanism is installed on the line, its map coordinates will also overlap with the power network. However, in actual situations, there are certain errors. For this, the present application queries the point in the power network that is closest to the map coordinates as the grounding point to eliminate this error.

[0115] Then, obtain the pressure of the pressure sensor built into the ground wire clamping mechanism. Since the collection results of the pressure sensor are highly volatile and basically not fixed, the higher the accuracy, the more drastic the fluctuation, but they will all be within a certain range. Therefore, compare the obtained collection results with the preset pressure range, and generate a safety layer based on the comparison results.

[0116] The safety layer is the safety layer of each grounding point. The weights of each point around the grounding point are determined based on the Gaussian kernel. The safety value of the point can be obtained by multiplying the weight by the judgment result at the grounding point. When the judgment result is one, it means that the pressure belongs to the pressure range. At this time, there will be a safety value. The safety value is a negative number and is used to superimpose the original risk value to reduce the risk value. Therefore, it is called the safety value. If the judgment result is zero, it means that the pressure does not belong to the pressure range. At this time, the risk is still very high, the safety value is zero, and the risk value does not decrease.

[0117] Figure 5 The fourth sub-flow chart of the method for real-time monitoring of the grounding point hanging wire status based on pressure, wherein the step of superimposing the safety layer on the operation map containing the risk value and displaying the operation map in real time includes:

[0118] Step S401: receiving the update interval input by the administrator, and obtaining all security layers generated within the update interval;

[0119] Step S402: superimposing all safety layers onto the operation map containing the risk value;

[0120] The superposition process is:

[0121] ; In the formula, Indicate point The superimposed value at Indicates Grounding point at The safety value at is the total number of security layers.

[0122] The administrator pre-enters an update interval. Every time an update interval elapses, the operation map is updated. The update method is to obtain all the security layers generated within the update interval and overlay them all on the current operation map to obtain the updated operation map.

[0123] The overlay process is very simple. It should be noted that the same point may correspond to multiple security layers.

[0124] As a preferred embodiment of the technical solution of the present invention, the content of recording the judgment result of the grounding state for each grounding point and adjusting the judgment frequency of the grounding state of each grounding point according to the judgment result includes:

[0125] For each grounding point, record the judgment result of the grounding state;

[0126] Starting from the tail data of the recorded judgment results, reverse intercept a preset number of data;

[0127] Determine the judgment frequency of the grounding point according to the intercepted data;

[0128] The process of determining the judgment frequency is as follows:

[0129] ; where represents the judgment frequency, is the number of data that are zero in the reverse-intercepted data, is the preset number, is a preset constant.

[0130] The judgment frequency is positively correlated with the proportion of the number of data that are zero. The larger the number of data that are zero, the more data indicating that the pressure does not belong to the pressure range, indicating that more risk situations have occurred. At this time, increase the judgment frequency.

[0131] The above content provides a specific scheme for updating the judgment frequency of the grounding point. For the judgment result of each grounding point, it can be known from the above content that the recorded judgment result is a zero-one array. When the pressure does not belong to the pressure range, the judgment result is zero. Based on this, starting from the tail data of the recorded judgment results, reverse deduce forward to obtain a preset number of data, and calculate how many zeros there are to determine the judgment frequency.

[0132] Among them, the meaning of the preset number is to limit the obtained data within a certain time range, such as within one day, to ensure the real-time nature of the data.
