[0077] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with 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 intended to limit the present invention.
[0078] Figure 1The flowchart of the method for real-time monitoring of the grounding point hanging wire state based on pressure is shown in the embodiment of the present invention. The method for real-time monitoring of the grounding point hanging wire state based on pressure includes:
[0079] Step S100: obtaining an operation map, querying facility filing information and operation videos, and determining a work area in the operation map according to the facility filing information and operation videos;
[0080] The technical solution of the present invention is used for work scenes, and the map of the work scene is easy to obtain. In practical applications, the map is necessary data, and for the present invention, it can be directly read; after obtaining the work map, the registered facilities and work videos are queried. The registered facilities are mainly working equipment in the work scene, which actually determines the work station of the staff. The work video is the movement of the staff during the actual work process. By combining these two types of data, a personnel activity area can be determined in the work area, which is called the work area.
[0081] Step S200: acquiring the power network of the work area, inserting the power network into the work map, and determining the risk value of each location in the work area based on the power network;
[0082] The power lines in the operation area are called power networks. The power networks are inserted into the operation map to obtain the operation map containing power lines. The risk level of each location in the entire operation area can be determined based on the power lines, which is represented by the risk value parameter in the operation map. Generally speaking, the closer to the power lines, the greater the risk value.
[0083] Step S300: obtaining the position information of the grounding wire clamping mechanism, matching the grounding point in the power network, judging the grounding state based on the pressure sensor built into the grounding wire clamping mechanism, and generating a safety layer containing a safety value;
[0084] The grounding wire clamping mechanism mentioned in the present application is an active grounding device, which is used to clamp the wires and then connect the power. A pressure sensor is built into the grounding wire clamping mechanism to detect the pressure and upload it to the execution platform of the present method. The execution platform of the present method can determine whether the grounding wire clamping mechanism clamps the line, and then determine whether it is grounded; in this process, the data upload process of the pressure sensor is intermittent, which is used to provide endurance; 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 high. If the data is uploaded in real time, although the data integrity is high, the endurance is short. From a safety perspective, there is a greater risk, because there is a risk when replenishing resources (changing batteries). If the batteries are not changed, the data is completely missing, which also poses a risk.
[0085] Furthermore, after obtaining the pressure detection data of the pressure sensor, the pressure detection data is analyzed to determine whether the grounding wire clamping mechanism is in a clamping state. This state is a zero-one state, either in a clamping state or not in a clamping state. The zero-one 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 zero-one state needs to be reflected in the operation map. Therefore, the present application generates a safety layer containing a safety value 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: superimposing the safety layer onto the operation map containing the risk value, and displaying the operation map in real time;
[0087] The safety layer is superimposed on the operation map containing risk values and displayed in real time. Viewers can understand the risk status of the entire area through the operation map. It is worth mentioning that the superposition process of the safety layer generally adopts a reduction process, that is, the value in the safety layer belongs to a negative risk value, which is used to reduce the original risk value when superimposed.
[0088] As a preferred embodiment of the technical solution of the present invention, for each grounding point, the judgment result of the grounding state is recorded, and the judgment frequency of the grounding state of each grounding point is adjusted according to the judgment result.
[0089] Among them, since the grounding state is a zero-one state, either zero or one, the judgment result is actually a zero-one array, each element corresponds to a judgment result, and a simple analysis of the judgment result can determine the judgment frequency; it is worth mentioning that, assuming that when it is not in a compressed 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 a compressed state, the higher the judgment frequency.
[0090] Figure 2 The first sub-process flowchart of the method for real-time monitoring of the grounding point hanging wire status based on pressure, wherein the steps of obtaining the operation map, querying the facility filing information and the operation video, and determining the working area in the operation map according to the facility filing information and the operation video include:
[0091] Step S101: obtaining a work map;
[0092] Step S102: Establishing a connection channel with the filing database to query facility filing information;
[0093] Step S103: establishing a connection channel with a video database to query the operation video;
[0094] Step S104: determining the work location in the operation map based on the facility filing information, and determining the historical personnel distribution location based on the operation video;
[0095] Step S105: Determine the work area based on the work location and historical personnel distribution locations.
[0096] The above content limits the process of determining the work area. The work map is the default known data and can be obtained directly. Then, the registered equipment information and work video can be queried. The equipment information can determine the work location, and the work video can determine the personnel distribution location (the area extended based on the activity trajectory of the staff). With the work location as the center, a circular area is determined, and then its union with the personnel distribution location is calculated to obtain the final work area.
[0097] Among them, the activity trajectory of the staff can be obtained using the existing video tracking algorithm.
[0098] Figure 3 The second sub-process flowchart of the method for real-time monitoring of the grounding point hanging wire status based on pressure, wherein the steps of obtaining the power network in the working area, inserting the power network into the working map, and determining the risk value of each location in the working area based on the power network include:
[0099] Step S201: Acquire the power network of the operation area, and insert the power network into the operation map based on the scale of the operation map;
[0100] Step S202: obtaining the working current of each line in the power network, and determining the basic risk value of each line according to the working current;
[0101] Step S203: determining the risk value of each location in the working area according to the basic risk value;
[0102] The rules are determined as follows:
[0103] ; In the formula, For location The risk value at For the The basic risk value corresponding to the line, Indicates the total number of lines. It's location With The distance between the lines.
[0104] The above content explains the calculation process of the risk value. The wiring information of the working area is obtained, which is called the power network. The power network is inserted into the working map according to the scale of the working map. The insertion method is generally to draw lines corresponding to the power network in the working map; then, the working current of each line in the power network is obtained. In a normal and stable production process, the working current will basically not change because the line itself will not be adjusted significantly; after obtaining the working current of each line, the basic risk value of each line can be determined based on the working current. The larger the working current, the higher the basic risk value; finally, according to the basic risk value of each line, the risk value at each location in the working area can be finally determined.
[0105] The rule for determining the risk value is that, for a certain location, the risk value of all lines at that location is calculated, which is proportional to the current of the line and inversely proportional to the distance.
[0106] Figure 4 The third sub-flow chart of the method for real-time monitoring of the grounding point hanging wire state based on pressure, wherein the steps of obtaining the position information of the grounding wire clamping mechanism, matching the grounding point in the power network, judging the grounding state based on the pressure sensor built into the grounding wire clamping mechanism, and generating a safety layer containing a safety value include:
[0107] Step S301: acquiring position information based on a positioner built into the ground wire clamping mechanism;
[0108] Step S302: querying the map coordinates corresponding to the location information in the operation map;
[0109] Step S303: querying the point in the power network that is closest to the map coordinates as the grounding point;
[0110] Step S304: obtaining the pressure of the pressure sensor built into the ground wire pressing mechanism, and comparing it with a preset pressure range;
[0111] Step S305: Generate a security layer containing a security value based on the comparison result;
[0112] Wherein, the security layer is:
[0113] ; In the formula, Indicates the judgment result at the grounding point. When the pressure is within the pressure range, the judgment result is one. When the pressure is not within the pressure range, the judgment result is zero. Indicates the coordinates of any point in the security layer relative to the ground point. express The safety value at are the preset parameters.
[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 inputs an update interval in advance. The operation map is updated every time an update interval passes. The updating method is to obtain all the safety layers generated within the update interval, superimpose them all on the current operation map, and obtain the updated operation map.
[0123] The superposition process is very simple. What needs to be explained is 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 status;
[0126] Starting from the tail data of the recorded judgment result, reversely intercept a preset amount of data;
[0127] Determine the judgment frequency of the grounding point based on the intercepted data;
[0128] The process of determining the frequency is:
[0129] ; In the formula, Indicates the judgment frequency, is the number of zero data in the reverse truncated data, is the preset quantity, is a preset constant.
[0130] The judgment frequency is positively correlated with the proportion of zero data. The greater the number of zero data, the more data that does not fall within the pressure range, which means that there are more risk situations. At this time, the judgment frequency should be increased.
[0131] The above content provides a specific solution 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 an array of zeros and ones. When the pressure does not fall within the pressure range, the judgment result is zero. Based on this, starting from the tail data of the recorded judgment result, reverse forward to obtain a preset number of data, calculate the number of zeros, and determine the judgment frequency.
[0132] The preset number means that the acquired data is limited to a certain time range, such as one day, to ensure the real-time nature of the data.
