[0040] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0041] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0042] See also Figure 2In an embodiment of the present invention, an intelligent monitoring method for erecting a high-voltage cable is provided. An overhead cable is fixed on an overhead pole. The high-voltage cable is connected to the overhead cable through a plurality of hooks distributed at intervals. Sensors are arranged on the hooks. The method comprises the following steps:

[0043] The swing amplitude data and the tension data detected by each of the sensors are received, and a judgment is made on whether the installed high-voltage cable is abnormal based on each of the swing amplitude data and the tension data.

[0044] On the basis of the prior art, the present invention arranges a sensor on the lifting hook of the high-voltage cable, which can detect the swing amplitude data and tension data of the corresponding position, compare the above data with the corresponding judgment threshold, and then determine whether the installed high-voltage cable is abnormal according to the corresponding comparison result. The solution of the present invention does not require maintenance personnel to detect whether the high-voltage cable is abnormal through on-site inspections, and can identify the abnormal situation of the high-voltage cable in advance, so that relevant personnel can be dispatched in time for on-site disposal. Compared with the existing method that can only be identified after the high-voltage cable is damaged or even broken due to external force, it has obvious progress and beneficial effects.

[0045] The above-mentioned sensor is a composite sensor, which includes a first sensor module capable of measuring swing amplitude data and a second sensor module capable of measuring tension data. The first sensor module may be a gyroscope or a magnetic sensor (determining the swing amplitude by detecting changes in magnetic variables), and the second sensor module is a tension sensor.

[0046] In addition, a processor for processing and analyzing the above data to implement the above and subsequent methods of the present invention should also be arranged, which can be arranged on an overhead pole. The processor is connected to the sensors, alarms, communication antennas, etc. involved by wire or wirelessly.

[0047] Preferably, at least one of the hooks is provided with an audio detector; the step of receiving the swing amplitude data and the tension data detected by each of the sensors comprises:

[0048] receiving sound data of a passing object detected by the audio detector;

[0049] predicting a first height of the passing object based on the sound data and comparing the first height to a second height of a target location of the high voltage cable between adjacent overhead poles;

[0050] If the height difference between the second height and the first height is smaller than a preset value, each of the sensors is activated, and the swing amplitude data and the tension data detected by each of the sensors are received.

[0051] In an embodiment of the present invention, the present invention pre-arranges a periodic start-up working mechanism, based on which the sensor can be controlled to work intermittently, thereby effectively reducing the invalid detection of the sensor arranged on the hook and reducing power consumption. At the same time, in order to avoid missing the detection of abnormal situations, the present invention also arranges an audio detector on at least part of the hook, which can detect the sound data of the object passing through the section of high-voltage cable, based on which the first height of the passing object can be inferred, and it is compared with the second height of the target position of the section of high-voltage cable. If it is close or even exceeds, it means that the passing object may touch the section of high-voltage cable, and the sensor needs to be started for abnormal monitoring; otherwise, it means that the passing object is unlikely to touch the section of high-voltage cable, and there is no need to start the sensor. Therefore, on the basis of the above-mentioned periodic start-up working mechanism, the present invention also sets a trigger mechanism. Through the combination of the two working mechanisms, a balance can be achieved between accurate detection and reduced power consumption.

[0052] The target position of the high-voltage cable refers to the lowest position of the section of the high-voltage cable, or the lowest position of the section of the high-voltage cable located above the road.

[0053] Preferably, predicting the first height of the passing object according to the sound data comprises:

[0054] Extracting volume data and audio data from the sound data, and identifying the passing object as a first type or a second type according to the volume data; wherein the first type is a vehicle type and the second type is a non-vehicle type;

[0055] If the passing object is of the first type, the passing object is further identified as a light vehicle or a heavy vehicle based on the proportion of the low-frequency part and the high-frequency part in the audio data, and the first height of the light vehicle or the heavy vehicle is determined by query.

[0056] In an embodiment of the present invention, the sound data collected by the audio detector includes sound volume and sound audio features. Based on the sound volume, pedestrian objects, non-motor vehicle objects and motor vehicle objects (mainly motor vehicles using internal combustion engine power) passing through the high-voltage cable can be easily distinguished and identified, because the sound volume emitted by motor vehicle objects (i.e., the first type) and pedestrian objects and non-motor vehicle objects (i.e., the second type) is significantly different. Then, the light vehicles and heavy vehicles in the motor vehicles are distinguished and identified according to the sound audio features, and the types of passing objects are divided. There is a clear difference between the heights of light vehicles (such as motorcycles, ordinary cars) and heavy vehicles (trucks, buses, muck trucks, etc.). The height of heavy vehicles is generally significantly higher than that of light vehicles, and there is a greater probability of touching the section of high-voltage cable. The first height corresponding to light vehicles and heavy vehicles is pre-set, and the highest vehicle height of all vehicles belonging to light vehicles and heavy vehicles is generally determined as the above-mentioned first height.

[0057] Generally, the engine sound frequency of light vehicles is mainly concentrated between 100-3000Hz, while for heavy vehicles, due to their larger engine size and stronger power, the composition of their sound frequency is significantly different from that of light vehicles, which is mainly reflected in the fact that they are more inclined to the low-frequency part. Therefore, the present invention identifies whether the passing object is a light vehicle or a heavy vehicle based on the proportion of the low-frequency part and the high-frequency part in the collected audio data, that is, if the proportion of the low-frequency part in the collected audio data is higher, it is determined to be a light vehicle, and if the proportion of the high-frequency part in the collected audio data is higher, it is determined to be a heavy vehicle.

[0058] Preferably, the identifying the passing object as a light vehicle or a heavy vehicle according to the proportion of the low-frequency part and the high-frequency part in the audio data comprises:

[0059] Calculating the difference between the proportions of the low-frequency part and the high-frequency part in the audio data;

[0060] If the difference is higher than a first threshold, then: if the high-frequency portion of the collected audio data accounts for a higher proportion, the passing object is identified as a light vehicle; if the low-frequency portion of the collected audio data accounts for a higher proportion, the passing object is identified as a heavy vehicle;

[0061] If the difference is lower than the first threshold, then: calculate the audio fluctuation amplitude of the high-frequency part of the audio data; if the audio fluctuation amplitude is higher than the second threshold, identify the passing object as a heavy vehicle; otherwise, identify the passing object as a light vehicle.

[0062] In the embodiment of the present invention, the above method distinguishes whether the passing object is a light vehicle or a heavy vehicle based on the proportion of the high-frequency part and the low-frequency part in the audio data. However, when the displacement of the light vehicle is large, the load is small, and the gear is low, the proportion of its low-frequency part will increase appropriately. At this time, there may be a certain overlap with the proportion of the low-frequency part of the heavy vehicle (especially the unloaded lightweight heavy vehicle), which may easily lead to misidentification. In this regard, the present invention further analyzes the audio fluctuation amplitude of the high-frequency part in the audio data. Due to the working environment and load requirements of the heavy vehicle, the audio fluctuation amplitude of its engine will be significantly higher than that of the light vehicle, thereby realizing further identification of light vehicles and heavy vehicles.

[0063] Preferably, judging whether the installed high-voltage cable is abnormal based on the swing amplitude data and the tension data includes:

[0064] Calculate the deviation between each of the swing amplitude data and the corresponding reference swing amplitude data to obtain a plurality of swing amplitude deviation data, and use the average value of each of the swing amplitude deviation data as the swing evaluation value;

[0065] If the swing evaluation value is higher than the third threshold, then:

[0066] The tension deviation data of the adjacent tension data are calculated. If any of the tension deviation data is N times higher than the other tension deviation data, it is determined that there is an abnormality in the installed high-voltage cable. Otherwise, it is determined that there is no abnormality in the installed high-voltage cable.

[0067] In an embodiment of the present invention, due to the presence of wind, the first sensor module capable of measuring swing amplitude data and the second sensor module capable of measuring tension data can respectively measure swing amplitude data and tension data of certain values. In order to reduce the normal swing of the high-voltage cable under the action of wind, the swing data under the wind of the current cycle is pre-determined as the reference swing amplitude data. When in use, the swing amplitude data detected by each first sensor module is first calculated with the corresponding reference swing amplitude data for deviation, and then the average value of each swing amplitude deviation data obtained by the deviation calculation is summed up as the swing evaluation value, and the swing evaluation value represents the swing amplitude of the high-voltage cable. If the swing evaluation value is lower than the third threshold value, it means that there is no abnormality in the swing of the high-voltage cable; if the swing evaluation value is higher than the third threshold value, it means that there is an abnormality in the swing of the high-voltage cable.

[0068] At the same time, the "abnormality" of the swing evaluation value being higher than the third threshold may be caused by a sudden increase in wind force. In this regard, the present invention further calculates the tension deviation data between adjacent tension data (i.e., the absolute value of the difference between the detection data of adjacent second sensor modules). If any tension deviation data is significantly higher than other tension deviation data and reaches N times (N can be 1.3-1.7), it is highly likely that the high-voltage cable between the two adjacent hooks is subjected to a large tension (for example, the upper edge of a heavy vehicle hangs on the high-voltage cable). At this time, it can be determined that there is an abnormality in the erected high-voltage cable, otherwise it is determined that the tension is increased due to the centrifugal force during the swing under the action of wind.

[0069] It should be noted that since the hook only provides a hanging point for the high-voltage cable, the two are not fixedly connected. Therefore, when a section of the high-voltage cable is hung by the upper edge of a heavy vehicle, the high-voltage cables in other sections will move to a certain extent toward the hanging section, causing the length of the high-voltage cable in the hanging section to become longer. The corresponding tension deviation data (i.e., the tension deviation data between the second sensor modules at both ends of the hanging section and the upstream second sensor module on the side close to the overhead pole) will increase significantly. At this time, it can be determined that an abnormality exists.

[0070] Preferably, the reference swing amplitude data is determined by:

[0071] The reference swing amplitude data is determined based on the distance between the corresponding sensor and one side of the overhead pole, and the greater the distance, the greater the reference swing amplitude data, and vice versa.

[0072] In the embodiment of the present invention, since the wind generally does not blow vertically toward the high-voltage cable, the wind force on each section of the high-voltage cable is different to a certain extent. In view of this, the present invention is configured to determine its own reference swing amplitude data according to the normal swing data of each first sensor module when there is no abnormality in the current cycle, so that the swing amplitude deviation data calculated can better reflect the actual situation.

[0073] See also Figure 3 The present invention also discloses that the present invention also provides a high-voltage cable intelligent monitoring system, the system comprising a plurality of hooks with sensors, a processor, a memory, an alarm and a communication antenna; wherein the aerial cable is fixed on the aerial pole, and the high-voltage cable is connected to the aerial cable through a plurality of hooks distributed at intervals;

[0074] Each of the sensors is used to detect the swing amplitude data and tension data of the high-voltage cable and transmit the data to the processor;

[0075] An audio detector is arranged on at least one of the hooks, and the audio detector is used to detect sound data of a passing object and transmit it to the processor;

[0076] The memory is used to store computer program code;

[0077] The processor is used to call the computer program code stored in the memory to implement any of the methods described above, and when it is determined that there is an abnormality in the high-voltage cable, an alarm is issued through the alarm and / or the communication antenna.

[0078] Among them, the alarm is used to alert over-height vehicles on site, and the communication antenna is connected to the background server to transmit relevant alarm signals back when there is an abnormality, assisting the background server to dispatch relevant personnel to come for inspection and repair.
