Description

Technical Field

[0001] The invention belongs to the technical field of street lamp tilt detection, and in particular relates to a street lamp pole tilt detection method. Background Art

[0002] Street lights are the most basic lighting tools. Street lights are basically set up outdoors. Because they are set up outdoors, they are prone to natural or man-made damage. For example, strong winds, vehicle collisions, etc. can easily cause street light poles to tilt or even collapse. In addition, since street light poles are usually more than ten meters high, if they are not discovered in time, once the street light poles tilt and tilt to a certain extent, they will cause circuit breakage and fire, which may cause large-scale power outages, and the collapse will also cause harm to pedestrians or buildings such as houses. Reports on the tilting of street light poles are also common. For example, see Figure 1 On April 21, the wind gusts in a certain city reached level 5 to 6. The strong wind caused a street lamp pole at the south end of the Puhe Bridge to tilt to one side, posing a safety hazard to passers-by.

[0003] In order to detect the tilt of street light poles, the prior art uses a level, a gyroscope, etc. to detect whether the street light pole is tilted, and the level and other detection devices feed back data to the management system through the communication module in the street light, so as to take necessary preventive measures to avoid serious accidents caused by the collapse of street light poles. However, because the location where the street light is installed cannot be horizontal, it may be on a slope, or the design of the street light in a specific scene may not be perpendicular to the ground. Therefore, the prior art has proposed other detection schemes, such as acceleration sensors (see CN217116469U), tilt sensors (see CN107909769A), etc., and proposed corresponding detection methods.

[0004] For example, Chinese invention patent application CN112629495A discloses a method for detecting the tilt of a street lamp, which proposes to install a three-axis acceleration sensor on the street lamp, so as to determine whether the tilt occurs through the three-axis acceleration data. Specifically, it collects the three-axis acceleration data of multiple groups of street lamps, and then performs digital filtering on the three-axis acceleration data of the multiple groups of street lamps, and obtains the current three-axis acceleration data as the current three-dimensional vector, and then calculates the vector angle between the current three-dimensional vector and the zero-degree three-dimensional vector, and finally obtains the tilt angle of the street lamp according to the vector angle; it solves the problem of street lamp tilt detection in any application scenario.

[0005] For another example, Chinese invention patent application CN105590418A discloses a street light pole tilt detection alarm method and system, which detects the tilt angle of the street light pole through a tilt detection device installed on the street light pole, and then sends the tilt angle to a remote communication device, which sends it to a monitoring center. Thus, the monitoring center can remotely and in real time understand the tilt angles of street light poles distributed in various geographical locations, and the monitoring center can automatically display the information of street light poles whose tilt angles are greater than a preset tilt threshold value, so as to serve as an alarm prompt.

[0006] It can be seen that the existing street lamp pole detection methods mostly compare the tilt data detected by each street lamp with the preset tilt angle threshold, and issue an early warning if the threshold is reached. However, the tilt of the lamp pole is not an instantaneous process, but a continuous process. For example, an external force impact causes the lamp pole to shake greatly in a short period of time, but it does not tilt in the end, but only tilts slightly. Therefore, if an early warning is issued once the tilt angle reaches the preset threshold at any time, the probability of false alarms is greatly increased. Summary of the invention

[0007] The object of the present invention is to provide a method for detecting the inclination of a street lamp pole, which partially solves or alleviates the above-mentioned deficiencies in the prior art, can perform low-cost inclination detection of a street lamp group, and effectively avoids false alarms.

[0008] In order to solve the above-mentioned technical problems, the present invention specifically adopts the following technical solutions: A method for detecting the inclination of a street lamp pole is provided. A plurality of street lamps located on the same road section are divided into a group. Each street lamp group includes a first lamp pole and a plurality of second lamp poles. A first sensor is provided at the top and the bottom of the first lamp pole, and a second sensor is provided at the bottom of the second lamp pole. The second sensor can only qualitatively detect the inclination of the lamp pole, while the first sensor can both qualitatively detect the inclination of the lamp pole and quantitatively detect the inclination angle of the lamp pole. Accordingly, the method includes the steps of: S101 collects first tilt angle data collected by the first sensor at the top of the first lamp pole, and determines whether tilt occurs. If so, execute step S103; otherwise, execute step S105; S103 determines whether the tilt state of the first lamp pole continues within the first preset time T1, and if so, executes step S107; otherwise, continues monitoring; S105 determines that the first lamp pole is currently temporarily tilted and continues monitoring; S107: obtaining the second tilt angle data collected by the first sensor at the bottom of the first lamp pole, and combining the first tilt angle data and the second tilt angle data to determine whether the first lamp pole is tilted, if tilted, executing step S109, otherwise continue monitoring; S109: Obtaining the tilt state data collected by the second sensor on the top of the second lamp pole, and determining the tilt condition of the second lamp pole according to the tilt state data.

[0009] As an improvement, the step of determining the tilt using the first tilt angle data in step S101 includes: If the first tilt angle data α1> the top threshold angle α T , it is determined that the top of the first lamp pole is tilted and the first lamp pole is marked as a continuous monitoring state; the first lamp pole marked as a continuous monitoring state increases the density of collected data.

[0010] As an improvement, the step of determining whether the tilt state of the first lamp pole continues within the first preset time T1 in step S103 includes: If the first inclination angle data α1 of the lamp post is greater than the continuous threshold angle α within the first preset time T1, L , it is determined that the top of the first lamp pole is continuously tilted and the street lamp is marked as a first-level warning state; wherein the continuous threshold angle α L <Top threshold angle α T .

[0011] As an improvement, the step of determining whether the tilt state of the first lamp pole continues within the first preset time T1 in step S103 includes: If the first inclination angle data α1 of the lamp post is greater than the continuous threshold angle α within the first preset time T1, L , it is determined that the top of the first lamp pole is continuously tilted and the street lamp is marked as a first-level warning state; wherein the continuous threshold angle α L <Top threshold angle α T .

[0012] As an improvement, the step of combining the first tilt angle data and the second tilt angle data to determine whether the first lamp pole is tilted in step S107 includes: If the first tilt angle data α1> the continuous threshold angle α L , and the second inclination angle α2> the bottom threshold angle α B , it is determined that the first lamp pole is tilted and the first lamp pole is marked as a state to be repaired; If the first tilt angle data α1> the continuous threshold angle α L , and 0<second inclination angle α2<bottom threshold angle αB , it is determined that the first lamp pole is slightly tilted and the first lamp pole is marked as a second-level warning state.

[0013] As an improvement, when the first lamp pole is in the second-level warning state, the tilt status data of the second lamp pole in the same group as the first lamp pole is collected. If the second lamp poles exceeding the first threshold ratio are all in a tilted state, the state of the first lamp pole is upgraded to the third-level warning state.

[0014] As an improvement, when the first lamp pole is in the third-level warning state, the state of the first lamp pole in the street light group within the threshold range is checked. If all the first lamp poles exceeding the second threshold ratio are in the third-level warning state, the state of all street light groups within the threshold range is upgraded to the state to be repaired.

[0015] As an improvement, the step of determining the inclination of the second lamp pole according to the inclination state data in step S109 includes: If the feedback state of the second sensor is tilted, it is determined that the second lamp pole corresponding to the second sensor is in a tilted state, and the second lamp pole is marked as a state to be repaired.

[0016] As an improvement, in step S101, the first inclination angle data collected by the first sensor at the top of the first lamp pole is collected once at every time interval T0.

[0017] As an improvement, the first sensor is an angle sensor, and the second sensor is a level.

[0018] As an improvement, the group and the first lamp pole and multiple second lamp poles in the group are numbered, and the first sensor and the second sensor correspond one-to-one to the first lamp pole and the second lamp pole to which they belong, so that the number of the first lamp pole or the second lamp pole and the number of the group to which the first lamp pole or the second lamp pole belongs can be obtained through the signal fed back by the first sensor or the second sensor.

[0019] Beneficial effects: Compared with the prior art method of judging the inclination of the lamp pole based on the instantaneous tilt angle value, the present invention determines whether the tilt occurs by judging the continuity of the inclination state of the lamp pole, thereby avoiding the situation where misjudgment is caused by a large shaking of the lamp pole due to external force (for example, wind shaking).

[0020] In the prior art, a precision sensor is installed on each street light pole, and the tilt detection is performed separately based on the tilt data of each street light. This not only makes the cost high, but also greatly increases the data processing volume of the detection system, the power consumption is also large, and the performance requirements of the system equipment are also high. In the present invention, a group method is adopted, and a precision sensor is installed on the street light pole that is most likely to tilt or has the highest probability of tilting, while other street light poles in the same group are installed with sensors with lower sensitivity or precision. On the one hand, it can reduce costs, and on the other hand, it can achieve mutual verification of the tilt state between the two, thereby ensuring the accuracy of tilt detection. In addition, compared with the method of installing precision instruments on each street light, the present invention can achieve group tilt detection (for example, group tilt events caused by strong winds, earthquakes or settlements) at a low cost.

[0021] The present invention divides warning levels, marks maintenance status according to changes in warning status, and then dispatches workers for maintenance accordingly, thereby greatly reducing management and maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Embodiment 1: Figure 2 As shown, the present invention provides a method for detecting the inclination of a street lamp pole, wherein a number of street lamps located on the same road section are divided into a group, each of the street lamp groups includes a first lamp pole and a plurality of second lamp poles; and a first sensor is provided at the top and bottom of the first lamp pole, and a second sensor is provided at the bottom of the second lamp pole; the second sensor can only qualitatively detect the inclination of the lamp pole, while the first sensor can both qualitatively detect the inclination of the lamp pole and quantitatively detect the angle of the inclination of the lamp pole.

[0031] In this embodiment, street lamps are divided into groups for overall management. Generally speaking, street lamps located on the same road section have the same climatic conditions (such as windy and rainy weather) and geological conditions (such as geology prone to settlement), so the street lamp tilt caused by the above two conditions is very likely to become a group phenomenon. Therefore, in principle, the street lamps on the same road section are divided into the same group in the embodiment. Of course, if the area covered by the road section is too large, multiple groups can also be set up on the same road section. On the contrary, when the street lamps on a certain road section are too sparse, they can also be merged into other roads.

[0032] For the convenience of management, the present invention also numbers the groups and the street lamps in the groups. Each group has a unique number, and the street lamp numbers in the group are also unique, so that the corresponding street lamp can be found by the number.

[0033] Specifically, the group and the first lamp pole and multiple second lamp poles in the group are numbered, and the first sensor and the second sensor correspond one-to-one to the first lamp pole and the second lamp pole to which they belong, so that the number of the first lamp pole or the second lamp pole and the number of the group to which the first lamp pole or the second lamp pole belongs can be obtained through the signal fed back by the first sensor or the second sensor.

[0034] It is foreseeable that each street light pole should also be recorded with location information, type information (first light pole or second light pole) and other information to facilitate management.

[0035] In this embodiment, the street lamps include two types, namely, a first street lamp and a second street lamp. The first street lamp is equipped with a first sensor at both the top and the bottom, while the second street lamp is equipped with a second sensor only at the top.

[0036] The difference between the first sensor and the second sensor is that the second sensor can only qualitatively detect the tilt of the lamp pole, while the first sensor can both qualitatively and quantitatively detect the tilt angle of the lamp pole. In other words, the second sensor can only detect whether the street light pole is currently tilted, and there are only two states: tilted or not tilted. As for the tilt angle and duration, it cannot provide information. The second sensor can not only detect whether the street light pole is currently tilted, but also detect the tilt angle and duration.

[0037] Exemplarily, the first sensor is an angle sensor, and the second sensor is a level.

[0038] In other embodiments, the first sensor is a high-sensitivity street lamp tilt detection sensor; compared with the first sensor, the second sensor is a low-sensitivity street lamp tilt detection sensor. For example, when the tilt angle is small, the high-sensitivity sensor can detect it, while the low-sensitivity sensor cannot detect it; for another example, for the same tilt angle, the tilt angle data monitored by the high-sensitivity sensor is closer to the actual tilt angle, or in other words, the error is smaller, while the tilt angle data monitored by the low-sensitivity sensor has a larger error with the actual tilt angle.

[0039] The purpose of setting up two types of sensors is to consider the installation cost and operating cost, especially for street lamps in some suburban roads. If all of them are high-sensitivity sensors or first sensors, the cost will be very high. For example, angle sensors are expensive, precise and easy to damage, while spirit levels are generally cheaper, stable and durable. Angle sensors collect a large amount of data, while spirit levels provide less data feedback. Although the difference between the two is not obvious in terms of one street lamp, due to the large number of street lamps in the entire area, quantitative changes will lead to qualitative changes.

[0040] In this embodiment, each group has a first lamp pole and several second lamp poles, the purpose of which is to accurately sense the tilt of the lamp pole through the first lamp pole, and to assist in verification through the second lamp pole, so as to continuously monitor the group tilt events in the entire area. Preferably, the street lamps installed in the area where the tilt is most likely to occur or the tilt probability is the highest in the same section are statistically analyzed in advance based on the historical data of the road section (or the historical data of similar sections), and that is the first lamp pole. For example, in a road section, the street lamps located in the wind outlet area are most likely to tilt, because when the wind is strong, the wind force at the wind outlet is the largest, so the street lamps in the area are most likely to tilt under the action of the wind. Of course, in other embodiments, there may be multiple street lamps in the area, so there may also be multiple first lamp poles.

[0041] Of course, the present invention is also mainly used in mass tilting events caused by weather factors or geological factors. As for the human-caused collision and tilting of individual lamp poles (such as traffic accidents), in fact, due to the intervention of other departments (such as traffic control departments), it is easy to obtain the tilt information in the first place.

[0042] Accordingly, the method comprises the steps of: S101 collects first tilt angle data collected by the first sensor at the top of the first lamp pole, and determines whether tilt occurs. If so, execute step S103; otherwise, execute step S105.

[0043] In this embodiment, in order to reduce data throughput, data is not collected continuously. Generally speaking, the first tilt angle data collected by the first sensor at the top of the first lamp pole is collected once every interval T0. The length of the interval T0 is adjusted according to actual conditions and is not limited in this embodiment.

[0044] It is understandable that the collective tilting of street lamp poles caused by weather and geological conditions does not happen instantly, but generally takes a tilting process. Therefore, setting an appropriate interval time T0 can not only effectively monitor the tilting of street lamps, but also greatly reduce the amount of data and reduce system overhead.

[0045] In this embodiment, whether tilting occurs is determined by collecting first tilt angle data collected by a first sensor at the top of the first lamp pole.

[0046] In fact, since lamp poles are generally several meters or even more than ten meters high, even if the lamp poles are very rigid (in reality, in order to improve the toughness of lamp poles, materials with too strong rigidity are generally not used, otherwise they are prone to breakage), their tops will still shake in windy weather. Therefore, in this embodiment, the lamp pole tilt detected by the first sensor on the top plate of the first lamp pole actually detects whether the top of the lamp pole is shaking, and cannot directly prove that the entire lamp pole has tilted.

[0047] Specifically, the step of determining the tilt using the first tilt angle data in this step includes: Determine whether the first tilt angle data α1 is greater than the preset top threshold angle α T ; If the first tilt angle data α1> the top threshold angle α T , it is determined that the top of the first lamp pole is tilted and the first lamp pole is marked as a continuous monitoring state; the first lamp pole marked as a continuous monitoring state increases the density of collected data. For the first lamp pole marked as being in continuous monitoring status, the interval for collecting data may be reduced from T0 to T0', thereby increasing the intensity of monitoring.

[0048] S103 determines whether the tilting state of the first lamp pole continues within the first preset time T1, and if so, executes step S107; otherwise, continues monitoring.

[0049] The purpose of this step is to detect whether the tilt state of the first lamp pole is continuous or swinging back and forth. If it swings back and forth, it means that the tilt is temporary, and it is very likely that the top swing is caused by strong winds or other reasons. Of course, it is understandable that excessive top swing may also cause permanent tilt of the lamp pole, which requires continuous monitoring.

[0050] When it is monitored that the inclination of a lamp pole at a certain place continues to exceed the first preset time T1, it means that the top of the lamp pole is not swinging, but may be tilted.

[0051] Specifically, the step of determining whether the tilt state of the first lamp pole continues within the first preset time T1 in this step includes: If the first inclination angle data α1 of the lamp post is greater than the continuous threshold angle α within the first preset time T1, L , it is determined that the top of the first lamp pole is continuously tilted and the street lamp is marked as a first-level warning state; the first lamp pole marked as a continuous monitoring state further increases the density of collected data relative to the continuous monitoring state; wherein the continuous threshold angle α L <Top threshold angle α T .

[0052] Set the persistence threshold angle α L <Top threshold angle α T The reason is that in reality the lamp pole is tilted for some reason. After tilting to the maximum angle, it may rebound to a certain extent and will not continue to maintain the maximum tilt angle.

[0053] The first lamp pole marked as the first level pre-tensioning state shortens the data collection interval T0' to T0''.

[0054] S105 determines that the first lamp pole is currently temporarily tilted and continues monitoring.

[0055] In step S101, if the first tilt angle data α1 ≤ the top threshold angle α T , it means that the inclination of the first lamp pole is small, and continuous monitoring is sufficient, and the time interval for collecting data remains at T0.

[0056] S107 obtains the second tilt angle data collected by the first sensor at the bottom of the first lamp pole, and combines the first tilt angle data and the second tilt angle data to determine whether the first lamp pole is tilted. If tilted, execute step S109, otherwise continue monitoring.

[0057] In step S103, it is monitored that the tilt of the first lamp pole continues for the first threshold time T1, which means that it is not swinging back and forth due to reasons such as strong winds, but it is very likely that it has tilted, so further judgment is required.

[0058] Therefore, in this step, the step of combining the first tilt angle data and the second tilt angle data to determine whether the first lamp pole is tilted includes: If the first tilt angle data α1> the continuous threshold angle α L , and the second inclination angle α2> the bottom threshold angle α B , it is determined that the first lamp pole is tilted and the first lamp pole is marked as a state to be repaired.

[0059] That is, when the first tilt angle data α1> the continuous threshold angle α L , and the second inclination angle α2> the bottom threshold angle α B In this case, by mutual confirmation of the top inclination angle and the bottom inclination angle, it can be considered that the first lamp pole has tilted. At this time, the first lamp pole is marked as waiting for maintenance, and inspection personnel need to be dispatched through the operation and maintenance system to conduct on-site inspections and confirmation. If maintenance is required, it will be carried out.

[0060] If the first tilt angle data α1> the continuous threshold angle α L , and 0<second inclination angle α2<bottom threshold angle α B , it is determined that the first lamp pole is slightly tilted and the first lamp pole is marked as a second-level warning state. The first lamp pole marked as a second-level warning state further increases the density of collected data compared to the first warning state. In addition, when the first inclination angle data α1> the continuous threshold angle α L, and 0<second inclination angle α2<bottom threshold angle α B In this case, it means that the first lamp pole has a certain inclination but is still within the tolerance range and needs closer attention. Therefore, the warning status of the first lamp pole is upgraded from level one to level two, and the interval for collecting data is shortened from T0'' to T0'''.

[0061] After the warning status of the first lamp pole is upgraded to level two, it is also necessary to collect the tilt status data of the second lamp poles in the same group as the first lamp pole. If all the second lamp poles exceeding the first threshold ratio are in a tilted state, the status of the first lamp pole will be upgraded to level three warning status.

[0062] That is to say, when the first lamp pole is slightly tilted, the tilt state of the second lamp pole in the same group needs to be verified to understand whether the tilt is an individual situation of the first lamp pole or there is a risk of overall tilt. Therefore, when the number of tilted second lamp poles in the group exceeds the threshold, it is considered that a group tilt has occurred and needs closer attention. At this time, the status of the first lamp pole is upgraded to the third-level warning state.

[0063] After upgrading to the third-level warning state, it means that the group has shown an overall tilt tendency (maybe still within the tolerance range), and it is necessary to verify it horizontally with other groups. That is, when the first light pole is in the third-level warning state, check the status of the first light pole in the street light group within the threshold range. If all the first light poles exceeding the second threshold ratio are in the third-level warning state, the status of all street light groups within the threshold range will be upgraded to the waiting for maintenance state.

[0064] The collective tilting tendency has spread to the entire area. It is very likely that strong winds and other weather conditions have attacked the street lights in the entire area. At this time, even if the overall situation is still within the tolerable range, it is necessary to dispatch inspectors as soon as possible to conduct on-site inspections. Therefore, the status of the street light groups in the entire area has been upgraded to pending maintenance status and are awaiting processing.

[0065] S109: Obtaining the tilt state data collected by the second sensor on the top of the second lamp pole, and determining the tilt condition of the second lamp pole according to the tilt state data.

[0066] If the first lamp pole has been determined to be in a tilted state in step S107, then the tilt fed back by the second sensor on the second lamp pole in the same group is likely to be the real tilt of the second lamp pole. Therefore, when the tilt state data fed back by the second sensor is tilted, it can be determined that the state of the second lamp pole has tilted, and therefore the second lamp pole needs to be marked as pending maintenance and wait for on-site observation by the inspector.

[0067] Embodiment 2: Based on the above detection method, the present invention also provides a maintenance system based on street lamp pole tilt detection, comprising: A group division module is used to divide a number of street lights located on the same road section into a group, each of the street light groups includes a first lamp pole and multiple second lamp poles; and the top and bottom of the first lamp pole are both provided with a first sensor, and the top of the second lamp pole is provided with a second sensor; the second sensor can only qualitatively detect the inclination of the lamp pole, and the first sensor can both qualitatively detect the inclination of the lamp pole and quantitatively determine the angle of the inclination of the lamp pole.

[0068] In this embodiment, street lamps are divided into groups for overall management. Generally speaking, street lamps located on the same road section have the same climatic conditions (such as windy and rainy weather) and geological conditions (such as geology prone to settlement), so the street lamp tilt caused by the above two conditions is very likely to become a group phenomenon. Therefore, in principle, the street lamps on the same road section are divided into the same group in the embodiment. Of course, if the area covered by the road section is too large, multiple groups can also be set up on the same road section. On the contrary, when the street lamps on a certain road section are too sparse, they can also be merged into other roads.

[0069] In this embodiment, the street lamps include two types, namely, a first street lamp and a second street lamp. The first street lamp is equipped with a first sensor at both the top and the bottom, while the second street lamp is equipped with a second sensor only at the top.

[0070] The difference between the first sensor and the second sensor is that the second sensor can only qualitatively detect the tilt of the lamp pole, while the first sensor can both qualitatively and quantitatively detect the tilt angle of the lamp pole. In other words, the second sensor can only detect whether the street light pole is currently tilted, and there are only two states: tilted or not tilted. As for the tilt angle and duration, it cannot provide information. The second sensor can not only detect whether the street light pole is currently tilted, but also the tilt angle and duration.

[0071] Exemplarily, the first sensor is an angle sensor, and the second sensor is a level.

[0072] In other embodiments, the first sensor is a high-sensitivity street lamp tilt detection sensor; compared with the first sensor, the second sensor is a low-sensitivity street lamp tilt detection sensor. For example, when the tilt angle is small, the high-sensitivity sensor can detect it, while the low-sensitivity sensor cannot detect it; for another example, for the same tilt angle, the tilt angle data monitored by the high-sensitivity sensor is closer to the actual tilt angle, or in other words, the error is smaller, while the tilt angle data monitored by the low-sensitivity sensor has a larger error with the actual tilt angle.

[0073] The purpose of setting up two types of sensors is to consider the installation cost and operating cost, especially for street lamps in some suburban roads. If all of them are high-sensitivity sensors or first sensors, the cost will be very high. For example, angle sensors or high-sensitivity sensors are expensive and precise and easy to damage, while level meters or low-sensitivity sensors are generally cheaper. Angle sensors collect a large amount of data, while level meters provide less data feedback. Although the difference between the two is not obvious in a street lamp, due to the large number of street lamps in the entire area, quantitative changes will lead to qualitative changes.

[0074] In this embodiment, each group has a first lamp pole and several second lamp poles, the purpose of which is to accurately sense the tilt of the lamp pole through the first lamp pole, and to assist in verification through the second lamp pole, so as to continuously monitor the group tilt events in the entire area. Preferably, the street lamps installed in the area where the tilt is most likely to occur or the tilt probability is the highest in the same section are statistically analyzed in advance based on the historical data of the road section (or the historical data of similar sections), and that is the first lamp pole. For example, in a road section, the street lamps located in the wind outlet area are most likely to tilt, because when the wind is strong, the wind force at the wind outlet is the largest, so the street lamps in the area are most likely to tilt under the action of the wind. Of course, in other embodiments, there may be multiple street lamps in the area, so there may also be multiple first lamp poles.

[0075] Of course, the present invention is also mainly used in mass tilting events caused by weather factors or geological factors. As for the human-caused collision and tilting of individual lamp poles (such as traffic accidents), in fact, due to the intervention of other departments (such as traffic control departments), it is easy to obtain the tilt information in the first place.

[0076] A numbering module is used to number a group and a first lamp pole and multiple second lamp poles within the group. The first sensor and the second sensor correspond one-to-one to the first lamp pole and the second lamp pole to which they belong, so that the number of the first lamp pole or the second lamp pole and the number of the group to which the first lamp pole or the second lamp pole belongs can be obtained through the signal fed back by the first sensor or the second sensor.

[0077] For the convenience of management, the present invention also numbers the groups and the street lamps in the groups. Each group has a unique number, and the street lamp numbers in the group are also unique, so that the corresponding street lamps can be found by the numbers. It is foreseeable that each street lamp pole should also be recorded with location information, type information (first lamp pole or second lamp pole) and other information to improve management efficiency and facilitate the search of street lamp information.

[0078] The tilt detection module is used to detect the tilt of the first lamp pole and the second lamp pole; see Figure 2 , the step of tilt detection comprises: S101 collects first tilt angle data collected by the first sensor at the top of the first lamp pole, and determines whether tilt occurs. If so, execute step S103; otherwise, execute step S105.

[0079] In this embodiment, in order to reduce data throughput, data is not collected continuously. Generally speaking, the first tilt angle data collected by the first sensor at the top of the first lamp pole is collected once every interval T0. The length of the interval T0 is adjusted according to actual conditions and is not limited in this embodiment.

[0080] It is understandable that the collective tilting of street lamp poles caused by weather and geological conditions does not happen instantly, but generally takes a tilting process. Therefore, setting an appropriate interval time T0 can not only effectively monitor the tilting of street lamps, but also greatly reduce the amount of data and reduce system overhead.

[0081] In this embodiment, whether tilting occurs is determined by collecting first tilt angle data collected by a first sensor at the top of the first lamp pole.

[0082] In fact, since lamp poles are generally several meters or even more than ten meters high, even if the lamp poles are very rigid (in reality, in order to improve the toughness of lamp poles, materials with too strong rigidity are generally not used, otherwise they are prone to breakage), their tops will still shake in windy weather. Therefore, in this embodiment, the lamp pole tilt detected by the first sensor on the top plate of the first lamp pole actually detects whether the top of the lamp pole is shaking, and cannot directly prove that the entire lamp pole has tilted.

[0083] Specifically, the step of determining the tilt using the first tilt angle data in this step includes: Determine whether the first tilt angle data α1 is greater than the preset top threshold angle α T ; If the first tilt angle data α1> the top threshold angle α T , it is determined that the top of the first lamp pole is tilted and the first lamp pole is marked as a continuous monitoring state; the first lamp pole marked as a continuous monitoring state increases the density of collected data. For the first lamp pole marked as being in continuous monitoring status, the interval for collecting data may be reduced from T0 to T0', thereby increasing the intensity of monitoring.

[0084] S103 determines whether the tilting state of the first lamp pole continues within the first preset time T1, and if so, executes step S107; otherwise, continues monitoring.

[0085] The purpose of this step is to detect whether the tilt state of the first lamp pole is continuous or swinging back and forth. If it swings back and forth, it means that the tilt is temporary, and it is very likely that the top swing is caused by strong winds or other reasons. Of course, it is understandable that excessive top swing may also cause permanent tilt of the lamp pole, which requires continuous monitoring.

[0086] When it is monitored that the inclination of a lamp pole at a certain place continues to exceed the first preset time T1, it means that the top of the lamp pole is not swinging, but may be tilted.

[0087] Specifically, the step of determining whether the tilt state of the first lamp pole continues within the first preset time T1 in this step includes: If the first inclination angle data α1 of the lamp post is greater than the continuous threshold angle α within the first preset time T1, L , it is determined that the top of the first lamp pole is continuously tilted and the street lamp is marked as a first-level warning state; the first lamp pole marked as a continuous monitoring state further increases the density of collected data relative to the continuous monitoring state; wherein the continuous threshold angle α L <Top threshold angle α T .

[0088] Set the persistence threshold angle α L <Top threshold angle α T The reason is that in reality the lamp pole is tilted for some reason. After tilting to the maximum angle, it may rebound to a certain extent and will not continue to maintain the maximum tilt angle.

[0089] The first lamp pole marked as the first level pre-tensioning state shortens the data collection interval T0' to T0''.

[0090] S105 determines that the first lamp pole is currently temporarily tilted and continues monitoring.

[0091] In step S101, if the first tilt angle data α1 ≤ the top threshold angle α T , it means that the inclination of the first lamp pole is small, and continuous monitoring is sufficient, and the time interval for collecting data remains at T0.

[0092] S107 obtains the second tilt angle data collected by the first sensor at the bottom of the first lamp pole, and combines the first tilt angle data and the second tilt angle data to determine whether the first lamp pole is tilted. If tilted, execute step S109, otherwise continue monitoring.

[0093] In step S103, it is monitored that the tilt of the first lamp pole continues for the first threshold time T1, which means that it is not swinging back and forth due to reasons such as strong winds, but it is very likely that it has tilted, so further judgment is required.

[0094] Therefore, in this step, the step of combining the first tilt angle data and the second tilt angle data to determine whether the first lamp pole is tilted includes: If the first tilt angle data α1> the continuous threshold angle α L , and the second inclination angle α2> the bottom threshold angle α B , it is determined that the first lamp pole is tilted and the first lamp pole is marked as a state to be repaired.

[0095] That is, when the first tilt angle data α1> the continuous threshold angle α L , and the second inclination angle α2> the bottom threshold angle α B In this case, by mutual confirmation of the top inclination angle and the bottom inclination angle, it can be considered that the first lamp pole has tilted. At this time, the first lamp pole is marked as waiting for maintenance, and inspection personnel need to be dispatched through the operation and maintenance system to conduct on-site inspections and confirmation. If maintenance is required, it will be carried out.

[0096] If the first tilt angle data α1> the continuous threshold angle α L , and 0<second inclination angle α2<bottom threshold angle α B , it is determined that the first lamp pole is slightly tilted and the first lamp pole is marked as a second-level warning state. The first lamp pole marked as a second-level warning state further increases the density of collected data compared to the first warning state. In addition, when the first inclination angle data α1> the continuous threshold angle α L , and 0<second inclination angle α2<bottom threshold angle α B In this case, it means that the first lamp pole has a certain inclination but is still within the tolerance range and needs closer attention. Therefore, the warning status of the first lamp pole is upgraded from level one to level two, and the interval for collecting data is shortened from T0'' to T0'''.

[0097] After the warning status of the first lamp pole is upgraded to level two, it is also necessary to collect the tilt status data of the second lamp poles in the same group as the first lamp pole. If all the second lamp poles exceeding the first threshold ratio are in a tilted state, the status of the first lamp pole will be upgraded to level three warning status.

[0098] That is to say, when the first lamp pole is slightly tilted, the tilt state of the second lamp pole in the same group needs to be verified to understand whether the tilt is an individual situation of the first lamp pole or there is a risk of overall tilt. Therefore, when the number of tilted second lamp poles in the group exceeds the threshold, it is considered that a group tilt has occurred and needs closer attention. At this time, the status of the first lamp pole is upgraded to the third-level warning state.

[0099] After upgrading to the third-level warning state, it means that the group has shown an overall tilt tendency (maybe still within the tolerance range), and it is necessary to verify it horizontally with other groups. That is, when the first light pole is in the third-level warning state, check the status of the first light pole in the street light group within the threshold range. If all the first light poles exceeding the second threshold ratio are in the third-level warning state, the status of all street light groups within the threshold range will be upgraded to the waiting for maintenance state.

[0100] The collective tilting tendency has spread to the entire area. It is very likely that strong winds and other weather conditions have attacked the street lights in the entire area. At this time, even if the overall situation is still within the tolerable range, it is necessary to dispatch inspectors as soon as possible to conduct on-site inspections. Therefore, the status of the street light groups in the entire area has been upgraded to pending maintenance status and are awaiting processing.

[0101] S109: Obtaining the tilt state data collected by the second sensor on the top of the second lamp pole, and determining the tilt condition of the second lamp pole according to the tilt state data.

[0102] If the first lamp pole has been determined to be in a tilted state in step S107, then the tilt fed back by the second sensor on the second lamp pole in the same group is likely to be the real tilt of the second lamp pole. Therefore, when the tilt state data fed back by the second sensor is tilted, it can be determined that the state of the second lamp pole has tilted, and therefore the second lamp pole needs to be marked as pending maintenance and wait for on-site observation by the inspector.

[0103] Based on the above steps, the tilt detection module specifically includes: a first judgment unit, which is used to collect the first tilt angle data collected by the first sensor at the top of the first lamp pole, and judge whether the first lamp pole is tilted according to the first tilt data; a second judgment unit, which is used to judge whether the tilt state of the lamp pole continues within a first preset time T1 when the first judgment unit judges that the first lamp pole is tilted; a third judgment unit, which is used to judge that the first lamp pole is currently temporarily tilted and continuously monitor when the first judgment unit judges that the first lamp pole is not tilted; a fourth judgment unit, which is used to obtain the second tilt angle data collected by the first sensor at the bottom of the first lamp pole when the second judgment unit judges that the tilt state of the first lamp pole is not continued within T1, and judge whether the first lamp pole is tilted in combination with the first tilt angle data and the second tilt angle data; a fifth judgment unit, when the fourth judgment unit judges that the first lamp pole is tilted, obtains the tilt state data collected by the second sensor at the top of the second lamp pole, and judges the tilt of the second lamp pole according to the tilt state data.

[0104] The system of this embodiment further includes an inspection configuration module, which is used to configure inspection personnel to perform inspections according to the results of the inclination detection of the first lamp pole and the second lamp pole.

[0105] The method for configuring patrol personnel by the patrol configuration module in the present invention includes: S111: When a first light pole, a second light pole or a group is marked as being in maintenance status, the inspection configuration module obtains the geographic location of the first light pole, the second light pole or the group according to the number of the first light pole, the second light pole or the group.

[0106] The first light pole, the second light pole and the group they belong to have been pre-numbered, and the sensor is bound to the light pole, so once the sensor senses that the light pole is tilted, it can be determined which light pole or group has a problem. And because the location information of the light poles is pre-recorded, the geographical location of the light pole or group can be quickly obtained.

[0107] S113 searches for inspectors within a threshold radius with the geographical location as the center of the circle, and uses the searched inspectors as candidate inspectors.

[0108] In order to allow the inspectors to check and verify the tilted lamp pole or group location as soon as possible, in this embodiment, the tilted lamp pole or group is used as the center of the circle to search for nearby inspectors, and all inspectors within the range are used as candidates, and the most suitable one is recommended from the candidates for inspection.

[0109] S115 obtains a task list of candidate inspectors and the distance between the location of the last task in the task list and the geographical location, and calculates a recommendation index based on the task list and the distance.

[0110] It is understandable that the closer the distance between the inspector and the location to be inspected is, the better. However, distance is not the only consideration. Inspectors have tasks to complete, and generally, they will complete the previous task before moving on to the next task. Therefore, it is possible that the nearest inspector has many tasks to complete and cannot reach the scene the fastest.

[0111] Therefore, in this embodiment, the recommendation index is calculated using the candidate inspection personnel task list and the distance between the location of the last task in the task list and the geographical location as recommended factors.

[0112] Specifically, the steps of calculating the recommendation index of the task list and distance include: Calculate the waiting time based on the duration of each task in the task list; Using the formula S=(T*a+D*b) -1Calculate the recommendation index; where S is the recommendation index, T is the waiting time, D is the distance, a is the time coefficient, and b is the distance coefficient; a<b.

[0113] It is understandable that if a patrol officer has two tasks in his task list, one of which takes 1 hour and the other takes half an hour, then the waiting time for the patrol officer is 1.5 hours. If the last task of the patrol officer is 5 kilometers away from the location where the light pole is tilted, then the recommended index is calculated based on 1.5 hours as the waiting time and 5 kilometers as the distance.

[0114] Since the entire system dispatches workers nearby, and inspectors have their own inspection areas, the weight of distance is actually smaller than the weight of waiting time. For example, even if an inspector is 20 kilometers away from the scene of the incident, it only takes 20 minutes according to his speed of 60 km / h in the urban area. Generally speaking, an ordinary inspection task takes more than 30 minutes, so the weight of waiting time is set higher in this embodiment. Of course, the specific time coefficient and distance coefficient are determined according to the actual situation, and are not limited in the present invention.

[0115] S117 assigns the inspection task of the first lamp pole, the second lamp pole or the group to the inspector with the highest recommendation index.

[0116] It is understandable that the higher the recommendation index of a patrol officer, the more free he is and the closer he is to the scene of the incident, and the more suitable he is for patrolling the scene of the incident.

[0117] In addition, the present invention plans a route for the inspector with the highest recommendation index to the geographical location; and adds the inspection task of the first lamp pole marked as a third-level warning state on the route to the task list of the inspector.

[0118] The first lamp pole in the third-level warning state is in a slightly tilted state and there is a risk of group tilting. Therefore, when inspectors pass by, they can observe with the naked eye to determine whether there is a tilt that has not been detected.

[0119] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0120] Through the description of the above implementation methods, those skilled in the art can clearly understand that the above-mentioned embodiment methods can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present invention, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for a computer terminal (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods described in each embodiment of the present invention.

[0121] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation modes, which are merely illustrative rather than restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are within the protection of the present invention.
