Description

Technical Field

[0001] The present invention belongs to the technical field of smart lamp poles, and in particular to a smart lamp pole and an intelligent control method. Background Art

[0002] Smart light poles are a new type of urban infrastructure that integrates a variety of smart devices and services. It not only has traditional lighting functions, but also integrates multiple technologies such as video surveillance, traffic management, environmental monitoring, and communication services to provide support for building smart cities.

[0003] During the operation of the smart light pole, due to the complexity of its internal components and wiring harness, the heat generated by the smart light pole during normal operation is higher than that of an ordinary light pole. In view of the risk of short circuit or spontaneous combustion of ordinary light poles when they are in long-term operation and lack maintenance for a long time, the risk of short circuit or spontaneous combustion of smart light poles will be higher. In order to ensure that the internal temperature of the smart light pole is within the threshold during normal operation, a temperature sensor is added to monitor the temperature inside the light pole module and record the temperature changes inside the light pole. When the temperature exceeds the set temperature threshold, an alarm signal is output to alarm, and the terminal performs inspections and necessary cooling measures, that is, shutting down the smart light pole and restarting it when the temperature is lower than the set threshold.

[0004] In the prior art, since the various electrical devices will generate more heat than ordinary lamp poles when the smart lamp poles are in operation due to long-term operation, and since the various electrical devices are connected to the lamp poles, some heat will accumulate inside the lamp poles. At the same time, the wires used to connect the various electrical devices will also generate heat when they are powered on for a long time, resulting in the heat accumulated inside the lamp poles being difficult to quickly discharge from the lamp poles, causing the various electronic devices inside the lamp poles to be damaged by being in a high-temperature environment for a long time. Therefore, necessary heat dissipation measures can ensure the stable operation of the smart lamp poles when they are in operation, and avoid easy failures or damage. However, the prior art can only decide to shut down the smart lamp poles based on the monitored temperature, without considering whether shutting down the smart lamp poles will affect the lives of residents. Although it can prevent the smart lamp poles from being damaged by being in a high-temperature state for a long time, it also hinders the lives of residents.

[0051] Preferably, when the heat dissipation module is in operation, when the wind speed Vjr of the air inlet through hole on the lamp pole module is 0, and the wind speed Vcr of the air outlet through hole is 0, it indicates that the heat dissipation module is not operating normally.

[0054] The present invention will be further described below in conjunction with the accompanying drawings.

[0057] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0058] like Figure 1 As shown, a smart lamp pole described in an embodiment of the present invention includes a lamp pole module, wherein the lamp pole module is composed of a first lamp pole, a second lamp pole and a third lamp pole fixedly connected in sequence; electrical equipment includes an LED lamp group, which is arranged on the lamp pole module; the electrical equipment also includes a solar panel, which is fixedly connected to the top of the third lamp pole and is used to convert solar energy into electrical energy; the LED lamp group, which is used for lighting, is fixedly connected to one side of the top of the third lamp pole; a camera, which is fixedly connected to the other side of the top of the third lamp pole; an advertising box, which is fixedly connected to the second lamp pole; a power storage box, which is arranged at the bottom of the first lamp pole, and the LED lamp group, solar panel, camera and advertising box are electrically connected to the power storage box; the side walls of the chambers in the first lamp pole, the second lamp pole and the third lamp pole are each provided with two through holes, and the two through holes are spaced apart from each other; a heat dissipation module is also included, which is used to dissipate heat from the lamp pole module; a control system is also included;

[0059] The control system includes: a temperature acquisition module, which is used to monitor and collect the temperature of the lamp pole module, including the real-time temperature and the temperature during heat dissipation; a judgment module, which controls the operation of the heat dissipation module according to the relationship between the real-time temperature and the threshold; and an analysis module, which controls the LED light group according to the temperature change trend during heat dissipation.

[0060] During the operation of the smart lamp pole, due to the complexity of its internal components and wiring harness, the heat generated by the smart lamp pole during normal operation is higher than that of an ordinary lamp pole. In view of the risk of short circuit or spontaneous combustion of ordinary lamp poles when they are in long-term operation and lack maintenance for a long time, the risk of short circuit or spontaneous combustion of smart lamp poles will be higher. Moreover, since all electrical equipment is connected to the lamp pole, some heat will accumulate inside the lamp pole. For example, the advertising box and the control system will generate heat during operation, and the heat is mainly concentrated in the lamp pole module. At the same time, the wires used to connect the electrical equipment will also generate heat when they are powered on for a long time, resulting in the heat accumulated inside the lamp pole being difficult to be quickly discharged from the lamp pole, causing the electronic components inside the lamp pole to be damaged in a high-temperature environment for a long time. As an embodiment of the present invention, by setting a temperature acquisition module, the temperature inside the lamp pole module can be acquired, and the judgment module is used to judge the relationship between the acquired real-time temperature and the threshold value. When the real-time temperature is greater than the temperature threshold, the heat dissipation is controlled. When the module is started, the inside of the lamp pole module is cooled and cooled to avoid continuous high temperature inside the lamp pole module and the occurrence of faults; secondly, when the inside of the lamp pole module is hot, that is, the real-time temperature is greater than the temperature threshold, it is necessary to analyze whether the heat dissipation module plays a role in cooling the lamp pole module. If the heat dissipation module does not play a cooling role, resulting in the lamp pole module being in high temperature for a long time, it is easy to cause the lamp pole module to fail; therefore, the heat dissipation temperature of the lamp pole module is continuously monitored during the operation of the heat dissipation module by analyzing the module. When the temperature change trend during heat dissipation is an upward trend, it means that the heat dissipation module is unable to cool the lamp pole module. At this time, it is necessary to reduce the brightness of the LED light group or turn off the LED light group for heat dissipation, otherwise it may cause continuous high temperature inside the lamp pole module and cause the occurrence of faults. When the temperature change trend during heat dissipation is a downward trend, it means that the heat dissipation module has effectively cooled the lamp pole module. At this time, there is no need to reduce the brightness of the LED light group or turn off the LED light group.

[0061] In addition, in the prior art, the lamp pole module is usually an integrated structure, and in order to facilitate heat dissipation, an air inlet at the bottom of the lamp pole and an air outlet at the top are usually provided. When heat is dissipated, the heat inside the lamp pole module can be discharged by the air inlet and the air outlet. However, in the prior art, after the cold air flow enters the lamp pole module, as the air flow is guided, the heat carried increases, and it is difficult to effectively dissipate the heat of the equipment near the air outlet end. Therefore, in this embodiment, the lamp pole module is provided with a combination of a first lamp pole, a second lamp pole and a third lamp pole. In order to prevent the air flow flowing through the first lamp pole in the lamp pole module from entering the second lamp pole and the third lamp pole after carrying the heat, causing the temperature inside the lamp pole module to be unable to drop quickly, or it is difficult to cool the upper end of the lamp pole module, independent air inlet holes and air outlet holes are provided inside the first lamp pole, the second lamp pole and the third lamp pole. After the heat dissipation module is operated, the first lamp pole, the second lamp pole and the third lamp pole can be cooled respectively, thereby avoiding the problem that some areas inside the lamp pole module are difficult to cool.

[0062] In addition, in order to prevent water from entering the smart light pole, an L-shaped rain shield is installed from the eaves of the smart light pole equipment compartment to the back panel of the electrical panel. The power supply and network lines of all smart light pole mounted equipment are strictly connected from the bottom of the electrical panel. The base of the smart light pole has holes for drainage of water that may enter on rainy days to prevent water accumulation in the pole.

[0063] In one embodiment, the temperature acquisition module includes a plurality of temperature sensors, which are respectively arranged in the first lamp pole, the second lamp pole and the third lamp pole.

[0064] Since in this embodiment, the lamp pole module is composed of a first lamp pole, a second lamp pole and a third lamp pole, independent temperature sensors are arranged in the first lamp pole, the second lamp pole and the third lamp pole, which is conducive to accurately obtaining the temperature data of each chamber in the lamp pole module; wherein the chamber represents the internal space of the first lamp pole, the second lamp pole and the third lamp pole, which is mainly used to store wiring harnesses.

[0065] In one embodiment, the heat dissipation module includes a rotating shaft rotatably connected to the bottom of the inner cavity of the first lamp pole, and the top of the rotating shaft is rotatably connected to the top of the inner cavity of the third lamp pole; the first lamp pole, the second lamp pole, and the third lamp pole are separated by partitions; the rotating shaft passes through multiple partitions in sequence; multiple fan blades are fixed to the rotating shaft, and the fan blades are respectively arranged inside the first lamp pole, the second lamp pole, and the third lamp pole.

[0066] When the smart lamp pole is in operation, too many electrical devices may cause continuous high heat inside the lamp pole module, thereby causing a malfunction. Therefore, as an embodiment of the present invention, when the real-time temperature is greater than the temperature threshold, the control system is used to control the start of the heat dissipation module, that is, the start of the motor connected to the shaft is controlled by an electrical signal. When the motor is started, the shaft can be driven to rotate, thereby driving the fan blades located in the multiple chambers to rotate. After the fan blades rotate, independent airflow guides are formed inside the first lamp pole, the second lamp pole and the third lamp pole, so that external cold air can be sucked into each chamber. After the airflow is discharged from the chamber, the heat in each chamber can be taken out, thereby cooling the first lamp pole, the second lamp pole and the third lamp pole, and avoiding continuous high heat inside the lamp pole module, which causes a malfunction of the smart lamp pole.

[0067] Among them, the rotating shaft is coaxially arranged with the lamp pole module and fixed by a partition. A coupling is arranged on the partition, and the rotating shaft is designed in sections. The two rotating shafts are fixed by the coupling on the partition. In addition, since the power storage box is arranged in the first lamp pole, the wiring harness electrically connected to the power storage box passes through multiple partitions and is connected to the electrical equipment, and the connection part between the wiring harness and the partition is sealed with sealing material to prevent the airflow from generating turbulence in multiple chambers.

[0068] In one embodiment, it further includes a plurality of air filter modules, which are respectively arranged adjacent to the through holes; the air filter modules include a filter screen and an anemometer; the filter screen is attached to the inner side of the through hole, and the anemometer is arranged opposite to the filter screen.

[0069] Since the fan blades are used to generate directional airflow for physical heat dissipation, the directional airflow may bring dust and external impurities into the chamber when entering the chamber, thereby causing a large amount of dust and impurities to accumulate inside the lamp pole module, which may also cause short circuit or failure of electrical equipment to a certain extent, thereby affecting the use of the smart lamp pole. For this reason, as an embodiment of the present invention, an air filter module is arranged on the inner side of the through hole, that is, a filter is attached to the inner side of the through hole, and the filter is used to block dust and impurities to prevent a large amount of dust and impurities from entering the chamber and causing failure or short circuit of electrical equipment. In addition, a wind speed meter is also arranged to monitor the wind speed at the through hole position. If the wind speed at the through hole position is zero during the operation stage of the heat dissipation module, it means that the filter is blocked and no directional airflow can be generated. Therefore, the effect of cooling the lamp pole module cannot be achieved.

[0070] An intelligent control method for a smart lamp pole comprises the following steps:

[0071] Get the real-time temperature of the light pole module;

[0072] When the real-time temperature is greater than the temperature threshold, a signal is output to the control system;

[0073] The control system receives the signal, starts the heat dissipation module, records the temperature of the lamp pole module during heat dissipation, and obtains the temperature change curve during heat dissipation;

[0074] When the temperature shows an upward trend during heat dissipation, the lighting demand value of the smart lamp pole is obtained and an alarm is issued to the terminal; when the lighting demand value of the smart lamp pole is greater than or equal to the lighting demand threshold, the lighting brightness of the LED lamp group is reduced;

[0075] When the lighting demand value of the smart lamp pole is less than the lighting demand threshold, the LED light group is turned off;

[0076] When heat is dissipated, the temperature tends to decrease, maintaining the operation of the heat dissipation module.

[0077] During the operation of the smart lamp pole, the temperature sensor monitors the real-time temperature of multiple chambers inside the lamp pole module in real time. If the real-time temperature in a chamber exceeds the threshold, the control system controls the heat dissipation module to operate and achieve cooling. During the operation stage of the heat dissipation module, the temperature sensor is also needed to monitor the heat dissipation temperature of multiple chambers. The heat dissipation temperature monitored after a period of time, and the change trend of the heat dissipation temperature, reflect whether the heat dissipation module is effective in cooling the chamber. If the heat dissipation temperature is on an upward trend, it is necessary to control the LED light group to turn off or reduce the lighting brightness, otherwise the smart lamp pole will continue to be hot, causing malfunction or damage. If the heat dissipation temperature is on a downward trend, it means that the heat dissipation module has effectively cooled the chamber. At this time, the heat dissipation temperature is monitored by the temperature sensor until the heat dissipation temperature is lower than the threshold, and the heat dissipation module is turned off by the control system. The temperature threshold is obtained from experience, and different temperature thresholds are set according to different ambient temperatures. The lighting demand threshold is also obtained from experience and is determined according to the flow of people in the smart lamp pole in each historical time period.

[0078] Among them, during the operation of the smart lamp pole, except for the LED lamp group, the heat generated by other electrical equipment is limited. When the LED lamp group is in operation, part of the electrical energy will be converted into light energy, and the other part will be released in the form of heat energy. Since the LED lamp group is connected to the lamp pole module, the released heat energy will accumulate in the lamp pole module, thereby causing abnormal temperature of the smart lamp pole. Therefore, when the heat dissipation module cannot effectively cool down, adjusting the brightness of the LED lamp group or turning off the LED lamp group can achieve control of the temperature of the smart lamp pole or achieve preliminary cooling. As for turning off the LED lamp group or reducing the lighting brightness of the LED lamp group, it needs to be determined according to the time period and traffic flow of the smart lamp pole, that is, the lighting demand value. If the lighting demand value of the smart lamp pole is large, that is, it exceeds the threshold, the lighting brightness of the LED lamp group can only be reduced to ensure basic lighting needs. If the lighting demand value is small and does not exceed the threshold, the LED lamp group can be turned off to achieve rapid cooling of the smart lamp pole.

[0079] In addition, when the brightness of the LED light group on a smart lamp pole decreases, the terminal determines whether the temperature of the smart lamp pole at the adjacent position exceeds the temperature threshold. If it does not exceed the temperature threshold, in order to ensure the lighting brightness requirements, the terminal sends a signal to the adjacent smart lamp pole, and then the control system on the adjacent smart lamp pole controls the brightness of the LED light group to increase, thereby compensating for the problem of reduced lighting brightness in the local area caused by the reduced brightness of the LED light group on the smart lamp pole.

[0080] In one embodiment, the method for obtaining the lighting demand value of the smart lamp pole is:

[0081] Divide the historical operation time of the LED light group into segments and count the number of people passing through the smart light pole in each time period;

[0082] Calculate the lighting demand value of the smart lamp pole based on the time period and traffic flow, recorded as Px;

[0083]

[0084] Where x represents the time period, x=1, 2, 3...k; Qx represents the flow of people passing through the smart light pole during the time period; Indicates the total flow of people during the operation period of the LED light group;

[0085] When the smart lamp pole cools down and the temperature of the smart lamp pole lighting demand value is less than the lighting demand threshold, the LED light group is turned off.

[0086] When the smart light pole is in operation, the flow of people passing through the smart light pole is different in each time period. Therefore, when analyzing the lighting demand value of the smart light pole, it is necessary to combine the historical operation time of the LED light group and the flow of people for calculation;

[0087] In one embodiment of the present invention, the historical operation time of the LED lamp group for multiple days is segmented, and then the flow of people passing through the smart lamp pole in each time period is counted, and the estimated flow of people in each time period is obtained by solving the average value, and then the lighting demand value of each time period is converted according to the estimated flow of people in each time period;

[0088] When the temperature inside the lamp pole module is continuously high and the heat dissipation temperature of the heat dissipation module keeps rising during operation, the lighting demand value of the time period is compared with the lighting demand threshold. If the lighting demand value of this time period is less than the lighting demand threshold, the LED light group can be turned off. If the lighting demand value of this time period is greater than or equal to the lighting demand threshold, the lighting brightness of the LED light group can only be reduced to ensure the basic lighting effect.

[0089] In addition, when a vehicle passes by, a certain lighting effect can also be produced. In the same time period, if a vehicle passes by, the lighting demand value of the time period will decrease, otherwise it will remain unchanged; Based on the above;

[0090] According to the formula:

[0091]

[0092] Among them, Lx represents the traffic volume passing through the smart light pole during this time period;

[0093] Based on the above, when the traffic volume passing through the smart lamp pole is greater in the same time period, the calculated new lighting demand value Px* decreases more relative to Px, and vice versa, the closer Px* is to Px; when Lx=0, it means that no vehicle passes through the smart lamp pole in this time period, then Px*=Px; that is, when traffic volume is identified, the new lighting demand value Px* can be used to replace the above lighting demand value Px for judgment, thereby controlling the operation of the LED light group.

[0094] In addition, the vehicle flow mentioned above refers to the number of vehicles with more than two wheels and equipped with lights passing the smart light pole per unit time; the pedestrian flow refers to the number of pedestrians and vehicles with less than two wheels and without lights, such as bicycles, passing the smart light pole per unit time;

[0095] In one embodiment, the method for obtaining the temperature change curve during heat dissipation is:

[0096] Record the temperature of the lamp pole module during heat dissipation in equal time periods, denoted as Ti, i = 1, 2, 3...n;

[0097] According to the time period and Ti, a line graph of the temperature and time period during heat dissipation is established;

[0098] As the time period changes, if the line graph shows an upward trend, an alarm signal is output to the terminal and the smart light pole is maintained.

[0099] During the operation of the heat dissipation module, the data monitored by the temperature sensor is used as the heat dissipation temperature. Multiple heat dissipation temperatures are recorded and counted at fixed time intervals. Based on the recorded heat dissipation temperatures at multiple time points, a trend line graph of the heat dissipation temperature changes with time points is drawn with time point distribution. If the line graph shows that the heat dissipation temperature is on an upward trend, an alarm signal is output to the terminal, and the terminal maintenance personnel perform on-site maintenance on the smart lamp pole that generates the alarm signal.

[0100] In one embodiment, the method for maintaining the smart lamp pole is:

[0101] Number all smart light poles in the area, record them as Dy, y=1, 2, 3...s, and record the actual coordinates of each smart light pole;

[0102] When the alarm signal is output to the terminal, the terminal displays the smart lamp pole Dy that outputs the alarm signal;

[0103] Find the specific coordinates of the smart light pole Dy on the terminal;

[0104] Maintain the smart light pole that sends out the alarm signal according to the coordinate value;

[0105] Screen the light pole modules for clogged air filter modules and clean them.

[0106] Since multiple smart light poles are set up in the area, when a smart light pole generates an alarm signal, in order to quickly find the position of the smart light pole that generates the alarm signal, all the smart light poles in the management area are numbered in advance, and the actual coordinates of all the smart light poles are recorded. When a smart light pole generates an alarm signal, the terminal can display the number and specific coordinate values ​​of the smart light pole accordingly. The terminal maintenance personnel can quickly find the corresponding smart light pole according to the number and specific coordinate values, so that they can quickly maintain the smart light pole to avoid the smart light pole being in a continuous high temperature state for too long due to screening faulty smart light poles for too long, thereby causing failure or damage; among them, the alarm signal issued by the smart light pole indicates that the temperature is on an upward trend during heat dissipation, that is, the heat dissipation module cannot effectively dissipate heat; and the heat dissipation module cannot effectively dissipate heat including two situations, one is that the heat generated by the smart light pole per unit time is higher than the heat discharged by the heat dissipation module, and the other is that the heat dissipation module is not working.

[0107] In one embodiment, the method for screening the air filter module for blockage on the lamp pole module is:

[0108] The terminal sends a signal to the control system to control the operation of the heat dissipation module;

[0109] Mark the air inlet and outlet holes on the light pole module and monitor the wind speed;

[0110] The wind speed Vjr at the air inlet hole and the wind speed Vcr at the air outlet hole are obtained respectively; wherein r represents a hole in any chamber on the smart lamp pole; r=1, 2, 3;

[0111] Determine the magnitude of wind speed Vjr and wind speed Vcr;

[0112] If the wind speed Vjr = 0 or Vcr = 0, it means that the filter at the air inlet hole is completely blocked or the filter at the air outlet hole is completely blocked;

[0113] When Vjr<Vcr, and Vjr≠0, it means that the filters at the air inlet and outlet holes are normal;

[0114] When Vjr≥Vcr and Vcr≠0, it means that the filter at the air outlet is partially blocked.

[0115] After the smart light pole that sends out an alarm signal is screened, if there are multiple air filter modules on the smart light pole, it is not possible to directly find the location of the blocked air filter module on the smart light pole;

[0116] Therefore, after screening the smart lamp pole that sends out an alarm signal, it is necessary to conduct a secondary screening to find out where the blockage occurs. The secondary screening also takes a period of time, which causes the smart lamp pole to be in a high temperature state for too long, which may also cause damage or failure of the smart lamp pole. In order to accurately and quickly find the blockage location, in this embodiment, by obtaining the wind speed of different through holes, that is, the wind speed Vjr of the air inlet through hole and the wind speed Vcr of the air outlet through hole in the same chamber, the location of the blockage on the smart lamp pole can be determined, and the blocked filter can be maintained accordingly according to the determination result;

[0117] For example, the through holes on the first lamp pole, the second lamp pole and the third lamp pole are respectively recorded as: (Vj1, Vc1), (Vj2, Vc2), (Vj3, Vc3);

[0118] When Vj1, Vj2 or Vj3 = 0, it means that the air inlet through hole of the corresponding chamber is blocked; when Vc1, Vc2 or Vc3 = 0, it means that the air outlet through hole of the corresponding chamber is blocked;

[0119] If Vj1≥Vc1, and Vc1≠0, it means that the air outlet filter of the chamber is blocked; similarly, when Vj2≥Vc2, and Vc2≠0 or Vj3≥Vc3, and Vc3≠0, it means that the air outlet filter of the chamber is blocked;

[0120] In one embodiment, when the heat dissipation module is in operation, when the wind speed Vjr of the air inlet through hole on the lamp pole module is 0, and the wind speed Vcr of the air outlet through hole is 0, it indicates that the heat dissipation module is not operating normally.

[0121] As mentioned above, when Vj1-=0, Vc1=0, Vj2=0, Vc2=0, Vj3=0, Vc3=0, it means that the heat dissipation module is not working properly or all the through holes are blocked. At this time, maintenance personnel are required to check the smart light pole to find the specific cause of the alarm to prevent the smart light pole from being in a high temperature state for a long time and malfunctioning or being damaged.

[0122] Working principle: By setting up the temperature acquisition module, the temperature inside the lamp pole module can be collected, and the judgment module is used to judge the relationship between the collected real-time temperature and the threshold. When the real-time temperature is greater than the temperature threshold, the heat dissipation module is controlled to start, and the heat is dissipated and cooled inside the lamp pole module to avoid the continuous high temperature inside the lamp pole module and cause malfunctions; secondly, when the lamp pole module is hot, that is, the real-time temperature is greater than the temperature threshold, it is necessary to analyze whether the heat dissipation module plays a role in cooling the lamp pole module. If the heat dissipation module does not play a cooling role, causing the lamp pole module to be in high temperature for a long time, it is easy to cause the lamp pole module to be A failure occurs; therefore, the analysis module continuously monitors the heat dissipation temperature of the lamp pole module during the operation of the heat dissipation module. When the temperature change trend during heat dissipation is an upward trend, it means that the heat dissipation module is unable to cool the lamp pole module. At this time, it is necessary to reduce the brightness of the LED light group or turn off the LED light group for heat dissipation. Otherwise, the lamp pole module may continue to have high temperature inside and cause a failure. When the temperature change trend during heat dissipation is a downward trend, it means that the heat dissipation module has effectively cooled the lamp pole module. At this time, there is no need to reduce the brightness of the LED light group or turn off the LED light group.
