Description

Technical Field

[0001] The present invention belongs to the technical field of municipal street lamp facilities, and in particular, relates to a smart lamp pole control system and method. Background Art

[0002] With the continuous development of municipal street lighting facilities, the Internet of Things technology and the iteration of the information industry, traditional municipal street lights can achieve remote adjustment of street light illumination by adding dimming controllers. On the street light side, sensors and remote communication controllers are installed, and data is transmitted back and displayed and remotely controlled through the remote platform, which can transform traditional street lights into new smart light poles. The pole body can not only expand functions such as urban public wifi, information release, and one-button alarm, but also derive new applications of wind and solar complementarity and new energy vehicle charging equipment in combination with the continuous growth of today's new energy industry.

[0003] Smart light pole control systems are generally composed of lighting fixtures, controllers, pole bodies, sensor devices, remote management platforms and other component modules. They realize networking and information management of remote devices through information collection and command issuance.

[0004] The existing smart light pole related control usually uses LED modules with dimmable drivers, supporting 0-10v or pulse width dimming. The street light controller can send instructions based on the remote host computer, or control the street light switch by simple local configuration, and output 0-10v or pulse width dimming signals to control the street light illumination to realize the function of light networking.

[0005] The commonly used communication forms in the process of remote control of the controller are CAT1, Lora, and carrier communication. CAT1 and Lora are wireless communication forms, and power carrier is a wired communication form. Due to the simple deployment structure, small amount of integrated wiring engineering, fast transmission, and complete technical resources, the application market of wireless communication has been growing in recent years. With the improvement of the Internet of Things card business of communication operators and the adjustment of tariffs, the cost of using wireless communication has been reduced, which has also contributed to the rapid development of the Internet of Things industry. Power carrier communication uses a dedicated power carrier encoding and decoding module to perform two-way communication through AC cables.

[0006] Smart light pole sensing equipment, smart light poles can collect internal or external environmental data by adding environmental sensors. The sensors are connected to remote communication modules or transparent transmission modules to achieve remote data acquisition. Existing environmental sensor implementations are divided into device integration and independent installation. The device integration type is the form in which the controller inside the smart light pole is integrated into the controller or onboard sensor probe. The independent installation type is the installation of an independent environmental sensor inside the smart light pole, and the controller collects environmental sensor data through serial communication.

[0007] As a data concentration and information display interface, the smart light pole management platform can remotely manage data acquisition equipment, controlled equipment, and remote communication equipment. Data is collected at the edge, and graphic information is analyzed, sorted, and presented. The current status of the equipment and the object under test can be displayed as a whole, and historical curves can be drawn to show trend changes. It enables managers to obtain the operation status of remote equipment more intuitively, and the operation page can control the opening, closing, and status adjustment of remote equipment. At the same time, the control platform can connect to other management platforms for information sharing and realize multi-network interconnection. Most smart light tube management platforms can only perform remote data collection and presentation, command control, information release, asset management, equipment information registration authorization, etc.

[0008] The existing smart light pole control system is just a simple functional module implementation, such as the environmental data collection and reporting display module, the single light control module, the power test and metering reporting module, the alarm information reporting module, etc. The module functions are relatively independent, and the functions are just simple implementation functions. There is no overall planning of functions from the perspective of smart light poles to conduct closed-loop management of the light pole construction stage and the operation and maintenance stage. The specific technical defects are as follows:

[0009] 1. Environmental parameter collection. Existing smart light pole environmental sensors are integrated or independently installed. The integrated type can only test the internal parameters of the device or the surface parameters of the device, and cannot reflect the internal status of the smart light pole. Since the integrated sensor components are independent of each other and integrated on the controller board, this limits the detection distance of the sensor and cannot enter the environment to be tested completely independently. Affected by the temperature of the equipment, the measured temperature is high. At the same time, the sensor is led out from the inside of the equipment. It is difficult to meet the overall waterproof level requirements of the equipment inside the pole body. The potting treatment is not conducive to the heat dissipation and secondary maintenance of the equipment. It causes the project loss to become higher. Since the independent sensor is a self-contained product, the external wiring occupies the external interface resources of the product, which increases the interface of the controller product and the wiring, which is not conducive to the design requirements of miniaturization and lightweight of the product. The sensor design has a large sensor control part, and most of this type of sensor is made up of sensor components. It is not only large in size, but also low in integration. And when connecting to the controller, the interface mostly uses the terminal block form, which is not conducive to the overall waterproof design of the controller.

[0010] 2. At present, the smart light pole control system installs the equipment on the smart light pole, and then conducts platform docking and debugging after powering on and connecting to the network. Before the equipment is debugged and put online, the equipment does not manage the smart light pole in any way, and the smart light pole and the controller do not form a whole product. As a subsidiary product of the smart light pole, the controller is out of the scope of the smart light pole and consists of two parts: the street light pole and the controller. If it does not play a good auxiliary role in the construction process of the smart light pole, it cannot reflect the intelligent characteristics of the new generation of light pole products. At the same time, the traceability of the smart light pole cannot be achieved during the construction process of the smart light pole.

[0011] 3. During the operation and maintenance stage of smart lamp poles, the pole body, lamp head, controller, sensor, mounting equipment, etc. are managed as independent hardware equipment or facilities. At present, the equipment is manually bound to each other during installation, and the equipment and facilities are managed by uploading or manually registering the longitude and latitude measured on the spot to the platform. Equipment failure is reported to the platform by the equipment abnormality, and the maintenance instructions are issued by the personnel or the platform to the operation and maintenance unit. After the equipment and pole body corresponding to the abnormal problem are clearly marked, the operation and maintenance personnel will conduct on-site search and repair and handle the problem according to the map. Simple problems such as equipment damage, abnormal street lights, water ingress to the pole body, and tilt of the pole body can be viewed on site, and the problem can be located, and the accessories can be coordinated for replacement. After the operation and maintenance work is completed, manual feedback results are required, or the processing results are manually submitted on the mobile terminal to complete the operation and maintenance work. This has caused a large workload for the operation and maintenance personnel, negligence of the operation and maintenance personnel, and is not conducive to closed-loop management.

[0012] 4. In terms of lighting time strategy, the existing lighting control method adopts an open 24-hour system that can be set arbitrarily. Using this method to set the time for the whole year is cumbersome and the timetable storage data volume is large. If only short-term time control parameters are stored, the control strategy is single and not very versatile. It cannot meet the multi-mode application scenarios of street lights in certain areas. Manual temporary adjustments are required frequently to ensure the lighting plan at a specific time in advance. Repeated and frequent adjustments to time control will greatly increase maintenance costs and are not conducive to the stable implementation of energy-saving metering work.

[0013] In summary, in the construction and use of smart light poles, the pole body, controller, sensor and platform module function as independent individuals, which cannot achieve equipment linkage and overall system management. This makes it impossible for smart light poles to reflect the effectiveness of smart construction and smart operation and maintenance. Summary of the invention

[0014] The purpose of the present invention is to provide a smart lamp pole control system and method to solve the management problem of the smart lamp pole throughout its life cycle.

[0015] The present invention provides a smart lamp pole control system.

[0016] It includes a core controller, an all-in-one sensor, a first illumination sensor module, a second illumination sensor module, an LED street light source module, and a smart lamp pole management platform. The all-in-one sensor, the first illumination sensor module, the second illumination sensor module, and the LED street light source module are connected to the core controller; the core controller and the all-in-one sensor are installed inside the lamp pole; the first illumination sensor module is installed on the back of the street lamp head to sense the ambient illumination; the second illumination sensor module is installed on the lamp shell of the light-emitting surface of the light source module to sense the street lamp illumination; the all-in-one sensor is used to collect environmental data inside the lamp pole, including temperature, humidity, illumination, and water immersion;

[0017] The smart lamp pole management platform includes a main platform and an auxiliary platform, the core controller is connected to the main platform through a switch and a first 4G link, and the core controller is connected to the auxiliary platform through a second 4G link; the main platform communicates with the mobile terminal;

[0018] The core controller is used to control the switch and brightness of the street lamp; the LED street lamp light source module cooperates with the first illumination sensor module for auxiliary control.

[0019] The present invention also provides a smart lamp pole control method using the smart lamp pole control system, comprising:

[0020] The core controller has 36 sets of sunrise and sunset time sampling tables built in. Through GPS timing information, it compares and determines whether the current date is between two adjacent dates, and calculates the sunrise and sunset time of the current date;

[0021] The core controller presets 4 nighttime dimming schemes, with a cycle between sunset and sunrise the next day. The time is divided into time periods, and the corresponding lamp head dimming settings are made for each time period. After the execution scheme is selected, the street lamp automatically operates according to the preset scheme;

[0022] Four different night dimming schemes are used to implement summer and winter urban municipal lighting. During the execution of the daily night dimming scheme, if there is a need to adjust the night plan on a temporary or special date without affecting the normal dimming scheme execution on other dates, the core controller is set with a special date to execute a special dimming scheme.

[0023] After the device has executed the special date for a single day, it determines whether the subsequent date is a special date. If not, the daily night dimming plan is executed. If it is still a special date, the special dimming plan is still executed.

[0024] Furthermore, the method further comprises:

[0025] The core controller uses the preset upper and lower illumination thresholds to determine whether temporary lighting is required, including early lighting on rainy days.

[0026] When the core controller determines that the time is within the non-lighting period, the illuminance is collected at a fixed time. When the collected illuminance value is lower than the set illuminance lower limit threshold, the collection frequency is increased. When it is determined that the collected illuminance values ​​are lower than the illuminance lower limit threshold for three consecutive times, the street light switch is turned on and the street light brightness value is adjusted to 50%;

[0027] When the illuminance collected by the first illuminance sensor module on the back of the street lamp head is higher than the upper illuminance threshold preset by the core controller, the street light switch is turned off and the daily night dimming plan is entered. If the street light is turned on in advance, after sunset, the street light will perform dimming control according to the daily night dimming plan and will no longer be controlled by the illuminance sensor on the back of the street lamp head.

[0028] Furthermore, the method further comprises:

[0029] The core controller conducts online verification of the equipment platform before leaving the factory. After the platform receives the environmental parameter data packet and power metering data packet sent with the device ID in a standard format, the platform automatically registers. During the construction of smart light poles, the platform displays the status information of the equipment and smart light poles in three stages, namely: registered, installed, and enabled.

[0030] Furthermore, the method further comprises:

[0031] After the core controller is powered on for the first time, it sends location coordinate information to the platform every 10 minutes when the mains power is connected. After the core controller test, energy metering calibration, and tilt calibration are completed, the platform is connected and the status information changes to registered. When the power is off, the core controller enters sleep mode and uses the built-in battery to perform a daily report and send location and status information to the platform.

[0032] The core controller is installed inside the smart light pole and shipped as a whole. The location information reported daily records the logistics location trajectory of the smart light pole. The installation state of the core controller when the light pole is upright is recorded as zero point.

[0033] After the core controller is installed inside the pole body, the tilt parameters collected daily during storage and transportation will exceed the set threshold. At this time, the tilt alarm is activated and sent to the remote platform along with the daily reported parameters;

[0034] After the smart light pole arrives at the installation site and is hoisted, the core controller will clear the tilt alarm when it identifies that the tilt parameter is within the preset threshold during daily parameter collection. At this time, the platform records the start time of tilt recovery. When the tilt parameter is within the threshold for three consecutive days, the platform changes the smart light pole status to installed.

[0035] When the smart light pole is installed and powered on, the core controller stably reports the collected status information once every 10 minutes; at night, the street lights are controlled by the core controller and the power parameters are collected. When the platform determines that the street light dimming brightness is 100%, and the collected street light current measurement value is greater than or equal to 0.2A, it means that the core controller has been normally enabled and started daily lighting control. At this time, the platform changes the smart light pole status to enabled; after the smart light pole is changed to enabled, the platform issues an instruction to modify the core controller reporting mode. When the mains is connected, the core controller reports data at a frequency of 10 minutes. The reported information includes: location information, internal environmental parameters of the light pole, water immersion conditions, hatch monitoring, and power metering.

[0036] Furthermore, the method further comprises:

[0037] During the operation and maintenance stage of the lamp pole, the core controller collects the temperature and humidity inside the smart lamp pole, water immersion, hatch status, pole tilt status, street light voltage, street light current, street light power, and electricity metering information, and presents it in the form of data and charts on the platform.

[0038] Furthermore, the method further comprises:

[0039] The temperature and humidity inside the pole cabin of the smart lamp pole are monitored through the fault alarm module. The platform remotely sets the temperature and humidity thresholds and recovery values ​​of the core controller according to the operating temperature and humidity of sensitive equipment inside the pole cabin. When the temperature or humidity in the cabin exceeds the set value, the core controller immediately reports the alarm information to the remote control platform.

[0040] Furthermore, the method further comprises:

[0041] Through the operation and maintenance link, the smart light pole can quickly locate and handle the problem after a fault occurs, and form a closed-loop operation and maintenance work through parameter collection, status upload, and platform work order flow of the core controller, including:

[0042] After the smart light pole issues an alarm, the platform determines the type of alarm information. When a temperature and humidity alarm is issued, the platform will prioritize synchronizing the outdoor temperature and humidity values ​​sent back by the distributed meteorological sensors installed on the outside of the smart light pole. If the humidity value sent back by the meteorological sensor on a rainy day exceeds the set threshold, the platform will cancel the alarm information; if the humidity value sent back by the meteorological sensor does not exceed the set threshold, the fan inside the pole cabin will be started synchronously to form a linkage, and active cooling will be used to dissipate heat and dehumidify. If the temperature and humidity values ​​cannot be restored to normal after the active cooling and dehumidification operations are continued for more than 15 minutes, the platform will generate an operation and maintenance work order and send it to the operation and maintenance department for on-site processing;

[0043] The core controller has a built-in six-axis sensor to monitor the tilt state of the pole. The tilt state is calibrated when the device leaves the factory. The tilt threshold is set through the platform during the use of the smart light pole. When the smart light pole encounters a tilt state, the six-axis sensor of the core controller calculates the tilt angle and uploads it to the platform, and reports the tilt alarm information at the same time. In the tilt alarm state, the alarm information is repeatedly fed back to the platform at intervals of 10 minutes until the alarm information is cleared after the tilt is restored; if the tilt alarm continues for more than 1 hour, or the tilt alarm value is greater than 10 degrees, the platform will generate an operation and maintenance work order and send it to the operation and maintenance department for on-site problem troubleshooting;

[0044] The second illumination sensor module on the front of the street lamp is used to automatically inspect the street lamp. The core controller monitors the voltage of the street lamp. When the voltage of the street lamp is lower than 175V, which affects the normal operation of the street lamp, an undervoltage alarm is reported. At the same time, when the street lamp dimming parameter is greater than 20% under normal voltage, and the actual measured value of the street lamp current is less than the set threshold, the core controller reports a street lamp fault alarm.

[0045] The light-sensitive component of the multi-in-one sensor inside the light pole and the core controller monitors the state of the smart light pole hatch in real time. When the hatch is closed, the light monitoring value of the light-sensitive component is lower than the threshold, and the core controller feedbacks the platform hatch state as closed; when the hatch is open, after the outside light enters the light pole cabin, when the light monitoring value of the light-sensitive component is higher than the set threshold, the core controller feedbacks the platform hatch state as open and pushes the hatch opening alarm information to the remote platform;

[0046] During the normal operation of the smart light pole control system, the platform generates a corresponding operation and maintenance work order for the reported alarm information and sends it to the operation and maintenance department. The alarm information includes: alarm time, alarm type, alarm threshold, alarm parameters, and real-time location information reported by the core controller; after the hatch of the smart light pole is opened, the photosensitive component of the core controller's all-in-one sensor detects that the external illumination value exceeds the set threshold, and reports the hatch alarm information through the core controller. After receiving the alarm information of the hatch opening, the platform changes the operation and maintenance status to the arrival of the operation and maintenance personnel; after the on-site operation and maintenance personnel close the hatch of the smart light pole, the photosensitive component of the core controller's all-in-one sensor detects that the external illumination value is lower than the set threshold, clears the hatch opening alarm, and reports the status information that the hatch is closed. At this time, the platform recognizes the hatch closing information and changes the operation and maintenance status information to the end of the work order.

[0047] Furthermore, the method further comprises:

[0048] During use, the smart lamp pole control system collects street lamp current, voltage, power, power factor and electric energy accumulation parameters in real time through the metering module of the core controller, monitors the energy consumption of the smart lamp pole, and reports to the remote management platform through 4G communication for recording and statistics; the platform energy efficiency module queries the street lamp control strategy to obtain the currently executed lighting control strategy; when the street lamp is in normal working state, the core controller collects the street lamp current, voltage, power, power factor and electric energy and reports to the platform for data storage; the platform calculates the daily street lamp energy consumption results based on the actual electric energy value used, and intelligently generates the energy consumption difference between the newly set strategy and the original strategy in the strategy adjustment interface, which is used to guide the street lamp strategy adjustment and energy consumption statistics.

[0049] Furthermore, the method further comprises:

[0050] The core controller supports dual-channel server management and single-channel data monitoring on the communication link; the core controller sets the IP and port configuration of the two servers on the 4G wireless communication link, and the dual-server platform uploads collected data, sets remote parameters, issues lighting control strategies, and identifies alarm information through the communication protocol; the core controller uses RJ45 wired communication for one-way data reporting, data monitoring, and alarm information identification.

[0051] Through the above solution, through the smart lamp pole control system and method, the entire life cycle of the smart lamp pole can be managed, and independent equipment, platforms, construction, and operation and maintenance can be organically combined.

[0052] The above description is only an overview of the technical solution of the present invention.

[0059] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0060] Ginseng Figure 1 , Figure 2 , Figure 6 As shown, this embodiment provides a smart lamp pole control system, including a core controller 1, an all-in-one sensor 2, a first illuminance sensor module 3, a second illuminance sensor module 4, an LED street light source module, and a smart lamp pole management platform. The all-in-one sensor 1, the first illuminance sensor module 3, the second illuminance sensor module 4, and the LED street light source module are connected to the core controller 1; the core controller 1 and the all-in-one sensor 2 are installed inside the lamp pole; the first illuminance sensor module 3 is installed on the back of the street lamp head for sensing the ambient illuminance; the second illuminance sensor module Block 4 is installed on the lamp shell of the light-emitting surface of the light source module, and is used to sense the illumination of the street lamp; the all-in-one sensor 2 is used to collect internal environmental data of the lamp pole, including temperature, humidity, illumination, and water immersion; the smart lamp pole management platform includes a main platform and an auxiliary platform, the core controller 1 is connected to the main platform through a switch and a first 4G link, and the core controller is connected to the auxiliary platform through a second 4G link; the main platform communicates with the mobile terminal; the core controller 1 is used to control the switch and brightness of the street lamp; the LED street lamp light source module and the first illumination sensor module 3 are used for auxiliary control.

[0061] The control method of the smart light pole control system is as follows:

[0062] 1. Time control

[0063] Ginseng Figure 3 As shown, the core controller is used to control the switch and brightness of the street lamp, and the light source module is matched with the first illumination sensor module 3 for auxiliary control. The core controller internally stores 36 sets of sunrise and sunset time sampling tables, and compares and judges whether the current date is between two adjacent dates through GPS timing information. Since the sunrise and sunset times change slightly every day, the current date offset can be increased or decreased by using two sets of adjacent data to accurately calculate the sunrise and sunset times of the current date. The core controller lighting control can also preset 4 night dimming schemes, the cycle is between sunset time and sunrise time of the next day, the time during the period can be divided into time periods, and the corresponding lamp head dimming settings can be made for each time period. After selecting the execution plan, the street lamp automatically runs according to the predetermined plan, and no manual operation and maintenance and intervention are required. The 4 different night dimming schemes can meet the different choices of urban municipal lighting in summer and winter. During the execution of the daily night dimming scheme, if there is a need to adjust the night plan on a temporary or special date and it does not affect the normal dimming scheme execution on other dates, the core controller can be set with a special date to execute the special dimming scheme. After the device has executed the special date for a single day, it determines whether the subsequent date is a special date. If not, the daily night dimming plan is executed. If it is still a special date, the special dimming plan is still executed.

[0064] The core controller can not only support 12-hour lighting power supply, but also 24-hour lighting power supply. It can turn on the light in advance on rainy days. The first illuminance sensor module 3 on the back of the street lamp head can sense the ambient illuminance and judge whether it is necessary to temporarily turn on the light through the upper and lower illuminance thresholds preset by the core controller. The sensor is connected to the RS485 interface of the core controller. When the core controller determines that the time is in the non-lighting time period, the illuminance is collected at a fixed time. When the collected illuminance value is lower than the set illuminance lower limit threshold, the collection frequency will be increased. When the system determines that the collected illuminance values ​​are lower than the illuminance lower limit threshold for three consecutive times, the street lamp switch is turned on and the street lamp brightness value is adjusted to 50%. When the illuminance collected by the illuminance sensor on the back of the street lamp head is higher than the illuminance upper limit threshold preset by the core controller, the street lamp switch is turned off and the daily night dimming scheme is entered. If the street lamp is turned on in advance, after the time enters the sunset time, the street lamp performs dimming control according to the daily night dimming scheme and is no longer controlled by the first illuminance sensor module 3 on the back of the street lamp head.

[0065] 2. Equipment delivery, construction period and testing

[0066] Ginseng Figure 4As shown in the figure, the smart light pole control system can monitor the entire process of smart light poles from the equipment factory test stage to the completion of smart light pole installation. The core controller verifies the equipment platform online at the time of leaving the factory. After the platform receives the environmental parameter data packet and power metering data packet sent by the device ID with a standard format, the platform automatically registers, eliminating the need for platform registration and form filling. The platform displays the status information of the equipment and smart light poles in three stages during the construction of smart light poles, namely: registered, installed, and enabled.

[0067] After the core controller is powered on for the first time, the core controller sends the location coordinate information to the platform every 10 minutes when it is connected to the mains. After the core controller test, energy metering calibration, and tilt calibration are completed, the platform is connected and the status information changes to registered. In the power-off state, the core controller will enter the sleep mode, use the built-in 18650 battery to make a daily report once a day, and send the location and status information to the platform. The built-in 18650 battery can maintain the data reporting of the device for 45 days in the power-off state. The core controller is installed inside the smart light pole as a whole for factory transportation. The location information reported every day can record the logistics location trajectory of the smart light pole, which is convenient for traceability management. The core controller tilt must be calibrated before the smart light pole leaves the factory, and the calibration takes the installation state of the core controller in the upright state of the light pole as the zero point. After the smart light pole is produced and the equipment is installed inside the pole body, the tilt parameters collected daily during storage and transportation will exceed the set threshold. At this time, the tilt alarm will be activated and sent to the remote platform together with the daily reported parameters. After the smart light pole arrives at the installation site and the light pole is hoisted, the tilt alarm will be cleared when the core controller identifies that the tilt parameter is within the preset threshold range during the daily parameter collection process. At this time, the platform will record the start time of tilt recovery. When the tilt parameter is within the threshold range for three consecutive days, the platform changes the status of the smart light pole to installed. When the smart light pole is installed and powered on, the core controller stably reports the collected status information once every 10 minutes. At night, when the street light is controlled by the core controller and the power parameters are collected, the platform determines that when the street light dimming brightness is 100%, the collected street light current measurement value is greater than or equal to 0.2A, which means that the core controller has been normally enabled and started daily lighting control. At this time, the platform changes the status of the smart light pole to enabled. After the smart light pole is enabled, the platform issues a command to modify the reporting mode of the core controller. When the mains is connected, the core controller reports data at a frequency of 10 minutes. The reported information includes: location information, internal environmental parameters of the light pole, flooding conditions, hatch monitoring, power metering and other parameters. In the event of a power outage, the built-in 18650 battery can maintain data reporting for 6 hours a day, meeting daily usage needs.

[0068] 3. Fault alarm, operation and maintenance guidance, automatic street light inspection, remote upgrade

[0069] Ginseng Figure 5 As described above, the smart lamp pole control system can monitor the status information of the smart lamp pole in real time during the operation and maintenance stage. Through the core controller, the temperature and humidity inside the smart lamp pole, water immersion, door status, pole tilt status, street light voltage, street light current, street light power, electricity metering and other status information are collected and presented in the form of data and charts on the platform.

[0070] The smart light pole control system can monitor the temperature and humidity inside the smart light pole cabin through the fault alarm module. The platform can remotely set the temperature and humidity thresholds and recovery values ​​of the core controller according to the temperature and humidity of the sensitive equipment inside the cabin. When the temperature or humidity in the cabin exceeds the set value, the core controller will immediately report the alarm information to the remote control platform. The smart light pole control system provides an operation and maintenance link during the use of the smart light pole, so that the smart light pole can locate and handle problems more quickly after the line failure, and can form a closed-loop operation and maintenance work through the core controller's parameter collection, status upload, and platform work order flow. First, after the smart light pole alarms, the platform determines the type of alarm information. When the temperature and humidity alarm is issued, the distributed meteorological sensor installed on the outside of the smart light pole body will be synchronized first to transmit the outdoor temperature and humidity values. If the humidity value transmitted by the meteorological sensor installed on the outside of the pole body on a rainy day exceeds the set threshold, the platform cancels the alarm information. If the humidity value sent back by the meteorological sensor installed on the outside of the pole body does not exceed the set threshold on a non-rainy day, the fan inside the pole cabin will be started synchronously to form a linkage, and active cooling will be used to dissipate heat and remove moisture. After the active cooling and dehumidification operations continue for more than 15 minutes, if the temperature and humidity values ​​still cannot be restored to normal, the platform will generate an operation and maintenance work order and send it to the operation and maintenance department for on-site processing.

[0071] The smart light pole control system uses the six-axis sensor built into the core controller of the light pole to monitor the tilt state of the pole. The tilt state is calibrated when the equipment leaves the factory. The tilt threshold is set through the platform during the use of the smart light pole. When the smart light pole encounters a tilt condition, the six-axis sensor of the core controller will calculate the tilt angle and upload it to the platform, and report the tilt alarm information at the same time. In the tilt alarm state, the device will repeatedly feedback the alarm information to the platform at intervals of 10 minutes until the alarm information is cleared after the tilt is restored. If the device continues to tilt alarm for more than 1 hour, or the tilt alarm value is greater than 10 degrees, the platform will generate an operation and maintenance work order and send it to the operation and maintenance department for on-site problem troubleshooting.

[0072] The smart lamp pole control system has the function of automatic street lamp inspection. The automatic street lamp inspection uses the second illumination sensor module 4 on the front of the street lamp to perform automatic street lamp inspection. The core controller monitors the street lamp voltage. When the street lamp voltage is lower than 175V, which affects the normal operation of the street lamp, it reports an undervoltage alarm. At the same time, when it is judged that under normal voltage, when the street lamp dimming parameter is greater than 20%, the actual street lamp current measured value is less than a certain threshold value, the core controller reports a street lamp fault alarm. The specific threshold value is based on the parameters issued by the platform and is suitable for the actual use of street lamps with different powers.

[0073] The smart light pole control system can monitor the status of the smart light pole hatch in real time. The photosensitive component of the all-in-one sensor that comes with the core controller inside the light pole can be installed inside the light pole hatch. When the hatch is closed, the light monitoring value of the photosensitive component is lower than the threshold. At this time, the core controller feedbacks the platform hatch status as closed. When the hatch is open, after the outside light enters the light pole hatch, when the light monitoring value of the photosensitive component is higher than the set threshold, the core controller feedbacks the platform hatch status as open and pushes the hatch opening alarm information to the remote platform.

[0074] During the normal operation of the smart light pole control system, the platform generates a corresponding operation and maintenance work order for the reported alarm information and sends it to the operation and maintenance department. The alarm information includes: alarm time, alarm type, alarm threshold, alarm parameters, and real-time location reported by the core controller. After receiving the operation and maintenance work order, the operation and maintenance personnel can confirm the approximate location according to the location coordinates of the core controller displayed on the mobile APP, and go to the site to handle the problem. After the operation and maintenance personnel arrive at the designated location, they will open the cabin. After the hatch of the smart light pole is opened, the photosensitive component of the multi-in-one sensor of the core controller detects that the external illumination value exceeds the set threshold, and the hatch alarm information will be reported through the core controller. After receiving the alarm information of the hatch opening, the platform changes the operation and maintenance status display from "work order has been issued" to "operation and maintenance personnel are on site". At this time, the operation and maintenance personnel can confirm and investigate the abnormal situation of the equipment. After handling the problem, the corresponding work order alarm parameters will return to normal, and the platform operation and maintenance status will display "handled". After the on-site maintenance personnel close the hatch of the smart light pole, the photosensitive component of the core controller's all-in-one sensor detects that the external illumination value is lower than the set threshold, clears the hatch opening alarm, and reports the status information as the hatch is closed. At this time, the platform recognizes the hatch closing information and changes the status information to "work order completed".

[0075] The relevant parameters and information provided by each functional component of the smart light pole control system connects all stages of the entire operation and maintenance business status change, providing real-time data for the operation and maintenance service platform to track the equipment status.

[0076] 4. Energy efficiency monitoring and data hosting services

[0077] During the use of the smart light pole control system, the metering module of the core controller can collect street lamp current, voltage, power, power factor and accumulated electric energy parameters in real time. The energy consumption of the smart light pole is monitored and reported to the remote management platform through 4G communication for recording and statistics. The platform energy efficiency module obtains the currently executed light control strategy by querying the street light control strategy. When the street light is in normal working condition, the core controller collects the street light current, voltage, power, power factor and electric energy and reports to the platform for data storage. The platform can calculate the daily street light energy consumption results based on the actual electric energy value used, and intelligently generate the energy consumption difference between the newly set strategy and the original strategy in the strategy adjustment interface. It is used to guide the street light strategy adjustment and energy consumption statistics.

[0078] The core controller supports dual-channel server management and single-channel data monitoring on the communication link. The core controller can set the IP and port configuration of two servers on the 4G wireless communication link. The dual-server platform can upload collected data, set remote parameters, issue lighting control strategies, and identify alarm information through communication protocols. The core controller can also use RJ45 wired communication for one-way data reporting, data monitoring, alarm information identification and other one-way data acquisition services.

[0079] The smart light pole control system designs the core controller as an accessory product of the smart light pole, which can be activated and put online when the light pole is produced, and can monitor the location and status information of the smart light pole and upload it, so that the smart light pole has digital life when it is produced. In terms of environmental data collection, a fully waterproof multi-in-one sensor is creatively designed to make the sensor a complete set of accessories for the controller, which not only solves the problem of inaccurate detection of environmental sensors, but also solves the problem of waterproofing of the whole machine. At the same time, it has strong versatility and can be replaced as an accessory. At the same time, it takes into account the low power consumption mode, so that the power consumption of the sensor is reduced to 20 milliwatts when working, and the dormant state does not consume electricity, and it can be activated again. In terms of lighting control, the core controller obtains GPS longitude and latitude, performs time correction by presetting the sunrise and sunset schedule, and combines the illumination sensor on the street lamp to supplement the judgment of the time of turning on and off the lights. The single-day time control is nested with the seasonal control to change the lighting strategy in winter and summer nights. Supports two sets of temporary time cycle settings to facilitate the guarantee of temporary activities at night. At the same time, the alarm function, location acquisition function, platform work order issuance function, etc. of the core controller form linkage, and multiple methods are used to lock fault problems and equipment locations, which facilitates closed-loop management. The specific technical effects include the following:

[0080] 1) In the smart light pole construction project, the production and transportation of smart light poles rely on the progress information provided by the smart light pole manufacturers, or the construction party needs to send personnel to supervise the construction on site to understand the production and logistics progress of smart light poles and supporting equipment in real time. Coordinate the construction unit to prepare for construction. When the delivery time planned by the light pole manufacturer cannot be delivered on time, the manufacturer will use the logistics company to delay the delivery time. And when shipping, due to the particularity of its goods, smart light poles require special logistics for loading and transportation. The construction party cannot obtain the arrival time of the light poles in real time through logistics information, so it is impossible to predict the installation date of the smart light poles. This causes the construction personnel to work idle, and after the planned light poles arrive, it is necessary to arrange a warehouse for temporary storage, and then coordinate the construction personnel to install on a selected day. Not only does it cause a waste of personnel costs, but it also increases the storage costs of smart light poles. The smart light pole control system involved in the present invention can obtain offline position and report data without external mains power through the core controller equipped with the smart light poles at the factory, and report 1-2 times a day on a regular basis. The platform can track the logistics information of smart light poles, predict the arrival time of goods, and organize construction personnel to install them on site in advance. It facilitates the tracking and management of smart light poles. It is calculated that the core controller can maintain 45 days of effective daily data without external mains power. The time can cover the entire construction period. When connected to the mains power, the core controller automatically switches the reporting status to every 10 minutes.

[0081] 2) The smart light pole control system can accurately measure energy consumption. Most of the controllers and management platforms on the smart light poles on the market can only measure the real-time power parameters of the lighting fixtures on the road and record the power used. The control of smart street lights can only be configured for time period dimming, or the platform issues dimming instructions. This makes it difficult to meet the needs of long-term hosting, and the dimming strategy is single, resulting in problems such as unreasonable use of energy. It is impossible to intelligently save energy for street lights. At the same time, it is impossible to conduct in-depth research on urban lighting solutions. The smart light pole control system involved in the present invention formulates different strategies for four time periods every day through the platform and executes them according to the strategy. In different months, different strategies can also be selected and executed according to the sunshine time. The strategy is formulated and issued at one time, so that the equipment has different street light control strategies to execute throughout the year. Special lighting control strategies can also adapt to temporary adjustment needs without disrupting the operation of the strategy throughout the year. At the same time, when the strategy changes, the platform can simulate and calculate the power consumption every night through the different illumination and dimming markets of each strategy. Thereby inferring the comparison of energy consumption when the strategy changes. It is convenient for users to have an intuitive judgment on energy consumption in the strategy setting stage.

[0082] 3) Most of the existing smart light pole products have an alarm function, but the alarm function is a single independent function, which only displays the fault locally or sends it to a remote platform. The lack of logical judgment ability on the device side is not conducive to the operation and maintenance personnel to locate and troubleshoot problems. The operation and maintenance workload of smart light poles is greatly increased and the efficiency is reduced. Smart light poles cannot play a linkage effect and cannot be closely integrated with actual business, so that the functional module becomes a single device or sensor, and cannot form a smart light pole control system. The smart light pole control system involved in the present invention can not only serve the construction work in the construction phase, but also mobilize all the functions of the core controller and its all-in-one sensor to serve the operation and maintenance of smart light poles in the operation and maintenance phase, so that every step of the operation and maintenance phase is standardized, and the platform and personnel operations are linked, with strong work traceability. At the same time, the state change of the operation and maintenance module can also remind the operation and maintenance personnel to perform the next operation, so that they can follow the instructions in the process. The platform can also track the work order accurately to every link. The work of communication between the operation and maintenance personnel and the central control dispatching staff is reduced, making the business smoother. Improve work efficiency, that is, reduce operation and maintenance costs.

[0083] 4) Most of the smart lamp pole controllers are single-platform communication. This form simplifies the communication link, but as more and more IoT devices are connected to the network, it may affect the communication quality. At this time, the device often loses connection when encountering communication problems. When the wireless communication is lost, the platform cannot establish a link with the device again, and can only wait for the device to actively connect to the platform. The present invention uses a 4G communication chip to establish a dual-server connection. The communication main control chip uses a single serial port to connect to two servers at the same time. When reporting data, the message is marked and sent to a certain link. When the device receives data, it does not distinguish whether it comes from a certain link. This form not only saves chip pin resources, but also supports the sending and receiving of dual-channel servers. The dual platforms simultaneously perform parameter settings, command issuance and other operations on the device. At the same time, the device can also send the environment and power collection parameters, location information, and heartbeat messages of the core controller to the dual platforms. The dual platform function can support users to carry out data hosting services and maintenance work. The main platform is used for customer display and operation, and the auxiliary platform is used for daily management of the platform and equipment. It solves the problems of limited platform access and platform freeze caused by multiple users operating one platform.

[0084] 5) The core controller of the present invention switches the mode of reporting data during the construction period and the use period. The core controller uses a built-in 18650 battery, shuts down peripheral modules, functional chips, etc., and only maintains its own timing program to achieve a low power consumption mode. It can achieve 45 days of standby operation without external mains power. After the timing ends, the MCU is reset to run the acquisition program, and the standby mode is entered again after reporting the parameters.

[0085] 6) The energy consumption prediction function of the lighting control strategy of the smart light pole control system involved in the present invention. The lighting control strategy and power parameters fed back by the core controller are used to simulate the energy consumption comparison after the strategy is modified. This is used to guide the formulation of the lighting control strategy.

[0086] 7) The operation and maintenance management process of the smart lamp pole control system involved in the present invention. The all-in-one sensor of the core controller is used to collect parameter and status information, and the feedback platform determines the progress of the operation and maintenance work to achieve intelligent operation and maintenance.

[0087] 8) The dual-platform service function of the smart lamp pole control system of the present invention can support the management function of dual links, realize data hosting and platform and equipment maintenance services.

[0088] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
