Referring to fig. 1, fig. 1 is a schematic implementation flow chart of a street lamp control method according to an embodiment of the present application. The street lamp control method is applied to a street lamp control system. The street lamp control system comprises a server and a plurality of street lamps, wherein each street lamp comprises a street lamp controller, and the server is respectively in communication connection with each street lamp through a public network.

Exemplary, as shown in fig. 2, fig. 2 is a schematic structural diagram of a street lamp control system according to an embodiment of the present application.

As can be seen from fig. 2, the street lamp control system 200 provided in the embodiment of the present application includes a server 201 and a plurality of street lamps 202. Each street lamp 202 includes a street lamp controller (the street lamp controller is not shown in the figure, in practical application, it may be disposed on a street lamp post according to a structure of the street lamp, or integrated at a street lamp cap portion, specifically, an installation position of the street lamp controller is not limited), and the server 201 is respectively connected with the plurality of street lamps 202 through a public network. Specifically, the public network is a 4G network. In the embodiment of the application, communication connection is established between the server 201 and the street lamps 202 through a 4G network, each street lamp controller is a 4G street lamp controller matched with a 4G internet of things card, and state data of each street lamp controller can be directly transmitted to the server 201 through the 4G network without data transfer.

It should be noted that each street lamp includes at least one 4G street lamp controller. The number of the 4G street lamp controllers is determined according to the number of lamp caps of the street lamp. For example, a single-cap street lamp includes a single 4G street lamp controller, a double-cap street lamp includes two 4G street lamp controllers, and so on. According to the embodiment of the application, the 4G internet of things card is directly embedded in the street lamp controller to form the 4G street lamp controller, the radio frequency and the baseband chip are integrated on the PCB small board through the 4G street lamp controller, the problem that a plurality of centralized managers are required to be built for a long distance in the existing street lamp control process is solved, the street lamp can be directly connected to the server through 4G network resources, and the direct management and control of the street lamp by the server are realized.

The server 201 is a cloud server, and is configured to respectively determine whether a communication network, such as a 4G network, between the street lamp controllers is normal, and when determining that the communication network is normal, send a control instruction to each street lamp controller in combination with a control policy configured in the cloud in advance to instruct each street lamp controller to control the state of each corresponding street lamp 202 based on the control instruction, based on the state data of the street lamp controller uploaded by each street lamp controller; or stopping sending a control instruction to the street lamp controller with abnormal communication network if the communication network is judged to be abnormal, and periodically or in real time sending a data acquisition instruction to the street lamp controller with abnormal communication network at preset time intervals so as to judge whether the communication network is recovered to be normal; the street lamp controller is configured to control the state of the corresponding street lamp 202 based on a control policy stored locally in advance when the communication network is abnormal. Specifically, the state of the street lamp includes at least one of an on state, an off state, and a brightness level.

Compared with the existing street lamp control technology, the street lamp control system provided by the embodiment of the application realizes that the 4G public network resource is linked to the cloud end through the 4G street lamp controller, solves the problem that a plurality of centralized managers are required to be built due to long data transmission distance, and can enable the street lamp controller to normally control the state of the street lamp when the network is abnormal by configuring the control strategy in the street lamp controller in advance, so that effective control of the street lamp is guaranteed, and potential safety hazards of data transmission due to network abnormality are further solved.

Referring to fig. 1, the street lamp control method includes steps S101 to S105. The details are as follows:

s101: the server judges whether the communication network between the server and each street lamp controller is normal or not respectively.

The server judges whether the communication network between the server and each street lamp controller is normal or not according to the received time interval of uploading data by each street lamp controller. For example, if the server does not receive the data uploaded by the street lamp controller within the preset time interval, the communication network is judged to be abnormal. Or the server periodically or in real time sends a data acquisition instruction to each street lamp controller at preset time intervals, and judges whether the communication network is normal or not according to the state of sending the data acquisition instruction and whether the data uploaded by each street lamp controller is acquired. For example, if the server periodically or in real time sends a data acquisition instruction to the street lamp controllers at a preset time interval, and then detects that the state of the data acquisition instruction is that the data uploaded by each street lamp controller is sent and received, the communication network is judged to be normal; if the state of the data acquisition instruction is not sent or the data uploaded by the partial street lamp controllers is not received, judging that the communication network with the partial street lamp controllers is abnormal. In addition, the server can also judge whether the communication network between the server and each street lamp controller is normal or not through a signal strength detection method or a data packet loss rate detection method. Specifically, after sending a data acquisition instruction to each street lamp controller, the server can receive data or a confirmation signal returned from each street lamp controller under the condition that the communication network is normal. Therefore, the server can detect the strength of the received signal in real time, and a stronger signal strength indicates that the communication network is better, and a weaker signal indicates that the communication network may have a problem. After periodically sending the data acquisition instruction to each street lamp controller, the server compares the data sending the data acquisition instruction with the data receiving the uploading data by recording the number of the data acquisition instruction sent and the number of the uploading data received, and calculates the data packet loss rate. A lower packet loss rate indicates a better communication network, while a higher packet loss rate indicates a communication network failure.

It should be noted that, the control of the server to each street lamp controller is independent, that is, if the server judges that the communication network with part of street lamp controllers is normal, a control instruction is issued to the part of street lamp controllers according to the communication network is normal; if the server judges that the communication network with other part of street lamp controllers is abnormal, the server issues a data acquisition instruction to the other part of street lamp controllers.

Specifically, the server judges whether the communication network with each street lamp controller is normal or not, issues a control instruction when the communication network with the street lamp controllers is normal, stops sending the control instruction to the street lamp controllers with abnormal communication network when the communication network with part of street lamp controllers is abnormal, and periodically or in real time sends a data acquisition instruction to the street lamp controllers with abnormal communication network at preset time intervals so as to judge whether the communication network is normal or not. In addition, the server can also generate a network abnormal state and ensure the work order to be displayed aiming at the street lamp controller with abnormal communication network, so that the potential safety hazard of data transmission caused by the network abnormality can be solved. The security work orders comprise work order numbers, street lamp position information, fault description information and the like. The work list number is a number for uniquely identifying the maintenance task or the fault repair task.

S102: if the server judges that the communication network is normal, based on the state data and the environment data of the street lamp controllers uploaded by the street lamp controllers, a control command is respectively sent to the street lamp controllers by combining a control strategy which is configured in the cloud in advance.

The data uploaded by the street lamp controller comprises state data and environment data of the street lamp controller. Specifically, the status data of the street lamp controller includes: and energy consumption information of the street lamp controller. The energy consumption information of the street lamp controller can indirectly reflect whether the corresponding street lamp is damaged, complex detection of the street lamp is not needed through the street lamp controller, and the efficiency of street lamp detection is improved.

Specifically, the energy consumption information of the street lamp controller is determined by the energy efficiency and the input electric energy of the street lamp controller. The energy efficiency of the street lamp controller refers to the proportion of useful energy output by the street lamp controller in a specific working state to input electric energy. The energy efficiency of the street lamp controller can be estimated or measured according to the test data or standard data of the street lamp controller under different load conditions. The input electric energy is the electric energy actually consumed by the street lamp controller in a specific use time, and can be calculated by measuring current and voltage. Illustratively, the energy consumption information of the street lamp controller is calculated by multiplying the energy efficiency of the street lamp controller by the input electric energy. The calculation mode can better consider the actual energy efficiency characteristics of the street lamp controller, the energy consumption difference under different load conditions and the performance of the street lamp controller under different working states. By using the energy efficiency of the street lamp controller as a correction factor of the energy consumption information of the street lamp controller, the energy consumption information of the street lamp controller can be predicted more accurately, and whether the corresponding street lamp is damaged can be reflected accurately. The measured current and voltage can be measured through a circuit connected with the street lamp controller, the measured current value and voltage value of the street lamp controller are obtained, and the input electric energy of the street lamp controller is reflected by the current value and voltage value of the street lamp controller. The circuit connected with the street lamp controller comprises a current metering circuit and a voltage metering circuit, and the input electric energy of the street lamp controller can be calculated by the load current value of the current metering circuit and the load voltage value of the voltage metering circuit.

The environment data comprises traffic data, people stream data, weather conditions, environment brightness and the like. Specifically, the lamp post of each street lamp is also provided with environment sensing equipment such as a monitoring camera or an illumination sensor, and the environment sensing equipment is in communication connection with the street lamp controller, sends collected environment data to the street lamp controller, and then sends the collected environment data to the server through the street lamp controller.

In an embodiment, based on the state data of the street lamp controllers uploaded by each street lamp controller, in combination with a pre-configured control policy, a control instruction is sent to each street lamp controller, respectively, including: aiming at the energy consumption information of any street lamp controller, if the energy consumption information of the street lamp controller meets the preset condition, a control instruction is sent to the street lamp controller based on the environment data and the control strategy; if the energy consumption information of the street lamp controller does not meet the preset conditions, displaying the state data of the street lamp controller through a preset interface and generating early warning information so as to prompt a worker to trigger a control instruction of the street lamp controller corresponding to the street lamp through an operation interface based on the energy consumption information of the street lamp controller.

According to the analysis, the server can respectively issue different control instructions to each street lamp controller according to the energy consumption information of the street lamp controller so as to realize issuing of a correspondingly adapted control strategy to each street lamp.

The energy consumption information of the street lamp controller meets the preset condition, so that the street lamp connected with the street lamp controller is free from damage risk, and the street lamp connected with the street lamp controller is free from damage risk or damaged.

Illustratively, determining whether the energy consumption information of the street lamp controller satisfies a preset condition includes: periodically receiving energy consumption information of the street lamp controller according to a preset time interval (for example, 1 to 5 minutes); if the number of times that the energy consumption information of the street lamp controller is larger than or equal to the preset excessively high energy consumption threshold is larger than the preset number of times (for example, 3 times), or if the number of times that the energy consumption information of the street lamp controller is smaller than or equal to the excessively low energy consumption threshold is larger than the preset number of times, judging that the energy consumption information of the street lamp controller does not meet the preset condition; otherwise, judging that the energy consumption information of the street lamp controller meets the preset condition. Whether the energy consumption information of the street lamp controller meets the excessively low energy consumption threshold or the excessively high energy consumption threshold or not can be judged accurately, whether the street lamp illumination state connected with the street lamp controller fails or not can be judged accurately, the street lamp controller is prevented from judging the street lamp illumination state through a complex flow, and the street lamp control efficiency is improved.

In one embodiment, a preconfigured control strategy includes: and (5) a time-division control strategy. Specifically, the time-division control strategy includes: according to the lighting requirements of different time periods, the off state and the on state of each street lamp and the corresponding brightness level in different preset control periods are configured. The switching and brightness of the street lamp can be flexibly controlled according to the lighting requirements of different time periods through the time-interval control strategy. The control strategy can adapt to different lighting requirements and energy-saving requirements, and improves the flexibility and the adjustability of the street lamp system.

In an embodiment, sending a control instruction to a corresponding street lamp controller based on the environmental data and the control policy includes: analyzing the environment data, and determining first state information and first brightness level of each street lamp corresponding to the environment data; if the first state information and the second state information corresponding to the street lamp are not matched, or if the first brightness level and the second brightness level corresponding to the street lamp are not matched, a control instruction is sent to the corresponding street lamp controller based on the first state information and the first brightness level; otherwise, according to the second state information and the second brightness level, a control instruction is sent to the corresponding street lamp controller. The second state is state information of the pre-configured streetlamp in a control period to which the current moment belongs, and the second brightness level is the brightness level of the pre-configured streetlamp in the control period to which the current moment belongs.

Specifically, analyzing the environmental data includes: and analyzing traffic data, people flow data, weather conditions and environment brightness based on a machine learning algorithm, and predicting first state information and first brightness level corresponding to the street lamp suitable for the corresponding environment. Wherein the first status information comprises an off-state or an on-state and the first brightness level comprises a percentage value of the illumination brightness. By using sensing equipment or data acquisition equipment (such as monitoring cameras/illumination sensors and the like) on the street lamp post, environmental data such as traffic data, people flow data, weather conditions, ambient brightness and the like are monitored in real time to obtain real-time environmental data, and then the real-time environmental data is analyzed by using a machine learning algorithm to predict an optimal street lamp brightness configuration scheme, and the brightness of each street lamp is automatically regulated according to preset illumination strategies in different time periods so as to meet the illumination requirements of the current environment.

In addition, in order to improve the control efficiency to the street lamp, can carry out the network deployment with each street lamp, obtain the street lamp network deployment, take the street lamp network deployment to carry out independent control to each street lamp in the network deployment again to improve street lamp management efficiency, and adjust illumination intensity in a flexible way according to specific demand, in order to realize energy-conservation and provide suitable lighting environment.

Specifically, before the first state information and the second state information corresponding to the street lamp are different, the method further includes: respectively determining the street lamp networking to which each street lamp belongs; based on the first status information and the first brightness level, sending a control instruction to each street lamp controller, including: based on the first state information and the first brightness level, respectively sending respective corresponding control strategies to different street lamp controllers in each street lamp networking. In order to realize the free control to each street lamp, it should be noted that one street lamp can also form a street lamp networking, and in the same street lamp networking, the control strategy corresponding to each street lamp can be different.

Specifically, the street lamp controllers of the street lamps are provided with identification information, the identification information is a specific number and is used for uniquely identifying the street lamp controllers, the street lamp controllers are supported to be freely grouped into groups or areas based on the identification information, a street lamp networking is correspondingly formed, and the control time periods of the street lamps in the street lamp networking are uniformly configured. Specifically, the street lamp networking mode includes grouping according to streets or areas, and grouping the street lamps according to the street or area so as to perform grouping management and control. The grouping mode can be divided according to geographic positions or administrative areas, so that the street lamps in the whole street or area can be conveniently managed and monitored in a centralized mode.

The street lamps with the same illumination requirement brightness and the same illumination time can be grouped according to different illumination brightness requirements in the same scene. Therefore, the brightness of the street lamp can be uniformly adjusted under the same scene, so that the lighting requirements of different areas or streets can be met. In addition to grouping according to illumination brightness requirements, the grouping can be freely and flexibly performed according to other special requirements. For example, the street lamps are flexibly grouped and managed according to the functions, positions or other special requirements of the street lamps, so that more refined control and management are realized.

After the street lamps are networked in the street lamp networking mode, the street lamp networking of each street lamp is determined, and then based on the first state information and the first brightness level, the street lamp networking is used as a unit, and the street lamp controllers corresponding to the street lamps in each street lamp networking are respectively sent with the adaptive control instructions, so that effective management and control of the street lamps can be realized. The grouping management can improve the management efficiency, and flexibly adjust the illumination brightness according to specific requirements so as to realize energy conservation and provide a proper illumination environment.

S103: and when the communication network is normal, each street lamp controller controls the state of each corresponding street lamp based on the control instruction issued by the server.

S104: if the server judges that the communication network is abnormal with any street lamp controller, stopping sending a control instruction to the street lamp controller with abnormal communication network, and periodically or in real time sending a data acquisition instruction to the street lamp controller with abnormal communication network at preset time intervals, so as to judge whether the communication network is recovered to be normal according to the state of sending the data acquisition instruction and whether the data of each street lamp controller is acquired.

The process of judging whether the communication network is normal or abnormal can be referred to the description of the previous steps, and will not be repeated here. After determining that the communication network is abnormal, a status abnormality indication may be generated, and a security work order may be generated to prompt a worker to perform detection of the corresponding communication network.

S105: when the communication network is abnormal, the street lamp controller controls the state of the corresponding street lamp based on the control strategy stored in the local in advance.

The control strategy pre-configured in each street lamp controller is a time-division control strategy, for example, 4 time-division control strategies, and different off or on states of each street lamp in different control time-division are configured, so that network abnormality such as network disconnection or network unavailability can be solved conveniently, the street lamp controller can still work normally, and the on-off and brightness of the street lamp are controlled according to the pre-configured time-division control strategies. Specifically, based on a pre-configured control strategy, the state of each street lamp is controlled, including: determining a control period to which the current moment belongs; acquiring second state information of each street lamp and second brightness level of each street lamp, which are pre-configured in a corresponding control period; and sending control instructions to each street lamp controller based on each second state information and each second brightness level. The control period may be preset according to the lighting requirement of the area where the street lamp is located, for example, the control period includes 4 time periods, which are 6 to 18 in the morning, 18 to 20 in the evening, 20 to 24 in the evening, 24 to 6 in the morning, and so on. The second state information includes an off state or an on state, and the second brightness level includes a percentage value of the illumination brightness.

It should be understood that the second state information of each street lamp and the second brightness level of each street lamp may be preset according to the lighting requirement of the area where each street lamp is located, for example, in a period from 6 a.m. to 18 a.m. time, according to the traffic flow and the requirement of the road type of the area where each street lamp is located, the second state information may be configured to be in an off state to save energy. In the period from 18 pm to 20 pm, according to the traffic flow of the area where each street lamp is located and the requirement of the road type for illumination, the second state information can be configured to be in an on state, the second brightness level comprises that the illumination brightness of the main road is 100%, the illumination brightness of the auxiliary road is 90%, and the illumination brightness of the urban road is 100%. In the period from 20 pm to 24 pm, according to the traffic flow and road type of the area where each street lamp is located, the second state information may be configured to be in an on state, and the second brightness level includes that the illumination brightness of the main road is 80%, the illumination brightness of the auxiliary road is 70%, and the illumination brightness of the urban road is 70%. In the period from 24 pm to 6 pm, according to the traffic flow and road type of the area where each street lamp is located, the second state information may be configured to be in an on state, and the second brightness level includes that the illumination brightness of the main road is 60%, the illumination brightness of the auxiliary road is 50%, and the illumination brightness of the urban road is 30%. In addition, according to traffic flow and lighting requirements of the areas where the street lamps are located, the pre-configured control strategy can be to perform lighting and the like in a mode of lighting the street lamps in different areas in different time periods. Specifically, the preconfigured control strategy is related to the lighting requirement of the area where the street lamp is located, and the control strategies corresponding to different areas can be the same or different, so that the street lamp can be flexibly controlled.
