Example 1

The utility model provides a street lamp control system.

Fig. 1 is a schematic diagram of a street lamp control system according to an embodiment of the present invention. As shown in fig. 1, the street lamp control system 10 may include: a server 11 and a first street light 12.

And the server 11 is configured to obtain a target adjustment parameter of the single lamp controller of the first street lamp 12.

In this embodiment, the server 11 may be a local server, one server, or multiple servers, and is configured to obtain a target adjustment parameter of the first lamp 12, where the target adjustment parameter may be a dimming parameter for performing dimming compensation on the first lamp 12.

Optionally, the server 11 of this embodiment obtains a first detection state of the single-lamp controller of the first street lamp 12, where the first detection state is a state where the single-lamp controller is currently located when detecting, is related to a local environment where the single-lamp controller is located, and may be a state where the single-lamp controller is interfered by an external interference source when detecting, for example, a detection state where the single-lamp controller is shielded by a shielding object, a detection state where a illuminance value frequently changes due to continuous irradiation of a high beam of a night vehicle, or a fault state, for example, a situation where the illuminance value of the illuminance sensor is seriously distorted, and no limitation is made here. Optionally, when the single lamp controller of the first street lamp 12 is interfered by an external source, the illuminance value of the street lamp light source detected by the single lamp controller will be changed greatly, and since the single lamp controller has a self-adaptive adjustment function, the operating state of the single lamp controller will also be changed, and then the single lamp controller reports the current illuminance value, the changed lamp state, and the identifier of the single lamp controller to the server 11 through wireless transmission.

Optionally, the server 11 of this embodiment may divide the single-lamp controllers of the multiple street lamps into one area according to the geographical positioning information, for example, the area where the single-lamp controllers of the multiple street lamps are located is determined by the geographical electronic fence, the signal range that can be covered by the wireless/wired network, the end node of the wiring, and the like, so as to form a single-lamp control system network, where multiple street lamps and their light sources may be installed in different areas, and the multiple street lamps may be installed in a preset fixed manner, sometimes may be continuously installed, for example, the multiple street lamps are installed at equal intervals according to a road guidance manner set by the electronic geographical fence. Optionally, the single lamp controller of the street lamp of this embodiment obtains the location of the area where the single lamp controller of the street lamp is located through the device code.

The first street lamp 12 of this embodiment is located in the target area, and the target environment state of the target area is an overall state of the natural environment of the target area, and may include the illuminance of the natural environment, and may be determined by the illuminance value of the single lamp controller in which the surrounding detection state is normal. The server 11 determines whether the first detection state matches the target environment state of the target area where the first street lamp 12 is located, that is, whether the environment state corresponding to the first detection state matches the target environment state, for example, if the single lamp controller of the first street lamp 12 is shielded by a shielding object, the local environment illuminance where the single lamp controller is located is weak, and the target environment state of the target area is daytime and sufficient in illumination, the environment state corresponding to the first detection state does not match the target environment state, and the first detection state does not match the target environment state.

In the case where the server 11 detects that the first detection state does not match the target environment state, it determines that the first detection state is an abnormal detection state, which may be an interfered state or a failure state of the light sensing element of the single lamp controller of the first street lamp 12.

In order to avoid that the detection result of the single lamp controller does not match the actual environment state of the target area, and thus the single lamp controller is always in an abnormal control state such as a light-on state, a brightness percentage mismatch state, or a light-off state, the server 11 of this embodiment determines the target adjustment parameter of the single lamp controller of the first street lamp 12 based on the target environment state, where the target adjustment parameter may be a dimming parameter for determining a dimming compensation logic of the single lamp controller, and may include a first dimming parameter generated according to the detection state of the single lamp controller of one or more street lamps adjacent to the single lamp controller with the electrical abnormality, and a second dimming parameter determined by a sensor of the first street lamp 12, so that the control state of the single lamp controller may match the actual target environment state.

And the first street lamp 12 is connected with the server 11 and is used for adjusting the abnormal detection state of the first street lamp 12 to a normal detection state through the target adjustment parameter.

The first street light 12 of this embodiment communicates with the server 11 via wireless communication, which may be one or more of Wi-Fi (e.g., 802.11 protocol), high frequency transceiver, infrared IR, GSM + EDGE, Lo-Ra, or any other wireless communication protocol, or any combination thereof.

The first street lamp 12 obtains the target adjustment parameter sent by the server 11 through wireless communication, and may obtain the compensation control instruction carrying the target adjustment parameter sent by the server 11. After the single lamp controller of the first street lamp 12 obtains the target adjustment parameter, the single lamp controller 12 may adjust based on the target adjustment parameter, and may adjust the electrical state of the single lamp controller to be consistent with the electrical state of the single lamp controller lamp in the surrounding normal detection state, where the normal detection state is an undisturbed state or a normal working state of the photosensitive element of the single lamp controller of the first street lamp, thereby avoiding energy waste caused by too bright a lamp due to interference or failure of the street lamp, or failure of meeting an expected target in a road lighting environment due to too dark a lamp, and performing timely maintenance processing on the single lamp controller in the interfered or failed state, thereby improving the lighting efficiency of the street lamp.

It should be noted that, the first street lamp 12 in this embodiment may be any street lamp in a street lamp control system, and the number of the first street lamps may be one or multiple, and is not limited herein.

In this embodiment, the server 11 obtains the target adjustment parameter of the single lamp controller of the first street lamp 12, and the abnormal detection state of the first street lamp is adjusted to the normal detection state by the target adjustment parameter through connection between the first street lamp 12 and the server 11. That is to say, when the single lamp controller is in an abnormal detection state (a state of being interfered or failed), the parameters for adjusting the single lamp controller in the abnormal detection state are determined according to the surrounding environment state, so that the parameters are consistent with the normal state of the single lamp controller, the technical problem of low lighting efficiency caused by the fact that the street lamp control system is lack of self-adaptive judgment of the environment state is solved, and the technical effects of self-adaptive judgment of the environment state and improvement of the lighting efficiency of the street lamp control system are achieved.

The system of the embodiment further includes a collector, which is also a data collection module, configured to acquire and store the first detection state, and optionally, configured to acquire and store an illuminance value of the light source and an operation state of each light source that are required to be controlled by the single lamp controller of the first street lamp. Optionally, one collector of this embodiment may correspond to one area divided according to a preset logic, and the one area may include one or more single-lamp controllers of the street lamps.

Optionally, the data acquisition module of this embodiment comprises a signal processor, which may be a digital signal processor for processing digital signals in real time, the digital signals being converted from analog signals by the input/output circuitry of the single lamp controller. After the digital signal processing is complete, the digital signal may also be converted back to an analog signal.

Optionally, the single lamp controller of the first street lamp in this embodiment may establish a communication connection with the collector, and the collector may obtain the registration request sent by the single lamp controller of the first street lamp. Optionally, the registration request includes the geographical location information of the single lamp controller for the first street lamp, the device code corresponding to the single lamp controller and/or the network address, for example, which needs to be acquired, and then the collector further uploads the registration request to one or more servers, which create a registration list for the single lamp controller for the first street lamp. The area position of the single lamp controller of the first street lamp is obtained through the equipment code of the single lamp controller, and then the illumination value and the light source running state detected by the single lamp controller and one or more other single lamp controllers around the single lamp controller are inquired through the registered position information. For example, after the power of each street lamp is turned on, the single lamp controller may feed back the operation status after several commissioning commands issued by the server and transmit characteristic parameters of the light source controlled by each single lamp controller, which may include power, dimming range (such as color temperature, color, etc.), and/or other sensor parameters. When the server generates the above registration information, a data list may be formed in the storage device, where the data list includes all possible characteristic parameters obtained through the registration, and for some light sources of the street lamps, some characteristic parameters are null values. Thus, when some light sources which can be adjusted to light need to be replaced, some newly added characteristic parameters can be correspondingly filled. For example, if there are unregistered single lamp controllers in some areas, the data acquisition module is configured to establish communication with the single lamp controller to obtain specific parameters thereof, and create a registration list for the single lamp controller through the local server.

After the registration is completed, the data acquisition module of this embodiment may be further configured to calculate an actual illuminance value of the light source and an operating state of the light source at a position in the area where the single-lamp controller of the first street lamp is located. If the illuminance value of the single lamp controller is seriously inconsistent with the actual illuminance value, the server issues the actual lamp state and closes the self-adaptive function to the single lamp controller, so that the lamp state of the single lamp controller is consistent with the lamp states of other surrounding single lamp controllers, the single lamp controller is closed to adjust the lamp state through the change of the illuminance sensor, and then the server marks the single lamp controller as an interfered or fault state temporarily. If the illuminance value detected by the single lamp controller returns to normal, the server issues an opening adaptive adjustment function, so that the single lamp controller returns to automatically change through the change of the illuminance value detected by the photosensitive element of the single lamp controller, and removes the operation state of the single lamp controller which is temporarily marked as interfered or failed.

The single lamp controllers respectively built in the multiple street lamps of the embodiment can form an operation network through the collectors adjacent to each other, the operation network can be defined as forming an illumination area, and the illumination area can also be defined by the maximum range which can be irradiated by the street lamps. Optionally, the plurality of data acquisition modules establish communication connection with a local server, so as to realize transmission of acquired data and reception of a data acquisition request.

Optionally, the data acquisition module of this embodiment may further obtain coordinates of the geographic location where the target area is located, so as to obtain the weather data of the geographic area from a local or server.

Optionally, the collector is disposed in the server.

In this embodiment, one or more collectors may be disposed in the server, that is, the server may perform unified management on one or more collection servers.

In this embodiment, the plurality of second street lamps may be located in the target area through the first street lamp, and the server determines the first target environmental state of the target area through the detection state of the single lamp controller of the plurality of second street lamps. The second street lamps and the first street lamp of the embodiment may be installed in the target area in a preset fixed manner, or may be installed in a continuous manner, for example, the first street lamp and the second street lamps are installed at equal intervals in a road guiding manner set by an electronic geo-fence, and the structures and functions of the second street lamps may be the same as those of the first street lamp.

The server obtains a second detection state of the single lamp controller of each second street lamp to obtain a plurality of second detection states, where the plurality of second detection states may be the same detection state, for example, the illuminance indicated by the plurality of second detection states is the same, and optionally, the difference between the illuminance indicated by the plurality of second detection states may be considered as the same second detection states as long as it is within a certain threshold range, and if the first detection state of the single lamp controller of the first street lamp is different from the second detection states of the single lamp controllers of the plurality of second street lamps, the first target environment state of the target area is determined through the plurality of second detection states, that is, if the first detection state of the single lamp controller of the first street lamp is different from the second detection states of the single lamp controllers of most other surrounding street lamps, the detection state of the single lamp controller of the first street lamp is an abnormal detection state, the first target environment state of the target area may be determined by a plurality of second detection states, for example, the same illumination value indicated by the plurality of second detection states is determined as the illumination value of the current target area. The target adjustment parameter determined by the embodiment based on the first target environmental state may be a first dimming parameter for adjusting a single lamp controller of the first street lamp.

In this embodiment, the body support housing of the first street light mounts a number of light sources and a sensing module. The sensing module may include a photosensitive element for sensing illuminance, a control circuit thereof, and a sensor with a combined function. The sensing module can be installed on a main body bracket shell of the first street lamp, and the main body bracket shell can also be provided with a plurality of light sources.

The light sensing element of this embodiment is used for sensing illuminance values, is a single sensing unit suitable for ambient light illuminance sensing and scene atmosphere sensing, and the control circuit may be enclosed in an inner cavity of the main body support housing or a suitable load-bearing space, for example, the main body support housing may include a waterproof sealing structure on a top wall or a top side wall of the top edge of the first street lamp for mounting the light sensing element and the control circuit therearound. Sometimes for efficient collection of ambient light, the light sensing element may be arranged in a cover plate or an extension of a cover plate inclined at a predetermined angle with respect to the top edge, or the structure may be fixed in a substrate formed by such cover plate and/or extension to form a sealed sensor module component. The integrated circuit of the photosensitive element is a single chip or a chip set which is suitable for processing and/or filtering the sensed photoelectric signal, and may be an ASIC, and the photosensitive element controls the light source of the first lamp to be turned on or off according to the sensed light illumination value, for example, the photosensitive element does not output a photocurrent and turns on the light source, and the photosensitive element outputs a photocurrent and turns off the light source; alternatively, in case that multiple electrical functions (e.g. combination of ambient light sensing and ultrasonic sensing) need to be used, which may be performed and output by a single sensing unit, the sensing signal is processed by a single control circuit, thereby avoiding the need for a single sensing module to separately trigger the single light controller when performing sensing, so that a certain function of the single light controller may be triggered by combining sensing. Optionally, the first street light is powered by a photo-electrically displaced photo-sensitive element (e.g. a photovoltaic element) in order to provide a limited power supply to the light source of the first street light at night.

The sensor of the embodiment is connected with the photosensitive element, and is configured to control the photosensitive element according to a detected second target environment state of the target area, the embodiment may detect the second target environment state of the target area through the sensor, the target adjustment parameter determined based on the second target environment state may be a second dimming parameter for adjusting the single lamp controller of the first street lamp, and the second dimming parameter may determine a logic for adjusting the single lamp controller of the first street lamp together with the first dimming parameter.

The sensor of the embodiment comprises an acoustic port, and the main body support shell of the first street lamp can also extend from the top wall to the position of a lamp post of the main body support of the street lamp, and is provided with the acoustic port with a proper size. Optionally, the acoustic port of this embodiment is configured to allow ambient sound from around the enclosure to be conveyed to the acoustic sensor within the enclosure for sound pickup. Alternatively, the acoustic port of this embodiment may be used as an output port (e.g., a speaker) to output sound from the acoustic port to the road surface or the surrounding environment. Optionally, the acoustic port of this embodiment is disposed in the lamp post side housing of the first street lamp, and may also be mounted in the housing near the bottom side of the lamp post of the first street lamp. Alternatively, the acoustic port of this embodiment may have both components that output sound waves to the ambient environment and that receive sound waves, which allows sound waves (including ultrasonic waves) to be output outward through the acoustic port and reflected back to the acoustic port by obstacles.

In this embodiment, the acoustic port may be selected to detect obstacles that may be present near the location of the light sensing element using ultrasonic sensing elements. Optionally, the acoustic port of this embodiment further comprises a speaker with a display interface or a microphone device for collecting an ambient sound field, disposed on a side wall of the light pole of the first street light. In addition, the ultrasonic sensing element can also be used for signal acquisition of a meteorological sensor. In addition to the above-mentioned types of sensors, the target adjustment parameter may also be determined by a second target environment state determined by other types of sensors, where the other types of sensors may be a temperature and humidity sensing element, an optical sensing element (e.g., a camera), a pressure sensor, and the like, for example, when an image of an area near the first street lamp is monitored in real time by using the camera, whether to activate the light source of the first street lamp may be triggered by the brightness of the field of view to improve the photographing effect.

Optionally, the sensor of this embodiment further comprises a water immersion sensing element which may be mounted or otherwise integrally coupled to the underside of the body of the first light to allow it to sense the ground level of the target area. For example, the water immersion sensor may be disposed at a predetermined height from the ground or coupled to the sensor. Optionally, the water immersion sensor of this embodiment may also include a sensor element disposed in a bottom cavity formed by the ground support member of the pole of the first street light, and an integrated circuit disposed at a top edge of the body support of the first street light. Here, a hollow structure may be formed in the lamp post of the first street light, wherein the acoustic port and other forms of sensors like the sensing element for water level sensing applications may share the hollow structure, and the top surface and/or the side surfaces of the lamp post of the first street light may be provided with additional sensors, so that the hollow structure may be fully utilized. Alternatively, in order to facilitate the inspection and replacement of these sensors, the sensors and their control circuits may be installed in an electric box of the main body bracket of the first street lamp near the ground portion.

Alternatively, the hollow structure of this embodiment may be divided into a first chamber for mounting the control circuit and a second chamber for arranging other sensing modules with lower protection requirements. For example, the first chamber may be a chamber having a reference pressure, temperature, humidity, etc., which is optionally substantially highly sealed from the surrounding environment (or has only a small leak or vent). The second chamber may be a chamber that is open to the ambient environment, such as via an acoustic port, water immersion sensitive element, and in some embodiments may be electrically isolated or sealed from the first chamber.

The sensors of this embodiment also include weather sensors for detecting weather data for the target area, which may be systematically categorized weather data or may be obtained from a server. The embodiment determines a second target environmental state based on the meteorological data, by which the determined target adjustment parameter may act on an accurate control of the light source.

The sensor of this embodiment may further include a temperature and humidity sensing element for sensing a temperature and a humidity of the target area.

The sensor of this embodiment may further comprise an optical sensing element, which may be a camera, for detecting an image of the target area. For example, when the camera is used to monitor the image of the target area in real time, whether the light source is activated or not can be triggered by the brightness of the field of view to improve the shooting effect.

The sensor of this embodiment may further comprise a pressure sensor for detecting air pressure. The pressure sensor of an embodiment is used for responding to an input of air flow and/or pressure of air, such as, for example, ambient air flow into the hollow structure, a change in air pressure sensed by the pressure sensing element, and may also be used for triggering a change in current proportional to the air flow input in response to the air flow change, which in turn may be used for the control circuit to sense, for example, ambient wind. Sometimes, such sensing may also be based on pressure differentials or temperature changes resulting from hot and cold airflow collisions. For example, in some implementations, due to a large wind force, there may be branches or obstacles blocking the light sensing element, and the parameter sensed by the pressure sensor serves as a logic condition for suppressing triggering the light sensing element not to output a photocurrent due to the blocking to turn on the light source.

Optionally, the first street lamp of this embodiment further has a positioning module therein, and the positioning module is configured to transmit positioning data to the single-lamp controller, so as to transmit coordinates, which may reflect a geographic area where a target area is located, to the data acquisition module corresponding to the target area including the first street lamp, so as to obtain meteorological data of the geographic area from a local or remote server, and thereby determine the second target environmental state. Wherein the target adjustment parameter determined based on the second target environmental state may act on a precise control of the light source. Optionally, the embodiment may also perform data synchronization to the plurality of single lamp controllers in the other zone by the target adjustment parameter generated based on the second target environmental state of the target zone.

Alternatively, the substrate of this embodiment may include a surface structure for extracting light energy such that a variable capacitance is formed in the surface structure. Alternatively, the embodiment may change the position of the movable structure by a target adjustment parameter determined based on the second target environmental state. Optionally, an input in response to the air flow and/or pressure of the air, e.g. a change in air pressure sensed by the pressure sensing element when ambient air flows into the hollow structure of the first street lamp, or a change in air flow triggers a change in current proportional to the air flow input, which in turn may be used for the control circuit to sense an ambient condition, such as ambient wind. Alternatively, such sensing may be implemented based on a pressure difference or temperature change caused by hot and cold airflow collision, for example, due to a situation that a branch or an obstacle blocking the light sensing element may exist due to a large wind force, and a parameter sensed by the pressure sensing element is used as a logic condition for suppressing triggering the light sensing element not to output a photocurrent and turn on the light source due to blocking.

Optionally, the substrate provided with the photosensitive element on the first street lamp of this embodiment may be used to detect whether to transmit the sensing signal to the control circuit based on the change of the ambient light illuminance. In order to collect electric power, the base plate may be disposed as a movable structure with respect to the top of the main body support, for example, the movable structure may be electrically and mechanically connected to the main body support at an upper position or a lower position thereof by a supporting and rotating member, and the base plate of the first street lamp may be directed toward an irradiation angle of sunlight as much as possible, so that when used as a photoelectric replacement function, light energy collection efficiency of the photosensitive element of the single lamp controller of the first street lamp may be improved.

Optionally, the first street lamp of this embodiment may further include a control circuit for processing the photocurrent signal or the plurality of different levels of voltage signals output by the light sensing element, for example, an application specific control circuit (ASIC) chip fixedly mounted in a housing, the ASIC chip may be mounted to a bottom side of the housing of the first street lamp and electrically connected to the light sensing element, the ASIC chip may be used for signal conditioning and/or processing the ambient light signal and the pressure induced electrical signal output by the light sensing element for sensing whether the single lamp controller of the first street lamp should be normally triggered to output the electrical control command.

The light sensing elements of this embodiment may be further configured to respond to and identify lower and/or higher magnitudes of change associated with ambient light changes in the target area. For example, the light sensing elements may have variations in illumination in response to lux greater than, for example, 200 up to 700 or more, or the light sensing elements may measure variations outside of the illumination range to which they respond at night. The photosensitive element of the first street lamp and the photosensitive element of the other second street lamp can be different, the photosensitivity of the photosensitive element shielded by the obstacle is higher than that of the photosensitive element not shielded by the obstacle, for example, the illumination level of the ambient light on the photosensitive element shielded by the tree for a long time is higher than that of the photosensitive element directly exposed to sunlight, so that the photosensitive element shielded by the tree for a long time has higher photosensitivity, and the photosensitive element sensitively responds to ambient light input (such as low illumination), but does not respond to light input with stronger illumination, for example, does not respond to the flicker change of the lamp decoration. Here, the light sensing elements of different street lamps may act in response to different predetermined illuminance changes, and thus, corresponding current/voltage signals output by different portions may be rectified and filtered by an ASIC chip or processed by other circuits, thereby outputting or measuring different illuminance level detection electrical signals for different single lamp controllers.

Optionally, in this embodiment, the light sensing element of the first light outputs the sensing signal to the ASIC chip via a power conductor or suitable power bus form, and the light sensing element outputs the sensing signal to another ASIC chip via another power conductor, and each of these sensing signals may then be filtered by the ASIC chip to provide a measurement output of ambient light at a given time. Alternatively, sensing signals corresponding to the entire illumination range may be output to the ASIC chip at regular times (e.g., daily), and the ASIC chip may process these sensing signals to determine ambient light (e.g., low-illumination environment) and simultaneous acoustic signal pickup (e.g., ultrasonic feedback signal).

Alternatively, this embodiment may obtain the illumination reference from the light sensing elements of other street lamps in a locally uniform lighting environment without the need for remote acquisition through a local server. Alternatively, the photosensitive element of this embodiment may be included in a piezoelectric trigger that detects thermal energy radiation of ambient light.

The substrate requiring the photosensitive element is mechanically moved due to the change of the ambient light for detecting or measuring the thermal energy collection efficiency of the ambient light. Alternatively, the light sensing element of the first street lamp may be moved according to the orientation of the road crossbar network.

This embodiment may be used to detect whether to transmit a sensing signal to the control circuit based on a change in ambient light level. In order to collect electric power, the base plate may be disposed as a movable structure with respect to the top of the main body support, for example, the movable structure may be electrically and mechanically connected to the main body support at an upper position or a lower position thereof by a supporting and rotating member, and the base plate of the first street lamp may be directed toward an irradiation angle of sunlight as much as possible, so that when used as a photoelectric replacement function, light energy collection efficiency of the photosensitive element of the single lamp controller of the first street lamp may be improved.

The first street lamp of the embodiment further comprises a positioning device, wherein the positioning device is used for transmitting the positioning data to the single-lamp controller, so that the coordinates which can reflect the geographical area where the target area is located are transmitted to the data acquisition module corresponding to the target area containing the first street lamp, and the meteorological data of the geographical area can be acquired from a local or remote server, so that the second target environment state can be determined. Wherein the target adjustment parameter determined based on the second target environmental state may act on a precise control of the light source. Optionally, the embodiment may also perform data synchronization to the plurality of single lamp controllers in the other zone by the target adjustment parameter generated based on the second target environmental state of the target zone.

In this embodiment, when the second street lamp is a street lamp in the target area and adjacent to the first street lamp, and the second street lamp and the first street lamp may be both in a locally uniform illumination environment, the second detection state of the single-lamp controller of the second street lamp may be used as a reference, and the second detection state may be determined as a third target environment state, for example, the illuminance value of the second street lamp is determined as the illuminance value corresponding to the target environment state, and does not need to be remotely obtained through a server.

In this embodiment, when the server determines that the first detection state is the abnormal detection state, the server may further send a prompt message through the message prompt. If the first detection state of the single lamp controller of the first street lamp is recovered from the abnormal detection state to the normal detection state and the abnormal detection state occurs quickly, namely, when the single lamp controller frequently jumps back and forth between the normal detection state and the abnormal detection state, the server sends prompt information, the prompt information can be used for prompting a manager that the single lamp controller frequently occurs the abnormal detection state and can also prompt reasons and suggestions of the abnormal detection state, for example, the illuminance sensor is possibly frequently irradiated by a headlamp of an automobile, and a maintainer is advised to replace the installation position of the illuminance sensor.

Optionally, in this embodiment, if the single lamp controller of the first street lamp is in the normal detection state at night and in the abnormal detection state during the day, the server sends a prompt message to prompt the reason and the suggestion that the abnormal detection state occurs, for example, to prompt the manager that the single lamp controller is blocked by a blocking object and to recommend the maintenance staff to eliminate the interference source.

Optionally, if the single lamp controller of the first street lamp is in an abnormal detection state for more than one day, the server may send a prompt message, which may be used to prompt a manager that the illuminance sensor of the single lamp controller of the first street lamp is faulty, and advise a maintenance worker to replace the illuminance sensor.

Optionally, the system of this embodiment further comprises a storage device, which may include local and remote storage means, and the local storage means may be, for example, a hard disk drive, a flash memory, a cache, a ROM, and/or a RAM. Additionally, the storage may be a local and/or remote storage device. For example, the storage device may include an integrated storage medium, a removable storage medium, and the like. The remote storage means may be an open storage space on another remote server, a cloud server, a wireless storage medium, or any combination thereof. Additionally, the storage device may be used to store weather data (e.g., systematically categorized weather data), registered user data for each or some of the street lamps, and any other relevant data.

In this embodiment, the first street light further comprises a power supply module, which can be used to supply power to the light source and other components (e.g., sensor, single light controller) of the first street light. Optionally, the power supply module of this embodiment may be coupled to an electrical power grid, such as a 220VAC power line. In some embodiments, the power module may include one or more batteries for powering network routing devices built into the pole of the street light and/or other types of external devices associated with the charging facility. As another example, the power module may also be configured to generate power from using a solar photovoltaic substrate.

Alternatively, the power supply module of this embodiment may be divided into two paths: the 12V power level of one AC/DC path and the 3.3V power level of the other DC/DC path. The 12V output end can be used as the 3.3V input end, one end of the AC/DC input end is connected with the data acquisition module, and the other end is connected with the neutral wire N of the power grid, while the DC/DC output end is connected with a control circuit comprising an ASIC chip to supply power to the control circuit.

Optionally, the control circuit of this embodiment further includes a switch relay control module, one end of the relay switch functional pin is connected to the data acquisition module, the other end of the relay switch functional pin is connected to the neutral line N of the power grid, and the control terminal is connected to the ASIC chip. In some embodiments, the control circuit may further include a Dimming module for modulating the brightness and/or color temperature, color, etc. of the light source, one end of the Dimming module is coupled to the Dimming control lead of the first street lamp, for example, one end of the Dimming module is coupled to Dimming +/Dimming-of the single lamp controller, and the other end of the Dimming module is coupled to the ASIC chip.

Additionally, the control circuit of this embodiment is further coupled to a wireless communication module operable to initiate a wireless communication request, connect to a communication network established by the network routing device, and/or transmit communication data to one or more local servers or data switching devices within the communication network. For example, the communication circuit may support one or more of Wi-Fi (e.g., 802.11 protocol), high frequency transceiver, infrared IR, GSM + EDGE, Lo-Ra, or any other communication protocol and/or any combination thereof. The wireless communication module is in communication connection with the ASIC chip and is used for transmitting dimming data through UART interface communication.

According to the embodiment, the target adjustment parameter of the single lamp controller of the first street lamp is acquired through the server, the first street lamp is connected with the server, and the abnormal detection state of the first street lamp is adjusted to the normal detection state through the target adjustment parameter. That is to say, when the single lamp controller is in an abnormal detection state (a state of being interfered or failed), the parameters for adjusting the single lamp controller in the abnormal detection state are determined according to the surrounding environment state, so that the parameters are consistent with the normal state of the single lamp controller, the technical problem of low lighting efficiency caused by the fact that the street lamp control system is lack of self-adaptive judgment of the environment state is solved, and the technical effects of self-adaptive judgment of the environment state and improvement of the lighting efficiency of the street lamp control system are achieved.

Fig. 4 is a schematic view of a street lamp according to an embodiment of the present invention. As shown in fig. 4, includes: light source 101, light sensing element 102, single lamp controller SN1, cover plate 107, cover plate extension 1071, acoustic port 104, camera 108, temperature and humidity sensing element 109, speaker 1041, lamp pole 106, electrical cabinet 110.

The light sensing element 102 and control circuitry may be housed within the body mount housing cavity or suitable load bearing space. The main body bracket housing may include a water-tight seal on the top wall or top side wall of the street light top rim for mounting the light sensing element 102 and control circuitry thereabout. Sometimes for efficient collection of ambient light, the light sensing element 102 may be arranged in a cover plate 107 or an extension 1071 of the cover plate inclined at a predetermined angle relative to the top edge, or the structure may be fixed in a substrate formed by such cover plate and/or extension to form a sealed sensor module component.

Fig. 2, 3 and 4 are further described below.

In this embodiment, a plurality of street lamps and their light sources, and a single lamp controller coupled to the light sources are installed in different areas. This embodiment installs multiple street lights and their light sources in different areas, as shown in fig. 2, and a single light controller coupled to the light sources.

In this embodiment, after the power supply module supplies power to the electronic circuits such as the light source, the single lamp controller, and the like, the single lamp controller of each street lamp may send a registration request to the data acquisition module. In one example, the registration request includes the geographical location information of the single lamp controller, the device code corresponding to the single lamp controller and/or the network address, for example, which the single lamp controller needs to acquire, and then the data collection module further uploads the registration request to one or more local servers to form a registration list.

The local server may group a plurality of such single lamp controllers into such an area (such as determined by geo-fencing) according to a predetermined logic by geo-location information, thus forming a single lamp control system network. Sometimes, the local server may be configured to use the device-coded indication of each single light controller as an identification of the geolocation information.

The local server of the embodiment can acquire and store the illumination values of the light sources required to be controlled by the single-lamp controller and the operating states of the light sources through the plurality of data acquisition modules.

In this embodiment, the device code of each single-lamp controller obtains the location of the area where the single-lamp controller is located, and then, through the registered location information, queries the illuminance value and the light source operation state detected by the single-lamp controller and other one or more single-lamp controllers around the single-lamp controller through such registration. For example, after the power of each street lamp is turned on, the single lamp controller may feed back the operation status after several commissioning commands issued by the local server and transmit characteristic parameters for the light source controlled by each single lamp controller, where the characteristic parameters may include power, dimming range (such as color temperature, color, etc.), and/or other sensor parameters. Typically, when the local server forms the registration, a data list may be formed in the storage device, where the data list includes all possible characteristic parameter bits obtained by the registration, and for some street lamp light sources, some characteristic parameters are null values. Thus, when some light sources which can be adjusted to light need to be replaced, some newly added characteristic parameters can be correspondingly filled. For example, in some areas there are still unregistered single lamp controllers, in which case the data acquisition module is configured to establish communication with the single lamp controller to obtain its specific parameters and create a registration list for the single lamp controller via the local server.

After the registration is completed, the data acquisition module is configured to calculate the actual illumination value of the light source and the operating state of the light source at the position in the area where the single lamp controller is located. When the illuminance value of the single lamp controller is seriously inconsistent with the actual illuminance value, the local server issues the actual lamp state and closes the self-adaptive function to the single lamp controller, so that the lamp state of the single lamp controller is consistent with the lamp states of other surrounding single lamp controllers, the single lamp controller is closed to adjust the lamp state through the change of the illuminance sensor, and then the local server temporarily marks the single lamp controller as an interfered or fault state.

If the illuminance value detected by the single lamp controller returns to normal, the local server issues to turn on the adaptive adjustment function, so that the single lamp controller returns to the operation state of being temporarily marked as interfered or failed by changing the illuminance value detected by the photosensitive element of the single lamp controller and automatically changing the illuminance value.

In this embodiment, the storage means may include local and remote storage means, and the storage means provided locally may be, for example, a hard disk drive, flash memory, cache, ROM and/or RAM. Additionally, the storage may be a local and/or remote storage device. For example, the storage device may include an integrated storage medium, a removable storage medium, and the like. The remote storage means may be an open storage space on another remote server, a cloud server, a wireless storage medium, or any combination thereof. Furthermore, the storage device may store meteorological data, such as, for example, systematically categorized meteorological data, registered user data for each or some street lamps, and any other relevant data.

The data acquisition module of this embodiment may comprise a signal processor, which may be, for example, a digital signal processor for processing digital signals in real time, the digital signals being converted from analog signals by the input/output circuitry of the single lamp controller. The digital signal may also be converted back to an analog signal after processing of the digital signal is complete.

As an alternative example, the operating status of several street lamps located in the first area is collected to identify the operating status of the single lamp controller in which an electrical anomaly exists.

Fig. 2 depicts a network topology in the form of a network of nodes. The area may be defined by end nodes such as geofences, signal ranges or wiring that the wireless/wired network can cover. In fig. 3, a first area RGN1 has a plurality of street lamps installed in a predetermined fixed (or continuous) manner, such as street lamps installed equidistantly according to a road guidance manner set by an electronic geo-fence, however, the interference sources in these areas may occur randomly. The individual lamp controllers SN1, SN2, SN3 and SN4 built in a plurality of street lamps can form an operation network by the data acquisition modules adjacent to each other, and the operation network can be defined as a lighting area (or defined by the maximum range that the street lamps can irradiate). The plurality of data acquisition modules are in communication connection with a local server, so that the transmission of the acquired data and the reception of the data acquisition request are realized. Optionally, the data acquisition module is contained in a local server. The local server is connected with the remote server and can be used for realizing remote storage.

In this embodiment, when one or more single lamp controllers SN1 are interfered by an external source, the illuminance value of the street lamp light source detected by the single lamp controller SN1 will change greatly, and the operating state of the single lamp controller will also change due to the adaptive adjustment function of the single lamp controller, and then the single lamp controller reports the current illuminance value, the changed lamp state, and the SN number to the local server through wireless transmission.

The first dimming parameter is generated according to the operation state of the single lamp controller of one or more street lamps adjacent to the single lamp controller with the electrical abnormity. The first dimming parameter is combined with a second dimming parameter to determine dimming compensation logic.

In fig. 2, a street light 100 has a main body support housing for mounting several light sources 101 and sensing modules. The sensing module includes a light sensing element 102 for sensing illuminance and a control circuit thereof (the light sensing element 102 and the control circuit may be packaged in an inner cavity of a main body bracket shell or a suitable bearing space), and a sensor element with combined functions, such as a water immersion sensor, an acoustic sensor, and the like. The light sensing element 102 is a single sensing unit adapted for ambient light illumination sensing and scene ambience sensing, and the integrated electrical circuit, such as a dedicated control circuit ASIC, is a single chip or chip set adapted for processing and/or filtering the sensed photo-electric signal. Sometimes, it is desirable to use multiple electrical functions (such as ambient light sensing and ultrasonic sensing in combination) that can be performed and output by a single sensing element, with the sensing signal being processed by a single control circuit, thereby eliminating the triggering of a single sensing module on a single light controller alone when performing sensing, but rather triggering some function of the single light controller by combining sensing. Sometimes, the street light 100 has a light sensitive element (such as a photovoltaic element) for photoelectric displacement to collect electrical energy in order to provide a limited power supply to the light source 101 at night.

Additionally, the body frame enclosure may also open an acoustic port 104 of suitable size from the top wall to the location of the light pole of the street light body frame, and in some embodiments, the acoustic port 104 may be configured to allow ambient sound from around the enclosure to be transmitted to an acoustic sensor within the enclosure for sound pickup. In other embodiments, the acoustic port 104 may function as an output port (e.g., as a speaker) to output sound from the acoustic port 104 to the road surface or the surrounding environment.

In fig. 2, such an acoustic port 104 is shown simplified within a pole side housing of a street light. In other embodiments, the acoustic port 104 may also be mounted in the housing near the underside of the light pole. In further embodiments, the acoustic port 104 may have both components to output sound waves to the ambient environment and to receive sound waves, which allows sound waves (including ultrasonic waves) to be output outward through the acoustic port 104 and reflected back to the receiving components within the acoustic port 104, such as by an obstruction, to determine and gauge the obstruction, and may trigger the light sensing element 102 through such a gauge.

Additionally, the water immersion sensing element 103 may be mounted or otherwise integrally coupled to the underside of the street light body to allow for ground level sensing. For example, the water immersion sensor 103 may be disposed at a predetermined height from the ground or coupled to more than one sensor module. In some embodiments, the water immersion sensing element 103 may also include a sensing element disposed in a bottom cavity formed by the ground support member of the light pole and an integrated circuit disposed at the top edge of the body bracket. Here, a hollow structure may be formed in the light pole, wherein the hollow structure may be shared by the acoustic port 104 and other forms of sensors like sensing elements for water level sensing applications, and the top and/or sides of the light pole may be arranged with additional sensing modules to make full use of such hollow structure. Sometimes, in order to facilitate the inspection and replacement of the sensors, the sensing module and its control circuit are usually installed in the electrical box 110 of the street lamp main body bracket near the ground portion.

In other embodiments, the hollow structure may be divided into a first chamber for mounting the control circuitry and a second chamber for arranging other sensing modules with less demanding protection requirements. For example, the first chamber may be a chamber having a reference pressure, temperature, humidity, etc., which in some embodiments is substantially highly sealed from the surrounding environment (or has only a small leak or vent). The second chamber may act as a chamber open to the ambient environment, such as via the acoustic port 104, the water immersion sensitive element 103, and may be electrically isolated or sealed from the first chamber in some embodiments.

Alternatively, the substrate 105 having the light sensing element 102 may be used to detect whether to transmit a sensing signal to the control circuit based on a change in ambient light illuminance. To collect power, the base plate may sometimes be arranged in a movable structure relative to the top of the main body support. For example, the movable structure is electromechanically connected at an upper or lower position to the body support by a support and rotation member. For example, in the application scenario shown in fig. 2, the substrate 205 of the street lamp 200 faces the irradiation angle of the sunlight as much as possible, while the substrate 105 of each street lamp shown in fig. 2 is biased at different angles. In this way, when the photoelectric conversion function is used, the light energy collection efficiency of the light-receiving element 102 is improved.

Changes in the sensed parameter as, for example, changes in the weather environment, may be corrected by other forms of data. The acoustic port 104 is sometimes selected for use with an ultrasonic sensing element to detect what may be near the location of the photosensitive element 102 to effectively detect obstructions. Sometimes, the acoustic port 104 further includes a speaker 1041 with a display interface disposed on a sidewall of the light pole 106 or a microphone device for capturing an ambient sound field. In addition, the ultrasonic sensing element can also be used for signal acquisition of a meteorological sensor. In addition to these sensing elements, the second dimming parameter can also be sensed by other types of sensors (such as the temperature and humidity sensing element 109 shown in fig. 4, an optical sensing element (such as the camera 108), a pressure sensor, and the like). For example, when the camera 108 is used to monitor the image of the area near the street lamp 100 in real time, whether to activate the light source 101 may be triggered by the brightness of the field of view to improve the photographing effect.

In this embodiment, the street lamp 100 further has a positioning module therein, and the positioning module is configured to transmit positioning data to the single-lamp controller, so as to transmit coordinates reflecting the geographic region of the region RGN1 to the data acquisition module corresponding to the region RGN1 containing the street lamp 100 shown in fig. 3, so as to obtain weather data of the geographic region from a local or remote server. The second dimming parameter, which is characteristic of the meteorological data, acts on the precise control of the light source 101. In another embodiment, possibly with the second zone RGN2 formed by the registration operation described above, the local server is configured to data synchronize the second dimming parameters generated from the first zone RGN1 to the single lamp controllers within the second zone RGN 2.

The substrate 105 may include a surface structure for extracting light energy such that a variable capacitance is formed in the surface structure. In some implementations, the position of the movable structure can be changed by a second dimming parameter. In other embodiments, an input responsive to the airflow and/or pressure of air (such as a change in air pressure sensed by a pressure sensing element as ambient airflow flows into the hollow structure) or a change in airflow triggers a change in current proportional to the airflow input which can then be used by the control circuitry to sense, for example, ambient wind. Sometimes, such sensing may also be based on pressure differentials or temperature changes resulting from hot and cold airflow collisions. For example, in some implementations, due to a large wind force, there may be branches or obstacles blocking the light sensing element 102, and the parameter sensed by the pressure sensing element serves as a logic condition for suppressing triggering the light sensing element 102 not to output a photocurrent due to the blocking and turning on the light source 101.

In the above-listed embodiments, the street lamp 100 may further include a control circuit for processing the photocurrent signal or the plurality of different level voltage signals output by the light sensing element 102, such as a dedicated control circuit (ASIC) chip fixedly mounted in the housing. The ASIC chip may be mounted to the bottom side 108 of the housing 102 and electrically connected to the photosensitive element 102 by wires. As previously described, the ASIC chip may be used to signal condition and/or process the ambient light signal and the pressure induced electrical signal output by the light sensing element 102 for sensing whether the electrical action command output by the single lamp controller of the street lamp 100 should be properly triggered.

In another embodiment, the light sensing element 102 for sensing ambient light may be further configured to respond to and identify a lower magnitude of change and/or a higher magnitude of change associated with ambient light changes. For example, the light sensing element 102 may have an illuminance variation in response to a lux greater than, for example, 200 up to 700 or more, or may be evaluated for changes outside of the range of illuminances to which the light sensing element 102 is responsive at night. The light sensing element 102 may be considered to be less sensitive than the light sensing element 202. For example, ambient light can illuminate the photosensitive element 202 that is shielded from the trees for a longer period of time at a higher illumination level than the photosensitive element 102 that is directly exposed to sunlight, and thus the photosensitive element 202 has a higher photosensitivity and responds sensitively to ambient light input (e.g., low illumination), but does not respond to light input with a higher illumination (e.g., a change in blinking of a light fixture). Here, the light-sensing element 102 and the light-sensing element 202 operate in response to different predetermined illuminance changes. The corresponding current/voltage signals output by the different sections may thus be rectified and filtered by the ASIC chip or processed by other circuitry to output or measure different illuminance level detection electrical signals for different single lamp controllers.

In one exemplary embodiment, the light sensing element 102 outputs the sensing signal to an ASIC chip via a power conductor or suitable power bus form, and the light sensing element 202 outputs the sensing signal to another ASIC chip via another power conductor. Each of these sense signals may then be filtered by an ASIC chip to provide a measured output of ambient light at a given time. Further, in other embodiments, sensing signals corresponding to the entire illumination range may be output to the ASIC chip at regular times (such as daily), and the ASIC chip may process these sensing signals to determine ambient light (such as a low-illumination environment) and simultaneous acoustic signal pickup (such as an ultrasonic feedback signal).

In addition, in a locally uniform lighting environment, the light-sensing element 202 may obtain the illumination reference from the light-sensing element 102 without having to obtain it remotely through a local server. In some embodiments, the light-sensing element 202 may comprise a piezoelectric trigger for detecting thermal energy radiation of ambient light as previously described. Further, in some embodiments, the substrate of the photosensitive element 202 needs to be mechanically moved due to the change of the ambient light, so as to detect or measure the thermal energy collection efficiency of the ambient light. Typically, the photosensitive element 204 for ambient light detection may be moved according to the orientation of the road crossbar network.

In some embodiments, the street light 100 also has a power supply module operable to supply power to the light source 101 and other components of the street light 100 (such as the sensing elements, single light controller described above). In some embodiments, the power supply module may be coupled to a power grid, such as a 220VAC power line. In some embodiments, the power module may include one or more batteries for powering network routing devices built into the pole of the street light and/or other types of external devices associated with the charging facility. As another example, the power module may also be configured to generate power from using a solar photovoltaic substrate.

The single-chip microcomputer control module is further connected with the data acquisition module through the switch relay control module and is connected with the LED street lamp through the dimming module. The 12V output end can be used as a 3.3V input end, one end of the AC/DC input end is connected with the data acquisition module, the other end of the AC/DC input end is connected with the power grid zero line N, and the DC/DC output end is connected with a control circuit comprising an ASIC chip and supplies power to the control circuit.

Fig. 6 is a schematic diagram of another control circuit according to an embodiment of the present invention. As shown in fig. 6, the power supply module of the single lamp controller of the street lamp of this embodiment supplies power to the ASIC chip through the L1(LIN) and L0(LOUT) pins of the data acquisition module, the ASIC chip operates, and the ASIC chip reads data acquired by the data acquisition module through the UART1 pin; the ASIC chip collects the current illumination value through an ADC sampling pin, adjusts the illumination of the light source 101 according to the illumination value, and sends data such as the illumination value, the running state and the like of the light source to the wireless communication module through a UART2 pin so as to wirelessly transmit the data to the local server. For example, the local server may display status data for each single lamp controller on the operator interface.

Optionally, one end of a relay switch function pin of the switch relay control module may be connected to the data acquisition module, the other end of the relay switch function pin is connected to the neutral line N of the power grid, and the control end of the relay switch function pin is connected to the ASIC chip. In some embodiments, the control circuit further comprises a Dimming module for modulating the brightness and/or color temperature, color, etc. of the light source 101, one end of the Dimming module is coupled to a Dimming control lead of the street lamp 100, such as Dimming +/Dimming-of the single lamp controller SN1, and the other end is coupled to the ASIC chip.

Additionally, the control circuit is coupled to a wireless communication module operable to initiate a wireless communication request, connect to a communication network established by the network routing device, and/or transmit communication data to one or more local servers or data switching devices within the communication network. For example, the communication circuit may support one or more of Wi-Fi (e.g., 802.11 protocol), high frequency transceiver, infrared IR, GSM + EDGE, Lo-Ra, or any other communication protocol and/or any combination thereof. The wireless communication module of this embodiment may be communicatively coupled to the ASIC chip, and communicate and transmit the dimming data through the UART interface.

Step S804, sending a compensation control command to a plurality of street lamps located in the first area according to the dimming compensation logic.

This embodiment may adjust the light source status of the disturbed or malfunctioning single lamp controller to be consistent with the electrical status of the single lamp controller lamps in the ambient normal operating state by calculating the actual ambient light illuminance value around the disturbed or malfunctioning single lamp controller.

Further, the interference source of the interfered or failed single lamp controller is calculated and analyzed through the embodiments, so that the maintenance personnel can provide maintenance service in time.

When the illuminance value detected by other surrounding single lamp controllers adjacent to the single lamp controller changes with the state of the street lamp, the local server sends a state command for controlling the single lamp controller, so that the state of the single lamp controller is always consistent with the running states of the other surrounding single lamp controllers. When the illuminance value detected by the single lamp controller changes again, the single lamp controller reports the current illuminance value to the local server, and the local server calculates the actual normal illuminance value according to the running states of other single lamp controllers around the single lamp controller and compares the two illuminance values to judge the compensation output.

In other embodiments, if the illuminance value detected by the single lamp controller returns to normal and is disturbed or failed soon, that is, the single lamp controller frequently jumps back and forth between the normal state and the disturbed or failed state, the local server prompts a manager that the single lamp controller is frequently disturbed by the outside world, possibly due to frequent irradiation of the illuminance sensor by a headlight of the automobile, and recommends a maintenance worker to replace the installation position of the illuminance sensor.

Optionally, if the single-lamp controller works in a normal range at night and is in an interfered or fault state in the daytime, the local server prompts a manager that the single-lamp controller is shielded by a shielding object, and recommends a maintenance person to eliminate an interference source.

If the single lamp controller is in an interfered or fault state for more than one day, the local server prompts a manager that the illuminance sensor of the single lamp controller is in a fault state, and recommends a maintainer to replace the illuminance sensor.

Fig. 7 is a schematic diagram of a local circuit of a dimming control module and a photosensitive element according to an embodiment of the present invention. As shown in fig. 7, the PWM signal is output through the ASIC chip, filtered to a periodically varying voltage of 0-3.3V by the filter circuit composed of resistors R6, R12, R8, and capacitor C12, amplified to a periodically varying voltage of 0-10V by the amplifier circuit composed of operational amplifier U1, resistors R3, R7, and R1, and then the output varying voltage may be connected to the Dimmg +, Dimmg-port. For example, the photoresistor R15 may be set, and the resistance value changes with the intensity of the illumination, so that the illumination signal is divided by R15, R16, and R14 and converted into a changed voltage signal, and then the changed voltage signal is input to the operational amplifier U1, and then the changed voltage signal is output to the ADC sampling pin of the ASIC chip through the resistors R13, R11, R9, the capacitor C11, the resistors R4, and the resistor R2.

The other components in fig. 7 of the embodiment to be described are only schematic and do not limit the scheme of the embodiment of the present invention.

When the illuminance sensor of the single lamp controller in the embodiment is interfered or fails, the state of the interfered single lamp controller is controlled by the illuminance values of the surrounding single lamp controllers, so that energy waste caused by too bright lamps or failure in maintaining the single lamp controller in time due to interference or failure of the single lamp controller caused by road lighting environment meeting an expected target due to too dark lamps is avoided.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
