Detailed Description
The street lamp control system according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic structural 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 of the present embodiment includes a vehicle sensing module 10, a light-on notification module 20, and a light-on control module 30. The vehicle sensing module 10 is used for sensing whether a vehicle is in the coming direction of the road corresponding to the street lamp; the light-on notification module 20 comprises a signal sending unit 21 and/or a signal receiving unit 22, wherein the signal sending unit 21 is used for sending a light-on signal when the vehicle sensing module senses the vehicle; the signal receiving unit 22 is used for receiving a light-on signal; the lighting control module 30 is configured to perform a lighting control operation on the street lamp in response to the received lighting signal.
According to an exemplary embodiment of the present invention, a street light control system is provided at each street light, for example, mounted on a lamp post of the street light. In the street lamp control system, the vehicle sensing module 10 senses whether a vehicle is in the coming direction of the road corresponding to the street lamp, and when the vehicle is sensed, the signal sending unit 21 sends a light-on signal, so that the signal receiving unit 22 corresponding to the current street lamp and the signal receiving units 22 corresponding to other street lamps on the current road can receive the light-on signal and send the light-on signal to the corresponding light-on control modules 30, so that the light-on control modules 30 corresponding to the street lamps perform light-on control operation, the street lamps are controlled to illuminate the current road, a good view field is provided for the vehicle, and safety driving of the vehicle is guaranteed. Moreover, the signal receiving unit 22 corresponding to the current street lamp may receive the turn-on signal sent by the signal sending unit 21 corresponding to the current street lamp, and may also receive the turn-on signals sent by the signal sending units 21 corresponding to other street lamps, thereby ensuring that the current street lamp can stably illuminate when a vehicle comes.
That is, the street lamp control system of the embodiment of the invention is used for controlling the street lamps on the road, so that the street lamp control system corresponding to each street lamp can control the current street lamp and a plurality of other street lamps to be turned on, and each street lamp can be controlled to be turned on by the street lamp control system corresponding to the current street lamp or the street lamp control systems corresponding to the other street lamps, even if the vehicle induction modules 10 or the signal sending units 21 corresponding to part of the street lamps are damaged, the normal turning-on of the street lamps can not be influenced, thereby ensuring that the street lamps can effectively provide stable illumination for the vehicles.
When the street lamp control system according to the embodiment of the present invention is disposed at a street lamp, as described above, the signal transmitting unit 21 and the signal receiving unit 22 may be disposed in the street lamp control system corresponding to each street lamp, or only the signal receiving unit 22 may be disposed in some of the street lamp control systems corresponding to the street lamps, without disposing the signal transmitting unit 21.
According to an alternative embodiment of the present invention, the vehicle sensing module 10 senses whether there is a vehicle in the coming direction of the road corresponding to the street lamp in real time, and sends a vehicle sensing signal to the light-on notification module when sensing the vehicle. For example, when the vehicle sensing module does not sense the vehicle, a vehicle sensing signal car _ arive (0) is transmitted to the light-on notification module; when the vehicle sensing module senses the vehicle, the vehicle sensing signal car _ arive (0) is converted into car _ arive (1), and the vehicle sensing signal car _ arive (1) is transmitted to the light-on notification module. In addition, the vehicle sensing module may reset the vehicle sensing signal car _ arive (1) to car _ arive (0) after a set time period (e.g., 1s), and continue to sense the vehicle.
In practice, the vehicle sensing module 10 may include one or more of a thermal sensor, a motion sensor, an optical sensor, a radar transceiver, or a self-initiated notifier. For example, the vehicle sensing module 10 includes a radar transceiver, and transmits a radar signal to a vehicle coming direction corresponding to the current street lamp, and determines that a vehicle is sensed when a returned radar signal is received. Of course, the vehicle sensing module is not limited to be composed of the aforementioned sensor, the specific components of the vehicle sensing module are not limited in the present invention, and in other embodiments, the vehicle sensing module may also be composed of other sensors with sensing function. Here, the sensing distance of the vehicle sensing module 10 may be adjusted to be greater than a preset multiple of the distance between adjacent street lamps on the current road according to actual requirements, for example, the street lamp distance is 25 meters, and then the distance of the radar transceiver transmitting the radar signal may be adjusted to be 50 meters.
The lighting notification module 20 includes a signal transmitting unit 21 and a signal receiving unit 22, where the signal transmitting unit 21 may be in communication connection with the vehicle sensing module 10, receive a vehicle sensing signal (e.g., a car _ arive (1) signal transmitted by the vehicle sensing module 10), and generate and transmit a lighting signal in response to the vehicle sensing signal. The signal receiving unit 22 is configured to receive a light-on signal, which includes receiving a light-on signal sent by a current street lamp control system and light-on signals sent by other street lamp control systems corresponding to the street lamps, and sending the received light-on signal to the light-on control module 30. The format (e.g., length, etc.) of the light-on signal received by the signal receiving unit 22 is the same as the format of the light-on signal sent by the preset signal sending unit 21. It is noted here that, in other embodiments, after receiving the light-on signal, the signal receiving unit 22 may also generate a prompt signal for indicating that the light-on signal is received by the current signal receiving unit 22, and send the prompt signal to the light-on control module 30, so that the light-on control module 30 performs the light-on control operation in response to the prompt signal.
The turn-on control module 30 is in communication connection with the street lamp, and after receiving the turn-on signal, the turn-on control module 30 generates a control signal for controlling the turn-on of the street lamp in response to the turn-on signal, and sends the control signal to the street lamp to control the street lamp to turn on the street lamp.
When the lighting control module 30 executes the lighting control operation, the brightness of the street lamp is adjusted to the preset working brightness. Here, the preset operation brightness may be a normal operation brightness of the street lamp at night, for example, a brightness of a region where the street lamp is located at morning and evening.
In this embodiment, when the lamp-on duration after the lamp-on control module performs the lamp-on control operation reaches the fourth preset duration, the lamp-off control operation is performed on the street lamp. Namely, the time for turning on the street lamp is limited, thereby achieving the effect of energy saving.
The fourth preset time is used for limiting the time for the street lamp to continuously turn on the lamp, so that the street lamp is turned off after the vehicle passes by, which is equivalent to the time delay for turning on the lamp. The specific value of the fourth preset duration can be determined according to habits of regions where the street lamps are located (including busy degrees of roads corresponding to the street lamps) when the street lamp control system of the embodiment is applied to road sections with different busy degrees in different regions. For example, the fourth preset time period may be 10s, when the light-on control module 30 performs the light-on control operation, the light-on time period is timed, and when the light-on time period reaches 10s, the light-off control operation is performed on the street lamp. Here, the lamp-off control operation includes adjusting the brightness of the street lamp to a preset energy-saving brightness, for example, adjusting the brightness of the street lamp to 15%.
Optionally, if the light-on control module receives the light-on signal again before the light-on duration reaches the fourth preset duration, the light-on duration is timed again, and the light-off control operation is performed on the street lamp when the re-timed light-on duration reaches the fourth preset duration.
That is, if the interval duration of the signal receiving unit receiving the two light-on signals successively is less than the fourth preset duration, the timing of the light-on duration is restarted when the second light-on signal is received. Here, the two lighting signals may be lighting signals transmitted in the incoming direction of the corresponding street lamps, and may be lighting signals transmitted by the corresponding signal transmitting modules after being sequentially sensed by the vehicle sensing modules at different street lamps in front during the driving process of the vehicle.
In this embodiment, the manner of sending the light-on signal by the signal sending unit and the format of the light-on signal are not limited, for example, the signal sending unit may send the light-on signal in a form of synchronous, asynchronous, reverse signal, etc., and send the light-on signal in any format in at least two frequency channels, and the formats of the light-on signal sent in the at least two frequency channels may be the same or different.
Optionally, the lighting signal is a wireless broadcast signal, that is, the street lamp control system of this embodiment performs communication of the lighting signal in a wireless broadcast manner, and after one signal sending unit sends the lighting signal, one or more signal receiving units receiving the lighting signal do not need to send reply communication, so that a tsunami caused by a communication error in a communication process can be avoided. Moreover, the light-on signal can also be a wireless broadcast signal without content, so that the communication of the light-on signal does not depend on a digital packet, and the problem that the communication is easy to be confused is effectively avoided. Here, the operating frequency of the radio broadcast signal may be 433MHz which is commonly used in the field of electric wave management in most countries or regions, but is not limited thereto.
Optionally, in order to ensure the communication quality of the light-on signal, a communication antenna may be disposed in the light-on notification module to enhance the communication stability of the light-on signal. For example, the signal transmitting unit includes a transmitting antenna, and the signal receiving unit includes a receiving antenna. In practical application, the working power of the open lamp transmitting antenna and the receiving antenna can be correspondingly increased or decreased according to the practical limit value indicated by relevant regulations of the region where the street lamp is located. And when the working power can not be increased, the length of the transmitting antenna or the receiving antenna can be adjusted to increase the transmission range of the signals transmitted by the transmitting antenna or increase the receiving range of the signals received by the receiving antenna, namely, the communication distance of the turn-on signal is increased. Here, the orientation of the transmitting antenna is the driving direction of the road corresponding to the street lamp, and the orientation of the receiving antenna is the coming direction of the road corresponding to the street lamp.
In practical application, the signal transmission range of the transmitting antenna and/or the receiving antenna can be set to be 250 meters to 400 meters, so that the lighting-on signal transmitted by the signal transmitting unit can be transmitted to the signal receiving unit which is output from the signal transmitting unit in the range of 250 meters to 400 meters in the driving direction, and the street lamps corresponding to the signal transmitting unit in the driving direction are turned on to illuminate the street lamps in the range of 250 meters to 400 meters, that is, the street lamps in the range of 250 meters to 400 meters in front of the vehicle are turned on to illuminate the street lamps in the driving direction.
In the street lamp control system of this embodiment, the signal transmitting unit transmits the light-on signal through at least two channels, and accordingly, the signal receiving unit receives the light-on signal in at least two channels, respectively. The street lamp control system of the embodiment of the invention adopts at least two channels to carry out the communication of the light-on signal, thereby avoiding the adoption of wired communication technology such as network cables or power supply lines, and avoiding the problems of high line cost, high maintenance cost and the like; moreover, a wireless communication technology such as a ZIGBEE technology which uses one channel for communication is not needed, so that the influence of the channel interference problem on the communication stability is reduced, and communication can be carried out through other channels even if one channel is disturbed; communication between the signal sending unit and the signal receiving unit (including the signal receiving unit corresponding to the current street lamp and the signal receiving units corresponding to a plurality of other street lamps) does not need to adopt an automatic frequency modulation method to avoid channel interference, so that the problem of channel frequency modulation failure is avoided; and a receiving address does not need to be sent, the communication quantity is less, the problem of communication overlapping is avoided, and the communication quality is ensured.
Optionally, the signal sending unit is configured to send a light-on signal with a signal duration greater than or equal to a first preset duration in at least two channels respectively; the signal receiving unit is used for receiving the light-on signals with the signal duration being greater than or equal to a first preset duration in at least two channels respectively.
The first preset duration may be determined according to a channel usage contract specification and device and line response time. For example, the first preset duration is 0.1 ms. The signal duration of the light-on signal is greater than or equal to a first preset duration, and the validity of signal communication can be guaranteed. Here, the complete lighting signal is a lighting signal received in at least two frequency channels, and then the lighting control unit can execute the lighting control operation only when the signal receiving unit receives the lighting signal with the signal duration being greater than or equal to the first preset duration from the at least two frequency channels. Of course, in other embodiments, the signal duration of the light-on signal may also be set to be less than the first preset duration while ensuring effective communication of the light-on signal.
Optionally, when the signal sending unit sends the light-on signal, the light-on signal is sent in at least two frequency channels in sequence by taking a second preset time length as an interval time length; the signal receiving unit is used for sending the light-on signals in at least two frequency channels in sequence by taking the second preset time length as the interval time length. The value of the second preset duration is not too large, for example, the second preset duration is 0.25 times of the first preset duration. Here, when the signal receiving unit receives the light-on signal with the signal duration greater than or equal to the first preset duration from the at least two frequency channels in sequence with the second preset duration as the interval duration, the light-on control unit may perform the light-on control operation. The receiving sequence of the signal receiving unit for receiving the light-on signals from the at least two frequency channels corresponds to the transmitting sequence of the signal transmitting unit for transmitting the light-on signals in the at least two frequency channels.
In addition, when the signal sending unit sends the light-on signals in at least two frequency channels, the second preset time intervals between sending the light-on signals in each frequency channel may not be equal. For example, the at least two frequency channels are A, B, C three frequency channels, the signal transmitting unit transmits the light-on signals in the a frequency channel and the B frequency channel in 0.2ms, and transmits the light-on signals in the B frequency channel and the C frequency channel in 0.3 ms.
In practical applications, the signal transmitting unit may also repeatedly transmit the light-on signal. For example, after the signal transmitting unit first transmits the light-on signal and waits for a number of first preset time periods, the light-on signal may be transmitted again.
As shown in fig. 1, in the embodiment of the present invention, the street lamp control system further includes a first detection module 40, configured to detect whether at least two channels are in an idle state before the signal sending unit sends the light-on signal; the signal sending unit is configured to send a light-on signal when the first detecting module 40 detects that at least two channels are in an idle state.
If the first detection module 40 detects that the duration of no signal in at least two channels reaches the third preset duration, it is determined that the at least two channels are in the idle state. Here, the third preset time period may be equal to the first preset time period. If any of the at least two channels is detected to have a signal, it cannot be determined that the at least two channels are in an idle state.
When the first detecting module 40 detects that at least two channels are in the idle state, a detection signal such as a NOT _ BUSY signal may be sent to the signal sending unit, so that the signal sending unit may perform the sending step of the light-on signal. In practical application, for a case where there are a plurality of (more than two) channels for transmitting the light-on signal, if it is detected that at least two channels of the plurality of channels are in an idle state, the light-on signal can be transmitted in the at least two channels in the idle state; that is, all channels are not required to be in the idle state, and the step of sending the turn-on signal may be performed as long as the number of channels in the idle state is greater than two.
Optionally, the street lamp control system further includes a second detection module 50, configured to detect whether at least two channels are interfered; the lighting control module is configured to perform a lighting control operation on the street lamp when the second detection module 50 detects that at least two channels are interfered. Wherein if the second detection module 50 detects an interference signal in any one of the at least two frequency channels, it is determined that the at least two frequency channels are interfered; and if the second detection module 50 detects that the duration of the idle state of the at least two channels reaches a fifth preset duration, determining that the at least two channels are interfered, which is a case that the at least two channels are maliciously occupied. Wherein, the fifth preset time period may be 5 min.
The signal receiving unit may not receive the light-on signal when at least two channels are interfered or occupied maliciously. For this case, when the second detection module 50 for interference prevention detection detects that at least two channels are interfered or occupied maliciously, a signal such as JAM _ ON is transmitted to the lighting control module to cause the lighting control module to perform the lighting control operation.
That is, when the second detection module 50 detects that at least two channels are interfered or occupied maliciously, the turn-on control module controls the street lamps to turn on continuously. In addition, if the second detection module 50 does not detect an interference signal and the first detection module 40 detects that at least two channels are idle in the process of controlling the continuous turn-on of the street lamp by the turn-on control module, it can be determined that the at least two channels are not occupied maliciously, the turn-on control module can stop controlling the continuous turn-on of the street lamp at the moment, and time the turn-on duration, and turn off the street lamp when the turn-on duration reaches the fourth preset duration.
Optionally, the lighting control module is further configured to perform a continuous lighting control operation on the street lamp when a duration that the signal receiving unit does not receive the lighting signal reaches a sixth preset duration. That is, the turn-on control module adopts a control method of turning on the lamp overtime, and when the signal receiving unit does not receive the turn-on signal for a long time, the signal receiving unit controls the street lamp to continuously turn on the lamp for illumination. When the duration that the signal receiving unit does not receive the turn-on signal in any one of the at least two channels reaches the sixth preset duration, the turn-on control module can perform continuous turn-on control operation on the street lamp.
For example, when the vehicle sensing module, the signal transmitting module or the signal receiving module corresponding to a large number of street lamps are damaged, the signal receiving module corresponding to the street lamp in the vehicle driving direction cannot receive the light-on signal, and the street lamp cannot be lighted up for illumination. By adopting the control method of turning on the lamp in time, even if the situation occurs, the street lamp can be effectively controlled to turn on the lamp for illuminating the vehicle.
The control method for turning on the lamp overtime can cause the waste of electric energy when the vehicle does not appear for a long time. Therefore, the signal sending unit of the street lamp control system of the embodiment is further configured to send the channel test signal in at least two channels with the seventh preset time period as the interval time period; the turn-on control module is also used for stopping the continuous turn-on control operation of the street lamp when the signal receiving unit receives the channel detection signals in at least two channels. The signal receiving unit continuously detects signals in at least two channels in the process of carrying out the turn-on control operation on the street lamp, and the turn-on control module stops carrying out the continuous turn-on control operation on the street lamp when the signal receiving unit receives the channel detection signals in any channel. Here, the seventh preset time period is less than the sixth preset time period, for example, the sixth preset time period may be 30min, and the seventh preset time period may be 15 min.
For example, the channel test signal may be a channel pulse, that is, every interval of the seventh preset duration, the signal sending unit may send a channel pulse in at least two channels, so that the signal receiving module corresponding to the street lamp in the driving direction does not receive a signal for too long, and the controlled module is controlled to turn on the lamp by the control method of turning on the lamp overtime. When the signal transmitting unit transmits the channel pulses in at least two channels, a certain time interval is needed between every two channel transmission channel pulses so as to avoid the phenomenon that the lamp is turned on due to mistaken touch.
In practical applications, the first detection module 40 and the second detection module 50 may be integrated into a detection module, which is used to detect whether signals exist in at least two channels, detect whether a signal receiving unit receives a light-on signal or a channel detection signal in at least two channels, and store a detection record, so as to implement the corresponding detection functions of the first detection module 40 and the second detection module 50, and enable the light-on control module to determine whether to execute a continuous light-on control operation according to the detection record. In addition, the detection record can also be used for performing system self-check, for example, if the detection record shows that the duration of the signal receiving unit not receiving the channel detection signal in any of the at least two channels exceeds, it is determined that the signal receiving unit has a fault, and fault reporting can be performed to prompt a worker to maintain the current system.
According to the street lamp control system provided by the embodiment of the invention, whether a vehicle is in the coming direction of the road corresponding to the street lamp is sensed, and the lamp-on signal is sent when the vehicle is sensed, so that the street lamp in the current street lamp or the driving direction of the vehicle is lighted when the corresponding signal receiving unit receives the lamp-on signal, and the street lamp can be effectively controlled to be lighted on when the vehicle comes at night.
In addition, the street lamp control system of the embodiment of the invention effectively realizes effective balance between the illumination effect and energy conservation by carrying out control methods such as lamp-on delay, overtime lamp-on, anti-interference detection and the like on the street lamp.
It should be noted that, according to the implementation requirement, each component described in the present application can be divided into more components, and two or more components or parts of components can be combined into a new component to achieve the purpose of the present invention.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
