[0044] Figure 1 It is a schematic diagram of the system architecture of the present invention. DETAILED DESCRIPTION
[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0046] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a component centered. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a component centered. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a component centered. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.
[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0048] Please also see Figure 1 , this embodiment provides a lamp interaction system based on Internet monitoring, including a plurality of lighting elements, the lighting elements are specifically street lamps, there is a communication connection between two lighting elements in an adjacent relationship, the adjacent relationship is specifically that there is an intersection between the illuminated areas of the two lighting elements, each lighting element includes a first lighting state and a second lighting state, wherein the brightness of the first lighting state is less than the brightness of the second lighting state. The lighting element includes a collection module, an extraction module, a storage module, and a comparison module. The present invention is suitable for roads with low traffic demand in mountainous areas. When no one passes, each lighting element maintains the first lighting state to reduce the power demand of the lighting element. When the collection module of any lighting element collects footsteps, it generates a brightening signal to the lighting element adjacent to the lighting element, so that the lighting element that is currently passing by pedestrians and is predicted to have pedestrians passing by maintains the brighter second lighting state, providing good lighting conditions for pedestrians. When the pedestrians leave, the corresponding lighting element is restored to the second lighting state, taking into account both the lighting demand and the energy-saving demand.
[0049] The lighting element can be used as a transmitter or a receiver. When one of the acquisition modules collects footsteps, the corresponding lighting element is used as the transmitter, and the lighting element that is adjacent to the transmitter is used as the receiver. The transmitter and the receiver are connected in communication. In actual use, two adjacent lighting elements communicate by pre-buried cables to ensure the stability of the signal in the mountain environment. When the lighting element is used as the receiver, the acquisition module collects footsteps to define them as second footstep information. The extraction module obtains and extracts at least one set of second footstep sub-information from the second footstep information. Each second footstep sub-information represents the footstep data of different pedestrians, and generates a footstep signal to the transmitter. Due to the difference in walking speed between pedestrians, when pedestrians pass by a lighting element, the walking process of each pedestrian can be regarded as a periodic change in time, and the volume changes from increasing to decreasing. The footstep data of multiple pedestrians can be split according to this characteristic. If there are multiple people walking synchronously, the change period of their footstep data is the same, but due to their synchronous movement, they can also be regarded as one pedestrian for processing.
[0050] When the lighting element is used as the transmitting end, the collection module collects the footsteps to be defined as the first footstep information, and generates a brightening signal to keep the lighting element and the lighting element of the receiving end in the second lighting state, so as to provide convenience for pedestrians to walk in advance. The extraction module obtains and extracts at least one set of first footstep information from the first footstep information and records it in the storage module. Each first footstep information represents the footstep data of different pedestrians. The comparison module receives the footstep signal to obtain the second footstep information, and compares the second footstep information with each first footstep information. If the similarity is higher than the preset footstep threshold, a clearing signal is generated to clear the corresponding first footstep information in the storage module. The similarity comparison is mainly because the sound data will be affected by the ground medium, such as frequency. When all the first footstep information in the storage module is cleared, it means that all pedestrians have left the current transmitting end. Then, a dimming signal is generated to switch the transmitting end and the receiving end that has not generated the footstep signal to the first lighting state, so that the receiving end lighting element where no pedestrians have arrived and the current transmitting end lighting element are adjusted to a state with lower lighting brightness. When comparing the first step information with the second step information, data such as frequency, amplitude, variation period, and position of the maximum volume within the variation period may be used.
[0051] The storage module is configured with an information database, which is used to record pedestrian information and recording time. The pedestrian information specifically includes the first footstep information. The recording time reflects the moment when the corresponding pedestrian information is recorded. When the storage module receives a clear signal, the corresponding pedestrian information and recording time are cleared synchronously. The lighting element is configured with a first abnormal feedback module. If the pedestrian information is not cleared within the preset waiting time, the first abnormal feedback module generates an abnormal feedback signal. The monitoring center can retrieve the surrounding monitoring according to the received abnormal feedback signal, observe the movement information of the pedestrian, and provide timely rescue if the pedestrian is found to be in danger, such as slipping, falling off a cliff, and other emergency situations.
[0052] The information database also includes historical arrival data. When the comparison module generates a clear signal, the span time is calculated to define the historical arrival duration and expand the historical arrival data. Then, each historical arrival data is transmitted and stored in the information database of the receiving end. The comparison module is configured with a simplified comparison strategy, which includes simplified comparison steps:
[0053] Step 1: Count the number of historical arrival durations in the historical arrival data to define it as a cumulative number. If the cumulative number exceeds a preset number, a simplified signal is generated to the receiving end comparison module.
[0054] Step 2: The transmitter comparison module obtains the historical arrival time and generates a predicted arrival time period to the receiver comparison module. If the receiver acquisition module detects footsteps within the predicted arrival time period, it generates a clear signal and uses the first footstep information as the second footstep information.
[0055] The purpose of setting up a simplified strategy is to reduce the workload of each component. When there are a certain number of samples recorded for the same pedestrian, the time it takes to walk to the next lighting component can be inferred based on the length of the distance and the pedestrian's walking speed. The simplified strategy can be used to reduce the amount of calculation for each lighting component.
[0056] The simplified comparison strategy is configured with execution conditions. When the execution conditions are met, the simplified comparison strategy is executed. The execution conditions are specifically that the number of receiving ends corresponding to the transmitter is less than the preset number of receiving ends, and the number of pedestrian information in the information database of the transmitter is less than the preset number of pedestrians. The setting of the execution conditions can enhance the accuracy of the simplified strategy when it is used. The number of receiving ends corresponding to the transmitter can reflect the number of forks in the location of the transmitter lighting element. If the number of forks is large, the predicted data needs to be transmitted to multiple receiving ends for comparison. The environment of each fork is different, and pedestrians need to spend more time to identify when walking, which is easy to produce large errors. Therefore, the simplified strategy is not applicable to this location. The number of pedestrian information in the information database of the transmitter reflects the number of pedestrians who have arrived at this transmitter lighting element and have not yet arrived at the receiving end lighting element. If the number of people is large, the predicted time between each pedestrian is easy to overlap, so the simplified strategy is not applicable. In addition, the setting of the execution conditions is equivalent to adding verification points in the execution process of the simplified strategy, and these verification points are set at locations where errors are likely to occur, which can reduce the workload of each module and improve the accuracy of detection.
[0057] The lighting element is equipped with a second abnormal feedback module, which obtains the first footstep information and extracts frequency data from it for comparison. The frequency data reflects the speed of the pedestrian's movement. If the change rate of the frequency data is greater than the preset change rate, the second abnormal feedback module generates an abnormal signal to switch each lighting element to the second lighting state. As mountain roads are prone to accidents, such as sudden natural disasters, wild animals, etc., when a sudden change in frequency data is detected, that is, when the pedestrian suddenly accelerates, the brightness of each lighting element is increased to provide good lighting conditions for the evacuation of pedestrians.
[0058] The lighting element is equipped with an ambient sound database, which stores multiple sets of ambient sound information, the ambient sound information includes multiple sets of ambient sound sub-information, each of which corresponds to the total amount of ambient sound bands at a preset frequency within a time interval;
[0059] The collection module is configured with a footstep sound collection strategy, and the footstep sound collection strategy is configured with footstep sound collection steps:
[0060] Step 1: The acquisition module acquires real-time sound signals and pre-processes the real-time sound signals to obtain multiple sound bands at preset frequencies;
[0061] Step 2: retrieve the ambient sound sub-information corresponding to the time point of the current real-time sound information collection, eliminate the ambient sound band, and select the sound band whose sound band intensity periodically decays from the remaining sound bands of the real-time sound information and define it as the first footstep information or the second footstep information.
[0062] Preprocessing includes filtering, A / D conversion, pre-emphasis, framing and windowing, and endpoint detection;
[0063] The filtering uses FIR filter to filter out non-audio components in the signal to maximize the signal-to-noise ratio of the input signal;
[0064] A / D conversion is the process of converting analog signals into digital signals;
[0065] Pre-emphasis is to emphasize the high-frequency part of the signal, enhance the high-frequency resolution of the sound signal, and facilitate the subsequent spectrum analysis; select a first-order FIR high-pass digital filter for pre-emphasis processing;
[0066] Framing and windowing is to divide the sound signal into very small time periods, namely frames, and then perform windowing on the framed sound signal, using a Hamming window for windowing.
[0067] Endpoint detection is set in the sound signal to distinguish the ambient sound from the footstep sound and accurately determine the starting and ending points of the sound signal.
[0068] The lighting element is equipped with a visibility sensing module and a color temperature adjustment module. The visibility sensing module includes a visibility sensor, a temperature and humidity sensor, and a microprocessor. The visibility sensor is used to collect particle concentration data in the environment. The temperature and humidity sensor is used to collect temperature and humidity data in the environment. The microprocessor is used to calculate the environmental visibility index according to the particle concentration data and the temperature and humidity data in the environment.
[0069] The microprocessor is connected to the color temperature adjustment module. The microprocessor is configured with a visibility comparison strategy. The visibility comparison strategy includes a comparison threshold. When the environmental visibility index is greater than the comparison threshold, the microprocessor controls the color temperature adjustment module to reduce the output color temperature of the lighting element; when the environmental visibility index is less than the comparison threshold, the microprocessor controls the color temperature adjustment module to increase the output color temperature of the lighting element.
[0070] The color temperature adjustment module is configured with a color temperature adjustment strategy, and the color temperature adjustment strategy is configured with a color temperature adjustment algorithm. The calculation formula of the color temperature adjustment algorithm is:
[0071] Y=β∑Ai*Bi
[0072] Pi=P0[exp(Y / 2)-1] -1+β*{(Smax-Smin) / Save+(Wmax-Wmin) / Wave}
[0073] Among them, Y is the particle concentration index, Ai is the preset weight parameter corresponding to each type of particle, and Bi is the particle concentration;
[0074] Among them, Pi is the adjusted color temperature value, P0 is the initial color temperature value, β is a random parameter, Smax is the maximum humidity value, Smin is the minimum humidity value, Save is the average humidity value, Wmax is the maximum temperature value, Wmin is the maximum temperature value, and Wave is the average temperature value.
[0075] The random parameter β is set with multiple influencing factors, including air flow rate and lighting element brightness.
[0076] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
