Description

Technical Field

[0001] The present application relates to the field of sensors, and in particular to an induction lighting system. Background Art

[0002] Existing induction lighting lamps mainly include voice-controlled lamps, radar induction lamps and human body induction lamps. However, radar induction lamps usually have problems such as short sensing distance, poor stability and short service life. Radar induction lamps with stable performance are generally expensive and easily triggered by mistake. The sensing probe and lamp of the human body infrared induction lamp usually need to be installed separately, and the probe and the lamp must be at a distance of more than 0.5 meters. Improper installation may cause the temperature around the sensing probe to rise due to the heat of the lamp, thereby reducing the detection sensitivity. The ambient temperature and smoke concentration in the environment have a greater impact on the sensitivity of the human body infrared induction lamp. Voice-controlled lamps are easily triggered by ambient noise and light up by mistake. Especially on thunderstorm nights, almost all voice-controlled lamps in the thunderstorm area will be frequently awakened and lit by thunder, which not only wastes power but also shortens the service life of the bulb.

[0005] Through the judgment mechanism of multiple sensing devices, the lighting can be accurately responded to human activities, avoiding false touches caused by temperature, smoke, etc., and improving the sensitivity of the sensor lamp.

[0030] The induction lighting system 100 is initialized after installation. Specifically, a dedicated device is used to connect to the lighting unit 120 via the remote wireless communication module 123, and then the MAC address of each lighting unit 120 is modified according to the installation floor information and specific coding rules. The higher the floor, the larger the MAC address value, and the key is modified uniformly.

[0031] Then, the MAC addresses of the lighting units 120 installed on other floors are searched through the remote wireless communication module 123. Since the remote wireless communication module 123 has a strong ability to penetrate walls, it is required to search for at least 4 MAC addresses of the induction lights installed on other floors. If the signal strength of the remote wireless communication module 123 of the lighting units 120 on other floors that are searched meets the threshold of stable signal transmission, a wireless connection is established with the lighting unit 120, and the total number of connected lighting units 120 is written into the corresponding register, and the self-test time of the lighting unit 120 is set, thereby completing the initialization setting. After the initialization setting is completed, the induction lighting system 100 enters the network standby mode.

[0032] See also Figure 1 , Figure 1 1 is a schematic diagram of the structure of an embodiment of an induction lighting system 100 provided in the present application, the lighting system comprising:

[0033] The power supply unit 110 is directly connected to the 220V mains to supply power to the entire induction lighting system 100. The power supply unit 110 includes a voltage converter to convert the 220V voltage into a voltage suitable for each circuit for power supply, such as converting AC 220V into DC 5V, or converting AC 220V into DC 3.3V.

[0034] Specifically, the voltage converter includes a rectifier bridge circuit and a step-down circuit, etc.

[0035] At least two lighting units 120 include a lighting device 121, a sensing device 122 and a long-range wireless communication module 123. The sensing device 122 includes an infrared sensing device 1221, a sound sensing device 1222 and a first light sensing device 1223. The infrared sensing device 1221, the sound sensing device 1222 and the first light sensing device 1223 are electrically connected to the long-range wireless communication module 123, respectively. The lighting device 121 is electrically connected to the long-range wireless communication module 123 and the power supply unit 110, respectively. The long-range wireless communication modules 123 on each floor are communicatively connected to each other, and the long-range wireless communication module 123 is electrically connected to the power supply unit 110.

[0036] The lighting device 121 is used for lighting in the passage, and the lighting brightness should at least ensure that people can see obstacles and steps clearly when walking.

[0037] Optionally, the power supply unit 110 includes a voltage stabilizing circuit corresponding to each lighting unit 120, and the voltage stabilizing circuit is used to convert the 220V voltage into a voltage suitable for each lighting unit 120 for power supply, such as converting AC 220V into DC 5V, or converting AC 220V into DC 3.3V, etc.

[0038] The sensing device 122 is used to collect various types of information in the channel and convert the collected information into analog or digital signals. The signal processing circuit then modulates the various types of signals into electrical signals, such as level signals, that can be effectively recognized by the remote wireless communication module 123.

[0039] Specifically, the sensing device 122 includes an infrared sensing device 1221, a sound sensing device 1222 and a first light sensing device 1223, which are respectively used to collect infrared rays, sounds and ambient brightness of pedestrians in the channel.

[0040] The infrared sensing device 1221 generates an electrical signal based on the collected infrared rays of the human body, and sends the electrical signal to the remote wireless communication module 123. Optionally, the infrared sensing device 1221 is a pyroelectric sensor, which consists of a pyroelectric detection element and a preamplifier. The pyroelectric detection element is the core component of the sensor, which is made by polarizing the two sides of the pyroelectric crystal after metal electrodes are plated. When the preamplifier receives the weak current signal generated by the pyroelectric detection element, it converts it into a useful voltage signal output. In addition, the pyroelectric sensor is also equipped with a bandpass filter, which is encapsulated at the top of the sensor housing and can selectively allow infrared radiation of a specific wavelength to pass, thereby improving the sensitivity and accuracy of the sensor.

[0041] The sound sensing device 1222 generates an electrical signal based on the collected sound and sends the electrical signal to the remote wireless communication module 123. Optionally, the sound sensing device 1222 is a microphone (MIC), which can be a dynamic microphone, a condenser microphone, an electret microphone or a piezoelectric microphone, etc., and the present application does not impose specific restrictions on this. The sound sensing device 1222 is a device for sound capture and conversion. Its main function is to convert sound waves (sound vibrations) into electrical signals for transmission, amplification, recording or further processing.

[0042] The first light sensing device 1223 generates an electrical signal based on the collected ambient brightness, and sends the electrical signal to the remote wireless communication module 123. Optionally, the first light sensing device 1223 is a photoresistor. Under dark conditions, most of the electrons inside the photoresistor are valence band electrons that cannot move freely. At this time, the resistance of the photoresistor is very high. When there is light of a suitable wavelength, the valence band electrons in the photoresistor absorb photon energy and transition to the conduction band, becoming free electrons that can conduct electricity, and leaving a hole in the valence band. The greater the light intensity, the more electron-hole pairs are excited, and the lower the resistance of the photoresistor. When the light is removed, the conduction band electrons recombine with the valence band holes, and the resistance of the photoresistor increases. The remote wireless communication module 123 can know the current ambient brightness by reading the voltage value of the first light sensing device 1223.

[0043] Optionally, in this embodiment, the remote wireless communication module 123 is a WiFi Halow module, which is a wireless communication module based on Wi-Fi Halow technology, working in the Sub-1GHz frequency band, and has multiple advantages such as long distance, low power consumption, and large capacity. Compared with traditional Wi-Fi technology, Wi-Fi Halow has significantly improved the transmission distance, covering a distance of more than 1 kilometer, which is about ten times the transmission distance of traditional Wi-Fi. At the same time, it also has better signal penetration and anti-interference performance, and is suitable for network construction in more complex building environments. The remote wireless communication module 123 analyzes the electrical signals collected by the sensing device 122 to determine whether there is any human activity in the environment where the current lighting unit 120 is located. At the same time, each lighting unit 120 is connected to each other through the remote wireless communication module 123 to transmit information to each other.

[0044] The remote wireless communication module 123 turns on the lighting device 121 for lighting in response to the personnel activity behavior collected by the sensing device 122 .

[0045] When the analysis result of the remote wireless communication module 123 on the electrical signal collected by the sensing device 122 is that there is human activity, the remote wireless communication module 123 controls the lighting device 121 to turn on and illuminate, thereby realizing sensing lighting according to human activity occurring in the channel.

[0046] Optionally, the remote wireless communication module 123 determines whether there is human activity based on the received electrical signal, and in response to the determination result that there is human activity, sends a lighting signal to the lighting device 121, and the lighting device 121 illuminates in response to the lighting signal.

[0047] The lighting device 121 is electrically connected to the remote wireless communication module 123 and the power supply unit 110 respectively. When the remote wireless communication module 123 sends a lighting signal to the lighting device 121, the lighting device 121 responds to the lighting signal and performs lighting based on the power provided by the power supply unit 110.

[0048] Optionally, the remote wireless communication module 123 sends a lighting signal to the lighting device 121 in response to the electrical signal sent by the first light sensing device 1223 being smaller than a first threshold and the electrical signal sent by the infrared sensing device 1221 being not smaller than a second threshold.

[0049] When the brightness of the environment is lower than a certain brightness value, people in the passage cannot rely on natural light to pass through the corridor. At this time, the electrical signal sent by the first light sensing device 1223 will not reach the first threshold. When a pedestrian passes through the passage, the infrared rays emitted by the human body will be captured by the infrared sensing device 1221, and an electrical signal not less than the second threshold will be formed and sent to the remote wireless communication module 123. The remote wireless communication module 123 responds to the electrical signal sent by the first light sensing device 1223 being less than the first threshold, and the electrical signal sent by the infrared sensing device 1221 being not less than the second threshold, that is, when the current environment brightness is too low and a pedestrian passes by, a lighting signal is sent to the lighting device 121 to achieve induction lighting.

[0050] Optionally, the remote wireless communication module 123 sends a lighting signal to the lighting device 121 in response to the electrical signal sent by the first light sensing device 1223 being less than the first threshold and the electrical signal sent by the sound sensing device 1222 being not less than the third threshold.

[0051] When the brightness of the environment is lower than a certain brightness value, people in the passage cannot rely on natural light to pass through the corridor. At this time, the electrical signal sent by the first light sensing device 1223 will not reach the first threshold. When pedestrians pass through the passage, the sounds made by pedestrians, such as talking and footsteps, will be captured by the sound sensing device 1222, and form an electrical signal not less than the third threshold and send it to the remote wireless communication module 123. In response to the electrical signal sent by the first light sensing device 1223 being less than the first threshold, and the electrical signal sent by the sound sensing device 1222 being not less than the third threshold, that is, when the current environment brightness is too low and pedestrians pass by, the remote wireless communication module 123 sends a lighting signal to the lighting device 121 to achieve inductive lighting.

[0052] By sensing the ambient brightness, the lighting unit 120 can be triggered when the ambient brightness is lower than a first threshold value, thereby avoiding triggering the lighting unit 120 when there is sufficient natural light during the day and no lighting is needed, causing a waste of electricity and saving electricity costs.

[0053] Optionally, in response to the electrical signal sent by the first light sensing device 1223 being less than the first threshold value and the electrical signal sent by the sound sensing device 1222 being not less than the third threshold value, the remote wireless communication module 123 sends a false trigger verification signal to the other layer remote wireless communication module 123. If the remote wireless communication module 123 does not receive the false trigger verification signal sent by the other layer remote wireless communication module 123, it sends a lighting signal to the lighting device 121.

[0054] In special weather such as thunderstorms, due to the dark sky and loud thunder, the induction-type lighting lamps of the entire building are easily repeatedly triggered by thunder. When the ambient brightness is lower than the first threshold and the sound is not less than the third threshold, the remote wireless communication module 123 sends a false trigger verification signal to the lighting units 120 on other floors that are connected to it for communication. If the remote wireless communication module 123 receives a false trigger verification signal sent from the lighting units 120 on other floors, it means that the induction lights on at least two floors are triggered at the same time, and there may be a false induction trigger. If the false trigger verification signal sent by the remote wireless communication module 123 on other floors is not received, it means that the lighting unit 120 is triggered normally, and the remote wireless communication module 123 sends a lighting signal to the lighting device 121.

[0055] The false triggering verification between the lighting units 120 on each floor is performed through the false triggering verification signal to avoid the influence of special circumstances such as thunderstorms and construction, which may cause the lighting units 120 on each floor in the channel to be falsely triggered, resulting in loss of life and waste of electricity resources.

[0056] Specifically, see Figure 2 , the lighting device 121 includes a relay 1211 and a light bulb 1212 .

[0057] The first end of relay 1211 is connected to the remote wireless communication module 123, the second end of relay 1211 is connected to the power supply unit 110, and the third end of relay 1211 is connected to the light bulb 1212. In response to receiving a lighting signal at the first end, relay 1211 connects the first end and the third end, and the light bulb 1212 emits light for illumination.

[0058] The relay 1211 controls the conduction between the first end and the third end through the electrical signal of the remote wireless communication module 123, so that the power supply unit 110 supplies power to the light bulb 1212, thereby completing the lighting. The relay 1211 also controls the disconnection between the first end and the third end through the electrical signal of the remote wireless communication module 123, thereby ending the lighting.

[0059] Optionally, the type of bulb 1212 includes but is not limited to an incandescent lamp, a fluorescent lamp, an LED lamp, a halogen lamp, a xenon lamp or an energy-saving lamp.

[0060] The voltage output by the power supply unit 110 to the lighting device 121 is a voltage value adapted to the light bulb 1212 .

[0061] Furthermore, the induction lighting system 100 further includes:

[0062] The remote server 140 is used to store various types of data and can be operated by a staff member to send instructions to the relay transceiver 130 to achieve control over each lighting unit 120.

[0063] The relay transceiver 130 is communicatively connected to the remote server 140 and is communicatively connected to the remote wireless communication module 123 of at least the top floor lighting unit 120, and is used to receive the command information sent by the remote server 140 and forward it to the lighting units 120 on each floor, or to receive the information sent by the lighting units 120 on each floor and forward it to the remote server 140.

[0064] The relay transceiver 130 is an information transfer station between each lighting unit 120 and the remote server 140. By being equipped with an antenna, the relay transceiver 130 can establish a communication connection with the remote server 140 at a distance greater than one kilometer. The relay transceiver 130 also includes a long-range wireless communication module 123, and the long-range wireless communication module 123 is at least in communication connection with the long-range wireless communication module 123 in the lighting unit 120 installed on the top floor, so that the long-range wireless communication module 123 on each floor can transmit information to the relay transceiver 130 through the long-range wireless communication module 123 on the top floor.

[0065] During the information transmission process, the instructions issued by the remote server 140 are transferred via the relay transceiver 130 and sent to the remote wireless communication module 123 on the top layer. The remote wireless communication module 123 on the top layer then transmits the instructions downward from the top layer to the bottom layer by layer through the communication connection established between the remote wireless communication modules 123 on each layer. The information reported by each lighting unit 120 is directly sent by the corresponding remote wireless communication module 123 to the lighting unit 120 on the highest floor with which the lighting unit 120 directly establishes a communication connection, and is forwarded upward layer by layer. Each forwarding follows the rule of forwarding to the highest floor with which the lighting unit 120 can directly communicate, until it is forwarded to the remote wireless communication module 123 of the lighting unit 120 on the top floor, and then forwarded to the remote server 140 by the remote wireless communication module 123 on the top floor via the relay transceiver 130.

[0066] This information transmission method can reduce the number of information transmissions and reduce the transcoding errors and other problems caused during the information transmission process. At the same time, it can also quickly complete the information transmission between the remote wireless communication modules 123 in the communication network, improve the information transmission efficiency, and reduce delays.

[0067] Optionally, the sensing device 122 further includes a second light sensing device 1224 , which is electrically connected to the remote wireless communication module 123 and generates an electrical signal based on the collected brightness of the lighting device 121 .

[0068] Specifically, the second light sensing device 1224 is a photoresistor. Under dark conditions, most of the electrons inside the photoresistor are valence band electrons that cannot move freely, and the resistance of the photoresistor is very high. When there is light of a suitable wavelength, the valence band electrons in the photoresistor absorb photon energy and transition to the conduction band, becoming free electrons that can conduct electricity, and leaving a hole in the valence band. The greater the light intensity, the more electron-hole pairs are excited, and the lower the resistance of the photoresistor. When the light is removed, the conduction band electrons recombine with the valence band holes, and the resistance of the photoresistor increases. The remote wireless communication module 123 can know the brightness of the current lighting device 121 by reading the voltage value of the second light sensing device 1224.

[0069] In response to the lighting device 121 not lighting for the preset lighting time and the electrical signal generated by the corresponding second light sensing device 1224 being less than the fourth threshold, each remote wireless communication module 123 sends the corresponding lighting unit 120 information to the relay transceiver 130, and the relay transceiver 130 forwards the lighting unit 120 information to the remote server 140.

[0070] When the lighting device 121 is lighting for less than the preset lighting time, the lighting device 121 should be in the lighting state, and the brightness value collected by the second light sensing device 1224 is relatively high, and should be at least equal to the fourth threshold. If the electrical signal generated by the second light sensing device 1224 is less than the fourth threshold, it means that the lighting device 121 is not bright enough or does not emit light when it should, and there may be a fault in the lighting unit 120.

[0071] For a lighting unit 120 that may have a fault, the remote wireless communication module 123 in the lighting unit 120 transmits the information of the lighting unit 120 via the route of the top lighting unit 120-relay transceiver 130-remote server 140, and the remote server 140 records and processes the information so that the faulty lighting unit 120 can be found and repaired in time. Frequent inspections and one-by-one screening are avoided, which is conducive to improving the efficiency of maintenance work and reducing maintenance costs.

[0072] Furthermore, the relay transceiver 130 forwards the self-test instruction sent by the remote server 140 to the top-level lighting unit 120, and each layer of lighting unit 120 transmits the self-test instruction layer by layer from the top layer downward, and sends a lighting signal to the lighting device 121, and the lighting device 121 performs lighting.

[0073] The remote server 140 sends a self-test instruction to the relay transceiver 130 according to a preset self-test time or a manually input self-test signal. The lighting units 120 on each floor of the relay transceiver 130 transmit the self-test signal step by step to perform self-test.

[0074] Or, when the induction lighting system 100 is initialized, the self-inspection time of the induction lighting system 100 is set, such as 11 o'clock at night on the 1st of each month. When the self-inspection time is reached, the relay transceiver 130 transmits the self-inspection signal to the lighting units 120 on each floor step by step to perform self-inspection.

[0075] The induction lighting system 100 can perform an automatic self-check at a preset time or a manual self-check under manual instruction to check each lighting unit 120 of the channel to check whether there is a lighting unit 120 with abnormal lighting. The information of the lighting unit 120 with abnormal lighting is reported to the remote server 140 for processing.

[0076] Optionally, after the lighting unit 120 on each floor illuminates in response to the human activity behavior collected by the sensing device 122, the current moment information of the lighting unit 120 is sent to the relay transceiver 130, and the remote server 140 generates the human activity path based on the current moment information of the lighting unit 120 forwarded by the relay transceiver 130.

[0077] When the lighting unit 120 is triggered, the time, number and other information when the lighting unit 120 is triggered are reported to the remote server 140 for recording. According to the time when the lighting unit 120 at each position is triggered, the activity path of the pedestrians in the channel can be formed.

[0078] In the above-mentioned induction lighting system 100, the lighting unit 120 stops lighting in response to the end of the preset lighting time.

[0079] Different from the prior art, the present application provides an induction lighting system 100, which uses a combination of infrared, sound and light sensing methods, and multiple sensors work together to enable the lighting unit 120 to accurately sense human activities and illuminate when the light is low. Through the remote wireless communication module 123, an information communication network is constructed, and information can be transmitted and processed between the lighting units 120 on each floor and between the lighting units 120 and the remote server 140, so as to realize functions such as anti-false triggering and self-checking. The anti-false triggering mechanism can effectively avoid the triggering of the lighting device 121 in special situations such as construction and thunderstorms, effectively protect the life of the lighting unit 120, and reduce electricity costs. Through the self-checking function, the information of the lighting unit 120 with faults can be reported in time so that maintenance personnel can repair it in time. By reporting and recording the information of each lighting unit 120 being triggered, the activity trajectory of the people in the passage can be formed. In the event of a theft or other public security incident, by retrieving the activity trajectory data of the people in the evacuation stairwell, it can be helpful to analyze the event process, thereby playing a role in auxiliary security.
