Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a multi-channel narrowband communication method and a system thereof and lighting equipment. Background Art

[0002] Traditional communication technology usually has the problem of co-frequency interference, that is, when communicating in the same frequency band channel (channel) and sending signals at the same time, the receiver often causes interference to the received signal, or causes communication data to be blocked / queued, or even no signal can be received. The principle of this interference is mainly: when the receiver is in the process of receiving and decoding data, another transmitter happens to send data at the same frequency, which will disturb / affect the accuracy of the receiver's data reception. For example, there are two transmitters A and B, and a receiver C. When transmitters A and B use the same frequency band and transmit wireless information at the same time, the receiver C will not be able to receive the information sent by the transmitters A and B, or the information will be wrong due to interference in reception. In order to solve this kind of problem, some manufacturers currently use the coordinator solution, that is, to allocate the timing transmission or reception through the coordinator, but this will lead to a significant increase in costs.

[0003] Another solution on the market is to first distinguish the information in the same communication frequency band by encoding the address, and then load the data information that needs to be communicated to achieve the marking and identification of the data information. However, the communication speed of this solution is relatively slow, mainly because when multiple machines communicate, it will cause communication data congestion / queue phenomenon, which will cause interference to the receiver or the receiver will not receive any signal.

[0004] In addition, information in the same communication frequency band is distinguished by coded addresses. As time goes by, the receiving address mark is very likely to change or become invalid, resulting in no signal reception or loss of contact with the device. Summary of the invention

[0079] Schematic method

[0080] like Figure 1 As shown, a multi-channel narrowband communication method according to an embodiment of the present invention is described, which is used to solve the problem of data congestion or data failure in current communication methods, that is, to solve the problem of same-frequency communication interference in current communication methods. Specifically, Figure 1 As shown, the multi-channel narrowband communication method comprises the steps of:

[0081] Dividing a communication frequency band into at least two narrow-band communication frequency bands, wherein the communication frequencies of each narrow-band communication frequency band are different from each other, and sending at least one first channel signal in one of the narrow-band communication frequency bands; and

[0082] The first channel signal is received in the narrowband communication frequency band corresponding to the first channel signal, so as to distinguish different channel signals in the same communication frequency band by using different narrowband communication frequency bands without the need of a coordinator.

[0083] Furthermore, the multi-channel narrowband communication method comprises the steps of:

[0084] S110: dividing a communication frequency band into at least two narrow-band communication frequency bands, wherein the communication frequencies of each narrow-band communication frequency band are different from each other, so that signals can communicate without interference in the same narrow-band communication frequency band; and

[0085] S120: Switching one narrowband communication frequency band to another narrowband communication frequency band through frequency hopping technology, so that signals can communicate between different narrowband communication frequency bands without interference.

[0086] Exemplarily, the European 868MHZ frequency band (i.e., bandwidth of 863-879MHZ) is used as an example for description. The communication frequency band is divided into N very narrow frequency bands (i.e., narrow-band communication frequency bands) within the allowed frequency band (i.e., frequency bandwidth). For example, the allowed frequency bandwidth is 6M, which is divided into 32 narrow-band communication frequency bands. Then, the allowed frequency bandwidth for transmission and reception of each narrow-band communication frequency band (i.e., channel) is 6 / 32=0.1875MHZ. Since the communication frequencies of each narrow-band communication frequency band are different (i.e., the communication frequency ranges of different narrow-band communication frequency bands do not have any intersection or overlap), there will be no interference when signals are sent simultaneously in different narrow-band communication frequency bands. In this way, each narrow-band communication frequency band has a pre-set communication frequency band, which is equivalent to establishing multiple different high-speed channels, and there will be no communication conflicts or co-frequency interference problems. In addition, the communication technology of the narrow-band communication frequency band can also reduce interference to other devices, so as to achieve the purpose of mutual non-interference. It is understandable that the communication frequency range of the communication frequency band can also be defined as a low-rate wireless personal area network LR-WPSN such as the United States 915MHZ (ie, a bandwidth of 896-960MHZ), and can also be defined as a 2.4G frequency band or a 5G frequency band, etc.

[0087] It can be understood that only signals with the same communication frequency as the narrowband communication frequency band can pass through the narrowband communication frequency band, and the same communication frequency signal passing through the narrowband communication frequency band can only be received by a receiver that matches the narrowband communication frequency band, that is, each narrowband communication frequency band can represent signals with different communication frequencies, and the transmission of signals with different communication frequencies is unique. In other words, only devices in the same narrowband communication frequency band can communicate with each other, thereby preventing interference from devices in other frequency bands. Therefore, through the multi-channel narrowband communication method of the present invention, one-to-one transmission and emission of target signals can be achieved, thereby improving the uniqueness and accuracy of information communication.

[0088] It is worth noting that although the communication frequencies of different narrow-band communication frequency bands are different, making it impossible to achieve signal communication between different narrow-band communication frequency bands, the present invention switches the communication frequency band of the transmitter from a certain narrow-band communication frequency band that has been set to another required narrow-band communication frequency band through channel switching technology, so that the transmitter transmits a signal that matches the other narrow-band communication frequency band, and the receiver can only receive signals that match the narrow-band communication frequency band that it has set, thereby achieving non-interference communication between different narrow-band communication frequency bands. In other words, when communication between different communication frequency bands is required, it is possible to first switch to the set narrow-band communication frequency band, and then load the signal to be transmitted, thereby achieving non-interference communication between different narrow-band communication frequency bands.

[0089] For example, first set it to narrowband communication band A to load the signal to be sent, wait for the transmission to be completed, then switch to the set narrowband communication band B to load the signal to be sent, and wait for the transmission to be completed. By analogy, it is possible to send signals in multiple hopping narrowband communication bands and avoid co-frequency interference.

[0090] It is worth mentioning that in the above embodiments of the present invention, Figure 1 As shown, the step S120 of the multi-channel narrowband communication method comprises the steps of:

[0091] S121: loading and transmitting a first channel signal in a first narrowband communication frequency band that is set in advance; and

[0092] S122: After the first channel signal is transmitted, switch to a second narrowband communication frequency band to load and transmit a second channel signal, wherein the communication frequency of the first narrowband communication frequency band is different from the communication frequency of the second narrowband communication frequency band.

[0093] It is worth noting that the signal can only be transmitted by a transmitter that is pre-set or switched to the matching narrowband communication frequency band; and the signal can only be received by a receiver that is pre-set to the matching narrowband communication frequency band. That is, the first (or second) signal can only be transmitted by a transmitter that is pre-set or switched to the first (or second) narrowband communication frequency band; and the first (or second) signal can only be received by a receiver that is pre-set to the first (or second) narrowband communication frequency band. In other words, when the transmitter is pre-set to the first narrowband communication frequency band, or the transmitter is controlled to switch to the first narrowband communication frequency band, the transmitter can load and transmit the first channel signal; when the receiver is pre-set to the first narrowband communication frequency band, the receiver can receive the first channel signal to ensure interference-free transmission of the signal. That is to say, in this example of the present invention, the receiver will not switch channels. Of course, in other examples of the present invention, when the receiver is not pre-set to the first narrowband communication frequency band, the receiver can also be controlled to switch to the first narrowband communication frequency band to receive the first channel signal.

[0094] Further, in one example of the present invention, Figure 1 As shown, the step S120 may further include the steps of:

[0095] S123: After the second channel signal is transmitted, switch to a third narrowband communication frequency band to load and transmit the third channel signal, wherein the communication frequency of the third narrowband communication frequency band is different from the communication frequencies of the first and second narrowband communication frequency bands.

[0096] That is, in step S110, the number of the narrowband communication frequency bands is at least two and is not limited to a specific number, wherein the communication frequencies of each narrowband communication frequency band are different from each other. Preferably, the communication frequencies of different narrowband communication frequency bands are not adjacent to each other, so as to further reduce the probability of mutual interference between channel signals of different narrowband communication frequency bands.

[0097] It is understandable that in this example of the present invention, after the second channel signal is sent, it will not automatically return to the first narrowband communication band from the second narrowband communication band, but will directly switch from the second narrowband communication band to the third narrowband communication band and wait for the third channel signal to be sent. By analogy, it will not jump back to the first narrowband communication band until all the set narrowband communication bands have been jumped and the signal has been sent. In other words, it will not jump back to the first narrowband communication band until the signals have been sent in multiple narrowband communication bands (i.e., only one channel switching reset is required).

[0098] Of course, in another example of the present invention, the step S120 may further include the steps of: after the second channel signal is sent, first switching from the second narrowband communication frequency band to the first narrowband communication frequency band, then switching from the first narrowband communication frequency band to the set third narrowband communication frequency band, and waiting to send the third channel signal, wherein the communication frequency of the third narrowband communication frequency band is different from the communication frequencies of the first and second narrowband communication frequency bands.

[0099] It is understandable that, in this example of the present invention, after the second channel signal is sent, the second narrowband communication frequency band is first switched back to the first narrowband communication frequency band, and then switched from the first narrowband communication frequency band to the third narrowband communication frequency band, and waits to send the third channel signal. By analogy, each time after sending the second or third channel signal, it is necessary to switch the first narrowband communication frequency band (i.e., multiple channel switching resets are required) until all narrowband communication frequency bands have sent signals.

[0100] In particular, in some embodiments of the present invention, the number of the channel signals under the same narrowband communication frequency band is not limited. Specifically, the first channel signals sent in the step S121 have different coding addresses, so only when the receiver matches the narrowband communication frequency band can receive the first channel signals with different coding addresses, and load the corresponding first channel signals when the corresponding coding address matches the receiver. Therefore, the transmission target of the channel signals with different coding addresses under the same narrowband communication frequency band is unique, so the transmission between the channel signals with different coding addresses will not interfere with each other, thereby improving the reliability of information transmission, while increasing the communication volume of each narrowband communication frequency band, which is beneficial to improving communication efficiency, and is beneficial to group communication and facilitating batch precision control.

[0101] Those skilled in the art should understand that the channel signal is coded information having coded guide information, key, address information, control instruction and verification information, wherein the coded address of the channel signal should be understood as coded information in the coded information that can be recognized by the corresponding receiver and loaded with the control instruction and the verification information, that is, the coded address is a combination of one or more of the guide information, key, and address information in the coded information, and the present invention does not limit this. In other words, different channel signals in the same narrowband communication frequency band are channel signals with different coded addresses, without limiting the control instruction information of the channel signal, and without limiting the coded addresses and control instructions of channel signals in different narrowband communication frequency bands, that is, the coded addresses and / or control instructions of channel signals in different narrowband communication frequency bands can be the same or different, and the present invention does not limit this.

Specifically, Figure 2As shown, the multi-channel narrowband communication system 1 includes at least one first host 11, at least one second host 12, at least one first receiving slave 21 and at least one second receiving slave 22. Each of the first hosts 11 includes a first transmitting host 111, wherein the first transmitting host 111 is configured to have a first narrowband communication frequency band, and is used to be triggered to transmit a first channel signal matching the first narrowband communication frequency band. Each of the second hosts 12 includes a second transmitting host 121, wherein the second transmitting host 121 is configured to have a second narrowband communication frequency band, and is used to be triggered to transmit a second channel signal matching the second narrowband communication frequency band, wherein the communication frequency of the second narrowband communication frequency band is different from the communication frequency of the first narrowband communication frequency band, that is, the frequency band where the first channel signal is located is different from the frequency band where the second channel signal is located. Each of the first receiving slaves 21 is configured to have the first narrowband communication frequency band, and is used to receive the first channel signal matching the first narrowband communication frequency band. Each of the second receiving slaves 22 is configured to have the second narrowband communication frequency band, and is used to receive the second channel signal matching the second narrowband communication frequency band.

[0104] In other words, the first receiving slave 21 can only receive the first channel signal from the first host 11 because it is set to the first narrowband communication frequency band; similarly, the second receiving slave 22 can only receive the second channel signal from the second host 12 because it is set to the second narrowband communication frequency band. In other words, the first receiving slave 21 will not receive the second channel signal from the second host 12, and similarly, the second receiving slave 22 will not receive the first channel signal from the first host 11, thereby avoiding communication conflicts or co-frequency interference between the host and the slave, and realizing high-speed interference-free communication in the same narrowband communication frequency band.

[0105] It is worth noting that a certain communication frequency band is divided into at least two narrowband communication frequency bands (such as the first narrowband communication frequency band and the second narrowband communication frequency band), and the communication frequencies of each narrowband communication frequency band are different from each other, so that the communication frequency of the first narrowband communication frequency band is different from the communication frequency of the second narrowband communication frequency band, that is, the communication frequency range of the first narrowband communication frequency band and the communication frequency range of the second narrowband communication frequency band are neither overlapped nor crossed, so as to minimize the mutual interference or influence between the first channel signal and the second channel signal during transmission. For example, the communication frequency of the first narrowband communication frequency band can be greater than or equal to 863MHZ and less than 863.1875MHZ; the communication frequency of the second narrowband communication frequency band can be greater than or equal to 863.1875MHZ and less than 863.375MHZ.

[0106] It is worth mentioning that in this embodiment of the present invention, Figure 2 As shown, the multi-channel narrowband communication system 1 may further include at least one third host 13 and at least one third receiving slave 23. Each of the third hosts 13 includes a third transmitting host 131, wherein the third transmitting host 131 is configured to have a third narrowband communication frequency band, and is used to be triggered to transmit a third channel signal matching the third narrowband communication frequency band, wherein the communication frequency of the third narrowband communication frequency band is different from the communication frequency of the first and second narrowband communication frequency bands. Each of the third receiving slaves 23 is configured to have the third narrowband communication frequency band, and is used to receive the third channel signal matching the third narrowband communication frequency band, so as to communicate without interference between the host and the slave having the same narrowband communication frequency band, and effectively avoid communication conflicts or communication interferences between the host and the slave having different narrowband communication frequency bands.

[0107] It is worth noting that in the above-mentioned embodiment of the present invention, although the advantages and characteristics of the multi-channel narrowband communication system 1 of the present invention are described by taking the three narrowband communication frequency bands of the first narrowband communication frequency band, the second narrowband communication frequency band and the third narrowband communication frequency band as examples, the multi-channel narrowband communication system 1 is not limited to these three narrowband communication frequency bands. In other examples of the present invention, the multi-channel narrowband communication system 1 may also have a fourth, fifth, and sixth narrowband communication frequency bands, that is, the multi-channel narrowband communication system 1 may include more than three narrowband communication frequency bands. In addition, the communication frequencies of the first narrowband communication frequency band, the second narrowband communication frequency band and the third narrowband communication frequency band may be continuous or intermittent, and the present invention does not impose further restrictions on this.

[0108] Furthermore, if Figure 2As shown, in the multi-channel narrowband communication system 1 of this embodiment of the present invention, the first host 11 may also include a first receiving host 112, wherein the first receiving host 112 is configured to have the first narrowband communication frequency band, for receiving the first channel signal with the first narrowband communication frequency band; the second host 12 may also include a second receiving host 122, wherein the second receiving host 122 is configured to have the second narrowband communication frequency band, for receiving the second channel signal with the second narrowband communication frequency band; the third host 13 may also include a third receiving host 132, wherein the third receiving host 132 is configured to have the third narrowband communication frequency band, for receiving the third channel signal with the third narrowband communication frequency band. In this way, when the first transmitting host 111 of a certain first host 11 (or the second transmitting host 121 of the second host 12, or the third transmitting host 131 of the third host 13) is triggered to transmit the first channel signal (or the second channel signal, or the third channel signal), the first receiving host 112 of another first host 11 (or the second receiving host 122 of the second host 12, or the third receiving host 132 of the third host 13) can also receive the first channel signal (or the second channel signal, or the third channel signal) to achieve interference-free communication between hosts having the same narrowband communication channel.

[0109] It is worth noting that the multi-channel narrowband communication system 1 of the present invention can be applied to technical fields such as lighting, security, etc., to ensure self-management and energy saving of lighting systems or alarm systems. Taking the lighting system as an example, the first, second and third hosts 11, 12, 13 of the multi-channel narrowband communication system 1 are suitable for being communicatively connected to the main induction lamps of the lighting system, and the first, second and third receiving slaves 21, 22, 23 of the multi-channel narrowband communication system 1 are suitable for being communicatively connected to the slave induction lamps of the lighting system. The main induction lamp of the lighting system can actively sense the moving objects or people around, so that when the moving objects or people are sensed around, the main induction lamp is automatically adjusted, such as being lit and / or dimmed, and triggers the transmitting hosts of the first, second and third hosts 11, 12, 13 to transmit corresponding signals. Although the slave induction lamps of the lighting system cannot actively sense the moving objects or people around them, when the first, second and third receiving slave machines 21, 22, 23 receive corresponding signals, the slave induction lamps of the lighting system will automatically light up in response to the signals received by the receiving slave machines, thereby realizing the automatic management function of the lighting system.

[0110] It is understandable that the master induction lamp of the lighting system can be implemented as a lamp equipped with a microwave detector, but is not limited to, so as to sense the moving objects or people around through the microwave detector; while the slave induction lamp of the lighting system is implemented as a lamp not equipped with a microwave detector, so as to reduce the cost of the entire lighting system. Of course, in other examples of the present invention, the master induction lamp of the lighting system can also be implemented as a lamp equipped with a sensing device such as an infrared detector, a sound detector, an image detector, etc.

[0111] For example, Figure 3A and 3B As shown, the first application scenario of the multi-channel narrowband communication system according to the above embodiment of the present invention is illustrated, which shows the application of the multi-channel narrowband communication system in broadcast mode, that is, the multi-channel narrowband communication system needs to perform broadcast operation and only communicate without interference within the same narrowband communication frequency band.

[0112] Specifically, Figure 3A As shown, the first application scenario takes the application scenario of three-story corridor lighting as an example. The main induction lamp 31 is set at the entrance and exit (or door) of each floor corridor to sense people or moving objects entering and exiting the entrance and exit, and the slave induction lamp 32 is set at other positions (i.e., non-entrance and exit positions) of each floor corridor. The first host 11 communicatively connected to the main induction lamp 31 is set in the first floor corridor (such as the first host 11 is set at the main induction lamp 31 in the first floor corridor); and the first receiving slave 21 communicatively connected to the slave induction lamp 32 is set in the first floor corridor (such as the first receiving slave 21 is set at the slave induction lamp 32 in the first floor corridor). The second host 12 is set at all the main induction lamps 31 in the second floor corridor; and the second receiving slave 22 is set at all the slave induction lamps 32 in the second floor corridor. The third host 13 is disposed at all the master induction lamps 31 in the corridor on the third floor; and the third receiving slave 23 is disposed at all the slave induction lamps 32 in the corridor on the third floor.

[0113] In this way, Figure 3BAs shown, when a certain master induction lamp 31 in the corridor of the first floor senses a moving person or object, the master induction lamp 31 is lit, and the first transmitting host 111 of the first host 11 located at the master induction lamp 31 is triggered to transmit the first channel signal. Then, the first receiving slave 21 and the first receiving host 112 in the corridor of the first floor receive the first channel signal because they have the first narrowband communication frequency band, so that all the slave induction lamps 32 and other master induction lamps 31 in the corridor of the first floor are lit in response to the first channel signal. At the same time, the second and third receiving slaves 22, 23 and the second and third receiving hosts 112, 113 in the corridors of the second and third floors cannot receive the first channel signal because they have the second and third narrowband communication frequency bands, so that all the slave induction lamps 32 and other master induction lamps 31 in the corridors of the second and third floors will not be lit, so as to avoid the lamps in the corridors of the second and third floors from being disturbed by the communication in the corridor of the first floor, which helps to achieve the purpose of automatic management of the lighting system and energy saving. In other words, the host and slave in each corridor transmit signals in the same narrowband communication frequency band, and the host and slave in corridors of different floors transmit signals in different narrowband communication frequency bands, so as to avoid communication interference between the host and slave in corridors of different floors, thereby realizing broadcast control of the lighting system in the corridors of the same floor. It is understandable that when the main induction lamp 31 senses a moving person or object, the first reflection host 111 can transmit the first channel signal after the main induction lamp 31 is lit, or the first reflection host 111 can also transmit the first channel signal before the main induction lamp 31 is lit, and the present invention will not elaborate on this.

[0114] It is worth mentioning that, in the multi-channel narrowband communication system 1 according to this embodiment of the present invention, the first transmitting host 111 of the first host 11 can also be controlled to switch to the second narrowband communication frequency band, for transmitting a second channel signal matching the second narrowband communication frequency band, so that the second receiving host 122 of the second host 12 can receive the second channel signal from the first host 11, so as to realize interference-free communication between the first host 11 and the second host 12, that is, to realize interference-free communication between hosts with different narrowband communication frequency bands. In other words, when a main induction lamp 31 of the lighting system is lit up due to sensing a moving person or object, the first transmitting host 111 of the first host 11 connected to the main induction lamp 31 first transmits a first channel signal to be received by the first receiving slave 21, so that the slave induction lamp 32 connected to the first receiving slave 21 is lit up; and after transmitting the first channel signal, the first transmitting host 111 switches to the second narrowband communication frequency band and transmits the second channel signal to be received by the second receiving host 122, so that the main induction lamp 31 connected to the second receiving host 122 is lit up.

[0115] Similarly, the second transmitting host 121 of the second host 12 can be controlled to switch to the third narrowband communication frequency band, for transmitting a third channel signal matching the third narrowband communication frequency band, so that the third receiving host 132 of the third host 13 can receive the third channel signal from the second host 12; or the third transmitting host 131 of the third host 13 can be controlled to switch to the second narrowband communication frequency band, for transmitting a second channel signal matching the second narrowband communication frequency band, so that the second receiving host 122 of the second host 12 can receive the second channel signal from the third host 13, thereby realizing interference-free communication between hosts with different narrowband communication frequency bands.

[0116] For example, Figure 4A and Figure 4B As shown, a second application scenario of the multi-channel narrowband communication system according to the above embodiment of the present invention is illustrated, which shows the application of the multi-channel narrowband communication system in a channel switching mode, that is, the multi-channel narrowband communication system needs to perform a channel switching operation to communicate without interference in different narrowband communication frequency bands.

[0117] Specifically, Figure 4AAs shown, the second application scenario takes the application scenario of stairwell lighting as an example, and each stairwell is provided with the main induction lamp 31 for sensing people walking or moving objects in the stairwell. A first host 11 communicatively connected to the main induction lamp 31 is provided in the first stairwell; a second host 12 communicatively connected to the main induction lamp 31 is provided in the second stairwell; and a third host 13 communicatively connected to the main induction lamp 31 is provided in the third stairwell.

[0118] In this way, Figure 4B As shown, when a person walks to the stairwell on the first floor, the main induction lamp 31 located in the stairwell on the first floor senses the walking person and is lit up, and the first transmitting host 111 of the first host 11 is controlled to switch to the second narrowband communication frequency band to transmit the second channel signal; then the second receiving host 122 of the second host 12 located in the stairwell on the second floor will receive the second channel signal, so that the main induction lamp 31 located in the stairwell on the second floor is lit up, thereby achieving that when a person walks in the stairwell on the first floor, the lamps located in the stairwell on the second floor are lit in advance, so as to provide lighting for the person in advance. By analogy, when a person walks to the stairwell on the second floor and the main induction lamp 31 located in the stairwell on the second floor senses the walking person, the second transmitting host 121 of the second host 12 is controlled to switch to the third narrowband communication frequency band to transmit the third channel signal; then the third receiving host 132 of the third host 13 located in the stairwell on the third floor will receive the third channel signal, so that the main induction lamp 31 located in the stairwell on the third floor will be lit in advance to provide intelligent lighting services.

[0119] It is worth noting that when the main induction lamp 31 located in the stairwell of the second floor senses a person walking, it cannot be determined whether the person is going upstairs or downstairs. Therefore, in this example of the present invention, the second transmitting host 121 of the second host 12 can also be controlled to switch to the first narrowband communication frequency band to transmit the first channel signal, so that the first receiving host 112 of the first host 11 located in the stairwell of the first floor receives the first channel signal to light up the lamps located in the stairwell of the first floor in advance. In other words, the second transmitting host 121 of the second host 12 can first switch to the third narrowband communication frequency band to transmit the third channel signal, and then switch to the first narrowband communication frequency band to transmit the first channel signal, so that the second host 12 can communicate with the third host 13 and the first host 11 respectively without interference.

[0120] It can be understood that the main induction lamp 31 of the lighting system of the present invention can operate in low brightness mode and high brightness mode. When the main induction lamp 31 operates in low brightness mode, the brightness of the light emitted by the main induction lamp 31 is lower to consume less electric energy; and when the main induction lamp 32 operates in high brightness mode, the brightness of the light emitted by the main induction lamp 31 is higher to consume more electric energy.

[0121] Of course, in other examples of the present invention, the low brightness mode of the main induction lamp 31 means that when receiving another channel signal, it will enter a low brightness state to achieve the effect of early lighting. The high brightness mode of the main induction lamp 31 means that when receiving another channel signal, it will enter a high brightness state to improve the lighting effect.

[0122] Preferably, when the main induction lamp 31 senses a moving person or object, regardless of whether the receiving host connected to the main induction lamp 31 receives a channel signal, the main induction lamp 31 will be lit to work in a high-brightness mode to provide better lighting conditions; and when the main induction lamp 31 does not sense a moving person or object, if the receiving host connected to the main induction lamp 31 receives a corresponding channel signal, the main induction lamp 31 will be lit to work in a low-brightness mode to save resources; if the receiving host connected to the main induction lamp 31 does not receive the corresponding channel signal, the main induction lamp 31 will not be lit.

[0123] More preferably, the master induction lamp 31 and the slave induction lamp 32 of the lighting system can be automatically turned off after being lit for a period of time (such as 1 minute, etc.) to save energy. Even in some examples of the present invention, the master induction lamp 31 of the lighting system is lit to work in high brightness mode for a period of time (such as 30 seconds, etc.), and then continue to work in low brightness mode for a period of time (such as 30 seconds, etc.) before turning off, so as to find a reasonable balance between providing better lighting conditions and saving resources.

[0124] According to the above-mentioned embodiment of the present invention, the first transmitting host 111 of the first host 11 of the multi-channel narrowband communication system 1 is not only triggered to transmit the first channel signal first, and then switched to the second narrowband communication frequency band to transmit the second channel signal, but also can switch to the third narrowband communication frequency band to transmit the third channel signal after transmitting the second channel signal, so that the second receiving host 122 of the second host 12 and the third receiving host 132 of the third host 13 can respectively receive the second channel signal and the third channel signal from the first host 11, so as to perform interference-free communication between the first host 11 and the second host 12 and the third host 13. Similarly, the second transmitting host 121 of the second host 12 can also switch to the first narrowband communication frequency band to transmit the first channel signal, and switch to the third narrowband communication frequency band to transmit the third channel signal; the third transmitting host 131 of the third host 13 can also switch to the first narrowband communication frequency band to transmit the first channel signal, and switch to the second narrowband communication frequency band to transmit the second channel signal, thereby realizing interference-free communication between multiple hosts with different narrowband communication frequency bands.

[0125] It is worth noting that, in this example of the present invention, the first receiving slave 21 can receive the first channel signal because it has the first narrowband communication frequency band, but the slave induction lamp 32 connected to the first receiving slave 21 will not respond to the first channel signal, that is, the slave induction lamp 32 will not be lit up because the first receiving slave 21 receives the first channel signal. In other words, the slave induction lamp 32 connected to the first receiving slave 21 will only be lit up in response to the first channel signal, and will not be lit up in response to the first channel signal, so as to prevent the slave induction lamp 32 from being accidentally or unintentionally lit, which helps to save energy. Similarly, although the second and third receiving slaves 22 and 23 can receive the second and third channel signals respectively, the slave induction lamp 32 connected to the second and third receiving slaves 22 and 23 will not be lit up in response to the second and third channel signals.

[0126] Of course, in other examples of the present invention, the slave induction lamps 32 connected to the first, second and third receiving slaves 21, 22, 23 will not only be illuminated in response to the first, second and third channel signals, but will also be illuminated in response to the first, second and third channel signals, so as to achieve interference-free communication between the host and slaves having different narrowband communication bands.

[0127] For example, Figure 5A and Figure 5BAs shown, a third application scenario of the multi-channel narrowband communication system according to the above embodiment of the present invention is illustrated, which shows the application of the multi-channel narrowband communication system in a hybrid mode, that is, the multi-channel narrowband communication system requires both broadcast operation and channel switching operation to communicate without interference in the same and different narrowband communication frequency bands.

[0128] Specifically, Figure 5A As shown, the third application scenario takes the application scenario of underground parking lot lighting as an example, wherein the underground parking lot is divided into area A, area B and area C, and area A, area B and area C are arranged in a T-shape. Area A, area B and area C are all provided with the master induction lamp 31 and the slave induction lamp 32, and Figure 5A In area A, the host communicably connected to the master induction lamp 31 is the first host 11, and the slave communicably connected to the slave induction lamp 32 is the first receiving slave 21; in area B, the host communicably connected to the master induction lamp 31 is the second host 12, and the slave communicably connected to the slave induction lamp 32 is the second receiving slave 22; in area C, the host communicably connected to the master induction lamp 31 is the third host 13, and the slave communicably connected to the slave induction lamp 32 is the third receiving slave 23.

[0129] In this way, Figure 5BAs shown, when the master induction lamp 31 located in area A senses a vehicle or a person moving in area A to be lit, the first transmitting host 111 of the first host 11 connected to the master induction lamp 31 in area A will be triggered to transmit the first channel signal, so that the first receiving host 112 and the first receiving slave 21 of the other first host 11 can receive the first channel signal to light up the other master induction lamps 31 connected to the first host 111 and the slave induction lamps 32 connected to the first receiving slave 21, that is, the master induction lamp 31 and the slave induction lamp 32 located in area A are all lit. Then, after transmitting the first channel signal, the first transmitting host 111 of the first host 11 is controlled to switch to the second narrowband communication frequency band and transmit the second channel signal, so that the second receiving host 122 of the second host 12 receives the second channel signal to light up the master induction lamp 31 connected to the second host 12, that is, the master induction lamp 31 located in area B is lit. Finally, after transmitting the second channel signal, the first transmitting host 111 of the first host 11 is controlled to switch to the third narrowband communication frequency band and transmit the third channel signal, so that the third receiving host 132 of the third host 13 receives the third channel signal to light up the master induction lamp 31 connected to the third host 13, that is, the master induction lamp 31 located in the C area is lit. It is worth noting that although the second receiving slave 22 and the third receiving slave 23 can receive the second channel signal and the third channel signal respectively, the slave induction lamp 32 located in the B area will not be lit in response to the second channel signal, and the slave induction lamp 32 located in the C area will not be lit in response to the third channel signal, so as to achieve the purpose of saving resources.

[0130] Similarly, when the master induction lamp 31 located in area B senses a vehicle or a person moving to area B and is lit, the second transmitting host 121 of the second host 12 connected to the master induction lamp 31 in area B will be triggered to transmit the second channel signal, so that the second receiving host 122 and the second receiving slave 22 of the other second host 12 can receive the second channel signal to light up the other master induction lamps 31 connected to the second host 121 and the slave induction lamps 32 connected to the second receiving slave 22, that is, the master induction lamp 31 and the slave induction lamp 32 located in area B are all lit. Then, after transmitting the second channel signal, the second transmitting host 121 of the second host 12 is controlled to switch to the third narrowband communication frequency band and transmit the third channel signal, so that the third receiving host 132 of the third host 13 receives the third channel signal to light up the master induction lamp 31 connected to the third host 13, that is, the master induction lamp 31 located in area C is lit. Finally, after transmitting the third channel signal, the second transmitting host 121 of the second host 12 is controlled to switch to the first narrowband communication frequency band and transmit the first channel signal, so that the first receiving host 112 of the first host 11 receives the first channel signal to light up the main induction lamp 31 connected to the first host 11, that is, the main induction lamp 31 located in the A area is lit.

[0131] It is worth noting that when the main induction lamp 31 located in area A senses a moving person or a moving vehicle, it cannot be determined whether the person or the vehicle moves to area B or area C. Therefore, in this example of the present invention, the first transmitting host 111 of the first host 11 can be controlled to switch to the second narrowband communication frequency band to transmit the second channel signal, so that the second receiving host 122 of the second host 12 located in area B receives the second channel signal to light up the main induction lamp 31 located in area B in advance; but the second receiving slave 22 located in area B will receive the second channel signal, but will not light up the slave induction lamp 32 located in area B, so as to prevent the slave induction lamp 32 from being lit in advance or lit uselessly and wasting energy. Similarly, the first transmitting host 111 of the first host 11 can also be controlled to switch to the third narrowband communication frequency band to transmit the third channel signal, so that the third receiving host 132 of the third host 13 located in the C area receives the third channel signal to light up the main induction lamp 31 located in the C area in advance; but the third receiving slave 23 located in the C area will receive the third channel signal, but will not light up the slave induction lamp 32 located in the C area, so as to prevent the slave induction lamp 32 from being lit in advance or lit uselessly and wasting energy.

[0132] For example, 6A to 6F As shown, the fourth application scenario of the multi-channel narrowband communication system according to the above embodiment of the present invention is explained. Fig. 6A and Figure 6B As shown, the first case of the fourth application scenario of the multi-channel narrowband communication system is shown, wherein the fourth application scenario takes the application scenario of highway lighting as an example, and multiple main induction lamps 31, 31', 31" are arranged on both sides of the highway for sensing people or vehicles walking on the highway. It is worth mentioning that the highway is also provided with the first host 11 respectively communicatively connected to the main induction lamps 31, 31', and the second host 12 respectively communicatively connected to the main induction lamps 31', 31".

[0133] Specifically, the main induction lamp 31 communicates with the main induction lamp 31' through the first narrowband communication frequency band, and the main induction lamp 31' communicates with the main induction lamp 31" through the second narrowband communication frequency band. Specifically, when a car or a person walks into the lighting area of ​​the main induction lamp 31, the main induction lamp 31 senses the movement of the car or the person and is lit, and the first transmitting host 111 of the first host 11 is triggered to send the first channel signal, and the first receiving host 112 of the first host 11 receives the first channel signal and lights up the main induction lamp 31' in advance. When the car or the person further walks into the lighting area of ​​the main induction lamp 31', the second transmitting host 121 of the second host 12 is triggered to send the second channel signal, and the second receiving host 122 of the second host 12 receives the second channel signal and lights up the main induction lamp 31" in advance. It can be understood that the first channel signal cannot communicate in the second narrowband communication frequency band, and the second channel signal cannot communicate in the first narrowband communication frequency band, that is, the first narrowband communication frequency band can only be used for sending and receiving the first channel signal, and the second narrowband communication frequency band can only be used for sending and receiving the second channel signal, so the communication between the first narrowband communication frequency band and the second narrowband communication frequency band does not interfere with each other. In other words, each narrowband communication frequency band represents the transmission of signals with different communication frequencies, and the communication of signals with different communication frequencies is unique, so that the speed of data transmission can be increased while improving the accuracy of data transmission.

[0134] It can be understood that Fig. 6A and Figure 6B The point-to-point communication mode of the multi-channel narrowband communication system is shown. In this embodiment, the main induction lamp 31 transmits a signal to the main induction lamp 31' through the first narrowband communication frequency band, and the main induction lamp 31' transmits a signal to the main induction lamp 31" through the second narrowband communication frequency band. In some embodiments of the present invention, the main induction lamp 31" can also be configured to transmit a signal to the main induction lamp 31' through the first narrowband communication frequency band, and correspondingly, the main induction lamp 31' transmits a signal to the main induction lamp 31 through the second narrowband communication frequency band. In some embodiments of the present invention, the main induction lamp 31 can also communicate with the main induction lamps 31', 31" respectively through the first narrowband communication frequency band and the second narrowband communication frequency band, that is, the main induction lamps 31, 31', 31" can be configured to communicate at different communication frequencies, and the present invention is not limited to this.

[0135] like Figure 6C and Fig.6D As shown, the second situation of the multi-channel narrowband communication system in the fourth application scenario is explained. Specifically, the highway is provided with the first host 11 communicably connected to the main induction lamps 31, 31' respectively and the second host 12 communicably connected to the main induction lamps 31', 31" respectively, that is, the main induction lamp 31 and the main induction lamp 31' are arranged to communicate through the first narrowband communication frequency band, and the main induction lamp 31' and the main induction lamp 31" are arranged to communicate through the second narrowband communication frequency band.

[0136] Specifically, when the main induction lamp 31' senses the movement of a car or a person, the main induction lamp 31' is controlled to light up, and the first transmitting host 111 of the first host 11 and the second transmitting host 121 of the second host 12 of the main induction lamp 31' are triggered simultaneously. Specifically, the first transmitting host 111 of the first host 11 sends the first channel signal to the first receiving host 112, thereby lighting up the main induction lamp 31 in advance; the second transmitting host 121 of the second host 12 sends the second channel signal to the second receiving host 122, thereby lighting up the main induction lamp 31" in advance. Therefore, it can be understood that the main induction lamp 31' communicates with the main induction lamp 31 and the main induction lamp 31" through the first narrowband communication frequency band and the second narrowband communication frequency band respectively, so that the communication between the main induction lamp 31' and the main induction lamp 31 and the main induction lamp 31" does not interfere with each other.

[0137] It is worth mentioning that the communication between the main induction lamp 31' and the main induction lamp 31" can also be carried out through the control mode. Specifically, when the main induction lamp 31' is lit and triggers the first transmitting host 111, the first transmitting host 111 first sends the first channel signal to the first receiving host 112 to light up the main induction lamp 31 in advance, and then the first transmitting host 111 is switched to the second narrowband communication frequency band to transmit the second channel signal, and the second receiving host 122 of the second host 12 receives the second channel signal and lights up the induction lamp 31" in advance. It can be understood that in this communication mode, although the second receiving host 122 receives the second channel signal sent by the first transmitting host 111, the second receiving host 122 still receives the signal transmitted by the second narrowband communication frequency band, that is, the main induction lamp 31' still communicates with the main induction lamp 31 and the main induction lamp 31" through the first narrowband communication frequency band and the second narrowband communication frequency band respectively without interfering with each other.

[0138] That is to say, the multi-channel narrowband communication method can realize switching between different narrowband communication frequency bands and select different narrowband communication frequency bands for communication, which is conducive to expanding the application scope of the multi-channel narrowband communication method and improving communication efficiency. It can be understood that the switching order of the first transmitting host 111 between different narrowband communication frequency bands can be set to facilitate the realization of control with clear directionality, such as point-to-point one-transmit-one-receive control, point forward control and point backward control, and the present invention is not limited to this.

[0139] It can also be understood that even if the second host 12 does not have the second transmitting host 121, the main induction lamp 31' can still communicate with the main induction lamp 31" in a controlled manner through the second narrowband communication frequency band.

[0140] In addition, it is worth mentioning that in the second case, the main induction lamps 31, 31" on both sides of the main induction lamp 31' can be lit in advance, so in practical applications, it is not necessary to judge the moving direction of the car or person to light the lamps in advance for practical use.

[0141] like Fig. 6E and Fig. 6F As shown, the multi-channel narrowband communication system is illustrated in the third case of the fourth application scenario, which shows an application mode of the multi-channel narrowband communication system combined with the coded address. Specifically, the highway is provided with the first host 11 communicatively connected to the main induction lamps 31, 31', 31", respectively, wherein the first host 11 includes a first transmitting host 111 and two first receiving hosts 112.

[0142] Specifically, when the main induction lamp 31' senses the movement of a car or a person, the main induction lamp 31' is controlled to light up and trigger the first transmitting host 111 of the first host 11, wherein the first transmitting host 111 sends the first channel signal assigned with the first address and the first channel signal assigned with the second address to the two first receiving hosts 112, thereby respectively lighting up the main induction lamp 31 and the main induction lamp 31" in advance.

[0143] It can be understood that, since the first channel signals respectively sent by the first transmitting host 111 have different coding addresses, only the first receiver 112 that matches the coding address can receive the first channel signal with the coding address. Therefore, the transmission target of the first channel signals with different coding addresses is unique, and thus the transmission between the first channel signals with different coding addresses will not interfere with each other, thereby improving the reliability of information transmission, and at the same time increasing the communication volume of each narrowband communication band, which is beneficial to improving communication efficiency, and is beneficial to packet communication and easy to achieve batch precision control.

[0144] It is worth mentioning that in some embodiments of the present invention, the first host 11 may also include multiple first receiving hosts 112. Correspondingly, the first transmitting host 111 can respectively transmit multiple first channel signals assigned with different coding addresses to the corresponding first receiving hosts 112 to respectively control the early lighting of multiple main induction lamps. Therefore, the present invention does not limit the number of the first receiving hosts 112.

[0145] In particular, in some embodiments of the present invention, the first transmitter 111 of the first host 11 can simultaneously provide two or more narrowband communication bands, which is conducive to packet communication and facilitates batch precision control, and is also conducive to multi-directional control, such as one-transmit-multiple-receive control from point to point.

[0146] In addition, it is worth mentioning that in some embodiments of the present invention, the first host 11 may also include multiple first transmitting hosts 111, wherein each first transmitting host 111 corresponds to each first receiving host 112, so that when the first host 11 is triggered, each first transmitting host 111 sends the corresponding first channel signal to the first receiving host 112 adapted thereto to respectively light up the corresponding main induction lamp in advance. It can also be understood that the first host 11 can simultaneously light up multiple main induction lamps in advance through multiple first transmitting hosts 111 and multiple first receiving hosts 112, so the present invention does not limit the number of the first transmitting hosts 111.

[0147] It can be understood that in the fourth application scenario of the multi-channel narrowband communication system, the multi-channel narrowband communication system has multiple modes and directions of information transmission. For example, in some embodiments of the present invention, the first host 11 may also include multiple first receiving hosts 112, wherein the multiple first receiving hosts 112 respectively correspond to the first transmitting host 111, so as to achieve one-transmit-multiple-receive control by receiving the same channel signal by multiple receiving hosts 112; for example, in some embodiments of the present invention, the same receiving host 112 is configured to have multiple narrowband communication frequency bands, so as to achieve multiple-transmit-one-receive control by receiving different channel signals transmitted by multiple transmitting hosts 111 by the receiving host 112, and the present invention does not limit this.

[0148] Schematic lighting equipment

[0149] According to another aspect of the present invention, Fig. 7A and 7B As shown, an embodiment of the present invention further provides a lighting device, which is configured with a master or slave of the multi-channel narrowband communication system according to the present invention, so as to perform interference-free communication through the multi-channel narrowband communication system, thereby realizing self-management of the lighting device.

[0150] For example, Fig. 7A As shown, the lighting device 40A is implemented as a main induction lamp, including a lamp body 41A, a sensing device 42A and a host 10, wherein the sensing device 42A and the host 10 are both arranged on the lamp body 41A, and the sensing device 42A is communicatively connected to the host 10 and the lamp body 41A respectively. The lamp body 41A is used for emitting light. The sensing device 42A is used to sense a person or object moving around the lamp body 41A, and when sensing a moving person or object, sends an action command signal to the lamp body 41A and the host 10. The lamp body 41A is used to respond to the action command signal from the sensing device 42A and be lit for lighting. The host 10 includes a transmitting host 101, wherein the transmitting host 101 is configured to have a preset narrowband communication frequency band, and is used to respond to the action command signal from the sensing device 42A and be triggered to transmit a signal matching the preset narrowband communication frequency band. It can be understood that the preset narrowband communication frequency band can be implemented as the first narrowband communication frequency band, so that the host 10 is implemented as the first host 11; or the preset narrowband communication frequency band can be implemented as the second narrowband communication frequency band, so that the host 10 is implemented as the second host 12; or alternatively, the preset narrowband communication frequency band can be implemented as the third narrowband communication frequency band, so that the host 10 is implemented as the third host 13.

[0151] Furthermore, the host 10 of the lighting device 40A may also include a receiving host 102, wherein the receiving host 102 is configured to have the preset narrowband communication frequency band, and is used to receive the signal matching the preset narrowband communication frequency band from other lighting devices 40A, so that the lamp body 41A of the lighting device 40A responds to the signal matching the preset narrowband communication frequency band and is illuminated for lighting.

[0152] Preferably, after the transmitting host 101 of the host 10 of the lighting device 40A sends a signal matching the preset narrowband communication frequency band, the transmitting host 101 can also be controlled to switch to another different preset narrowband communication frequency band, for transmitting a channel signal matching the other preset narrowband communication frequency band; wherein the receiving host 102 can also receive the channel signal having the same preset narrowband communication frequency band, so that the lamp body 41A of the lighting device 40A responds to the channel signal and is lit for illumination. In other words, the transmitting host 101 includes a transmitter and a control module, wherein the control module is used to control the control of the transmitter so that the transmitter switches to a preset narrowband communication frequency band; wherein the transmitter is used to transmit a signal matching the preset narrowband communication frequency band. It is understandable that when the preset narrowband communication frequency band is the first narrowband communication frequency band, the other different preset narrowband communication frequency band can be implemented as the second narrowband communication frequency band or the third narrowband communication frequency band or other different narrowband communication frequency bands, so as to achieve interference-free communication between different narrowband communication frequency bands.

[0153] For example, Figure 7B As shown, the lighting device 40B is implemented as a slave induction lamp, including a lamp body 41B and a slave 20, wherein the slave 20 is arranged in the lamp body 41B, and the slave 20 is communicatively connected to the lamp body 41B. The slave 20 is configured to have a preset narrowband communication frequency band for receiving a signal matching the preset narrowband communication frequency band. The lamp body 41B is used to be lit up for lighting in response to the signal received via the slave 20. It can be understood that the preset narrowband communication frequency band can be implemented as the first narrowband communication frequency band, so that the slave 20 is implemented as the first receiving slave 21; or the preset narrowband communication frequency band can be implemented as the second narrowband communication frequency band, so that the slave 20 is implemented as the second receiving slave 22; or, the preset narrowband communication frequency band can be implemented as the third narrowband communication frequency band, so that the slave 20 is implemented as the third receiving slave 23.

[0154] It is worth noting that in this example of the present invention, although the slave 20 of the lighting device 40A can receive the corresponding channel signal, the lamp body 41B will not be illuminated in response to the channel signal, that is, the lamp body 41B will not be illuminated due to the slave 20 receiving the channel signal, which helps to achieve automatic control. Of course, in other examples of the present invention, when the slave 20 of the lighting device 40A receives the corresponding channel signal, the lamp body 41B can be illuminated in response to the channel signal, that is, the lamp body 41B can be illuminated due to the slave 20 receiving the channel signal, to meet specific application scenarios.

[0155] It is worth mentioning that those skilled in the art should understand that lighting up the lamp body is not limited to the regulation process of receiving the corresponding channel signal in the light-off state to the full-bright state, but can also be understood as the regulation process of receiving the corresponding channel signal in the light-off state to the low-brightness / half-brightness state, or receiving the corresponding channel signal in the low-brightness / half-brightness state to the full-brightness state, and the present invention is not limited to this.

[0156] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
