Technical Field

The utility model relates to the field of communication technology, especially, relate to a multichannel narrow-band communication device and lighting apparatus.

Background

The conventional communication technology generally has the problem of co-frequency interference, that is, when communication is performed on the same frequency band channel (channel) and signals are transmitted simultaneously, a receiver often causes the received signals to be interfered, or causes communication data to be blocked/queued, or even causes no signal to be received. The principle of this interference is mainly: when the receiver is receiving decoded data and another transmitter is transmitting data at the same frequency, the accuracy of the data reception at the receiver is disturbed/affected. For example, there are two transmitters a and B and one receiver C, and when the transmitters a and B use the same frequency band and transmit wireless information at the same time, the receiver C cannot receive the information transmitted by the transmitters a and B or causes information error due to reception interference. In order to solve such problems, some manufacturers currently adopt a coordinator solution, i.e., a coordinator is used to allocate timing transmission or reception, which results in a significant increase in cost.

Another solution in the market is to distinguish information of the same communication frequency band by means of coding addresses, and then load data information to be communicated, so as to realize marking and identification of the data information. However, the communication speed of this solution is relatively slow, mainly because when multiple devices communicate, the communication data may be blocked/queued, and the receiver may be interfered or may not receive any signal.

In addition, the information of the same communication frequency band is distinguished in an address coding mode, and the receiving address mark is easy to change or fail along with the time, so that the signal cannot be received or the equipment loses contact.

Illustrative method

As shown in fig. 1, a communication method of a multi-channel narrow-band communication device according to an embodiment of the present invention is illustrated for solving the problem of data congestion or data unreceivable in the current communication method, that is, solving the problem of co-channel communication interference in the current communication method. Specifically, as shown in fig. 1, the communication method of the multi-channel narrow-band communication device includes the steps of:

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

and receiving the first channel signal corresponding to the narrow-band communication frequency band of the first channel signal, so as to distinguish different target information in the same communication frequency band by different narrow-band communication frequency bands without a coordinator.

Further, the communication method of the multi-channel narrow-band communication device comprises the steps of:

s110: dividing a communication frequency band into at least two narrow frequency communication frequency bands, wherein the communication frequencies of the narrow frequency communication frequency bands are different from each other, so that signals can be communicated without interference in the same narrow frequency communication frequency band; and

s120: and switching one narrow-band communication frequency band to another narrow-band communication frequency band by a frequency hopping technology so as to enable signals to be communicated among different narrow-band communication frequency bands without interference.

Illustratively, taking 868MHZ band (i.e. band width of 863-: the allowed frequency bandwidth is 6M, and is divided into 32 narrow-band communication bands, so that the allowed frequency bandwidth for transmitting and receiving each narrow-band communication band (i.e. channel) is 6/32-0.1875 MHZ. Because the communication frequency of each narrow-band communication frequency band is different (i.e. the communication frequency ranges of the different narrow-band communication frequency bands are not crossed or overlapped), the communication frequency ranges are not interfered with each other when signals are sent in the different narrow-band communication frequency bands simultaneously. Therefore, each narrow-band communication frequency band has a preset communication frequency band, which is equivalent to establishing a plurality of different high-speed channels, and the problems of communication conflict or same-frequency interference do not exist. In addition, the communication technology of the narrow-band communication frequency band can also reduce the interference to other equipment, thereby achieving the purpose of mutual noninterference. It is understood that the communication frequency range of the communication band can also be defined as a low-rate wireless personal area network LR-WPSN such as 915MHZ (i.e. bandwidth of 896-.

It can be understood that only signals with the same communication frequency as the narrow-band communication frequency band can pass through the narrow-band communication frequency band, and the same communication frequency signal passing through the narrow-band communication frequency band can only be received by the receiver matched with the narrow-band communication frequency band, that is, each narrow-band communication frequency band can represent signals with different communication frequencies, and the transmission of signals with different communication frequencies has uniqueness, in other words, devices in the same narrow-band communication frequency band can communicate with each other, thereby preventing the interference of devices in other frequency bands. Therefore, through the utility model discloses a multichannel narrow frequency communication device can realize the conveying and the transmission of one-to-one of target signal, improves the uniqueness and the accuracy of information communication.

It is worth noting that although the difference the communication frequency of narrow frequency communication frequency channel is different, makes the difference can't realize signal communication between the narrow frequency communication frequency channel, but the utility model discloses a channel switching technique is from one of setting for with the communication frequency channel of transmitter the narrow frequency communication frequency channel switches to required another the narrow frequency communication frequency channel, so that the transmitter transmission with another narrow frequency communication frequency channel assorted signal, and the receiver can only receive with the narrow frequency communication frequency channel assorted signal of self setting for, and then realizes different carry out noiseless ground communication between the narrow frequency communication frequency channel. In other words, when communication needs to be performed between different communication frequency bands, the communication can be switched to the set narrow-band communication frequency band first, and then signals required to be transmitted are loaded, so that interference-free communication can be performed between different narrow-band communication frequency bands.

For example, the narrow-band communication band a is set to load the signal to be transmitted, after the transmission is completed, the transmission is switched to the set narrow-band communication band B to load the signal to be transmitted, and then the transmission is completed. By analogy, the signal can be transmitted in a plurality of hopping narrow-band communication frequency bands, and the same frequency interference is avoided.

It should be noted that, in the above embodiments of the present invention, as shown in fig. 1, the step S120 of the multi-channel narrow-band communication device includes the steps of:

s121: loading and transmitting a first channel signal in a preset first narrow-band communication frequency band; and

s122: after the first channel signal is transmitted, switching to a second narrow-band communication frequency band to load and transmit a second channel signal, wherein the communication frequency of the first narrow-band communication frequency band is different from the communication frequency of the second narrow-band communication frequency band.

It should be noted that the signal can only be transmitted by a transmitter that is preset or switched to the matched narrow frequency communication band; and the signal can only be received by a receiver of the narrow frequency communication band that is preset to match. That is, the first (or second) signal can only be transmitted by a transmitter that is previously set or switched to the first (or second) narrowband communication band; and the first (or second) signal can only be received by a receiver that is previously set to the first (or second) narrowband communication frequency band. In other words, when the transmitter is set to the first narrowband communication band in advance, or the transmitter is controlled to switch to the first narrowband communication band, the transmitter can load and transmit the first channel signal; when the receiver is set to the first narrow-band communication frequency band in advance, the receiver can receive the first channel signal to ensure the interference-free transmission of the signal. That is, in this example of the invention, no channel switching occurs for the receiver. Of course, in other examples of the present invention, when the receiver is not configured in advance for the first narrow-band communication frequency band, the receiver may also be controlled to switch to the first narrow-band communication frequency band, and then receive the first channel signal.

Further, in an example of the present invention, as shown in fig. 1, the step S120 may further include the step of:

s123: after the second channel signal is transmitted, switching to a third narrow-band communication band to load and transmit the third channel signal, wherein the communication frequency of the third narrow-band communication band is different from the communication frequency of the first and second narrow-band communication bands.

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

It is understood that, in this example of the present invention, after the second channel signal transmission is completed, the second narrowband communication band is not automatically restored to the first narrowband communication band, but is directly switched from the second narrowband communication band to the third narrowband communication band, and the third channel signal is waited to be transmitted. And analogizing in turn, and skipping back to the first narrow-frequency communication frequency band again until all the set narrow-frequency communication frequency bands are skipped and the signals are sent. In other words, after all the narrow-band communication bands have sent signals, the first narrow-band communication band will be skipped back (i.e. only one channel switching reset is needed).

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, switching from the second narrow-band communication frequency band to the first narrow-band communication frequency band, switching from the first narrow-band communication frequency band to a set third narrow-band communication frequency band, and waiting for sending the third channel signal, wherein the communication frequency of the third narrow-band communication frequency band is different from the communication frequencies of the first and second narrow-band communication frequency bands.

It can be understood that in this example of the present invention, after the second channel signal transmission is completed, the second narrow-band communication band is switched back to the first narrow-band communication band, and then the first narrow-band communication band is switched to the third narrow-band communication band to wait for the third channel signal to be transmitted. By analogy, after the second or third channel signal is sent each time, the first narrow-band communication frequency band needs to be switched first (i.e. multiple channel switching resets are needed), until all the narrow-band communication frequency bands send the signal.

In particular, in some embodiments of the present invention, the number of the channel signals in the same narrow frequency communication band is not limited, and in particular, the first channel signals transmitted in the step S121 have different coding addresses, so that the first channel signals with different coding addresses can be received only by a receiver matched with the narrow frequency communication band, and the corresponding first channel signals are loaded when the corresponding coding addresses are matched with the receiver, so that the transmission targets of the channel signals with different coding addresses in the same narrow frequency communication band are unique, and therefore the transmissions between the channel signals with different coding addresses do not interfere with each other, thereby improving the reliability of information transmission, and simultaneously improving the communication volume of each narrow frequency communication band to facilitate the improvement of communication efficiency, the method is favorable for packet communication and is convenient for realizing batch accurate control.

Those skilled in the art should understand that the channel signal is encoded information having encoded guiding information, a key, address information, a control command and verification information, wherein the encoded address of the channel signal should be understood as the encoded information that can be recognized by a corresponding receiver to load the control command and the verification information, i.e. the encoded address is one or a combination of two or more of the guiding information, the key and the address information in the encoded information, which is not limited by the present invention. That is to say, the same difference under the narrow frequency communication frequency channel the channel signal is the channel signal that has different code addresses, and does not restrict the control command information of channel signal, and does not restrict the difference the code address and the control command of the channel signal of narrow frequency communication frequency channel, and is different promptly the code address and/or the control command of the channel signal of narrow frequency communication frequency channel can be the same, also can the diverse, the utility model discloses do not limit this.

Illustrative System

Referring to fig. 2 to 5, a multi-channel narrow-band communication device according to an embodiment of the present invention is illustrated, which can implement interference-free communication to solve the problems of co-channel interference or communication conflict in the prior art. Specifically, as shown in fig. 2, the multi-channel narrowband communication device 1 includes at least one first master 11, at least one second master 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 narrow frequency communication band for being triggered to transmit a first channel signal matching the first narrow frequency communication band. Each of the second hosts 12 includes a second host transmitter 121, wherein the second host transmitter 121 is configured to have a second narrow-band communication band for being triggered to transmit a second channel signal matching the second narrow-band communication band, wherein the communication frequency of the second narrow-band communication band is different from the communication frequency of the first narrow-band communication band, that is, the frequency band of the first channel signal is different from the frequency band of the second channel signal. Each of the first receiving slaves 21 is configured to have the first narrow frequency communication band for receiving the first channel signal matched with the first narrow frequency communication band. Each of the second receiving slaves 22 is configured to have the second narrow frequency communication band for receiving the second channel signal matched with the second narrow frequency communication band.

In other words, the first receiving slave 21 can only receive the first channel signal from the first master 11 due to being set to the first narrowband communication frequency band; likewise, the second receiving slave 22 can only receive the second channel signal from the second master 12 due to being configured to the second narrowband communication band. That is, the first receiving slave 21 does not receive the second channel signal from the second master 12, and similarly, the second receiving slave 22 does not receive the first channel signal from the first master 11, so as to avoid the problem of communication collision or co-channel interference between the masters, and implement high-speed interference-free communication in the same narrow-band communication band.

It should be noted that a certain communication frequency band is divided into at least two narrow frequency communication frequency bands (such as the first narrow frequency communication frequency band and the second narrow frequency communication frequency band), and communication frequencies of the narrow frequency communication frequency bands are different from each other, so that a communication frequency of the first narrow frequency communication frequency band is different from a communication frequency of the second narrow frequency communication frequency band, that is, a communication frequency range of the first narrow frequency communication frequency band is not overlapped with and not crossed with a communication frequency range of the second narrow frequency communication frequency band, so as to avoid mutual interference or influence of the first channel signal and the second channel signal during transmission to the maximum extent. For example, the communication frequency of the first narrow-band communication band may be greater than or equal to 863MHZ and less than 863.1875 MHZ; the communication frequency of the second narrow-band communication band can be greater than or equal to 863.1875MHz and less than 863.375 MHz.

It should be noted that, in this embodiment of the present invention, as shown in fig. 2, the multi-channel narrow-band communication device 1 may further include at least one third master 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 narrow frequency communication band for being triggered to transmit a third channel signal matched with the third narrow frequency communication band, wherein the communication frequency of the third narrow frequency communication band is different from the communication frequency of the first and second narrow frequency communication bands. Each of the third receiving slave machines 23 is configured to have the third narrow frequency communication band, and is configured to receive the third channel signal matched with the third narrow frequency communication band, so as to perform interference-free communication between the master machine and the slave machine having the same narrow frequency communication band, thereby effectively avoiding communication collision or communication interference between the master machine and the slave machine having different narrow frequency communication bands.

It is worth noting in the above embodiments of the present invention, although the advantages and features of the multi-channel narrow-band communication device 1 are illustrated by way of example through the first narrow-band communication band, the second narrow-band communication band and the third narrow-band communication band, the multi-channel narrow-band communication device 1 is not limited to these three narrow-band communication bands, in other examples of the present invention, the multi-channel narrow-band communication device 1 may further have a plurality of narrow-band communication bands such as fourth, fifth and sixth, that is, the number of the multi-channel narrow-band communication device 1 that may include the narrow-band communication bands may be more than three. Furthermore, first narrow frequency communication frequency channel second narrow frequency communication frequency channel and the communication frequency of third narrow frequency communication frequency channel can be continuous, also can be discontinuous, the utility model discloses do not further limit to this.

Further, as shown in fig. 2, in the multi-channel narrow-band communication device 1 according to this embodiment of the present invention, the first host 11 may further include a first receiving host 112, wherein the first receiving host 112 is configured to have the first narrow-band communication band for receiving the first channel signal in the first narrow-band communication band; the second host 12 may further include a second receiver host 122, wherein the second receiver host 122 is configured to have the second narrow frequency communication band for receiving a second channel signal in the second narrow frequency communication band; the third host 13 may further include a third receiver host 132, wherein the third receiver host 132 is configured to have the third narrowband communication band for receiving a third channel signal with the third narrowband communication band. Thus, when the first transmitting host 111 of one of the first hosts 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 one of the first hosts 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 perform interference-free communication between hosts having the same narrow-band communication channel.

It is worth noting that the multi-channel narrow-band communication device 1 of the present invention can be applied to the technical fields such as the lighting field, the security field, etc. to ensure the self-management and energy saving of the lighting system or the alarm system. As an example of a lighting system, the first, second and third master 11, 12, 13 of the multi-channel narrow-band communication device 1 are adapted to be communicatively connected to master induction luminaires of the lighting system, and the first, second and third receiving slaves 21, 22, 23 of the multi-channel narrow-band communication device 1 are adapted to be communicatively connected to slave induction luminaires of the lighting system. The main sensing lamp of the lighting system can actively sense moving objects or people around, so that when sensing that moving objects or people exist around, the main sensing lamp automatically adjusts, such as is lighted and/or is controlled by dimming, and triggers the transmitting main machines of the first, second and third main machines 11, 12, 13 to transmit corresponding signals. Although the slave induction lamp of the lighting system cannot actively sense the surrounding moving objects or people, when the first, second and third receiving slaves 21, 22 and 23 receive corresponding signals, the slave induction lamp of the lighting system automatically lights up in response to the signals received by the receiving slaves, thereby realizing the automatic management function of the lighting system.

It is to be understood that the main sensing light fixture of the lighting system may be, but is not limited to, implemented as a light fixture configured with a microwave detector to sense a surrounding moving object or person by the microwave detector; whereas the slave induction lamps of the lighting system are implemented as lamps not provided with microwave detectors in order to reduce the cost of the whole lighting system. Of course, in other examples of the present invention, the main sensing luminaire of the lighting system may also be implemented as a luminaire configured with sensing devices such as infrared detectors, sound detectors, image detectors, and the like.

Illustratively, as shown in fig. 3A and 3B, a first application scenario of the multi-channel narrow-band communication device according to the above-mentioned embodiment of the present invention is illustrated, which shows an application of the multi-channel narrow-band communication device in a broadcast mode, that is, the multi-channel narrow-band communication device needs to perform a broadcast operation and perform interference-free communication only in the same narrow-band communication band.

Specifically, as shown in fig. 3A, the first application scenario is an application scenario of lighting in a three-level corridor, where the main sensing lamp 31 is disposed at an entrance (or doorway) position of each level of corridor, and is used to sense people or moving objects entering or exiting from the entrance, and the auxiliary sensing lamp 32 is disposed at another position (i.e., a non-entrance position) of each level of corridor. Providing said first host 11 communicatively connected to said main induction light fixture 31 within a first level corridor (as providing said first host 11 at said main induction light fixture 31 within a first level corridor); and said first receiving slave 21 being communicatively connected to said slave induction luminaire 32 is arranged in the first level corridor (said first receiving slave 21 being arranged at said slave induction luminaire 32 as in the first level corridor). The second main machine 12 is arranged at all the main induction lamps 31 in the second layer of the corridor; and the second receiving slave 22 is arranged at all the slave induction luminaires 32 in the second level corridor. The third main machine 13 is arranged at all the main induction lamps 31 in the third-level corridor; and the third receiving slave 23 is arranged at all the slave induction lamps 32 in the third level corridor.

Thus, as shown in fig. 3B, when a certain main sensing light fixture 31 in the first-floor corridor senses a moving person or object, the main sensing light fixture 31 is lighted, and the first transmitting host 111 of the first host 11 located at the main sensing light fixture 31 is triggered to transmit the first channel signal. Then, the first receiving slave 21 and the first receiving master 112 in the first level corridor receive the first channel signal due to the first narrow frequency communication band, so that all the slave induction lamps 32 and other master induction lamps 31 in the first level corridor are lighted in response to the first channel signal. Meanwhile, the second and third receiving slave machines 22 and 23 and the second and third receiving master machines 112 and 113 in the second and third levels of corridors cannot receive the first channel signal due to the second and third narrow frequency communication bands, so that all the slave induction lamps 32 and other master induction lamps 31 in the second and third levels of corridors cannot be lighted, and the lamps in the second and third levels of corridors are prevented from being interfered by communication in the first level of corridors, which is favorable for achieving the purposes of automatic management and energy saving of the lighting system. In other words, the master and the slave in each layer of corridor transmit signals in the same narrow-band communication frequency band, and the master and the slave in the corridors of different layers transmit signals in different narrow-band communication frequency bands, so that communication interference between the master and the slave in the corridors of different layers is avoided, and broadcast control of the lighting system is realized in the corridors of the same layer. It can be understood that, when the main sensing lamp 31 senses a moving person or object, the first reflection host 111 may emit the first channel signal after the main sensing lamp 31 is turned on, or the first reflection host 111 may also emit the first channel signal before the main sensing lamp 31 is turned on, which is not described herein.

It is worth mentioning that, in the multi-channel narrow-band communication device 1 according to the present embodiment of the present invention, the first transmitting host 111 of the first host 11 can also be controlled to switch to the second narrow-band communication band for transmitting the second channel signal matched with the second narrow-band communication band, so that the second receiving host 122 of the second host 12 can receive the second channel signal from the first host 11, thereby implementing non-interference communication between the first host 11 and the second host 12, i.e. implementing non-interference communication between hosts with different narrow-band communication bands. In other words, when a certain master induction lamp 31 of the lighting system is turned on by sensing a moving person or object, the first transmitting master 111 of the first master 11 connected to the master 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 turned on; after the first channel signal is transmitted, the first transmitting host 111 switches to the second narrow-band 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 turned on.

Likewise, the second transmitting host 121 of the second host 12 can be controlled to switch to the third narrowband communication band for transmitting a third channel signal matching the third narrowband communication 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 narrow-band communication band for transmitting the second channel signal matched with the second narrow-band communication 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 implementing interference-free communication between hosts with different narrow-band communication bands.

Illustratively, as shown in fig. 4A and 4B, a second application scenario of the multi-channel narrowband communication apparatus according to the above embodiment of the present invention is illustrated, which shows an application of the multi-channel narrowband communication apparatus in a channel switching mode, that is, the multi-channel narrowband communication apparatus needs to perform a channel switching operation to perform interference-free communication in different narrowband communication frequency bands.

Specifically, as shown in fig. 4A, the second application scenario takes an application scenario of staircase lighting as an example, and the main sensing lamp 31 is disposed on each layer of staircase and is used for sensing a person or a moving object moving in the staircase. A first host 11 connected with the main induction lamp 31 in a communication mode is arranged in the first-floor staircase; a second host 12 connected with the main induction lamp 31 in a communication mode is arranged in the second-floor stairway; a third main unit 13 communicably connected to the main induction lamp 31 is provided in the third stairwell.

Thus, as shown in fig. 4B, when a person walks into a first-floor staircase, so that the main sensing lamp 31 located in the first-floor staircase senses that the walking person is illuminated, the first transmitting host 111 of the first host 11 is controlled to switch to the second narrow-frequency communication frequency band to transmit the second channel signal; then the second receiving host 122 of the second host 12 located in the second floor stairwell will receive the second channel signal, so that the main induction lamp 31 located in the second floor stairwell is lighted, thereby realizing that when a person walks in the first floor stairwell, the lamp located in the second floor stairwell is lighted in advance, so as to provide illumination for the person in advance. By analogy, when a person walks into a second-floor stairwell, so that the main induction lamp 31 located in the second-floor stairwell senses the walking person, the second transmitting host 121 of the second host 12 is controlled to switch to the third narrow-band communication frequency band to transmit the third channel signal; then the third receiving host 132 of the third host 13 located in the third stairwell will receive the third channel signal, so that the main induction lamp 31 located in the third stairwell is lighted in advance to provide intelligent lighting service.

It should be noted that when the main sensing lamp 31 in the second-floor stairwell senses a walking person, it cannot be determined whether the person goes upstairs or downstairs, so 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 narrow-band communication band to transmit the first channel signal, so that the first receiving host 112 of the first host 11 in the first-floor stairwell receives the first channel signal to light the lamp in the first-floor stairwell in advance. In other words, the second transmitting host 121 of the second host 12 can switch to the third narrow frequency communication band to transmit the third channel signal, and then switch to the first narrow frequency communication band to transmit the first channel signal, so that the second host 12 can perform interference-free communication with the third host 13 and the first host 11, respectively.

It can be understood that the main induction lamp 31 of the lighting system of the present invention can operate in a low brightness mode and a high brightness mode, and when the main induction lamp 31 operates in the low brightness mode, the brightness of the light emitted by the main induction lamp 31 is low, so as to consume less electric energy; when the main induction lamp 32 works in the high-brightness mode, the brightness of the light emitted by the main induction lamp 31 is higher, so that more electric energy is consumed.

Of course, in other examples of the present invention, the low brightness mode of the main induction lamp 31 refers to: when another channel signal is received, the low-light state is entered to realize the effect of lighting in advance. The high brightness mode of the main induction lamp 31 is as follows: when another channel signal is received, a highlight state is entered to enhance the illumination effect.

Preferably, when the main sensing lamp 31 senses a moving person or object, the main sensing lamp 31 will be lighted to operate in a high brightness mode to provide better lighting conditions regardless of whether a receiving host connected to the main sensing lamp 31 receives a channel signal; when the main induction lamp 31 does not induce 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 is turned on to operate in a low brightness mode, so as to save resources; if the receiving host connected to the main sensing lamp 31 does not receive the corresponding channel signal, the main sensing lamp 31 will not be turned on.

More preferably, the master induction lamp 31 and the slave induction lamp 32 of the lighting system can be automatically turned off after being turned on for a period of time (e.g. 1 minute, etc.), so as to save energy. Even in some examples of the present invention, the main induction lamp 31 of the lighting system is turned on to operate in the high-brightness mode for a period of time (e.g., 30 seconds, etc.) and then turned off after continuing to operate in the low-brightness mode for a period of time (e.g., 30 seconds, etc.), so as to find a reasonable balance point between providing better lighting conditions and saving resources.

According to the above embodiment of the present invention, the first transmitting host 111 of the first host 11 of the multi-channel narrow-band communication device 1 can be switched to the third narrow-band communication band to transmit a third channel signal after the second channel signal is transmitted, in addition to being triggered to transmit the first channel signal first and then being switched to the second narrow-band communication band to transmit 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 receive the second channel signal and the third channel signal from the first host 11 respectively, 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 a first narrow frequency communication band to transmit the first channel signal, and switch to a third narrow frequency communication band to transmit the third channel signal; the third transmitting host 131 of the third host 13 can also switch to the first narrow band communication band to transmit the first channel signal and switch to the second narrow band communication band to transmit the second channel signal, thereby achieving interference-free communication between multiple hosts with different narrow band communication bands.

It is noted that in this example of the present invention, the first receiving slave 21 can receive the first channel signal due to the first narrow frequency communication band, but the slave induction lamp 32 connected to the first receiving slave 21 does not respond to the first channel signal, that is, the slave induction lamp 32 is not turned on due to the first receiving slave 21 receiving the first channel signal. In other words, the slave induction lamp 32 connected to the first receiving slave 21 is only lighted in response to the first channel signal and is not lighted in response to the first channel signal, so as to prevent the slave induction lamp 32 from being lighted accidentally or unintentionally, which contributes to energy saving. 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 is not turned on in response to the second and third channel signals.

Of course, in other examples of the present invention, the slave induction lamp 32 connected to the first, second and third receiving slave machines 21, 22 and 23 may be lighted in response to the first, second and third channel signals, in addition to being lighted in response to the first, second and third channel signals, respectively, so as to realize interference-free communication between the master machine and the slave machine having different narrow frequency communication bands.

Illustratively, as shown in fig. 5A and 5B, a third application scenario of the multi-channel narrow-band communication device according to the above-described embodiment of the present invention is illustrated, which shows an application of the multi-channel narrow-band communication device in a hybrid mode, that is, the multi-channel narrow-band communication device requires both a broadcast operation and a channel switching operation for communication without interference in the same and different narrow-band communication bands.

Specifically, as shown in fig. 5A, the third application scenario is an application scenario of lighting of an underground parking lot, where the underground parking lot is divided into an area a, an area B, and an area C, and the area a, the area B, and the area C are distributed in a T shape. The area a, the area B and the area C are provided with the master induction lamp 31 and the slave induction lamp 32, and are arranged as shown in fig. 5A. In zone a, the master communicably connected to the master induction lamp 31 is the first master 11, and the slave communicably connected to the slave induction lamp 32 is the first receiving slave 21; within zone B, the master communicably connected with the master induction luminaire 31 is the second master 12, and the slave communicably connected with the slave induction luminaire 32 is the second receiving slave 22; in zone C, the master communicably connected to the master induction lamp 31 is the third master 13, and the slave communicably connected to the slave induction lamp 32 is the third receiving slave 23.

Thus, as shown in fig. 5B, when the master induction lamp 31 located in the area a senses that a vehicle or a person moves in the area a to be lit, the first transmitting master 111 of the first master 11 connected to the master induction lamp 31 in the area a is triggered to transmit a first channel signal, so that the first receiving master 112 and the first receiving slave 21 of the other first masters 11 can both receive the first channel signal to light the other master induction lamps 31 connected to the first master 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 lamps 32 located in the area a are both lit. Then, after the first channel signal is transmitted, the first transmitting host 111 of the first host 11 is controlled to switch to a second narrow frequency communication 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 the main induction lamp 31 connected to the second host 12, that is, the main induction lamp 31 located in the B zone is lighted. Finally, after the second channel signal is transmitted, the first transmitting host 111 of the first host 11 is controlled to switch to a third narrow-band 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 the main induction lamp 31 connected to the third host 13, that is, the main induction lamp 31 located in the zone C is turned on. It should be noted 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 zone B is not lighted in response to the second channel signal, and the slave induction lamp 32 located in the zone C is not lighted in response to the third channel signal, so as to achieve the purpose of saving resources.

Likewise, when the master induction lamp 31 located in the zone B senses that a vehicle or a person moving to the zone B is to be lighted, the second transmitting master 121 of the second master 12 connected to the master induction lamp 31 in the zone B is triggered to transmit a second channel signal, so that the second receiving master 122 and the second receiving slave 22 of the other second master 12 can both receive the second channel signal to light the other master induction lamps 31 connected to the second master 121 and the slave induction lamps 32 connected to the second receiving slave 22, that is, the master induction lamps 31 and the slave induction lamps 32 located in the zone B are both lighted. Then, after the second channel signal is transmitted, the second transmitting host 121 of the second host 12 is controlled to switch to a third narrow-band 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 the main induction lamp 31 connected to the third host 13, that is, the main induction lamp 31 located in the zone C is turned on. Finally, after the third channel signal is transmitted, the second transmitting host 121 of the second host 12 is controlled to switch to a first narrow-band 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 the main induction lamp 31 connected to the first host 11, that is, the main induction lamp 31 located in the area a is turned on.

It should be noted that when the main sensing lamp 31 located in the area a senses a walking person or a moving vehicle, it cannot be determined whether the person or the vehicle moves to the area B or the area C, so 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 narrow frequency communication band to transmit the second channel signal, so that the second receiving host 122 of the second host 12 located in the area B receives the second channel signal to light the main sensing lamp 31 located in the area B in advance; however, the second receiving slave 22 in the zone B will not light the slave sensing lamp 32 in the zone B although it will receive the second channel signal, so as to prevent the slave sensing lamp 32 from being lighted in advance or uselessly to waste energy. Similarly, the first transmitting host 111 of the first host 11 can also be controlled to switch to the third narrowband communication band to transmit the third channel signal, so that the third receiving host 132 of the third host 13 located in the C zone receives the third channel signal to turn on the main induction lamp 31 located in the C zone in advance; however, the third receiving slave 23 located in the C zone will not light the slave induction lamp 32 located in the C zone although it will receive the third channel signal, so as to prevent the slave induction lamp 32 from being lighted in advance or uselessly to waste energy.

Illustratively, as shown in fig. 6A to 6F, a fourth application scenario of the multi-channel narrow-band communication device according to the above-mentioned embodiment of the present invention is illustrated. As shown in fig. 6A and 6B, a first situation of the multi-channel narrow-band communication device in a fourth application scenario is shown, where the fourth application scenario is an application scenario of road lighting, and a plurality of main sensing lamps 31, 31', 31 ″ are disposed on both left and right sides of a road for sensing people or vehicles walking on the road. It is worth mentioning that the highway is further provided with the first host 11 communicably connected to the main induction luminaires 31,31 ', respectively, and the second host 12 communicably connected to the main induction luminaires 31', 31 ", respectively.

Specifically, the main induction lamp 31 and the main induction lamp 31 'communicate with each other through the first narrow frequency communication band, and the main induction lamp 31' and the main induction lamp 31 ″ communicate with each other through the second narrow frequency communication band. Specifically, when a vehicle or a person moves into the lighting area of the main sensing lamp 31, the main sensing lamp 31 senses the movement of the vehicle or the person and is turned on, the first transmitting host 111 of the first host 11 is triggered to transmit the first channel signal, wherein the first receiving host 112 of the first host 11 receives the first channel signal and turns on the main sensing lamp 31' in advance. And when the car or the person further moves into the lighting area of the main induction lamp 31', the second transmitting host 121 of the second host 12 is triggered to transmit the second channel signal, wherein the second receiving host 122 of the second host 12 receives the second channel signal to previously light up the main induction lamp 31 ″. It can be understood that the first channel signal cannot be communicated in the second narrow band communication band, and the second channel signal cannot be communicated in the first narrow band communication band, that is, the first narrow band communication band can only be used for transmitting and receiving the first channel signal, and the second narrow band communication band can only be used for transmitting and receiving the second channel signal, so that the communication between the first narrow band communication band and the second narrow band communication band is not interfered with each other. That is to say, each narrow-band communication band represents the transmission of signals with different communication frequencies, and the communication of the signals with different communication frequencies has uniqueness, so that the data transmission speed can be increased and the data transmission accuracy can be improved.

It is to be understood that fig. 6A and 6B illustrate a point-to-point communication mode of the multi-channel narrowband communication device. In this embodiment, the main induction lamp 31 transmits signals to the main induction lamp 31 'through the first narrow frequency communication band, and the main induction lamp 31' transmits signals to the main induction lamp 31 ″ through the second narrow frequency communication band. In some embodiments of the present invention, the main sensing lamp 31 ″ may also be set to transmit signals to the main sensing lamp 31 'through the first narrow-band communication band and correspondingly the main sensing lamp 31' transmits signals to the main sensing lamp 31 through the second narrow-band communication band. And in some embodiments of the present invention, the main induction lamp 31 can also communicate with the main induction lamps 31 ', 31 "through the first narrow frequency communication band and the second narrow frequency communication band, respectively, that is, the main induction lamps 31, 31', 31" can be set to communicate with different communication frequencies, which is not limited by the present invention.

As shown in fig. 6C and 6D, the second case of the multi-channel narrow-band communication device in the fourth application scenario is illustrated, specifically, a road 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 lamps 31 and 31 'are configured to communicate through the first narrow-band communication band, and the main induction lamps 31' and 31 ″ are configured to communicate through the second narrow-band communication band.

Specifically, when the main sensing lamp 31 ' senses that a car or a person moves, the main sensing lamp 31 ' is controlled to be turned on, 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 sensing lamp 31 ' are simultaneously triggered. Specifically, the first transmitting host 111 of the first host 11 sends the first channel signal to the first receiving host 112, so as to light the main induction lamp 31 in advance; the second transmitting host 121 of the second host 12 transmits the second channel signal to the second receiving host 122, so as to light the main induction lamp 31 ″ in advance, and 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 narrow-band communication frequency band and the second narrow-band communication frequency band, so that the main induction lamp 31' does not interfere with the communication between the main induction lamp 31 and the main induction lamp 31 ″.

It is worth mentioning that the communication between the main induction lamp 31' and the main induction lamp 31 "can also be performed through a control mode. Specifically, when the main induction lamp 31' is turned on and triggers the first transmitting host 111, the first transmitting host 111 first transmits the first channel signal to the first receiving host 112 to turn on the main induction lamp 31 in advance, and then the first transmitting host 111 is switched to the second narrow frequency communication band to transmit the second channel signal, and the second receiving host 122 of the second host 12 receives the second channel signal to turn on 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 transmitted by the first transmitting host 111, the second receiving host 122 still receives the signal transmitted by the second narrow frequency communication 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 narrow frequency communication band and the second narrow frequency communication band, respectively, without mutual interference.

That is to say, multichannel narrow frequency communication device can realize the switching between the different narrow frequency communication frequency channels and select different narrow frequency communication frequency channels to communicate, is favorable to expanding multichannel narrow frequency communication device's range of application and improvement communication efficiency, wherein can understand, the switching order of first host computer 111 between the narrow frequency communication frequency channels of difference can be set up and be favorable to realizing the control that has definite directionality, if point-to-point one send and receive control, point forward control and point backward control, the utility model discloses not limit to this.

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

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 turned on in advance, so that in practical applications, the lamps can be turned on in advance without determining the moving direction of the vehicle or the person for practical use.

As shown in fig. 6E and 6F, a third case of the multi-channel narrowband communication apparatus in a fourth application scenario is illustrated, which shows an application mode of the multi-channel narrowband communication apparatus in combination with a coded address. In particular, the road is provided with said first hosts 11 communicably connected with said main induction luminaires 31, 31', 31 ", respectively, wherein said first hosts 11 comprise one said first emitting host 111 and two said first receiving hosts 112.

Specifically, when the main sensing lamp 31 'senses that a car or a person moves, the main sensing lamp 31' is controlled to be turned on and trigger the first transmitting host 111 of the first host 11, wherein the first transmitting host 111 respectively transmits the first channel signal assigned with a first address and the first channel signal assigned with a second address to the two first receiving hosts 112, so as to turn on the main sensing lamp 31 and the main sensing lamp 31 ″ respectively in advance.

It can be understood that, since the first channel signals respectively transmitted by the first transmitting host 111 have different coding addresses, the first receiver 112 only matching with the coding address can receive the first channel signal having the coding address, and therefore the transmission targets of the first channel signals having different coding addresses are unique, so that the transmission of the first channel signals having different coding addresses will not interfere with each other, thereby improving the reliability of information transmission, and simultaneously improving the communication volume of each narrow-band communication band to facilitate the improvement of communication efficiency, and facilitating packet communication to facilitate the realization of precise control in batches.
