Description

[Technical Field]

[0001] The present invention relates to a monitoring device, in particular an energy saving monitoring device, and further to a lighting system including such a monitoring device. [Background technology]

[0002] A conventional monitoring device supports Bluetooth mesh and communicates bidirectionally with a lighting system through Bluetooth mesh. The monitoring device includes a Bluetooth mesh module based on the existing Bluetooth mesh (BLE-mech) architecture. When the monitoring device detects a moving object (such as a person or a vehicle), the monitoring device sends a group message to the lighting device through the Bluetooth mesh module. The lighting device then sends the group message to other lighting devices in the same group, causing these lighting devices to simultaneously activate.

[0003] Because monitoring devices are battery-powered, their Bluetooth mesh modules must be kept in a sleep or shutdown state whenever possible to conserve power. While conventional monitoring devices are equipped with energy-saving mechanisms, these mechanisms are unable to effectively reduce power consumption, requiring users to frequently maintain the monitoring devices. Furthermore, the monitoring devices must receive signals from the Bluetooth mesh, which requires a signal reception function, resulting in increased power consumption. Furthermore, the monitoring devices must participate in periodic update operations (such as key updates) of the Bluetooth mesh, further increasing the power consumption of the monitoring devices. Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention provides an energy-saving monitoring device and a lighting system including the monitoring device. [Means for solving the problem]

[0005] The present invention provides a monitoring device including a beacon module, a detection module, and a processing module. The detection module performs a detection operation to detect a moving object and generate a detection signal. The processing module generates a beacon signal after receiving the detection signal and transmits the beacon signal to a lighting device via the beacon module. The processing module generates a check value based on a serial number, a group identifier, a monitoring identifier, and a random code representing the detection operation, generates a beacon signal including the serial number, the group identifier, the monitoring identifier, and the check value, and operates the lighting device according to the beacon signal.

[0006] In one refinement of the invention, the monitoring device according to claim 1, characterized in that the processing module periodically transmits a beacon signal to the lighting device multiple times.

[0007] In a refinement of the invention, the processing module goes to sleep after completing the transmission of the beacon signal.

[0008] In a refinement of the invention, the processing module generates a random code based on the serial number.

[0009] In a refinement of the invention, the beacon signal further comprises a customized beacon value and an organization identifier.

[0010] The present invention further provides a lighting system including a lighting device group and a monitoring device. The lighting device group includes one or more lighting fixtures. The monitoring device performs a detection operation, detects a moving object, and generates a detection signal. After generating the detection signal, the monitoring device generates a beacon signal and transmits the beacon signal to the lighting devices in the lighting device group. The monitoring device generates a check value based on a serial number, a group identifier, a monitoring identifier, and a random code representing the detection operation, and generates a beacon signal including the serial number, the group identifier, the monitoring identifier, and the check value. The lighting device activates other lighting devices in the lighting device group or discards the beacon signal according to the beacon signal.

[0011] In a refinement of the invention, the monitoring device periodically transmits a beacon signal to the lighting device multiple times.

[0012] In one refinement of the invention, the monitoring device goes into a sleep state after completing the transmission of the beacon signal.

[0013] In one refinement of the invention, the monitoring device generates a random code based on the serial number.

[0014] In a refinement of the invention, the beacon signal further comprises a customized beacon value and an organization identifier. [Effects of the Invention]

(1) The monitoring device of the present invention includes a beacon module, a detection module, and a processing module. The detection module performs a detection operation, detects a moving object, and generates a detection signal.

Here, the lighting device performs a verification process based on the beacon signal and, after confirming that the beacon signal is valid, sends a group message to other lighting devices belonging to the same group as the lighting device, causing these lighting devices to enter an awake state. The processing module enters a sleep state after completing the transmission of the beacon signal to reduce power consumption. From the above, it can be seen that the processing module of the monitoring device can enter a sleep state after completing the transmission of the beacon signal, thereby significantly reducing power consumption and battery consumption.

For ease of understanding, the same elements in the following embodiments will be denoted and described with the same reference numerals.

[0019] Please refer to FIGS. 1 and 2. FIG. 1 is an explanatory diagram of a lighting system according to a first embodiment of the present invention. FIG. 2 is a block diagram of a monitoring device for the lighting system according to the first embodiment of the present invention. As shown in FIG. 1, the lighting system 1 can be installed in a building (such as a parking lot, an office building, a large supermarket, or a department store) and includes four lighting device groups G1, G2, G3, and G4 and four monitoring devices S1, S2, S3, and S4. The four lighting device groups G1, G2, G3, and G4 are installed in different areas of the building, respectively. The four monitoring devices S1, S2, S3, and S4 are installed in appropriate locations, respectively. The lighting device group G1 includes a plurality of lighting devices LD (although only five lighting devices LD are shown in the figure, this is an example and not a limitation, and the number of lighting devices LD can be changed according to actual needs). The lighting device group G2 includes a plurality of lighting devices LD. The lighting device group G3 includes a plurality of lighting devices LD. The lighting device group G4 includes a plurality of lighting devices LD. Each lighting device LD is a Bluetooth mesh node. The monitoring device S1 corresponds to the lighting device group G1. The monitoring device S2 corresponds to the lighting device group G2. The monitoring device S3 corresponds to the lighting device group G3. The monitoring device S4 corresponds to the lighting device group G4. The numbers of the lighting device groups G1, G2, G3, and G4 and the monitoring devices S1, S2, S3, and S4 are merely examples and are not limited thereto and can be changed according to actual needs. The lighting device LD has a detection function, and after detecting a moving object, it wakes up, generates a group message, and wakes up other lighting devices LD in the same group. The monitoring device S1 has a detection function, and after detecting a moving object, it can generate a beacon signal to wake up the lighting device group G1. Similarly, after detecting a moving object, the monitoring device S2 can generate a beacon signal to wake up the lighting device group G2. After detecting a moving object, the monitoring device S3 can generate a beacon signal to wake up the lighting device group G3. After detecting a moving object, the monitoring device S4 can generate a beacon signal to activate the lighting device group G4. The monitoring devices S1, S2, S3, and S4 can be installed in places where there are no lighting devices LD, improving the detection ability of the entire mesh.

[0020] The monitoring device S1 includes a beacon module S13, a detection module S12 and a processing module S11. Since the four monitoring devices S1, S2, S3 and S4 have the same structure and operation mechanism, this embodiment will take the monitoring device S1 as an example.

[0021] The detection module S12 performs a detection operation to detect moving objects (people, vehicles, etc.) and generate a detection signal. In one embodiment, the detection module S12 may be an infrared sensor. In another embodiment, the detection module S12 may be a microwave sensor or other similar component.

[0022] After receiving the detection signal, the processing module S11 generates a beacon signal and transmits the beacon signal to one lighting device LD in the lighting device group G1 via the beacon module S13, causing the lighting device LD to operate according to the beacon signal. In one embodiment, the processing module S11 may be a microcontroller (MCU). In another embodiment, the processing module S11 may be a central processing unit (CPU), an application specific integrated circuit chip (ASIC), a field programmable gate array (FPGA), or other similar components. In one embodiment, the beacon module S13 may be a Bluetooth beacon signal processing circuit or other existing circuit having similar functions.

[0023] In this embodiment, the processing module S11 generates a check value based on the serial number, group identifier, monitoring identifier, and random code indicating the detection operation, and then generates a beacon signal including the serial number, group identifier, monitoring identifier, and check value. After completing the transmission of the beacon signal, the processing module S11 can enter a sleep state, thereby reducing the power consumption of the monitoring device S1 and reducing battery power consumption.

[0024] Furthermore, the monitoring device S1 can achieve the lighting device group control function through a one-way beacon signal communication mechanism, eliminating the need for signal reception from the Bluetooth mesh network. This further reduces the power consumption of the monitoring device S1 and reduces battery consumption. This makes maintenance of the monitoring device S1 more convenient and meets the requirements of practical applications.

[0025] Furthermore, the monitoring device S1 can achieve the lighting device group control function through a one-way beacon signal communication mechanism, and does not need to participate in the periodic update operations (such as key update) of the Bluetooth mesh. This significantly reduces the power consumption of the monitoring device S1, further reducing the battery power consumption. This makes maintenance of the monitoring device S1 more convenient and meets the requirements of practical applications.

[0026] As described above, the detection module S12 performs a detection operation to detect a moving object and generate a detection signal. After receiving the detection signal, the processing module S11 generates a beacon signal and transmits the beacon signal to one lighting device LD in the lighting device group G1 via the beacon module S13. In this embodiment, the format of the beacon signal can include a length, a customized beacon value, an organization identifier, a serial number, a group identifier, a monitoring identifier, and a check value, as shown in the table below:

[0027] [Table 1]

[0028] The customized beacon value (beacon type) may be 0xFF or 0x16, and the organization identifier is an identifier assigned to a specific group by the Bluetooth Special Interest Group (SIG). The above two values ​​are standardized by the Bluetooth SIG and should be well known to those skilled in the art, so they will not be described in detail here. The group identifier is the identifier of the group to which the monitoring device S1 belongs, and the monitoring identifier is the device identifier of the monitoring device S1.

[0029] After receiving the detection signal, the processing module S11 adds 1 to the serial number of the previous detection operation to set the serial number of the current detection operation. Next, the processing module S11 generates a random code based on the serial number of the current detection operation (this random code can be calculated using various existing random code algorithms using this serial number as a seed for random code generation), and executes a hash algorithm to obtain first data (sha1_out

[20] ), which is 20 bytes of data. In this embodiment, the hash algorithm is SHA1. In another embodiment, the hash algorithm may be SHA2 or another similar algorithm.

[0030] Next, the processing module S11 obtains the second data by grouping it based on the arrangement of 20 bytes of the first data (the arrangement order is that the radix bytes are grouped into one group and the even bytes are grouped into another group), which includes two groups (sha1_odd

[10] and sha1_even

[10] ).

[0031] Next, the processing module S11 performs a cyclic redundancy check algorithm based on the second data to obtain third data, which is two bytes of data (odd_crc and even_crc). In this embodiment, the cyclic redundancy check algorithm is crc8. In other embodiments, the cyclic redundancy check algorithm may be crc7, crc16, crc32, or other similar algorithms.

[0032] Finally, the processing module S11 performs an XOR (Exclusive OR) algorithm based on the third data to obtain a one-byte check value. In this way, the processing module S11 can generate a customized beacon broadcast message as a beacon signal. The processing module S11 can periodically transmit a beacon signal to the lighting device LD several times through the beacon module S13. For example, the processing module S11 can transmit a beacon signal to the lighting device LD every 200 ms and repeat the above transmission five times. After that, the processing module S11 can enter a sleep state. From the above, it can be seen that the monitoring device S1 no longer functions as a Bluetooth mesh subnode, does not execute the Bluetooth mesh protocol, and only transmits a beacon signal (customized beacon broadcast message) at appropriate times.

[0033] Each lighting device LD must process the beacon signal mentioned above in addition to implementing the Bluetooth mesh protocol of the Bluetooth SIG. After receiving a beacon signal, the lighting device LD analyzes whether the serial number matches that of the previously received beacon signal. If the lighting device LD determines that the serial number of the received beacon signal matches that of the previously received beacon signal, the lighting device LD discards the beacon signal. If the lighting device LD determines that the serial number of the received beacon signal does not match that of the previously received beacon signal, the lighting device LD analyzes the check value to confirm whether it is valid. The lighting device LD calculates the check value in the same way (random code algorithm + parity grouping step + cyclic redundancy check algorithm XOR algorithm). If the check value calculated by the lighting device LD matches that of the beacon signal, the beacon signal is valid. Finally, the lighting device LD generates a group message according to the group identifier of the beacon signal and broadcasts this group message to other lighting devices LDs in the same group based on the Bluetooth mesh protocol to simultaneously activate these lighting devices LDs.

[0034] From the above, it can be seen that the monitoring device S1 can achieve the lighting device group control function through a one-way beacon signal communication mechanism, and does not need to receive signals from the Bluetooth mesh, so it does not need a signal reception function. This further reduces the power consumption of the monitoring device S1 and reduces battery power consumption. This makes maintenance of the monitoring device S1 more convenient and meets the needs of practical applications.

[0035] Furthermore, the monitoring device S1 can achieve the lighting device group control function through a one-way beacon signal communication mechanism, and does not need to participate in the periodic update operations (such as key update) of the Bluetooth mesh. This significantly reduces the power consumption of the monitoring device S1, further reducing the battery power consumption. This makes maintenance of the monitoring device S1 more convenient and meets the needs of practical applications.

[0036] In addition, the monitoring device S1 adds a random code based on the serial number to the beacon signal, and generates a check value through a hash algorithm, a parity grouping step, a cyclic redundancy check algorithm, and an XOR algorithm. The above-mentioned special custom encryption mechanism can effectively realize a one-way beacon signal communication mechanism and effectively prevent the beacon signal from being cracked. Therefore, the monitoring device S1 can improve the security of the lighting device mesh, further expanding its application and adapting to future development trends.

[0037] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or variations made based on the monitoring device and lighting system of this embodiment should still fall within the protection scope of the present invention.

[0038] 3 and 4 are first and second explanatory diagrams illustrating the operation of a lighting system according to a second embodiment of the present invention. Similarly, the lighting system 1 can be installed in a building (such as a parking lot, an office building, a large supermarket, or a department store) and includes four lighting device groups G1, G2, G3, and G4 and four monitoring devices S1, S2, S3, and S4. The four lighting device groups G1, G2, G3, and G4 are installed in different areas of the building, respectively. The four monitoring devices S1, S2, S3, and S4 are installed in appropriate locations. The lighting device group G1 includes multiple lighting devices LD (although only five lighting devices LD are shown in the figure, this is an example and not a limitation, and the number of lighting devices LD can be changed according to actual needs). The lighting device group G2 includes multiple lighting devices LD. The lighting device group G3 includes multiple lighting devices LD. The lighting device group G4 includes multiple lighting devices LD. Each lighting device LD is a Bluetooth mesh node. The monitoring device S1 corresponds to the lighting device group G1. The monitoring device S2 corresponds to the lighting device group G2. The monitoring device S3 corresponds to the lighting device group G3. The monitoring device S4 corresponds to the lighting device group G4. The numbers of the lighting device groups G1, G2, G3, and G4 and the monitoring devices S1, S2, S3, and S4 are merely examples and are not limited thereto, and can be changed according to actual needs. The lighting device LD has a detection function, and after detecting a moving object, it wakes up, generates a group message, and wakes up other lighting devices LD in the same group. The monitoring device S1 has a detection function, and after detecting a moving object, it can generate a beacon signal to wake up the lighting device group G1. Similarly, the monitoring device S2 can generate a beacon signal to wake up the lighting device group G2 after detecting a moving object. The monitoring device S3 can generate a beacon signal to wake up the lighting device group G3 after detecting a moving object. The monitoring device S4 can generate a beacon signal to wake up the lighting device group G4 after detecting a moving object. The monitoring devices S1, S2, S3, and S4 can be installed in places where there are no lighting devices LD, thereby improving the detection capability of the entire mesh.

[0039] As shown in FIG. 3, the monitoring device S1 performs a detection operation to detect a moving object MT (a person, a vehicle, etc.) and generates a detection signal Ds.

[0040] 4, the monitoring device S1 generates a beacon signal Bs and transmits the beacon signal Bs to one lighting device LD in the lighting device group G1. After completing the transmission of the beacon signal, the monitoring device S1 can enter a sleep state, thereby reducing the power consumption of the monitoring device S1 and reducing battery power consumption. Thereafter, the lighting device LD wakes up the other lighting devices LD in the lighting device group G1 in response to the beacon signal Bs.

[0041] Therefore, the monitoring device S1 can achieve the lighting device group control function through a one-way beacon signal communication mechanism, and does not need to receive signals from the Bluetooth mesh, eliminating the need for a signal reception function. This further reduces the power consumption of the monitoring device S1 and reduces battery power consumption. This makes maintenance of the monitoring device S1 more convenient and meets the needs of practical applications.

[0042] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or variations made based on the monitoring device and lighting system of this embodiment should still fall within the protection scope of the present invention.

[0043] Although conventional monitoring devices are equipped with energy-saving mechanisms, these mechanisms do not effectively reduce power consumption, requiring users to frequently maintain the monitoring devices. Furthermore, since the monitoring device needs to receive signals from the Bluetooth mesh, a signal reception function is required, which increases the power consumption of the monitoring device. Furthermore, the monitoring device needs to participate in periodic update operations (such as key updates) of the Bluetooth mesh, further increasing the power consumption of the monitoring device. In contrast, according to the first and second embodiments of the present invention, the monitoring device includes a beacon module, a detection module, and a processing module. The detection module performs a detection operation to detect a moving object and generate a detection signal. After receiving the detection signal, the processing module generates a beacon signal and transmits the beacon signal to the lighting device via the beacon module. The processing module generates a check value based on a serial number, a group identifier, a monitoring identifier, and a random code representing the detection operation, generates a beacon signal including the serial number, group identifier, monitoring identifier, and check value, and controls the lighting device to operate according to the beacon signal. Here, the lighting device performs a verification process based on the beacon signal. After verifying that the beacon signal is valid, it sends a group message to other lighting devices in the same group as the lighting device, causing these lighting devices to enter an awake state. After completing the transmission of the beacon signal, the processing module enters a sleep state to reduce power consumption. From the above, it can be seen that the processing module of the monitoring device can enter a sleep state after completing the transmission of the beacon signal, thereby significantly reducing power consumption and battery consumption. Therefore, users do not need to frequently maintain the monitoring device, making monitoring device maintenance more convenient and meeting the needs of practical applications.

[0044] Furthermore, based on the first and second embodiments of the present invention, the monitoring device can achieve the lighting device group control function through a one-way beacon signal communication mechanism, and does not need to receive signals from the Bluetooth mesh, eliminating the need for a signal reception function. This further reduces the power consumption of the monitoring device and reduces battery consumption. Therefore, the monitoring device can meet the needs of practical applications.

[0045] Furthermore, based on the first and second embodiments of the present invention, the monitoring device can achieve the lighting device group control function through a one-way beacon signal communication mechanism, and does not need to participate in the periodic update operation (such as key update) of the Bluetooth mesh. This significantly reduces the power consumption of the monitoring device, further reducing battery consumption. This makes the maintenance of the monitoring device more convenient and meets the needs of practical applications.

[0046] In addition, according to the first and second embodiments of the present invention, the monitoring device adds a random code based on the serial number to the beacon signal and generates a check value through a hash algorithm, a parity grouping step, a cyclic redundancy check algorithm, and an XOR algorithm. The above-mentioned special custom encryption mechanism can effectively realize a one-way beacon signal communication mechanism and effectively prevent beacon signal hacking. Therefore, the monitoring device can improve the security of the lighting device mesh, further expanding its applications and responding to future development trends.

[0047] Furthermore, based on the first and second embodiments of the present invention, the monitoring device can effectively reduce power consumption, thereby achieving the desired effect while reducing costs. Furthermore, the monitoring device can improve the security of the lighting device mesh. Therefore, the monitoring device achieves excellent practicality and can meet the requirements of different applications. From the above, it can be seen that the monitoring device based on the embodiments of the present invention can indeed achieve excellent technical effects.

[0048] 5 is a flowchart of a monitoring device control method according to a third embodiment of the present invention. As shown in the figure, the monitoring device control method according to this embodiment includes the following steps. Step S51: The detection module of the monitoring device performs a detection operation to detect a moving object and generate a detection signal. Step S52: After receiving the detection signal, the processing module of the monitoring device generates a check value based on the serial number, group identifier, monitoring identifier, and random code indicating the detection operation, and then generates a beacon signal including the serial number, group identifier, monitoring identifier, and check value. As described above, after receiving the detection signal, the processing module adds 1 to the serial number of the previous detection operation to obtain the serial number of the current detection operation. Next, the processing module generates a random code based on the serial number of the current detection operation and executes a hash algorithm to obtain first data. Next, the processing module groups the first data based on a 20-byte array to obtain second data including two arrays. Next, the processing module executes a cyclic redundancy check algorithm based on the second data to obtain third data, which is 2 bytes of data. Finally, the processing module executes an XOR algorithm based on the third data to obtain a 1-byte check value. Step S53: The processing module periodically transmits a beacon signal to the lighting device several times, and enters a sleep state after the transmission of the beacon signal is completed. For example, the processing module may transmit a beacon signal to the lighting device every 200 ms, and repeat the above transmission five times. After that, the processing module may enter a sleep state. Step S54: The lighting device activates other lighting devices in the lighting device group according to the beacon signal, or discards the beacon signal. As described above, if the lighting device determines that the serial number of the received beacon signal matches the serial number of the last received beacon signal, the lighting device discards the beacon signal. If the lighting device determines that the serial number of the received beacon signal does not match the serial number of the last received beacon signal, the lighting device analyzes the check value to confirm whether it is valid. The lighting device calculates the check value in the same way (random code algorithm + parity grouping step + cyclic redundancy check algorithm + XOR algorithm). If the check value calculated by the lighting device matches the check value of the beacon signal, the beacon signal is valid. Finally, the lighting device generates a group message according to the group identifier of the beacon signal and broadcasts the group message to other lighting devices in the same group based on the Bluetooth mesh protocol to simultaneously activate these lighting devices.

[0049] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or variations made based on the control method of the monitoring device of this embodiment should still fall within the scope of protection of the present invention.

[0050] Although the steps of the methods described herein are shown and described in a particular order, the order of operations of each method may be changed, some steps may be performed in reverse order or simultaneously with other steps, and in other embodiments, different steps may be performed intermittently and / or alternately.

[0051] In summary, according to the first, second, and third embodiments of the present invention, a monitoring device includes a beacon module, a detection module, and a processing module. The detection module performs a detection operation, detects a moving object, and generates a detection signal. The processing module generates a beacon signal after receiving the detection signal and transmits the beacon signal to a lighting device via the beacon module. The processing module generates a check value based on a serial number, a group identifier, a monitoring identifier, and a random code representing the detection operation, generates a beacon signal including the serial number, the group identifier, the monitoring identifier, and the check value, and causes the lighting device to operate according to the beacon signal. Here, the lighting device performs a verification process based on the beacon signal and, after confirming that the beacon signal is valid, sends a group message to other lighting devices belonging to the same group as the lighting device, causing these lighting devices to enter an awake state. After completing the transmission of the beacon signal, the processing module enters a sleep state to reduce power consumption. From the above, it can be seen that the processing module of the monitoring device can enter a sleep state after completing the transmission of the beacon signal, thereby significantly reducing power consumption and battery consumption. Therefore, users do not need to frequently maintain the monitoring device, which makes the maintenance of the monitoring device more convenient and can meet the needs of practical applications.

[0052] Furthermore, based on the first and second embodiments of the present invention, the monitoring device can achieve the lighting device group control function through a one-way beacon signal communication mechanism, and does not need to receive signals from the Bluetooth mesh, eliminating the need for a signal reception function. This further reduces the power consumption of the monitoring device and reduces battery consumption. Therefore, the monitoring device can meet the needs of practical applications.

[0053] Furthermore, based on the first and second embodiments of the present invention, the monitoring device can achieve the lighting device group control function through a one-way beacon signal communication mechanism, and does not need to participate in the periodic update operation (such as key update) of the Bluetooth mesh. This significantly reduces the power consumption of the monitoring device, further reducing battery consumption. This makes the maintenance of the monitoring device more convenient and meets the needs of practical applications.
