Detailed Description
The present disclosure is described below based on examples, but the present disclosure is not limited to only these examples. In the following detailed description of the present disclosure, certain specific details are set forth. It will be apparent to those skilled in the art that the present disclosure may be practiced without these specific details. Well-known methods, procedures, components and circuits have not been described in detail so as not to obscure the present disclosure.
Further, those of ordinary skill in the art will appreciate that the drawings provided herein are for illustrative purposes and are not necessarily drawn to scale.
Unless the context clearly requires otherwise, throughout this specification, the words "comprise", "comprising", and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is, what is meant is "including, but not limited to".
In the description of the present disclosure, it is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In addition, in the description of the present disclosure, "a plurality" means two or more unless otherwise specified.
Fig. 1 is a schematic diagram of a wireless communication system of an embodiment of the present invention. As shown in fig. 1, the wireless communication system of the embodiment of the present invention includes a plurality of wireless communication apparatuses and a wireless channel 2. The present embodiment is described by taking four wireless communication apparatuses 1a to 1d as an example. The wireless communication device is used for wireless communication, and the wireless communication device can be a wireless signal receiving end or a wireless signal sending end. The wireless channel 2 is a path between a receiving end and a transmitting end of a wireless communication device in wireless communication, and for radio waves, transmitted from the transmitting end to the receiving end, there is no physical connection therebetween.
In the present embodiment, a plurality of identical wireless communication apparatuses in the same application scenario generally use the same wireless channel for communication, and thus data collision is likely to occur when communication is performed between the plurality of wireless communication apparatuses.
In one embodiment, the wireless communication device may be a bluetooth beacon apparatus, which is particularly applicable to store card punching, location-assisted positioning, and the like.
Specifically, each bluetooth beacon device has a unique identifier, and the bluetooth beacon device may transmit a bluetooth signal (data packet) in a broadcast manner, where the data packet includes the identifier of the bluetooth beacon device. When a terminal device (e.g., a mobile phone) performs a scanning operation, it receives a broadcasted data packet. When a broadcasted data packet is Received, the Bluetooth beacon device from which the data packet comes is determined according to the identity in the data packet, and the RSSI (Received Signal Strength Indication) value, so that the card punching or positioning to a store is realized through an application program or a server installed on the terminal equipment.
However, the coverage area of the bluetooth beacon device is limited, and if the area of the usage scene is too large, a plurality of bluetooth beacon devices are usually required to be arranged. Since a plurality of identical bluetooth beacon apparatuses generally communicate using the same channel, data collision is likely to occur when a plurality of bluetooth beacon apparatuses communicate with each other.
Therefore, the embodiment of the invention provides the electronic equipment to reduce the probability of channel collision of the communication system.
Specifically, fig. 2 is a schematic diagram of an electronic device of an embodiment of the present invention. As shown in fig. 2, the electronic device of the embodiment of the present invention is a wireless communication device, and includes a controller, a communication component 13, a light sensor 14, and a wireless communication unit 15. Wherein the controller comprises at least one processor 11 and a memory 12. The wireless communication unit 15 is performing wireless communication under the control of the processor 11. The communication assembly 13 is communicatively coupled to the scanning device and receives and transmits data under the control of the processor 11. The light sensor 14 is controlled by the processor 11 to detect the intensity of ambient light.
Specifically, the electronic device includes: one or more processors 11 and memory 12,
in fig. 2, one processor 11 is taken as an example. The processor 11 and the memory 12 may be connected by a bus or other means, and fig. 2 illustrates the connection by the bus as an example. Memory 12, which is a non-volatile computer-readable storage medium, may be used to store non-volatile software programs, non-volatile computer-executable programs, and modules. The processor 11 executes various functional applications of the device and data processing, i.e., implements the control method of the embodiment of the present invention, by executing nonvolatile software programs, instructions, and modules stored in the memory 12.
The memory 12 may include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required for at least one function; the storage data area may store a list of options, etc. Further, the memory 12 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other non-volatile solid state storage device.

Examples of such networks include, but are not limited to, the internet, intranets, local area networks, mobile communication networks, and combinations thereof.

The product can execute the method provided by the embodiment of the application, has corresponding functional modules and beneficial effects of the execution method, does not have detailed technical details in the embodiment, and can refer to the control method provided by the embodiment of the invention.
Fig. 3 is a flowchart of a control method of an embodiment of the present invention. As shown in fig. 3, the control method according to the embodiment of the present invention includes the following steps:
and S100, controlling the light sensor to continuously detect the intensity of the ambient light.
In the present embodiment, the processor 11 controls the light sensor 14 to continuously detect the ambient light intensity.
In this embodiment, the wireless communication device continuously acquires the ambient light intensity through the light sensor 14. The optical sensor is a device which can sensitively detect light energy from ultraviolet light to infrared light and convert the light energy into an electric signal, and mainly comprises a photosensitive element.
Alternatively, the continuous acquisition of the ambient light intensity is to control the light sensor 14 to periodically detect the ambient light intensity for a small detection time period.
And S200, determining a synchronous time point according to the ambient light intensity.
In this embodiment, the processor 11 determines the synchronization time point according to the ambient light intensity.
Specifically, fig. 4 is a flowchart of determining a synchronization time point according to an embodiment of the present invention. As shown in fig. 4, determining the synchronization time point according to the ambient light intensity includes the steps of:
step S210, a light intensity threshold is acquired.
In the present embodiment, the light intensity threshold is set according to the actual application scenario. For example, the light intensity threshold Eref may be set to any value within the interval (0, E2-E1) with the ambient light intensity when the lighting is not turned on in the scene as the first value E1 and the ambient light intensity after the lighting as the second value E2.
Further, due to other factors, it may happen that the ambient light intensity of only a part of the area within the scene changes slightly, and thus, the light intensity threshold of the embodiment of the present invention may not be set too small, and it may happen that the wireless communication device of only a part of the area performs time synchronization when the light intensity threshold is too small. Meanwhile, the light intensity threshold value may not be set too large, and if the light intensity threshold value is too large, it may happen that the variation of the light intensity threshold value in a partial area does not exceed the light intensity threshold value, resulting in time synchronization of only a part of wireless communication devices. Specifically, the change of the light intensity of the area where each wireless communication device is located during the turning on and turning off of the lamp in a scene can be counted, and the light intensity threshold value is set according to the counting result, so that each wireless communication device can perform time synchronization during the turning on and turning off of the lamp.
Step S220, calculating and obtaining the variation of the ambient light intensity according to the ambient light intensities at the current time point and the previous time point.
In the present embodiment, the ambient light intensity E at the current time point is acquired iAnd the intensity of the ambient light at the previous time pointDegree E i-1Calculating the ambient light intensity E iAnd E i-1The absolute value of the difference value Δ E is the variation of the ambient light intensity.
Step S230, determining a current time point corresponding to the time when the variation of the ambient light intensity is higher than the light intensity threshold as a synchronization time point.
In this embodiment, the variation of the ambient light intensity is compared with a light intensity threshold, and in response to the variation of the ambient light intensity being higher than the light intensity threshold, the corresponding current time point is determined as the synchronization time point.
Specifically, fig. 5 is a schematic diagram of the variation of the ambient light intensity according to the embodiment of the present invention. Fig. 5 shows the amount of change in the ambient light intensity over a period of time. Wherein the abscissa t represents time, and t1-t12 represent twelve time points. The ordinate Δ E represents the ambient light intensity and Eref represents the light intensity threshold.
In the present embodiment, the time difference between every two time points may be set according to the actual application scenario, for example, the time difference may be 1 second.
In the present embodiment, the light intensity threshold value Eref is set according to an actual application scenario.
As shown in fig. 5, the light intensity changes at time points t4, t7, and t 10. Here, at time points t4 and t7, the light intensity variation is large and exceeds the light intensity threshold Eref, so t4 and t7 are synchronous time points. At the time point t10, the light intensity variation amount is small and does not exceed the light intensity threshold Eref, and therefore, t10 is not the synchronization time point.
Thereby, the synchronization time point may be determined from a change in the ambient light intensity, for example from a switching behavior. Meanwhile, by setting the light intensity threshold, time synchronization is not performed under the condition that light changes weakly, and errors caused by other interference factors to the light are reduced.
And step S300, triggering the wireless communication unit to carry out time synchronization at the synchronization time point.
In an alternative implementation, triggering the wireless communication unit to perform time synchronization at the synchronization time point is to calibrate the time of the wireless communication unit so that the time is synchronized.
Specifically, the time of any one of the plurality of wireless communication apparatuses may be taken as a standard time, and the times of the other wireless communication apparatuses may be synchronized according to the standard time so that the times of the plurality of wireless communication apparatuses coincide.
In another alternative implementation, the wireless communication unit is triggered to perform time synchronization at the synchronization time point, the timing is cleared, and the re-timing is started so as to synchronize the time.
Because the light intensity in different areas at the same moment in the same scene is not very different often, the propagation speed of light is faster simultaneously, so that when the action of turning on or off the lamp is carried out, the light intensity in different areas jumps simultaneously, and then all wireless communication equipment is triggered to carry out time synchronization, and the time of a plurality of wireless communication equipment at the synchronous time point is consistent.
And step S400, controlling the wireless communication unit to communicate at a preset time.
In the present embodiment, after time synchronization of the wireless communication device, the wireless communication unit is controlled to perform communication at a predetermined time.
In one embodiment, the wireless communication unit may be a wireless broadcast unit, such as a bluetooth module in a bluetooth beacon device. After the plurality of Bluetooth beacon devices are time-synchronized by the method, each Bluetooth beacon device can be preset to send the Bluetooth beacon in the own time gap, so that the Bluetooth beacon devices are ensured not to generate channel conflict.
Further, the wireless broadcasting unit is a bluetooth module, and controls the bluetooth module to send a bluetooth signal in a broadcast manner within a predetermined time period, wherein the bluetooth signal includes an identification of the bluetooth module. Therefore, the terminal equipment determines which Bluetooth beacon device the data packet comes from according to the received broadcasted data packet, and the RSSI value, and further realizes the card punching or positioning to a store through an application program or a server installed on the terminal equipment.
Furthermore, the Bluetooth module is a low-power Bluetooth module, so that power consumption can be reduced, and cruising ability can be improved.
In another embodiment, the wireless communication unit may be a wireless receiving unit. When both the transceiver devices of the wireless communication system cannot synchronize with each other, the wireless receiving unit needs to keep the receiving power on all the time so as not to miss signals of the wireless transmitting device. After the plurality of Bluetooth beacon devices are time-synchronized by the method, the wireless transmitting unit and the corresponding wireless receiving unit can be set to communicate in the same time zone, and the wireless transmitting unit and the corresponding wireless receiving unit are controlled to be in a low power consumption mode or a closed state in other time periods, so that the power consumption of the wireless receiving unit can be reduced.
Further, the wireless receiving unit is a bluetooth module, and controls the bluetooth module to receive the bluetooth signal within a predetermined time period.
Further, the bluetooth module is a low power consumption bluetooth module, and thus, power consumption can be further reduced.
Further, the operating times of the plurality of wireless communication apparatuses in the same scene may be set in advance, for example, the operating time of the wireless communication apparatus 1a is set to (T1-T2), the operating time of the wireless communication apparatus 1b is set to (T2-T3), the operating time of the wireless communication apparatus 1c is set to (T3-T4), and the operating time of the wireless communication apparatus 1d is set to (T4-T5).
Therefore, the wireless communication devices in the same scene can be controlled to work in different time intervals so as to reduce channel collision.
The present embodiment continuously detects the intensity of the ambient light by controlling the light sensor, and determines the synchronization time point according to the intensity of the ambient light to trigger the wireless communication device to perform time synchronization at the synchronization time point, and transmits a signal at a predetermined time. Thus, a plurality of wireless communication apparatuses in the same scene can be synchronized in time well, and signals can be transmitted at a predetermined time, thereby reducing the occurrence of communication systems.
