Description

Technical Field

[0001] This application relates to the field of street light control technology, and in particular to a fog light synchronization control method, a main control chip, a fog light, and a fog light system. Background Technology

[0002] Currently, synchronized fog lights on highways can be controlled synchronously using MCUs (Microcontroller Units) and wireless communication modules. However, this method suffers from high power consumption, high cost, and limited range. It requires an additional host to broadcast a synchronization signal to maintain synchronization. For long-distance installations, multiple hosts are needed for relaying, which not only increases costs but also makes on-site installation and debugging cumbersome.

[0003] Meanwhile, synchronized fog lights can also use GPS (Global Positioning System), which is not limited by distance, but requires a good satellite signal, is relatively expensive, and is limited to locations with satellite coverage. Summary of the Invention

[0004] In view of this, embodiments of this application provide a fog light synchronization control method, a main control chip, a fog light, and a fog light system to solve the problems of high cost caused by the need for a host to relay or the use of GPS communication in the prior art for fog light synchronization control.

[0005] A first aspect of this application provides a fog light synchronization control method applied to a fog light system. The fog light system includes at least two fog lights, each fog light includes a signal transceiver module, and each signal transceiver module receives and transmits a synchronization signal through a signal channel. The method includes:

[0006] In response to receiving a synchronization signal, the fog lights are controlled to light up and turn off according to a predetermined on / off control logic, and the preset first synchronization cycle is changed to a second synchronization cycle. Both the first and second synchronization cycles are the transmission cycle from receiving the synchronization signal to sending the synchronization signal, but the duration of the first synchronization cycle is different from that of the second synchronization cycle. In response to the duration of the second synchronization cycle, a synchronization signal is sent, and the fog lights are controlled to light up and turn off again according to the predetermined on / off control logic, changing the second synchronization cycle back to the first synchronization cycle.

[0007] In one possible implementation, in response to receiving a synchronization signal, the fog lights are controlled to illuminate and extinguish according to a predetermined on / off control logic, and before the preset first synchronization cycle is changed to a second synchronization cycle, the following is included: In response to the duration of the first synchronization cycle, a synchronization signal is sent, and the fog lights are controlled to light up and turn off again according to the predetermined on / off control logic.

[0008] In one possible implementation, the fog lights are controlled to illuminate and extinguish according to a predetermined on / off control logic, including: According to the on / off control cycle, the fog lights are periodically controlled to illuminate for a first preset duration and then turn off for a second preset duration.

[0009] In one possible implementation, the duration of the second synchronization cycle and the duration of the first synchronization cycle are both integer multiples of the duration of the on / off control cycle, and the duration of the second synchronization cycle is less than the duration of the first synchronization cycle.

[0010] In one possible implementation, the fog lights are periodically controlled sequentially for a first preset duration of illumination and a second preset duration of extinguishing, according to the illumination-off control cycle, including: Within each on / off control cycle, the fog lights are controlled sequentially for a first preset duration of illumination and a second preset duration of extinguishing by setting a time base using a timer and counting with a counter.

[0011] In one possible implementation, the fog light synchronization control method further includes at least one of the following: In response to a color control signal from an external device, the fog lights are controlled to adjust their emission color based on the color control signal. In response to a brightness control signal from an external device, the fog lights are controlled to adjust their brightness based on the brightness control signal.

[0012] The second aspect of this application provides a master control chip, including: a signal transceiver module, a memory, a processor, and a computer program stored in the memory and executable on the processor. The signal transceiver module and the memory are both electrically connected to the processor. When the processor executes the computer program, it implements the steps of the method of the first aspect.

[0013] A third aspect of this application provides a fog light, including: a fog light body, a bulb connected to the fog light body, and a main control chip as described in the second aspect; the main control chip is disposed within the fog light body.

[0014] In one possible implementation, the fog lights also include: a solar panel; The solar panel is connected to the fog light body and is used to power the fog light.

[0015] A fourth aspect of this application provides a fog light system, including at least two fog lights as described in the third aspect.

[0016] Compared with the prior art, the embodiments of this application have at least the following technical effects: The fog light synchronization control method of the first aspect of this application can be applied to a fog light system, which includes at least two fog lights, each fog light including a signal transceiver module. Since the fog lights receive and send synchronization signals through a signal channel of the signal transceiver module, it is necessary to avoid simultaneous reception and transmission of synchronization signals. The duration of the first synchronization period in this application is different from the duration of the second synchronization period. By receiving a synchronization signal, the initial first synchronization period is changed to the second synchronization period, and the transmission period is changed. When the duration of the second synchronization period is reached, a synchronization signal is sent, and then the second synchronization period is changed back to the first synchronization period, thus staggering the timing of receiving and sending synchronization signals. When each fog light receives and sends a synchronization signal, it controls the fog light to light up and turn off according to a predetermined on / off control logic. After each fog light is powered on, the fog light synchronization control method of this application will gradually maintain synchronization. Therefore, this application embodiment is cleverly designed in software, achieving infinite cascading synchronization without a host computer by sending and receiving synchronization signals between fog lights. This greatly saves hardware costs, and the installation distance is not limited, covering the entire length of a highway.

[0017] It is understood that the beneficial effects of the second to fourth aspects mentioned above can be found in the relevant descriptions in the first aspect mentioned above, and will not be repeated here. Attached Figure Description

It should be noted that the following embodiments can be referenced, borrowed, or combined with each other, and the same terms, similar features, and similar implementation steps in different embodiments will not be described again.

[0029] See Figure 1 As shown in the diagram, this application provides a schematic diagram of a fog light system. The fog light system includes at least two fog lights. Figure 1 As shown, taking a fog light system comprising three fog lights as an example, the fog light system includes a first fog light 10, a second fog light 20, and a third fog light 30. The first fog light 10, the second fog light 20, and the third fog light 30 are communicatively connected. In practical applications, more fog lights may be installed as needed.

[0030] See Figure 1 As shown, each fog light includes a main control chip 11, and the main control chip 11 also includes a signal transceiver module 111. The fog lights send and receive synchronization signals through the signal transceiver module 111. Each signal transceiver module 111 receives and sends synchronization signals through a signal channel.

[0031] Optionally, the fog lights are wirelessly connected via a signal transceiver module 111.

[0032] As an example, the signal transceiver module 111 includes a radio frequency (RF) section for transmitting wireless signals. RF stands for Radio Frequency, which refers to electromagnetic frequencies that can be radiated into space, with a frequency range from 300 kHz to 300 GHz.

[0033] This application provides a fog light, including: a fog light body, a bulb connected to the fog light body, and a main control chip 11 according to this application embodiment; the main control chip 11 is disposed in the fog light body.

[0034] Alternatively, the main control chip 11 can use a SOC (System on Chip), which integrates the MCU (Micro Control Unit) and the radio frequency part into a single chip, greatly saving hardware costs and reducing power consumption.

[0035] In some embodiments, the fog light further includes a solar panel. The solar panel is connected to the fog light body and is used to power the fog light.

[0036] The fog lights in this embodiment can be powered by solar panels, further saving energy.

[0037] The main control chip 11 in this application embodiment can implement the fog light synchronization control method of this application embodiment. For details of the fog light synchronization control method, please refer to the following description.

[0038] See Figure 2 As shown, this application embodiment provides a flowchart of a fog light synchronization control method. The fog light synchronization control method is applied to a fog light system, which includes at least two fog lights. Each fog light includes a signal transceiver module 111, and each signal transceiver module 111 receives and transmits synchronization signals through a signal channel. Figure 2 As shown, the fog light synchronization control method of this application embodiment includes steps S201 to S202.

[0039] S201. In response to receiving the synchronization signal, the fog lights are controlled to light up and turn off according to the predetermined on / off control logic, and the preset first synchronization period is changed to the second synchronization period. Both the first synchronization period and the second synchronization period are the transmission period from receiving the synchronization signal to sending the synchronization signal, and the duration of the first synchronization period is different from the duration of the second synchronization period.

[0040] In practical applications, each fog light is powered on but not synchronously, requiring synchronization control through the fog light synchronization control method of this application embodiment.

[0041] In some embodiments, in response to receiving a synchronization signal, controlling the fog lights to illuminate and extinguish according to a predetermined illumination / extinguishing control logic, and before changing a preset first synchronization period to a second synchronization period, the following are included: In response to the duration of the first synchronization cycle, a synchronization signal is sent, and the fog lights are controlled to light up and turn off again according to the predetermined on / off control logic.

[0042] The initial default synchronization cycle for fog lights is the first synchronization cycle. For example, if a fog light is powered on and does not receive a synchronization signal from another fog light, it will send a synchronization signal and control the fog light to flash periodically after the duration of the first synchronization cycle has elapsed.

[0043] Each fog light in this embodiment can act as both a synchronization initiator and a synchronization recipient, and will automatically switch roles based on the sending and receiving status.

[0044] Each fog light can receive the synchronization signal of another fog light within its signal range.

[0045] In some embodiments, controlling the fog lights to illuminate and extinguish according to a predetermined illumination / extinguishing control logic includes: periodically controlling the fog lights to illuminate for a first preset duration and extinguish for a second preset duration according to an illumination / extinguishing control cycle.

[0046] Optionally, the first preset duration and the second preset duration are the same, and the first preset duration and the second preset duration form the duration of the on / off control cycle.

[0047] S202. In response to the duration of the second synchronization cycle, a synchronization signal is sent, and the fog lights are controlled to light up and turn off again according to the predetermined on / off control logic, changing the second synchronization cycle to the first synchronization cycle.

[0048] In some embodiments, in response to the duration of the second synchronization period, a synchronization signal is sent, and the fog lights are controlled to illuminate and extinguish according to a predetermined illumination / extinguishing control logic. After changing the second synchronization period to the first synchronization period, the process includes: In response to the duration of the first synchronization cycle, a synchronization signal is sent, and the fog lights are controlled to light up and turn off again according to the predetermined on / off control logic.

[0049] Optionally, if no synchronization signal is received in this embodiment of the application, a synchronization signal can be sent when the duration of the first synchronization cycle is reached, and the fog lights can be controlled to light up and turn off again according to the predetermined on / off control logic.

[0050] The fog light synchronization control method of this application embodiment can be applied to a fog light system, which includes at least two fog lights. Each fog light includes a signal transceiver module 111. Since the fog lights receive and send synchronization signals through a signal channel of the signal transceiver module 111, it is necessary to avoid simultaneous reception and transmission of synchronization signals. In this application embodiment, the duration of the first synchronization period is different from the duration of the second synchronization period. By receiving a synchronization signal, the initial first synchronization period is changed to the second synchronization period, and the transmission period is changed. When the duration of the second synchronization period is reached, a synchronization signal is sent, and then the second synchronization period is changed back to the first synchronization period, thus staggering the timing of receiving and sending synchronization signals. When each fog light receives and sends a synchronization signal, it controls the fog light to light up and turn off according to a predetermined on / off control logic. In this way, after each fog light is powered on, the fog light synchronization control method of this application embodiment will gradually maintain synchronization.

[0051] Therefore, the fog light synchronization control method in this application is cleverly designed in software. By sending and receiving synchronization signals between each fog light, infinite cascading synchronization can be achieved without a host, greatly saving hardware costs and not limiting the installation distance, which can cover the entire length of the highway.

[0052] In some embodiments, the duration of the second synchronization period and the duration of the first synchronization period are both integer multiples of the duration of the on / off control period, and the duration of the second synchronization period is less than the duration of the first synchronization period.

[0053] Optionally, the duration of the second synchronization period can be half the duration of the first synchronization period.

[0054] As an example, the duration of the on / off control cycle can be 1 second, the duration of the first synchronization cycle can be 10 seconds, and the duration of the second synchronization cycle can be 5 seconds.

[0055] Optionally, the first preset duration can be 500ms, and the second preset duration can be 500ms.

[0056] In some embodiments, according to a lighting control cycle, the fog lights are periodically controlled to illuminate for a first preset duration and then extinguish for a second preset duration, including: Within each on / off control cycle, the fog lights are controlled sequentially for a first preset duration of illumination and a second preset duration of extinguishing by setting a time base using a timer and counting with a counter.

[0057] Optionally, controlling the fog lights to illuminate and extinguish according to the predetermined illumination control logic includes: resetting the counter to zero and restarting the counting.

[0058] Optionally, the main control chip 11 uses the MCU hardware timer to generate a 1ms time base for precise period calculation. 1s corresponds to 1000 counter counts.

[0059] As an example, the software design of this application embodiment adopts a synchronization period halving strategy, that is, the duration of the first synchronization period is T, the duration of the second synchronization period is T / 2, and the synchronization signal can be a synchronization data frame.

[0060] Taking fog light A as an example, the default transmission period is T. If fog light A does not receive synchronization data frames from surrounding fog lights, after the transmission period is T, fog light A will send out synchronization data frames. The transmission period of fog light X that receives the synchronization data frames will change from T to T / 2, and they will remain synchronized.

[0061] Fog light X will send a synchronization data frame at time T / 2, and the sending period will change to T. At this time, fog light A receives the synchronization data frame, and the sending period changes from T to T / 2. This cycle continues and the fog lights will gradually become synchronized.

[0062] In some embodiments, the fog light synchronization control method further includes at least one of the following; In response to a color control signal from an external device, the fog lights are controlled to adjust their emission color based on the color control signal. In response to a brightness control signal from an external device, the fog lights are controlled to adjust their brightness based on the brightness control signal.

[0063] Optionally, the external device can be a remote control. In this embodiment, the color and / or brightness can be adjusted under the control of the remote control. Red can be used as a warning sign, and yellow can be used in foggy weather.

[0064] Based on the above technical solution, the embodiments of this application further describe the functions of the main control chip 11.

[0065] The main control chip 11 is used to respond to the received synchronization signal, control the fog lights to light up and turn off according to the predetermined on / off control logic, and change the preset first synchronization period to the second synchronization period. Both the first synchronization period and the second synchronization period are the transmission period from receiving the synchronization signal to sending the synchronization signal, and the duration of the first synchronization period is different from that of the second synchronization period. In response to the arrival of the second synchronization period, a synchronization signal is sent, and the fog lights are controlled to light up and turn off again according to the predetermined on / off control logic, and the second synchronization period is changed back to the first synchronization period.

[0066] Optionally, the main control chip 11 is used to send a synchronization signal in response to the duration of the first synchronization cycle, and to control the fog lights to light up and turn off again according to the predetermined on / off control logic.

[0067] Optionally, the main control chip 11 is used to periodically control the fog light to illuminate for a first preset duration and to extinguish for a second preset duration according to the on / off control cycle.

[0068] Optionally, the main control chip 11 is used to control the fog lights to illuminate for a first preset duration and extinguish for a second preset duration by setting a time base using a timer and counting with a counter in each on / off control cycle.

[0069] Optionally, the main control chip 11 is used to control the fog light to adjust the luminous color based on the color control signal in response to the color control signal of the external device; and / or, to control the fog light to adjust the luminous brightness based on the brightness control signal in response to the brightness control signal of the external device.

[0070] See Figure 3 As shown in the diagram, this application provides a schematic structural diagram of a fog light synchronization control device 300. The fog light synchronization control device 300 is applied to a fog light system, which includes at least two fog lights. Each fog light includes a signal transceiver module 111, and each signal transceiver module 111 receives and transmits synchronization signals through a signal channel. Figure 3 As shown, the fog light synchronization control device 300 includes: a first control module 301 and a second control module 302.

[0071] The first control module 301 is used to respond to the received synchronization signal, control the fog lights to light up and turn off according to the predetermined on / off control logic, and change the preset first synchronization period to the second synchronization period. Both the first synchronization period and the second synchronization period are the transmission period from receiving the synchronization signal to sending the synchronization signal, and the duration of the first synchronization period is different from the duration of the second synchronization period.

[0072] The second control module 302 is used to send a synchronization signal in response to the duration of the second synchronization cycle, and to control the fog lights to light up and turn off according to the predetermined on / off control logic, thereby changing the second synchronization cycle to the first synchronization cycle.

[0073] Optionally, the second control module 302 is used to send a synchronization signal in response to the duration of the first synchronization cycle, and to control the fog lights to light up and turn off again according to the predetermined on / off control logic.

[0074] Optionally, the first control module 301 is used to periodically control the fog lights to illuminate for a first preset duration and extinguish for a second preset duration according to the illumination control cycle.

[0075] Correspondingly, the second control module 302 is used to periodically control the fog lights to illuminate for a first preset duration and extinguish for a second preset duration according to the illumination and extinguishing control cycle.

[0076] The duration of the second synchronization cycle and the duration of the first synchronization cycle are both integer multiples of the duration of the on / off control cycle, and the duration of the second synchronization cycle is less than the duration of the first synchronization cycle.

[0077] Optionally, the first control module 301 is used to control the fog lights to illuminate for a first preset duration and extinguish for a second preset duration by setting a time base using a timer and counting with a counter within each on / off control cycle. Correspondingly, the second control module 302 is used to control the fog lights to illuminate for a first preset duration and extinguish for a second preset duration by setting a time base using a timer and counting with a counter within each on / off control cycle.

[0078] Optionally, the fog light synchronization control device 300 further includes a third control module, which is used to implement at least one of the following: In response to a color control signal from an external device, the fog lights are controlled to adjust their emission color based on the color control signal. In response to a brightness control signal from an external device, the fog lights are controlled to adjust their brightness based on the brightness control signal.

[0079] In applications, the modules in the fog light synchronization control device 300 can be software program modules, or they can be implemented through different logic circuits integrated in the processor, or they can be implemented through multiple distributed processors.

[0081] By applying the embodiments of this application, at least the following beneficial effects can be achieved: The fog light synchronization control device 300 of this application embodiment can be applied to a fog light system, which includes at least two fog lights. Each fog light includes a signal transceiver module 111. Since the fog lights receive and send synchronization signals through a signal channel of the signal transceiver module 111, it is necessary to avoid receiving and sending synchronization signals simultaneously. In this application embodiment, the duration of the first synchronization period is different from the duration of the second synchronization period. By receiving a synchronization signal, the initial first synchronization period is changed to the second synchronization period, and the transmission period is changed. When the duration of the second synchronization period is reached, a synchronization signal is sent, and then the second synchronization period is changed back to the first synchronization period. When each fog light receives and sends a synchronization signal, it controls the fog light to light up and turn off according to a predetermined on / off control logic. In this way, after each fog light is powered on, the fog light synchronization control device 300 of this application embodiment will gradually maintain synchronization.
