Description

Technical Field

[0001] This application relates to the field of data communication technology, and more specifically, to a communication method and apparatus based on ad hoc wireless devices. Background Technology

[0002] However, traditional battery-powered wireless devices, in order to extend product lifespan, set relatively long wake-up intervals. While this reduces power consumption, it sacrifices real-time communication response. This fails to meet the needs of applications with short response time requirements, such as devices linked to alarms, where the linked device needs to act within seconds of an alarm. It's impossible to balance product lifespan and real-time communication; either the communication response time is too long, or the product lifespan is too short. How to improve product lifespan while maintaining a short communication response time has become one of the many problems that those skilled in the art need to solve. Summary of the Invention

[0003] The purpose of this application is to overcome the shortcomings of existing technologies and provide a communication method and apparatus for self-organizing wireless devices. By detecting the preamble, the power consumption of the device during normal operation is greatly reduced. By adding a return code time parameter to the data frame, the power consumption during communication is greatly reduced, thus significantly extending the lifespan of the device. It also meets the requirements of reliability in ultra-low power consumption scenarios.

[0004] The objective of this application is achieved through the following technical solution:

[0005] In a first aspect, this application proposes a communication method based on ad hoc wireless devices, the method comprising:

[0006] The sending end continuously transmits data frames, and the data frames include the return code time of the receiving end;

[0007] The receiving end cyclically checks for a preamble according to the wake-up cycle. The preamble is used to indicate whether there is data to be received.

[0008] If the preamble is not detected, the system enters a low-power sleep state.

[0009] If the preamble is detected, the data frame is received, and after receiving the data frame, the system enters a low-power sleep state and waits for the return code time to pass before returning the code.

[0010] In one possible implementation, the duration for which the sending end transmits the information frame is longer than the wake-up period of the receiving end.

[0011] In one possible implementation, the receiver is pre-set with a preamble detection period, which represents the interval between preamble detections by the receiver.

[0012] In one possible implementation, the receiver is further preset with a time required to detect the preamble, the time required to detect the preamble representing the duration of the receiver's detection of the preamble.

[0013] In one possible implementation, the receiving end is pre-set with a wake-up duration, which represents the time it takes for the sending end to send one data frame.

[0014] In one possible implementation, the preamble detection period is shorter than the time required to detect the preamble.

[0015] In one possible implementation, the steps prior to continuously transmitting data frames via the sending end further include:

[0016] The radio frequency parameters and communication frame format of the transmitting end and the receiving end are configured in advance. The data frame also includes a preamble, application data and a check bit.

[0017] Secondly, this application proposes a communication device based on an ad hoc wireless network, the device comprising:

[0018] A sending module is used to continuously send data frames through a sending end, wherein the data frames include the response time of the receiving end;

[0019] The detection module is used to cyclically detect whether there is a preamble by the receiving end according to the wake-up cycle. The preamble is used to indicate whether there is data to be received.

[0020] A sleep module is used to enter a low-power sleep state if the preamble is not detected.

[0021] The receiving module is configured to receive the data frame if the preamble is detected, and after receiving the data frame, enter a low-power sleep state and wait for the return code time to pass before returning the code.

[0022] Thirdly, this application also proposes a computer device comprising a processor and a memory, wherein the memory stores a computer program, which is loaded and executed by the processor to implement the communication method based on an ad hoc wireless device as described in any of the first aspects.

[0023] Fourthly, this application also proposes a computer-readable storage medium storing a computer program that is loaded and executed by a processor to implement the communication method based on an ad hoc wireless device as described in any of the first aspects.

[0024] The main solution and its various further alternatives described above can be freely combined to form multiple solutions, all of which are solutions that can be adopted and are claimed in this application; furthermore, the (non-conflicting alternatives) can also be freely combined with each other and with other alternatives. Those skilled in the art, after understanding the solution of this application, will realize from the prior art and common general knowledge that there are many combinations, all of which are technical solutions to be protected by this application, and will not be exhaustively listed here.

[0025] This application discloses a communication method and apparatus for ad hoc wireless devices. The method includes: continuously transmitting data frames through a transmitter; cyclically detecting the presence of a preamble at a receiver according to a wake-up cycle; determining whether data needs to be received based on the preamble; and entering a low-power sleep state if no preamble is detected. If a preamble is detected, receiving data frames; and entering a low-power sleep state after receiving the data frames, waiting for the echo time to elapse before echoing the data frames. By detecting the preamble, the power consumption of the device during normal operation is greatly reduced. By adding an echo time parameter to the data frames, the power consumption during communication is significantly reduced, resulting in a substantial increase in the device's lifespan and meeting the requirements of reliability in ultra-low power scenarios.

[0029] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be noted that, unless otherwise specified, the following embodiments and features in the embodiments can be combined with each other.

[0030] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0031] In existing technologies, traditional battery-powered wireless devices often have long wake-up intervals to extend product lifespan. While this reduces power consumption, it sacrifices real-time communication response. This fails to meet the needs of applications with short response time requirements, such as devices linked to alarms, where the linked device needs to act within seconds of an alarm. It's impossible to balance product lifespan and real-time communication; either the communication response time is too long, or the product lifespan is too short. How to improve product lifespan while maintaining a short communication response time has become one of the many problems that those skilled in the art need to solve.

[0032] Therefore, to address the challenge of extending product lifespan while maintaining short communication response times in battery-powered wireless device applications—that is, reducing power consumption and avoiding the inconvenience of frequent battery replacements throughout the product's lifespan—this application proposes a communication method and apparatus for ad hoc wireless devices. By detecting preambles, the power consumption during normal operation is significantly reduced. Furthermore, by adding a response time parameter to the data frame, power consumption during communication is greatly reduced, resulting in a substantial increase in device lifespan. This method also achieves reliability in ultra-low power consumption scenarios, which will be described in detail below.

[0033] Please refer to Figure 1 , Figure 1 A flowchart illustrating a communication method based on an ad hoc wireless network according to an embodiment of this application is shown. The communication method includes the following steps:

[0034] S100: Continuously send data frames through the sending end.

[0035] S200: The receiving end continuously checks for a preamble according to the wake-up cycle.

[0036] If no preamble is detected, the S300 enters a low-power sleep state.

[0037] S400: If a preamble is detected, a data frame is received. After receiving the data frame, the system enters a low-power sleep state and waits for the code return time to complete the code return.

[0038] The data frame includes the receiver's response time. The preamble indicates whether data needs to be received. The receiver can use low-power devices to reduce power consumption. When data needs to be sent, the transmitter repeatedly sends the data frame continuously. The receiver checks for a preamble in the air according to a wake-up cycle. If no preamble is detected, it immediately enters sleep mode. If a preamble is detected, it receives the complete data frame. After receiving the data frame, it also enters sleep mode, waking up after the response time to complete the response.

[0039] Since the battery-powered wireless device, including the receiver and transmitter of this application, does not require communication most of the time during the entire communication process, the receiver only consumes significant power when detecting the preamble and receiving data frames. The power consumption of periodically detecting the preamble accounts for a large portion of the device's power consumption. Furthermore, the power consumption of detecting a single preamble is far lower than the power consumption of directly detecting the entire data frame. Therefore, the embodiments of this application can greatly reduce the power consumption of the battery-powered wireless device during normal operation, thereby extending the device's lifespan.

[0040] When the sending end repeatedly sends the information frame to be sent in a continuous and uninterrupted manner, the duration of the transmission must be slightly longer than the wake-up period of the receiving device.

[0041] Optionally, before the sending end continuously transmits data frames, it also includes:

[0042] The radio frequency parameters and communication frame format of the transmitting and receiving ends are configured in advance. The data frame also includes a preamble, application data, and a check bit.

[0043] After pre-configuring the radio frequency parameters and communication frame format, this application also proposes another possible implementation method, which consists of the following steps:

[0044] Step S1: Configure the various cycles of the receiver, including the wake-up cycle T1, wake-up duration T2, preamble detection cycle T3, and preamble detection time T4. The wake-up cycle T1 indicates how often the receiver wakes up; for example, if the receiver wakes up every 5 seconds, T1 = 5 seconds. The wake-up duration T2 indicates the transmission time of one data frame by the transmitter; for example, if the transmitter takes 4.8 ms to send one data frame, then T2 = 4.8 ms. The preamble detection cycle T3 indicates the interval at which the receiver detects the preamble; for example, if the receiver detects the preamble every 900 µs during the wake-up period, then T3 = 900 µs. The preamble detection time T4 indicates the duration of the receiver's preamble detection; for example, if the receiver's preamble detection time is 100 µs, then T4 = 100 µs. Please refer to... Figure 2 and Figure 3 , Figure 2 This illustration shows a schematic diagram of the periodic wake-up proposed in an embodiment of this application. Figure 3 This diagram illustrates a wake-up periodic detection preamble proposed in an embodiment of this application. Figure 2 The wake-up period at the receiving end is T1, and within the wake-up period T1 there is a wake-up duration T2. Figure 3The wake-up duration T2 includes multiple preamble detection cycles T3, and each preamble detection cycle T3 contains the time T4 required to detect the preamble.

[0045] Step S2: The sending end pre-configures the duration T5 of the transmitted information frame. This duration is greater than the wake-up period T1 of the receiving end. For example, if the wake-up period T1 of the receiving end is 5s, then the value of T5 can be slightly greater than 5s.

[0046] Step S3: The receiving end wakes up once every wake-up period T1, and detects the preamble during the preamble detection period T3 within the wake-up duration T2. ​​The preamble detection period T3 is less than the time T4 required to detect the preamble.

[0047] Step S4: If a preamble is detected during the wake-up period, the system continues to receive the data frame until the data frame is fully received. After the data frame is received, the system immediately enters a sleep state. The sleep time is equal to the return code time parameter in the data frame. Once the sleep time ends (i.e., the return code time has arrived), the service data is sent back to the sending end.

[0048] Step S5: If no preamble is detected during the wake-up period, the system will immediately enter a sleep state after the wake-up time ends, waiting for the next wake-up and detection.

[0049] Step S6: Repeat steps S3-S5.

[0050] Therefore, this application discloses a communication method for ad hoc wireless devices. The transmitting end continuously sends data frames, while the receiving end cyclically checks for a preamble according to a wake-up cycle. The preamble determines whether data needs to be received. If no preamble is detected, the device enters a low-power sleep state. If a preamble is detected, the device receives data frames and then enters a low-power sleep state, waiting for the echo time to elapse before responding. By detecting the preamble, the power consumption during normal operation is significantly reduced. Furthermore, by adding an echo time parameter to the data frames, the power consumption during communication is greatly reduced, significantly extending the device's lifespan and meeting the requirements of reliability in ultra-low-power scenarios.
