Detailed Description
Other advantages and effects of the present application will become apparent to those skilled in the art from the following disclosure, which describes the embodiments of the present application with reference to specific examples. The application may be practiced or carried out in other embodiments that depart from the specific details, and the details of the present description may be modified or varied from the spirit and scope of the present application. It should be noted that the following embodiments and features in the embodiments may be combined with each other without conflict.
All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In the prior art, in order to improve the service life of a product, the traditional battery wireless power supply equipment sets the wake-up interval time of the product longer, so that the power consumption of the product is reduced, but the real-time performance of communication response is sacrificed. Application scenes with short response time requirements, such as equipment linked with an alarm, cannot be met, and when an alarm occurs, the linked equipment needs to act within a few seconds. The service life and the communication instantaneity of the product cannot be considered, or the communication response time is long or the service life of the product is short. How to improve the service life of the product while ensuring a short communication response time is one of the problems that one skilled in the art needs to solve.
Therefore, in order to solve the problem of how to improve the service life of the product under the condition of ensuring short communication response time in the application scene of the wireless equipment powered by the battery, namely, reduce the power consumption of the product and avoid the trouble of frequently replacing the battery in the life cycle of the product. The application provides a communication method and a communication device based on an ad hoc network wireless device, which greatly reduce the power consumption of the device in normal time by detecting a preamble, and greatly reduce the power consumption consumed in the communication period by increasing a code return time parameter in a data frame, so that the service life of the device is greatly prolonged. The characteristics of simultaneously having reliability in the ultra-low power consumption scene are satisfied, and the following detailed description is made.
Referring to fig. 1, fig. 1 shows a flow chart of a communication method based on an ad hoc network wireless device according to an embodiment of the present application, where the communication method includes the following steps:
s100, continuously transmitting data frames through a transmitting end.
S200, detecting whether a preamble exists or not through the receiving end according to the wake-up period in a circulating mode.
And S300, if the preamble is not detected, entering a low-power-consumption dormant state.
And S400, if the preamble is detected, receiving the data frame, entering a low-power-consumption dormant state after receiving the data frame, and waiting for the code returning time to be finished.
The data frame comprises the code returning time of the receiving end, the preamble is used for indicating whether data needs to be received or not, the receiving end can adopt low-power-consumption equipment to reduce the power consumption of products, when the transmitting end needs to transmit the data, the transmitting end repeatedly transmits the data frame to be transmitted currently in a continuous and uninterrupted transmission mode, the receiving end circularly detects whether the preamble exists in the air according to a wake-up period, and if the preamble does not exist, the receiving end immediately enters dormancy waiting. If the preamble is detected, the complete current data frame is received, the dormancy waiting is also carried out after the data frame is received, and the receiving end is awakened to complete the code returning after the code returning time.
Because the battery wireless power supply equipment comprising the receiving end and the sending end does not have communication requirements in the whole communication process, the power consumption of the receiving end is larger only when detecting the preamble and receiving the data frame, and the power consumption of the periodically-detected preamble consumes most of the power consumption of the equipment. The power consumption of detecting the primary preamble is far lower than that of directly detecting the whole data frame, so that the embodiment of the application can greatly reduce the power consumption of the battery wireless power supply equipment in normal times and achieve the purpose of prolonging the service life of the equipment.
When the transmitting end repeatedly transmits the information frame to be transmitted in a continuous and uninterrupted transmission mode, the duration of transmission is required to be slightly longer than the duration of the information frame transmitted by the transmitting end of the wake-up period of the receiving equipment and longer than the wake-up period of the receiving end.
Optionally, before the transmitting end continuously transmits the data frames, the method further includes:
the radio frequency parameters of the transmitting end and the receiving end and the communication frame format are configured in advance, and the data frame also comprises a preamble, application data and check bits.
After the radio frequency parameters and the communication frame format are preconfigured, another possible implementation manner is provided in the embodiment of the present application, which includes the following steps:
step S1, each period of the receiving end is configured, including a wake-up period T1, a wake-up duration T2, a preamble detection period T3, and a time T4 required for detecting the preamble. The wake-up period T1 indicates how often the receiving end wakes up, for example, how often the receiving end 5s wakes up, t1=5s. The wakeup duration T2 represents a transmission time of a frame of data transmitted by the transmitting end, for example, a time of a frame of data transmitted by the transmitting end is 4.8ms, and t2=4.8 ms. The preamble detection period T3 represents an interval time during which the receiving end detects the preamble, for example, the receiving end detects the preamble every 900us during the wake-up period, and t3=900 us. The time T4 required for detecting the preamble indicates the duration of the preamble at the receiving end, for example, the duration of the preamble at the receiving end is 100us once, t4=100 us. Referring to fig. 2 and 3, fig. 2 shows a schematic diagram of periodic wake-up according to an embodiment of the present application, fig. 3 shows a schematic diagram of periodic detection of a preamble during a wake-up period according to an embodiment of the present application, a wake-up period at a receiving end in fig. 2 is T1, a wake-up duration T2 is included in the wake-up period T1, a plurality of preamble detection periods T3 are included in the wake-up duration T2 in fig. 3, and a time T4 required for detecting the preamble is included in each of the preamble detection periods T3.
In step S2, the transmitting end configures in advance a duration T5 of the transmitted information frame, where the duration is greater than a wake-up period T1 of the receiving end, for example, the wake-up period T1 of the receiving end is 5S, and then the value of T5 is slightly greater than 5S.
Step S3, the receiving end wakes up once every wake-up period T1, and detects the preamble in the wake-up duration time T2 in the preamble detection period T3. The preamble detection period T3 is smaller than the time T4 required for detecting the preamble.
Step S4, if the preamble is detected during the wake-up period, the frame data is continuously received until the frame data is received. And immediately entering into dormancy after the data frame is received, wherein the dormancy time is a code returning time parameter in the frame data, waiting for the end of the dormancy time, namely, returning the service data to the sending end when the code returning time point is reached.
And S5, if the preamble is not detected in the wake-up period, immediately entering a sleep state after the wake-up time is ended, and waiting for the next wake-up and detection.
And S6, repeating the steps S3-S5.
Therefore, the communication method based on the ad hoc network wireless device disclosed by the application is characterized in that the transmitting end continuously transmits the data frame, the receiving end circularly detects whether the preamble exists according to the wake-up period, the preamble judges whether the data needs to be received currently or not, and if the preamble is not detected, the communication method enters a low-power-consumption sleep state. If the preamble is detected, the data frame is received, the low-power-consumption dormant state is entered after the data frame is received, and the code returning is carried out after the code returning time is waited. The method for detecting the preamble greatly reduces the power consumption of the equipment in normal time, and greatly reduces the power consumption consumed during communication by increasing the code return time parameter in the data frame, so that the service life of the equipment is greatly prolonged, and the characteristics of reliability under the ultra-low power consumption scene are met.
