Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a bidirectional awakening method and a system thereof, which aims to realize bidirectional awakening of a communication node and a communication terminal, wherein a plurality of detection windows are periodically arranged on the communication node or the communication terminal (namely a receiving node), if communication data sent by the communication terminal or the communication node (namely a transmitting node) is not detected, the receiving node is controlled to enter a dormant state, if an awakening signal sent by the transmitting node is detected, the rest communication data of the transmitting node is further received, the receiving or detecting window is not required to be opened all the time to wait for the communication data, and through setting a random transmitting interval of the transmitting node, the interference caused by the simultaneous data transmission of a plurality of transmitting nodes is avoided as much as possible, the communication energy consumption is reduced, the communication efficiency is improved, and the effect of low power consumption of communication is realized.
Referring to fig. 1, fig. 1 is a flowchart of a bidirectional wake-up method provided by the present invention, where the bidirectional wake-up method is implemented by using a first device and one to more second devices, the one to more second devices are respectively connected to the first device in a wireless communication manner, when the first device is a transmitting node, the one to more second devices are all receiving nodes, and when the first device is a receiving node, the one to more second devices are all transmitting nodes.
For example, the first device is a communication node (AP), the second device is a communication terminal (UE), and the first device is used for sensor data acquisition, referring to fig. 2, fig. 2 is an uplink communication timing diagram of the bidirectional wake-up system according to an embodiment of the present invention, fig. 2 shows the uplink communication timing diagram, the receiving node is an AP, and one to more transmitting nodes are: UE (user Equipment)1、UE2……UEn。
Because of the bidirectional wake-up, if the downlink communication is the case, referring to fig. 3, fig. 3 is a downlink communication timing diagram of the bidirectional wake-up system provided in an embodiment of the present invention, where a transmitting node is an AP, and one or more receiving nodes are: UE (user Equipment)1、UE2……UEn. I.e. the first device may act as a transmitting node or a receiving node and the second device may act as a transmitting node or a receiving node.
The bidirectional wake-up method includes steps S1-S3:
s1, the receiving node periodically opens a receiving detection window lasting for a first time length according to a first time interval; the step S1 includes sub-steps S11-S12:
s11, setting a receiving time period through the receiving node; for example, if the receiving time period is one day, the communication data received by the transmitting node on that day is regarded as data corresponding to that day.
S12, the receiving node periodically opens a receiving probing window lasting for a first length of time according to a first time interval in the receiving time period. The first time length is D in FIG. 21。
S2, the transmitting node transmits communication data for multiple times according to multiple random second time intervals, wherein the communication data comprises a wake-up signal for waking up the receiving node and one to multiple data packets; the step S2 includes sub-steps S21-S23:
s21, acquiring the second time interval:
wherein, T1For the first time interval, R is a random positive integer, T2Setting the second time interval as M is a preset positive integer, and setting the maximum value of N as M; preferably, it is ensured that the intervals of opening the detection windows of the receiving nodes are dense, and the wake-up signal transmitted by the transmitting node is more easily received than the transmission intervals of the transmitting node. RxT1＞0，R×T1The signal interval of two adjacent communication data of a transmitting node is an integral multiple of T1, i.e. the difference between the time point when the transmission of the next communication data starts and the time point when the transmission of the previous communication data completes, and should be greater than the second time length, so that the transmitting node can not generate time interleaving when transmitting the adjacent communication data. And the transmitting node sends the communication data at least M times, so that the receiving node is ensured to detect the wake-up signal transmitted by the transmitting node in the receiving detection window. RxT1Providing a fixed phase difference in time, N x T, between a transmitting node and a receiving node1/M moving each transmission of a transmitting node backwards by T1And the phase/M is moved for M times, so that the transmitted wake-up signal can be ensured to cover the detection window of the receiving node once no matter the time difference between the transmitting node and the receiving node during the first transmission.
If the transmitting node transmits for the first time, the transmitting duration at the current moment is T1/M+D3The communication data of (1). The time of the first occurrence can be adjusted according to the requirements of each transmitting node.
Moreover, through the setting of the random positive integer R, the interference caused by the simultaneous data transmission of a plurality of communication terminals is avoided as much as possible.
S22, setting the second time length for transmitting the wake-up signal to be T1(ii) a/M; wherein the first length of time is less than the second length of time. In order to achieve as low power consumption as possible for the receiving node, the first time duration should be set to be very small, so that the time for opening the receiving detection window each time continues to receive data as long as the wake-up signal of the transmitting node is detected, otherwise the window is closed to enter a sleep state, and the receiving detection window is opened again after waiting for a period of time.
S23, the transmitting nodes are all according to T2Interval transmission multiple continuous T1/M+D3The communication data of (1); wherein D is3A third time duration for transmitting a data packet corresponding to the wake-up signal.
Preferably, the wake-up signal is a pseudo-random wake-up signal or a preamble. The present invention provides embodiments of the following wake-up signal:
sending a repeating wake-up packet of length D2＝T1/M+D3. Namely T1And repeatedly sending a data packet representing the wake-up signal in the/M time period. D3And transmitting data packets of other communication data, wherein the data packets can be transmitted for 0 time and several times. The data packet structure is just to regard the data packet as a bit stream, and is suitable for small wireless and LORA technologies.
S3, if the receiving node detects the wake-up signal transmitted by the transmitting node in the receiving detection window, continuing to receive the data packet of the communication data including the wake-up signal; and if the receiving node does not detect the wake-up signal transmitted by the transmitting node in the receiving detection window, entering a dormant state. If the receiving node detects the wake-up signal transmitted by the transmitting node through the receiving detection window in the receiving time period, continuing to receive a data packet of communication data including the wake-up signal; preferably, the wake-up signal has at least two parts, and the two parts have a predetermined correlation therebetween, and since the at least two parts of the wake-up signal sent by the transmitting node have a predetermined correlation therebetween, after the receiving node receives the wake-up signal in the reception detection window of the detection period, the receiving node can determine which transmitting node the received signal comes from as long as it determines that the at least two parts of the wake-up signal have the predetermined correlation therebetween. However, for the noise or interference signal received by the receiving node, the receiving node may determine that the received signal is a noise or interference signal because there is no correlation or a preset correlation between symbols of the noise or interference signal. Thus, noise or interference signals will not cause false wake-up of the receiving node. Meanwhile, due to the adoption of a dynamic coding method, a receiving end can carry out correlation judgment from any received correct code element, so that the detection period width of the receiving end can be very narrow, and the power consumption is reduced; moreover, the wake-up sequence integrates bit synchronization information, wake-up information and time information, so that the coding efficiency is particularly high, and the communication process is simpler and more reliable.
Preferably, the bidirectional wake-up method further includes step S4:
and S4, uploading the received communication data to a preset server through the first equipment. Wherein the received communication data is associated with the reception time period by the first device; for example: the receiving time period is set to be a certain day of a month, the communication data received by the first device on the certain day is related to the month, further, the second device can be a terminal to be read, the data volume of the second device to be read is very small, and the second device is generally read once a day or a month, so that the first device only needs to open a receiving detection window at a specific certain period, and each second device on the day can complete the reading operation on the month only needs to be detected once by the receiving detection window.
And then, uploading the communication data after the contact is established to a preset server through the first equipment. For example: and the meter reading data of each month is uploaded to the server, so that the trouble of manual meter reading is saved, and the receiving detection window is set to be small enough to realize low power consumption of the whole network.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a bidirectional wake-up system 100 provided in the present invention, where the bidirectional wake-up system includes a first device 1 and one to more second devices 2 of the above signal transceiving method, and the one to more second devices 2 are respectively connected to the first device 1 in a wireless communication manner. For example, the first device 1 is a communication node (AP), that is, the AP may be a concentrator, a gateway device, and the like, the second device 2 is a communication terminal (UE), and further, the first device 1 is a communication node for meter reading, and the second device 2 is a communication terminal for meter reading, such as: water meter, gas meter … …
Because the data required to be read by the water meter, the gas meter and the like is only a numerical value, the data amount of the second device 2 to be read is very small, and the data amount is generally read once a day or a month, so the communication link is an uplink communication link under general conditions, the first device 1 only needs to open a receiving detection window at a specific certain period, and each second device 2 only needs to be detected once by the receiving detection window at the same day to complete the reading operation at the same month. Moreover, due to bidirectional wake-up, in the case of downlink communication, the first device 1 may also actively wake up the second device 2, and notify the second device 2 to upload the meter reading data value of the first device 1 in real time.
In order for the power consumption of the first device 1 to be sufficiently small, the receive probing window of the first device 1 may be very small each time it is opened, and the first time length of the receive probing window may be very small.
In addition, first equipment 1 and second equipment 2 all can adopt battery powered, because need not to carry out commercial power construction and network maintenance, first equipment 1 and second equipment 2 plug-and-play.
Preferably, the signal transceiving system further comprises a server 3, and the server 3 is connected to the first device 1 through a network. For example: the first device 1 can buffer and arrange the communication data uploaded by the second device 2, and timely upload the received communication data to the server 3 through the internet every day or every month.
