Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 is a flow chart of a segment pushing method in a low-power consumption network according to an embodiment of the present invention, as shown in fig. 1, where the embodiment of the present invention provides a segment pushing method in a low-power consumption network, including a gateway in a network structure and a terminal node within a preset range of the gateway, and includes:
step S101, when the terminal node is detected to be in an off-network state, acquiring the timing moment of a registration timer, and when the current moment reaches the timing moment, sending an on-network frame to a gateway with the best signal in a preset range by the terminal node.
Specifically, when detecting that the terminal node is in an off-network state after being powered on, i.e. when not connected to a network, the timing moment of a registration timer is obtained, for example, registration timing is once every 10 minutes, after the registration timing is reached, the terminal node can sequentially apply for registration on all channels of the gateway in a preset range, if a gateway response exists, gateway information is stored in a registration list, and then after applying for registration on all channels, the terminal node sends a network access frame from the gateway with the best registration list selection signal to apply for network access.
In addition, when the terminal node does not receive a response frame of the corresponding gateway within a preset duration, or the terminal node receives a rejection frame of the corresponding gateway, it is indicated that there is a barrier in connection with the corresponding gateway, for example, if the distance is too long, the gateway information of the corresponding gateway is deleted, the gateway with the best signal is selected from other gateways within the preset range, and the gateway is sent to the network frame, and when the terminal node does not have the gateway within the preset range, the terminal node enters a sleep state, and when the next time arrives at a timing moment, the terminal node is awakened to detect the gateway within the preset range.
Step S102, after receiving a network access frame, the gateway obtains a request sequence number corresponding to the network access frame, determines a corresponding time-sharing number according to the request sequence number, obtains a current network scale and a corresponding data push frequency, sets a corresponding time-sharing unit duration based on the data push frequency, and feeds back the time-sharing number, the network scale and the time-sharing unit duration to the terminal node.
Specifically, after the gateway receives the network access frame sent by the terminal node, the node address in the network access frame is obtained and stored, where the node address may be obtained through carrying in the network access frame, or may be obtained when the terminal node applies for registration by the gateway, in general, the terminal node that completes registration may directly access the network, and determines a corresponding request sequence number and a corresponding time-sharing number when the terminal node accesses the network, where the time-sharing number may be a corresponding sequence number allocated by the gateway to the terminal node according to the number of the terminal nodes that access the network and the corresponding network access time, and determines a current network size, that is, the number of the terminal nodes that access the network, and a corresponding data push frequency, that is, for the type of the terminal node, a frequency of one minute push, one time push, one month push, and so on, and then sets a corresponding time-sharing unit duration based on the frequency, in general, the more frequent the push frequency, the shorter the time-sharing unit duration, and then the time-sharing number is fed back to the corresponding terminal node.
And step S103, after receiving the feedback information of the gateway, the terminal node calculates the self push time-sharing time of the terminal node based on the time-sharing number, the network scale and the time-sharing unit time length, performs clock synchronization, enters a sleep state, and wakes up the terminal node to send push information to the gateway until the clock enters the push time-sharing time.
Specifically, after the receiving node receives the feedback information of the gateway, based on the time number, the network scale and the time-sharing unit duration, the pushing time-sharing time of the terminal node is calculated, for example, the gateway distributes the time number P to the node to be 5, the network scale M is 50, and the time-sharing unit T space 1000 ms, the self push interval calculated by the terminal node is m×t space The first push time is determined according to the time-sharing number P, namely 50 seconds, namely the terminal node can push data to the gateway at 0 point, 0 minute and 5 seconds, 0 point, 0 minute and 55 seconds, 0 point, 1 minute and 45 seconds and the like, and the gateway can allocate the time-sharing number P to the node as 12 when the node accesses the network, the network scale M is 360, and the time-sharing unit T space If the time is 10000 ms, the node can push data at the time of 0 point 2 minutes, 0 seconds, 0 ms, 1 point 2 minutes, 0 seconds, 0 ms, and the like, and at other time except the data pushing time, the terminal node enters a sleep state, and when the clock enters the pushing time sharing time, the terminal node is awakened to send push information to the gateway.
Step S104, after receiving the push information, the gateway acquires a target node and a corresponding node address corresponding to the push information, determines a push time-sharing time table corresponding to the terminal node based on the time-sharing number, the network scale, the time-sharing unit duration and the corresponding node address, and stores the push time-sharing time table.
Specifically, after the gateway receives the push information, determining a target node and a corresponding node address for sending the push information, and establishing a push time-sharing time table corresponding to the terminal node according to a time-sharing number, a network scale, a time-sharing unit duration and the corresponding node address corresponding to the target node, wherein the push time-sharing time table comprises push times of all the middle single nodes of the gateway access to the network, and the push time-sharing time table is stored, so that a worker can conveniently inquire the corresponding terminal node.
In addition, a terminal node sequence number table corresponding to the terminal node which has been accessed to the network in the gateway can be generated, wherein in the terminal node sequence number table, the terminal nodes are ordered according to the access time of the terminal node in the gateway, a time division number is allocated to the corresponding terminal node based on the request sequence number, then when the terminal node which has been accessed to the network in the gateway is detected to be accessed to the network, the corresponding sequence number of the network-exiting node in the terminal node sequence number table is deleted, the terminal node sequence number table is not modified, and because the modification needs to be modified together with other terminal nodes, the modification is not performed, only the sequence number corresponding to the deleted node is left, and when the new node access is detected, the corresponding spare part is complemented, and the corresponding information of the deleted node is synchronously updated to the pushing time table, and the other node information is not modified.
In addition, when a new node in the gateway is detected to be connected to the network, in order to avoid affecting other nodes, the least unit time of the terminal nodes pushed in the push time-sharing time table is acquired, all the terminal nodes corresponding to the unit time are acquired, all the terminal nodes in the unit time are distributed with the same time-sharing number, network scale and time-sharing unit time length, and are synchronously updated into the push time-sharing time table, namely, the new node and the time-sharing number of the other nodes pushing the least unit time are put together, push information is received together, and therefore the influence on the node information of the other nodes can be avoided.
The embodiment of the invention provides a segmented pushing method in a low-power consumption network, which comprises a gateway in a network structure and a terminal node in a preset range of the gateway, wherein when the terminal node is detected to be in an off-network state, the timing moment of a registration timer is acquired, and when the current moment reaches the timing moment, the terminal node sends an on-network frame to the gateway with the best signal in the preset range; after receiving the network access frame, the gateway acquires a request sequence number corresponding to the network access frame, determines a corresponding time-sharing number according to the request sequence number, acquires the current network scale and the corresponding data push frequency, sets a corresponding time-sharing unit duration based on the data push frequency, and feeds back the time-sharing number, the network scale and the time-sharing unit duration to the terminal node; after receiving the feedback information of the gateway, the terminal node calculates the self push time-sharing time of the terminal node based on the time-sharing number, the network scale and the time-sharing unit time length, performs clock synchronization, enters a sleep state, and wakes the terminal node to send push information to the gateway until the clock enters the push time-sharing time; after receiving the push information, the gateway acquires a target node and a corresponding node address corresponding to the push information, determines a push time-sharing time table corresponding to the terminal node based on the time-sharing number, the network scale, the time-sharing unit duration and the corresponding node address, and stores the push time-sharing time table. Thus, by the sectional pushing, the nodes can push data only at the pushing time. The method and the device avoid the nodes to push data to the gateway at the same time and avoid push conflict, thereby improving the push success rate.
