Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.

As shown in fig. 2, the data issuing system may include: the gateway and the terminal can be connected through an Ethernet, and sub-1G wireless (low-power wireless communication) connection can be used between the gateway and the terminal. The terminal may be an electronic device powered by a battery.
The gateway and the terminal are in the same communication field, that is, the communication between the gateway and the terminal can interfere with each other. The server will group the gateways before the topology is established. The gateways which will generate communication interference are divided into the same group, and only one gateway in the same group is transmitting big data at the same time.
All terminals send heartbeats every hour and randomly join any gateway.
Each data issuing task corresponds to 100 terminals, and each terminal corresponds to one task. The server receives a create task request sent by the terminal and generates a task group, as shown in table 1 below.
Table 1:
task id
Execution time period
Corresponding terminal id list
The execution time period in the task is coarse time, and represents the life cycle of the task. The corresponding terminal id list includes a terminal id corresponding to the task. When the terminal connects to the gateway, it searches the id list to see if there is a need to perform this task.
Because the terminal can be randomly added into any gateway, the created task group needs to be issued to all members in the gateway group, and the terminal request is ensured not to be missed.
Next, the scheme provided by the embodiments of the present application is described as follows.
The target gateway is a gateway that needs to execute a target task in the system, and as shown in fig. 2, when the gateway that needs to execute the target task is gateway a, gateway a is taken as the target gateway.
All terminals refer to terminals that need to execute a target task under a target gateway, for example, as shown in fig. 2, when a gateway a is a target gateway, the terminals that need to execute the target task under the gateway a are: and the terminal 1 and the terminal 2, then, all the terminals which need to execute the target task are the terminal 1 and the terminal 2, and the target gateway allocates the target time slice to the terminal 1 and the terminal 2 in advance.
The target time slice refers to a time slice corresponding to the target gateway, and the target time slice is used for waking up all terminals needing to execute the target task under the target gateway.
The generation process of the target time slice can be described in detail with reference to the following specific implementation manner.
In a specific implementation of the present application, before the step 101, the method may further include:
step A1: receiving the number of gateways of all gateways which need to execute the target task in a gateway group issued by a server and the gateway ID of each gateway; the target gateway is one gateway in all the gateways.
In this embodiment of the present application, all gateways refer to all gateways that need to execute a target task under a server, as shown in fig. 2, all gateways under the server include a gateway a, a gateway B, and a gateway C, and the gateways that need to execute the target task are the gateway a and the gateway C, so all gateways under the server are the gateway a and the gateway C.
The number of gateways refers to the number of all gateways which need to execute the target task under the server.
The gateway ID refers to an ID identifier assigned by the server to each gateway in the gateway group, and as shown in fig. 2, the gateway group under the server includes a gateway a, a gateway B, and a gateway C, where the gateway ID corresponding to the gateway a is 1, the gateway ID corresponding to the gateway B is 2, and the gateway ID corresponding to the gateway C is 3.
It should be understood that the above examples are only examples for better understanding of the technical solutions of the embodiments of the present application, and are not intended to limit the embodiments of the present application.
And after the server side creates the gateway group, the gateway group information is sent to each gateway in the group, and the gateway group information comprises the number of the gateways in the gateway group and the gateway ID.
And B, after receiving the gateway number of all gateways which need to execute the target task in the gateway group sent by the server and the gateway ID of each gateway, executing the step A2.
Step A2: and generating the target time slice according to the number of the gateways.
After the target gateway receives the gateway information of all gateways sent by the server, a target time slice may be generated according to the number of gateways in the gateway information, specifically, the gateway group may generate a time slice corresponding to each gateway according to the number of gateways, for example, if all the gateways in the gateway group include 3 gateways, three time slices may be generated: time slice 1, time slice 2 and time slice 3, the time slice corresponding to gateway a is time slice 1, the time slice corresponding to gateway B is time slice 2, and the time slice corresponding to gateway C is time slice 3.
For example, referring to fig. 4, a schematic diagram of a time slice allocation manner provided in an embodiment of the present application is shown, and as shown in fig. 4, after a gateway group is created by a server, gateway group information is sent to each gateway in the group, where the gateway group information includes the number of gateways in the gateway group and a gateway ID. And each gateway lists the priority in a fixed mode according to the gateway ID, generates a time slice sequence for numbering, and can be distributed to all gateways executing target tasks in a random distribution mode after a plurality of time slices are generated in the gateway group.
It should be understood that the above examples are only examples for better understanding of the technical solutions of the embodiments of the present application, and are not to be taken as the only limitation of the embodiments of the present application.
And after the target time slice of the target gateway is generated according to the number of the gateways, executing the step A3.
Step A3: and determining a target awakening priority corresponding to the target time slice according to each gateway ID and the target gateway ID of the target gateway.
After the target time slices of the target gateways are generated according to the number of the gateways, the target wake-up priority corresponding to the target time slices can be determined according to the gateway IDs and the target gateway IDs of the target gateways, for example, the gateway IDs of all the gateways are: 1. 2, 3, 4 and 5, the target gateway ID of the target gateway is 3, then the target wake-up priority of the target time slice is higher than the wake-up priority of the time slice corresponding to gateway 4 and gateway 5 and lower than the wake-up priority of the time slice corresponding to gateway 1 and gateway 2.
It should be understood that the above examples are only examples for better understanding of the technical solutions of the embodiments of the present application, and are not to be taken as the only limitation of the embodiments of the present application.
And executing the step A4 after determining the target awakening priority corresponding to the target time slice according to the gateway IDs and the target gateway ID of the target gateway.
Step A4: and distributing the target time slice to all terminals needing to execute the target task under the target gateway.
And after the target time slice corresponding to the target gateway is generated, distributing the target time brand milk powder to all terminals needing to execute the target task under the target gateway by the target gateway. As shown in fig. 4, the slot allocation in the gateway uses preemptive allocation. Assuming that the terminal 1 is connected to the gateway, the task id corresponding to the terminal 1 is task number 1. And the gateway allocates the No. 1 time slice to the terminal, and marks the No. 1 time slice task as the No. 1 task. And the terminal 2 is connected to the gateway, the corresponding task id is No. 2, the gateway searches the time slice to find that the time slice No. 1 is occupied by the task 1, and then the time slice No. 2 is distributed to the terminal 2. The subsequent terminal connections are all made in this way.
The manner of acquiring all terminals according to the target wake-up priority of the target time slice may be described in detail with reference to the following specific implementation.
In another specific implementation manner of the present application, the step 101 may include:
substep B1: and determining whether the awakening time of the target time slice is reached or not according to the target awakening priority.
In the embodiment of the present application, the wake-up time refers to a wake-up time corresponding to a target time slice.
After the target wake-up priority corresponding to the target time slice is obtained, whether the wake-up time of the target time slice is reached may be determined according to the target wake-up priority, and specifically, detailed description is given in conjunction with the following specific implementation manner.
In another specific implementation manner of the present application, the sub-step B1 may include:
substep C1: and when the target awakening priority is the highest awakening priority, determining that the awakening time is reached.
In this embodiment of the present application, when the target wake-up priority is the highest wake-up priority, it may be determined that the wake-up time has been reached when the target task is executed.
And a substep C2: and when the target tasks of the gateways corresponding to the awakening priorities higher than the target awakening priority exist and are completely executed, determining that the awakening time is reached.
And when the target tasks of the gateways corresponding to the awakening priorities higher than the target awakening priority exist and are completely executed, determining that the awakening time is up.
Substep B2: and acquiring all the terminals when the awakening time is reached.
And when the awakening time is up, awakening all terminals executing the target task under the gateway by the target gateway.
Multicast is an unreliable transmission mode, and a packet-lost terminal needs to be reissued after the first transmission of big data in an allocated time slice. According to the method and the device, capacity constraint can be added on a time slice allocation mechanism, namely, after a set number of terminals obtains the time slice, the terminals with the same task are added to the terminals without allocating the time slice. In particular, the detailed description may be combined with the following specific implementations.
In another specific implementation manner of the present application, the step A4 may include:
substep D1: under the condition that the number of the terminals of all the terminals reaches the set number of the terminals, distributing the target time slices to the terminals with the set number of the terminals in all the terminals;
substep D2: generating a next time slice;
substep D3: and allocating the next time slice to other terminals except the terminal with the set number of terminals in all the terminals.
In the embodiment of the present application, the set number of terminals refers to the number of terminals that need to be allocated to a target time slice, which is preset by a service person, and the set number of terminals may be 10, 11, 15, and the like, and specifically, may be determined according to a service requirement, which is not limited in this embodiment of the present application.
The next slot is a slot that needs to be allocated to all terminals except for the terminal with the set number.
In the present application, as shown in fig. 4, after 10 terminals of task 1 acquire time slice No. 1, a terminal of the next task 1 allocates a new time slice 3. The method can convert the terminal with indefinite quantity into the terminal with fixed quantity, and has the advantages that the time slice length can be prepared and determined; and secondly, the packet loss state of each terminal can be inquired by using modes such as polling and the like in the packet supplementing stage, and the packet supplementing time is agreed in a unified manner.
In the present application, it is also possible to avoid an extreme situation, such as that all terminals performing the target task access to one gateway, and in particular, the detailed description may be made in conjunction with the following specific implementation.
In another specific implementation of the present application, the method may further include:
step E1: when all terminals executing the target task in the gateway group are positioned under the target gateway, receiving a plurality of time slices with the same time generated by the server according to the gateway IDs and the total time of all the gateways; the total time refers to the preset time required for executing the target task;
step E2: and randomly distributing the time slices with the same time to all the terminals.
In the embodiment of the present application, as shown in fig. 3, the time slices of the gateways in the gateway group are sorted according to the fixed priority group. In an extreme case, all terminals are connected to the gateway C of the low priority group, and the time slices owned by the gateways a and B will not be utilized, and the utilization rate is only 1/3. If 10 terminals are accommodated in each time slice, and 500 terminals require 50 time slices, the maximum allocated time slice sequence number in the gateway C is 150, that is, the time for completing the execution of all tasks.
When all terminals executing the target task in the gateway group are located under the target gateway, the server may generate a plurality of time slices with the same time according to the gateway IDs of all gateways and the preset total time required for executing the target task, allocate the plurality of time slices with the same time to the target gateway, and then randomly allocate the plurality of time slices with the same time to all terminals by the target gateway.
The optimization scheme introduces a random sequence generation method, as shown in fig. 5. And randomly sequencing 150 time slices in the worst case, extracting sequence numbers from the disordered sequence according to gateway codes, and then arranging the sequence numbers from small to large to obtain a new sequence combination shown in the right diagram of the figure 3. Thereby avoiding with a certain probability that gateway C is assigned to time slice number 150 in the extreme case.
Further optimizing, the gateway reports the service condition of the time slice to the server at regular time, and the server rearranges and distributes unused time slices according to the method, adjusts the sequence number of the time slices in real time, and achieves higher utilization rate.
After all terminals assigned with the target time slice under the target gateway are acquired, step 102 is executed.
Step 102: and adjusting the states of all the terminals from a dormant state to an awakening state.
For each task, the data to be sent is the same, and in order to improve the task execution efficiency, a multicast mode needs to be adopted to uniformly update all terminals under the task. At this time, the unified wake-up time of the terminal needs to be appointed to ensure that the task data are received at the same time. When the terminal is connected to the gateway and has a task to be executed, the gateway informs the connected terminal of the appointed unified wake-up time.
After all the terminals allocated with the target time slices under the target gateway are obtained, the states of all the terminals can be adjusted from the dormant state to the awakening state.
After the states of all the terminals are adjusted from the sleep state to the awake state, step 103 is executed.
Step 103: and issuing corresponding data to all the terminals according to the target tasks corresponding to the target time slices.
After waking up all terminals, the target gateway can issue corresponding data to all terminals according to target tasks corresponding to target time slices.
According to the data issuing method provided by the embodiment of the application, when the awakening time corresponding to the target time slice of the target gateway is reached, all terminals distributed with the target time slice under the target gateway are obtained, the states of all the terminals are adjusted from the dormant state to the awakening state, and corresponding data are issued to all the terminals according to the target task corresponding to the target time slice. According to the method and the device, the time slice distribution mode is used, the terminals can finish multicast awakening time distribution in one-time interaction mode under the condition that the participation of the server side is not needed, and the fact that a large amount of data of multiple terminals are issued under the condition that the terminals are in long-term dormancy is guaranteed.
