The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
Embodiment one:
referring to fig. 1, a preferred embodiment of the present invention provides a method for selecting a representative device, including:
s1: the terminal equipment randomly generates a priority value, stores the generated priority value, marks the priority value as the priority value of the terminal equipment, and broadcasts and sends a notification message to the network, wherein the notification message comprises the priority value and the identification information of the terminal equipment for sending the notification message.
The identification information may include information capable of accurately identifying the identity of the terminal device, such as a physical address and/or a network address of the terminal device, so that the relevant message may be sent to the terminal device. In order to store data such as priority values and identification information of the terminal device itself and other terminal devices, the terminal device should be provided with a data storage unit and have functions of writing, deleting, etc. to realize storage and updating of data.
The priority values are defined by a computer program before the respective terminal devices start to operate. The number of priority values and the specific values can be set according to the actual industrial production requirement, for example, 100000 terminal devices are in an industrial internet of things area, the number of non-repeated priority values is at least 100000, and the maximum value of the priority values is at least 100000. Preferably, the priority value may be between 1 and 2 32 Any value among the priority values is 4294967296, so that the actual requirements of industrial production can be met.
For example, a total of 100000 terminal devices in the network have priority values between 1 and 100000, the terminal device a randomly generates a priority value of 1000, the terminal device a sends a notification message to other 99999 devices in the network, the notification message includes identification information such as a physical address and/or a network address of the terminal device a, other devices can recognize and find the terminal device a through the identification information, the notification message further includes the priority value of the terminal device a, and the other devices can store the information that the priority value of the terminal device a is 1000.
S2: the terminal equipment receives the notification messages sent by all the terminal equipment except the terminal equipment, generates a priority table according to the received notification messages, the priority values and the identification information of the terminal equipment, wherein the priority table comprises the priority values and the identification information of the terminal equipment, which are in one-to-one correspondence, and the priority values are arranged in the order from big to small.
For example, the terminal device a separates the identification information and the priority value of each terminal device and the priority value of the terminal device a from each other in the received notification message, gathers the identification information and the priority value, and arranges the priority values in order from large to small to form a priority table, in the priority table, the terminal device a has a corresponding relationship with the priority value of 1000, and other terminal devices have a corresponding relationship with the priority values of the terminal device a.
S3: the terminal device checks the priority table, and determines whether the priority values of more than two terminal devices in the priority table are equal, if so, the terminal device executes S301, and if not, the terminal device executes S302.
S301: judging whether the priority value of the condition of equality is the priority value of the priority value per se, if so, re-executing S1 and S2, otherwise, re-executing S2;
s302: and determining the layer where the representative device is located, the representative device of the layer where the representative device is located and the representative device of the next layer of the layer where the representative device is located according to the representative device judging strategy.
For example, the terminal device a checks that there are no more than two equal priority values in the priority table, which indicates that the priority values are not repeated, and then the terminal device a layers each terminal device in the priority table according to the representative device determination policy, determines each layer of representative devices, and determines itself in the second layer, thereby determining the representative device of the layer where itself is located and the representative device of the next layer of the layer where itself is located.
For another example, the terminal device a checks that there are more than two equal priority values in the priority table, which indicates that there are duplicate priority values, and cannot perform the steps of layering and determining that each layer represents a device, then the terminal device a further checks whether there are priority values of other devices equal to its own priority value in the priority table, determines whether its own priority value is a duplicate value, if its own priority value is determined to be a duplicate value, the terminal device a re-starts executing the steps of the method from S1, completes S1 and S2, and again determines whether there are duplicate priority values in S3 until there are no duplicate priority values, and executes S302 to determine its own layer, the representing device of its own layer, and the representing device of the next layer of its own layer.
For another example, the priority table has a repeated priority value, but the priority value of the terminal device a is checked and judged to determine that the priority value of the terminal device a is not the repeated value, and only the terminal device waiting for the repetition of the priority value is required to regenerate the priority value and update the priority table, so that S2 and S3 are required to be executed again until the repeated priority value does not exist, S302 is executed, and the layer of the terminal device a, the representative device of the layer of the terminal device a and the representative device of the next layer of the terminal device a are determined.
In the present embodiment, the representative device determination policy includes: dividing all priority values into n 1 st layer priority value segments, wherein the device with the largest priority value in each 1 st layer priority value segment is used as 1 st layer device, dividing the device with the largest priority value in each 1 st layer priority value segment into n 2 nd layer priority value segments after eliminating the priority value of the 1 st layer device, using the device with the largest priority value in each 2 nd layer priority value segment as 2 nd layer device, using each 1 st layer device as a representative device of the 2 nd layer devices in the 1 st layer priority value segment, and so on until the m-1 st layer representative device is determined, defining the m and n layers of m-1 st layer devices as the upper layer of the m-1 st layer device, and using each m-1 st layer device as the representative device of the m-1 st layer device in the m-1 st layer priority value segment.
For example, 100000 terminal devices in a network are divided into one hundred layer 1 priority value segments, into 3 layers, the first layer 1 priority value segment is 1 to 1000, the second layer 1 priority value segment is 1001 to 2000, and … … the first hundred layer 1 priority value segments is 99001 to 100000. The priority value of the terminal equipment A is 1000, the terminal equipment A is positioned in the first 1 st layer priority value section of 1 to 1000 and is the equipment with the largest priority value in the 1 st layer priority value section, and the terminal equipment A is the 1 st layer equipment. Terminal devices with priority values of 1 to 999 are divided into one hundred layer 2 priority value segments, the first layer 2 priority value segment is 1 to 10, the second layer 2 priority value segment is 11 to 20, … … the first hundred layer 2 priority value segments are 991 to 999, then the second layer devices comprise one hundred terminal devices with priority values of 10, 20, 30 … … 970, 980, 990, 999, which are all represented by terminal device a. Then the other terminal devices that are not layer 1 nor layer 2 are all layer 3 devices.
The push representative device may employ a policy to push the representative device from bottom to top in addition to the order of push from top to bottom. In the present embodiment, the representative device determination policy includes: dividing all priority values into x y-layer priority value segments, wherein the device with the largest priority value in each y-layer priority value segment is used as the representative device of the y-layer priority value segment in the y-layer, dividing the priority values of all the representative devices of the y-layer into x y-1-layer priority value segments, using the device with the largest priority value in each y-1-layer priority value segment as the representative device of the y-1-layer priority value segment in the y-1-layer, and so on until the 1-layer representative device is determined, defining the y-1-layer device as the last layer of the y-layer device through manual setting, and each y-1-layer device is the representative device of the y-layer device in the y-1-layer priority value segment.
By the method, the terminal equipment in the industrial Internet of things can be used for selecting the representative equipment, and sending the heartbeat packets to the platform server through the representative equipment, so that the number of the heartbeat packets received and processed by the platform server is reduced, and the burden of the platform server and the channel is lightened.
