Figure BDA0003533089920000041
wherein dcrf (t) and dcrf (t +1) represent the duration of the tth and t +1 th data acquisition cycles, respectively; Γ represents a preset processing coefficient, δ (t) represents a data forwarding coefficient in the tth data acquisition period, hstr represents a data forwarding coefficient threshold, and pft represents a preset time length parameter;

Figure BDA0003533089920000051

In the embodiment, the wireless sensor nodes are divided into the satellite nodes and the planet nodes, so that the energy consumption of the wireless sensor nodes can be reduced, and the coverage range of the data acquisition module can be expanded. And the wireless sensor nodes are divided into satellite nodes and planetary nodes by adopting a variable data period, so that the energy consumption of the wireless sensor nodes is balanced in time. In the prior art, wireless sensor nodes are generally divided by a fixed period, or divided once directly. If the division is performed only once, obviously, the planet nodes can quit working in advance due to the fact that the data forwarding amount is too large, energy is consumed rapidly, and therefore the coverage rate of the data acquisition module is low. However, if a fixed period is adopted, the data forwarding situation cannot be considered, so that the energy consumption of the wireless sensor nodes is not balanced. In the invention, the data acquisition period is judged to be expanded or reduced by the data forwarding coefficient. The data forwarding coefficient is mainly calculated by the number of the wireless sensor nodes with the newly increased energy lower than the preset energy threshold in the previous acquisition period and the average data transmission amount of the wireless sensor nodes, and the larger the two variables are, the heavier the data forwarding task is, so that the data forwarding coefficient is larger than the threshold, the time of the next data acquisition period is shortened, the following change of the data acquisition period is realized, the energy consumption among the wireless sensor nodes is effectively balanced, the average working time of the wireless sensor nodes is prolonged, and the logistics support pressure is reduced.
Preferably, the dividing the wireless sensor node into a satellite node and a planetary node includes:
with the data transceiver as the center of a circle, dividing the wireless sensor nodes into Q sets by the following method:
for a wireless sensor node i, if dist (i, bs) belongs to ((Q-1) lambdar, qlambdar ], the wireless sensor node i belongs to a qth set, dist (i, bs) represents the distance between the wireless sensor node i and the circle center, Q belongs to [2, Q ], lambda represents a set control coefficient, lambda belongs to 0.8 and 0.9, and the 1 st set is a set of all wireless sensor nodes of which the distance between the wireless sensor node i and the circle center is less than or equal to lambdar;
obtaining a planetary node by:
for the wireless sensor nodes in the 1 st set, respectively calculating the communication capacity value of each wireless sensor node;
the wireless sensor nodes with the communication capacity values larger than the preset communication capacity value threshold are used as planet nodes and stored into the 1 st planet node set planodU1；
For the wireless sensor nodes in the q set, the planedU can be directly connected with the q-1 planetary node setq-1In the set dtdU to be divided, wireless sensor nodes in which any one planet node performs single-hop communication are stored in the set dtdU to be dividedqPerforming the following steps;
respectively calculate dtdUqTaking the wireless sensor node with the communication capacity value larger than a preset communication capacity value threshold as a planetary node, and storing the planetary node into a qth planetary node set planedUq；
All wireless sensor nodes contained in the Q planetary node sets are used as planetary nodes, and the wireless sensor nodes except the planetary nodes are used as satellite nodes.
According to the invention, when the wireless sensor nodes are divided into the satellite nodes and the planet nodes, a random selection mode is not adopted, and the planet nodes are unevenly distributed due to the random selection mode, so that the time for transmitting the environmental data to the early warning module is influenced, and the abnormal environmental conditions of a construction site cannot be found in time by workers. When the wireless sensor nodes are divided, the wireless sensor nodes are divided into different sets according to the distance between the wireless sensor nodes and the circle center. Then, the division is carried out according to the distance between the wireless sensor nodes in the sets and the circle center from small to large, so that each set comprises the planet nodes, and the respective uniformity of the planet nodes is effectively improved.

In the above embodiment, the communication capability value is calculated from the energy, the average distance to the neighboring node, and the average hop count to the data transceiver device, and the higher the energy, the smaller the average distance to the neighboring node, and the smaller the average hop count to the data transceiver device, the larger the communication capability value is, and the better the communication capability value is suitable for serving as data forwarding.
