The invention discloses a method for regulating a sleep cycle of a mobile station on the basis of service reshaping and channel prediction and mainly solves the problem that the mobile station is frequently switched between a monitoring window and a sleeping window in the conventional method. In the method, the regulation is carried out in three states of a monitoring window first frame period, adata sending and receiving period and a sleeping window period, wherein in the monitoring window first frame period, a base station compares time for transmitting data packets in a buffer zone with the length of a last sleep cycle so as to reshape small burst services into large burst services; in the data sending and receiving period, the mobile station carries out channel prediction, so that the base station regulates the sleep cycle of the mobile station according to a real-time condition of a channel; and in the sleeping window period, a transceiver is turned off through the mobile station so as to reduce energy consumption. In the invention, the sleep cycle of the mobile station can be regulated according the real-time condition of the channel and the sizes of the burst services, so that the energy consumption of the mobile station is minimized under the condition of guaranteeing the service quality of service (QoS).

The invention discloses an updating method, device and network equipment of a media access control address table. The updating method comprises the following steps: when learning new address table entries, judging whether the number of the address table entries in an internal address table is more than the set upper waterline; when the number of the address table entries in the internal address table is larger than the set upper waterline, transferring at least one address table entry except the new address table entries from the internal address table to an external storage until the number of the address table entries in the internal address table is less than the set lower waterline; and when the number of the address table entries in the internal address table is not more than the setupper waterline, avoiding the address table entries in the internal address table from being transferred to the external storage. By utilizing the method, the frequent transferring of the address table entries between the internal address table and the external storage is avoided, the memory occupancy rate is reduced, and the system performance of the network equipment is improved.

The disclosure relates to a simulation platform, an experimental system and a method for a reservoir leakage detection experiment, including a sand box, the upper part of the sand box has an opening to expose the inner cavity of the sand box; the upper surface of the bottom wall of the sand box is covered with a soil layer One end of the sand box is provided with a simulated dam body, the simulated dam body is supported by the overburden layer, and the side of the simulated dam body close to the sand box inner cavity is enclosed with the sand box inner wall to form a water storage tank, and the simulated dam body and the sand box The relative position can be adjusted to change the size of the water storage tank; the water storage tank can be filled with experimental water to simulate the water resources stored in the reservoir; the bottom wall of the sand box is provided with a drainage device to drain the seepage from the covering soil layer. Drain the leaked water.

The invention relates to a situation awareness-based adaptive data transmission method applied to an opportunistic crowd sensing network and belongs to the wireless sensor network and mobile ad hoc network technical field. According to the method, nodes in the network estimate the node residual energy of the nodes themselves, the encounter probability of the nodes and a destination node and the hops of message transmission according to the conditions of the nodes themselves and the historical information of the network, judge a network environment where the nodes are located currently by using local topological information of positions where the nodes are located, and selects suitable data transmission mechanisms. With the method adopted, communicated MANET subnets in the network can be accurately identified, and are fully utilized in a data transmission process, and the communicated MANET subnets have little possibility of being affected by the mobility of the nodes and the time variance of network topology, and the success rate of data transmission can be improved, network overhead can be reduced, and the robustness of a data transmission strategy can be improved.

The invention discloses a fluid storage tank. The fluid storage tank includes a tank body and a ventilation piston. The tank body is used for storing paint. One end of the tank body can be connected to a spray gun, the other end is provided with an air inlet, and the ventilation piston is provided with a plug. The plug-in part is inserted into the air inlet, and the plug-in part is provided with a limit protrusion, and the limit protrusion is used to prevent the ventilation piston from coming out of the air inlet. The fluid storage tank can be used not only as a watering can, but also as a paint storage can in cooperation with the spray gun, avoiding the traditional operation of frequently transferring paint back and forth between the special watering can and the special storage can, and improving the spraying efficiency. Efficiency in storing paint.

The object of the present invention is to provide a method, device and system for file transmission. Compared with the prior art, the present invention uses the service device to generate the first signaling, and when the user equipment sends the file transfer request, verifies the file transfer request based on the first signaling, if the first If the signaling already corresponds to the transferred file, reject the file transfer request; otherwise, if the first signaling has not yet corresponded to the transferred file, then allow the user equipment to perform file transfer; thereby using the first signaling to Limit the number of file transfers to ensure that one signaling corresponds to only one file transfer, which effectively avoids possible conflicts when multiple file uploads occur, and also allows users to check the uploaded files, avoiding Multiple views of uploaded files. Therefore, the present invention can ensure the security, reliability and effectiveness of file transmission, and at the same time improve user experience.
