The invention concerns the bit error resilience of an IP protocol stack based on a secure link layer, in which packet flows are header compressed according to a suitable header compression standard. According to the invention, by analyzing each packet at the link layer it can be determined whether the packet is a full header packet, in which case the link layer checksum evaluation is used as normal for discarding faulty full header packets, or a header compressed packet in which case the link layer checksum evaluation is ignored and the packet is propagated upwards in the protocol stack. This solution not only opens up for more intelligent higher-level handling of faulty header compressed packets, but also solves the problem of properly protecting full header packets at the link layer. In order to compensate for ignoring the link layer checksum evaluation for header compressed packets, header protection is introduced at the header compression level of the link layer by using one or more local checksums. The invention is particularly applicable to delay-sensitive real-time data such as compressed voice or video.

The invention relates to an intelligent pesticide applying system and a control method of a plant protection unmanned aerial vehicle. The system is provided with a meteorological station used for measuring environment parameters and sending collected data to a ground station. The ground station sends the environment parameters, pesticide applying control parameters and control commands to an onboard pesticide applying controller on the plant protection unmanned aerial vehicle through a wireless data transmission module. Meanwhile, a flight controller measures real-time geographic information parameters and flight parameters of the plant protection unmanned aerial vehicle and sends collected data to the onboard pesticide applying controller in real time. The onboard pesticide applying controller conducts autonomous programmed decisions by combining the flight parameters, the environment parameters, the pesticide applying control parameters and the control commands, a miniature diaphragm pump and two centrifugal atomization disc sprayers are independently controlled, and therefore the pesticide liquid flow, the mist drop diameters and spraying width parameters of the plant protection unmanned aerial vehicle are intelligently controlled. By means of the intelligent pesticide applying system and the control method, it is guaranteed that pesticide in an operation area is quantitative and evenly sprayed in a fully covering mode, the phenomena of repeated spraying and miss-spraying of the pesticide are avoided, the pesticide applying quality is improved, and effective prevention and treatment of farmland pest and disease damage are guaranteed.

A data transfer system allowing high-quality transfer of streaming data through a network having a relatively large delay variation in data delivery is disclosed. When transferring streaming data in packets from a server computer to a client computer through a repeater provided in the network, the repeater buffers a streaming packet for a set time period before forwarding it to the client computer. The set time period is determined so that a receiving time interval of packets at the client computer is substantially equal to a sending time interval of packets at the server computer.

For supporting a relative positioning, information on barometric pressure at a first device and information on barometric pressure at a second device is converted into a difference in altitude between the first device and the second device. The difference in altitude between the first device and the second device is then used in determining a position of the first device relative to the second device.

The invention discloses a method and a device for message transmission. By employing channel occupying parameters and message retransmission parameters as adjustment references, message transmission treatment is conducted by dynamically enabling a channel reservation mechanism to work and stop working; accordingly, when in severe spatial environment and busy time, the channel reservation mechanism of an RTS/CTS mechanism or a CTS-To-Self mechanism is reasonably used to transmit messages; the method decreases use conflicts of system resources and improves WLAN network application quality.

The invention relates to the technical field of block chain, in particular to a block chain node evolution method and a block chain node. The method comprises the following steps: the target block chain node obtains the confirmation result of the service function, and the service function is executed by the target block chain node; the target block chain node evolves the service function accordingto the confirmation result. Because you do not need to predefine privileged nodes, according to the result of the user executing the service function at the corresponding block chain node, evolutionof the service function, so as to gradually and flexibly adjust the node 's service function role, so as to maximize the node behind the participants' business capabilities, while maintaining the original intention of decentralization of the block chain, so that the application quality of the entire block chain system can be improved.
