This paper analyzes some traditional design ideas about serial receiving program. For their shortcomings, a method of subsection receiving with frame synchronization(SRFS) based on DMA is proposed. The main idea of this method is to encapsulate the communication data into a frame with the specified structure, then divide a data frame receiving into several specified segments and make receiving process of every segment to match a certain execution state of receiving algorithm. Meanwhile, this method utilizes the software queue to separate data receiving from data processing. Finally, this paper conducts a compared experiment on a hardware platform of STM32F103RBT6, and the result indicates that the proposed method has prominent performance on suitability, real-time, reliability and so on. Besides, it solves the problem faced by receiving variable-length data with DMA. In a word, the method in this paper can be applied to embedded system with serial communication which demands large amounts of data transmission volume, high-speed communication, strong real-time and reliability.

Currently, the functional requirement of optical small satellites is increasing. The operation mode of track stereo imaging is an important one of optical small satellites, which is in the same orbital period, the optical load image the same target area from the front and behind directions to generate stereoscopic image. This requires the small satellites made rapid large angle maneuver with increasing frequency, and have the high precision steady state after the maneuver. Therefore, the requirements of satellite attitude control system are not only a high bandwidth, but also have higher control accuracy. Control moment gyroscope (CMG) is a large torque actuator than the flywheel torque actuator, and it can provide a higher precision control. Application of symmetrical CMGs and flywheel group to control of small satellite attitude, it can achieve fast and high precision attitude motion, and complete the process of track stereo imaging. The joint control of this method needs the switching stability of two kinds of actuators, which means it has to plan and design the actuator torques, such that the effect of switching between CMGs and flywheel is minimal. In this paper, the switching algorithm is designed, which needs to plan the gimbal angular of CMGs, to solve the problem of switching unstable between two kinds of actuators. The Simulation results show that the maneuvering speed is fast, the good stability and smooth switch process of are achieved.

Nowadays, as the various applications emerge, to address the problem of the end-to-end QoS guarantee in the heterogeneous networks is becoming more and more important. Considering the communication between two nodes within a domain or cross-domain in the heterogeneous networks, we design the scheme of Signaling of Cross-domain QoS Cooperation in heterogeneous networks (SCQC). In SCQC, the SSE nodes can quickly establish the QoS path. To provide the end-to-end communication cross domain, a QoS parameter mapping rule in heterogeneous is designed. Then, we proposed the End-to-end SLA Negotiation algorithm based on the state of the Data Stream (ESNDS), which can effectively guarantee service end-to-end QoS by dynamically adjusting the level of service in different domains according to the current state of the data stream. Through the performance analysis and simulations, we evaluate the time to establish QoS path and end-to-end latency of service with our algorithm. The results prove the effectiveness and feasibility of the ESNDS in guaranteeing the end-to-end QoS in heterogeneous networks.

In the agricultural production, recently there are some problems in the determination of the amount of soil nitrate nitrogen using ion selective electrode such as low accuracy and long detection time. The research on measurement model of soil nitrate nitrogen based on ion selective electrode is carried out in this article aiming to obtain the information of soil nitrate nitrogen quickly and accurately. Simple linear regression equation is adopted to establish the calibration equation of ion selective electrode and the calculated values of this model compared with laboratory measurements show that the model is quite accurate. Then "stepwise fitting method" is used to establish the three-dimensional mathematical model which also has wide application values among the concentration of test solution, the measuring potential of ion selective electrode and the temperature of test solution.
