In view of the contradiction between the demand of high-speed digital-to-analog converter chip and the actual chip manufacturing process and its cost, this paper introduces the principle of random equivalent sampling and realizes the realtime sampling rate 50M Equivalent sampling rate of 1.6G modules. The module includes sampling trigger module, sampling clock generation module, short time measurement...
This paper introduces an intelligent integrated nondestructive testing system based on active the infrared thermal wave detection. The excitation heat source of the thermal wave includes ultrasonic excitation and electromagnetic excitation and exploiting the powerful resources of computer system and LabVIEW software to develop the virtual instrument. The integrated nondestructive testing system based...
Aiming at the problem of large amount of data and large number of nodes in wireless sensor network, this paper proposes an improved directional routing algorithm based on clustering structure. The algorithm combines the efficient energy consumption of the cluster routing algorithm with the optimal performance of the directed diffusion routing algorithm in the process of large data transmission. And...
At present, the research of temperature control algorithm is based on the traditional PID and the improved PID algorithm based on the traditional PID. But in the industry, there are some deficiencies. In order to solve the problem of high overshoot and slow calculation speed in the design of temperature control system. This paper presents a design of temperature control system of adaptive control...
