Combines with the technologies of network communication,embedded computer,automation,virtual instrument,device diagnostics and maintenance,the embedded e-Maintenance devices is designed for a remote monitoring,diagnostics, maintenance and controlling devices by way of being embedded into the object to be monitored.
To overcome the present limitations of passive biochip,based on the basic principle of antigen-antibody reaction,we develop an antigen-antibody reaction model of solid-phase surface and design a novel active biochip system according to this model,which introduces the negative pressure and controlling devices to control the immunoreactions on the nitrocellulose(NC) membrane.
According to the current situation of the cities who have metro systems, this paper discusses that, to develop urban track traffic, a suitable mode should be carefully selected, that the domestic equipment should play a role of majority, and that to assure safe running of trains, the advanced technology, material and automatic controlling devices should be introduced.
Combining with the technoloies of network communication, embedded computer, automation, virtual instrument, device diagnostocs and maintenance, the embedded intelligent maitenance devices is designed for a remote monitoring, diagnostics, maintenance and controlling devices by the way of being embedded into the object to be monitored.
The process of research and development of the two kinds of marine intelligent engine series, ME and RT-flex, and their electric controlling devices, characteristics parameters as well as applications in real ships are introduced briefly.
We introduced a new digital thermometer DS18B20 in detail and designed a high-accuracy temperature controlling devices based on DS18B20. The experiment results prove that the temperature-controlling devices we designed can effectively decrease the temperature coefficient of spectral radiance standard detector and is reliable.
By utilizing an automatic controlling device for the air conditioning equip.ment in a small spinning laboratory, possible variations in temperature and relative humidity of the air are studied. According to the actual measurement, the maxinum variation of temperature of the air is ±0.5℃., while that of relative humidity,±4％. The construction diagrams and functions of the mechanisms of the device are given and the possibilities of increasing its sensitivity are also discussed.
A water gate on fidal Channel is operated automutically through theuse of microcomputer controlling device. The gate discharges or leadsin 300000m~3 more water in a tidal cycle as compared with manual opera-tion. The main considerations in the development of the derice are pre-sended in this paper.
