Researches And Developments Of Wireless Bed Monitor

In the real world, the health surveillance for serious disease patients and protected person needs to be nursed by some hard-working people who pay attention to patients’ body changes all the time. However, the accident maybe allegedly due to guardians’ negligence.In the late eighties and early nineties, a small quantity of medical care equipment was imported into our country. Recently, with the great development of the national economy and the rapid improvement of people’s living standard, the medical care equipment in our country has experienced important stages, such as the introduction, imitation, innovation, performance improvements, all-round improvement, innovation, and others. Up to now, it is in a rapid development stage and can meet the patients’care needs.However, at present, most of the medical monitoring instruments in our market have adopted the method of sensor fixed on ward, and been connected to the monitoring host through But this equipment also has a lot of disadvantages. Firstly, it means huge potential security problems because of some wires fixed on patients’bodies. Secondly, the monitoring host and patients must be in the same room, so it limited patients’ freedom. Thirdly, because of some wires fixed on patients’bodies, it can’t apply to infants and young children. The author found that it was still blank that the wireless remote monitor is applied to hospital and berth. So the research and development of berth monitor will play a vital important role for infants and patients.The main purpose of this paper is to design a new-style wireless monitor according to actual demands of infants and patients, that can keep watch on the users’body changes at all times. In order to cater to the demands of modern monitoring market, it consists of multiple techniques. The program makes use of single-chip microcomputer technology and Radio Frequency wireless transmission technology to realize the exploitation of Wireless Bed Monitor, and it could meet the needs of volume and cost reduction, detection of signal, calculations and dynamic monitoring parameters real-time updates, besides,it can apply to a variety of environments.According to the production process, this paper explains the implementation process in detail from various aspects, such as the design of hardware circuit, the selection of core components, the software systems design, the development of the finished product, the actual function test and other aspects. The main contribution of the paper is as follows:1.It presents the the structure, functions, and property of multifunctional wireless berth monitor, and illustrates its hardware structure and principle.2.It presents the developing scheme based on single-chip microcomputer.3.It introduces the software design and implementation scheme.4.1t introduces the design of Circuit board, and the drawing and production of PCB.5.It presents the overall debugging scheme of system, and has finished the actual performance tests. Test results shows that it can withstand the test of all kinds of complicated work environment.With the method based on single-chip microcomputer adopted, this system has solved out the problem of conductor jointing and long distance transmutation, and it is convenient to use at a low cost, equipped with high reliability and quick reaction, and has the important practical significance. Besides, this wireless bed monitoring system has also provided reference value for similar systems.
