Description of the invention: [Technical field to which the invention pertains] This creation relates to a channel conversion method for a wireless electronic medical device, which is applied to the transmission and reception of human physiological signals and the transformation of their channels. [Prior Art] Taking a stethoscope in a medical device as an example, before the advent of an electronic stethoscope, a conventional stethoscope transmits biological sound to a physician's ear through a hollow long tube, and its disadvantages include _ distortion and long distance caused by miscellaneous The transmission of sound causes loss of sound intensity, etc. After the advent of the axis electronic stethoscope, due to the technological innovation in signal expansion, the disadvantages of weak signal and transmission loss are greatly improved. Although it has been seen that there is a wireless electronic silk green, it uses a contact microphone to collect the analog sound emitted by human organs, and then converts the audio into a digital signal, and transmits the π number through the transmitting circuit. The wireless receiver receives the stethoscope that is used to listen to the human organ information and combines the wireless signal transmission technology to convert various analog audio signals issued by the human organs into digital audio signals and then transmit them, and the wireless receiving device receives the signals. The sound is played back by an electronic earphone or an auscultation tube. Please refer to the figure in Figure 5. 'The above-mentioned wireless electronic stethoscope only provides digital data and reveals the function of using general wireless transmission. However, there is no countermeasure for the channel interference problem encountered in wireless transmission, especially for medical treatment. In behavior, for example, in a medical treatment room, when multiple medical personnel simultaneously measure a patient using an electronic medical device with a wireless transmission (such as a wireless electronic stethoscope), 4 generates a channel stem (4), which may cause the medical personnel to accept other The patient's heart sound, lung sputum * β and other physiological signals cause misjudgment of the symptoms. Although the 1251483 wireless network has its own temperament and casualties, the wireless network can't rely on it, and the wireless, peripheral transmission medium is some form of electromagnetic radiation, such as infrared 'radio waves. In terms of the current wireless transmission technology, the long-distance _ no-domain network transmission standard, an ISM (Industrial Scientific Medical bands) channel that is open, that is, 902~928MHz, 2·4 2·483GHz, 5·725~5· Three channels such as 875GHz. As the communication industry using the ISM channel is gradually increasing, in order to enable interoperability between various products, there is a standard for wireless LAN. _ According to the 电器8〇2·u wireless network standard established by the American Electrical and Electronic Technology Association (dirty), it is possible to let the wireless wireless network device side transmit the radio to the 2 4 GHz broadband to exchange information. The purpose of the paper-based broadband is to use the frequency-bandwidth broadband, also known as free-bandwidth broadband, which is a frequency broadband that users can use without applying to any unit. Its wireless transmission rate has been increased from 2Mbits per second to llMbits today, and will reach a higher speed in the future, supporting more abundant network multimedia transmission. However, according to the IEEE802·11 specification, the operating bandwidth of 802·11a is between 5·18~5·8〇5GHz Φ, while 8〇2.llb and 8〇2.llg are operated in 2 shoulders~Μ3· Radio wave band (so-called Industrial, Scientific and Medical, ISM band). At present, Taiwan can only provide 11 channels for wireless base stations. For example, 8〇2·lib can only provide three channels that do not interfere with each other (ie, channels 1, 6, and 11). That is to say, when the fourth wireless base station joins, no matter which channel is selected, it will be interfered by other wireless base stations. The short-range Bluetooth Tooth (Blue Tooth) is a short-range wireless LAN transmission standard. The origin of Bluetooth is from the mobile phone. In order to solve the convenience of connecting the mobile phone and its surrounding 1251483 line, Wireless transmission technology standards defined and initiated by Los Angeles, Nokia, ΙβΜ, Toshiba and Intel. Bluetooth technology and infrared wireless technology (4) She is a short-distance wireless transmission. Infrared wireless transmission device needs to align the two transmission devices with each other when transmitting data (疋/, 中红外谷易文 to the wall, or other objects) Blocking, so most of the current wireless network products use radio waves as a medium. Among them, the Bluetooth technology is a "point" transmission technology. When transmitting, the data is transmitted from the transmitting rib to the four sides. Bluetooth technology provides radial transmission. On a general network, multiple receivers can share a single transmitter. In the case of medical detection, there is no way to misjudge the misjudgment. Wireless transmission, _ mutual interference phenomenon has no way to respond.
