The room call system consists of several call sources (generally one for each hospital bed), modulation and demodulation carrier module, coupling circuit and monitoring system software. When the call source has a call data signal, the corresponding audio and optical call data signal indication is displayed on the video monitoring system, and the call number can be displayed. If the parallel processing bus expansion mode is adopted, the wiring between hundreds of call sources and servers is too complex, so the system software uses the serial communication function designed by the single-chip microcomputer to make the data signals from the server to each slave computer pass through the power line carrier modulation and demodulation module, and pass through the civil power line to realize the dual data transmission between the server and the slave computer.

Negative ions are called "air vitamins". They can improve air quality, purify air, and have a very important impact on the human body. Breathing an appropriate amount of negative ions every day can strengthen the function of cerebral cortex and mental activity, as well as reduce blood pressure, enhance the function of the heart and increase the function of the lungs. Therefore, negative ions are widely used in household appliances as air purifiers.

Medical center paging system: the medical pager is composed of a calling host installed in the ward nurse station, a calling extension set at the bedside of the ward, a calling extension set in the ward toilet, and a corridor display screen. Once someone presses the call button at the bedside of the ward or in the toilet, the host of the nurse station will send out an audible and visual alarm signal, and the corridor display screen will synchronously display the calling bed number, Nurses can immediately rush to the ward to deal with emergencies. It is important that the call extension in the toilet has waterproof function. In addition, in order to facilitate the work of the staff in the ward, the therapist can install a call and display device so that the therapist can know the situation in time.

The working principle of the medical pager is the called user receiver in the wireless paging system. It consists of superheterodyne receiver, decoder, control and display. It selects the useful signal to be received from the paging signal and interference transmitted by the base station, restores it to the baseband signal of the original paging machine, and generates audio (or vibration) and digital (or letter, Chinese character) messages. The BP machine has two modes of manual tandem and automatic tandem, and the corresponding paging stations are called manual paging stations and automatic paging stations. The manual paging station needs manual operation to encode these information and send signals through the transmitter. According to the line number of the incoming phone, the automatic paging station automatically finds out the caller's phone number and sends it out at the same time, so that the callee can know which phone is calling. Pagers often used are divided into two categories: digital pagers and Chinese pagers. Digital pager is small, cheap and practical. The Chinese pager displays Chinese characters directly, and the information is easy to recognize.

1. Filter adsorption type: use porous filter materials, such as non-woven fabric, filter paper, fiber, foam cotton, etc., to absorb suspended particles and harmful gases in the air, so as to purify the air. 2. Electrostatic dust collection type: the pollutants in the air are charged by static electricity, and then the dust collection device is used to capture and absorb the air dust with charged particles, so as to purify the air. 3. Compound type: simultaneously use filtration and electrostatic precipitation to purify air. 4. Ozone sterilization type: use the strong oxidation of ozone to sterilize the air, remove odor, formaldehyde, bacteria, mold and other harmful ingredients in the air, so that the air can be disinfected and purified. 5. Ozone sterilization filtration type: filter the suspended particles in the air through the filter screen, use the strong oxidation of ozone to sterilize the air, remove odor, formaldehyde, bacteria, mold and other harmful ingredients in the air, so that the air can be disinfected and purified.

Semi digital medical and nursing intercom system - According to the transmission mode of combining LAN and system bus, semi digital originally combines analog signal and network signal. The front extension machine equipment transmission selects traditional analog signal, and the back-end host machine equipment room selects the current network signal. Medical and nursing information intercom system -- information display, voice call, intercom system, broadcast, visual five in one system, according to the LAN transmission technology, is specially used for the voice call and intercom system between hospital nurses and hospital beds; It can also be used in sanatoriums, nursing homes, nursing homes and other places that need nursing intercom systems.
