Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described below with reference to specific embodiments shown in the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

According to the technical scheme, as shown in fig. 1, the infectious disease room monitoring system based on the power line communication technology mainly comprises an STM32 single chip microcomputer, a temperature and humidity sensor module, an electrocardio acquisition module, a carrier communication module, a serial port communication module and the like.

1. The STM32 singlechip adopts STM32F407IGT6 chip of ST company. The core is Cortex-M432-bit RISC, the working voltage is 1.8V-3.6V, the storage resources are 1024kB Flash and 192+4kB SRAM, the debugging and downloading of a JTAG/SWD interface are supported, and the IAP is supported.

2. The temperature and humidity sensor module adopts DHT11 of Olympic electronics, Inc. The temperature and humidity composite sensor containing calibrated digital signal output is applied to a special digital module acquisition technology and a temperature and humidity sensing technology, and ensures that a product has extremely high reliability and excellent long-term stability.

3. The electrocardio acquisition module adopts MAX30102 of Meixin MAX3010x series. It adopts a 1.8V power and an independent 5.0V power that is used for inside LED, is applied to wearable equipment and carries out heart rate and blood oxygen collection and detect.

4. The carrier communication module selects ST 7540. The chip adopts an FSK modulation mode, half-duplex communication and power line highest communication speed 4800BPS, and is a power line communication chip which is widely used and has the most reference design.

5. The serial port communication module selects CH 340G. The USB interface is a switching chip of a USB bus, and realizes USB-to-serial port or USB-to-printing port.

The general flow of the system is shown in fig. 2, when the utility model works, the data collected by the temperature and humidity sensor DHT11 and the electrocardio collecting module MAX30102 are transmitted to the STM32 single chip microcomputer, the STM32 single chip microcomputer processes the data and transmits the data to the first carrier communication module ST7540 in batches, the first carrier communication module transmits the signal to the power line through modulation, the power line transmits the signal to the second carrier communication module, the second carrier communication module demodulates the signal and transmits the data to the PC terminal, the signal judges whether the measured data exceeds the range of normal data on the PC, if the data exceeds the range, the indicator light on the PC flashes (alarms), and simultaneously transmits a feedback signal to the second carrier communication module, the second carrier communication module modulates and transmits the data to the first carrier communication module after receiving the feedback signal, after the first carrier communication module receives the signal, telling STM32 singlechip, STM32 singlechip will transmit next batch of signal after receiving the signal, repeat so to reach the purpose to the real time monitoring of infectious disease room, if the data of transmission surpassed normal data range, just prove that patient's state of an illness has aggravated, and the doctor can make corresponding solution immediately and control the state of an illness, prevents that the state of an illness from worsening once again.

The system does not need to have too high precision as a high-end system, and as a set of low-cost infectious disease room monitoring system, the monitoring is required to be completed within controllable cost, so that the condition of the patient is monitored by selecting the indoor environment and the posture characteristics of the patient. Infectious diseases are common diseases in life, so in an infectious disease room monitoring system, whether the condition of a patient is affected or not can be judged according to the environment in a ward. Of course, it is obviously unreliable to judge the disease condition of the patient only by depending on the environment of the ward, if a group of data higher or lower than the normal data appears in the data due to weather, the condition of the patient is judged to be aggravated by mistake, so the environment of the ward can only be used as a factor for judging the disease condition of the patient, and a series of other judgments are needed to judge whether the disease condition is really aggravated or not. The detection of the heart rate and blood oxygen of the patient is also one of the means for judging whether the patient's condition is aggravated, if the heart rate and blood oxygen data are too high or too low, the condition of the patient is proved to be worsened, and then the doctor can control the condition of the patient by adopting a series of means for the first time.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
