Description
Technical field
The present invention relates to medical supplies equipment technical fields, and in particular to the oxygen uptake charge system based on Internet of Things.
Background technique
In present hospital ward, leads on each bed and be both provided with oxygen output equipment, and tied by oxygen flow meter
It calculates and uses the time, to calculate expense.However passing this set the problem is that: 1. due to each bed oxygen flow
Meter is all independently arranged, and charging personnel want to know about the oxygen service condition of each bed, need manual patrol ward, copy one by one
Record oxygen flow meter real-time condition, must periodical inspection, record period variation, cause charging task heavy, take time and effort.2.
The uncertainty of bed oxygen uptake demand, when patient, stop when opening, and equipment laws of use is different, if using networking monitoring means, if
Situations such as standby necessary timing (relatively frequently) carries out Network Synchronization, causes power consumption increase, shorter battery life.3. hospital bed
Position is numerous, and floor structure rise is from remote, environment is complicated, the oxygen flowmeter simultaneous transmission of signals of substantial amounts, if wiring, engineering
Amount is big and is related to ward transformation, if be easy to causeing coverage area insufficient, network efficiency is low using common radio connection
Under, or even generate the problems such as signal interferes with each other.4. charge accounting is opaque, the service condition of oxygen flowmeter, charging mode are only
Hospital unilaterally operates, and patient is difficult to understand the consumption of oneself in real time, is easy to produce doctor and patient information asymmetry, hinders
It links up.5. patient is in bed, family members are in sitting posture, it is difficult to observe oxygen flowmeter reading, need to stand up or close to etc. modes, adjustment
The viewing angle of people, and oxygen flowmeter can not be adjusted, to facilitate observation.
Summary of the invention
The present invention is provided and a kind of contacts each ward oxygen flow based on Internet of Things to solve the deficiency of above-mentioned technology
The oxygen uptake charge system of meter.
Technical solution of the present invention: the oxygen uptake charge system based on Internet of Things, including the exchange of oxygen flowmeter, floor Internet of Things
Machine and server, the metering expelling plate that the oxygen flowmeter is equipped with oxygen delivery outlet and connect with oxygen delivery outlet, the metering
Expelling plate is equipped with LORA wireless transmitter, battery and pressure sensor, and the metering expelling plate is detected by pressure sensor
Oxygen delivery outlet stream pressure is converted into data and is transmitted to floor switch of internet of things by LORA wireless transmitter, described
Data are uploaded to server by floor switch of internet of things.
By adopting the above technical scheme, when patient begins to use oxygen on bed, the oxygen delivery outlet of oxygen flowmeter starts defeated
Oxygen out, pressure sensor will sense that the stream pressure of oxygen delivery outlet changes and produce signal at this time, measure expelling plate
The signal is sent to This floor switch of internet of things by LORA wireless transmitter, and floor switch of internet of things receives number
According to rear, server is transmitted to by TCP network, clearing software starts Fare determined by travel time in server, otherwise pressure sensor detection is not
To stream pressure, charging stops.After being arranged in this way, patient can according to need random closing oxygen without notice.And charging people
Member also need not it is another one make an inspection tour record oxygen flowmeter service condition.Greatly easy action.
In view of on each hospital bed, the uncertainty that oxygen uses, each oxygen flow meter have oneself particular time,
Particular law.Such as on a bed patient update, whether oxygen use, and oxygen use time can all generate variation, even
The same patient can also correspond to generation and use variation in the different state of an illness stages.
Therefore, the present invention select LORA(LONG RANG), as between slave computer (oxygen flowmeter) and floor Internet of Things into
Row signal transmission plan.
Equipment timing is not needed in LoRa framework based on ALOHA and carries out Network Synchronization, is only had data in node
It is taken when transmission to Network Synchronization data.In the asynchronous frequency range of LoRa, end application accurately determines equipment
" suspend mode " time, therefore the battery capacity of equipment can be saved easily, extend the service life of device battery.And LORA high
Link budget up to 157dB makes its communication distance up to several kilometers (related with environment).It receives electric current only 10mA, sleep current
200nA, this delays the service life of battery significantly
LoRa uses linear frequency modulation spread spectrum modulation technique, while maintaining low-power consumption, hence it is evident that increase communication distance and network
Efficiency, and eliminate interference, reaches even if using identical frequency while will not generate transmission and interfere with each other.It is extremely applicable to cure
The case where distance is remote between institute's equipment, complex environment, and because oxygen flowmeter service condition, transmission be equipment enable,
Equipment closes signal simple in this way, only may need within one day to send several bytes, low for data rate requirement, avoids
The slower disadvantage of LORA transmission rate.
By the floor switch of internet of things of setting, the oxygen flowmeter of each floor substantial amounts is contacted into a local
Net, all of the port have the channel width exclusively enjoyed, to guarantee the fast and effective transmission of data on each port.
The further setting of the present invention: the oxygen uptake charge system further includes several oxygen streams of corresponding bed quantity setting
