[0064] This embodiment can provide heat, humidity and oxygen to end users in plateau areas, meeting the demand for indoor comprehensive regulation.

[0065] This embodiment includes modules: oxygen source module, heating module, evaporative humidification module, monitoring module. This embodiment uses the oxygen source module to prepare oxygen by pressure swing adsorption, which can continuously supply oxygen to the room. In the case of varying oxygen demand, the oxygen supply can be easily adjusted to achieve effective oxygen supply. The use of the heating module and the evaporative humidification module can adjust the temperature and humidity of the indoor area where the personnel are located, realizing the combined supply of heat, humidity and oxygen.

[0067] The heating module comprises a heating wire, a heating wire temperature sensor, an outlet temperature sensor, a silicon controlled rectifier, a temperature controller and a control circuit; the heating wire temperature sensor serves as an over-temperature protection function to prevent the heating wire from being damaged due to excessively high temperature; the outlet temperature sensor serves as a temperature feedback function for the heated gas; the temperature controller is used for adjusting the output power of the silicon controlled rectifier, so as to realize temperature control of the heating wire; the gas subjected to temperature control and adjustment enters the evaporation and humidification module.

[0068] The evaporation and humidification module comprises a high-pressure heating micro-mist module, a temperature sensor, a pressure sensor and a humidity sensor; high-pressure water vapor processed by the high-pressure micro-mist module is sprayed into a humidification cavity to adjust the humidity of the gas; the high-pressure heating micro-mist module comprises a water processor, an inlet electromagnetic valve, a liquid level controller, an electric heating constant temperature controller, a three-way combination valve, a temperature sensor, a frequency converter, a variable frequency motor, a pressure transmitter, a high-pressure electromagnetic valve, a high-pressure super-micro atomizing nozzle group and a controller; purified water after water treatment enters the humidification cavity; the lower part of the humidification cavity is used for storing the purified water after purification by the water processor; the liquid level controller and the inlet electromagnetic valve are used to ensure that the water level of the water storage pool is within a safe range; the water storage part has the electric heating constant temperature controller; the heated water is pumped to raise the pressure of the water in the pipeline to a sufficient pressure; the high-pressure water reaches the high-pressure super-micro atomizing nozzle group.

[0070] Since there is a demand for oxygen supply throughout the year in plateau areas, there is a demand for oxygen supply, humidification and heating in winter; in summer, the relative humidity and temperature can meet the comfort requirements of indoor personnel, and only the demand for oxygen supply exists. In winter, the oxygen source module, the heating module and the evaporation and humidification module are started. In summer, only the oxygen source module is started, the prepared oxygen is mixed with air, and then the mixed air is directly introduced into the room without humidification and heating.

[0071] The control method flow chart is the combined working mode of each module in the embodiment.

The feedback control is used to correct the error of the feedforward control, and to maintain the stability and accuracy of the system.

The sensors are responsible for monitoring the flow rate and temperature signals of the fluid or gas and converting them into electrical signals. The actuators adjust the state of the control elements (such as valves, pumps, heaters) according to the instructions of the controller, thereby changing the flow rate and temperature of the fluid or gas. The controller receives the feedback signals from the sensors and makes decisions based on the pre-set control strategy, and then sends control signals to the actuators to achieve flow regulation.

[0073] The control structure of the controller includes three main components: feedback loop, control algorithm and actuator. The feedback loop is used to monitor the flow rate and temperature in real time, which is composed of sensors and related signal processing circuits. The sensors obtain the information of the fluid or gas flow rate, temperature and humidity, and then feed back the data to the controller. The controller processes the sensor data using the control algorithm and generates the corresponding control signal based on the pre-set control strategy. The actuator is responsible for adjusting the control elements according to the control signal, thereby achieving control of the flow rate, temperature and humidity. The fuzzy PID control strategy is combined to complete the precise control of the temperature, humidity and flow rate of the oxygen supply system. The indoor temperature, humidity and oxygen regulation control principle block diagram is shown in Fig. 3 .

[0074] In summary, the present application integrates the oxygen supply and ventilation, temperature and humidity modules, so that when there is a demand for heating, oxygen supply and humidification in the plateau indoor environment, the environment in the plateau indoor environment can be comprehensively regulated. Due to the comprehensive regulation, the coupling effect of oxygen supply and ventilation, temperature and humidity in single regulation is avoided, so that the indoor state can more accurately reach the required oxygen concentration, temperature and humidity state, and therefore the present application has wide application prospects.
