Problems solved by technology

[0004] Now the respiratory support equipment on the market has only one MCU (Microcontroller Unit, micro control unit). In general use, there will be no problems. appears, then there will be inaccurate turbine control, prone to medical accidents
[0005] The patent document with the application number 201210581107.0 discloses a turbine controller, the main problem to be solved is: most of the turbine controllers are integrally sealed structures, and the mechanical size cannot be adjusted; it is difficult to match with other components
Moreover, the solution mainly realizes corresponding functions by connecting with a computer, and does not solve the problem of inaccurate turbine control if the core processor runs for a long time
[0006] Therefore, the turbine control scheme of the existing respiratory support equipment still needs to be improved and improved.

Embodiment 1

[0038] Please also refer to the attached Figure 1-2 , the present application provides a turbine control system, including a master MCU1 and a slave MCU2 that communicates with the master MCU1 according to a default protocol in two directions. Specifically, the slave MCU2 drives the turbine to work through the turbine control module according to the instruction of the master MCU1, and the master MCU1 is used for processing system tasks.

[0039] Specifically, the master MCU1 is responsible for controlling all the peripheral systems except the turbine, and the slave MCU2 is only responsible for controlling the turbine. Among the software tasks, the main MCU1 is responsible for controlling the storage tasks of respiratory support equipment, system alarm control tasks, network control tasks, respiratory state detection tasks, calibration control tasks, hardware alarm control tasks, display control tasks, real-time treatment control tasks, For the main tasks of system operation ...

Embodiment 2

[0059] Please also refer to the attached image 3 , the present invention provides a control method of a respiratory support equipment system, comprising the steps of:

[0060] S100, the machine is powered on, and the system software and hardware are initialized;

[0061] S200, the master MCU1 sends a handshake instruction to the slave MCU2;

[0062] S300. After the handshake is successful, the master MCU1 sends the module target pressure value instruction and mode instruction to the slave MCU2;

[0063] S400. After the system starts to work, the master MCU1 sends a real-time output pressure value command to the slave MCU2 in real time;

[0064] S500. The slave MCU2 controls the turbine according to the received target pressure value instruction and the real-time output pressure value instruction.

[0065] In this method, the control work of the turbine is separated, and the computing resources of the main MCU1 are spared, so that when the main MCU1 controls other functions...

Embodiment 3

[0072] The present invention also provides a technical solution of a respiratory support device, which mainly uses the control system in Embodiment 1 to work, and uses a dual-MCU control scheme for the respiratory support device, wherein the slave MCU2 is only responsible for controlling the PID control of the turbine, and the The master MCU1 is responsible for other control parts of the respiratory support equipment, and the master MCU1 communicates with the slave MCU2 through the serial port, so that the control speed of the turbine can be greatly increased, thereby improving the overall performance of the respiratory support equipment.

Abstract

The invention relates to the field of electric appliances, in particular to a turbine control system, a control method and a breathing support device. The turbine control system comprises a main MCU and a slave MCU which is in bidirectional communication with the main MCU according to a default protocol, wherein the main MCU is used for processing a system task; and the slave MCU is used for driving a turbine through a control module according to the instruction of the main MCU. Compared with the prior art, according to the turbine control system, the control method and the breathing support device, the slave MCU is only responsible for controlling the control of the turbine, the main MCU is responsible for other control parts of the system, the main MCU is in communication with the slaveMCU through a serial port, in this way, it can be ensured that in long-time operation of the system, then the overload operation of the main MCU is avoided, the situation of fault occurrence is avoided, the control speed of the turbine can be greatly improved, so that the overall performance of the breathing support equipment is improved.

Description

technical field [0001] The present application relates to the field of electronic devices, in particular to a turbine control system, a control method, and respiratory support equipment. Background technique [0002] Respiratory support equipment has been widely used as an effective means to replace or assist people's spontaneous ventilation function. Especially in some medical fields, it is widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support therapy and emergency recovery, and occupies a very important position in the field of modern medicine. [0003] At present, more and more sleep-type respiratory support devices are used in the family, so the requirements for the control performance of respiratory support devices are getting higher and higher. The most important control in respiratory support devices is Turbine control. [0004] Now the respiratory support equipment on the market has...
