Embodiment 1

[0042] For details, please refer to the attached figure 1 , the present invention provides a security system for respiratory support equipment, including a main processor module, a backup processor module, and a reset module; the main processor module is used to process system tasks when the system is working normally; the backup processor module The module is used to temporarily process the processing of the peripheral system control program of the device when the main processor module fails; the reset module is used to reset the main processor module when the main processor module fails reset. In this way, it can be guaranteed that even if the main processor module is in the failure state of crashing or program running away, the system will not stop running due to the failure of the processor, but can quickly eliminate the failure and ensure the normal operation of the equipment.

[0043] Specifically, the main processor module includes:

[0044] Main processor 11: used fo...

Embodiment 2

[0063] For details, please refer to the attached Figure 1-2 , the present invention also provides a control method for the security system, comprising the steps of:

[0064] S100, the system is powered on, and the main processor 11 and the backup processor 21 are reset;

[0065] S200, the standby processor 21 is on standby, and only communicates with the main processor 11 in two directions, and receives each other's heartbeat packets;

[0066] S300. According to whether the heartbeat packets of the main processor 11 and the backup processor 21 are abnormal, determine whether there is a fault, and execute a corresponding working mode.

[0067] Specifically, when the system is powered on, the first power supply circuit 13 supplies power to the first reset circuit 12, and the first reset circuit 12 resets the main processor 11; the second power supply circuit 23 supplies power to the second reset circuit 12. The circuit 22 supplies power, and the second reset circuit 22 resets...

Embodiment 3

[0070] The present invention also provides a respiratory support device using the security system in Embodiment 1.

[0071] Specifically, the reliability of the safe operation of respiratory support equipment can be guaranteed. Through the two-way communication between the main processor 11 and the backup processor 21, when a single processor fails, it can automatically switch to another processor, ensuring that the respiratory support equipment Support the continuity of equipment operation, effectively improve the safe operation of respiratory support equipment; reduce the possibility of performance degradation such as abnormal crashes and program runaways caused by external electromagnetic interference, and improve the ability to resist electromagnetic interference.

Abstract

The invention relates to a respiratory support equipment safety system, a control method and respiratory support equipment. A respiratory support equipment safety system comprises a main processor module, a standby processor module and a reset module. The main processor module comprises a main processor used for controlling normal operation of the system; a first reset circuit; a first power supply circuit; the standby processor module comprises a standby processor; a second reset circuit; a second power supply circuit; the reset module comprises a reset chip used for resetting the main processor; third power supply circuit. The system can be automatically switched to the standby processor when the main processor is in abnormal states such as crash and program runaway, so that the operation continuity of the equipment is ensured, and the safe operation of the respiratory support equipment is effectively improved; Meanwhile, the standby processor can realize automatic reset of the mainprocessor by controlling the reset chip, so that the risk of equipment failure caused by abnormal crash, program runaway and the like due to external electromagnetic interference is reduced to the minimum.

Description

technical field [0001] The invention relates to the field of electrical recognition, in particular to a security system for respiratory support equipment, a control method and respiratory support equipment. Background technique [0002] At present, there are more than 100 million COPD patients in my country, making it the third most common chronic disease in China after hypertension and diabetes. Positive pressure ventilation equipment, especially respiratory support equipment, has been widely used in hospitals and families as an effective means of adjuvant treatment of COPD. [0003] Respiratory support equipment is to compress the air at normal temperature and pressure to form a certain pressure and flow of gas, which is output to the user after passing through the humidification water box, so as to ensure that the breathing gas has a certain humidity and temperature, improve the comfort of use, and avoid complications happened. In order to ensure the safety of use, the ...
