Description
Technical Field
The utility model relates to the technical field of medical equipment, more specifically relates to a two CPU fault monitoring of breathing machine and safety protection system.
Background
The breathing machine is used as life support equipment, and is required to have extremely high safety protection capability, and along with the attention of people to the safety of the breathing machine, the breathing machine is required to have a reliable detection alarm system under the condition of single fault. In the prior art, a single module is mostly adopted as a control unit, control and monitoring are integrated in the same module, and when a respirator breaks down, an alarm can be given. However, when the hardware or software of the module is abnormal, the system is often difficult to detect, and an alarm cannot be provided, so that certain potential safety hazard can be generated. In view of this, the utility model discloses it is suitable for now to come up with.
SUMMERY OF THE UTILITY MODEL
The utility model provides a to prior art not enough, the utility model provides a two CPU fault monitoring of breathing machine and safety protection system adopts bimodulus work, can detect various abnormal conditions, realizes that the trouble judges and reports to the police.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a two CPU fault monitoring of breathing machine and safety protection system, includes the host computer, the host computer is connected with main control module and auxiliary control module, main control module is as the main control part, controls the whole operation of breathing machine, auxiliary control module monitors as monitoring module instruction and each parameter of breathing machine that the host computer was issued, auxiliary control module connects fault alarm device and safety protection device.
Furthermore, the upper computer sends all parameter alarm information set by the breathing machine to the main control module and the auxiliary control module simultaneously through the CAN bus.
Further, the main control module and the auxiliary control module simultaneously acquire parameter data of all subsections of the breathing machine.
The upper computer sends the currently set inhalation pressure, exhalation pressure, mode, oxygen concentration and alarm setting information to the main control module and the auxiliary control module simultaneously through the CAN bus. After the main control module obtains the parameters, the operation is started, and the main module and the auxiliary module can simultaneously acquire the data parameters of the near-end pressure sensor, the far-end pressure sensor, the oxygen concentration sensor, the oxygen flow meter and the air flow meter. The auxiliary control module is used for comparing the set parameters with the acquired sensor data, detecting whether the current state is abnormal or not, if so, starting a safety protection device, namely a safety relief valve for protection, and starting a fault alarm device for auxiliary alarm.
To sum up, the utility model discloses a bimodulus work, the primary module is as the main control part, and control breathing machine whole operation, supplementary module are as monitoring the module, monitor the instruction that the host computer was issued and the data of each sensor, under the discovery abnormal conditions, carry out the safety protection measure, open safety relief valve and start the warning. The utility model discloses can monitor the various abnormal conditions that main control board oneself can not be detected such as main control board sensor AD circuit abnormity, main control board control logic are unusual, main control board crashes.

Detailed Description
The present invention will be further described with reference to fig. 1, which shows a dual CPU failure monitoring and safety protection system for a ventilator.
The utility model provides a two CPU fault monitoring of breathing machine and safety protection system, includes the host computer, the host computer is connected with main control module and auxiliary control module, main control module is as the main control part, controls the whole operation of breathing machine, auxiliary control module monitors as monitoring module instruction and each parameter of breathing machine that the host computer was issued, auxiliary control module connects fault alarm device and safety protection device.
Preferably, in this embodiment, the upper computer sends each parameter alarm information set by the breathing machine to the main control module and the auxiliary control module simultaneously through the CAN bus.
Preferably, in this embodiment, the main control module and the auxiliary control module simultaneously acquire parameter data of each subsection of the ventilator.
The upper computer sends the currently set inhalation pressure, exhalation pressure, mode, oxygen concentration and alarm setting information to the main control module and the auxiliary control module simultaneously through the CAN bus. After the main control module obtains the parameters, the operation is started, and the main module and the auxiliary module can simultaneously acquire the data parameters of the near-end pressure sensor, the far-end pressure sensor, the oxygen concentration sensor, the oxygen flow meter and the air flow meter. The auxiliary control module is used for comparing the set parameters with the acquired sensor data, detecting whether the current state is abnormal or not, if so, starting a safety protection device, namely a safety relief valve for protection, and starting a fault alarm device for auxiliary alarm.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
