Packet length: the byte number length of entire data packet, including the packet header and the packet tail；
Data: for the expression of the concrete meaning of instruction described in the command code, data length is 0-10 byte, described
Expression matching on ASCii table is specific value, and described value is converted into 16 systems and carries out content expression；
Verification and: the cumulative summation of the command code, the packet length and the data length；
Packet tail: content is fixed as " 0x7E ".
Specifically, byte align therein is the storage mode of system, run according to the internal mechanism of system.
Further, the value range of special value described in the command code is 0x01-0x06, wherein specific value
Meaning are as follows:
0x01: instruction of shaking hands, after the completion of power-up initializing, described instruction content is " Hand ",；
0x02: target pressure value instruction, described instruction content are the expression of number or corresponding standard；It is repaired when as needed
When changing breathing output pressure value parameter, main MCU1 is instructed to from MCU2 by this and is sent target pressure value；
0x03: mode instruction, described instruction content are the expression of number or corresponding standard；When the different Working mould of selection
When formula, such as single horizontal or double horizontal patterns, corresponding turbine control program is also different, issues from main MCU1 to from MCU2；
0x04: real-time output pressure value instruction, described instruction content are the expression of number or corresponding standard；It is described real-time
Output pressure value is that main MCU1 collects real-time pressure output value, is issued from main MCU1 to from MCU2；
0x05: described from MCU2 replying instruction, described instruction content is " OK "；When the finger of shaking hands that the main MCU1 is sent
It enables, it is described that the instruction replied from MCU2 when can be normally received is received from MCU2；
0x06: described from MCU2 replying instruction, described instruction content is " ERROR "；It is primarily directed to the main MCU1
The instruction of shaking hands issued, it is described to carry out replying instruction from MCU2 when shaking hands failed；It is described to shake hands not successfully as the verification
With it is incorrect.
Further, the turbine control module in this system is PID controller, be can be realized when the main MCU1 is passed
It is described when the defeated corresponding target pressure value instruction that comes, the mode instruction, real-time output pressure value instruction
PID controller can automatically adjust according to corresponding demand, control the turbine.Here it should be noted that according to the mesh
The corresponding turbo-driven behaviour of control is made in mark pressure value instruction, the mode instruction, the real-time output pressure value instruction
To make, is not limited to the PID controller, turbine control module of the present invention can be an existing independent control device,
It is also possible to split type control device.
Preferably, in further implement, the main MCU1 and described from being also attached by I/O mouthfuls between MCU2,
It is mainly used for, carries out standby docking, after system operation when to be carried out data transmission, the main MCU1 can Xiang Suoshu
From MCU2 by the I/O mouthfuls of output high level, and then data command can be transmitted；The main MCU1 is received from MCU2 when described
After the high level of transmission, within the first predetermined time, corresponding data command is not received, then issues communication failure alarm letter
Breath.In actual operation, first predetermined time can be set as 30 seconds, 45 seconds, 1 minute etc..
Embodiment 2
Also referring to attached drawing 3, the present invention provides a kind of control method of Breathing Suppotion device systems, comprising steps of
S100, machine power on, and initialize to system soft and hardware；
S200, the main MCU1 issue instruction of shaking hands from MCU2 to described；
S300, after shaking hands successfully, the main MCU1 by module objectives pressure value instruct and mode instruction be sent to it is described from
MCU2；
After S400, system starts, the main MCU1 sends real-time output pressure value instruction to described from MCU2 in real time；
S500, it described is instructed from MCU2 according to the target pressure value instruction received and the real-time output pressure value
Turbine is controlled.
This method is independent by the control work of turbine, and the calculation resources of the main MCU1 are vacant, in this way described
When the other function of main MCU1 control system, so that it may which enhanced convenience is quick, so that it may accomplish effectively to control.It uses
The technical solution that double MCU are controlled can carry out turbine most important in Breathing Suppotion equipment by an individual MCU
Control, other system control tasks are put into another MCU, independent MCU to the control speed of turbine faster, it is more acurrate,
It can accomplish that the optimal resource of MCU all supplies turbine control, promote the control performance of turbine, and then optimize Breathing Suppotion equipment sheet
The performance of body.
Further, in step S300, further includes:
If the first pre-determined number is shaken hands, the failed or described main MCU1 is issued after data command in the second predetermined time not
Any reply is received, then operation is resetted to described execute from MCU2, after reset, the main MCU1 is issued to described from MCU2 again
It shakes hands instruction, if the second pre-determined number is still shaken hands failed after resetting, issues Communications failure alarm.Specifically in an implementation, institute
The value range for stating pre-determined number is set as 5-10 times；The value range of second pre-determined number is 2-5 times；Described second is pre-
The value range fixed time is set as 30-90 seconds.
Preferably, continuously receive 5 times as main MCU1 described in from the feedback command of MCU2 be " ERROR ", or work as main MCU1
Any instruction is not received in 1 minute after to the sending instruction from MCU2 to reply, then is resetted to described from MCU2, and carry out
Carrying out shake communication again issues master and slave MCU2 Communications failure alarm if continuously resetting success of not shaking hands yet three times.
The method that further can be determined that communication failure is in the step S200 further include:
The main MCU1 by I/O1 mouthfuls to it is described from the I/O2 mouth of MCU2 export high level, if it is described from MCU2 first
It is not received by the data command of the main MCU1 in predetermined time, then issues Communications failure alarm.
