The specific embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.Should be understood that following examples only are used to this utility model is described but not are used to limit scope of the present utility model.
Embodiment 1:
Accompanying drawing 1 is the module map of the control system that is used for respirator 100 of embodiment 1.
As shown in Figure 1, this control system 100 is made up of microcomputer portion 40 and ancillary equipment.Wherein, microcomputer portion 40 comprises ARM single-chip microcomputer 10, PIC single-chip microcomputer 20 and a data relief area 30.
ARM single-chip microcomputer 1 is the system of 32 RISC framework, speed of service height, and data-handling capacity is strong, and outside extended capability is also very strong, so it is as host CPU in this control system 100, is responsible for handling the incident of most complexity.On ARM single-chip microcomputer 10, hang with external RAM 54, external ROM 55, display driver 56, data flash memory 57, expand ancillary equipment such as input port 58 and expansion input port 59 by bus 53.
PIC single-chip microcomputer 20 is single-chip microcomputers of 8, and its speed of service is relatively slow, so be as subordinate CPU in system, is responsible for handling the simple event of fraction, monitors the ruuning situation of ARM single-chip microcomputer 10 simultaneously.On the port of PIC single-chip microcomputer 20, directly hang with keyboard 50 and pick off 51, the effect of keyboard 50 is for doctor's input operation instruction, the operation of control breathing machine, the effect of pick off 51 is to receive the signal relevant with patient's breathing, and be digital signal by an Analog to Digital Converter section 52 with analog-signal transitions, handle in the input PIC single-chip microcomputer 20.
Because ARM single-chip microcomputer 10 is systems of 3.3V, the ancillary equipment of hanging on its bus 53 is many, and program is externally to move among the ROM 55, data also are to be stored in the external RAM 54, so the capacity of resisting disturbance of ARM single-chip microcomputer 10 is poor, just be easy to cause program fleet (promptly crashing) in case be interfered on the bus 53, and then cause system crash.
Under comparing, PIC single-chip microcomputer 20 is systems of 5V, and ROM and RAM are built-in, and ancillary equipment is few, and the port driver ability of PIC single-chip microcomputer 20 is strong, so its capacity of resisting disturbance is higher than ARM single-chip microcomputer 10 far away.Experiment showed, and promptly use a powerful electronic equipment of energy abrupt release, such as high frequency electric knife, near the circuit part of PIC single-chip microcomputer 20, carry out the operation that electric knife is cut or coagulated then, make its abrupt release high-power, PIC single-chip microcomputer 20 still can not crash.And on ARM single-chip microcomputer 10, implement identical experiment, find that the probability of ARM single-chip microcomputer 10 deadlocks is very high.
ARM single-chip microcomputer 10 possesses communication module 11, timing module 12 and setting state module 13, and PIC single-chip microcomputer 20 possesses memory module 21, monitoring module 22, foldback module 23 and feedback module 24.
During operate as normal, the communication module 11 of ARM single-chip microcomputer 10 is sent communicating requirement 31 to PIC single-chip microcomputer 20, and carries out exchanges data with it, and the operational factor relevant with present running status sent to PIC single-chip microcomputer 20.
The memory module 21 of PIC single-chip microcomputer 20 receives the operational factor that is sended over by ARM single-chip microcomputer 10, and it is deposited in the built-in internal RAM 25.Because the data power down in the RAM is promptly lost, so the data in the internal RAM 25 will be initialised when 20 starts of PIC single-chip microcomputer automatically.
The process of whole communication is undertaken by data buffer zone 30.Specifically, ARM single-chip microcomputer 10 deposits operational factor in the data buffer zone 30 in earlier, sends communicating requirement 31 to PIC single-chip microcomputer 20 then.PIC single-chip microcomputer 20 reads out operational factor in data buffer zone 30 after receiving communicating requirement 31, and it is dumped in the internal RAM 25.
The effect of timing module 12 is frequencies of the above-mentioned communication of control, makes that the interval between twice communication is not more than a predefined value, and in the present embodiment, this value is 1 second.
Whether the above-mentioned communication of monitoring module 22 monitoring of PIC single-chip microcomputer 20 is carried out with the frequency of expection.If in 1 second, received communicating requirement next time, just think that ARM single-chip microcomputer 2 is in normal operating conditions.And all do not initiate communicating requirement next time in case surpass 1 second ARM single-chip microcomputer 10, just judge that ARM single-chip microcomputer 10 crashes, so send a reset signal 32 to it, makes ARM single-chip microcomputer 10 reset.
PIC single-chip microcomputer 20 also comprises a feedback module 24, and the effect of this feedback module 24 is after finishing the communication of being initiated by ARM single-chip microcomputer 10, initiates a feedback communication to ARM single-chip microcomputer 10.The process of this feedback communication is as follows: feedback module 24 feeds back to needs the data of ARM single-chip microcomputer 10, such as the instruction of doctor by keyboard 50 inputs, and the signal that receives of pick off 51 etc., deposit data buffer zone 30 in, send a feedback communication to ARM single-chip microcomputer 10 again and require 31, ARM single-chip microcomputer 10 reads data from data buffer zone 30 after receiving this feedback communication requirement 31.
The setting state module 13 of ARM single-chip microcomputer 10 possesses judge module 14, selftest module 15 and recovers module 16 formations.After resetting, setting state module 13 at first can send one to PIC single-chip microcomputer 20 and require signal, requires PIC single-chip microcomputer 20 to be provided at the preceding operational factor in the past that sends of deadlock.After obtaining these operational factors from PIC single-chip microcomputer 20, judge module 14 will judge that these operational factors are init states, or duty.If init state then is judged as electrification reset, start selftest module 15, carry out the self check flow process; If duty, judge then to crash in the position to reset, start and recover module 16, according to above-mentioned operational factor with the running status of ARM single-chip microcomputer 10 return to crash before identical, thereby can continue carry out work.Recover this process of running status originally from crashing to, the time is no more than 2 seconds, almost is inappreciable to patient's the influence that breathing produced.
In sum,, can crash hardly,, can improve the stability of The whole control system 100 so adopt PIC single-chip microcomputer 20 to be used as the house dog of ARM single-chip microcomputer 10 because the capacity of resisting disturbance of PIC single-chip microcomputer 20 is strong.And PIC single-chip microcomputer 20 can not only in time be given and reset signal 32 when ARM single-chip microcomputer 10 crashes, but also can tell that ARM single-chip microcomputer 10 is the deadlocks that take place under what state, thereby can make it return to original duty rapidly after resetting.Such as, if respirator is ventilated to patient before crashing, will continue after resetting so to be provided with to patient ventilating according to original parameter.Simultaneously, ARM single-chip microcomputer 10 can also judge that belonging to electrification reset still is to crash to reset according to the character of the state parameter that receives from PIC single-chip microcomputer 20.If electrification reset then carries out steps such as self check, and then enters duty according to the normal boot-strap flow process.
Embodiment 2:
In preamble, can not represent PIC single-chip microcomputer 20 can crash scarcely owing to external interference crashes hardly though proved PIC single-chip microcomputer 20 by experiment.Just in case PIC single-chip microcomputer 20 crashes, then in an embodiment, owing to be to adopt RAM to be used as memorizer, and the data power down that is stored among the RAM is promptly lost, these data all can be initialised when each PIC single-chip microcomputer 20 resetted.Therefore, just in case PIC single-chip microcomputer 20 also resets owing to crashing,, not only need to carry out startup self-detection, and can't return to the duty before resetting then will cause ARM single-chip microcomputer 10 also to enter the electrification reset pattern thereupon.
For further addressing the above problem, as shown in Figure 2, in the control system 100 ' of embodiment 2, change the memorizer in the memory module 21 into EEPROM 25 ' by internal RAM 25, it is EEPROM, and set up initialization module 26, be used for EEPROM 25 ' being carried out initialization in the normal shutdown flow process.Like this, even exist the unexpected power down of data among the EEPROM 25 ' also can not disappear.
Embodiment 2 only is with the difference of embodiment 1: PIC single-chip microcomputer 20 deposits the state parameter that receives in EEPROM 25 ', but not in the internal RAM 25 among the embodiment 1.After the start, PIC single-chip microcomputer 20 brings into operation, and system initialization, but the data in the EEPROM 25 ' can't be initialised still remains on the state before control system 100 ' the last outage.
PIC single-chip microcomputer 20 will be carried out the flow process of a normal shutdown if receive the shutdown command that is sent by the operator, and this flow process comprises one by the step of initialization module 26 with the data initialization in the EEPROM 25 ', and control system 100 ' is just closed then.
If PIC single-chip microcomputer 20 is to reset because of unexpected the deadlock, owing to do not receive shutdown command, will can not carry out last initialization step, thereby make the state parameter that still stores ARM single-chip microcomputer 10 received before resetting in the EEPROM 25 '.So, after PIC single-chip microcomputer 20 resetted, ARM single-chip microcomputer 10 also resetted thereupon, and can receive state parameter stored before resetting, thereby the state before making ARM single-chip microcomputer 10 and PIC single-chip microcomputer 20 to return to reset works on.
By adopting EEPROM 25 ' as memorizer, just can further avoid because the influence that 20 deadlocks of PIC single-chip microcomputer reset and cause, further improved the reliability of control system 100 '.
