Summary of the invention
A kind of portable mobile wireless monitoring system low-power consumption implementation method, adopt part of data acquisition and data processing, the display part method for designing of separating as a result, with wireless connections is tie, ingenious maintenance data collecting part---the wireless monitor terminal module has reset function, reset output signal is converted into the drive signal of module controls part, thereby controls the running status of this terminal module.The control module part is a core with a timer circuit, under no reset signal driving situation, periodically export low (t1 time) level, height (t2 time) level, control wireless monitor terminal can be done periodically conversion with resting state in working order, reaches the purpose that reduces power consumption.Central processing unit can be under wireless on-state at any time by the mode that the sends order wireless monitor terminal that resets, if send reset command in the time to the wireless monitor terminal at t1, just can be so that the timer control section of wireless monitor terminal resets, thereby make terminal remain on the operating state in the t1 time, and can not enter resting state.Data acquisition, the intensity transmission of wireless monitor terminal also can be strengthened and weaken to central processing unit by the mode that sends order, as sample frequency, and transmission code rate etc.
The wireless monitor terminal possesses data acquisition module, wireless transport module and timercontrol module.The reset drives of timercontrol module comes from the output that resets of data acquisition module, and the homing action of data acquisition module sends reset command by the wireless connections approach automatically under certain condition by central processing unit and finishes via wireless transport module.When reset command from the wireless transport module to the data acquisition module, data acquisition module is carried out and to be resetted.When the data acquisition module execution resets, the periodic sampling signal meeting short interruption of data acquisition module, this periodic sampling signal is drawn out to a single-shot trigger circuit, and monostable time (t＞t suitably is set
S, t represents monostable time, t
SThe expression sampling period) just can just often export stable level, when the periodic sampling Signal Terminal, obtain the reset drives of a pulse signal output as the timer circuit part at the periodic sampling signal.
Central processing unit is carried out the acceptance of data, calculation process, the result shows, judge according to data processed result, when wireless terminal module by signal normal (amount of information is few), central processing unit sends the data acquisition that order weakens the wireless monitor terminal module, intensity transmission, by the time the wireless monitor terminal is passed through the resting state that the t1 time service enters the t2 time, wireless connections disconnect, central processing unit also enters the dormancy of t2 time, central processing unit active repetitive requests is connected until successful connection with the wireless monitor terminal afterwards, send a reset command subsequently and it resetted to the wireless monitor terminal, with reach that wireless monitor terminal and central processing unit state rotate synchronously; When wireless terminal abnormal signal (containing much information), central processing unit sends a command to the wireless test terminal and strengthens data acquisition, intensity transmission, and make the wireless monitor terminal reset sending reset command in the time period less than t1, can not enter the resting state of t2 time, the system that reaches uninterruptedly monitors.
As a kind of indefiniteness example, we have designed the wireless monitoring of pulse of a portable low power-consumption system according to above mentality of designing.As central processing unit, the wireless monitor terminal is made up of blood oxygen module, bluetooth module, timercontrol module with mobile phone in this system, and the bluetooth connected mode is adopted in mobile phone and test terminal.And with the specific design example of this system as patent.
