Refering to Fig. 7, step S61 can specifically be implemented as follows:
Step S611: judging whether the intensity in magnetic field is lower than the second preset strength threshold value, if so, thening follow the steps S612.
Second preset strength threshold value can be arranged according to the actual situation, as an example, the second preset strength threshold value can be with
For 2000 Gausses, 1500 Gausses etc., present embodiment is not particularly limited herein.
Step S612: the intensity for further obtaining magnetic field is lower than the duration of the second preset strength threshold value.
When the intensity in magnetic field is lower than the second preset strength threshold value, the intensity for further obtaining magnetic field is default lower than second strong
Spend the duration of threshold value.
Step S613: judge whether duration is greater than the second preset duration threshold value.
Second preset duration threshold value can be arranged according to the actual situation, as an example, the second preset duration threshold value can be with
It is set as 10 seconds, 15 seconds etc., present embodiment is not particularly limited herein.
In an implement scene, if step S613 " judging whether duration is greater than the second preset duration threshold value " is sentenced
Disconnected result be it is yes, then can further execute following step S614:

Step S82: output restores the instruction of the motor 20 of operating infusion pump and releases alarm.
If judging, motor 20, phase monitoring unit 30 cooperate processor to carry out the self-detection result of self-test as qualification, then it represents that
Motor 20, phase monitoring unit 30 be not affected by environment or institute is impacted smaller, within the acceptable range, and is unlikely to influence
The normal operation of motor 20, phase monitoring unit 30, can restore at this time operate infusion pump motor 20 and release alarm, with after
Continuous infusion.
Step S83: the step of instruction for exporting the motor 20 of locked infusion pump is continued to execute.
If judging, motor 20, phase monitoring unit 30 cooperate the self-detection result of processor progress self-test to be unqualified, table
Show motor 20, phase monitoring unit 30 it is affected by environment so that influence motor 20, phase monitoring unit 30 normal operation, this
When can continue to execute the step of instruction for exporting the motor 20 of locked infusion pump.
By the above-mentioned means, if motor 20, phase monitoring unit 30 self-test qualification, can restore the electricity for operating infusion pump
Machine 20, the step of otherwise continuing to execute the instruction for exporting the motor 20 of locked infusion pump, to guarantee infusion safety as much as possible.
