(4) and (3) detecting an alarm condition: when the following judgment conditions are met, the processing module 4 sends out an alarm control signal:
the distance measuring module 8 detects that the distance between the user and the grip 1 tends to gradually decrease from large, the pressure measuring module 9 detects that the pressure signal tends to gradually increase from small, the heart rate monitoring module 10 tends to have abnormal fluctuation, the processing module 4 calculates that the stress threshold value is close to the preset threshold value according to the angle measured by the accelerometer 81 in the distance measuring module 8, and the processing module 4 sends an alarm control signal when the four conditions are met;
(5) controlling and alarming: the alarm control signal sent by the processing module 4 causes the alarm module 13 to generate an alarm signal.
The invention provides an intelligent crutch with a stooping pain threshold prediction alarm function, which utilizes a distance measuring module, a pressure measuring module and a heart rate monitoring module to collect signals in real time, a processing module judges whether a user is in a stooping posture or not according to the real-time change trend of the collected signals, calculates the stress value of the lumbar vertebra of the user according to the angle measured by an accelerometer in the distance measuring module on the basis that the user is in the stooping posture, compares the stress value with a preset threshold in a storage module, and triggers an alarm module to remind the user to adjust the stooping posture in time if the stress value obtained by calculation is gradually close to the preset threshold; the alarm signal is automatically ended after being maintained for three seconds, and the alarm signal can be manually turned off through the key module.
According to the invention, through the mutual coordination work among the sensor group, the processing module and the storage module, the steps of information acquisition, alarm condition detection, control alarm and the like are automatically completed, a user only needs to adjust to a correct stooping posture according to the prompt of an alarm signal, the operation is simple and convenient, and the probability of occurrence of sudden conditions caused by lumbar pain due to incorrect stooping posture of the user suffering from lumbar diseases in daily life can be reduced.
