Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The embodiment of the invention discloses a motion state monitoring system based on wearable equipment, which is shown in fig. 1, and further comprises wearable equipment 120, an intelligent terminal 100 and a management and control center 110, wherein the wearable equipment 120 and the intelligent terminal 100 are positioned at a user side, and the management and control center 110 is composed of a cloud server or a remote server and the like, and the intelligent terminal 100 comprises intelligent equipment such as a smart phone and a tablet personal computer. The wearable device 120 is composed of at least one harness detection device, the harness detection device is used for detecting the motion state of a human body, the intelligent terminal 100 is in wireless connection with the harness detection device, the intelligent terminal 100 is mainly used for realizing interaction with the harness detection device, motion state information acquired by the harness detection device is transmitted to the management and control center 110, and when the abnormal motion state occurs, the management and control center 110 carries out risk management and control on the abnormal motion state and transmits the risk management and control information to the intelligent terminal 100.
The harness detection device mainly comprises various sensors such as an acceleration sensor, a positioning sensor and an early warning module, wherein the acceleration sensor can detect the change of the inclination angles of the upper part, the lower part, the left part and the right part, and is arranged on the harness detection device for detecting the movement gesture; the positioning sensor is mainly used for acquiring position information, and the early warning module can analyze and generate a risk prompt based on the motion gesture information acquired by the acceleration sensor and the position information and time information acquired by the positioning sensor so as to judge whether the motion state of a user is abnormal.
The early warning module of the harness detection device can also judge whether the motion state of the user is dangerous or not by analyzing the data of the positioning sensor alone. Such as sudden falls, i.e. falls in which the person takes very little time from normal to falling, especially unintentional slipping. The specific analysis process is as follows: defining a movement gesture in standing as a first gesture, defining a fallen gesture as a second gesture, wherein when the first gesture is positioned, the positioning data of the positioning sensor at least comprise a first time, a first height and a first longitude and latitude, and when the second gesture is positioned, the positioning data of the positioning sensor at least comprise a second time, a second height and a second longitude and latitude; when the user falls down, the early warning module judges whether the user falls down according to the time of switching from the first height of the first gesture to the second height of the second gesture and the longitude and latitude change, wherein the time of switching the gesture of the user is the time interval between the first time and the second time, and the longitude and latitude change of switching the gesture of the user is the difference between the first longitude and latitude and the second longitude and latitude. When the early warning module detects that the first height in the positioning data of the positioning sensor is suddenly changed to the second height, the time interval between the first time and the second time is extremely short, and in addition, the first longitude and the second latitude have obvious differences, the early warning module judges that the user falls down. The analysis method for the motion state introduces longitude and latitude change references while judging the height change of the user, avoids misjudgment of falling conditions caused by squatting and other operations, and has a good auxiliary judging function on the motion state generated by detecting the change of the inclination angles of the upper, lower, left and right sides by the acceleration sensor.
In addition to the above, the harness detection device may further be provided with a health detection module for detecting a health state of a human body, where the health detection module detects a physiological state of the human body including a body temperature, a heart rate, and the like, so as to assist in determining whether the exercise state is abnormal. The abnormal behavior is comprehensively judged by monitoring the health state of the human body and combining with the motion gesture information, the position information and the like, so that the accuracy of judging whether the motion state is the abnormal behavior is improved. Taking sudden falls as an example, a human body is frightened by sudden falls, and stress reactions such as abrupt heart rate acceleration, muscle tension, rapid blood pressure rise, abnormal brain wave excitation and the like can be generated, and the health parameter which can be detected by the health detection module at least comprises one of blood pressure, blood oxygen saturation, pulse, body temperature and brain wave. When the early warning module detects that the first height in the positioning data in the positioning sensor is suddenly changed to the second height, the time interval between the first time and the second time is extremely short, and in addition, when obvious differences exist between the first longitude and the second longitude and the latitude, the health detection module synchronously detects whether the human body generates stress reactions such as sudden acceleration of the heart rate, muscle tightness, rapid rising of the blood pressure, abnormal excitation of brain waves and the like, and sends the detection result to the early warning module. The early warning module comprehensively analyzes the positioning data and the health state of the human body, judges the motion state of the personnel by combining the motion posture information acquired by the acceleration sensor, and carries out motion risk early warning.

Each detection device can monitor the position, the movement action and the physiological condition of the person of the user, interact with the intelligent terminal through a communication protocol, and can provide corresponding movement state data for the management and control center 110. When detecting that the motion state of the user is abnormal, the harness detection device can send an abnormality prompt to the management and control center 110 by itself without user consent.
In the case where the matching relationship of the harness detection device and the person is confirmed through the harness seating check, the intelligent terminal 100 determines the current viewing direction of the person by combining the orientation of the head detection device 121, and determines the rationality of the current viewing direction and the movement direction based on the relationship between the current viewing direction and the movement directions of the first wrist detection device 123 and the second wrist detection device 124. When the relationship between the current viewing direction and the movement directions of the first wrist detection device 123 and the second wrist detection device 124 shows that the movement ranges of the person are in opposite directions to each other in the predetermined time zone, the working intelligent terminal reads the movement data of the first leg detection device 126 and the second leg detection device 127 to determine the relationship between the arm movement direction and the lower limb movement direction. At least three situations different from the current vision direction exist in the arm movement direction and the lower limb movement direction, and the intelligent terminal 100 sends out a tool positioning inspection reminding message to the management and control center 110. In response to the harness in-place inspection reminder message, the management and control center 110 can confirm the integrity of the harness detection devices according to the online state confirmed by the data uploading and analysis of the corresponding detection devices, and further confirm the integrity of the harness in an indirect manner, and can also achieve specific image acquisition for personnel by adjusting the monitoring direction of video monitoring, so as to further determine the integrity of the harness.
