Detailed Description

The invention is further illustrated by the following examples, but is not limited thereto.

Example 1

Personal emergency system with active call function as shown in fig. 1, characterized in that the system comprises a wearing unit (1) and an emergency management center receiving and talking unit (2), wherein,

the wearing unit (1) comprises:

a human body parameter monitoring and early warning device (11);

one-way active call device or two-way active call conversation device (12) and

a positioning device (13); and

the emergency management center receiving and calling unit (2) comprises a receiving and calling device (21);

wherein, the human body parameter monitoring and early warning device (11) is connected with a one-way active calling device or a two-way active calling and talking device (12);

the one-way active calling device or the two-way active calling and talking device (12) is connected with a receiving and talking device (21) in the emergency management center receiving and talking unit (2);

the positioning device (13) is connected with a receiving and calling device (21) in the emergency management center receiving and calling unit (2).

Referring to fig. 1, an emergency automatic call personal system includes a monitoring device for monitoring parameters including heart rate, blood pressure, body temperature, blood oxygen saturation, acceleration due to gravity, horizontal acceleration, etc.;

a GPS positioning device; actively calling a two-way voice communication device GPS positioning device: is a built-in chip, typically provided by a professional GPS chip provider; the device utilizes WiFi and a built-in nine-axis gyroscope, combines the direction of a compass according to the motion data of a user, and accordingly realizes track query in a state without a network or a GPS.

The one-way active calling device or the two-way active calling and talking device (12) is a device which can send the monitored data to the receiving and talking device (21) when the parameter monitoring and early warning device (11) detects that the data of the wearer is lower than the preset data or is a device which directly carries out one-key remote connection to the receiving and talking device (21) to realize the talking with the rescuer when the wearer feels uncomfortable; preferably a photodetector.

The human body parameter monitoring and early warning device (11) integrates various parameters on one device. The human parameter monitoring and early warning device (11) photoelectric detector converts the red light and infrared light detected to penetrate through the artery blood vessel of the contact (non-contact) part into electric signals; because the absorption coefficients of skin, muscle, fat, venous blood, pigment and bone to two kinds of light are constant, only the concentration of hemoglobin and oxygenated hemoglobin in arterial blood flow changes periodically along with the artery of blood, so that the signal intensity output by the photoelectric detector changes periodically along with the change, and the corresponding blood oxygen saturation can be obtained after the signals with periodic changes are processed, and meanwhile, the pulse rate and the body temperature are calculated.

Heart rate, blood pressure, body temperature, and blood oxygen saturation are all vital sign parameters. The heart rate and blood pressure parameters are changed according to the physiological change, the psychological change and the emotional change of the human body. When people are highly stressed, the heart rate and blood pressure change can exceed the normal range. Besides the diseases, there are emotional changes such as fear and tension. When the phenomenon occurs, the system collects information, even if a user does not have a chance to send a help-seeking signal, the system can automatically dial the fixed number to call a service worker, the two-way voice communication service worker can know the existing situation of the user, if the situation is judged to be dangerous, the position of the user can be informed in time through the GPS, and the rescue worker can be dispatched in time. When the user does not change the speaking, the surrounding personnel service desk is informed that the user is rescued. Avoid the development of the situation.

The body temperature and the blood oxygen saturation parameters are basically not greatly changed by the emotion change of a user, but can be changed when the human body suffers from sudden diseases. The body will be heated when there is inflammation, and the oxygen saturation of blood will be reduced when breathing is not smooth. When the system monitors that the temperature of the human body exceeds the normal value, the system automatically reports the temperature to the service desk, and service personnel can inform the service personnel of seeking medical advice in time. If the body temperature continuously drops, the system is automatically monitored and then is timely communicated with the service desk. The service personnel can inquire the condition of the user, and the response is inquired in time and is processed in time. And the person without the response service timely contacts the related person to carry out rescue. After the blood oxygen saturation is reduced, vital signs are threatened, and parameters are reduced due to night breathing disorder, coal gas poisoning, lung diseases, toxic gas and the like. When the index is lower than that of normal person, the system calls the service desk automatically, and the service person communicates with the user in time. Avoiding the poisoning of people in sleep and the like caused by respiratory disturbance, coal gas poisoning and toxic gas. The service personnel can timely remind the user to quickly respond and keep away from the predicament. When the user does not respond, the service personnel can make a rescue response in time.

Four important parameters of four human vital signs of heart rate, blood pressure, body temperature and blood oxygen saturation are integrated, and the actual condition of a human body can be effectively judged in the process of comprehensively judging the functions of the human body. The heart rate is increased, the blood oxygen is increased, and the blood oxygen saturation is 100%. The system ensures that the call is not carried out in a normal range by calculating the movement frequency. The human body is in a disease state due to the rise of heart rate, blood pressure and body temperature, and the system automatically calls the service desk. The attendant will inform the user that he should seek medical advice. If the call is not answered, the service personnel can take rescue measures in time. Heart rate reduction, blood pressure reduction, oxyhemoglobin saturation reduction, user's vital sign receive the threat, and the system is automatic calls the service desk, and service personnel in time communicate with the user. If no response is made, the service personnel can take rescue measures in time.

Gravity acceleration, horizontal acceleration monitoring devices. The two parameters of gravity acceleration and horizontal acceleration indicate the motion state of the moving object, and the two parameters are mainly monitored by a sporter and a vehicle driver.

When the gravitational acceleration changes sharply, the basic condition is a fall. And the user may lose consciousness or be unable to take other help calling modes after falling down in different environments. When the emergency automatic calling personal system user system is used, the service desk can be automatically called, and the service personnel can quickly respond to the emergency automatic calling personal system user system for treatment after communicating with the emergency automatic calling personal system user system. And when no response exists, taking rescue measures in time.

When the horizontal movement is accelerated to exceed the normal change of a human body, the horizontal movement can fall down, be taken away by a high-speed moving object, be knocked out by the high-speed object, collide the moving object to a static object and the like during running. The system automatically reports to the service desk, and the service personnel can communicate with the user quickly, if no response is made, the service personnel can take rescue measures quickly.

Heart rate, blood pressure, body temperature, and blood oxygen saturation are all vital sign parameters. The heart rate and blood pressure parameters are changed according to the physiological change, the psychological change and the emotional change of the human body. When people are highly stressed, the heart rate and blood pressure change can exceed the normal range. Besides the diseases, there are emotional changes such as fear and tension.

The body temperature and the blood oxygen saturation parameters are basically not greatly changed by the emotion change of a user, but can be changed when the human body suffers from sudden diseases. The body will be heated when there is inflammation, and the oxygen saturation of blood will be reduced when breathing is not smooth. When the system monitors that the temperature of the human body exceeds the normal value, the system automatically reports the temperature to the service desk, and service personnel can inform the service personnel of seeking medical advice in time. If the body temperature continuously drops, the system is automatically monitored and then is timely communicated with the service desk. The service personnel can inquire the condition of the user, and the response is inquired in time and is processed in time. And the person without the response service timely contacts the related person to carry out rescue. After the blood oxygen saturation is reduced, vital signs are threatened, and parameters are reduced due to night breathing disorder, coal gas poisoning, lung diseases, toxic gas and the like. When the index is lower than that of normal person, the system calls the service desk automatically, and the service person communicates with the user in time.
