Abstract

The invention designs a GPS/Beidou positioning alarm device and method special for the old. The device relates to satellite positioning, acceleration measurement and heart rate measurement technologies. With the increase of solitary old people, the situations of delaying treatment are more and more because of sudden diseases or accidents and the failure of calling for help in time. The existing GPS/Beidou positioning device only has a positioning function, and the device innovatively adds a manual alarm function and an automatic alarm function specially designed for the old. Firstly, the old man can realize manual alarm by pressing an alarm button. Secondly, an automatic alarm function is designed, alarm is carried out when the alarm exceeds a preset region based on position information, the alarm does not move for a long time when the position is in a moving state, and alarm is carried out when the heart rate is abnormal based on falling alarm of acceleration measurement and heart rate abnormal based on LED blood reflection. The heart rate recordings and activity traces will also be reported periodically for analysis and monitoring of the physical condition. The device wirelessly transmits information to a background server through the narrow-band Internet of things NB-LoT.

Description

Alarm device and method based on GPS/Beidou satellite

Technical Field

The invention relates to a GPS/Beidou satellite positioning, acceleration and heart rate measuring and alarming system and an implementation method.

Background

With the aging of the society, as solitary children are in employment and the solitary old people are more and more, the old people are ill suddenly and have no ability to call to alarm, and the condition of the old people is usually delayed because no relatives are at the side of the old people. The GPS/Beidou positioner on the market at present lacks an alarm function, and particularly has an automatic alarm function which is very important for the old people, so that a lot of old people can save lives in time in a rescue notebook, but the old people and children are in each party because precious rescue time is lost.

Disclosure of Invention

The invention aims to provide a device for monitoring body health, monitoring position and manually alarming and automatically alarming in abnormal conditions for the old, so that the old can be treated and helped in time when the health is abnormal or diseases occur suddenly.

The manual alarm can be triggered by pressing an alarm key by the old to alarm and whistle, a nursing staff is called, and the alarm is cancelled by pressing a cancel key.

The automatic alarm can be triggered by monitoring the old people's track by the GPS without moving for a long time, and indicates the incapability of the old people.

The automatic alarm can be triggered by monitoring the sudden increase of the acceleration through the gyroscope, so that the old can send a distress signal at the first time of falling.

The automatic alarm can monitor abnormal heart rate, trigger alarm and call for help in time, thereby gaining time for rescue.

The automatic alarm can monitor that the activity area of the old exceeds a preset range to trigger alarm, so that the old is prevented from being lost.

The health monitoring can be realized by periodically measuring the heart rate and monitoring the movement track, and the data are uploaded to a background database for analysis and early warning, so that the purpose of preventing the disease in the bud is realized.

The position information, the health information and the alarm information are all wirelessly transmitted to the background server through NB-LoT. And the background server sends the information according to a preset number.

Because the activities and the memory capacity of the old are limited, the solar charging function is added, and the electric energy supply of the positioning alarm device is ensured.

Detailed Description

The technical solution of the present invention will be described in detail below with reference to the drawings in the specification, and the described embodiment is only one embodiment of the present invention, not all embodiments, and all other embodiments similar to the embodiment belong to the protection scope of the present invention.

The invention provides a small portable device 2 integrating positioning, alarming and health monitoring for the old, a GPS/Beidou satellite navigation system 1 provides positioning information for the old, and a background server 23 provides map identification, information processing and forwarding for the old.

Fig. 1 depicts the whole working system and working principle block diagram, and each functional module of the device 2 can be divided into four layers according to signal input to output, namely a signal sensing layer 3, a signal calculating layer 4, a signal output layer 5 and a signal transmission layer 6. The sensing layer 3 receives positioning satellite signals, key signals 11 and 12, light intensity signals of the heart rate module 15 and acceleration signals of the gyroscope module 19 from the satellite navigation system 1 respectively, and sends the signals to the background server 23 for alarm threshold judgment and analysis after corresponding calculation processing.

The device positioning module 7 of the invention regularly receives positioning information sent by the GPS/Beidou positioning satellite 1, calculates the current longitude and latitude through the position and track calculation module 8 of the device, and can wirelessly send the current longitude and latitude to the background server 23 through the NB-LoT module 22. The NB-LoT technology has the characteristics of high gain, 20dB higher and lower power consumption than the prior art, and both sensitivity and battery life have advantages that are not comparable to other technologies.

Further, the alarm module 9 that the area and track of the device are not moved judges whether the current position of the device is within the preset moving range, and if the position information exceeds the preset moving range, an alarm prompt is immediately sent to the background server 23.

Further, the over-territory and track non-movement warning module 9 of the device monitors the position movement track, and if the position movement track is still not moved after the preset time, an alarm prompt is immediately sent to the background server 23. And when no abnormality occurs, reporting the position track to the background server 23 regularly.

The device has the functions of manual alarming and cancellation. After the alarm key 11 is pressed, the alarm information and the current position information are sent to the background server 23 through the NB-LoT module 22, and the background server 23 sends out an alarm prompt. The alarm can be cancelled by pressing the cancel key 12 according to a preset operation.

This device has the alarm function that falls. The gyroscope module 19 on the device measures acceleration, the angular displacement calculation module 20 judges whether the angle and the displacement are within a preset range in a short time, and if the angle and the displacement exceed a preset threshold, an alarm prompt is sent to the background server 23 through the NB-LoT.

The device has the functions of recording the heart rate and alarming for abnormalities. This device adopts the photoelectric method to measure the rhythm of the heart, wears the rhythm of the heart module 15 that is close to skin one side of the device on old man's wrist and is equipped with LED and photodiode, because the heart beats and arouses vascular blood flow periodic variation, further influences the reflection of the LED light that photodiode received also periodic variation thereupon to the rhythm of the heart has been measured.

Further, if the heart rate exceeds the preset range, an alarm prompt is immediately sent to the background server 23 through the NB-LoT. If there is no abnormality, the heart rate record is reported to the background server 23 periodically.

The device is matched with a solar charging device to provide electric energy. Since this part of the technology is mature, it is not stated.

This device is equipped with bee calling organ for whistle when reporting to the police. Since this part of the technology is mature, it is not stated.

Fig. 2 is an external view of the apparatus, the front of which is provided with a time information display screen 24 for displaying time and short messages, and a solar cell panel 25 for charging.

The background server 23 receives the alarm of the device of the present invention, sequentially alarms the preset notification objects according to the set alarm sequence, and transmits the related information.
