Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. 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 electrocardio monitoring paste can be used for electrocardio collection and storage, can also be matched with handheld equipment for use, and is used for analyzing an electric signal on the APP of the handheld equipment, but is not processed in real time. Obviously, for the case of the imperative of the minute and the second, the real-time electrocardiograph monitoring and alarming have great advantages, and if early warning can be carried out in advance for a plurality of minutes or seconds, the rescue is very beneficial. Because the information on the electrocardiograph paste on the market requires related pairing equipment such as a mobile phone, a PAD or a computer, the information on the electrocardiograph paste can be transmitted to the Internet. Therefore, in some scenarios, in the absence of paired devices, anomalies and alarms are not sent in time, missing the optimal rescue time.

The embodiment of the invention provides an electrocardiograph monitoring system, which is used for acquiring electrocardiograph data of a wearer in real time through wearing equipment and analyzing the electrocardiograph data, and broadcasting an emergency help-seeking broadcast frame when the wearing equipment cannot be connected with a mobile terminal and the analysis result is that the electrocardiograph abnormal level of the wearer is a first level, so that the abnormal condition of the wearer is transmitted through the broadcast frame, and the effect of timely transmitting abnormal alarm information is achieved.

According to an embodiment of the present invention, there is provided an electrocardiographic monitoring system, as shown in fig. 1, including:

The wearable device comprises a wearable device 101, a first terminal 102 and a second terminal 103, wherein the first terminal is a pairing terminal of the wearable device.

The wearable device 101 is configured to collect electrocardiographic data of a wearer in real time, analyze the electrocardiographic data, and obtain an analysis result.

Under the condition that the wearable device 101 cannot be connected with the first terminal 102 and the analysis result shows that the electrocardiographic abnormality level of the wearer is the first level, broadcasting an emergency help-seeking broadcast frame, wherein the emergency help-seeking broadcast frame carries first alarm information, and determining that the electrocardiographic abnormality level of the wearer is the first level under the condition that the electrocardiographic abnormality level exceeds a preset level.

And the second terminal 103 is configured to identify the received broadcast frame, and obtain first alarm information in the emergency help-seeking broadcast frame when the received broadcast frame is identified as the emergency help-seeking broadcast frame, and perform corresponding processing based on the first alarm information, where the first alarm information includes wearer information and an electrocardiographic abnormality degree of the wearer.

In the application, the first terminal is a pairing device of the wearable device, for example, can be a mobile phone, a pad or a computer. The wearable device and the first terminal cannot be connected, for example, the first terminal paired with the wearable device can be forgotten to be carried by the wearer when the wearer goes out, or the first terminal paired with the wearable device can be powered off, etc.

In the present application, the second terminal may be any terminal other than the pairing device understood as the wearable device, for example, may be a mobile phone or a tablet of another person, or may be another wearable device worn by another person.

Illustratively, the first terminal may broadcast the emergency help broadcast frame via a bluetooth module. It will be appreciated that other wearable devices, mobile terminals, etc. within a preset range of the bluetooth module may receive the emergency help broadcast frame, where the preset range refers to a range in which bluetooth may communicate, and is illustratively 10 meters, 20 meters, etc. near the bluetooth module.

In the application, the second terminal carries out corresponding processing based on the first alarm information, and the second terminal can prompt the first alarm information so as to facilitate the holder of the second terminal to provide emergency help for the wearer of the wearing equipment based on the alarm information. Or the second terminal can forward the first alarm information to the target device according to the emergency help-seeking broadcast frame.

In an example, in the case that the second terminal is another wearable device, the second terminal may forward the first alarm information in the emergency help-seeking broadcast frame to its paired device, so that its paired device forwards the first alarm information to the target device, where the target device may be determined by the emergency help-seeking broadcast frame, and the target device may be understood as a device where the first alarm information needs to be sent, for example, may be a server corresponding to the wearable device (the wearable device that is disconnected from the first terminal), or another related device of the wearer of the wearable device, for example, a device subscribing to the health state of the wearer, for example, a device of the relative of the wearer.

Under the condition that the second terminal is other wearable equipment, the second terminal may be abnormally connected with the self pairing equipment, so that the second terminal can also broadcast the emergency help-seeking broadcast frame, and other equipment can forward the first alarm information in the emergency broadcast frame to the target terminal. The relevant forwarding operations may be real-time or periodic.

The degree that the electrocardio data exceeds the normal electrocardio data range exceeds the preset degree, namely the electrocardio abnormality degree exceeds the preset degree, and the electrocardio abnormality level of the wearer is judged to be a first level, namely the severity level. It should be noted that the preset degree is set by a technician.

In the present application, the wearer information may include personnel basic information, sudden disorder information, position information, and the like of the wearer.

Fig. 2 is a schematic diagram of a corresponding process performed by a second terminal based on first alarm information according to an embodiment of the present invention. It can be understood that, in fig. 2, the second terminal is taken as a wearable device of the same type, as shown in fig. 2, the second terminal may prompt the second terminal holder to provide assistance for a wearer with serious electrocardiographic abnormality based on the first alarm information, or broadcast an emergency help-seeking broadcast frame under the condition that the second terminal holder cannot provide assistance. In the case that the second terminal is connected with the terminal paired with the second terminal, the emergency help-seeking broadcast frame may be sent to the terminal paired with the second terminal, and the paired terminal may be sent to the Internet, and transmitted to the subscription device through the Internet. The first alarm information can be routed to the cloud end equipment and the data center for storage through the Internet. Other networks may be wired, wiFi, cellular communications, etc.

It should be further noted that, the wearable device of a different type may forward the received emergency help broadcast frame through its own emergency help broadcast frame forwarding function. If the wearable device of a different type is connected with the paired terminal, the received emergency help broadcast frame can be sent to the paired terminal, and the paired terminal performs further processing, such as forwarding to the paired device of the user or rebroadcasting.

Also, as an example, the second terminal may be a mobile terminal, where the mobile terminal receives the emergency help-seeking broadcast frame, and the mobile terminal holder may provide assistance to the wearer based on the first alarm information in the emergency help-seeking broadcast frame, or may send the emergency help-seeking broadcast frame to the subscribing device in response to a forwarding operation of the mobile terminal holder in a case where the mobile terminal holder cannot provide assistance. The first alarm information can be routed to cloud equipment and a data center corresponding to the wearable equipment through the Internet for storage.

In some optional embodiments, when the wearable device establishes connection with the first terminal and the analysis result indicates that the electrocardiograph abnormality occurs to the wearer, the wearable device is configured to send second alarm information to the first terminal through the bluetooth module, where the second alarm information includes electrocardiograph abnormality degree of the wearer; the first terminal is used for receiving the second alarm information and carrying out corresponding processing based on the second alarm information.

The wearable device can discover the first terminal by sending the broadcast frame through the Bluetooth module, and establishes connection with the first terminal. The wearable device establishes connection with the paired first terminal through the Bluetooth module, namely the wearable device can establish connection with the first terminal. At this time, if the analysis result indicates that the electrocardiograph abnormality occurs to the wearer, the wearable device sends second alarm information to the first terminal through the Bluetooth module.

It should be noted that, fig. 3 is a schematic diagram of a first terminal performing corresponding processing based on second alarm information according to an embodiment of the present invention, and as shown in fig. 3, the first terminal performing corresponding processing based on the second alarm information may include:

The first terminal sends the second alarm information to the Internet through other networks, and the second alarm information is transmitted to other subscription devices of the wearer of the wearable device through the Internet. The second alarm information can be routed to cloud equipment and a data center corresponding to the wearable equipment through the Internet for storage. Other networks may be wired, wiFi, cellular communications, etc.

In the present application, a subscribing device can be understood as a device that subscribes to a notification or broadcast of another device. For example, one device may broadcast information and another device may subscribe to the broadcasts to receive updates. In this case, the subscribing devices typically do not need prior pairing.

Subscription is divided into two types, one being a contact designated on the paired first terminal, this implementation being an APP implementation on the first terminal. The general flow is as follows: and after the APP receives the second alarm information, forwarding the second alarm information to the subscription equipment.

The other is sent to a subscribing device, such as a server of a pension/hospital, through an operations center. The general flow is that after receiving the second alarm information of the wearable device, the first terminal sends the second alarm information to the operation center server, and the server forwards the second alarm information to the interested subscription device, for example, a mobile phone, a mailbox, etc. of a guardian of the wearer according to the information of the subscription device.

Alternatively, in the present application, a subscribing device can also be understood as a target device.

In some optional embodiments, when the wearable device cannot be connected with the first terminal and the analysis result shows that the electrocardiographic abnormality level of the wearer is the second level, the wearable device is used for prompting the wearer to generate electrocardiographic abnormality so that the wearer can take corresponding measures.

The degree of electrocardiographic abnormality corresponding to the second level is smaller than that corresponding to the first level.

And under the condition that the electrocardio abnormality degree does not exceed the preset degree, determining that the electrocardio abnormality level of the wearer is a second level, namely a non-serious level. It should be noted that the preset degree is set by a technician.

In the application, the prompting mode can be a signal indicating lamp which prompts the wearer by related combinations of different colors, flickering frequencies and the like according to the degree of the electrocardiographic abnormality.

It should be further noted that, when the wearable device cannot be connected with the first terminal and the analysis result indicates that the electrocardiographic abnormality level of the wearer is the first level, the wearable device may also prompt the wearer to generate electrocardiographic abnormality, so that the wearer takes corresponding measures.

In some optional embodiments, the wearable device is configured to broadcast the emergency help-seeking broadcast frame with a first threshold as a time interval until the number of broadcasting times reaches a preset number of times when the wearable device cannot be connected to the first terminal and the analysis result indicates that the electrocardiographic abnormality level of the wearer is the first level.

The first threshold is preset by the wearer or technician, and may be set to 3 seconds, for example.

It can be appreciated that in places such as a large care home and a hospital, sometimes, some wearers forget to carry the paired first terminal or due to shielding of a wireless environment, etc., communication connection with the paired first terminal is abnormal, that is, many old people in the care home use wearing devices, and many wearing devices of the old people cannot establish connection with the paired first terminal.

It can be appreciated that although the bluetooth module broadcasts the emergency help-seeking broadcast frame with the first threshold as the time interval, the probability of successful transmission of the emergency help-seeking broadcast frame is improved, so that the wearer can be helped in time. However, if the emergency help broadcast frame is transmitted in an unconditional manner, flooding phenomenon is caused, so that other normal communication requirements cannot be met. In order to reduce or avoid flooding, the application stops broadcasting the emergency help-seeking broadcast frame under the condition that the broadcasting times reach the preset times. The preset times can be set according to specific conditions of the network.

In some optional embodiments, the emergency help-seeking broadcast frame includes wearer identification information, and the wearable device is further configured to broadcast the emergency help-seeking broadcast frame sent by other devices or terminals or send the emergency help-seeking broadcast frame to the first terminal, where the first terminal performs corresponding processing.

If the wearer identification information in the emergency help-seeking broadcast frame received by the wearable device is the same as the wearer identification information of the wearable device, the wearable device ignores the emergency help-seeking broadcast frame.

And under the condition that the wearer identification information in the received emergency help-seeking broadcast frame is the same as the wearer identification information of the second terminal, the second terminal ignores the emergency help-seeking broadcast frame.

In order to reduce or avoid flooding, the emergency help-seeking broadcast frame is provided with wearer identification information, and if the wearer identification information in the emergency help-seeking broadcast frame received by the wearable device is the same as the wearer identification information of the wearable device, the emergency help-seeking broadcast frame is not forwarded. The second terminal receives the emergency help-seeking broadcast frame broadcast by the wearable device, and does not broadcast the emergency help-seeking broadcast frame under the condition that the wearer identification information is the same as the wearer identification information of the second terminal. The wearable device and the second terminal store their own wearer identification information, which is an identifiable identifier of the wearer, for example, an identification card number of the wearer, etc. Alternatively, the wearer identification information may also be referred to as a wearer ID, user ID.

In some optional embodiments, if the wearer identification information in the emergency help-seeking broadcast frame received by the wearable device is different from the wearer identification information of the wearable device, the wearable device broadcasts the emergency help-seeking broadcast frame or sends the emergency help-seeking broadcast frame to the first terminal, and the first terminal performs corresponding processing.

If the second terminal is other wearable devices, the second terminal may broadcast or send the emergency help-seeking broadcast frame to the paired terminal, where the paired terminal performs corresponding processing, for example, forwarding to the target device, under the condition that the wearer identification information in the received emergency help-seeking broadcast frame is different from the wearer identification information of the second terminal.

If the second terminal is other non-wearable equipment, the second terminal forwards the first alarm information to the target equipment under the condition that the wearer identification information in the received emergency help-seeking broadcast frame is different from the wearer identification information of the second terminal.

In some optional embodiments, the emergency help broadcast frame includes a forwarding number, and if the forwarding number in the emergency help broadcast frame received by the wearable device exceeds the forwarding number threshold, the wearable device ignores the emergency help broadcast frame.

And under the condition that the forwarding times in the received emergency help broadcasting frames exceeds a forwarding times threshold value, the second terminal ignores the emergency help broadcasting frames.

In order to reduce or avoid flooding phenomenon, a forwarding frequency field is set in the emergency help-seeking broadcast frame, and if the emergency help-seeking broadcast frame is forwarded once, the forwarding frequency field is +1, when the wearable device or the second terminal receives the emergency help-seeking broadcast frame, the forwarding frequency in the emergency help-seeking broadcast frame is obtained, and after the forwarding frequency exceeds a forwarding frequency threshold value, the wearable device or the second terminal ignores the emergency help-seeking broadcast frame and does not forward any more.

In the application, the forwarding frequency threshold can be set in a self-defined way, and the forwarding frequency threshold can be set to be a value between 0 and 255, such as 20 and 30.

In some optional embodiments, if the number of times of forwarding in the emergency help-seeking broadcast frame received by the wearable device does not exceed the threshold number of times of forwarding, the wearable device broadcasts the emergency help-seeking broadcast frame or sends the emergency help-seeking broadcast frame to the first terminal, and the first terminal performs corresponding processing.

If the second terminal is other wearable equipment, and the forwarding times in the received emergency help-seeking broadcast frame do not exceed the forwarding times threshold, the second terminal broadcasts or transmits the emergency help-seeking broadcast frame to the paired terminal, and the paired terminal carries out corresponding processing.

If the second terminal is other non-wearable equipment, the second terminal forwards the first alarm information to the target equipment under the condition that the forwarding times in the received emergency help-seeking broadcast frame do not exceed the forwarding times threshold value.

Fig. 4 is a flowchart of a method for a wearable device or a second terminal to forward an emergency help broadcast frame according to an embodiment of the present invention. As shown in fig. 4, the method comprises the following steps:

the first step, receiving an emergency help-seeking broadcast frame, and judging whether the wearer identification information in the emergency help-seeking broadcast frame received by the wearable device or the second terminal is the same as the wearer identification information of the wearable device or the second terminal.

And if the wearer identification information in the emergency help-seeking broadcast frame received by the wearable device or the second terminal is the same as the wearer identification information of the wearable device or the second terminal, the emergency help-seeking broadcast frame is ignored and is not forwarded.

And thirdly, if the wearer identification information in the emergency help-seeking broadcast frame received by the wearable device or the second terminal is different from the wearer identification information of the wearable device or the second terminal, judging whether the sending device of the emergency help-seeking broadcast frame cannot be connected with the paired terminal.

And step four, if the sending equipment of the emergency help-seeking broadcast frame cannot be connected with the paired terminal, judging whether the forwarding frequency of the emergency help-seeking broadcast frame is smaller than or equal to a forwarding frequency threshold value.

And fifthly, if the sending equipment of the emergency help-seeking broadcast frame can be connected with the paired terminal, the emergency help-seeking broadcast frame is ignored and is not forwarded.

And step six, if the forwarding frequency of the emergency help-seeking broadcast frame is smaller than or equal to a forwarding frequency threshold value, judging whether the emergency help-seeking broadcast frame is successfully forwarded.

And seventhly, if the forwarding times of the emergency help broadcasting frame are larger than the forwarding times threshold, ignoring the emergency help broadcasting frame and not forwarding.

And eighth, if the emergency help broadcasting frame is not successfully forwarded, forwarding the emergency help broadcasting frame.

Wherein the forwarding number field is automatically incremented by 1.

And ninth, if the emergency help broadcasting frame is successfully forwarded, ignoring the emergency help broadcasting frame and not forwarding.

It should be noted that the emergency help broadcast frame has been successfully forwarded to the wearer with corresponding assistance.

According to an embodiment of the present invention, there is provided an electrocardiographic monitoring system, including:

The wearable device comprises a wearable device, a first terminal and a second terminal, wherein the first terminal is a pairing terminal of the wearable device.

Wherein, wearing equipment can be the electrocardio subsides. Fig. 5 is a schematic structural diagram of a wearable device according to an embodiment of the present invention, as shown in fig. 5, the wearable device includes:

An electrocardiographic sensor 501, a respiration sensor 502, and a motion gesture recognition sensor 503, wherein,

An electrocardiograph 501 for acquiring electrocardiographic data of a wearer in real time.

A respiration sensor 502 for collecting in real time the respiration status data of the wearer.

A motion gesture recognition sensor 503 for collecting motion gesture data of the wearer in real time.

The motion gesture recognition sensor may be an acceleration sensor, a gyroscope sensor or both. If the method is only used for distinguishing a few motion postures such as motion, static, falling and the like, the acceleration sensor is used, if more motion postures need to be distinguished, for example, different motion types, postures of a wearer and the like, the acceleration sensor and the gyroscope sensor are required to collect data at the same time to determine motion posture data.

The respiration sensor can acquire the respiration state data of the wearer by detecting the change in the resistance of the loop between the two electrodes.

It should be noted that the wearable device may further include other biosensors for collecting blood oxygen data, blood glucose data, etc. of the wearer. The wearable device may further comprise a temperature sensor for acquiring temperature information of the wearer in real time.

Under the condition that the wearing equipment cannot be connected with the first terminal, the wearing equipment is used for analyzing the electrocardio data, the breathing state data and the movement posture data of the wearer to obtain an analysis result, and the analysis result is used for representing the electrocardio abnormal level.

Under the condition that the wearable device cannot be connected with the first terminal and the analysis result shows that the electrocardiographic abnormality level of the wearer is the first level, broadcasting an emergency help-seeking broadcast frame, wherein the emergency help-seeking broadcast frame carries first alarm information, and the first alarm information comprises the information of the wearer and the electrocardiographic abnormality level of the wearer.

The second terminal identifies the received broadcast frame, and under the condition that the received broadcast frame is identified as the emergency help-seeking broadcast frame, the second terminal acquires first alarm information in the emergency help-seeking broadcast frame and carries out corresponding processing based on the first alarm information.

As shown in fig. 5, the wearable device further includes a main processing module 504, configured to analyze the electrocardiographic data, the respiratory status data, and the movement posture data of the wearer, so as to obtain an electrocardiographic abnormality degree of the wearer. The main processing module is connected with each sensor through an interface, wherein the interface can be an SPI interface, an I2C interface, a GPIOs interface and the like.

It should be noted that, although the electrocardiographic patch needs to monitor various data in real time, the "real-time" is also flexible, for example, if the monitoring of working for 3 seconds and resting for 1 second can meet the requirement, the real-time requirement is considered to be met, so the electrocardiographic patch will generally have a working mode and a resting mode. Preferably, when an emergency needs to send an emergency help broadcast frame, whether a matched terminal is connected is judged, if the matched terminal is connected, the time for modifying the working mode is not needed, and if the matched terminal is not connected, the time for the electrocardio paste working mode can be increased in order to increase the probability of forwarding the emergency help broadcast frame.

Table 1 shows the format of the emergency help broadcast frame.
