Example Embodiment

[0043] Example 1

[0044] The invention is particularly suitable for users suffering from acute diseases and elderly users. As we all know, patients with acute diseases such as stroke patients will basically lose speech function first and then lose movement function. At this time, patients can no longer save themselves through terminals such as 120. If the patient is able to consciously tap the mattress, Sending out a self-help signal undoubtedly provided a lot of time for one's own rescue. However, since the external load received by the mattress is too much, and in this case, even if the patient sends a knock signal to the mattress body, it may not be recognized by the system and cause self-rescue failure. Therefore, the present invention provides an early warning system based on knock signals, which is especially suitable for people with cerebral infarction / myocardial infarction.

[0048] Example 2

[0049] This embodiment discloses an early warning system based on a tapping signal. In the case of no conflict or contradiction, the whole and / or part of the content of the preferred implementation of other embodiments can be used as a supplement to this embodiment. Preferably, the system can be implemented by the method of the present invention and / or other alternative modules.

[0050] Preferably, the processing unit 3 can also use the STA / LTA algorithm to identify the percussion signal to obtain the pulse frequency and time interval of the percussion signal. Wherein, when the ratio of the average value STA in the long time window to the average value LTA in the short time window is greater than the preset ratio threshold, the processing unit 3 activates the early warning unit 4 at least once. And / or the processing unit 3 records a tap pulse and the time of recording the tap pulse to confirm the pulse frequency and time interval of the tap signal, which are st...

Abstract

The invention relates to a warning system based on a knocking signal. The system comprises a mattress body, a sensing unit, a processing unit, a warning unit, a decision making unit and a monitor unit, wherein the sensing unit is in response to the external excitation received by the mattress body and is used for collecting power information of the mattress body; the processing unit is used for reading the screening condition in a sample database based on the power information collected by the sensing unit, and marking the power information into a knocking signal to obtain at least one characteristic value of the knocking signal under the situation that the sample data accords with the screening condition of the preset sample database; the decision making module is in response to successful matching of the characteristic value and the corresponding trigger condition thereof and is used for determining a monitor scheme based on the matching relationship between the characteristic valueand the corresponding trigger condition thereof and starting the monitor unit based on the monitor scheme; and the processing unit is used for generating warning information and transmitting the warning information to the warning unit under the situation that physiological data information and/or environmental data information is abnormal based on the physiological data information and/or environmental data information collected by the monitor unit.

Description

technical field [0001] The invention belongs to the technical field of smart home and relates to an early warning system based on knocking signals. Background technique [0002] With the continuous improvement of people's material level, more and more people begin to pay attention to their own quality of life. Young people are under multiple pressures from the combination of work pressure, pension pressure and child-rearing pressure. Nowadays, there are many elderly people living alone and empty nesters in the society. Therefore, many phenomena such as sudden death due to work and emergencies where the elderly live alone cannot be rescued in time have occurred in the society. These emergencies have caused society to pay close attention to how to effectively rescue groups living alone in emergencies. With the development of smart technology, more and more smart homes or smart systems can be used to monitor the physiological state of users, but none of them can solve the tec...
