As shown in fig. 1, an electrocardiograph recorder 10 according to a first embodiment of the present application includes a controller 11 and an acceleration sensor 12, where the acceleration sensor 12 is connected to the controller 11.

The acceleration sensor 12 is used for acquiring speed change data generated by the electrocardiograph 10 and transmitting the acquired speed change data to the controller 11; the controller 11 is configured to generate a first record of the occurrence time of the user double-click event according to the speed change data collected by the acceleration sensor 12.

Specifically, the basic hardware structure of the electrocardiograph recorder 10 can refer to the structure of an existing electrocardiograph recorder, and may include a power module, an LED display screen, an electrocardiograph sensor, and the like, for monitoring the electrocardiographic condition of a user. The electrocardiograph 10 in the present application further includes a controller 11 and an acceleration sensor 12 on the basis of the existing electrocardiograph, and the controller 11 and the acceleration sensor 12 are electrically connected to each other. The controller 11 may be an MCU chip, or a time-delay power-on circuit built by using discrete components, such as a 555 timer, an MOS transistor, a capacitor, and the like. The acceleration sensor 12 may be implemented by a sensor capable of collecting speed variation data, such as a capacitive acceleration sensor, an inductive acceleration sensor, a strain-type acceleration sensor, a piezoresistive acceleration sensor, and the like. As one embodiment, the acceleration sensor 12 is a MEMS (micro electro Mechanical Systems) sensor, and the MEMS sensor is a piezoresistive sensor, and has the characteristics of small volume, light weight, low cost, low power consumption, high reliability, suitability for batch production, easiness in integration, and intelligence. In addition, the controller 11 in the present application can integrate a processing mechanism for the acceleration sensor 12 on the controller of the existing electrocardiograph, and the acceleration sensor 12 is connected with the controller 11, so that the controller 11 can process the speed change data acquired by the acceleration sensor 12. The controller 11 may also be independently disposed in the electrocardiograph 10, and is specifically connected to the acceleration sensor 12 for processing the speed change data collected by the acceleration sensor 12.

The electrocardiograph 10 provided in this embodiment can be slapped when the user feels uncomfortable, the electrocardiograph 10 generates speed change data, the acceleration sensor 12 acquires the speed change data generated by the electrocardiograph 10, and the controller 11 acquires a first record of the occurrence time of the double-click event of the user according to the speed change data acquired by the acceleration sensor 12. Therefore, double-click event records can be conveniently formed, and perception data of the user can be obtained. Furthermore, more accurate diagnosis and judgment can be made by combining the sensing data formed by the first record of the occurrence time of the double-click event of the user with the electrocardiogram data of the user.

It should be noted that the speed change data generated by the electrocardiograph 10 at any time can be collected by the acceleration sensor 12, including the user running, jumping or double-clicking. Compared with the exercise of running, jumping and the like, the speed change generated by the electrocardiograph 10 due to the double-click event of the user is very fast, and the speed change disappears very fast, so the controller 11 can process the speed change data generated by the electrocardiograph 10 according to the characteristics of the double-click event of the user, and acquire the first record of the occurrence time of the double-click event of the user. The controller 11 in the present application integrates the existing processing algorithm for the speed change data collected by the acceleration sensor 12, and can accurately generate the first record of the occurrence time of the double-click event of the user.

In one embodiment, the abscissa of the velocity change data collected by the acceleration sensor 12 is time, and the ordinate is the magnitude of the velocity change generated by the electrocardiograph 10. In order to make the data collected by the acceleration sensor 12 more comprehensive, the acceleration sensor 12 collects the speed change data generated by the electrocardiograph 10 in the X axis, the Y axis and the Z axis respectively. After the controller 11 acquires the speed change data acquired by the acceleration sensor 12, the original speed change data is normalized, including resampling the speed change data and scaling the speed change data, so as to unify the range and precision of the speed change data; and then respectively calculating differential data of speed change data of each axis of an X axis, a Y axis and a Z axis, wherein the differential data is the difference value between the speed change data of the current moment and the speed change data of the previous moment, the differential data reflects the change condition of the speed change data, peaks generated by clicking operation are continuously searched in a first preset number of continuous differential data, and if a peak generated by clicking operation to be selected is stored in a register module of the algorithm before the peak, whether the interval time of the two peaks is within a preset time threshold range is judged. If the current time is within the preset time threshold range, the controller 11 judges that the user double-click event occurs currently, records the occurrence time of the current user double-click event, and removes the peak generated by the current click operation to be selected from a register module of the algorithm. And if the peak generated by the click operation to be selected does not exist in the register module of the algorithm, the newly detected peak generated by the click operation is taken as the peak generated by the click operation to be selected and stored in the register module of the algorithm.

Judging whether the differential data at the current moment is the peak of the clicking operation and needs to meet the following four requirements, namely firstly, the size of the differential data at the current moment needs to exceed a set first threshold; secondly, the slope of the differential data at the current moment needs to be changed; thirdly, the difference data of a second subsequent preset number at the current moment exceeds a set second threshold; fourthly, the value distribution of the differential data at the current moment and the value distribution of the differential data with the third preset number before and after are concentrated. In addition, under the condition that the data at the current time meet the requirements of the four points, if the proportion that the difference data of the fourth preset number before and after the current time and the difference data at the current time are close to each other exceeds a third set threshold, it is indicated that the interference of the difference data at the current time is large, and the reliability of the current peak is low, namely the peak generated by the clicking operation, the difference data at the current time is abandoned as the peak generated by the clicking operation. The controller 11 can accurately generate the first record of the occurrence time of the double-click event of the user by processing the speed change data collected by the acceleration sensor 12.

In the prior art, when a user feels uncomfortable, the user records a user event by pressing a recording button on an electrocardiogram recorder. However, when the user feels uncomfortable, the user is not convenient to operate if the user needs to find the corresponding recording button. According to the method and the device, when the user feels uncomfortable, the electrocardiograph recorder 10 is double-clicked, the acceleration sensor 12 is used for collecting speed change data generated by the electrocardiograph recorder 10, the controller 11 is used for obtaining the recording result of the double-click event occurrence time of the user according to the speed change data collected by the acceleration sensor 12, and convenience in operation of recording the user event is effectively improved.

Specifically, the data transmission module 13 may be any one of a 3G module, a 4G module, a 5G module, a bluetooth module, and a wifi module.

The terminal device may be a mobile phone or a computer, and the data transmission module 13 may be connected to the terminal device wirelessly. The terminal equipment integrates the existing processing algorithm of the speed change data, and the processing algorithm is consistent with the processing algorithm of the speed change data, so that the speed change data can be processed, double-click events can be identified, and a second record of the occurrence time of the double-click events of the user can be generated. When the controller 11 of the electrocardiograph recording device 20 has more processing threads and is not ready to process the speed change data collected by the acceleration sensor 12, the speed change data obtained by the controller 11 can be transmitted to the terminal device through the data transmission module 13, so that the terminal device generates a second record of the occurrence time of the user double-click event according to the speed change data.

As one embodiment, the data transmission module 13 is further configured to transmit the first record obtained by the controller 11 to the terminal device, so that the terminal device combines the first record and the second record to generate a third record of the occurrence time of the user double-click event.

Specifically, since the data processing environments of the controller 11 and the terminal device are different, the first record and the second record of the occurrence time of the user double-click event may be different, and in order to ensure that the record of the occurrence time of the user double-click event is more complete, the data transmission module 13 is further configured to transmit the first record obtained by the controller 11 to the terminal device, and the terminal device combines the first record and the second record to generate a third record of the occurrence time of the user double-click event. For example, the terminal device may simply sum the first record and the second record to generate a third record of the time of the user double-click event.

The speed change data and/or the first record obtained by the controller 11 are/is stored in the storage module 14, and the data of the current user can be stored for a long time. When needed, the data can be exported through other data export interfaces such as USB and the like so as to be used by users.

Specifically, the alarm module 15 may be an alarm lamp or a buzzer installed at a user end of the electrocardiograph 40 or at a control end of the electrocardiograph 40, or may be a combination of the alarm lamp and the buzzer. When the controller 11 detects that the double-click event occurs, which indicates that the user feels uncomfortable, the alarm module 15 sends an alarm prompt message to the outside, so that the user's condition can be found in time.

As shown in fig. 5, in the electrocardiograph 50 provided in the fifth embodiment, on the basis of the electrocardiograph 10 provided in the first embodiment, the electrocardiograph 50 further includes a temperature sensor 16 and a respiration sensor 17, and the temperature sensor 16 and the respiration sensor 17 are respectively connected to the controller 11.

Specifically, because the electrocardio conditions of the user in different states are different, for example, the electrocardio conditions of the user in sleep, exercise and other states are different, obtaining the current state of the user is also important for monitoring the electrocardio conditions of the user.
