receiving the sensor data;

filtering noise frequencies in the sensor data;

Performing data analysis on the sensing data; wherein the data analysis may include extracting time domain features from the sensing data after removing the noise frequency; and may also include extracting frequency domain features from the sensing data after removing the noise frequency;

Whether the lead electrode is operated by the user is judged according to the data analysis results of the sensor data; wherein, a time domain threshold can be preset, the average value of the time domain data of the sensor data within a certain period of time is counted, and the average value of the time domain data is compared with the time domain threshold, and when the average value of the time domain data is greater than or equal to the time domain threshold for the first time, it is judged that the lead electrode is operated by the user. It can be understood that the average value can also be replaced by an intermediate value, a maximum value, a minimum value, a mean square error, etc., and the certain time can also be any time period; a frequency domain threshold can also be preset, the fluctuation size of the frequency domain data of the sensor data within a certain period of time is counted, and the fluctuation size of the frequency domain data is compared with the frequency domain threshold, and when the fluctuation size of the frequency domain data is greater than or equal to the frequency domain threshold for the first time. When the lead electrode is operated by the user, it is determined that the certain time period can be any time period. It is also possible not to set the time domain threshold and the frequency domain threshold, but to determine the data regularity of the time domain or frequency domain by statistical methods through machine learning, and deduce the time domain or frequency domain data range corresponding to the time when the lead electrode is operated by the user, so as to determine whether the measured time domain or frequency domain data falls into the time domain or frequency domain data range corresponding to the time when the lead electrode is operated by the user. If the measured time domain or frequency domain data falls into the time domain or frequency domain data range corresponding to the time when the lead electrode is operated by the user, it is determined that the lead electrode is operated by the user. It is understandable that the time domain and frequency domain data range corresponding to the time when the lead electrode is operated by the user is in a state of being corrected in real time and is not fixed.

S207, issuing a prompt message, wherein the prompt message includes identification information of the operated lead electrode; and

S208, closing the prompt information.

In step S201, the sensing result may be a pressure change value, a temperature change value, an acceleration change value, a voltage change value, a light reflection amount change value, an electromagnetic change value, etc.

In step S205, a time domain threshold may be preset, and the average value of the time domain data of the sensing data within a certain period of time may be counted, and the average value of the time domain data may be compared with the time domain threshold. When the average value of the time domain data is greater than or equal to the time domain threshold for the first time, it is determined that the lead electrode is operated by the user. It can be understood that the average value may also be replaced by a maximum value, a minimum value, a mean square error, etc., and the certain period of time may also be any time period. A frequency domain threshold may also be preset, and the fluctuation size of the frequency domain data of the sensing data within a certain period of time may be counted, and the fluctuation size of the frequency domain data may be compared with the frequency domain threshold. When the fluctuation size of the frequency domain data is greater than or equal to the certain period of time for the first time, the frequency domain threshold may be preset. When the frequency domain threshold is reached, it is determined that the lead electrode is operated by the user. It can be understood that the certain time can also be any time period. It is also possible not to set the time domain threshold and the frequency domain threshold, but to use machine learning to use statistical methods to determine the data regularity of the time domain or frequency domain, and derive the time domain or frequency domain data range corresponding to the lead electrode being operated by the user, so as to determine whether the lead electrode is operated by the user by judging whether the measured time domain or frequency domain data falls into the time domain or frequency domain data range corresponding to the lead electrode being operated by the user. It can be understood that the time domain and frequency domain data range corresponding to the lead electrode being operated by the user are in a real-time modified state and are not fixed.

In step S206, the identification information of the operated lead electrode may include electrode information, such as RA, RL, etc., and may also include installation position guidance information of the lead electrode, for example, it should be installed in the first intercostal space of the mid-clavicular line at the right edge of the sternum, etc.

Among them, the identification information of the operated lead electrode can be obtained by analyzing the sensing data. For example, the data source of the sensing data can be analyzed, and the identification information of the operated lead electrode can be obtained by referring to the correspondence between the data source of the sensing data and the lead electrode; the transmission port of the sensing data can also be obtained, and the identification information of the operated lead electrode can be obtained by referring to the correspondence between the transmission port and the lead electrode.

In step S207, the prompt information includes identification information of the operated lead electrode, and the prompt information can be sent in the form of sound, in the form of image, or in the form of sound plus image; wherein the image can include an identification image of the lead electrode, and can also include a guide map for the placement of the lead electrode.

In step S207, the prompt information can be controlled to be closed by judging whether the lead electrode has been successfully placed; if it has been installed at an appropriate position on the user's body, the prompt information is closed, wherein the information on whether the lead electrode has been successfully placed can be provided by a connected medical monitoring device, can be judged and provided manually, or can be obtained through other means; the prompt information can also be controlled to be closed by judging whether the lead electrode is still being operated by the user; if the lead electrode is no longer being operated by the user, the prompt information is closed.

Among them, the method for judging whether the lead electrode is still operated by the user can be: counting the average value of the time domain data of the sensing data within a certain period of time, and comparing the average value of the time domain data with the threshold value, when the average value of the time domain data is lower than the threshold value for the first time, judging that the lead electrode is still operated by the user, and when the average value of the time domain data is lower than the threshold value for the second time, judging that the lead electrode is no longer operated by the user; the average value of the time domain data of the sensing data here can also be the median value, maximum value, minimum value, mean square error, etc. of the time domain data of the sensing data.

Preferably, after determining that the lead electrode is no longer operated by the user, the prompt information is closed after a certain delay.

Compared with traditional lead electrode identification devices and methods, the lead electrode identification device and method of the embodiment of the present technical solution senses the user's operation and determines whether the lead electrode is operated by the user. If it is operated by the user, the identification information of the conductive electrode is obtained and prompt information is issued, so that the user can quickly and accurately identify the lead electrode.
