The invention also provides a calibration method of the electrocardio diagnosis and analysis system, which comprises the following steps:
before delivery or after maintenance, the calibration module provides a calibration basis for generating high-precision weak analog signals by detecting necessary analog signals, and meets the precision requirement.
S1, firstly, providing a power supply and a reference voltage required by the whole verification process by the power supply module and the power supply management module, then starting up, inputting instruction signals by a user through the man-machine communication module, and setting configuration parameters of the verification device of the electrocardio diagnosis analysis system and the intelligent terminal equipment; the selection is then entered by manual input into either an automatic certification mode or a manual certification mode, which is specifically set for certification device (system) traceability or some other need.
S2, sending a control signal after a first controller in the central processing module or a second controller in the intelligent terminal device receives an instruction signal of a user, and transmitting the control signal to the electrocardio diagnosis and analysis system through the communication module, wherein the electrocardio diagnosis and analysis system makes corresponding adjustment settings on filtering, sensitivity, speed and the like after receiving the control signal;

The intelligent terminal device transmits a ready signal to the central processing module through the communication module;

In the existing verification, a fixed waveform is output to an electrocardiogram diagnosis and analysis system, and then whether the result is qualified or not is judged according to manual measurement and analysis of a printed electrocardiogram; one of the automatic verification mentioned in the application is automatic verification through a communication module, but the process is very easy to enable the cheating idea of a bad manufacturer to be possible without interference;
therefore, the problem can be solved by randomly changing some parameters of the waveform in amplitude and time within a certain range, for example, according to the existing verification rule JJG1041-2008, the judgment of the internal calibration voltage error term is realized by outputting a square wave of 2.5Hz and 1mV to an electrocardiograph, while in the application, the fixed 2.5Hz and 1mV can be changed into (2-3) Hz and (0.9-1.1) mV, and other verification terms can be adjusted similarly. Therefore, cheating behaviors of bad manufacturers, which are carried out by simply outputting corresponding values of 1.0mV or (0.95-1.05) mV internal voltage, can be killed in the idea; the method for preventing cheating is further enhanced, namely the waveform information data sent back by the electrocardio diagnosis and analysis system is compared with the image analysis result randomly through the printed electrocardiogram, and if the result difference is out of a reasonable range, cheating can be judged.
Therefore, the parameters of the control signal sent by the central processing module are randomly changed, the returned waveform data signal and the previously reserved data are analyzed and compared through the first anti-cheating algorithm module or the second anti-cheating algorithm module, and whether the analysis and comparison result is within an allowable range is judged; or the analysis result of the image data and the analysis result of the waveform data signal are analyzed and compared through a second anti-cheating algorithm module, and whether the analysis and comparison result is within an allowable range or not is judged. (the anti-cheating algorithm of the present invention is used to explain the invention but is not limited to the above two ways.)
If the analysis result of the waveform data signal or the image data is within the allowable range, the detection item is qualified, the judgment of the next item is continued, and otherwise, the detection item is not qualified;
