Each register unit is used for receiving and storing an electrocardiographic acquisition signal, and when receiving a configuration signal, outputs the stored electrocardiographic acquisition signal to a corresponding signal input interface of the communication control module 103 according to the configuration signal.

When the initialization unit of the electrocardiogram acquisition module outputs a path of electrocardiogram acquisition signal, the corresponding register unit can store the corresponding electrocardiogram acquisition signal so as to output the electrocardiogram acquisition signal, and when the communication control module 103 outputs the configuration signal to the register unit, the register unit and the corresponding signal input interface of the communication control module 103 successfully establish a safe signal transmission channel; the register unit starts a signal transmission process, and outputs the stored electrocardio acquisition signal to the communication control module 103 so as to ensure the electrocardio information transmission precision and transmission efficiency, and the communication control module 103 can access multiple channels of electrocardio acquisition information to realize a complete information integration function. Therefore, the communication control module 103 in this embodiment can wake up the signal transmission state of the register unit through the configuration signal, which not only avoids transmission errors of the electrocardiographic data and loss in the transmission process, but also ensures the electrocardiographic data transmission precision and processing precision of the multi-path electrocardiographic acquisition circuit 10, so that the health state of the human body can be obtained more accurately according to the electrocardiographic detection result output by the communication control module 103.

As an optional implementation manner, the communication control module further includes M communication control interfaces, the M communication control interfaces are respectively connected with the M electrocardiograph acquisition modules in a one-to-one correspondence manner, the communication control module outputs the initialization signal and the configuration signal to the initialization unit and the register unit in the corresponding electrocardiograph acquisition module through the communication control interfaces, and further performs initialization operation and signal transmission state configuration operation on the corresponding electrocardiograph acquisition module through the communication control interfaces, when the register unit is successfully connected with the corresponding signal input interface in the communication control module 103, the stored electrocardiograph acquisition signal is output to the corresponding signal input interface in the communication control module 103 through the register unit, so as to implement the functions of fast processing and efficiently forwarding electrocardiograph information, the communication control module 103 can completely access multiple electrocardiograph acquisition signals and implement the function of information integration, the inside of the multi-channel electrocardio acquisition circuit 10 has higher communication compatibility.

The M data cache units are respectively connected with the M signal input interfaces in a one-to-one correspondence mode, and each data cache unit is used for accessing corresponding electrocardio acquisition signals and storing the electrocardio acquisition signals.
