Wearable intelligent ECG monitoring system is the following:
1. Hardware structure and principle of wearable ECG monitoring system
Using ECG electrodes to extract weak ECG signals from the human body, filtering out interfering signals and then amplifying them, the analog signals obtained are processed by conditioning circuits, and then wirelessly transmitted to the 485 bus through RFID, and the data are sent from the 485 bus to the PC and stored in the network database. As shown in the figure:
RFID through the radio frequency signal automatic diagnosis and obtains the related data, the data recognition speed is fast, the capacity is big, can recognize at the same time the multi-objective as well as the movement target and the operation is convenient and quick. the RFID system includes the electronic label, reads and (or) writes the card, the data processing software platform and so on the 3 big parts. the RFID electronic label storage capacity can reach the megabyte, also can repeat the read-write, may Access to equipment information at any time.
In order to grasp the use of wearable ECG monitoring system in real time, in its fixed paste active RFID tags; in a certain range of free patient activities in the regional distribution of the installation of RFID readers, the wider the scope of its installation, the patients can be free to activities in the area of the greater the readers of the electronic coding can be corresponded to the corresponding patient's activities in the region of the identity (Identity, ID) identification. With active RFID wearable ECG monitoring device as long as the distribution of RFID readers installed in a certain range of areas, can be recognized by the RFID reader in the region, RFID corresponding to the wearable ECG monitoring device information as well as the collected ECG data through the 485 bus transmission to the upper PC, the upper PC based on the information obtained will be RFID code and the corresponding patient ID. Based on the information obtained, the upper PC corresponds the RFID code to the corresponding ECG monitoring device, i.e. the corresponding patient ID, and then automatically tracks and monitors the operation of the ECG monitoring device, and stores the data in the network database in the background; if necessary, it can also display the captured ECG on the screen of the upper PC in real time. Doctors or patients can also access the network database through the Internet and extract the corresponding ECG data according to the patient ID, and then apply the supporting system software to monitor the corresponding ECG at any time.
2. Software design of wearable ECG monitoring system
The system software reads the collected ECG data, dynamically displays the ECG signals on the computer in real time, and applies the wavelet analysis toolbox of MATLAB to perform simple parameter detection and waveform detection on the real-time collected ECG signals. The system adopts the standard Windows window interface style, which mainly consists of functional modules such as system setting, ECG acquisition, ECG analysis and help. After entering the system, you can query, modify, save and print the basic information of the monitored patients at any time.
