Objective To design a multi-parameter electrocardiograph monitor based on CAN network. Methods Applied with CAN network, ECG (electrocardio), SPO2, NBP (non-invasive blood pressure) and other vital signs parameters are dynamically detected, the ECG algorithm is also improved by wavelet, so as to improve the accuracy of ECG. Results This method could effectively identify the location of wave R from the noise interference, and has high accuracy rate of 99.83%. Conclusion This device could get work with simple structure, high integration, which also achieves a real-time monitoring in unattended conditions.
