Driver electrocardiogram monitoring system and method on basis of Android cellphone and 3D electrodes

Abstract

Disclosed is a driver electrocardiogram monitoring system and method on the basis of an Android cellphone and 3D electrodes. The driver electrocardiogram monitoring system comprises conduction electrodes, an electrocardiogram acquiring circuit, a lower computer module, a Bluetooth module and the Android cellphone. The conduction electrodes include two conductive fabric electrodes and three electrodes, the conductive fabric electrodes are arranged on contact positions of a steering wheel and hands of a driver, two of the electrodes are arranged at the positions of a driver seat corresponding to the back of the driver, and the rest electrode is arranged at the position of the driver seat corresponding to a right leg of the driver. The electrocardiogram acquiring circuit comprises a pre-amplification circuit and a power frequency wave trap circuit, the lower computer module is connected with the power frequency wave trap circuit, and the lower computer module is connected with the Bluetooth module. The Android cellphone is wirelessly connected with the lower computer module through the Bluetooth module. The 3D electrodes are used as reference electrodes, interference resistance is improved, the 3D electrodes can be well fitted to the body surface of an examinee without extra support, the Android cellphone can be provided with GPRS (general packet radio service), GPS (global positioning system) and alarm functions of itself, and portability and reliability of the system are greatly improved.

Description

technical field [0001] The invention relates to the interdisciplinary fields of biomedical engineering and mechatronic engineering technology, in particular to a driver's ECG monitoring system and method based on an Android mobile phone and 3D electrodes. Background technique [0002] In recent years, with the rapid increase in the number of cars, road traffic safety issues have become increasingly serious, and the health of drivers has also attracted people's attention. The proportion of drivers suffering from cardiovascular disease due to poor traffic environment and lack of rest is also increasing year by year. According to domestic news survey statistics, about 10% of drivers suffer from cardiovascular disease. In the current harsh traffic environment, sudden heart disease or fatigue driving are prone to accidents. The detection of the driver's ECG signal is directly related to the safety of the driver's life. Therefore, it is particularly important to accurately and q...

Problems solved by technology

[0003] At present, most of the commonly used ECG measurement systems use wet electrodes, that is, conductive paste needs to be applied when measuring ECG signals. This method has the following defects: the conductive paste will irritate the human skin, causing the subjects to have different degrees of allergic reactions ; and after a period of time, the moisture in the conductive paste will evaporate, resulting in an increase in impedance and increased signal acquisition noise; for long-term monitoring, it is necessary to apply conductive paste multiple times in order to reduce impedance, which will bring great inconvenience; The operation of the driver will be affected during the process, so it is not suitable for the driver to use

There are also some driver safety monitoring devices, such as remote early warning systems for fatigue driving, and anti-sleep wake-up devices for car drivers. These solutions solve some problems about fatigue driving, but they do not mention the sudden illness of drivers; For example, patent document 201220268385.6 discloses "a vehicle driver's health status monitoring system", which uses several electrodes installed on the vehicle, an analog-to-digital conversion unit, a central control unit, an alarm unit and a data storage unit, a GPRS wireless communication unit, a GPS global Although it solves the prediction and alarm of the driver's sudden heart disease, it uses more modules and the cost is higher. In addition, the portability and reliability of the equipment need to be further improved.
