Description

Electrocardiogram detection device and system Technical Field The application relates to the technical field of detection equipment, in particular to an electrocardiograph detection device and system. Background Cardiovascular and cerebrovascular diseases are common diseases seriously threatening the health of human beings, especially middle-aged and elderly people over 50 years old, and have the characteristics of high morbidity, high disability rate and high mortality rate. The electrocardio detection is used as a diagnosis and monitoring method for monitoring and evaluating cardiovascular and cerebrovascular diseases, and has important significance for diagnosing and treating the cardiovascular and cerebrovascular diseases. In daily life, the user mainly carries out electrocardiographic detection through an electrocardiographic detection device. However, the large volume of the existing electrocardiograph detection device results in poor comfort for users when using the electrocardiograph detection device. Disclosure of Invention The application provides an electrocardiograph detection device and system, which can reduce the volume of the electrocardiograph detection device. In order to achieve the above purpose, the application adopts the following technical scheme: In a first aspect, the application provides an electrocardiograph detection device, which comprises an electrode and a circuit board, wherein the electrode is provided with a detection surface, a sensing chip and an interface. The detection surface is used for inducing charges of a user, the sensing chip is used for converting the charges into voltage signals and transmitting the voltage signals to the circuit board through the interface, and the circuit board is used for generating electrocardio waveforms according to the voltage signals and supplying power to the electrodes through the interface. It can be seen that when the electrocardiograph detection device provided by the application is used for electrocardiograph detection, the electrocardiograph waveform of the user can be obtained only by sensing the charge of the user through one detection surface of the single electrode and then carrying out subsequent processing through the sensed charge. By only configuring a single electrode, the volume of the electrocardiograph detection device is reduced, and the use comfort and convenience of the electrocardiograph detection device are improved. Alternatively, the detection surface may be a dry electrode or conductive silicone with a surface tinned. Alternatively, the detection surface is circular, rectangular or arc-shaped. For example, the detection surface may be a circular shape with a diameter of 2 centimeters (cm) and a surface tinned dry electrode. In one possible implementation, the detection surface may include a first detection surface and a second detection surface. The first detection surface is used for sensing first charges of a user, and the second detection surface is used for sensing second charges of the user. It can be appreciated that, in electrocardiographic detection, the quality of electrocardiographic waveforms obtained by electrocardiographic detection can be improved by detecting the user charges through the two detection surfaces respectively. For example, human body charges induced by two detection surfaces of the electrode are converted into two voltage signals, and interference suppression is performed by the difference between the two signals, so that electrocardiographic signals can be detected at a single position of the human body, and the electrocardiographic signals are not limited to electrocardiographic detection at two positions. Optionally, at least one of the materials, areas or shapes of the first detection surface and the second detection surface are the same. For example, the first detection surface and the second detection surface are both circular electrodes with a diameter of 2cm and are surface-tin-plated. In one possible implementation, the electrode is further provided with a detection point for jointly sensing the first charge with the first detection surface or the second charge with the second detection surface. It can be appreciated that, when electrocardiographic detection is performed, the quality of electrocardiographic waveforms obtained by electrocardiographic detection can be improved by jointly detecting the user charges through the detection points and the detection surface. Alternatively, the probe points may be surface tinned dry electrodes Optionally, the detection point is circular. For example, the probe points may be circular with a diameter of 3mm and surface tinned dry electrodes. In one possible implementation manner, the first detection surface is disposed on the front surface of the electrode, the second detection surface and the sensing chip are disposed on the back surface of the electrode, the electrode is further provided with a first via hole, and the first detecti
