Problems solved by technology
[0002] ECG (electrocardiogram) is an electronic record of heart activity for the diagnosis of cardiovascular diseases. Most current ECG devices do not process the collected ECG waveforms. Experienced physicians measure and analyze the parameters of the ECG and conduct Diagnosis, the directly collected ECG waveform analysis is very inconvenient, and it is even more troublesome for some inexperienced physicians to deal with
Some electrocardiogram machines simply extract and analyze some data, but they are all simple waveform parameters and the standards adopted by different manufacturers of electrocardiogram (ECG) machines are not the same, and the collected ECG data cannot be used by different owners. ECG diagnostic device transmission, that is, cannot appear in a ubiquitous manner on computer platforms without proprietary software installed
This brings great obstacles to the sharing of ECG data

Embodiment 1
[0024] The present invention consists of two parts, a host computer and a lower computer. The lower computer completes the collection of ECG data and the extraction of attributes, and the analog ECG signals collected by ECG electrodes pass through lead wires and signal processing circuits (protection circuits, drive amplifiers, Signal buffer) Send the analog signal to ADuC7024, and ADuC7024 completes the conversion from analog signal to digital signal and completes the extraction of ECG attributes, and then transmits the digital signal to the host computer through the serial port level conversion circuit and RS232 serial port line; the host computer is mainly composed of The system host, LCD display, keyboard, mouse and other parts are composed of several parts, among which the system host equipped with a standard "ontology" mainly completes ECG data standardization, data storage, network transmission and other functions. The standardized ECG is in the form of knowledge display...

The invention relates to an ECG knowledge expression based on an ontology and the construction of a knowledge base, wherein the ECG knowledge expression based on the ontology specifically comprises the following steps: 1 performing an abstract definition according to each attribute of an ECG and constructing a standard ontology frame; 2 converting ECG data into a knowledge expression using a Protege ontology editor and the constructed ontology frame, that is, completing the addition of an ontology example, and storing the constructed ontology example as an OWL document; and 3 analyzing the constructed ontology example using the API interface provided by Jean 2, and completing the connection with a MySQL database by using JDBC, then an ECG semantics expression based on the ontology is stored in the database in the form of knowledge. The invention has the advantages of assisting a doctor in diagnosis and raising the vigilance of a common user in cardiovascular diseases.

【Technical field】 [0001] The present invention relates to the technical field of ontology, specifically, an expression of ECG knowledge based on "ontology" and construction of a knowledge base. 【Background technique】 [0002] ECG (electrocardiogram) is an electronic record of heart activity for the diagnosis of cardiovascular diseases. Most current ECG devices do not process the collected ECG waveforms. Experienced physicians measure and analyze the parameters of the ECG and conduct For diagnosis, it is very inconvenient to analyze the directly collected ECG waveform, and it is even more troublesome for some inexperienced physicians to deal with. Some electrocardiogram machines simply extract and analyze some data, but they are all simple waveform parameters and the standards adopted by different manufacturers of electrocardiogram (ECG) machines are not the same, and the collected ECG data cannot be used by different owners. Transmission in ECG diagnostic devices, that is, ...
