Bluetooth module in the said adapter; Should be able to realize that 10m is with interior audio transmission task; Can send transmission requests to intelligent terminal's bluetooth receiver module; After the built-in bluetooth equipment of intelligent terminal's bluetooth equipment and adapter was found the other side each other, it was the specified password of adapter that the user is asked in intelligent terminal's bluetooth equipment, import manufacturer.Behind the input password, the connection that breaks the wall of mistrust will verified and accomplish to equipment each other.
Main controller module MCU in the said adapter is one-chip computer module or other intelligent processing module (like DSP, FPGA, ARM etc.).
Mould/number conversion module (A/D modular converter) in the said adapter mainly will be simulated cardiechema signals and convert digital cardiechema signals into.
Power module in the said adapter can be realized with lithium battery, mainly is used for each module for power supply into adapter.
The whole system of hear sounds diagnosis comprises: the intelligent terminal of heart sound transducer, adapter, band bluetooth receiver module, and wherein adapter is connected with heart sound transducer, and the other end of adapter is connected with the intelligent terminal through bluetooth.
Said heart sound transducer can be gathered heartbeat and other body surface arteriopalmus signals, handles through the Highgrade integration signal processing circuit again, and output Low ESR audio signal can be carried out the collection recording of cardiechema signals and handled.
Said intelligent terminal should have the bluetooth receiver module, input modules such as display module, touch screen or button.
The operation principle of this utility model is following:
The user gathers the human body hear sounds with heart sound transducer, and the hear sounds that collects is handled through adapter, sends to the intelligent terminal with bluetooth receiving equipment through the bluetooth transmitting apparatus of adapter.
Wherein, the signal condition module of adapter is amplified the cardiechema signals that collects and Filtering Processing, makes the signal of handling be fit to carry out the A/D conversion.
The mould of adapter/number conversion module (A/D modular converter) will be simulated cardiechema signals and converted digital cardiechema signals into.
The bluetooth transmitting apparatus of adapter after digital cardiechema signals is decoded sends digital cardiechema signals.
Then, cardiechema signals is sent to intelligent terminal's bluetooth receiving equipment through after the processing of bluetooth module by wireless module.
Intelligent terminal's radio receiver connects with the bluetooth transmitting apparatus behind the password of input bluetooth transmitting apparatus.
Behind wireless receiving module, intelligent terminal's bluetooth equipment carries out filtering to cardiechema signals, and voltage stabilizing is handled cardiechema signals through little process chip then.Then, intelligent terminal's module adopts software that the cardiechema signals that receives is shown in real time, the time-frequency conversion, and feature extraction, the hear sounds analysis result is exported in pattern recognition at last.
This utility model and prior art compare, and its characteristics and beneficial effect have:
1 carries out amplification filtering through adapter to cardiechema signals handles, and has avoided being transferred to PC and has handled the noise that is produced again;
