Description of drawings
Fig. 1 is a structured flowchart of the present utility model;
Fig. 2 is an electrical schematic diagram of the present utility model;
Fig. 3 is the schematic diagram of this utility model pulse-tracing collection treatment circuit.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, this utility model comprises fpga chip, communication interface, data storage, the FLASH memorizer, display and pulse-tracing collection treatment circuit, communication interface, FLASH memorizer, pulse-tracing collection treatment circuit, vga controller all are connected fpga chip with data storage; The pulse-tracing collection treatment circuit comprises pulse transducer, analog multichannel switch, precision amplifier, filter circuit and ADC; Pulse transducer, analog multichannel switch, precision amplifier, filter circuit is connected successively with ADC, and ADC is connected on the Avalon bus by the pulse-tracing collection controller.
Power circuit adopts the AC/DC adapter, the AC/DC adapter provides 5V for system, the 1A driving force, the interference of simulation, numerical portion in the system, adopt simulation part and numerical portion to power respectively, and disturb for power circuit has increased the ripple that filter circuit prevents DC voltage, simulation ground and digitally between isolate with magnetic bead, prevent to crosstalk.
Pulse transducer of the present utility model adopts the stiff dough pressure transducer, and model is the HK2000G pulse transducer of Hua Ke company.Precision amplifier is used for amplifying the pulse signal that collects, and selects the instrumentation amplifier AD620 of ADI company for use, and AD620 is fit to the application of pressure-sensing aspect very much, as blood pressure measuring, the bridge circuit signal amplification etc. of pressure sensor.This utility model need be gathered three road pulse signals, and in order to save the cost of conversion of pulse signal analog digital and filtering, at the front end of signal, the design simulation variable connector carries out multiplexed function.Pulse signal is fainter, for less introducing noise, adopts the AD7501 analog switch.ADC(is an analog-digital converter) select for use in the AD678 of band sampling holder, high precision reference power supply, internal clocking and ternary buffered data output.AD678 is 12 bit resolutions, 5 μ S conversion times, and it is simple to have external structure, easy to use, the characteristics that precision is high.
Work process of the present utility model is: pulse transducer is gathered pulse signal, pulse signal is transferred to the signal of telecommunication, through sending into embedded pulse signal processing platform after accurate amplification, filtering, the analog digital conversion, carry out the simple process of pulse signal, be sent to the data storage storage after the processing, perhaps be sent to other main frames by communication interface.
