Description
Technical field
This utility model relates to the medical measurement field, particularly a kind of fully automatic culculating equipment for the calibrating electrocardiograph.
Background technology
Electrocardiograph calibrating principle is that the standard signal that standard set-up (signal generator) produces is inputted tested electrocardiograph, output electrical signals carries out record to the thermal printer that the machine is equipped with after the processing such as electrocardiograph amplifies after receiving signal, filtering, carry out at last waveform and Error Calculation on the manual measurement recorder chart, draw whether qualified conclusion of tested machine.The existing calibration method test signal that waveform, wave amplitude and frequency is different is sent into the laggard walking paper of tested electrocardiograph record, carries out waveform measurement and Error Calculation by rules again, obtains at last verification result.Existing calibration equipment function is more, precision is higher, and Main Problems is:
1) needs manual switchover and adjustment test signal, operation more complicated;
2) need manual measurement output waveform and calculating gauging error, have personal error;
3) need to use the heat-sensitive paper logging test results, have material consumption;
4) verification process is loaded down with trivial details, and calibrating efficient is lower.
Therefore be necessary to carry out the research of automatic Verification technology and method, improve the calibrating efficient of electrocardiograph, reduce testing person's labor intensity.
Summary of the invention
Goal of the invention of the present utility model provides a kind of electrocardiograph automatic calibrator be used to addressing the above problem.
A kind of electrocardiograph automatic Verification machine comprises control module, signaling module, data processing module hardware and tested electrocardiograph; Control module comprises ARM single-chip microcomputer, level shifting circuit, the commutation circuit of leading, electrocardiograph function circuit, signaling module, keyboard, display screen and speech chip, it is characterized in that: the ARM single-chip microcomputer connects respectively level shifting circuit, the commutation circuit of leading, electrocardiograph function circuit, signaling module, keyboard, display screen and speech chip.
The present invention who obtains according to above technical scheme has following advantage or beneficial effect compared with the prior art:
One, is used for the automatic switchover test waveform.
Two, be used for automatically adjusting the technical parameters such as wave amplitude, frequency.
Three, be used for the tested electrocardiograph of automatic operation.
Four, be used for automatically measuring the geometric parameter of output waveform.

Description of drawings
Fig. 1 is electrocardiograph automatic Verification know-why.
Fig. 2 is the control module structure chart.
The specific embodiment
As shown in Figure 1, control module output connects signaling module and tested electrocardiograph, and signaling module output connects tested electrocardiograph, and tested electrocardiograph output connects data processing module hardware, the output of data processing module hardware connects control module, forms a comparatively complicated close loop control circuit.
As shown in Figure 2, the ARM single-chip microcomputer connects respectively level shifting circuit, the commutation circuit of leading, electrocardiograph function circuit, signaling module, keyboard, display screen, speech chip.
Electrocardiograph automatic calibrator hardware is made the box structure that includes some approximate flat boards.Top layer (ground floor) is data processing module hardware, and this data processing module hardware is selected panel computer, notebook computer, smart mobile phone or industrial control computer, and software is developed specially according to practical situation; The second layer is control module and signaling module shared layer, and the two is accomplished on the pcb board; The 3rd layer is the low noise power supply layer.Strict electromagnetic shielding between each layer is in order to avoid the phase mutual interference.
Electrocardiograph automatic Verification process is as follows: first with the corresponding signal output part that inserts automatic calibrator of tested electrocardiogram machine lead wire, next connects RS232 data wire and tested electrocardiograph remote manipulation line and all power lines, then the preheating 10 minutes of starting shooting, take out heat sensitive recording chart and set tested electrocardiograph without the paper running status, start respectively tested electrocardiograph and automatic calibrator and begin calibrating, export at last verification result.
