The operation principle that the various signal waveforms of producing on the at present domestic and international market and using generate equipment is: Wave data is pre-stored in the chip and by table look-up (Lookup Table) and produces analog signal waveform, realizes signal waveform output through simulation amplification circuit again.But there is following defective in present biomedicine signals waveform generation equipment:
1, because the signal waveform data type that prestores is limited and can not edit, so this kind equipment is merely able to produce sine wave, square wave, triangular wave and uses medical signal waveform always.
2, the way of output of these signal waveforms is that N selects 1, and what promptly output waveform can only be for the Wave data that prestores is wherein a kind of, and can not realize that several signal waveforms mix back output according to user's needs.
3, for the signal waveform such as the compound wave group of P-QRS-T of complexity, all multiparameters such as P wave amplitude and interval, QRS wave amplitude and interval, T wave amplitude and interval, P-R interval, Q-T interval, S-T section can't be adjusted respectively.
4, this signal waveform generates equipment and can not produce the composite signal waveform that is mixed with noise, direct current offset, interchange interference, burst etc., more can't be edited the parameter of mixed signal by the user arbitrarily.

That testing procedure is meant selected test signal and literal note and the controlled action-item of signal waveform output time.The user enumerates the interface by test signal and browses the testing source storehouse, and select the interface from the test signal of enumerating, to select test signal by test signal, also can describe editing interface and come the additions and deletions literal to reach the purposes such as application note of note about corresponding steps by testing procedure.
In conjunction with shown in Figure 3, the workflow of testing scheme generation module 42 is as follows:
Test signal in step S201, the testing procedure editing machine 422 is enumerated the test signal in the read test signal source storehouse, interface 421, all test signals in the testing source storehouse 421 are enumerated in the interface in this test signal and are listed the selection for the user with tabular form, and the user can select any test signal from testing source storehouse 421.
Testing procedure in step S202, the testing procedure editing machine 422 selects the interface to provide the test signal that the user is selected to add among the specific testing procedure.
Testing procedure in step S203, the testing procedure editing machine 422 is described editing interface provides the user that testing procedure is described the adjustment editor.
The user can be according to actual needs, and repeating step S201 selects a plurality of test signals to edit adjustment to step S203, has the testing scheme of a plurality of testing procedures with generation.
Step S204, user determine testing procedure by confirming test signal and note thereof; The user is by additions and deletions and determine that testing procedure realizes a plurality of testing procedures in the testing scheme, and the order that can adjust each testing procedure realizes the sequential requirement of signal waveform output in the test process; Form unit 423 by testing scheme at last and generate testing scheme.
Hence one can see that, generates testing scheme on existing test signal basis, can specified order, select test signal and edit the literal note as testing procedure, and store and the test transmission scheme in the mode of testing scheme definition data structure.User's use test scheme realizes the signal waveform output of unlike signal type and parameter, changes signal waveform output flexibly by the control testing procedure, and does not need interrupt test to revise signal type and parameter, to satisfy complicated test needs.
In addition, the testing scheme of storage can be read and transmit, and also can be deposited in RAM and be used to signal waveform output, also can be used to generate other testing scheme.The user can select interface or file deployment to select some testing schemes to realize a series of signal waveform output from the testing scheme storehouse by testing scheme.
