The specific embodiment
Referring to Fig. 1, muscular strength EMG signal real-time of the present invention collection and while device shown comprise main control computer 1, main display 2, electromyographic signal collection electrode 3 and bluetooth muscular strength acquisition module 4.Main display 2 links to each other with main control computer 1 signal of telecommunication, and electromyographic signal collection electrode 3 links to each other with main control computer 1 through signal connecting line; Bluetooth muscular strength acquisition module 4 links to each other with main control computer 1 wireless telecommunications.Be provided with muscular strength signal acquisition module 11, electromyographic signal collection module 12, muscular strength signal display module 13 and electromyographic signal display module 14 in the main control computer 1; Muscular strength signal acquisition module 11 wherein links to each other with 4 wireless telecommunications of bluetooth muscular strength acquisition module; Electromyographic signal collection module 12 links to each other with electromyographic signal collection electrode 3 through signal connecting line, and muscular strength signal display module 13 links to each other with main display 2 through signal connecting line respectively with electromyographic signal display module 14.
Bluetooth muscular strength acquisition module 4 among the present invention comprises pressure transducer 41, signal amplification module 42 and bluetooth sending module 43; Pressure transducer 41, signal amplification module 42 and the bluetooth sending module 43 order signals of telecommunication link to each other and become one, and muscular strength signal acquisition module 11 includes the bluetooth receiver module.
Muscular strength signal display module 13 and 14 collaborative works of electromyographic signal display module among the present invention; Muscular strength signal and electromyographic signal are simultaneously displayed on the same interface of main display; As shown in Figure 2; Among the figure, superposed up-down vibration curve is the electromyographic signal line, and the wave curve that is positioned at the bottom is the muscular strength holding wire.
Practical implementation step of the present invention is following:
Electromyographic signal collection electrode and bluetooth muscular strength acquisition module are attached to patient's muscle surface respectively.Starting drive then.
The A/D that at first clicks the menu bar the inside is provided with; Can produce a pci card dialog box is set this moment; The user according to oneself demand in of the relevant setting of this dialog box to the PCI capture card; Comprise the setting of the amplitude, the translation type after the sampling, the triggering mode of sampling etc. of sample frequency to the PCI capture card, sampling, behind the hit OK its corresponding setting is preserved.
Click the A/D sampling number of menu bar, this moment, the sampling number dialog box let the user according to the demand of oneself the counting of sampling that PCI gathers carried out corresponding setting through this dialog box, promptly can preserve its corresponding setting behind the hit OK.
The click bluetooth parameters is provided with; Can produce a bluetooth dialog box is set this moment; The user is provided with bluetooth parameters in this dialog box according to the demand of oneself; Comprise the setting of the switch etc. of port to serial ports, baud rate, check bit, data bit, position of rest, bluetooth, behind the hit OK its corresponding setting is preserved.
After disposing accordingly through 12 pairs of PCI capture cards, bluetooth parameters, promptly collecting work can have been begun.Only need promptly can begin to carry out the collection and the demonstration work of electromyographic signal and muscular strength signal through clicking the top run button in main interface (object of CDynamomterView class): through one independently thread electromyographic signal is gathered; Through blue tooth interface the muscular strength signal is gathered in addition; So just accomplished the collecting work to electromyographic signal and muscular strength signal simultaneously, electromyographic signal and muscular strength signal just can show in an interface simultaneously in the process of gathering.
After disposing accordingly through 12 pairs of PCI capture cards, promptly collecting work can have been begun.Only need promptly can begin to carry out the collection and the demonstration work of myoelectricity muscular strength signal through the run button of clicking above the main interface (object of CDynamomterView class).
The collection of electromyographic signal and the flow process of demonstration are following:
A, through calling OnAdintRun () function, the groundwork of this function is: 1, open equipment: produce a prompting if the equipment of opening is made mistakes and open the information of failure; 2, obtain configuration of devices, promptly obtain the configuration of user, carry out the work of closing the PCI capture card if obtain configuration failure to the PCI capture card; 3, driver Memory Allocation and locking; 4, user data is gathered the Memory Allocation and the locking of required variable; 5, confirm the interrupt event type, and it is set can interrupts (if make mistakes, then not only want closing device at this, and must release and the variable that discharges front definition and locking between the operation of closing device); 6, beginning interrupt mode transfer of data; 7, after top preparation is accomplished,, just can create user thread and carry out data acquisition, at user thread UserThread of this establishment if the time type allows to interrupt.
B, the main work of separate threads UserThread are the states that detects the work that PCI gathers, for example, when interrupting then PCI carry out the collection of data, when exchanges data enables, carry out the conversion of data etc.
The whole process of c, collection is through interrupting completion.AdBufChangeEvent () event response function; Initialization PT_FAIChek structure and call DRV_FAICheck function inspection and the current state of return data collection in this function: and carry out data acquisition through calling the DRV_FAITransfer function; When the buffer area completely goes up 1/2; Or 1/2 o'clock down; In adBufChangeEvent () function,, WM_ADOPTEND message is responded through message response function: OnAdoptend () through sending WM_ADOPTEND message, and from cushioning regional taking-up value and changing accordingly.Up to when the pixel of the horizontal direction that has surpassed drawing area from the number that cushions the value that the zone reads the time,, in OnDraw () function, respond through sending message UpdateWindow ().Signal to collecting is drawn, after whole drawing area is all completed, through redrawing the drafting of carrying out next time.
The collection flow for displaying of muscular strength signal is following:
A, through calling OnAdintRun () function, this function is mainly realized whether hyphen of main frame and equipment, if just connect with 3 bluetooth parameters that are provided with serial ports is carried out initialization operation.
B, initialization finish the back and write the serial ports function through calling; Write the instruction of Handshake Protocol to serial ports; If the agreement that the agreement that writes and slave computer are set is consistent, slave computer equipment will be with the mode response instruction that interrupts so, and sends the data that collect and arrive host computer.
The interruption that c, host computer are sent through the detection slave computer is gathered and is preserved the data of slave computer transmission, and through the ondraw function data that collect is drawn.
The collection of muscular strength signal and electromyographic signal and demonstration have simultaneously just been realized through above step.
