Described main frame is provided with two kinds for the treatment of patterns, and described main frame carries out two kinds of switchings for the treatment of pattern by mode selector switch, and shows by dual-colored LED display lamp the treatment pattern of choosing.
Treatment pattern:
One: 3 electric control valve of pattern is opened (inflate simultaneously in three chambeies) simultaneously, in three cavitys for the treatment of trousers, be inflated to setting treatment pressure (inflationtime 30 seconds simultaneously, the blowing pressure 0-30KPa, available high accuracy pressure regulator valve on-line control) also keep (30 seconds retention times), then aerofluxus (evacuation time 15 seconds).Follow three cavity repeated inflation, maintenance, exhaust process, so circulation is carried out, until intervalometer timing arrives, machine stops, treatment end.
Two: 3 electric control valves of pattern are successively opened, and first give the pressure that the ankle chamber for the treatment of trousers is inflated to setting (inflationtime 30 seconds, the blowing pressure 0-30KPa, can on-line control) and keep (i.e. not aerofluxus); Then give the pressure that the shank chamber for the treatment of trousers is inflated to setting (inflationtime 30 seconds, the blowing pressure 0-30KPa, can on-line control) and keep (i.e. not aerofluxus); Finally give the pressure that the thigh chamber for the treatment of trousers is inflated to setting (inflationtime 30 seconds, the blowing pressure 0-30KPa, can on-line control).Then three cavitys keep the blowing pressure to the time (30 seconds retention times) of setting, the aerofluxus (evacuation time 15 seconds) simultaneously of last three cavitys.Then repeat said process, so circulation is carried out, until intervalometer timing arrives, machine stops, and treatment finishes.
Timing starting/stopping: adopting the longest timing mechanical timer of 90 minutes (time length scalable), the mechanical timer being arranged on therapeutic instrument coordinates software program realize the timing starting of the therapeutic instrument of fainting and stop.
Referring to Figure 10, the software control procedure of single-chip microcomputer mainly shows that by: key scan (model selection) subprogram, LED (pattern demonstrations) subprogram, the subprogram for the treatment of pattern, time delay subroutine, definition status detection subprogram form.
Program operating procedure:
Whether 1, program starts first to do key scan, detect treatment model selection button and pressed down;
If 2 treatment model selection buttons are pressed down, time delay a period of time, do elimination dithering process, avoid maloperation, after determining that button is pressed, enter the treatment pattern of choosing, corresponding LED light is bright;
3 then detect the duty (setting the treatment cycle time by intervalometer) of intervalometer, if intervalometer starts, and the treatment pattern (if intervalometer does not start, machine is in halted state) that system operation is chosen;
4, meeting in service constantly detects intervalometer state, if intervalometer always in starting state, program just circulation is always carried out the treatment pattern of choosing;
5, when intervalometer being detected and stop, buzzer sends prompt tone, and machine quits work.
