Electromagnetic valve is mainly used in air bag and fills aerofluxus in external counterpulsation apparatus; Generally all there is certain mechanical delay (50-100ms) in electromagnetic valve; Existing ECP system according to concrete time-delay situation, carries out fixed compensation (i.e. inflation in advance) to the mechanical delay of electromagnetic valve when producing.
Yet the increase of the mechanical delay of finding electromagnetic valve in actual use along with service time can change, and adopts the constant time lag compensation can produce an inflation point inaccuracy, influences therapeutic effect, and the low shortcoming of safety.
The utility model content
The purpose of this utility model is: to the problem of above-mentioned existence; The electromagnetic valve time-delay dynamic compensating device of a kind of ECP system is provided; It has realized the dynamic compensation to the electromagnetic valve delay time; Make that the inflation point is more accurate, the therapeutic effect of ECP system is better, and safety is higher.
To achieve these goals; This utility model provides the electromagnetic valve dynamic delay compensation arrangement of a kind of ECP system; It is characterized in that: form by pressure transducer, controller, photoisolator and drive circuit; The outfan of wherein said pressure transducer connects the input of said controller, and the outfan of said controller connects said photoisolator, and the outfan of said photoisolator connects said drive circuit;
Said pressure transducer is used to detect the pressure in the air bag, and pressure signal is transferred to said controller;
Said controller is used to send pulse signal and gives said photoisolator, and calculates delay time at said pressure signal during greater than threshold value, when said delay time changes, upgrades delay time;
Said photoisolator is used for said pulse signal is carried out being transferred to said drive circuit after the photoelectricity isolation processing;
Said drive circuit is used for sending the driving signal and gives said electromagnetic valve, the action of control electromagnetic valve, airbag aeration.
In sum, owing to adopted technique scheme, the beneficial effect of this utility model is:
Adopts pressure sensor detects the pressure of airbag aeration mouth; Whether controller judges pressure signal greater than threshold value, when pressure signal recomputates delay time during greater than threshold value, when delay time changes, upgrades delay time; Thereby realized dynamic compensation to the electromagnetic valve delay time; Make that the inflation point is more accurate, the therapeutic effect of ECP system is better, and safety is higher.

For the purpose, technical scheme and the advantage that make this utility model is clearer,, this utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation this utility model, and be not used in qualification this utility model.
As shown in Figure 1; The electromagnetic valve time-delay dynamic compensating device of this ECP system is made up of pressure transducer 1, controller 2, photoisolator 3 and drive circuit 4; Wherein the outfan of pressure transducer 1 connects the input of controller 2, and the outfan of controller 2 connects the input of photoisolator 3, and the outfan of photoisolator 3 connects the input of drive circuit 4; The outfan of drive circuit 4 connects the input of electromagnetic valve 5, and the outfan of electromagnetic valve 5 connects the input of air bag 6.Pressure transducer 1 is used to detect the pressure of air bag air inlet and pressure signal is transferred to controller 2; Controller 2 is used to send pulse signal and gives photoisolator 3, and calculates delay time at pressure signal during greater than threshold value, when delay time changes, upgrades delay time; Photoisolator 3 is used for this pulse signal is carried out being transferred to drive circuit 4 after the photoelectricity isolation processing; Drive circuit 4 is used for sending the driving signal and gives electromagnetic valve, the action of control electromagnetic valve, airbag aeration.
As shown in Figure 2, the operation principle of this utility model is:
Controller sends pulse signal, and this pulse signal is transferred to drive circuit after photoisolator is handled, the control drive circuit works, and the drive circuit output drive signal is given electromagnetic valve, the action of control electromagnetic valve, airbag aeration;
Pressure transducer is gathered the pressure in the air bag; And pressure signal is transferred to controller; Controller judges that pressure signal is whether greater than threshold value: if judge that pressure signal is greater than threshold value; Time mechanical delay of then representing electromagnetic valve possibly change, and controller recomputates delay time, and judges further whether recomputate the delay time that draws changes; When recomputating the delay time that draws and change, upgrade delay time, thereby realized dynamic compensation the electromagnetic valve delay time;
If judge when pressure signal is less than or equal to threshold value, then the pressure of pressure transducer repeated acquisition airbag aeration mouth.
The above is merely the preferred embodiment of this utility model; Not in order to restriction this utility model; Any modification of being done within all spirit and principles at this utility model, be equal to replacement and improvement etc., all should be included within the protection domain of this utility model.
