The utility model content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide the ultrasonic control system that a kind of failure rate is low, maintenance is easy.
In order to achieve the above object, the technical solution adopted in the utility model is such: a kind of ultrasonic control system, comprise first Hall switch, second Hall switch, the 3rd Hall switch, the 4th Hall switch, the PLC controller, signal output unit, driving, wherein, first Hall switch, second Hall switch, the 3rd Hall switch, the output of the 4th Hall switch connects the input of PLC controller, the output of PLC controller connects the input of signal output unit, the output of signal output unit connects driving, and driving connects first Hall switch, second Hall switch, the 3rd Hall switch, the 4th Hall switch forms the loop.
The utility model has been cancelled the mechanical stroke switch of conventional ultrasound control system, employing has the Hall switch of metal induction, when the driving that is mounted with chip arrives, Hall switch will be imported the PLC controller as triggering signal with the signal of sensing, this contactless control mode has reduced failure rate, and maintenance is also convenient; The PLC controller has substituted all relays of cancellation of conventional ultrasound control system, adopts the contactless control mode of semiconductor, and this control mode has also reduced failure rate, when the PLC controller damages, directly changes the PLC controller, and maintenance is also convenient; In addition, adopt PLC to carry out programming Control, use a controller just can control the whole ultrasonic system, control is simple, has guaranteed systematic function.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are:
1, failure rate is low; 2, maintenance is easy; 3, can improve the performance of The whole control system.
Description of drawings
