Description
Technical field
The utility model relates to a kind of head controlling device of peeping, and especially a kind of trailing type is peeped head controlling device.
Background technology
It is to detect the position signalling of motor and the position signalling of rocking handle compares by the single-chip microcomputer of peeping head controlling device that traditional trailing type is peeped technology that head controlling device adopts, if result does not relatively reach the requirement of setting, signal feedback is to electric control system, then control the rotation of motor, when the position signalling of the position signalling of motor and rocking handle reached requiring of setting, motor stopped operating.This kind mode is controlled more complicated, and hardware and software all must meet the demands, and inevitable single chip microcomputer halt causes fault.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of circuit control mode simply, can not crash and cause the head controlling device of peeping of fault.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: trailing type is peeped head controlling device and is comprised mechanical driving part, motor and circuit control section, it is characterized in that: the circuit control section is formed by connecting by potentiometer, operational amplifier, level-conversion circuit and motor control chip, one end of potentiometer is by ground, the high power supply potential of another termination, the middle part of potentiometer is connected with operational amplification circuit respectively, the output termination level-conversion circuit of operational amplification circuit, level-conversion circuit is connected with the input end of motor control chip.
In above-mentioned technology, described potentiometer comprises motor synchronizing potential device and hand-rail type potentiometer, motor synchronizing potential device and the motor coaxle heart rotate, one end of motor synchronizing potential device, hand-rail type potentiometer is by ground, the high power supply of another termination, the middle part of motor synchronizing potential device, hand-rail type potentiometer is connected with operational amplification circuit respectively.
The beneficial effects of the utility model: the circuit control section is simply effective, the steering logic clear and definite, and reliability is high.

Fig. 1 is the utility model circuit part control chart.
Embodiment
Embodiment 1
trailing type is as shown in Figure 1 peeped head controlling device, it comprises mechanical driving part and circuit control section, the circuit control section is by potentiometer, operational amplifier, level-conversion circuit and motor control chip are formed by connecting, potentiometer comprises motor synchronizing potential device and hand-rail type potentiometer, motor synchronizing potential device and the motor coaxle heart rotate, motor synchronizing potential device, one end of hand-rail type potentiometer is by ground, the high power supply of another termination, motor synchronizing potential device, the middle part of hand-rail type potentiometer is connected with operational amplification circuit respectively, the output termination level-conversion circuit of operational amplification circuit, level-conversion circuit is connected with the input end of motor control chip.
When rotating the hand-rail type potentiometer by wind, the discharge circuit input has just had pressure difference signal, during for positive pressure differential, positive level output is arranged, and controls the motor forward rotation, makes motor synchronizing potential device SMIS turn to the position identical with the wind potentiometer; When being Negative Pressure Difference, negative level output is arranged, by level translation, control the Electric Machine Control backward rotation, make the motor synchronizing potential device SMIS backward rotation position identical with the wind potentiometer.So just make motor synchronizing potential device and hand-rail type potentiometer form servomechanism, by running part, make the orientation of wind consistent with the orientation of peeping head.
