That is, with this driving device, it is possible to realize the auto-zero initialization function in the state where the circumferential sensors are naturally contracted, so that the output values of the circumferential sensors in the naturally contracted state are made uniform, and the purpose of eliminating the individual difference of the sensors when the circumferential sensors are driven is achieved directly.
After the development of the circumference sensor driving device is completed, circuit parameters do not need to be adjusted in the using process, and the circumference sensor driving device can be adapted to circumference sensors of different models, so that the production efficiency and the measurement efficiency are greatly improved.
The circumference sensor driving device can also provide information for an external measurement application device, so that the external measurement application device can better perform measurement.
The circumference sensor driving device is used as an intermediate layer between an external measurement application device and the circumference sensor, and the two are connected to form an integral closed-loop structure. The closed-loop decoupling concept can be applied to more application scenes, wherein the decoupling is carried out between the circumference sensor and an external measurement application device, and the initial value of the circumference sensor is uniform no matter how the circumference sensor is replaced for the external measurement application device.

When the circumference sensor is in a natural contraction state, the light guide member 11 is bent and the light escape grooves 12 are located at one side of the bent outer circumference of the light guide member 11, and due to the presence of the light escape grooves 12, a part of light of a specific incident angle escapes from the light escape grooves 12 to be dissipated, so that a part of light flux of the circumference sensor is lost when the circumference sensor is in the natural contraction state.

When the circumference of the object to be measured is reduced, the elastic base 23 drives the light guide element 11 to rebound and contract, and the light guide element 11 tends to bend towards the direction far away from the light ray escape groove 12, so that the surface of the light ray escape groove 12 is stretched and gradually tends to the light ray escape groove 12 to be vertical to the incident light path, more light rays escape from the light ray escape groove 12 to the skin layer to be dissipated, the light flux is reduced, and the change of the light flux is monotonous.
Whether the circumference sensor is expanded outward or contracted inward, the change of the luminous flux of the light guide member 11 is monotonously changed, and the change is continuously changed, so that the degree of bending of the measured object can be judged by the luminous flux of the light guide member 11.
The driving input of the circumference sensor is a current value, and the light emitting quantity of the circumference sensor is in a direct proportion relation with the driving current; the output of the circumference sensor is a current value, under the condition that the power supply voltage is not changed, the output current of the circumference sensor is in a direct proportion relation with the luminous flux received by the surface, namely the stretching and expanding degree of the circumference sensor can be measured by measuring the magnitude of the output current, and the output current is in a direct proportion relation with the stretching and expanding degree, so that the measurement accuracy is ensured. The effect of monitoring the change of the circumference in real time for a long time is achieved by monitoring the magnitude of the output current in real time.

s8, if | delta V | is larger than or equal to epsilon and delta V >0, the core control device reads the adjustment step length delta U and calculates Ud as Ud plus delta U, and outputs the calculated driving voltage information Ud to the voltage regulation device, and then the step of outputting the driving current is carried out;
s9, updating voltage regulation set value record Urec: the core control device saves the current driving voltage information Ud to the nonvolatile memory device and replaces the original voltage regulation set value record Urec.

The data is continuously monotonously changed when the circumference of the measured object changes, so that the automatic zero-resetting initialization of the output value of the circumference sensor in the natural contraction state is necessary for measuring the circumference change (the zero-resetting proposed herein does not mean that the current value or the voltage value is equal to zero, but means that under the fixed measurement application scene, the output value Vout of the circumference sensor in the natural contraction state-the initialization expected output value Vexpect < error epsilon), namely, each circumference sensor can output approximately equal Vout in the natural contraction state. The circumference sensor is in a natural shrinkage state, namely an initial state, and can achieve the effect of convenient measurement. In the naturally contracted state using different circumference sensors, each circumference sensor can output approximately equal output voltage Vout, which is essentially different from the driving device existing on the market.
