Description
Technical field:
The utility model relates to a kind of wireless digital displacement transducer, and it belongs to sensor technical field.
Background technology:
Existing similar displacement transducer all adopt lead with the simulation of sensor output or digital signal be sent to electronic box carry out computing by electronic box then and handle after just export measurement result and use for the rear end or show, be that this is that a kind of wired mode transmits data, the situation that sensing need be rotated or lead inconvenience arrives when meeting just can't be used; In addition, dispatch from the factory Shi Junxu and the electronic box that matches of existing displacement transducer can use after demarcating, and more during emat sensor, must sensor be demarcated again with electronic box by sensor manufacturer.As disclosed a kind of " displacement transducer " in No. the 89209261.0th, the Chinese patent, though it also belongs to a kind of sensor of displacement, but it has only solved the problem that makes that sensor is sensitive more, it still belongs to a kind of sensor of wired class, therefore, still there is above-mentioned defective in it, in the suitable also inconvenience of using of some occasions.In No. the 200410022895.5th, the Chinese patent, recorded and narrated a kind of " inductance fm formula intelligent digital displacement transducer ", though this its transmission of sensor is digital signal, the length of test result and transmission cable is irrelevant, but its sensor also must with a specific electricity supporting use, and need utilize cable to transmit data.
Summary of the invention:
The purpose of this utility model is to provide a kind of can realize direct outputting measurement value, and does not need the wireless digital displacement transducer of cable transmission.
The purpose of this utility model is achieved in that
A kind of wireless digital displacement transducer, it comprises shell, a gauge head that is arranged in the shell, and an end of side head is exposed to outside the described shell, and the telefault group, power supply and the digital processing system that are arranged on the other end of gauge head, described coil groups is made up of two groups of telefaults; Described digital processing electric system comprises that a differential type inductance fm circuit and one can be converted into the computing of inductor oscillating frequency change the gauge head displacement and demarcate the single-chip microcomputer of setting; The output terminal of described single-chip microcomputer also is connected with the transmitter that an operation result with single-chip microcomputer is transmitted into control center or host computer.
Described differential type inductance fm circuit comprises that produces the oscillator that electric wave loads on telefault generation inductance; The variation of this magnetic flux is converted to the isolation shaping circuit of signal in the regular arteries and veins and converts pulse signal to digital counter.
Be arranged with spring on described gauge head, the other end of described spring is stuck on the termination of shell.
Exposed junction at described gauge head is provided with collar, is arranged at described spring between the termination of collar and shell.
Described transmitter is a microwave emitter.
The signal of output of the present utility model directly is exactly a measured value, and this measured value does not need can directly use through computing again.Change the utility model in the use and do not need to demarcate again and do not influence measuring accuracy, also raise the efficiency and reduce cost.The utility model adopts wireless mode to transmit data, and the application of displacement transducer is more flexibly with wide.

Fig. 1 is a structural representation of the present utility model
Fig. 2 is a circuit block diagram of the present utility model
Embodiment:
Be embodiment of the present utility model with accompanying drawing 1,2 below, the utility model be further detailed:
A kind of wireless digital displacement transducer, it comprises that 7, one on shell is arranged on the gauge head 1 in the shell 7, an end of gauge head is exposed to outside the described shell, and the telefault group, power supply and the digital processing system that are arranged on the other end of gauge head 1.Be arranged with spring 2 on described gauge head 1, the other end of described spring is stuck on the termination of shell 7.For better control spring, the exposed junction at described gauge head 1 is provided with collar 11 in the present embodiment, is arranged at described spring between the termination of collar and shell.Described coil groups forms 3,4 by two groups of telefaults; Described digital processing electric system comprises that a differential type inductance fm circuit and one can be converted into the computing of inductor oscillating frequency change the gauge head displacement and demarcate the single-chip microcomputer 5 of setting; The output terminal of described single-chip microcomputer 5 also is connected with the transmitter 6 that a computing calibration result with single-chip microcomputer is transmitted into control center or host computer; Described transmitter 6 is a microwave emitter.Described differential type inductance fm circuit comprises that produces the oscillator that electric wave loads on telefault generation inductance; The variation of this magnetic flux is converted to the isolation shaping circuit of regular pulse signal and converts pulse signal to digital counter.
Basic functional principle of the present utility model is as follows:
Gauge head 1 makes telefault group 3 and telefault group 4 produce the inverse change of frequency along the displacement of axial generation.Spring 2 can provide ergometry.Be provided with digital processing circuit in shell, it comprises power supply, and differential type inductance fm circuit and single-chip microcomputer, described single-chip microcomputer can be realized the frequency change computing of C, two coil groups of D is become the gauge head displacement; Transmitter 6 is transmitted into control center or host computer with the operation result of digital processing circuit.
As shown in accompanying drawing 2, the conversion and the flow process of signal of the present utility model are as follows: gauge head 1 perception change in displacement, produce displacement, and oscillator produces electric wave and loads on telefault group 3 or telefault group 4 generation inductance.This moment, displacement converted the variation of magnetic flux to, and the isolation shaping circuit converts the variation of this magnetic flux to regular pulse signal, and counter converts pulse signal to numeral again.Because telefault group of the present utility model has two, the computing of the two paths of data that obtains thus process single-chip microcomputer obtains the value of displacement, offers transmitter 6, is transmitted into the place of the data that need then by transmitter.
