Description
Technical field:
The present invention relates to a kind of sensor, particularly a kind of intelligent angular displacement sensor.
Background technology:
At present, the direction of giving priority to is equipped in digging: coal mining remote control technology, the monitoring in real time of the remote online of coalcutter running status, fault diagnosis and Long-distance Control; Online control and long-distance remote control control technology that visual telecontrol engineering of coal petrography tunnel cantilevered digging device and down-hole fully-mechanized mining working are mined and equipped.Research and development aspect the coal mining remote control technology are just at the early-stage, also do not have the core technology of this respect on top of, and its sensing technology is one of core technology.Consider the working environment of mining machinery under the coal mine; Condition is complicated and changeable; Be accompanied by many unfavorable factors such as high temperature, high humidity and high-intensity oscillation, exploitation adapts to the high reliability position-detection sensor under the abominable working environment, realizes the slew gear working position of mining machinery is detected; And these problems slew gear working position that is embodied in mining machinery that focuses mostly on is detected on the link, and the efficient and reliability of sensor becomes the key issue that solves this link.This trial and exploitation is on the one hand also being done by mining machinery manufacturer domestic in the period of nearly three, five; To transplant the ground detection means is main; Adopting forming techniques such as gyroscope, rotary encoder is means, is equipped with the control corresponding system to test, but does not all have successful case.
Summary of the invention:
The objective of the invention is based on the intelligent angular displacement detecting sensor under the above-mentioned working environment, but this sensor not only is used for being widely used in other occasion under this particular surroundings.The present invention has permanent magnet and the anti-external interference property of magnetic control tongue tube is strong, and good leak tightness is shock-resistant, and vibration resistance is high temperature resistant, the simple and direct characteristics such as reliable of easy-to-connect.
Above-mentioned purpose realizes through following technical scheme:
Intelligent angular displacement sensor; Its composition comprises: housing and mechanical speedup enlarger; Described mechanical speedup enlarger drives the Moving plate of inlaying permanent magnetism tablet; Be fixedly connected on the described housing and inlay magnetic control tongue tube input price fixing, be fixedly connected vibration absorber on the described housing, described shock attenuation device is fixedly connected the single-chip microcomputer signal processing system.
Described intelligent angular displacement sensor, described single-chip microcomputer signal processing system are precision resistance partial pressure type signal processing systems.
Described intelligent angular displacement sensor, described single-chip microcomputer signal processing system and sensor body can become one, and perhaps process separate form.
Beneficial effect of the present invention:
The present invention has permanent magnet and magnetic control tongue tube, and anti-external interference property is strong, and good leak tightness is shock-resistant, and vibration resistance is high temperature resistant, and easy-to-connect is simple and direct reliable.
Input shaft is passed through in angular displacement to be detected; Drive the Moving plate 2 of inlaying magnetic sheet via mechanical speedup enlarger; Inlay magnetic control tongue tube input price fixing 3 and be fixed on the housing, single-chip microcomputer 4 electrical parts such as grade are fixed on the housing through vibration absorber 6 (this figure takes spring damping).Moving plate adopts NULL to process, and magnetic sheet is embedded on the Moving plate, and except facing the tongue tube side, all the other five are all carried out the magnetic field sealing by NULL to magnetic sheet, form a specific uniform magnetic field, to control corresponding tongue tube action; Tongue tube arrangement on the price fixing adopts the equidistant alternative arrangement of many circles and arranges quantity.
Pivot angle to be detected transmits the rotary oscillation angular displacement through multimachine tool speedup enlarger and amplifies, and drives Moving plate and rotates.When Moving plate and price fixing do not have relative motion; Magnetic control tongue tube on the price fixing is in shutoff or conducting state does not change; When mechanical speedup enlarger driving Moving plate rotatablely moved with price fixing generation relative motion, the magnetic control tongue tube on the price fixing was in continuous conducting-off state, then produces the pulse signal of break-make; Utilization closes on the break-make sequencing of two magnetic control tongue tubes, judges sense of rotation.The tongue tube quantity of any time position conducting can be less than one.
During the single-chip microcomputer signal processing mode: shown in accompanying drawing 2; Adopt SCM system that the output signal of magnetic control tongue tube is gathered, stored and handles; This mode requires an I/O interface on the corresponding single-chip microcomputer of each tongue tube on the price fixing; The quantity of tongue tube and the size of speed increasing ratio are decided by the resolution that detects, and the tongue tube quantity of co-located conducting can be arbitrarily in theory simultaneously.When Moving plate and price fixing do not have relative motion; Tongue tube on the price fixing is in shutoff or conducting state does not change; When Moving plate and price fixing produced relative motion owing to mechanical speedup enlarger drives, the tongue tube on the price fixing was in continuous conducting-off state, outside transmission pulse signal.Through detecting the sequencing of adjacent two reed switch conductions, judge sense of rotation, according to the quantity of acquisition pulse signal, then export angle of oscillation tolerance.
During precision resistance partial pressure type signal processing mode: shown in accompanying drawing 5; Adopt high-precision resistance string to receive on the magnetic control tongue tube, through the rotation of Moving plate, the tongue tube break-make of relevant position on the control price fixing; Connect corresponding loop; Utilize voltage divider principle to export corresponding fixed voltage value, the continuous equally spaced angle of oscillation tolerance of exportable 0～5V voltage (characteristic of output signal is that change output voltage signal along with displacement presents the successive steps rule and changes).
