Description
Technical field
The present invention relates to a kind of device of inspected object relative position, judge two kinds of objects problem that whether position coincide when assembling in order to solve.
Background technology
When two kinds of objects that slide relatively are installed, judge and install when whether putting in place that the relative position information of two kinds of objects becomes very important discrimination standard.Designed in the prior art and utilized magnetic position sensor; Its method is on an object, Hall element to be installed; A magnet is installed on the another one object, and when two object spaces changed, the magnetic field amount that Hall element receives was different; Thereby cause the variation of its current value or magnitude of voltage, through the current value of measuring Hall element or the relative position that magnitude of voltage just can calculate two objects.The shortcoming of such method is that working environment is had relatively high expectations, and receives noise or other outer influences of disturbing easily, causes measured value reliable and stable inadequately.
Summary of the invention
The objective of the invention is shortcoming, a kind of device of inspected object relative position is provided to prior art.
The present invention realizes through following technical scheme:
In object relative position sensing detection part, the lower end object to be detected is installed; The upper end object to be detected moves right; When the center line of non-contact capacitive formula liquid level sensor arrived the left margin of sealing water box, the pilot lamp of non-contact capacitive formula liquid level sensor was lighted, and showed that the installation site coincide.
Structure of the present invention comprises: object relative position sensing detection part and Single-chip Controlling part, object relative position sensing detection part is made up of connection line, lower end object to be detected, the sealing water box of upper end object to be detected, non-contact capacitive formula liquid level sensor, non-contact capacitive formula liquid level sensor and single-chip microcomputer.
The mounted on surface non-contact capacitive formula liquid level sensor of upper end object to be detected, the lower surface of lower end object to be detected are installed sealing water box, and non-contact capacitive formula liquid level sensor partly links to each other with Single-chip Controlling through connecting line.
Non-contact capacitive formula liquid level sensor comprises: accessory power outlet, pilot lamp, benchmark gauge hole, accessory power outlet comprises: 5V working power end VCC, sensor signal output terminal, earth terminal GND.When the half of liquid level to be detected above non-contact capacitive formula liquid level sensor area, pilot lamp is lighted, sensor signal output terminal output low level.The benchmark gauge hole is used to adjust the sensitivity of non-contact capacitive formula liquid level sensor, promptly adjusts the ratio of the shared non-contact capacitive formula liquid level sensor area of liquid level to be detected.
The 5V working power end VCC of non-contact capacitive formula liquid level sensor; The sensor signal output terminal; Three lines of earth terminal GND are connected to the sensor gang socket P1 in the Single-chip Controlling part; Wherein the 5V working power end VCC of non-contact capacitive formula liquid level sensor is connected to 1 pin of sensor gang socket P1; The sensor signal output terminal of non-contact capacitive formula liquid level sensor is connected to 2 pin of sensor gang socket P1, and the earth terminal GND 3 of non-contact capacitive formula liquid level sensor is connected to 3 pin of sensor gang socket P1.
Single-chip Controlling partly comprises: single-chip microcomputer U1, sensor gang socket P1, single-chip microcomputer U1 input signal pull-up circuit R1, R2, sensor signal input pin PE4, single-chip microcomputer U1 crystal oscillating circuit Y1, C29, C30, single-chip microcomputer U1 electric source filter circuit C27, C28, power supply VCC_5V and ground connection.
The pull-up circuit R1 of Single-chip Controlling part, R2 is used for guaranteeing from the stability of sensor input signal to the PE4 input pin of single-chip microcomputer U1.Single-chip microcomputer U1 adopts ATmega128-16AC, and by Y1, the circuit that C29, C30 connect into provides system clock for single-chip microcomputer U1, and by C27, the circuit that C28 connects into is that the working power of single-chip microcomputer U1 provides filtering, prevents external interference and causes working power unstable.
Single-chip microcomputer U1 at first accomplishes initialization, and its fundamental purpose is to accomplish the configuration of input and output pin, Abort Timer, is set to low level and triggers interruption.When upper end object to be detected and detected material body position, lower end coincide, sensor signal output terminal output low level, 2 pin of the socket P1 of Single-chip Controlling part also are low level; Through pull-up circuit R1, be input to the PE4 pin of single-chip microcomputer U1 behind the R2, this moment, the PE4 pin was a low level; Because the PE4 pin is the INT4 of single-chip microcomputer U1; When initialization, be provided with low level and trigger interruption, interrupt, judge that upper end object to be detected and detected material body position, lower end are identical so single-chip microcomputer U1 triggers.When misfitted upper end object to be detected and detected material body position, lower end, the PE4 pin was a high level, and the INT4 of single-chip microcomputer U1 is not triggered, and systemic circulation continues to detect.
The invention has the beneficial effects as follows:
Adopt of the collection of non-contact capacitive formula liquid level sensor, because this sensor adopts pure electronic circuit formula structure, on-mechanical working method as the front-end position signal; The stable performance life-span is durable, high stable, high sensitive; Anti-interference is good, does not receive outside electromagnetic interference, is fit to complex environment and uses; So this device can overcome the deficiency that receives external interference in the prior art easily, for the detection of object relative position provides stability and reliability preferably.
Because the non-contact capacitive formula liquid level sensor in this device can be adjusted arbitrarily with the installation site of sealing water box, the size that seals the water box simultaneously also can be adjusted, so this device is directed against the applicability that has popularity when the relative position of different objects detects.
This apparatus structure is succinct, uses easily.
