Description
Technical field
This patent designs a kind of contactless linear valve displacement detector, especially a kind of for YE and to realize the noncontact displacement monitor of real-time valve collection.
Background technology
Execution link of the YE as technological process and control theory in systems in practice, its reliability decides the safety and benefit of industrial process.YE is due to the popularization of electric power networks, the lifting of itself explosion-proof capabilities, integrated can especially control, diagnose, display function in one, it has been an important executing agency in industrial automation system, has been widely used in the fields such as oil, chemical industry, water power, ship, metallurgy, the energy, light textile, food, medicine, urban water supply and sewerage.YE is a kind of important Detection ＆ Controling equipment for realizing energy saving, environmental protection, recycling economy.Pneumatic actuator can simply realize quick linear circulating motion, and simple structure, maintenance is convenient, while can be used in various harsh environments, if any the operating mode of requirement of explosion proof, many dust or humidity.And the valve displacement detection of pneumatic actuator is a key link, because the whether accurate of displacement detecting directly influences production process, product quality and energy-saving consumption-reducing.
At present, the displacement detector of YE is typically used, and one is that, using the position output of potentiometer or other analogue measurement element testing actuators, the position feed back signal by obtaining potentiometer after AD conversion, process is complicated, and speed is low, low precision；Two be using photoelectric figure technology, using system power supply hair that be, the station acquisition after system power failure just cannot realize power down, and photoelectric type position harvester is higher to operating environment requirements, easily by dust the problems such as influenceed；Three is the control mode using stand-by power supply, but displacement acquisition device power consumption is big, and frequent row changes stand-by power supply, is increased after sale and cost of serving.
The content of the invention
This patent provides a kind of linear valve displacement detector simple to operate, low in energy consumption, and can real-time monitoring valve displacement device.
A kind of contactless linear valve displacement detector, it is characterised in that including：
Welding assist side（4）On Hall sensor（5）；
The magnetic stripe being connected with valve（1）；
Magnetic is transmitted to the magnetic conductor of Hall sensor（2）.
The Hall sensor sensor（5）It is Hall switch magnetic induction sensor, can be with the change of induced field, and output digit signals.
The magnetic stripe is by multiple magnet（11）It is laterally uniform to form, the position of valve event can be known by the size in magnetic field, and one is directly connected with valve universal driving shaft.
Due to magnetic conductor（2）Positioned at magnetic field generation part（Magnetic stripe（11））With Hall sensor（5）Between, therefore it is required that the detectable magnetic field of magnetic conductor.Profile is just as " n " type, upper end and Hall sensor（5）Contact, lower end and magnetic stripe（1）Contact.
The Hall sensor sensor that this patent is used（5）There is, output voltage change wide to magnetic-field-sensitive, simple structure, small volume, frequency response greatly and long service life, using Hall sensor sensor photoelectric sensor can be overcome easily affected with dust, the defect higher to application environmental requirement.
The contactless linear valve displacement detector of this patent realizes contactless displacement acquisition using magnetoelectric induction technology, overcomes potentiometer or other analogue measurement element testings perform the position output procedure complexity of phase, and speed is low, the problem of low precision；The position output procedure for also overcoming potentiometer or other analogue measurement elements monitoring actuator is complicated, and speed is low, the problem of low precision；Also overcoming Traditional photovoltaic formula non-contacting position harvester cannot continue to gather positional information after system power failure, it is impossible to realize real-time.

Referring to accompanying drawing, a kind of contactless linear valve displacement detector of this patent includes Hall sensor（5）, magnetic stripe（1）With magnetic magnetic conductor（2）Three parts constitute.
As shown in Figure 1, magnetic stripe（1）A side wider is by multiple circle small magnets（11）It is laterally uniform, magnetic stripe（1）A narrower side has two small sircle holes, and magnetic stripe is connected with valve universal driving shaft using two circular holes.
As shown in Figure 2, magnetic conductor（2）It is to be made up of the aluminium flake of two " L " types, it is fixed in a specific plastic casing, a side and Hall sensor（5）Sensing, the other end and magnetic stripe（1）Sensing.
As shown in Figure 3, the overall structure of contactless linear valve displacement detector can be learnt.
Hall sensor（5）Positioned at circuit board（4）On, using contact pin by circuit board（4）It is fixed on circuit board（3）On.
Signal processing circuit is integrated in circuit board（3）On, with Hall sensor（5）Circuit board（4）Circuit board is fixed on by contact pin（3）On, while making to produce gap between the two, make Hall sensor（5）Form the magnetic field of fixing intensity.
The operation principle of this patent：When valve is rotated, universal driving shaft can drive magnetic stripe（1）Move up and down together, magnetic stripe（1）On have magnet（11）Place can produce magnetic field, magnetic conductor（2）Magnetic field is sensed, magnetic field is sent to Hall sensor（5）, so that Hall sensor（5）The pulse signal of generation rule, and send to signal processing circuit（In not drawing）.Signal processing circuit（In not drawing）By processing the pulse signal, the position and direction of valve are judged.Displacement detecting when being operated manually after the control circuit realiration of power supply system power failure, it is ensured that the real-time of displacement information.
Signal processing circuit（In not drawing）In single-chip microcomputer, Hall sensor of the governor circuit by signal MSP430F20120（5）Composition.Hall sensor（5）Output end access input P1.0, P1.1 button of single-chip microcomputer, single-chip microcomputer communicated by spi bus mode with the main control CPU of YE master control borad.
Power control circuit（In not drawing）In, without setting up power supply switching control button, using MOSFET FETs（Switched equivalent to switching）Realize the automatic switchover that power supply is powered with system power supply.When system power supply, FET is by displacement monitoring control circuit（In not drawing）Powered by SYS-POW-OUT parts, i.e., by system power supply；During system power failure, FET connection 3.6V batteries are powered by battery；The power consumption of Hall sensor is very big, using MOSFET FETs（Equivalent to output control switch）Grid be connected with the P2.0 mouthfuls of EN-HELL of single-chip microcomputer MSP430F20120, realize scan-type power supply control to Hall sensor by software, reduce the overall power of system, make that displacement detector is low in energy consumption to put several mA.Can also be arranged as required to the diode of rectification in power control circuit, and for test or partial pressure the element such as resistance.
