Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment in this utility model.
Fig. 2 is the electronic device connection diagram of an embodiment in this utility model.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, each embodiment of the present utility model is explained in detail.
As it is shown in figure 1, the space 11 that the metal dimension shape detecting apparatus that this utility model provides is mutually penetrating before and after being combined into gate main body 10 by base 9, the transport band 8 of belt feeder (one of nonmetal conveyer belt) is through this space 11.Base being mounted with, tachogenerator 1 (one of rate-measuring device) is used for measuring belt transmission speed.Several three axles magnetometers are installed in the left and right sides in space 11, respectively 2,3,6, the positions such as 7, upper and lower installs controllable electromagnetic coil 4,12, producing parallel uniform magnetic field, it is also possible to three axle magnetometers are located at the upper and lower in space 11, controllable electromagnetic coil is installed in the left and right sides.Electronic section is by control unit, sensing module, power module, Electromagnetic Control module and communication module composition.It is also preferred that the left in this utility model, multiple three axle magnetometers are uniformly distributed on this space 11.
Sensing module is made up of N number of three axle magnetometers, is connected with control unit by spi bus, and three axle magnetometers are for detecting size and the direction of magnetic flux on tri-axis of orientations of XYZ in space.Control unit is made up of high performance DSP, and Electromagnetic Control module is made up of IGBT and coil, and DSP directly controls IGBT module by PWM I/O port, makes coil lead to super-high-current when needing, and makes interior volume produce parallel uniform magnetic field.Tachogenerator is connected to the sequential of DSP and catches port, transports the speed of band by measuring signal change measure of time belt feeder.Communication module is made up of with RS485 module signal output, and DSP is respectively adopted GPIO with UART port and is attached thereto.Signal output uses relay mode externally to produce digital quantity signal, and RS485 interface uses digital communication mode to be connected with external system, makes user pass through upper computer software and realizes the setting to device parameter, including the size of metallic foreign body, type of alarm etc..In addition, a mechanical arm is may be equipped with in this device, the metal size, the shape that comprise in device detects sandstone aggregate exceed preset value, while control alarm unit sends alarm, mechanical arm can also be controlled taken off from conveyer belt by corresponding sandstone aggregate, with anti-error, this sandstone aggregate is added in pulverizer, cause pulverizer fault.
Whole equipment workflow is as follows, first starting device, and first each three axles magnetometer is initialized by DSP, starts PWM control IGBT and makes the solenoid of equipment upper and lower motivate a stable static parallel uniform magnetic field.DSP gathers three axle magnetometer data, forms the magnetic line of force feature of this point, uses the method for compression sampling that the space in space 11 is divided into multiple equal-sized area of space, concrete, sets up electric field cloud atlas
In formula, φM,NBe three axle magnetometer measures in M network to be positioned in N network simulation magnetic flux value.It is also preferred that the left there are N number of three axle magnetometers can be divided into 6N to 8N sub spaces region.Magnetic body simulation method is used to extrapolate remaining each space magnetic flux distributions feature with each three axles magnetometer basic point.Finally, each spatial integration getting up to be formed device space internal magnetic field cloud atlas, the magnetic field cloud atlas in the device space is rebuild by equipment the most in real time, and carries out with the magnetic field cloud atlas set up when initializing in real time.In the process, therefore, to assure that there is no any metallic foreign body in space, otherwise can cause error to detecting accuracy rate during follow-up operation.When finding that metallic foreign body size exceedes restriction threshold value, signal output interface will export break-make number signal.
After initialization completes, start belt conveyor.It is nonmetallic substance owing to transporting band, during motion, the magnetic field in the device space will not be produced any impact.When transporting the upper metallic foreign body of band and entering the device space, the magnetic field in space will be affected by metallic foreign body and be changed.At this moment the space internal magnetic field cloud atlas that equipment is rebuild will change, and equipment is by new cloud atlas and the initial cloud atlas comparison of foundation in initialization procedure.Due to the existence of metallic foreign body, the magnetic flux in target area can be made to change, the area of space of these change of flux of labelling is also combined, and forms shape and the size of target acquisition object.Concrete, the image alignment algorithm of application maturation by extracting section different in Background out, sets up body form sideline, forms the profile of metallic foreign body, and by the size of this profile measurement profile, shape.Detecting object shape and size accuracy play the most divided area of space size, the shape of the least detecting object of area of space is the most accurate with size, and partition space area size is by a region quantity and space size can be divided to determine, General Spatial size is to be correlated with according to on-the-spot actual belt conveyor size, and the quantity of a region quantity and three axle magnetometers can be divided to be correlated with.
Owing to can not infinitely increase by three axle magnetometer quantity in real system to promote cloud atlas precision in reconstruction attractor, this utility model has been additionally arranged at the bottom tachogenerator at equipment, can measure transport tape speed.System uses frequency to make metallic foreign body when by space according to the adjustment transporting tape speed, sets up 2N sampled data.Owing to being parallel magnetic field in space, metallic foreign body when space is moved to magnetic fields.The change transitions in magnetic field now can become metallic foreign body is static, parallel magnetic field is constant, but three axle magnetometers are moving.By three axle magnetometer samples when gathering are converted into the data that multiple three axle magnetometers are sampled in different spatial, making three axle magnetometer quantity " be doubled and redoubled ", in space, Spacial domain decomposition is the finest, and result of detection is the most accurate.
The respective embodiments described above are to realize specific embodiment of the utility model, it will be understood by those skilled in the art that and in actual applications, can to it, various changes can be made in the form and details, without departing from spirit and scope of the present utility model.
