Fig. 6 be it is shown according to an exemplary embodiment it is a kind of be subjected to displacement applied to steel coil transportation process it is on-line automatic
The displacement detecting schematic diagram of detection device.The present apparatus is mounted on the inside of longitudinal coil of strip, and coil of strip is mobile to drive the present apparatus mobile, rubber
Ball rolls therewith, and ball rolls the grating wheel that horizontal and vertical directions is in charge of in friction again, driving grating wheel rotation, by steel
The Kinematic Decomposition of volume in the plane is movement both horizontally and vertically.
As shown in fig. 7, being horizontally and vertically respectively equipped with grating wheel, grating wheel wheel edge is lattice-shaped, grating wheel
Two sides are infraluminescence component and infrared receiver component respectively.When normal work, the movement of coil of strip is decomposed into horizontal and vertical light
The rotation of grid wheel different directions and revolving speed, the infrared radiation that the grid cycle of grating wheel blocks the sending of infraluminescence component are arrived
The electric pulse of the output end of the first pipe and second pipe of receiving unit, first pipe and second pipe passes to the control chip of main control module, due to first
There are phase differences for pipe and the electric pulse of second pipe output, learn the rotation of grating wheel by judging the conducting order of first pipe and second pipe
Direction, to judge the direction of displacement of coil of strip, electric pulse is as shown in figure 8, a figure is the electric arteries and veins of horizontal direction infrared receiver component
Punching, b figure is the electric pulse of vertical direction infrared receiver component.
Along that can be evenly distributed 18 to 36 gratings, by changing the gratings strips number of grating wheel, position can be changed in grating wheel wheel
The minimum scale of shift measurement, as the gratings strips number of grating wheel increases, the minimum scale of displacement measurement is gradually reduced, but power consumption
Increase, the item number of grating wheel can be designed as the case may be in practical applications.The present invention is designed as 18 gratings, i.e. electric pulse
A cycle represent grating wheel and have rotated 20 degree, the arc length according to geometrical relationship rotation is 20 Π R/180, and wherein R is grating

Change key, the GPRS module is connect with host computer.
As shown in figure 11, the circuit design of main control module is on the basis of fully considering coil of strip real-time displacement monitoring, by mould
Quasi- circuit is combined with the advantage of high performance digital signal controller, designs low cost, intelligence, the circuit easily promoted.
Power module uses 3.7V battery and 12V battery, and 3.7V power supply is powered to CPU, and 12V power supply switchs to 5V by conversion circuit
Power supply, to GPRS module and infrared emission component, infrared receiver component, warning lamp power supply.Electric quantity of power supply monitoring modular by pair
The monitoring to electric quantity of power supply is realized in the measurement of supply voltage, and the supply voltage of measurement is compared by CPU with the threshold value of setting, when
When the corresponding electricity of supply voltage is greater than the 50% of full electricity, CPU control flashing in warning lamp 10 seconds is primary, when supply voltage is corresponding
When electricity is greater than completely electric 25%, CPU controls flashing in warning lamp 5 seconds once, when the corresponding electricity of supply voltage is less than completely electricity
When 25%, it is primary that CPU controls flashing in warning lamp 1 second.CPU has 2 kinds of working methods: low-power consumption standby mode and operating mode, low function
It consumes under standby mode, CPU enters low-power consumption mode, closes most of function, power supply is not powered to GPRS module, when CPU's
P1.4 pin triggers external interrupt when detecting rising edge signal, wake up CPU, power supply is powered to GPRS module, into Working mould
Formula.
Specific installation process of the invention and the course of work:
1, power button is pressed, power supply gives coil of strip displacement on-Line Monitor Device (the hereinafter referred to as present apparatus) power supply；
2, installation personnel records the number of each compartment installation present apparatus, is input to host computer after summarizing, it is possible to use encoder
The present apparatus is encoded, the present apparatus number in each compartment is input to the present apparatus, host computer is sent to by GPRS；
3, the present apparatus is placed on the inside of placed longitudinally coil of strip, adjusts the position of the present apparatus, keep the present apparatus and mounting plane
It is horizontal；
4, one smaller angle of rotary motion bar makes push rod and the clamping of coil of strip inner wall, extracts transmission long axis, three-dimensional cam self-locking dress
It sets and to be formed self-locking, whole device is installed；
5, initialization key is pressed, CPU draws coordinate diagram, be sent to by GPRS using the initial position of the present apparatus as origin
Host computer subsequently enters low-power consumption standby mode；
If 6, coil of strip is mobile, triggering external interrupt enters operating mode, and the present apparatus sends the coil of strip displacement of measurement by GPRS
To host computer, sounded an alarm if displacement is more than predetermined threshold, if displacement is less than predetermined threshold, and in long-time
It is displaced unchanged, the present apparatus is again introduced into low-power consumption standby mode.
The real-time prison of coil of strip displacement can be realized by a device being installed on the inside of placed longitudinally coil of strip in the present embodiment
It surveys；Cost budgeting is as shown in figure 12, during routine use, since main control module is in chassis interior, and the weather such as blow, rain
Reason will not influence main control module work, periodically tears machine open and removes dust, with extremely low cost, improve coil of strip daily management and
The degree of automation of transportational process reduces steel industry cost of labor, obtains bigger profit.
