As shown in fig. 13, the magnetic flux of the normal mode wall cross section is Φ ═ B1S1Assuming that the magnetic induction at the die hole is B2, since the total magnetic flux through the die wall is constant, B is2＝B1S1/(S1-S2) Therefore, the leakage flux around the die hole is proportional to the cross-sectional area of the die hole and the magnetic induction of the ring die wall. The main reason influencing the leakage magnetic flux is the die hole, corresponding analysis is carried out, and a corresponding detection means is adopted in a targeted manner to detect the leakage magnetic field, so that the die hole can be positioned.
The hall sensor is a magnetic sensor based on the hall effect principle, and can be used for detecting a magnetic field and changes thereof. The hall voltage output of the sensor is proportional to the strength of the magnetic field across the sensor's sensing element. The principle formula is as follows:
in the formula, VH: a Hall voltage (V);
RH: a Hall coefficient;
i: flowing a sensor sensing element current (A);
t is the thickness (mm) of the sensitive element;
b, magnetic induction intensity (T).
As shown in fig. 7, the electromagnet module 20 on the fixed-bore clearing device 9 generates a uniform steady magnetic field around the hall sensor 21. When the hole pull throughs 9 are set manually to detect the holes, the hall sensors 21 on the hole pull throughs 9 can output different voltages VH according to the difference of the magnetic field intensity on the measured ring die:
when the probe of the hall sensor 21 is over against the non-hole area (ring mold), the electromagnet module 20 is influenced by the magnetic material (ring mold), the magnetic field intensity of the hall sensor 21 can change, then the magnetic induction line density passing through the hall element can change, the magnetic field intensity measured by the hall sensor 21 is different, the leaked magnetic flux is also different, then the voltage VH output by the hall sensor 21 can change, when the probe of the hall sensor 21 is over against the hole, the probe of the hall sensor 21 moves to the hole center from the beginning to the hole center, then moves to the outside of the hole, the output voltage VH of the hall sensor 21 has a maximum value in the process, and the maximum value point is the position of the mold hole. In the implementation process, the Hall sensor 21 detects the die hole, the output voltage VH is transmitted to the AD module through the voltage follower, the data is transmitted to the single chip microcomputer MCU after analog-digital conversion, and the single chip microcomputer MCU processes the data information and transmits the data information to the LCD for display. No matter when the key K1 is pressed, the USB is switched into the serial port and upper computer communication operation mode, or the key K2 is pressed, the wireless and upper computer communication operation mode is entered, the magnetic flux detection, the voltage data processing, the conversion, the information transmission and the LCD display in the process can be operated in the two working condition modes all the time in a circulating mode, and the process is ended until the hole detection and dredging are completed or the interruption occurs. Under the communication operation mode of the USB-to-serial port and the upper computer, the single chip microcomputer MCU always circularly transmits data to the upper computer synchronously through the USB-to-serial port module, receives an upper computer command, and is also stopped until the completion of the dredging of the die hole or the interruption occurs.
As shown in fig. 8-9, the control system is initialized when the control system starts to perform the positioning and dredging of the die hole.

The single chip microcomputer MCU controls the movement of the manipulator to enable the Hall sensor 21 to detect and position the die holes, if no die hole exists (namely the maximum output voltage VH does not exist), whether all the die holes are detected is judged to be finished, if the die holes are detected to be finished, the program is finished, the control system and the manipulator reset, and if the die holes are not detected to be finished, the program returns to continue to detect the die holes; when the die hole (namely the maximum output voltage VH) is detected, the MCU firstly controls the relay module to enable the electromagnet module 20 to be powered on and powered off, and then controls the manipulator to move, so that the counter-magnetic drill bit 22 reaches the detected die hole position, and controls the fourth motor to rotate to dredge the die hole. And after the mold holes are dredged, the buzzer rings to prompt that the mold holes are dredged once, then the program is returned to continue to detect the mold holes until the whole mold holes are dredged, and the control system and the manipulator reset.
As shown in fig. 10 to 12, the VC is used as an upper computer interface in the present invention, and is applied to Microsoft Communications Control controls, button controls, combo box controls, static text controls, list controls, and the like. The main functions of the upper computer software are to set the relevant parameters of the serial port, convert the received data into waveform display, control the gain and conversion rate of the ADS1110, display the ADS1110 conversion value information, store and display the AD conversion data, display the personal information of the user, and control the fourth motor.
The serial port setting module is used for selecting serial port numbers through the two combo box controls and setting serial port baud rates; and the serial port is opened and closed through the two button controls.
The waveform display module realizes the display functions of stopping, starting, emptying and the like of waveform display. Wherein the stopping and starting of the display is accomplished by turning on and off a timer and the clearing of the display is accomplished by initializing the display array to 0.
And the rate gain control module is used for sending a command to the lower computer through a message response function corresponding to the radio button control, and after receiving the command, the lower computer performs write operation on a register of the AD chip according to the preset value to change the gain and the conversion rate of the preamplifier.
The motor module sends two characters of 'g' and 'h' to the lower computer through two radio button controls, and when the 'g' is received, the motor rotates to realize the dredging of the die hole; when the motor stops rotating after receiving the 'h'.
And releasing a button of the lower computer, sending's' to the single chip microcomputer, and after the single chip microcomputer receives the's', enabling the flag0 to be 0, stopping sending data to the upper computer and disconnecting the upper computer.
The implementation of the "show/hide acquisition data" button controls the list control to expand or hide. The list control has two columns, one column displays the item numbers, and the other column displays the currently uploaded AD conversion values. When the list control is expanded and hidden, the picture control needs to be matched for use, and the picture control determines the range of the list control. The core function is the SetWindowPos () function that changes the size, position, and Z-order of a child window, pop-up window, or top-level window.
And the 'clear acquisition data' button controls the list control and clears the AD value displayed by the list control. The button is realized through an m _ List, DeleteAllItems () function statement, and a DeleteAllItems () function is called by an object m _ List generated by a List control to realize zero clearing of all current entries.
The other two STATIC text controls display the conversion value and voltage in real time, namely SetDlgItemText (IDC _ STATIC _ ADSZ, str) and SetDlgItemText (IDC _ STATIC _ HRDY, str2+ "V), waveform display program code, which is embedded in the OnPain () function and is refreshed simultaneously under the action of the OnTimer () function together with the background. Firstly creating a brush, reloading the brush, drawing the value of an m _ dat [ ] array by MoveTo () and LineTo () functions when drawing a waveform, wherein the m _ dat [ ] array is a global variable and stores the number currently received from a serial port.
