4.4 The structure of the single-chip tool monitoring
system
The single-chip tool monitoring system can be divided
into sensor circuit,signal amplified circuit,filter circuit,
A/D circuit,I/O circuit,display signal circuit,communication
circuit,CPU circuit,electric current circuit,and
software programs.The system structure is shown in
Fig.1.The hardware circuit of the single-chip tool
monitor is shown in Fig.2.The function of each device
is described as follows.
4.4.1 The flowchart of the circuit signal
The signal of turning force detected by strain gauge is
line-shielded and transmitted to the pre-amplifier
(AD624) to amplify the signal 200-fold,then passed to
the differential amplifier to remove the offset voltage and
amplify 100-fold,and subsequently passed to the 45 Hz
LPF to filter the noise signal of high frequencies.At this
point,the signal is separated into 2 parts.One is sent to
LM3914 for the instant signal display monitor,the other
is sent to AD1674 (A/D converter) to convert the analog
signal to a 12-bit digital signal.Under normal circumstances,
the 8051 cannot process 12-bit data because it is
an 8-bit microprocessor.The 12-bit signal needs to be
