Modern

is

profound

on

people's

lives,

to

people's

life

and

working

way

to

bring

convenience

to

our

daily

lives,

all

aspects

of

electronic

in

the

shadow,

single

as

one

of

the

most

important

applications,

in

many

ways

it

has

the

inestimable

role.

Intelligent

control

is

a

single

chip,

intelligent

control

of

applications and prospects are very broad, the use of modern technology tools to

develop

an

intelligent,

relatively

complete

functional

software

to

achieve

intelligent control system has become an imminent task. Especially in today with

MCU

based

intelligent

control

technology

in

the

era,

to

establish

their

own

practical control system has a far- reaching significance so well on the subject later

more fully understanding of SCM are of great help to.

The so-called intelligent monitoring technology is that:

processing of the information of the monitored device

one's field of vision, and intelligent monitoring equipment can be regarded as the

human

brain.

Intelligent

monitoring

with

the

aid

of

computer

data

processing

capacity

of

the

powerful,

to

get

information

in

the

mass

data

to

carry

on

the

analysis,

some

filtering

of

irrelevant

information,

only

provide

some

key

information. Intelligent control to digital, intelligent basis, timely detection system

in the abnormal condition, and can be the fastest and best way to sound the alarm

and

provide

useful

information,

which

can

more

effectively

assist

the

security

personnel to deal with the crisis, and minimize the damage and loss, it has great

practical

significance,

some

risk

homework,

or

artificial

unable

to

complete

the

operation, can be used to realize intelligent device, which solves a lot of artificial

can not solve the problem, I think, with the development of the society, intelligent

load in all aspects of social life play an important reuse.

Single

chip

microcomputer

as

the

core

of

control

and

monitoring

systems,

the

system structure, design thought, design method and the traditional control system

has essential distinction. In the traditional control or monitoring system, control or

monitoring

parameters

of

circuit,

through

the

mechanical

device

directly

to

the

monitored parameters to regulate and control, in the single-chip microcomputer as

the core of the control system, the control parameters and controlled parameters are

not directly change, but the control parameter is transformed into a digital signal

input to the microcontroller, the microcontroller according to its output signal to

control

the

controlled

object,

as

intelligent

load

monitoring

test,

is

the

use

of

single-chip

I

of

relay

control,

then

the

load

to

control

or

monitor,

thus

similar

to

any

one

single

chip

control

system

structure,

often

simplified to input part, an output part and an electronic control unit ( ECU )

Intelligent

as

each

module to provide normal working voltage, another set of ADC module work limit

, if the input voltage is greater than 5V

, it can not work normally ( but

the

provided

for

so

it

at

and

then

through

plays the role of power supply. Signal to the analog-to-digital conversion module,

In the intelligent load monitoring system, using the monolithic integrated circuit to
