The working principle of the invention is: present invention employs a common miniature microswitches to open as the starting of circuit
It closes, while being also the power supply switch of circuit.This switch (electricity in the open state always in the case where saw blade is in non-rotating state
Road open circuit), only after saw blade continues to rotate with certain speed, microswitch is pressed into connection circuit using centrifugal force, makes electricity
Road powers and works.The unique distinction of this method is that the cantilever style button that microswitch is utilized has certain quality, works as quilt
Generated centrifugal force (centripetal force is equal in magnitude contrary) is enough to overcome the bullet of microswitch after rotating to certain revolving speed
Property power, press push button connect circuit.
After connecting the power supply of circuit, microcontroller is started to work, and completes temperature monitoring by internal program, according to
Set temperature range, start-up temperature status indicator lamp shown according to different color and frequency, and is informed with this
Saw blade this moment possessed by state of temperature.For the continuation of the journey working time of the circuit under limited battery capacity, microprocessor is adopted
With intermittent operation mode design.As soon as after basic principle is every progress time temperature detection and provides state instruction, stopping fortune
Row a period of time (8-10 seconds or so), make micro process and entire circuit in a dormant state, and after scheduled dormancy time certainly
It is dynamic to be again started up work, repeatedly.
Power supply uses two pieces of 3 volts of lithium battery series-feds.Circuit can operating voltage range be 3-6 volt.Battery for

Design can guarantee the operation stored in a warehouse for a long time with serialization.
Programming interface (ICSP): the port can will be used under the programs such as temperature monitoring for being programmed to microprocessor
It is downloaded in microprocessor.The record of the sequence number of product and operation can also be write as and read.
Temperature monitoring is realized using micro process and temperature sensor, and microprocessor is under set process control, week
The temperature information of saw blade is acquired to phase property, and according to the different mode lightening LED lamp of the temperature range of variable journey.Specifically
One of ignition mode is following: less than and 40 degrees Celsius, the LED of periodic points sapphirine；It is Celsius less than 60 greater than 40 degrees Celsius
Degree, periodic points bright green LED；Greater than 60 degrees Celsius, less than 80 degrees Celsius, periodic points sapphirine and green LED；
Greater than 80 degrees Celsius, less than 100 degrees Celsius, periodic points shiny red and blue led；Greater than 100 degrees Celsius, taken the photograph less than 120
Family name's degree, periodic points shiny red and green LED；Greater than 120 degrees Celsius, periodic points shiny red LED；It is taken the photograph greater than 140
Family name's degree, duration light red LED.
