In one embodiment of the utility model, range finder module 2 is HC-SR04 ultrasonic distance measuring modules, this module can provide
The contactless distance sensing function of 2cm-400cm, including ultrasonic transmitter, receiver and control circuit.Operation principle：It adopts
Ranging is triggered with I/O mouthfuls of TRIG, the square wave of 8 40Khz is sent automatically at least high level signal of 10us, module, it is automatic to examine
Whether survey has signal return, and if there is signal passes back through one high level of I/O mouthfuls of output, high level lasting time is exactly from hair
It is mapped to the time of return.Measuring distance=(the high level time * velocities of sound (340M/S))/2, System Working Principle is as follows：Monolithic
The P1.0 mouth output frequencies of machine are the square-wave signal wave signal of 40kHz, and ultrasonic transmitter is driven after power amplification, is allowed to send out
The super formula for going out same frequency carries out sound wave position number, and at the same time counter starts timing.Ultrasonic signal meets barrier reflection and reflection
To ultrasonic receiver.It obtains being effectively formed interrupt signal after being put into processing and shaping pulse, is sent into the INTO of microcontroller
Mouthful, make microcontroller INTO generate interruption, counter stop timing, can be obtained by this way ultrasonic wave from be emitted to reception when
Between be spaced AP.Range measurement principle is put by ultrasound to know, the distance between Ben Che and barrier d propagation of ultrasonic wave for d=v*AU2
Speed V is related with environment temperature 1, and the relationship between them is:- 331.45+0.611, when the numerical value of d is more than to pacify as defined in system
When full distance size, start caution system.

Counter, 4 external interrupts, one 7 vector, 4 grades of interrupt structures (5 vectorial 2 grades of interrupt structures of compatible tradition 51), full duplex
Serial port；In addition, STC89C52 can be down to the operation of 0Hz static logics, support 2 kinds of softwares that energy-saving mode may be selected.In idle mould
Under formula, CPU is stopped, and RAM, timer/counter, serial ports, interruption is allowed to work on；Under power down protection mode, RAM
Content is saved, and oscillator is frozen, all work of microcontroller stop, until next interruption or hardware reset.
Using the timer 1 inside the timer inside microcontroller, working method 0 and external interrupt 0, when external interrupt 0
After receiving the signal that ultrasonic wave module is sent, because external interrupt 0 is low level triggering, external interrupt 0 is just by height before
Level becomes low level, then timer begins to work at this time, controls laser head with the frequency scintillation of interval 1S；It is wherein fixed
When device operation principle：Timer inside microcontroller is to be arranged to timer also by counter to switch different operating modes
It is counter, is exactly timer if being set as 0 pattern if it is exactly counter to be arranged to 1 pattern, is set as fixed at this time
When device pattern, it is to count that (1 machine cycle is equal to 12 cycles of oscillation, i.e. count frequency to the internal machine cycle to add 1 counter
It is the 1/12 of crystal oscillator frequency).It is exactly timing t that count value N, which is multiplied by machine cycle T,.
