The generation of controller 152 is exported with apart from corresponding level signal, and by adjustment signal to Power Component 151, so that Power Component
151 drive sliding equipment, elevating mechanism 120 to move, and the position of detection zone is adjusted to realize automatically.
For example, the sliding block in Power Component 151 and sliding equipment is sequentially connected, which be can be, but unlimited
It is used to provide the component of mobile power for sliding block in cylinder, hydraulic cylinder, linear motor etc..When Power Component 151 is in lasting reception
When to high level signal, band movable slider is turned left sliding, and Power Component 151 is when persistently receiving low level signal, with movable slider
It turns right movement, when Power Component 151 does not receive level signal, stop motion.Controller 152 can according to it is determining it is practical away from
From generating corresponding level signal.For example, controller 152 can if the actual range is identified with the mark of left/right movement in advance
Corresponding level signal is generated with the mark moved according to left/right.Specifically, for example, actual range is identified with left movement in advance
Mark, also mean that and need to drive sliding block in sliding equipment toward left movement, then controller 152 just generates high level letter
Number, so that Power Component 151 is when receiving high level signal, band movable slider is turned left movement.Alternatively, actual range identifies in advance
Have the mark of right movement, also mean that and need to drive the sliding block in sliding equipment to turn right movement, then controller 152 just generate it is low
Level signal, so that Power Component 151 is when receiving low level signal, band movable slider is turned right movement.
Certainly, Power Component 151 drives the level signal of sliding block side-to-side movement to be also possible to be different from above-mentioned level letter
Number, for example, when Power Component 151 is when persistently receiving low level signal, band movable slider is turned left sliding, and Power Component 151 exists
When persistently receiving high level signal, band movable slider is turned right movement, when Power Component 151 does not receive level signal, stops transporting

The spatial position of part, and make laser irradiation in the corresponding detection zone of laser detection component.
In the present embodiment, Power Component 151 passes through the spatial position for adjusting laser detection component, so that laser irradiation exists
Realization principle in detection zone, can be such that
Inductive component 153 can sense in real time laser irradiation on laser detection component position and detection zone in preset
The distance between mark point, when the distance is less than above-mentioned pre-determined distance value, controller 152 is generated for stopping Power Component
The control signal of 151 movements, Power Component 151 is when receiving the control signal, stop motion, to may make detection zone
The just stop motion when being moved to the position that actual needs reaches, so that laser can be radiated in the detection zone.
Alternatively, laser detector 100 can also include driving position to adjust component movement for measuring Power Component 151
Distance range finder module 154, which can connect with controller 152, for the distance of measurement to be sent to control
Device 152 processed.The range finder module 154 includes but is not limited to that displacement sensor, laser range finder, grating scale etc. can measure distance
Module.Controller 152 is that the distance value that inductive component 153 initially senses (is filling in the distance for receiving the measurement of range finder module 154
When setting starting, inductive component 153 detects before Power Component 151 does not move position of the laser irradiation on laser detection component with
The distance between preset mark point in detection zone) when, generate the control signal for stopping the movement of Power Component 151, power
Component 151 is when receiving the control signal, stop motion, so that detection zone may make to be moved to the position that actual needs reaches
Just stop motion when setting, so that laser can be radiated in the detection zone.
Specifically, range finder module 154 can be set on sliding rail 111 or sliding block, and range finder module 154 can detecte power packages
The distance value that part 151 drives laser detection component to move on sliding rail 111.Another range finder module 154 can be set to be examined in laser
It surveys on component, can be used for detecting height/distance that laser detection component rises or falls.
Understandably, the first distance value that inductive component 153 senses is position of the laser irradiation on laser detection component
With the distance between preset mark point in detection zone.Usually namely Power Component 151 needs to drive position first distance value
Adjust the mobile distance of component.(i.e. controller 152 is according to induction moving direction has been determined through the above way for controller 152
Component 153 send low and high level determine moving direction) after, then control Power Component 151 drive position adjust component movement with
First distance is worth identical distance, can be so that detection zone is moved to the position that actual needs reaches.When range finder module 154
When detecting that laser detector 100 moves first distance, controller 152 just controls 151 stop motion of Power Component, thus
So that detection zone is moved to the position that actual needs reaches, so that laser can be radiated in the detection zone, with complete
At the detection of 200 output powers of testing laser device/hot spot.
As an alternative embodiment, laser detection control method can also include: that controller 152 receives laser inspection
The parameter of component acquisition is surveyed, and judges whether parameter meets preset condition.When parameter is unsatisfactory for preset condition, controller 152
Alarm signal is generated, and alarm signal is exported to alarm module 155.Alarm module 155 can receive report from controller 152
Alert signal, and corresponding warning note is issued according to the alarm signal, in order to which whether operator judges testing laser device 200
Qualification, for example, if alarm module 155 has issued warning note, then the testing laser device 200 is just substandard product.It is based on
This, can be convenient operator by alert notice and determine whether testing laser device 200 is qualified.
Wherein, preset condition can be configured according to the actual situation.For example, controller 152 can be set and laser function
The corresponding power bracket of rate meter 141, when detecting that testing laser device 200 exports the power of laser not in the power bracket,
Controller 152 is just generated for indicating the underproof alarm signal of power, so that the sending of alarm module 155 is unqualified about power
