Raman spectrum caused by Raman scattering effect of the determinand for exciting light is surveyed to detect and identify substance.It is widely used in liquid
The fields such as body safety check, jewelry detection, explosive detection, poison/drug detection.Wherein, when Raman spectrometer is applied to explosion
When the quick discriminating of object and hazardous chemical.On the one hand require instrument as small and exquisite as possible, light-weight, in order to carry.Separately
The person of user of service is set off an explosion and threatened when on the one hand needing the laser irradiation for preventing Raman spectrometer from sending out to checking matter
Safety.How to realize in practice, which prevents object to be detected from outburst occurs, needs while realizing following two functions：1, it realizes
To detecting the real-time detection of sample；2, it realizes and the remote control of detection process is controlled.It has developed in the prior art portable
The Raman spectrometer of formula, but this Portable Raman spectrometer, in order to realize the miniaturization of instrument, nose cone and camera are all
Positioned at the same end face of instrument and it is fixed and can not stretches or move.And when detecting sample, sample is placed on nose
At cone, the laser irradiation sample that instrument is sent out, the Raman spectrum by detecting sample realizes the discriminating of substance.At this time due to
Nose cone and camera are all located at the same end face of instrument, cause the visual field of camera that can not cover sample, that is, image
Head can not be to taking pictures to sample or video surveillance.In addition, existing Portable Raman spectrometer does not have remote control yet
The function of operation.Specifically, it is existing therefore, how to develop a kind of novel handheld Raman spectrometer, can realize
Detection sample and remote control control, cause to hinder when explosion being effectively prevent surprisingly to occur to staff under real-time video detection
Evil is that those skilled in the art need the direction studied.
Invention content
The present invention provides a kind of handheld Raman spectrometer, can realize to sample to be tested in real-time video monitoring and
Remote control controls, and prevents the explosion surprisingly injury caused by staff, safety greatly improved.
The specific technical solution that it is used is as follows：

Go out the comparison difference of the two；Described control unit is used to read the comparison difference of described image comparing unit output, and is comparing
Difference exports silence signal when being not equal to zero, control spectrometer ontology is stopped；The acousto-optic hint unit is used for
Control unit generates acousto-optic hint signal when exporting silence signal.
By using this technical solution：Control terminal constantly makes the difference the front and back two field pictures of camera shooting.Due to
Sample is static, if not because laser power is excessive and ablation such as leads to burning luminous or produces thick smoke at the abnormal phenomenon,
Then the difference of two field pictures is equal to zero.Burning is caused to shine or produce thick smoke etc. abnormal phenomenon if there is ablation, two field pictures
Difference can significantly be not equal to zero, control unit closes the laser on spectrometer ontology immediately at this time, while opening acousto-optic hint
It reminds staff to detect and danger occurs.
Compared with prior art, the configuration of the present invention is simple, it is easily prepared.It can realize to sample to be tested in real-time video
Monitoring and remote control control prevent the explosion surprisingly injury caused by staff, safety greatly improved.

Fastened by screw is on spectrometer ontology 1；A side of the fixture 21 is equipped with the first sleeve 211 and second sleeve 212；It is described
Speculum 22 is equipped with 3rd sleeve 221 and 4th sleeve 222；The cylinder axis body 23 sequentially runs through the first sleeve 211, third
Sleeve 221,4th sleeve 222 and second sleeve 212.
Wherein, the signal transmission unit includes that the whole network leads to wireless communication module.Spectrometer ontology 1 uses ARM as master
Processor is integrated with the whole network on its circuit main board and leads to wireless data communication module and bluetooth module, carries SIM card interface, branch
Hold movement/unicom 2G, 3G, 4G and the access of telecommunications 4G network high-speeds.USR-G402tf can be selected in wireless data communication module, but not
It is limited to USR-G402tf.Arm processor and SR-G402tf by USB interface communicate the control terminal 3 using mobile phone, PAD,
Any one of PC machine.The control terminal 3 includes image reading unit, image comparing unit, control unit, acousto-optic hint list
Member；Described image reading unit is used to read the picture signal of 1 output of spectrometer ontology with the speed of 10 frame per second；Described image
Comparing unit compares each frame image signal for sequence and calculates separately out the comparison difference of the two two-by-two；Described control unit is used
In the comparison difference for reading the output of described image comparing unit, and silence signal is exported when comparing difference and being not equal to zero,
Control spectrometer ontology 1 is stopped；The acousto-optic hint unit is used to generate when control unit exports silence signal
Acousto-optic hint signal.
In practice, when detected article danger is not too high, i.e. assessment thinks safe distance at 5 ~ 10 meters, that is, permits
Perhaps operating personnel are detected operation and control terminal in 5 ~ 10 meters of article in distance, then can select bluetooth communication, i.e. control eventually
End sends instructions to Raman spectrometer by bluetooth, so that Raman spectrometer detection is detected the Raman spectrum of article, and pass through
Bluetooth sends measure spectrum data and measurement result to control terminal.
And when detected article danger is very high, i.e., when assessment thinks that safe distance is more than 10 meters, control terminal passes through
