After horizontal distance, range information is transmitted to by Cloud Server by radio receiving transmitting module, Cloud Server handles the information transmission request
And range information is sent to mobile client, i.e. operator's mobile phone, operator is according to the horizontal distance measurement result being transferred to
Horizontal distance between device and monitored object is adjusted, until meeting working stamndard requirement.
3. operator inputs desired height in the software interface of mobile client, which can be successively through cloud
Server, radio receiving transmitting module reach central control module.Meanwhile vertical distance sensor will be sensed by laser ranging
Signal be transmitted to central control module after A/D converter is converted, signal processing is range information and added by central control module
After upper vertical distance sensor and the vertical range at microphone center, compared with the range information that mobile client transmits,
Compare two range informations it is inconsistent when, by the operating of stepper motor to change lifting support height.
4. mobile client assigns the finger of noise monitoring starting after measuring horizontal distance and vertical range meets the requirements
It enables, which is transmitted to central control module through Cloud Server and radio receiving transmitting module, and central control module can control microphone
The sound pressure signal monitored is converted into electric signal by starting, microphone, and signal is through decaying-amplifier, to improve signal-to-noise ratio, then
Output signal is transmitted to filter, to carry out spectrum overlapping to signal, is then sent the signal through weighted to wave detector to examine
Useful signal out, and this signal is sent to central control module, central control module handles received useful signal
It is converted into sound level information, and sound level information is sent to radio receiving transmitting module, sound level information is uploaded to cloud and taken by radio receiving transmitting module
Business device, Cloud Server handle the information transmission request and sound level information are sent to mobile client, in addition, secondary sound level monitoring
Information can also be stored into the memory space through Cloud Server, and the mobile client client for possessing permission can realize monitoring information
Cloud downloading.
