Detailed description of the invention
In order to keep the purpose of the present invention, technical scheme and beneficial effects clearer, the present invention provides following attached drawing and carries out
Illustrate:
Fig. 1 is schematic structural view of the invention；
Fig. 2 is MCU electrical block diagram in the present invention.
Specific embodiment
Below in conjunction with attached drawing, a preferred embodiment of the present invention will be described in detail.
As shown in Figure 1 and Figure 2, ultrasonic radar monitoring modular is integrated, exports frequency when 1.5 meters barrier occur in front of equipment
Flashing light and 90db alarm；Integrated mcu data acquisition module exports LED when field monitoring instrument data exceeds preset threshold
Warning lamp or alarm.Equipment is installed on by field monitoring instrument, and is powered using instrument power source.
Ultrasonic radar sensor detects in front of equipment output stroboscopic lamp and 90db alarm when barrier occur for 1.5 meters.
The output data of real-time collection site monitoring instrument, after being pre-processed, being parsed to data compared with preset threshold,
Sound-light alarm is exported when beyond preset threshold.
Equipment and field monitoring instrument share power supply, support wide range input.
Equipment volume is small, light-weight, is mountable near monitoring instrument, or pastes and be fixed on instrument casing.
Ultrasonic radar measurement method: with time difference method come ranging, alternatively referred to as bounce technique, i.e., ultrasonic wave connects from being emitted to
Receiving need to reflect by object, so expending twice of time, if distance is D, time T, velocity of sound C, formula is D=(C*T)/2；
When equipment nearby has barrier, ultrasonic wave is met its signal of barrier and is reflected, and calculates equipment and obstacle by above-mentioned formula
Distance between object (such as Construction traffic) triggers warning device if less than 1.5 meters, exports stroboscopic lamp and alarm.
The setting method of threshold values are as follows:
Analyses of Tunnel Wall Rock Stability warning index takes surrouding rock deformation rate υ and deformation s2 index of aggregate-value, when one of them
Warning index reaches threshold value of warning, that is, thinks that Analyses of Tunnel Wall Rock Stability reaches alert status.
Threshold value needs to comprehensively consider engineering geological condition, arrangement and method for construction is determined using the method for Numerical Analysis of The Limit.With regard to tunnel
For road engineering, critical state when wall rock destabilization, surrounding rock stability safety coefficient is 1.0, however for Practical Project, it is
Ensure construction safety, reach the purpose that gives warning in advance, the threshold value of warning of this system can calculate by Numerical Analysis of The Limit and obtain country rock
Safety factor of stability control each surrouding rock deformation rate υ n (n=1,2,3 ...) for excavating step and surrouding rock deformation at 1.2 is accumulative
Value S n (n=1,2,3 ...) inputs early warning system as the forewarning on engineering failure threshold value.
Finally, it is stated that preferred embodiment above is only used to illustrate the technical scheme of the present invention and not to limit it, although logical
It crosses above preferred embodiment the present invention is described in detail, however, those skilled in the art should understand that, can be
Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
