Described camera and ultrasonic sensor arrange one group at least respectively, are arranged on right side and/or the rear side of rotary drilling rig.Video information in the rear side of camera Real-time Collection rotary drilling rig and the visual range on right side is also sent to main control chip, the people of the rear side of ultrasonic sensor Real-time Collection rotary drilling rig and the detectable range on right side or the positional distance information of obstruction are also transmitted main control chip, and display over the display.
Described angular transducer is arranged on the rotary motor of rotary drilling rig.In order to detect the anglec of rotation of rotary motor, and angle information is passed to main control chip.When car load is when turning round, main control chip output voltage signal drives relay, and relay adhesive, makes acoustooptic switch obtain electric, send alarm signal.
Described relay is normal-open type relay, and when according to the signal that angular transducer is beamed back, main control chip judges that car load is when turning round, main control chip output voltage signal drives relay adhesive, audible-visual annunciator is obtained electric, sends alarm signal.
The beneficial effects of the utility model are:
(1) under the commander not needing ground staff, utilize camera and ultrasonic sensor to transfer back to the positional distance information of video information on display and correspondence, the operating personnel of rotary drilling rig can the manipulation operation of safe ready.
(2) buzzer can detect when obstruction is crossed near at ultrasonic sensor and give the alarm to operating personnel, improves safety guarantee.
(3) automatically can send sound and light alarm when achieving Operation of Rotary Pile Drill, when rotary drilling rig is static, sound and light alarm stops, and display can synchronization monitoring revolution warning message simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model theory diagram.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the utility model is described further.
Operation of Rotary Pile Drill monitoring early-warning system comprises main control chip, angular transducer, relay, audible-visual annunciator, camera, ultrasonic sensor, display and buzzer, angular transducer, camera, ultrasonic sensor, display are connected with main control chip respectively with buzzer, and audible-visual annunciator connects main control chip by relay.
Embodiment one:
Camera and ultrasonic sensor arrange two groups respectively, are arranged on right side and the rear side of rotary drilling rig.Video information in the rear side of camera Real-time Collection rotary drilling rig and the visual range on right side is also sent to main control chip; Grow the rear side of distance ultrasonic sensor Real-time Collection rotary drilling rig and the people of detectable range on right side or the positional distance information of obstruction and be sent to main control chip; Main control chip judges positional distance information whether lower than the safe distance threshold value of 0.5 ~ 1 meter that presets, if lower than, then send signal to buzzer, buzzer warning, main control chip is sent to simultaneous display on display screen by after video information and the superposition of positional distance synchronizing information, namely while real-time display video picture, also demonstrate man-made calamity obstruction in video pictures, from the real-time distance of rotary drilling rig, check for operator.
Angular transducer is in order to detect the anglec of rotation of spun digger rotary motor, and when rotary motor moves, angular transducer sends the indefinite square-wave signal of difference 90 ° of frequencies, and this two paths of signals is designated as A phase and B phase.Programmable logic controller receives the square-wave signal that angular transducer sends, and carries out program process.Judged the rotating of rotary motor by the phase difference of two-way square wave, concrete mode is, when the leading B phase of A phase 90 °, car load turns to as clockwise, and when the leading A phase of B phase 90 °, car load turns to as counterclockwise.Can be calculated the angle of revolution of motor by the frequency of two-way square-wave signal, then divided by rotating ratio, just obtain the angle of revolution of car load, specific formula for calculation is: when this value is greater than 360 degree, deduct the integral multiple of 360, obtain the value of a 0-360 degree.
Setting timer, timing cycle is 0.5 second, in each timer period, angle of revolution angle value is assigned to memory, what namely deposit in memory is angle of revolution before 0.5 second, the value in real-time angle of revolution and memory is compared, when the absolute value of its difference is greater than 5, then think that car load is in revolution, now programmable logic controller output voltage signal drives relay, relay adhesive, and its constant open contact is closed, acoustooptic switch obtains electric, sends alarm signal.
During car load revolution, main control chip synchronously sends warning message to display, after display receives controller signals, shows red revolution warning lamp over the display.
Embodiment two:
Camera is arranged on the rear side of rotary drilling rig, and ultrasonic sensor is arranged on the right side of rotary drilling rig.Video information in visual range on rear side of camera Real-time Collection rotary drilling rig is also sent to main control chip; The people of detectable range on the right side of long distance ultrasonic sensor Real-time Collection rotary drilling rig or the positional distance information of obstruction are also sent to main control chip.Main control chip judges positional distance information whether lower than the safe distance threshold value of 0.5 ~ 1 meter that presets, if lower than, then send signal to buzzer, buzzer warning, video information is sent to simultaneous display on display screen by main control chip, checks for operator.All the other are with embodiment one.
Embodiment three:
Camera is arranged on the right side of rotary drilling rig, and ultrasonic sensor is arranged on the rear side of rotary drilling rig.Video information in visual range on the right side of camera Real-time Collection rotary drilling rig is also sent to main control chip; The people of detectable range on rear side of long distance ultrasonic sensor Real-time Collection rotary drilling rig or the positional distance information of obstruction are also sent to main control chip.Main control chip judges positional distance information whether lower than the safe distance threshold value of 0.5 ~ 1 meter that presets, if lower than, then send signal to buzzer, buzzer warning, video information is sent to simultaneous display on display screen by main control chip, checks for operator.All the other are with embodiment one.
By reference to the accompanying drawings embodiment of the present utility model is elaborated above, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, the various changes made under the prerequisite not departing from the utility model aim, all should belong to the utility model patent covering scope.
