The six-axis attitude sensor 11 adopts a high-precision gyro accelerometer, reads measurement data through an internal processor thereof, and then outputs the measurement data through a serial port. It possesses multi-dimensional data output: acceleration 3 dimensions, angular velocity 3 dimensions and angle 3 dimensions. The output data includes: time, acceleration, angular velocity, and angle. Multiple experiments show that: when the shuttle car 7 is in the normal running state and the running state after derailing on the track 5, the values of the acceleration of the Z axis, the angular velocity of the X axis, and the angular velocity of the Y axis are greatly changed, and the average value of these data of the normal running state and the running state after derailing of the shuttle car 7 is taken as the reference value in this embodiment. When the data acquired by the six-axis attitude sensor 11 in the running process of the shuttle car 7 is smaller than the reference value, the shuttle car 7 is considered to run normally on the track 5; once the shuttle car 7 is derailed or broken, wheels of the shuttle car 7 fall onto a sleeper from the track 5, the car body of the shuttle car jolts and inclines greatly, at the moment, the values of the acceleration of the Z axis, the angular velocity of the X axis and the angular velocity of the Y axis are changed greatly, when the data output by the six-axis attitude sensor 11 is larger than a reference value, signals collected by the six-axis attitude sensor 11 are transmitted to the control terminal 1 through the serial server 14, the switch 15, the second bridge 19 and the first bridge 4, and the control terminal 1 controls the shuttle car 7 to stop through the serial relay 3.
2. The automatic hooking of the shuttle car 7 to the carriage 8 is accomplished by the laser ranging sensor 22.
When a carriage 8 is detected within a certain distance in the running process of the shuttle car 7, the dynamic distance between the shuttle car 7 and the carriage 8 is collected in real time, the collected dynamic distance is sent to the control terminal 1 through the serial server 14, the switch 15, the second bridge 19 and the first bridge 4, the control terminal 1 starts to display the dynamic distance, and when the distance between the shuttle car 7 and the carriage 8 reaches a set distance (such as 2500mm), the control terminal 1 controls the endless rope winch 6 to stop running through the serial relay 3, so that the shuttle car 7 and the carriage 8 complete automatic hooking by utilizing running inertia.
3. An obstacle encountered during the operation of the shuttle car 7 is detected by the ultrasonic obstacle sensor 12.
The ultrasonic obstacle sensor 12 continuously sends out fan-shaped ultrasonic signals in the running process of the shuttle car 7, when the existence of an obstacle is detected in the sensing distance, detection signals are sent to the control terminal 1 through the serial server 14, the switch 15, the second network bridge 19 and the first network bridge 4, and when the control terminal 1 determines that the detection signals are abnormal, the shuttle car 7 is controlled to stop running through the serial relay 3.
4. The running state of the shuttle car 7 is monitored in real time through the network camera 13.
The network camera 13 is used for monitoring the states of wheels and a track 5 in the running process of the shuttle car 7, and sending collected state data to the control terminal 1 through the switch 15, the second network bridge 19 and the first network bridge 4, and the control terminal 1 displays the working state of the shuttle car 7 in real time, so that if the shuttle car 7 has faults of derailment, shaft breakage and the like, the state of the shuttle car can be intuitively known, and a relevant department can be informed to process the fault in time.
5. The automatic unhooking of the shuttle car 7 from the carriage 8 is accomplished by the hook lever lifting mechanism 21.
The detailed process of automatically unhooking the shuttle car 7 from the carriage 8 is completed by the hook rod lifting mechanism 21, please refer to the working process described in the above specific composition structure of the hook rod lifting mechanism 21, and will not be described herein again.
6. Power supply
All the electric equipment on the shuttle car 7 is powered by the storage battery 18.
7. The shuttle car 7 is controlled by the sliding type charging device 20 to complete automatic charging.
The sliding charging device 20 controls the shuttle car 7 to complete the detailed process of automatic charging, please refer to the working process described in the specific structure of the sliding charging device 20, and the detailed description thereof is omitted here.
8. The signal warning lamp 23 is used for warning to remind the operating personnel of avoiding.
After the shuttle car 7 is started, the signal warning lamp 23 simultaneously gives out an alarm and a light signal to warn that the shuttle car 7 is running, so that the purpose of reminding operators to avoid is achieved. The detection of whether the shuttle car 7 is started or not can be realized by the six-axis attitude sensor 11. After the shuttle car 7 is started, acceleration values of an X axis and a Y axis of the six-axis attitude sensor 11 change, the data are transmitted to the control terminal 1 through the serial server 14, the switch 15, the second network bridge 19 and the first network bridge 4, after the control terminal 1 determines that the shuttle car 9 is in a running state according to the change of the values, a warning lamp starting instruction is transmitted back to the network IO controller 16 through the first network bridge 4, the second network bridge 19 and the switch 15, the signal warning lamp 23 gives out sound alarm and flashes, and therefore the purpose of warning operators to avoid is achieved.
It is to be understood that the above embodiments are merely exemplary embodiments that have been employed to illustrate the principles of the present invention, and that the present invention is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
