Detailed Description of the Preferred Embodiments The technical solutions in the embodiment are described clearly and completely in combination with the drawings in the embodiment of the invention.
Apparently, the described embodiment is only part but not all of the embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without creative work shall fall into the protection scope of the invention.
Referring to Figs. 1-3, an automatic control system for automobile loading and transportation counting, comprising a PLC input unit 1 and a PLC output unit 2, wherein the PLC input unit 1 consists of a digital counter 11 and a laser correlation photoelectric switch power supply 12. The digital counter 11 is used for displaying automobile counting and saving the counting results, and the laser correlation photoelectric switch power supply 12 is used for providing operating power for a laser correlation photoelectric switch A and a laser correlation photoelectric switch B.
The PLC output unit 2 consists of a CPU chip 21, a green light HL1 outside the bunker gate, a red light HL2 outside the bunker gate, a green light HL3 inside the bunker gate, a laser correlation photoelectric switch A and a laser correlation photoelectric switch B; wherein, the CPU chip 21 is used to control the operating state of the electrical components and to scan the input signal cyclically through the set program; the green light HL1 outside the bunker gate is used to indicate that the vehicle is allowed to enter the bunker; the red light HL2 outside the bunker gate is used to indicate that the vehicle is not allowed to enter the bunker,
> LU500666 the green light HL3 inside the bunker gate is used to indicate that the vehicle enters the bunker at the correct position; the laser correlation photoelectric switch A is used to detect the position of the inner-side compartment rear, the laser correlation photoelectric switch B 1s used to detect the position of the outer-side compartment head.
The power input end of the digital counter 11 is connected to the live wire L and neutral wire N, the signal input end of the digital counter 11 is connected to a relay KA, the power input end of the relay KA is connected to the live wire L and neutral wire N, and the power input end of the laser correlation photoelectric switch power supply 12 is connected to the live wire L and neutral wire N.
A Q0.0 pin of the CPU chip 21 is connected to the green light HL1 outside the bunker gate, a Q0.1 pin of the CPU chip 21 is connected to the red light HL2 outside the bunker gate, a Q0.2 pin of the CPU chip 21 is connected to the green light HL3 inside the bunker gate, a Q0.3 pin of the CPU chip 21 is connected to the relay KA, the laser correlation photoelectric switch A is connected to an 10.0 pin and a L+ pin of the CPU chip 21, and the laser correlation photoelectric switch B is connected to an 10.1 pin and a L+ pin of the CPU chip 21.
Principle of the system: When the CPU chip 21 is powered on, the green light HL1 outside the bunker gate is on, and vehicles are allowed to enter; when a vehicle enters in a head-back way, the vehicle compartment interrupts the action of laser correlation photoelectric switch B, the red light HL2 outside the bunker gate is on and the green light HL1 outside the bunker gate is off, so other vehicles are not allowed to enter.
When the vehicle moves backwards to the position under the funnel, the laser correlation photoelectric switch A acts, at this time the green light HL3 inside the bunker gate is on, which is a signal to the driver of right vehicle position and loading ready. In the process, the driver controls the vehicle to move back and forth slightly to make sure that the vehicle is fully loaded, and the laser correlation photoelectric switches A and B are used for logic control to avoid counting error due to false triggering.
After loading is completed, the vehicle moves out of the bunker, CPU chip 21 controls the relay KA to output signal to the digital counter 11; at the same time, the red light HL2 outside the bunker gate is off, and the green light HL1 outside the bunker gate is on, so the next vehicle is allowed to proceed with loading and transportation.
In the automatic control system for automobile loading and transportation counting, the compartment height and length of the tailings transportation vehicles can be measured in advance to differentiate the loading vehicles from others and avoid counting error and misuse of scooptram. The measuring results shows that the compartment is 8.2-8.7m long and 3m high, so the laser correlation photoelectric switches À and B can be installed at a height of 2.8 to the ground with a space of 7m, and at a horizontal level.
In the automatic control system for automobile loading and transportation counting, the outdoor waterproof laser correlation photoelectric switches À and B are installed in place, the incoming and outgoing vehicle signals are acquired on site for cyclical scanning by the CPU chip 21, the switch signal is output by the relay KA, vehicle counting results are displayed and saved by the electronic digital counter 11. Therefore, the system can be used for vehicle counting through automatic control, with the advantages of high accuracy, stability and reliability, and significantly reducing labor cost.
