Description

Technical Field

[0001] The invention belongs to the technical field of port portal cranes, and in particular relates to an intelligent scoring system for skill operation of port portal cranes. Background Art

[0002] In the "Bucket Walking in the Channel" project of the port gantry crane skill operation competition, manual judgment is used to determine whether the bucket is walking on the prescribed route, including the number of times the bucket deviates from the single-line (double-line) walking route, and the cumulative deviation time, etc., which are difficult to judge and count manually, and the final scoring result is greatly affected by human subjective evaluation, making it difficult for the project competition to be truly fair and just.

[0003] In order to enable the contestants to truly demonstrate their operational skills and ensure that the competition is truly fair and just, the present application provides an intelligent scoring system for the skill operation of port gantry cranes. A computer monitors the entire process of the bucket walking in the channel in real time, automatically accumulates the number of times the bucket deviates from the prescribed route and the duration of the deviation, and automatically generates the contestant's final score to ensure fairness throughout the competition.

[0004] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent scoring system for skill operation of a port gantry crane, so as to solve the problem that the manual judgment of whether the bucket is walking on the prescribed route in the "bucket walking in the channel" competition project is greatly affected by human subjective evaluation.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] Intelligent scoring system for port gantry crane skill operation, including:

[0008] The bucket walking channel consists of 4 channels forming a square area;

[0009] Infrared sensors, two groups are set at both ends of each channel to detect the deviation of the bucket; the infrared rays emitted by the two groups of infrared sensors form a prescribed walking route;

[0010] PLC, receiving the signal of the infrared sensor, is used to record the number of times the bucket deviates from the line and the accumulated time, and automatically generates the score of the player according to the scoring rules;

[0011] A computer with WINCC system installed is used to read PLC data and display the final scores of contestants.

[0012] Preferably, the bucket is a φ60 cm round barrel; the infrared rays emitted by the two groups of infrared sensors are 40 cm apart.

[0013] As a preferred method, the system scoring rules include four situations, namely:

[0014] Case A: The barrel completely blocks both infrared rays, and the system does not deduct points;

[0015] Case B: If the barrel deviates from any infrared ray, the system will automatically accumulate the number of deviations and duration, and deduct points at 0.2 minutes per time and 0.1 minutes per second respectively;

[0016] Case C: The barrel deviates from the two red lines. The system automatically accumulates the number and duration of deviations and deducts points at 0.4 points per time and 0.2 points per second respectively.

[0017] Case D: The top of the barrel exceeds the height of the pole. The system automatically accumulates the number and duration of deviations and deducts points at 0.4 minutes per time and 0.2 minutes per second respectively.

[0018] Preferably, the height of the vertical pole is 2m; when the top of the barrel exceeds the height of the vertical pole, the bottom of the barrel exceeds the height of the infrared rays emitted by the infrared sensor and no longer blocks the infrared rays.

[0019] Compared with the prior art, the present invention has the following beneficial effects: the intelligent scoring system for skill operation of port gantry cranes of the present invention arranges infrared sensors at both ends of the bucket walking channel to monitor the entire walking process of the competition bucket in the channel in real time. The PLC system automatically accumulates the number of times the bucket deviates from the prescribed walking route and the deviation walking time. The final score of the player is automatically generated through system software calculation, avoiding the problem that the final scoring result determined manually is greatly affected by human subjective evaluation, which is conducive to ensuring fairness and justice throughout the competition.

[0028] See attached Figure 1-6 , the intelligent scoring system for port gantry crane skill operation includes:

[0029] The bucket walking channel consists of 4 channels forming a square area;

[0030] Infrared sensors, two groups are set at both ends of each channel to detect the deviation of the bucket; the infrared rays emitted by the two groups of infrared sensors form a prescribed walking route;

[0031] PLC, receiving the signal of the infrared sensor, is used to record the number of times the bucket deviates from the line and the accumulated time, and automatically generates the score of the player according to the scoring rules;

[0032] A computer with WINCC system installed is used to read PLC data and display the final scores of contestants.

[0033] In this embodiment, the bucket is a φ60 cm round barrel with a height of 100 cm. Figure 2 As shown. The infrared sensor is installed on the infrared sensing frame, which is 135 cm high and 70 cm wide. The infrared rays emitted by the two groups of infrared sensors are 40 cm apart, and the infrared sensor is 100 cm above the ground.

[0034] See attached Figure 1 , a prescribed route for the bucket to walk is built through the infrared sensor. Among them, the yellow color is the channel for the bucket to walk. Each channel is equipped with 2 sets of infrared sensors, which emit infrared rays 40cm apart to form the prescribed walking route. The competition requires that when the bucket walks in the yellow channel, it must be within the real-time infrared monitoring range. If it walks away from any infrared line, it is not in accordance with the rules and is regarded as walking away from the inner line (outer line). The system will automatically record the number of deviations and the cumulative deviation time (unit: seconds).

[0035] The signal of the infrared sensor is connected to the PLC. Through the programming design of the PLC system software, the number of deviations and the duration are accumulated. The scoring rules are as follows: Figure 3 There are 4 cases, namely:

[0036] Case A: The barrel completely blocks both infrared rays, and the system does not deduct points;

[0037] Case B: If the barrel deviates from any infrared ray, the system will automatically accumulate the number of deviations and duration, and deduct points at 0.2 minutes per time and 0.1 minutes per second respectively;

[0038] Case C: The barrel deviates from the two red lines. The system automatically accumulates the number and duration of deviations and deducts points at 0.4 points per time and 0.2 points per second respectively.

[0039] Case D: The top of the barrel exceeds the height of the pole. The system automatically accumulates the number and duration of deviations and deducts points at 0.4 minutes per time and 0.2 minutes per second respectively.

[0040] The height of the pole is 2m; when the top of the barrel exceeds the height of the pole, its bottom exceeds the height of the infrared rays emitted by the infrared sensor and no longer blocks the infrared rays. The final score of the contestant is automatically generated through system software calculation. The system software design package block refers to the attached Figure 4 and 5 .

[0041] Use the computer to install the WINCC system software. WINCC reads the PLC data and displays the final scores of the contestants. The system scoring screen is as shown in the attached Figure 6 shown.

[0042] The intelligent scoring system for skill operation of port gantry cranes of the present invention uses a computer to monitor the entire process of the bucket walking in the channel in real time, automatically accumulate the number of times the bucket deviates from the prescribed route and the duration of the deviation, and automatically generate the final score of the contestant. This can solve the problem that manual judgment of whether the bucket walks on the prescribed route in the "bucket walking in the channel" competition project is greatly affected by human subjective evaluation, so that fairness and justice are achieved throughout the competition, and it is very practical and has good market application prospects.

[0043] The foregoing description of specific exemplary embodiments of the present invention is for the purpose of illustration and demonstration. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings.
