National Competency Standards-based Construction Machine Loader Training System and Training Method therefor

The present invention relates to a National Competency Standard (NCS)-based construction machine loader practice education system and a practice method using the same, and more specifically, a new alternative that can supplement and reinforce construction machine practice education (pilot training) using advanced technology By adding experiential and practical training to the training guidelines of the National Competency Standard (NCS) in actual equipment training, it is possible to provide sufficient practical training to pilots to improve the learning effect, and to compensate for the lack of job competency through safe practical training. It relates to a construction machine loader practice education system based on the National Competency Standards (NCS) and a practice method using the same.

In general, the number of test takers for construction machinery operation is increasing every year, and in 2017, there were 131,000 people, but there are 250 heavy equipment training centers across the country, and in particular, the provision of practical training is very insufficient.

According to the definition of facilities, 1.5 m2 per lecture room, 3.0 m2 per person in rescue practice room, 15 m2 per person in operation practice.

This is due to the high cost of training equipment, difficulties in securing a training site, and insufficient training, the average daily practice time per person is less than 11 minutes, and the total amount of practical training is operated for about 3 hours. Training in the form of hands-on training is conducted, which leads to insufficient practical training job competency.

In addition, construction machinery operation has a process of digging, cutting, loading and unloading, stacking, and filling, but training on actual equipment. Progressive and passive education It is not possible to provide a wide range of practical education.

These construction machinery and automobile training courses have high operating and maintenance costs such as oil, consumable exchange, maintenance, and one-person practice place.

Meanwhile, in recent years, a vicious cycle of lack of a solution to supplement the problems of construction machinery practice continues due to the fact that the simulator is a realistic supplementary method for practical training, high development cost, lack of diversity in content, and limitations in introduction.

Accordingly, it is a complementary method to provide practical training that meets the national job competency standard (construction machine operation and maintenance). By introducing simulator education, there is a need to develop human resources.

A remote control robot system for underwater work and its control method that can significantly improve the work efficiency and range of a remotely operated vehicle (ROV) newly developed for underwater construction and reduce labor costs. is described.

However, Prior Patent 2 is a configuration that allows the actual underwater robot to be controlled from a remote location where the boarding space is implemented. There is a problem in that practical education cannot be provided because it is to provide an environment for

In addition, absolute evaluation of the operator's ability according to the mission is recorded, and the operation data generated during the evaluation is recorded in the storage unit 220 .

The simulation operation unit 240 performs actual simulations generated when the simulator is operated. The simulation process is visualized in real time and transmitted to the monitor and HMD.

The operation unit 250 is an operation part of the simulator 1 200 , and receives input from a joystick, pedal, wheel, lever, on/off switch, and HMD sensor, and performs monitor and HMD output, and the like.

The screen display unit 260 displays a warning on the screen if the value of each element of the operation unit is low based on the operation distribution value with the highest frequency when an accident occurs, a warning if it is included in the distribution value, and an alarm if it is high.

For example, when the results obtained from data analysis are close to the type value of a rollover accident. "Rollover risk detection" is displayed, the accident occurrence distribution value of the preset safety standard table is displayed, and each operation value of the driver is linked to the display unit, and the position of the driver's operation value is compared based on the accident occurrence distribution value to ensure safety. /Warning/Danger is displayed on the screen display unit 260 .

The construction machine training system server 300 is basically composed of an operation server 310 and a DB server 320 , but in addition, the big data operation unit 330 and the safety standard information 340 are interlocked to operate.

And the construction machine training system server 300 remaps the curriculum by analyzing the safety accident-inducing behavior of the beginner from the data stored according to the simulator operation (S250).

On the other hand, FIG. 19 is a flowchart for evaluating the occurrence of an unexpected event in the construction machine loader practice training, and the unexpected event occurrence evaluation method starts the evaluation operation as shown in FIG. 19 (S161), and when the unexpected event occurs (S162) ), and receives a safety value corresponding to the unexpected event (S163).

Then, it is determined whether the unexpected event has ended (S164), and if it is over, a safety value (corresponding value) for the learner's unexpected event is received (S165), and the evaluation operation is terminated.

20 to 20D are flowcharts showing the evaluation step process in the construction machine loader practical training evaluation method.

As shown in Figure 5a, the loader practice evaluation evaluates the job competency standard (NCS)-based job competency to derive the result.

21 is a flowchart showing the process of the operation ability learning step in the construction machine loader practical training method.

As shown in FIGS. 5 and 21 , in the practice operation step ( S200 ), first, inspection items are checked before operating the construction machine through the simulators ( 200 , 201 , 202 ) ( S2010 ).

The work is loaded through the construction machine on which the movement is completed (S2040), and the loaded work is transported to the test evaluation location (S2050).

The evaluation site is flattened through the work transported to the test evaluation position (2060), and safety and environmental management matters according to the occurrence of an emergency for the construction machine undergoing leveling are checked (S2070).

After the work of the construction machine on which the environmental and safety management items have been completed, the basic inspection items are checked to complete the operation practice through the simulator (S2080).

The present invention made in this way has the effect that, first, the practical training simulation is possible for the basic operation method based on the NCS education module.

It has the effect of quickly compensating the driver's wrong operating habits by mapping it and using it for the safety training prior to training.

Third, since the installation space is small, there is no waiting time before operation, such as non-use of the internal combustion engine, preheating and preparation time for training place, there is no pollution, and it has the effect of innovatively lowering the maintenance cost of oil and consumables.

Fourth, by applying the VR HMD, you can escape from the limited environment provision of the existing monitor method and immerse yourself in a wide range of real situations responding to the operator's active actions.
