JGK-095 Excavator Simulator Introduction
The excavator simulator is the latest product developed by our company based on the latest excavator driver training outline and the latest driving simulator industry standard (JT / T398-2005). The cockpit has undergone a lot of technical innovations and improvements, and is configured. The latest version of "WJR Excavator Simulation Software 9.0" is provided. This software provides rich and realistic various operating topics and functions, making it the preferred teaching equipment for excavator training schools.
1. Operating parts
The operating parts are composed of driver's seat, brand computer, video screen (22-inch LCD display), high-sensitivity operation handle, walking operation lever, hydraulic safety lock lever, data acquisition card, and various function adjustment components.
The device contains the same operating parts as a real excavator, left and right operating handles, walking pedal levers, throttle size adjustment, hydraulic safety lock lever, walking speed adjustment and other components. (The device can perform networked training or stand-alone training; using the console computer, up to 30 devices can be connected to a training scene for training, which is optional.)
By operating realistic operating parts, students learn about accurate signal acquisition, calculation, and processing, and finally output a three-dimensional scene corresponding to the operation and a real-time operation interface with various voice prompts on the video screen.
Second, the main function
The simulator is equipped with the latest WJR excavator simulation software version 9.0, which is designed for our company in accordance with the latest standards of the excavator training industry. It has independent intellectual property rights and is the latest software that combines theoretical and practical evaluation.
The software uses a multi-degree-of-freedom digital model of the excavator to implement realistic simulations of the excavator's various steering, walking, large and small arms, and bucket movements. In addition, the latest computer technology is used to realize real three-dimensional scenes and realistic sound simulations.
1. The training subjects conduct operation training according to three modes: basic training, assessment operation and theoretical learning.
a) Basic training mode: air movement, earth excavation training, walking driving, loading training, trenching training, leveling training, up and down board, up and down slope, and broken training.
b) Evaluation operation mode: Excavation, dumping, loading, loading, ditching, brushing, leveling training, up and down board, up and down, and crushing training.
c) Theoretical study includes:
1) Theoretical documents: Contains nearly a thousand theoretical documents on safety, operation and maintenance of the excavator. Rich and detailed pictures and text descriptions completely solve the shortcomings of the lack of theoretical knowledge in the teaching of the training school!
2) Teaching video: With this function, you can play a variety of safety, maintenance, operation knowledge and other teaching videos of 24 disk excavator, loader and forklift operation, providing trainees with practical and standardized actual real machine operation drills!
3). Theoretical assessment: Referring to the national standard GB5306-85 "Special Operations Staff Safety Technology Assessment Management Rules", according to the safety education and training syllabus and teaching materials, 1080 standardized test questions have been prepared. In addition, it provides the function of adding a local question bank. To help students pass the theoretical exam smoothly!

a) Switching the forehand operation module: Through this module, a teaching device can be used to simultaneously perform excavator (backhand and forehand excavator) training in two different operation modes!
b), walking speed gear module: through the choice of walking speed rabbit gear and tortoise gear, realistically reproduce the changes and differences in excavator walking speed!
c) Throttle control module: Simulate the change of the throttle control size of the excavator to provide suitable operating speeds for students with different operating topics and different proficiency levels!
d) Perspective window transformation module: Different operating perspective transformations are adopted to help students more easily observe the effects of simulation operations, and at the same time, operation instruction videos that are consistent with the topic are added to help students understand the gaps and deficiencies in the simulation operations and standard operation actions in real time. !!
