GC-10B touch screen control tolerance fit and technical measurement multifunctional voice display cabinet (high-end model)
1、 Overview:
The "Tolerance Fit and Technical Measurement" demonstration display cabinet is an electronic teaching equipment designed by introducing the most mainstream teaching philosophy of tolerance fit and technical measurement, combining with the 12th and 13th Five Year Plan textbooks, and combining with the mechanical teaching syllabus of universities, vocational schools, technical schools, and vocational schools. A cognitive experimental equipment designed and produced based on the basic content of interchangeability and technical measurement courses. It systematically and vividly displays the tolerance fit between holes and shafts, geometric tolerance items and annotations, surface roughness, precision design of typical parts, and measurement of dimensions and positional errors through physical objects or models, combined with corresponding graphic and textual materials, with the aim of improving learners' intuitive understanding of tolerance fit and technical measurement. The display cabinet can be used to conduct a Cognitive Experiment on Tolerance Fit and Technical Measurement.
2、 Technical specifications:
1. This display cabinet is composed of ten individual display cabinets, with an external dimension of 1200 × five hundred and fifty × 1860mm (width × thick × High. Material: The cabinet is made of SPCC cold-rolled steel plate with a net thickness of 1.0mm or more, which is processed by bending, welding, phosphating, and spray painting (orange matte treatment), and is finely processed. The cabinet body has good steel properties, and the process is carefully designed to ensure that there are no scratches when the coin is scratched. The panel inside the cabinet is composed of laser printed text annotations and photographic charts, which are professionally coated and rolled without bubbles. The model material inside the cabinet is a combination of aluminum alloy, physical objects, partially transparent organic glass, and engineering plastics. Beautiful and elegant appearance, durable and long-lasting.
2. The model actions and explanations of the mechanism in the display cabinet are composed of a new second-generation multifunctional voice playback control system:
2.1. The system control is equipped with password protection function. If the teacher does not provide a password, students cannot start the touch screen, which provides strong protection for controlling the entire product. The control program sequence is composed of touch screen buttons, microcontroller, relay, sound player, model, etc.
2.2. Touch screen (available from different brands with different specifications of 4.3 inches, 5 inches, and 7 inches), the touch screen program includes: welcome interface, password input interface, and control interface,
2.3. The key content includes: sound size control key, loop playback key, pause key, and number key, etc. The synchronization of model actions and voice explanations can be achieved through button operation.
3. The top of the display cabinet is equipped with lighting fluorescent lamps and control switches, and the back of the cabinet is equipped with opposite doors, which is beneficial for maintaining equipment and facilitating repairs. There is a cabinet box at the bottom of the cabinet, which facilitates the storage of individual models, experimental boxes, and related experimental documents. The bottom of the cabinet is equipped with universal wheels, which are easy to move and meet the requirements of human-machine engineering.
4. Other configurations include a microcomputer (microcontroller voice chip) control board.
4.1. 10 manual control boards; 10 large capacity language chip control boards
4.2. 10 sets of audio systems, power: 6W; Word interpretation playback effect: The sound in a 100 square meter room is loud and clear.
5. Input voltage: AC 220V ± 10% 500W.
6. The contents of the display cabinet are shown in the table below: the glass and locks on the display cabinet will be provided by the school according to their own needs.
