Embodiment 1

[0030] Such as Figures 1 to 5 As shown, an error-proof teaching experiment platform is mainly used for students to learn and carry out chemical experiments, including loading system, traction system, identification system and control system.

[0031] The loading system includes a car body 1 and a reagent tray 2. The reagent tray 2 is detachably installed on the upper end of the car body 1. Different reagent trays 2 can be exchanged according to different experiments. The experimental categories of each mode are different. Corresponds to specific reagent tray 2. Described car body 1 comprises auxiliary tool drawer 3 and storage box 4, and described auxiliary tool drawer 3 is used for placing the auxiliary tools such as lighter, rubber gloves, record book needed in the chemical experiment, and storage box 4 is used for placing chemical experiment. Reagent etc.; described auxiliary tool drawer 3 comprises a plurality of, and a plurality of auxiliary tool drawers 3 are evenly in...

Embodiment 2

[0047] Such as Figure 6 As shown, the identification system includes a trigger light source and a wavelength detection camera 33, the trigger light source includes multiple types of light sources that can emit different wavelengths; the bottom end of the reagent tank 5 is provided with a light source placement groove; emit different wavelengths The trigger light sources are respectively installed in the light source placement grooves in different reagent areas; the wavelength detection camera 33 is installed above the reagent tray 2 through the address identification mounting frame 11, and the wavelength detection camera 33 is used for Trigger light sources for identifying different reagent zones. The signal output end of the wavelength detection camera 33 is electrically connected to the signal input end of the controller.

[0048] The traction system includes a traction motor 34, a transmission mechanism and a control panel 35. The traction motor 34 is installed at the low...

Embodiment 3

[0054] The identification system includes a light source and a detection and identification camera, the light source is installed around the identification installation board, and the detection and identification camera is installed in the middle of the identification installation board. An image processing module is preset in the detection and recognition camera, and the detection and recognition camera is used to detect what kind of reagent container is picked up on the reagent tray. The upper surface of the reagent tray is made of non-reflective material, which is used to better cooperate with the detection and recognition camera to identify the reagent.

[0055] The working principle of this embodiment is:

[0056] The reagent delivery personnel place the reagent container in the corresponding area on the reagent tray according to the reagent tank, and then place the reagent tray on the vehicle body; the on-site experiment operator moves the vehicle body to the correspondi...

Abstract

The invention provides a mistake-proof teaching experiment platform, which solves the technical problem that students add chemical reagents in a wrong order in the chemical experiment teaching process, and can enable the students to take the reagents in a correct order. The mistake-proof teaching experiment platform comprises a material carrier system, a traction system, an identification system and a control system. The material carrier system comprises a vehicle body and a reagent tray, wherein the reagent tray is detachably arranged at the upper end of the vehicle body; the reagent tray is divided into a plurality of reagent regions; and the reagent regions are respectively provided with a reagent groove. The identification system comprises an identification device and a two-dimensional mobile addressing driving platform, wherein the two-dimensional mobile addressing driving platform is arranged at the front end of the vehicle body. The identification system is connected with a controller. The control system is connected with an alarm device. The alarm device is arranged on the vehicle body. The beneficial effects are that the teaching experiment platform can monitor the reagent taking order of each student in the chemical experiment process to ensure that each operator can use, take and add the reagents in a specified order.

Description

technical field [0001] The invention relates to the field of teaching experiment devices, in particular to an error-proof teaching experiment platform. Background technique [0002] In the process of chemical experiment teaching, the order of adding chemical reagents often plays a key role in the results of chemical experiments. If the chemical reagents are added in the wrong order, not only will the experimental effect not be achieved, but dangerous consequences may even occur, threatening the safety of students. According to the current situation, most of them are taught by teachers, and students operate in accordance with the national reagent addition order according to the content taught by the teacher. However, some students are careless or cannot distinguish chemical reagents, and it is very likely that reagents are added in the wrong order. [0003] Therefore, it is necessary to provide a technical solution to solve the existing problems. Contents of the invention ...
