specific Embodiment approach 1

[0033] Specific implementation mode one: combine Figure 1 to Figure 4 This embodiment is described in detail, which includes a power supply 1, a data processing and control module 2, a digital IO3, a multimeter chip 4, a wireless module 5, a USB interface 6, a plurality of digital-to-analog converters 7, a plurality of filters and Operational amplification circuit 8, a plurality of analog-to-digital converters 9, a plurality of capture circuits 10 and a customized module 11;

[0034] The power supply 1 includes a DC stabilized voltage source and a current source chip;

[0035] Multiple digital-to-analog converters 7 correspond one-to-one to multiple filtering and operational amplifier circuits 8, and multiple analog-to-digital converters 9 correspond to multiple capture circuits 10 one-to-one;

[0036] The output control signal end of the data processing and control module 2 is connected to the control signal input end of the digital-to-analog converter 7, and the analog sig...

specific Embodiment approach 2

[0053] Embodiment 2: This embodiment is a further description of the portable electronic experiment teaching platform described in Embodiment 1. In this embodiment, the wires used for connection are connected in series with an isolation chip.

[0054] The isolation chip can effectively protect the work of each device in the circuit from interfering with each other, and can also protect the chip from being burned due to high current and high voltage; in addition, the input part (analog-to-digital converter and multimeter) and When the power supply of the output part (voltage source, current source, digital-to-analog converter) adopts an isolated chip, the input and output of these functional circuits can be connected in parallel or in series arbitrarily without causing a short circuit.

Abstract

A portable electronic experimental teaching platform relates to an experiment teaching platform, and is disclosed in order to solve the problem that the existing electronic experimental teaching platform equipment is expensive and not portable, and cannot store or reprocess acquired data easily. The platform comprises a power supply, a data processing and control module, a digital IO, a universal meter chip, a wireless module, a USB interface, multiple digital-to-analog converters, multiple filter and operational amplifier circuits, multiple analog-to-digital converters, multiple capture circuits, and a custom module. The portable electronic experimental teaching platform is suitable for experimental teaching.

Description

technical field [0001] The invention relates to an experimental teaching platform. Background technique [0002] In the experiments of electronic courses such as circuit experiments, signal and system experiments, digital circuit experiments, and analog circuit experiments, signal generators and signal acquisition and analysis equipment (such as oscilloscopes, spectrum analyzers, network analyzers, etc.) need to be used. Measuring equipment such as multimeters will be used. [0003] The price of these devices is not cheap, and students cannot buy them separately, and the school cannot equip each student with a set of equipment. They often equip each experimental bench in the laboratory with one set, and they are all relatively cumbersome. Therefore, these devices on the electronic experimental bench Both occupy a large part of the space and are not portable; [0004] Existing experiments all arrange a fixed time for students to conduct experiments in the laboratory, and th...
