Embodiment 1

[0030] see figure 1 , the remote experiment realization method of the present invention, form remote experiment system by user computer, management server, experiment computer and test box, wherein user computer, management server and experiment computer are all in network environment, realize the software and hardware of experiment object by following steps Remote operation:

[0031] 1) First, the user sends an experiment request to the management server through the client connection program on the user computer;

[0032] 2) After the management program on the management server checks the occupancy of the experimental computer, it will feed back to the user whether there is an idle experimental computer; if so, the management server will notify the experimental computer through the network to establish a connection program with the client computer of the user computer through the experimental computer management program. remote Desktop connection;

[0033] 3) After the user...

Embodiment 2

[0035] see figure 1 , figure 2 , the remote experiment implementation method of the present embodiment is different from Embodiment 1 in that the experiment box is composed of the minimum system of a single-chip microcomputer, an experimental peripheral circuit, an FPGA chip, an FPGA peripheral configuration circuit, a multiplexer switch and a power supply; The hardware configuration communication port downloads the hardware connection information of the experiment content to the FPGA chip. The connection logic inside the FPGA selectively connects the pins of the single-chip microcomputer and the peripheral circuit wiring according to the content sent by the experimental computer, and at the same time controls the multiplexer switch as needed. state; the experimental computer downloads the single-chip microcomputer program to the single-chip microcomputer chip through the program download port and starts the experiment; at the same time, embeds the serial communication subrou...

Embodiment 3

[0037] seefigure 1 , figure 2 , the remote experiment implementation method of this embodiment is further different from Embodiment 2 in that: Figure 5 As shown, the experimental computer management program is composed of the experimental remote visualization system, serial communication implantation program, C51 integrated programming environment and single-chip program download tool. The visualization system consists of a visualization experiment operation interface, a compilation tool, a video observation window, a download tool and serial communication. The user selects the experiment type in the visual experiment operation interface and configures the hardware connection by dragging and dropping the mouse. After completing the hardware connection configuration, use the compiling tool to generate connection data for communication with FPGA, and transmit it to FPGA through the serial port communication module. Then, the user writes the experimental program in the C51 in...

Abstract

The invention relates to a method and a system for a remote experiment. A remote experiment system is composed of a user computer, a management server, an experiment computer and a test chamber and is used for realizing the following hardware and software remote operations for an experimental subject according to the method for realizing the remote experiment: 1) sending an experiment request to the management server by a client connecting program on the user computer; 2) checking the occupation condition of the experiment computer by a management program on the management server, and if an idle experiment computer exists, establishing a remote desktop connection by the management server through the management program of the experiment computer and the client connecting program of the user computer; 3) after connecting the user computer with the experiment computer, starting a visual remote experiment system by a user on the remote desktop and performing hardware and software operations on the experimental subject. A single-chip remote experiment system is composed of the user computer, the management server, the experiment computer and the test chamber, wherein the test chamber is composed of a single-chip minimum system, an experimental peripheral circuit, a FPGA (Field Programmable Gate Array) chip, a FPGA peripheral configuration circuit, a multi-circuit switch and a power supply.

Description

technical field [0001] The invention relates to a remote experiment system, in particular to an experiment method and a single-chip remote experiment system based on the simultaneous remote operation of the hardware and software of the experiment system. Background technique [0002] The experiment link is an indispensable practice method in the teaching system of engineering colleges. It cultivates students' comprehensive quality and innovation ability, enables students to consolidate theoretical knowledge, applies theory to practice, and cultivates students' hands-on ability, thereby deepening their understanding of theoretical knowledge. understand. However, the current experimental mode, which is mainly taught by teachers, can only be passively accepted by students, and cannot give full play to their innovative ability. If the experimental equipment is insufficient, students cannot directly participate in the operation of the experimental process. In addition, this tea...
