Problems solved by technology

[0010] The disadvantage of this kind of experimental method is that when conducting experiments through the network, only the corresponding intelligent instruments can be operated, and there are fewer types of experiments completed, and the limitations are relatively large
This method can remotely control some intelligent instruments, but cannot remotely control real electronic circuit experimental circuits, without the use of actual circuits, and there is no possibility of multiple people sharing experimental instruments at the same time, but only completes the remote control of some instruments

Embodiment 1

[0048] Example 1: In figure 1 , Figure 6 Among them, the whole experimental system can be divided into three parts: client program, server program, server and controlled hardware equipment, including experimental instrument box, programmable oscilloscope (model is A54645D of Agilent Company) and signal generator (model is A33120A of Agilent Company).

[0049] The hardware equipment of the remote experiment system includes:

[0050] 1. A server and corresponding network equipment;

[0051] 2. A 54645D digital oscilloscope (the server is controlled through the GPIB interface);

[0052] 3. One A 33120A signal generator (the server is controlled by RS232 serial port);

[0053] 4. A test box (communicating with the server using RS485);

[0054] 5. A number of PC terminals (connected to the server through the network);

[0055] The client program has a signal generator, an oscilloscope software operation interface, and 26 experimental interfaces including circuits and systems...

Embodiment 2

[0088] Embodiment 2: experiment example

[0089] The following is an example of completing the most common operational amplifier experiment in university electrical experiments on the client side to illustrate the process of completing the entire experiment. The main body of the experiment is the operational amplifier LM324. The signal generator is used to input a 1KHz sine wave with an amplitude of 1V. The input and output terminals of the amplifier are observed with an oscilloscope. The output should be an amplified sine wave. At the same time, the feedback resistor can be changed to change the magnification.

[0090] 1) Register a user name and download the experimental client (any PC terminal in the network).

[0091] The user opens the program on the client, logs in and connects to the server, selects "Application of Operational Amplifier - Inverting Amplifier" on the program on the client, and connects the circuit in the program (such as Figure 5shown). Set the contro...
