[0057] The present application embodiment provides an experimental teaching method for remote experiments using remote control technology, which can be applied to electronic devices such as servers, personal computers, smart phones, tablet computers, etc. Figure 1 As shown, the experimental teaching method for conducting remote experiments using remote control technology may include the following steps S101 to S104:

[0058] Step S101, pre-installing movable rollers under each experimental item of the remote experiment;

[0059] Step S102, obtaining the initial position coordinates and the destination position coordinates of each experimental item in the remote experiment;

[0060] Step S103, obtaining control button information for controlling the movement of the roller under each experimental product according to the initial position coordinates and the destination position coordinates of each experimental product in each experimental product;

[0061] Step S104, providing the obtained control button information for controlling the movement of the rollers under each experimental product to the student end, and then receiving the remote control instructions input by the students at the student end according to the control button information for controlling the movement of the rollers under each experimental product, and then controlling the movement of the rollers under each experimental product according to the remote control instructions.

[0062] The experimental teaching method for conducting remote experiments using remote control technology provided in the embodiment of the present application can realize experimental teaching remotely, solve the problem of time and place limitations of students' experiments in traditional experimental teaching, and improve the efficiency of experimental teaching; moreover, remote experimental teaching improves the utilization rate of experimental resources and saves resources.

[0063] In the embodiment of the present application, a possible implementation method is provided. In the above step S102, the destination position coordinates of each experimental product of the remote experiment are obtained, which can specifically be the destination position coordinates of each experimental product of the remote experiment selected by the student at the student end on the experimental platform interface of the display device. In this way, what you see is what you get on the experimental platform interface, and the student at the student end can conveniently perform the experimental operation.

[0064] A possible implementation method is provided in the embodiment of the present application. In the above step S103, the control key information for controlling the movement of the roller under each experimental product is obtained according to the initial position coordinates and the destination position coordinates of each experimental product in each experimental product. Specifically, the following formula may be used to obtain the control key information for controlling the movement of the roller under each experimental product according to the initial position coordinates and the destination position coordinates of each experimental product in each experimental product;

[0065]

[0066] Among them, T H,i represents the time control value of the left and right buttons corresponding to the horizontal movement of the roller under the i-th experimental product; T Z,i represents the time control value of the up and down buttons corresponding to the longitudinal movement of the roller under the i-th experimental supplies; K represents the screen ratio of the experimental platform interface of the display device at the student end to the actual experimental interface; (X i ,Y i ) represents the initial position coordinates of the ith experimental item before the remote experiment begins; (X i,0 ,Y i,0 ) represents the target position coordinates of the i-th experimental supplies selected by the student on the experimental platform interface of the display device; V represents the set moving speed of the scroll wheel;

[0067] When T H,i ≥0, it means you need to control the left button and hold T H,iThe time of the control key information is to control the left key and hold T H,i time;

[0068] When T H,i When <0, it means you need to control the right button and hold |T H,i | time, that is, the control key information is to control the right key and hold |T H,i |Time;

[0069] When T Z,i ≥0, it means you need to press the down button and hold T Z,i The time of the control key information is to control the down key and hold T Z,i time;

[0070] When T Z,i When <0, it means that you need to control the up button and hold |T Z,i | time, that is, the control key information is to control the up key and hold |T Z,i |time.

[0071] It can be seen that this embodiment adopts the above formula to obtain the control button information for controlling the movement of the roller under each experimental product according to the initial position coordinates and the destination position coordinates of each experimental product in each experimental product, thereby improving the efficiency of remote control.

[0072] A possible implementation method is provided in an embodiment of the present application. Since there is a network delay in remote control and students may not be able to strictly maintain the above-mentioned movement time when operating the buttons, it is necessary to perform the next step of system auxiliary control, that is, in the process of controlling the movement of the rollers under each experimental product according to the remote control instructions, monitor the coordinates between the real-time position of each experimental product and the destination position, and perform corresponding operations based on the monitoring results.

[0073] In the above embodiment, the coordinate situation between the real-time position of each experimental product and the target position is monitored, and corresponding operations are performed according to the monitoring results. Specifically, the following formula can be used to determine whether the horizontal and vertical coordinates of each experimental product overlap with the horizontal and vertical coordinates of the target position after eliminating the network delay of the remote control;

[0074]

[0075]

[0076] Where ΔX i (t) represents the difference between the horizontal coordinate of the i-th experimental item and the horizontal coordinate of the destination position at time t after eliminating the network delay of the remote control; ΔY i(t) represents the difference between the ordinate of the i-th experimental item and the ordinate of the destination position at time t after eliminating the network delay of the remote control; X i (t) represents the horizontal coordinate of the i-th experimental item on the experimental platform interface of the student-side display device at time t when the network delay of remote control is not eliminated; Y i (t) represents the ordinate of the i-th experimental product on the experimental platform interface of the student-side display device at time t when the network delay of remote control is not eliminated; B represents the amount of data transmitted for transmitting the control instruction of the student to remotely control the movement of the roller under each experimental product according to the control key information of controlling the movement of the roller under each experimental product; V B Indicates the transmission network speed of remote control;

[0077] If ΔX i (t) = 0, which means that the horizontal coordinate of the i-th experimental item at time t overlaps with the horizontal coordinate of the target position;

[0078] If ΔX i (t)≠0, it means that the horizontal coordinate of the i-th experimental item at time t does not overlap with the horizontal coordinate of the target position;

[0079] If ΔY i (t) = 0, which means that the ordinate of the i-th experimental item at time t overlaps with the ordinate of the destination position;

[0080] If ΔY i (t)≠0, it means that the ordinate of the i-th experimental item at time t does not overlap with the ordinate of the destination position; and

[0081] If after eliminating the network delay of remote control, the horizontal and vertical coordinates of the experimental product overlap with the horizontal and vertical coordinates of the target position, the remote control of the experimental product in the corresponding direction is cut off and the roller is braked. In addition, the unit of B can be bit, V B The unit may be bit / s, which is not limited in the embodiment of the present invention. This embodiment can realize auxiliary control and ensure the reliability of remote control; and can eliminate the influence of network delay and prevent students from failing to strictly keep the moving time when operating the keys.

[0082] The embodiment of the present application provides a possible implementation method. When the remote control of the experimental product in the corresponding direction is cut off and the roller is braked, a remote cut-off instruction may be generated, and the remote control of the experimental product in the corresponding direction is cut off and the roller is braked according to the remote cut-off instruction. In this embodiment, since the start and braking process of the roller is very short, the start and braking distances can be ignored, which can ensure that the experimental product can accurately reach the destination, and can also prevent the situation where the experimental product is out of the target position due to the long time of controlling the button during remote control by the student, thereby improving the accuracy of remote control.

[0083] A possible implementation method is provided in an embodiment of the present application. After controlling the rollers under each experimental supply to move to the destination position according to the remote control instruction, the accuracy of the student's experiment can be analyzed according to the position where each experimental supply is placed, and corresponding prompt operations can be performed according to the analysis results. For example, when it is analyzed that the student's experiment is inaccurate, the student can be reminded in time.

[0084] Further, in the above embodiment, the accuracy of the student's experiment is analyzed according to the positions of the experimental supplies, and the corresponding prompt operation is performed according to the analysis result. Specifically, the following formula can be used to analyze the accuracy of the student's experiment according to the positions of the experimental supplies;

[0085]

[0086] Among them, δ i represents the red control value of the i-th experimental supplies on the experimental platform interface of the student-side display device; X i,min Indicates the minimum value of the horizontal coordinate in the correct setting position range of the i-th experimental product; X i,max Indicates the maximum value of the horizontal coordinate in the correct setting position range of the i-th experimental product; Y i,min Indicates the minimum value of the ordinate in the correct position range of the i-th experimental item; Y i,max It represents the maximum value of the vertical coordinate in the correct position range of the i-th experimental product;

[0087] If δ i =0 means that the position of the i-th experimental supplies is correct, and there is no need to mark the i-th experimental supplies in red on the experimental platform interface of the student-side display device;

[0088] If δ i ≠0 means that the placement of the i-th experimental supplies is incorrect, and the i-th experimental supplies need to be marked in red on the experimental platform interface of the student-side display device.

[0089] In this embodiment, whether the student's experiment is correct is analyzed based on the location of the experimental supplies. If incorrect, the location of the incorrect experimental supplies will be marked in red on the experimental platform interface of the student-side display device, thereby reminding the student of the experimental error. Therefore, whether the student's experiment is accurate can be judged based on the location of the experimental supplies, thereby improving the automation capability of remote experiments.

[0090] It should be noted that, in practical applications, all possible implementation methods described above can be combined in any manner to form possible embodiments of the present application, which will not be described one by one here.
