[0036] Specifically, in the interactive multimedia display system, the displacement detection device is a rangefinder capable of emitting infrared rays to the counterweight.

[0037] The technical solution adopted by the present invention to solve the second technical problem is: a network-based control method for the interactive multimedia display system, characterized by comprising the following steps:

[0038] Step 1: The displacement detection device detects the distance moved by the counterweight block in the control device and sends the detected counterweight block displacement data to the controller;

[0039] Step 2: The controller makes a judgment based on the received counterweight displacement data:

[0040] When the displacement data of the counterweight reaches a preset displacement value, the controller instructs the display screen corresponding to the preset displacement value to call the corresponding multimedia data in the data memory, and the process proceeds to step 3; otherwise, the controller does not send a command to any display screen; wherein each display screen corresponds to a preset displacement value, and there is a one-to-one correspondence between each preset displacement value and the multimedia data in the data memory;

[0041] In step 3, the display screen displays the multimedia data it has called, and the audio playing device plays the audio data contained in the multimedia data.

[0042] The technical solution adopted by the present invention to solve the third technical problem is: a network-based control method for the interactive multimedia display system, characterized by comprising the following steps:

[0043] Step a1, the human infrared sensor starts detecting infrared signals from the human body;

[0044] Step a2: When the human infrared sensor detects a human infrared signal, the human infrared sensor sends the detection result to the controller; otherwise, the human infrared sensor does not send any information to the controller;

[0045] Step a3, the controller instructs the displacement detection device to start detection;

[0046] Step a4, the displacement detection device detects the distance moved by the counterweight block in the control device, and sends the detected counterweight block displacement data to the controller;

[0047] Step a5: The controller makes a judgment based on the received counterweight displacement data:

[0048] When the displacement data of the counterweight reaches a preset displacement value, the controller instructs the display screen corresponding to the preset displacement value to call the corresponding multimedia data in the data memory, and the process proceeds to step a6. Otherwise, the controller does not send the command to any display screen. Each display screen corresponds to a preset displacement value, and there is a one-to-one correspondence between each preset displacement value and the multimedia data in the data memory.

[0049] In step a6, the controller analyzes the multimedia data called by the display screen and processes the data according to the analysis result:

[0050] When the content corresponding to the multimedia data contains an environmental scene, go to step a8; otherwise, go to step a7;

[0051] Step a7, the display screen displays the called multimedia data, and the audio playing device plays the audio data contained in the multimedia data;

[0052] In step a8, the controller instructs the device corresponding to the environmental scene to start working and receives data sent by the environment-related sensor corresponding to the environmental scene; wherein the device corresponding to the environmental scene is at least one of a light-emitting device, a smoke-releasing device, a blasting device, a heating device, or a cooling device; and correspondingly, the environment-related sensor corresponding to the environmental scene is at least one of a light intensity sensor, a wind speed sensor, a temperature sensor, or a humidity sensor;

[0053] In step a9, the controller determines the current environment of the user based on the received sensor data related to the environment:

[0054] When the data of the environment-related sensors all match the environmental data corresponding to the environmental scene, the controller does not process them; otherwise, the controller commands the device corresponding to the environmental scene to adjust its working state so that the data of the environment-related sensors after adjustment all match the environmental data corresponding to the environmental scene.

[0055] Further improved, in the network-based control method of the interactive multimedia display system, before transitioning from step a2 to step a3, the method further includes:

[0056] Step a21, the audio collection device collects external voice data and sends the voice data to the audio recognition device;

[0057] Step a22: If the audio recognition device determines that the voice data is consistent with a control instruction pre-stored in the audio recognition device, the audio recognition device sends the control instruction to the controller and the process proceeds to step a23; otherwise, the audio recognition device does not perform any processing and the process proceeds to step a24;

[0058] Step a23, the controller instructs the device corresponding to the control instruction to execute the action corresponding to the control instruction, and then proceeds to step a24;

[0059] Step a24: the gesture recognition device judges the gesture of the person appearing at the human-computer interaction device:

[0060] When the person's gesture is consistent with the control instruction pre-stored in the gesture recognition device, the gesture recognition device sends the control instruction to the controller and the process goes to step a25; otherwise, the gesture recognition device does not perform any processing and the process goes to step a26;

[0061] Step a25, the controller instructs the device corresponding to the control instruction to execute the action corresponding to the control instruction, and then proceeds to step a26;

[0062] In step a26, the controller instructs the camera to start recording and saves the recorded data into a data storage device.

[0063] As a further improvement, in the network-based control method of the interactive multimedia display system, the controller receives an external input instruction sent by the input device of the human-computer interaction device, and commands the device corresponding to the external input instruction to perform the action corresponding to the external input instruction.

[0064] Further improved, in the network-based control method of the interactive multimedia display system, after step a9, the method further includes:

[0065] Step a10, the Bluetooth device of the human-computer interaction device receives a pairing communication request sent by the user's mobile terminal;

[0066] Step a11: After the human-computer interaction device establishes Bluetooth communication with the user's mobile terminal, the human-computer interaction device receives the data to be displayed sent by the mobile terminal;

[0067] Step a12, the human-computer interaction device sends the data to be displayed to the controller through the switch device;

[0068] In step a13, the controller determines the legitimacy of the data to be displayed:

[0069] When the data to be displayed is legal data, the controller randomly commands a display screen in an idle state to display the data to be displayed; otherwise, the controller does not process the data and does not feed back any information to the user's mobile terminal.

[0070] Compared with the prior art, the advantages of the present invention are:

[0071] First, the interactive multimedia display system of the present invention is provided with a control device having a counterweight and an operating rod. The displacement detection device sends displacement detection data of the counterweight to the controller for processing. The controller then commands the display screen to display corresponding multimedia data based on the displacement of the counterweight, thus achieving the control experience of the multimedia display system as an ordinary user.

[0072] Secondly, by setting up interactive machine equipment, the displacement detection device, controller and human-computer interaction equipment establish data interaction based on the local area network, making the structure of the entire multimedia display system simpler and wiring and maintenance more convenient;

[0073] Again, by setting different environment-related execution devices (such as light-emitting devices, smoke release devices, blowing devices, heating devices and cooling devices) and sensors for detecting environmental parameters (such as light intensity sensors, wind speed sensors, temperature sensors and humidity sensors), the controller can adjust the operation of the corresponding above-mentioned execution devices according to the data sent by such sensors, so that the parameters of the user's current environment meet the environmental scene corresponding to the multimedia data currently displayed on the display screen, satisfying the user's on-site personal experience of the displayed multimedia data, enriching the sensory experience presented to the user by the multimedia display system, and making it more fun.

[0109] See also Figure 6 As shown, this embodiment provides a network-based control method for the above-mentioned interactive multimedia display system. Figures 1 to 5 The network-based control method of the interactive multimedia display system includes the following steps:

[0110] Step 1: The displacement detection device 105 detects the distance moved by the counterweight 1041 in the control device 104 and sends the detected displacement data of the counterweight to the controller 102;

[0111] Step 2: The controller 102 makes a judgment based on the received displacement data of the counterweight:

[0112] When the displacement data of the counterweight reaches the preset displacement value, it indicates that the counterweight 1041 has been moved by the user to the position where the multimedia data should be played. At this time, the controller 102 instructs the display screen 1011 corresponding to the preset displacement value to call the corresponding multimedia data in the data storage 108, and the process goes to step 3. Otherwise, the controller 102 does not send the command to any display screen. Each display screen corresponds to a preset displacement value, and there is a one-to-one correspondence between each preset displacement value and the multimedia data in the data storage 108.

[0113] In step 3, the display screen 1011 displays the retrieved multimedia data, and the audio playback device 111 plays the audio data contained in the multimedia data.

[0114] Furthermore, this embodiment also provides another network-based control method for the above-mentioned interactive multimedia display system. Figure 7 , and combined with Figures 1 to 5 The network-based control method of the interactive multimedia display system includes the following steps:

[0115] Step a1: the human infrared sensor 112 starts detecting infrared signals from the human body;

[0116] Step a2: When the human infrared sensor 112 detects a human infrared signal, it indicates that a person is walking at the human-computer interaction device 107, and the human infrared sensor 112 sends the detection result to the controller 102; otherwise, the human infrared sensor 112 does not send any information to the controller 102;

[0117] Step a3: the controller 102 instructs the displacement detection device 105 to start detection;

[0118] Step a4: the displacement detection device 105 detects the distance moved by the counterweight 1041 in the control device 104 and sends the detected displacement data of the counterweight to the controller 102;

[0119] Step a5: The controller 102 makes a judgment based on the received counterweight displacement data:

[0120] When the displacement data of the counterweight reaches the preset displacement value, it indicates that the user has moved the counterweight 1041 to the position where the multimedia data should be played. The controller 102 instructs the display screen 10111 corresponding to the preset displacement value to call the corresponding multimedia data in the data memory 108, and the process proceeds to step a6. Otherwise, the controller 108 does not send the command to any display screen. Each display screen corresponds to a preset displacement value, and there is a one-to-one correspondence between each preset displacement value and the multimedia data in the data memory 108.

[0121] In step a6, the controller 102 analyzes the multimedia data called by the display screen 1011 and processes the data according to the analysis result:

[0122] When the content corresponding to the multimedia data contains an environmental scene, go to step a8; otherwise, go to step a7;

[0123] Step a7: the display screen 1011 displays the retrieved multimedia data, and the audio playback device 111 plays the audio data contained in the multimedia data;

[0124] In step a8, the controller 102 instructs the device corresponding to the environmental scene to start working and receives data sent by the environment-related sensor corresponding to the environmental scene; wherein the device corresponding to the environmental scene is at least one of the light-emitting device 110, the smoke release device 118, the air blowing device 119, the heating device 120, or the cooling device 121; correspondingly, the environment-related sensor corresponding to the environmental scene is at least one of the light intensity sensor 114, the wind speed sensor 117, the temperature sensor 115, or the humidity sensor 116;

[0125] In step a9, the controller 102 determines the current environment of the user based on the received sensor data related to the environment:

[0126] When the data of the environment-related sensors all match the environmental data corresponding to the environmental scene, the controller does not process them; otherwise, the controller 102 commands the device corresponding to the environmental scene to adjust the working state so that the data of the environment-related sensors after adjustment all match the environmental data corresponding to the environmental scene.

[0127] The following explanation is given for step a9. Assuming that the multimedia data is video data after analysis by the controller and contains a scene about wind, then the controller will command the blower to start the blowing operation to blow out wind. If the controller determines that the wind speed sensor detects that the current wind speed has reached the wind speed value required by the windy scene in the multimedia data, the controller commands the blower to maintain the current state; if the controller determines that the wind speed sensor detects that the current wind speed deviates from the wind speed value range required by the windy scene in the multimedia data, the controller commands the blower to reduce or increase the blowing power so that the wind speed detected by the wind speed sensor is within the required wind speed value range.

[0128] By setting different environment-related execution devices (such as light-emitting devices, smoke release devices, blowing devices, heating devices and cooling devices) and sensors for detecting environmental parameters (such as light intensity sensors, wind speed sensors, temperature sensors and humidity sensors), the controller can adjust the operation of the corresponding above-mentioned execution devices according to the data sent by such sensors, so that the parameters of the user's current environment meet the environmental scene corresponding to the multimedia data currently displayed on the display screen, satisfying the user's on-site personal experience of the displayed multimedia data, enriching the sensory experience presented to the user by the multimedia display system, and making it more interesting.

[0129] Of course, as a link for realizing interaction between the user and the interactive multimedia display system, the network-based control method of the interactive multimedia display system further includes the following steps before transitioning from step a2 to step a3:

[0130] Step a21, the audio collection device 123 collects external voice data and sends the voice data to the audio recognition device 124;

[0131] In step a22, if the audio recognition device 124 determines that the voice data is consistent with the control instruction pre-stored in the audio recognition device, the audio recognition device 124 sends the control instruction to the controller 102 and the process proceeds to step a23; otherwise, the audio recognition device 124 does not perform any processing and the process proceeds to step a24;

[0132] In step a23, the controller 102 instructs the device corresponding to the control instruction to execute the action corresponding to the control instruction, and then proceeds to step a24;

[0133] In step a24, the gesture recognition device 113 determines the gesture of the person appearing at the human-computer interaction device 107:

[0134] When the person's gesture is consistent with the control instruction pre-stored in the gesture recognition device, the gesture recognition device 113 sends the control instruction to the controller 102 and the process proceeds to step a25; otherwise, the gesture recognition device 113 does not perform any processing and the process proceeds to step a26;

[0135] In step a25, the controller 102 instructs the device corresponding to the control instruction to execute the action corresponding to the control instruction, and then proceeds to step a26;

[0136] In step a26 , the controller 102 instructs the camera 122 to start recording and save the recorded data into the data storage 108 .

[0137] Of course, the controller 102 may also receive an external input instruction sent by the input device 1071 of the human-computer interaction device 107 , and instruct the device corresponding to the external input instruction to execute the action corresponding to the external input instruction.

[0138] In order to further enhance the user's participation experience, the network-based control method of the interactive multimedia display system of this embodiment further includes, after step a9:

[0139] Step a10: the Bluetooth device 1072 of the human-computer interaction device 107 receives a pairing communication request sent by the user's mobile terminal;

[0140] Step a11: After the human-computer interaction device 107 establishes Bluetooth communication with the user's mobile terminal, the human-computer interaction device 107 receives the data to be displayed sent by the mobile terminal;

[0141] Step a12: the human-computer interaction device 107 sends the data to be displayed to the controller 102 via the switch device 106;

[0142] In step a13, the controller 102 determines the legitimacy of the data to be displayed:

[0143] When the data to be displayed is legal data, the controller 102 randomly commands the display screen 1011 in an idle state to display the data to be displayed; otherwise, the controller 102 does not process the data and does not feed back any information to the user's mobile terminal.
