In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0032] In the related technology, when conducting interactive interactions with exhibits, it is necessary to rely on various physical trigger devices. Specifically, different physical trigger detection devices are used to detect the position of the exhibitors, the distance from the target object, the sound, the action, the image and other information to trigger different physical response devices, such as audio playback, video playback, starting motor-driven mechanical equipment, turning on lighting equipment, etc.

[0033] However, different physical trigger devices generally come from different manufacturers, and there is no industry-wide development method, which results in differences in the installation methods and control interfaces required for different physical trigger devices. In scenarios with many physical trigger devices, installers are required to install and develop controls for each physical trigger device separately, which makes development, installation, and maintenance more difficult, and creates a burden of repeated development for developers, and requires a high level of professionalism for installation and maintenance personnel.

[0034] Moreover, when controlling after installation, it is easy to cause interference or asynchrony problems between different physical trigger devices, resulting in poor control stability and high error rate.

[0035] In order to solve the problems of low integration and high difficulty in unified control in the physical trigger system of the exhibition in the related art, which leads to unstable system control, the embodiment of the utility model provides a physical trigger system for the exhibition. Figures 1 to 5 As shown, the present application provides a physical triggering system for exhibitions, including: a controller 1, an expander 2, and a physical triggering device 3.

[0036] The controller 1 includes a control chip 11, a network interface 12, and an expansion port 13; the expander 2 includes a signal input port 21 and a signal output port 22, and the expander 2 is connected to the control chip 11 through the expansion port 13; the physical trigger device 3 is connected to the controller 1, and the physical trigger device 3 includes a physical trigger detection device 31 and a physical response device 32; the physical trigger detection device 31 is connected to the signal input port 21, and the physical response device 32 is connected to the signal output port 22; the network interface 12 is connected to the control chip 11, and the control chip 11 is connected to the network communication device and the host computer through the network interface 12, and the host computer is used to edit the physical trigger control program in the control chip 11, wherein the physical trigger control program is used to control the physical trigger device connected to the controller.

[0037] Multiple physical trigger devices can be connected through the controller and the expander. The physical trigger devices include physical trigger detection devices and physical response devices. That is, multiple physical trigger devices can be integrated and controlled uniformly through the control chip of the controller, which improves the overall stability of the system. The network interface is used to connect to the host computer, and the physical trigger control programs of the multiple connected physical trigger devices are uniformly developed and maintained. Multiple physical trigger devices from different manufacturers are developed in the same development environment, which improves development efficiency, reduces development difficulty, and better meets user needs and reduces usage difficulty.

[0038] The control chip receives the detection data of the physical trigger detection device through the signal input port to support different actions of the physical trigger control program during execution, and uses the control device to control different physical response devices to respond, thereby stably and safely realizing the actions of multiple physical trigger detection devices and physical response devices, effectively completing the integration of multiple different physical trigger devices, improving the system integration and work stability, and providing a basis for a unified development environment. This solves the problem of low integration and high difficulty in unified control of the exhibition physical trigger system in related technologies, which in turn causes unstable system control, and achieves the technical effect of improving system integration, reducing the difficulty of unified control and development, and improving the stability of system control.

[0039] The controller 1 may include a housing, a printed circuit board PCB, and the control chip 11, the network interface 12, and the expansion port 13 may be integrated on the PCB. The expander 2 may include a housing, a printed circuit board PCB, and the signal input port 21 and the signal output port 22 may be integrated on the PCB. The expander 2 is connected to the control chip 11 of the controller 1 via the expansion port 13.

[0040] Expander 2 can set up or expand the interfaces of various different physical trigger detection devices according to needs, so that physical trigger devices from various different manufacturers can be integrated into one control system. Controller 1 and expander 2 can be used as a complete set of products to build a physical trigger system for exhibitions in conjunction with existing physical trigger devices, and physical trigger devices from different manufacturers can be uniformly developed and controlled, thereby improving development efficiency, reducing the difficulty of development and maintenance, and improving control stability.

[0041] A controller 1 can be connected to one or more expanders 2 to set the signal input port 21 and the signal output port 22 as required, and then connect and integrate physical trigger detection equipment as required.

[0042] The above-mentioned physical triggering device is also a device related to physical triggering. Physical triggering is triggered by physical parameters such as sound, light, heat, electricity, etc., and performs a triggering method for physical responses such as sound, light, heat, electricity, etc. For example, the pressure sensor detects the user's pressing on the target area, and automatically plays the audio, video and supporting lighting equipment corresponding to the target area. The triggering parameter is pressure, and the response method includes playing sound, video (in the form of light) and light.

[0043] The physical trigger device 3 can be divided into a physical trigger detection device 31 that transmits data to the controller and a physical response device 32 that receives controller instructions and performs actions according to the data transmission direction of the controller. The physical trigger detection device 31 is mainly used to detect the physical parameters of the exhibition object and can be a sensor, detector, etc.

[0044] The controller 1 includes a control chip 11 and a network interface 12. The control chip 11 is a processor mainly used for program control and data processing. Its main functions include receiving and processing the detection data of the above-mentioned physical trigger detection device 31, determining a specific response method according to the detection data according to a predetermined physical trigger control program, generating a response instruction, and controlling the corresponding physical response device 32 to perform an action response according to the response instruction.

[0045] Expansion port 13 is mainly used to expand the connection port of controller 1. Due to the need to integrate and control multiple physical trigger devices, the port of controller 1 is limited. In order to adapt to the usage scenarios with large changes in quantity, the controller and expander are set separately, and the expander 2 is connected to the expansion port 13 of controller 1 as needed to realize the port expansion of controller 1.

[0046] The above-mentioned network interface 12 provides a network connection for the control chip 11. The control chip 11 can be connected to the network communication device through the network interface 12, and then connected to the host computer 3. The physical trigger control program in the control chip 11 can be edited through the host computer 3. The physical trigger control program is used to control the physical trigger device 3 connected to the controller 1.

[0047] It should be noted that the above physical trigger control program faces multiple or all physical trigger devices 3 connected to the controller 1 and the expander 2. The physical trigger devices 3 connected to the controller 1 and the expander 2 can be uniformly developed and controlled through the editing of the physical trigger program by the host computer, thereby realizing unified development and control of physical trigger devices from different manufacturers and improving the integration of system control.

[0048] In other embodiments, the controller 1 may also be provided with a small number of signal input interfaces and signal output interfaces to meet the purpose of using the controller 1 alone.

[0049] The signal input port 21 is connected to the physical trigger detection device 31, and the signal input port 21 is used to transmit the detection data of the physical trigger detection device 31 to the control chip 11, so that the control chip 11 executes the physical trigger control program according to the detection data. The signal input port 22 is connected to the physical trigger detection device 31, and the signal input port 21 is used to transmit the detection data of the physical trigger detection device 31 to the control chip 11, so that the control chip 11 executes the physical trigger control program according to the detection data.

[0050] It should be noted that there may be multiple signal input ports 21, and different signal input ports 21 may be applicable to different physical trigger detection devices 31, so as to facilitate the connection of various types of physical trigger detection devices 31. There may also be multiple signal output ports 22, and different signal output ports 22 may be applicable to different physical response devices 32, so as to facilitate the connection of various types of physical response devices 32.

[0051] As an optional embodiment, the controller 1 also includes a control device 14; the control device 14 is connected to the control chip 11, and the control device 14 is also connected to the physical response device 32; the control device 14 is used to control the physical response device 32 according to the instructions of the control chip 11.

[0052] The controller 1 also includes a control device 14, which is connected to the control chip 11. The control device 14 is also connected to the physical response device 32. The control device 14 is used to control the physical response device 32 according to the instructions of the control chip 11 when the control chip 11 executes a physical trigger control program and the physical response device 32 needs to be controlled.

[0053] The control device 14 can control a variety of physical response devices 32, and it can also include auxiliary control devices, such as relays, switches, motor drive devices, etc. The main purpose is to control the corresponding physical response device 32 to respond according to the instructions of the control chip 11. In this way, physical trigger devices of multiple different manufacturers can be uniformly and effectively controlled, which improves the stability and reliability of system control.

[0054] As an optional embodiment, it also includes: a multimedia server; the multimedia server is connected to the controller and is used to provide multimedia storage services; the multimedia server is also provided with a video playback port for connecting to a video playback device to provide video playback services.

[0055] Since the controller 1 itself does not have a large memory device, for multimedia resources with large data volumes, it is necessary to use external storage services. The above-mentioned multimedia server is mainly used to store multimedia. When the controller needs to play the multimedia data, the multimedia data is sent to the video playback device through the video playback port HDMI for playback according to the instructions of the controller.

[0056] Thus, the demand for multimedia playback in the physical trigger system is realized. Compared with the built-in large memory storage device, the multimedia server is lower in cost and more convenient to use.

[0057] As an optional embodiment, when there are multiple multimedia servers, the exhibition physical trigger system also includes: a central control server; the central control server is arranged between the controller and the multimedia server, and the central control server is connected to multiple multimedia servers, and is used to control the corresponding multimedia server to respond to multimedia data according to the instructions of the control chip 11.

[0058] In the case of a complex physical trigger system, there may be multiple multimedia servers. In this case, it is easy to make mistakes and have poor stability if the control chip directly controls multiple multimedia servers. Therefore, a central control server can be set between multiple media servers and the controller to control multiple multimedia servers according to the instructions of the controller, thereby improving the stability and reliability of system control.

[0059] As an optional embodiment, the controller 1 also includes an external storage interface; the external storage interface is used to install an external storage device, the external storage device is connected to the control chip 11 through the external storage interface, and the external storage device is used to provide audio data storage services for the control chip 11.

[0060] Since audio playback is a more common response method, and the amount of audio data is generally small, only a smaller memory is required. Therefore, the controller of this embodiment can also be provided with an external storage interface, such as a memory card slot, to insert a memory card as a storage device for storing audio data.

[0061] As an optional embodiment, the controller 1 also includes an audio playback device 15; the audio playback device 15 is connected to the control chip, and the audio playback device is also connected to an external storage device. The audio playback device 15 is used to control the corresponding audio data to play according to the instructions of the control chip 11.

[0062] The audio playback device can be a speaker or built into the controller to facilitate sound playback. An external audio playback port can also be set, such as a headphone interface, a speaker interface, etc., to connect external devices to improve the audio playback effect.

[0063] The built-in external storage can also store images simply for easy use. The built-in audio playback device can make the audio response faster, broaden the application scenarios of the controller, and improve the convenience of using the controller.

[0064] As an optional embodiment, the controller 1 also includes an audio interface; the audio interface is used to connect an external audio device, and the external audio device is used to play audio data; there are multiple audio interfaces, and the multiple audio interfaces correspond to multiple different external audio devices.

[0065] Taking into account different audio playback scenarios, different audio playback devices may be used. Multiple audio interfaces can be set to connect external audio devices that need to be connected to meet diverse audio playback needs.

[0066] As an optional embodiment, the expander also includes: a splitter 23, an input / output IO interface 24; the input end of the splitter 23 is connected to the controller, the input / output IO interface 24 is connected to the output end of the splitter 23, and the input / output IO interface 24 is respectively connected to the signal input port 21 and the signal output port 22; there are multiple signal input ports 21 and signal output ports 22.

[0067] Since the controller of this embodiment needs to connect to multiple physical trigger devices, the number of ports on the controller may be limited, and may not be sufficient in some cases. To this end, an expander can be used to provide more expansion ports for the control chip of the controller by using a splitter and an input / output interface, so as to connect more physical trigger devices.

[0068] A plurality of the above expanders can be connected to the controller at the same time to realize multi-level expansion of the expansion port, thereby improving the application range of the controller and the expander.

[0069] As an optional embodiment, the physical trigger detection device 31 includes at least one of the following: a sound detection device, an image detection device, an infrared detection device, and a pressure detection device;

[0070] As an optional embodiment, the physical response device 32 includes at least one of the following: an audio playback device, an image playback device, a motor response device, and a switch response device.

[0071] The physical trigger detection device includes at least one of the following: sound detection device, image detection device, infrared detection device, pressure detection device; the physical response device includes at least one of the following: audio playback device, image playback device, motor response device, switch response device.

[0072] The above-mentioned sound detection equipment can be a detection equipment using sound as a medium, such as a microphone or an ultrasonic detector. The image detection equipment can be a detection equipment for collecting images, such as a camera or a still camera. The infrared detection equipment can be a device for detecting using infrared light as a medium, such as an infrared detector or a thermal image detector. The pressure detection equipment can be a detection equipment for detecting pressure, such as a touch detection equipment or a pressure-sensitive sensor.

[0073] The audio playback device may be a device that plays sound, such as headphones and speakers. The image playback device may be a device that plays images and videos, such as a display and a projector. The motor response device may be a device that drives a component by a motor to make the component move mechanically, so that the displacement and distance between components change, thereby producing different overall states, such as a fan, a vibration table, and other dynamic devices. The switch response device may be a device controlled by a switch, such as a lighting device.

[0074] It should be noted that the above-mentioned physical trigger detection devices and physical response devices are only a feasible basis for classification description from different angles. There may be overlaps between different physical trigger detection devices or different physical response devices. For example, a fan device can be classified as a motor response device or a switch response device. This embodiment is not absolutely limited to this. Other devices that meet the use requirements of this embodiment can also be classified as other types as physical trigger detection devices or physical response devices.

[0075] It should be noted that this embodiment also provides an optional implementation, which is described in detail below.

[0076] This embodiment provides an integrated physical interaction triggering system. Figure 2 A schematic diagram of a physical triggering system of a controller and an expander according to an embodiment of the present utility model is shown in FIG. Figure 2 As shown, its controller consists of a controller (i-box) and an expander (box+). The controller (i-box) uses a unified Arduino development board as a platform, uses a NANO chip made of an ATMEL328P microcontroller to process data, integrates Ethernet, POE power supply, serial interface communication, and MP3 audio playback, and independently designs electrical schematics, PCB boards, and control programs, which can realize the connection and interaction between multiple exhibits and the control of multiple interactive modes of a single exhibit. The expansion board (box+) decomposes the two network cable IO transmission ports integrated in the core board (i-box) into 10 groups of commonly used pin-type ports to meet different needs. The above expansion board is also the printed circuit board PCB of the expander (box+), and the core board (i-box) is also the printed circuit board PCB of the controller (i-box).

[0077] Specifically, Ethernet is a computer LAN networking technology. It is also the most commonly used LAN technology. The IEEE 802.3 standard of the IEEE organization has formulated the technical standards for Ethernet, which stipulates the content including the physical layer connection, electronic signals and media access layer protocols. Ethernet is the most commonly used LAN technology, replacing other LAN technologies such as Token Ring, FDDI and ARCNET.

[0078] In the above-mentioned POE power supply technology, POE (Power Over Ethernet) refers to a technology that can provide DC power to some IP-based terminals (such as IP phones, wireless LAN access points AP, network cameras, etc.) while transmitting data signals without making any changes to the existing Ethernet Cat.5 wiring infrastructure.

[0079] A complete POE system consists of two parts: the power sourcing equipment (PSE) and the power device (PD). The POE switch is the PSE device, and the wireless access point AP or surveillance camera is the PD device. The two establish information about the connection status, device type, power consumption level, etc. of the power device PD based on the IEEE802.3af standard, and based on this, the PSE supplies power to the PD through Ethernet.

[0080] Preferably, the present embodiment utilizes the IEEE 802.3af (POE) standard.

[0081] The above serial interface is a device that can convert the parallel data characters received from the control chip CPU into a continuous serial data stream and send it out, and at the same time can convert the received serial data stream into parallel data characters to supply to the CPU. The circuit that generally performs this function is called a serial interface circuit.

[0082] As one of the computer communication methods, serial communication mainly plays the role of data transmission between the host and peripherals and between the hosts. Serial communication has the characteristics of fewer transmission lines and low cost. It is mainly suitable for short-distance human-computer exchange, real-time monitoring and other system communications. With the help of the existing telephone network, long-distance transmission can also be achieved. Therefore, the serial communication interface is a commonly used interface in computer systems.

[0083] In this embodiment, the ATMEL328P microcontroller is used as the control chip 11, and the Atmel ATmega328 8-bit The microcontroller is a high-performance RISC-based device that combines 32KB ISP flash memory, simultaneous read and write capabilities, 1KB EEPROM, 2KBSRAM, 23 general-purpose I / O lines, 32 general-purpose working registers, and serial programmable USART. The Atmel ATmega328MCU can complete powerful instructions in a single clock cycle, allowing the device to achieve a throughput close to 1MIPS / MHz while balancing power consumption and processing speed. These Atmel MCUs are designed for industrial automation, residential and building automation.

[0084] PCB printed circuit board technology, PCB (Printed Circuit Board) printed board, also called printed circuit board, printed circuit board. Multilayer printed board refers to a printed board with more than two layers. It is composed of connecting wires on several layers of insulating substrates and pads for assembling and welding electronic components. It has the function of conducting each layer of circuits and insulating each other.

[0085] Shell industrial design: The team used Rhino to design and model the shell and overall structure of the utility model. On the basis of achieving functions and saving space, the appearance is optimized to make it beautiful, simple, compact and easy to use. The shell is divided into three layers, namely the bottom plane, the middle support and the top cover. The three parts are assembled with nuts and screws. The current version uses 3D printing technology to realize the production of the shell.

[0087] The application scenario is the exhibition display projects of various exhibition halls. Once put into use, a single product can achieve the effect of receiving multiple sensor signals, controlling multiple devices and playing MP3 audio. The utility model and use of this device that can control multiple devices without relying on computers and servers in the exhibition hall effectively improves the efficiency of exhibition layout and reduces the cost of exhibition construction. This method of achieving multiple control through equipment and reducing costs and increasing efficiency should be protected.

[0088] like Figure 3As shown, the controller (i-box) uses ATMEL328P microcontroller, W5100S embedded Ethernet controller, various interfaces, resistors, capacitors and voltage regulators, and other components, and uses PCB printed multilayer board technology to make integrated circuits and install them as interactive product boxes.

[0090] The JQ8400 voice module uses the SOC solution, integrating a 16-bit MCU and a digital signal processor ADSP specifically for audio decoding. It uses hard decoding to ensure the stability and sound quality of the system. The compact size better meets the needs of embedding in other products. The module uses SPI-flash to replace the voice content, eliminating the trouble of installing a host computer to replace the voice of the traditional voice chip. SPI FLASH directly simulates the U disk to copy files, which is very convenient.

[0091] This implementation implements a series of functions including POE power supply, serial signal transmission, network communication, storage, simultaneous identification and processing of multiple sensor signals, audio control playback, and control of 220V voltage on and off. The main control box and the switch are connected via a network cable to realize the power supply of the controller.

This method of achieving multiple control and reducing costs and increasing efficiency through equipment should be protected.

[0094] This embodiment carries out the industrial design of the shell. The shell is divided into three layers, namely the bottom plane, the middle support and the top cover. The three parts are assembled by nut inserts and screws. Such a design effectively increases the stability and safety of the hardware combination, facilitates installation and transportation, and protects the hardware.

[0095] This implementation uses an ATMEL328P microcontroller, a W5100S embedded Ethernet controller, various interfaces, resistors, capacitors, and voltage regulators, and uses PCB printed multilayer board technology to make an integrated circuit and install it as an interactive product box. This implementation is divided into two parts, namely the main control box (i-box) and the expander (box). Figure 2-4 As shown, the main control box contains the main circuit board, including POE power supply, two RJ45 expansion interfaces, DC12V power supply interface, speaker, 3.5mm audio interface, TF card slot, and relay.

Figure 6-1 U2 is the above Ethernet controller, which is connected to the POE power supply port RJ2 and the POE power supply chip U8. The POE power supply chip U8 is connected to the backup external power socket DC1, the switching regulator and the output voltage terminal.

[0098] In the early stage of product delivery, the customer puts forward specific interactive exhibit requirements. The developer debugs the code and connects the sensor hardware. After assembly, it is delivered to the customer together with the product manual. After receiving the finished product, the customer only needs to connect the network cable according to the instructions, fix the main control box and expander (if necessary) and the sensor hardware to complete the function construction.

[0099] The program of this embodiment uses embedded programming. The Arduino IDE platform is used for program development. During testing and use, the Arduino IDE is also used to modify and add items to the program.

[0100] This embodiment can also be connected to a computer and transmit signals.

[0103] Unifying development standards in the process and developing content based on the product saves the team the hardware R&D cycle and allows them to focus on designing physical interactive content. Different teams can develop customized content in a unified environment, which can also better control costs, and management and maintenance are relatively unified.

[0104] The development team uniformly develops in the Arduino environment, connecting the corresponding sensors with the output peripherals to achieve interaction between the sensors and the devices.

[0105] The controller and expander of this embodiment have a high degree of integration for physical interactive elements, and can expand up to ten trigger elements at the same time, and can edit the logic of each other. The triggering of interactive elements can be linked with many devices, such as lights, smoke machines, motors, etc., and the combination of each other can evolve into more creative works, allowing the experiencer to experience a multi-level interactive experience in an immersive space.

[0106] When deployed on-site, a wired or wireless network can be used for connection, and the device can be placed in the front-end display item. When a large amount of computing needs to be interacted with multimedia content, it is necessary to network with the media server in the computer room. The deployment is more flexible according to the project and site requirements.

[0107] Integrated hardware and convenient equipment deployment provide buyers with a more efficient purchasing experience; a unified development environment and multiple combinations of interactive components provide the development team with efficient and stable hardware support; a combination of varied experience scenarios and more immersive experience projects provide the audience with an all-encompassing interactive experience.

[0108] Figure 5 A flow chart of a control method of a physical trigger system for an exhibition according to an embodiment of the utility model, such as Figure 5 As shown, the embodiment of the utility model further provides a control method of the exhibition physical trigger system. Optionally, the control method of the exhibition physical trigger system provided by the embodiment of the utility model can be used in the exhibition physical trigger system provided by the above embodiment. The method comprises the following steps:

[0109] Step S501, writing a physical trigger program into a control chip of a controller through a host computer and a network interface, wherein the physical trigger program is used to control a physical trigger device to work according to a predetermined trigger condition, the physical trigger device is connected to the controller, and the physical trigger device includes a physical trigger detection device and a physical response device;

[0110] Step S502, receiving detection data collected by a physical trigger detection device through a control chip of the controller;

[0111] Step S503, determining whether to control the corresponding physical response device to work according to the detection data and the physical trigger program;

[0112] Step S504, when the physical triggering program determines to control the corresponding physical response device to work, a command is sent to the control device, and the control device controls the corresponding physical response device to work.

[0113] The control method of the exhibition physical trigger system provided in this embodiment can connect multiple physical trigger devices through the controller, and the physical trigger devices include physical trigger detection devices and physical response devices, that is, multiple physical trigger devices can be integrated, integrated together, and uniformly controlled through the control chip of the controller, thereby improving the overall stability of the system. The network interface is used to connect to the host computer, and the physical trigger control programs of the multiple connected physical trigger devices are uniformly developed and maintained, and multiple physical trigger devices from different manufacturers are developed in the same development environment, thereby improving development efficiency, reducing development difficulty, and better meeting user usage requirements and reducing usage difficulty.

[0114] The control chip receives the detection data of the physical trigger detection device through the signal input port to support different actions of the physical trigger control program during execution, and uses the control device to control different physical response devices to respond, thereby stably and safely realizing the actions of multiple physical trigger detection devices and physical response devices, effectively completing the integration of multiple different physical trigger devices, improving the system integration and work stability, and providing a basis for a unified development environment. This solves the problem of low integration and high difficulty in unified control of the exhibition physical trigger system in related technologies, which in turn causes unstable system control, and achieves the technical effect of improving system integration, reducing the difficulty of unified control and development, and improving the stability of system control.

[0115] The executor of the above steps can be the control chip of the controller, which is a processor mainly used for program control and data processing. Its main functions include receiving and processing the detection data of the above-mentioned physical trigger detection device, determining the specific response method according to the detection data according to a predetermined physical trigger control program, generating a response instruction, and sending the response instruction to the control device to control the corresponding physical response device to respond to the action.

[0116] As an optional embodiment, it also includes: when it is determined to control the corresponding physical response device to perform multimedia playback, sending a multimedia playback instruction to the multimedia server; obtaining the multimedia to be played through the multimedia server; and sending the obtained multimedia to be played to the multimedia playback device for playback through the multimedia interface of the multimedia server.

[0117] For multimedia resources with large data volume, external storage services are required. The above-mentioned multimedia server is mainly used to store multimedia. When the controller needs to play multimedia data, the multimedia data is sent to the video playback device through the video playback port, such as the HDMI port, for playback according to the controller's instructions. This meets the demand for multimedia playback in the physical trigger system. Compared with the built-in large memory storage device, the multimedia server is lower in cost and more convenient to use.

[0118] As an optional embodiment, in the case of multiple multimedia servers, when it is determined to control the corresponding physical response device to perform multimedia playback, sending a multimedia playback instruction to the multimedia server includes: when the physical trigger program determines to control the corresponding physical response device to perform multimedia playback, sending an instruction to the central control server to play the target multimedia through the target multimedia playback device; searching for the multimedia server where the target multimedia is located through the central control server, and obtaining the target multimedia; and sending the target multimedia to the multimedia playback device through the multimedia interface for playback.

[0119] Directly controlling multiple multimedia servers by the control chip is prone to errors and has poor stability. Therefore, a central control server can be set between multiple media servers and the controller to control multiple multimedia servers according to the instructions of the controller, thereby improving the stability and reliability of system control.

[0120] As an optional embodiment, it also includes: receiving audio data stored in the host computer through a network interface, and storing the audio data on a local external storage device; when the physical trigger program determines to play the audio data, the audio data is played through an audio playback device connected to the audio interface.

[0121] Since the number of ports on the controller may be limited, it may not be practical in some cases. Therefore, the controller can be expanded to provide more expansion ports for the controller chip by using a splitter and input / output interface, so as to connect more physical trigger devices.

[0122] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0123] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0124] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
