Description

Technical Field

[0001] This invention relates to the field of conference discussion system technology, and in particular to a conference discussion method, conference unit, storage medium and system. Background Technology

[0002] The current conference discussion system uses a host connected to the main cable, such as Figure 1 As shown, the main cable connects to a conference unit, and other conference units are connected to this unit one by one in a daisy-chain manner. The host, as the confluence node for all conference units, uses this cable to issue commands, manage and make decisions to each conference unit, and send and receive audio signals. Data is transmitted and received between the host and the conference units in half-duplex or full-duplex mode. For example, if a conference unit initiates a speak-enabled operation, and the host receives the signal, it sends a command back to the conference unit to allow or deny the conference unit from speaking. If multiple conference units initiate operations simultaneously, it will cause bus contention or congestion, increasing the failure rate or latency.

[0003] This method, which requires a separate host and uses cables to provide DC power and bidirectional data transmission to the conference units, also has drawbacks: the host and conference units are often far apart in the field, resulting in excessively long main cables, limited power supply capacity leading to limited load capacity, and the need to add additional power supply equipment for relaying; excessively long cables also increase the bit error rate during digital signal transmission; all of these factors contribute to an increased system failure rate.

[0004] Traditional conference systems have been using the same transmission methods for many years. They need to consider the compatibility of various interfaces, and the daisy chain connection also needs to consider the problem of each conference unit competing for the bus, which makes the design complex, the cost high, and the wiring complex in engineering. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a meeting discussion method, a meeting unit, a storage medium, and a system.

[0022] Furthermore, the meeting discussion method described in this invention also includes:

[0023] When the conference unit is connected to a power supply, it processes the power signal separated from the first data and the power signal provided by the power supply to avoid power supply conflicts.

[0028] When the conference unit is a slave device, it sends device status and / or data transmission and reception information to the conference unit that is the master device.

[0029] In addition, the present invention also provides a computer storage medium storing a computer program that, when executed by a processor, implements the steps of the meeting discussion method described above.

[0041] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the invention are now described in detail with reference to the accompanying drawings. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "linking," "fixing," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or a connection within two elements or an interaction between two elements. When an element is referred to as being "on" or "below" another element, the element can be located "directly" or "indirectly" on the other element, or there may be one or more intermediary elements. The terms "first," "second," and "third," etc., are used only for the convenience of describing the technical solution and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first," "second," "third," etc., may explicitly or implicitly include one or more of that feature. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0042] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0043] In a preferred embodiment, reference Figure 2 The meeting discussion method of this embodiment is applied to a meeting unit, and the method includes the following steps:

[0044] S10. Receive the first data sent by the previous conference unit. Multiple conference units are sequentially connected in a daisy-chain configuration to form a ring link. Optionally, conference units are sequentially connected in a daisy-chain configuration to form at least one ring link with the same or different data transmission directions. The first data includes the identifier of the target conference unit and a first instruction to be executed. S20. Based on the identifier of the target conference unit, determine whether the first data contains a first instruction that this conference unit needs to execute. S30. If yes, parse and execute the first instruction in the first data, and send the parsed first data to the next conference unit. S40. If not, send the first data to the next conference unit. It should be noted that the first data includes the sender's voice data, displayed files, videos, etc. That is, when a conference unit receives the first data, it can directly obtain this common data, and then further determine whether the first data contains a first instruction to be executed sent to it by another conference unit, based on the identifier of the target conference unit, such as a specific flag.

[0045] The working principle of this invention is as follows: data is transmitted unidirectionally in a ring link, ensuring continuous data transmission. Each conference unit checks the received signal for any instructions intended for it. If an instruction is found, it is extracted and processed; otherwise, it is forwarded to the next-level conference unit. If an instruction needs to be sent, it embeds the instruction to the target conference unit into the data before forwarding it to the next-level conference unit. The corresponding conference unit receives the instruction, processes it, and embeds the processing result into the forwarded data. This avoids bus conflicts and ensures relatively fixed data transmission and reception times.

[0046] Specifically, the output of one conference unit is connected to the input of the next conference unit, and the output of the last conference unit is connected to the input of the first conference unit. All conference units form a ring link, and a power supply is connected to at least one conference unit. Each conference unit receives data sent by the previous conference unit, extracts the instructions that the conference unit needs to execute from the data, and sends the data to the next conference unit. Data is circulated among all conference units and dynamically updated according to the actual needs of each conference unit. The power supply provides power to all conference units through the ring link. The first instruction includes, but is not limited to, power on / off instructions, peripheral device access instructions, and instructions for acquiring relevant data, etc.

[0047] Alternatively, the first data can be initiated by any conference unit. For example, if the data string is 10 bytes, the first byte corresponds to the first unit, the second byte corresponds to the second unit, and so on. Each unit can take only the data that is relevant to itself and the data in the common part. Specifically, it can be determined whether the data is for itself based on the flag bit.

[0048] In this embodiment, data can be transmitted sequentially and cyclically between conference units, avoiding multiple conference units competing for the bus. Each conference unit can receive data and issue instructions, so that the conference discussion system does not need to be configured with an additional host, thereby simplifying system deployment.

[0049] In some embodiments of the meeting discussion method, reference is made to Figure 3 It also includes the following steps:

[0050] S50. Receive the second instruction input by the user. S60. Embed the second instruction into the first data and send the first data containing the second instruction to the next conference unit. For example, if a user instructs conference unit 3 to turn on its microphone, this instruction includes who will execute it and the content to be executed. When the conference unit receiving this instruction receives the first data and before forwarding it to the next conference unit, it embeds its instruction to the target conference unit into the first data. The target conference unit, upon receiving the instruction, parses and executes it, then embeds the processing result into the first data and sends it back to the conference unit that issued the instruction. The conference unit that issued the instruction will receive the processing result when it receives the first data for the second time.

[0051] Preferably, receiving a second instruction input by the user includes, but is not limited to, receiving a second command input by the user via mechanical keys, and / or receiving a second instruction input by the user via touch keys, and / or receiving a second instruction input by the user via a microphone, etc.

[0052] In this embodiment, data can be transmitted sequentially and cyclically between conference units, avoiding multiple conference units competing for the bus. Each conference unit can receive data and issue instructions, so that the conference discussion system does not need to be configured with an additional host, thereby simplifying system deployment.

[0053] In some embodiments of the conference discussion method, the step of receiving first data sent by the previous conference unit includes:

[0054] Receive the first data modulated together with the power signal, and separate the first data from the power signal.

[0055] The steps of embedding the second instruction into the first data and sending the first data containing the second instruction to the next conference unit include:

[0056] The second instruction is embedded in the first data, and the first data containing the second instruction, modulated together with the power signal, is sent to the next conference unit.

[0057] Preferably, when the conference unit is connected to a power supply, the power signal separated from the first data and the power signal provided by the power supply are processed to avoid power supply conflicts.

[0058] When a conference unit is the master device, it receives device status and / or data transmission / reception information from other conference units acting as slave devices. When a conference unit is a slave device, it sends device status and / or data transmission / reception information to the conference unit acting as the master device. Alternatively, the master / slave device settings can be configured via preset button operation modes or voice input modes, or set at the factory default. Alternatively, the conference unit that initiates the first data transmission can be set as the master device; that is, when a conference unit initiates the first data transmission, its master device status is triggered, and the master device can also synchronize data transmission.

[0059] In this embodiment, data can be transmitted sequentially and cyclically between conference units, avoiding multiple conference units competing for the bus. Each conference unit can receive data and issue instructions, so that the conference discussion system does not need to be configured with an additional host, thereby simplifying system deployment.

[0060] In another preferred embodiment, the computer storage medium of this embodiment stores a computer program that, when executed by a processor, implements the steps of the meeting discussion method described above.

[0061] In this embodiment, data can be transmitted sequentially and cyclically between conference units, avoiding the situation where multiple conference units compete for the bus.

[0062] In another preferred embodiment, the conference unit of this embodiment includes a processor and a memory storing a computer program. When the processor executes the computer program, it implements the steps of the conference discussion method as described above.

[0063] For example, such as Figure 4 As shown, the conference unit in this embodiment includes a signal separation module, a signal processing module, and a signal modulation module. The output terminal of the signal separation module is connected to the input terminal of the signal processing module and the input terminal of the signal modulation module, respectively.

[0064] The signal separation module receives and separates the modulated power signal and the first data. The signal processing module processes the first data, extracts the first instruction that the conference unit needs to execute, and controls the conference unit to execute the first instruction. When a second instruction needs to be sent, the signal processing module also inserts the second instruction into the first data to form updated first data. The signal modulation module modulates the first data or the updated first data onto the power signal and sends it out. Alternatively, the signal processing module can also receive and process local instructions, such as button commands for the conference unit, power on / off commands, peripheral device access commands, audio / video acquisition commands, etc.

[0065] Preferably, refer to Figure 5 The conference unit also includes a power input processing module. The input of the power input processing module is connected to the output of the signal separation module, and the output of the power input processing module is connected to the input of the signal modulation module. The power input processing module processes power signals from the signal separation module and power signals directly supplied by the power supply to avoid power supply conflicts.

[0066] This embodiment can improve load capacity, effectively reduce product cost, improve product reliability, and facilitate the deployment of conference discussion systems.

[0067] In another preferred embodiment, reference Figure 6 The conference discussion system of this embodiment includes multiple conference units as described above, which are sequentially connected in a daisy-chain manner to form a ring link. Specifically, the output of a conference unit is connected to the input of the next conference unit, and the output of the last conference unit is connected to the input of the first conference unit. All conference units form a ring link, and a power supply is connected to at least one conference unit. Each conference unit receives first data sent by the previous conference unit, extracts the instructions that the conference unit needs to execute from the first data, and sends the parsed first data to the next conference unit. The first data is cyclically transmitted among all conference units and dynamically updated according to the actual needs of the conference units. The power supply provides power to all conference units through the ring link.

[0068] Alternatively, the conference unit has a communication interface for receiving external signals for interaction and management. The first data sent and received by the conference unit includes, but is not limited to, audio data, video data, execution commands, etc. The first and second commands include, but are not limited to, power-on / off commands, peripheral device access commands, and commands for acquiring relevant data, etc.

[0069] Specifically, dynamic updating based on the actual needs of the conference units means that when a conference unit needs another conference unit to execute a certain instruction, the instruction is inserted into the first data to form updated data, and the updated first data is sent to the next conference unit. In other words, each unit can insert data or instructions to be sent into this first data string, or it can receive data or instructions from other units into this first data string. Specifically, it receives a second instruction input by the user, embeds the second instruction into the first data, and sends the first data containing the second instruction to the next conference unit. For example, if a user instructs conference unit 3 to turn on its microphone, this instruction includes who will execute it and the content to be executed. When the conference unit receiving this instruction receives the first data but before forwarding it to the next level conference unit, it embeds its instruction to the target conference unit into the first data. When the target conference unit receives the instruction, it parses and executes it, then embeds the processing result into the first data and sends it back to the conference unit that issued the instruction. The conference unit that issued the instruction will then receive the processing result when it receives the first data a second time. This first data string can be initiated by any conference unit. For example, if this first data string has 10 bytes, the first byte corresponds to the first unit, the second byte corresponds to the second unit, and so on. Each unit can take only the data related to itself and the data in the common parts. It can determine whether the data is for itself based on the identifier of the target conference unit, such as the flag bit.

[0070] The working principle of this invention is as follows: Each conference unit can be connected by cables to form a loop. A power supply is connected to one of the conference units, and this loop provides normal operating power to all conference units. When the power supplied by connecting only one conference unit is insufficient to meet the power needs of all conference units, the power supply can be connected to multiple conference units to satisfy their power requirements. Each unit has at least one pair of input / output interfaces, and data can be transmitted either wired or wirelessly.

[0071] In the first scenario, when the first data is transmitted via wired connection, the input / output power signals and the first data can be modulated onto the same set of cables to reduce the number of cables. Alternatively, the power signals and the first data can be transmitted on separate lines. In this case, the first data is transmitted sequentially in a unidirectional loop. Because the conference units form a unidirectional and closed loop, the first data is transmitted cyclically level by level within this loop. This avoids situations where several units compete for the bus, and the first data transmission delay is also very small. For example, using 48kHz synchronization, theoretically, there would only be a 1-second delay if there were 48,000 units. For instance, the audio signal collected by the conference unit responsible for speaking is transmitted sequentially to other conference units, and the receiving conference units amplify the sound through their built-in speakers. If external amplification equipment is required, one unit can also output audio signals to other devices.

[0072] The second method involves wireless transmission of the first data. In this case, each conference unit can transmit data either sequentially and cyclically according to the ring link or selectively, meaning that the conference units can send the first data to a designated receiving conference unit.

[0073] Preferably, each conference unit receives first data modulated together with a power signal from the previous conference unit via a ring link, demodulates and extracts the instructions that the conference unit needs to execute from the data, modulates the data together with the power signal, and sends it to the next conference unit. It should be noted that demodulation involves separating the modulated data and the power signal. (See reference...) Figure 7 Taking three meeting units as an example, the working principle of the meeting discussion system is further described through the cooperation between specific modules in the meeting units.

[0074] The working principle of this embodiment is as follows: the input terminal of the signal separation module of conference unit 1 is connected to the output terminal of the signal modulation module of conference unit 3. The output terminal of the signal separation module of conference unit 1 is connected to the input terminal of the signal processing module and the input terminal of the power input processing module. The output terminal of the power input processing module is connected to the input terminal of the signal modulation module. The output terminal of the signal modulation module of conference unit 1 is connected to the input terminal of the signal separation module of conference unit 2. The output terminal of the signal modulation module of conference unit 2 is connected to the signal separation module of conference unit 3. The three conference units form a ring link.

[0075] The first data is sent from the signal modulation module of conference unit 3 to the signal separation module of conference unit 1. The signal separation module of conference unit 1 receives the first data from the signal modulation module of conference unit 3 and separates the modulated power signal from the first data. Next, the signal processing module of conference unit 1 processes the separated first data, determining whether there is a first instruction to be executed for that conference unit based on the identifier of the target conference unit. If so, it extracts the first instruction to be executed by the conference unit and controls the conference unit to execute the first instruction. When a second instruction needs to be sent, the signal processing module can also insert the first instruction into the data to form updated data. Finally, the signal modulation module modulates the data or updated data onto the power signal and sends it to the signal separation module of conference unit 2. Similarly, the signal modulation module of conference unit 2 modulates the data or updated data onto the power signal and sends it to the signal separation module of conference unit 3, and so on, continuously transmitting data in this loop. The power input processing module mainly processes the power signal from the signal separation module and the power signal directly connected by the power supply to avoid power supply conflicts. The power signal received by the signal modulation module is a power signal that has been processed by the power input processing module.

[0076] Alternatively, the signal processing module can also be used to receive and process local commands, such as button commands for the conference unit, power on / off commands, peripheral device access commands, audio / video acquisition commands, and so on.

[0077] This embodiment further shortens the total cable length and reduces the total power by coupling data and power signals for transmission, simplifying the deployment of the conference discussion system. At the same time, it effectively reduces the data transmission error rate and failure rate, improves the load capacity, effectively reduces product costs, and improves product reliability.

[0078] Preferably, the conference discussion system includes at least one ring link with the same or opposite transmission directions. For example, taking two ring links with opposite transmission directions as an example, each conference unit includes two pairs of input / output terminals. For the first pair of input / output terminals, all conference units form a first ring link, and for the second pair of input / output terminals, all conference units form a second ring link.

[0079] In unidirectional communication, the conference system activates one of the ring links. In bidirectional communication, the system activates both the first and second ring links. Power is supplied to all conference units via the first and / or second ring links. That is, the communication directions of the two ring links are opposite: one transmits downwards, and the other transmits upwards.

[0080] Preferably, each conference unit can receive data sent by the previous conference unit via wireless communication, extract the instructions that the conference unit needs to execute from the data, and send the data to the next conference unit. Wireless communication methods include, but are not limited to, 2G wireless communication, 3G wireless communication, 4G wireless communication, 5G wireless communication, Bluetooth, WIFI, infrared, etc.

[0081] Furthermore, the conference discussion system also includes peripheral devices, which connect to at least one conference unit. That is, when external devices are needed, they can be connected through corresponding ports of one of the node units, such as audio ports and control ports. Peripheral devices can be at least one of amplification devices, microphones, video devices, projection devices, and display devices. Signals from the peripheral devices are received and processed in the signal processing module, and control signals received by the peripheral devices are also obtained from the signal processing module.

[0082] Furthermore, one conference unit can be designated as the master unit, with the others as slave units. This allows for arbitrary configuration of any conference unit as the master, with the others as slave units, enabling conference management. Alternatively, to reduce costs, a version with both master and slave unit hardware configurations can be designed. The master unit can monitor the status of slave units in real time, or summarize and report the status of slave units. As an option, master and slave device settings can be configured via preset button operation modes or voice input modes, or factory settings. Alternatively, the conference unit that initiates the first data transmission can be designated as the master device; that is, when a conference unit initiates its first data transmission, it will be automatically designated as the master device, and the master device can also synchronize data transmission.

[0083] The conference discussion system in this embodiment avoids multiple conference units competing for the bus, shortens the total cable length, reduces total power, effectively reduces data transmission error rate and failure rate, improves load capacity, effectively reduces product cost, improves product reliability, and simplifies the deployment of the conference discussion system. In wired unidirectional transmission, it can also reduce the internal wiring of the cable, allowing for the use of as few as two core wires, resulting in thinner cables that are easier to use.

[0084] It is understood that the above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of the present invention, and can also make several modifications and improvements, all of which fall within the protection scope of the present invention. Therefore, all equivalent transformations and modifications made with respect to the scope of the claims of the present invention should fall within the scope of the claims of the present invention.
