Description

TECHNICAL FIELD

[0001] The present application relates to the field of offline voice communication, in particular to an offline voice phone and a control method. BACKGROUND

[0002] In modern hotels, telephones are widely distributed in every room as standard intelligent devices. However, with the popularity of smart phones and their increasing powerful functions, the use of hotel telephones has been gradually simplified, focusing on a single function of communicating with the front desk. At the same time, traditional telephones have been difficult to meet the requirements of modern hotels for space optimization and intelligentization of intelligent devices due to their large size, room space occupation, and cumbersome cleaning and maintenance. Therefore, there is an urgent need for an integrated and simplified product that can retain telephone functions and adapt to modern intelligent hotel systems.

[0003] At the same time, voice control technology, as an important branch of artificial intelligence, has been widely applied in various scenarios. Voice control not only brings a sense of technology to guests, but also enables touchless control of intelligent devices in the room, such as lights, air conditioners, curtains, and televisions, providing a more convenient and intelligent user experience for hotel rooms. However, most voice-controlled intelligent devices on the market exist in the form of independent speakers, which requires additional space and independent power supply, and is not harmonious with the overall decoration style of the hotel room in appearance.

[0004] In addition, with the development of intelligentization, a gateway intelligent device is commonly equipped in hotel rooms to realize "edge computing" of individual rooms and centralized control of intelligent devices. However, traditional gateway intelligent devices are usually large in size, require separate placement, and are equipped with independent power supply interfaces. This design is not only aesthetically pleasing, but also not conducive to stable transmission of wireless signals, and usually needs to be hidden in poor environments such as the ceiling or the bottom of a television cabinet. This not only affects the stable operation of intelligent devices, but also increases the difficulty of installation and maintenance. SUMMARY

[0005] To effectively solve the above problems, the present application provides an offline voice phone and a control method.

[0006] To achieve the above purpose, one technical solution of the present application is an offline voice phone, comprising: an offline voice module for receiving user voice instructions and parsing instructions according to an instruction library pre-stored in the offline voice module to generate control signals and send them to a gateway module, and entering a silent mode or resuming normal work according to control commands from the gateway module; a telephone communication module for receiving control signals sent by the gateway module through a Bluetooth module to support operations related to communication; Bluetooth module, receiving control instructions sent by the gateway module, communicating with the smart device, the phone communication module and the speaker switching module, executing corresponding operations and feeding back the state to the gateway module; Speaker switching module, receiving switching signals sent by the gateway module through the Bluetooth module, used for switching between voice function and call function; Gateway module, communicating with the offline voice module, receiving control signals, analyzing instruction types, sending control instructions to the Bluetooth module to forward to the smart device, the speaker switching module and the phone communication module or directly sending to the offline voice module.

[0007] In some preferred technical solutions, the phone communication module adopts telephone line power supply, built-in telephone line adaptation circuit and low-power chip, and is connected with the Bluetooth module through an optical coupler.

[0008] In some preferred technical solutions, a speed dial key is further included, which is connected with the phone communication module.

[0009] In some preferred technical solutions, an external interaction module is further included, which interacts with the gateway module and triggers corresponding functions.

[0010] In some preferred technical solutions, the gateway system is connected with a server and data is interacted.

[0011] In some preferred technical solutions, an emergency power module is further included, which is used for providing short-time backup power supply support for the offline voice telephone when main power supply is interrupted.

[0012] In some preferred technical solutions, a monitoring and early warning module is further included, which is connected with the gateway module, used for monitoring the running state of the gateway module, and triggering a reset or warning signal when an abnormality is detected.

[0013] The application further includes another technical solution, an offline voice telephone control method, including the following steps: receiving and analyzing voice instructions of a user; generating control signals according to a pre-stored instruction library; when the control signals are telephone communication instructions, preferentially executing telephone communication operations and suspending processing of other voice instructions; when the control signals are smart device control instructions, executing control operations on corresponding smart devices; and feeding back execution results after the operations are completed.

[0014] In some preferred technical solutions, physical instructions of a user are further included; control signals are generated for the physical instructions; when the physical instructions are telephone communication instructions, preferentially executing telephone communication operations and suspending processing of other voice instructions; and feeding back execution results after the operations are completed.

[0015] Some superior technical solutions also include periodic or real-time monitoring of the smart device's operating status, issuing alarms and / or triggering restarts to restore normal function when abnormal operation is detected; establishing data communication with the server through the network to achieve data exchange with the server; and retrieving update files from the server through the network to remotely upgrade the target smart device when the system detects an upgrade requirement.

[0016] The beneficial effects of this invention are: This invention integrates contactless intelligent control with traditional call functions through the organic combination of an offline voice module, a telephone communication module, a Bluetooth module, a speaker switching module, and a gateway module. Compared to traditional telephone solutions, this invention is more compact in structure, embedding the offline voice telephone into a smaller standard panel (such as an 86 standard panel), significantly reducing space occupation and cleaning and maintenance workload, and allowing for better coordination with interior decoration styles. Through a pre-built voice command library and offline recognition technology, even in environments without network or with unstable networks, this invention can still achieve local control of intelligent devices such as lights, air conditioners, curtains, and televisions, and supports call operations such as one-click calling the front desk, thus meeting users' needs for privacy protection and contactless interaction. Employing telephone line power supply and a low-power chip design, the telephone can maintain call functionality even when the main power supply is interrupted, improving system reliability and practicality. Leveraging edge computing and OTA upgrade mechanisms, the gateway module can ensure uninterrupted room control functions through local caching files during network anomalies, and can also quickly and efficiently perform batch remote upgrades of intelligent devices through file-level data interaction, meeting the needs of rapid deployment and maintenance. This invention comprehensively meets the requirements of space utilization, user experience, security, and system scalability from multiple perspectives, providing an efficient, reliable, and flexible offline voice phone solution for various application scenarios.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0019] The present application provides an intelligent telephone based on offline voice control and a control method thereof. For the convenience of understanding, the functional architecture of the present application is introduced first. Please refer to Figure 1 The functional architecture of the present application includes foreground call, intelligent voice control, analog telephone, gateway, Bluetooth communication and intelligent device control and other core functions. Users can control the system with voice instructions to achieve convenient operation without contact; the analog telephone is used for traditional telephone replacement and call function reservation, supports quick dialing and hands-free calling and the like; the gateway is used as the control center of the system, responsible for instruction analysis, device management and data interaction with the server; the Bluetooth communication connects various modules to realize efficient interaction between devices; the intelligent device control covers lighting, air conditioning, curtains and television and other devices.

[0020] The telephone mainly consists of offline voice module, telephone communication module, Bluetooth module, speaker switching module and gateway module and other core components. The specific implementation of the telephone system will be described in detail below, including hardware structure, working process and specific application scenarios.

[0021] Please refer to Figure 2 The offline voice telephone includes an offline voice module 1 for receiving user voice instructions and analyzing the instructions according to the instruction library pre-stored in the offline voice module 1, generating control signals and sending them to the gateway module 5, and entering the silent mode or resuming normal work according to the control commands of the gateway module 5; A telephone communication module 2 receives the control signals sent by the gateway module 5 through the Bluetooth module 3, and is used to support operations related to calls, such as supporting quick dialing, hands-free calling and ring control functions; A Bluetooth module 3 receives control instructions sent by the gateway module 5, communicates with the intelligent device 6, the telephone communication module 2 and the speaker switching module 4, executes corresponding operations and feeds back the status to the gateway module 5; A speaker switching module 4 receives switching signals sent by the gateway module 5 through the Bluetooth module 3, and is used to switch between voice functions and call functions to ensure sound external output; A gateway module 5 communicates with the offline voice module 1, analyzes the instruction type after receiving the control signal, sends the control instructions to the Bluetooth module 3 and forwards them to the intelligent device 6, the speaker switching module 4 and the telephone communication module 2, or directly sends them to the offline voice module 1.

[0022] With the gateway chip as the core, communication functions between each module are realized through the Bluetooth module 3. At the same time, the offline voice module 1 is responsible for converting sound into control data, thereby realizing voice control. In one application scenario, the telephone communication module 2 is responsible for realizing the calling function with the front desk, ensuring that the user can conveniently make a voice call.

[0023] The above offline voice telephone integrates a three-in-one design, breaks away from the inherent form of traditional telephones, and allows the offline telephone to be integrated into a conventional 86 standard wall panel. It no longer occupies the tight bedside table space and adopts an embedded fixing method to avoid damage from falling. Conventional voice equipment is usually in the form of a sound, which needs to occupy an independent space and a power socket, and is easy to be out of harmony with the overall style. This design can completely solve the above pain points, retain the core unit part of the telephone, cancel the caller ID display, the calling handle and the traditional dialing keyboard, realize the free calling and one-key calling of the front desk.

[0024] The offline voice module 1 adopts an independent offline voice chip, which has built-in commonly used interactive words and supports up to several hundred to thousands of word libraries. Through the independent microphone pickup, the handle and the dialing keyboard are cancelled, and the user can call the front desk through offline voice. The whole process is in a non-contact state, which meets the needs of some hotel guests for non-contact operation.

[0025] In some embodiments, the offline voice chip exchanges data with the gateway chip set through a serial communication interface. In the system, a series of "smart device 6 control" instruction words are pre-set, which can help the system accurately identify the user's voice instructions, such as "turn on the air conditioner" and "turn off the curtain". When the user issues an instruction, the system will compare these pre-set words through voice recognition technology. Once the identification is successful, the system will send the corresponding address code to the gateway chip through the serial port protocol, thereby realizing the control of the corresponding smart device 6.

[0026] In this process, the user's voice information will not be transmitted to other places, and the system will not collect any unpre-set word information. In addition, the system will not collect the user's voiceprint information, will not distinguish the user's identity information, and will not upload any sound data to the server. All control instructions are converted into digital codes to ensure that the transmission and execution of instructions are more secure and reliable. This design maximizes the protection of customers' privacy from being leaked, and is particularly suitable for places with high privacy protection requirements, such as hotel rooms.

[0027] The gateway is the core component of the room intelligent device 6 control, and is designed and developed according to the idea of edge computing. The related room type, scene control and other conventional function files are all cached locally, so that the use experience of the room can be guaranteed to the maximum extent even in the case of network exception. Through the Bluetooth MESH communication mode, the gateway can manage all controlled intelligent devices 6 in the room.

[0028] Preferably, the telephone communication module 2 is powered by a telephone line, and is provided with a telephone line adaptation circuit and a low-power chip, and is connected with the Bluetooth module through an optical coupler. In addition, a speed dial key is also configured to be connected with the telephone communication module 2. The module adopts a telephone line power supply mode, and is provided with a rectification, filtering and voltage stabilization circuit to ensure the stable supply of the communication power supply. It can automatically perform reverse polarity conversion to adapt to different line conditions. The core control part of the telephone communication module 2 adopts a low-power chip set to reduce the overall energy consumption. In the case of off-hook and ringing, the telephone communication module 2 outputs signals through an optical coupler to ensure accurate signal transmission. The call front desk function button also uses an optical coupler for access, effectively solving the problem of voltage difference to ground existing in the switch. Only a "hands-free" call circuit and a single button are configured, which maximizes the reduction of circuit configuration and compresses the space occupation, making the device more compact. The front desk number is set in advance, and the user can quickly call the front desk through the "one-key" mode by starting the speed dial key. This not only improves the accuracy of dialing, but also greatly improves the dialing speed. The speaker and the offline voice share a relay for switching. In the normally closed state, the telephone is in an occupied state, so that users can still make normal calls even in the case of power failure, ensuring the continuity and reliability of communication.

[0029] The external interaction module interacts with the gateway module 5 and triggers corresponding functions. The external interaction module usually includes mute lights, mute keys, static keys and dynamic keys, etc. In the external interaction module, several function keys are generally used without occupying too much space. The dynamic key is used to display the device state or interactive prompt in real time in the system operation, and the current state of the device is fed back to the user through the change of the dynamic indicator light, such as device switching, running mode, etc. The dynamic key can be flexibly configured according to different scene requirements, which is convenient for users to intuitively understand the system operation and device state.

[0030] In practical applications, the gateway system connects with the server and exchanges data. When the system needs to be upgraded, the Bluetooth module 3 provides a reliable data channel for the OTA (Over-The-Air) upgrade of each smart device 6 module, ensuring that the smart device 6 can be updated to the latest firmware version in a timely manner, improving performance and security. During the OTA process of the room smart device 6, the gateway and the server exchange file-level data, which is fast and has a low error rate. The upgrade process is controlled independently by the gateway, allowing multiple rooms to perform OTA upgrades concurrently. The gateway function manages all controlled smart devices 6 in the room through Bluetooth MESH communication, ensuring coordination and efficient operation between different devices. Through wired network connection with the server, the system can upload the status of the smart devices 6 in the room in real time and implement real-time response to instructions, serving as a room control center. Of course, in addition to data interaction with the server through wired network connection, the system can be extended through other connection methods. For example, devices can be connected to the cloud or local server through Wi-Fi connection or other low-power wireless communication protocols, ensuring stable operation of the devices and system in different network environments. At the same time, the system also supports integration with external smart home platforms, allowing users to remotely operate and manage devices through mobile phone APPs, voice assistants (such as Xiaoai and Xiaodu), and other external control terminals.

[0031] In some embodiments, the phone also includes an emergency power module for providing short-term backup power support for the offline voice phone when the main power supply is interrupted. To accommodate the compact design of the offline voice phone, the emergency power module can use small lithium batteries or nickel-hydrogen batteries. In addition, a clock module can also be provided, which is connected to the gateway module 5 and the emergency power module. When the main power supply is whole, the clock module is powered by the gateway module 5, and when the main power supply is interrupted, the emergency power module powers the clock module and powers the offline voice phone through the clock module.

[0032] In practical applications, the phone includes a monitoring and warning module connected to the gateway module 5 for monitoring the running state of the gateway module 5 and triggering a reset or warning signal when an anomaly is detected.

[0033] In a specific embodiment, the monitoring and warning module is a "watchdog" that is mainly used to monitor the running state of the gateway module 5 in real time and ensure that the system can respond in a timely manner when an anomaly occurs. Specifically, the monitoring and warning module sends a status monitoring signal to the gateway module 5 at regular intervals through the connection with the gateway module 5, which is used to check whether the gateway is working normally. If no response from the gateway module 5 is received within the predetermined time, the monitoring module will trigger a reset operation to restart the gateway module 5 or issue a warning signal to prevent the system from being disabled for a long time or malfunctioning.

[0034] If the system fails to recover for a long time, the monitoring and warning module can also trigger an alarm signal, for example, send a notification to the server to prompt the administrator that the system has failed. At this time, the administrator can manually reset through the external interface or further troubleshoot the problem through remote means to ensure that the system can recover as soon as possible.

[0035] In this embodiment, the monitoring and warning module can effectively ensure the stable operation of the gateway module 5 and other devices, and ensure that the system can recover in time when the network or device fails. Through the watchdog mechanism and reset operation, the system will not be down for a long time when encountering an exception, thereby improving the reliability and user experience of the entire system.

[0036] In a specific application scenario, as shown in Figure 3 At the hardware level, the gateway module is connected with the Bluetooth module and the offline voice module through a serial port, responsible for receiving instructions and controlling devices. Other modules are connected with the gateway module through GPIO interfaces for state feedback and transmission of control instructions. These GPIO interfaces provide a flexible inter-module communication method to ensure that each device module can work cooperatively. When the gateway module cannot respond normally, the monitoring and warning module communicates with the gateway through the REST interface to trigger a reset signal, so that the system can self-repair and restore normal operation. When the gateway module does not reply to the state query request sent by the monitoring and warning module within a predetermined time, the monitoring and warning module will send a reset instruction to the gateway through the REST interface, so that the gateway module restarts and reinitializes the connection and control logic of each module; if the problem is still not solved after several restarts, the monitoring and warning module can trigger an alarm signal to report to the server, so that the operation and maintenance personnel can remotely diagnose and handle the fault condition. This self-diagnosis and self-recovery mechanism ensures that the system can quickly recover to normal operation when an exception occurs, avoiding long-term impact on users due to faults.

[0037] In addition, the bottom interface of the gateway module is designed with multiple connection ports, including an LN terminal post, an RJ45 network interface, and a 2P phone interface. The LN terminal post is used to connect the mains power supply to provide main power input for the gateway module and related components; the RJ45 network interface is used to connect the wired Ethernet to ensure high-speed and stable data communication between the gateway module and the server, realizing real-time response of device state uploading and remote control instructions; the 2P phone interface is used to connect the phone communication module with the traditional telephone line to realize access to the telephone line and reservation of the call function, so that basic call operations can still be performed through the telephone line power supply when the mains power is interrupted.

[0038] In one implementation, as shown in Figure 4 The offline voice phone control method includes the following steps, S101, receiving and analyzing the user's voice instruction; S102, generating a control signal according to a pre-stored instruction library; S103, when the control signal is a telephone communication instruction, preferentially executing a telephone communication operation and suspending processing of other voice instructions; S104, when the control signal is a smart device control instruction, executing a control operation on a corresponding smart device; S105, feeding back an execution result.

[0039] The following is further illustrated by using a scene example. The pre-stored instruction library is a location code existing on an offline voice module. The voice instruction is an instruction text: Use scenario 1: voice call front desk In this use scenario, first, the user activates the offline voice module through a wake-up word, and then speaks the instruction "dial the front desk". After receiving the instruction, the offline voice module compares the voice keyword location code corresponding to the instruction "dial the front desk" in its internal database, for example, "0x0123". Once the recognition is successful, the offline voice module sends the location code to the gateway main chip through the serial port. After receiving the location code, the gateway main chip sends a control instruction to the Bluetooth module through the serial port, instructing it to dial the front desk. After receiving the instruction, the Bluetooth module switches the loudspeaker to the telephone end through the relay, and notifies the analog telephone to turn on and dial the front desk through the optocoupler circuit, thereby realizing the function of calling the front desk.

[0040] Use scenario 2: voice open curtains In this use scenario, the user first activates the offline voice module through a wake-up word, and then speaks the instruction "open the curtains". After receiving the instruction, the offline voice module compares the voice keyword location code corresponding to the instruction "open the curtains" in its internal database, for example, "0x0567". Once the recognition is successful, the offline voice module sends the location code to the gateway main chip through the serial port. After receiving the location code, the gateway main chip sends a control instruction to the Bluetooth module through the serial port. After receiving the instruction, the Bluetooth module sends the instruction to the curtain control module through the wireless signal of Bluetooth MESH. After receiving the instruction, the curtain control module executes the action of opening the curtains and reports the execution result to the gateway chip. After receiving the reply from the curtain control module, the gateway chip broadcasts the execution result "the curtains have been opened" through the offline voice module to confirm that the instruction has been successfully executed. At the same time, the gateway chip also reports the state of the opened curtains to the background system through the TCP network to ensure the transparency and traceability of the entire operation process.

[0041] In one implementation, as shown in Figure 5 the offline voice telephone control method comprises the following steps, S201, receiving and analyzing a user's voice instruction or accepting a physical instruction; S202, generating a control signal according to the pre-stored instruction library or generating a control signal for a physical instruction; S203, when the control signal is a telephone communication instruction, preferentially executing a telephone communication operation and suspending processing of other voice instructions; S204, feeding back an execution result.

[0042] In one specific application scenario, a user issues a smart device control instruction (such as a voice instruction "open the curtain") through voice and presses a physical button (such as a speed dial key) at the same time or almost at the same time to initiate a foreground call request. According to the control logic of the present application: The system first receives the voice instruction "open the curtain" of the user and performs analysis (corresponding to steps S201 and S202), and generates a control signal of the smart device control type to be sent to the curtain control module.

[0043] At almost the same time, the user presses the physical button, which belongs to physical instruction input. After the system analyzes the physical instruction, it finds that it is a telephone communication instruction (such as calling the front desk), and needs to preferentially execute a telephone communication operation (corresponding to step S203).

[0044] Because the telephone communication instruction has a higher priority, the system will suspend the processing of the previous voice instruction ("open the curtain") and immediately execute the operation of dialing the front desk. At this time, the Bluetooth module will send a dialing signal to the telephone communication module, and the speaker switching module will switch to the call mode to ensure smooth call.

[0045] After the call operation is completed, the system resumes processing of the previous voice instruction that has not been completed, continues to send the control signal "open the curtain" to the curtain control module, and feeds back the execution result through the offline voice module after the curtain is opened.

[0046] Through this scenario, it can be seen that when a voice instruction (smart device control) and a physical instruction (telephone communication) appear at the same time, the system preferentially executes the telephone communication instruction according to the predetermined priority strategy, and suspends the processing of other instructions, thereby effectively avoiding instruction conflict and resource contention, ensuring the timely execution of the priority instruction (call operation) and the continuity of user experience.

[0047] The offline voice telephone control method further comprises periodically or in real time monitoring the running state of the smart device, issuing an alarm and / or triggering a restart to restore normal function when a running exception is detected; establishing data communication with a server through a network to realize data exchange between the server; when the system detects an upgrade requirement, obtaining an update file from the server through the network to remotely upgrade the target smart device.

Secondly, those skilled in the art should know that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily necessary for the present application.
