Description

Technical Field

[0001] This invention relates to the field of factory workshop repair reporting systems, specifically to a wearable real-time reminder method and system for repair information based on sound-to-electricity conversion. Background Technology

[0002] The existing repair system's alert function mainly relies on the computer interface and connected audio equipment for sound prompts. This mechanism has significant limitations: the alert only applies to a single work node. If the person receiving the order temporarily leaves their workstation or is far from the computer, they may not perceive the voice alert, leading to delays in order processing. Such situations can easily cause untimely work order responses, affecting overall processing efficiency and potentially wasting time and human resources.

[0003] An existing IoT management method and system receives information that needs to be processed or known by operators from IoT-connected devices via an IoT control server, and then sends the information to wearable electronic devices to remind operators of information that needs to be processed or known, thus preventing information from being ignored and not being processed in a timely manner, and freeing operators from having to constantly monitor the interactive computer. However, this solution requires the additional setup of an IoT server for application in the IoT field, making it difficult to directly apply to the reminders in a repair system. Summary of the Invention

[0004] The primary objective of this invention is to provide a wearable real-time reminder method for repair information based on sound-to-electric conversion, which can solve the problems of order delays caused by the absence of the personnel receiving the order at the repaired equipment, as well as the complexity of the implementation method.

[0005] The second objective of this invention is to provide a system for implementing the above-mentioned wearable real-time reminder method for repair information based on sound-to-electric conversion.

[0006] To achieve the aforementioned first objective, the present invention provides a wearable real-time reminder method for repair information based on sound-to-electric conversion, comprising the following steps: acquiring a switch electrical signal converted from a preset audio signal; wherein the preset audio signal corresponds to a specific prompt tone emitted by an external repair system; acquiring work order information output by the repair system; and sending a prompt message to the external wearable system based on the work order information.

[0007] As can be seen from the above solution, this invention monitors specific sound events to obtain a preset audio signal, which is then converted into a switching electrical signal. Upon obtaining the switching electrical signal, it acquires work order information and sends a notification to an external wearable system to alert the order taker. This invention enables remote notification of order takers who are not near the repair equipment, eliminating concerns about losing access to order information while away from their computers. Furthermore, because it does not require modification of existing repair equipment, the solution is simpler to implement and has a wider range of applications.

[0008] A further solution is to obtain the work order information output by the repair system through the UART interface.

[0009] Therefore, it can be seen that work order information in data form can be obtained by utilizing the UART output function of the repair system.

[0010] A further solution is to send a notification message to the wearable system based on the work order information, including processing the work order information and encoding it in JSON format to obtain the notification message.

[0011] This demonstrates that the size of data packets can be reduced, enabling efficient transmission to external wearable systems.

[0012] A further proposed solution is to include the work order information in the form of a repair order number, equipment location, and fault code.

[0013] Therefore, it can be seen that the work order information is order information in the form of data, which is recorded in the core content of the order information so that the personnel receiving the order can quickly confirm the problem.

[0014] A further solution is to provide prompts in text or voice format.

[0015] This shows that notifications can be delivered in a variety of ways.

[0016] A further proposal is to have a specific prompt tone with a frequency range of 800Hz to 2kHz.

[0017] Therefore, it is clear that there is no need to consider the specific content of the voice, but to determine the existence of order information directly through the frequency characteristics of the voice itself.

[0018] To achieve the second objective mentioned above, this invention provides a wearable real-time reminder system for repair information based on sound-to-electric conversion, comprising: a repair device, a reminder device, and a wearable device; the repair device and the reminder device are connected via wired communication, and the reminder device and the wearable device are connected via wireless communication; the reminder device includes a sound-to-electric conversion module, a control module, and a wireless transmission module, with the control module connected to both the sound-to-electric conversion module and the wireless transmission module; the repair device emits a specific prompt tone upon receiving an order message and outputs corresponding work order information to the reminder device; the reminder device implements the aforementioned wearable real-time reminder method for repair information based on sound-to-electric conversion, wherein the sound-to-electric conversion module collects a preset audio signal and converts it into a switching electrical signal, wherein the preset audio signal corresponds to a specific prompt tone emitted by the repair system; the control module, upon receiving the switching electrical signal output by the sound-to-electric conversion module, acquires the work order information output by the repair system and outputs a prompt message to the wireless transmission module based on the work order information; the wireless transmission module sends the prompt message to the wearable device; and the wearable device receives the prompt message and issues a corresponding reminder.

[0019] As can be seen from the above solution, the prompting module of the present invention directly utilizes the specific prompting sound when the existing repair equipment receives the order information, thereby obtaining the work order information from the repair equipment and sending it wirelessly to the wearable device. The wearable device is worn by the order taker who is not at the repair equipment, thereby realizing the function of remotely notifying the order taker. Since there is no need to modify the existing repair equipment or add an extra server, the implementation of the present invention is simple and convenient for application and promotion.

[0020] A further solution is to use a smartwatch as the wearable device; the wireless transmission module sends notification messages based on the Bluetooth Low Energy protocol.

[0021] A further approach is to adopt a tiered alert strategy when wearable devices receive notifications and issue corresponding reminders.

[0022] This demonstrates that wearable devices can alert order takers through real-time vibrations and visual information at different levels.

[0023] A further solution is that the reminder device includes a voice synthesis module, a LoRa wireless communication module, and a walkie-talkie as the wearable device; the voice synthesis module is used to convert the reminder information into voice form; and the LoRa wireless module is used to send the voice reminder information to the walkie-talkie.

[0024] Therefore, it is also possible to notify the order taker via voice. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0029] The wearable real-time reminder method for repair information based on sound-to-electric conversion of the present invention monitors the specific prompts emitted by the repair system in real time. When the specific prompt is detected, a prompt message is generated based on the acquired work order information and sent to the external wearable system, thereby informing the remote order taker.

[0030] First embodiment of a wearable real-time reminder system for repair information based on sound-to-electricity conversion: See Figure 1 This embodiment includes a repair reporting device 10, a reminder device 20, and a wearable device 30. The repair reporting device 10 is connected to the reminder device 20, and the reminder device 20 is connected to the wearable device 30, thereby enabling data transmission between the repair reporting device 10 and the reminder device 20, as well as between the reminder device 20 and the wearable device 30.

[0031] In this embodiment, the repair reporting device 10 and the reminder device 20 are connected via wired communication, and the reminder device 20 and the wearable device 30 are connected via wireless communication.

[0032] The repair device 10 is used to emit a specific prompt tone through its built-in speaker device after receiving an order message, and output the corresponding work order information to the reminder device 20.

[0033] The repair reporting device 10 is an existing repair reporting device with a repair reporting system running on it. This system receives order information, which is a message that the order taker needs to pay attention to. In the prior art, the repair reporting device is often a computer device, including a display screen and a speaker. The display screen shows the currently received order information, and the speaker plays a voice notification, allowing the order taker at the computer device to process it promptly. However, when the order taker is not at the computer device, they cannot know whether they have received the order information. Therefore, this embodiment uses a reminder device 20 and a wearable device 30 to work together to remind the order taker to pay attention.

[0034] The work order information in this embodiment includes a repair order number, equipment location, and fault code. The frequency range of the specific prompt tone is 800Hz to 2kHz. In different embodiments, the specific content of the work order information and the frequency range of the specific prompt tone can be adjusted according to actual conditions.

[0035] The repair device 10 in this embodiment has a serial port output function (such as RS232, USB to TTL UART), which can output the text data corresponding to the order information, that is, output the work order information.

[0036] See Figure 2 The reminder device 20 includes an audio-to-electric conversion module 201, a control module 202, and a wireless transmission module 203. The control module 202 is connected to the audio-to-electric conversion module 201 and the wireless transmission module 203.

[0037] In the reminder device 20, the sound-to-electricity conversion module 201 is used to collect a preset audio signal and convert it into a switching electrical signal, wherein the preset audio signal corresponds to a specific prompt tone issued by the repair system. The control module 202, after receiving the switching electrical signal output by the sound-to-electricity conversion module 201, obtains the work order information output by the repair system of the repair device 10, and outputs a prompt message to the wireless transmission module 203 based on the work order information. The wireless transmission module 203 is used to send the prompt message to the wearable device 30.

[0038] The reminder device 20 is wired to the repair device 10 via UART, allowing it to obtain work order information from the repair device 10. The sound-to-electricity conversion module 201 is positioned close to the speaker of the repair device 10, ensuring it can clearly receive the sound emitted by the repair system's speaker. This enables real-time monitoring of the specific prompt tone emitted by the repair device 10 when it receives order information. When the sound-to-electricity conversion module 201 detects the presence of a specific prompt tone, it determines that a preset audio signal has been acquired and outputs a switch signal to the control module 202. Optionally, if the duration of the specific prompt tone exceeds a set duration, the sound-to-electricity conversion module 201 confirms that the preset audio signal has been acquired to prevent false triggering.

[0039] The sound-to-electricity conversion module 201 can be used for monitoring based on existing audio recognition chips, such as the WT588D. The sound-to-electricity conversion module 201 can output switching electrical signals via existing optocouplers, such as the PC817. This allows for a response delay of less than 50ms and a false trigger rate of less than 0.1% for monitoring specific prompt tones.

[0040] The control module 202, based on a microcontroller (such as STM32F103), receives a switch signal and determines that there is an order for the device 10 currently requiring repair. It then retrieves the corresponding work order information from the device 10 via a UART interface. The module extracts the repair order number, device location, and fault code from the work order information and processes it into a JSON-formatted prompt message (example: {"order":"REQ2025-08","loc":"A3_line","code":"E102"}). This allows the repair information to be compressed into a standardized data packet of <100 bytes. The wearable device 30 has pre-defined field encoding rules, which can be used to parse the content of this standardized data packet and provide prompts. For example, the fault code "E102" is mapped to motor overload.

[0041] In different embodiments, the prompt information can be in text or voice form; this embodiment uses text.

[0042] The wireless transmission module 203 can be implemented using a Bluetooth module, which is based on the Bluetooth Low Energy (BLE 5.0) protocol, to send the prompt information to the wearable device 30. This embodiment is applied in scenarios where the person receiving the order is relatively close to the equipment 10 being repaired (≤50m), meeting the needs of general factory environments. It is understood that different communication modules can be used in different embodiments to achieve signal transmission over different distances.

[0043] In different embodiments, the prompt message may also be encrypted before being sent to the wearable device 30 to improve security, for example, by using AES-128 encryption.

[0044] Wearable device 30 is used to receive prompts and issue corresponding reminders, and it runs a wearable system that implements the reminder function. Wearable device 30 is worn by the person receiving the order. When wearing device 30 receives prompts and issues corresponding reminders, it adopts a tiered reminder strategy. For example, the initial reminder is a watch vibration and a constantly lit screen for 10 seconds. If there is no response after a preset time (e.g., more than 2 minutes), the vibration is amplified and an alarm is issued via sound, and the message is automatically forwarded to the superior administrator's terminal, such as to the wearable device of the superior manager.

[0045] In this embodiment, the wearable device is a smartwatch. In other embodiments, it could be any other device carried by the person receiving the order. The smartwatch in this embodiment can be an existing smartwatch or a smartwatch with customized firmware. The customized firmware needs to implement functions such as a priority vibration mode (continuous vibration for 3 seconds + interval repetition), displaying repair details (device location + fault code) on an OLED screen, and a one-click mute button (physical button / touchscreen).

[0046] In different embodiments, there can be multiple wearable devices, such as simultaneously pushing notification information to the smartwatch, smartphone, AR glasses, etc. of the person receiving the order.

[0047] Second embodiment of a wearable real-time reminder system for repair information based on sound-to-electricity conversion: The difference between this embodiment and the first embodiment described above is that the prompt information is in voice form without encoding. The reminder device includes a speech synthesis module, a LoRa wireless communication module, and a walkie-talkie as the wearable device. Specifically, when the control module outputs prompt information based on the work order information, the prompt information is not encoded but processed into natural language. This is then converted by the speech synthesis module and transmitted to the walkie-talkie via the LoRa wireless module. The walkie-talkie then emits an audio alert to the person receiving the order.

[0048] Example of a wearable real-time reminder method for repair information based on sound-to-electricity conversion: This embodiment is based on the first embodiment of the wearable real-time reminder system for repair information based on sound-to-electricity conversion described above. Specifically, the control module of the reminder device implements this embodiment by executing a computer program, see [link to relevant documentation]. Figure 3 The following will explain each step in detail.

[0049] First, step S1 is executed to obtain the switching electrical signal converted from the preset audio signal. After the equipment receiving the order information, it emits a specific prompt tone, allowing the audio-to-electrical conversion module to obtain the preset audio signal and then output the switching electrical signal to the control module.

[0050] Then, step S2 is executed to obtain the work order information output by the repair system. Specifically, since the repair device in this embodiment is connected to the reminder device via a USB-to-TTL UART converter, when obtaining the work order information output by the repair system, the control module obtains the work order information output by the repair system running on the repair device through the UART interface of the reminder device.

[0051] Finally, step S3 is executed, sending a notification message to the external wearable system based on the work order information. Specifically, the work order information is processed into a JSON-encoded notification message and sent to the wearable device. The wearable system running on the device then notifies the person receiving the order of any order information requiring attention regarding the reported equipment.

[0052] In summary, the notification module of this invention directly utilizes the specific notification sound of existing repair equipment when it receives order information, thereby obtaining work order information from the repair equipment and sending it wirelessly to a wearable device. The wearable device is worn by the person receiving the order who is not at the repair equipment, thus realizing the function of remotely notifying the person receiving the order. Furthermore, since there is no need to change the existing repair equipment, the implementation of the solution is simpler and the application scope is wider.

[0053] Finally, it should be emphasized that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
