[0046] As Figure 2 The structure schematic diagram of the second embodiment of the maintenance auxiliary prompting system is shown.

The auxiliary decision circuit analyzes these input parameters to understand the current state and running trend of the equipment. The auxiliary decision circuit evaluates the equipment, through the evaluation, the auxiliary decision circuit can determine which equipment needs more frequent maintenance and more meticulous maintenance. Based on the state evaluation and risk analysis of the equipment, the auxiliary decision circuit formulates appropriate maintenance strategies for the user. These strategies include preventive test maintenance plan, regular maintenance plan and emergency maintenance plan for specific faults. This may include recommended maintenance time, maintenance content, required materials and maintenance personnel, etc. The auxiliary decision circuit generates early warning and alarm information according to the collected equipment state data through the preset algorithm and threshold, which is crucial for timely discovery and processing of potential faults.

[0050] The system comprises a maintenance reporting circuit 500; the maintenance reporting circuit is connected with the prompt circuit and the auxiliary decision circuit; the maintenance reporting circuit is used for receiving the fault signal output by the auxiliary decision circuit, analyzing the fault reason according to the comparison result of the input parameter and the preset parameter, and outputting a fault diagnosis result to the prompt circuit.

[0051] It can be understood that the maintenance declaration circuit analyzes and counts the collected input parameters to generate various reports and charts, such as equipment failure rate statistics, maintenance cost analysis, etc. According to the comparison result of the input parameters, the fault reason is analyzed, and when declaring maintenance, the name, model, position, etc. Basic information of the equipment to be maintained is sent to the prompt circuit, and the specific content of the maintenance is described in detail, such as replacement of equipment parts, fault repair, preventive test, etc.

[0052] The system comprises a fault maintenance circuit 600; the fault maintenance circuit is connected with the maintenance declaration circuit and the prompt circuit; the fault maintenance circuit is used for extracting the maintenance process data corresponding to the equipment according to the fault diagnosis result, and sending the maintenance process data to the prompt circuit.

[0053] It should be noted that the fault phenomenon is observed and recorded, such as indicator light flickering, alarm sound, etc. The maintenance personnel are prompted to try to reproduce the fault by operating the equipment, so as to more accurately understand the fault characteristics. According to the fault phenomenon, the possible fault reason is preliminarily judged, the operation log, maintenance record, etc. of the equipment are checked to understand the historical condition of the equipment. The user is prompted to use the multimeter, oscilloscope, etc. Tool to test the electrical performance of the equipment, such as voltage, current, resistance, etc. Check the electrical connection and output of the power module, sensor, actuator, etc. According to the fault positioning result, take corresponding repair measures, such as replacing damaged parts, such as sensors, circuit boards, etc. Adjust the equipment configuration or update the software to solve the software related fault.

[0054] It can be understood that the fault maintenance circuit stores the fault history record of the equipment, including the time, type, reason and maintenance measures taken when the fault occurs. It is used to analyze the fault mode and trend of the equipment, so as to optimize the next maintenance strategy.

[0056] As shown in Figure 2 The structure diagram of the third embodiment of the maintenance auxiliary prompt system proposed in this embodiment.

[0057] Based on the above-mentioned first embodiment and / or second embodiment, the third embodiment of the maintenance auxiliary prompt system of the utility model is proposed.

[0058] The prompt circuit is configured to display the operation content, required tools and matters needing attention of each step in the form of pictures and texts to the maintenance personnel.

[0059] The prompt circuit is configured to switch to the next step prompt when receiving the confirmation signal input by the maintenance personnel after completing the current step.

[0060] It can be understood that through the high-definition display screen or projection device, the prompt circuit can clearly present the specific operation steps of each maintenance step. These steps are usually listed in a step-by-step manner, and each step is equipped with concise and clear text instructions. While displaying the operation content of each step, the prompt circuit also explicitly lists the various tools required to complete the step, such as screwdrivers, pliers, testers, etc. This helps the maintenance personnel to prepare the required tools in advance, thereby improving work efficiency. For each operation step, the prompt circuit will specially mark potential safety hazards and matters needing attention, such as "Please make sure that the power supply has been completely disconnected before disassembly", "Avoid using damaged tools", etc. These prompts help the maintenance personnel to avoid operation risks and ensure the safe operation of the maintenance process.

[0061] Optionally, the prompt circuit also has an interactive function, allowing the maintenance personnel to operate the prompt circuit through the touch screen or other input devices. The prompt circuit can also record key data during the maintenance process, such as the completion time of each operation step, the consumption of required tools, etc. These data can be used for subsequent maintenance cost analysis and equipment performance evaluation. In addition, the prompt circuit can also collect feedback from the maintenance personnel in order to continuously optimize and improve the maintenance process.

[0062] It should be noted that through intuitive pictures and text instructions, the maintenance personnel can quickly understand the maintenance steps and required tools, thereby shortening the maintenance time; clear instructions and potential safety hazards help the maintenance personnel to avoid operation risks and ensure the safe operation of the maintenance process; through data recording and feedback mechanism, the prompt circuit can continuously optimize the maintenance process and improve the reliability and stability of the equipment.

[0063] The prompt circuit further comprises a voice circuit 700 connected to the data extraction circuit, and the voice circuit is configured to voice broadcast the maintenance process data.

[0064] It can be understood that the voice circuit 700 is connected with the data extraction circuit, and can read and analyze the maintenance process data, and then convey the information to the maintenance personnel through voice broadcast. The voice circuit 700 first obtains the maintenance process data through the data extraction circuit. These data can include maintenance steps, required tools, precautions, and any text information related to the maintenance operation. Then, the voice circuit analyzes these data and converts them into a form suitable for voice broadcast. The voice broadcast function allows the maintenance personnel to focus more on the work at hand without having to look away to check the screen or paper documents, thereby improving maintenance speed and accuracy. In some high-risk or limited-visibility maintenance environments, voice prompts can help maintenance personnel better understand the current operation steps and potential risks, thereby reducing the probability of accidents.

[0065] Optionally, the voice circuit 700 can also have an interactive function, allowing the maintenance personnel to control the prompting device through voice instructions. For example, they can ask for a repeat broadcast of a certain step or jump to a specific maintenance stage. In addition, the voice circuit can also receive voice feedback from the maintenance personnel.

[0066] The data extraction circuit and the prompting circuit transmit data through wireless communication, and the wireless communication includes at least one of Bluetooth, Wi-Fi, and mobile network technology.

[0067] It can be understood that Bluetooth can realize point-to-point or point-to-multipoint wireless data and voice transmission at a short distance, and the data transmission bandwidth can reach 1 Mbps. In the data extraction circuit and the prompting circuit, Bluetooth technology can be used for short-distance, low-power data transmission. Wi-Fi has a wide local area network coverage range and very fast transmission speed, and in the data extraction and prompting circuit, Wi-Fi can be used for short-to-medium distance high-speed data transmission. Mobile network technologies such as GPRS and CDMA are important means of long-distance wireless communication, which can realize long-distance data transmission through cellular networks, and have the characteristics of wide coverage and stable transmission. When long-distance data transmission is required between the data extraction circuit and the prompting circuit, mobile network technology can be used to achieve this.

[0068] In the embodiment, before the maintenance personnel starts the maintenance work, the equipment to be maintained is selected through the trigger circuit, the maintenance process data corresponding to the maintenance of the equipment is extracted through the data extraction circuit, and the corresponding maintenance process data is sent to the prompt circuit in the order of steps.

[0069] It should be noted that in this paper, the term "including", "containing" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or system including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or includes elements inherent to such process, method, article or system. Without more limitations, the element defined by the statement "including a" does not exclude the existence of other identical elements in the process, method, article or system including the element.
