As used in this specification, the term "or" is generally used to include the meaning of "and / or", unless the context clearly indicates otherwise, and the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. It can be directly connected or indirectly connected through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements.

[0021] Please refer to Figure 1 , an embodiment of the present invention provides a method for remote management of electric tools, the method comprising the following steps: S1: Get the status information of the power tool; Among them, the status information includes the fault information of the tool body and the charging and discharging information of the battery. Specifically, the fault information of the tool body refers to the temperature information generated when the motor is overheated or the abnormal overcurrent and overvoltage information, as well as the abnormal vibration and speed imbalance information of various components of the power tool. These fault information are generally monitored by temperature sensors, voltage sensors, current sensors, vibration sensors and speed sensors; and the battery pack charging and discharging information includes charging and discharging time information, charging and discharging number information, battery capacity information, charging and discharging current information and temperature information. These information are also monitored by temperature sensors, voltage sensors, and current sensors, and finally summarized and sent to the cloud for storage and forwarded to the user terminal; S2: Analyzes the status information and assigns it to users based on permission parameters; Among them, the user terminal processes the fault information and charge and discharge information to obtain the maintenance parameters of the power tool; specifically, after receiving the fault information and charge and discharge information forwarded by the cloud, the user terminal compares them to determine whether they exceed the preset threshold. If they do not exceed the preset threshold, relevant information will continue to be collected. If they exceed the preset threshold, the comparison results will be summarized into maintenance parameters and sent to the user. Users are divided into administrators, operators and manufacturers according to the authority parameters. Administrators have the authority to view all maintenance parameters and the functions of adding, deleting, modifying and checking the maintenance parameter viewing authority (that is, administrators have the authority to manage which maintenance parameters operators and manufacturers can view), while operators and manufacturers only have the authority to view some maintenance parameters.

[0022] S3: The user issues a remote management instruction based on the analyzed status information.

[0023] Among them, after checking the maintenance parameters, the user inputs a remote management instruction to the user terminal. Specifically, when the administrator finds that the tool body or battery pack has an abnormal condition through the maintenance parameters, the remote management instruction can be sent to the cloud, and the cloud will forward it to the tool end to execute the instruction. For example, when the motor is overheated, the administrator can send a remote management instruction with a command to shut down the power tool to stop the tool end from running to avoid accidents caused by continuing to work; at the same time, the remote management instruction can also include a command for the operator to view the cause of the overheating of the tool end. The operator can receive the remote management instruction through the tool end or view it through the user terminal. If the operator cannot solve the problem of motor overheating, the operator can feedback to the manufacturer, and the manufacturer will solve the problem; or, the administrator assigns the viewing authority of the maintenance parameters to the manufacturer, allowing the manufacturer to monitor the overheating of the motor, and let the manufacturer communicate with the operator through the user terminal to obtain a solution to the problem of motor overheating. The manufacturer can even guide the operator to repair or replace parts through digital technology (such as AR augmented reality), so that the operator can repair more easily. In addition, the manufacturer can regularly send maintenance and maintenance reminders to users to help users prevent failures. For example, regular cleaning, lubrication, and replacement of wearing parts. This enables manufacturers to achieve remote monitoring, fault prediction and maintenance plan optimization on the tool side.

[0024] Please refer to Figure 2 An embodiment of the present invention further provides an electric tool remote management system, including multiple tool terminals, a cloud, and a user terminal.

[0025] The tool end has a tool body and any equipment used in conjunction with the tool body. The tool body includes but is not limited to devices used for cutting, grinding, fastening, drilling and other operations.

[0026] The user terminal includes an unlimited number of mobile terminals and / or PC terminals, and any mobile terminal and any PC terminal application have the same operating functions, and the implementation logic is slightly different due to the difference in operating systems. The cloud is respectively connected to the tool terminal and the user terminal for information transfer and storage between the two. In some embodiments, the tool terminal also has a battery.

[0027] The equipment used in conjunction with the tool body includes structural parts that are directly or indirectly used for the equipment to realize its operation (for example, cutting, grinding, fastening, drilling, etc.). Among them, the structural parts directly used for the equipment include saw blades, saw blades, chains, grinding wheels, sockets, screwdriver heads and other accessories; the structural parts indirectly used for the equipment include handles, dust hoods, protective covers, lighting and other accessories.

[0028] See also Figure 2The tool end has an acquisition unit and a first transmission unit. The acquisition unit acquires status information of the tool end. Specifically, the acquisition unit includes a first acquisition unit for acquiring fault information of the tool body and a second acquisition unit for acquiring battery charge and discharge information. The acquired fault information and charge and discharge information are transmitted to the cloud by the first transmission unit. The cloud classifies and stores the fault information and charge and discharge information and forwards it to the user terminal.

[0029] Specifically, the cloud has a second transmission unit and a storage unit. When the first transmission unit on the tool end sends fault information and charge and discharge information to the cloud, the second transmission unit receives the information and stores it in the storage unit. The second transmission unit is coupled to the storage unit to store the fault information and charge and discharge information and sends it to the user terminal through the second transmission unit.

[0030] The mobile terminal and / or PC in the user terminal has a third transmission unit, an analysis unit and a display unit. The user terminal receives fault information and charge and discharge information through the third transmission unit and the analysis unit analyzes and processes the information to obtain maintenance information. The maintenance information is displayed to each user with different authority parameters through the display unit, and the user's identity is assigned by the identity management unit of the user terminal; according to the authority parameters, users are divided into administrators, operators and manufacturers.

[0031] In addition, the display unit is further configured to receive a remote management instruction input by a user, the selection of which is presented by the display unit and completed by a user's click (e.g., a touch click of a touch screen or a click of a mouse), and the scope of the remote management instruction is limited by the user's authority parameters. When the user selects a remote management instruction through the display unit, it is sent to the cloud through the third transmission unit and then forwarded to the tool end for execution.

[0032] In some embodiments, the first acquisition unit collects temperature information generated when the motor is overheated or abnormal overcurrent and overvoltage information, as well as abnormal vibration and speed imbalance information of various components of the power tool; the second acquisition unit collects battery charge and discharge time information, charge and discharge times information, battery capacity information, charge and discharge current information and temperature information. The first acquisition unit includes a temperature sensor, a voltage sensor, a current sensor, a vibration sensor and a speed sensor, and the second acquisition unit includes a temperature sensor, a voltage sensor and a current sensor.

[0033] Through the electric tool remote management method and system mentioned in the embodiments of the present invention, combined with the Internet of Things technology, the status information on the electric tool body and battery can be uploaded to the cloud in a timed or conditionally triggered manner. The user terminal can diagnose the current status of the tool body and battery through the analysis unit to achieve remote monitoring, fault prediction and maintenance plan optimization of the electric tool. This will greatly improve production efficiency and equipment reliability, reduce maintenance costs, and bring greater competitive advantages to users.
