Abstract
Description
Technical Field
[0001] This utility model relates to the field of angle grinder control system technology, and in particular to a wireless remote control system for a shared angle grinder. Background Technology
[0002] With the rapid development of industrialization and the construction industry, angle grinders, as portable power tools, have been widely used in metal cutting, grinding, rust removal, and other fields. Traditional angle grinders mainly rely on mechanical switches for on / off control, requiring users to manually start and stop the equipment. While this design is simple, improper operation or unsupervised operation during high-speed rotation can easily lead to safety accidents, potentially injuring the operator or those nearby.
[0003] However, some new angle grinders are beginning to adopt dual controls or touch switches. Currently, these safety measures are mostly limited to single-operation protection and fail to achieve real-time monitoring and data analysis of the overall equipment's working status, nor do they provide intelligent responses to abnormal conditions. Meanwhile, the rise of the sharing economy has driven the development of the tool-sharing market. The emergence of shared angle grinders requires equipment to not only possess basic working functions but also intelligent management capabilities such as remote monitoring, fault warnings, and data feedback. Since shared equipment is typically located in different places, operators urgently need to monitor the working status of each piece of equipment in real time to enable timely scheduling, maintenance, and prevention of safety hazards.
[0004] In conclusion, angle grinder technology is currently at a critical stage of transformation from traditional mechanical control to intelligent and networked systems. Developing a shared angle grinder with embedded status monitoring and adaptive safety control functions will help address the shortcomings of traditional equipment in safety protection, real-time monitoring, and shared management, meet market demand for products with high safety and high management efficiency, and drive the industry towards intelligent manufacturing.

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1 This utility model provides a shared wireless remote control system for an angle grinder, including an angle grinder body, the angle grinder body integrating:
[0026] The wireless communication unit is connected to the user terminal and is used for the transmission of control commands or working data between the user terminal and the angle grinder body.
[0027] The control unit is electrically connected to the wireless communication unit and the angle grinder body, and is used to receive control commands from the user terminal and control the working status of the angle grinder body.
[0028] The detection unit, electrically connected to the control unit, includes a speed detection component, a current detection component, and a voltage detection component, and is used to detect the working status of the angle grinder body in real time.
[0029] The power supply unit is electrically connected to the angle grinder body, the wireless communication unit, the control unit, and the detection unit, and is used to supply power to the control system.
[0030] Specifically, the wireless communication unit transmits data in real time via a 4G network, and the detection unit converts the collected data such as rotation speed, current, voltage, and working time into digital signals. The wireless communication unit transmits the digital signals to the user's smart terminal via the 4G network, and the wireless communication unit adopts the LTE standard to ensure the stability and real-time performance of data transmission. The application on the user terminal receives and displays the transmitted data in real time, while providing a user-friendly interface for operation.
[0031] Specifically, the speed detection component includes a Hall sensor located on one side of the stator in the angle grinder body. The Hall sensor is electrically connected to the control unit. The Hall sensor monitors the speed of the angle grinder body. By sensing the change in the magnetic field on the rotor in the angle grinder body, the Hall sensor outputs a pulse signal. The control unit determines the real-time speed of the angle grinder body by calculating the number of pulses per unit time.
[0032] Specifically, the current detection component includes an H-bridge circuit and a resistor. The negative terminal of the H-bridge circuit is connected to the control unit and the positive terminal of the resistor. The negative terminal of the resistor is grounded. The current consumed by the H-bridge (i.e., the motor drive circuit) flows through the resistor. The current of the angle grinder body can be calculated by detecting the voltage and resistance value of the resistor.
[0033] Specifically, the voltage detection component includes a diode and resistors two, three, and four connected in series. A capacitor is connected in parallel with resistor four. The positive terminal of the diode is connected to a power supply. The positive terminals of resistor four and the capacitor are connected to the control unit. The negative terminals of resistor four and the capacitor are grounded. By dividing the voltage through resistors four, two, and three, the larger power supply voltage is proportionally scaled down to a smaller voltage, making it easier for the control unit to read.
[0034] Specifically, a varistor is connected in series between the diode and the power supply to provide voltage limiting protection for the voltage detection component.
[0035] Specifically, the control unit has a timing function to time the working time of the angle grinder body. The control unit is equipped with a timer, which periodically triggers an interrupt to accumulate the working time of the angle grinder body. The user can query the working time of the equipment at any time.
[0036] The working principle of this utility model is as follows: When in use, the angle grinder body is connected to a power source. The voltage detection component transmits the voltage information of the power supply to the control unit, activating the switching circuit. The drive circuit then outputs a PWM wave to control the motor. The current detection component transmits the current information of the angle grinder body during operation to the control unit. Furthermore, when the angle grinder body begins to rotate, the Hall sensor reads the rotor speed in real time and transmits it to the control unit. During operation, the control unit records data such as voltage, current, and speed, and uses its timing function to record the working duration. The working data is uploaded to the user terminal in real time via a wireless communication unit. The user terminal can easily view the current status and past data of the angle grinder body through a mobile device. Similarly, the user terminal can also send control commands to the control unit via the wireless communication unit, and the control unit will modify the working parameters of the angle grinder body to values suitable for the current working conditions according to the commands.
[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
