Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to an automatic handle recognition device. Background Technology

[0002] In existing mechanical equipment, when a machine is equipped with multiple identical handle ports, it is often difficult to quickly and accurately distinguish the inserted handles and output different energy according to the handles' needs.

[0003] To address this issue, the current common approach is to manually set the handle type and energy output parameters for each port. This method is not only inefficient but also prone to human error, failing to meet the high-efficiency operation requirements of automated and intelligent equipment. Furthermore, some existing technologies employ complex sensor arrays or communication protocols to identify handles, resulting in high equipment costs, complex structures, and poor compatibility. Therefore, there is an urgent need for a simple, reliable, and low-cost automatic handle identification and energy output solution. Utility Model Content

[0020] Figure 2 This is a flowchart illustrating the application method of the automatic handle recognition device provided by this utility model. Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Figure 1 This is a schematic diagram of the automatic handle recognition device provided by this utility model.

[0023] like Figure 1 As shown, this embodiment provides an automatic handle recognition device, including:

[0024] The handle is equipped with a recognition resistor;

[0025] The main body of the machine is provided with a handle socket, and a voltage acquisition circuit is provided inside the handle socket. The voltage acquisition circuit and the identification resistor form a closed loop.

[0026] In practical applications, each handle is equipped with a unique identification resistor, and the resistance value varies between different handles. This identification resistor serves as the handle's identifier and is used to generate a specific electrical signal when connected to the machine.

[0027] The machine body can have multiple identical handle ports, each connected to a voltage acquisition circuit. The voltage acquisition circuit is used to acquire the voltage value across the identification resistor after the handle is inserted.

[0028] In practice, the control unit of the machine body can be connected to a voltage acquisition circuit. The control unit can pre-store a mapping table of different voltage values, handle types, and corresponding energy output parameters. The control unit receives the voltage value transmitted by the voltage acquisition circuit, identifies the inserted handle type according to the mapping table, and then controls the interface corresponding to that handle to output the corresponding energy.

[0029] In practical applications, when using the automatic handle recognition device, the operator inserts the handle into the handle socket of the machine body. The recognition resistor on the handle forms a closed loop with the voltage acquisition circuit of the machine body. The voltage acquisition circuit collects the voltage value across the recognition resistor and transmits this voltage value to the control unit. After receiving the voltage value, the control unit searches for the corresponding handle type in a pre-stored mapping table. If a matching voltage value is found in the mapping table, the inserted handle type is determined; if no matching voltage value is found, an error message is issued. The control unit then calls the corresponding energy output parameters based on the recognized handle type and controls the interface corresponding to the handle to output the corresponding energy.

[0030] Figure 2 This is a flowchart illustrating the application method of the automatic handle recognition device provided by this utility model.

[0031] The following is combined with Figure 2 The automatic handle recognition device provided by this utility model will be described in further detail.

[0032] Firstly, the handle provided by this utility model can be specially customized. Specifically, different identification resistors with different resistance values ​​can be soldered into the inside of each handle. For example, the identification resistor of handle 1 has a resistance value of R1 = 100Ω, the identification resistor of handle 2 has a resistance value of R2 = 200Ω, the identification resistor of handle 3 has a resistance value of R3 = 300Ω, etc., and the resistance value information of each handle and its corresponding identification resistor is recorded.

[0033] Multiple identical handle ports are installed on the main body of the machine, and each handle port is connected to an independent voltage acquisition circuit. The voltage acquisition circuit uses a high-precision A / D converter chip to convert the acquired analog voltage signal into a digital signal before transmitting it to the control unit. The control unit uses a microcontroller, such as an STM32 series microcontroller. A mapping table is established and stored in the microcontroller's memory, showing the relationship between different voltage values, handle types, and corresponding energy output parameters. Taking handle 1 as an example, when handle 1 is inserted into the port, according to Ohm's law U = IR (assuming the machine provides a constant current of I = 0.01A), the voltage across its identification resistor is U1 = I × R1 = 0.01A × 100Ω = 1V. The mapping table records the voltage value 1V corresponding to handle 1, as well as the energy output parameters required for handle 1 (e.g., output voltage of 5V and output current of 2A). Similarly, the voltage values ​​and energy output parameters corresponding to other handles are recorded.

[0034] During use, when the handle is inserted into the handle socket on the machine body, the voltage acquisition circuit collects the voltage value across the identification resistor and transmits this voltage value to the control unit. Upon receiving the voltage value, the control unit searches for a matching item in the mapping table. If a matching voltage value is found, such as 1V, it is determined that handle 1 has been inserted. The control unit then controls the corresponding interface to output 5V voltage and 2A current according to the energy output parameters for handle 1 in the mapping table. If no matching voltage value is found, the control unit issues an error message via the display screen or indicator light, reminding the operator to check the handle connection.

[0035] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate, and the components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs. Those skilled in the art can understand and implement this without any creative effort.

[0036] Through the above description of the embodiments, those skilled in the art can clearly understand that each embodiment can be implemented by means of software plus necessary general-purpose hardware platforms, and of course, it can also be implemented by hardware. Based on this understanding, the above technical solutions, in essence or the part that contributes to the prior art, can be embodied in the form of a software product. This computer software product can be stored in a computer-readable storage medium, such as ROM / RAM, magnetic disk, optical disk, etc., including several instructions to cause a computer device (which may be a personal computer, server, or network device, etc.) to execute the methods of various embodiments or some parts of embodiments.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
