[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] The following is for reference. Figures 1 to 5 This invention describes a forklift starting device based on identity recognition in an embodiment of the present invention.

[0027] This application discloses a forklift starting device based on identity recognition, including: a control host 1, an antenna device 2, an actuator 3, and a wireless key.

[0028] The control host 1, antenna device 2, and actuator 3 are all installed inside the forklift. Antenna device 2 and actuator 3 are electrically connected to the control host 1, and antenna device 2 is signal-connected to the wireless key. Antenna device 2 sets the identification calibration area by transmitting wireless signals. The control host 1 and the wireless key both store the driver's identification information. When the wireless key is within the identification calibration area, antenna device 2 receives the identification signal emitted by the wireless key and transmits the identification signal to the control host 1 for verification. If the verification is successful, the control host 1 sends a start command to actuator 3 to start the forklift. If the verification fails, the control host 1 issues an alarm and prohibits the start operation.

[0029] In this embodiment, the control host 1 integrates a high-performance microprocessor and a large-capacity storage chip. It communicates with other systems of the forklift via interfaces such as serial ports and CAN bus, and can store authorized driver information and forklift operation data. The antenna device 2 is installed in a suitable location in the cab. It can transmit wireless signals to set an identification calibration area. When the driver enters the identification calibration area with a wireless key, the wireless device can receive the driver identification device signal and transmit it to the control host 1 for verification. The actuator 3 is connected to the forklift starting circuit. After successful authentication, it connects the circuit to achieve contactless starting and can also control the power supply of some functional modules.

[0030] Compared to existing forklift starting methods, the forklift starting device of this embodiment can identify the driver's identity by arranging it in the forklift, preventing unauthorized personnel from using the forklift and effectively protecting the safety of personnel and equipment. At the same time, it can also achieve contactless starting of the forklift, effectively simplifying the forklift starting process and significantly improving the efficiency of forklift use.

[0031] In some embodiments, the high-performance microprocessor is an STM32F103C8T6, which has powerful computing capabilities and rich peripheral interfaces to meet the complex control requirements of the system.

[0032] In some embodiments, the control host 1 is internally equipped with an EEPROM (Electrically Erasable Programmable Read-Only Memory) module for pre-storing authorized driver identity information and forklift usage records. By arranging the EEPROM storage module, not only can authorized driver identity information be pre-stored, but detailed forklift usage information can also be recorded. This facilitates management personnel in formulating equipment maintenance plans, such as determining maintenance cycles based on usage duration; and facilitates personnel performance evaluation, such as tracking the time and frequency of forklift use by each driver, effectively improving fleet management efficiency. Logistics companies can use this data to optimize forklift scheduling and rationally arrange driver work.

[0033] In some embodiments, the identification and marking area includes a sensing area and an activation area, with the sensing area being larger than the activation area; the control host 1 has three operating states: hibernation, standby, and operation; when the wireless key is in the sensing area, the control host 1 enters the standby state from the hibernation state; when the wireless key is in the activation area, the control host 1 enters the operation state from the standby state; conversely, when the wireless key leaves the activation area, the control host 1 enters the standby state from the operation state; and when the wireless key leaves the sensing area, the control host 1 enters the hibernation state from the standby state.

[0034] In this embodiment, in the hibernation state, the chip core of the control host 1 is in a stopped working state, and the peripheral components of the control host 1 are also stopped working. In the standby state, the control host 1 starts to initialize the start area detection and start input status detection. After the command that meets the conditions is issued, the control host 1 controls the key relay output. In the working state, the control host 1 controls the key relay output to control the start of the vehicle.

[0035] In this embodiment, when the driver enters the sensing area with the wireless key, the antenna device 2 receives and identifies the specific identification signal emitted by the wireless key. This signal is processed and transmitted to the control host 1. After receiving the valid identification signal and confirming that the signal parameters match the pre-stored authorization information, the control host 1 switches from the sleep state to the standby state. At the same time, it establishes an information association with the driver, completes the identity verification and authorization process, and prepares for the forklift to start. When the driver enters the starting area with the wireless key and sits on the forklift seat, closing the seat switch, the control host 1, upon receiving the signal that the driver is on the forklift seat, determines that the driver is ready and randomly switches from the standby state to the working state. Simultaneously, it controls the actuator 3 to start the forklift.

[0036] When the driver leaves the forklift seat or leaves the starting area with the wireless key, the seat switch is turned off, and the control unit 1 determines that the driver has left the operating area and randomly switches from the working state to the standby state. When the driver leaves the sensing area with the wireless key, the control unit 1 cannot establish an information association with the driver and randomly switches from the standby state to the hibernation state to stop related control operations and ensure that the forklift is in a safe stationary state.

[0037] In some embodiments, the sensing area is a spherical region with a diameter of 2m centered on the antenna device 2; the activation area is a spherical region with a diameter of 1m centered on the antenna device 2.

[0038] In some embodiments, the antenna device 2 and the wireless key exchange signals via PKE wireless communication technology (keyless entry system). By employing PKE wireless communication technology, the antenna device 2 can quickly and accurately receive identification signals and transmit them to the control host 1 for verification.

[0039] In some embodiments, the control host 1 integrates a small battery. When the control host 1 is in sleep or standby mode, the small battery powers the control host 1; when the control host 1 is in operation, the forklift battery powers the control host 1. Integrating a small battery inside the control host 1 solves the power consumption problem caused by frequent state switching of the control host 1.

[0040] This utility model also proposes a forklift, including the aforementioned forklift starting device based on identity recognition, which can realize contactless starting, significantly improve the efficiency of forklift use, and at the same time, can identify the driver's identity, effectively preventing unauthorized personnel from driving the forklift, thus significantly improving the safety of forklift use.
