[0040] Hereinafter, exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. It should be apparent to those skilled in the art that the following described embodiments are only part of the embodiments of the present application and are not intended to limit the present application, and a variety of modifications can be made thereto without departing from the scope of the present application.

[0041] In the related art, in order to ensure that a device can run safely after starting, it is necessary to force an operator to manually adjust a non-self-resetting operating element to an initial state before starting. The safe running of the device completely depends on the proficiency of the operator, and there is a great security risk. Taking a non-self-resetting operating element throttle knob as an example, because the operator selects a suitable knob position during normal operation, and needs to maintain the device in this state for work, a self-resetting type knob cannot be used. When the engine is turned off, the key switch can be directly operated to complete the operation, without the need to force the throttle knob to be adjusted to the lowest speed position. At the next start, the key switch can be directly operated to complete the operation. Then, the device starts to work in a short time to the state of the last rotation position of the throttle knob. However, the last rotation position of the throttle knob is not necessarily suitable for the work requirement this time, and therefore the operator needs to manually adjust the throttle knob to the lowest speed position before starting the device, which has a high requirement for the operation of the operator. If the operator forgets to adjust the throttle knob, the device runs with a security risk.

[0042] To solve the above problems, the embodiment of the present application provides a start self-protection scheme, which shields the operation signal of a non-self-reset operation element which does not meet the preset start position limit requirement when the device starts, and controls the device to run according to the first operation signal corresponding to the non-self-reset operation element when the non-self-reset operation element meets the preset start position limit requirement, so as to ensure the safe start and normal running of the device.

[0043] The start self-protection scheme will be described below in combination with the embodiments and the drawings.

[0044] Firstly, Figure 1 The structure of the start self-protection system provided by the embodiment of the present application is shown in the figure. As shown in the figure, Figure 1 The start self-protection system includes a control unit 10 and one or more non-self-reset operation elements 20 (only one non-self-reset operation element 20 is shown in the figure), and the non-self-reset operation element 20 is connected with the control unit 10. The control unit 10 is used to detect the current operation position of the non-self-reset operation element 20 when the device starts, judge whether the current operation position meets the preset start position limit requirement, wherein the preset start position limit requirement refers to the operation position of the non-self-reset operation element 20 which is limited to ensure the safe start of the device when the device starts, and if the current operation position does not meet the preset start position limit requirement, the operation signal output by the non-self-reset operation element 20 is shielded, and the device is controlled to run according to the first operation signal corresponding to the non-self-reset operation element 20 when the non-self-reset operation element 20 meets the preset start position limit requirement (for details, see the method embodiment below).

[0045] In the above start self-protection system, the non-self-reset operation element 20 is an operation element used by the operator to control the device to run. In the embodiment of the present application, the non-self-reset operation element 20 includes but is not limited to a throttle knob, a travel operation handle, etc. The control unit 10 is a hardware for collecting information and performing logical processing, such as a controller, a programmable hardware with information input and output, etc.

[0046] In addition, the start self-protection system can also include an information indicating element 30, and the information indicating element 30 is connected with the control unit 10. After shielding the operation signal output by the non-self-reset operation element 20, the control unit 10 can send the self-protection information of the non-self-reset operation element 20 whose operation signal is shielded to the information indicating element 30, and display the self-protection information to the operator through the information indicating element 30, so as to prompt the operator to adjust the operation position of the non-self-reset operation element 20.

[0047] The self-protection method performed by the control unit 10 when the device starts will be described below in combination with the method embodiment.

[0048] Figure 2is a flowchart of a self-protection method when a device is started, provided by an exemplary embodiment of the present application. The embodiment can be applied to the self-protection system described above, as shown in Figure 2 The self-protection method when the device is started includes the following steps:

[0049] In step 201, when the device is started, the current operating position of the preset operating element is detected.

[0050] The preset operating element is a non-self-resetting operating element.

[0051] In an embodiment, the current operating position of the preset operating element can be detected by using a sensor for gear detection, and a corresponding sensor can be set according to different types of preset operating elements. For example, an accelerator knob is used as an example for illustration. The accelerator knob is usually divided into a mechanical pull wire type accelerator knob and an electronic throttle type accelerator knob. When the accelerator knob is a mechanical pull wire type accelerator knob, a pull wire type displacement sensor is installed at the fixed end of the accelerator pull wire. When the knob is rotated, the pull wire is stretched or contracted, the sensor converts the linear displacement of the pull wire into an electrical signal, and the specific operating position is obtained by corresponding the electrical signal size. When the accelerator knob is an electronic throttle type accelerator knob, a Hall sensor is built into the accelerator knob, a magnetic steel is installed on the knob shaft, and the Hall sensor senses the change of the magnetic field when the knob is rotated, and outputs a pulse signal or a linear voltage signal, which corresponds to the specific operating position.

[0052] In another embodiment, considering that the operating signal output by the preset operating element corresponds to the operating position, the current operating position can be determined by detecting the operating signal output by the preset operating element. For example, the corresponding relationship between the operating signal and the operating position of the preset operating element is set in the control unit in advance. Accordingly, the current operating position of the preset operating element is detected, including: obtaining a second operating signal output by the preset operating element; and determining the current operating position corresponding to the second operating signal according to the corresponding relationship between the operating signal and the operating position. Thus, the current operating position is detected by the operating signal, which can avoid setting related sensors and reduce hardware costs.

[0053] In step 202, it is determined whether the current operating position meets the preset starting position limitation requirement.

[0054] The preset starting position limitation requirement refers to the operating position of the non-self-resetting operating element that is limited to ensure the safe starting of the device when the device is started.

[0055] Specifically, the preset start-up position limitation requirement is preset in the control unit, and the control unit compares the current operation position of the preset operation element with the operation position defined by the preset start-up position limitation requirement after detecting the current operation position of the preset operation element. If they are the same, it is determined that the current operation position meets the preset start-up position limitation requirement; otherwise, it is determined that the current operation position does not meet the preset start-up position limitation requirement.

[0056] It should be noted that the preset operation element can be one or multiple (including two). When the preset operation element is multiple, since the operation position requirements of different preset operation elements can be different, each preset operation element corresponds to a preset start-up position limitation requirement. The control unit can identify the operation element according to the identification of the preset operation element, and then select the corresponding preset start-up position limitation requirement.

[0057] As described above, the operation signal and the operation position have a corresponding relationship, so the current operation position can be judged based on the operation signal whether it meets the preset start-up position limitation requirement.

[0058] Correspondingly, judging whether the current operation position meets the preset start-up position limitation requirement includes: judging whether the second operation signal matches the first operation signal; if the second operation signal matches the first operation signal, it is determined that the current operation position meets the preset start-up position limitation requirement; if the second operation signal does not match the first operation signal, it is determined that the current operation position does not meet the preset start-up position limitation requirement.

[0059] In step 203, if the current operation position does not meet the preset start-up position limitation requirement, the operation signal output by the preset operation element is shielded, and the device is controlled to run according to the first operation signal corresponding to the preset operation element when the preset start-up position limitation requirement is met.

[0060] Shielding the operation signal output by the preset operation element can be understood as: the control unit does not control the device to run according to the operation signal output by the preset operation element. Specifically, the control unit does not receive the operation signal output by the preset operation element; or the control unit receives the operation signal output by the preset operation element, but does not output the control signal corresponding to the operation signal.

[0061] In this step, the control unit shields the operation signal output by the preset operation element, protects the start of the device, and at the same time forces to output the control signal corresponding to the above-mentioned first operation signal to the device, so as to ensure that the device can normally run even in the case that the current operation position of the preset operation element does not meet the preset start-up position limitation requirement.

[0062] In some embodiments, the method further includes: if the current operation position meets the preset start-up position limitation requirement, controlling the device to run according to the operation signal output by the preset operation element.

[0063] In some embodiments, the method further comprises: prompting the operator with self-protection information of the preset operating element; wherein the self-protection information is used to indicate that the operation signal output by the preset operating element is shielded.

[0064] For example, after shielding the operation signal output by the non-self-resetting operating element, the control unit can send self-protection information of the non-self-resetting operating element to the information indicating element, so as to display the self-protection information to the operator through the information indicating element, and prompt the operator to adjust the operating position of the non-self-resetting operating element.

[0065] When the device is started, the control unit automatically starts the self-protection function to execute the steps in the self-protection method provided in the embodiments of the present application. In this process, the control unit detects the current operating position of the preset operating element in real time, and determines whether the preset operating position meets the preset start-up position limit requirement. However, when the preset operating element is adjusted to the operating position meeting the preset start-up position limit requirement, if the control unit still starts the self-protection function, the above real-time detection and determination operation will increase the power consumption of the control unit. Therefore, it is necessary to close the self-protection function. In some embodiments, closing the self-protection function comprises: detecting that the preset operating element is adjusted to the operating position meeting the preset start-up position limit requirement, and then closing the self-protection function; or receiving a self-protection function closing signal, and then closing the self-protection function. For the latter, for example, a separate switch or an operating device such as a touch screen can be provided, and the self-protection function closing signal can be triggered by turning on the separate switch or clicking the self-protection closing button on the touch screen, and then the self-protection function closing signal is sent to the control unit. The control unit closes the self-protection function in response to the self-protection function closing signal.

[0066] In addition, the control unit can also close the self-protection function when it is detected that the operating position of the preset operating element changes (i.e., the operating position at the current time is different from the operating position when the device is started, which is not limited to the operating position meeting the preset start-up position limit requirement). This is because after the device is started, the control unit will forcibly control the device to run according to the operation signal corresponding to the operating position meeting the preset start-up position limit requirement, which is equivalent to the operating position of the preset operating element when the device is started being located at the operating position meeting the preset start-up position limit requirement. After the device is stably running, the operator needs to adjust the preset operating element to the target operating position required by the device operation, and at this time, the preset operating element can be directly adjusted to the target operating position without being adjusted to the operating position meeting the preset start-up position limit requirement first. Therefore, the control unit can close the self-protection function when it is detected that the operating position of the preset operating element changes, and control the device to run according to the operation signal output by the preset operating element.

[0067] Further, the method further comprises: detecting whether the self-protection function is closed; if the self-protection function is not closed, controlling the device to operate according to the first operation signal; and if the self-protection function is closed, canceling the shielding of the operation signal output by the preset operation element and controlling the device to operate according to the operation signal output by the preset operation element.

[0068] If the self-protection function is not closed, it indicates that the operator has not adjusted the operation position of the preset operation element, and at this time, the device is controlled to operate according to the operation signal corresponding to the preset start position limit requirement, so as to ensure the operation safety and the safe start of the device. If the self-protection function is closed, it indicates that the device is safely started and the operation is safe, and the device is controlled to operate according to the operation signal output by the preset operation element, so as to enable the device to operate safely and normally.

[0069] The self-protection method for starting the device provided in the embodiment can detect the current operation position of the non-self-reset operation element when the device starts, and judge whether the current operation position meets the preset start position limit requirement. If the current operation position does not meet the preset start position limit requirement, it indicates that the current operation position of the non-self-reset operation element is not located on the operation position limited for ensuring the safe start of the device, so that the operation signal output by the non-self-reset operation element is shielded, to avoid the security risk in starting the device. Meanwhile, the device is controlled to operate according to the first operation signal corresponding to the non-self-reset operation element when the preset start position limit requirement is met, to ensure the normal operation of the device when it starts. Thus, the self-protection method for starting the device provided in the embodiment can reduce the operation requirement of the operator before starting the device, that is, the operator does not need to adjust the non-self-reset operation element to the operation position meeting the preset start position limit requirement before starting the device, and can ensure the safe start and normal operation of the device.
