Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

In the present application, where the contrary is not intended, the use of directional terms such as "upper, lower, top, bottom" generally refer to the orientation as shown in the drawings, or to the component itself being oriented in a vertical, perpendicular, or gravitational direction; likewise, for ease of understanding and description, "inner and outer" refer to the inner and outer relative to the profile of the components themselves, but the above directional words are not intended to limit the invention.

The Hall sensor is used for converting the magnetic induction intensity into voltage to be output, and the output voltage of the Hall sensor is related to the displacement of the Hall sensor. If the Hall sensor is abnormal, the output voltage of the Hall sensor cannot feed back the real displacement condition. Therefore, it is necessary to detect the abnormal condition of the hall sensor in time, so as to realize accurate detection and control based on the hall sensor. The hall sensor generally has three pins, namely an input voltage terminal, a ground terminal and an output voltage terminal, wherein the output voltage terminal is used for outputting an output voltage related to displacement. In the related art, it is general to detect a voltage of an output voltage terminal of the hall sensor and determine that the hall sensor is abnormal when the output voltage terminal does not output a signal. However, the above detection method is generally only suitable for a scenario where the output voltage terminal is damaged or the input voltage terminal has no voltage input, and for a scenario where the ground terminal is damaged, the output voltage terminal of the hall sensor may continuously output the maximum voltage, so that an abnormal condition of the hall sensor cannot be found, and a detection result is incorrect.

Example 1

Referring to fig. 1, the abnormality detection circuit 10 includes a voltage sampling module 100 and an output module 200, where fig. 1 is a schematic structural diagram of the abnormality detection circuit 10 according to an embodiment.

The input end of the voltage sampling module 100 is connected to the input voltage end of the hall sensor 20 to be detected. The voltage of the input voltage terminal of the hall sensor 20 is directly related to the abnormal state of the hall sensor 20. Specifically, if there is no abnormality in the hall sensor 20, the voltage at the input voltage end is a preset voltage; if there is an abnormality in the hall sensor 20, the load on the input voltage terminal is disconnected, that is, there is no voltage on the input voltage terminal. The abnormality includes a breakdown of the output voltage terminal, no voltage input to the input voltage terminal, and a breakdown of the ground terminal. Therefore, by connecting the input terminal of the voltage sampling module 100 with the input voltage terminal of the hall sensor 20, it is possible to accurately know whether there is an abnormality in the hall sensor 20. The voltage sampling module 100 is configured to control an on-off state between an output terminal and a ground terminal of the voltage sampling module 100 according to a voltage at an input voltage terminal of the hall sensor 20. That is, the voltage sampling module 100 can be understood as a switch controlled by the input voltage terminal.

For example, the voltage sampling module 100 may control the output terminal of the voltage sampling module 100 to be conducted with the ground terminal when the voltage of the input voltage terminal is the preset voltage; and when no voltage is present at the input voltage terminal, the voltage sampling module 100 controls the output terminal of the voltage sampling module 100 to be disconnected from the ground terminal. For another example, the voltage sampling module 100 may control the output terminal of the voltage sampling module 100 to be disconnected from the ground terminal when the voltage of the input voltage terminal is the preset voltage; and when the input voltage end has no voltage, the voltage sampling module 100 controls the output end of the voltage sampling module 100 to be conducted with the ground end. That is, the mapping relationship between the input voltage terminal and the on-off state is not limited in this embodiment, and may be a one-to-one mapping. Moreover, the specific structure of the voltage sampling module 100 for implementing the control function is not limited in this embodiment.

The output module 200 is connected to an output end of the voltage sampling module 100, the output module 200 is configured to generate a detection result signal corresponding to an on-off state, and the detection result signal is used to represent whether the hall sensor 20 is abnormal. The voltage of the signal received by the output module 200 is different from the voltage of the detection result signal, and the voltage of the detection result signal can be adapted to the input voltage requirement of the back-end processor. Specifically, when further control is required based on an abnormal condition of the hall sensor 20, the signal needs to be received and processed by an external processor. However, the voltage sampling module 100 can only control the on-off state, and does not have a voltage regulation function, and the voltage at the output terminal of the voltage sampling module 100 often cannot be accurately adapted to the input voltage requirement of the back-end processor. Therefore, the output module 200 can process the received voltage signal and output a corresponding detection result signal.

In this embodiment, by collecting the voltage of the input voltage terminal of the hall sensor 20 in real time, the voltage sampling module 100 can represent the abnormality of the hall sensor 20 as the on-off state between the output terminal and the ground terminal. Further, the output module 200 may generate a detection result signal according to the on-off state, so as to further convert the abnormality of the hall sensor 20 into a detectable electrical signal, and implement timely detection and output of the abnormal state of the hall sensor 20.

Fig. 2 is a second schematic structural diagram of the abnormality detection circuit 10 according to an embodiment, and referring to fig. 2, in one embodiment, the voltage sampling module 100 includes a light emitting diode and a light sensitive element.

Specifically, the anode of the light emitting diode is connected to the power voltage terminal, the cathode of the light emitting diode is connected to the input voltage terminal of the hall sensor 20 as the input terminal of the voltage sampling module 100, and the light emitting diode is configured to emit light when there is no abnormality in the hall sensor 20 and to be turned off when there is an abnormality in the hall sensor 20. One end of the light sensitive element is connected to the ground, the other end of the light sensitive element is connected to the output module 200 as the output end of the voltage sampling module 100, and the light sensitive element is used for being turned on or off under the brightness control of the light emitting diode. Further, in fig. 2, the photosensitive element is exemplified as a phototransistor. When the photosensitive element is a phototriode, the light-emitting diode and the phototriode jointly form an optocoupler structure, and the output and the input of the optocoupler structure are insulated. Therefore, the optical coupling structure has strong anti-interference capability and better isolation performance, and can effectively improve the reliability of the abnormality detection circuit 10. It is understood that, in other embodiments, the photosensitive element may also be a photodiode, and the present embodiment is not limited.

In one embodiment, the detection result signal includes a high level signal and a low level signal, and the output module 200 is configured to generate the low level signal when the on-off state is on, and generate the high level signal when the on-off state is off. Specifically, when the hall sensor 20 is not abnormal, the voltage at the input voltage end of the hall sensor 20 drives the light emitting diode to emit light with a certain wavelength, and the light is received by the phototriode to generate a photocurrent, so that the phototriode is turned on, and a low level signal is output. When the hall sensor 20 is abnormal, the load below the input voltage end of the hall sensor 20 is disconnected, no voltage difference exists between the two ends of the light-emitting diode, and the light-emitting diode is disconnected and does not emit light, so that the phototriode is not conducted, and a high-level signal is output.

With continued reference to fig. 2, in one embodiment, the output module 200 includes a first resistor R1 and a second resistor R2. The first resistor R1 is connected to the power voltage terminal and the output terminal of the voltage sampling module 100. The second resistor R2 is connected to the output terminal and the ground terminal of the voltage sampling module 100, respectively.

The voltage of the power supply voltage terminal may be, for example, 5V. The resistance values of the first resistor R1 and the second resistor R2 may be set according to the requirement of the input voltage processed at the back end. Based on the above configuration, the specific operation principle of the abnormality detection circuit 10 is as follows. When the hall sensor 20 is not abnormal, the voltage at the input voltage end of the hall sensor 20 drives the light emitting diode to emit light with a certain wavelength, and the light is received by the phototriode to generate a photocurrent, so that the phototriode is conducted, and a low level signal is output. When the voltage sampling module 100 outputs a low level signal, the second resistor R2 is short-circuited, so that the voltage of the detection result signal output by the output module 200 is 0V. When the hall sensor 20 is abnormal, the load below the input voltage end of the hall sensor 20 is broken, no voltage difference exists between the two ends of the light-emitting diode, and the light-emitting diode is disconnected and does not emit light, so that the phototriode is not conducted, and a high-level signal is output. When the voltage sampling module 100 outputs a low level signal, the first resistor R1 and the second resistor R2 form a voltage dividing circuit, so that the voltage of the detection result signal output by the output module 200 is not 0V. For example, if the voltage at the power supply voltage end is 5V and the resistances of the first resistor R1 and the second resistor R2 are equal, the voltage of the detection result signal output after voltage division is 2.5V.

Example 2

In the present embodiment, a sensor circuit is provided, fig. 3 is a schematic structural diagram of the sensor circuit according to an embodiment, and referring to fig. 3, the sensor circuit includes a magnetic member (not shown), a hall sensor 20, the abnormality detection circuit 10 as described above, and a processor 30, and the embodiment of fig. 3 is described by taking an example in which the sensor circuit includes the abnormality detection circuit 10 according to the embodiment of fig. 2.

Specifically, the hall sensor 20 is disposed at a corresponding position of the magnetic member, and the specific positions of the magnetic member and the hall sensor 20 may be determined according to a usage scenario. The hall sensor 20 is used to output a sensing signal corresponding to data to be measured. The data to be measured is determined according to the usage scenario of the hall sensor 20. For example, the magnetic member may be a trigger member disposed on the brake plate or the handle in the brake assembly, and accordingly, the hall sensor may be configured to sense a distance or an angular displacement from the magnetic member and output a sensing signal for cutting off the driving power supply circuit when the distance or the angular displacement satisfies a preset condition, so as to implement a braking function. Correspondingly, the data to be measured is the distance or angular displacement between the Hall sensor and the magnetic part. Or, the magnetic part can also be a part in the accelerator assembly, such as can install in the handle of electric scooter, correspondingly, hall sensor can be used for the angular displacement with the magnetic part to output the sensing signal that different angular displacements correspond, in order to realize the speed control function. Correspondingly, the data to be measured is the angular displacement of the Hall sensor and the magnetic part.

The processor 30 is connected to the output voltage terminal of the hall sensor 20 and the abnormality detection circuit 10, respectively, and the processor 30 is configured to determine whether the hall sensor 20 is abnormal according to a detection result signal output by the abnormality detection circuit 10, and acquire data to be detected according to a sensing signal when the hall sensor 20 is not abnormal. Alternatively, the processor 30 may be, for example, a Micro Controller Unit (MCU), and the MCU may include a digital logic circuit therein, and implement the above functions through the digital logic circuit. That is, when the detection result signal is at a low level, the detection result signal enables the processor 30 to acquire the data to be measured according to the sensing signal by the processor 30. When the detection result signal is high, the detection result signal cannot enable the processor 30. It can be understood that, the related art may be referred to as a signal processing method for acquiring the data to be measured according to the sensing signal, and the embodiment is not limited thereto.

Fig. 4 is a second schematic diagram of the sensor circuit according to an embodiment, and referring to fig. 4, in one embodiment, the sensor circuit further includes an alert module 40 connected to the processor 30. The processor 30 is also configured to generate an alert signal when there is an abnormality in the hall sensor 20. The warning module 40 is configured to receive the warning signal and send a warning according to the warning signal. The level state of the warning signal may correspond to the level state of the detection result signal. Optionally, the level state of the warning signal may be the same as the level state of the detection result signal, or may be opposite to the level state of the detection result signal, and this embodiment is not limited. Further, the inversion of the level states may be achieved by an inverter in the processor 30. In this embodiment, by setting the warning module 40, the user can be warned in time when the hall sensor 20 is abnormal, so that the user can be informed of the error of the output voltage of the current hall sensor 20, and the user can be prompted to maintain or replace the hall sensor 20.

In one embodiment, the alert module 40 includes a buzzer. The buzzer is connected to the processor 30, and is configured to receive the warning signal and send a sound warning according to the warning signal. Specifically, fig. 5 is a third schematic structural diagram of a sensor circuit according to an embodiment, and referring to fig. 5, the warning module 40 may further include an input circuit of a buzzer, and the input circuit is used to provide stable and reliable driving voltages BELL + and BELL-for the buzzer. The input circuit of the buzzer comprises a capacitor and a sixth resistor R6, two ends of the capacitor are respectively connected with the processor 30 and the grounding end in a one-to-one correspondence manner, two ends of the sixth resistor R6 are respectively connected with the processor 30 and a preset voltage end in a one-to-one correspondence manner, and the voltage of the preset voltage end can be 3.3V. The capacitor may be charged and discharged according to the signal output from the processor 30 to provide a driving voltage to the buzzer.

In one embodiment, the alert module 40 includes a display screen. The display screen is connected to the processor 30, and is configured to receive the warning signal and send an image warning according to the warning signal. It can be understood that compared with a buzzer, the display screen can output richer and more visualized information, and therefore under some scenes, the user can be clearly warned by sending image warning through the display screen.

With continued reference to FIG. 5, in one embodiment, the sensor circuit further includes a third resistor R3, a fourth resistor R4, and a fifth resistor R5. One end of the third resistor R3 is connected to the output voltage end of the hall sensor 20, the fourth resistor R4 is connected to the ground and the other end of the third resistor R3, and the fifth resistor R5 is connected to one end of the third resistor R3, which is used for connecting the fourth resistor R4, and the processor 30. In this embodiment, by providing the third resistor R3, the fourth resistor R4 and the fifth resistor R5, the voltage of the output voltage end of the hall sensor 20 can be adjusted to be adapted to the requirement of the input voltage of the processor 30, so that the processor 30 can stably and accurately receive the sensing signal.

Example 3

This embodiment provides a scooter, and the scooter of this embodiment is electric scooter. Fig. 6 is a schematic structural diagram of a scooter according to an embodiment, and referring to fig. 6, the scooter includes a frame, a throttle assembly and a brake assembly (not shown) movably connected to the frame, and the scooter further includes a driving controller 50 and a sensor circuit as described above.

The hall sensor 20 and the magnetic part in the sensor circuit can be arranged in the accelerator assembly or the brake assembly. The processor 30 is further configured to output a sensor abnormality signal when there is an abnormality in the hall sensor 20 to be measured. The driving controller 50 is connected to the processor 30 of the sensor circuit, and receives the sensor abnormality signal transmitted from the processor 30, and stops the sensing signal output from the hall sensor 20 controlled by the presence of the abnormality in response to the sensor abnormality signal. Specifically, since the hall sensor 20 is abnormal, the voltage at its output voltage terminal is always the maximum value. If the Hall element at the brake assembly is damaged, the vehicle can be always in a brake state and cannot normally run. If the Hall element at the accelerator assembly is damaged, the running speed may suddenly increase to a maximum value during starting or running, so that certain potential safety hazards exist. Therefore, in the present embodiment, by accurately detecting whether one or more of the output voltage terminal of the hall sensor 20 is damaged, the input voltage terminal has no voltage input, and the ground terminal is damaged, and outputting the sensor abnormal signal when detecting that the above-mentioned condition occurs, the driving controller 50 stops being controlled by the sensing signal output by the hall sensor 20 having the abnormality, the driving controller 50 is effectively prevented from being controlled by the erroneous sensing signal, thereby improving the safety of the scooter. It is to be understood that the scooter can be configured with a power mode and a non-power mode in which the user can use the scooter when there is an abnormality in the hall sensor 20.

With continued reference to fig. 6, in one embodiment, the number of the hall sensors 20 in the sensor circuit is multiple, and the number of the abnormality detection circuits 10 is also multiple, and the hall sensors 20 are respectively connected to the abnormality detection circuits 10 in a one-to-one correspondence. The processor 30 is configured with a plurality of input ports, which are connected to the plurality of abnormality detection circuits 10 in a one-to-one correspondence, respectively. The processor 30 is configured to receive the detection result signals from the input ports, and output the to-be-detected data corresponding to each hall sensor 20 when there is no abnormality in each hall sensor 20 to be detected. The driving controller 50 is used for adjusting the running speed of the scooter according to the received data to be measured. In this embodiment, when a plurality of abnormality detection circuits 10 are provided, the processor 30 can monitor a plurality of hall sensors 20 at the same time, thereby further improving the safety of the scooter.

Further, when the sensor circuit includes the warning module 40, the processor 30 may also perform different types of prompts according to the abnormal hall sensor 20, for example, different icons may be prompted in the display screen. For another example, the buzzer may be controlled to provide audible prompts at different volumes. Based on the prompt mode, the flexibility of the warning can be further improved, and the use experience of a user is improved.

It is obvious that the above described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, a person skilled in the art can make changes or changes in other different forms without creative work, and all should belong to the protection scope of the present invention.
