Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and in particular relates to a customizable cascaded sensor and electronic equipment. Background Technology

[0002] With the continuous development of flexible electronics technology, belt sensors have emerged. They can be applied to irregular surfaces and arranged in different ways to measure signals in different ranges.

[0003] In related technologies, wires can be etched on a polyimide base tape and discrete sensing elements (such as signal transmitters and signal receivers) can be soldered on, or conductive ink can be used to print sensing units, thereby preparing a tape sensor.

[0004] However, the dimensions of the aforementioned belt sensors are pre-set and cannot be adjusted according to the actual application scenario, resulting in poor application flexibility. Utility Model Content

[0005] This application provides a customizable cascaded sensor and electronic device, which solves the problem in the prior art that the length of the belt sensor cannot be adjusted according to the actual application scenario, resulting in poor application flexibility.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0008] The processor is located at one end of the connecting strip and is connected to each of the sensing units;

[0009] Each of the sensing units is arranged sequentially on the connecting strip, and each of the sensing units is connected in series through a detachable interface and an electrical wire or communication bus.

[0010] For each of the sensing units, the sensing unit includes a storage module for storing the address code of the sensing unit;

[0011] If any of the sensing units is disconnected from its adjacent sensing unit, the processor reallocates the address code according to the number and position of the remaining sensing units connected to the processor.

[0016] Each of the sensing units corresponds to at least one of the light sources;

[0017] Each of the light sources is connected in series with the corresponding sensing unit. When the sensing unit detects a reflected signal, the light source corresponding to the sensing unit emits light. The reflected signal is formed by reflecting the detection signal emitted by the sensing unit.

[0018] Optionally, the sensing unit includes: a signal transmitter and a signal receiver;

[0019] For each of the light sources, the light source is located between the signal transmitter and the signal receiver, or the light source is located on the side of the signal transmitter away from the signal receiver, or the light source is located on the side of the signal receiver away from the signal transmitter.

[0020] Optionally, each of the sensing units is arranged at equal intervals.

[0021] Optionally, the scalable cascaded sensor further includes: a reflector;

[0022] The reflector is detachably mounted on the back of the connecting strip and is used to deflect the propagation paths of the detection signal and the reflected signal when the cuttable cascaded sensor is mounted in reverse.

[0023] Optionally, the scalable cascaded sensor further includes: an orientation sensor;

[0024] The orientation sensor is connected to the processor and is used to send orientation data to the processor.

[0025] Optionally, the customizable cascaded sensor further includes: a communication interface;

[0026] The communication interface is connected to the processor and is used for data interaction with the processor.

[0027] Secondly, embodiments of this application provide an electronic device, including: a data processing module and a plurality of customizable cascaded sensors as described in any one of the first aspects, wherein the data processing module is connected to each of the customizable cascaded sensors and is used to control each of the customizable cascaded sensors to perform detection.

[0028] This application provides a customizable cascaded sensor. It features a processor and at least one sensing unit mounted on a connecting strip. The processor is located at one end of the connecting strip and connected to each sensing unit, which are arranged sequentially on the strip. These sensing units are connected in series via a detachable interface and electrical wires or a communication bus. Each sensing unit includes a storage module for storing its address code. If any sensing unit is disconnected from an adjacent sensing unit, the processor reassigns the address code based on the number and position of the remaining sensing units connected to it.

[0034] In the following description, specific details such as particular system architectures and technologies are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application can also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known sensor technologies, sensor algorithms, and sensors are omitted so as not to obscure the description of this application with unnecessary detail.

[0035] The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “the,” “the,” and “the” are intended to also include expressions such as “one or more,” unless the context clearly indicates otherwise.

[0036] See Figure 1 , Figure 1 This is a schematic diagram of the structure of an electronic device involving a customizable cascaded sensor according to an embodiment of this application. The electronic device may include a data processing module 110 and multiple customizable cascaded sensors 120.

[0037] The data processing module 110 can be connected to each of the customizable cascaded sensors 120. The data processing module 110 can control each customizable cascaded sensor 120 to perform detection, and measure the user's height or the size of the obstacle based on the reflected signals received and transmitted by each customizable cascaded sensor 120.

[0038] Specifically, the data processing module 110 can control multiple cascaded sensors 120 to periodically emit multiple sets of detection signals. When any cascaded sensor 120 detects a reflected signal formed by the reflection of the detection signal, it can feed back the received reflected signal to the data processing module 110.

[0039] Correspondingly, the data processing module 110 can analyze the received reflected signals to determine whether there is a user or an obstacle in front of the electronic device, and measure the user's height or the size of the obstacle based on the continued received reflected signals.

[0040] Furthermore, if a user passes by an electronic device, the cascaded sensors 120, arranged vertically and extending laterally, can detect whether the user is moving or stationary. Accordingly, the data processing module 110 can determine whether the user is moving or stationary based on the reflected signal, and calculate the user's speed when the user is moving.

[0041] Furthermore, the horizontally arranged and vertically extended cascaded sensors 120 can measure the user's height and transmit corresponding reflected signals to the data processing module 110, which can then determine the user's height data based on the received reflected signals.

[0042] For example, such as Figure 2A and Figure 2B As shown, Figure 2AThis is a schematic diagram of a data processing module proposed in an embodiment of this application. Figure 2B This is a schematic diagram of a customizable cascaded sensor module proposed in an embodiment of this application.

[0043] See Figure 2A The data processing module 110 may include multiple pins. Specifically, pin 1 (VCC) is the positive power supply (3.3 volts (V)); pin 2 (GND) is the power supply ground potential; pin 3 (IR_TX) is used to connect to the data pin (Data) of the transmitting module and output a PWM modulation signal; pin 4 (IR_RX) is used to connect to the data output pin (Out) of the receiving module and input the demodulated digital signal; pin 5 (SCL) and / or pin 6 (SDA) are optional serial peripheral interfaces (Inter-Integrated Circuit, I2C) for communication with external controllers; pin 7 (Data_Out) is a serial port output (TX) for transmitting sensing position information to the light strip controller; pin 8 (Data_In) is a serial port input (RX) for receiving configuration commands (such as reassigning IDs after trimming); and pin 9 (CLK) is the cascade interface clock line for synchronizing data transmission between multiple modules.

[0044] See Figure 2B The customizable cascaded sensor 120 may include an IR Transmitter (TR) module and an IR Receiver (RX) module, both of which include multiple pins.

[0045] Specifically, for the transmitting module, pin 1 (VCC) is the positive power supply (typically 3.3V / 5V), used to power the signal transmitter and (e.g., infrared emitting diode); pin 2 (GND) is the power supply ground potential, which can form a current loop; pin 3 (Data) is the data input, used to receive the PWM signal from the data processing module 110 in order to control the transmission strength and frequency (e.g., 38kHz carrier modulation); pin 4 (En) is the enable pin (optional), which can activate transmission when high and put the device into sleep mode when low to reduce power consumption.

[0046] For the receiving module, pin 1 (VCC) is the positive power supply (3.3V / 5V), used to power the signal receiver (such as the receiving chip); pin 2 (GND) is the power supply ground potential; pin 3 (Out) is the data output, which can output the demodulated digital signal (such as the intensity or frequency change of the infrared signal reflected by the human body); pin 4 (INT) is an optional interrupt output, which can trigger the interrupt of the data processing module 110 when a valid signal is detected.

[0047] Furthermore, the scalable cascaded sensors 120 may also include a light source, which can be controlled to emit light corresponding to the scalable cascaded sensors 120 that detected the user's approach when the light source is activated. For example, when a user passes by the electronic device, the horizontally arranged scalable cascaded sensors 120 may emit light sequentially.

[0048] It should be noted that in practical applications, multiple customizable cascaded sensors 120 can be arranged vertically or horizontally, or they can form a customizable cascaded sensor array. This application embodiment does not specifically limit the arrangement of each customizable cascaded sensor 120.

[0049] The following is a detailed introduction to the customizable cascaded sensors in the aforementioned electronic devices.

[0050] Figure 3 This is a schematic diagram of a customizable cascaded sensor provided in an embodiment of this application. See also... Figure 3 The customizable cascaded sensor may include: a connecting strip 310, a processor 320, and at least one sensing unit 330.

[0051] The processor 320 is located at one end of the connecting strip 310 and is connected to each sensing unit 330.

[0052] Furthermore, each sensing unit 330 is arranged sequentially on the connecting strip 310, and the sensing units 330 are connected in series. Correspondingly, the processor 320 can transmit data with each of the series-connected sensing units 330 through a detachable interface, combined with electrical wires or a communication bus.

[0053] In addition, for each sensing unit 330, the sensing unit 330 may include a storage module, which stores the address code of the sensing unit. The processor 320 can communicate with the corresponding sensing unit 330 according to the address code.

[0054] However, if any sensing unit 330 is disconnected from its adjacent sensing unit 330, the processor 320 can reallocate the address code according to the number and position of the remaining sensing units 330 connected to the processor 320, so that the remaining sensing units 330 connected to the processor 320 can still transmit data with the processor 320, thereby enabling the trimming of the cascaded sensors.

[0055] For example, the sensor unit 330 that is furthest from the processor 320 in the cascaded sensor can be cut off. After the sensor unit 330 that is furthest from the processor 320 is cut off, it will no longer be connected to the processor 320. However, the remaining multiple sensor units 330 are still connected to the processor 320 in series and can still transmit data with the processor 320.

[0056] Specifically, during the process of trimming the sensing unit 330, at least one sensing unit 330 can be trimmed from the end of the connecting strip 310 away from the processor 320, according to the length of the cascaded sensor required for the current scenario, based on the detachable interface between each sensing unit 330.

[0057] Accordingly, after at least one sensing unit 330 is cut off, if the processor 320 detects that it is unable to communicate with each sensing unit 330 according to the address code corresponding to each sensing unit 330 that is preset, then the processor 320 can determine that at least one sensing unit 330 has been cut off.

[0058] Therefore, the processor 320 can communicate with the remaining connected sensing units 330 to determine the number of the remaining sensing units 330, and then reallocate address codes for each sensing unit 330 according to the determined number.

[0059] Furthermore, the processor 320 can also redetermine the measurable size range of the cascaded sensor based on the number of remaining sensing units 330 and the pre-set distances between them. For example, the starting point can be the location of the processor 320, and the measurement range corresponding to the trimmed cascaded sensor can be determined by combining the distance between the sensing units 330 and the processor 320 with the distances between the individual sensing units 330.

[0060] Furthermore, the sensing unit 330 may include a signal transmitter 331 and a signal receiver 332, wherein the signal transmitter 331 and the signal receiver 332 may be connected in series. For example, the sensing unit 330 may be connected to the processor 320 via the signal transmitter 331 and to an adjacent sensing unit 330 via the signal receiver 332; or, the sensing unit 330 may be connected to the processor 320 via the signal receiver 332 and to an adjacent sensing unit 330 via the signal transmitter 331.

[0061] In addition, each sensing unit 330 can be arranged at equal intervals to improve the accuracy of measurements taken by the sensing units. Similarly, the signal transmitters 331 and signal receivers 332 in the sensing units 330 can also be arranged at equal intervals, such that the distance between the signal transmitter 331 and each adjacent signal receiver 332 is equal, and the distance between the signal receiver 332 and each adjacent signal transmitter 331 is also equal.

[0062] Furthermore, the surfaces of the signal transmitter 331 and the signal receiver 332 of each sensing unit 330 are covered with a wide-angle lens, which can increase the angle at which the signal transmitter 331 emits the detection signal and increase the range of the signal receiver 332 receiving the reflected signal, thereby improving the detection range of the electronic device.

[0063] In one alternative embodiment, see Figure 4 , Figure 4 This is a schematic diagram of another customizable cascaded sensor provided in an embodiment of this application. The customizable cascaded sensor may further include: multiple light sources 340.

[0064] Each sensing unit 330 may correspond to at least one light source 340.

[0065] Specifically, each light source 340 can be connected in series with the corresponding sensing unit 330. When the sensing unit 330 detects the reflected signal, the light source 340 corresponding to the sensing unit 330 emits light. The reflected signal is formed by the reflection of the detection signal emitted by the sensing unit 330.

[0066] It should be noted that for each light source 340, the light source 340 may be located between the signal transmitter 331 and the signal receiver 332, or the light source 340 may be located on the side of the signal transmitter 331 away from the signal receiver 332, or the light source 340 may be located on the side of the signal receiver 332 away from the signal transmitter 331. This application embodiment does not specifically limit this.

[0067] For example, see Figure 4 The sensing unit 330 has two light sources 340. One light source 340 is located between the signal transmitter 331 and the signal receiver 332, and the other light source 340 is located on the side of the signal receiver 332 away from the signal transmitter 331.

[0068] Corresponding to the fact that each sensing unit 330 can be arranged at equal intervals, each light source 340 can also be arranged at equal intervals, such that the distance between each light source 340 and its adjacent light source 340 is equal. Furthermore, if the light sources 340 are interspersed among the sensing units 330, each sensing unit 330 can also be arranged centrally between two adjacent light sources 340. The embodiments of this application do not specifically limit the arrangement of each light source 340.

[0069] It should also be noted that the location of the light source 340 does not overlap with the path of the signal transmitter 331 emitting the detection signal and the path of the signal receiver 332 receiving the reflected signal, which can prevent the light source 340 from affecting the detection signal and the reflected signal.

[0070] In another alternative embodiment, the scalable cascaded sensor may further include a reflector.

[0071] The reflector is used to reflect the detection signal and the reflected signal, causing the propagation paths of the detection signal and the reflected signal to be deflected.

[0072] Furthermore, the reflector can be detachably mounted on the back of the connecting strip to deflect the propagation paths of the detection and reflected signals when the cascaded sensors are mounted in reverse. Accordingly, after installation, the reflector can be positioned in the propagation path of the detection signal emitted by the sensing unit 330 to reflect the detection signal, thereby altering the propagation path of the detection signal.

[0073] Specifically, when the scalable cascaded sensor is installed in reverse, the detection signal emitted by the sensing unit 330 can be reflected by the reflector, thereby enabling the detection of the space behind the scalable cascaded sensor.

[0074] It should be noted that the angle between the reflector and the connecting strip 310 can be adjusted according to the actual situation, and this application embodiment does not impose a specific limitation on this. For example, the angle between the reflector and the connecting strip 310 can be 45 degrees.

[0075] In yet another alternative embodiment, the cascaded sensor can also include an orientation sensor.

[0076] The orientation sensor can be connected to the processor 320 to send orientation data to the processor 320. For example, if the orientation sensor is a gravity sensor, the installation orientation of the customizable cascaded sensors can be adjusted using the data transmitted by the gravity sensor during the installation process.

[0077] Furthermore, if the cascaded sensors that can be cut to size are not installed parallel to the horizontal or vertical direction, the measured data can be corrected based on the data provided by the orientation sensor during application. Alternatively, the cascaded sensors can also adjust the reference parameters measured by the sensing unit based on the data provided by the orientation sensor. This application does not specifically limit the method by which the cascaded sensors can correct the measured data.

[0078] In yet another alternative embodiment, such as Figure 3 As shown, the customizable cascaded sensor may also include: a communication interface 350.

[0079] The communication interface 350 can be connected to the processor 320 for data interaction. For example, after receiving data from the processor 320, the communication interface 350 can forward the received data to the data processing module 110 in the electronic device, or it can forward the data transmitted by the data processing module 110 to the processor 320.

[0080] In summary, the scalable cascaded sensor proposed in this application embodiment involves placing a processor and at least one sensing unit on a connecting strip. The processor is located at one end of the connecting strip and connected to each sensing unit, which are arranged sequentially on the connecting strip. Each sensing unit is connected in series via a detachable interface and electrical wires or a communication bus. Each sensing unit includes a storage module for storing its address code. If any sensing unit is disconnected from an adjacent sensing unit, the processor reassigns the address code based on the number and position of the remaining sensing units connected to the processor. The method provided in this application embodiment allows for the reduction of the length of the scalable cascaded sensor by cutting at least one sensing unit when the length needs to be adjusted, thereby improving the flexibility of using the scalable cascaded sensor.
